Published: December 2020

Binalarda kullanılan enerji miktarı hem ülkemiz hem de küresel ölçekte toplam enerji tüketiminde önemli bir paya sahiptir. Bu durum tükenebilir enerji kaynaklarının kullanımı, bu kullanım sonucu oluşan çevresel kirlilik ve ekonomik faktörler de dikkate alındığında konfor koşullarının sağlanması noktasında enerji etkin bir mimari tasarımı zorunlu kılmaktadır. Enerji etkin yapı tasarımı çevresel iklim, yön, hakim rüzgar vb parametrelerden yararlanıp aktif/ pasif yöntemler kullanarak ısıtma-soğutma-havalandırma ve doğal aydınlatma konularında yapı performansını arttırarak enerji korunumu sağlamayı hedeflemektedir. Geleneksel binalar bugünkü gibi kapsamlı ısıtma, soğutma, aydınlatma vb sistem desteğine ihtiyaç duymadan pasif tasarım yöntemleriyle istenilen konfor seviyelerini sağlamaktadırlar. Bu çalışma mimari açıdan konfor koşullarının sağlanması için geleneksel bir yapı örneği üzerinden yeni bina tasarımlarına referans olabilecek deneyimleri ortaya koymayı hedeflemektedir. Bu amaçla Design Builder yazılımı ile daha önce konfor koşulları incelenmemiş Harput Şefik Gül Evi’nin simülasyon yolu yıllık ısıtma, soğutma ve aydınlatma yükleri belirlenmiştir. Binanın farklı yönlenme durumları için hesaplanan enerji gereksinimleri tartışılarak, farklı mahallerin yıl içerisinde konfor aralığında kalma süreleri tespit edilmiştir.

Published: December 2020

Bu çalışmada kanola, soya ve atık ayçiçeği yağlarından baz katalizörlü transesterifikasyon reaksiyonu uygulanarak biyodizel üretilmiştir. Bu yağlardan üretilen biyodizeller TS-EN 14214 standarlarına uygun olduğu araştırılmıştır. Üretilen yakıtlar dizel yakıtla %5, %10 ve %20 oranlarında karıştırılarak üç silindirli direkt püskürtmeli bir dizel motorda test edilmiştir. Motor performans ve emisyon karekteristikleri dizel yakıt ile kıyaslanmıştır. Ayrıca biyodizel ve dizel yakıt kullanılması durumundaki elektrik üretim maliyetleri karşılaştırılmıştır. Deneysel sonuçlara göre; biyodizel karışımlarının dizel yakıt ile benzer özellikler gösterdiği tespit edilmiştir. Dizel yakıt içerisindeki biyodizel oranının artması ile özgül yakıt tüketiminde ve egzoz çıkış sıcaklığında artış gözlenmiştir. Motordaki biyodizel kullanımı dizel yakıt ile kıyaslandığında HC, CO, duman emisyonlarında düşüş, CO2, NOX ve O2 değerlerinde artış olduğu görülmüştür. Yapılan motor testleri sonucunda biyodizel ve karışım yakıtlarının dizel motorda yapısında değişiklik yapılmadan kullanılabilirliği sonucuna varılmıştır. Biyodizellerin yağlama özelliği olduğundan dolayı aşınmalar konusunda dizel yakıta kıyasla daha fayda sağladığı görülmüştür. Ayrıca hava kirliliğini azıltıcı etkisi olduğu için dizel motorlar için alternatif bir yakıt olacağı görülmüştür. Test yakıtları arasında en düşük üretim maliyetinin atık ayçiçeği yağı biyodizeli olduğu tespit edilmiştir. Dizel yakıt kullanımında 1 kW elektrik, 2.12 TL'ye üretilirken, %20 oranında atık ayçiçeği yağı biyodizeli (AAYB20) yakıtının kullanımında ise 1.99 TL bedel karşılığında üretilmiş olduğu tespit edilmiştir.

In this paper, we deal with parenting style and students` religiosity. Parenting styles, according D. Baumrind, authoritative, authoritarian and permissive, are viewed through their dimensions, the first through dimensions of connections, regulation and autonomy, and the second through dimensions of coercion, verbal hostility and notexplaining. Religiosity, according Glock and Stark, is viewed through the dimensions of belief, ritual and consequences. The survey was organized with the aim of finding a correlation between parenting style and religiosity of students. We used descriptive methods, scaling techniques, as instruments, assessment scales. The sample consisted 200 students from various University of Serbia, who evaluated the parental procedures of their parents, father and mother separately, and expressed personal views about religiosity. Results of the research show that the most common parental style is authoritative, that the parental styles of parents associated with sex of students, socio-economic status of the family and place of residence. The average score of students’ religiosity is associated with sex and place of residence of students, and according to the ritual dimension with fathers education. The only connection between parenting style and religiosity of students, is negative, and refers to coercion as a dimension of fathers authoritarianism and ritual and consequences, as well as the dimensions of religiosity. So, there is no statistically significant correlation between parenting style and religiosity of students, in general terms, except the coercion as a fathers parental procedure which is associated with ritual religiosity and consequences, in terms that the coercion pronounced by the father means less expressed practical religiosity. It turned out that religiosity is, indeed, a specific phenomenon that is quite difficult to realistically perceive and quantify, and our recommendation is to do so by combining quantitative and qualitative approaches, respecting the pluralism of scientific paradigms to avoid unambiguous interpretation of collected facts, which would enabled an integral, multidisciplinary understanding of the problem.

The structural-phase state and tribotechnical properties of gas-thermal coatings made of Ni-Cr-Al pseudoalloy are investigated in the initial state and after annealing in the temperature range of 550-650 °С with holding time of 20–60 min. It is shown that in coatings sprayed by the method of high-speed metallization of wires made of Х20Н80 (Kh20N80) and aluminum АД-1 (AD-1), the phase composition includes γ-(Ni, Cr, Fe), Al and Al2O3. It is found that high-temperature annealing of Ni-Cr-Al coatings leads to the precipitation of intermetallic compounds Al3Ni, Ni2Al3, Ni3Al, and NiAl in them, as well as to an increase in the porosity of the coatings up to ≈15–20 vol.%, which is associated with the implementation of the Frenkel and Kirkendall effects. Tribotechnical tests of coatings are carried out according to the scheme of the reciprocating movement of the sample along the plate counterbody in the dry friction mode at a load of 1.5 MPa. It is shown that as a result of the annealing of the coatings, an increase in their wear resistance under dry friction conditions is registered up to 24 times in comparison with the initial state. In particular, the intensity of mass wear of the Ni-Cr-Al coating in the initial state is 28.7 × 10–3 mg/m, and those subjected to annealing at 600 °C for 60 min — 1.2 × 10–3 mg/m. Based on the carried out multifactorial experiment, it is found that the maximum wear resistance of Ni-Cr-Al-pseudo-alloy coatings under dry friction conditions is achieved as a result of their annealing at temperatures of 630–640 °С and a holding time of 40–50 min, which is associated with the release of large number of dispersed intermetallic phases Ni3Al and NiAl with a relatively insignificant increase in the porosity of the coatings.

Published: December 2020

Energy state of composites obtained by mechanical alloying of the Cu-Sn and Fe-Ga powder mixtures during high-energy processing in the planetary ball mill is evaluated by the methods of X-ray diffraction analysis (XRD) and differential scanning calorimetry (DSC). It is shown that during mechanical alloying the total amount of accumulated energy can reach 80 % of the composite melting enthalpy. The greatest contribution to the structuralphase transformations is made by the phase changes of elastic deformations and grain boundaries. The obtained XRD data are consistent with the DSC data. Three endothermic effects are established at temperatures of 507, 792 and 905–1085 °C for the mechanocomposite with the composition Cu20Sn, the value of these thermal effects is significantly reduced (to 0.79, 16.29 and 36 J/g, respectively) relative to an alloy of similar composition obtained by metallurgical methods. The following criteria of estimation of the most probable processes of structural-phase transformations are proposed based on the energy state of mechanocomposites: the structure of the composite is activated at ΔEε << ΔEs; new phases (solid solutions, intermetallic compounds) are formed at ΔEε ≈ ΔEs; the structure ordering processes take place at ΔEε > ΔEs. The decrease in the values of the energy of elastic deformations ΔEε during prolonged mechanical alloying may indicate the increase of the role of the diffusion processes and the formation of ordered structures, which will contribute to the increase of thermal stability of the grain boundaries. According to these criteria, the dose of the introduced mechanical energy to obtain hardened mechanocomposites of the Cu-Sn composition is to meet the conditions: D ≥ 3.4 kJ/g for Cu-Sn mechanocomposites; D ≥ 37.8 kJ/g for Fe-Ga mechanocomposites.

El objetivo de este estudio fue conocer qué investigaciones de carácter longitudinal se han llevado a cabo que hayan analizado variables relacionadas con el sobrepeso, la obesidad y el sedentarismo en edad escolar, y qué datos se pueden extraer de las mismas. Se revisaron las siguientes bases de datos: MEDLINE (PubMed), Scopus, SportDiscus y WOS (Web of Science). Dicha revisión fue realizada siguiendo el modelo PICOs, y a partir de él, se constituyó el protocolo de búsqueda utilizando términos que definan o representen a niños y jóvenes en edad escolar, que puedan presentar o no sobrepeso u obesidad y sedentarismo. Siguiendo el procedimiento Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), de los 2237 estudios encontrados tan solo 28 cumplieron todos los criterios, por lo que fueron analizados en su totalidad para poder ser incluidos en la revisión. La calidad metodológica de los estudios se evaluó mediante la escala Newcastle-Otawa. De los 28 estudios seleccionados finalmente, 13 tenían una calidad metodológica buena, mientras que los 15 restantes tenían una calidad aceptable. Tras realizar la revisión, se puede concluir que el sedentarismo se ve aumentado paulatinamente con la edad mientras que la actividad física decrece, y consecuentemente, esta situación hace que el sobrepeso y la obesidad se vean incrementadas.

Published: December 2020

The project consists of Spinning LED display using RF which displays the messages send by the user at the handheld device. if there are no inputs from the user for the system, the message that is programmed in the microcontroller will be displayed continuously. The circuit needs to be mounted on a mechanical structure that rotates at high speed. The display consists of 7 LEDs only in a vertical row. By moving them fast enough, message can be displayed which appears to be generated by a 7*n matrix of LEDs and not a single column of LEDs, where n is the no. of columns of the display matrix. This illusion is based on inertia of human eye or in other terms PERSISTANCE OF VISION. It consists of motor and seven LEDs that are arranged in a vertical line. The motor spins at a constant rate such that the LEDs rotate around a centre pivot point. As the LEDs spin around they light up sequentially such that they will display the message. The motor spinning fast enough that the human eye will perceive all of the display is on at once, and the viewer will be able to read the message completely. If LED formed message will periodically and frequently enough flash, they will appear solid and steady. A microcontroller is used to keep the message and blink the LEDs in an appropriate pattern. It has to be programmed so that it will both keep message and also send the appropriate signals to the LEDs to light them in the correct sequence.

Published: December 2020

An implementation of the Data Encryption Standard (DES) algorithm is described. Protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data. The algorithms uniquely define the mathematical steps required to transform data into a cryptographic cipher and also to transform the cipher back to the original form. The proposed pipeline method is for improving the speed of execution when compare with the non-pipeline method.

With the increase in silicon densities, it is becoming feasible for compression systems to be implemented in chip. A system with distributed memory architecture is based on having data compression and decompression engines working independently on different data at the same time. This data is stored in memory distributed to each processor. The objective of the project is to design a lossless data compression system which operates in high-speed to achieve high compression rate. By using the architecture of compressors, the data compression rates are significantly improved. Also inherent scalability of architecture is possible. The main parts of the system are the data compressors and the control blocks providing control signals for the Data compressors, allowing appropriate control of the routing of data into and from the system. Each Data compressor can process four bytes of data into and from a block of data in every clock cycle. The data entering the system needs to be clocked in at a rate of 4 bytes in every clock cycle. This is to ensure that adequate data is present for all compressors to process rather than being in an idle state.

Published: December 2020

In Wireless Sensor Networks, Broadcast communication is the most fundamental and prevailing communication pattern. Securing the broadcast messages from the adversary is critical issue. To defend the WSNs against the adversary attacks of impersonation of a broadcast source or receiver, modification/fabrication of the broadcast message, attacker injecting malicious traffic to deplete the energy from the sensors, broadcast authentication of source and receivers becomes extremely inevitable. In this paper, we propose a novel ECC based public key distribution protocol and broadcast authentication scheme. The proposed method provides high security and has low overhead.
EBDP BUFFER SIZING STRATEGY 802.11 BASED WLANS
Authors: BABU CH VASU , HARINI P.
Published: December 2020

In this paper we present wired routers, for whom the sizing of buffers is an active research topic. The classical rule of thumb for sizing wired buffers is to set buffer sizes to be the product of the bandwidth and the average delay of the flows utilizing this link, namely the Bandwidth-Delay Product (BDP) rule. Surprisingly, however the sizing of buffers in wireless networks (especially those based on 802.11/802.11e) appears to have received very little attention within the networking community. Exceptions include the recent work in relating to buffer sizing for voice traffic in 802.11e WLANs, work in which considers the impact of buffer sizing on TCP upload/download fairness, and work in which is related to 802.11e parameter settings.

Making visible the affective dimensions of scholarship in postgraduate writing development work
Authors:   Rhodes University, South Africa, Clarence Sherran
Published: December 2020

Many university writing and student academic development centres serve both under- and postgraduate student-writers. However, it is not always clear that the training and development of those who work with writers accounts fully for the affective dimensions of postgraduate writing, specifically. Especially at the doctoral level, where an original contribution to knowledge is required, writers need to take on a confident authorial voice in their work, both written and in conversation with others. Research, however, shows that many doctoral students struggle with this. This paper argues that, to be truly successful and fit for purpose, peer writing development work needs to understand the nature of postgraduate learning and writing from more than just the technical perspective of writing a successful thesis. Writer-focused work at this level needs to account for the affective dimensions of writing and research as well, to engage students in more holistic, critical, and forward-looking conversations about their writing, and their own developing scholarly identity. The paper offers insights into the different affective dimensions of postgraduate writing, especially those under-considered in much practical work with postgraduate writers, and offers suggestions for a whole-student tutoring approach at this level.

Mobile instructional app (MIA) is a set of instructions put together as a program usually installed on mobile devices to facilitate learning and improve academic performance. MIA helps to motivate students for the enhancement of positive academic performance, thus, it could be utilized in an individualized or in a blended learning environment to supplement traditional teaching-learning process. This study investigated the effects of mobile instructional app on undergraduate students’ academic performance in economics in Sokoto State. The study adopted quasi experimental with a pre-test and post-test, non-equivalent comparison involving 2x2 factorial design.All undergraduate students in Sokoto State formed population of the study. A total of 61 undergraduates formed the sample for the study, 34 for experimental group one (23 males and 11 females) from Sokoto State University (SSU) and 27 for experimental group one (22 males and 5 females) from Usmanu Danfodiyo University Sokoto (UDUS). Pilot study was carried out at Federal University Birnin Kebbi using twenty 100 level undergraduates. Economic Principles Test Instrument (EPTI) was used for data collection. Reliability coefficient of 0.78 using Kuder Richardson 20 (K-R, 20) was obtained. Research hypothesis one was tested using analysis of covariance (ANCOVA), while hypothesis two was tested using t-test statistics. The study found among other that the app was academically effective. There was significant difference in the achievement of the undergraduate students exposed to mobile instructional app and those taught using blended approach (F (1, 58) = 13.649, p<0.05) in favour of experimental group 2. There was no significant difference in the academic performance of the undergraduate students taught in a blended learning environment based on gender. The study concluded that the mobile instructional app (MIA) enhanced the academic performance of undergraduates from the two universities (UDUS and SSU) irrespective of gender. It was established by the study that the undergraduates taught in a blended learning environment out-performed those exposed to MIA alone. The study therefore recommended that lecturers should endeavour to develop and utilize mobile instructional apps that are in line with new NUC benchmark to supplement teaching process.

The degree at which some issues can be meaningfully discussed ethically arises from the nature of the issue at hand. Some issues are axiomatic, ambiguous and controversial mainly because there are evidence in dispute. In scientific research, and in the development and applications of technology, notably live saving technology. Scientists are confronted with ethical problems in their choice of research and education, and in ways and manner they deal with publications and media. The application of science and technology has chain of causes and effect on almost all areas of our lives. The social media, the globalization, the growing cultural pluralism, conflict and war. The development of new weapons, non-sustainable development, depletion of resources, and environmental degradation. Many of these possibilities that are opened by science and technology are harmful and retrogressive. Though, science also proffers possible improved living conditions, improved healthcare, and more awareness of the needs of people in other parts of the world and greater possibilities to assist them. However, the ethical gurus may lack the wherewithal to tackle some of the problems identified in terms of science and technology, they may still be able to say something useful about whether it is acceptable to indulge in a given risk such as stem cell research, GMO research, euthanasia, abortion, falsifying of data and other forms of research that may involve a colossal damage that could have some ripple effect on society and the environment. Ethical literacy, ethical imperative and Ethical bargain becomes a tool at hand.
O GÊNERO RESUMO ACADÊMICO E AS CIÊNCIAS AGRÁRIAS: UM OLHAR SOBRE A PRODUÇÃO TEXTUAL DE PESQUISADORES GAÚCHOS NA REVISTA CIÊNCIA RURAL
Authors: Damiani Schmidt Sabrina , Regner Ana Paula
Published: December 2020

Partindo da concepção de gênero como uma classe de eventos comunicativos, cujos membros compartilham um conjunto de propósitos comunicativos (SWALES, 1990), objetivamos neste artigo identificar como se dá a organização do gênero resumo acadêmico na área das Ciências Agrárias. Para tanto, constituímos nosso corpus de 6 resumos acadêmicos produzidos por pesquisadores gaúchos enviados para os números 3 e 4, do volume 49 da revista Ciência Rural (UFSM). Posteriormente, analisamos os resumos com base na estrutura esquemática proposta por Motta-Roth e Hendges (2010). A partir disso, nossos resultados apontaram para: i) predominância dos Movimentos 2 e 4: apresentar pesquisa e sumarizar resultados; ii) pouca recorrência no Movimento 1: situar pesquisa; iii) nas recorrências do Movimento 1, o mesmo não se insere no Submovimento de generalizações do tópico; iv) no Submovimento do Movimento 2, o destaque é a apresentação dos principais objetivos. Além disso, identificamos falta de linearidade na construção dos resumos analisados, visto que muitos possuem dois Movimentos ao mesmo tempo. Dessa forma, os resultados apontam para o contexto de produção e circulação de resumos acadêmicos da área em questão, bem como estruturas articuladas com o propósito comunicativo.
