placed in their axilla for a period of 6-10 days. We evaluated the post-op course of patients who underwent breast conservation surgery (BCS) along with ALND. Methods: A prospective cohort study was conducted at Shaukat Khanam Memorial Cancer Hospital from April 2017 to August 2017 including all lymph node positive breast cancer patients undergoing BCS with ALND. Patients were divided into two groups. Group A had no axillary drain while in Group B a drain was placed in axilla. Results: A total of 76 patients were included. 41 patients were included in group A and 35 patients in Group B. Median number of LNs dissected in group A was 17 and in group B was 15 (p value 0.443). Median operative time in group A was 84 min and in group B was 79 min (p value 0.223). Median hospital stay in both groups was 1 day (p value 0.78). At 2 weeks all patients in group A developed seroma as compared to none in group B (p value < 0.001). 3 of these patients in group A required aspiration of seroma due to pressure effects. Rest were managed conservatively. At 6 weeks only 50% patients had a seroma radiologically in Group A as compared to 33% in group B (p value 0.023). No intervention was required in any patients at week 6. QOL at 2 weeks was much better in Group A (7/41 patients had unsatisfactory response) as compared to group B (10/31 had unsatisfactory response). Results were statistically significant (p value 0.045). However, there wasn’t much difference in QOL at 6 weeks. Only 1 patient in group A had an unsatisfactory response. Average pain score at 2 weeks was similar in both groups (4.2 v/s 4.1 p value 0.73). Infection was seen in 1 patient in each group at 2 weeks (p value 0.668) and in only 1 patient in group A at 6 weeks (p value 0.067). Conclusion: We conclude from our study that there isn’t much difference in drain and no drain group in terms of wound infection and pain scores. No drain group is however associated with a better QOL in early post-op period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axillary%20drainage" title="axillary drainage">axillary drainage</a>, <a href="https://publications.waset.org/abstracts/search?q=axillary%20lymph%20node%20dissection" title=" axillary lymph node dissection"> axillary lymph node dissection</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=no%20drain%20in%20axilla" title=" no drain in axilla"> no drain in axilla</a> </p> <a href="https://publications.waset.org/abstracts/101018/a-prospective-review-of-axillary-drainage-in-axillary-lymph-node-dissection-in-breast-conservation-cancer-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101018.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">190</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> BOX Effect Sensitivity to Fin Width in SOI-Multi-FinFETs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20N.%20Moulai%20Khatir">A.

The corner effect may also exist in the two lower corners; this effect is called the BOX effect, which can also occur in the direction X-Z. The electric field lines from the source and drain cross the bottom oxide and arrive in the silicon. This effect is also called DIVSB (Drain Induced Virtual Substrate Basing). The potential in the silicon film in particular near the drain is increased by the drain bias. It is similar to DIBL and result in a decrease of the threshold voltage. This work provides an understanding of the limitation of this effect by reducing the fin width for components with increased fin number. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SOI" title="SOI">SOI</a>, <a href="https://publications.waset.org/abstracts/search?q=finFET" title=" finFET"> finFET</a>, <a href="https://publications.waset.org/abstracts/search?q=corner%20effect" title=" corner effect"> corner effect</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-gate" title=" dual-gate"> dual-gate</a>, <a href="https://publications.waset.org/abstracts/search?q=tri-gate" title=" tri-gate"> tri-gate</a>, <a href="https://publications.waset.org/abstracts/search?q=BOX" title=" BOX"> BOX</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-finFET" title=" multi-finFET"> multi-finFET</a> </p> <a href="https://publications.waset.org/abstracts/32683/box-effect-sensitivity-to-fin-width-in-soi-multi-finfets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32683.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">496</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">142</span> Patients’ Perspective on Early Discharge with Drain in situ after Breast Cancer Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laila%20Al-Balushi">Laila Al-Balushi</a>, <a href="https://publications.waset.org/abstracts/search?q=Suad%20Al-Kharosui"> Suad Al-Kharosui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increasing number of breast cancer cases in Oman and the impact of the novel coronavirus disease 2019 (COVID-19 on bed situation in the hospital, a policy of early discharge (ED) with drain after breast cancer surgery was initiated at one of the tertiary hospitals in Oman. The uniqueness of this policy is no home visit follow-up, conducted after discharge and the main mode of communication was Instagram media. This policy then was evaluated by conducting a quasi-experimental study using a questionnaire with ten open and closed-ended questions, five questions to explore patient experience using a five-point Likert scale. A total of 41 female patients responded to the questionnaire. Almost 96% of the participants stated being well informed about drain care pre- and post-surgery at home. 9% of the participants developed early sign of infection and was managed at out-patient clinics. Participants with bilateral drains expressed more pain than those with single drain. 90% stated satisfied being discharged with breast drain whereas 10% preferred to stay in the hospital until the drains were removed. This study found that the policy of ED with a drain after BC surgery is practical and well-accepted by most patients. The role of breast nurse and presence of family and institutional support enhanced the success of the policy implementation. To optimize patient care, conducting a training program by breast nurse for nurses at local health centres about care management of patients with drain could improve care and enhance patient satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20discharge" title=" early discharge"> early discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20drain" title=" surgical drain"> surgical drain</a> </p> <a href="https://publications.waset.org/abstracts/150421/patients-perspective-on-early-discharge-with-drain-in-situ-after-breast-cancer-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150421.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">95</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">141</span> Analytical Modeling of Drain Current for DNA Biomolecule Detection in Double-Gate Tunnel Field-Effect Transistor Biosensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashwani%20Kumar">Ashwani Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract- This study presents an analytical modeling approach for analyzing the drain current behavior in Tunnel Field-Effect Transistor (TFET) biosensors used for the detection of DNA biomolecules. The proposed model focuses on elucidating the relationship between the drain current and the presence of DNA biomolecules, taking into account the impact of various device parameters and biomolecule characteristics. Through comprehensive analysis, the model offers insights into the underlying mechanisms governing the sensing performance of TFET biosensors, aiding in the optimization of device design and operation. A non-local tunneling model is incorporated with other essential models to accurately trace the simulation and modeled data. An experimental validation of the model is provided, demonstrating its efficacy in accurately predicting the drain current response to DNA biomolecule detection. The sensitivity attained from the analytical model is compared and contrasted with the ongoing research work in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosensor" title="biosensor">biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=double-gate%20TFET" title=" double-gate TFET"> double-gate TFET</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20detection" title=" DNA detection"> DNA detection</a>, <a href="https://publications.waset.org/abstracts/search?q=drain%20current%20modeling" title=" drain current modeling"> drain current modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/183041/analytical-modeling-of-drain-current-for-dna-biomolecule-detection-in-double-gate-tunnel-field-effect-transistor-biosensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183041.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">57</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">140</span> Effect of Prefabricated Vertical Drain System Properties on Embankment Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhasan%20Naeini">Seyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Namaei"> Ali Namaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the effect of prefabricated vertical drain system properties on embankment behavior by calculating the settlement, lateral displacement and induced excess pore pressure by numerical method. In order to investigate this behavior, three different prefabricated vertical drains have been simulated under an embankment. The finite element software PLAXIS has been carried out for analyzing the displacements and excess pore pressures. The results showed that the consolidation time and induced excess pore pressure are highly depended to the discharge capacity of the prefabricated vertical drain. The increase in the discharge capacity leads to decrease the consolidation process and the induced excess pore pressure. Moreover, it was seen that the vertical drains spacing does not have any significant effect on the consolidation time. However, the increase in the drains spacing would decrease the system stiffness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertical%20drain" title="vertical drain">vertical drain</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated" title=" prefabricated"> prefabricated</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidation" title=" consolidation"> consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=embankment" title=" embankment"> embankment</a> </p> <a href="https://publications.waset.org/abstracts/109050/effect-of-prefabricated-vertical-drain-system-properties-on-embankment-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109050.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Suppressing Ambipolar Conduction Using Dual Material Gate in Tunnel-FETs Having Heavily Doped Drain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dawit%20Burusie%20Abdi">Dawit Burusie Abdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamidala%20Jagadesh%20Kumar"> Mamidala Jagadesh Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, using 2D TCAD simulations, the application of a dual material gate (DMG) for suppressing ambipolar conduction in a tunnel field effect transistor (TFET) is demonstrated. Using the proposed DMG concept, the ambipolar conduction can be effectively suppressed even if the drain doping is as high as that of the source doping. Achieving this symmetrical doping, without the ambipolar conduction in TFETs, gives the advantage of realizing both n-type and p-type devices with the same doping sequences. Furthermore, the output characteristics of the DMG TFET exhibit a good saturation when compared to that of the gate-drain underlap approach. This improved behavior of the DMG TFET makes it a good candidate for inverter based logic circuits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20material%20gate" title="dual material gate">dual material gate</a>, <a href="https://publications.waset.org/abstracts/search?q=suppressing%20ambipolar%20current" title=" suppressing ambipolar current"> suppressing ambipolar current</a>, <a href="https://publications.waset.org/abstracts/search?q=symmetrically%20doped%20TFET" title=" symmetrically doped TFET"> symmetrically doped TFET</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel%20FETs" title=" tunnel FETs"> tunnel FETs</a>, <a href="https://publications.waset.org/abstracts/search?q=PNPN%20TFET" title=" PNPN TFET"> PNPN TFET</a> </p> <a href="https://publications.waset.org/abstracts/42462/suppressing-ambipolar-conduction-using-dual-material-gate-in-tunnel-fets-having-heavily-doped-drain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42462.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">370</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">138</span> Comparison of 18F-FDG and 11C-Methionine PET-CT for Assessment of Response to Neoadjuvant Chemotherapy in Locally Advanced Breast Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Mahajan%20Dinesh">Sonia Mahajan Dinesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anant%20Dinesh"> Anant Dinesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhavi%20Tripathi"> Madhavi Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Kumar%20Ramteke"> Vinod Kumar Ramteke</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajnish%20Sharma"> Rajnish Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Anupam%20Mondal"> Anupam Mondal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Neo-adjuvant chemotherapy plays an important role in treatment of breast cancer by decreasing the tumour load and it offers an opportunity to evaluate response of primary tumour to chemotherapy. Standard anatomical imaging modalities are unable to accurately reflect the response to chemotherapy until several cycles of drug treatment have been completed. Metabolic imaging using tracers like 18F-fluorodeoxyglucose (FDG) as a marker of glucose metabolism or amino acid tracers like L-methyl-11C methionine (MET) have potential role for the measurement of treatment response. In this study, our objective was to compare these two PET tracers for assessment of response to neoadjuvant chemotherapy, in locally advanced breast carcinoma. Methods: In our prospective study, 20 female patients with histology proven locally advanced breast carcinoma underwent PET-CT imaging using FDG and MET before and after three cycles of neoadjuvant chemotherapy (CAF regimen). Thereafter, all patients were taken for MRM and the resected specimen was sent for histo-pathological analysis. Tumour response to the neoadjuvant chemotherapy was evaluated by PET-CT imaging using PERCIST criteria and correlated with histological results. Responses calculated were compared for statistical significance using paired t- test. Results: Mean SUVmax for primary lesion in FDG PET and MET PET was 15.88±11.12 and 5.01±2.14 respectively (p<0.001) and for axillary lymph nodes was 7.61±7.31 and 2.75±2.27 respectively (p=0.001). Statistically significant response in primary tumour and axilla was noted on both FDG and MET PET after three cycles of NAC. Complete response in primary tumour was seen in only 1 patient in FDG and 7 patients in MET PET (p=0.001) whereas there was no histological complete resolution of tumor in any patient. Response to therapy in axillary nodes noted on both PET scans were similar (p=0.45) and correlated well with histological findings. Conclusions: For the primary breast tumour, FDG PET has a higher sensitivity and accuracy than MET PET and for axilla both have comparable sensitivity and specificity. FDG PET shows higher target to background ratios so response is better predicted for primary breast tumour and axilla. Also, FDG-PET is widely available and has the advantage of a whole body evaluation in one study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=11C-methionine" title="11C-methionine">11C-methionine</a>, <a href="https://publications.waset.org/abstracts/search?q=18F-FDG" title=" 18F-FDG"> 18F-FDG</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20carcinoma" title=" breast carcinoma"> breast carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=neoadjuvant%20chemotherapy" title=" neoadjuvant chemotherapy"> neoadjuvant chemotherapy</a> </p> <a href="https://publications.waset.org/abstracts/1987/comparison-of-18f-fdg-and-11c-methionine-pet-ct-for-assessment-of-response-to-neoadjuvant-chemotherapy-in-locally-advanced-breast-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1987.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">510</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">137</span> Water Quality of Cengkareng Drain in Maritime Security Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Febri%20Ramadhan">Febri Ramadhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sigid%20Hariyadi"> Sigid Hariyadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Niken%20Tunjung%20Murti%20Pratiwi"> Niken Tunjung Murti Pratiwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Budiman%20Djoko%20Said"> Budiman Djoko Said</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The scope about maritime security copes all of the problems emanating from maritime domain.

Hence the pollution makes an improper condition of environments for humans and others biota dwelling in the waters. One of the tools that can determine about pollution is by measuring about the water quality of its waters. In this case, what brings the waste and pollutants is there an activity of tidal waves introducing substances or energy into the natural environment. Cengkareng Drain is one of the water channels which is affected by tidal waves. Cengkareng Drain was become an observation area to examine the relation between water quality and tide waves. This research was conducted monthly from July to November 2015. Sampling of water was conducted every ebb and tide in every observation. Pollution index showed that the level of pollution on Cengkareng drain was moderately polluted, with the score about 7.7-8.6. Based on the results of t-test and analysis of similarity, the characteristic of water quality on rising tide does not significantly differ from the characteristic of water quality on ebbing tide. Therefore, we need a proper management as a means to control the pollutants in order to make good maritime security strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maritime%20security" title="maritime security">maritime security</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengkareng%20drain" title=" Cengkareng drain"> Cengkareng drain</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=tidal%20waves" title=" tidal waves"> tidal waves</a> </p> <a href="https://publications.waset.org/abstracts/84141/water-quality-of-cengkareng-drain-in-maritime-security-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84141.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">136</span> Numerical Analysis of Prefabricated Horizontal Drain Induced Consolidation Using ABAQUS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjana%20R.%20Menon">Anjana R.

PHDs are much like Prefabricated Vertical Drains (PVDs) installed in horizontal layers, used mainly for enhancing the consolidation of clayey fill embankments, and dredged mud deposits. The efficiency of the system depends mainly on the spacing and layout of the drain. Hence, two spacing related parameters are defined, namely WH (width to horizontal spacing ratio) and VH (vertical to horizontal spacing ratio), and the finite element models are developed based on plane strain unit cell conditions under various combinations of these parameters. The analysis results, in terms of degree of consolidation (U), are compared with the established theories. Based on the analysis, a set of equations are proposed to analyse the PHD induced consolidation. The proposed method is found to be reasonably accurate. Further, the effect of PHDs at different spacing ratios, in accelerating consolidation of a clayey embankment fill is analysed in terms of pore pressure dissipation rate, and settlement. The PHD is found to accelerate the rate of pore pressure dissipation by more than 50%, thus reducing the time for final settlement significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABAQUS" title="ABAQUS">ABAQUS</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidation" title=" consolidation"> consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=plane%20strain" title=" plane strain"> plane strain</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated%20horizontal%20drain" title=" prefabricated horizontal drain"> prefabricated horizontal drain</a> </p> <a href="https://publications.waset.org/abstracts/67741/numerical-analysis-of-prefabricated-horizontal-drain-induced-consolidation-using-abaqus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67741.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">361</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">135</span> Antecedents and Impacts of Human Capital Flight in the Sub-Saharan Africa with Specific Reference to the Higher Education Sector: Conceptual Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20B.%20Gurmessa">Zelalem B.

Africa in general and Sub-Saharan African (SSA) countries, in particular, are experiencing an exodus of highly trained, qualified and competent human resources to other developing and developed countries thereby threatening the overall development of the relevant regions and impeding both public and private service delivery systems in the nation states. The region is currently in a dire situation in terms of health care services, education, science, and technology. The contribution of SSA countries to Science, Technology and Innovation is relatively minimal owing to the migration of skilled professionals due to both push and pull factors. The phenomenon calls for both international and trans-boundary, regional, national and institutional interventions to curb the exodus. Based on secondary data and the review of the literature, the article conceptualizes the antecedents and impacts of human capital flight or brain drain in the SSA countries from a higher education perspective. To this end, the article explores the magnitude, causes, and impacts of brain drain in the region. Despite the lack of consistent data on the magnitude of academic brain drain in the region, a critical analysis of the existing sources shows that pay disparity between developing and developed countries, the lack of enabling working conditions at source countries, fear of security due to political turmoil or unrest, the availability of green pastures and opportunity for development in the receiving countries were identified as major factors contributing to academic brain drain in the region. This hampers the socio-economic, technological and political development of the region. The paper also recommends that further research can be undertaken on the magnitude, causes, characteristics and impact of brain drain on the sustainability and competitiveness of SSA higher education institutions in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20drain" title="brain drain">brain drain</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-Saharan%20Africa" title=" sub-Saharan Africa"> sub-Saharan Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/71715/antecedents-and-impacts-of-human-capital-flight-in-the-sub-saharan-africa-with-specific-reference-to-the-higher-education-sector-conceptual-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71715.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">258</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">134</span> Identification of Persistent Trace Organic Pollutants in Various Waste Water Samples Using HPLC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Almas%20Hamid">Almas Hamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghazala%20Yaqub"> Ghazala Yaqub</a>, <a href="https://publications.waset.org/abstracts/search?q=Aqsa%20Riaz"> Aqsa Riaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Qualitative validation was performed to detect the presence of persistent organic pollutants (POPs) in various wastewater samples collected from domestic sources (Askari XI housing society, Bedian road Lahore) industrial sources (PET bottles, pharmaceutical, textile) and a municipal drain (Hudiara drain) in Lahore. In addition wastewater analysis of the selected parameter was carried out. pH for wastewater samples from Askari XI, PET bottles, pharmaceutical, textile and Hudiara drain were 6.9, 6.7, 6.27, 7.18 and 7.9 respectively, within the NEQS Pakistan range that is 6-9. TSS for the respective samples was 194, 241, 254, 140 and 251 mg/L, in effluent for pet bottle industry, pharmaceutical and Hudiara drain and exceeded the NEQS Pakistan. Chemical oxygen demand (COD) for the wastewater samples was 896 mg/L, 166 mg/L, 419 mg/L, 812 mg/L and 610 mg/L respectively, all in excess of NEQS (150 mg/L). Similarly the biological oxygen demand (BOD) values (110.8, 170, 423, 355 and 560 mg/L respectively) were also above NEQS limits (80 mg/L). Chloride (Cl-) content, total dissolved solids (TDS) and temperature were found out to be within the prescribed standard limits. The POPs selected for analysis included five pesticides/insecticides (D. D, Karate, Commando, Finis insect killer, Bifenthrin) and three polycyclic aromatic hydrocarbons (PAHs) (naphthalene, anthracene, phenanthrene). Peak values of standards were compared with that of wastewater samples. The results showed the presence of D.D in all wastewater samples, pesticide Karate was identified in Askari XI and textile industry sample. Pesticide Commando, Finis (insect killer) and Bifenthrin were detected in Askari XI and Hudiara drain wastewater samples. In case of PAHs; naphthalene was identified in all the five wastewater samples whereas anthracene and phenanthrene were detected in samples of Askari XI housing society, PET bottles industry, pharmaceutical industry and textile industry but totally absent in Hudiara drain wastewater. Practical recommendations have been put forth to avoid hazardous impacts of incurred samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HPLC%20studies" title="HPLC studies">HPLC studies</a>, <a href="https://publications.waset.org/abstracts/search?q=lahore" title=" lahore"> lahore</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20analysis" title=" physicochemical analysis"> physicochemical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/11765/identification-of-persistent-trace-organic-pollutants-in-various-waste-water-samples-using-hplc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11765.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">269</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">133</span> Impact on Vegetables Irrigated with Municipal and Industrial Wastewater from Korangi Drain near IoBM, Karachi </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nida%20Rabab">Nida Rabab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to assess the Impact on Vegetables Irrigated with Municipal and Industrial wastewater from Korangi Drain near IoBM, Karachi.

Method: This is a single institution retrospective review of CT-guided lung biopsies performed on 799 patients between September 2013 and May 2021 in a major tertiary hospital. Percutaneous manual aspiration of air was performed in 104/306 patients (34%) with pneumothoraxes as a preventative measure. Simple and multivariate analysis was performed to identify independent risk factors (modifiable and nonmodifiable) for the success of manual aspiration in mitigating the need for chest drain insertion. Results: The overall incidence of pneumothorax was 37% (295/799). Chest drains were inserted for 81/295 (27%) of the pneumothoraxes, representing 81/799 (10%) of all CT-guided lung biopsies. Of patients with pneumothoraces, 104 (36%) underwent percutaneous aspiration via either the coaxial guide needle or an 18 or 20G intravenous catheter attached to a three-way stopcock and syringe. Amongst this group, 13 patients (13%) subsequently required chest drain insertion. The success of percutaneous aspiration in avoiding subsequent pleural drain insertion decreased with aspiration volume >500mL, radial pneumothorax depth >3cm, increased subpleural depth of the lesion, and the presence of background emphysema. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography" title="computed tomography">computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20biopsy" title=" lung biopsy"> lung biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumothorax" title=" pneumothorax"> pneumothorax</a>, <a href="https://publications.waset.org/abstracts/search?q=manual%20aspiration" title=" manual aspiration"> manual aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20drainage" title=" chest drainage"> chest drainage</a> </p> <a href="https://publications.waset.org/abstracts/140907/the-usefulness-and-limitations-of-manual-aspiration-immediately-after-pneumothorax-complicating-percutaneous-ct-guided-lung-biopsies-a-retrospective-9-year-review-from-a-large-tertiary-centre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140907.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">175</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">130</span> The Net as a Living Experience of Distance Motherhood within Italian Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Papapicco">C.

Nambiar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Surgery for breast cancer is either mastectomy or breast conservation surgery. The most commonly used incision for modified radical mastectomy is the transverse Stewart incision. But this incision may have the disadvantage of causing disparity between the closure lines of superior and inferior skin flaps in mastectomy and can cause overhanging of soft tissue below and behind the axilla. The curvizigzag incision, on principle, may help in this regard and can prevent scar migration beyond the anterior axillary line. This study aims to compare the two incisions in this regard. Methods: 100 patients with cancer of breast were included in the study after satisfying inclusion and exclusion criteria. They underwent surgery at Father Muller Medical College, Mangalore, India, between November 2019 to September 2021. The patients were divided into two groups. Group A patients were subjected to modified radical mastectomy with curvizigzag incision and group B patients with transverse Stewart incision. Results: Seroma on postoperative day1, day 2 was 0% in both the groups. Seroma on postoperative day 30 was present in 14% of patients in group B. 60% of patients in group B had sag of soft tissue below and behind the axilla, and none of the patients in group A had this problem. In 64% of the patients in group B, the incision crossed the anterior axillary fold, 64% of the patients in group B had tension in the incision site while approximation of the skin flaps. Conclusion: Curvizigzag incision is statistically better with lesser complications when compared to the transverse Stewart incision for modified radical mastectomy for carcinoma breast. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=curvizigzag%20incision" title=" curvizigzag incision"> curvizigzag incision</a>, <a href="https://publications.waset.org/abstracts/search?q=transverse%20Stewart%20incision" title=" transverse Stewart incision"> transverse Stewart incision</a>, <a href="https://publications.waset.org/abstracts/search?q=seroma" title=" seroma"> seroma</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20radical%20mastectomy" title=" modified radical mastectomy"> modified radical mastectomy</a> </p> <a href="https://publications.waset.org/abstracts/153834/comparison-of-the-curvizigzag-incision-with-transverse-stewart-incision-in-women-undergoing-modified-radical-mastectomy-for-carcinoma-breast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153834.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">95</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">128</span> Characteristics of Silicon Integrated Vertical Carbon Nanotube Field-Effect Transistors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingqi%20Li">Jingqi Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new vertical carbon nanotube field effect transistor (CNTFET) has been developed.

The significant advantage of this CNTFET is that the short channel of the transistor can be fabricated without using complicate lithography technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title="carbon nanotubes">carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=field-effect%20transistors" title=" field-effect transistors"> field-effect transistors</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20property" title=" electrical property"> electrical property</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20channel%20fabrication" title=" short channel fabrication"> short channel fabrication</a> </p> <a href="https://publications.waset.org/abstracts/82705/characteristics-of-silicon-integrated-vertical-carbon-nanotube-field-effect-transistors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82705.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">361</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">127</span> A Measurement Device of Condensing Flow Rate, an Order of MilliGrams per Second</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hee%20Joon%20Lee">Hee Joon Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are many difficulties in measuring a small flow rate of an order of milli grams per minute (LPM) or less using a conventional flowmeter. Therefore, a flow meter with minimal loss and based on a new concept was designed as part of this paper. A chamber was manufactured with a level transmitter and an on-off control valve. When the level of the collected condensed water reaches the top of the chamber, the valve opens to allow the collected water to drain back into the tank. To allow the water to continue to drain when the signal is lost, the valve is held open for a few seconds by a time delay switch and then closed. After an examination, the condensing flow rate was successfully measured with the uncertainty of ±5.7% of the full scale for the chamber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chamber" title="chamber">chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=condensation" title=" condensation"> condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20meter" title=" flow meter"> flow meter</a>, <a href="https://publications.waset.org/abstracts/search?q=milli-grams" title=" milli-grams"> milli-grams</a> </p> <a href="https://publications.waset.org/abstracts/48842/a-measurement-device-of-condensing-flow-rate-an-order-of-milligrams-per-second" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48842.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">281</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">126</span> A Genetic-Neural-Network Modeling Approach for Self-Heating in GaN High Electron Mobility Transistors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anwar%20Jarndal">Anwar Jarndal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a genetic-neural-network (GNN) based large-signal model for GaN HEMTs is presented along with its parameters extraction procedure.

Two GNN models are constructed to simulate isothermal drain current and power dissipation, respectively. The two model are then composed to simulate the drain current. The modeling procedure was applied to a packaged GaN-on-Si HEMT and the developed model is validated by comparing its large-signal simulation with measured data.

The Al₂O₃ gate oxide was formed by using a cost-effective non-vacuum ultrasonic spray pyrolysis deposition (USPD) method. In order to enhance the heat dissipation efficiency, metal trenches were etched 3-µm deep and evaporated with a 150-nm thick Ni film on the backside of the Si substrate. The present In₀.₁₈Al₀.₈₂N/AlN/GaN MOS-HFET (Schottky-gate HFET) has demonstrated improved maximum drain-source current density (IDS, max) of 1.08 (0.86) A/mm at VDS = 8 V, gate-voltage swing (GVS) of 4 (2) V, on/off-current ratio (Ion/Ioff) of 8.9 × 10⁸ (7.4 × 10⁴), subthreshold swing (SS) of 140 (244) mV/dec, two-terminal off-state gate-drain breakdown voltage (BVGD) of -191.1 (-173.8) V, turn-on voltage (Von) of 4.2 (1.2) V, and three-terminal on-state drain-source breakdown voltage (BVDS) of 155.9 (98.5) V. Enhanced power performances, including saturated output power (Pout) of 27.9 (21.5) dBm, power gain (Gₐ) of 20.3 (15.5) dB, and power-added efficiency (PAE) of 44.3% (34.8%), are obtained.

Due to the Eastern European countries joining the EU and the opening of the Western European labour market the west-wards migration brisked up. By now another problem has been intensified correlated to migration: the migration of highly skilled workers related to brain waste tendencies. With some exceptions, educated immigrants from Eastern European countries are more likely to end up in unskilled jobs than residents. This paper is about to reveal the above-mentioned problems and this study is supported by the results of secondary pieces of research and the own survey made in the EU-15 among the Hungarian highly skilled (especially economics graduated) migrants, and it also examines the causes and in the focus there are the migrant motivations of the high-skilled young generation after the crisis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20drain" title="brain drain">brain drain</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20waste" title=" brain waste"> brain waste</a>, <a href="https://publications.waset.org/abstracts/search?q=migration%20of%20highly-skilled" title=" migration of highly-skilled"> migration of highly-skilled</a>, <a href="https://publications.waset.org/abstracts/search?q=underemployment" title=" underemployment"> underemployment</a> </p> <a href="https://publications.waset.org/abstracts/50044/highly-skilled-migrants-trapped-in-the-brain-waste-the-eastern-european-graduates-in-the-western-european-underemployment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50044.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">121</span> The Dual Catastrophe of Behçet’s Disease Visual Loss Followed by Acute Spinal Shock After Lumbar Drain Removal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naim%20Izet%20Kajtazi">Naim Izet Kajtazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context: Increased intracranial pressure and associated symptoms such as headache, papilledema, motor or sensory deficits, seizures, and conscious disturbance are well-known in acute CVT. However, visual loss is not commonly associated with this disease, except in the case of secondary IIH associated with it. Process: We report a case of a 40-year-old male with Behçet’s disease and cerebral venous thrombosis, and other multiple comorbidities admitted with a four-day history of increasing headache and rapidly progressive visual loss bilaterally. The neurological examination was positive for bilateral papilledema of grade 3 with light perception on the left eye and counting fingers on the right eye. Brain imaging showed old findings of cerebral venous thrombosis without any intraparenchymal lesions to suggest a flare-up of Behçet’s disease. The lumbar puncture, followed by the lumbar drain insertion, gave no benefit in headache or vision. However, he completely lost sight. The right optic nerve sheath fenestration did not result in vision improvement. The acute spinal shock complicated the lumbar drain removal due to epidural hematoma. An urgent lumbar laminectomy with hematoma evacuation undertook. Intra-operatively, the neurosurgeon noted suspicious abnormal vessels at conus medullaris with the possibility of an arteriovenous malformation. Outcome: In a few days following the spinal surgery, the patient vision started to improve. Further improvement was achieved after plasma exchange sessions followed by cyclophosphamide. In the recent follow-up in the clinic, he reported better vision, drove, and completed his Ph.D. studies. Relevance: Visual loss in patients with Behçet’s disease should always be anticipated and taken reasonable care of, ensuring that they receive well-combined immunosuppression with anticoagulation and agents to reduce intracranial pressure. This patient’s story is significant for a high disease burden and complicated hospital course by acute spinal shock due to spinal lumbar drain removal with a possible underlying spinal arteriovenous malformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behcet%20disease" title="Behcet disease">Behcet disease</a>, <a href="https://publications.waset.org/abstracts/search?q=optic%20neuritis" title=" optic neuritis"> optic neuritis</a>, <a href="https://publications.waset.org/abstracts/search?q=IIH" title=" IIH"> IIH</a>, <a href="https://publications.waset.org/abstracts/search?q=CVT" title=" CVT"> CVT</a> </p> <a href="https://publications.waset.org/abstracts/160866/the-dual-catastrophe-of-behcets-disease-visual-loss-followed-by-acute-spinal-shock-after-lumbar-drain-removal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160866.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">73</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">120</span> On-Plot Piping Corrosion Analysis for Gas and Oil Separation Plants (GOSPs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sultan%20A.%20Al%20Shaqaq">Sultan A.

Two GOSPs (Plant-A and Plant-B) observed chronic corrosion issue with an on-plot piping system that leads to having more piping replacement during the past years. Since it is almost impossible to avoid corrosion, it is becoming more obvious that managing the corrosion level may be the most economical resolution. Corrosion engineers are thus increasingly involved in approximating the cost of their answers to corrosion prevention, and assessing the useful life of the equipment. This case study covers the background of corrosion encountered in piping internally and externally in these two GOSPs. The collected piping replacement data from year of 2011 to 2014 was covered. These data showed the replicate corrosion levels in an on-plot piping system.

The development of the small-signal admittance takes into account the longitudinal and transverse electric fields through a pseudo two-dimensional approximation of the Poisson equation. The total currents and the potentials matrix relation between the gate and the drain terminals determine the frequency-dependent small-signal admittance response. The analytical results show that the admittance spectrum exhibits a series of resonant peaks corresponding to the excitation of plasma waves. The appearance of the resonance is discussed and analyzed as functions of the channel length and the temperature. The model can be used, on one hand, to control the appearance of plasma resonances, and on the other hand, can give significant information about the admittance phase frequency dependence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small-signal%20admittance" title="small-signal admittance">small-signal admittance</a>, <a href="https://publications.waset.org/abstracts/search?q=Poisson%20equation" title=" Poisson equation"> Poisson equation</a>, <a href="https://publications.waset.org/abstracts/search?q=currents%20and%20potentials%20matrix" title=" currents and potentials matrix"> currents and potentials matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20drain%20and%20the%20gate%20terminals" title=" the drain and the gate terminals"> the drain and the gate terminals</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title=" analytical model"> analytical model</a> </p> <a href="https://publications.waset.org/abstracts/35861/analytical-response-characterization-of-high-mobility-transistor-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35861.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">540</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">117</span> Impact on Soil Irrigated with Municipal and Industrial Wastewater from Korangi Drain near IoBM, Karachi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Ali">Farhan Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Use of wastewater for growing vegetables has become a common practice around big cities. Wastewater contains organic material and inorganic elements essential for plant growth but also contain heavy metals, which may be lethal for animals and humans if their concentration increases than permissible limit. To monitor this situation, a survey was conducted to ascertain the addition of heavy metals into agricultural fields through wastewater irrigation and their translocation in to the edible parts of the vegetables. The study highlighted that there is a large accumulation of heavy metals in the soil, which is irrigated with industrial wastewater Laden and people consume vegetables grown in soil irrigated with sewage water to absorb a large amount of these metals. This accumulation of heavy metals in food cause possible health risks for the consumer. Regular monitoring of the levels of pathogens and heavy metals from the waste water drain which effluent are used for growing vegetables and other foodstuffs is essential to monitor excessive accumulation of these metals in the food chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pathogens" title="pathogens">pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=effluent" title=" effluent"> effluent</a> </p> <a href="https://publications.waset.org/abstracts/32592/impact-on-soil-irrigated-with-municipal-and-industrial-wastewater-from-korangi-drain-near-iobm-karachi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32592.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">297</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">116</span> Quantification of River Ravi Pollution and Oxidation Pond Treatment to Improve the Drain Water Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusra%20Mahfooz">Yusra Mahfooz</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleha%20Mehmood"> Saleha Mehmood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With increase in industrialization and urbanization, water contaminating rivers through effluents laden with diverse chemicals in developing countries. The study was based on the waste water quality of the four drains (Outfall, Gulshan -e- Ravi, Hudiara, and Babu Sabu) which enter into river Ravi in Lahore, Pakistan. Different pollution parameters were analyzed including pH, DO, BOD, COD, turbidity, EC, TSS, nitrates, phosphates, sulfates and fecal coliform. Approximately all the water parameters of drains were exceeded the permissible level of wastewater standards. In calculation of pollution load, Hudiara drains showed highest pollution load in terms of COD i.e. 429.86 tons/day while in Babu Sabu drain highest pollution load was calculated in terms of BOD i.e. 162.82 tons/day (due to industrial and sewage discharge in it). Lab scale treatment (oxidation ponds) was designed in order to treat the waste water of Babu Sabu drain, through combination of different algae species i.e. chaetomorphasutoria, sirogoniumsticticum and zygnema sp. Two different sizes of ponds (horizontal and vertical), and three different concentration of algal samples (25g/3L, 50g/3L, and 75g/3L) were selected. After 6 days of treatment, 80 to 97% removal efficiency was found in the pollution parameters. It was observed that in the vertical pond, maximum reduction achieved i.e. turbidity 62.12%, EC 79.3%, BOD 86.6%, COD 79.72%, FC 100%, nitrates 89.6%, sulphates 96.9% and phosphates 85.3%. While in the horizontal pond, the maximum reduction in pollutant parameters, turbidity 69.79%, EC 83%, BOD 88.5%, COD 83.01%, FC 100%, nitrates 89.8%, sulphates 97% and phosphates 86.3% was observed. Overall treatment showed that maximum reduction was carried out in 50g algae setup in the horizontal pond due to large surface area, after 6 days of treatment. Results concluded that algae-based treatment are most energy efficient, which can improve drains water quality in cost effective manners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxidation%20pond" title="oxidation pond">oxidation pond</a>, <a href="https://publications.waset.org/abstracts/search?q=ravi%20pollution" title=" ravi pollution"> ravi pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20water%20quality" title=" river water quality"> river water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a> </p> <a href="https://publications.waset.org/abstracts/61616/quantification-of-river-ravi-pollution-and-oxidation-pond-treatment-to-improve-the-drain-water-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61616.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">298</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">115</span> Soft Ground Improved by Prefabricated Vertical Drains with Vacuum and Thermal Preloading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gia%20Lam%20Le">Gia Lam Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Dennis%20T.%20Bergado"> Dennis T.

Large-scale consolidations of reconstituted soft Bangkok clay were conducted for PVD improvement with vacuum (vacuum-PVD), and vacuum combined with heat (vacuum-thermo-PVD). The research revealed that vacuum-thermo-PVD gives high efficiency of the consolidation rate compared to the vacuum-PVD. In addition, the magnitude of settlement of the specimen improved by the vacuum-thermo-PVD is higher than the vacuum-PVD because the assistance of heat causes the collapse of the clay structure. Particularly, to reach 90% degree of consolidation, the thermal-vacuum-PVD reduced about 58% consolidation time compared to the vacuum-PVD. The increase in consolidation rate is resulted from the increase in horizontal coefficient of consolidation, Ch, the reduction of the smear effect expressed by the ratio of the horizontal hydraulic conductivity in the undisturbed zone, kh, and the horizontal hydraulic conductivity in the smeared zone, ks. Furthermore, the shear strength, Su, increased about 100% when compared using the vacuum-thermal-PVD to the vacuum PVD. In addition, numerical simulations gave reasonable results compared to the laboratory data. <p class="card-text"><strong>Keywords:</strong> <a
