Effect of Nematode on Tobacco

Effect of Nematode on Tobacco Tobacco 1.0 Introduction Tobacco (Nicotina tabacum L.) is one of the most important non- food crop and widely grown commercially (Akerhust, 1981). This plant had a high economic value and widely demanded throughout the world for the usage of the nicotine, cigarettes, cigars and other tobacco product (Akerhust, 1981). Nowadays, in Malaysia, Tobacco industry is very crucial in uplifting the socio-economic status of farmer in Kelantan, Terengganu, Kedah and Perlis. There were 20,524 farm families, 355 tobacco curers, 1300 grower and 25384 station workers. This industry generates about 150 million in income per year. 38% of the income goes to the farmers and 18% to the curers (http://www.malaysiayellowpages.net/mpi/details/TOBACCO.htm). This plant can give a stable income and therefore increased the income of farmer (Wells, 1987). Tobacco was cultivated as a rotation with the paddy for a side income (Anon, 1981). Tobacco plant can be infected by bacteria, fungus, virus, and parasitic nematode. Disease infection lower the tobacco yield and also quality. This research focused on effect of plant parasitic nematode on tobacco. Plant parasitic nematode can be found wherever tobacco is grown. The severity of the damage they caused depended on climate and soil type (Luc, Sikora et al. 2005). Nematode infection may lower the quality and yields. Annual report from North Carolina in 2008, showed Meloidogyne spp. it self cause loses around $2,505,126 in 2004, $1,596,452 in 2005, $ 1,772,819 in 2006, $1,542,864 in 2007, and $4,096,321 in 2008 while other nematodes cause $146,297 in 2004, $2281 in 2005, $529,188 in 2006 and $208,612 in 2008 (www.dowagro.com/soil/products/tobacco/economic.htm). In Malaysia, the effect of nematode on tobacco yield reduction has not been fully understand or revealed. Therefore, the objectives of this project were: To observe the effect of nematode on tobacco. To observe the relationship of soil physical properties on nematode population density and disease severity. 2.0 Literature review 2.1 Tobacco Tobacco was one of the most important non- food crop and widely grown commercially (Akerhust, 1981). This plant originated came from South America (Tso, 1972). However according to Gerstel (1961), Nicotina tabacum not occurring in wild state it was amphidiploids which come from hybridization of Nicotina sylvestris and Nicotina tomentosiformis. This plant has a high economic value and has been widely demanded throughout the world for the usage of the nicotine such as cigarettes, cigars and other tobacco product (Akerhust, 1981). This plant also important for the research purposes (Tso, 1972). Many researches have been done by using this plant mostly in Plant physiology and Genetics (Bateman Millar, 1966; Albersheim et. al., 1969; Kosuge, 1969). In Malaysia, Tobacco was first introduced in year 1959 by Malayan Tobacco Company (now known as Malaysia Tobacco Company, MTC) in Kelantan cultivation area for 8 hectares (Anon., 1976). Nowadays, in Malaysia, Tobacco industry has been very crucial in uplifting the socio-economic status of farmer in Kelantan, Terengganu, Kedah and Perlis. There were 20,524 farm families, 355 tobacco curers, 1300 grower and 25384 station workers. This industry generated about 150 million in income per year. 38% of the income goes to the farmers and 18% to the curers (Ministry of primary industry, 2010). This plant can give a stable income and therefore can increase the income of farmer (Wells, 1987). Tobacco is cultivated as a rotation with the paddy for a side income (Anon, 1981). However, product and quality of tobacco leaf are quite low due to encountering many problems, including diseases. For Tobacco cultivation, a deep and well drained soil is needed. This is where nematodes problem develop rapid ly (Luc, Sikora et al. 2005). 2.2 Nematodes related with the Tobacco Plant parasitic nematode can be found wherever tobacco is grown. The severity of the damage they caused may depended on climate and soil type (Luc, Sikora et al. 2005). Many tobacco producing countries are near or within the inter-tropical zone. The dominant nematodes that parasitize tobacco plant were Meloidogyne spp. (a root-knot nematode). Most of important species from this genus were M.arenaria, M.incognita, M.javanica, and M.hapla. M.incognita and M.javanica were important species in Malaysia. Other Meloidogyne spp., were rarely reported. Similarly, Pratylenchus spp. were also dominant species that parasitize tobacco plant (Kimpinski and Thompson 1990). Apart from Meloidogyne spp. and Pratylenchus spp., Tylenchorhynchus spp., Globodera spp., Ditylenchus dipsaci and Aphelenchus ritzemabosi were reported to parasitized tobacco plant in certain restricted area. Other nematodes such as Helicotylenchus, Rotylenchus, Scutellonema, Rotylenchulus sp., Tetylenchus and Crinomella sp. hav e been found to infect tobacco plant but not normally associated with losses. Some nematode species such as Xiphinema, Longidorus, Trichodorus, and Paratrichodorus have been reported to transmit viruse to tobacco (Luc, Sikora et al. 2005). Nematodes also may cause disease complex. For example Meloidogyne spp. a root-knot nematodes has been proved to increase the incident of Fusarium wilt even when their population were incapable to cause direct damage to the tobacco plant (Webster, 1972). Another example was interaction between Pratylenchus brachyurus (lesion nematode) and Phyptopthora parasitica var. nicotianae (cause black shank disease). Inagaki and Powell (1969) found that P. brachyurus caused more severe and rapid diseased development of black shank symptom than when the fungus alone. 2.3 Root-knot nematodes, Meloidogyne spp. 2.3.1 Distribution Meloidogyne spp. are always important parasites in tobacco cultivation, wherever the climate favours them (Nusbaum, 1960; Daulton, 1964; Barker et al., 1981; Rich et al., 1982). There were 61 species and two subspecies in this genus at the end of 1988 (Eisenback, 1985; Eisenback Hirschmann, 1991). Nowadays until year 2000 there were 80 species have been describing (Carneiro et al., 2000). Parasitism of Meloidogyne spp. was first reported by Tisdale (1922) in Florida. This genus was also a serious pest in Southern Africa in the late 1920s (Jack, 1927; NaudÑ?, 1929). Meloidogyne incognita and M. javanica were mostly found parasitize the tobacco plant. Their infection was very relying on the climate, since M.javanica had a higher tolerance towards drought and high temperature compared with M.incognita (Daulton Nusbaum, 1969, 1962; Taylor et al., 1982). Meloidogyne arenaria and M.hapla were the next mostly found to cause infection on tobacco plant. Meloidogyne hapla was reported to be found in the cooler parts of the world. Report from fields survey in Florida showed M.javanica was found in 65% of fields survey area, M.incognita 33% and M.arenaria was rarely found (Rich Garcia, 1985). Report from North Carolina showed M.arenaria population had increased gradually although M.incognita was the predominant species there. This observation also showed the same in South Carolina (Fortnum et al., 1984; Schmitt Barker, 1988). Apart from that, M.javanica and M.hapla was reported to be found in North Carolina. Reported showed that there were 64% of M.incognita and 29% of M.javanica to be found in Philippines (Madamba, 1981). Meloidogyne incognitagraham, M.microcephala, M.mayaguensis, M.cruciani, M.enterolobii, M.ethiopica, M.platani, M. themesi were also reported to parasitize reproduce tobacco plant but their importance was very restricted (Cliff hirschmann, 1984; Jepson, 1987; Rammah 1988; Rammah and Hirshmann, 1988). 2.3.2 General morphology The morphology of this genus were almost all same the except for some characteristic which usually were very useful for species identification. They were usually sexually dimorphic. Adult female have swollen, saccate bodies (pear shape like body). The size of female ranged in median length 0.44-1.30 mm and width about 0.33-0.70 mm (Eisenback, 1985). They have protrudes neck anteriorly while vulva and anus were located terminally. The female of this genus have pearly white body with moderately thick cuticle. Stylet were short, moderately sclerotized and protrusibly hollow. The stylet size was 10-24ÂÂ µm in length which consists of cone, shaft and knobs. The morphology of the stylet was quite varying between species in this genus. The morphology of stylet should be one of the supplemental characteristic to be observed for species identification. The stylet functions like hypodermic needle which was moved by protractor muscles. The shaped of the cone, shaft, and knobs also differ a mong female species in this genus. At the posterior of stylet knobs, there was dorsal esophageal gland orifices (DEGO). DEGO was the two sub ventral gland orifices open into the esophagus lumen. DEGO had a varied distance among species which also can be supplemental character for species identification. The excretory pore of the Meloidogyne spp. female situated anterior to median bulb valve plat and usually near stylet base. They also have two convoluted genital tracts. The major part of the total body content consists of two gonads which were very long and greatly convoluted. There were ovary with germinal zone and growth zone, narrow oviduct, globular spermatotheca and long uterus in each gonad. Spermatotheca were differing among species. Therefore this character can also be use for species identification. Apart from that, the cuticle in the perineal region of female from this genus forming a finger print-like pattern (the perineal pattern) which also had been use for species iden tification. This is because, the perineal pattern hold most characteristic of female such as tail terminus, phasmids, lateral lines, anus, and vulva which surrounded by cuticular striae or folds. They also have six large unicellular rectal glands situated in the posterior body region. These rectal glands were connected to the rectum. This gland produce very large amount of gelatinous matrix material. This material was excreted through the rectum and act as protective egg sac (Nickle, 1991). Different with the female, male of Meloidogyne sp. are vermiform. The size of the body vary between species which are about 700-2,000 ÂÂ µm (Eisenback, 1985). This is because the varying environmental condition existing during their development. Body of the male usually twisted through 180ÃÅ'Ã…   upon heat relaxation. The male stylet vary in size which are about 13-30 ÂÂ µm. The stylet and head of male from this genus are robust. Apart from that, size and shape of the stylet cone, shaft, and knobs can be use for species identification (Eisenback and Hirschmann, 1981). The location of DEGO is 2-13 ÂÂ µm posterior to the stylet knob base. The isthmus is short and most of the species have ventrally two overlapping gland lobe instead of normally three esophageal nuclei. The hemizonid located at the front to excretory pore. However some species the hemizonid located at the posterior of excretory pore. In normal male there is only one gonad while in sex-reversed males have two gonads. There is long vas deferens packed with developing sperm in the gonad. Among the species, the size of the spicules range from 19 to 40 ÂÂ µm. The spicules usually robust and the bursa are absent. Tail is short (hemispherical shape). There is also variation of tail shape between species (Nickle, 1991). A second stage juvenile was the infective stage of Meloidogyne sp. It has varied body length from 290 to 912ÂÂ µm (Eisenback, 1985). The head of second stage juvenile basically just same with the male. It has a delicate stylet with 8 to 18ÂÂ µm in length. The DEGO distance are varied among species with the distance mostly 2 to 8ÂÂ µm. The esophagus of the second stage juvenile is narrow with faintly outline procorpus. The median bulb is well defined. Median bulb has a large valve plate and three long ventrally overlapping glands that are use for molting and feeding. The second stage juvenile has a varied position of excretory pore. The hemizoid located posteriorly to the pore. The tail length of second stage juvenile varied among species. Usually the length is 15 to 100ÂÂ µm. At the end of the tail there is hyaline terminus. In this genus, second stage juveniles are group base on the tail length and tail shape (Whitehead, 1968; Jepson, 1984). Jepson (1987) showed that differences in either mean tail and or mean hyaline terminus are very large. These vast differences can be very useful to distinguish species within groups (Nickle, 1991). 2.3.3 Life cycle Meloidogyne sp. shows sexually dimorphism, which is the female are pyriform or saccate, while the males vermiform (Eisenback, 1987). The differences in body shaped between female and male occurred during the postembryonic development of Meloidogyne sp.. From the embryonic development, the egg hatched once to become first-stage juvenile and then molted as a second stage juvenile. The second-stage juvenile was infective stage. It moved into the soil and entered the root of suitable host plant. This second-stage juvenile then formed host-parasites relationship with the plant when it find preferred feeding site. The morphology of second-stage juvenile changed to flask-shape as it feeds on the special nurse cell. Then, without further feeding it molted three times into the third and fourth stage juvenile, and finally become an adult. The saccate adult female resumed feeding on the special nurse cell shortly after the last molt and continued to do so for the remainder of her life. The repr oductive system of both female and male of this genus developed into functional gonads during the postembryonic development (Triantaphyllou and Hirschmann, 1960). From the number of the gonad, we can differentiate the sexes. Females always have two gonads while males usually have one. During fourth-stage juvenile, the shape of saccate male juvenile changed to the vermiform adult males. The metamorphosis occurred in which the body elongates from saccate to a vermiform shape. Fully developed male emerges after the final molt of enclosed fourth-stage male which enclosed within the cuticles of second-stage and third-stage. The adult male leaved the root and move freely through the soil and it does not feed. The mode of reproduction determined the function of the male for mating. Depending on particular species reproduction whether amphimixis or parthenogenesis, the male enters the root searching for the female to mate or just remain in the soil and die. Temperature plays a vital role fo r the length of the life cyle. For example, the first adult female of M.incognita on Tomato appear 13-15 days after root penetration at temperature approximately 29 ÃÅ'Ã…  C, the female laid the first egg about 19-21 days after penetration (Triantaphyllou and Hirschmann,1960). The life span of female is much longer than the male from 2 to 3 month. 2.3.4 Effect of Meloidogyne spp. on Tobacco plant Meloidogyne sp. caused formation of galls on Tobacco root. Usually, second stages juvenile entered via behind the root cap which involves mechanical penetration by using stylet (Linford, 1942). According to Bird et.al, (1975), the penetration also involve some enzymatic action (cellulolytic or pectolytic) which secreted by esophageal gland. Then, the second-stage juvenile moved through the cortex to the region of cell differentiation. This differentiation cell was the feeding site for them which later transformed into highly specialized feeding cells called giant cells. This cell was the permanent feeding site for them (Hussey at al., 1994). According to Dropkin (1972) and Hussey (1987), the multinucleate giant cell was the result of the introduction of secretion produced by subventral esophageal gland cells of the feeding second stage juvenile. Giant cells serve as sourced of food. The nutrient from giant cells was transferred to the nematode (Jones and Northcote, 1972). According t o McClure (1977) these cells act as metabolic sink. These giant cells affected the function of the root as it caused extensive distortion and blocked of the vascular tissue which slowed water and nutrient transport. Therefore, the absorption of nutrient and water greatly reduced. Plant growth and yield may be suppressed as photosynthates were mobilized to the giant cells. Above- ground symptoms showed chlorosis of foliage and temporary wilting (premature wilting) when water stress occurred usually during drought or sunny day. Plant was stunted and the leaves were yellow and thin. The formation of gall was due to the root tissues around nematode and giant cells undergo hyperplasia and hyperthrophy. The worse was when secondary larval invasion occurred which caused the gall to coalesce and finally the root begins to decay (Nickle, 1991). Nematode also had the ability to form disease complex with other plant pathogens. The giant cell produced by root-knot nematode was highly suitable f or development of Fusarium wilt ( Porter and Powell, 1967). 2.4 Root lesion, Pratylenchus spp. 2.4.1 Distribution Pratylenchus spp. is migratory endoparasites root-lesion nematodes. This genus was just slightly less economic important compare with Meloidogyne spp. in the tropical and subtropical regions. However, some species from this genus were responsible for significant yield loss in some tobacco cultivation area. Pratylenchus pratensis, P.negletus, P.brachyurus and P.zae have been reported to parasitized tobacco in North America while in South Africa P.hexincisus, P.thornei, P.vulnus, P.brachyurus, P.minyus, and P.zae have recorded on tobacco (Milne, 1961; Honey, 1967). In Hungary, P.pratensis had been reported to parasitize tobacco cultivation. Pratylenchus penetrans was responsible to cause yield loss in Iraq. In some region in Canada, P.penetrans, P.crenatus, and P.neglectus were mostly found in tobacco fields (Mountain, 1954; Kimpinski et. al., 1976). Canter-Vissher (1969) had found Pratylenchus penetrans in New Zealand while Singh (1974) has found Pratylenchus zae in Trinidad. In gener al Pratylenchus brachyurus and P.zae are mostly found in tropical areas while P.penetrans, P.thornei, and P.minyus are common species in temperate regions (Webster, 1972). In Malaysia, this Pratylenchus sp. was locally important. However their distribution were not clearly report (Luc, Sikora et al. 2005). 2.4.2 General morphology In general the morphology of species in this genus was very similar. There was no marked sexually dimorphism in form of anterior region. Adults have body length range from 0.3 to 0.9 mm. Their body was rather stout. Because increasing of uterus volume and the presence of eggs, the gravid females were stouter than nongravid ones. The cuticle of this genus generally thin and shows fine transverse striation. There were four longitudal lines marking the lateral field. However, additional longitudal line may be present in the central zone. Because of cuticle of gravid female were quite stretch, the lateral field was indistinct. The head of this genus was low and flattened with lip region divided into two,three, or four annules. This annules was continuous with the body countour. Cephalic framework of Pratylenchus sp. was heavily sclerotized. The apical anule among most species were round except for P.brachyurus which was angular. There were three types of head structure that can be found under SEM (Corbett and Clark, 1983). The stylet of Pratylenchus sp. were quite short around 11-25 ÂÂ µm. The stylet was stout with well-developed basal knobs. There was tapering procorpus in the pharynx which was usually roundish median bulb. The isthmus was short which overlapped with the anterior end of the mid-intestine on the ventral side. There were three unicellular glands in the lobe. The length of the ventrosublateral was unequal (Seinhorst, 1971). At 2-4 ÂÂ µm behind the stylet base, there was orifice of the dorsal pharyngeal gland duct. There was no deirids in this genus. The oesophagus of both male and female was equally developed. The tail of male was short and dorsally convex-conoid. Female of Pratylenchus spp. are monoprodelph. The genital branch of most species in this genus occurred as a short sac which usually undifferentiated. The uterus of female often tricolumellar (Nickle, 1991). Different with male, female tail usually two to three anal body diameter long. The bisexual species in this genus, have oval or round spermatheca which was filled with sperm (Luc, Sikora et al. 2005). 2.4.3 Life cycle Some species in this genus reproduced sexually while most of them parthenogenetic. This migratory endoparasitic root lesion nematode fed and laid eggs in the root cortex. Most of them can be found in roots, rhizomes, or tubers and somehow can also be found in stem or fruits. Usually after penetrate the root; this endoparasitic nematode will multiply to very large numbers (10,000-35,000 specimens per 10 g of root). All the stage starting from second stage juvenile entered the root. However with unknown reason, they moved in the soil for some time and goes for a new host root. The female laid the eggs in the root and starting from there their whole life cycle is in that root. Usually, the life cycle was completed in 50-60 days (Nickle, 1991). 2.4.4 Effect of Pratylenchus sp. on Tobacco plant Pratylenchus sp. usually moved and fed on the root cortex. This activity caused disintegration of root cortex and leading to browning of the root tissue. This was known as brown root rot (Mountain, 1954). Symptoms of this disease were pruning-root, water soaked, and lesion on the root. If the infection occurred under aseptic conditions the symptoms showed less severe in the certain experimental condition (Mountain, 1954). The above ground symptoms showed that the stunted plant wilt prematurely and in worse condition died. Inagaki and Powell (1969) reported that this genus caused disease complex with the other plant pathogens. Pratylenchus.brachyurus showed to increase infection of Blackshank by wounding the root which served as entry site. 3.0 Material and method: 3.1 Soil sample: 24 soil samples were collected from Terengganu, Perlis and Kelantan state. Collected soil sample were naturally infested with nematodes and Fusarium spp. Soil samples were store in polyethylene bags. Soil sample were kept in moist condition and out of direct sunlight. 3.2 Tobacco seedling preparation: Sterilized seeds were sown to sterile sandy soil. (River sand). After sown, seedlings were kept out of direct sunlight. Fertilizer applied for twice a week via foliar application. After 30 days of nursery tobacco seedlings were transferred to each soil. 3.3 Inoculation of tobacco seedlings: 6 kg of soil samples (naturally infested) were transferred into plastic container (33x22x10 cm) with drains. Then, 30 days of healthy Tobacco seedlings were transferred to each soil container. Each soil samples were planted with 10 Tobacco seedlings. Fertilizer was applied twice a week via foliar application. Ground symptoms were observed everyday. Tobacco plants were all harvested after 6 weeks. 3.4 Plant observation: Harvested Tobacco plants were observed for the disease symptoms, size of the plant, number of leaf, leaf area, plant weight and disease severity index. Wet weight of Tobacco was measured by using a weigher. Plant size was determined by using ruler. Size of the plant was measured from crown up until shoots. Number of leaf was counted including the number of undeveloped leaf. Root gall disease severity index was determined by using following scale: 0= no root galls 1= 1-25% root galls 2= 26-50% root galls 3= 51-75% root galls 4= 75-100% root galls Disease severity index for root lesion was determined by using following index: 0= no root lesion 1= 1-25% root lesions 2= 26-50% root lesions 3= 51-75% root lesions 4= 75-100% root lesions Root then was stored in the FAA (Formaldehyde 100ml, Glacial acetic acid 50ml, Distilled water 850ml) suspension. 3.5 Isolation of nematode from soil samples: Isolation of nematode and soil inhabiting forms were extracted from soil samples by using Modified Baerman Funnel Technique (Hooper,1968; Viglierchio and Schmitt,1983).This was the simplest technique to isolate nematode and soil inhabiting forms. By using this technique we can avoid lack of oxygen and possibility of nematode lodging on the sloping funnel sides due to instead of using funnel we used a shallow dish. For this experiment instead of funnel a round shallow plastic container was used. A supporting gauze was put onto the plastic container with 0.5cm space between them. A milk filter paper with 50cc soil was put on the supporting gauze. Distilled water was added until the material was almost awash. After 5 days, the content of the dish was transfer into test tube. FAA was added to prevent population changes during storage. 3.6 Nematode counting: Nematode suspension collected via Modified Baerman Funnel was shaked. Then, 1ml was taken and transfer onto disposable plastic Petri dish. The number of all nematodes and parasitic nematodes were counted under a dissecting microscope by 5x to 10x magnification. Counting was repeated for three times. Percentage of parasitic nematodes was calculated. 3.7 Isolation of nematode from root: Nematode from root part was isolated by direct isolation. For root-knot nematodes especially female, the root tissue was carefully tease away with forceps and a fine needle to release the head and neck. Infected plant part was put onto slide and squash to check for the existence of nematode. The nematode then was stain with Phyloxine 1%. 3.8 Isolation of Fusarium spp. The root part was washed with running tap water to eliminate remaining soil particle. Then, the root was cut including healthy part (0.5cm). After that, the pieces of root were dipped in 70% ethanol for 1 minute. Then, the pieces were transferred into 5% sodium Hypochlorite solution to sterilize its surface for 3 to 5 minutes. The pieces then were transferred to sterilized distill water to rinse the pieces for 3 times each for 1 minute. After that, the plant pieces was put on sterile filter paper to eliminate excess water and then, were put on the acidified water agar medium. Finally, the dishes were sealed with parafilm and were incubated for a few days. Growing colonies were observed. 3.9 Soil pH: The soil pH was determined using a soil suspension (Rowell, 1994). 10 ÂÂ ± 0.1 gram of air dry soil sample was used in this experiment. 25 ml of water was added to the soil sample. Then, soil suspension was shacked occasionally by hand over 15 minutes period. The pH meter was calibrated at pH 4 and then pH 7 consistent reading. The soil suspensions were stirred and insert the electrodes. The pH was recorded after 30 second. 3.10 Soil moisture percentage: The water content of soils was determined by drying soil samples at 105 ÃÅ'Ã…  c (Rowell, 1994). For this experiment, soil samples were air dry for two days. Then, weight air dry soil samples for 10ÂÂ ±0.1 gram (W1). Instead of using a moisture can, aluminums foil was used. The aluminum foil was weighed (Wo). Then, weighed soil samples were put on the aluminum foil and placed them in an oven at 105 ÃÅ'Ã…  C for 24 hour. The weigh of soil sample with aluminum foil was weighed (W2). To calculate the weight of soil samples after oven dry the following formulae was applied: Weight oven dry soil (W3) = (W1+Wo)-W2 To calculate moisture percentage of soil samples, the following formulae was use: Moisture percentage (%) = W3/ (W2-Wo) x 100 3.11 Soil particle density: Determination of soil particle density involves the measurement of the volume of a known mass of particles. The soil is dispersed in water and all the air is expelled from the suspension. In a known volume of suspension the volume occupied by the particles is then found (Rowell, 1994). A clean and dry 50ml volumetric flask including stopper was weigh (Wo). Ten grams of oven dry soil samples were added into the volumetric flask. The volumetric flask was filled with distilled water until one-half full. The volumetric flask (without stopper) then was put in boiling water heating with a water bath for 30 minutes and gently agitated the content to prevent loss of soil by foaming. The volumetric flask and its content then cooled to room temperature. Distilled water was added up to the 50 ml mark. Water drop on the outer-side of the volumetric flask was wiped, insert the stopper and weighed (W2). The soil particle density was determined by using the following formulae: Soil particle density (Dp) = Soil mass/Particle volume Particle volume = Conical flask volume volume of water in flask Volume of water in flask = mass of suspension -mass of soil Mass of suspension = W2-W0 3.12 Soil texture analysis: Texture of soil samples were determined by using Hydrometer method (Bouyoucos, 1962; Page, 1982). Then, texture of soil samples determined by referring to USDA Textural triangle after calculation of the percentage of each particle (Brady, 1984). For this experiment, 50g of soil samples were placed into 600 ml beaker. Then, 100 ml of 6% hydrogen peroxide was added to decompose the organic matter. The mixture was kept remaining at room temperature overnight. After that, the beaker was placed on a hot plate at 90 ÃÅ'Ã…   C for 10 minutes. Then, 50ml of 1N Sodium hydroxide (NaOH) (dispersing agent) was added to the suspension and increase the volume to 400 ml with distilled water. The suspension was left for 20 minutes. Then, beaker was placed on a stirrer and stirred thoroughly for 10 minutes. The suspension was transferred to 1000 ml measuring cylinder. Then, distilled water was added to 1000 ml mark. Suspension was allowed to equilibrate thermally and the temperature was recorded. Mo uth of the measuring cylinder was covered with a parafilm and inverted for several times until the contents are thoroughly mixed. Mixture was left in a cool, shaded place. Then, the hydrometer was immediately into the suspension and reading was taken after 40 seconds until consistent reading. Hydrometer was removed and cleaned. The temperature of the suspension was recorded with thermometer. The thermometer was removed and remixes the suspension. Then, let the cylinder sit for 2 hours. At exactly 2 hours later, the hydrometer was again placed into the suspension and data was read. The temperature of the suspension was also seconded with thermometer. The actual reading must be corrected in order to get revised value depending upon the actual temperature. a. Add 0.36 g/L to hydrometer reading for each degree >20 ÃÅ'Ã…  C b. Subtract 0.36 g/L from hydrometer reading for each c. Density reading should also be corrected from the density of the dispensing solution (NaOH+ distilled water) without soil. These reading are must be subtract with the soil solution density reading. Finally, after calculating the percentage of each particle, use the USDA Textural triangle to determine the textural class of soil samples. Readings from specific gravity hydrometer was converted to soil g/l by using converting table (http://classic.globe.gov/fsl/html/templ.cgi?conversionlang=ar).

Kafka’s Metamorphosis: Vision of the Body

Through the metamorphosis of Gregor Samsa, Kafka not only traces modern man’s sense of alienation from his body, but also anticipates Postmodernist visions on identity—the way that identity relates to the body, and the social constructs of marginality and normality, that infallibly reminds us the works of Michel Foucault, who examined the disciplining and medicalization of body as a form of social control. Gregor Samsa’s sudden discovery of his transformed body is another form of the horrible confusion that Samuel Beckett later explores in his plays. There are no such pretty, healthy bodies in Beckett.His characters are infirm, decrepit figures that are, as Beckett described them, â€Å"falling to bits†. Some theorists of the Body trace the emphasis on ‘normal’ body to industrial capitalism, which required a standardized body for factory work and labeled the ‘different’ body as ‘abnormal’. This social conditioning can also be associated with the recent dreads like anorexia and bulimia in especially teenage girls, who in the desire to wear ‘size zero’ dress, that is extremely popular in America and to look ‘wonderfully thin’ endanger their lives with starvation.This is an example of how the market forces of capitalistic power play manipulate the concept of identity by constructing a ‘norm’ of the body. In spite of the traces of the modernist horror of fragmented identity, there is also an element of Postmodernist fantastic in Kafka’s tale; where the transformation of the body is more marvelous than terrible. The 2001 film Amelie had a protagonist who literally melts when her love interest leaves the restaurant in which she works without asking her for a date—unmistakably reminding the viewer Kafka’s vision of the Body as marvelous.

Black Males Receive Unfair Treatment “Discrimination in...

Although hatred, racism, and discrimination date as far as slavery one might say that it still suppresses African American Men until this day. Many forms of oppression still exist in this newly-made century. It has gotten so bad that the same oppression that has torn society has made its way into the school system. Could this be the major problem in the school system? â€Å" That was said aloud by, Arne Duncan, U.S. Secretary of education, The new guidance package is replete with data, highlighting, for example, that while African American students make up only 15% of public school systems, they represent 35% of students suspended once, 44% of students suspended twice, and 36% of students expelled†, as reported by Sarah Belton, Cartwright-Baron Attorney. It is rather disturbing if you ask me due to the fact that young black males may never get the education they need. What really seems to be the problem with the African American Men’s advance in the school system? The fact that teachers actually admit that they treat African American students differently is out of â€Å"stereotypical-reasoning†, meaning that if the student’s behavior is not of â€Å"good standard† then he would be kicked out. In most cases a black male could act out once and be disposed of as quick as a Caucasian male of the same behavior.

The Importance Of The National Association For Young...

The History of NAEYC By: Katie A. Wnukoski ECED 776 Dr. Shaffer 10/13/2016 Throughout our career as childhood educators, we observe the significance of the National Association for Young Children or NAEYC. It is recognized as â€Å"the nation’s premier organization for early childhood professionals-setting research based standards and providing resources to improve early childhood program quality† (Copple NAEYC, 2001) for teachers, students, and families. Despite exercising the knowledge of what NAEYC means for our classrooms and the students in them, some may not know who or how the organization was founded. Knowing the background of NAEYC is important because it has a reputable history of providing universities and educators with high quality, researched, information. In order to ascertain a further purpose to why these standards matter and the importance of NAEYC in education, we must learn its history and its founders. The standards written for NAEYC have been chosen through the appropriate research, to suite multiple situations and prac tices. By learning more in depth of the theorists and researchers that have made NAEYC what it is today, allows us to see origins of each standard and how they have developed from theory, into a standard in today’s education. Through learning its history, we can fully understand the connotation of seeking the best solutions for achieving successful educational outcomes through research and observation of needs.

Evidence-based Interventions for a Patient Suffering from Dementia Free Essays

Introduction Evidence-based practice has been promoted in all healthcare levels in the NHS (Department of Health, 2012). This is done to ensure that interventions are supported by current evidence in healthcare and have been found to be effective for most patients (Pearson et al., 2009). We will write a custom essay sample on Evidence-based Interventions for a Patient Suffering from Dementia or any similar topic only for you Order Now The use of evidence-based practice is rooted in the belief that patients should only receive quality care (Pearson et al., 2009). The same approach is used when caring for patients with mental health conditions. In the policy, No Health without Mental Health (Department of Health, 2012), the NHS has emphasised that patients suffering from mental health conditions should receive quality and evidence-based care. This brief aims to critically discuss the case of an 80-year old woman who is suffering from dementia and the different forms of interventions that could be applied to the case. Consistent with the Nursing and Midwifery Council’s (NMC, 2008) code of conduct, a pseudonym will be used to hide the identity of the patient. This brief discusses the purpose of evidence-based practice in managing patients with a progressive condition such as dementia. An investigation on the different forms of evidence-based interventions and their potential impact for promoting inclusion would also be presented. A discussion on interventions as means to develop a shared understanding of the patient’s needs would also be done. Legal, ethical and socio-political factors that influence the intervention process would also be explored. Finally, the last part discusses my role as a nurse in the intervention process. Using Evidence-based Interventions for Patients with Dementia The Nursing and Midwifery Council’s (NMC, 2008) Code of Conduct has stressed the importance of delivering quality evidence-based care that is patient-centred. Fitzpatrick (2007a) emphasised that the past model of evidence-based intervention relies only on current evidence from literature to support clinical decisions. Current studies that are of high quality are often used to inform current practices. Fitzpatrick (2007b; 2007c) exmphasised that nurses and other healthcare professionals should have the skills to critically assess the quality of a study and determine whether the findings are applicable to one’s current and future practice. Evaluating the strength of the evidence presented in a research study would require understanding of the search process and whether themes or findings from the study are credible or trustworthy (Polit and Beck, 2010). In recent years, this definition has included best practices, personal experiences of healthcare professional on providi ng care, experiences of colleagues, opinions of experts and current guidelines on a health condition (Fitzpatrick, 2007a; 2007b, 2007c; Greenhalgh, 2010). This new definition embraces other sources of evidence that could be used to help healthcare practitioners and patients make decisions regarding their care. Greenhalgh (2010) specifically points out that while there is reliance on good evidence from published studies, including the experiences of nurses, expert opinion and best practices to aid decision-making would ensure that patients receive quality care. Communicating evidence from published literature is also essential in helping patients decide on the best form of intervention. Morrisey and Calighan (2011) emphasises that effective communication is needed to convey findings of a study in a manner that is understandable to the patient. Successful use of evidence depends first on the quality of relationship between the healthcare providers and the patients (Croker et al., 2013. Kizer (2002) argued that for better care, the relationship between the healthcare professionals and the patients should be strengthened first. Kizer (2002) observe that, â€Å"this intimate relationship is the medium by which information, feelings, fears, concerns, and hopes are exchanged between caregiver and patient† (p. 117). In the UK, The National Institute for Health and Clinical Excellence (NICE, 2006) and the National Collaborating Centre for Mental Health (2007) have provided evidence-based guidelines on how to care for patients with dementia. These guidelines along with current literature, my own and my colleagues’ experiences, expert opinion and the experiences of my patient and her carers will form evidence on the best form of interventions for the patient. My patient’s name is Laura (not her real name). She is 80 years old with dementia, a condition that is progressive and characterized by deterioration of mental state, aggressive behaviour and agitation (Department of Health, 2009). A psychiatric consultant oversees the management of her condition. She has been receiving medications for her dementia but her GP and psychiatrist are discussing alternative drugs to reduce her anxiety level and regulate her sleeping patterns. She is diagnosed with type 2 diabetes and is mobilised with a frame following a broken hip. While she is still lucid and can communicate clearly, it is a challenge to care for her during nighttime when she becomes more anxious and shows signs of confusion. Patients with dementia suffer from progressive cognitive impairments (Department of Health, 2009) that could have an impact on how they receive information from their healthcare professionals and carers and in their adherence to medications. In the case of my patient, she is now showing signs of advanced dementia (NICE, 2006). This could be a challenge since her ability to refuse treatment or engage in healthcare decisions is severely reduced (Department for Constitutional Affairs, 2007). In the UK, the Mental Health Act 2007 (UK Legislation, 2007) and the Mental Capacity Act (Department for Constitutional Affairs, 2007) serve as guides on how to care for patients with mental health conditions such as dementia. These acts serve to protect the rights of the patient by locating a representative of the patient who could decide on her behalf. Hence, any interventions introduced for the patient should be agreed by the patient’s immediate family members or appointed guardian (Depart ment for Constitutional Affair, 2007). Since dementia is a progressive condition that could eventually lead to palliative care, the nurses have to ensure that the patient receives appropriate support during the trajectory of the condition. In my patient’s case, she needs immediate interventions for anxiety and sleep disturbance. She is also currently taking medications for her type 2 diabetes. The NICE (2006) guideline has stated the use of psychological intervention for patients with dementia. These include cognitive behavioural therapy, which will include the patient’s carers, animal-assisted therapy, reminiscence therapy, multisensory stimulation and exercise. Evidence-based Interventions and Potential Impact for Promoting Inclusion A number of studies (Casartelli et al., 2013; Monaghan et al., 2012; Ewen et al., 2012) have shown that exercise could improve the mobility of patients following hip surgery. Most of these studies use the randomised controlled trial study design, which ranks high in the hierarchy of evidence (Greenhalgh, 2010). This type of design reduces selection bias of the participants and increases the credibility of the findings of the study (Polit and Beck, 2010). The NICE (2013) guideline for fall also supports exercise intervention for improving patient’s mobility. My patient Laura is using a frame to aid her walking following a fall and an exercise intervention would improve her mobility. Considering that Laura is also suffering from anxiety, I counseled with the carer that we might consider an exercise intervention to both manage anxiety and improve mobility of the patient. This was well-received by the carer who expressed that they could help the patient with a structured walking e xercise. Meanwhile, cognitive behavioural therapy (Kurz et al., 2012; Hopper et al., 2013) has also been shown to be effective in reducing anxiety amongst patients and in regulating sleep behaviour. This form of intervention was also introduced to Laura and her carer. A programme was created where she would receive CBT on a weekly basis. It should be noted that the psychiatrist and the GP in the healthcare team are considering on alternative pharmacologic therapy to regulate sleeping behaviour and anxiety of the patient. While this might have a positive effect on the patient, it should be noted that medications for anxiety have side effects. For instance, the acetylcholinesterase inhibitors such as rivastigmine, galantamine and donepezil are known to have side effects on the cognition of patients (Porsteinsson et al., 2013; Moncrieff and Cohen, 2009). As a nurse and part of the team, I suggested to the team to consider the effects of pharmacologic interventions on the patient. Further, the NICE (2006) guideline also states that only specialists, that include GPs specialising in elderly care or psychiatrists, should initiate pharmacologic interventions. This guideline also emphasises that the Mini Mental State Examination (MMSE) score of the patient should be between 10 to 20 points. In Laura’s case, she is pro gressing from moderately severe dementia to its severe form. Introducing pharmacologic interventions might only worsen the cognitive state of Laura. Meanwhile, there is strong evidence from a systematic review (Filan and Llewellyn-Jones, 2006) on the effectiveness of animal-assisted therapy in reducing psychological and behavioural symptoms of dementia. A systematic review also ranks as high as randomised controlled trials in the hierarchy of evidence (Greenhalgh, 2010). Findings of Filan and Llewellyn-Jones (2006) also reveal that it can promote social behaviour amongst patients. This form of therapy was initially considered in Laura’s case due to its possible effects on the sleep behaviour of the patient. However, current evidence is still unclear on whether the effects could be sustained for prolonged periods. In application to my patient’s case, the use of animal-assisted therapy might be difficult to carry out since the patient has to depend on a carer for her daily needs. However, our team decided on using music therapy for the patient. Similar to animal-assisted therapy, there is also strong evidence on the e ffectiveness of music therapy in managing anxiety, depression and aggression amongst patients with dementia (Sakamoto et al., 2013; Wall and Duffy, 2010). Importantly, cognitive behavioural and music therapies and exercise interventions all promote inclusion of the patient in the care process (Repper and Perkins, 2003). In cognitive behavioural therapy, the patient and her carer receive support on how to manage anxiety and sleeping behaviour. Since carers are highly involved during CBT, there is a higher chance that the intervention would be successful (Hopper et al., 2013). It has been shown that carers of patients with chronic conditions such as dementia are also at risk of developing depression and anxiety (Department of Health, 2009). Smith et al. (2007) explain that this might be due to the realisation that the patient would not recover from the illness. Further, these carers have to prepare themselves for the patient’s end-of-life care. All these realisations could influence the carer’s own mental health (Smith et al., 2007). Hence, it is important that interventions are not only holistic for the patient, but should also include the carers in the process. Hence, implementing CBT would promote inclusion in practice (Wright and Stickley, 2013). The patient in my care is also suffering from type 2 diabetes. Pharmacologic interventions would include metformin and insulin therapy (NICE, 2008). Non-pharmacologic interventions include exercise, behavioural modification and diet. This presents a complex problem for Laura since it has been shown that elderly patients are also at greatest risk of malnutrition due to the aging process (Department of Health, 2009). Patients with dementia could experience feeding behavioural problems. When patients are admitted in hospitals, the new environment and lack of social interaction with peers could act as triggers in behavioural problems (Department of Health, 2009). Since patients might lack the cognitive ability to express themselves, this might present as aggressive behaviour (NICE, 2006). Hence, ensuring that Laura receives appropriate nutrition during her hospital stay could be influenced by changes in her behaviour. It is important that patients with type 2 diabetes do not only receive pharmacologic interventions but should also have sufficient diet. This is seen as a challenge in Laura’s case since she could experience feeding problems due to loss in cognitive abilities. For instance, she might be reminded on how to chew food or why she needs to eat (Department of Health, 2009). In patients with severe forms, the main aim of feeding is now focused on comfort feeding rather than allowing patients to eat the proper amount of food (Department of Health, 2009). Hence, managing Laura’s type 2 diabetes through proper feeding would be an added challenge to her care. Legal, Ethical and Socio-Political Factors that Influence the Intervention Process Decisions on the care and interventions received by the patient are influenced by several factors. First, the Mental Health Act 2007 (UK Legislation, 2007) states that patients with mental health condition could seek voluntary admission to hospitals and leave whenever they want. This Act also states that patients could only be forced to receive treatment in hospital settings if they are detained under this Act. Laura and her carer could refuse treatment or interventions at any point of her care and my team and I would respect her decision. Observance of this provision under the Mental Health Act would also be consistent with patient-centred care where patients are empowered to act for own benefit and to choose appropriate interventions. Apart from the legal aspects that influence the delivery of interventions, ethical issues should also be observed. In the ethics principle of beneficence, nurses and other healthcare practitioners should ensure that the interventions would be benefici al to the patient (Beauchamp and Childress, 2001). In Laura’s case, all the interventions cited previously have been shown to be beneficial to the patient. Only the pharmacologic interventions are associated with adverse and side effects for the patient (Popp and Arlt, 2011). Hence, as a nurse, I lobbied for inclusion of non-pharmacologic interventions instead of reliance on anticholinergic drugs to control the patient’s behaviour. In addition to beneficence, Beauchamp and Childress (2001) also add the ethics principles of autonomy, non-maleficence and justice. In Laura’s case, her autonomy would be respected. Allowing patients to participate in the decision-making process is crucial. However, patients with dementia suffer from cognitive impairments that could influence their decision-making ability (Wright et al., 2009). In accordance with the Mental Capacity Act 2005 (Department for Constitutional Affairs, 2007), the carers of Laura could be appointed to act on her behalf. In non-maleficence, the main aim of the interventions is to promote the health of the patient. There are no known side effects of the psychosocial and exercise interventions. Justice will be observed if Laura receives tailored-interventions that would address her needs. It is important that regardless of the patient’s background, religion, race, gender, ethnicity, she should receive healthcare interventions fit for her needs. This ethics principle is observed since a healthcare team has been addressing Laura’s healthcare needs. While all interventions are patient-centred, socio-political issues that could influence the interventions include the recent changes in the NHS structure where local health boards are primarily responsible for allocating funds to healthcare services (Department for Constitutional Affairs, 2007). Hence, if dementia care is not a priority in the local health board, health programmes for dementia might not receive sufficient funding. This could pose considerable problems for the elderly who are dependent on the NHS for their care. Laura has been receiving sufficient support for her mental health condition. This demonstrates that dementia care remains a priority in my area of care. A survey of the support system in my community reveals that support groups for carers are available. This is essential since supporting carers is also a priority in the NHS (National Collaborating Centre for Mental Health, 2007). Role of the Nurse in the Intervention Process On reflection of the case, I have a role to coordinate care with other team members and to ensure that the patient receives patient-centered care. As a nurse, I have to adhere to the NMC’s (2008) code of conduct and observe patient safety. Recognising that dementia is a progressive condition, I should also focus on interventions that not only addresses the current behavioural problems of the patient but also on preparing the carer and Laura’s family members on palliative care. The NICE (2006) guideline has stated that nurses have an important role in preparing patients of dementia and their family members on end-of-life care. This could be a highly stressful stage in the patient’s disease trajectory or could be one of acceptance and peace for the family. As a nurse, I have to ensure that interventions are appropriate to the stage of dementia that the patient is experiencing. Since nursing is a continuing process, I have to inform the family members that the patie nt will increasingly lose her cognitive abilities and would have difficulty feeding in the last stages of the condition (National Collaborating Centre for Mental Health, 2007). I have to ensure that the patient receives both spiritual and physical support at this stage. Evidence-based care is crucial in ensuring that patients receive the appropriate intervention. In my role as a nurse, I have to ensure that interventions are acceptable to the patient. I should also consider the preferences of the patient, their past experiences and their own perceptions on how to best manage their condition. Since I would be caring for a patient with declining cognitive abilities, I should ensure that her dignity would be maintained (Baillie and Gallagher, 2011). As part of my future learning development, I will attend courses on how to conduct end-of-life care for patients with dementia. Through Laura, I realised that a patient’s dignity should always be observed. It is recommended that in my future and present practice, I will continue to rely on literature on the best form of interventions of my patient. I will also consult with my colleagues, seek expert opinion and the patient’s experiences on how to choose and deliver interventions. Conclusion Evidence-based practice is important in helping patients achieve quality care. In this case, Laura is an 80-year old patient with dementia. She exhibits the moderate form of the condition but is beginning to show signs of advance dementia. As her nurse, I have the duty to observe ethics in healthcare and to seek for interventions that are evidence-based. However, I also realised that other factors also influence the delivery of interventions. These include socio-political, legal and ethical factors. As a nurse, I have to protect the patient’s rights, act as her advocate and ensure her safety during the trajectory of the condition. For future practice, I will continue to practice evidence-based practice. I will also encourage others in the mental health profession to always consider the patient’s preferences when caring for patients with dementia. When patients are unable to decide for their own care, the carer of the patient could act on her behalf. Finally, as a mental health nurse, I should constantly update myself with the best form of interventions for patients with dementia. This will ensure that my patients will receive evidence-based interventions. References Baillie, L. Gallagher, A.

Justin Bieber - My World free essay sample

On November 17, 2009, Justin Bieber, a 15-year-old discovered on YouTube, came out with his first album. Island Records and the pop star Usher helped young Justin put together â€Å"My World.† Bieber has quickly won over the hearts of many young girls because of his adorable smile and innocent stage presence. The CD is mostly upbeat, happy songs of love for and admiration of a certain girl in the singers life. His most popular song, â€Å"One Time,† is by far the best here and will make listeners sing along. It describes how he felt when he met a girl and how she is now his â€Å"one love.† Another great song is â€Å"Down to Earth,† which displays the artists strength and talent. Although not specifically about love, it conveys the struggles people face, including divorce, and the importance of compromises. The next track, â€Å"Love Me,† is familiar since it is Biebers cover of the song by The Cardigans. We will write a custom essay sample on Justin Bieber My World or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The lyrics have been  ­altered to fit the life of a 15-year-old and have a somewhat techno genre feel. I feel like at my age, 17, I can relate to these songs more than some of the others on the CD. The majority of the songs are easy to become a fan of, but a few are not as catchy or appealing. The lyrics of â€Å"Bigger,† about a young player who has grown up to find love, are  ­confusing and childish, and Biebers voice sounds very high-pitched. â€Å"First Dance†  ­begins with an unknown rapper and then introduces Bieber, who sings about dancing with his date, â€Å"tasting her lip gloss,† and having to be home by nine. This song will only appeal to very young kids, even younger than Justin. Throughout the CD Bieber displays a number of annoying traits, unfortunately: two songs begin with him whispering â€Å"Mafia,† and he refers to himself by his nickname, â€Å"JB,† in every song. The cute and talented Bieber has been very successful in both the United States and his home, Canada. I am glad that we now have a young artist who is truly innocent, and has not (yet) been changed by fame and money. I am a fan of the image he portrays. I look forward to more performances, songs, and success by Bieber.
