Gultom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The picture and pattern of Islamic education in the Prophet's period in Mecca and Medina is the history of the past that we need to bring back. The Basic Education Institute called Kuttab. Kuttab or Maktab comes from the word kataba which means to write. The popular Kuttab in the Prophet’s period aims to resolve the illiteracy in the Arab community. In Indonesia, this Institution has 25 branches; one of them is located in Semarang (i.e. Kuttab Al-Fatih). Kuttab Al-Fatih as a non-formal institution of Islamic education is reserved for children aged 5-12 years. The independently designed curriculum is a distinctive feature that distinguishes between Kuttab Al-Fatih curriculum and the formal institutional curriculum in Indonesia. The curriculum includes the faith and the Qur’an. Kuttab Al-Fatih has been licensed as a Community Activity Learning Center under the direct supervision and guidance of the National Education Department. Here, we focus to describe the implementation of curriculum Kuttab Al-Fatih Semarang (i.e. faith and al-Qur’an). After that, we determine the relevance between the implementation of the Kuttab Al-Fatih education system with the formal education system in Indonesia. This research uses literature review and field research qualitative methods. We obtained the data from the head of Kuttab Al-Fatih Semarang, vice curriculum, faith coordinator, al-Qur’an coordinator, as well as the guardians of learners and the learners. The result of this research is the relevance of education system in Kuttab Al-Fatih Semarang about education system in Indonesia. Kuttab Al-Fatih Semarang emphasizes character building through a curriculum designed in such a way and combines thematic learning models in modules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20education%20system" title="Islamic education system">Islamic education system</a>, <a href="https://publications.waset.org/abstracts/search?q=implementation%20of%20curriculum" title=" implementation of curriculum"> implementation of curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuttab%20Al-Fatih%20Semarang" title=" Kuttab Al-Fatih Semarang"> Kuttab Al-Fatih Semarang</a>, <a href="https://publications.waset.org/abstracts/search?q=formal%20education%20system" title=" formal education system"> formal education system</a>, <a href="https://publications.waset.org/abstracts/search?q=Indonesia" title=" Indonesia"> Indonesia</a> </p> <a href="https://publications.waset.org/abstracts/78277/islamic-education-system-implementation-of-curriculum-kuttab-al-fatih-semarang" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78277.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">334</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">93</span> The Views of Teachers, Students and Parents on the FATIH Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eemsettin%20%C5%9Eahin">Şemsettin Şahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20O%C4%9Fuz%20Akt%C3%BCrk"> Ahmet Oğuz Aktürk</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0smail%20%C3%87elik"> İsmail Çelik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the views of teachers, students and students' parents on the FATIH (Movement of Enhancing Opportunities and Improving Technology) Project, which was put into service by the Ministry of National Education in cooperation with the Ministry of Transportation in Turkey in November 2010 for the purpose of increasing students' success and planned to be completed within 5 years. The study group consisted of teachers employed in a pilot school in the province of Karaman in central Turkey included within the scope of the FATIH Project, students attending this school and parents whose children are students in that school. The research data were collected through forms developed by the researchers to determine the views of teachers, students and students' parents on the FATIH Project. The descriptive analysis method, one of the qualitative research methods, was used in the study. An analysis of the data revealed that a large majority of the teachers and the students believed that if computers were used to serve their set purpose, then they could make considerable contributions to education. A large majority of the students' parents, on the other hand, regard the use of computers in education as a great opportunity for the students. The views of the teachers, students and students' parents on the FATIH Project usually overlap. Most of the participants in the study pointed out that the FATIH Project was intended to use technology effectively in education. Moreover, each individual participant described their role in the FATIH Project in accordance with their relative position and stated that they could perform whatever was expected of them for the effective and efficient use and progress of the project. The views of the participants regarding the FATİH Project vary according to the kind of the participants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education" title="education">education</a>, <a href="https://publications.waset.org/abstracts/search?q=FATIH%20project" title=" FATIH project"> FATIH project</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/3098/the-views-of-teachers-students-and-parents-on-the-fatih-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3098.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">441</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">92</span> Laser Beam Bending via Lenses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Remzi%20Yildirim">Remzi Yildirim</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih.%20V.%20%C3%87elebi"> Fatih.

The FATİH Project is intended to integrate technology into all levels of education in Turkey. As part of the FATİH Project that is aimed to complete in 2016, it is intended to initially deliver a tablet PC to every student and teacher. We aimed to detect grade 9 students’ acceptance perception level of tablet PCs during the 2014 – 2015 school year in this study where quantitative and qualitative data collection techniques were used in combination. The study group consisted of 228 grade 9 students of high schools in Istanbul, Ankara, Zonguldak and Bursa in Turkey. Study data was obtained through the “Tablet PC Acceptance Scale” and structured interview forms. Given the results obtained from the study, the mean overall score was 70.08 (3.72 out of 5), which was derived from all the dimensions of the acceptance perception level of tablet PCs in the students’ view. Findings of the study indicate that mean scores for students’ acceptance perception level of tablet PCs did not differ by their gender and their level of use of Information and Communication Technology (ICT). Focus group interviews with students suggest that students did not effectively and actively use the tablet PCs; instead they used the interactive board during classes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acceptance%20of%20technology" title="acceptance of technology">acceptance of technology</a>, <a href="https://publications.waset.org/abstracts/search?q=student%E2%80%99s%20view" title=" student’s view"> student’s view</a>, <a href="https://publications.waset.org/abstracts/search?q=FATIH%20project" title=" FATIH project"> FATIH project</a>, <a href="https://publications.waset.org/abstracts/search?q=tablet%20PCs" title=" tablet PCs"> tablet PCs</a> </p> <a href="https://publications.waset.org/abstracts/40883/investigating-students-acceptance-perception-level-of-tablet-pcs-by-a-variety-of-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40883.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">87</span> Hardware Implementation of Local Binary Pattern Based Two-Bit Transform Motion Estimation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seda%20Yavuz">Seda Yavuz</a>, <a href="https://publications.waset.org/abstracts/search?q=An%C4%B1l%20%C3%87elebi"> Anıl Çelebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysun%20Ta%C5%9Fyap%C4%B1%20%C3%87elebi"> Aysun Taşyapı Çelebi</a>, <a href="https://publications.waset.org/abstracts/search?q=O%C4%9Fuzhan%20Urhan"> Oğuzhan Urhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, demand for using real-time video transmission capable devices is ever-increasing. So, high resolution videos have made efficient video compression techniques an essential component for capturing and transmitting video data. Motion estimation has a critical role in encoding raw video. Hence, various motion estimation methods are introduced to efficiently compress the video. Low bit‑depth representation based motion estimation methods facilitate computation of matching criteria and thus, provide small hardware footprint. In this paper, a hardware implementation of a two-bit transformation based low-complexity motion estimation method using local binary pattern approach is proposed. Image frames are represented in two-bit depth instead of full-depth by making use of the local binary pattern as a binarization approach and the binarization part of the hardware architecture is explained in detail. Experimental results demonstrate the difference between the proposed hardware architecture and the architectures of well-known low-complexity motion estimation methods in terms of important aspects such as resource utilization, energy and power consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binarization" title="binarization">binarization</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware%20architecture" title=" hardware architecture"> hardware architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20binary%20pattern" title=" local binary pattern"> local binary pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20estimation" title=" motion estimation"> motion estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=two-bit%20transform" title=" two-bit transform"> two-bit transform</a> </p> <a href="https://publications.waset.org/abstracts/77730/hardware-implementation-of-local-binary-pattern-based-two-bit-transform-motion-estimation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77730.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">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">86</span> Real-Time Mine Safety System with the Internet of Things</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eakir%20Bing%C3%B6l">Şakir Bingöl</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayram%20%C4%B0slamo%C4%9Flu"> Bayram İslamoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebubekir%20Furkan%20Tepeli"> Ebubekir Furkan Tepeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Mehmet%20Karakule"> Fatih Mehmet Karakule</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20K%C3%BC%C3%A7%C3%BCk"> Fatih Küçük</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20Sena%20Arpac%C4%B1k"> Merve Sena Arpacık</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Taha%20Kabar"> Mustafa Taha Kabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammet%20Metin%20Molak"> Muhammet Metin Molak</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20Emre%20Turan"> Osman Emre Turan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Faruk%20Yesir"> Ömer Faruk Yesir</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C4%B1la%20%C4%B0nan%C4%B1r"> Sıla İnanır</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study introduces an IoT-based real-time safety system for mining, addressing global safety challenges.

The study was conducted at Fatih University Prep School. To collect data 3 classes from the A1 module in English language classes completed a questionnaire known as the English Language Learning Strategy Inventory or ELLSI. The data for the present study were collected from the preparatory class students who are studying English as a second language at the School of Foreign Languages. The students were placed into four different levels of English, namely A1, A2, B1, and B2 level of English competency according to European Union Language Proficiency Standard, by means of their English placement test results. The Placement test was conveyed at the beginning of the spring semester in 2014-2015.The ELLSI consists of 30 strategy items which students are asked to rate from 1 (low frequency) to 5 (high frequency) according to how often they use them. The questionnaire and exit exam results were entered onto SPSS and analyzed for mean frequencies and statistical differences. Spearman and Pearson correlation were used in a detailed way. There were no statistically significant results between the frequency of strategy use and exit exam results. However, most questions correlate at a significant level with some of the questions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=individual%20differences" title="individual differences">individual differences</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20learning%20strategies" title=" language learning strategies"> language learning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20University" title=" Fatih University"> Fatih University</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20language" title=" English language"> English language</a> </p> <a href="https://publications.waset.org/abstracts/28251/individual-differences-and-language-learning-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28251.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">491</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">84</span> Visual Analysis of Picturesque Urban Landscape Case of Sultanahmet, Istanbul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saidu%20Dalhat%20Dansadau">Saidu Dalhat Dansadau</a>, <a href="https://publications.waset.org/abstracts/search?q=Aykut%20Karaman"> Aykut Karaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The integration of photography into architecture was a pivotal point in the journey of architectural representation; photography proved itself useful for the betterment of architecture early on, as well as established itself as a necessary tool in the realm of architecture.

However, the majority of cities focuses mainly on popular smart city projects, which are usually driven by strong private sector, regardless of their characteristics, each city needs to develop customized projects within a tailor-made smart city roadmap to be able to solve its own challenges. Smart city manifest, helps citizens to feel the action better than good reading smart city vision statements, which consists of five elements; namely purpose, values, mission, vision, and strategy. This study designs a methodology for smart city roadmap based on a top-down approach, breaking down of smart city manifest to feasible projects for a systematic smart city transformation. This methodology was implemented in Istanbul smart city transformation program which includes smart city literature review, current state analysis, roadmap, and architecture projects, respectively. Istanbul smart city roadmap project followed an extensive literature review of certain leading smart cities around the world and benchmarking of the city’s current state using well known smart city indices. In the project, needs of citizens and service providers of the city were identified via stakeholder, persona and social media analysis. The project aimed to develop smart city projects targeting fulfilling related needs by implementing a gap analysis between current state and foreseen plans. As a result, in 11 smart city domains and enablers; 24 strategic objectives, 50 programs, and 101 projects were developed with the support of 183 smart city stakeholder entities and based on 125 citizen persona profiles and last one-year social media analysis. In conclusion, the followed methodology helps cities to identify and prioritize their needs and plan for long-term sustainable development, despite limited resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=needs-based" title="needs-based">needs-based</a>, <a href="https://publications.waset.org/abstracts/search?q=manifest" title=" manifest"> manifest</a>, <a href="https://publications.waset.org/abstracts/search?q=roadmap" title=" roadmap"> roadmap</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=top-down%20approach" title=" top-down approach"> top-down approach</a> </p> <a href="https://publications.waset.org/abstracts/97318/a-needs-based-top-down-approach-for-a-tailor-made-smart-city-roadmap" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97318.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">216</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">81</span> CFD Study for Normal and Rifled Tube with a Convergence Check</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharfi%20Dirar">Sharfi Dirar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shihab%20Elhaj"> Shihab Elhaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20El%20Fatih"> Ahmed El Fatih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational fluid dynamics were used to simulate and study the heated water boiler tube for both normal and rifled tube with a refinement of the mesh to check the convergence.

Weight is one of the most significant factors in all electrical machines, and as such, many transformer design parameters are related to weight calculations. This study presents a comparison of the weight of oil type transformers and dry type transformer weight. Oil type transformers are mainly used in industry; however, dry type transformers are becoming more widespread in recent years. MATLAB is typically used for designing transformers and design parameters (rated voltages, core loss, etc.) along with design in ANSYS Maxwell. Similar to other studies, this study presented that the dry type transformer option is limited. Moreover, the commonly-used 50 kVA distribution transformers in the industry are oil type and dry type transformers are designed and considered in terms of weight. Currently, the preference for low-cost oil-type transformers would change if costs for dry-type transformer were more competitive. The aim of this study was to compare the weight of transformers, which is a substantial cost factor, and to provide an evaluation about increasing the use of dry type transformers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weight" title="weight">weight</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-type%20transformers" title=" oil-type transformers"> oil-type transformers</a>, <a href="https://publications.waset.org/abstracts/search?q=dry-type%20transformers" title=" dry-type transformers"> dry-type transformers</a> </p> <a href="https://publications.waset.org/abstracts/49059/weight-comparison-of-oil-and-dry-type-distribution-transformers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49059.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">354</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">76</span> Effect of the Experimental Conditions on the Adsorption Capacities in the Removal of Pb2+ from Aqueous Solutions by the Hydroxyapatite Nanopowders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oral%20Lacin">Oral Lacin</a>, <a href="https://publications.waset.org/abstracts/search?q=Turan%20Calban"> Turan Calban</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Sevim"> Fatih Sevim</a>, <a href="https://publications.waset.org/abstracts/search?q=Taner%20Celik"> Taner Celik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, Pb<sup>2+</sup> uptake by the hydroxyapatite nanopowders (n-Hap) from aqueous solutions was investigated by using batch adsorption techniques.

The model of vehicle used for the analysis was made independent of the number of mesh elements, and the k-epsilon turbulence model was applied during the analysis. Results were interpreted as streamlines, pressure gradient, and turbulent kinetic energy contours around the vehicle at 50 km/h and 100 km/h speeds.

In order to improve durable flame retardancy for cotton part of the blend, polysilicic acid and citric acid monohydrate auxiliaries were added in FR finishing bath at different concentrations. Flammability and characteristic properties of the sample were tested according to relevant ISO standard and procedures. To do so, ISO 6940 vertical flammability test, TGA, DTA, LOI and FTIR analysis have been performed.

Depending on colors, feathers exhibit different glass transition (Tg) temperatures. Long-time heat treatment applied to the feathers emerged influential on the surface quality of the resulting carbon fibers. Fourier Transformation Infrared (FTIR) examination revealed that the extent of disulﬁde bond cleavage is highly associated with the feather melting stability. Scanning electron microscopy (SEM) examinations were employed to evaluate the morphological changes of feathers after pyrolysis. Of all, brown feathers were found to be the most promising to turn into useful carbon fibers without any trace of melting and shape distortion when pyrolysis was carried out at 230°C for 24 hours and at 450°C for 1 hour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poultry%20chicken%20feather" title="poultry chicken feather">poultry chicken feather</a>, <a href="https://publications.waset.org/abstracts/search?q=keratin%20protein%20fiber" title=" keratin protein fiber"> keratin protein fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title=" pyrolysis"> pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20carbonaceous%20fibers" title=" high carbonaceous fibers"> high carbonaceous fibers</a> </p> <a href="https://publications.waset.org/abstracts/9790/a-thermal-analysis-based-approach-to-obtain-high-carbonaceous-fibers-from-chicken-feathers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9790.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">329</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">68</span> Synthesis and Anticholinesterase Activity of Carvacrol Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Sonmez">Fatih Sonmez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alzheimer’s disease (AD) is a progressive neurodegenerative disease and it is the most common form of dementia that affects aged people. Acetylcholinesterase is a hydrolase involved in the termination of impulse transmission at cholinergic synapses by rapid hydrolysis of the neurotransmitter ACh in the central and peripheral nervous system. Carvacrol (5-iso-propyl-2-methyl-phenol) is a main bioactive monoterpene isolated from many medicinal herbs, such as Thymus vulgaris, Monarda punctate and Origanum vulgare spp. It is known that carvacrol has been widely used as an active anti-inflammatory ingredient, which can inhibit the isoproterenol induced inflammation in myocardial infarcted rats. In this paper, a series of 12 carvacrol substituted carbamate derivatives (2a-l) was synthesized and their inhibitory activities on AChE and BuChE were evaluated.

CCFFs were found to be dispersed in ethanol in a significantly shorter time with the high shear processor. The CCFFs treated by both sonication and microfluidization were dispersed in epoxy by sonication. SEM examination revealed that CCFFs were broken up into smaller pieces using the high shear processor while being not agglomerated. Further, DSC, TMA, and DMA were systematically used to measure thermal properties of the resulting composites.

Through this electronic device, it was aimed to make learning the Braille alphabet easier for visually impaired individuals with whom the necessary tests were conducted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visually%20impaired%20individual" title="visually impaired individual">visually impaired individual</a>, <a href="https://publications.waset.org/abstracts/search?q=Braille" title=" Braille"> Braille</a>, <a href="https://publications.waset.org/abstracts/search?q=Braille%20display" title=" Braille display"> Braille display</a>, <a href="https://publications.waset.org/abstracts/search?q=refreshable%20Braille%20display" title=" refreshable Braille display"> refreshable Braille display</a>, <a href="https://publications.waset.org/abstracts/search?q=USB" title=" USB"> USB</a> </p> <a href="https://publications.waset.org/abstracts/15833/electronic-and-computer-assisted-refreshable-braille-display-developed-for-visually-impaired-individuals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15833.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">345</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">65</span> Investigation of Film and Mechanical Properties of Poly(Lactic Acid)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reyhan%20%C3%96zdo%C4%9Fan">Reyhan Özdoğan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zg%C3%BCr%20Ceylan"> Özgür Ceylan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Arif%20Kaya"> Mehmet Arif Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Mithat%20%C3%87elebi"> Mithat Çelebi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food packaging is important for the food industry. Bioplastics have been used as food packaging materials. According to the European Bioplastics organization, bioplastics can be deﬁned as plastics based on renewable resources (bio-based) or as plastics which are biodegradable and/or compostable. Poly(lactic acid) (PLA) has an industrially importance of bioplastic polymers. PLA is a family of biodegradable thermoplastic polyester made from renewable resources. It is produced by conversion of corn, or other carbohydrate sources, into dextrose, followed by fermentation into lactic acid through direct polycondensation of lactic acid monomers or through ring-opening polymerization of lactide. The processing possibilities of this transparent material are very wide, ranging from injection molding and extrusion over cast ﬁlm extrusion to blow molding and thermoforming. In this study, PLA films were prepared by solution casting method. PLAs which are different molecular weights were plasticized with glycerol and the morphology of films was monitored by optical microscopy. Properties of mechanical and film of PLA were researched with the mechanical testing machine. <p class="card-text"><strong>Keywords:</strong> <a
