This paper focuses on the geometric-mass inertia modeling and the actuation system modeling for the small fixed-wing UAVs. The UAV geometric parameters for the body, wing, horizontal and vertical tail are physically measured. Pendulum experiment with high-grade sensors and data analysis using MATLAB is used to estimate the airplane moment of inertia (MOI) model. Finally, UAV’s actuation system is modeled by estimating each servo transfer function by using the system identification, which uses experimental measurement for input and output angles through using field-programmable gate array (FPGA). Experimental results for the designed models are given to illustrate the effectiveness of the methodology. It also gives a very promising result to finalize the open-loop flight simulation model through modeling the propulsion system and the aerodynamic system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title="unmanned aerial vehicle">unmanned aerial vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric-mass%20inertia%20model" title=" geometric-mass inertia model"> geometric-mass inertia model</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20identification" title=" system identification"> system identification</a>, <a href="https://publications.waset.org/abstracts/search?q=Simulink" title=" Simulink"> Simulink</a> </p> <a href="https://publications.waset.org/abstracts/142165/small-fixed-wing-uav-physical-based-modeling-simulation-and-validation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142165.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">179</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">41</span> Contraception in Schizophrenia Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Puspa%20Maharani">Puspa Maharani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hendy%20Muagiri%20Margono"> Hendy Muagiri Margono</a>, <a href="https://publications.waset.org/abstracts/search?q=Izzatul%20Fithriyah"> Izzatul Fithriyah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contraception is a medium used to prevent conception, aimed at couples who do not want pregnancy to occur. Unintended pregnancies have a prevalence of 48% per year of the total pregnancies that occur throughout the world. Schizophrenia sufferers have a high probability of being involved in unwanted sexual relations, but are not supported by adequate knowledge and use of contraception, so they are vulnerable to experiencing unwanted pregnancies. Unwanted pregnancy can pose significant health risks for patients with schizophrenia. There are many types of contraception that can be discussed and considered for patients with schizophrenia in order to improve the quality and well- being of their lives. Choosing the right contraceptive for patients with schizophrenia requires consideration of its use by taking into account the many factors that influence it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schizophrenia" title="schizophrenia">schizophrenia</a>, <a href="https://publications.waset.org/abstracts/search?q=contraception" title=" contraception"> contraception</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a> </p> <a href="https://publications.waset.org/abstracts/189317/contraception-in-schizophrenia-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189317.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">20</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">40</span> Performance Investigation of UAV Attitude Control Based on Modified PI-D and Nonlinear Dynamic Inversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Hassan%20Kapeel">Ebrahim Hassan Kapeel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mohsen%20Kamel"> Ahmed Mohsen Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossan%20Hendy"> Hossan Hendy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yehia%20Z.%20Elhalwagy"> Yehia Z.

So it is necessary to find the factors that influence the occurrence of complications. Methods: This is a retrospective cross-sectional analytic study in Cipto Mangunkusumo Hospital noting medical records of patients after the colostomy from January 2012 to December 2014 at the Division of Digestive Surgery. Results: In 136 cases of post-colostomy, 66 cases have complications, 14 is early-onset, and 52 is late-onset. 70 is without complications. Most complications are dermatitis, which is 31 (22.8%), cases of infection/abscess/fistula and intestinal obstruction are 13 (9.6%) and 5 patients (4.4%). A rare complication is colostomy retraction by 2 patients (1.5%), colostomy prolapse and necrosis/gangrene, which is only 3 patients (2.2%). A colostomy procedure in emergency surgery is riskier than elective surgery for complications after colostomy (p < 0.007, OR 2.85), Based on the operator who performs a colostomy procedure, the consultant had a lower risk of complications than fellow or resident (p < 0.0001). Based on the age factor, where the age of about 50 years has a risk of complications after colostomy (p < 0.018). Conclusion: The timing of operation (emergency or elective), age, and operator who perform a colostomy procedure have a significant relationship with an increased prevalence of complications after colostomy in RSCM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colostomy" title="colostomy">colostomy</a>, <a href="https://publications.waset.org/abstracts/search?q=complications" title=" complications"> complications</a>, <a href="https://publications.waset.org/abstracts/search?q=factors" title=" factors"> factors</a>, <a href="https://publications.waset.org/abstracts/search?q=procedure" title=" procedure"> procedure</a> </p> <a href="https://publications.waset.org/abstracts/52406/evaluation-of-complications-after-colostomy-procedure-and-related-factors-in-cipto-mangunkusumo-hospital-since-2012-2014" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52406.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">270</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">38</span> Evaluation of Chromium Fortified-Parboiled Rice Coated with Herbal Extracts: Resistant Starch, and Glycemic Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wisnu%20Adi%20Yulianto">Wisnu Adi Yulianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Chatarina%20%20Lilis%20Suryani"> Chatarina Lilis Suryani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamilisti%20Susiati"> Mamilisti Susiati</a>, <a href="https://publications.waset.org/abstracts/search?q=Hendy%20Indra%20Permana"> Hendy Indra Permana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parboiled rice was developed to produce rice that has low glycemic index, especially for diabetics. Yet, parboiled rice is not enough because diabetics also lack of chromium. The sign of chromium (Cr) deficiency in diabetics is impaired glucose tolerance. Cr fortification was done for increasing Cr content in rice. Naturally-occurring compounds that have been proven to improve insulin sensitivity include Cr and polyphenol found in cinnamon, pandan and bay leaf. This research aimed to evaluate content of resistant starch and glycemic index of Cr - fortified - parboiled rice (Cr-PR) coated with herbal extracts. Variety of unhulled rice and forticant used in the experiment were Ciherang and CrCl3, respectively. Three herbal extracts used were cinnamon, pandan and bay leaf. Each concentration of herbal extracts in the amount of 3%, 6%, and 9% were added in the coating substance to coat Cr-PR. Resistant starch (RS) content was determined by enzymatic process through glucooxydase method. Testing of the GI was conducted on 18 non-diabetic volunteers. RS content of Cr-PR coated with herbal extracts ranged between 8.27 – 8.84 % (dry weight). Cr-PR coated with all herbal extracts of 3% concentration had higher RS content than the ones with herbal extracts of 6% and 9% concentration (P <0.05). Value of the rice GI ranged 29 - 40. The lowest GI (29-30) was attained by the rice coated with enrichment of 6-9% cinnamon extract. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coating" title="coating">coating</a>, <a href="https://publications.waset.org/abstracts/search?q=Cr-fortified-parboiled%20rice" title=" Cr-fortified-parboiled rice"> Cr-fortified-parboiled rice</a>, <a href="https://publications.waset.org/abstracts/search?q=glycemic%20index" title=" glycemic index"> glycemic index</a>, <a href="https://publications.waset.org/abstracts/search?q=herbal%20extracts" title=" herbal extracts"> herbal extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=resistant%20starch" title=" resistant starch"> resistant starch</a> </p> <a href="https://publications.waset.org/abstracts/37604/evaluation-of-chromium-fortified-parboiled-rice-coated-with-herbal-extracts-resistant-starch-and-glycemic-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37604.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">357</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">37</span> Urban Conservation Methodology for Heritage Areas Case Study "Qabel Street, Old Jeddah" </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Elborombaly">Hossam Elborombaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Y.%20Azab"> Nader Y.

Traffic counting as a kind of traffic control is important to know the road traffic density in real time. This paper presents a fast and robust traffic counting system using different image processing techniques. The proposed system is composed of the following four fundamental building phases: image acquisition, pre-processing, object detection, and finally counting the connected objects. The object detection phase is comprised of the following five steps: subtracting the background, converting the image to binary, closing gaps and connecting nearby blobs, image smoothing to remove noises and very small objects, and detecting the connected objects. Experimental results show the great success of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traffic%20counting" title="traffic counting">traffic counting</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20management" title=" traffic management"> traffic management</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20detection" title=" object detection"> object detection</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a> </p> <a href="https://publications.waset.org/abstracts/43835/robust-and-real-time-traffic-counting-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43835.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Cytotoxic Activity Of Major Iridoids From Barleria Trispinosa (Forssk.)

They must allow the plant to generate a high amount of energy while inspecting and maintaining the safety of the plant. This type of occupation comes with high amounts of mental fatigue, and a small mistake can have grave consequences. Electroencephalography (EEG) is a method of gathering the electromagnetic waves emitted by a human brain. We propose a safety system by monitoring brainwaves for signs of mental fatigue. This requires an analysis of the tasks and mental models of the NPP operator, as well as risk factors on mental fatigue and attention that NPP operators face when performing their tasks. The brain waves generated from experiencing mental fatigue can then be monitored for. These factors are analyzed, developing an EEG-based monitoring system, which aims to alert NPP operators when levels of mental fatigue and attention start affecting their performance in task completion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEG" title="EEG">EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant%20operator" title=" power plant operator"> power plant operator</a>, <a href="https://publications.waset.org/abstracts/search?q=psychology" title=" psychology"> psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20analysis" title=" task analysis"> task analysis</a> </p> <a href="https://publications.waset.org/abstracts/154276/analysis-of-nuclear-power-plant-operator-activities-and-risk-factors-using-an-eeg-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154276.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">99</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">32</span> Modeling of a Small Unmanned Aerial Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Elsayed%20Ahmed">Ahmed Elsayed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Hafez"> Ashraf Hafez</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20N.%20Ouda"> A.

Technology advancements have enabled the development of it to do many excellent jobs as reconnaissance, surveillance, battle fighters, and communications relays. Simulating a small unmanned aerial vehicle (SUAV) dynamics and analyzing its behavior at the preflight stage is too important and more efficient. The first step in the UAV design is the mathematical modeling of the nonlinear equations of motion. In this paper, a survey with a standard method to obtain the full non-linear equations of motion is utilized,and then the linearization of the equations according to a steady state flight condition (trimming) is derived. This modeling technique is applied to an Ultrastick-25e fixed wing UAV to obtain the valued linear longitudinal and lateral models. At the end, the model is checked by matching between the behavior of the states of the non-linear UAV and the resulted linear model with doublet at the control surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UAV" title="UAV">UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=equations%20of%20motion" title=" equations of motion"> equations of motion</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=linearization" title=" linearization"> linearization</a> </p> <a href="https://publications.waset.org/abstracts/23317/modeling-of-a-small-unmanned-aerial-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23317.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">743</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">31</span> Rejuvenate: Face and Body Retouching Using Image Inpainting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Abdelrahman">Hossam Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sama%20Rostom"> Sama Rostom</a>, <a href="https://publications.waset.org/abstracts/search?q=Reem%20Yassein"> Reem Yassein</a>, <a href="https://publications.waset.org/abstracts/search?q=Yara%20Mohamed"> Yara Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Salah"> Salma Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour%20Awny"> Nour Awny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In today’s environment, people are becoming increasingly interested in their appearance. However, they are afraid of their unknown appearance after a plastic surgery or treatment. Accidents, burns and genetic problems such as bowing of body parts of people have a negative impact on their mental health with their appearance and this makes them feel uncomfortable and underestimated. The approach presents a revolutionary deep learning-based image inpainting method that analyses the various picture structures and corrects damaged images. In this study, A model is proposed based on the in-painting of medical images with Stable Diffusion Inpainting method. Reconstructing missing and damaged sections of an image is known as image inpainting is a key progress facilitated by deep neural networks. The system uses the input of the user of an image to indicate a problem, the system will then modify the image and output the fixed image, facilitating for the patient to see the final result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generative%20adversarial%20network" title="generative adversarial network">generative adversarial network</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20mask%20inpainting" title=" large mask inpainting"> large mask inpainting</a>, <a href="https://publications.waset.org/abstracts/search?q=stable%20diffusion%20inpainting" title=" stable diffusion inpainting"> stable diffusion inpainting</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20surgery" title=" plastic surgery"> plastic surgery</a> </p> <a href="https://publications.waset.org/abstracts/171208/rejuvenate-face-and-body-retouching-using-image-inpainting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171208.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">74</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">30</span> Analysis of Human Mental and Behavioral Models for Development of an Electroencephalography-Based Human Performance Management System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Gaber">John Gaber</a>, <a href="https://publications.waset.org/abstracts/search?q=Youssef%20Ahmed"> Youssef Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossam%20A.%20Gabbar"> Hossam A.

During abnormal situations, the likelihood of human error is many-fold higher due to the higher cognitive workload. The most common cause of human error and high cognitive workload is mental fatigue. Electroencephalography (EEG) is a method of gathering the electromagnetic waves emitted by a human brain. We propose a safety system by monitoring brainwaves for signs of mental fatigue using an EEG system. This requires an analysis of the mental model of the NPP operator, changes in brain wave power in response to certain stimuli, and the risk factors on mental fatigue and attention that NPP operators face when performing their tasks. We analyzed these factors and developed an EEG-based monitoring system, which aims to alert NPP operators when levels of mental fatigue and attention hinders their ability to maintain safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20imaging" title="brain imaging">brain imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant%20operator" title=" power plant operator"> power plant operator</a>, <a href="https://publications.waset.org/abstracts/search?q=psychology" title=" psychology"> psychology</a> </p> <a href="https://publications.waset.org/abstracts/153245/analysis-of-human-mental-and-behavioral-models-for-development-of-an-electroencephalography-based-human-performance-management-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153245.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">102</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">29</span> Cytotoxic Metabolites from Tagetes minuta L.

In our implementations, the experimental-based ‘nonlinear’ dopant drift model is adopted along with the proposed circuits providing incorporation of all known non-idealities of practically realized memristor and gaining high operation frequency. The suggested designs leverage the distinctive characteristics of the memristor device, definitely, its changeable average memristance versus the frequency, phase and amplitude of the periodic excitation input. The proposed demodulators feature small integration area, low power consumption, and easy implementation. Moreover, the proposed QAM demodulator precludes the requirement for the carrier recovery circuits. In doing so, the designs were validated by transient simulations using the nonlinear dopant drift memristor model. The simulations results show high agreement with the theory presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BFSK" title="BFSK">BFSK</a>, <a href="https://publications.waset.org/abstracts/search?q=demodulator" title=" demodulator"> demodulator</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20frequency%20memristor%20applications" title=" high frequency memristor applications"> high frequency memristor applications</a>, <a href="https://publications.waset.org/abstracts/search?q=memristor%20based%20analog%20circuits" title=" memristor based analog circuits"> memristor based analog circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20dopant%20drift%20model" title=" nonlinear dopant drift model"> nonlinear dopant drift model</a>, <a href="https://publications.waset.org/abstracts/search?q=QAM" title=" QAM"> QAM</a> </p> <a href="https://publications.waset.org/abstracts/125099/high-frequency-memristor-based-bfsk-and-8qam-demodulators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125099.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">167</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">27</span> Phytochemical and Biological Study of Chrozophora oblongifolia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Braa%20Kashegari">Al-Braa Kashegari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20M.%20El-Halawany"> Ali M.

The isolated compounds were tested for their antioxidant activity using different assays viz., DPPH, FRAP, ABTS, ORAC, and metal chelation effects. In addition, the inhibition of target enzymes involved in the metabolic syndrome, such as alpha-glucosidase and pancreatic lipase, were carried out. Moreover, the effect of the compounds on the advanced glycation end-products (AGEs) as one of the major complications of oxidative stress and hyperglycemia in metabolic syndromes were carried out using BSA‐fructose (bovine serum albumin), BSA-methylglyoxal, and arginine methylglyoxal models. The pure isolates showed a protective effect in metabolic syndromes as well as promising antioxidant activity. The results showed potent activity of compound 5 in all measured parameters meanwhile, none of the tested compounds showed activity against pancreatic lipase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chrozophora%20oblongifolia" title="Chrozophora oblongifolia">Chrozophora oblongifolia</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=pancreatic%20lipase" title=" pancreatic lipase"> pancreatic lipase</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndromes" title=" metabolic syndromes"> metabolic syndromes</a> </p> <a href="https://publications.waset.org/abstracts/136821/phytochemical-and-biological-study-of-chrozophora-oblongifolia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136821.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">111</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">26</span> A phytochemical and Biological Study of Viscum schemperi Engl.

Anti-inflammatory and anti-apoptotic activities of oleanolic acid in a mouse model of acute hepatorenal damage were assessed. This study showed the efficacy of oleanolic acid to counteract thioacetamide-induced hepatic and kidney injury in mice through the reduction of hepatocyte oxidative damage, suppression of inflammation, and apoptosis. More importantly, oleanolic acid suppressed thioacetamide-induced hepatic and kidney injury by inhibiting NF-κB/TNF-α-mediated inflammation/apoptosis and enhancing SIRT1/Nrf2/Heme-oxygenase signalling pathway. These promising pharmacological activities suggest the potential use of oleanolic acid against hepatorenal damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oleanolic%20acid" title="oleanolic acid">oleanolic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=viscum%20schimperi" title=" viscum schimperi"> viscum schimperi</a>, <a href="https://publications.waset.org/abstracts/search?q=thioacetamide" title=" thioacetamide"> thioacetamide</a>, <a href="https://publications.waset.org/abstracts/search?q=SIRT1%2FNrf2%2FNF-%CE%BAB" title=" SIRT1/Nrf2/NF-κB"> SIRT1/Nrf2/NF-κB</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatorenal%20damage" title=" hepatorenal damage"> hepatorenal damage</a> </p> <a href="https://publications.waset.org/abstracts/169183/a-phytochemical-and-biological-study-of-viscum-schemperi-engl-growing-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169183.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">98</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">25</span> Geotechnical Investigation of Soil Foundation for Ramps of Dawar El-Tawheed Bridge in Jizan City, Kingdom of Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20H.%20Mahfouz">Ali H.

The clay layer induces high settlement due to surcharge application of earth embankment at ramp T1, ramp T2, and ramp T3 especially at heights from 9m right 3m. Calculated settlement for embankment heights less than 3m may be accepted regarding Saudi Code for soil and foundation. The soil and groundwater at the project site comprise high contents of sulfates and chlorides of high aggressively on concrete and steel bars, respectively. Regarding results of the study, it has been recommended to use stone column piles or new technology named PCC piles as soil improvement to improve the bearing capacity of the weak layer. The new technology is cast in-situ thin wall concrete pipe piles (PCC piles), it has economically advantageous and high workability. The technology can save time of implementation and cost of application is almost 30% of other types of piles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20foundation%20soil" title="soft foundation soil">soft foundation soil</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing%20capacity" title=" bearing capacity"> bearing capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=bridge%20ramps" title=" bridge ramps"> bridge ramps</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20improvement" title=" soil improvement"> soil improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=geogrid" title=" geogrid"> geogrid</a>, <a href="https://publications.waset.org/abstracts/search?q=PCC%20piles" title=" PCC piles"> PCC piles</a> </p> <a href="https://publications.waset.org/abstracts/43863/geotechnical-investigation-of-soil-foundation-for-ramps-of-dawar-el-tawheed-bridge-in-jizan-city-kingdom-of-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43863.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">399</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">24</span> Effect of Bored Pile Diameter in Sand on Friction Resistance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Mohammed%20M.%20Eid">Ashraf Mohammed M.

These factors can be represented analytically to study the influence of diameter on the unit skin friction. In this research, the Egyptian Code of soil mechanics is used to assess the skin friction capacity for either the ordinary pile diameter as well as for the large pile diameter. The later is presented in the code and through the work of some researchers based on the results of investigations adopted for a sufficient number of field tests. The comparative results of these researchers with respect to the Egyptian Code are used to check the adequacy of both methods. Based on the results of this study, the traditional static formula adopted for piles of diameter less than 60 cm may be continually used for larger piles by correlating the analyzed formulae. Accordingly, the corresponding modified angle of internal friction is concluded demonstrating a reduction of shear strength due to soil disturbance along the pile shaft. Based on this research the difference between driven piles and bored piles constructed in same soil can be assessed and a better understanding can be evaluated for the effect of different factors on pile skin friction capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=large%20piles" title="large piles">large piles</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20formula" title=" static formula"> static formula</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20piles" title=" friction piles"> friction piles</a>, <a href="https://publications.waset.org/abstracts/search?q=sandy%20soils" title=" sandy soils"> sandy soils</a> </p> <a href="https://publications.waset.org/abstracts/27820/effect-of-bored-pile-diameter-in-sand-on-friction-resistance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27820.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">500</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">23</span> Canada Deuterium Uranium Updated Fire Probabilistic Risk Assessment Model for Canadian Nuclear Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Shalabi">Hossam Shalabi</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Hadjisophocleous"> George Hadjisophocleous</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Canadian Nuclear Power Plants (NPPs) use some portions of NUREG/CR-6850 in carrying out Fire Probabilistic Risk Assessment (PRA). An assessment for the applicability of NUREG/CR-6850 to CANDU reactors was performed and a CANDU Fire PRA was introduced. There are 19 operating CANDU reactors in Canada at five sites (Bruce A, Bruce B, Darlington, Pickering and Point Lepreau). A fire load density survey was done for all Fire Safe Shutdown Analysis (FSSA) fire zones in all CANDU sites in Canada. National Fire Protection Association (NFPA) Standard 557 proposes that a fire load survey must be conducted by either the weighing method or the inventory method or a combination of both. The combination method results in the most accurate values for fire loads. An updated CANDU Fire PRA model is demonstrated in this paper that includes the fuel survey in all Canadian CANDU stations. A qualitative screening step for the CANDU fire PRA is illustrated in this paper to include any fire events that can damage any part of the emergency power supply in addition to FSSA cables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20safety" title="fire safety">fire safety</a>, <a href="https://publications.waset.org/abstracts/search?q=CANDU" title=" CANDU"> CANDU</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear" title=" nuclear"> nuclear</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20densities" title=" fuel densities"> fuel densities</a>, <a href="https://publications.waset.org/abstracts/search?q=FDS" title=" FDS"> FDS</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20analysis" title=" qualitative analysis"> qualitative analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20probabilistic%20risk%20assessment" title=" fire probabilistic risk assessment"> fire probabilistic risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/106512/canada-deuterium-uranium-updated-fire-probabilistic-risk-assessment-model-for-canadian-nuclear-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106512.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">136</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">22</span> Development of a Novel Score for Early Detection of Hepatocellular Carcinoma in Patients with Hepatitis C Virus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatem%20A.%20El-Mezayen">Hatem A.

However, the world is dangerously facing the serious problem for the deficiency of the sources of drinking water. Within the aquatic systems, there are various gases, microbes, and other toxic ingredients (chemical compounds and heavy metals) occurred owing to the draining of agricultural and industrial wastewater, resulting in water pollution. On the other hand, fuel (gaseous, liquid, or in solid phase) is one of the extensively consumable energy sources, and owing to its origin from fossil, it contains some sulfur-, nitrogen- and oxygen-based compounds that cause serious problems (toxicity, catalyst poisoning, corrosion, and gum formation andcarcinogenic effects), to be ascribed as undesirable pollutants.MOFs as porous coordinating polymers are superiorly exploited in the adsorption and separationof contaminants for wastewater treatment and fuel purification. The inclusion of highly adsorbent materials like MOFs to be immobilized within cellulosic materialscould be investigated as a new challenge for the separation of contaminants with high efficiency and opportunity for recyclability. Therefore, the current approach ascribes the exploitation of different MOFsimmobilized within cellulose (powder, films, and fabrics)for applications in environmental.

Soldiers are like a high-performance athletes, where monitoring their physical and physiological capabilities is a vital requirement. Functional clothes represent a “second skin” that has a close, “intimate” relationship with the human body. For the application of textiles in military purposes, which is normally required in difficult weather and environmental conditions, several functions are required. The requirements for designing functional military textiles for soldier's protection can be categorized into three categories; i) battle field (protection from chemical warfare agents, flames, and thermal radiation), ii) environmental (water proof, air permeable, UV-protection, antibacterial), iii) physiological (minimize heat stress, low weight, insulative, durability). All of these requirements are important, but the means to fulfill these requirements are not simple and straight forward. Additionally, the combination of more than one function is reported to be very expensive and requires many complicated steps, and the final product is found to be low durability. Not only do all of these requirements are overlapping, but they are also contradicting each other at various levels. Thus, we plan to produce multi-functional textiles (e.g., anti-microbial, UV-protection, fire retardant, photoluminescent) to be applied in military clothes. The current project aims to use quite a simple and applicable technique through the modification of textiles with different coordination polymers and functionalized coordination polymers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20textiles" title="functional textiles">functional textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=military%20clothes" title=" military clothes"> military clothes</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination%20polymers" title=" coordination polymers"> coordination polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20retardant" title=" fire retardant"> fire retardant</a>, <a href="https://publications.waset.org/abstracts/search?q=photolumenscent" title=" photolumenscent"> photolumenscent</a> </p> <a href="https://publications.waset.org/abstracts/154826/advanced-textiles-for-soldier-clothes-based-on-coordination-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154826.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">18</span> Outdoor Performances of Micro Scale Wind Turbine Stand Alone System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed.%20A.%20Hossam%20Eldin">Ahmed.

Moreover, increased prices of fossil fuel and advanced energy conversion technology lead to the need for renewable energy resources. A study, modelling and simulation of an outdoor micro scale stand alone wind turbine was carried out. For model validation an experimental study was applied. In this research the aim was to clarify effects of real outdoor operating conditions and the instantaneous fluctuations of both wind direction and wind speed on the actual produced power. The results were compared with manufacturer’s data. The experiments were carried out in Borg Al-Arab, Alexandria. This location is on the north Western Coast of Alexandria. The results showed a real max output power for outdoor micro scale wind turbine, which is different from manufacturer’s value. This is due to the fact that the direction of wind speed is not the same as that of the manufacturer’s data. The measured wind speed and direction by the portable metrological weather station anemometer varied with time. The blade tail response could not change the blade direction at the same instant of the wind direction variation. Therefore, designers and users of micro scale wind turbine stand alone system cannot rely on the maker’s name plate data to reach the required power. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=micro-turbine" title="micro-turbine">micro-turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title=" wind turbine"> wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=inverters" title=" inverters"> inverters</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20system" title=" hybrid system"> hybrid system</a> </p> <a href="https://publications.waset.org/abstracts/32896/outdoor-performances-of-micro-scale-wind-turbine-stand-alone-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32896.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">482</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">17</span> Effect of Papaverine on Neurospheres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20Shehab-Eldeen">Noura Shehab-Eldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elsherbeeny"> Mohamed Elsherbeeny</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Elmetwally"> Hossam Elmetwally</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salama"> Mohamed Salama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Lotfy"> Ahmed Lotfy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elgamal"> Mohamed Elgamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Sheashaa"> Hussein Sheashaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sobh"> Mohamed Sobh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mitochondrial toxins including papaverine may be implicated in the etiology and pathogenesis of Parkinson's disease. The aim was to detect the effect of papaverine on the proliferation and viability of neural stem cells. Rat neural progenitor cells were isolated from embryos (E14) brains. The dispersed tissues were allowed to settle, then, The supernatant was centrifuged at 1,000 g for 5 min. The pellet was placed in Hank’s solution cultured as free-floating neurospheres Dulbecco’s modified Eagle medium (DMEM) and Hams F12 (3:1) supplemented with B27 (Invitrogen GmBH, Karlsruhe, Germany), 20 ng/mL epidermal growth factor (EGF; Biosource, Karlsruhe, Germany), 20 ng/mL recombinant human fibroblast growth factor (rhFGF; R&D Systems, Wiesbaden-Nordenstadt, Germany), and penicillin and streptomycin (1:100; Invitrogen) at 37°C with 7.5% CO2 . Differentiation was initiated by growth factor withdrawal and plating onto a poly-d-lysine/ laminin matrix. The neurospheres were fed every 2-3 days by replacing 50% of the culture media with fresh media. The culture suspension was transferred to a dish containing 16 wells. The wells were divided as follows: 4 wells received no papaverine (control), 4 wells 1 u, 4 wells 5 u and 4 wells 10 u of papaverine solution. In the next 2 weeks, photography (0,4,5,11days) and viability test were done. The photographs were analysed. Results : papaverine didn't affect proliferation of neurospheres, while it affected viability compared to control , this was dose related. Conclusion: This indicates the harmful effect of papaverine suggesting it to be a candidate neurotoxin causing Parkinsonism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurospheres" title="neurospheres">neurospheres</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20stem%20cells" title=" neural stem cells"> neural stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=papaverine" title=" papaverine"> papaverine</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinsonism" title=" Parkinsonism"> Parkinsonism</a> </p> <a href="https://publications.waset.org/abstracts/14864/effect-of-papaverine-on-neurospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14864.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">660</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">16</span> Methods Employed to Mitigate Wind Damage on Ancient Egyptian Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Mohamed%20Abdelfattah%20Helal%20Hegazi">Hossam Mohamed Abdelfattah Helal Hegazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Winds and storms are considered crucial weathering factors, representing primary causes of destruction and erosion for all materials on the Earth's surface. This naturally includes historical structures, with the impact of winds and storms intensifying their deterioration, particularly when carrying high-hardness sand particles during their passage across the ground. Ancient Egyptians utilized various methods to prevent wind damage to their ancient architecture throughout the ancient Egyptian periods . One of the techniques employed by ancient Egyptians was the use of clay or compacted earth as a filling material between opposing walls made of stone, bricks, or mud bricks. The walls made of reeds or woven tree branches were covered with clay to prevent the infiltration of winds and rain, enhancing structural integrity, this method was commonly used in hollow layers . Additionally, Egyptian engineers innovated a type of adobe brick with uniformly leveled sides, manufactured from dried clay. They utilized stone barriers, constructed wind traps, and planted trees in rows parallel to the prevailing wind direction. Moreover, they employed receptacles to drain rainwater resulting from wind-loaded rain and used mortar to fill gaps in roofs and structures. Furthermore, proactive measures such as the removal of sand from around historical and archaeological buildings were taken to prevent adverse effects <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=winds" title="winds">winds</a>, <a href="https://publications.waset.org/abstracts/search?q=storms" title=" storms"> storms</a>, <a href="https://publications.waset.org/abstracts/search?q=weathering" title=" weathering"> weathering</a>, <a href="https://publications.waset.org/abstracts/search?q=destruction" title=" destruction"> destruction</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=materials" title=" materials"> materials</a>, <a href="https://publications.waset.org/abstracts/search?q=Earth%27s%20surface" title=" Earth's surface"> Earth's surface</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20structures" title=" historical structures"> historical structures</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a> </p> <a href="https://publications.waset.org/abstracts/184858/methods-employed-to-mitigate-wind-damage-on-ancient-egyptian-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184858.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">62</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">15</span> Global Culture Museums: Bridging Societies, Fostering Understanding, and Preserving Heritage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Hegazi">Hossam Hegazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global culture museums play a pivotal role in fostering cross-cultural connections, enhancing mutual understanding, and safeguarding the rich tapestry of cultural heritage. These institutions serve as dynamic bridges, facilitating the exchange of ideas and values among diverse societies. One of the primary functions of global culture museums is to connect people from different backgrounds. By showcasing the artistic expressions, traditions, and historical artifacts of various civilizations, these museums create a shared space for dialogue. Visitors are afforded the opportunity to explore and appreciate the nuances of cultures different from their own, promoting a sense of global interconnectedness. Moreover, these museums contribute significantly to mutual understanding. Through interactive exhibits, innovative technologies, and educational programs, they offer immersive experiences that transcend linguistic and geographical barriers. Visitors gain insights into the customs, beliefs, and lifestyles of others, fostering empathy and appreciation for cultural diversity. Preserving cultural heritage stands as another key objective of global culture museums. By housing and curating artifacts, artworks, and historical items, these institutions play a crucial role in safeguarding the collective memory of humanity. This preservation effort ensures that future generations have access to the cultural legacies that have shaped societies across the globe. In conclusion, global culture museums serve as dynamic hubs that bring people together, promote understanding, and safeguard the wealth of human cultural heritage. Their impact extends beyond the walls of exhibition halls, contributing to a more interconnected and culturally enriched world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20culture%20museums" title="global culture museums">global culture museums</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-cultural%20connections" title=" cross-cultural connections"> cross-cultural connections</a>, <a href="https://publications.waset.org/abstracts/search?q=mutual%20understanding" title=" mutual understanding"> mutual understanding</a>, <a href="https://publications.waset.org/abstracts/search?q=societal%20dialogue" title=" societal dialogue"> societal dialogue</a> </p> <a href="https://publications.waset.org/abstracts/187472/global-culture-museums-bridging-societies-fostering-understanding-and-preserving-heritage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187472.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">29</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">14</span> Acute Neurophysiological Responses to Resistance Training; Evidence of a Shortened Super Compensation Cycle and Early Neural Adaptations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Latella">Christopher Latella</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashlee%20M.%20Hendy"> Ashlee M.

Understanding neural responses from an acute resistance training session is pivotal in the prescription of frequency, intensity and volume in applied strength and conditioning practice. Therefore the primary aim of this study was to investigate the time course of neurophysiological mechanisms post training against current super compensation theory, and secondly, to examine whether these responses reflect neural adaptations observed with resistance training interventions. Methods: Participants (N=14) completed a randomised, counterbalanced crossover study comparing; control, strength and hypertrophy conditions. The strength condition involved 3 x 5RM leg extensions with 3min recovery, while the hypertrophy condition involved 3 x 12 RM with 60s recovery. Transcranial magnetic stimulation (TMS) and peripheral nerve stimulation were used to measure excitability of the central and peripheral neural pathways, and maximal voluntary contraction (MVC) to quantify strength changes. Measures were taken pre, immediately post, 10, 20 and 30 mins and 1, 2, 6, 24, 48, 72 and 96 hrs following training. Results: Significant decreases were observed at post, 10, 20, 30 min, 1 and 2 hrs for both training groups compared to control group for force, (p <.05), maximal compound wave; (p < .005), silent period; (p < .05). A significant increase in corticospinal excitability; (p < .005) was observed for both groups. Corticospinal excitability between strength and hypertrophy groups was near significance, with a large effect (η2= .202). All measures returned to baseline within 6 hrs post training. Discussion: Neurophysiological mechanisms appear to be significantly altered in the period 2 hrs post training, returning to homeostasis by 6 hrs. The evidence suggests that the time course of neural recovery post resistance training occurs 18-40 hours shorter than previous super compensation models. Strength and hypertrophy protocols showed similar response profiles with current findings suggesting greater post training corticospinal drive from hypertrophy training, despite previous evidence that strength training requires greater neural input. The increase in corticospinal drive and decrease inl inhibition appear to be a compensatory mechanism for decreases in peripheral nerve excitability and maximal voluntary force output. The changes in corticospinal excitability and inhibition are akin to adaptive processes observed with training interventions of 4 wks or longer. It appears that the 2 hr recovery period post training is the most influential for priming further neural adaptations with resistance training. Secondly, the frequency of prescribed resistance sessions can be scheduled closer than previous super compensation theory for optimal strength gains. <p class="card-text"><strong>Keywords:</strong> <a
