Batch equilibrium studies were carried out to optimize various parameters such as pH of metal ion solution, volume of sorbate, sorbent doze, and agitation speed and agitation time. Maximum sorption efficiency of mulberry leaves for As (III) and As (V) at optimum conditions were 2818 μg.g-1 and 4930 μg.g-1, respectively. The experimental data was a good fit to Freundlich and D-R adsorption isotherm. Energy of adsorption was found to be in the range of 3-6 KJ/mole suggesting the physical nature of process. Kinetic data followed the first order rate, Morris-Weber equations. Developed method was applied to remove arsenic from real water samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arsenic%20removal" title="arsenic removal">arsenic removal</a>, <a href="https://publications.waset.org/abstracts/search?q=mulberry" title=" mulberry"> mulberry</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20isotherms" title=" adsorption isotherms"> adsorption isotherms</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics%20of%20adsorption" title=" kinetics of adsorption"> kinetics of adsorption</a> </p> <a href="https://publications.waset.org/abstracts/5150/mulberry-leave-an-efficient-and-economical-adsorbent-for-remediation-of-arsenic-v-and-arsenic-iii-contaminated-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5150.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">275</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">73</span> Extraction of Polystyrene from Styrofoam Waste: Synthesis of Novel Chelating Resin for the Enrichment and Speciation of Cr(III)/Cr(vi) Ions in Industrial Effluents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20N.%20Siyal">Ali N.

The PS was functionalized with N, N- Bis(2-aminobenzylidene)benzene-1,2-diamine (ABA) ligand through an azo spacer. The resin was characterized by FT-IR spectroscopy and elemental analysis. The PS-N=N-ABA resin was used for the enrichment and speciation of Cr(III)/Cr(VI) ions and total Cr determination in aqueous samples by Flame Atomic Absorption Spectrometry (FAAS). The separation of Cr(III)/Cr(VI) ions was achieved at pH 2. The recovery of Cr(VI) ions was achieved ≥ 95.0% at optimum parameters: pH 2; resin amount 300 mg; flow rates 2.0 mL min-1 of solution and 2.0 mL min-1 of eluent (2.0 mol L-1 HNO3). Total Cr was determined by oxidation of Cr(III) to Cr(VI) ions using H2O2. The limit of detection (LOD) and quantification (LOQ) of Cr(VI) were found to be 0.40 and 1.20 μg L-1, respectively with preconcentration factor of 250. Total saturation and breakthrough capacitates of the resin for Cr(IV) ions were found to be 0.181 and 0.531 mmol g-1, respectively. The proposed method was successfully applied for the preconcentration/speciation of Cr(III)/Cr(VI) ions and determination of total Cr in industrial effluents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=styrofoam%20waste" title="styrofoam waste">styrofoam waste</a>, <a href="https://publications.waset.org/abstracts/search?q=polymeric%20resin" title=" polymeric resin"> polymeric resin</a>, <a href="https://publications.waset.org/abstracts/search?q=preconcentration" title=" preconcentration"> preconcentration</a>, <a href="https://publications.waset.org/abstracts/search?q=speciation" title=" speciation"> speciation</a>, <a href="https://publications.waset.org/abstracts/search?q=Cr%28III%29%2FCr%28VI%29%20ions" title=" Cr(III)/Cr(VI) ions"> Cr(III)/Cr(VI) ions</a>, <a href="https://publications.waset.org/abstracts/search?q=FAAS" title=" FAAS"> FAAS</a> </p> <a href="https://publications.waset.org/abstracts/5148/extraction-of-polystyrene-from-styrofoam-waste-synthesis-of-novel-chelating-resin-for-the-enrichment-and-speciation-of-criiicrvi-ions-in-industrial-effluents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5148.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">294</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">72</span> Prevelance of Green Peach Aphid (Myzus persicae) in District Jacobabad, Sindh, Pakistran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Khan%20Abro">Kamal Khan Abro</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasreen%20Memon"> Nasreen Memon</a>, <a href="https://publications.waset.org/abstracts/search?q=Attaullah%20Ansari"> Attaullah Ansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahpara%20Pirzada"> Mahpara Pirzada</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Pathan"> Saima Pathan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Jacobabad district has a hot desert climate with very hot summers and insignificant winters.

The permeable skin makes amphibians very sensitive to the physico-chemical parameters of their aquatic environment. They spawn in water bodies where quality of water can affect the growth, development, and survival of their eggs which may die even before hatching into larvae or developing into adults due to water contamination. Considering the importance of amphibians in agriculture, food web, ecosystem and pharmaceutics as well as adverse impact of environmental degradation on them, present study was proposed to comprehensively determine the status of their diversity and habitats in Sindh province of Pakistan so as to execute monitoring for their conservation in future. Physico-chemical parameters including pH, EC (electric conductivity), TDS (total dissolved solids), T-Hard (total hardness), T-Alk (total alkalinity), Cl (chloride), CO₂ (carbon dioxide), SO₄ (sulphate), PO₄ (phosphate), NO₂ (nitrite) and NO₃ (nitrate) were analyzed from amphibian habitats using instruments and methodology of analytical grade. The results of present study after being compared with scientific data provided by different researchers and EPA (environmental protection agency), it was concluded that amphibian habitats consisted of high values of analyzed parameters except pH and CO₂. Entire study area required an urgent implementation of conservation actions for saving amphibians. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amphibians" title="amphibians">amphibians</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=habitats" title=" habitats"> habitats</a>, <a href="https://publications.waset.org/abstracts/search?q=physico-chemical%20parameters" title=" physico-chemical parameters"> physico-chemical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sindh%20Province" title=" Sindh Province"> Sindh Province</a> </p> <a href="https://publications.waset.org/abstracts/81296/amphibians-and-water-quality-an-assessment-of-diversity-and-physico-chemical-parameters-of-habitats-for-amphibians-in-sindh-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81296.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">224</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">70</span> Economical Analysis of Optimum Insulation Thickness for HVAC Duct</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Kumar">D.

In this paper, the economic impact of compression of insulation is estimated. Relevant mathematical models were used to estimate the optimal thickness at the points of compression. Furthermore, the payback period is calculated for the optimal thickness at the critical parts of supply air duct (SAD) and return air duct (RAD) considering natural gas (NG) and liquefied petroleum gas (LPG) as fuels for chillier operation. The mathematical model is developed using preliminary data obtained for an HVAC system of a pharmaceutical company. The higher heat gain and cooling loss, due to compression of thermal insulation, is estimated using relevant heat transfer equations. The results reveal that maximum energy savings (ES) in SAD is 34.5 and 40%, while in RAD is 22.9% and 29% for NG and LPG, respectively. Moreover, the minimum payback period (PP) for SAD is 2 and 1.6years, while in RAD is 4.3 and 2.7years for NG and LPG, respectively. The optimum insulation thickness (OIT) corresponding to maximum ES and minimum PP is estimated to be 35 and 42mm for SAD, while 30 and 38mm for RAD in case of NG and LPG, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimum%20insulation%20thickness" title="optimum insulation thickness">optimum insulation thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20cost%20analysis" title=" life cycle cost analysis"> life cycle cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=payback%20period" title=" payback period"> payback period</a>, <a href="https://publications.waset.org/abstracts/search?q=HVAC%20system" title=" HVAC system"> HVAC system</a> </p> <a href="https://publications.waset.org/abstracts/92533/economical-analysis-of-optimum-insulation-thickness-for-hvac-duct" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92533.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">216</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">69</span> Osteometry of the Long Bones of Adult Chinkara (Gazella bennettii): A Remarkable Example of Sexual Dimorphism </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salahud%20Din">Salahud Din</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Masood"> Saima Masood</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafsa%20Zaneb"> Hafsa Zaneb</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Ashraf"> Saima Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Imad%20Khan"> Imad Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was 1) to measure osteometric parameters of the long bones of the adult Chinkara to obtain baseline data 2) to study sexual dimorphism in the adult Chinkara through osteometry and 3) to estimate body weight from the measurements of greatest length and shaft of the long bones. For this purpose, after taking body measurements of adult Chinkara after mortality, the carcass of adult Chinkara of known sex and age were buried in the locality of the Manglot Wildlife Park and Ungulate Breeding Centre, Nizampur, Pakistan; after a specific period of time, the bones were unearthed. Various osteometric parameters of the humerus, radius, metacarpus, femur, tibia and metatarsal were measured through the digital calliper. Statistically significant (P < 0.05), differences in some of the osteometrical parameters between male and female adult Chinkara were observed. Sexual dimorphism exit between the long bones of male and female adult Chinkara. In both male and female Chinkara value obtained for the estimated body weight from humeral, metacarpal and metatarsal measurements were near to the actual body weight of the adult Chinkara. In conclusion, the present study estimates preliminary data on long bones osteometrics and suggests that the morphometric details of the male and female adult Chinkara have differed morphometrically from each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20mass%20measurements" title="body mass measurements">body mass measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinkara" title=" Chinkara"> Chinkara</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20bones" title=" long bones"> long bones</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometric" title=" morphometric"> morphometric</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20dimorphism" title=" sexual dimorphism"> sexual dimorphism</a> </p> <a href="https://publications.waset.org/abstracts/111274/osteometry-of-the-long-bones-of-adult-chinkara-gazella-bennettii-a-remarkable-example-of-sexual-dimorphism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111274.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">131</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">68</span> Analyzing the Ecosystem for Women Entrepreneurs: A Case Study of Rural Areas of Jamshoro, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20M.%20Memon">Aisha M.

The nature of this study is qualitative. Data were drawn from 25 in-depth, semi-structured interviews and a focus group discussion with women entrepreneurs in rural Jamshoro, Pakistan. The findings show the lack of awareness and knowledge among women entrepreneurs about available financial resources, lack of knowledge about laws, an absence of familial and societal support for women in accessing the entrepreneurial ecosystem, the absence of business and innovation enablers in rural areas, communication gaps, and unskilled human capital. The study found that institutions like non-for-profit organizations are playing an active role in the growth of women entrepreneurs.

The objective of this study was to assess the perception of frontline healthcare workers (HCWs) regarding the psychological impact of the COVID-19 pandemic on their children. We also sought to identify the difference in the psychological impact on children of male and female healthcare workers. Methods: A survey questionnaire was developed comprising 10 questions about the perception of HCWs regarding the psychological impact of COVID-19 on their children. It was distributed both online and face-to-face among 150 healthcare professionals working in training and non-training posts in 4 public and 5 nongovernment hospitals in Pakistan. The mean and standard deviation were calculated for each survey item using Statistical Package for the Social Sciences 26.0. Results: The response rate was 71.3%, and the majority (64.2%) of the healthcare professionals were ≥30 years of age. Ninety-two HCWs (85.98%) either agreed or strongly agreed that parental separation from their kids for long hours during the pandemic had a negative psychological impact on their children. There was a significant difference in the perceived psychological impact of COVID-19 on the children of male and female HCWs, with a mean survey score of 2.29 ± 1.82 and 1.69 ± 0.79, respectively (t = 2.29, p-value = 0.024). Conclusion: Children of healthcare workers experience more stress and anxiety because of long duty hours and working in high-risk settings. Continuous psychological support and counseling services may be adopted formally to prevent unforeseen adverse events or any long-term negative impact on their physical and mental health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare%20workers" title="healthcare workers">healthcare workers</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic" title=" pandemic"> pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological" title=" psychological"> psychological</a> </p> <a href="https://publications.waset.org/abstracts/184553/perception-of-healthcare-workers-regarding-the-psychological-impact-of-covid-19-on-their-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184553.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">51</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">66</span> Assessment of Amphibian Diversity and Status of Their Habitats through Physico-Chemical Parameters in Sindh, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kalsoom%20Shaikh">Kalsoom Shaikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Sarwar%20Gachal"> Ghulam Sarwar Gachal</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Memon"> Saima Memon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our study aimed to assess diversity and habitats of amphibian fauna in Sindh province as amphibians are among most vulnerable animals and the risk of their extinction is increasing in many parts of world mainly due to habitat degradation. Present study consisted of field surveys and laboratory analytical work; field surveys were carried out to confirm amphibian diversity and collection of water samples from their habitats, whereas laboratory work was conducted for identification of species and analysis of water quality of habitats through physico-chemical parameters. For identification of amphibian species, morphology was thoroughly examined using taxonomic key, whereas water quality was assessed via physico-chemical parameters including pH, electric conductivity (EC), total dissolved solids (TDS), total hardness (T. Hard), total alkalinity (T. Alk), chloride (Cl), carbon dioxide (CO₂), sulfate (SO₄), phosphate (PO₄), nitrite (NO₂) and nitrate (NO₃) using material and methods of analytical grade. pH value was analyzed using pH meter, whereas levels of EC and TDS were recorded using conductivity meter and TDS meter, respectively. Other parameters with exception of non-metallic parameters (SO₄, PO₄, NO₂, and NO₃) were analyzed through distinct titration methods. Concentration of non-metallic parameters was evaluated using ultra-violet spectrophotometer. This study revealed existence of four amphibian species including Hoplobatrachus tigerinus, Euphlyctis cyanophlyctis, Allopa hazarensis belonging to Family Ranidae and Bufo stomaticus (Family Bufonidae) randomly distributed in district Ghotki, Jamshoro, Kashmor, Larkana, Matiari and Shikarpur in Sindh.

In order to maintain and improve the quality by reduction in defects, Statistical tools are being used by any organizations. There are many statistical tools are available to assess the quality. Keeping in view the importance of many statistical tools, traditional 7QC tools has been used in any manufacturing and automobile Industry. Therefore, the 7QC tools have been successfully applied at one of the Automobile Company Pakistan. Preliminary survey has been done for the implementation of 7QC tool in the assembly line of Automobile Industry. During preliminary survey two inspection points were decided to collect the data, which are Chassis line and trim line. The data for defects at Chassis line and trim line were collected for reduction in defects which ultimately improve productivity. Every 7QC tools has its benefits observed from the results. The flow charts developed for better understanding about inspection point for data collection. The check sheets developed for helps for defects data collection. Histogram represents the severity level of defects. Pareto charts show the cumulative effect of defects. The Cause and Effect diagrams developed for finding the root causes of each defects. Scatter diagram developed the relation of defects increasing or decreasing. The P-Control charts developed for showing out of control points beyond the limits for corrective actions. The successful implementation of 7QC tools at the inspection points at Automobile Industry concluded that the considerable amount of reduction on defects level, as in Chassis line from 132 defects to 13 defects. The total 90% defects were reduced in Chassis Line. In Trim line defects were reduced from 157 defects to 28 defects. The total 82% defects were reduced in Trim Line. As the Automobile Company exercised only few of the 7 QC tools, not fully getting the fruits by the application of 7 QC tools. Therefore, it is suggested the company may need to manage a mechanism for the application of 7 QC tools at every section. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=check%20sheet" title="check sheet">check sheet</a>, <a href="https://publications.waset.org/abstracts/search?q=cause%20and%20effect%20diagram" title=" cause and effect diagram"> cause and effect diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20chart" title=" control chart"> control chart</a>, <a href="https://publications.waset.org/abstracts/search?q=histogram" title=" histogram"> histogram</a> </p> <a href="https://publications.waset.org/abstracts/54358/reduction-of-defects-using-seven-quality-control-tools-for-productivity-improvement-at-automobile-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54358.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">326</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">64</span> Effect of Soil Corrosion in Failures of Buried Gas Pipelines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Ali">Saima Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Pathamanathan%20Rajeev"> Pathamanathan Rajeev</a>, <a href="https://publications.waset.org/abstracts/search?q=Imteaz%20A.%20Monzur"> Imteaz A.

For this purpose, after performing postmortem examination, the carcass of adult Chinkara of known sex and age was buried in the locality of the Manglot Wildlife Park and Ungulate Breeding Centre, Nizampur, Pakistan; after a specific period of time, the bones were unearthed. Gross morphological features and various osteometric parameters of the skull were studied in the University of Veterinary and Animal Sciences, Lahore, Pakistan. The shape of the Chinkara skull was elongated and had thirty-two bones. The skull was comprised of the cranial and the facial part. The facial region of the skull was formed by maxilla, incisive, palatine, vomar, pterygoid, frontal, parietal, nasal, incisive, turbinates, mandible and hyoid apparatus. The bony region of the cranium of Chinkara was comprised of occipital, ethmoid, sphenoid, interparietal, parietal, temporal, and frontal bone. The foramina identified in the facial region of the skull of Chinkara were infraorbital, supraorbital foramen, lacrimal, sphenopalatine, maxillary and caudal palatine foramina. The foramina of the cranium of the skull of the Chinkara were the internal acoustic meatus, external acoustic meatus, hypoglossal canal, transverse canal, sphenorbital fissure, carotid canal, foramen magnum, stylomastoid foramen, foramen rotundum, foramen ovale and jugular foramen, and the rostral and the caudal foramina that formed the pterygoid canal. The measured craniometric parameters did not show statistically significant differences (p > 0.05) between male and female adult Chinkara except Palatine bone, OI, DO, IOCDE, OCT, ICW, IPCW, and PCPL were significantly higher (p > 0.05) in male than female Chinkara and mean values of the mandibular parameters except b and h were significantly (p < 0.5) higher in male Chinkara than female Chinkara. Sexual dimorphism exists in some of the orbital and foramen magnum parameters, while high levels of sexual dimorphism identified in mandible. In conclusion, morphocraniometric studies of Chinkara skull made it possible to identify species-specific skull and use clinical measurements during practical application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chinkara" title="Chinkara">Chinkara</a>, <a href="https://publications.waset.org/abstracts/search?q=skull" title=" skull"> skull</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometrics" title=" morphometrics"> morphometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20dimorphism" title=" sexual dimorphism"> sexual dimorphism</a> </p> <a href="https://publications.waset.org/abstracts/109245/gross-and-clinical-anatomy-of-the-skull-of-adult-chinkara-gazella-bennettii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109245.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">284</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">60</span> Reversible and Adaptive Watermarking for MRI Medical Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisar%20Ahmed%20Memon">Nisar Ahmed Memon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new medical image watermarking scheme delivering high embedding capacity is presented in this paper.

The proposed scheme implants, recovers the hidden information and restores the input image to its pristine state at the receiving end. Magnetic Resonance Imaging (MRI) images are used for experimental purposes. The scheme first segment the MRI medical image into non-overlapping blocks and then inserts watermark into wavelet coefficients having a high frequency of each block. The scheme uses block-based watermarking adopting iterative optimization of threshold for companding in order to avoid the histogram pre and post processing.

The speaker verification framework included the MFCCs features and the GMM modeling and classification method. The speaker verification experiments within homogeneous environments showed 5.1% increase of the EER within the clinically depressed environment when compared to the non-depressed environment. It indicated that the clinical depression increases the intra-speaker variability and makes the speaker verification task more challenging. Experiments with mixed environments indicated that the increase of the percentage of the depressed individuals within a mixed environment increases the speaker verification equal error rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speaker%20verification" title="speaker verification">speaker verification</a>, <a href="https://publications.waset.org/abstracts/search?q=GMM" title=" GMM"> GMM</a>, <a href="https://publications.waset.org/abstracts/search?q=EM" title=" EM"> EM</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20environment" title=" clinical environment"> clinical environment</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20depression" title=" clinical depression"> clinical depression</a> </p> <a href="https://publications.waset.org/abstracts/39436/effect-of-clinical-depression-on-automatic-speaker-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39436.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">375</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">58</span> Banks' Financial Performance in Pakistan from 2012-2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Akbar">Saima Akbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global financial crisis severely and adversely impacted the Pakistanis’ financial setups with far-reaching consequences for its victims.

Theorizing and practicing Islamic finance therefore under the dominant influence of modern strategy discourse and modern knowledge of finance has significant implications for developing an ethical and spiritual orientation of Islamic banks.

It includes working on the demands of different stakeholders within the projects. However, the reality of construction projects is slightly different when it comes to practice. The UK construction projects have a history of failing to complete projects on time and within the budget. The purpose of this qualitative study is to enhance knowledge of stakeholder engagement. Semi-structured interviews will be carried out using a purposive sampling technique. It includes interviewing and getting knowledge from industry practitioners from top UK construction firms on how to manage stakeholders effectively. The findings from this study will help in understanding stakeholders' impact and how the engagement of stakeholders can affect construction projects. The conclusions of this study add value to the existing body of knowledge on stakeholder management, especially in the UK, where academic studies on construction projects are few. As a contribution, this study will provide a practical guide for the practitioners to engage stakeholders within the scope of the project. In addition, this study is limited to UK construction projects. Therefore, the outcome may not be generalised to other developing and underdeveloped countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title="stakeholders">stakeholders</a>, <a href="https://publications.waset.org/abstracts/search?q=UK%20construction" title=" UK construction"> UK construction</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20management" title=" project management"> project management</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20and%20time" title=" cost and time"> cost and time</a> </p> <a href="https://publications.waset.org/abstracts/162651/managing-projects-in-practice-a-perspective-of-stakeholder-management-in-managing-stakeholders-within-the-uk-construction-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162651.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">105</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">54</span> Correlation to Predict the Effect of Particle Type on Axial Voidage Profile in Circulating Fluidized Beds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Khurram">M.

The axial voidage profile showed a typical trend along the riser: a dense bed at the lower part followed by a transition in the splash zone and a lean phase in the freeboard. Bed expansion and dense bed voidage increased with an increase of gas velocity as usual. From experimental results, a generalized model relationship based on inverse fluidization number for dense bed voidage from bubbling to fast fluidization regimes was presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20voidage" title="axial voidage">axial voidage</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20fluidized%20bed" title=" circulating fluidized bed"> circulating fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=splash%20zone" title=" splash zone"> splash zone</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20bed" title=" static bed"> static bed</a> </p> <a href="https://publications.waset.org/abstracts/55004/correlation-to-predict-the-effect-of-particle-type-on-axial-voidage-profile-in-circulating-fluidized-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55004.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">285</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">53</span> Molecular Basis for Amyloid Inhibition by L-Dopa: Implication towards Systemic Amyloidosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20H.%20Khan">Rizwan H.

Therapeutic compounds which can diminish or disaggregate such toxic oligomers and fibrillar species have been examined and more are on its way. In the present study, we had reported an extensive biophysical, microscopic and computational study, revealing that L-3, 4-dihydroxyphenylalanine (L-Dopa) possess undeniable potency to inhibit heat induced human lysozyme (HL) amyloid fibrillation and also retain the fibril disaggregating potential. L-Dopa interferes in the amyloid fibrillogenesis process by interacting hydrophobically and also by forming hydrogen bonds with the amino acid residues found in amyloid fibril forming prone region of HL as elucidated by molecular docking results. L-Dopa also disaggregates the mature amyloid fibrils into some unorganised species. Thus, L-Dopa and related compounds can work as a promising inhibitor for the therapeutic advancement prospective against systemic amyloidosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amyloids" title="amyloids">amyloids</a>, <a href="https://publications.waset.org/abstracts/search?q=disaggregation" title=" disaggregation"> disaggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20lysozyme" title=" human lysozyme"> human lysozyme</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/67120/molecular-basis-for-amyloid-inhibition-by-l-dopa-implication-towards-systemic-amyloidosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67120.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">327</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">52</span> Data Analysis to Uncover Terrorist Attacks Using Data Mining Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Nazir">Saima Nazir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustansar%20Ali%20Ghazanfar"> Mustansar Ali Ghazanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanay%20Muhammad%20Umar%20Saeed"> Sanay Muhammad Umar Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Awais%20Azam"> Muhammad Awais Azam</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Ali%20Alahmari"> Saad Ali Alahmari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Terrorism is an important and challenging concern. The entire world is threatened by only few sophisticated terrorist groups and especially in Gulf Region and Pakistan, it has become extremely destructive phenomena in recent years.

In this concern, many process improvement strategies are becoming popular in the way of increasing productivity and output. Lean manufacturing principles are among one of them, increasingly used for improving productivity by reducing wastages. Many success factors are involved in lean implementation. But, the role of senior management is most important in developing the lean culture in an organization. Purpose of this study is to investigate the perception of executive level management related to the successful implementation of lean practices and its comparison with the existing practices in the organization. In order to collect data, survey questionnaire comprised of eight statements rendering the critical success factors were sent to the top management of fifty (50) automotive manufacturing companies of Karachi. After analyzing their feedbacks, the trend of lean manufacturing principles and the commitment of senior management toward its implementation was identified in the manufacturing industries of Karachi, Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title="lean manufacturing">lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20improvement" title=" process improvement"> process improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=senior%20management" title=" senior management"> senior management</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a>, <a href="https://publications.waset.org/abstracts/search?q=involvement" title=" involvement"> involvement</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20reduction" title=" waste reduction"> waste reduction</a> </p> <a href="https://publications.waset.org/abstracts/88598/role-of-senior-management-in-implementing-lean-manufacturing-practices-a-study-of-manufacturing-companies-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88598.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">192</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">48</span> Being ‘Sciencey’: Scottish, South-Asian and Muslim Young People</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Salehjee">Saima Salehjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mike%20Watts"> Mike Watts</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In our school-based world, we are commonly confronted by young people for whom the study of science is an unpalatable ‘other world’: they simply do not see themselves as science (sciencey) people. To be clear, we are not interested in all young people becoming career scientists – although some small modicum of that would be quite agreeable. We are, though, keen to form or transform (trans(form)) their appreciations of science and retain open minds on matters scientific to develop the feeling of being ‘sciencey’ with or without the aspiration of becoming scientists. Our discussion in this paper draws upon research undertaken in a co-education primary- and lower-secondary school in Scotland, and our arguments chart the trans(formations) of thirty under-representative and under-researched Scottish South-Asian Muslim students (aged 11-13) over a school term. We use science identity theory as the basis for our analysis: what it means to be ‘sciencey’ and whether (or not) structural forces have impacted their decision of being ‘sciencey’. This work offers new insights into how Scottish, South-Asian, and Muslim students perceive and engage with in and out of school science and highlight some science nudges aimed to support their development of being ‘sciencey’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=science%20identity" title="science identity">science identity</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20nudges" title=" science nudges"> science nudges</a>, <a href="https://publications.waset.org/abstracts/search?q=transformative%20moments" title=" transformative moments"> transformative moments</a>, <a href="https://publications.waset.org/abstracts/search?q=south-Asian" title=" south-Asian"> south-Asian</a>, <a href="https://publications.waset.org/abstracts/search?q=Muslim" title=" Muslim"> Muslim</a>, <a href="https://publications.waset.org/abstracts/search?q=scottish" title=" scottish"> scottish</a>, <a href="https://publications.waset.org/abstracts/search?q=sciencey" title=" sciencey"> sciencey</a> </p> <a href="https://publications.waset.org/abstracts/147434/being-sciencey-scottish-south-asian-and-muslim-young-people" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147434.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">47</span> An Improved Modular Multilevel Converter Voltage Balancing Approach for Grid Connected PV System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safia%20Bashir">Safia Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulfiqar%20Memon"> Zulfiqar Memon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decade, renewable energy sources in particular solar photovoltaic (PV) has gained increased attention. Therefore, various PV converters topologies have emerged. Among this topology, the modular multilevel converter (MMC) is considered as one of the most promising topologies for the grid-connected PV system due to its modularity and transformerless features. When it comes to the safe operation of MMC, the balancing of the Submodules Voltages (SMs) plays a critical role. This paper proposes a balancing approach based on space vector PWM (SVPWM). Unlike the existing techniques, this method generates the switching vectors for the MMC by using only one SVPWM for the upper arm. The lower arm switching vectors are obtained by finding the complement of the upper arm switching vectors. The use of one SVPWM not only simplifies the calculation but also helped in reducing the circulating current in the MMC. The proposed method is varied through simulation using Matlab/Simulink and compared with other available modulation methods. The results validate the ability of the suggested method in balancing the SMs capacitors voltages and reducing the circulating current which will help in reducing the power loss of the PV system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitor%20voltage%20balancing" title="capacitor voltage balancing">capacitor voltage balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=circulating%20current" title=" circulating current"> circulating current</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20multilevel%20converter" title=" modular multilevel converter"> modular multilevel converter</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20system" title=" PV system "> PV system </a> </p> <a href="https://publications.waset.org/abstracts/89168/an-improved-modular-multilevel-converter-voltage-balancing-approach-for-grid-connected-pv-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89168.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">158</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">46</span> Synthesis, Molecular-Docking, and Biological Evaluation of Thiazolopyrimidine Carboxylates as Potential Antidiabetic and Antibacterial Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iram%20Batool">Iram Batool</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamer%20Saeed"> Aamer Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Irfan%20Zia%20Qureshi"> Irfan Zia Qureshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayesha%20Razzaq"> Ayesha Razzaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Kalsoom"> Saima Kalsoom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heterocyclic compounds analogues and their derivatives have attracted strong interest in medicinal chemistry due to their biological and pharmacological properties. A series of new thiazolopyrimidine carboxylates were conveniently synthesized by one-pot three-component reaction of ethyl acetoacetate, 2-aminothiazole and benzaldehyde substituted with electron-donating and electron-withdrawing groups in order to find some more potent antidiabetic and antibacterial drugs. The structures of synthesized compounds were characterized by elemental analysis, IR, 1H NMR, 13C NMR spectroscopy. An in vitro antidiabetic effect was evaluated in adult male BALB/c mice and antibacterial activities were tested against Micrococcus luteus, Salmonella typhimurium, Bacillus subtilis, Bordetella bronchiseptica and Escherichia coli. Some of the tested compounds proved to possess good to excellent activities more than the reference drugs. An in silico molecular docking was also performed on synthesized compounds. The current study is expected to provide useful insights into the design of antidiabetic and antibacterial drugs and understanding the mechanism by which such drugs interact with RNA and diabetes target and exert their biochemical action. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antidiabetic" title="antidiabetic">antidiabetic</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=MOE%20docking" title=" MOE docking"> MOE docking</a>, <a href="https://publications.waset.org/abstracts/search?q=thiazolopyrimidine" title=" thiazolopyrimidine"> thiazolopyrimidine</a> </p> <a href="https://publications.waset.org/abstracts/24188/synthesis-molecular-docking-and-biological-evaluation-of-thiazolopyrimidine-carboxylates-as-potential-antidiabetic-and-antibacterial-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24188.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">457</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">45</span> Optimization of SWL Algorithms Using Alternative Adder Module in FPGA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tayab%20D.%20Memon">Tayab D.

Results shows that SBTFF dominates upon multi-bit filter overall. In this paper, an optimized adder module for ternary quantized sigma-delta modulated signal is presented. The adder is simulated using ModelSim for functional verification the area-performance of the proposed adder were obtained through synthesis in Xilinx and compared to conventional adder trees. The synthesis results show that the proposed adder tree achieves higher clock rates and lower chip area at higher inputs to the adder block; whereas conventional adder tree achieves better performance and lower chip area at lower number of inputs to the same adder block. These results enhance the usefulness of existing short word length DSP algorithms for fast and efficient mobile communication. <p class="card-text"><strong>Keywords:</strong> <a
