Vibrancy provides a livable, attractive and secure environments; it also boosts the city’s economy and social life. Vibrant city is a city full of energy and life. To achieve this, a number of resources are needed; namely specific urban density, the availability of alternative modes of transportation and finally diversity of land-uses. Literature review shows no comprehensive study that assesses vibrancy in the streets of modern Alexandria. This study aims to measure the vibrancy potential in Sidi-Gaber station area thought the assessment of existing resources performance. Methods include literature reviews, surveying of existing case, questionnaire as well as GIS techniques. Expected results include GIS maps defining the vibrancy potentials in land use, density and statistical study regarding public transportation use in the area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandria" title="Alexandria">Alexandria</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20use" title=" mixed use"> mixed use</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation" title=" transportation"> transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrancy" title=" vibrancy"> vibrancy</a> </p> <a href="https://publications.waset.org/abstracts/52822/vibrancy-in-the-city-the-problem-of-sidi-gaber-station-zone-in-alexandria-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52822.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">293</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">109</span> Antioxidants Reveal Protection against the Biochemical Changes in Liver, Kidney, and Blood Profiles after Clindamycin/Ibuprofen Administration in Dental Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gouda%20K.%20Helal">Gouda K.

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">97</span> High Frequency Sonochemistry: A New Field of Cavitation‐Free Acoustic Materials Synthesis and Manipulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amgad%20Rezk">Amgad Rezk</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20Ahmed"> Heba Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Leslie%20Yeo"> Leslie Yeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ultrasound presents a powerful means for material synthesis. In this talk, we showcase a new field demonstrating the possibility for harnessing sound energy sources at considerably higher frequencies (10 MHz to 1 GHz) compared to conventional ultrasound (kHz and up to ~2 MHz) for crystalising and manipulating a variety of nanoscale materials. At these frequencies, cavitation—which underpins most sonochemical processes—is largely absent, suggesting that altogether fundamentally different mechanisms are at dominant. Examples include the crystallization of highly oriented structures, quasi-2D metal-organic frameworks and nanocomposites. These fascinating examples reveal how the highly nonlinear electromechanical coupling associated with high-frequency surface vibration gives rise to molecular ordering and assembly on the nano and microscale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-frequency%20acoustics" title="high-frequency acoustics">high-frequency acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallisation" title=" crystallisation"> crystallisation</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20nanomaterials" title=" composite nanomaterials"> composite nanomaterials</a> </p> <a href="https://publications.waset.org/abstracts/147372/high-frequency-sonochemistry-a-new-field-of-cavitationfree-acoustic-materials-synthesis-and-manipulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147372.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">121</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">96</span> Reducing Inventory Costs by Reducing Inventory Levels: Kuwait Flour Mills and Bakeries Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dana%20Al-Qattan">Dana Al-Qattan</a>, <a href="https://publications.waset.org/abstracts/search?q=Faiza%20Goodarzi"> Faiza Goodarzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20Al-Resheedan"> Heba Al-Resheedan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kawther%20Shehab"> Kawther Shehab</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoug%20Al-Ansari"> Shoug Al-Ansari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This project involves working with different types of forecasting methods and facility planning tools to help the company we have chosen to improve and reduce its inventory, increase its sales, and decrease its wastes and losses.

The catalysts were prepared by physical mixing, precipitation, and ultrasonication methods and labeled as catalysts A-C. The structural and texture properties of the obtained catalysts were confirmed by X-ray diffraction (XRD), BET-surface area analysis and transmission electron microscopy (TEM). The photocatalytic activity of the three catalysts towards hydrogen generation was then tested. Promising hydrogen productivity was obtained by the three catalysts however different gases compositions were obtained by each type of catalyst. Specifically, catalyst A had produced hydrogen mixed with CO₂ while the composite structure (catalyst B) had generated only pure H₂. In the case of catalyst C, syngas made of H₂ and CO was revealed, as a novel product, for the first time, in such process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20production" title="hydrogen production">hydrogen production</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20splitting" title=" water splitting"> water splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysts" title=" photocatalysts"> photocatalysts</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20energy" title=" clean energy "> clean energy </a> </p> <a href="https://publications.waset.org/abstracts/82416/photocatalytic-conversion-of-watermethanol-mixture-into-hydrogen-using-ceriumiron-oxides-based-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82416.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">240</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">94</span> Enhanced Bit Error Rate in Visible Light Communication: A New LED Hexagonal Array Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Matter">Karim Matter</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20Fayed"> Heba Fayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abd-Elaziz"> Ahmed Abd-Elaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Moustafa%20Hussein"> Moustafa Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the exponential growth of mobile devices and wireless services, a huge demand for radiofrequency has increased. The presence of several frequencies causes interference between cells, which must be minimized to get the lower Bit Error Rate (BER). For this reason, it is of great interest to use visible light communication (VLC). This paper suggests a VLC system that decreases the BER by applying a new LED distribution with a hexagonal shape using a Frequency Reuse (FR) concept to mitigate the interference between the reused frequencies inside the hexagonal shape. The BER is measured in two scenarios, Line of Sight (LoS) and Non-Line of Sight (Non-LoS), for each technique that we used. The recommended values of BER in the proposed model for Soft Frequency Reuse (SFR) in the case of Los at 4, 8, and 10 dB signal to noise ratio (SNR), are 3.6×10⁻⁶, 6.03×10⁻¹³, and 2.66×10⁻¹⁸, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visible%20light%20communication%20%28VLC%29" title="visible light communication (VLC)">visible light communication (VLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20of%20view%20%28FoV%29" title=" field of view (FoV)"> field of view (FoV)</a>, <a href="https://publications.waset.org/abstracts/search?q=hexagonal%20array" title=" hexagonal array"> hexagonal array</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20reuse" title=" frequency reuse"> frequency reuse</a> </p> <a href="https://publications.waset.org/abstracts/146526/enhanced-bit-error-rate-in-visible-light-communication-a-new-led-hexagonal-array-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146526.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">160</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">93</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">92</span> Strategic Citizen Participation in Applied Planning Investigations: How Planners Use Etic and Emic Community Input Perspectives to Fill-in the Gaps in Their Analysis</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> </p> <p class="card-text"><strong>Abstract:</strong></p> Planners regularly use citizen input as empirical data to help them better understand community issues they know very little about. This type of community data is based on the lived experiences of local residents and is known as "emic" data. What is becoming more common practice for planners is their use of data from local experts and stakeholders (known as "etic" data or the outsider perspective) to help them fill in the gaps in their analysis of applied planning research projects. Utilizing international Health Impact Assessment (HIA) data, I look at who planners invite to their citizen input investigations. Research presented in this paper shows that planners access a wide range of emic and etic community perspectives in their search for the “community’s view.” The paper concludes with how planners can chart out a new empirical path in their execution of emic/etic citizen participation strategies in their applied planning research projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citizen%20participation" title="citizen participation">citizen participation</a>, <a href="https://publications.waset.org/abstracts/search?q=emic%20data" title=" emic data"> emic data</a>, <a href="https://publications.waset.org/abstracts/search?q=etic%20data" title=" etic data"> etic data</a>, <a href="https://publications.waset.org/abstracts/search?q=Health%20Impact%20Assessment%20%28HIA%29" title=" Health Impact Assessment (HIA)"> Health Impact Assessment (HIA)</a> </p> <a href="https://publications.waset.org/abstracts/15997/strategic-citizen-participation-in-applied-planning-investigations-how-planners-use-etic-and-emic-community-input-perspectives-to-fill-in-the-gaps-in-their-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15997.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">484</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">91</span> Developing EFL Research Skills of Pre-Master Students through a Suggested Quest Based Learning Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heba%20Mustafa%20Abdullah">Heba Mustafa Abdullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research aimed at examining the effect of a using a quest based learning strategy on developing EFL Pre-Master Students.

The pharmacological distinction between synthetic and naturally occurring steroids centers on changes in biological activity dependent on compound formulation and an individual's metabolism. OC mechanism of action is explained as the main prevention of ovulation by interference with gonadotropin-releasing hormone. Since some 52 metabolic alterations have been reported in OC users, these phenomena are dealt with in 3 categories: 1) effects on the primary target organs of the female reproductive tract (ovary, myometrium, endometrium, cervix, vagina, breasts, and hypothalamus), 2) general metabolic effects (serum proteins, carbohydrate metabolism, lipid metabolism, water and electrolyte metabolism, body weight, tryptophan metabolism, and vitamins and minerals), and 3) effects on other organ systems (liver, central nervous system, skin, genitourinary, gastrointestinal tract, eye, immune phenomena, and effect on subsequent fertility). The choice of the proper OC formulation and use of OCs by adolescents are discussed. Assessment of OC safety, contraindications, and patient monitoring are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steroid%20oral%20contraceptives" title="steroid oral contraceptives">steroid oral contraceptives</a>, <a href="https://publications.waset.org/abstracts/search?q=ovulation" title=" ovulation"> ovulation</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20reproductive%20tract" title=" female reproductive tract"> female reproductive tract</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20effects" title=" metabolic effects"> metabolic effects</a> </p> <a href="https://publications.waset.org/abstracts/160813/the-pharmacology-and-physiology-of-steroid-oral-contraceptives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160813.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">96</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">89</span> The Efficiency of Cytochrome Oxidase Subunit 1 Gene (cox1) in Reconstruction of Phylogenetic Relations among Some Crustacean Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20M.%20Saad">Yasser M.

Prickly Pear Peel (Opuntia ficus-indica) has been used as a carbon source for production of rhamnolipid. Finally, the optimum conditions for rhamnolipid production were applied in 5L working volume bioreactors at different aerations, agitation and controlled pH for maximum rhamnolipid production. In addition, kinetic studies of rhamnolipids production have been reported. At the end of the batch bioreactor optimization process, rhamnolipids production by P. aeruginosa PAO1 has reached the worldwide levels and can be applied for its industrial production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhamnolipids" title="rhamnolipids">rhamnolipids</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomonas%20aeruginosa" title=" pseudomonas aeruginosa"> pseudomonas aeruginosa</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20optimization" title=" statistical optimization"> statistical optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=tagushi" title=" tagushi"> tagushi</a>, <a href="https://publications.waset.org/abstracts/search?q=opuntia%20ficus-indica" title=" opuntia ficus-indica"> opuntia ficus-indica</a> </p> <a href="https://publications.waset.org/abstracts/88618/statistical-optimization-and-production-of-rhamnolipid-by-p-aeruginosa-pao1-using-prickly-pear-peel-as-a-carbon-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88618.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">86</span> Study the Effect of Dermal Application of Stone Hair Dye on Experimental Animals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Abdel%20Moniem%20Ahmed">Hatem Abdel Moniem Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ragaa%20Mohamed%20Abdel%20Maaboud"> Ragaa Mohamed Abdel Maaboud</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20A.%20Mubarak"> Heba A.
