Moroccan Atlantic sea was subjected to the pressure of the bottom trawling, one of the most destructive techniques seabed that cause havoc on fishing catch, nonselective, and responsible for more than half of all releases of fish around the world. The present paper aims to map and assess the impact of the activity of the bottom trawling of the Moroccan Atlantic coast. For this purpose, a dataset of thirty years, between 1962 and 1999, from foreign fishing vessels using bottom trawling, has been used and integrated in a GIS. To estimate the extent and the importance of the geographical distribution of the trawling effort, the Moroccan Atlantic area was divided into a grid of cells of 25 km2 (5x5 km). This grid was joined to the effort trawling data, creating a new entity with a table containing spatial overlay grid with the polygon of swept surfaces. This mapping model allowed to quantify the used fishing effort versus time and to generate the trace indicative of trawling efforts on the seabed. Indeed, for a given year, a grid cell may have a swept area equal to 0 (never been touched by the trawl) or 25 km2 (the trawled area is similar to the cell size) or may be 100 km2 indicating that for this year, the scanned surface is four times the cell area. The results show that the total cumulative sum of trawled area is approximately 28,738,326 km2, scattered throughout the Atlantic coast. 95% of the overall trawling effort is located in the southern zone, between 29°N and 20°30'N. Nearly 5% of the trawling effort is located in the northern coastal region, north of 33°N. The center area between 33°N and 29°N is the least swept by Russian commercial vessels because in this region the majority of the area is rocky, and non trawlable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GIS" title="GIS">GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=Moroccan%20Atlantic%20Ocean" title=" Moroccan Atlantic Ocean"> Moroccan Atlantic Ocean</a>, <a href="https://publications.waset.org/abstracts/search?q=seabed" title=" seabed"> seabed</a>, <a href="https://publications.waset.org/abstracts/search?q=trawling" title=" trawling"> trawling</a> </p> <a href="https://publications.waset.org/abstracts/45380/assessment-of-the-impact-of-trawling-activities-on-marine-bottoms-of-moroccan-atlantic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45380.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">328</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">434</span> Pair Interaction in Transition-Metal Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikolay%20E.%20Dubinin">Nikolay E.

At the same time, description of an effective pair interaction in transition metal is a hard task since the d-electron contribution to the potential energy in this case is non-pairwise in principle. There are a number of models for transition-metal effective pair potentials. Here we use the Wills-Harrison (WH) approach to calculate pair potentials for Fe, Co, and Ni in crystalline, liquid, and nano states. Last is especially interesting since nano particles of pure transition metals immobilized on the dielectric matrices are widely used in different fields of advanced technologies: as carriers and transmitters of information, as an effective catalytic materials, etc. It is found that the minimum of the pair potential is deeper and oscillations are stronger in nano crystalline state in comparison with the liquid and crystalline states for all metals under consideration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effective%20pair%20potential" title="effective pair potential">effective pair potential</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocrystalline%20state" title=" nanocrystalline state"> nanocrystalline state</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20metal" title=" transition metal"> transition metal</a>, <a href="https://publications.waset.org/abstracts/search?q=Wills-Harrison%20approach" title=" Wills-Harrison approach "> Wills-Harrison approach </a> </p> <a href="https://publications.waset.org/abstracts/14984/pair-interaction-in-transition-metal-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14984.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">385</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">433</span> Challenges of Sustainable Marine Fishing in Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20K.%20W.%20Aikins">Eric K. W. Aikins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditionally, Ghana is a marine fishing country. The fishing industry dominated by artisanal marine fishing helps Ghana to meet its fish and protein requirements. Also, it provides employment for most coastal dwellers that depend on fishing as their main economic enterprise. Nonetheless, the marine fishing industry is confronted with challenges that have contributed to a declining fish production in recent past decade. Bad fishing practices and the general limited knowledge on sustainable management of fisheries resources are the limiting factors that affect sustainable fish production and sustainable marine biodiversity management in Ghana. This paper discusses the challenges and strategies for attaining and maintaining sustainable marine fishing in Ghana as well as the state of marine fishing in Ghana. It concludes that an increase in the level of involvement of local fishers in the management of fisheries resources of the country could help local fishers to employ sustainable fisheries resources exploitation methods that could result in an improvement in the spatio-economic development and wellbeing of affected fishing communities in particular and Ghana in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pair%20trawling" title="pair trawling">pair trawling</a>, <a href="https://publications.waset.org/abstracts/search?q=sargassum" title=" sargassum"> sargassum</a>, <a href="https://publications.waset.org/abstracts/search?q=spatio-economic%20development" title=" spatio-economic development"> spatio-economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20marine%20fishing" title=" sustainable marine fishing"> sustainable marine fishing</a> </p> <a href="https://publications.waset.org/abstracts/86329/challenges-of-sustainable-marine-fishing-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">432</span> A Golay Pair Based Synchronization Algorithm for Distributed Multiple-Input Multiple-Output System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weizhi%20Zhong">Weizhi Zhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyi%20Lu"> Xiaoyi Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Xu"> Lei Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to solve the problem of inaccurate synchronization for distributed multiple-input multiple-output (MIMO) system in multipath environment, a golay pair aided timing synchronization method is proposed in this paper.

The two allowed atomic transitions are interacting resonantly with two laser ﬁelds. For unbalanced coupling, it is possible to derive an explicit solution for non-linear differential equations describing the soliton-pair propagation in this three-level system with the same velocity. We suppose that the spontaneous emission rates from the excited state to both ground states are the same. In this work, we focus on such case where we consider the coupling between the transitions and the optical ﬁelds are unbalanced. The existence conditions for the soliton-pair propagations are determined. We will show that there are four possible configurations of the soliton-pair pulses. Two of them can be interpreted as a couple of solitons with same directions of polarization and the other two as soliton-pair with opposite directions of polarization. Due to the fact that solitons have stable shapes while propagating in the considered media, they are insensitive to noise and dispersion. Our results have potential applications in data transfer with the soliton-pair pulses, where a dissipative three-level medium could be a realistic model for the optical communication media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-linear%20differential%20equations" title="non-linear differential equations">non-linear differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=solitons" title=" solitons"> solitons</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20propagations" title=" wave propagations"> wave propagations</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20fiber" title=" optical fiber"> optical fiber</a> </p> <a href="https://publications.waset.org/abstracts/108578/analytic-solutions-of-solitary-waves-in-three-level-unbalanced-dense-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108578.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">430</span> Combined Odd Pair Autoregressive Coefficients for Epileptic EEG Signals Classification by Radial Basis Function Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boukari%20Nassim">Boukari Nassim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the use of odd pair autoregressive coefficients (Yule _Walker and Burg) for the feature extraction of electroencephalogram (EEG) signals.

The RBFNN is described by his architecture and his characteristics: as the RBF is defined by the spread which is modified for improving the results of the classification. Five types of EEG signals are defined for this work: Set A, Set B for normal signals, Set C, Set D for interictal signals, set E for ictal signal (we can found that in Bonn university).

The subjects were instructed to listen to English songs they liked on YouTube, especially paying attention to phonologically similar vowel and consonant minimal pair words (e.g., live and leave). This kind of activity, which included taking notes, was regularly carried out in the classroom, and the same kind of task was given to the subjects as homework in order to reinforce the in-class activity. The duration of these activities was eight weeks, after which the program was evaluated on a 9-point scale (1: the lowest and 9: the highest) by learners’ self-evaluation. The main questions for this evaluation included 1) how good the learners had been at pronouncing vowel and consonant minimal pair words originally, 2) how often they had listened to songs good for pronouncing vowel and consonant minimal pair words, 3) how frequently they had moved their mouths to vowel and consonant minimal pair words of English songs, and 4) how much they thought the program would support and enhance their pronunciation learning of phonologically similar vowel and consonant minimal pair words. It has been found, for example, A) that the evaluation of this program is by no means low (Mean: 6.51 and SD: 1.23), suggesting that listening to music may support and enhance pronunciation learning, and B) that listening to consonant minimal pair words in English songs and moving the mouth to them are more related to the program’s evaluation (r =.69, p=.00 and r =.55, p=.00, respectively) than listening to vowel minimal pair words in English songs and moving the mouth to them (r =.45, p=.00 and r =.39, p=.01, respectively). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimal%20pair" title="minimal pair">minimal pair</a>, <a href="https://publications.waset.org/abstracts/search?q=music" title=" music"> music</a>, <a href="https://publications.waset.org/abstracts/search?q=pronunciation" title=" pronunciation"> pronunciation</a>, <a href="https://publications.waset.org/abstracts/search?q=song" title=" song"> song</a> </p> <a href="https://publications.waset.org/abstracts/7949/understanding-relationships-between-listening-to-music-and-pronunciation-learning-an-investigation-based-upon-japanese-efl-learners-self-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7949.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">318</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">428</span> The Fit of the Partial Pair Distribution Functions of BaMnFeF7 Fluoride Glass Using the Buckingham Potential by the Hybrid RMC Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidi%20Mohamed%20Mesli">Sidi Mohamed Mesli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Habchi"> Mohamed Habchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arslane%20Boudghene%20Stambouli"> Arslane Boudghene Stambouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Benallal"> Rafik Benallal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The BaMnMF7 (M=Fe,V, transition metal fluoride glass, assuming isomorphous replacement) have been structurally studied through the simultaneous simulation of their neutron diffraction patterns by reverse Monte Carlo (RMC) and by the Hybrid Reverse Monte Carlo (HRMC) analysis. This last is applied to remedy the problem of the artificial satellite peaks that appear in the partial pair distribution functions (PDFs) by the RMC simulation. The HRMC simulation is an extension of the RMC algorithm, which introduces an energy penalty term (potential) in acceptance criteria. The idea of this work is to apply the Buckingham potential at the title glass by ignoring the van der Waals terms, in order to make a fit of the partial pair distribution functions and give the most possible realistic features. When displaying the partial PDFs, we suggest that the Buckingham potential is useful to describe average correlations especially in similar interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluoride%20glasses" title="fluoride glasses">fluoride glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=RMC%20simulation" title=" RMC simulation"> RMC simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20RMC%20simulation" title=" hybrid RMC simulation"> hybrid RMC simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Buckingham%20potential" title=" Buckingham potential"> Buckingham potential</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20pair%20distribution%20functions" title=" partial pair distribution functions"> partial pair distribution functions</a> </p> <a href="https://publications.waset.org/abstracts/38108/the-fit-of-the-partial-pair-distribution-functions-of-bamnfef7-fluoride-glass-using-the-buckingham-potential-by-the-hybrid-rmc-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38108.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">503</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">427</span> Mass Polarization in Three-Body System with Two Identical Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Filikhin">Igor Filikhin</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20M.%20Suslov"> Vladimir M.

The systems are well clustering as A+ (A+B) with a ground state energy E2 for the pair A+B. The calculations are performed using the method of the Faddeev equations in configuration space. The phenomenological pair potentials were used. We show a correlation between the mass ratio mA/mB and the value δB of the mass-polarization term. For bosonic-like systems, this value is defined as δB = 2E2 − E3, where E3 is three-body energy when VAA = 0. For the systems including three particles with spin(isospin), the models with average AB-potentials are used. In this case, the Faddeev equations become a scalar one like for the bosonic-like system αΛΛ. We show that the additional energy conected with the mass-polarization term can be decomposite to a sum of the two parts: exchenge related and reduced mass related. The state of the system can be described as the following: the particle A1 is bound within the A + B pair with the energy E2, and the second particle A2 is bound with the pair with the energy E3 − E2. Due to the identity of A particles, the particles A1 and A2 are interchangeable in the pair A + B. We shown that the mass polarization δB correlates with a type of AB potential using the system αΛΛ as an example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=three-body%20systems" title="three-body systems">three-body systems</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20polarization" title=" mass polarization"> mass polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=Faddeev%20equations" title=" Faddeev equations"> Faddeev equations</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20interactions" title=" nuclear interactions"> nuclear interactions</a> </p> <a href="https://publications.waset.org/abstracts/46186/mass-polarization-in-three-body-system-with-two-identical-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46186.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">377</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">426</span> Designing and Simulation of a CMOS Square Root Analog Multiplier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milad%20Kaboli">Milad Kaboli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new CMOS low voltage current-mode four-quadrant analog multiplier based on the squarer circuit with voltage output is presented.

To date, much research on pair interaction in L2 collaborative writing settings has centered on intermediate and advanced learners by using static categorization of pair interaction patterns. Little is known about the fluid nature of pair interaction during collaborative writing, especially among low-proficiency learners. This study, thus, is aimed to explore the interaction dynamics of low-proficiency L2 learners during collaborative writing via examining the interaction pattern, focus of interaction, and the language related episodes (LREs) of 5 low-proficiency L2 writers from Taiwan. Employing a micro-level functional analytical method to capture the changing nature of pair interaction dynamics, the researchers calculated the number of characters/words produced by each pair member during CW and then classified their utterances into four task related-aspects--content, organization, language use, and task management--to determine each pair member's relative contribution to different dimensions of the evolving text. The LREs were also identified and examined. The results show that, of the five pairs, three pairs changed their interaction patterns when discussing different aspects of writing. Regarding the focus of their interaction, all five pairs paid attention to content most, followed by language use, task management, and organization. They were able to successfully resolve the majority of language issues (75.2%) in LREs and use the correct forms in their writing. These findings lend support to the fluid nature of pairs’ interactions and the changing roles of L2 learners in collaborative writing and highlighted the necessity of examining learners’ interaction patterns from a micro-level perspective. These findings also support previous research that low-proficiency pairs are able to correctly revolve 2/3 of their produced LREs, suggesting that collaborative writing may also be suitable for L2 low-proficiency learners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20writing" title="collaborative writing">collaborative writing</a>, <a href="https://publications.waset.org/abstracts/search?q=low-proficiency%20L2%20learners" title=" low-proficiency L2 learners"> low-proficiency L2 learners</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-level%20functional%20analysis" title=" micro-level functional analysis"> micro-level functional analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=pair%20interaction%20pattern" title=" pair interaction pattern"> pair interaction pattern</a> </p> <a href="https://publications.waset.org/abstracts/153963/low-proficiency-l2-learners-dyadic-interactions-in-collaborative-writing-an-exploratory-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153963.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">130</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">424</span> Active Learning Techniques in Engineering Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20M.%20Anitha">H.

New delivery methods are proposed which is an added feature to the engineering education. Particularly, more importance is given to new teaching practices such as Information and Communication Technologies (ICT). It is vital to adopt the new ICT methods which lead to the emergence of novel structure and mode of education. The flipped classroom, think pair share and peer instruction are the latest pedagogical methods which give students to learn the course. This involves students to watch video lectures outside the classroom and solve the problems at home. Students are engaged in group discussions in the classroom. These are the active learning methods wherein the students are involved diversely to learn the course. This paper gives a comprehensive study of past and present research which is going on with flipped classroom, thinks pair share activity and peer instruction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flipped%20classroom" title="flipped classroom">flipped classroom</a>, <a href="https://publications.waset.org/abstracts/search?q=think%20pair%20share" title=" think pair share"> think pair share</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20instruction" title=" peer instruction"> peer instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20learning" title=" active learning"> active learning</a> </p> <a href="https://publications.waset.org/abstracts/19317/active-learning-techniques-in-engineering-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19317.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">386</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">423</span> A Preliminary Study for Building an Arabic Corpus of Pair Questions-Texts from the Web: Aqa-Webcorp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wided%20Bakari">Wided Bakari</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrce%20Bellot"> Patrce Bellot</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Neji"> Mahmoud Neji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the development of electronic media and the heterogeneity of Arabic data on the Web, the idea of building a clean corpus for certain applications of natural language processing, including machine translation, information retrieval, question answer, become more and more pressing.

In order to enhance the inertia, virtual synchronous generator (VSG) has been proposed. In addition, the motor-generator pair (MGP) system is proposed to enhance grid inertia. Both of them need additional equipment to provide instantaneous energy, so the economic problem should be considered. In this paper, the basic working principle of MGP system and VSG are introduced firstly. Then, the technical characteristics and economic investment of MGP/VSG are compared by calculation and simulation.

In particular, we examine the differences between base pair substitution induction by ionizing radiation in model haploid and diploid yeast <em>Saccharomyces cerevisiae</em> cells. Such mutations are difficult to study in higher eukaryotic systems. In our research, we have used a collection of six isogenic <em>trp5</em>-strains and 14 isogenic haploid and diploid <em>cyc1</em>-strains that are specific markers of all possible base-pair substitutions. These strains differ from each other only in single base substitutions within codon-50 of the <em>trp5</em> gene or codon-22 of the <em>cyc1</em> gene. Different mutation spectra for two different haploid genetic <em>trp5</em>- and <em>cyc1</em>-assays and different mutation spectra for the same genetic <em>cyc1</em>-system in cells with different ploidy — haploid and diploid — have been obtained. It was linear function for dose-dependence in haploid and exponential in diploid cells. We suggest that the differences between haploid yeast strains reflect the dependence on the sequence context, while the differences between haploid and diploid strains reflect the different molecular mechanisms of mutations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20pair%20substitutions" title="base pair substitutions">base pair substitutions</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B3-rays" title=" γ-rays"> γ-rays</a>, <a href="https://publications.waset.org/abstracts/search?q=haploid%20and%20diploid%20cells" title=" haploid and diploid cells"> haploid and diploid cells</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast%20Saccharomyces%20cerevisiae" title=" yeast Saccharomyces cerevisiae"> yeast Saccharomyces cerevisiae</a> </p> <a href="https://publications.waset.org/abstracts/91922/all-types-of-base-pair-substitutions-induced-by-gh-rays-in-haploid-and-diploid-yeast-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91922.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">420</span> Node Pair Selection Scheme in Relay-Aided Communication Based on Stable Marriage Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tetsuki%20Taniguchi">Tetsuki Taniguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshio%20Karasawa"> Yoshio Karasawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a node pair selection scheme in relay-aided multiple source multiple destination communication system based on stable marriage problem.

A numerical analysis of thermal and solar performances of an annular finned adsorber, which is the most important component of the adsorption solar refrigerating system, is considered in this work. Different adsorbent/adsorbate pairs, such as activated carbon AC35/methanol, activated carbon AC35/ethanol, and activated carbon BPL/Ammoniac, are undertaken in this study. The modeling of the adsorption cooling machine requires the resolution of the equation describing the energy and mass transfer in the tubular finned adsorber. The Wilson and Dubinin- Astakhov models of the solid-adsorbate equilibrium are used to calculate the adsorbed quantity. The porous medium and the fins are contained in the annular space, and the adsorber is heated by solar energy. Effects of key parameters on the adsorbed quantity and on the thermal and solar performances are analysed and discussed. The AC35/methanol pair is the best pair compared to BPL/Ammoniac and AC35/ethanol pairs in terms of system performance. The system performances are sensitive to the fin geometry. For the considered data measured for clear type days of July 2023 in Algeria and Morocco, the performances of the cooling system are very significant in Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon%20AC35-methanol%20pair" title="activated carbon AC35-methanol pair">activated carbon AC35-methanol pair</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon%20AC35-ethanol%20pair" title=" activated carbon AC35-ethanol pair"> activated carbon AC35-ethanol pair</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon%20BPL-ammoniac%20pair" title=" activated carbon BPL-ammoniac pair"> activated carbon BPL-ammoniac pair</a>, <a href="https://publications.waset.org/abstracts/search?q=annular%20finned%20adsorber" title=" annular finned adsorber"> annular finned adsorber</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20coefficients" title=" performance coefficients"> performance coefficients</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cooling%20system" title=" solar cooling system"> solar cooling system</a> </p> <a href="https://publications.waset.org/abstracts/183276/numerical-analysis-of-solar-cooling-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183276.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">55</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">415</span> Fokas-Lenells Equation Conserved Quantities and Landau-Lifshitz System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riki%20Dutta">Riki Dutta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sagardeep%20Talukdar"> Sagardeep Talukdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautam%20Kumar%20Saharia"> Gautam Kumar Saharia</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudipta%20Nandy"> Sudipta Nandy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fokas-Lenells equation (FLE) is one of the integrable nonlinear equations use to describe the propagation of ultrashort optical pulses in an optical medium.

However, it is specialized in feeding on crucifer aphid, Brevicoryne brassicae. Biological potential of parasitoid is its density-dependency due to sharing of limited resources in few cases. The present study was carried out to check the biotic potential of D. rapae at its different densities (1, 2, 4, 8 and 10 pairs) on fixed number of B. brassicae (100 in number) as a host. The present study was performed under laboratory conditions (25 ± 2 ºC temperature and 65-70 % R.H.). Different biological parameters for parasitoid (e.g. percent parasitism, adult emergence, adult longevity and per pair parasitism) were evaluated to check its biotic potential. The present findings showed that maximum parasitism (43.09 % ± 0.63) was observed in highest density (10 pairs) and minimum parasitism (16.59 % ± 1.28) in lowest density (1 pair) of the parasitoid. Maximum adult emergence (80.31 % ± 1.33) was observed in highest density (10 pairs) and minimum parasitism (45.99 % ± 1.27) in lowest density (1 pair) of the parasitoid. In the case of adult longevity, highest (8.2 days ± 0.38) and lowest (6 days ± 0.32) longevity were observed in lowest (1 pair) and highest (10 pairs) densities of parasitoids respectively. However, per pair parasitism rate decreased with the increase in parasitoid densities due to intra-specific competition, developed between the parasitoids for parasitism. The positive but close relationship was observed between percent parasitism and adult emergence. The increase in parasitoid densities increased the percent parasitism and adult emergence of the parasitoid. So, we conclude that an inter-specific competition negatively affected the efficacy of parasitoids and may reduce the fitness of the emerging parasitoid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diaeretiella%20rapae" title="Diaeretiella rapae">Diaeretiella rapae</a>, <a href="https://publications.waset.org/abstracts/search?q=Parasitoid%20densities" title=" Parasitoid densities"> Parasitoid densities</a>, <a href="https://publications.waset.org/abstracts/search?q=Percent%20parasitism" title=" Percent parasitism"> Percent parasitism</a>, <a href="https://publications.waset.org/abstracts/search?q=adult%20emergence" title=" adult emergence"> adult emergence</a> </p> <a href="https://publications.waset.org/abstracts/74543/biotic-potential-of-different-densities-of-aphid-parasitoids-diaeretiella-rapae-hymenoptera-braconidae-aphidiinae-feeding-on-brevicoryne-brassicae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74543.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">234</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">413</span> Experience of Hydatid Disease of Liver at a Tertiary Care Center 7 Years Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jibran%20Abbasy">Jibran Abbasy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Sultan"> Rizwan Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Humayun"> Ammar Humayun</a>, <a href="https://publications.waset.org/abstracts/search?q=Tabish%20Chawla"> Tabish Chawla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Hydatid disease caused by Echinococcus Granulosus affects liver in 70-90% of cases. Dogs are the definitive host while humans are the accidental host. Modalities used for its treatment are especially important for our population as the disease is endemic in many Asian countries. The aim of the study was to perform an audit of the various modalities used for treatment of hydatid disease of liver and the response to each modality in tertiary care center of Pakistan. Materials and Methods: Retrospective audit of patients diagnosed and treated for Hydatid disease of the liver at Aga Khan University Hospital from 1st January 2007 to 31st December 2014 was completed. All patients aged 16 and above were included. Patients who had extra hepatic disease and missing records were excluded. Outcome measures were morbidity, mortality and recurrence of the disease. Results: During the study period 56 patients were treated for isolated hepatic hydatid disease and were included. Mean age was 39 years with 48% being females and 52% males. Most common presenting complaint was abdominal pain seen in 53% of patients(n=41). Duration of symptoms was less than 6 months in 74% (n=38). Mostly right lobe was involved in 69% (n=38).Most common treatment modality used was surgery in 34 patients followed by PAIR in 14 patients while 8 patients were treated medically. At a median follow up of 34 months recurrence was seen in 2 patients treated with PAIR while no patient treated with surgery had recurrence with the median follow up of 20 months. While no morbidity and mortality were observed in PAIR, but in surgery 5 patients had morbidity while 1 patient had mortality. Conclusion: Our data is comparative to other studies in terms of morbidity, mortality, and recurrence. We had adequate follow up. In our study PAIR and surgery both are effective and have less complications and recurrence rate. Surgery is still the gold standard in terms of recurrence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=echinococcous%20granulosus" title="echinococcous granulosus">echinococcous granulosus</a>, <a href="https://publications.waset.org/abstracts/search?q=puncture%20aspiration%20irrigation%20reaspiration%20%28PAIR%29" title=" puncture aspiration irrigation reaspiration (PAIR)"> puncture aspiration irrigation reaspiration (PAIR)</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=hydatid%20disease" title=" hydatid disease"> hydatid disease</a> </p> <a href="https://publications.waset.org/abstracts/62441/experience-of-hydatid-disease-of-liver-at-a-tertiary-care-center-7-years-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62441.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">266</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">412</span> Generalized Up-downlink Transmission using Black-White Hole Entanglement Generated by Two-level System Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arif%20Jalil">Muhammad Arif Jalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Xaythavay%20Luangvilay"> Xaythavay Luangvilay</a>, <a href="https://publications.waset.org/abstracts/search?q=Montree%20Bunruangses"> Montree Bunruangses</a>, <a href="https://publications.waset.org/abstracts/search?q=Somchat%20Sonasang"> Somchat Sonasang</a>, <a href="https://publications.waset.org/abstracts/search?q=Preecha%20Yupapin"> Preecha Yupapin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Black and white holes form the entangled pair⟨BH│WH⟩, where a white hole occurs when the particle moves at the same speed as light. The entangled black-white hole pair is at the center with the radian between the gap. When the speed of particle motion is slower than light, the black hole is gravitational (positive gravity), where the white hole is smaller than the black hole. On the downstream side, the entangled pair appears to have a black hole outside the gap increases until the white holes disappear, which is the emptiness paradox. On the upstream side, when moving faster than light, white holes form times tunnels, with black holes becoming smaller. It will continue to move faster and further when the black hole disappears and becomes a wormhole (Singularity) that is only a white hole in emptiness (Emptiness). This research studies use of black and white holes generated by a two-level circuit for communication transmission carriers, in which high ability and capacity of data transmission can be obtained. The black and white hole pair can be generated by the two-level system circuit when the speech of a particle on the circuit is equal to the speed of light. The black hole forms when the particle speed has increased from slower to equal to the light speed, while the white hole is established when the particle comes down faster than light. They are bound by the entangled pair, signal and idler, ⟨Signal│Idler⟩, and the virtual ones for the white hole, which has an angular displacement of half of π radian. A two-level system is made from an electronic circuit to create black and white holes bound by the entangled bits that are immune or cloning-free from thieves. Start by creating a wave-particle behavior when its speed is equal to light black hole is in the middle of the entangled pair, which is the two bit gate. The required information can be input into the system and wrapped by the black hole carrier. A timeline (Tunnel) occurs when the wave-particle speed is faster than light, from which the entangle pair is collapsed. The transmitted information is safely in the time tunnel. The required time and space can be modulated via the input for the downlink operation. The downlink is established when the particle speed is given by a frequency(energy) form is down and entered into the entangled gap, where this time the white hole is established. The information with the required destination is wrapped by the white hole and retrieved by the clients at the destination. The black and white holes are disappeared, and the information can be recovered and used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloning%20free" title="cloning free">cloning free</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20machine" title=" time machine"> time machine</a>, <a href="https://publications.waset.org/abstracts/search?q=teleportation" title=" teleportation"> teleportation</a>, <a href="https://publications.waset.org/abstracts/search?q=two-level%20system" title=" two-level system"> two-level system</a> </p> <a href="https://publications.waset.org/abstracts/176235/generalized-up-downlink-transmission-using-black-white-hole-entanglement-generated-by-two-level-system-circuit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176235.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">411</span> Weak Convergence of Mann Iteration for a Hybrid Pair of Mappings in a Banach Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alemayehu%20Geremew%20Geremew">Alemayehu Geremew Geremew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We prove the weak convergence of Mann iteration for a hybrid pair of maps to a common fixed point of a selfmap f and a multivalued f nonexpansive mapping T in Banach space E. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=common%20fixed%20point" title="common fixed point">common fixed point</a>, <a href="https://publications.waset.org/abstracts/search?q=Mann%20iteration" title=" Mann iteration"> Mann iteration</a>, <a href="https://publications.waset.org/abstracts/search?q=multivalued%20mapping" title=" multivalued mapping"> multivalued mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=weak%20convergence" title=" weak convergence"> weak convergence</a> </p> <a href="https://publications.waset.org/abstracts/5913/weak-convergence-of-mann-iteration-for-a-hybrid-pair-of-mappings-in-a-banach-space" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5913.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">335</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">410</span> Bending Effect on POF Splitter Performance for Different Thickness of Fiber Cores</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20S.%20Supian">L.

The FEA can provide theoretical basis for the 3D model of controlling the strip shape and profile in thin strip rolling, and deliver an optimal rolling process parameter, and suggest corrective changes during cold rolling of thin strip. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pair%20roll%20crossing" title="pair roll crossing">pair roll crossing</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20roll%20shifting" title=" work roll shifting"> work roll shifting</a>, <a href="https://publications.waset.org/abstracts/search?q=strip%20shape%20and%20profile" title=" strip shape and profile"> strip shape and profile</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a> </p> <a href="https://publications.waset.org/abstracts/166979/advanced-approach-to-analysis-the-thin-strip-profile-in-cold-rolling-of-pair-roll-crossing-and-shifting-mill-using-an-arbitrary-lagrangian-eulerian-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166979.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">407</span> Studies on the Feasibility of Cow Dung as a Non-Conventional Energy Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Rajak">Raj Kumar Rajak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Mishra"> Bharat Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-batteries represent an entirely new long-term, reasonable, reachable and ecofriendly approach to produce sustainable energy. In the present experimental work, we have studied the effect of generation of power by bio-battery using different electrode pairs. The tests show that it is possible to generate electricity using cow dung as an electrolyte. C-Mg electrode pair shows maximum voltage and SCC (Short Circuit Current) while C-Zn electrode pair shows less OCV (Open Circuit Voltage) and SCC. We have chosen C-Zn electrodes because Mg electrodes are not economical. By the studies of different electrodes and cow dung, it is found that C-Zn electrode battery is more suitable. This result shows that the bio-batteries have the potency to full fill the need of electricity demand for lower energy equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-batteries" title="bio-batteries">bio-batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity" title=" electricity"> electricity</a>, <a href="https://publications.waset.org/abstracts/search?q=cow-dung" title=" cow-dung"> cow-dung</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodes" title=" electrodes"> electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=non-conventional" title=" non-conventional"> non-conventional</a> </p> <a href="https://publications.waset.org/abstracts/82579/studies-on-the-feasibility-of-cow-dung-as-a-non-conventional-energy-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82579.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">205</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">406</span> Studies on the Feasibility of Cow’s Urine as Non-Conventional Energy Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Rajak">Raj Kumar Rajak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Mishra"> Bharat Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-batteries represent an entirely new long-term, reasonable, reachable, and eco-friendly approach to generation of sustainable energy.
