Sequence data was generated from 17 species representing 09 out of 14 genera of Solanaceae from Pakistan. Cladogram was constructed using maximum parsimony method and results indicate that Solanaceae is mainly divided into two subfamilies; Solanoideae and Cestroideae. Four major clades within Solanoideae represent tribes; Physaleae, Capsiceae, Datureae and Solaneae are supported by high bootstrap value and the relationships among them are not corroborating with the previous studies. The findings established that subfamily Cestroideae comprised of three genera; Cestrum, Lycium, and Nicotiana with high bootstrap support. Position of Nicotiana inferred with atpB-rbcL sequence is congruent with traditional classification, which placed the taxa in Cestroideae. In the current study Lycium unexpectedly nested with Nicotiana with 100% bootstrap support and identified as a member of tribe Nicotianeae. Expanded sampling of other genera from Pakistan could be valuable towards improving our understanding of intrafamilial relationships within Solanaceae. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=systematics" title="systematics">systematics</a>, <a href="https://publications.waset.org/abstracts/search?q=solanaceae" title=" solanaceae"> solanaceae</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetics" title=" phylogenetics"> phylogenetics</a>, <a href="https://publications.waset.org/abstracts/search?q=intergenic%20spacer" title=" intergenic spacer"> intergenic spacer</a>, <a href="https://publications.waset.org/abstracts/search?q=tribes" title=" tribes"> tribes</a> </p> <a href="https://publications.waset.org/abstracts/1732/subfamilial-relationships-within-solanaceae-as-inferred-from-atpb-rbcl-intergenic-spacer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1732.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">468</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">171</span> Digital Encoder Based Power Frequency Deviation Measurement </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Javed%20Arif">Syed Javed Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ayyub%20Khan"> Mohd Ayyub Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleem%20Anwar%20Khan"> Saleem Anwar Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a simple method is presented for measurement of power frequency deviations. A phase locked loop (PLL) is used to multiply the signal under test by a factor of 100. The number of pulses in this pulse train signal is counted over a stable known period, using decade driving assemblies (DDAs) and flip-flops. These signals are combined using logic gates and then passed through decade counters to give a unique combination of pulses or levels, which are further encoded. These pulses are equally suitable for both control applications and display units. The experimental circuit developed gives a resolution of 1 Hz within the measurement period of 20 ms. The proposed circuit is also simulated in Verilog Hardware Description Language (VHDL) and implemented using Field Programing Gate Arrays (FPGAs). A Mixed signal Oscilloscope (MSO) is used to observe the results of FPGA implementation. These results are compared with the results of the proposed circuit of discrete components. The proposed system is useful for frequency deviation measurement and control in power systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20measurement" title="frequency measurement">frequency measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20control" title=" digital control"> digital control</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20locked%20loop" title=" phase locked loop"> phase locked loop</a>, <a href="https://publications.waset.org/abstracts/search?q=encoder" title=" encoder"> encoder</a>, <a href="https://publications.waset.org/abstracts/search?q=Verilog%20HDL" title=" Verilog HDL"> Verilog HDL</a> </p> <a href="https://publications.waset.org/abstracts/92304/digital-encoder-based-power-frequency-deviation-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92304.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">178</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">170</span> A GIS Based Approach in District Peshawar, Pakistan for Groundwater Vulnerability Assessment Using DRASTIC Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Adnan">Syed Adnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Javed%20Iqbal"> Javed Iqbal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In urban and rural areas groundwater is the most economic natural source of drinking. Groundwater resources of Pakistan are degraded due to high population growth and increased industrial development. A study was conducted in district Peshawar to assess groundwater vulnerable zones using GIS based DRASTIC model. Six input parameters (groundwater depth, groundwater recharge, aquifer material, soil type, slope and hydraulic conductivity) were used in the DRASTIC model to generate the groundwater vulnerable zones. Each parameter was divided into different ranges or media types and a subjective rating from 1-10 was assigned to each factor where 1 represented very low impact on pollution potential and 10 represented very high impact. Weight multiplier from 1-5 was used to balance and enhance the importance of each factor. The DRASTIC model scores obtained varied from 47 to 147. Using quantile classification scheme these values were reclassified into three zones i.e. low, moderate and high vulnerable zones. The areas of these zones were calculated. The final result indicated that about 400 km2, 506 km2, and 375 km2 were classified as low, moderate, and high vulnerable areas, respectively. It is recommended that the most vulnerable zones should be treated on first priority to facilitate the inhabitants for drinking purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DRASTIC%20model" title="DRASTIC model">DRASTIC model</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20vulnerability" title=" groundwater vulnerability"> groundwater vulnerability</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS%20in%20groundwater" title=" GIS in groundwater"> GIS in groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=drinking%20sources" title=" drinking sources "> drinking sources </a> </p> <a href="https://publications.waset.org/abstracts/13875/a-gis-based-approach-in-district-peshawar-pakistan-for-groundwater-vulnerability-assessment-using-drastic-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13875.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">451</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">169</span> Dietary Exposure of Heavy Metals through Cereals Commonly Consumed by Dhaka City Residents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Md.%20Bayejid%20Hosen">A.

Dietary exposure to heavy metals has been associated with toxic and adverse health effects. The main threats to human health from heavy metals are associated with exposure to Pb, Cd and Hg. The aim of this study was to monitor the presence of heavy metals in cereals collected from different wholesale markets of Dhaka City. One hundred and sixty cereal samples were collected and analyzed for determination of heavy metals. Heavy metals were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). A total of six heavy metals– lead, chromium, cadmium, mercury, arsenic and antimony were estimated. The average concentrations of heavy metals in cereals fall within the safe limit established by regulatory organizations except for Pb (152.4 μg/100g) and Hg (15.13 μg/100g) which exceeded the safe limits. BARI gom-26 was the highest source of Pb (304.1 μg/100g) whereas Haski-29 rice variety contained the highest amount of Hg (60.85 μg/100g). Though all the cereal varieties contained approximately same amount of Cr the naizer sail varieties contained huge amount of Cr (171.8 μg/100g). Among all the cereal samples miniket rice varieties contained the least amount of heavy metals. The concentration of Cr (63.24 μg/100g), Cd (5.54 μg/100g) and As (3.26 μg/100g) in all cereals were below the safe limits. The daily intake of heavy metals was determined using the total weight of cereals consumed each day multiplied by the concentrations of heavy metals in cereals. The daily intake was compared with provisional maximum tolerable daily intake set by different regulatory organizations. The daily intake of Cd (23.0 μg), Hg (63.0 μg) and as (13.6 μg) through cereals were below the risk level except for Pb (634.0 μg) and Cr (263.1 μg). As the main meal of average Bangladeshi people is boiled rice served with some sorts of vegetables, our findings indicate that the residents of Dhaka City are at risk from Pb and Cr contamination. Potential health risks from exposure to heavy metals in self-planted cereals need more attention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contamination" title="contamination">contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20exposure" title=" dietary exposure"> dietary exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20health" title=" human health"> human health</a>, <a href="https://publications.waset.org/abstracts/search?q=ICP-MS" title=" ICP-MS"> ICP-MS</a> </p> <a href="https://publications.waset.org/abstracts/28231/dietary-exposure-of-heavy-metals-through-cereals-commonly-consumed-by-dhaka-city-residents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28231.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">450</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">168</span> A 3kW Grid Connected Residential Energy Storage System with PV and Li-Ion Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moiz%20Masood%20Syed">Moiz Masood Syed</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Jun%20Hong"> Seong-Jun Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Geun-Hie%20Rim"> Geun-Hie Rim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Ae%20Cho"> Kyung-Ae Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Suk%20Kim"> Hyoung-Suk Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the near future, energy storage will play a vital role to enhance the present changing technology. Energy storage with power generation becomes necessary when renewable energy sources are connected to the grid which consequently adjoins to the total energy in the system since utilities require more power when peak demand occurs. This paper describes the operational function of a 3 kW grid-connected residential Energy Storage System (ESS) which is connected with Photovoltaic (PV) at its input side. The system can perform bidirectional functions of charging from the grid and discharging to the grid when power demand becomes high and low respectively. It consists of PV module, Power Conditioning System (PCS) containing a bidirectional DC/DC Converter and bidirectional DC/AC inverter and a Lithium-ion battery pack. ESS Configuration, specifications, and control are described. The bidirectional DC/DC converter tracks the maximum power point (MPPT) and maintains the stability of PV array in case of power deficiency to fulfill the load requirements. The bidirectional DC/AC inverter has good voltage regulation properties like low total harmonic distortion (THD), low electromagnetic interference (EMI), faster response and anti-islanding characteristics. Experimental results satisfy the effectiveness of the proposed system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20system" title="energy storage system">energy storage system</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%2FDC%20converter" title=" DC/DC converter"> DC/DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%2FAC%20inverter" title=" DC/AC inverter"> DC/AC inverter</a> </p> <a href="https://publications.waset.org/abstracts/20075/a-3kw-grid-connected-residential-energy-storage-system-with-pv-and-li-ion-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20075.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">641</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">167</span> SPR Immunosensor for the Detection of Staphylococcus aureus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali%20Syed">Muhammad Ali Syed</a>, <a href="https://publications.waset.org/abstracts/search?q=Arshad%20Saleem%20Bhatti"> Arshad Saleem Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen-zhong%20Li"> Chen-zhong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Ali%20Bokhari"> Habib Ali Bokhari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Surface plasmon resonance (SPR) biosensors have emerged as a promising technique for bioanalysis as well as microbial detection and identification. Real time, sensitive, cost effective, and label free detection of biomolecules from complex samples is required for early and accurate diagnosis of infectious diseases. Like many other types of optical techniques, SPR biosensors may also be successfully utilized for microbial detection for accurate, point of care, and rapid results. In the present study, we have utilized a commercially available automated SPR biosensor of BI company to study the microbial detection form water samples spiked with different concentration of Staphylococcus aureus bacterial cells. The gold thin film sensor surface was functionalized to react with proteins such as protein G, which was used for directed immobilization of monoclonal antibodies against Staphylococcus aureus. The results of our work reveal that this immunosensor can be used to detect very small number of bacterial cells with higher sensitivity and specificity. In our case 10^3 cells/ml of water have been successfully detected. Therefore, it may be concluded that this technique has a strong potential to be used in microbial detection and identification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20plasmon%20resonance%20%28SPR%29" title="surface plasmon resonance (SPR)">surface plasmon resonance (SPR)</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20aureus" title=" Staphylococcus aureus"> Staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensors" title=" biosensors"> biosensors</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20detection" title=" microbial detection "> microbial detection </a> </p> <a href="https://publications.waset.org/abstracts/12570/spr-immunosensor-for-the-detection-of-staphylococcus-aureus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12570.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">475</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">166</span> Properties of Bio-Phenol Formaldehyde Composites Filled with Empty Fruit Bunch Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharifah%20Nabihah%20Syed%20Jaafar">Sharifah Nabihah Syed Jaafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Umar%20Adli%20Amran"> Umar Adli Amran</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasidi%20Roslan"> Rasidi Roslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia%20Chin%20Hua"> Chia Chin Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarani%20Zakaria"> Sarani Zakaria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-composites derived from plant fiber and bio-derived polymer, are likely more ecofriendly and demonstrate competitive performance with petroleum based.

The matrix was synthesized from soda lignin, phenol and hydrochloric acid as a catalyst. The phenolic resin was synthesized via liquefaction and condensation to enhance the combination of phenol during the process. Later, the phenolic resin was mixed with EFB by using mechanical stirrer and was molded with hot press at 180 oC. In this research, the composites were prepared with EFB content of 5%, 10%, 15% and 20%. The samples that viewed under scanning electron microscopy (SEM) showed that the EFB filler remained embedded in the resin. From impact and hardness testing, samples 10% of EFB showed the optimum properties meanwhile sample 15% showed the optimum properties for flexural testing. Thermal stability of the composites was investigated using thermogravimetric (TGA) analysis and found that the weight loss and the activation energy (Ea) of the composites samples were decreased as the filler content increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EFB" title="EFB">EFB</a>, <a href="https://publications.waset.org/abstracts/search?q=liquefaction" title=" liquefaction"> liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=phenol%20formaldehyde" title=" phenol formaldehyde"> phenol formaldehyde</a>, <a href="https://publications.waset.org/abstracts/search?q=lignin" title=" lignin"> lignin</a> </p> <a href="https://publications.waset.org/abstracts/20809/properties-of-bio-phenol-formaldehyde-composites-filled-with-empty-fruit-bunch-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20809.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">589</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">165</span> Effect of Climate Change on Road Maintenance in Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Russedul%20Islam">Mohammed Russedul Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Shah%20M.%20Muniruzzaman"> Shah M.

According to scientists it is predicted that temperature will raise 1-3% and precipitation 20% by 2050 in Bangladesh. Increased temperature and precipitation will deteriorate pavement structure in an accelerated rate. The study has found that pavement life will reduce significantly due to rise in temperature and precipitation in in a coastal road in Bangladesh. It will cause to increase the maintenance cost of the road. The study has found that reduction in pavement life will be caused due the decrease in stiffness and strength parameters of the pavement material due to high temperature and precipitation. It has found that use of new material costlier than the existing one will be necessary to prevent the reduction of pavement life. Eventually it will increase the re-construction cost of the road. The study has used mechanistic-empirical analysis method with a software GAMES (General analysis on multi-layered elastic systems) to find out the effect of temperature and precipitation rise on the pavement life. The study will help to guide road engineers of Bangladesh to prepare in advance to fight with the climate change effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20cost" title=" maintenance cost"> maintenance cost</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanistic-empirical%20method" title=" mechanistic-empirical method"> mechanistic-empirical method</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20life" title=" pavement life"> pavement life</a> </p> <a href="https://publications.waset.org/abstracts/37676/effect-of-climate-change-on-road-maintenance-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37676.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">372</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">164</span> Design of an Instrumentation Setup and Data Acquisition System for a GAS Turbine Engine Using Suitable DAQ Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Nauman%20Bin%20Asghar%20Bukhari">Syed Nauman Bin Asghar Bukhari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohtashim%20Mansoor"> Mohtashim Mansoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Nouman"> Mohammad Nouman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Engine test-Bed system is a fundamental tool to measure dynamic parameters, economic performance, and reliability of an aircraft Engine, and its automation and accuracy directly influences the precision of acquired and analysed data. In this paper, we present the design of digital Data Acquisition (DAQ) system for a vintage aircraft engine test bed that lacks the capability of displaying all the analyzed parameters at one convenient location (one panel-one screen). Recording such measurements in the vintage test bed is not only time consuming but also prone to human errors. Digitizing such measurement system requires a Data Acquisition (DAQ) system capable of recording these parameters and displaying them on one screen-one panel monitor. The challenge in designing upgrade to the vintage systems arises with a need to build and integrate digital measurement system from scratch with a minimal budget and modifications to the existing vintage system. The proposed design not only displays all the key performance / maintenance parameters of the gas turbine engines for operator as well as quality inspector on separate screens but also records the data for further processing / archiving. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gas%20turbine%20engine" title="Gas turbine engine">Gas turbine engine</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20test%20cell" title=" engine test cell"> engine test cell</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20acquisition" title=" data acquisition"> data acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=instrumentation" title=" instrumentation"> instrumentation</a> </p> <a href="https://publications.waset.org/abstracts/148541/design-of-an-instrumentation-setup-and-data-acquisition-system-for-a-gas-turbine-engine-using-suitable-daq-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148541.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">123</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">163</span> Experimental Investigation of Nano-Enhanced-PCM-Based Heat Sinks for Passive Thermal Management of Small Satellites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Billy%20Moore">Billy Moore</a>, <a href="https://publications.waset.org/abstracts/search?q=Izaiah%20Smith"> Izaiah Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominic%20Mckinney"> Dominic Mckinney</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Cisco"> Andrew Cisco</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Kabir"> Mehdi Kabir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phase-change materials (PCMs) are considered one of the most promising substances to be engaged passively in thermal management and storage systems for spacecraft, where it is critical to diminish the overall mass of the onboard thermal storage system while minimizing temperature fluctuations upon drastic changes in the environmental temperature within the orbit stage. This makes the development of effective thermal management systems more challenging since there is no atmosphere in outer space to take advantage of natural and forced convective heat transfer. PCM can store or release a tremendous amount of thermal energy within a small volume in the form of latent heat of fusion in the phase-change processes of melting and solidification from solid to liquid or, conversely, during which temperature remains almost constant. However, the existing PCMs pose very low thermal conductivity, leading to an undesirable increase in total thermal resistance and, consequently, a slow thermal response time. This often turns into a system bottleneck from the thermal performance perspective. To address the above-mentioned drawback, the present study aims to design and develop various heat sinks featured by nano-structured graphitic foams (i.e., carbon foam), expanded graphite (EG), and open-cell copper foam (OCCF) infiltrated with a conventional paraffin wax PCM with a melting temperature of around 35 °C. This study focuses on the use of passive thermal management techniques to develop efficient heat sinks to maintain the electronics circuits’ and battery module’s temperature within the thermal safety limit for small spacecraft and satellites such as the Pumpkin and OPTIMUS battery modules designed for CubeSats with a cross-sectional area of approximately 4˝×4˝. Thermal response times for various heat sinks are assessed in a vacuum chamber to simulate space conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20sink" title="heat sink">heat sink</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20foams" title=" porous foams"> porous foams</a>, <a href="https://publications.waset.org/abstracts/search?q=phase-change%20material%20%28PCM%29" title=" phase-change material (PCM)"> phase-change material (PCM)</a>, <a href="https://publications.waset.org/abstracts/search?q=spacecraft%20thermal%20management" title=" spacecraft thermal management"> spacecraft thermal management</a> </p> <a href="https://publications.waset.org/abstracts/193580/experimental-investigation-of-nano-enhanced-pcm-based-heat-sinks-for-passive-thermal-management-of-small-satellites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193580.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">14</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">162</span> Mechanical and Tribological Properties of Al7075 Reinforced with Graphene-Beryl Hybrid Metal Matrix Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Haneef">Mohamed Haneef</a>, <a href="https://publications.waset.org/abstracts/search?q=Shanawaz%20Patil"> Shanawaz Patil</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Zameer"> Syed Zameer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Mohsin%20Ali"> Mohammed Mohsin Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The emerging technologies and trends of present generation requires downsizing the unwieldy structures to light weight structures on one hand and integration of varied properties on other hand to meet the application demands.

A stir casting process was used to fabricate with fixed volume fraction of 6wt% weight beryl and various volume fractions of 0.5wt%, 1wt%, 1.5wt% and 2wt% of graphene. The properties such as tensile strength, hardness and dry sliding wear behavior of hybrid composites were examined. The crystallite size and morphology of the graphene and beryl particles were analyzed with X-ray diffraction (XRD) and scanning electron microscopy (SEM) respectively. It was observed that ultimate tensile strength and hardness of the hybrid composite increased with increasing reinforcement volume fraction as compared to specimen without reinforcement additions.

Cross-country spillover growth Effects have been linked with openness and access to markets. In this research, we intend to see the short run and long run effects of Pak-India Bilateral Trade Openness upon economic growth in Pakistan. Trade Openness has been measured as the sum of bilateral exports and imports between the two countries. Increased emphasis on the condition and environment of financial markets is laid in light of globalization and trade liberalization. This research paper makes use of the Univariate Autoregressive Distributed Lagged Model to analyze the effects of bilateral trade variables upon the growth pattern of Pakistan in the short run and long run. Key findings of the study empirically support the notion that increased bilateral trade will be beneficial for Pakistan in the short run because of cost advantage and knowledge spillover in terms of increased technical and managerial ability from multinational firms. However, contrary to extensive literature, increased bilateral trade measures will affect Pakistan’s growth rate negatively in the long run because of the industrial size differential and increased integration of Indian economy with the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilateral%20trade%20openness" title="bilateral trade openness">bilateral trade openness</a>, <a href="https://publications.waset.org/abstracts/search?q=spillover" title=" spillover"> spillover</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20advantage" title=" comparative advantage"> comparative advantage</a>, <a href="https://publications.waset.org/abstracts/search?q=univariate" title=" univariate"> univariate</a> </p> <a href="https://publications.waset.org/abstracts/15687/modeling-spillover-effects-of-pakistan-india-bilateral-trade-upon-sustainability-of-economic-growth-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15687.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">481</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">160</span> Political Islam: From Coinage to Hot Debate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajid%20Iqbal%20Sheikh">Sajid Iqbal Sheikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From almost last 100 years 'political islam' has diversity in its usage as terminology in the speculative works of both muslim and non-muslims theorists. 'Political islam' as a term was coined consciously as equal to the 'militant islam' and “Terrorist Islam” vs “Plain Islam” and “Modern Islam” etc. Many paradigm shifts tamed the term into one of the hottest debate of the day. This research paper aims to categorize historical linkage of its coinage, development phases and present status. Based on content analysis, Narrative approach has been utilized for the sake of dexterous conclusion. The paper treasures out that Western dominance on civilizational and political spheres of the holistic world considers 'political islam' a gigantic threat and plans to resist it in theoretic and practical fields simultaneously. Despite minor strategic variances, the ideological followers of Syed Qutab, Mulana Mudoodi and Hasan Al-Bana, are struggling hard for the achievement of their ultimate goal of Political change, specifically in the Muslim World in the prior phase. The paper concludes that Resistance to Islamic resurgence and its Political goals is being observed in most of the Muslim world, especially in the Turkey, Algeria, Egypt, Tsunia and Yeman etc, which is a basic cause of contrary reaction in the Muslim World. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electoral%20process" title="electoral process">electoral process</a>, <a href="https://publications.waset.org/abstracts/search?q=islamic%20resurgence" title=" islamic resurgence"> islamic resurgence</a>, <a href="https://publications.waset.org/abstracts/search?q=islamic%20political%20theory" title=" islamic political theory"> islamic political theory</a>, <a href="https://publications.waset.org/abstracts/search?q=muslim%20response" title=" muslim response"> muslim response</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20hegemony" title=" western hegemony"> western hegemony</a> </p> <a href="https://publications.waset.org/abstracts/34532/political-islam-from-coinage-to-hot-debate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34532.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">450</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">159</span> The Reality of Teaching Arabic for Specific Purposes in Educational Institutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Anwarul%20Kabir">Mohammad Anwarul Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Fayezul%20Islam"> Fayezul Islam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Language invariably is learned / taught to be used primarily as means of communications. Teaching a language for its native audience differs from teaching it to non-native audience. Moreover, teaching a language for communication only is different from teaching it for specific purposes. Arabic language is primarily regarded as the language of the Quran and the Sunnah (Prophetic tradition). Arabic is, therefore, learnt and spread all over the globe. However, Arabic is also a cultural heritage shared by all Islamic nations which has used Arabic for a long period to record the contributions of Muslim thinkers made in the field of wide spectrum of knowledge and scholarship. That is why the phenomenon of teaching Arabic by different educational institutes became quite rife, and the idea of teaching Arabic for specific purposes is heavily discussed in the academic sphere. Although the number of learners of Arabic is increasing consistently, yet their purposes vary. These include religious purpose, international trade, diplomatic purpose, better livelihood in the Arab world extra. By virtue of this high demand for learning Arabic, numerous institutes have been established all over the world including Bangladesh. This paper aims at focusing on the current status of the language institutes which has been established for learning Arabic for specific purposes in Bangladesh including teaching methodology, curriculum, and teachers’ quality. Such curricula and using its materials resulted in a lot of problems. The least, it confused teachers and students as well. Islamic educationalists have been working hard to professionally meet the need. They are following a systematic approach of stating clear and achievable goals, building suitable content, and applying new technology to present these learning experiences and evaluate them. It also suggests a model for designing instructional systems that responds to the need of non-Arabic speaking Islamic communities and provide the knowledge needed in both linguistic and cultural aspects. It also puts forward a number of suggestions for the improvement of the teaching / learning Arabic for specific purposes in Bangladesh after a detailed investigation in the following areas: curriculum, teachers’ skills, method of teaching and assessment policy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication" title="communication">communication</a>, <a href="https://publications.waset.org/abstracts/search?q=Quran" title=" Quran"> Quran</a>, <a href="https://publications.waset.org/abstracts/search?q=sunnah" title=" sunnah"> sunnah</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20institutes" title=" educational institutes"> educational institutes</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20purposes" title=" specific purposes"> specific purposes</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum" title=" curriculum"> curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=method%20of%20teaching" title=" method of teaching"> method of teaching</a> </p> <a href="https://publications.waset.org/abstracts/47958/the-reality-of-teaching-arabic-for-specific-purposes-in-educational-institutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47958.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">282</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">158</span> Effect of Atmospheric Turbulence on Hybrid FSO/RF Link Availability under Qatar's Harsh Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Touati">Abir Touati</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Jawad%20Hussain"> Syed Jawad Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Touati"> Farid Touati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Bouallegue"> Ammar Bouallegue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although there has been a growing interest in the hybrid free-space optical link and radio frequency FSO/RF communication system, the current literature is limited to results obtained in moderate or cold environment. In this paper, using a soft switching approach, we investigate the effect of weather inhomogeneities on the strength of turbulence hence the channel refractive index under Qatar harsh environment and their influence on the hybrid FSO/RF availability. In this approach, either FSO/RF or simultaneous or none of them can be active. Based on soft switching approach and a finite state Markov Chain (FSMC) process, we model the channel fading for the two links and derive a mathematical expression for the outage probability of the hybrid system. Then, we evaluate the behavior of the hybrid FSO/RF under hazy and harsh weather. Results show that the FSO/RF soft switching renders the system outage probability less than that of each link individually. A soft switching algorithm is being implemented on FPGAs using Raptor code interfaced to the two terminals of a 1Gbps/100 Mbps FSO/RF hybrid system, the first being implemented in the region.

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.

Its physical size and performance are vital parameters; therefore enhancement of heat transfer through different techniques remained a major research area for both academia and industry. This research reports the main purpose of heat exchanger with better kit design which plays a vital role during the process of heat transfer. Plate type heat exchanger mainly requires a design in which the plates can be easily be installed and removed without having any problem with the plates. For the flow of the fluid within the heat exchanger, it requires a flow should be fully developed. As natural laws allows the driving energy of the system to flow until equilibrium is achieved. As with a plate type heat exchanger heat the heat penetrates the surface which separates the hot medium with the cold one very easily. As some of the precautions should be considered while taking the heat exchanger accountable like heat should transfer from hot medium to cold, there should always be difference in temperature present and heat loss from hot body should be equal to the heat gained by the cold body regardless of the losses present to the surroundings.

Palliative care is not a curative treatment but a comprehensive care to ensure the well-being of patients. This study was to identify the perceptions of patients and carers on healthcare needs and any factors related to the needs of palliative patients. Validated questionnaires survey of 254 patients and carers were analysed using a Statistical Package for the Social Sciences (SPSS) version 22. The findings were processed with Cronbach Alpha analysis, frequency, and descriptive to compare the important of each element in healthcare. Open-ended responses were analysed using thematic framework approach. The findings proved that all the items in healthcare needs elements were important because the frequency shown higher values, which were physical needs (5.91), mental needs (6.10), spiritual needs (6.34), emotional needs (6.05), social needs (5.88) and logistics needs (5.05). The total score of Cronbach’s alpha (α) for this study is 0.958, which is suggesting very good internal consistency reliability for the elements for healthcare needs. Professionals and healthcare providers need to ensure healthcare planning is individualised by tailoring it to the values, priorities, and ethnic/cultural/religious context of each person. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare" title="healthcare">healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=need" title=" need"> need</a>, <a href="https://publications.waset.org/abstracts/search?q=holistic" title=" holistic"> holistic</a>, <a href="https://publications.waset.org/abstracts/search?q=palliative" title=" palliative"> palliative</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20speciality" title=" multi speciality"> multi speciality</a> </p> <a href="https://publications.waset.org/abstracts/149313/perception-towards-palliative-patients-healthcare-needs-a-survey-of-patients-and-carers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149313.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">87</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">154</span> Efficient Photocatalytic Degradation of Tetracycline Hydrochloride Using Modified Carbon Nitride CCN/Bi₂WO₆ Heterojunction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Najeeb-Uz-Zaman%20Haider">Syed Najeeb-Uz-Zaman Haider</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Juan"> Yang Juan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibiotic overuse raises environmental concerns, boosting the demand for efficient removal from pharmaceutical wastewater. Photocatalysis, particularly using semiconductor photocatalysts, offers a promising solution and garners significant scientific interest. In this study, a Z-scheme 0.15BWO/CCN heterojunction was developed, analyzed, and employed for the photocatalytic degradation of tetracycline hydrochloride (TC) under visible light. The study revealed that the dosage of 0.15BWO@CCN and the presence of coexisting ions significantly influenced the degradation efficiency, achieving up to 87% within 20 minutes under optimal conditions (at pH 9-11/strongly basic conditions) while maintaining 84% efficiency under standard conditions (unaltered pH). Photoinduced electrons gathered on the conduction band of BWO while holes accumulated on the valence band of CCN, creating more favorable conditions to produce superoxide and hydroxyl radicals. Additionally, through comprehensive experimental analysis, the degradation pathway and mechanism were thoroughly explored. The superior photocatalytic performance of 0.15BWO@CCN was attributed to its Z-scheme heterojunction structure, which significantly reduced the recombination of photoinduced electrons and holes. The radicals produced were identified using ESR, and their involvement in tetracycline degradation was further analyzed through active species trapping experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CCN" title="CCN">CCN</a>, <a href="https://publications.waset.org/abstracts/search?q=Bi%E2%82%82WO%E2%82%86" title=" Bi₂WO₆"> Bi₂WO₆</a>, <a href="https://publications.waset.org/abstracts/search?q=TC" title=" TC"> TC</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalytic%20degradation" title=" photocatalytic degradation"> photocatalytic degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=heterojunction" title=" heterojunction"> heterojunction</a> </p> <a href="https://publications.waset.org/abstracts/186128/efficient-photocatalytic-degradation-of-tetracycline-hydrochloride-using-modified-carbon-nitride-ccnbi2wo6-heterojunction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186128.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">44</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">153</span> Synthesis, Characterization and Applications of Some Selected Dye-Functionalized P and N-Type Nanoparticles in Dye Sensitized Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arifa%20Batool">Arifa Batool</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Hussain%20Bhatti"> Ghulam Hussain Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Mujtaba%20Shah"> Syed Mujtaba Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inorganic n-type (TiO2, CdO) and p-type (NiO, CuO) metal oxide nanoparticles were synthesized by a facile wet chemical method at room temperature.

The work aim is to examine the potential of using kenaf fibres to improve the strength and ductility of the OPSRC beams and also observe its potential in serving as part of shear reinforcement in the beams. Two different arrangements of the shear links in OPSRC beams with a selection of kenaf fibres (amount of [10kg/m] ^3 and [20kg/m] ^3) content are tested under monotonic loading. In the first arrangement, the kenaf fibres are added to the beam which has full shear reinforcement to study the structural behavior of OPSRC beams with fibres. In the second arrangement, the spacing between the shear links in the OPSRC beams are increased by 50% and experimental work is carried out to study the effect of kenaf fibres without compromising the beams strength and ductility. The results show that the addition of kenaf fibres enhanced the load carrying capacity, ductility and also altered the failure mode of the beams from a brittle shear mode to a flexural ductile one. Furthermore, the study depicts that kenaf fibres are compatible with OPSRC and suggest prospective results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20shell%20reinforced%20concrete" title="oil palm shell reinforced concrete">oil palm shell reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=kenaf%20fibres" title=" kenaf fibres"> kenaf fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20strength" title=" peak strength"> peak strength</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a> </p> <a href="https://publications.waset.org/abstracts/5706/behavior-of-oil-palm-shell-reinforced-concrete-beams-added-with-kenaf-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5706.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">431</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">151</span> BIM Data and Digital Twin Framework: Preserving the Past and Predicting the Future</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mazharuddin%20Syed%20Ahmed">Mazharuddin Syed Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research presents a framework used to develop The Ara Polytechnic College of Architecture Studies building “Kahukura” which is Green Building certified.

Traditional bacterial inactivation methods (e.g., ultraviolet radiation and chlorination) have several limitations such as longer treatment time, formation of toxic byproducts, bacterial regrowth, etc. Recently, an electroporation-based inactivation method was introduced as a substitute. Here, an electroporation-based continuous flow microfluidic device equipped with an array of micropillars is developed, and the device achieved high bacterial inactivation performance ( > 99.9%) within a short exposure time ( < 1 s). More than 99.9% reduction of Escherichia coli bacteria was obtained for the flow rate of 1 mL/hr, and no regrowth of bacteria was observed. Images from scanning electron microscope confirmed the formation of electroporation-induced nano-pore within the cell membrane. Through numerical simulation, it has been shown that sufficiently large electric field strength (3 kV/cm), required for bacterial electroporation, were generated using PDMS micropillars for an applied voltage of 300 V. Further, in this method of inactivation, there is no involvement of chemicals and the formation of harmful by-products is also minimum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroporation" title="electroporation">electroporation</a>, <a href="https://publications.waset.org/abstracts/search?q=high-efficiency" title=" high-efficiency"> high-efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=inactivation" title=" inactivation"> inactivation</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=micropillar" title=" micropillar"> micropillar</a> </p> <a href="https://publications.waset.org/abstracts/104675/micropillar-assisted-electric-field-enhancement-for-high-efficiency-inactivation-of-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104675.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">180</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">149</span> Government (Big) Data Ecosystem: Definition, Classification of Actors, and Their Roles </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Iftikhar%20Hussain%20Shah">Syed Iftikhar Hussain Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilis%20Peristeras"> Vasilis Peristeras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Magnisalis"> Ioannis Magnisalis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organizations, including governments, generate (big) data that are high in volume, velocity, veracity, and come from a variety of sources.

In this paper, we present a method for calculation of optimal weight vectors for smart antenna array, to achieve a directive pattern during transmission and selective reception in interference prone environment. In proposed scheme, Mutual Information (MI) extrema are evaluated through an energy constrained objective function, which is based on a-priori information of interference source and desired array factor. Signal to Interference plus Noise Ratio (SINR) performance is evaluated for both transmission and reception. In our scheme, MI is presented as an index to identify trade-off between information gain, SINR, illumination time and spatial selectivity in an energy constrained optimization problem. The employed method yields lesser computational complexity, which is presented through comparative analysis with conventional methods in vogue.

This study was aimed to evaluate the prevalence of polypharmacy in elderly Saudi cardiac patient. A retrospective observational study was carried out at the department of CCU and cardiology unit of the King Fahad cardiac centre (KFCC) in King Khalid university hospital from May 2012 to October 2012. All Parameters was analyzed by using Statistical Packages for Social Science (SPSS) to conclude the result; tests of association were performed using the chi-square statistic. The mean age of patients was 70.1 ± 7.75 years, more than half 83 (51.6%) were males. The highest frequency of chronic diseases found were hypertension (91.0%) followed by, dyslipidemia (74.9%), and diabetes mellitus. Results showed that 82% had polypharmacy (>4 drugs) during the study period, and 47.9% had major polypharmacy. The incidence of inappropriate drug use was found to be higher with men than female (p = 0.984). In conclusion, this study revealed that high prevalence of polypharmacy and potentially inappropriate medications in elderly Saudi cardiac inpatients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20inpatients" title="cardiac inpatients">cardiac inpatients</a>, <a href="https://publications.waset.org/abstracts/search?q=medications" title=" medications"> medications</a>, <a href="https://publications.waset.org/abstracts/search?q=polypharmacy" title=" polypharmacy"> polypharmacy</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a> </p> <a href="https://publications.waset.org/abstracts/14611/prevalence-of-polypharmacy-in-elderly-cardiac-patients-at-king-fahad-cardiac-center-kfcc-in-king-khalid-university-hospital-kkuh-riyadh-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14611.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">734</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">146</span> Biosynthesis of Selenium Oxide Nanoparticles by Streptomyces bikiniensis and Its Cytotoxicity as Antitumor Agents against Hepatocellular and Breast Cells Carcinoma </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maged%20Syed%20Ahamd">Maged Syed Ahamd</a>, <a href="https://publications.waset.org/abstracts/search?q=Manal%20Mohamed%20Yasser"> Manal Mohamed Yasser</a>, <a href="https://publications.waset.org/abstracts/search?q=Essam%20Sholkamy"> Essam Sholkamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we reported that selenium (Se) nanoparticles were firstly biosynthesized with a simple and eco-friendly biological method. Their shape, size, FTIR (Fourier Transform Infrared spectroscopy), UV–vis spectra, TEM (Transmission Electron Microscopy) images and EDS (Energy Dispersive Spectroscopy) pattern have been analyzed. TEM analyses of the samples obtained at different stages indicated that the formation of these Se nanostructures was governed by an incubation time (12- 24- 48 hours). The Se nanoparticles were initially generated and then would transform into crystal seeds for the subsequent growth of nanowires; however obtaining stable Se nanowire with a diameter of about 15-100 nm. EDS shows that Se nanoparticles are entirely pure. The IR spectra showed the peaks at 550 cm-1, 1635 cm-1, 1994 cm-1 and 3430 cm-1 correspond to the presence of Se-O bending and stretching vibrations. The concentrations of Se-NPs (0, 1, 2, 5 µg/ml) did not give significantly effect on both two cell lines while the highest concentrations (10- 100 µg/ml gave significantly effects on them. The lethal dose (ID50%) of Se-NPs on Hep2 G and MCF-7 cells was obtained at 75.96 and 61.86 µg/ml, respectively. Results showed that Se nanoparticles as anticancer agent against MCF-7 cells were more effective than Hep2 G cells. Our results suggest that Se-NPs may be a candidate for further evaluation as a chemotherapeutic agent for breast and liver cancers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=selenium%20nanoparticle" title="selenium nanoparticle">selenium nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=Streptomyces%20bikiniensis" title=" Streptomyces bikiniensis"> Streptomyces bikiniensis</a>, <a href="https://publications.waset.org/abstracts/search?q=nanowires" title=" nanowires"> nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=chemotherapeutic%20agent" title=" chemotherapeutic agent"> chemotherapeutic agent</a> </p> <a href="https://publications.waset.org/abstracts/20175/biosynthesis-of-selenium-oxide-nanoparticles-by-streptomyces-bikiniensis-and-its-cytotoxicity-as-antitumor-agents-against-hepatocellular-and-breast-cells-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20175.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">445</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">145</span> An Improved Data Aided Channel Estimation Technique Using Genetic Algorithm for Massive Multi-Input Multiple-Output</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kislu%20Noman">M.

To cope with such crowdy and messy situation, massive MIMO is designed to work with hundreds of low costs serving antennas at a time as well as improve the spectral efficiency at the same time. TDD has been used for gaining beamforming which is a major part of massive MIMO, to gain its best improvement to transmit and receive pilot sequences. All the benefits are only possible if the channel state information or channel estimation is gained properly. The common methods to estimate channel matrix used so far is LS, MMSE and a linear version of MMSE also proposed in many research works. We have optimized these methods using genetic algorithm to minimize the mean squared error and finding the best channel matrix from existing algorithms with less computational complexity. Our simulation result has shown that the use of GA worked beautifully on existing algorithms in a Rayleigh slow fading channel and existence of Additive White Gaussian Noise. We found that the GA optimized LS is better than existing algorithms as GA provides optimal result in some few iterations in terms of MSE with respect to SNR and computational complexity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=channel%20estimation" title="channel estimation">channel estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=LMMSE" title=" LMMSE"> LMMSE</a>, <a href="https://publications.waset.org/abstracts/search?q=LS" title=" LS"> LS</a>, <a href="https://publications.waset.org/abstracts/search?q=MIMO" title=" MIMO"> MIMO</a>, <a href="https://publications.waset.org/abstracts/search?q=MMSE" title=" MMSE"> MMSE</a> </p> <a href="https://publications.waset.org/abstracts/103496/an-improved-data-aided-channel-estimation-technique-using-genetic-algorithm-for-massive-multi-input-multiple-output" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103496.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">191</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">144</span> Government Big Data Ecosystem: A Systematic Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Iftikhar%20Hussain%20Shah">Syed Iftikhar Hussain Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilis%20Peristeras"> Vasilis Peristeras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Magnisalis"> Ioannis Magnisalis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data that is high in volume, velocity, veracity and comes from a variety of sources is usually generated in all sectors including the government sector. Globally public administrations are pursuing (big) data as new technology and trying to adopt a data-centric architecture for hosting and sharing data. Properly executed, big data and data analytics in the government (big) data ecosystem can be led to data-driven government and have a direct impact on the way policymakers work and citizens interact with governments. In this research paper, we conduct a systematic literature review. The main aims of this paper are to highlight essential aspects of the government (big) data ecosystem and to explore the most critical socio-technical factors that contribute to the successful implementation of government (big) data ecosystem. The essential aspects of government (big) data ecosystem include definition, data types, data lifecycle models, and actors and their roles. We also discuss the potential impact of (big) data in public administration and gaps in the government data ecosystems literature. As this is a new topic, we did not find specific articles on government (big) data ecosystem and therefore focused our research on various relevant areas like humanitarian data, open government data, scientific research data, industry data, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=applications%20of%20big%20data" title="applications of big data">applications of big data</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data%20types.%20big%20data%20ecosystem" title=" big data types. big data ecosystem"> big data types. big data ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20success%20factors" title=" critical success factors"> critical success factors</a>, <a href="https://publications.waset.org/abstracts/search?q=data-driven%20government" title=" data-driven government"> data-driven government</a>, <a href="https://publications.waset.org/abstracts/search?q=egovernment" title=" egovernment"> egovernment</a>, <a href="https://publications.waset.org/abstracts/search?q=gaps%20in%20data%20ecosystems" title=" gaps in data ecosystems"> gaps in data ecosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20%28big%29%20data" title=" government (big) data"> government (big) data</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20administration" title=" public administration"> public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review"> systematic review</a> </p> <a href="https://publications.waset.org/abstracts/116280/government-big-data-ecosystem-a-systematic-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116280.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">229</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">143</span> Challenges and Opportunities for Implementing Integrated Project Delivery Method in Public Sector Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Ahmed">Ahsan Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Lu"> Ming Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Zaidi"> Syed Zaidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Khan"> Farhan Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Integrated Project Delivery (IPD) method has been proposed as the solution to tackle complexity and fragmentation in the real world while addressing the construction industry’s growing needs for productivity and sustainability. Although the private sector has taken the initiative in implementing IPD and taken advantage of new technology such as building information modeling (BIM) in delivering projects, IPD remains less known and rarely used in public sector construction. The focus of this paper is set on the use of IPD in projects in public sector, which is potentially complemented by the use of analytical functionalities for workface planning and construction oriented design enabled by recent research advances in BIM. Experiences and lessons learned from implementing IPD in the private sector and in BIM-based construction automation research would play a vital role in reducing barriers and eliminating issues in connection with project delivery in the public sector. The paper elaborates issues challenges, contractual relationships and the interactions throughout the planning, design and construction phases in the context of implementing IPD on construction projects in the public sector. A slab construction case is used as a ‘sandbox’ model to elaborate (1) the ideal way of communication, integration, and collaboration among all the parties involved in project delivery in planning and (2) the execution of projects by using IDP principles and optimization, simulation analyses. <p class="card-text"><strong>Keywords:</strong> <a
