For electron-wave modulation, a periodic voltage of frequency f was applied to the channel. Furthermore, we examined the voltage-amplitude dependence of the signals in time and frequency domains and found that large applied voltage deformed the output-signal waveform and created additional side modes (frequencies) near the modulation frequency f and that there was a trade-off between on-off ratio and side-mode creation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20conduction" title="electrical conduction">electrical conduction</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20interference" title=" electron interference"> electron interference</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20spectrum" title=" frequency spectrum"> frequency spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=on-off%20ratio" title=" on-off ratio"> on-off ratio</a> </p> <a href="https://publications.waset.org/abstracts/145444/signal-on-off-ratio-and-output-frequency-analysis-of-semiconductor-electron-interference-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145444.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">121</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">12705</span> Injury Characteristics and Outcome of Road Traffic Accident among Victims at Adult Emergency Department of Tikur Anbesa Specialized Hospital, Addis Ababa, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Seid">Mohammed Seid</a>, <a href="https://publications.waset.org/abstracts/search?q=Aklilu%20Azazh"> Aklilu Azazh</a>, <a href="https://publications.waset.org/abstracts/search?q=Fikre%20Enquselassie"> Fikre Enquselassie</a>, <a href="https://publications.waset.org/abstracts/search?q=Engida%20Yisma"> Engida Yisma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Road traffic injuries are the eighth leading cause of death globally, and the leading cause of death for young people. More than a million people die each year on the world’s roads, and the risk of dying as a result of a road traffic injury is highest in the Africa. Methods: A prospective hospital-based study was undertaken to assess injury characteristics and outcome of road traffic accident among victims at Adult Emergency Department of Tikur Anbesa specialized hospital, Addis Ababa, Ethiopia. A structured pre-tested questionnaire was used to gather the required data. The collected data were analyzed using SPSS version 16.0. Results: A total of 230 road traffic accident victims were studied. The majority of the study subjects were men 165 (71.7%) and the male/female ratio was 2.6:1. The victims’ ages ranged from 14 to 80 years with the mean and standard deviations of 32.15 and ± 14.38 years respectively. Daily laborers (95 (41.3%)) and students (28 (12.2%)) were the majority of road traffic accident victims. Long-distance travelling Minibus (16.5%) was responsible for the majority of road traffic crash followed by followed by Taxi (14.8%) and pedestrians (62.6%) accounted for the majority of road traffic accident. Head (50.4%) and musculoskeletal (extremities) (47.0%) were the most common body region injured. Fractures (78.0%) and open wounds (56.5%) were the most common type of injuries sustained. Treatment of fracture was the most common procedure performed in 57.7 % of the victims. The overall length of hospital stay (LOS) ranged from 1 day to 61 days with mean (± standard deviation) of 7.12 ± 10.5 days and the mortality rate was 7.4 %. A significant higher proportion of victims aged 14-55 years were had less likelihood of death compared to those victims aged more than 55 years of age [Adjusted OR = 0.1 (95% CI: 0.01, 0.82)]. Conclusions: This study showed diverse injury characteristics and high morbidity and mortality among the victims attending Adult Emergency Department of Tikur Anbesa specialized hospital, Addis Ababa, Ethiopia. The findings reflect that road traffic accident is a major public health problem. Urgent road traffic accident preventive measures and prompt treatment of the victims are warranted in order to reduce morbidity and mortality among the victims. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=road%20traffic%20accident" title="road traffic accident">road traffic accident</a>, <a href="https://publications.waset.org/abstracts/search?q=injury%20characteristics" title=" injury characteristics"> injury characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=outcome" title=" outcome"> outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=Tikur%20Anbesa%20specialized%20hospital" title=" Tikur Anbesa specialized hospital"> Tikur Anbesa specialized hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=Addis%20Ababa" title=" Addis Ababa"> Addis Ababa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/22194/injury-characteristics-and-outcome-of-road-traffic-accident-among-victims-at-adult-emergency-department-of-tikur-anbesa-specialized-hospital-addis-ababa-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22194.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">384</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">12704</span> Hamlet as the Predecessor of Existentialism - A Study of Quintessential Expression of Existential Pondering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phani%20Kiran">Phani Kiran</a>, <a href="https://publications.waset.org/abstracts/search?q=Prabodha%20Manas%20Yarlagadda"> Prabodha Manas Yarlagadda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper attempts to treat Shakespeare’s tragic hero, Hamlet as an existential hero who faces many dilemmas in the process of taking revenge for his father’s murder. Hamlet can be considered as a predecessor of existentialism, and Shakespeare, as a pioneer, focused on some serious existential issues in the play much before they were fully developed in 20th century. Hamlet's internal struggles reflect existential themes such as alienation, despair, and the quest for authenticity. Hamlet’s famous soliloquy, "To be, or not to be," is a quintessential expression of existential ponderings, contemplating the choice between life and death and the uncertainty of what lies beyond. Hamlet grapples with existential questions like the purpose and meaninglessness of life, the nature of morality, the inevitability of death, and the existence of an afterlife. He doubts the authenticity of appearance and the reliability of his own perceptions, highlighting the inherent ambiguity and uncertainty of existence. Overall, "Hamlet" aligns with existential philosophy by exploring the complexities of human existence, the search for meaning, and the individual's struggle to find their place in an inherently uncertain and perplexing world. The character of Hamlet and the play's exploration of existential themes continue to resonate with audiences and provoke contemplation on the nature of life and the human experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=to%20be%20or%20not%20to%20be" title="to be or not to be">to be or not to be</a>, <a href="https://publications.waset.org/abstracts/search?q=death" title=" death"> death</a>, <a href="https://publications.waset.org/abstracts/search?q=dilemmas" title=" dilemmas"> dilemmas</a>, <a href="https://publications.waset.org/abstracts/search?q=illusion%20and%20reality" title=" illusion and reality"> illusion and reality</a> </p> <a href="https://publications.waset.org/abstracts/168795/hamlet-as-the-predecessor-of-existentialism-a-study-of-quintessential-expression-of-existential-pondering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168795.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">67</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">12703</span> Non-Adiabatic Silica Microfibre Sensor for BOD/COD Ratio Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20Chong">S.

BOD and COD are two main parameters to justify quality of wastewater. A ratio, BOD:COD can usually be established between the two analytical methods once COD and BOD value has been gathered. This ratio plays a vital role to determine appropriate strategy in wastewater treatment. A non-adiabatic microfiber sensor was formed by tapering the SMF to generate evanescent field where sensitive to perturbation of sensing medium. Because difference ratio BOD and COD contain in solution, this may induced changes of effective refractive index between microfiber and sensing medium. Attenuation wavelength shift to right with 0.5 nm and 3.5 nm while BOD:COD equal to 0.09 and 0.18 respectively. Significance difference wavelength shift may relate with the biodegradability of analyte. This proposed sensor is compact, reliable and feasible to determine the BOD:COD. Further research and investigation should be proceeded to enhance sensitivity and precision of the sensor for several of wastewater online monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-adiabatic%20fiber%20sensor" title="non-adiabatic fiber sensor">non-adiabatic fiber sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20sensing" title=" environmental sensing"> environmental sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradability" title=" biodegradability"> biodegradability</a>, <a href="https://publications.waset.org/abstracts/search?q=evanescent%20field" title=" evanescent field"> evanescent field</a> </p> <a href="https://publications.waset.org/abstracts/11703/non-adiabatic-silica-microfibre-sensor-for-bodcod-ratio-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11703.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">661</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">12702</span> Numerical Simulation of the Dynamic Behavior of a LaNi5 Water Pumping System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Miled%20Amel">Miled Amel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Maad%20Hatem"> Ben Maad Hatem</a>, <a href="https://publications.waset.org/abstracts/search?q=Askri%20Faouzi"> Askri Faouzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Nasrallah%20Sassi"> Ben Nasrallah Sassi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Metal hydride water pumping system uses hydrogen as working fluid to pump water for low head and high discharge. The principal operation of this pump is based on the desorption of hydrogen at high pressure and its absorption at low pressure by a metal hydride. This work is devoted to study a concept of the dynamic behavior of a metal hydride pump using unsteady model and LaNi5 as hydriding alloy. This study shows that with MHP, it is possible to pump 340l/kg-cycle of water in 15 000s using 1 Kg of LaNi5 at a desorption temperature of 360 K, a pumping head equal to 5 m and a desorption gear ratio equal to 33. This study reveals also that the error given by the steady model, using LaNi5 is about 2%.A dimensional mathematical model and the governing equations of the pump were presented to predict the coupled heat and mass transfer within the MHP. Then, a numerical simulation is carried out to present the time evolution of the specific water discharge and to test the effect of different parameters (desorption temperature, absorption temperature, desorption gear ratio) on the performance of the water pumping system (specific water discharge, pumping efficiency and pumping time). In addition, a comparison between results obtained with steady and unsteady model is performed with different hydride mass. Finally, a geometric configuration of the reactor is simulated to optimize the pumping time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20behavior" title="dynamic behavior">dynamic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=LaNi5" title=" LaNi5"> LaNi5</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20of%20water%20pumping%20system" title=" performance of water pumping system"> performance of water pumping system</a>, <a href="https://publications.waset.org/abstracts/search?q=unsteady%20model" title=" unsteady model"> unsteady model</a> </p> <a href="https://publications.waset.org/abstracts/69344/numerical-simulation-of-the-dynamic-behavior-of-a-lani5-water-pumping-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69344.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">205</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">12701</span> Incidence and Predictors of Mortality Among HIV Positive Children on Art in Public Hospitals of Harer Town, Enrolled From 2011 to 2021</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getahun%20Nigusie">Getahun Nigusie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background; antiretroviral treatment reduce HIV-related morbidity, and prolonged survival of patients however, there is lack of up-to-date information concerning the treatment long term effect on the survival of HIV positive children especially in the study area. Objective: To assess incidence and predictors of mortality among HIV positive children on ART in public hospitals of Harer town who were enrolled from 2011 to 2021. Methodology: Institution based retrospective cohort study was conducted among 429 HIV positive children enrolled in ART clinic from January 1st 2011 to December30th 2021. Data were collected from medical cards by using a data extraction form, Descriptive analyses were used to Summarized the results, and life table was used to estimate survival probability at specific point of time after introduction of ART. Kaplan Meier survival curve together with log rank test was used to compare survival between different categories of covariates, and Multivariate Cox-proportional hazard regression model was used to estimate adjusted Hazard rate. Variables with p-values ≤0.25 in bivariable analysis were candidates to the multivariable analysis. Finally, variables with p-values < 0.05 were considered as significant variables. Results: The study participants had followed for a total of 2549.6 child-years (30596 child months) with an overall mortality rate of 1.5 (95% CI: 1.1, 2.04) per 100 child-years. Their median survival time was 112 months (95% CI: 101–117). There were 38 children with unknown outcome, 39 deaths, and 55 children transfer out to different facility. The overall survival at 6, 12, 24, 48 months were 98%, 96%, 95%, 94% respectively. being in WHO clinical Stage four (AHR=4.55, 95% CI:1.36, 15.24), having anemia(AHR=2.56, 95% CI:1.11, 5.93), baseline low absolute CD4 count (AHR=2.95, 95% CI: 1.22, 7.12), stunting (AHR=4.1, 95% CI: 1.11, 15.42), wasting (AHR=4.93, 95% CI: 1.31, 18.76), poor adherence to treatment (AHR=3.37, 95% CI: 1.25, 9.11), having TB infection at enrollment (AHR=3.26, 95% CI: 1.25, 8.49),and no history of change their regimen(AHR=7.1, 95% CI: 2.74, 18.24), were independent predictors of death. Conclusion: more than half of death occurs within 2 years. Prevalent tuberculosis, anemia, wasting, and stunting nutritional status, socioeconomic factors, and baseline opportunistic infection were independent predictors of death. Increasing early screening and managing those predictors are required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20immunodeficiency%20virus-positive%20children" title="human immunodeficiency virus-positive children">human immunodeficiency virus-positive children</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-retroviral%20therapy" title=" anti-retroviral therapy"> anti-retroviral therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/189562/incidence-and-predictors-of-mortality-among-hiv-positive-children-on-art-in-public-hospitals-of-harer-town-enrolled-from-2011-to-2021" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189562.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">22</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">12700</span> Determination of Community Based Reference Interval of Aspartate Aminotransferase to Platelet Ratio Index (APRI) among Healthy Populations in Mekelle City Tigray, Northern Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Belay%20Kassahun">Getachew Belay Kassahun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Aspartate aminotransferase to Platelet Ratio Index (APRI) currently becomes a biomarker for screening liver fibrosis since liver biopsy procedure is invasive and variation in pathological interpretation. Clinical Laboratory Standard Institute recommends establishing age, sex and environment specific reference interval for biomarkers in a homogenous population. The current study was aimed to derive community based reference interval of APRI aged between 12 and 60 years old in Mekelle city Tigrai, Northern Ethiopia. Method: Six hundred eighty eight study participants were collected from three districts in Mekelle city. The 3 districts were selected through random sampling technique and sample size to kebelles (small administration) were distributed proportional to household number in each district. Lottery method was used at household level if more than 2 study participants to each age partition were found. A community based cross sectional in a total of 534 study participants, 264 male and 270 females, were included in the final laboratory and data analysis but around 154 study participants were excluded through exclusion criteria. Aspartate aminotransferase was analyzed through Biosystem chemistry analyzer and Sysmix machine was used to analyze platelet. Man Whitney U test non parametric stastical tool was used to appreciate stastical difference among gender after excluding the outliers through Box and Whisker. Result: The study appreciated stastical difference among gender for APRI reference interval. The combined, male and female reference interval in the current study was 0.098-0.390, 0.133-0.428 and 0.090-0.319 respectively. The upper and lower reference interval of males was higher than females in all age partition and there was no stastical difference (p-value (<0.05)) between age partition. Conclusion: The current study showed using sex specific reference interval is significant to APRI biomarker in clinical practice for result interpretation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reference%20interval" title="reference interval">reference interval</a>, <a href="https://publications.waset.org/abstracts/search?q=aspartate%20aminotransferase%20to%20platelet%20ratio%20Index" title=" aspartate aminotransferase to platelet ratio Index"> aspartate aminotransferase to platelet ratio Index</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=tigray" title=" tigray"> tigray</a> </p> <a href="https://publications.waset.org/abstracts/167950/determination-of-community-based-reference-interval-of-aspartate-aminotransferase-to-platelet-ratio-index-apri-among-healthy-populations-in-mekelle-city-tigray-northern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167950.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">114</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">12699</span> Heat and Humidity Induced Plastic Changes in Body Lipids and Starvation Resistance in the Tropical Zaprionus indianus of Wet-Dry Seasons </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20N.%20Girish">T.

Accordingly, we analyzed such plastic changes in Zaprionus indianus flies reared under wet or dry season-specific conditions; and also after adult acclimation at 32℃ for 1 to 6 days; and to low (40% RH) or high (70% RH) humidity. Both thermal or humidity acclimation revealed significant accumulation of body lipids for wet season flies but low humidity acclimation did not change the level of body lipids in dry season flies. Developmental and adult acclimation showed sex specific differences i.e., starvation resistance and body lipids were higher in the males of dry season but in females of wet season. We found seasonal and sex specific differences in the relative level for body lipids at death; and in the rates of accumulation or utilization of energy metabolites (body lipids, carbohydrates and proteins). Body lipids constitute the preferred energy source under starvation for flies of both the seasons. However, utilization of carbohydrates (~20% to 30%) and proteins (~20% to 25%) was evident only in dry season flies. Higher starvation resistance after thermal or humidity acclimation is achieved by increased accumulation of lipids. Adult acclimation of wet or dry season flies revealed plastic changes in mean daily fecundity despite reduction in fecundity under starvation. Thus, thermal or humidity induced plastic responses in body lipids support starvation resistance under wet or dry seasons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20or%20humidity%20acclimation" title="heat or humidity acclimation">heat or humidity acclimation</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20changes%20in%20body%20lipids%20and%20starvation%20resistance" title=" plastic changes in body lipids and starvation resistance"> plastic changes in body lipids and starvation resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=tropical%20drosophilid" title=" tropical drosophilid"> tropical drosophilid</a>, <a href="https://publications.waset.org/abstracts/search?q=Wet-%20or%20Dry%20seasons" title=" Wet- or Dry seasons"> Wet- or Dry seasons</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaprionus%20indianus" title=" Zaprionus indianus"> Zaprionus indianus</a> </p> <a href="https://publications.waset.org/abstracts/89400/heat-and-humidity-induced-plastic-changes-in-body-lipids-and-starvation-resistance-in-the-tropical-zaprionus-indianus-of-wet-dry-seasons" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89400.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">153</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">12698</span> Evaluation Performance of Transport Vehicle on Different Surfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Abbas%20Jebur">Hussein Abbas Jebur</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasir%20Abd%20Ulrazzaq"> Yasir Abd Ulrazzaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was carried out at the farm of El-Gemmaiza Agriculture Research Station, El-Garbia Governorate Egypt, to determine the performance characteristics of an agricultural transport.

The objective of this study was to assess whether SARS-CoV-2 viral load in wastewater could serve as a predictor for forecasting COVID-19 cases, hospitalization cases, and death cases using copula-based time series modeling. SARS-CoV-2 RNA load in raw wastewater in Chesapeake VA was measured using the RT-qPCR method. Gaussian copula time series marginal regression model, incorporating an autoregressive moving average model and the copula function, served as a forecasting model. COVID-19 cases were correlated with wastewater viral load, hospitalization cases, and death cases. The forecasted trend of COVID-19 cases closely paralleled one of the reported cases, with over 90% of the forecasted COVID-19 cases falling within the 99% confidence interval of the reported cases.

The variables; market capitalization ratio, turnover ratio and liquidity proxies by the ratio of market capitalization to gross domestic product were sourced and computed from the Nigerian stock exchange fact books and the CBN statistical bulletin of the Central Bank of Nigeria. The variables were tested and found stationary and cointregrated using the augumented Dickey Fuller unit root test and the Johnson cointegration test respectively. The dynamic behavior of the stock market development model was verified using the error correction model. The result shows that about 0.4l percent of the short run deviation is corrected every year and also reveals that market capitalization ratio and market liquidity are positive and significant function of economic growth. In other words market capitalization ratio and liquidity positively and significantly impact economic growth. Market development variables such as turnover ratio and market restriction can exert positive but insignificant impact on the growth of the economy suggesting that securities transaction relative to the size of the securities market are not high enough to significantly engender economic growth in Nigeria. In the light of this, the researchers recommend that the regulatory body as well as the government, should provide a conducive environment capable of encouraging the growth and development of the stock market. This if well articulated will enhance the market turnover and the growth of the economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=market%20capitalization%20ratio" title="market capitalization ratio">market capitalization ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=turnover%20ratio" title=" turnover ratio"> turnover ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=liquidity" title=" liquidity"> liquidity</a>, <a href="https://publications.waset.org/abstracts/search?q=unit%20root%20test" title=" unit root test"> unit root test</a>, <a href="https://publications.waset.org/abstracts/search?q=cointegration" title=" cointegration"> cointegration</a> </p> <a href="https://publications.waset.org/abstracts/52846/stock-market-development-and-the-growth-of-nigerian-economy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52846.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">341</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">12695</span> Bringing the Confidence Intervals into Choropleth Mortality Map: An Example of Tainan, Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tzu-Jung%20Tseng">Tzu-Jung Tseng</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Hsuen%20Han"> Pei-Hsuen Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsung-Hsueh%20Lu"> Tsung-Hsueh Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Choropleth mortality map is commonly used to identify areas with higher mortality risk. However, the use of choropleth map alone might result in the misinterpretation of differences in mortality rates between areas. Two areas with different color shades might not actually have a significant difference in mortality rates. The mortality rates estimated for an area with a small population would be less stable. We suggest of bringing the 95% confidence intervals (CI) into the choropleth mortality map to help users interpret the areal mortality rate difference more properly. Method: In the first choropleth mortality map, we used only three color to indicate standardized mortality ratio (SMR) for each district in Tainan, Taiwan. The red color denotes that the SMR of that district was significantly higher than the Tainan average; on the contrary, the green color suggests that the SMR of that district was significantly lower than the Tainan average. The yellow color indicates that the SMR of that district was not statistically significantly different from the Tainan average. In the second choropleth mortality map, we used traditional sequential color scheme (color ramp) for different SMR in 37 districts in Tainan City with bar chart of each SMR with 95% CI in which the users could examine if the line of 95% CI of SMR of two districts overlapped (nonsignificant difference). Results: The all-causes SMR of each district in Tainan for 2008 to 2013 ranged from 0.77 (95% CI 0.75 to 0.80) in East District to 1.39 Beimen (95% CI 1.25 to 1.52). In the first choropleth mortality map, only 16 of 37 districts had red color and 8 districts had green color. For different causes of death, the number of districts with red color differed. In the first choropleth mortality map we added a bar chart with line of 95% CI of SMR in each district, in which the users could visualize the SMR differences between districts. Conclusion: Through the use of 95% CI the users could interpret the aral mortality differences more properly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=choropleth%20map" title="choropleth map">choropleth map</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20area%20variation" title=" small area variation"> small area variation</a>, <a href="https://publications.waset.org/abstracts/search?q=standardized%20mortality%20ratio%20%28SMR%29" title=" standardized mortality ratio (SMR)"> standardized mortality ratio (SMR)</a>, <a href="https://publications.waset.org/abstracts/search?q=Taiwan" title=" Taiwan"> Taiwan</a> </p> <a href="https://publications.waset.org/abstracts/61883/bringing-the-confidence-intervals-into-choropleth-mortality-map-an-example-of-tainan-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61883.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">325</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">12694</span> hsa-miR-1204 and hsa-miR-639 Prominent Role in Tamoxifen's Molecular Mechanisms on the EMT Phenomenon in Breast Cancer Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Taghavi">Mahsa Taghavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the treatment of breast cancer, tamoxifen is a regularly prescribed medication. The effect of tamoxifen on breast cancer patients' EMT pathways was studied. In this study to see if it had any effect on the cancer cells' resistance to tamoxifen and to look for specific miRNAs associated with EMT. In this work, we used continuous and integrated bioinformatics analysis to choose the optimal GEO datasets. Once we had sorted the gene expression profile, we looked at the mechanism of signaling, the ontology of genes, and the protein interaction of each gene. In the end, we used the GEPIA database to confirm the candidate genes. after that, I investigated critical miRNAs related to candidate genes. There were two gene expression profiles that were categorized into two distinct groups. Using the expression profile of genes that were lowered in the EMT pathway, the first group was examined. The second group represented the polar opposite of the first. A total of 253 genes from the first group and 302 genes from the second group were found to be common. Several genes in the first category were linked to cell death, focal adhesion, and cellular aging. Two genes in the second group were linked to cell death, focal adhesion, and cellular aging. distinct cell cycle stages were observed. Finally, proteins such as MYLK, SOCS3, and STAT5B from the first group and BIRC5, PLK1, and RAPGAP1 from the second group were selected as potential candidates linked to tamoxifen's influence on the EMT pathway. hsa-miR-1204 and hsa-miR-639 have a very close relationship with the candidates genes according to the node degrees and betweenness index. With this, the action of tamoxifen on the EMT pathway was better understood. It's important to learn more about how tamoxifen's target genes and proteins work so that we can better understand the drug. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tamoxifen" title="tamoxifen">tamoxifen</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatics%20analysis" title=" bioinformatics analysis"> bioinformatics analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=EMT" title=" EMT"> EMT</a>, <a href="https://publications.waset.org/abstracts/search?q=miRNAs" title=" miRNAs"> miRNAs</a> </p> <a href="https://publications.waset.org/abstracts/149734/hsa-mir-1204-and-hsa-mir-639-prominent-role-in-tamoxifens-molecular-mechanisms-on-the-emt-phenomenon-in-breast-cancer-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149734.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">129</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">12693</span> Response of Summer Sesame to Irrigation Regimes and Nitrogen Levels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kalpana%20Jamdhade">Kalpana Jamdhade</a>, <a href="https://publications.waset.org/abstracts/search?q=Anita%20Chorey"> Anita Chorey</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharti%20Tijare"> Bharti Tijare</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20M.%20Bhale"> V.

The experiment was laid out in split plot Design in which three irrigation scheduling on the basis of IW/CPE ratio viz., irrigation at 0.6, 0.8 and 1.0 IW/CPE ratios (I1, I2 and I3, respectively) and one irrigation scheduling based on critical growth stages of sesame (I4), in main plot and three nitrogen levels 0, 30 and 60 kg N ha-1 (N0, N1 and N2, respectively) in subplot. The result showed that plant height, number of leaves plant-1, leaf area and dry matter accumulation were maximum in irrigation scheduling at 1.0 IW/CPE ratio, which significantly superior over 0.6 IW/CPE ratio and irrigation at critical growth stages but were statistically at par with irrigation at 0.8 IW/CPE ratio. Nitrogen levels, application of 60 kg N ha-1 was recorded significantly superior all growth parameters over treatment 30 kg N ha-1 and 0 kg N ha-1. In case of yield attributes viz., No. of capsules plant-1, Test wt., grain yield and Stalk yield (qha-1) were maximum in irrigation scheduling at 1.0 IW/CPE ratio and were significantly superior over 0.8 IW/CPE ratio, 0.6 IW/CPE ratio and irrigation at critical growth stages.

Starting from the economic balance sheet available under Solvency II for insurance and reinsurance undertakings, we assume that assets and liabilities follow a bivariate geometric Brownian motion (GBM). Then, using the results available under Margrabe's formula, we establish an analytical solution to calibrate the volatility of the asset-liability ratio. In such a way, we can estimate the probability of default and the probability of breaching the undertaking's Solvency Capital Requirement (SCR). Furthermore, since estimating the volatility of the Solvency Ratio became crucial for insurers in light of the financial crises featured in the last decades, we introduce a novel measure that we call Resiliency Ratio. The Resiliency Ratio can be used, in addition to the Solvency Ratio, to evaluate the insurance industry's resilience in case of adverse scenarios. Finally, we introduce a simplified stress test tool to evaluate the economic balance sheet under stressed conditions. The model we propose is featured by analytical tractability and fast calibration procedure where only the disclosed data available under the Solvency II public reporting are needed for the calibration. Using the data published regularly by the European Insurance and Occupational Pensions Authority (EIOPA) in an aggregated form by country, an empirical analysis has been performed to calibrate the model and provide the related results at the country level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solvency%20II" title="Solvency II">Solvency II</a>, <a href="https://publications.waset.org/abstracts/search?q=solvency%20ratio" title=" solvency ratio"> solvency ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility%20of%20the%20asset-liability%20ratio" title=" volatility of the asset-liability ratio"> volatility of the asset-liability ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20default" title=" probability of default"> probability of default</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20to%20breach%20the%20SCR" title=" probability to breach the SCR"> probability to breach the SCR</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience%20ratio" title=" resilience ratio"> resilience ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20test" title=" stress test"> stress test</a> </p> <a href="https://publications.waset.org/abstracts/163459/assessing-the-resilience-of-the-insurance-industry-under-solvency-ii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163459.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">81</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">12691</span> Experimental Assessment of Artificial Flavors Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Unis">M.

Investigation of kinetics of the reaction indicated that the low of molar ratio is favored for esterification reaction, this is due to the reaction is catalyzed by acid. The maximum conversion, approximately 60.6% was obtained at 80°C for molar ratio of 1:3 acid : alcohol. It was found that increasing temperature of the reaction, increases the rate constant and conversion at a certain mole ratio, that is due to the esterification is exothermic. The homogenous reaction has been described with simple power-law model. The chemical equilibrium combustion calculated from the kinetic model in agreement with the measured chemical equilibrium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20flavors" title="artificial flavors">artificial flavors</a>, <a href="https://publications.waset.org/abstracts/search?q=esterification" title=" esterification"> esterification</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20equilibria" title=" chemical equilibria"> chemical equilibria</a>, <a href="https://publications.waset.org/abstracts/search?q=isothermal" title=" isothermal "> isothermal </a> </p> <a href="https://publications.waset.org/abstracts/18398/experimental-assessment-of-artificial-flavors-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18398.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">335</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">12690</span> Descriptive Epidemiology of Mortality in Certain Species of Captive Deer in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Musadiq%20Idris">Musadiq Idris</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Ali"> Sajjad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20A.%20Khaliq"> Syed A.

The submissions included temporal distribution from Government wildlife captive farms, zoo, and private ownerships, over a three year period (2007-2009). The most common cause of death was found to be trauma (20.27%), followed by parasitic diseases (15.67%), bacterial diseases (11.98%), stillbirths (9.21%), snakebites (2.76%), gut affections (2.30%), neoplasia (1.38%) and starvation (0.92%). The exact cause of death could not be determined in 77 of 217 animals. Pneumonia (8.29%) and tuberculosis (3.69%) were the most common bacterial diseases. Analyses for parasitic infestation revealed tapeworms to be highest (11.05%), followed by roundworms (8.29%) and hemoparasitism (5.07%) (babesiosis and theileriosis). The mortality rate in young ungulates was lower as compared to adults (32.26% and 67.74%). Gender wise data presented higher mortality in females (55.30%) compared to males (44.70%). In conclusion, highest mortality factor in captive ungulates was trauma, followed by parasitic and bacterial infestations/infections of tapeworms and pneumonia, respectively. Furthermore, necropsies provided substantial information on etiology of death and other related epidemiological aspects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age" title="age">age</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=ungulates" title=" ungulates"> ungulates</a> </p> <a href="https://publications.waset.org/abstracts/24506/descriptive-epidemiology-of-mortality-in-certain-species-of-captive-deer-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24506.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">471</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">12689</span> Analysis of Reinforced Granular Pile in Soft Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Nitesh">G.

Objective: The aim of this study is to assess the incidence and predictors of mortality among HIV positive children on antiretroviral therapy (ART) in public hospitals of Harer town who were enrolled from 2011 to 2021. Methodology: Institution based retrospective cohort study was conducted among 429 HIV positive children enrolled in ART clinic from January 1st 2011 to December30th 2021. Data were collected from medical cards by using a data extraction form, Descriptive analyses were used to Summarized the results, and life table was used to estimate survival probability at specific point of time after introduction of ART. Kaplan Meier survival curve together with log rank test was used to compare survival between different categories of covariates, and Multivariate Cox-proportional hazard regression model was used to estimate adjusted Hazard rate. Variables with p-values ≤0.25 in bivariable analysis were candidates to the multivariable analysis. Finally, variables with p-values < 0.05 were considered as significant variables. Results: The study participants had followed for a total of 2549.6 child-years (30596 child months) with an overall mortality rate of 1.5 (95% CI: 1.1, 2.04) per 100 child-years. Their median survival time was 112 months (95% CI: 101–117). There were 38 children with unknown outcome, 39 deaths, and 55 children transfer out to different facility. The overall survival at 6, 12, 24, 48 months were 98%, 96%, 95%, 94% respectively. being in WHO clinical Stage four (AHR=4.55, 95% CI:1.36, 15.24), having anemia(AHR=2.56, 95% CI:1.11, 5.93), baseline low absolute CD4 count (AHR=2.95, 95% CI: 1.22, 7.12), stunting (AHR=4.1, 95% CI: 1.11, 15.42), wasting (AHR=4.93, 95% CI: 1.31, 18.76), poor adherence to treatment (AHR=3.37, 95% CI: 1.25, 9.11), having TB infection at enrollment (AHR=3.26, 95% CI: 1.25, 8.49),and no history of change their regimen(AHR=7.1, 95% CI: 2.74, 18.24), were independent predictors of death. Conclusion: more than half of death occurs within 2 years. Prevalent tuberculosis, anemia, wasting, and stunting nutritional status, socioeconomic factors, and baseline opportunistic infection were independent predictors of death. Increasing early screening and managing those predictors are required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20immunodeficiency%20virus-positive%20children" title="human immunodeficiency virus-positive children">human immunodeficiency virus-positive children</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-retroviral%20therapy" title=" anti-retroviral therapy"> anti-retroviral therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/185290/assessment-of-incidence-and-predictors-of-mortality-among-hiv-positive-children-on-art-in-public-hospitals-of-harer-town-who-were-enrolled-from-2011-to-2021" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185290.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">49</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">12685</span> Improved Signal-To-Noise Ratio by the 3D-Functionalization of Fully Zwitterionic Surface Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20Van%20Andel">Esther Van Andel</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefanie%20C.%20Lange"> Stefanie C.

To improve the reliability of surface-based diagnostic tests, it is of crucial importance to diminish background signals that arise from the non-specific binding of biomolecules, a process called fouling. The aim is to create surfaces that repel all biomolecules except the molecule of interest. This can be achieved by incorporating antifouling protein repellent coatings in between the sensor surface and it’s recognition elements (e.g. antibodies, sugars, aptamers). Zwitterionic polymer brushes are considered excellent antifouling materials, however, to be able to bind the molecule of interest, the polymer brushes have to be functionalized and so far this was only achieved at the expense of either antifouling or binding capacity. To overcome this limitation, we combined both features into one single monomer: a zwitterionic sulfobetaine, ensuring antifouling capabilities, equipped with a clickable azide moiety which allows for further functionalization. By copolymerizing this monomer together with a standard sulfobetaine, the number of azides (and with that the number of recognition elements) can be tuned depending on the application. First, the clickable azido-monomer was synthesized and characterized, followed by copolymerizing this monomer to yield functionalizable antifouling brushes. The brushes were fully characterized using surface characterization techniques like XPS, contact angle measurements, G-ATR-FTIR and XRR. As a proof of principle, the brushes were subsequently functionalized with biotin via strain-promoted alkyne azide click reactions, which yielded a fully zwitterionic biotin-containing 3D-functionalized coating. The sensing capacity was evaluated by reflectometry using avidin and fibrinogen containing protein solutions. The surfaces showed excellent antifouling properties as illustrated by the complete absence of non-specific fibrinogen binding, while at the same time clear responses were seen for the specific binding of avidin. A great increase in signal-to-noise ratio was observed, even when the amount of functional groups was lowered to 1%, compared to traditional modification of sulfobetaine brushes that rely on a 2D-approach in which only the top-layer can be functionalized. This study was performed on stoichiometric silicon nitride surfaces for future microring resonator based assays, however, this methodology can be transferred to other biosensor platforms which are currently being investigated. The approach presented herein enables a highly efficient strategy for selective binding with retained antifouling properties for improved signal-to-noise ratios in binding assays. The number of recognition units can be adjusted to a specific need, e.g. depending on the size of the analyte to be bound, widening the scope of these functionalizable surface coatings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifouling" title="antifouling">antifouling</a>, <a href="https://publications.waset.org/abstracts/search?q=signal-to-noise%20ratio" title=" signal-to-noise ratio"> signal-to-noise ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20functionalization" title=" surface functionalization"> surface functionalization</a>, <a href="https://publications.waset.org/abstracts/search?q=zwitterionic%20polymer%20brushes" title=" zwitterionic polymer brushes"> zwitterionic polymer brushes</a> </p> <a href="https://publications.waset.org/abstracts/62532/improved-signal-to-noise-ratio-by-the-3d-functionalization-of-fully-zwitterionic-surface-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62532.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">306</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">12684</span> Improvement of Egyptian Vacuum Distillates by Solvent Dewaxing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehssan%20M.%20R.%20Nassef">Ehssan M.

The present work deals with studying solvent dewaxing system which have been developed to give better dewaxing performance with respect to the important factors in the choice of solvents which are good solubility of oil in the solvent and low solubility of wax in the solvent. In this study, solvent dewaxing process using Methyl Ethyl Ketone (MEK) and toluene are used for Egyptian vacuum distillates using two types of distillates. The effect of varying the composition of(MEK to toluene) on the percent yield of the oil, percent of wax, pour point, refractive index at 20 and 70°C, viscosity at 40 and 100°C, viscosity index and specific gravity of the oil produced for the two types of distillates (I & II) were evaluated. In the present study, the operating conditions of solvent dewaxing using MEK toluene mixture achieved the best pour point at -15°C for distillate I at (1:1) solvent composition mixture. At the same ratio of MEK to toluene the best specific gravity of oil produced changed from 0.871 to 0.8802, with refractive index of 1.84. Percent yield of 65% for oil was obtained. The results for distillate II, of higher specific gravity, are comparatively higher than those for distillate I. The effect of temperature was also investigated and the best temperature was -20°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dewaxing" title="dewaxing">dewaxing</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20dewaxing" title=" solvent dewaxing"> solvent dewaxing</a>, <a href="https://publications.waset.org/abstracts/search?q=pour%20point" title=" pour point"> pour point</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricating%20oil%20production" title=" lubricating oil production"> lubricating oil production</a>, <a href="https://publications.waset.org/abstracts/search?q=wax" title=" wax "> wax </a> </p> <a href="https://publications.waset.org/abstracts/22202/improvement-of-egyptian-vacuum-distillates-by-solvent-dewaxing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22202.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">532</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">12683</span> Contribution of Crime Scene and Autopsy Investigation to the Solving of the Case in the Case of Death as a Result of Self-Harm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murat%20Mert">Murat Mert</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ozer"> Yusuf Ozer</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Kolay"> Fatih Kolay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Behaviour of giving harm to the body in literature has been named as “self-injury”, “self-mutilation” ve “self-harm”. “Self-injury”, or “self-mutilation” is generally used for the same meaning and mentioned as an action which is committed to the body itself directly.

The synthesized catalysts were characterized by transmission electron microscopy (TEM), temperature programmed desorption, reduction, oxidation and pulse chemisorption (TPDRO), and surface area determination was also performed. All catalysts were tested with respect to the hydrogenation of CO<sub>2</sub> to methanol in microactivity fixed-bed reactor at 250<sup>o</sup>C, 2.25 MPa, and H<sub>2</sub>/CO<sub>2</sub> ratio of 3. The results demonstrate that the catalytic structure, activity, and methanol selectivity was strongly affected by the ratio between Cu: Zn, Where higher catalytic activity of 14 % and methanol selectivity of 92 % was obtained over Cu/ZnO-SBA-15 catalyst with Cu:Zn ratio of 7:3 wt. %. Comparing with the single catalyst, the synergetic between Cu and Zn provides additional active sites to adsorb more H<sub>2</sub> and CO<sub>2</sub> and accelerate the CO<sub>2</sub> conversion, resulting in higher methanol production under mild reaction conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogenation%20of%20carbon%20dioxide" title="hydrogenation of carbon dioxide">hydrogenation of carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol%20synthesis" title=" methanol synthesis"> methanol synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu%2FZnO-based%20catalyst" title=" Cu/ZnO-based catalyst"> Cu/ZnO-based catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=mesoporous%20silica%20%28SBA-15%29" title=" mesoporous silica (SBA-15)"> mesoporous silica (SBA-15)</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20ratio" title=" metal ratio"> metal ratio</a> </p> <a href="https://publications.waset.org/abstracts/59554/hydrogenation-of-co2-to-methanol-over-copper-zinc-oxide-based-catalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59554.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">250</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">12681</span> Investors' Ratio Analysis and the Profitability of Listed Firms: Evidence from Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abisola%20Akinola">Abisola Akinola</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinsulere%20Femi"> Akinsulere Femi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stock market has continually been a source of economic development in most developing countries. This study examined the relationship between investors’ ratio analysis and profitability of quoted companies in Nigeria using secondary data obtained from the annual reports of forty-two (42) companies. The study employed the multiple regression technique to analyze the relationship between investors’ ratio analysis (measured by dividend per share and earning per share) and profitability (measured by the return on equity). The results from the analysis show that investors’ ratio analysis, when measured by earnings per share, have a positive and significant impact on profitability. However, the study noted that investors’ ratio analysis, when measured by dividend per share, tend to have a positive impact on profitability but it is statistically insignificant. By implication, investors and other stakeholders that are interested in investing in stocks can predict the earning capacity of listed firms in the stock market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dividend%20per%20share" title="dividend per share">dividend per share</a>, <a href="https://publications.waset.org/abstracts/search?q=earnings%20per%20share" title=" earnings per share"> earnings per share</a>, <a href="https://publications.waset.org/abstracts/search?q=profitability" title=" profitability"> profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=return%20on%20equity" title=" return on equity"> return on equity</a> </p> <a href="https://publications.waset.org/abstracts/109160/investors-ratio-analysis-and-the-profitability-of-listed-firms-evidence-from-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109160.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">137</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">12680</span> Reuse of Municipal Solid Waste Incinerator Fly Ash for the Synthesis of Zeolite: Effects of Different Operation Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyh-Cherng%20Chen">Jyh-Cherng Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Jie%20Lin"> Yi-Jie Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study tries to reuse the fly ash of municipal solid waste incinerator (MSWI) for the synthesis of zeolites. The fly ashes were treated with NaOH alkali fusion at different temperatures for 40 mins and then synthesized the zeolites with hydrothermal method at 105oC for different operation times. The effects of different operation conditions and the optimum synthesis parameters were explored. The specific surface area, surface morphology, species identification, adsorption capacity, and the reuse potentials of the synthesized zeolites were analyzed and evaluated. Experimental results showed that the optimum operation conditions for the synthesis of zeolite from the mixed fly ash were Si/Al=20, alkali/ash=1.5, alkali fusion reaction with NaOH at 800oC for 40 mins, hydrolysis with L/S=200 at 105oC for 24 hr, and hydrothermal synthesis at 105oC for 48 hr. The largest specific surface area of synthesized zeolite could be increased to 943.05m2/g. The influence of different operation parameters on the synthesis of zeolite from mixed fly ash followed the sequence of Si/Al > hydrolysis L/S> hydrothermal time > alkali fusion temperature > alkali/ash ratio. The XRD patterns of synthesized zeolites were identified to be similar with the ZSM-23 zeolite. The adsorption capacities of synthesized zeolite for pollutants were increased as rising the specific surface area of synthesized zeolite. In summary, MSWI fly ash can be treated and reused to synthesize the zeolite with high specific surface area by the alkali fusion and hydrothermal method. The zeolite can be reuse for the adsorption of various pollutants. They have great potential for development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkali%20fusion" title="alkali fusion">alkali fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal" title=" hydrothermal"> hydrothermal</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=zeolite" title=" zeolite"> zeolite</a> </p> <a href="https://publications.waset.org/abstracts/95849/reuse-of-municipal-solid-waste-incinerator-fly-ash-for-the-synthesis-of-zeolite-effects-of-different-operation-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95849.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">174</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">12679</span> Stability Optimization of NABH₄ via PH and H₂O:NABH₄ Ratios for Large Scale Hydrogen Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parth%20Mehta">Parth Mehta</a>, <a href="https://publications.waset.org/abstracts/search?q=Vedasri%20Bai%20Khavala"> Vedasri Bai Khavala</a>, <a href="https://publications.waset.org/abstracts/search?q=Prabhu%20Rajagopal"> Prabhu Rajagopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tiju%20Thomas"> Tiju Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is an increasing need for alternative clean fuels, and hydrogen (H₂) has long been considered a promising solution with a high calorific value (142MJ/kg). However, the storage of H₂ and expensive processes for its generation have hindered its usage. Sodium borohydride (NaBH₄) can potentially be used as an economically viable means of H₂ storage. Thus far, there have been attempts to optimize the life of NaBH₄ (half-life) in aqueous media by stabilizing it with sodium hydroxide (NaOH) for various pH values. Other reports have shown that H₂ yield and reaction kinetics remained constant for all ratios of H₂O to NaBH₄ > 30:1, without any acidic catalysts. Here we highlight the importance of pH and H₂O: NaBH₄ ratio (80:1, 40:1, 20:1 and 10:1 by weight), for NaBH₄ stabilization (half-life reaction time at room temperature) and corrosion minimization of H₂ reactor components. It is interesting to observe that at any particular pH>10 (e.g., pH = 10, 11 and 12), the H₂O: NaBH₄ ratio does not have the expected linear dependence with stability. On the contrary, high stability was observed at the ratio of 10:1 H₂O: NaBH₄ across all pH>10. When the H₂O: NaBH₄ ratio is increased from 10:1 to 20:1 and beyond (till 80:1), constant stability (% degradation) is observed with respect to time. For practical usage (consumption within 6 hours of making NaBH₄ solution), 15% degradation at pH 11 and NaBH₄: H₂O ratio of 10:1 is recommended. Increasing this ratio demands higher NaOH concentration at the same pH, thus requiring a higher concentration or volume of acid (e.g., HCl) for H₂ generation. The reactions are done with tap water to render the results useful from an industrial standpoint. The observed stability regimes are rationalized based on complexes associated with NaBH₄ when solvated in water, which depend sensitively on both pH and NaBH₄: H₂O ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title="hydrogen">hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20borohydride" title=" sodium borohydride"> sodium borohydride</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20optimization" title=" stability optimization"> stability optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=H%E2%82%82O%3ANaBH%E2%82%84%20ratio" title=" H₂O:NaBH₄ ratio"> H₂O:NaBH₄ ratio</a> </p> <a href="https://publications.waset.org/abstracts/151526/stability-optimization-of-nabh4-via-ph-and-h2onabh4-ratios-for-large-scale-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151526.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">120</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">12678</span> Study of Aerosol Deposition and Shielding Effects on Fluorescent Imaging Quantitative Evaluation in Protective Equipment Validation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shinhao%20Yang">Shinhao Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsiao-Chien%20Huang"> Hsiao-Chien Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chin-Hsiang%20Luo"> Chin-Hsiang Luo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The leakage of protective clothing is an important issue in the occupational health field. There is no quantitative method for measuring the leakage of personal protective equipment. This work aims to measure the quantitative leakage of the personal protective equipment by using the fluorochrome aerosol tracer. The fluorescent aerosols were employed as airborne particulates in a controlled chamber with ultraviolet (UV) light-detectable stickers. After an exposure-and-leakage test, the protective equipment was removed and photographed with UV-scanning to evaluate areas, color depth ratio, and aerosol deposition and shielding effects of the areas where fluorescent aerosols had adhered to the body through the protective equipment. Thus, this work built a calculation software for quantitative leakage ratio of protective clothing based on fluorescent illumination depth/aerosol concentration ratio, illumination/Fa ratio, aerosol deposition and shielding effects, and the leakage area ratio on the segmentation. The results indicated that the two-repetition total leakage rate of the X, Y, and Z type protective clothing for subject T were about 3.05, 4.21, and 3.52 (mg/m2). For five-repetition, the leakage rate of T were about 4.12, 4.52, and 5.11 (mg/m2). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluorochrome" title="fluorochrome">fluorochrome</a>, <a href="https://publications.waset.org/abstracts/search?q=deposition" title=" deposition"> deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=shielding%20effects" title=" shielding effects"> shielding effects</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20image%20processing" title=" digital image processing"> digital image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=leakage%20ratio" title=" leakage ratio"> leakage ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20protective%20equipment" title=" personal protective equipment"> personal protective equipment</a> </p> <a href="https://publications.waset.org/abstracts/43218/study-of-aerosol-deposition-and-shielding-effects-on-fluorescent-imaging-quantitative-evaluation-in-protective-equipment-validation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43218.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">323</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">12677</span> Narratives and Meta-Narratives in the News of People Killed in 2022 Iranian Protests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Rezaei%20Samarin">Abbas Rezaei Samarin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In October 2022, protests began following the death of Mahsa Amini and were followed by the deaths of those arrested by Iran's morality police which Iran's official media and foreign Persian-language satellite channels presented to the audience different narratives of how they were killed. These two types of media produced two different and sometimes conflicting narratives when faced with the news of a certain person's death, and the conflict is found between the narratives in some cases. This study has focused on the semiotics of these narratives, the interpretation of discourses supporting the narratives, and finally, their analysis within the framework of narrative theories. In the present study, the researcher has used a qualitative approach and has concluded that the narrative of both types of media is structured around the functions of the existing and ideal political
