However, local susceptibility variations can lead to field inhomogeneities that cause artifacts such as image distortion and signal loss. The effects of local susceptibility variation notoriously increase with magnetic field strength. Active shimming improves homogeneity by applying corrective fields generated from shim coils, but requires calculation of optimal current for each shim coil. FASTMAP (fast automatic shimming technique by mapping along projections) is an effective technique for finding optimal currents works well at high-field, but is restricted to shimming spherical regions of interest. The 3D gradient-echo pulse sequence was modified to reduce sensitivity to eddy currents and used to obtain susceptibility field maps at 4T. Measured fields were projected onto first-and second-order spherical harmonic functions corresponding to shim hardware. A spherical phantom was used to calibrate the shim currents. Susceptibility maps of a volunteer’s brain with and without FASTMAP shimming were obtained. Simulations indicate that optimal shim currents derived from the field map may provide better overall shimming of the human brain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shimming" title="shimming">shimming</a>, <a href="https://publications.waset.org/abstracts/search?q=high-field" title=" high-field"> high-field</a>, <a href="https://publications.waset.org/abstracts/search?q=active" title=" active"> active</a>, <a href="https://publications.waset.org/abstracts/search?q=passive" title=" passive"> passive</a> </p> <a href="https://publications.waset.org/abstracts/33673/comparison-of-fastmap-and-b0-field-map-shimming-for-4t-mri" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33673.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">509</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">10739</span> Conceptual Model for Massive Open Online Blended Courses Based on Disciplines’ Concepts Capitalization and Obstacles’ Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Hammid">N.

Apart from the current MOOCs design and purposes, the creators of MOOC focused on the importance of the connection and knowledge exchange between individuals in learning. In this paper, we present a conceptual model for massive open online blended courses where teachers over the world can collaborate and exchange their experience to get a common efficient content designed as a MOOC opened to their students to live a better learning experience. This model is based on disciplines’ concepts capitalization and the detection of the obstacles met by their students when faced with problem situations (exercises, projects, case studies, etc.). This detection is possible by analyzing the frequently of semantic errors committed by the students. The participation of teachers in the design of the course and the attendance by their students can guarantee an efficient and extensive participation (an important number of participants) in the course, the learners’ motivation and the evaluation issues, in the way that the teachers designing the course assess their students. Thus, the teachers review, together with their knowledge, offer a better assessment and efficient connections to their students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=massive%20open%20online%20course" title="massive open online course">massive open online course</a>, <a href="https://publications.waset.org/abstracts/search?q=MOOC" title=" MOOC"> MOOC</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a> </p> <a href="https://publications.waset.org/abstracts/59661/conceptual-model-for-massive-open-online-blended-courses-based-on-disciplines-concepts-capitalization-and-obstacles-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59661.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">268</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">10738</span> An Investigation on Electric Field Distribution around 380 kV Transmission Line for Various Pylon Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20F.%20Kumru">C.

Analyses are performed in both stationary and time domains to observe instantaneous values along with the effective ones. Considering the results of the study, different line geometries is considerably affecting the magnitude and distribution of electric field although the line voltages are the same. Furthermore, it is observed that maximum values of instantaneous electric field obtained in time domain analysis are quite higher than the effective ones in stationary mode. In consequence, electric field distribution analyses should be individually made for each different line model and the limit exposure values or distances to residential buildings should be defined according to the results obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20field" title="electric field">electric field</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20transmission%20line" title=" energy transmission line"> energy transmission line</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=pylon" title=" pylon"> pylon</a> </p> <a href="https://publications.waset.org/abstracts/29819/an-investigation-on-electric-field-distribution-around-380-kv-transmission-line-for-various-pylon-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29819.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">728</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">10737</span> In the Spirit of Open Educational Resources: Library Resources and Fashion Merchandising</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lizhu%20Y.%20Davis">Lizhu Y.

But this leads to a dead end in traditional physics, and quantum explanations must be referred to explain the magnetic phenomenon. However, a study of magnetic lines as percussive waves leads to other paths capable of interpreting magnetism through traditional physics. Methodology: Brick used in the experiment: two parallel electric current cables attract each other if current goes in the same direction and its application at a microscopic level inside magnets. Significance: Consideration of magnetic lines as magnets themselves would mean a paradigm shift in the study of magnetism and open the way to provide solutions to mysteries of magnetism until now only revealed by quantum mechanics. Major findings: discover how a magnetic field is created, as well as reason how magnetic attraction and repulsion work, understand how magnets behave when splitting them, and reveal the impossibility of a Magnetic Monopole. All of this is presented as if it were a symphony in which all the notes fit together perfectly to create a beautiful, smart, and simple work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20lines%20of%20force" title="magnetic lines of force">magnetic lines of force</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20attraction%20and%20repulsion" title=" magnetic attraction and repulsion"> magnetic attraction and repulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=magnet%20split" title=" magnet split"> magnet split</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20monopole" title=" magnetic monopole"> magnetic monopole</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20lines%20of%20force%20as%20magnets" title=" magnetic lines of force as magnets"> magnetic lines of force as magnets</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20lines%20of%20force%20as%20waves" title=" magnetic lines of force as waves"> magnetic lines of force as waves</a> </p> <a href="https://publications.waset.org/abstracts/172916/consideration-of-magnetic-lines-of-force-as-magnets-produced-by-percussion-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172916.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">90</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">10735</span> Experimental Investigation with Different Inclination Angles on Copper Oscillating Heat Pipes Performance Using Fe2O3 / Kerosene under Magnetic Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20R.%20Goshayeshi">H.

However, growing health challenges in a city would raise attention to the planning quality of these community's assets. This research aims to measure the existing availability and distribution equity of POS in the context of Saudi Arabia using Riyadh city as a case study. The methodology for the POS availability was by calculating the total POS with respect to the population total (m²/inhabitant). All POS were mapped using geographical information systems (GIS), and the total area availability of POS was compared to global, regional, and local standards. To evaluate the significant differences in POS availability across low, medium, and high-income Riyadh neighborhoods, we used a One-way ANOVA analysis of covariance to test the differences. The results are as follows; POS availability was lower than global standers. Riyadh has only 1.40m² per capita of POS.

The sharp drive to uncover the secrets of stars and their unusual deportment was dependably an ignitor of stars investigation. As humankind lives in civilizations and states, stars likewise live in provinces named ‘clusters’. Clusters are separates into 2 composes i.e. open clusters and globular clusters. An open cluster is a gathering of thousand stars that were moulded from a comparable goliath sub-nuclear cloud and for the most part; contain Propulsion I (extremely metal-rich) and Propulsion II (mild metal-rich), where globular clusters are around gathering of more than thirty thousand stars that circles a galactic focus and basically contain Propulsion III (to a great degree metal-poor) stars. Futurology of this paper lies in the spectroscopic investigation of globular clusters like M92 and NGC419 and open clusters like M34 and IC2391 in different color bands by using software like VIREO virtual observatory, Aladin, CMUNIWIN, and MS-Excel. Assessing the outcome Hertzsprung-Russel (HR) diagram with exemplary cosmological models like Einstein model, De Sitter and Planck survey demonstrate for a superior age estimation of respective clusters.

For instance at the Trinity (Union) Theological College, Umuahia, it was difficult for lecturers to access suitable and qualitative materials for instruction especially the ones that would suit the African context and stimulate a deep rooted interest among the students. Some textbooks written by foreign authors were readily available in the School Library, but were lacking in the College bookshops for students to own copies. Even when the College was able to order some of the books from abroad, it did not usher in the needed enthusiasm expected from the students because they were either very expensive or very difficult to understand during private studies. So it became necessary to develop contextual materials which were affordable and understandable, though with little success. The National Open University of Nigeria (NOUN)’s innovation in the development and sharing of learning resources through its Open Course ware is a welcome development and of great assistance to students. Apart from NOUN students who could easily access the materials, many others from various theological/religious institutes across the nation have benefited immensely. So, the thesis of this paper is that the promotion of open educational resources in theological/religious education in Nigeria would facilitate a better informed/equipped religious leadership, which would in turn impact its adherents for a healthier society and national development. Adopting a narrative and historical approach within the context of Nigeria’s educational system, the paper discusses: educational traditions in Nigeria; challenges facing theological/religious education in Nigeria; and benefits of open educational resources. The study goes further to making recommendations on how OER could positively influence theological/religious education in Nigeria. It is expected that theologians, religious educators, and ODL practitioners would find this work very useful. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OER" title="OER">OER</a>, <a href="https://publications.waset.org/abstracts/search?q=theological%20education" title=" theological education"> theological education</a>, <a href="https://publications.waset.org/abstracts/search?q=religious%20education" title=" religious education"> religious education</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/13561/promoting-open-educational-resources-oer-in-theologicalreligious-education-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13561.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">346</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">10728</span> The Preliminary Study of the Possible Relationship between Urban Open Space System and Residents' Health Outcome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jia-Jin%20He">Jia-Jin He</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Yuan%20Stessa%20Chao"> Tzu-Yuan Stessa Chao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is generally accepted that community residents with abundant open space have better health status on average, and thus more and more cities around the world began their pursuit of the greatest possible amount of green space within urban areas through urban planning approach. Nevertheless, only a few studies managed to provide empirical evidence regarding the actual relationship between 'providing' green space and 'improving' human health at city level. There is also lack of evidence of direct positive improvement of health by increasing the amount of green space. For urban planning professional, it is important to understand citizens’ usage behaviour towards green space as a critical evidence for future planning and design strategies. There is a research need to further investigate the amount of green space, user behaviour of green spaces and the health outcome of urban dwellers. To this end, we would like to find out other important factors for urban dwellers’ usage behaviours of green spaces. 'Average green spaces per person' is one of the National well-being Indicators in Taiwan as in many other countries. Through our preliminary research, we collected and analyzed the official data of planned open space coverages, average life expectancy, exercise frequency and obesity ratio in all cities of Taiwan. The study result indicates an interesting finding that Kaohsiung city, the second largest city in Taiwan, tells a completely different story. Citizens in Kaosiung city have more open spaces than any other city through urban planning, yet have relatively unhealthy condition in contrary. Whether it pointed out that the amount of the open spaces per person has would not direct to the health outcome. Therefore, the pre-established view which states that open spaces must have positive effects on human health should be examined more prudently. Hence, this paper intends to explore the relationship between user behaviour of open spaces and citizens’ health conditions by critically analyzing past related literature and collecting selective data from government health database in 2015. We also take Kaohsiung city, as a case study area to conduct statistical analysis first followed by questionnaire survey to gain a better understanding. Finally, we aim to feedback our findings to the current planning system in Taiwan for better health promotion urbanized areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20spaces" title="open spaces">open spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20planning%20systems" title=" urban planning systems"> urban planning systems</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20cities" title=" healthy cities"> healthy cities</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20outcomes" title=" health outcomes"> health outcomes</a> </p> <a href="https://publications.waset.org/abstracts/84111/the-preliminary-study-of-the-possible-relationship-between-urban-open-space-system-and-residents-health-outcome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84111.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">165</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">10727</span> The Impact of Built Environment Design on Users’ Psychology to Foster Pro-Environmental Behavior in University Open Spaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rehab%20Mahmoud%20El%20Sayed">Rehab Mahmoud El Sayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Toka%20Fahmy%20Nasr"> Toka Fahmy Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalia%20M.%20Rasmi"> Dalia M.

This field is crucial in understanding how the built environment affects human behaviour, moods and feelings. Studying and understanding the aspects and influences of environmental psychology is a crucial key to investigating how the design can influence human behaviour to be environmentally friendly. This is known as pro-environmental behaviour where human actions are sustainable and impacts the environment positively. Accordingly, this paper aims to explore the impact of built environment design on environmental psychology to foster pro-environmental behaviour in university campus open spaces. In order to achieve this, an exploratory research method was conducted where a detailed study of the influences of environmental psychology was done and clarified its elements. Moreover, investigating the impact of design elements on human psychology took place. Besides, an empirical study of the outdoor spaces of the British University in Egypt occurred and a survey for students and staff was distributed. The research concluded that the four main psychological aspects are mostly influenced by the following design elements colours, lighting and thermal comfort respectively. Additionally, focusing on these design elements in the design process will create a sustainable environment. As a consequence, the pro-environmental behaviour of the user will be fostered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20psychology" title="environmental psychology">environmental psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=pro-environmental%20behavior" title=" pro-environmental behavior"> pro-environmental behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20environment" title=" sustainable environment"> sustainable environment</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20influences" title=" psychological influences"> psychological influences</a> </p> <a href="https://publications.waset.org/abstracts/166632/the-impact-of-built-environment-design-on-users-psychology-to-foster-pro-environmental-behavior-in-university-open-spaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166632.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">84</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">10726</span> Three-dimensional Steady Flow in Thin Annular Pools of Silicon Melt under a Magnetic Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Mahfoud">Brahim Mahfoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A three-dimensional (3D) numerical technique is used to investigate the possibility of reducing the price of manufacturing some silicon-based devices, particularly those in which minor temperature gradients can significantly reduce performance. The silicon melt under the magnetic field produces Lorentz force, which can effectively suppress the flow which is caused by temperature gradients. This might allow some silicon-based products, such as solar cells, to be manufactured using a less pure, and hence less expensive. The thermocapillary effect of the silicon melt flow in thin annular pools subjected to an externally induced magnetic field was observed. The results reveal that with a strong enough magnetic field, isothermal lines change form and become concentric circles. As the amplitude of the magnetic field (Ha) grows, the azimuthal velocity and temperature at the free surface reduce, and the asymmetric 3D flow becomes axisymmetric steady when Ha surpasses a threshold value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title="magnetic field">magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20melt" title=" silicon melt"> silicon melt</a>, <a href="https://publications.waset.org/abstracts/search?q=thermocapillary" title=" thermocapillary"> thermocapillary</a> </p> <a href="https://publications.waset.org/abstracts/174986/three-dimensional-steady-flow-in-thin-annular-pools-of-silicon-melt-under-a-magnetic-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174986.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">84</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">10725</span> The First Trocar Placement After Multiple Open Abdominal Surgeries in Children: A Preliminary Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96yk%C3%BC%20Barut%C3%A7u">Öykü Barutçu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20%C3%96zg%C3%BCr%20Kuzdan"> Mehmet Özgür Kuzdan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Laparoscopy is very risky in patients undergoing, multiple open abdominal surgeries. The aim of this study, to define a safe method for the first trocar placement in children with a history of multiple open abdominal surgeries. Methods: Children who underwent laparoscopic surgery between March 2019 and April 2020 with a history of three or more open abdominal surgeries were included in the retrospective study. Patient information was obtained from the hospital automation system. Ultrasonography was used to determine the location of adhesions preoperatively. The first trocar was placed according to ultrasonography findings, using the Hasson technique to create an air pocket with finger dissection. The patient's preoperative, perioperative, and postoperative findings are reported. Results: A total of 10 patients were included in the study. The median number of operations before laparoscopy was three. The most common site for the first trocar entry was Palmer's point (40%). No mortality or morbidity was observed amongst any patients. The average number of adhesions detected by USG and observed on laparoscopy were significantly positively correlated. Conclusion: In children with a history of multiple abdominal surgeries, abdominal wall ultrasonography for visualization of adhesions and finger dissection for the formation of an air pocket appears to be a safe method for the first trocar insertion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abdominal%20wall" title="abdominal wall">abdominal wall</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a>, <a href="https://publications.waset.org/abstracts/search?q=laparoscopy" title=" laparoscopy"> laparoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonography" title=" ultrasonography"> ultrasonography</a> </p> <a href="https://publications.waset.org/abstracts/153771/the-first-trocar-placement-after-multiple-open-abdominal-surgeries-in-children-a-preliminary-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10724</span> Classroom Readiness of Open and Distance Learning Student Teachers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20C.%20du%20Plessis">E.

Pomel is a root holoparasitic weed plant of many cultivations, particularly of tomato (<em>Lycopersicum esculentum</em> L.) crop. In Italy, <em>Phelipanche</em> problem is increasing, both in density and in acreage. The biological control of this parasitic weed involves the use of living organisms as numerous fungi and bacteria that can infect the parasitic weed, while it may improve the crop growth. This paper deals with the biocontrol with microorganism, including Arbuscular mycorrhizal (AM) fungi and fungal pathogens as<em> Fusarium oxisporum </em>spp. Colonization of crop roots by AM fungi can provide protection of crops against parasitic weeds because of a reduction in their seed germination and attachment, while <em>F. oxisporum</em>, isolated from diseased broomrape tubercles, proved to be highly virulent on <em>P. ramosa</em>. The experimental trial was carried out in open field at Foggia province (Apulia Region, Southern Italy), during the spring-summer season 2016, in order to evaluate the effect of four biological treatments: AM fungi and <em>Fusarium oxisporum </em>applied in the soil alone or combined together, and Rizosum Max<sup>®</sup> product, compared with the untreated control, to reduce the<em> P. ramosa</em> infestation in processing tomato crop. The principal results to be drawn from this study under field condition, in contrast of those reported previously under laboratory and greenhouse conditions, show that both AM fungi and <em>F. oxisporum</em> do not provide the reduction of the number of emerged shoots of <em>P. ramosa.</em> This can arise probably from the low efficacy seedling of the agent pathogens for the control of this parasite in the field<em>. </em>On the contrary, the Rizosum Max<sup>®</sup> product, containing AM fungi and some rizophere bacteria combined with several minerals and organic substances, appears to be most effective for the reduction of <em>P. ramosa</em> infestation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arbuscular%20mycorrhized%20fungi" title="Arbuscular mycorrhized fungi">Arbuscular mycorrhized fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=biocontrol%20methods" title=" biocontrol methods"> biocontrol methods</a>, <a href="https://publications.waset.org/abstracts/search?q=Phelipanche%20ramosa" title=" Phelipanche ramosa"> Phelipanche ramosa</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20crop" title=" tomato crop"> tomato crop</a> </p> <a href="https://publications.waset.org/abstracts/63729/biological-methods-to-control-parasitic-weed-phelipanche-ramosa-l-pomel-in-the-field-tomato-crop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63729.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">462</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">10722</span> Performance of Different Spray Nozzles in the Application of Defoliant on Cotton Plants (Gossypium hirsutum L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamud%20Ali%20Ibrahim">Mohamud Ali Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bayat"> Ali Bayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bolat"> Ali Bolat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Defoliant spraying is an important link in the mechanized cotton harvest because adequate and uniform spraying can improve defoliation quality and reduce cotton trash content. In defoliant application, application volume and spraying technology are extremely important. In this study, the effectiveness of defoliant application to cotton plant that has come to harvest with two different application volumes and three different types of nozzles with a standard field crop sprayer was determined. Experiments were carried in two phases as field area trials and laboratory analysis. Application rates were 250 l/ha and 400 L/ha, and spraying nozzles were (1) Standard flat fan nozzle (TP8006), (2) Air induction nozzle (AI 11002-VS), and (3) Dual Pattern nozzle (AI307003VP). A tracer (BSF) and defoliant were applied to mature cotton with approximately 60% open bolls and samplings for BSF deposition and spray coverage on the cotton plant were done at two plant height (upper layer, lower layer) of plant. Before and after spraying, bolls open and leaves rate on cotton plants were calculated, and filter papers were used to detect BSF deposition, and water sensitive papers (WSP) were used to measure the coverage rate of spraying methods used. Spectrofluorophotometer was used to detect the amount of tracer deposition on targets, and an image process computer programme was used to measure coverage rate on WSP. In analysis, conclusions showed that air induction nozzle (AI 11002-VS) achieved better results than the dual pattern and standard flat fan nozzles in terms of higher depositions, coverages, and leaf defoliations, and boll opening rates. AI nozzles operating at 250 L/ha application rate provide the highest deposition and coverage rate on applications of the defoliant; in addition, BSF as an indicator of the defoliant used reached on leaf beneath in merely this spray nozzle. After defoliation boll opening rate was 85% on the 7th and 12th days after spraying and falling rate of leaves was 76% at application rate of 250 L/ha with air induction (AI1102) nozzle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cotton%20defoliant" title="cotton defoliant">cotton defoliant</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20induction%20nozzle" title=" air induction nozzle"> air induction nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20pattern%20nozzle" title=" dual pattern nozzle"> dual pattern nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20flat%20fan%20nozzle" title=" standard flat fan nozzle"> standard flat fan nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=coverage%20rate" title=" coverage rate"> coverage rate</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20deposition" title=" spray deposition"> spray deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=boll%20opening%20rate" title=" boll opening rate"> boll opening rate</a>, <a href="https://publications.waset.org/abstracts/search?q=leaves%20falling%20rate" title=" leaves falling rate"> leaves falling rate</a> </p> <a href="https://publications.waset.org/abstracts/141813/performance-of-different-spray-nozzles-in-the-application-of-defoliant-on-cotton-plants-gossypium-hirsutum-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141813.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">197</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">10721</span> Toward Subtle Change Detection and Quantification in Magnetic Resonance Neuroimaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Esmaeilpour">Mohammad Esmaeilpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the important open problems in the field of medical image processing is detection and quantification of small changes.

The introduction of robotic solutions in this field is an increasingly researched topic to make the most of the Earth's resources, thus going to avoid the problems of wear and tear of the human body due to the harsh agricultural work, and open the possibility of a constant careful processing 24 hours a day. This project is realized for a terrestrial autonomous robot aimed to navigate in an orchard collecting fallen peaches below the trees. When it receives the signal indicating the low battery, it has to return to the docking station where it will replace its battery and then return to the last work point and resume its routine. Considering a preset path in orchards with tree rows with variable length by which the robot goes iteratively using the algorithm D*. In case of low battery, the D* algorithm is still used to determine the fastest return path to the docking station as well as to come back from the docking station to the last work point. MATLAB simulations were performed to analyze the flexibility and adaptability of the developed algorithm. The simulation results show an enormous potential for adaptability, particularly in view of the irregularity of orchard field, since it is not flat and undergoes modifications over time from fallen branch as well as from other obstacles and constraints. The D* algorithm determines the best route in spite of the irregularity of the terrain. Moreover, in this work, it will be shown a possible solution to improve the initial points tracking and reduce time between movements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=path%20planning" title="path planning">path planning</a>, <a href="https://publications.waset.org/abstracts/search?q=fastest%20return%20path" title=" fastest return path"> fastest return path</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20autonomous%20terrestrial%20robot" title=" agricultural autonomous terrestrial robot"> agricultural autonomous terrestrial robot</a>, <a href="https://publications.waset.org/abstracts/search?q=docking%20station" title=" docking station"> docking station</a> </p> <a href="https://publications.waset.org/abstracts/96930/fast-return-path-planning-for-agricultural-autonomous-terrestrial-robot-in-a-known-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96930.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">134</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">10719</span> Videoconference Technology: An Attractive Vehicle for Challenging and Changing Tutors Practice in Open and Distance Learning Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramorola%20Mmankoko%20Ziphorah">Ramorola Mmankoko Ziphorah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Videoconference technology represents a recent experiment of technology integration into teaching and learning in South Africa. Increasingly, videoconference technology is commonly used as a substitute for the traditional face-to-face approaches to teaching and learning in helping tutors to reshape and change their teaching practices. Interestingly, though, some studies point out that videoconference technology is commonly used for knowledge dissemination by tutors and not so much for the actual teaching of course content in Open and Distance Learning context. Though videoconference technology has become one of the dominating technologies available among Open and Distance Learning institutions, it is not clear that it has been used as effectively to bridge the learning distance in time, geography, and economy. While tutors are prepared theoretically, in most tutor preparation programs, on the use of videoconference technology, there are still no practical guidelines on how they should go about integrating this technology into their course teaching. Therefore, there is an urgent need to focus on tutor development, specifically on their capacities and skills to use videoconference technology. The assumption is that if tutors become competent in the use of the videoconference technology for course teaching, then their use in Open and Distance Learning environment will become more commonplace. This is the imperative of the 4th Industrial Revolution (4IR) on education generally. Against the current vacuum in the practice of using videoconference technology for course teaching, the current study proposes a qualitative phenomenological approach to investigate the efficacy of videoconferencing as an approach to student learning. Using interviews and observation data from ten participants in Open and Distance Learning institution, the author discusses how dialogue and structure interacted to provide the participating tutors with a rich set of opportunities to deliver course content. The findings to this study highlight various challenges experienced by tutors when using videoconference technology. The study suggests tutor development programs on their capacity and skills and on how to integrate this technology with various teaching strategies in order to enhance student learning. The author argues that it is not merely the existence of the structure, namely the videoconference technology, that provides the opportunity for effective teaching, but that is the interactions, namely, the dialogue amongst tutors and learners that make videoconference technology an attractive vehicle for challenging and changing tutors practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20distance%20learning" title="open distance learning">open distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=transactional%20distance" title=" transactional distance"> transactional distance</a>, <a href="https://publications.waset.org/abstracts/search?q=tutor" title=" tutor"> tutor</a>, <a href="https://publications.waset.org/abstracts/search?q=videoconference" title=" videoconference"> videoconference</a> </p> <a href="https://publications.waset.org/abstracts/147474/videoconference-technology-an-attractive-vehicle-for-challenging-and-changing-tutors-practice-in-open-and-distance-learning-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147474.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">128</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">10718</span> Flexible Furniture in Urban Open Spaces: A Tool to Achieve Social Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Ghafouri">Mahsa Ghafouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Guita%20Farivarsadri"> Guita Farivarsadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In urban open spaces, furniture plays a crucial role in meeting various needs of the users over time. Furniture consists of elements that not only can facilitate physical needs individually but also fulfill social, psychological, and cultural demands on an urban scale. Creating adjustable urban spaces and using flexible furniture can provide the possibility of using urban spaces for a wide range of uses and activities and allow the engagement of users with distinct abilities and limitations in these activities. Flexibility in urban furniture can be seen as designing a number of modular components that are movable, expandable, adjustable, and changeable to accommodate various functions. Although there is a great amount of research related to flexibility and its distinct insights into achieving spaces that can cope with changing demands, this fundamental issue is often neglected in the design of urban furniture. However, in the long term, to address changing public needs over time, it can be logical to bring this quality into the design process to make spaces that can be sustained for a long time. This study aims to first introduce diverse kinds of flexible furniture that can be designed for urban public spaces and then to realize how this flexible furniture can improve the quality of public open spaces and social interaction and make them more adaptable over time and, as a result, achieve social sustainability. This research is descriptive and is mainly based on an extensive literature review and the analysis and classification of existing examples around the world. This research tends to illustrate various kinds of approaches that can help designers create flexible furniture to enhance the sustainability and quality of urban open spaces and, in this way, act as a guide for urban designers in this respect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20furniture" title="flexible furniture">flexible furniture</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20design" title=" flexible design"> flexible design</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20open%20spaces" title=" urban open spaces"> urban open spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptability" title=" adaptability"> adaptability</a>, <a href="https://publications.waset.org/abstracts/search?q=moveability" title=" moveability"> moveability</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sustainability" title=" social sustainability"> social sustainability</a> </p> <a href="https://publications.waset.org/abstracts/181521/flexible-furniture-in-urban-open-spaces-a-tool-to-achieve-social-sustainability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181521.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">59</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">10717</span> Assessment of E-learning Facilities and Information Need by Open and Distance Learning Students in Jalingo, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20M.%20Bashir">R.

An investigation on the assessment of e-learning facilities and information need by open and distance learning students in Jalingo, Nigeria was conducted. Structured questionnaires were administered to 70 students of the university. Information sourced from the respondents covered demographic, economic and institutional variables. Data collected for demographic variables were computed as frequency count and percentages. Information on assessment of e-learning facilities and information need among open and distance learning students was computed on a three or four point Likert Rating Scale. Findings indicated that there are more men compared to women, a large proportion of the respondents are married and there are more matured students. A high proportion of the students obtained qualifications higher than the secondary school certificate. The proportion of computer literate students was higher compared with those students that owned a computer. Inadequate e-books and reference materials, internet gadgets and inadequate books (hard copies) and reference material are factors that limit utilization of e-learning facilities. Inadequate computer facilities caused delay in examination schedule at the study center. Open and distance learning students required to a high extent information on university timetable and schedule of activities, books (hard and e-books) and reference materials and contact with course coordinators via internet for better learning and academic performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20and%20distance%20learning" title="open and distance learning">open and distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20required" title=" information required"> information required</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20books" title=" electronic books"> electronic books</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20gadgets" title=" internet gadgets"> internet gadgets</a>, <a href="https://publications.waset.org/abstracts/search?q=Likert%20scale%20test" title=" Likert scale test"> Likert scale test</a> </p> <a href="https://publications.waset.org/abstracts/5786/assessment-of-e-learning-facilities-and-information-need-by-open-and-distance-learning-students-in-jalingo-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5786.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">286</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">10716</span> Inverter IGBT Open–Circuit Fault Detection Using Park's Vectors Enhanced by Polar Coordinates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bendiabdellah%20Azzeddine">Bendiabdellah Azzeddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Cherif%20Bilal%20Djamal%20Eddine"> Cherif Bilal Djamal Eddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The three-phase power converter voltage structure is widely used in many power applications but its failure can lead to partial or total loss of control of the phase currents and can cause serious system malfunctions or even a complete system shutdown.

However, food availability, particularly rice, is limited. Impacts of rice-field conversion have run cumulatively, as we can see on potential losses of rice and crops production, as well as work opportunity that keeps increasing year-by-year. Therefore, it requires policy recommendation to control rice-field conversion through economic, social, and ecological approaches. The research was a survey method intended to: (1) Identify internal factors; quality and productivity of the land as the cause of land conversion, (2) Identify external factors of land conversion, value of the rice-field and the competitor’s land, workforce absorption, and regulation, as well as (3) Formulate strategies in controlling rice-field conversion. Population of the research was farmers who applied land conversion at Pangkep Regency, South Sulawesi. Samples were determined using the incidental sampling method. Data analysis used productivity analysis, land quality analysis, total economic value analysis, and SWOT analysis. Results of the research showed that the quality of rice-field was low as well as productivity of the grains (unhulled-rice). So that, average productivity of the grains and quality of rice-field were low as well. Total economic value of rice-field was lower than the economic value of the embankment. Workforce absorption value on rice-field was higher than on the embankment. Strategies in controlling such rice-field conversion can be done by increasing rice-field productivity, improving land quality, applying cultivation technique of specific location, improving the irrigation lines, and socializing regulation and sanction about the transfer of land use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20conversion" title="land conversion">land conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20rice-field" title=" quality of rice-field"> quality of rice-field</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20economic%20value." title=" land economic value."> land economic value.</a> </p> <a href="https://publications.waset.org/abstracts/56534/strategy-in-controlling-rice-field-conversion-in-pangkep-regency-south-sulawesi-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56534.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">275</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">10714</span> Green Public Procurement in Open Access and Traditional Journals: A Comparative Bibliometric Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alonso-Ca%C3%B1adas%20J.">Alonso-Cañadas J.</a>, <a href="https://publications.waset.org/abstracts/search?q=Gal%C3%A1n-Valdivieso%20F."> Galán-Valdivieso F.</a>, <a href="https://publications.waset.org/abstracts/search?q=Saraite-Sariene%20L."> Saraite-Sariene L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Garc%C3%ADa-Tabuyo%20M."> García-Tabuyo M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Alonso-Morales%20N."> Alonso-Morales N.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green Public Procurement (GPP) has recently gained attention in the academic and policy arenas since climate change has shown the need to be addressed by both private companies and public entities. Such growing interest motivates this article, aiming to explore the most influential journals, publishers, categories, and topics, as well as the recent trends and future research lines in GPP. Based on the Web of Science database, 578 articles from 2004 to February 2022 devoted to GPP are analyzed using Bibliometrix, an R-tool to perform bibliometric analysis, and Google’s Big Query and Data Studio. This article introduces a variety of findings. First, the most influential journals by far are “Journal of Cleaner Production” and “Sustainability,” differing in that the latter is open access while the former publishes via traditional subscription. This result also occurs regarding the main publishers (Elsevier and MDPI). These features lead us to split the sample into open-access journals and traditional journals to deepen into the similarities and differences between them, confirming that traditional journals exhibit a higher degree of influence in the literature than their open-access counterparts in terms of the number of documents, number of citations and impact (according to the H index). Second, this research also highlights the recent emergence of green-related terms (sustainable, environment) and, parallelly, the increase in categorizing GPP papers in “green” WoS categories, particularly since 2019. Finally, a number of related topics are emerging and will lead the research, such as food security, infrastructures, and implementation barriers of GPP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bibliometric%20analysis" title="bibliometric analysis">bibliometric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20public%20procurement" title=" green public procurement"> green public procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20access" title=" open access"> open access</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20journals" title=" traditional journals"> traditional journals</a> </p> <a href="https://publications.waset.org/abstracts/157465/green-public-procurement-in-open-access-and-traditional-journals-a-comparative-bibliometric-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157465.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">104</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">10713</span> Small-Sided Games in Football: Effect of Field Sizes on Technical Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faruk%20Guven">Faruk Guven</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurtekin%20Erkmen"> Nurtekin Erkmen</a>, <a href="https://publications.waset.org/abstracts/search?q=Samet%20Aktas"> Samet Aktas</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Taskin"> Cengiz Taskin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to determine effects of field sizes on technical parameters of small-sided games in football players. Eight amateur football players (27.23±3.08 years, heigth: 171.01±5.36 cm, body weigth: 66.86±4.54 kg, sports experience: 12.88±3.28 years) performed 4-a-side small-sided games (SSG) with different field sizes. In SSGs, field sizes were 30 x 40 m and 26 mx24 m. SSGs was conducted as a series of 3 bouts of 6 min with 5 min recovery durations. All SSGs were video recorded using two digital video camcorder positioned on a tripot. Shoot on taget, passes, succesful passes, unsuccesful passes, dripling, tackle, possession in SSGs were counted by Mathball Match Analysis System. The effects of bouts on technical score were examined separately using a Friedman’s test. Mann Whitney U test was applied to analyse differences between field sizes. There were no significant differences in shoots on target, total pass, successful pass, tackle, interception, possession between bouts in 30x40 m field size (p>0.05). Unsuccessful pass in bout 3 for 30x40 m field size was lower than bout 1 and bout 2 (p<0.05) and dripling in bout 3 was lower than bout 2 (p<0.05). There was no significant difference in technical actions between bouts for 26x34 m field size (p>0.05). Shoot on target in SSG with 26 x 34 m field size was higher than SSG with 30x40 m field size (p<0.05). Unsuccessful pass for 26x34 m field size in bout 3 was higher than SSG with 30x40 m field size (p<0.05). There was no significant difference in technical actions between field sizes (p>0.05). In conclusion; in this study demonstrates that technical actions in a-4-side SSG are not influenced by different field sizes (for 30x40 m and 26x34 m field sizes). This consequence is same for both total SSG time and each bout. Dripling and unsuccessful pass decrease in bout 3 during SSG in 30 x 40 m field size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small-sided%20games" title="small-sided games">small-sided games</a>, <a href="https://publications.waset.org/abstracts/search?q=football" title=" football"> football</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20actions" title=" technical actions"> technical actions</a>, <a href="https://publications.waset.org/abstracts/search?q=sport%20science" title=" sport science"> sport science</a> </p> <a href="https://publications.waset.org/abstracts/17946/small-sided-games-in-football-effect-of-field-sizes-on-technical-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17946.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">552</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">10712</span> An Intensional Conceptualization Model for Ontology-Based Semantic Integration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fateh%20Adhnouss">Fateh Adhnouss</a>, <a href="https://publications.waset.org/abstracts/search?q=Husam%20El-Asfour"> Husam El-Asfour</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenneth%20McIsaac"> Kenneth McIsaac</a>, <a href="https://publications.waset.org/abstracts/search?q=AbdulMutalib%20Wahaishi"> AbdulMutalib Wahaishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Idris%20El-Feghia"> Idris El-Feghia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conceptualization is an essential component of semantic ontology-based approaches. There have been several approaches that rely on extensional structure and extensional reduction structure in order to construct conceptualization. In this paper, several limitations are highlighted relating to their applicability to the construction of conceptualizations in dynamic and open environments. These limitations arise from a number of strong assumptions that do not apply to such environments. An intensional structure is strongly argued to be a natural and adequate modeling approach. This paper presents a conceptualization structure based on property relations and propositions theory (PRP) to the model ontology that is suitable for open environments. The model extends the First-Order Logic (FOL) notation and defines the formal representation that enables interoperability between software systems and supports semantic integration for software systems in open, dynamic environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptualization" title="conceptualization">conceptualization</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=extensional%20structure" title=" extensional structure"> extensional structure</a>, <a href="https://publications.waset.org/abstracts/search?q=intensional%20structure" title=" intensional structure"> intensional structure</a> </p> <a href="https://publications.waset.org/abstracts/151398/an-intensional-conceptualization-model-for-ontology-based-semantic-integration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151398.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">115</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">10711</span> Maresin Like 1 Treatment: Curbing the Pathogenesis of Behavioral Dysfunction and Neurodegeneration in Alzheimer's Disease Mouse Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yan%20Lu">Yan Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Hong"> Song Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Janakiraman%20Udaiyappan"> Janakiraman Udaiyappan</a>, <a href="https://publications.waset.org/abstracts/search?q=Aarti%20Nagayach"> Aarti Nagayach</a>, <a href="https://publications.waset.org/abstracts/search?q=Quoc-Viet%20A.%20Duong"> Quoc-Viet A.

This study aimed to investigate the effect of maresin like 1 (MaR-L1) treatment in AD pathology using 5XFAD mice. Methods: We tested 12-month-old male 5XFAD mice and wild type control mice treated with MaR-L1 in a battery of behavioral tasks. We performed open field test, beam walking test, clasping test, inverted grid test, acetone test, marble burring test, elevated plus maze test, cross maze test and novel object recognition test. We also studied neuronal loss, amyloid β burden, and inflammation in the brains of 5XFAD mice using immunohistology and Western blotting. Results: MaR-L1 treatment to the 5XFAD mice showed improved cognitive function of 5XFAD mice. MaR-L1 showed decreased anxiety behavior in open field test and marble burring test, increased muscular strength in the beam walking test, clasping test and inverted grid test. Cognitive function was improved in MaR-L1 treated 5XFAD mice in the novel object recognition test. MaR-L1 prevented neuronal loss and aberrant inflammation. Conclusion: Our finding suggests that behavioral abnormalities were normalized by the administration of MaR-L1 and the neuroprotective role of MaR-L1 in the AD. It also indicates that MaR-L1 treatment is able to prevent and or ameliorate neuronal loss and aberrant inflammation. Further experiments to validate the results are warranted using other AD models in the future. <p class="card-text"><strong>Keywords:</strong> <a
