They do so by either aggregation or dispersion of melanosomes within the skin. These movements can regulate by means of sympathetic nerves with the help of cytoskeleton. Employing the melanophores on isolated scales of the fingerling of teleost fish, it is attempted to characterise the concerned nerves and the receptors located on melenocytes along with implication of microtubules a part of cytoskeleton in the pigmentary translocation in the fish. The scales from dorso-lateral trunk of the fish represented the sympathetic– neuromelanophore preparations which were stimulated by chemical means, such as adrenergic agonist, antagonist and the microtubule-disrupting drugs such as yuhombine, dopamine, colchicine etc. Adrenaline is an adrenergic agonist which is strongly induced the dorse-dependent concentration of pigment in innervated melanophores while Yohimbine is an adrenergic antagonist which is known to block effectively the α2-adrenoceptors inhibited the action of adrenaline. Colchicine effectively interferes with melanosome aggregating action of adrenaline. From these results it is concluded that the chromatic fibres of adrenergic nature innervate the melanophores and these cells do possess α2-adrenoceptors which mediate the melanosome aggregation and the movements of pigment granules through microtubules means of transport within the cell. These movements of pigment are linked to paling or darkening achieved of teleost fish respectively when they approach to their background. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melenophores" title="melenophores">melenophores</a>, <a href="https://publications.waset.org/abstracts/search?q=agonists" title=" agonists"> agonists</a>, <a href="https://publications.waset.org/abstracts/search?q=antagonist" title=" antagonist"> antagonist</a>, <a href="https://publications.waset.org/abstracts/search?q=colour%20change" title=" colour change"> colour change</a> </p> <a href="https://publications.waset.org/abstracts/161011/colour-change-and-melenophores-response-in-ateleost-balantiochilous-melenopterus-bleeker-with-certain-chemicals-and-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161011.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5166</span> Effect of Diet Inulin Prebiotic on Growth, Reproductive Performance, Carcass Composition and Resistance to Environmental Stresses in Zebra Danio (Danio rerio)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Ahmadifar">Ehsan Ahmadifar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, the effects of different levels (control group (T0), (T1)1, (T2)2 and (T3)3 gr Inulin per Kg diet) of prebiotic Inulin as nutritional supplement on Danio rerio were investigated for 4 month. Since the beginning of feeding larvae until adult (average weight: 67.1 g, length: 4.5 cm) were fed with experimental diets. The survival rate of fish had no significant effect on rate survival (P > 0.05). The highest food conversion ratio (FCR) was in control group and the lowest was observed in T3. Treatment of T3 significantly caused the best feed conversion ratio in Zebra fish (P < 0.05). By increasing the inulin diet during the experiment, specific growth rate increased. The highest and the lowest body weight gain and condition factor were observed in T3 and control, respectively (P < 0.05). Adding 3 gr inulin in Zebra fish diet can improve the performance of the growth indices and final biomass, also this prebiotic can be considered as a suitable supplement for Cyprinidae diet. In the first sampling stage for feeding fish, fat and muscle protein was significantly higher than the second sampling stage (P < 0.05). Given that the second stage fish were full sexual maturity, the amount of fat in muscle decreased (P < 0.05). Moisture and ash levels were significantly (P < 0.05) higher in the second stage sampling than the first stage. Overall, different stage of living affected on muscle chemical composition muscle. Reproductive performance in treatment T2 and T3 were significantly higher than other treatments (P < 0.05). According to the results, the prebiotic inulin does not have a significant impact on the sex ratio in zebrafish (P > 0.05). Based on histology of the gonads, the use of dietary inulin accelerates the process of gonad development in zebrafish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inulin" title="inulin">inulin</a>, <a href="https://publications.waset.org/abstracts/search?q=zebrafish" title=" zebrafish"> zebrafish</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=histology" title=" histology"> histology</a> </p> <a href="https://publications.waset.org/abstracts/62158/effect-of-diet-inulin-prebiotic-on-growth-reproductive-performance-carcass-composition-and-resistance-to-environmental-stresses-in-zebra-danio-danio-rerio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5165</span> Evaluating Accessibility to Bangkok Mass Transit System: Case Study of Saphan Taksin Bangkok Mass Transit System Station</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rungpansa%20Noichan">Rungpansa Noichan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Julian%20Dewancker"> Bart Julian Dewancker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thailand facing the transportation issue because of the rapid economic development. The big issue is the traffic jam, especially in Bangkok. However, recently years Bangkok has operated urban mass transit system for solved transportation problem. The Bangkok Mass Transit System (BTS) skytrain is being operated by the BTS Company Limited under the Bangkok Metropolitan Administration. The passenger satisfaction is a major cause for concern due to the commercial nature. The focus of this paper is to evaluate the passenger satisfaction at the mass transit node by questionnaires survey. The survey was to find out the passenger attitudes. The result shows several important factors that influence the passenger choice of using the BTS as a public transportation mode and the passenger’s opinion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20transportation" title="urban transportation">urban transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20satisfaction" title=" user satisfaction"> user satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=accessibility" title=" accessibility"> accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20mass%20transit" title=" Bangkok mass transit"> Bangkok mass transit</a> </p> <a href="https://publications.waset.org/abstracts/71342/evaluating-accessibility-to-bangkok-mass-transit-system-case-study-of-saphan-taksin-bangkok-mass-transit-system-station" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5164</span> Variation in Maternal Mortality in Sidama National Regional State, Southern Ethiopia: A Population Based Cross Sectional Household Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aschenaki%20Zerihun%20Kea">Aschenaki Zerihun Kea</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernt%20Lindtjorn"> Bernt Lindtjorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Achamyelesh%20Gebretsadik"> Achamyelesh Gebretsadik</a>, <a href="https://publications.waset.org/abstracts/search?q=Sven%20Gudmund%20Hinderaker"> Sven Gudmund Hinderaker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Maternal mortality studies conducted at the national level do not provide the information needed for planning and monitoring health programs at lower administrative levels. The aim of this study was to measure maternal mortality, identify risk factors and district-level variations in Sidama National Regional State, southern Ethiopia. Methods: A cross sectional population-based survey was carried out in households where women reported pregnancy and birth outcomes in the past five years. The study was conducted in the Sidama National Regional State, southern Ethiopia, from July 2019 to May 2020. Multi-stage cluster sampling technique was employed. The outcome variable of the study was maternal mortality. Complex sample logistic regression analysis was applied to assess variables independently associated with maternal mortality. Results: We registered 10602 live births (LB) and 48 maternal deaths, yielding an overall maternal mortality ratio (MMR) of 419; 95% CI: 260-577 per 100,000 LB. Aroresa district had the highest MMR with 1142 (95% CI: 693-1591) per 100,000 LB. Leading causes of death were haemorrhage 21 (41%) and eclampsia 10 (27%). Thirty (59%) mothers died during labour, or within 24 hours after delivery, 25 (47%) died at home and 17 (38%) at a health facility. Mothers who did not have formal education had a higher risk of maternal death (AOR: 4.4; 95% CI: 1.7 – 11.0). The risk of maternal death was higher in districts with a low midwife-to-population ratio (AOR: 2.9; 95% CI: 1.0-8.9). Conclusion: The high maternal mortality with district-level variations in Sidama Region highlights the importance of improving obstetric care and employing targeted interventions in areas with high mortality rates. Due attention should be given to improving access to female education. Additional midwives have to be trained and deployed to improve maternal health services and consequently save the lives of mothers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maternal%20mortality%20variation" title="maternal mortality variation">maternal mortality variation</a>, <a href="https://publications.waset.org/abstracts/search?q=maternal%20death" title=" maternal death"> maternal death</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidama" title=" Sidama"> Sidama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/161980/variation-in-maternal-mortality-in-sidama-national-regional-state-southern-ethiopia-a-population-based-cross-sectional-household-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5163</span> Organic Substance Removal from Pla-Som Family Industrial Wastewater through APCW System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Wararam">W.

The combined system consisted of 50-mm plastic screen, five 5.8 m3 oil-grease trap tanks (2-day hydraulic retention time; HRT), four 4.3 m3 anaerobic tanks (1-day HRT), 16.7 m3 oxidation pond no.1 (7-day HRT), 12.0 m3 oxidation pond no.2 (3-day HRT), and 8.2 m3 constructed wetland plot (1-day HRT). After washing fresh raw fishes, they were sliced in small pieces and were converted into ground fish meat by blender machine. The fish meat was rinsed for 8 rounds: 1, 2, 3, 5, 6 and 7 by tap water and 4 and 8 by rice-wash-water, before mixing with salt, garlic, steamed rice and monosodium glutamate, followed by plastic wrapping for 72-hour of edibility. During pla-som production processing, the rinsed wastewater about 5 m3/day was fed to the treatment systems and fully stagnating storage in its components. The result found that, 1) percentage of treatment efficiency for BOD, COD, TDS and SS were 93, 95, 32 and 98 respectively, 2) the treatment was conducted with 500-kg raw fishes along with full equipment of high organic wastewater treatment systems, 3) the trend of the treatment efficiency and quantity in all indicators was similarly processed and 4) the small pieces of fish meat and fish blood were needed more than 3-day HRT in anaerobic digestion process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20substance" title="organic substance">organic substance</a>, <a href="https://publications.waset.org/abstracts/search?q=Pla-Som%20family%20industry" title=" Pla-Som family industry"> Pla-Som family industry</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=APCW%20system" title=" APCW system"> APCW system</a> </p> <a href="https://publications.waset.org/abstracts/43169/organic-substance-removal-from-pla-som-family-industrial-wastewater-through-apcw-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43169.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5162</span> Studies on the Immunostimulatory Effect of Extract of Solanum Trilobatum and Ocimum Sanctum in Mystus Keletius</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subeena%20Begum">Subeena Begum</a>, <a href="https://publications.waset.org/abstracts/search?q=Navaraj%20Perumalsamy"> Navaraj Perumalsamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The freshwater catfish Mystus keletius was injected with the methanolic extract (water soluble fraction) of Solanum trilobatum and Ocimum sanctum alone and in combination in 3mg, 30mg.300mg/Kg body weight.

Fipronil treatment caused a decrease in body weight gain and increase in relative liver weight. Fipronil induced a significant increase in the liver biomarkers enzymes such as alanine aminotransferases (ALT), aspartate aminotransferases (AST), alkaline phosphatase (ALP) and levels of total protein while fipronil caused a significant decrease in butyryl cholinesterase activity in FPN-treated rats. Oxidative stress biomarkers such as superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST) were significantly decreased in liver tissue, while lipid peroxidation (LPO) was significantly increased in fipronil treating rats in a dose-dependent manner. FPN caused histopathological alterations in liver of female rats. From our results, it can be reported that FPN induced lipid peroxidation, oxidative stress, liver injury in female rats and fish oil used to protect animals against the adverse effect of pesticide exposure. These pathophysiological alterations in liver tissues could be due to the toxic effect of fipronil that associated with a generation of free radicals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fipronil%20%28FPN%29" title="fipronil (FPN)">fipronil (FPN)</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20oil" title="fish oil">fish oil</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatotoxicity" title=" hepatotoxicity"> hepatotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=transaminases" title=" transaminases"> transaminases</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzymes" title=" antioxidant enzymes"> antioxidant enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20rats" title=" female rats"> female rats</a> </p> <a href="https://publications.waset.org/abstracts/102552/protective-role-of-fish-oil-against-hepatotoxicity-induced-by-fipronil-on-female-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102552.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5160</span> Larvicidal Activity of Azadirachtin and Essential Oils from Thymus capitatus against Prays oleae Bern (Lepidoptera, Yponomeutidae) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Blibech">Imen Blibech</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohiedine%20Ksantini"> Mohiedine Ksantini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Bouaziz"> Mohamed Bouaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prays oleae is a major insect of olive in the Mediterranean Region.

The main components of chemical components were oxygenated monoterpenes (60.24%). The most abundant oxygenated monoterpenes were carvacrol (54.11%). Monoterpenes hydrocarbons were much more abundant and dominated by the o-cymene (16.68%). Both active compounds of Azadirachtin and Thymus capitatus oil extracts exhibited significant larvicidal activity against P. oleae with LC50 values 81.30 ppm and 52.49 ppm respectively. Dose-response relationships were established with almost 100% mortality when using the highest dose 100 ppm of T. capitatus oil extracts and 80 ppm of Azadirachtin. At the lowest dose (10 ppm), T. capitatus oil extracts and Azadirachtin caused 60% and 76% larval mortality in 48 hours respectively. The larval mortality rate greatly decreased with increases of the dilution of both oil extract compounds. Larval development duration appeared to be prolonged to about 12 days for larvae feeding on control diet. The maximum antifeedant activity was shown by both T. capitatus oil extract and Azadirachtin at LC90 values (47.5 and 50.1 ppm respectively). Tunisian T. capitatus oil extract used at low concentrations could be considered as eco-friendly promising insecticide similar to Azadirachtin that has significant potential for the biological control of P. oleae. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thymus%20capitatus" title="Thymus capitatus">Thymus capitatus</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title=" chemical composition"> chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=azadirachtin" title=" azadirachtin"> azadirachtin</a>, <a href="https://publications.waset.org/abstracts/search?q=larvicidal%20effects" title=" larvicidal effects"> larvicidal effects</a>, <a href="https://publications.waset.org/abstracts/search?q=antifeedant%20activity" title=" antifeedant activity"> antifeedant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Prays%20oleae" title=" Prays oleae"> Prays oleae</a> </p> <a href="https://publications.waset.org/abstracts/66890/larvicidal-activity-of-azadirachtin-and-essential-oils-from-thymus-capitatus-against-prays-oleae-bern-lepidoptera-yponomeutidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5159</span> Environmental, Climate Change, and Health Outcomes in the World</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felix%20Aberu">Felix Aberu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high rate of greenhouse gas (CO₂) emission and increased concentration of Carbon Dioxide in the atmosphere are not unconnected to both human and natural activities. This has caused climate change and global warming in the world. The adverse effect of these climatic changes has no doubt threatened human existence. Hence, this study examined the effects of environmental and climate influence on mortality and morbidity rates, with particular reference to the world’s leading CO₂ emission countries, using both the pre-estimation, estimation, and post-estimation techniques for more dependable outcomes. Hence, the System Generalized Method of Moments (SGMM) was adopted as the main estimation technique for the data analysis from 1996 to 2023. The coefficient of carbon emissions confirmed a positive and significant relationship among CO₂ emission, mortality, and morbidity rates in the world’s leading CO₂ emissions countries, which implies that carbon emission has contributed to mortality and morbidity rates in the world. Therefore, significant action should be taken to facilitate the expansion of environmental protection and sustainability initiatives in any CO₂ emissions nations of the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental" title="environmental">environmental</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=morbidity" title=" morbidity"> morbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20outcomes" title=" health outcomes"> health outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20emissions" title=" carbon emissions"> carbon emissions</a> </p> <a href="https://publications.waset.org/abstracts/184613/environmental-climate-change-and-health-outcomes-in-the-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184613.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">54</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5158</span> Cloning and Analysis of Nile Tilapia Toll-like receptors Type-3 mRNA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelazeem%20Algammal">Abdelazeem Algammal</a>, <a href="https://publications.waset.org/abstracts/search?q=Reham%20Abouelmaatti"> Reham Abouelmaatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaokun%20Li"> Xiaokun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Jisheng%20Ma"> Jisheng Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Abdelnaby"> Eman Abdelnaby</a>, <a href="https://publications.waset.org/abstracts/search?q=Wael%20Elfeil"> Wael Elfeil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Toll-like receptors (TLRs) are the best understood of the innate immune receptors that detect infections in vertebrates. However, the fish TLRs also exhibit very distinct features and a large diversity, which is likely derived from their diverse evolutionary history and the distinct environments that they occupy. Little is known about the fish immune system structure. Our work was aimed to identify and clone the Nile tilapiaTLR-3 as a model of freshwater fish species; we cloned the full-length cDNA sequence of Nile tilapia (Oreochromis niloticus) TLR-3 and according to our knowledge, it is the first report illustrating tilapia TLR-3. The complete cDNA sequence of Nile tilapia TLR-3 was 2736 pair base and it encodes a polypeptide of 912 amino acids. Analysis of the deduced amino acid sequence indicated that Nile tilapia TLR-3 has typical structural features and main components of proteins belonging to the TLR family. Our results illustrate a complete and functional Nile tilapia TLR-3 and it is considered an ortholog of the other vertebrate’s receptor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nile%20tilapia" title="Nile tilapia">Nile tilapia</a>, <a href="https://publications.waset.org/abstracts/search?q=TLR-3" title=" TLR-3"> TLR-3</a>, <a href="https://publications.waset.org/abstracts/search?q=cloning" title=" cloning"> cloning</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a> </p> <a href="https://publications.waset.org/abstracts/123307/cloning-and-analysis-of-nile-tilapia-toll-like-receptors-type-3-mrna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123307.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5157</span> Lamellodiscus spp. (Monogenoidea: Diplectanidae) Infecting the Gill Lamellae of Porgies (Spariformes: Sparidae) in Dakar Coast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sikhou%20Drame">Sikhou Drame</a>, <a href="https://publications.waset.org/abstracts/search?q=Arfang%20Diamanka"> Arfang Diamanka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Senegal, the fishing sector plays an important role in socio-economic development. However, he is going through enormous difficulties, caused by the scarcity of fish on the Senegalese coast, the overexploitation of fishery resources. Based on this observation, the authorities are betting on the development of aquaculture. It is in this context that the exploration of fish from the highly consumed Sparidae family remains a good solution. Indeed, the Sparidae family has good characteristics for farming at sea. However, parasites can proliferate and destroy the efforts made to cultivate fish in confined areas. the knowledge of these parasites in particular the monogeneans, very specific to the sparidae fishes will allow to better know the bio-ecology of the fishes. Better know the main parasitic monogeneans of the genus Lamellodiscus of sparidae fish of the genus Pagrus harvested in Senegal. It will first be a question of identifying from the observation of the morpho-anatomical characters, Monogeneans of the genus Lamellodiscus, branchial parasites collected from three species of host: Pagrus caeruleostictus , Pagrus auriga and Pagrus africanus. Then to evaluate the spatial and temporary distribution of parasitic indices on two Dakar landing sites (Soumbédioune and Yarakh) and finally to determine their specificity. The fish examined were purchased directly from the landing sites in Dakar and then transported to the laboratory where they were identified, then dissected. The gills were examined under a magnifying glass and the monogeneans were harvested, fixed in 70% ethanol and then mounted between slide and coverslip. The identification of the parasites is based on the observation of the morpho-anatomical characters and on the measurements of the sclerified organs of the haptor and the male copulatory organ. In total out of the 90 individuals examined: Pagrus auriga (30), Pagrus africanus (30) and Pagrus caeruleostictus (30), 6 species of monogeneans of the genus Lamellodiscus (Monogenea, Diplectanidae) are obtained: L. sarculus, L. sigillatus, L.vicinus, L. rastellus, L. africanus n.sp and L. yarakhensis n.sp. Our results show that specimens of small sizes [15-20[cm are the most infested. The values of infestation intensity and abundance are higher in fish from Yarakh and also during the cold season. it is the species Pagrus caeruleostictus which records the highest parasitic loads in the two localities. the majority of the parasites identified have a strict or oioxene specificity. It appears from this study that fish of the genus Pagrus are highly parasitized by monogeneans of the genus Lamellodiscus with a general prevalence of 87.78%. Each infested fish has an average of 30 monogeneans of the genus Lamellodiscus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monogeneans" title="monogeneans">monogeneans</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamellodiscus" title=" Lamellodiscus"> Lamellodiscus</a>, <a href="https://publications.waset.org/abstracts/search?q=Dakar%20coast" title=" Dakar coast"> Dakar coast</a>, <a href="https://publications.waset.org/abstracts/search?q=genus%20Pagrus" title=" genus Pagrus"> genus Pagrus</a> </p> <a href="https://publications.waset.org/abstracts/166355/lamellodiscus-spp-monogenoidea-diplectanidae-infecting-the-gill-lamellae-of-porgies-spariformes-sparidae-in-dakar-coast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5156</span> Triploid Rainbow Trout (Oncorhynchus mykiss) for Better Aquaculture and Ecological Risk Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20N.%20Pandey">N.

Rainbow trout farming has a great potential for its contribution to the mainstream economy of Himalayan states in India and other temperate countries. These characteristics establish them as one of the most widely introduced and cultured fish across the globe, and its farming is also prominent in the cold water regions of India. Nevertheless, genetic fatigue, slow growth, early maturity, and low productivity are limiting the expansion of trout production. Moreover, farms adjacent to natural streams or other water sources are subject to escape of domesticated rainbow trout into the wild, which is a serious environmental concern as the escaped fish is subject to contaminate and disrupt the receiving ecosystem. A decline in production traits due to early maturity prolongs the culture duration and affects the profit margin of rainbow trout farms in India. A viable strategy that could overcome these farming constraints in large scale operation is the production of triploid fish that are sterile and more heterozygous. For better triploidy induction rate (TR), heat shock at 28°C for 10 minutes and pressure shock 9500 psi pressure for 5 minutes is applied to green eggs with 90-100% of triploidy success and 72-80% survival upto swim-up fry stage. There is 20% better growth in aquaculture with triploids rainbow trout over diploids. As compared to wild diploid fish, larger sized and fitter triploid rainbow trout in natural waters attract to trout anglers, and support the development of recreational fisheries by state fisheries departments without the risk of contaminating existing gene pools and disrupting local fish diversity. Overall, enhancement of productivity in rainbow trout farms and trout production in coldwater regions, development of lucrative trout angling and better ecological management is feasible with triploid rainbow trout. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rainbow%20trout" title="rainbow trout">rainbow trout</a>, <a href="https://publications.waset.org/abstracts/search?q=triploids%20fish" title=" triploids fish"> triploids fish</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20shock" title=" heat shock"> heat shock</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20shock" title=" pressure shock"> pressure shock</a>, <a href="https://publications.waset.org/abstracts/search?q=trout%20angling" title=" trout angling"> trout angling</a> </p> <a href="https://publications.waset.org/abstracts/108397/triploid-rainbow-trout-oncorhynchus-mykiss-for-better-aquaculture-and-ecological-risk-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108397.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5155</span> Substitution of Fish Meal by Local Vegetable Raw Materials in the Feed of Juvenile Nile Tilapia (Oreochromis Niloticus, Linne, 1758) in Senegal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mamadou%20Sileye%20Niang">Mamadou Sileye Niang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study is a contribution to the development of a feed for juvenile tilapia Oreochromis niloticus, from local raw materials in order to reduce the cost of feeding farmed tilapia in Senegal. Three feeds were formulated from local raw materials. The basic composition of the tested feeds is as follows: A1 (peanut meal, rice bran, millet bran, maize meal and no fish meal); A2 (peanut meal, rice bran, millet bran, maize meal and 10% fish meal) and A3 (peanut meal, rice bran, millet bran, maize meal and 25% fish meal). All feeds contain 31% protein. The trial compared three batches, in 2 replicates, with different diets. The initial weight of the juveniles was 0.37± 0.5g. The daily ration was distributed at 9 am and 4 pm. After 90 days of the experiment, the final mean weights were 2.45 ± 0.5g; 2.75±0.5g; and 4.67 ± 0.5g for A1, A2, and A3, respectively. A performance test, of which the objective was to compare growth parameters, was conducted. The results of the growth parameters of juveniles fed A3 were significantly higher (p < 0.05) than those fed A1 and A2. The weight growth study shows similar growth during the first month. However, from this date onwards, juveniles fed A3 show a faster growth, which is maintained throughout the experiment. On the other hand, the Protein Efficiency Coefficient and the Survival Rate showed no significant difference. The zootechnical parameters are not significantly different (p > 0.05) between the two tanks for the same feed treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrition" title="nutrition">nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=feed" title=" feed"> feed</a>, <a href="https://publications.waset.org/abstracts/search?q=fingerlings" title=" fingerlings"> fingerlings</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis" title=" Oreochromis"> Oreochromis</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20raw%20materials" title=" local raw materials"> local raw materials</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20cost" title=" feed cost"> feed cost</a> </p> <a href="https://publications.waset.org/abstracts/162920/substitution-of-fish-meal-by-local-vegetable-raw-materials-in-the-feed-of-juvenile-nile-tilapia-oreochromis-niloticus-linne-1758-in-senegal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162920.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5154</span> Effect of Ginger (Zingiber Officinale) And Garlic (Allium Sativum) Mixture on Growth Performance, Feed Utilization and Survival of Clarias Gariepinus Fingerlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20I.%20Abdullahi">Maryam I.

The present study aimed to determine a simple, easy, reliable anthropometric measure(s) that can predict LBW) and neonatal mortality. Methods: A prospective cohort study of 570 babies born in districts of El Menia governorate, Egypt (where most deliveries occurred at home) was examined at birth. Newborn weight, length, head, chest, mid-arm, and thigh circumferences were measured. Follow up of the examined neonates took place during their first four weeks of life to report any mortalities. The most predictable anthropometric measures were determined using the statistical package of SPSS, and multiple Logistic regression analysis was performed.: Results: Head and chest circumferences with cut-off points < 33 cm and ≤ 31.5 cm, respectively, were the significant predictors for LBW. They carried the best combination of having the highest sensitivity (89.8 % & 86.4 %) and least false negative predictive value (1.4 % & 1.7 %). Chest circumference with a cut-off point ≤ 31.5 cm was the significant predictor for neonatal mortality with 83.3 % sensitivity and 0.43 % false negative predictive value. Conclusion: Using chest circumference with a cut-off point ≤ 31.5 cm is recommended as a single simple anthropometric measurement for the prediction of both LBW and neonatal mortality. The predicted measure could act as a substitute for weighting newborns in communities where scales to weigh them are not routinely available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20birth%20weight" title="low birth weight">low birth weight</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal%20mortality" title=" neonatal mortality"> neonatal mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropometric%20measures" title=" anthropometric measures"> anthropometric measures</a>, <a href="https://publications.waset.org/abstracts/search?q=practical%20screening" title=" practical screening"> practical screening</a> </p> <a href="https://publications.waset.org/abstracts/162775/development-of-a-practical-screening-measure-for-the-prediction-of-low-birth-weight-and-neonatal-mortality-in-upper-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162775.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5152</span> Application of Stochastic Models on the Portuguese Population and Distortion to Workers Compensation Pensioners Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nkwenti%20Mbelli%20Njah">Nkwenti Mbelli Njah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research was motivated by a project requested by AXA on the topic of pensions payable under the workers compensation (WC) line of business. There are two types of pensions: the compulsorily recoverable and the not compulsorily recoverable. A pension is compulsorily recoverable for a victim when there is less than 30% of disability and the pension amount per year is less than six times the minimal national salary. The law defines that the mathematical provisions for compulsory recoverable pensions must be calculated by applying the following bases: mortality table TD88/90 and rate of interest 5.25% (maybe with rate of management). To manage pensions which are not compulsorily recoverable is a more complex task because technical bases are not defined by law and much more complex computations are required. In particular, companies have to predict the amount of payments discounted reflecting the mortality effect for all pensioners (this task is monitored monthly in AXA). The purpose of this research was thus to develop a stochastic model for the future mortality of the worker’s compensation pensioners of both the Portuguese market workers and AXA portfolio. Not only is past mortality modeled, also projections about future mortality are made for the general population of Portugal as well as for the two portfolios mentioned earlier. The global model was split in two parts: a stochastic model for population mortality which allows for forecasts, combined with a point estimate from a portfolio mortality model obtained through three different relational models (Cox Proportional, Brass Linear and Workgroup PLT). The one-year death probabilities for ages 0-110 for the period 2013-2113 are obtained for the general population and the portfolios. These probabilities are used to compute different life table functions as well as the not compulsorily recoverable reserves for each of the models required for the pensioners, their spouses and children under 21. The results obtained are compared with the not compulsory recoverable reserves computed using the static mortality table (TD 73/77) that is currently being used by AXA, to see the impact on this reserve if AXA adopted the dynamic tables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compulsorily%20recoverable" title="compulsorily recoverable">compulsorily recoverable</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20table%20functions" title=" life table functions"> life table functions</a>, <a href="https://publications.waset.org/abstracts/search?q=relational%20models" title=" relational models"> relational models</a>, <a href="https://publications.waset.org/abstracts/search?q=worker%E2%80%99s%20compensation%20pensioners" title=" worker’s compensation pensioners"> worker’s compensation pensioners</a> </p> <a href="https://publications.waset.org/abstracts/75580/application-of-stochastic-models-on-the-portuguese-population-and-distortion-to-workers-compensation-pensioners-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5151</span> Effect of Different Commercial Diets and Temperature on the Growth Performance, Feed Intake and Feed Conversion Ratio of Sobaity Seabream Sparidentex hasta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seemab%20Zehra">Seemab Zehra</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20W.%20Mohammed"> A.

In experiment I, growth performance, feed intake, protein efficiency ratio (PER), feed conversion ratio (FCR) and survival (%) of sobaity seabream Sparidentex hasta (330.5±2.6 g; 26.9±1.0 cm) were evaluated by four different commercial diets (1, 2, 3 and 4) for 80 days. The daily weight gain was around 3.2 g day-1 with an SGR of 0.7% day-1. Both the FCR and PER in the fish were significantly better in diet 2 that contained 46.36% crude protein and 12.54% crude fat. In experiment II, (99±2.6 g; 17.1±1.0 cm). The fish were cultured in 1m3 tanks supplied with seawater from the Red Sea wherein three different rearing temperatures were set as treatments (24, 28 and 32°C). Fish were fed with a commercial diet based on the results of experiment I (46.4% protein; 20.1 MJ kg-1 energy) to satiation for 96 days. Total weight gain was significantly higher for the fish reared in the 32°C group (158.57 g) followed by the 28°C group (138.25 g), while the lowest weight gain was observed in the 24°C group (116.98 g). The FCR was significantly lower in the 32°C group (1.62) as compared to 28 (1.8) and 24°C (1.85) groups. Based on the results obtained from these preliminary studies (experiment I and II), sobaity seabream can attain better growth performance, FCR and PER at 32°C in the Red Sea by feeding commercial diet 2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sparidentex%20hasta" title="Sparidentex hasta">Sparidentex hasta</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=FCR" title=" FCR"> FCR</a>, <a href="https://publications.waset.org/abstracts/search?q=Red%20Sea" title=" Red Sea"> Red Sea</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performance" title=" growth performance"> growth performance</a> </p> <a href="https://publications.waset.org/abstracts/168221/effect-of-different-commercial-diets-and-temperature-on-the-growth-performance-feed-intake-and-feed-conversion-ratio-of-sobaity-seabream-sparidentex-hasta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168221.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5150</span> Nutritive Advantage of Mealworm (Tenebrio molitor) in the Diet of White Shrimp (Litopenaeus vannamei)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae-ho%20Chung">Tae-ho Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul%20Park"> Chul Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Gi-wook%20Shin"> Gi-wook Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Joo-min%20Kim"> Joo-min Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-hyun%20Kim"> Seong-hyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Namjung%20Kim"> Namjung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mealworm (Tenebrio molitor) was evaluated to investigate the effect of partial or total replacement of fish meal in diets for white shrimp, Litopenaeus vannamei.

Our aim was to assessed the environmental drivers importance in regulating species richness and community structure of fish species. The lchthyofauna assemblage of Warri River, Niger Delta area of Nigeria was studied between August 2013 and July 2014. A total of 1152 individuals representing 43 species in 23 families and 30 genera were caught. Of the 43 species recorded, 67.4%, 53.5% and 67.4% of the species occurred in Stations 1, 2 and 3 respectively. Eight taxa representing 18.6% of the total abundance were ubiquitous. The claroteid, Chrysichthys walkeri and the cichlid, Chromidotilapia guentheri were the most dominant species accounting for 19.2% and 6.0% respectively of the total catch. The species richness and general diversity were relatively higher in station 1 although Jaccard similarity index revealed that stations 1 and 3 were significantly similar while station 2 showed complete dissimilarity with stations 1 and 3. Canonical correspondence analysis indicated that dissolved oxygen, electrical conductivity, total nitrogen, Biochemical Oxygen demand and temperature were important variables structuring the overall fish assemblages. The presence of appreciable number of juveniles in this water body suggests that the Warri River is a breeding and nursery ground for fish species particularly those of brackish origin. These findings indicate that the water body is still useful as a good fishing ground for the rural communities and every effort should be put in place to ensure its protection and conservation for the production of healthy fish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chrysichthys%20walkeri" title="Chrysichthys walkeri">Chrysichthys walkeri</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20communities" title=" fish communities"> fish communities</a>, <a href="https://publications.waset.org/abstracts/search?q=mangrove%20ecosystem" title=" mangrove ecosystem"> mangrove ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20parameters" title=" physicochemical parameters"> physicochemical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=Warri%20River" title=" Warri River"> Warri River</a> </p> <a href="https://publications.waset.org/abstracts/26899/environmental-drivers-of-ichthyofauna-species-diversity-and-richness-in-the-lower-reaches-of-warri-river-a-typical-mangrove-ecosystem-in-the-niger-delta-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26899.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5148</span> Demographic Characteristics and Factors Affecting Mortality in Pediatric Trauma Patients Who Are Admitted to Emergency Service</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latif%20Duran">Latif Duran</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdem%20Aydin"> Erdem Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Baydin"> Ahmet Baydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kemal%20Erenler"> Ali Kemal Erenler</a>, <a href="https://publications.waset.org/abstracts/search?q=Iskender%20Aksoy"> Iskender Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: In this retrospective study, we aim to contribute to the literature by presenting the proposals for taking measures to reduce the mortality by examining the demographic characteristics of the pediatric age group patients presenting with trauma and the factors that may cause mortality Material and Method: This study has been performed by retrospectively investigating the data obtained from the patient files and the hospital automation registration system of the pediatric trauma patients who applied to the Adult Emergency Department of the Ondokuz Mayıs University Medical Faculty between January 1, 2016, and December 31, 2016. Results: 289 of 415 patients involved in our study, were males. The median age was 11.3 years. The most common trauma mechanism was falling from the high. A significant statistical difference was found on the association between trauma mechanisms and gender. An increase in the number of trauma cases was found especially in the summer months. The study showed that thoracic and abdominal trauma was relevant to the increased mortality. Computerized tomography was the most common diagnostic imaging modality. The presence of subarachnoid hemorrhage has increased the risk of mortality by 62.3 fold. Eight of the patients (1.9%) died. Scoring systems were statistically significant to predict mortality. Conclusion: Children are vulnerable to trauma because of their unique anatomical and physiological differences compared to adult patient groups. It will be more successful in the mortality rate and in the post-traumatic healing process by administering the patient triage fast and most appropriate trauma centers in the prehospital period, management of the critical patients with the scoring systems and management with standard treatment protocols <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency%20service" title="emergency service">emergency service</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20patients" title=" pediatric patients"> pediatric patients</a>, <a href="https://publications.waset.org/abstracts/search?q=scoring%20systems" title=" scoring systems"> scoring systems</a>, <a href="https://publications.waset.org/abstracts/search?q=trauma" title=" trauma"> trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=age%20groups" title=" age groups"> age groups</a> </p> <a href="https://publications.waset.org/abstracts/91446/demographic-characteristics-and-factors-affecting-mortality-in-pediatric-trauma-patients-who-are-admitted-to-emergency-service" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5147</span> Supplementation of Mannan Oligosaccharides in Guinea Pigs: Mortality and Growth Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Minguez">C.

In this research, the effect of MOS dietary supplementation on growth performance and mortality in meat guinea pigs were studied. Three different experimental groups were compared: Control group (no additives); MOS 1 (1.5 g kg−1); MOS 2 (2 g kg−1). Guinea pigs were housed in 15 collective cages (n = 50 animals in each trial; 10 animals per cage). The young guinea pigs were weaning at day 28 and individually identified by a little ear tag. The fattening period was 49 days. Guinea pigs in both groups were fed ad libitum, with a standard commercial pellet diet (10 MJ of digestible energy/kg, 17% crude protein, 11% crude fiber, and 4.5% crude fat) and alfalfa (Medicago sativa) as forage. Growth traits, including body weight (BW), average daily gain (ADG), feed intake (FI), and feed conversion ratio (FCR), were measured weekly. On day 74, the animals were slaughtered. Contrasts between groups were obtained by calculated generalized least squares values. Mortality were evaluated by Fisher's exact test. Between MOS groups no significant differences were observed for growth traits and mortality. However, significant differences against the control group were observed for traits studied (pvalue < 0.05). In conclusion, the use of MOS could be a good prebiotic supplement to raise guinea pigs because it MOS has shown positive effects in growth traits and immune response in animals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=guinea%20pig" title="guinea pig">guinea pig</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=mannan%20oligosaccharides" title=" mannan oligosaccharides"> mannan oligosaccharides</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/98416/supplementation-of-mannan-oligosaccharides-in-guinea-pigs-mortality-and-growth-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98416.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5146</span> Probabilistic Approach to the Spatial Identification of the Environmental Sources behind Mortality Rates in Europe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alina%20Svechkina">Alina Svechkina</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20A.%20Portnov"> Boris A.

In the present study, we discuss a probabilistic approach to the spatial identification of a priori unidentified environmental health hazards. The underlying assumption behind the tested approach is that the observed adverse health patterns (morbidity, mortality) can become a source of information on the geographic location of environmental risk factors that stand behind them. Using this approach, we analyzed sources of environmental exposure using data on mortality rates available for the year 2015 for NUTS 3 (Nomenclature of Territorial Units for Statistics) subdivisions of the European Union. We identified several areas in the southwestern part of Europe as primary risk sources for the observed mortality patterns. Multivariate regressions, controlled by geographical location, climate conditions, GDP (gross domestic product) per capita, dependency ratios, population density, and the level of road freight revealed that mortality rates decline as a function of distance from the identified hazard location. We recommend the proposed approach an exploratory analysis tool for initial investigation of regional patterns of population morbidity patterns and factors behind it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mortality" title="mortality">mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20hazards" title=" environmental hazards"> environmental hazards</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20pollution" title=" air pollution"> air pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20decay%20gradient" title=" distance decay gradient"> distance decay gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20regression%20analysis" title=" multi regression analysis"> multi regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Europe" title=" Europe"> Europe</a>, <a href="https://publications.waset.org/abstracts/search?q=NUTS3" title=" NUTS3"> NUTS3</a> </p> <a href="https://publications.waset.org/abstracts/89170/probabilistic-approach-to-the-spatial-identification-of-the-environmental-sources-behind-mortality-rates-in-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5145</span> Efficacy of Microwave against Oryzaephilus Mercator Pest Infesting Dried Figs and Evaluation of the Product Color Changes Using an Image Processing Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Sadeghi">Reza Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, microwave heating was employed for controlling Oryzaephilus mercator. adults infesting stored Iranian dried fig. For this purpose, the dried fig samples were artificially infested with O. mercator and then heated in a microwave oven (2450 MHz) at the power outputs of 450, 720, and 900 W for 10, 20, 30, and 40 s, respectively. Subsequently, changes in the colors of the product samples under the effects of the varied microwave applications were investigated in terms of lightness (ΔL*), redness (Δa*), and yellowness (Δb*) using an image processing technique. The results revealed that both parameters of microwave power and exposure time had significant impacts on the pest mortality rates (p<0.01). In fact, a direct positive relationship was obtained between the mortality rate and microwave irradiation power. Complete mortality was achieved for the pest at the power of 900 W and exposure time of 40 s. The dried fig samples experienced fewer changes in their color parameters. Considering the successful pest control and acceptable changes in the product quality, microwave irradiation can be introduced as an appropriate alternative to chemical fumigants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colorimetric%20assay" title="colorimetric assay">colorimetric assay</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20heating" title=" microwave heating"> microwave heating</a>, <a href="https://publications.waset.org/abstracts/search?q=Oryzaephilus%20mercator" title=" Oryzaephilus mercator"> Oryzaephilus mercator</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/170388/efficacy-of-microwave-against-oryzaephilus-mercator-pest-infesting-dried-figs-and-evaluation-of-the-product-color-changes-using-an-image-processing-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170388.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5144</span> Effect of Atrial Flutter on Alcoholic Cardiomyopathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Ahmed">Ibrahim Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Amoateng"> Richard Amoateng</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhil%20Jain"> Akhil Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ahmed"> Mohamed Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alcoholic cardiomyopathy (ACM) is a type of acquired cardiomyopathy caused by chronic alcohol consumption. Frequently ACM is associated with arrhythmias such as atrial flutter. Our aim was to characterize the patient demographics and investigate the effect of atrial flutter (AF) on ACM. This was a retrospective cohort study using the Nationwide Inpatient Sample database to identify admissions in adults with principal and secondary diagnoses of alcoholic cardiomyopathy and atrial flutter from 2019. Multivariate linear and logistic regression models were adjusted for age, gender, race, household income, insurance status, Elixhauser comorbidity score, hospital location, bed size, and teaching status. The primary outcome was all-cause mortality, and secondary outcomes were the length of stay (LOS) and total charge in USD. There was a total of 21,855 admissions with alcoholic cardiomyopathy, of which 1,635 had atrial flutter (AF-ACM). Compared to Non-AF-ACM cohort, AF-ACM cohort had fewer females (4.89% vs 14.54%, p<0.001), were older (58.66 vs 56.13 years, p<0.001), fewer Native Americans (0.61% vs2.67%, p<0.01), had fewer smaller (19.27% vs 22.45%, p<0.01) & medium-sized hospitals (23.24% vs28.98%, p<0.01), but more large-sized hospitals (57.49% vs 48.57%, p<0.01), more Medicare (40.37% vs 34.08%, p<0.05) and fewer Medicaid insured (23.55% vs 33.70%, p=<0.001), fewer hypertension (10.7% vs 15.01%, p<0.05), and more obesity (24.77% vs 16.35%, p<0.001). Compared to Non-AF-ACM cohort, there was no difference in AF-ACM cohort mortality rate (6.13% vs 4.20%, p=0.0998), unadjusted mortality OR 1.49 (95% CI 0.92-2.40, p=0.102), adjusted mortality OR 1.36 (95% CI 0.83-2.24, p=0.221), but there was a difference in LOS 1.23 days (95% CI 0.34-2.13, p<0.01), total charge $28,860.30 (95% CI 11,883.96-45,836.60, p<0.01). In patients admitted with ACM, the presence of AF was not associated with a higher all-cause mortality rate or odds of all-cause mortality; however, it was associated with 1.23 days increase in LOS and a $28,860.30 increase in total hospitalization charge. Native Americans, older age and obesity were risk factors for the presence of AF in ACM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alcoholic%20cardiomyopathy" title="alcoholic cardiomyopathy">alcoholic cardiomyopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=atrial%20flutter" title=" atrial flutter"> atrial flutter</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiomyopathy" title=" cardiomyopathy"> cardiomyopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=arrhythmia" title=" arrhythmia"> arrhythmia</a> </p> <a href="https://publications.waset.org/abstracts/149617/effect-of-atrial-flutter-on-alcoholic-cardiomyopathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149617.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5143</span> Gravitationally Confined Relativistic Neutrinos and Mathematical Modeling of the Structure of Pions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Constantinos%20Vayenas">Constantinos Vayenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Athanasios%20Fokas"> Athanasios Fokas</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Grigoriou"> Dimitrios Grigoriou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We use special relativity to compute the inertial and thus gravitational mass of relativistic electron and muon neutrinos, and we find that, for neutrino kinetic energies above 150 MeV/c2, these masses are in the Planck mass range.

Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Characterization of diverse microbial communities in specific environment plays a crucial role in the better understanding of their functional relationship with the ecosystem. It is now well established that gut microbiome of fish is not the simple replication of microbiota of surrounding local habitat, and extensive species, dietary, physiological and metabolic variations in fishes may have a significant impact on its composition. Moreover, overuse of antibiotics in human, veterinary and aquaculture medicine has led to rapid emergence and propagation of antibiotic resistance genes (ARGs) in the aquatic environment. Microbial communities harboring specific ARGs not only get a preferential edge during selective antibiotic exposure but also possess the significant risk of ARGs transfer to other non-resistance bacteria within the confined environments. This phenomenon may lead to the emergence of habitat-specific microbial resistomes and subsequent emergence of virulent antibiotic-resistant pathogens with severe fish and consumer health consequences. In this study, gut microbiota of freshwater carp (Labeo rohita) was investigated by shotgun metagenomics to understand its taxonomic composition and functional capabilities. Metagenomic DNA, extracted from the fish gut, was subjected to sequencing on Illumina NextSeq to generate paired-end (PE) 2 x 150 bp sequencing reads. After the QC of raw sequencing data by Trimmomatic, taxonomic analysis by Kraken2 taxonomic sequence classification system revealed the presence of 36 phyla, 326 families and 985 genera in the fish gut microbiome. At phylum level, Proteobacteria accounted for more than three-fourths of total bacterial populations followed by Actinobacteria (14%) and Cyanobacteria (3%). Commonly used probiotic bacteria (Bacillus, Lactobacillus, Streptococcus, and Lactococcus) were found to be very less prevalent in fish gut. After sequencing data assembly by MEGAHIT v1.1.2 assembler and PROKKA automated analysis pipeline, pathway analysis revealed the presence of 1,608 Metacyc pathways in the fish gut microbiome. Biosynthesis pathways were found to be the most dominant (51%) followed by degradation (39%), energy-metabolism (4%) and fermentation (2%). Almost one-third (33%) of biosynthesis pathways were involved in the synthesis of secondary metabolites. Metabolic pathways for the biosynthesis of 35 antibiotic types were also present, and these accounted for 5% of overall metabolic pathways in the fish gut microbiome. Fifty-one different types of antibiotic resistance genes (ARGs) belonging to 15 antimicrobial resistance (AMR) gene families and conferring resistance against 24 antibiotic types were detected in fish gut. More than 90% ARGs in fish gut microbiome were against beta-lactams (penicillins, cephalosporins, penems, and monobactams). Resistance against tetracycline, macrolides, fluoroquinolones, and phenicols ranged from 0.7% to 1.3%. Some of the ARGs for multi-drug resistance were also found to be located on sequences of plasmid origin. The presence of pathogenic bacteria and ARGs on plasmid sequences suggested the potential risk due to horizontal gene transfer in the confined gut environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title="antibiotic resistance">antibiotic resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20gut" title=" fish gut"> fish gut</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20pathways" title=" metabolic pathways"> metabolic pathways</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20diversity" title=" microbial diversity"> microbial diversity</a> </p> <a href="https://publications.waset.org/abstracts/99462/analysis-of-taxonomic-compositions-metabolic-pathways-and-antibiotic-resistance-genes-in-fish-gut-microbiome-by-shotgun-metagenomics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99462.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5141</span> Challenges of Sustainable Marine Fishing in Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20K.%20W.%20Aikins">Eric K. W. Aikins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditionally, Ghana is a marine fishing country. The fishing industry dominated by artisanal marine fishing helps Ghana to meet its fish and protein requirements. Also, it provides employment for most coastal dwellers that depend on fishing as their main economic enterprise. Nonetheless, the marine fishing industry is confronted with challenges that have contributed to a declining fish production in recent past decade. Bad fishing practices and the general limited knowledge on sustainable management of fisheries resources are the limiting factors that affect sustainable fish production and sustainable marine biodiversity management in Ghana. This paper discusses the challenges and strategies for attaining and maintaining sustainable marine fishing in Ghana as well as the state of marine fishing in Ghana. It concludes that an increase in the level of involvement of local fishers in the management of fisheries resources of the country could help local fishers to employ sustainable fisheries resources exploitation methods that could result in an improvement in the spatio-economic development and wellbeing of affected fishing communities in particular and Ghana in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pair%20trawling" title="pair trawling">pair trawling</a>, <a href="https://publications.waset.org/abstracts/search?q=sargassum" title=" sargassum"> sargassum</a>, <a href="https://publications.waset.org/abstracts/search?q=spatio-economic%20development" title=" spatio-economic development"> spatio-economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20marine%20fishing" title=" sustainable marine fishing"> sustainable marine fishing</a> </p> <a href="https://publications.waset.org/abstracts/86329/challenges-of-sustainable-marine-fishing-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5140</span> The Influence of the Aquatic Environment on Hematological Parameters in Cyprinus carpio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andreea%20D.%20%C8%98erban">Andreea D.

Thus, going beyond the ideal environment, in which all water quality parameters are permanently in perfect standards for reproduction, growth, and development of fish material and customizing this study to reality, it was demonstrated the importance of reproduction, development, and growth of biological material, necessary in the population fish farms, in the same environment to gain the maximum yield that a fish farm can offer. The biological material used was harvested from 3 fish farms located at great distances from each other to have environments with different parameters. The specimens were clinically healthy at 2 years of age. Thus, the differences in water quality parameters had effects on specimens from other environments, describing large curves in their evolution in new environments. Another change was observed in the new environment, the specimens contributing with the "genetic package" to its modification, tending to a balance of the parameters studied to the values in the environment in which they lived until the time of the experiment. The study clearly showed that adaptability to the environment in which an individual has developed and grown is not valid in environments with different parameters, resulting even in the fatality of one sample during the experiment. In some specimens, the values of the studied hematological parameters were halved after the transfer to the new environment, and in others, the same parameters were doubled. The study concludes that the specimens were adapted to the environment in which they developed and grew, their descendants having a higher value of heritability only in the initial environment. It is known that heritability is influenced 50% by the genetic package of the individual and 50% by the environment, by removing the value of the environment, the duration of improvement of characters of interest will be shorter and the maximum yield of fish farms can be achieved in a smaller period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=heritability" title=" heritability"> heritability</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a> </p> <a href="https://publications.waset.org/abstracts/138627/the-influence-of-the-aquatic-environment-on-hematological-parameters-in-cyprinus-carpio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5139</span> Impact Evaluation of Vaccination against Eight-Child-Killer Diseases on under-Five Children Mortality at Mbale District, Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lukman%20Abiodun%20Nafiu">Lukman Abiodun Nafiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the impact evaluation of vaccination against eight-child-killer diseases on under-five children mortality at Mbale District. It was driven by three specific objectives which are to determine the proportion of under-five children mortality due to the eight-child-killer diseases to the total under-five children mortality; establish the cause-effect relationship between the eight-child-killer diseases and under-five children mortality; as well as establish the dependence of under-five children mortality in the location at Mbale District. A community based cross-sectional and longitudinal (panel) study design involving both quantitative and qualitative (focus group discussion and in-depth interview) approaches was employed over a period of 36 months. Multi-stage cluster design involving Health Sub-District (HSD), Forms of Ownership (FOO) and Health Facilities Centres (HFC) as the first, second and third stages respectively was used. Data was collected regarding the eight-child-killer diseases namely: measles, pneumonia, pertussis (whooping cough), diphtheria, poliomyelitis (polio), tetanus, haemophilus influenza, rotavirus gastroenteritis and mortality regarding immunized and non-immunized children aged 0-59 months. We monitored the children over a period of 24 months. The study used a sample of 384 children out of all the registered children for each year at Mbale Referral Hospital and other Primary Health Care Centres (HCIV, HCIII and HCII) at Mbale District between 2015 and 2019. These children were followed from birth to their current state (living or dead). The data collected in this study was analysed using cross tabulation and the chi-square test. The study concluded that majority of mothers at Mbale district took their children for immunization and thus reducing the occurrence of under-five children mortality. Overall, 2.3%, 4.6%, 3.1%, 5.4%, 1.5%, 3.8%, 0.0% and 0.0% of under-five children had polio, tetanus, diphtheria, measles, pertussis, pneumonia, haemophilus influenzae and rotavirus gastroenteritis respectively across all the sub counties at Mbale district during the period considered. Also, different locations (sub counties) do not have significant influence on the occurrence of these eight-child-killer diseases among the under-five children at Mbale district. Therefore, the study recommended that government and agencies should continue to work together to implement measures of vaccination programs and increasing access to basic health care with a continuous improvement on the social interventions to progress child survival. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diseases" title="Diseases">Diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=Mortality" title=" Mortality"> Mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=Children" title=" Children"> Children</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaccination" title=" Vaccination"> Vaccination</a> </p> <a href="https://publications.waset.org/abstracts/124374/impact-evaluation-of-vaccination-against-eight-child-killer-diseases-on-under-five-children-mortality-at-mbale-district-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5138</span> Risk Factors of Hospital Acquired Infection Mortality in a Tunisian Intensive Care Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ben%20Cheikh%20Asma">Ben Cheikh Asma</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouafia%20Nabiha"> Bouafia Nabiha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Asma"> Ammar Asma</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezzi%20Olfa"> Ezzi Olfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Meddeb%20Khaoula"> Meddeb Khaoula</a>, <a href="https://publications.waset.org/abstracts/search?q=Chouch%C3%A8ne%20Imed"> Chouchène Imed</a>, <a href="https://publications.waset.org/abstracts/search?q=Boussarsar%20Hamadi"> Boussarsar Hamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Njah%20Mansour"> Njah Mansour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Hospital Acquired Infection (HAI) constitutes an important worldwide health problem. It was associated with high mortality rate in intensive care units (ICU). This study aimed to determine HAI mortality rate in Tunisian intensive care units and identify its risk factors. Methods: We conducted a prospective observational cohort study over a 12 months period (September 15th 2015 to September 15 th 2016) in the adult medical ICU of University Hospital-Farhat Hached (Sousse-Tunisia). All patients admitted in the ICU for more than 48 hours were included in the study. We used an anonymous standardized survey record form to collect data by a medical hygienist assisted by an intensivist. We adopted definitions of Center for Diseases Control and prevention of Atlanta to detect HAI, Kaplan Meier survival analysis and Cox proportional hazard regression to identify independent risk factor of HAI mortality. Results: Of 171 patients, 67 developed ICU-acquired infection (global incidence rate=39.2%). The mean age of patients was 59 ± 21.2 years and 60.8% were male. The most frequently identified infections were pulmonary acquired infection (ventilator associated pneumonia (VAP) and infected atelectasis with density rates 21.4 VAP/1000 days of mechanical ventilation and 9.4 infected atelectasis /1000 days of mechanical ventilation; respectively) and central venous catheter associated infection (CVC - AI) with density rate 28.4 CVC-AI / 1000 CVC-days). HAI mortality rate was 66.7% (n=44). The median survival was 20 days 3.36, 95% Confidential Interval [13.39 – 26.60]. Specific mortality rates according to infectious site were 65.5%, 36.4% and 4.5% respectively for VAP, CVC associated infection and infected atelectasis. In univariate analysis, a significant associations between mortality and cardiovascular history (p=0.04) tracheotomy (p=0.00), peripheral venous catheterization (p=0.04), VAP (p=0.04) and infected atelectasis (p=0.04) were detected. Independent risk factors for HAI mortality were VAP with Hazard Ratio = 3.14, 95% Confidential Interval [1.63 – 6.05] (p=0.001) and tracheotomy (Hazard Ratio=0.22, 95% Confidential Interval [0.10 – 0.44], p=0.000). Conclusions: In the present study, hospital acquired infection mortality rate was relatively high. We need to intensify the fight against these infections especially ventilator-associated pneumonia that is associated with higher risk of mortality in many studies. Thus, more effective infection control interventions were necessary in our hospital. <p class="card-text"><strong>Keywords:</strong> <a
