AFM images show a dense surface of columnar grains with a roughness of 78.69 nm. The PL measurements at 7 K reveal the presence of PL peaks centered in IR and visible regions. They are attributed to radiative transitions via oxygen vacancies, Sn interstitials, and dangling bonds. A bands diagram model is presented with the approximate positions of intrinsic point defect levels in SnO₂ thin films. The integrated PL measurements demonstrate the good thermal stability of our sample, which makes it very useful in optoelectronic devices functioning at room temperature. The unusual behavior of the evolution of PL peaks and their full width at half maximum as a function of temperature indicates the thermal sensitivity of the point defects present in the band gap. The shallower energy levels due to dangling bonds and/or oxygen vacancies are more sensitive to the temperature. However, volume defects like Sn interstitials are thermally stable and constitute deep and stable energy levels for excited electrons. Small redshifting of PL peaks is observed with increasing temperature. This behavior is attributed to the reduction of oxygen vacancies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transparent%20conducting%20oxide" title="transparent conducting oxide">transparent conducting oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=intrinsic%20point%20defects" title=" intrinsic point defects"> intrinsic point defects</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductors" title=" semiconductors"> semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen%20vacancies" title=" oxygen vacancies"> oxygen vacancies</a> </p> <a href="https://publications.waset.org/abstracts/161707/effect-of-intrinsic-point-defects-on-the-structural-and-optical-properties-of-sno2-thin-films-grown-by-ultrasonic-spray-pyrolysis-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161707.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">85</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">196</span> The Future Shrouded by the Ghost of History: Palestinian Science Fiction "The Key"</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=KongQue">KongQue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Palestinian novelist Anwar Hamed’s work "The Key" is a science fiction that profoundly metaphors the Palestinian issue. In the novel, Anwar Hamed uses the "key", a popular symbol of Palestinian resistance culture, to symbolize the history of "Nakba" and the Palestinians' right to return, and uses the ghost lingering outside the door of the Israelis as a metaphor Palestinians and the Palestinian issue, for being covered, hidden, and turned a blind eye. Through the literary genre of science fiction, Anwar Hamed continues the literary tradition of Palestinian writers recreating the historical trauma of the Palestinians, explores the causes of the inability to communicate between Palestine and Israel, and attempts to reawaken concern over the plight of Palestinian refugees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palestine" title="palestine">palestine</a>, <a href="https://publications.waset.org/abstracts/search?q=key" title=" key"> key</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20fiction" title=" science fiction"> science fiction</a>, <a href="https://publications.waset.org/abstracts/search?q=arabic%20literature" title=" arabic literature"> arabic literature</a> </p> <a href="https://publications.waset.org/abstracts/175597/the-future-shrouded-by-the-ghost-of-history-palestinian-science-fiction-the-key" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175597.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">71</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">195</span> Use of Improved Genetic Algorithm in Cloud Computing to Reduce Energy Consumption in Migration of Virtual Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marziyeh%20Bahrami">Marziyeh Bahrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Pahlevan%20Hsseini"> Hamed Pahlevan Hsseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnam%20Ghamami"> Behnam Ghamami</a>, <a href="https://publications.waset.org/abstracts/search?q=Arman%20Alvanpour"> Arman Alvanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Ezzati"> Hamed Ezzati</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Salar%20Sadeghi"> Amir Salar Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the ways to increase the efficiency of services in the system of agents and, of course, in the world of cloud computing, is to use virtualization techniques. The aim of this research is to create changes in cloud computing services that will reduce as much as possible the energy consumption related to the migration of virtual machines and, in some way, the energy related to the allocation of resources and reduce the amount of pollution. So far, several methods have been proposed to increase the efficiency of cloud computing services in order to save energy in the cloud environment. The method presented in this article tries to prevent energy consumption by data centers and the subsequent production of carbon and biological pollutants as much as possible by increasing the efficiency of cloud computing services. The results show that the proposed algorithm, using the improvement in virtualization techniques and with the help of a genetic algorithm, improves the efficiency of cloud services in the matter of migrating virtual machines and finally saves consumption. becomes energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumption%20reduction" title="consumption reduction">consumption reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=live%20migration" title=" live migration"> live migration</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20Machine" title=" virtual Machine"> virtual Machine</a> </p> <a href="https://publications.waset.org/abstracts/185270/use-of-improved-genetic-algorithm-in-cloud-computing-to-reduce-energy-consumption-in-migration-of-virtual-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185270.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">60</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">194</span> Isolation and Identification of Diacylglycerol Acyltransferase Type-2 (GAT2) Genes from Three Egyptian Olive Cultivars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yahia%20I.%20Mohamed">Yahia I.

Methods of evaluation are the measurement of the WHO oral mucositis scale and the common toxicity criteria scale. Methods: Thirty cancer patients receiving chemotherapy (males and females) who had oral mucositis and ulceration pain, and their ages ranged from 30 to 55 years, were divided into two groups. Group (A), composed of 15 patients, received the Bioptron light therapy (BLT) in addition to the routine medical care of oral mucositis. Group (B) received only the routine medical care of oral mucositis; the duration of the BLT application was 10 minutes applied daily for 30 days. Results and conclusion: Results showed that the application of the BLT had valuable healing effects on oral mucositis in cancer patients receiving chemotherapy, as evidenced by the high decreases of the WHO oral mucositis scale and the common toxicity criteria scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bioptron%20light%20therapy" title="Bioptron light therapy">Bioptron light therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20mucositis" title=" oral mucositis"> oral mucositis</a>, <a href="https://publications.waset.org/abstracts/search?q=WHO%20oral%20mucositis%20scale" title=" WHO oral mucositis scale"> WHO oral mucositis scale</a>, <a href="https://publications.waset.org/abstracts/search?q=common%20toxicity%20criteria%20scale" title=" common toxicity criteria scale"> common toxicity criteria scale</a> </p> <a href="https://publications.waset.org/abstracts/160462/effect-of-polarized-light-therapy-on-oral-mucositis-in-cancer-patients-receiving-chemotherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160462.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">108</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">192</span> Synthesizing an Artificial Loess for Geotechnical Investigations of Collapsible Soil Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Sadeghi">Hamed Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pouya%20A.%20Panahi"> Pouya A.

As a result, research on both geological and geotechnical aspects of this type of soil have been in progress for decades. However, considerable natural variability in physical properties of in-situ loess strata even in a single block sample challenges the fundamental laboratory investigations. The reason behind this is that it is somehow impossible to remove the effect of a specific factor like void ratio from fair comparisons to come with a reliable conclusion. In order to cope with this limitation, two types of artificially made dispersive and calcareous loess are introduced which can be easily reproduced in any soil mechanics laboratory provided that all its compositions are known and controlled. The collapse potential is explored for a variety of soil water salinity and lime content and comparisons are made against the natural soil behavior. Trends are reported for the influence of pore water salinity on collapse potential under different osmotic flow conditions. The most important advantage of artificial loess is the ease of controlling cementing agent content like calcite or dispersive potential for studying their influence on mechanical soil behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20loess" title="artificial loess">artificial loess</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20soils" title=" unsaturated soils"> unsaturated soils</a>, <a href="https://publications.waset.org/abstracts/search?q=collapse%20potential" title=" collapse potential"> collapse potential</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersive%20clays" title=" dispersive clays"> dispersive clays</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20tests" title=" laboratory tests"> laboratory tests</a> </p> <a href="https://publications.waset.org/abstracts/109158/synthesizing-an-artificial-loess-for-geotechnical-investigations-of-collapsible-soil-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109158.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">196</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">191</span> Effects of Acute Exposure to WIFI Signals (2,45 GHz) on Heart Variability and Blood Pressure in Albinos Rabbit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linda%20Saili">Linda Saili</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Hanini"> Amel Hanini</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiraz%20Smirani"> Chiraz Smirani</a>, <a href="https://publications.waset.org/abstracts/search?q=Iness%20Azzouz"> Iness Azzouz</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Azzouz"> Amina Azzouz</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafedh%20Abdemelek"> Hafedh Abdemelek</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihad%20Bouslama"> Zihad Bouslama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrocardiogram and arterial pressure measurements were studied under acute exposures to WIFI (2.45 GHz) during one hour in adult male rabbits. Antennas of WIFI were placed at 25 cm at the right side near the heart. Acute exposure of rabbits to WIFI increased heart frequency (+ 22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that WIFI induced a combined increase of PR and QT intervals. By contrast, the same exposure failed to alter the maximum amplitude and P waves. After intravenously injection of dopamine (0.50 ml/kg) and epinephrine (0.50ml/kg) under acute exposure to RF we found that WIFI alter catecholamines(dopamine, epinephrine) action on heart variability and blood pressure compared to control. These results suggest for the first time, as far as we know, that exposure to WIFI affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radio frequency can act directly and/or indirectly on the cardiovascular system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heart%20rate%20%28HR%29" title="heart rate (HR)">heart rate (HR)</a>, <a href="https://publications.waset.org/abstracts/search?q=arterial%20pressure%20%28PA%29" title=" arterial pressure (PA)"> arterial pressure (PA)</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocardiogram%20%28ECG%29" title=" electrocardiogram (ECG)"> electrocardiogram (ECG)</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20efficacy%20of%0D%0Acatecholamines" title=" the efficacy of catecholamines"> the efficacy of catecholamines</a>, <a href="https://publications.waset.org/abstracts/search?q=dopamine" title=" dopamine"> dopamine</a>, <a href="https://publications.waset.org/abstracts/search?q=epinephrine" title=" epinephrine"> epinephrine</a> </p> <a href="https://publications.waset.org/abstracts/40803/effects-of-acute-exposure-to-wifi-signals-245-ghz-on-heart-variability-and-blood-pressure-in-albinos-rabbit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40803.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">452</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">190</span> Half-Metallic Ferromagnetism in Ternary Zinc Blende Fe/In0.5Ga0.5 as/in Psuperlattice: First-Principles Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Berrouachedi">N.

This compound are found to be half -metallic ferromagnets with a total magnetic moment of 2.25μB per Fe. In addition to this, we reported the DRX measurements of the thick iron sample before and after annealing. One should note, after the annealing treatment at a higher temperature, the disappearance of the peak associated to the Fe(001) plane. In contrast to this report, we observed after the annealing at low temperature the additional peaks attributed to the presence of indium and Fe2As. This suggests a subsequent process consisting in a strong migration of atoms followed with crystallization at the higher temperature.To investigate the origin of magnetism and electronic structure in these zb compounds, we calculated the total and partial DOS of FeInP.One can see that µtotal=4.24µBand µFe=3.27µB in contrast µIn=0.021µB and µP=0.049µB.These results predicted that FeInP compound do belong to the class of zb half metallic HM ferromagnetswith a pseudo gap= 0.93 eVare more promising materials for spintronics devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zincblend%20structure" title="zincblend structure">zincblend structure</a>, <a href="https://publications.waset.org/abstracts/search?q=half%20metallic%20ferromagnet" title=" half metallic ferromagnet"> half metallic ferromagnet</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20moments" title=" spin moments"> spin moments</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20and%20partial%20DOS" title=" total and partial DOS"> total and partial DOS</a>, <a href="https://publications.waset.org/abstracts/search?q=DRX" title=" DRX"> DRX</a>, <a href="https://publications.waset.org/abstracts/search?q=Wien2k" title=" Wien2k"> Wien2k</a> </p> <a href="https://publications.waset.org/abstracts/39717/half-metallic-ferromagnetism-in-ternary-zinc-blende-fein05ga05-asin-psuperlattice-first-principles-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39717.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">272</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">189</span> Engineering in Saudi Arabia: Importance of Communications and Power Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20D.%20Alsharari">Hamed D.

A scheme of work was adopted for an evaluation and characterization of the reproduction of the water nicheurs birds in the marsh of Boussedra. Some important parameters described by the scientific literature; According to standardized methods, variables were the object of a regular follow-up during the period of reproduction. These parameters were taken into account: the installation date of the nests, the vegetable support; blossoming of eggs, causes of the failure of the blossomings (predation or abandonment), characteristics of the nests (composition, internal diameter, external diameter, depth and heightening), measurements of the distances nest-nest nearest, Depth of water, the measurement of eggs, size of laying, size of laying. The follow-up in the marsh was carried out between March 2013 until the month of July 2014 at a rate of two outputs per weeks, one located and noted the nests to control them each week. The study on the reproduction of the water birds enables us to note that this site plays a very important part in the wintering and the reproduction of certain species important.

This city hosts every year, 53 species of waterfowl, belonging to 15 different families, of which the most represented family is the Anatidae with almost 12 species. The Glossy ibis (Plegadis falcinellus) is the only representative of the family of the threskiornithidae. After a total absence for almost a decade, this species has established in North Africa and started breeding since 2000. The Glossy ibis (plegadis falcinellus), breeds with low numbers in distant areas. At the wetland of Boussedra, the population of this species was observed with numbers approaching 160 individuals. During the breeding season of 2014 (between march and july), this species bred in mixed heronries (Cattle egret Bubulcus ibis , Little egret Egretta garzetta, The black-crowned night heron Nycticorax nycticorax , Squacco heron Ardeola ralloides and Little bittern Ixobrychus minutus), where a total of 120 nests were counted. This represents the largest colony observed in North Africa. The reproduction of the studied species took place on a Tamaricaceae (Tamarix gallica), where more than 2000 nest were constructed. During this breeding season, we have monitored the colony's installation and evolution and tried to characterize the reproduction, at the urban water plan of Boussedra (measurements of nests, measurements of eggs and monitoring the growing rate and weight gaining of the chicks, since their birth until their flight). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glossy%20ibis" title="glossy ibis">glossy ibis</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=peri-urban%20wetland" title=" peri-urban wetland"> peri-urban wetland</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20heronry" title=" mixed heronry"> mixed heronry</a>, <a href="https://publications.waset.org/abstracts/search?q=Boussedra" title=" Boussedra"> Boussedra</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria "> Algeria </a> </p> <a href="https://publications.waset.org/abstracts/32423/first-breeding-populations-of-the-glossy-ibis-plegadis-falcinellus-in-a-peri-urban-wetland-areas-marsh-of-boussedra-north-east-of-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32423.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">330</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">182</span> Novel Microstrip MIMO Antenna for 3G/4G Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandro%20Samir%20Nasief">Sandro Samir Nasief</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Hamed%20Ghouz"> Hussein Hamed Ghouz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Fathy"> Mohamed Fathy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A compact ultra-wide band micro-strip MIMO antenna is introduced.

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">180</span> Studying the Impact of Agricultural Producers Support Policy in Export Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yazdani%20Saeed">Yazdani Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafiei%20Hamed"> Rafiei Hamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Nekoofar%20Farahnaz"> Nekoofar Farahnaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Governments Policies play a major role in national and international Markets.

Four rates of Mo (0, 0.01, 0.1 and 1 mg L−1) and five cultivars (MR219, HASHEMI, MR232, FAJRE and MR253) provided the main and sub-plots, respectively. Interaction of molybdenum×variety was significant on shoot phosphorus uptake (p≤0.01). Highest and lowest shoot phosphorus uptake were seen in Mo3V3 (0.6% plant-1) and Mo0V3 (0.14% plant-1) treatments, respectively.

Cyberspace is among the new technologies that need novel ways to address the various issues that have arisen. While cyberspace is a technical notion that defies a single definition, this new technology requires the adoption and application of new laws. In order to manage issues arising from the existence of cyberspace, proper policies and definitions must be formulated which satisfy both technical and legal aspects. One difficulty in this regard is due to the unique features of cyberspace architecture. This article proposes to define cyberspace and cyber terrorism. This will allow for a more effective and comprehensive addressing of legal issues as they can then be handled better by introducing a new factor to the otherwise ordinary analysis in whichever field is implicated such as the nature and place of use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyberspace" title="cyberspace">cyberspace</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20terrorism" title=" cyber terrorism"> cyber terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20definition" title=" technical definition"> technical definition</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20definition" title=" legal definition"> legal definition</a> </p> <a href="https://publications.waset.org/abstracts/24928/technical-and-legal-definitions-in-cyber-terrorism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">589</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">173</span> Development of a Force-Sensing Toothbrush for Gum Recession Measurement Using Programmable Automation Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sorayya%20Kazemi">Sorayya Kazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Kharrati"> Hamed Kharrati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Abedinpour%20Fallah"> Mehdi Abedinpour Fallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the design and implementation of a novel electric pressure-sensitive toothbrush, capable of measuring the forces applied to the head of the brush.

It is presented as a complex process that faces several barriers thereby inhibiting a project’s implementation phase. In fact, after a careful review of the literature, we noticed that empirical researches on reasons behind non-developing entrepreneurial projects are very rare, suggesting a lack in modeling the process in general and the pre-start phase in particular. Therefore, in this study we try to identify the main environmental barriers to developing business projects in Tunisia through the study of a representative sample of undeveloped projects. To this end, we used a quantitative approach which allowed us to examine the various barriers encountered by young entrepreneurs during their projects’ implementation. Indeed, by modeling the phenomenon we found that these managers face barriers of legal, financial, educational and government support dimensions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20barriers" title=" environmental barriers"> environmental barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=non-implementation%20of%20projects" title=" non-implementation of projects"> non-implementation of projects</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20modeling" title=" structural modeling"> structural modeling</a> </p> <a href="https://publications.waset.org/abstracts/40428/limits-and-barriers-of-value-creation-and-projects-development-the-case-of-tunisian-smes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40428.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">381</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">170</span> Presenting a Model Based on Artificial Neural Networks to Predict the Execution Time of Design Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Zolfaghari">Hamed Zolfaghari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Kord"> Mojtaba Kord</a> </p> <p class="card-text"><strong>Abstract:</strong></p> After feasibility study the design phase is started and the rest of other phases are highly dependent on this phase. forecasting the duration of design phase could do a miracle and would save a lot of time.

The results revealed that movement of plunger in the barrel increases when pure silicone is used because non-uniform film is created on the surface of barrel, and also, it seems that the form of silicon is converted from oil to gel due to sterilization process. The results showed that the convenient mixing ratio of solvent/lubricant oil is 80/20. <p class="card-text"><strong>Keywords:</strong> <a
