It has been examined that the intensity of EMIC waves gradually increases by decreasing the L shell. The waves are triggered by hot proton thermal anisotropy. The low-energy cold protons (ions) can be activated by the EMIC waves when the EMIC wave intensity is high. As a result, these previously invisible protons are now visible. As a result, the EMC waves also excite the helium ions. The EMIC waves, whose frequency in the magnetosphere of the Earth ranges from 0.001 Hz to 5 Hz, have drawn a lot of attention for their ability to carry energy. Since these waves act as a mechanism for the loss of energetic electrons from the Van Allen radiation belt to the atmosphere, therefore, it is necessary to understand how and where they can be produced, as well as the direction of waves along the magnetic field lines. This work examines how the excitation of EMIC waves is affected by the energy of hot proton temperature anisotropy, and It has a minimum resonance energy of 6.9 keV and a range of 7 to 26 keV. On the hot protons, however, the reverse effect can be seen for energies below the minimum resonance energy. It is demonstrated that throughout the energy range of 1 eV to 100 eV, the number density and temperature anisotropy of the protons likewise rise as the intensity of the EMIC waves increases. Key Points: 1. The analysis of EMIC waves produced by hot proton temperature anisotropy using MMS data. 2. The number density and temperature anisotropy of the cold protons increases owing to high-intensity EMIC waves. 3. The cold protons with an energy range of 1-100eV are energized by EMIC waves using the Magnetospheric Multiscale (MMS) satellite not been discussed before <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EMIC%20waves" title="EMIC waves">EMIC waves</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20anisotropy%20of%20hot%20protons" title=" temperature anisotropy of hot protons"> temperature anisotropy of hot protons</a>, <a href="https://publications.waset.org/abstracts/search?q=energization%20of%20the%20cold%20proton" title=" energization of the cold proton"> energization of the cold proton</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetospheric%20multiscale%20%28MMS%29%20satellite%20observations" title=" magnetospheric multiscale (MMS) satellite observations"> magnetospheric multiscale (MMS) satellite observations</a> </p> <a href="https://publications.waset.org/abstracts/161623/heating-of-the-ions-by-electromagnetic-ion-cyclotron-emic-waves-using-magnetospheric-multiscale-mms-satellite-observation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161623.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">124</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">1045</span> Energization of the Ions by EMIC Waves using MMS Observation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abid%20Ali%20Abid">Abid Ali Abid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electromagnetic ion cyclotron waves have been playing a significant role in inner magnetosphere, and their proton band has been detected using the Magnetospheric-Multiscale (MMS) satellite observations in the inner magnetosphere.

It seems to offer dosimetric advantages, especially in paediatric central nervous system (CNS) and brain tumours. A short E-survey was conducted to assess the clinical, technical, and educational resources and strategies employed in the state of the art proton beam therapy (PBT) centres in the USA to determine the current status of proton beam therapy. The study also aimed at finding out which PBT skills are in demand as well as what improvements are needed to ensure efficient treatment planning, delivery, and dosimetry. The study resulted in identifying areas for future research and development and in identifying cancers for which PBT is most suitable compared to other modalities to facilitate the implementation and use of PBT in clinical settings for cancer treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity%20modulated%20proton%20therapy" title=" intensity modulated proton therapy"> intensity modulated proton therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20beam%20therapy" title=" proton beam therapy"> proton beam therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20field%20uniform%20scanning" title=" single field uniform scanning"> single field uniform scanning</a> </p> <a href="https://publications.waset.org/abstracts/136847/e-survey-cancer-treatment-with-proton-beam-therapy-in-usa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136847.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">206</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">1043</span> Dynamic Degradation Mechanism of SiC VDMOS under Proton Irradiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junhong%20Feng">Junhong Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenyu%20Lu"> Wenyu Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinhong%20Cheng"> Xinhong Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Zheng"> Li Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuehui%20Yu"> Yuehui Yu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of proton irradiation on the properties of gate oxide were evaluated by monitoring the static parameters (such as threshold voltage and on-resistance) and dynamic parameters (Miller plateau time) of 1700V SiC VDMOS before and after proton irradiation. The incident proton energy was 3MeV, and the doses were 5 × 10¹² P / cm², 1 × 10¹³ P / cm², respectively. The results show that the threshold voltage of MOS exhibits negative drift under proton irradiation, and the near-interface traps in the gate oxide layer are occupied by holes generated by the ionization effect of irradiation, thus forming more positive charges. The basis for selecting TMiller is that the change time of Vgs is the time when Vds just shows an upward trend until it rises to a stable value. The degradation of the turn-off time of the Miller platform verifies that the capacitance Cgd becomes larger, reflecting that the gate oxide layer is introduced into the trap by the displacement effect caused by proton irradiation, and the interface state deteriorates. As a more sensitive area in the irradiation process, the gate oxide layer will be optimized for its parameters (such as thickness, type, etc.) in subsequent studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SiC%20VDMOS" title="SiC VDMOS">SiC VDMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20radiation" title=" proton radiation"> proton radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=Miller%20time" title=" Miller time"> Miller time</a>, <a href="https://publications.waset.org/abstracts/search?q=gate%20oxide" title=" gate oxide"> gate oxide</a> </p> <a href="https://publications.waset.org/abstracts/168374/dynamic-degradation-mechanism-of-sic-vdmos-under-proton-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168374.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">92</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">1042</span> Development of Partial Sulphonated Poly(Vinylidene Fluoride - Hexafluoro Propylene)–Montmorillonite Nano-Composites as Proton Exchange Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Selvakumar">K.

In this case, according to classical theories of physics, radiation and photons, respectively, should be absorbed by the electron. Depending on the number of photons absorbed, the electron radius of rotation around the proton is established. Until now, the principle of photon absorption by electrons and the electron transition to a new energy level, namely to a higher radius of rotation around the proton, is not clarified in physics. This paper aims to demonstrate that photons have mass and negative electrostatic charge similar to electrons but infinitely smaller. The experiments which demonstrate this theory are simple: thermal expansion, photoelectric effect and thermonuclear reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrostatic" title="electrostatic">electrostatic</a>, <a href="https://publications.waset.org/abstracts/search?q=electron" title=" electron"> electron</a>, <a href="https://publications.waset.org/abstracts/search?q=photon" title=" photon"> photon</a>, <a href="https://publications.waset.org/abstracts/search?q=proton" title=" proton"> proton</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation" title=" radiation "> radiation </a> </p> <a href="https://publications.waset.org/abstracts/24883/researches-concerning-photons-as-corpuscles-with-mass-and-negative-electrostatic-charge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24883.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">398</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">1039</span> Passive Heat Exchanger for Proton Exchange Membrane Fuel Cell Cooling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Tolj">Ivan Tolj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water produced during electrochemical reaction in Proton Exchange Membrane (PEM) fuel cell can be used for internal humidification of reactant gases; hydrogen and air. On such a way it is possible to eliminate expensive external humidifiers and simplify fuel cell balance-of-plant (BoP). When fuel cell operates at constant temperature (usually between 60 °C and 80 °C) relatively cold and dry ambient air heats up quickly upon entering channels which cause further drop in relative humidity (below 20%). Low relative humidity of reactant gases dries up polymer membrane and decrease its proton conductivity which results in fuel cell performance drop. It is possible to maintain such temperature profile throughout fuel cell cathode channel which will result in close to 100 % RH. In order to achieve this, passive heat exchanger was designed using commercial CFD software (ANSYS Fluent). Such passive heat exchanger (with variable surface area) is suitable for small scale PEM fuel cells. In this study, passive heat exchanger for single PEM fuel cell segment (with 20 x 1 cm active area) was developed. Results show close to 100 % RH of air throughout cathode channel with increased fuel cell performance (mainly improved polarization curve) and improved durability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PEM%20fuel%20cell" title="PEM fuel cell">PEM fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20heat%20exchange" title=" passive heat exchange"> passive heat exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20management" title=" thermal management"> thermal management</a> </p> <a href="https://publications.waset.org/abstracts/104586/passive-heat-exchanger-for-proton-exchange-membrane-fuel-cell-cooling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104586.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">278</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">1038</span> Comparison Physicochemical Properties of Hexane Extracted Aniseed Oil from Cold Press Extraction Residue and Cold Press Aniseed Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Derya%20%C3%96ren">Derya Ören</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eeyma%20Akal%C4%B1n"> Şeyma Akalın</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cold pres technique is a traditional method to obtain oil.

As from the name itself, the cold spray coating takes place at very low temperature as compare to other thermal spray coatings. In all other thermal spray coating process the partial melting of the coating powder particles takes place before deposition, but cold spray process takes place in solid state. In cold spray process, the bonding of coating power with substrate is not metallurgical as in other thermal spray processes. Due to supersonic speed and less temperature of spray particles, solid state, dense, and oxide free coatings are produced. Due to these characteristics, the cold spray coatings have been used to protect the materials against hot corrosion. In the present study, the cold spray process, cold spray fundaments, its types, and its applications for high temperatures are discussed in the light of presently available literature. In addition, the assessment of cold spray with the competitive technologies has been conferred with available literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20spray%20coating" title="cold spray coating">cold spray coating</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20corrosion" title=" hot corrosion"> hot corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20spray%20coating" title=" thermal spray coating"> thermal spray coating</a>, <a href="https://publications.waset.org/abstracts/search?q=high-temperature%20materials" title=" high-temperature materials "> high-temperature materials </a> </p> <a href="https://publications.waset.org/abstracts/89039/cold-spray-coating-and-its-application-for-high-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89039.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">243</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">1036</span> Calculation of Secondary Neutron Dose Equivalent in Proton Therapy of Thyroid Gland Using FLUKA Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Akbari">M.

The localized tumors, the same as undifferentiated thyroid tumors are insufficiently handled by conventional radiotherapy, while protons would propose the prospect of increasing the tumor dose without exceeding the tolerance of the surrounding healthy tissues. In spite of relatively high advantages in giving localized radiation dose to the tumor region, in proton therapy, secondary neutron production can have significant contribution on integral dose and lessen advantages of this modality contrast to conventional radiotherapy techniques. Furthermore, neutrons have high quality factor, therefore, even a small physical dose can cause considerable biological effects. Measuring of this neutron dose is a very critical step in prediction of secondary cancer incidence. It has been found that FLUKA Monte Carlo code simulations have been used to evaluate dose due to secondaries in proton therapy. In this study, first, by validating simulated proton beam range in water phantom with CSDA range from NIST for the studied proton energy range (34-54 MeV), a proton therapy in thyroid gland cancer was simulated using FLUKA code. Secondary neutron dose equivalent of some organs and tissues after the target volume caused by 34 and 54 MeV proton interactions were calculated in order to evaluate secondary cancer incidence. A multilayer cylindrical neck phantom considering all the layers of neck tissues and a proton beam impinging normally on the phantom were also simulated. Trachea (accompanied by Larynx) had the greatest dose equivalent (1.24×10-1 and 1.45 pSv per primary 34 and 54 MeV protons, respectively) among the simulated tissues after the target volume in the neck region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FLUKA%20code" title="FLUKA code">FLUKA code</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20dose%20equivalent" title=" neutron dose equivalent"> neutron dose equivalent</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20therapy" title=" proton therapy"> proton therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid%20gland" title=" thyroid gland"> thyroid gland</a> </p> <a href="https://publications.waset.org/abstracts/11492/calculation-of-secondary-neutron-dose-equivalent-in-proton-therapy-of-thyroid-gland-using-fluka-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11492.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">425</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">1035</span> Synthesis and Characterization of SiO2/PVA/ SPEEK Composite Membrane for Proton Exchange Membrane Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Yusuf%20Ansari">M.

Although Nafion® is considered as benchmark materials for membrane used in PEM fuel cell, it has limitations that restrict its uses. Alternative materials for the membrane is always a challenging field for researchers. Sulfonated poly(ether ether ketone) (SPEEK) is one of the promising material for membrane due to its chemical and mechanical stability and lower cost. In this work, SPEEK is synthesized, and property booster such as silica nanoparticles and polyvinyl alcohol (PVA) are also added to analyse changes in properties such as water uptake, IEC, and conductivity. It has been found that adding PVA support high water uptake and proton conductivity but at large amount of PVA reduces the proton conductivity due to very high water uptake. Adding silica enhances water uptake and proton conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PEM%20Membrane" title="PEM Membrane">PEM Membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfonated%20poly%20%28ether%20ether%20ketone%29%20%28SPEEK%29" title=" sulfonated poly (ether ether ketone) (SPEEK)"> sulfonated poly (ether ether ketone) (SPEEK)</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fumes%20%28SiO2%29" title=" silica fumes (SiO2)"> silica fumes (SiO2)</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinyl%20alcohol%20%28PVA%29" title=" polyvinyl alcohol (PVA)"> polyvinyl alcohol (PVA)</a> </p> <a href="https://publications.waset.org/abstracts/88749/synthesis-and-characterization-of-sio2pva-speek-composite-membrane-for-proton-exchange-membrane-fuel-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88749.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">285</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">1034</span> Hot Face of Cold War: 007 James Bond</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnevi%20Uslu%20Evren">Günevi Uslu Evren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Propaganda is one of the most effective methods for changing individual and mass opinions. Propaganda tries to get the message across to people or masses to effect rather than to provide objective information. There are many types of propaganda. Especially, political propaganda is a very powerful method that is used by states during in both war and peace. The aim of this method is to create a reaction against them by showing within the framework of internal and external enemies. Propaganda can be practiced by many different methods. Especially during the Cold War Era, the US and USSR have tried to create an ideological effect by using the mass media intensively. Cinema, which is located at the beginning of these methods, is the most powerful weapon to influence the masses. In this study, the historical process of the Cold War is examined. Especially, these propagandas that had been used by United States and The Soviet Union were investigated. The purposes of propaganda and construction methods were presented. Cold War events and relations between the US and the USSR during the Cold War will be discussed. Outlooks of two countries to each other during the Cold War, propaganda techniques used defectively during Cold War and how to use the cinema as a propaganda tool will be examined. The film "From Russia with Love, James Bond 007" that was filmed in Cold War were examined to explain how cinema was used as a propaganda tool in this context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinema" title="cinema">cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20war" title=" cold war"> cold war</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Bond" title=" James Bond"> James Bond</a>, <a href="https://publications.waset.org/abstracts/search?q=propaganda" title=" propaganda"> propaganda</a> </p> <a href="https://publications.waset.org/abstracts/7256/hot-face-of-cold-war-007-james-bond" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7256.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">521</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">1033</span> Effects of ECCS on the Cold-Leg Fluid Temperature during SGTR Accidents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadashi%20Watanabe">Tadashi Watanabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The LSTF experiment simulating the SGTR accident at the Mihama Unit-2 reactor is analyzed using the RELAP5/MOD3.3 code.

Therefore, certain procedures such as; de-energization, verification of de-energization, isolation, lock-out tag-out and earthing are carried out to ensure safe working conditions when conducting maintenance work on de-energized overhead lines. However, measures must be taken to coordinate the above procedures and to ensure successful and accurate execution of those procedures. Issuing of 'Work Permits' is such a measure that is used by the Distribution Utility considered in this paper. Unfortunately, the Work Permit method adopted by the Distribution Utility concerned here has not been successful in creating the safe working conditions as expected which was evidenced by four (4) number of fatalities of workers due to electrocution occurred in the Distribution Utility from 2016 to 2018. Therefore, this paper attempts to identify deficiencies in the Work Permit method and related contributing factors through careful analysis of the four (4) fatalities and work place practices to rectify the short comings to prevent future incidents. The analysis shows that the present level of coordination between the 'Authorized Person' who issues the work permit and the 'Competent Person' who performs the actual work is grossly inadequate to achieve the intended safe working conditions. The paper identifies the need of active participation of a 'Control Person' who oversees the whole operation from a bird’s eye perspective and recommends further measures that are derived through the analysis of the fatalities to address the identified lapses in the current work permit system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=authorized%20person" title="authorized person">authorized person</a>, <a href="https://publications.waset.org/abstracts/search?q=competent%20person" title=" competent person"> competent person</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20person" title=" control person"> control person</a>, <a href="https://publications.waset.org/abstracts/search?q=de-energization" title=" de-energization"> de-energization</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20utility" title=" distribution utility"> distribution utility</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=lock-out%20tag-out" title=" lock-out tag-out"> lock-out tag-out</a>, <a href="https://publications.waset.org/abstracts/search?q=overhead%20lines" title=" overhead lines"> overhead lines</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20permit" title=" work permit"> work permit</a> </p> <a href="https://publications.waset.org/abstracts/102824/improving-electrical-safety-through-enhanced-work-permits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102824.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">133</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">1031</span> Comparison of Water Equivalent Ratio of Several Dosimetric Materials in Proton Therapy Using Monte Carlo Simulations and Experimental Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Akbari">M.

Mirrezaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Range uncertainties of protons are currently a topic of interest in proton therapy. Two of the parameters that are often used to specify proton range are water equivalent thickness (WET) and water equivalent ratio (WER). Since WER values for a specific material is nearly constant at different proton energies, it is a more useful parameter to compare. In this study, WER values were calculated for different proton energies in polymethyl methacrylate (PMMA), polystyrene (PS) and aluminum (Al) using FLUKA and TRIM codes. The results were compared with analytical, experimental and simulated SEICS code data obtained from the literature. In FLUKA simulation, a cylindrical phantom, 1000 mm in height and 300 mm in diameter, filled with the studied materials was simulated. A typical mono-energetic proton pencil beam in a wide range of incident energies usually applied in proton therapy (50 MeV to 225 MeV) impinges normally on the phantom. In order to obtain the WER values for the considered materials, cylindrical detectors, 1 mm in height and 20 mm in diameter, were also simulated along the beam trajectory in the phantom. In TRIM calculations, type of projectile, energy and angle of incidence, type of target material and thickness should be defined. The mode of 'detailed calculation with full damage cascades' was selected for proton transport in the target material. The biggest difference in WER values between the codes was 3.19%, 1.9% and 0.67% for Al, PMMA and PS, respectively. In Al and PMMA, the biggest difference between each code and experimental data was 1.08%, 1.26%, 2.55%, 0.94%, 0.77% and 0.95% for SEICS, FLUKA and SRIM, respectively. FLUKA and SEICS had the greatest agreement (≤0.77% difference in PMMA and ≤1.08% difference in Al, respectively) with the available experimental data in this study. It is concluded that, FLUKA and TRIM codes have capability for Bragg curves simulation and WER values calculation in the studied materials. They can also predict Bragg peak location and range of proton beams with acceptable accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20equivalent%20ratio" title="water equivalent ratio">water equivalent ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=dosimetric%20materials" title=" dosimetric materials"> dosimetric materials</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20therapy" title=" proton therapy"> proton therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulations" title=" Monte Carlo simulations"> Monte Carlo simulations</a> </p> <a href="https://publications.waset.org/abstracts/7211/comparison-of-water-equivalent-ratio-of-several-dosimetric-materials-in-proton-therapy-using-monte-carlo-simulations-and-experimental-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7211.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">326</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">1030</span> The Physics of Cold Spray Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ionel%20Botef">Ionel Botef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies show that, for qualitative coatings, the knowledge of cold spray technology must focus on a variety of interdisciplinary fields and a framework for problem solving.

Nowadays, a huge number of polymers and polymer-mixed various membranes have been investigated for this application, all of which offer both pros and cons. However, PEMFCs are still lack of ideal membranes with unique properties. In this work, carboxymethylcellulose (CMC) based membranes with dispersive graphene oxide (GO) sheets were fabricated and investigated for PEMFCs application. These membranes and pristine GO were studied by a combination of XRD, XPS, Raman, Brillouin, FTIR, thermo-mechanical analysis (TGA and Dynamic Mechanical Analysis) and SEM microscopy, while substantial studies on the proton transport properties were provided by Electrochemical Impedance Spectroscopy (EIS) measurements. It was revealed that the addition of CMC to the GO boosts proton conductivity of the whole membrane, while GO provides good mechanical and thermomechanical stability to the membrane. Further, the continuous and ordered nanochannels with well-tailored chemical structures were obtained by irradiation of heavy ions Kr⁺¹⁷ with an energy of 1.75 MeV/nucleon on the heavy ion accelerator. The formation of these nanochannels led to the significant increase of proton conductivity at 50% Relative Humidity. Also, FTIR and XPS measurement results show that ion irradiation eliminated the GO’s surface oxygen chemical bonds (C=O, C-O), and led to the formation of C = C, C – C bonds, whereas these changes connected with an increase in conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membranes" title="proton exchange membranes">proton exchange membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cells" title=" fuel cells"> fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=carboxymethylcellulose" title=" carboxymethylcellulose"> carboxymethylcellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20irradiation" title=" ion irradiation"> ion irradiation</a> </p> <a href="https://publications.waset.org/abstracts/162499/formation-of-nanochannels-by-heavy-ions-in-graphene-oxide-reinforced-carboxymethylcellulose-membranes-for-proton-exchange-membrane-fuel-cells-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162499.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">92</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">1028</span> Measurement of Reverse Flow Generated at Cold Exit of Vortex Tube </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hazwan%20bin%20Yusof">Mohd Hazwan bin Yusof</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katanoda"> Hiroshi Katanoda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to clarify the structure of the cold flow discharged from the vortex tube (VT), the pressure of the cold flow was measured, and a simple flow visualization technique using a 0.75 mm-diameter needle and an oily paint is made to study the reverse flow at the cold exit.

The GUTs predict the proton decay and, the spontaneous symmetry breaking (SSB) of the higher symmetry group may lead to the formation of topological defects, which are indispensable in the context of the cosmological observations. The Super-Kamiokande (Super-K) experiment sets sacrosanct bounds on the partial lifetime (τ) of the proton decay for different channels, e.g., τ(p → e+ π0) > 1.6×10³⁴ years which is the most relevant channel to test the viability of the nonsupersymmetric GUTs. The GUTs based on the gauge groups SO(10) and E(6) are broken to the SM spontaneously through one and two intermediate gauge symmetries with the manifestation of the left-right symmetry at least at a single intermediate stage and the proton lifetime for these breaking chains has been computed. The impact of the threshold corrections, as a consequence of integrating out the heavy fields at the breaking scale alter the running of the gauge couplings, which eventually, are found to keep many GUTs off the Super-K bound. The possible topological defects arising in the course of SSB at different breaking scales for all breaking chains have been studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grand%20unified%20theories" title="grand unified theories">grand unified theories</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20decay" title=" proton decay"> proton decay</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20correction" title=" threshold correction"> threshold correction</a>, <a href="https://publications.waset.org/abstracts/search?q=topological%20defects" title=" topological defects"> topological defects</a> </p> <a href="https://publications.waset.org/abstracts/109130/effect-of-threshold-corrections-on-proton-lifetime-and-emergence-of-topological-defects-in-grand-unified-theories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109130.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">177</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">1026</span> Optimum Design of Heat Exchanger in Diesel Engine Cold EGR for Pollutants Reduction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasser%20Ghassembaglou">Nasser Ghassembaglou</a>, <a href="https://publications.waset.org/abstracts/search?q=Armin%20Rahmatfam"> Armin Rahmatfam</a>, <a href="https://publications.waset.org/abstracts/search?q=Faramarz%20Ranjbar"> Faramarz Ranjbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using of cold EGR method with variable venturi and turbocharger has a very significant affection on the reduction of NOX and grime simultaneously.

Due to low mechanical stability, flooding and fuel cell crossover, application of phosphoric acid in polymeric membrane is very critical. Phosphorous and silica based 3D inorganic gel gains the attention in the field of supercapacitors, fuel cells and metal hydrate batteries due to its thermally stable highly proton conductive behavior. Also as a large amount of water molecule and phosphoric acid can easily get trapped in Si-O-Si network cavities, it causes a prevention in the leaching out. In this study, we have performed molecular dynamics (MD) simulation and first principle calculations to understand the structural, electronics and electrochemical and morphological behavior of this inorganic gel at various P to Si ratios. We have used dipole-dipole interactions, H bonding, and van der Waals forces to study the main interactions between the molecules. A 'structure property-performance' mapping is initiated to determine optimum P to Si ratio for best proton conductivity. We have performed the MD simulations at various temperature to understand the temperature dependency on proton conductivity. The observed results will propose a model which fits well with experimental data and other literature values. We have also studied the mechanism behind proton conductivity. And finally we have proposed a structure for the gel paste with optimum P to Si ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=first%20principle%20calculation" title="first principle calculation">first principle calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorous%20and%20silica%20based%203D%20inorganic%20gel" title=" phosphorous and silica based 3D inorganic gel"> phosphorous and silica based 3D inorganic gel</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20electrolyte%20membrane%20fuel%20cells" title=" polymer electrolyte membrane fuel cells"> polymer electrolyte membrane fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20conductivity" title=" proton conductivity"> proton conductivity</a> </p> <a href="https://publications.waset.org/abstracts/101031/study-of-structural-behavior-and-proton-conductivity-of-inorganic-gel-paste-electrolyte-at-various-phosphorous-to-silicon-ratio-by-multiscale-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101031.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">129</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">1022</span> Residual Life Estimation of K-out-of-N Cold Standby System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qian%20Zhao">Qian Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shi-Qi%20Liu"> Shi-Qi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Guo"> Bo Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhi-Jun%20Cheng"> Zhi-Jun Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiao-Yue%20Wu"> Xiao-Yue Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cold standby redundancy is considered to be an effective mechanism for improving system reliability and is widely used in industrial engineering.

Therefore, the response of these detectors to hadron beams is highly of interest in radiation therapy (RT) using ion beams. In this study, these detectors' responses to proton and Helium-4 ion beams were compared using Monte Carlo simulations. The calculated data for proton beams were compared with Markus ionization chamber (IC) measurement (in water phantom) from M.D. Anderson proton therapy center. Monte Carlo simulations were performed via the FLUKA code (version 2011.2-17). The detectors were modeled in cylindrical shape at various depths of the water phantom without shading each other for obtaining relative depth dose in the phantom. Mono-energetic parallel ion beams in different incident energies (100 MeV/n to 250 MeV/n) were collided perpendicularly on the phantom surface. For proton beams, the results showed that the simulated detectors have over response relative to IC measurements in water phantom. In all cases, there were good agreements between simulated ion ranges in the water with calculated and experimental results reported by the literature. For proton, maximum peak to entrance dose ratio in the simulated water phantom was 4.3 compared with about 3 obtained from IC measurements. For He-4 ion beams, maximum peak to entrance ratio calculated by both detectors was less than 3.6 in all energies. Generally, it can be said that FLUKA is a good tool to calculate Al2O3:C,Mg FNTD and Al2O3:C OSLD detectors responses to therapeutic proton and He-4 ion beams. It can also calculate proton and He-4 ion ranges with a reasonable accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparison" title="comparison">comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=FNTD%20and%20OSLD%20detectors%20response" title=" FNTD and OSLD detectors response"> FNTD and OSLD detectors response</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20ion%20beams" title=" light ion beams"> light ion beams</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulations" title=" Monte Carlo simulations"> Monte Carlo simulations</a> </p> <a href="https://publications.waset.org/abstracts/7133/comparison-of-fntd-and-osld-detectors-responses-to-light-ion-beams-using-monte-carlo-simulations-and-exprimental-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7133.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">343</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">1020</span> The Impact of the “Cold Ambient Color = Healthy” Intuition on Consumer Food Choice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yining%20Yu">Yining Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bingjie%20Li"> Bingjie Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Miaolei%20Jia"> Miaolei Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Wang"> Lei Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ambient color temperature is one of the most ubiquitous factors in retailing. However, there is limited research regarding the effect of cold versus warm ambient color on consumers’ food consumption. This research investigates an unexplored lay belief named the “cold ambient color = healthy” intuition and its impact on food choice. We demonstrate that consumers have built the “cold ambient color = healthy” intuition, such that they infer that a restaurant with a cold-colored ambiance is more likely to sell healthy food than a warm-colored restaurant. This deep-seated intuition also guides consumers’ food choices. We find that using a cold (vs. warm) ambient color increases the choice of healthy food, which offers insights into healthy diet promotion for retailers and policymakers. Theoretically, our work contributes to the literature on color psychology, sensory marketing, and food consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambient%20color%20temperature" title="ambient color temperature">ambient color temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20ambient%20color" title=" cold ambient color"> cold ambient color</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20choice" title=" food choice"> food choice</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20wellbeing" title=" consumer wellbeing"> consumer wellbeing</a> </p> <a href="https://publications.waset.org/abstracts/148864/the-impact-of-the-cold-ambient-color-healthy-intuition-on-consumer-food-choice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148864.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">144</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">1019</span> Radiation Stability of Pigment ZnO Modified by Nanopowders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chundong%20Li">Chundong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20V.%20Neshchimenko"> V.

It has been established that the introduction of nanoparticles ZrO2, Al2O3 enhances the optical stability of the pigments under proton irradiation, but reduces it under electron irradiation. Modifying with TiO2, SiO2, CeO2, Y2O3 nanopowders leads to decrease radiation stability in both types of irradiation. Samples modified by 5 wt. % of ZrO2 nanoparticles have the highest stability of optical properties after proton exposure. The degradation of optical properties under electron irradiation is not high for this concentration of nanoparticles. A decrease in the absorption of pigments modified with nanoparticles proton exposure is determined by a decrease in the intensity of bands located in the UV and visible regions.

The spin of a rotating structure is assumed to be equal to 3/2, while the spin of a 'bare' electron is equal to unity, the resultant spin being 1/2. A simple analysis gives the coefficients for a linear combination of proton and electron masses, the approximation precision giving here nine significant digits after the decimal point. The summand proportional to α² adds four more digits. Thus, the conception of the effective mass Meff leads to the formula for the total magnetic moment of the electron, which is accurate to fourteen digits. Association with the virtual beta-decay reaction and possible reasons for simplicity of the derived formula are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anomalous%20magnetic%20moment%20of%20electron" title="anomalous magnetic moment of electron">anomalous magnetic moment of electron</a>, <a href="https://publications.waset.org/abstracts/search?q=comparison%20with%20quantum%20electrodynamics.%20effective%20%20mass" title=" comparison with quantum electrodynamics. effective mass"> comparison with quantum electrodynamics. effective mass</a>, <a href="https://publications.waset.org/abstracts/search?q=fifteen%20significant%20figures" title=" fifteen significant figures"> fifteen significant figures</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20and%20neutron%20masses" title=" proton and neutron masses"> proton and neutron masses</a> </p> <a href="https://publications.waset.org/abstracts/131423/relation-of-the-anomalous-magnetic-moment-of-electron-with-the-proton-and-neutron-masses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131423.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">123</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">1017</span> The Impact of Ambient Temperature on Consumer Food Choice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yining%20Yu">Yining Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Miaolei%20Jia"> Miaolei Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Bingjie%20Li"> Bingjie Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While researchers have begun to investigate how ambient elements affect consumers’ choices between healthy and unhealthy food, the role of ambient temperature is relatively unknown. In this study, we find that ambient coldness increases consumers’ preference for unhealthy food. This effect is driven by the increased need for energy automatically activated in a cold ambiance. Consequently, consumers are more inclined to choose calorie-rich unhealthy food. This effect is diminished when the unhealthy food is cold because cold dish cannot provide the energy consumers need in the cold ambiance. We conclude with a discussion of our theoretical contributions to the literature of temperature effects and food consumption. We also offer practical takeaways for restaurant managers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambient%20temperature"
