It was presently in any Islamic financial transactions in order to comply with shariah rules. However, the existence of risk in Murabahah contract of financing is an ability that the counterparty is unable to complete its obligations within the agreed terms. Therefore, it is called as credit or default risk. Credit risk occurs when the client fails to make timely payment after the bank makes complete delivery of assets. Thus, it affects the growth of the bank as the banking business is in no position to have appropriate measures to cover the risk. Therefore, the bank may impose penalty on the outstanding balance. This paper aims to highlight the credit risk determinant and issues surrounding in Islamic bank in Malaysia in terms of Murabahah financing and how to manage it by using the proper techniques. Finally, it explores the credit risk management concept that might solve the problems arise. The study found that the credit risk can be managed properly by improving the use of comprehensive reference checklist of business partners on their character and past performance as well as their comprehensive database. Besides that, prevention of credit risk can be done by using collateral as security against the risk and we also argue on the Shariah guidelines and procedures should be implement coherently by the banking business because so that the risk would be control by having an effective instrument for Islamic modes of financing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banking" title="Islamic banking">Islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20risk" title=" credit risk"> credit risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Murabahah%20financing" title=" Murabahah financing"> Murabahah financing</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20mitigation" title=" risk mitigation"> risk mitigation</a> </p> <a href="https://publications.waset.org/abstracts/6911/islamic-credit-risk-management-in-murabahah-financing-the-study-of-islamic-banking-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6911.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">456</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">79</span> Enhanced Ripening Behaviour of Manganese Doped Cadmium Selenide Quantum Dots (Mn-doped CdSe QDs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20A.%20Hamizi">N.

It seems that a few Egyptian architects suffer from the lack of the ability to create and share knowledge in their field of proficiency. The assumption is that this weakness is the main reason that led to the invalidity of the local theorizing process. The presupposition is that the absence of respecting the conceptualization of enlightenment during the two phases of preparing and teaching the educational programs makes the students urban design projects not well designed. This paper submits an Egyptian Manifesto, to formulate some guidelines for the development of the work of some researchers, scholars and specialist's method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20manifesto" title="Egyptian manifesto">Egyptian manifesto</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20design" title=" urban design"> urban design</a> </p> <a href="https://publications.waset.org/abstracts/30367/interdisciplinary-urban-design-toward-egyptian-manifesto" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30367.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">456</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">77</span> Maximum Efficiency of the Photovoltaic Cells Using a Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latifa%20Sabri">Latifa Sabri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Benzirar"> Mohammed Benzirar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mimoun%20Zazoui"> Mimoun Zazoui </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The installation of photovoltaic systems is one of future sources to generate electricity without emitting pollutants. The photovoltaic cells used in these systems have demonstrated enormous efficiencies and advantages. Several researches have discussed the maximum efficiency of these technologies, but only a few experiences have succeeded to right weather conditions to get these results. In this paper, two types of cells were selected: crystalline and amorphous silicon. Using the method of genetic algorithm, the results show that for an ambient temperature of 25°C and direct irradiation of 625 W/m², the efficiency of crystalline silicon is 12% and 5% for amorphous silicon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PV" title="PV">PV</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20efficiency" title=" maximum efficiency"> maximum efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title=" solar cell"> solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/43781/maximum-efficiency-of-the-photovoltaic-cells-using-a-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43781.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">424</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">76</span> Regional Pole Placement by Saturated Power System Stabilizers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hisham%20M.%20Soliman">Hisham M.

Several general solutions have been proposed in the past, but these are largely computationally intensive, leading to complex implementations. In this paper, we propose a relatively simple iterative solution, which provides good results in relatively few iterations, using fixed precision arithmetic. An additional advantage is that complex digital blocks, such as dividers and square root, are not required. Thus, the proposed solution may be implemented in relatively simple hardware. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OFDM" title="OFDM">OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=DVB-T2" title=" DVB-T2"> DVB-T2</a>, <a href="https://publications.waset.org/abstracts/search?q=I%2FQ%20imbalance" title=" I/Q imbalance"> I/Q imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=I%2FQ%20mismatch" title=" I/Q mismatch"> I/Q mismatch</a>, <a href="https://publications.waset.org/abstracts/search?q=iterative%20method" title=" iterative method"> iterative method</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed%20point" title=" fixed point"> fixed point</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20complexity" title=" reduced complexity"> reduced complexity</a> </p> <a href="https://publications.waset.org/abstracts/1821/reduced-complexity-iterative-solution-for-iq-imbalance-problem-in-dvb-t2-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1821.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">541</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">74</span> Physicochemical Characterization of Mercerized Cellulose-Supported Nickel-Oxide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sherif%20M.%20A.%20S.%20Keshk">Sherif M.

The resulting wrinkling patterns, their amplitude and their wavelengths under the prescribed loads and boundary conditions were confirmed by experimental results. Our study reveals that wrinkles develop when both the magnitudes and coverage of the minimum principal stresses in the laminated composite laminates are sufficiently large to trigger wrinkling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane" title=" membrane"> membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=wrinkling" title=" wrinkling"> wrinkling</a> </p> <a href="https://publications.waset.org/abstracts/88781/wrinkling-prediction-of-membrane-composite-of-varying-orientation-under-in-plane-shear" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">71</span> New Coordinate System for Countries with Big Territories</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sabri%20Ali%20Akresh">Mohammed Sabri Ali Akresh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The modern technologies and developments in computer and Global Positioning System (GPS) as well as Geographic Information System (GIS) and total station TS.

R2 with a given accession number DQ 923161. This strain was able to produce high levels of extracellular chitinase. The chitinase of Bacillus sp. R2 hydrolyzed several chitinous substrates preferentially and showed a maximum activity toward the β chitin such as Calmar pen and squid bone chitins with the folds 1.47 and 1.23 respectively. The enzyme also exhibited a substrate binding capacity of more than 70% for squid chitin, shrimp shell colloidal chitin, chitosan and prawn shell chitin.

The insecure street environment exposes street children into various risk factors. One of them is the health and psychological problem. The objective of this study is to assess the health problem and psychological wellbeing of street children in Kuala Lumpur, Malaysia. The cross-sectional study involved 303 street children in Chow Kit, Kuala Lumpur. The study confirmed that the majority (95.7%) of street children who participated in the study have a health problem. The findings also demonstrated that the majority of them have issues related to their psychological wellbeing. The inputs from this study are instrumental for the suggestion of specific intervention to improve the health and psychology wellbeing of street children in Malaysia. Agencies which are responsible for the street children well-being can utilise the inputs to framing and improving the social care programmes for the children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=street%20children" title="street children">street children</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20status" title=" health status"> health status</a>, <a href="https://publications.waset.org/abstracts/search?q=psychology%20wellbeing" title=" psychology wellbeing"> psychology wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=homeless" title=" homeless"> homeless</a> </p> <a href="https://publications.waset.org/abstracts/107193/health-status-and-psychology-wellbeing-of-street-children-in-kuala-lumpur" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107193.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">183</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">59</span> Effect of Chemical Modifier on the Properties of Polypropylene (PP) / Coconut Fiber (CF) in Automotive Application </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shahril">K.

The mechanical testing indicates that composite with 10 wt% of untreated composite has the optimum value of tensile strength, and the composite with chemical modifier shows the tensile strength was increased. By increasing of filler loading, elastic modulus was increased while the elongation at brake was decreased. Meanwhile, the swelling test discerned that the increase of filler loading increased the water absorption of composites and the presence of chemical modifier reduced the equilibrium water absorption percentage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coconut%20fiber" title="coconut fiber">coconut fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20acrylic" title=" acid acrylic"> acid acrylic</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20modifier" title=" chemical modifier"> chemical modifier</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a> </p> <a href="https://publications.waset.org/abstracts/14842/effect-of-chemical-modifier-on-the-properties-of-polypropylene-pp-coconut-fiber-cf-in-automotive-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14842.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">461</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Optimization of Passive Vibration Damping of Space Structures </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20Askar">Emad Askar</a>, <a href="https://publications.waset.org/abstracts/search?q=Eldesoky%20Elsoaly"> Eldesoky Elsoaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Kamel"> Mohamed Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hisham%20Kamel"> Hisham Kamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this article is to improve the passive vibration damping of solar array (SA) used in space structures, by the effective application of numerical optimization.

Market analysis also identify market trends, demographics, customer’s buying habits and important information on the competition. Data mining is used instead of traditional research, because it extracts predictive information about customer and sales from large databases. In contrast to traditional research, data mining relies on information that is already available. Simply the goal is to improve the efficiency of supermarkets. In this study, the purpose is to find dependency on products. For instance, which items are bought together, using association rules in data mining.

This technique is the principle of additional heating (ECRH) and the generation of non-inductive current drive (ECCD) in modern fusion devices. In this paper we are interested by the problem of EC absorption which used a microscopic description of kinetic theory treatment versus the propagation which used the cold plasma description. The power absorbed depends on the optical depth which in turn depends on coefficient of absorption and the order of the excited harmonic for O-mode or X-mode. There is another possibility of heating by dissipation of Alfven waves, based on resonance of cold plasma waves, the shear Alfven wave (SW) and the compressional Alfven wave (FW). Once the (FW) power is coupled to (SW), it stays on the magnetic surface and dissipates there, which cause the heating of bulk plasmas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electron%20cyclotron" title="electron cyclotron">electron cyclotron</a>, <a href="https://publications.waset.org/abstracts/search?q=heating" title=" heating"> heating</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma" title=" plasma"> plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=tokamak" title=" tokamak"> tokamak</a> </p> <a href="https://publications.waset.org/abstracts/30668/the-plasma-additional-heating-systems-by-electron-cyclotron-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30668.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">513</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">55</span> Preliminary Geotechnical Properties of Uncemented Sandstone Kati Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nursyafiqah%20Abdul%20Kahar">Nursyafiqah Abdul Kahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Niraku%20Rosmawati%20Ahmad"> Niraku Rosmawati Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Hisham%20Mohamad"> Hisham Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nuruljannah%20Mohd%20Marzuki"> Siti Nuruljannah Mohd Marzuki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assessment of geotechnical properties of the subsoil is necessary for generating relevant input for the design and construction of a foundation.

The focus of this research is to investigate the preliminary geotechnical properties of the uncemented sandstone from Kati formation at Puncak Iskandar, Seri Iskandar. A series of basic soil tests, oedometer and direct shear box tests were carried out to obtain the soil parameters. The uncemented sandstone of Kati Formation was found to have well-graded and poorly graded sand distribution, depending on the location where the samples were obtained. The sand grains distribution was in a range of 82%-100% while, the specific gravity of the uncemented sandstone is in the range 2.65-2.86. The preconsolidation pressure for USB3 was 990 kPa indicating that the sandstone at USB3 sample had undergone 990 kPa of overburden pressure. The angle of friction for uncemented sandstone was ranging between 23.34°-32.92°. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geotechnical%20properties" title="geotechnical properties">geotechnical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Kati%20formation" title=" Kati formation"> Kati formation</a>, <a href="https://publications.waset.org/abstracts/search?q=uncemented%20sandstone" title=" uncemented sandstone"> uncemented sandstone</a>, <a href="https://publications.waset.org/abstracts/search?q=oedometer%20test%3B%20shear%20box%20test" title=" oedometer test; shear box test"> oedometer test; shear box test</a> </p> <a href="https://publications.waset.org/abstracts/131980/preliminary-geotechnical-properties-of-uncemented-sandstone-kati-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131980.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Numerical Analysis of Various V- rib Cross-section to Optimize Thermal Performance of the Rocket Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hisham%20Elmouazen">Hisham Elmouazen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaobing%20Zhang"> Xiaobing Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In regenerative-cooled rocket engines, understanding the coolant behaviour within cooling channels is essential to enhance engine performance and maintain chamber walls at low temperatures. However, modelling and testing the rocket engine's cooling channels is challenging due to the high temperature of the chamber walls, supercritical flow, and high Reynolds number. Therefore, a numerical analysis of five different V-rib cross-sections to optimize rocket engine cooling channels' performance is developed and validated in this work. Three-dimensional CFD simulations are employed by the Shear Stress Transport (k- ω) turbulent model at Reynolds number 42,500. The study findings illustrate that the V-ribbed channel performance is optimized by 59.5% relative to the plain/flat channel. Additionally, the chamber wall temperature is decreased to 726.4 K, and the right-angle trapezoidal V-rib (Case 4) improves thermal augmentation up to 74.3 % with a slightly high friction factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics%20CFD" title="computational fluid dynamics CFD">computational fluid dynamics CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative-cooled%20system" title=" regenerative-cooled system"> regenerative-cooled system</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20performance" title=" thermal performance"> thermal performance</a>, <a href="https://publications.waset.org/abstracts/search?q=V-rib%20cross-sections" title=" V-rib cross-sections"> V-rib cross-sections</a> </p> <a href="https://publications.waset.org/abstracts/163876/numerical-analysis-of-various-v-rib-cross-section-to-optimize-thermal-performance-of-the-rocket-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163876.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">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Assessing Secondary School Curricula in the light of Developing Quality of Life Standards of High School Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Othman%20Ali%20Alghtani">Othman Ali Alghtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Abdul-Ekhalq%20Ali"> Yahya Abdul-Ekhalq Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Abdul-Ekhalq%20Ali"> Abdullah Abdul-Ekhalq Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al%20Sadiq%20Abdul%20Majeed"> Ahmed Al Sadiq Abdul Majeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Najwa%20Attian%20Al-Mohammadi"> Najwa Attian Al-Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Obead%20Mozel%20Alharbi"> Obead Mozel Alharbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabri%20Mohamed%20Ismail"> Sabri Mohamed Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Ibrahim%20Asiri"> Omar Ibrahim Asiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study assessed the curricula of secondary schools given requirements to enhance the quality of life of students.

By utilizing medical image data, medical professionals can obtain detailed information about a patient's injuries, enabling them to conduct a thorough preoperative assessment while ensuring the implant's accuracy. However, selecting the right implant material requires careful consideration of various mechanical properties. This study aims to compare the two commonly used implant material for cranial reconstruction which includes titanium (Ti6Al4V) and Polyetheretherketone (PEEK). Biomechanical analysis was performed to study the implant behavior, by keeping the implant design and fixation constant in both cases. A finite element model was created and analyzed under loading conditions. The finite element analysis proves that although Ti6Al4V is stronger than PEEK but, its mechanical strength is adequate to bear the loads of the adjacent bone tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cranial%20reconstruction" title="cranial reconstruction">cranial reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20implants" title=" titanium implants"> titanium implants</a>, <a href="https://publications.waset.org/abstracts/search?q=PEEK" title=" PEEK"> PEEK</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a> </p> <a href="https://publications.waset.org/abstracts/177711/comparative-study-of-titanium-and-polyetheretherketone-cranial-implant-using-finite-element-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177711.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">68</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">51</span> Consumers Rights during COVID-19 Pandemic Time: Evidence from Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabri%20Gabran%20Mohammed%20Elkrghli">Sabri Gabran Mohammed Elkrghli</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20A.%20Mohamed%20Abdulgader"> Salah A.

Libyan consumers have been targeted in this study with the aim to measure their attitudes towards the extent to which their rights, as consumers of foodstuff, have been secured during the Covid-19 pandemic. The recommended sample size was randomly selected (384) local participants. Out of this number, only a validated number of (267) responses were deemed valid for the analysis phase. The instrument of this research was developed based on the extant published literature on consumer rights. The study concluded with a set of key results; the most important result is that consumer rights of foodstuffs were below the satisfactory level. Theoretical and practical implications have emerged from the study. The most important implication is that customers of foodstuffs need more protection in Libya. This issue should be given greater importance, especially in the light of contemporary environmental challenges such as the outbreak of Covid-19. Designing and conducting global and local awareness campaigns is another significant advice suggested by this study.
