In the United States, the usage of SCC has been spearheaded by the precast concrete industry. Good SCC must possess the following key fresh properties: filling ability, passing ability, and resistance to segregation. Self-compacting concrete is one of 'the most revolutionary developments' in concrete research; this concrete is able to flow and to fill the most restocked places of the form work without vibration. There are several methods for testing its properties. In the fresh state: the most frequently used are slump flow test, L box and V-funnel. This work presents properties of self-compacting concrete, mixed with fly ash. The test results for acceptance characteristics of self-compacting concrete such as slump flow; V-funnel and L-Box are presented. Further, the compressive strength at the ages of 7, 28 days was also determined and results are included here. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title=" self-compacting concrete"> self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=slump%20flow%20test" title=" slump flow test"> slump flow test</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20plasticizer" title=" super plasticizer"> super plasticizer</a> </p> <a href="https://publications.waset.org/abstracts/24964/properties-of-self-compacting-concrete-mixed-with-fly-ash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24964.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">411</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">1182</span> Investigation Acute Toxicity and Bioaccumulation Mineral Mercury in Rutilus frisii Kutum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Gharaei">A.

We carried out ten treatments with three replicates and one control for each of the chemicals using the static O. E. C. D. method in 55-liter-tanks each containing 14 fingerlings. During the experiments, the average pH was recorded as 7.8, total hardness was measured to be 255 mg/l, the average water temperature was 27±1 degrees centigrade and dissolved oxygen was 7.2 mg/l. Mean LC50 values of Hgcl2 for juvenile R. frisii kutum with mean weight 1±0.2 gr were 0.102 and 0.86 mgHg/l at 24h and 96h, respectively. The bioaccumulation values during 24h in tissue, kidney, and gill were 1.55, 16.1, and 22.7 mgHg/l, respectively. So, these values during 96h were 2.8, 16.8, and 26.65 mgHg/l, respectively. The bioconcentration factors in tissue, kidney, and gill during 24h were 14.75, 153.39, and 216.11 and so during 96h were 33.8, 198.1, and 313.5 times. These results show that bioaccumulation was highest in the gill and then kidney and tissue, respectively. This study suggested that between mercury concentrations of water with bioaccumulation in tissue more than kidney and gill. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HgCl2" title="HgCl2">HgCl2</a>, <a href="https://publications.waset.org/abstracts/search?q=LC5096h" title=" LC5096h"> LC5096h</a>, <a href="https://publications.waset.org/abstracts/search?q=bioaccumulation" title=" bioaccumulation"> bioaccumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Rutilus%20frisii%20Kutum" title=" Rutilus frisii Kutum"> Rutilus frisii Kutum</a>, <a href="https://publications.waset.org/abstracts/search?q=Caspian%20Sea" title=" Caspian Sea"> Caspian Sea</a> </p> <a href="https://publications.waset.org/abstracts/34715/investigation-acute-toxicity-and-bioaccumulation-mineral-mercury-in-rutilus-frisii-kutum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34715.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">573</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">1181</span> Acute Toxic Effects of Zn(SO4) on Gill and Liver Tissues of Fresh Water Catfish Clarias batrachus (L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muneesh%20Kumar">Muneesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar"> Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangeeta%20Devi"> Sangeeta Devi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metals are a major problem because they are toxic and tend to accumulate in living organisms. This study was carried out with the aims of studying on histopathology of Zn(SO4) toxicity on gill and liver tissues of catfish (Clarias batrachus) within the period of 96 h. Totally, 140 fishes with mean weight 50±10 g were stocked in 12 aquariums with capacity of 200 L water and divided in to 3 trails including control, 4 ppm and 8 ppm of Zn with 3 replicates. Tissue samples were fixed by bouin’s solution and sectioned in 7 μm based on histological regular method and stained with Hematoxylin and Eosin (H&E) method for microscopic study within the period of 96 h. Results showed some damaged such as hyperplasia, telangiectasis and edema, necrosis of second filaments, jerky movement, aneurism, hyperemia and fusion of second filaments in gills; and cell atrophy, necrosis, fatty degeneration, hyperemia and bile stagnation at different treatments in comparison with control. Gill and liver tissue damages were severed with the increase of Zn concentration and days. Therefore, Zn had acute toxicity effects on gill and liver tissues in Catfish at 5 and 10 ppm concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gill" title="gill">gill</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</a>, <a href="https://publications.waset.org/abstracts/search?q=Clarias%20batrachus" title=" Clarias batrachus"> Clarias batrachus</a> </p> <a href="https://publications.waset.org/abstracts/32681/acute-toxic-effects-of-znso4-on-gill-and-liver-tissues-of-fresh-water-catfish-clarias-batrachus-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32681.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">492</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">1180</span> Ingenious Use of Hypo Sludge in M25 Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhinandan%20Singh%20Gill">Abhinandan Singh Gill</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paper mill sludge is one of the major economic and environmental problems for paper and board industry, million tonnes quantity of sludge is produced in the world. It is essential to dispose these wastes safely without affecting health of human being, environment, fertile land; sources of water bodies, economy as it adversely affect the strength, durability and other properties of building materials based on them. Moreover, in developing countries like India where there is low availability of non-renewable resources and large need of building material like cement therefore it is essential to develop eco-efficient utilization of paper sludge. Primarily in functional terms paper sludge comprises of cellulose fibers, calcium carbonate, china clay, low silica, residual chemical bonds with water. The material is sticky and full of moisture content which is hard to dry. The manufacturing of paper usually produce loads of solid waste. These paper fibers are recycled in paper mills to limited number of times till they become weak to produce high quality paper. Thereafter, these left out small and weak pieces called as low quality paper fibers are detached out to become paper sludge. The material is by-product of de-inking and re-pulping of paper. This hypo sludge includes all kinds of inks, dyes, coating etc inscribed on the paper. This paper presents an overview of the published work on the use of hypo sludge in M25 concrete formulations as a supplementary cementitious material exploring its properties such as compressive strength, splitting and parameters like modulus of elasticity, density, applications and most importantly investigation of low cost concrete by using hypo sludge are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20waste" title=" sludge waste"> sludge waste</a>, <a href="https://publications.waset.org/abstracts/search?q=hypo%20sludge" title=" hypo sludge"> hypo sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=supplementary%20cementitious%20material" title=" supplementary cementitious material"> supplementary cementitious material</a> </p> <a href="https://publications.waset.org/abstracts/17252/ingenious-use-of-hypo-sludge-in-m25-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17252.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">307</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">1179</span> Task Scheduling on Parallel System Using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasbir%20Singh%20Gill">Jasbir Singh Gill</a>, <a href="https://publications.waset.org/abstracts/search?q=Baljit%20Singh"> Baljit Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scheduling and mapping the application task graph on multiprocessor parallel systems is considered as the most crucial and critical NP-complete problem. Many genetic algorithms have been proposed to solve such problems. In this paper, two genetic approach based algorithms have been designed and developed with or without task duplication. The proposed algorithms work on two fitness functions. The first fitness i.e. task fitness is used to minimize the total finish time of the schedule (schedule length) while the second fitness function i.e. process fitness is concerned with allocating the tasks to the available highly efficient processor from the list of available processors (load balance). Proposed genetic-based algorithms have been experimentally implemented and evaluated with other state-of-art popular and widely used algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parallel%20computing" title="parallel computing">parallel computing</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20scheduling" title=" task scheduling"> task scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20duplication" title=" task duplication"> task duplication</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/75569/task-scheduling-on-parallel-system-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75569.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">348</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">1178</span> Morphological Studies of the Gills of the Red Swamp Freshwater Crayfish Procambarus clarkii (Crustacea: Decapoda: Cambarids) (Girard 1852) from the River Nile and Its Branches in Egypt </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20M.%20A.%20Abumandour">Mohamed M. A.

All gills have the same general structure and appearance; plume-like with single broad setiferous, and single axis. The gill consists of axis with numerous finger-like filaments, having three morphological types; round, pointed and somewhat hooked shaped. The direction of filaments vary according their position; in middle region were nearly perpendicular to gill axis while in the apex were nearly parallel to axis. There were characteristic system of gill spines on; central axis (two types were distinguishable by presence of socket), basal plate, setobranch (long non-branched and short multidenticulate) and on the bilobed epipodal plate. There are four shape of spinated-like distal region of setobranch seta; two pointed processes (longitudinal arrangement and irregular arranged) and two broad processes (transverse triangular and multidenticulate). The bilobed epipodal plate devoid from any filaments and extended from outer side of podobranchiae as triangular basal part then extended between the gills as cord-like middle part then pass under the gill to lies against the thoracic body wall. By SEM, the apical part of bilobed epipodal plate have serrated free border and corrugated surface while the middle part have none serrated free border. There are two methods of gill cleaning mechanism in crayfish; passive and active method. The passive method occurred by; setae of setobranch, branchiostegite, bilobed epipodal plate, setiferous arthrodial lamellae and reversing the respiratory water through a narrow spaced branchial chamber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crayfis" title="crayfis">crayfis</a>, <a href="https://publications.waset.org/abstracts/search?q=gill%20spines" title=" gill spines"> gill spines</a>, <a href="https://publications.waset.org/abstracts/search?q=setobranch" title=" setobranch"> setobranch</a>, <a href="https://publications.waset.org/abstracts/search?q=gill%20setae" title=" gill setae"> gill setae</a>, <a href="https://publications.waset.org/abstracts/search?q=cleaning%20mechanisms" title=" cleaning mechanisms"> cleaning mechanisms</a> </p> <a href="https://publications.waset.org/abstracts/18645/morphological-studies-of-the-gills-of-the-red-swamp-freshwater-crayfish-procambarus-clarkii-crustacea-decapoda-cambarids-girard-1852-from-the-river-nile-and-its-branches-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18645.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">410</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">1177</span> Behavioral Changes and Gill Histopathological Alterations of Red Hybrid Tilapia (Oreochromis sp.)

The pollution of glyphosate in the aquatic environment can be via water run-off from agricultural lands, or by spray drift, aerial spraying or due to industrial discharge, which may be seen as a threat to aquatic biota. Fish is one of the best organisms to study the toxicological aspects of glyphosate. A 49 days experiment was conducted under laboratory conditions to ascertain the effects of technical grade glyphosate on behaviour and histopathological conditions in the gills of red hybrid tilapia using a light inverted microscope. Air gasping, erratic swimming, fin movement, mucus secretion, hemorrhages, and loss of scales were observed as behavioural changes in the exposed fish. There was no histopathological complication observed in the gill of the control fish, but various levels of alterations were seen in the gills of the fish exposed to glyphosate herbicide. These include lifting of primary lamella, congestion of secondary lamella, as well as hyperplasia in both primary and secondary gill lamella, and hypertrophy of secondary gill lamella. Based on the findings of this study, glyphosate herbicide exerts behavioural and histopathological changes in the gill of red hybrid tilapia, and therefore, the fish is considered a good bioindicator in aquatic environment monitoring. Excessive usage of glyphosate herbicide near aquatic habitats should be discouraged. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavioural" title="behavioural">behavioural</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathological" title=" histopathological"> histopathological</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis%20niloticus" title=" Oreochromis niloticus"> Oreochromis niloticus</a>, <a href="https://publications.waset.org/abstracts/search?q=glyphosate" title=" glyphosate"> glyphosate</a> </p> <a href="https://publications.waset.org/abstracts/187898/behavioral-changes-and-gill-histopathological-alterations-of-red-hybrid-tilapia-oreochromis-sp-exposed-to-glyphosate-herbicide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187898.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">47</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">1176</span> Fish Species Composition and Distribution of a Semi-Oxbow Lake in North Central Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adeyemi">Adeyemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Olusegun"> Samuel Olusegun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper reports on the result of experimental gill net assessment of the fishery of Gbedikere Lake in Kogi State between October 2006 and September 2008.

Heavy metals are non-biodegradable, persist in the environment, and are concentrated up to the food chain, leading to enhanced levels in the liver and muscle tissues of fishes, aquatic bryophytes, and aquatic biota. Marine organisms, in general fish in particular, accumulate metals to concentrations many times higher than present in water or sediment as they can take up metals in their organs and concentrate at different levels. Thus, metals acquired through the food chain due to pollution are potential chemical hazards, threatening consumers. The Nile tilapia (oreochromic niloticus), catfish (clarius garpinus), and water samples were collected from five sampling sites, namely, inlet-1, inlet-2, center, outlet-1 and outlet-2 of Lake Chamo. The concentration of major and trace metals Na, K, Mg, Ca, Cr, Co, Ni, Mn and Cu in the two fish muscles, gill and liver, was determined using an atomic absorption spectrometer (AAS) and flame photometer (FP). Metal concentrations in the water have also been evaluated within the two consecutive seasons, winter (dry) and spring (wet). The results revealed that the concentration of those metals in Tilapia’s (O. niloticus) muscle, gill, and liver were Na 44.5, 35.1, 28, Mg 2.8, 8.41, 4.61, K 43, 32, 30, Ca 1.5, 6.0, 5.5, Cr 0.91, 1.2, 3.5, Co 3.0, 2.89, 2.62, Ni 0.94, 1.99, 2.2, Mn 1.23, 1.51, 1.6 and Cu 1.1, 1.99, 3.5 mg kg-1 respectively and in catfish’s muscle, gill and liver Na 25, 39, 41.5, Mg 4.8, 2.87, 6, K 29, 38, 40, Ca 2.5, 8.10, 3.0, Cr 0.65, 3.5, 5.0, Co 2.62, 1.86, 1.73, Ni 1.10, 2.3, 3.1, Mn 1.54, 1.57, 1.59 and Cu 1.01, 1.10, 3.70 mg kg-1 respectively. The highest accumulation of Na and K were observed for tilapia muscle and catfish gill, Mg and Ca got higher in tilapia gill and catfish liver, while Co is higher in muscle of the two fish. The Cr, Ni, Mn and Cu levels were higher in the livers of the two fish species. In conculusion, metal toxicity through food chain is the current dangerous issue for human and othe animals. This needs deep focus to promot the health of living animals. The Details of the work are going to be discussed at the conference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioaccumulation" title="bioaccumulation">bioaccumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=catfish" title=" catfish"> catfish</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20metals" title=" essential metals"> essential metals</a>, <a href="https://publications.waset.org/abstracts/search?q=nile%20tilapia" title=" nile tilapia"> nile tilapia</a> </p> <a href="https://publications.waset.org/abstracts/168125/chemical-speciation-and-bioavailability-of-some-essential-metal-ions-in-different-fish-organs-at-lake-chamo-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168125.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">1173</span> Exposure of Pacu, Piaractus mesopotamicus Gill Tissue to a High Stocking Density: An Ion Regulatory and Microscopy Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wiolene%20Montanari%20Nordi">Wiolene Montanari Nordi</a>, <a href="https://publications.waset.org/abstracts/search?q=Debora%20Botequio%20Moretti"> Debora Botequio Moretti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Caroline%20Pontin"> Mariana Caroline Pontin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Pampolini"> Jessica Pampolini</a>, <a href="https://publications.waset.org/abstracts/search?q=Raul%20Machado-Neto"> Raul Machado-Neto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gills are organs responsible for respiration and osmoregulation between the fish internal environment and water. Under stress conditions, oxidative response and gill plasticity to attempt to increase gas exchange area are noteworthy, compromising the physiological processes and therefore fish health. Colostrum is a dietary source of nutrients, immunoglobulin, antioxidant and bioactive molecules, essential for immunological protection and development of the gastrointestinal epithelium. The hypothesis of this work is that antioxidant factors present in the colostrum, unprecedentedly tested in gills, can minimize or reduce the alteration of its epithelium structure of juvenile pacu (Piaractus mesopotamicus) subjected to high stocking density. The histological changes in the gills architecture were characterized by the frequency, incidence and severity of the tissue alteration and ionic status. Juvenile (50 kg fish/m3) were fed with pelleted diets containing 0, 10, 20 or 30% of lyophilized bovine colostrum (LBC) inclusion and at 30 experimental days, gill and blood samples were collected in eight fish per treatment. The study revealed differences in the type, frequency and severity (histological alterations index – HAI) of tissue alterations among the treatments, however, no distinct differences in the incidence of alteration (mean alteration value – MAV) were observed. The main histological changes in gill were elevation of the lamellar epithelium, excessive cell proliferation of the filament and lamellar epithelium causing total or partial melting of the lamella, hyperplasia and hypertrophy of lamellar and filament epithelium, uncontrolled thickening of filament and lamellar tissues, mucous and chloride cells presence in the lamella, aneurysms, vascular congestion and presence of parasites. The MAV obtained per treatment were 2.0, 2.5, 1.8 and 2.5 to fish fed diets containing 0, 10, 20 and 30% of LBC inclusion, respectively, classifying the incidence of gill alterations as slightly to moderate. The severity of alteration of individual fish of treatment 0, 10 and 20% LBC ranged values from 5 to 40 (HAI average of 20.1, 17.5 and 17.6, respectively, P > 0.05), and differs from 30% LBC, that ranged from 6 to 129 (HAI mean of 77.2, P < 0.05). The HAI value in the treatments 0, 10 and 20% LBC reveals gill tissue with injuries classified from slightly to moderate, while in 30% LBC moderate to severe, consequence of the onset of necrosis in the tissue of two fish that compromises the normal functioning of the organ. In relation to frequency of gill alterations, evaluated according to absence of alterations (0) to highly frequent (+++), histological alterations were observed in all evaluated fish, with a trend of higher frequency in 0% LBC. The concentration of Na+, Cl-, K+ and Ca2+ did not changed in all treatments (P > 0.05), indicating similar capacity of ion exchange. The concentrations of bovine colostrum used in diets of present study did not impair the alterations observed in the gills of juvenile pacu. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=histological%20alterations%20of%20gill%20tissue" title="histological alterations of gill tissue">histological alterations of gill tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20status" title=" ionic status"> ionic status</a>, <a href="https://publications.waset.org/abstracts/search?q=lyophilized%20bovine%20colostrum" title=" lyophilized bovine colostrum"> lyophilized bovine colostrum</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20microscopy" title=" optical microscopy"> optical microscopy</a> </p> <a href="https://publications.waset.org/abstracts/67775/exposure-of-pacu-piaractus-mesopotamicus-gill-tissue-to-a-high-stocking-density-an-ion-regulatory-and-microscopy-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67775.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">299</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">1172</span> Tissue-Specific Distribution of Cytochrome P450 1A1 and 3A in Rainbow Trout (Oncorhynchus mykiss)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viktoriia%20Burkina">Viktoriia Burkina</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Zlabek"> Vladimir Zlabek</a>, <a href="https://publications.waset.org/abstracts/search?q=Galia%20Zamaratskaia"> Galia Zamaratskaia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cytochromes P450 (CYP) are important family of enzymes in Phase I metabolism. Environmental pollutants often act as inducers of the gene expression and activities CYP1A1 and CYP3A-like isoforms in fish. The activities are generally measured in the fish liver or gills, and less is known about tissue distribution of expression. In present study, the CYP1A1 and CYP3A-like activities were measured in rainbow trout liver, gill, intestine, heart, brain and gonads. The activities of CYP1A1 and CYP3A-like proteins were estimated as the rates of 7-ethoxyresorufin-O-deethylation (EROD) and benzyloxy-4-trifluoromethylcoumarin-O-debenzyloxylation (BFCOD), respectively. The CYP1A1 and CYP3A-like activities were detectable in all investigated fish tissues, with the highest activity in hepatic tissue followed by heart > brain > gill > intestine > gonads. To confirm the presence of CYP1A1 in different tissues, EROD activity was measured in presence of the selective inhibitors ellipticine (CYP1A1), ketoconazole (CYP3A), 8-methoxypsoralen (human CYP2A) and diallyl sulphide (CYP2E1). It was found that ellipticine, ketoconazole and 8-methoxypsoralen inhibited hepatic EROD activity by 88-98%. Ellipticine inhibited gill, intestine, and gonad EROD activity by 50%. In conclusion, EROD and BFCOD activities were detected in rainbow trout liver, gill, intestine, heart, brain and gonads. Further studies are needed to fully identify all CYP450 isoforms responsible for these activities.

The evaluation of a language is an eminent task in the era of information retrieval and text mining. The extraction and classification of knowledge from text can be exploited for sentiment analysis and morphological evaluation. This study coalesce morphological evaluation and sentiment analysis for the task of classification of farmer suicide cases reported in Punjab state of India. The pre-processing of Punjabi text involves morphological evaluation and normalization of Punjabi word tokens followed by the training of proposed model using deep learning classification on Punjabi language text extracted from online Punjabi news reports. The class-wise accuracies of sentiment prediction for four negatively oriented classes of farmer suicide cases are 93.85%, 88.53%, 83.3%, and 95.45% respectively.

Friction stir welding is a solid state welding process which is most suitable for the welding of nonferrous alloys, especially aluminum and magnesium alloys. Aluminum and magnesium alloys are widely used for structural applications of all types of automobiles due to their superior mechanical properties with their low density. This paper deals with the critical review of the different properties (like tensile strength, microhardness, impact strength, corrosion resistance, and metallurgical investigation on SEM) obtained by the FSW of aluminum and magnesium alloys. After a critical review of the existing published literature on concerned topics, all the properties of welding joins are compared in the tabulated manner to optimize the selection of materials and FSW parameters according to mechanical and tribological properties. Different tool designs used for the FSW process are also thoroughly studied, and the influence of the design of the tool used in FSW on the different properties has also been incorporated in this paper. It has been observed from the existing published literature that FSW is the most effective and practical technique for joining the non ferrous alloys especially aluminum and magnesium alloys, and among the different FSW tools, left hand threaded tri-flute (LHTTF) tool is best for the welding of non ferrous alloys like aluminum and magnesium alloys which gives the superior mechanical properties to welding joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum" title="aluminum">aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20applications" title=" structural applications"> structural applications</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20design" title=" tool design"> tool design</a> </p> <a href="https://publications.waset.org/abstracts/108193/a-review-on-the-studies-on-mechanical-and-tribological-properties-of-aluminum-and-magnesium-alloys-welded-by-friction-stir-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108193.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">179</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">1169</span> Histopathological Effects of Trichodiniasis in Farmed Freshwater Rainbow Trout, Oncorhynchus mykiss, in West of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Khoshnood">Zahra Khoshnood</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Khoshnood"> Reza Khoshnood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of present study was to monitor the presence of Trichodina sp. in Rainbow trout, Oncorhynchus mykiss collected from various fish farms in the western provinces of Iran during January, 2013- January, 2014. Out of 675 sampled fish 335, (49.16%) were infested with Trichodina. The highest prevalence was observed in the spring and winter followed by autumn and summer. In general, the intensity of infection was low except in cases where outbreaks of Trichodiniasis endangered the survival of fish in some ponds. In light infestation Trichodina is usually present on gills, fins and skin of apparently healthy fish. Clinical signs of Trichodiniasis only appear on fish with heavy infections and cases of moderate ones that are usually exposed to one or more stress factors including, rough handling during transportation from ponds, overcrowdness, malnutrition, high of free ammonia and low of oxygen concentration. Clinical signs of Trichodiniasis in sampled fish were sluggish movement, loss of appetite, black coloration, necrosis and ulcer on different parts of the body, detached scales and excessive accumulation of mucous in gill pouches. The most obvious histopathological changes in diseased fish were sloughing of the epidermal layer, aggregation of leucocytes and melanine-carrying cells (between the dermis and hypodermis) and proliferative changes including hyperplasia and hypertrophy of the epithelial lining cells of gill filaments which resulted in fusion of secondary lamellae. Control of Trichodiniasis, has been achieved by formalin bath treatment at a concentration of 250 ppm for one hour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gill" title="gill">gill</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <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=Trichodina" title=" Trichodina"> Trichodina</a> </p> <a href="https://publications.waset.org/abstracts/11484/histopathological-effects-of-trichodiniasis-in-farmed-freshwater-rainbow-trout-oncorhynchus-mykiss-in-west-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11484.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">426</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">1168</span> Adopting a Systematically Planned Humour Pedagogical Approach to Increase Student Engagement in Higher Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rita%20Gill%20Singh">Rita Gill Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Chun%20Koon"> Alex Chun Koon</a>, <a href="https://publications.waset.org/abstracts/search?q=Cindy%20Sing%20Bik%20Ngai"> Cindy Sing Bik Ngai</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Wen%20Ying%20Ho"> Joanna Wen Ying Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei%20Li%20Khong"> Mei Li Khong</a>, <a href="https://publications.waset.org/abstracts/search?q=Enoch%20Chan"> Enoch Chan</a>, <a href="https://publications.waset.org/abstracts/search?q=Terrence%20Lau"> Terrence Lau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although humour is viewed as a beneficial element in teaching, there has been little attempt to systematize humour in teaching, possibly because it is difficult to teach someone to be humorous. This study integrated planned humour pedagogical approach into teaching and learning activities and examined the effect of systematically planned humour on students’ engagement and learning in different courses. Specifically, appropriate types of humour (i.e. analogy, absurdity and wordplay) and incorporation methods and frequency were systematically integrated into the lessons of courses at some higher education institutions in Hong Kong. The results showed that the planned humour pedagogical approach increased student engagement, as well as enhanced learning and motivation while reducing students’ stress. The pedagogical implications of this study will be useful for researchers, practitioners, and educators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title="higher education">higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=humour" title=" humour"> humour</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20engagement" title=" student engagement"> student engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a> </p> <a href="https://publications.waset.org/abstracts/184448/adopting-a-systematically-planned-humour-pedagogical-approach-to-increase-student-engagement-in-higher-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184448.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">62</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">1167</span> Studies on Corrosion Resistant Composite Coating for Metallic Surfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Navneetinder%20Singh">Navneetinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Harprabhjot%20Singh"> Harprabhjot Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Harpreet%20Singh"> Harpreet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Supreet%20Singh"> Supreet Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many materials are known to mankind that is widely used for synthesis of corrosion resistant hydrophobic coatings. In the current work, novel hydrophobic composite was synthesized by mixing polytetrafluoroethylene (PTFE) and 20 weight% ceria particles followed by sintering. This composite had same hydrophobic behavior as PTFE. Moreover, composite showed better scratch resistance than virgin PTFE. Pits of plasma sprayed Ni₃Al coating were exploited to hold PTFE composite on the substrate as Superni-75 alloy surface through sintering process. Plasma sprayed surface showed good adhesion with the composite coating during scratch test. Potentiodynamic corrosion test showed 100 fold decreases in corrosion rate of coated sample this may be attributed to inert and hydrophobic nature of PTFE and ceria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polytetrafluoroethylene" title="polytetrafluoroethylene">polytetrafluoroethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=PTFE" title=" PTFE"> PTFE</a>, <a href="https://publications.waset.org/abstracts/search?q=ceria" title=" ceria"> ceria</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a> </p> <a href="https://publications.waset.org/abstracts/94265/studies-on-corrosion-resistant-composite-coating-for-metallic-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94265.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">383</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">1166</span> Biogeochemical Study of Polycuclic Aromatic Hydrocarbons and Its Physiological Response in Mudskippre (B. dussumieri) along the North western Coasts of the Persian Gulf</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mashinchian%20Moradi">Ali Mashinchian Moradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmood%20Sinaei"> Mahmood Sinaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Study on the biomarkers to assess health status of marine ecosystems has an important value in biomonitoring of marine environment. Accordingly, accumulation of polycyclic aromatic hydrocarbons in sediment, water and tissues (liver and gill) of mudskipper (Boleophthalmus dussmieri) and some physiological responses like lysosomal membrane change in haemocytes and the Glutathione-S Transferase (GST) activity in the liver were measured in mudskippers. Samples were collected from five sites along the noth western cost of the Persian Gulf. PAHs concentration was measured by HPLC method. The activity of GST enzyme was analysed by spectrophotometric method. Total PAH concentration in coastal seawater, sediments, liver and gill tissues ranged between 0.80-18.34 ug/L, 113.550-3384.34 ng/g dw, 3.99-46.64 ng/g dw and 3.11-17.This study showed that PAH concentrations in this region are not higher than available standards. The findings revile that lysosomal membrane destabilization and liver GST activities are highly sensitive to PAHs in mudskipper, B. dussumieri. Sediment PAH concentrations were strongly correlated with biomarkers, indicating PAHs were biologically available to fish. Thus, mudskipper perceived to be good sentinel organism for PAH pollution biomonitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PAHs" title="PAHs">PAHs</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=mudskipper" title=" mudskipper"> mudskipper</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20Gulf" title=" Persian Gulf"> Persian Gulf</a> </p> <a href="https://publications.waset.org/abstracts/31864/biogeochemical-study-of-polycuclic-aromatic-hydrocarbons-and-its-physiological-response-in-mudskippre-b-dussumieri-along-the-north-western-coasts-of-the-persian-gulf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31864.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">346</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">1165</span> Influence of Post Weld Heat Treatment on Mechanical and Metallurgical Properties of TIG Welded Aluminium Alloy Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema">Gurmeet Singh Cheema</a>, <a href="https://publications.waset.org/abstracts/search?q=Navjotinder%20Singh"> Navjotinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh"> Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh"> Amardeep Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aluminium and its alloys play have excellent corrosion resistant properties, ease of fabrication and high specific strength to weight ratio.

Ni20Cr and Al2O3-13TiO2 powders were sprayed using detonation gun onto GI250 and GIHC substrates and the results as well as coating surface morphology of the coating is studied by XRD and SEM/EDAX analysis. The wear resistance of Ni20Cr and Al2O3-13TiO2 has been investigated on pin-on-disc tribometer using ASTM G99 standards. Cumulative wear rate and coefficient of friction (µ) were calculated under three normal load of 30N, 40N, 50N at constant sliding velocity of 1m/s. Worn out surfaces were analyzed by SEM/EDAX. The results show significant resistance to wear with Al2O3-13TiO2 coating as compared to Ni20Cr and bare substrates. SEM/EDAX analysis and cumulative wear loss bar charts clearly explain the wear behavior of coated as well as bare sample of GI250 and GIHC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=detonation%20spray" title="detonation spray">detonation spray</a>, <a href="https://publications.waset.org/abstracts/search?q=grey%20cast%20iron" title=" grey cast iron"> grey cast iron</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20rate" title=" wear rate"> wear rate</a>, <a href="https://publications.waset.org/abstracts/search?q=coefficient%20of%20friction" title=" coefficient of friction"> coefficient of friction</a> </p> <a href="https://publications.waset.org/abstracts/8636/wear-behavior-of-grey-cast-iron-coated-with-al2o3-13tio2-and-ni20cr-using-detonation-spray-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8636.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">367</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">1163</span> Snails and Fish as Pollution Biomarkers in Lake Manzala and Laboratory B: Lake Manzala Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20M.%20M.%20El-Khayat">Hanaa M.

All fish samples showed a significant increase in levels of alkaline phosphatase (ALP), creatinine and glutathione-S-transferase (GST); only Dakahlya samples showed a significant increase (p<0.01) in aspartate aminotransferase (AST) level and most Dakahlya and Damietta samples showed reversed albumin and globulin ratio and a significant increase in γ-glutamyltransferase (GGT) level. Port-Said and Damietta samples showed a significant decrease of hemoglobin (Hb) while Dakahlya samples showed a significant decrease in white blood cell (WBC) count. Histopathological investigation for different fish organs showed that Port-Said and Dakahlya samples were more altered than Damietta. The muscle and gill followed by intestine were the most affected organs. The muscle sections showed severe edema, neoplasia, necrotic change, fat vacuoles and splitting of muscle fiber. The gill sections showed dilated blood vessels of the filaments, curling of gill lamellae, severe hyperplasia, edema and blood vessels congestion of filaments. The intestine sections revealed degeneration, atrophy, dilation in blood vessels and necrotic changes in sub-mucosa and mucosa with edema in between. The recorded significant alterations, in most of the physiological and histological parameters in <em>O. niloticus</em> samples from Lake Manzala, were alarming for water pollution impacts on lake fish community, which constitutes the main diet and the main source of income for the people inhabiting these areas, and were threatening their public health and economy. Also, results evaluate the use of <em>O. niloticus</em> fish as important bio-indicator for their habitat stressors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lake%20Manzala" title="Lake Manzala">Lake Manzala</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis%20niloticus%20fish" title=" Oreochromis niloticus fish"> Oreochromis niloticus fish</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pollution" title=" water pollution"> water pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological" title=" physiological"> physiological</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20and%20histopathological%20parameters" title=" hematological and histopathological parameters"> hematological and histopathological parameters</a> </p> <a href="https://publications.waset.org/abstracts/54438/snails-and-fish-as-pollution-biomarkers-in-lake-manzala-and-laboratory-b-lake-manzala-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54438.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">312</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">1162</span> Performance Analysis of VoIP Coders for Different Modulations Under Pervasive Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jasbinder%20Singh">Jasbinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Harjit%20Pal%20Singh"> Harjit Pal Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20A.%20Khan"> S.

This management change is likely to improve the potential for more desirable stock structures through natural recruitment. Barramundi (Lates calcarifer) is one of the popular target fish for recreational and commercial fishers in Northern Australia. This investigation examines the effects of reduced commercial fishing from both biological and economic perspectives, particularly on the local Barramundi population of the Fitzroy River in Rockhampton, the largest river catchment flowing to the eastern coast of Australia. Data on different parameters of biological and economic aspects have been collated from secondary sources for analysis through a system simulation approach to identify the effectiveness of the commercial netting closures on recreational fishing effort, especially for the Barramundi population. The results have the potential to explain certain consequences of the netting closures in Queensland, which could serve to inform future fisheries management decisions. The study output as a whole will help in the better management of fisheries resources by evaluating recreational fishing opportunities in Queensland, where the potential for increases in recreation is high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barramundi" title="Barramundi">Barramundi</a>, <a href="https://publications.waset.org/abstracts/search?q=bioeconomic%20model" title=" bioeconomic model"> bioeconomic model</a>, <a href="https://publications.waset.org/abstracts/search?q=fishery%20management" title=" fishery management"> fishery management</a>, <a href="https://publications.waset.org/abstracts/search?q=recreational%20fishing" title=" recreational fishing"> recreational fishing</a> </p> <a href="https://publications.waset.org/abstracts/88961/bioeconomic-modelling-for-barramundi-lates-calcarifer-in-queensland-implications-for-recreational-fishing-following-recent-gill-netting-closures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88961.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">166</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">1160</span> Estimation of Population Mean Using Characteristics of Poisson Distribution: An Application to Earthquake Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prayas%20Sharma">Prayas Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposed a generalized class of estimators, an exponential class of estimators based on the adaption of Sharma and Singh (2015) and Solanki and Singh (2013), and a simple difference estimator for estimating unknown population mean in the case of Poisson distributed population in simple random sampling without replacement. The expressions for mean square errors of the proposed classes of estimators are derived from the first order of approximation. It is shown that the adapted version of Solanki and Singh (2013), the exponential class of estimator, is always more efficient than the usual estimator, ratio, product, exponential ratio, and exponential product type estimators and equally efficient to simple difference estimator. Moreover, the adapted version of Sharma and Singh's (2015) estimator is always more efficient than all the estimators available in the literature. In addition, theoretical findings are supported by an empirical study to show the superiority of the constructed estimators over others with an application to earthquake data of Turkey. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auxiliary%20attribute" title="auxiliary attribute">auxiliary attribute</a>, <a href="https://publications.waset.org/abstracts/search?q=point%20bi-serial" title=" point bi-serial"> point bi-serial</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20square%20error" title=" mean square error"> mean square error</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20random%20sampling" title=" simple random sampling"> simple random sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=Poisson%20distribution" title=" Poisson distribution"> Poisson distribution</a> </p> <a href="https://publications.waset.org/abstracts/171049/estimation-of-population-mean-using-characteristics-of-poisson-distribution-an-application-to-earthquake-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171049.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">155</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">1159</span> Sexual Harassment at Workplace in Cuttack District</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anasuya%20P.%20Pradhan">Anasuya P.

Sexual harassment in the work place has emerged as a growing obstacle in women’s progress and being a sex discrimination issue has made the society vulnerable.Such issues indicate that, today women are comparatively more insecure in our society irrespective of their social status, position, and educational qualification. Hence, it needs to be addressed in the academic pedagogy.The study aimed to learn how far people are gender-sensitized, how far they are aware about the laws related to the issue, and how far women employees raise their voice against it. The findings revealed that even being educated and working in the organized sectors, people are unaware and are not sensitized. The study therefore recommends both the Government and managers of institutions how to critically identify the root causes of sexual harassment, its implications on our society and how best to address it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=workplace%20power" title="workplace power">workplace power</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20discrimination" title=" gender discrimination"> gender discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20sensitization" title=" gender sensitization"> gender sensitization</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20harassment" title=" sexual harassment"> sexual harassment</a> </p> <a href="https://publications.waset.org/abstracts/80496/sexual-harassment-at-workplace-in-cuttack-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80496.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">196</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">1158</span> Mind-Wandering and Attention: Evidence from Behavioral and Subjective Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riya%20Mishra">Riya Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Trayambak%20Tiwari"> Trayambak Tiwari</a>, <a href="https://publications.waset.org/abstracts/search?q=Anju%20Lata%20Singh"> Anju Lata Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20L.%20Singh"> I.

It was found that thought probing rate has a negative trend with vigilance task performance whereas the subjective measures of mind-wandering have a positive relation with thought probe rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criterion%20response" title="criterion response">criterion response</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20status" title=" mental status"> mental status</a>, <a href="https://publications.waset.org/abstracts/search?q=mind-wandering" title=" mind-wandering"> mind-wandering</a>, <a href="https://publications.waset.org/abstracts/search?q=thought%20probe" title=" thought probe"> thought probe</a>, <a href="https://publications.waset.org/abstracts/search?q=vigilance" title=" vigilance"> vigilance</a> </p> <a href="https://publications.waset.org/abstracts/61046/mind-wandering-and-attention-evidence-from-behavioral-and-subjective-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61046.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">423</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">1157</span> Characterisation and in vitro Corrosion Resistance of Plasma Sprayed Hydroxyapatite and Hydroxyapatite: Silicon Oxide Coatings on 316L SS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurpreet%20Singh">Gurpreet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazoor%20Singh"> Hazoor Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Buta%20Singh%20Sidhu"> Buta Singh Sidhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current investigation plasma spray technique was used for depositing hydroxyapatite (HA) and HA – silicon oxide (SiO2) coatings on 316L SS substrate. In HA-SiO2 coating, 20 wt% SiO2 was mixed with HA. The feedstock and coatings were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM)/energy-dispersive X-ray spectroscopy (EDX) analyses. The corrosion resistance of the uncoated, HA coated and HA + 20 wt% SiO2 coated 316L SS was investigated by electrochemical corrosion testing in simulated human body fluid (Ringer’s solution). The influence of SiO2 (20 wt%) on corrosion resistance was determined. After the corrosion testing, the samples were analyzed by XRD and SEM/EDX analyses. The addition of SiO2 reduces the crystallinity of the coating. The corrosion resistance of the 316L SS was found to increase after the deposition of the HA + 20 wt% SiO2 and HA coatings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HA" title="HA">HA</a>, <a href="https://publications.waset.org/abstracts/search?q=SiO2" title=" SiO2"> SiO2</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=Ringer%E2%80%99s%20solution" title=" Ringer’s solution"> Ringer’s solution</a>, <a href="https://publications.waset.org/abstracts/search?q=316L%20SS" title=" 316L SS"> 316L SS</a> </p> <a href="https://publications.waset.org/abstracts/9141/characterisation-and-in-vitro-corrosion-resistance-of-plasma-sprayed-hydroxyapatite-and-hydroxyapatite-silicon-oxide-coatings-on-316l-ss" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9141.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">419</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">1156</span> Reduction of Wear via Hardfacing of Rotavator Blades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh%20Randhawa">Gurjinder Singh Randhawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonny%20Garg"> Jonny Garg</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukhraj%20Singh"> Sukhraj Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema"> Gurmeet Singh Cheema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A major problem related to the use of rotavator is wear of rotavator blades due to abrasion by soil hard particles, as it seriously affects tillage quality and agricultural production economy. The objective of this study was to increase the wear resistance by covering the rotavator blades with two different hard facing electrodes. These blades are generally produced from low carbon or low alloy steel. During the field work i.e. preparing land for the cultivation these blades are subjected to severe wear conditions. Comparative wear tests on a regular rotavator blade and two kinds of hardfacing with electrodes were conducted in the field. These two different hardfacing electrodes, which are designated HARD ALLOY-400 and HARD ALLOY-650, were used for hardfacing. The wear rate in the field tests was found to be significantly different statistically. When the cost is taken into consideration; HARD ALLOY-650 and HARD ALLOY-400 have been found to be the best hardfacing electrodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hardfacing" title="hardfacing">hardfacing</a>, <a href="https://publications.waset.org/abstracts/search?q=rotavator%20blades" title=" rotavator blades"> rotavator blades</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20alloy-400" title=" hard alloy-400"> hard alloy-400</a>, <a href="https://publications.waset.org/abstracts/search?q=abrasive%20wear" title=" abrasive wear"> abrasive wear</a> </p> <a href="https://publications.waset.org/abstracts/52466/reduction-of-wear-via-hardfacing-of-rotavator-blades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52466.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">425</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">1155</span> Effect of Ultrasonic Vibration on the Dilution, Mechanical, and Metallurgical Properties in Cladding of 308 on Mild Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Singh%20Sandhu">Sandeep Singh Sandhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Karanvir%20Singh%20Ghuman"> Karanvir Singh Ghuman</a>, <a href="https://publications.waset.org/abstracts/search?q=Parminder%20Singh%20Saini">Parminder Singh Saini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present investigation was to study the effect of ultrasonic vibration on the cladding of the AISI 308 on the mild steel plates using the shielded metal arc welding (SMAW). Ultrasonic vibrations were applied to molten austenitic stainless steel during the welding process. Due to acoustically induced cavitations and streaming there is a complete mixture of the clad metal and the base metal. It was revealed that cladding of AISI 308 over mild steel along with ultrasonic vibrations result in uniform and finer grain structures. The effect of the vibration on the dilution, mechanical properties and metallographic studies were also studied. It was found that the welding done using the ultrasonic vibration has the less dilution and CVN value for the vibrated sample was also high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surfacing" title="surfacing">surfacing</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20vibrations" title=" ultrasonic vibrations"> ultrasonic vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=shielded%20metal%20arc%20welding" title=" shielded metal arc welding"> shielded metal arc welding</a> </p> <a href="https://publications.waset.org/abstracts/33132/effect-of-ultrasonic-vibration-on-the-dilution-mechanical-and-metallurgical-properties-in-cladding-of-308-on-mild-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33132.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">492</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">1154</span> Genetic Instabilities in Marine Bivalve Following Benzo(α)pyrene Exposure: Utilization of Combined Random Amplified Polymorphic DNA and Comet Assay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mengjie%20Qu">Mengjie Qu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Wang"> Yi Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiawei%20Ding"> Jiawei Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Siyu%20Chen"> Siyu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanan%20Di"> Yanan Di</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Marine ecosystem is facing intensified multiple stresses caused by environmental contaminants from human activities. Xenobiotics, such as benzo(α)pyrene (BaP) have been discharged into marine environment and cause hazardous impacts on both marine organisms and human beings. As a filter-feeder, marine mussels, Mytilus spp., has been extensively used to monitor the marine environment. However, their genomic alterations induced by such xenobiotics are still kept unknown. In the present study, gills, as the first defense barrier in mussels, were selected to evaluate the genetic instability alterations induced by the exposure to BaP both in vivo and in vitro. Both random amplified polymorphic DNA (RAPD) assay and comet assay were applied as the rapid tools to assess the environmental stresses due to their low money- and time-consumption. All mussels were identified to be the single species of Mytilus coruscus before used in BaP exposure at the concentration of 56 μg/l for 1 & 3 days (in vivo exposure) or 1 & 3 hours (in vitro). Both RAPD and comet assay results were showed significantly increased genomic instability with time-specific altering pattern. After the recovery period in 'in vivo' exposure, the genomic status was as same as control condition. However, the relative higher genomic instabilities were still observed in gill cells after the recovery from in vitro exposure condition. Different repair mechanisms or signaling pathway might be involved in the isolated gill cells in the comparison with intact tissues. The study provides the robust and rapid techniques to exam the genomic stability in marine organisms in response to marine environmental changes and provide basic information for further mechanism research in stress responses in marine organisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genotoxic%20impacts" title="genotoxic
