Kaitan Pembelajaran Bahasa Indonesia dengan Lingkungan
Authors: Jannaini Fahlusy
Published: May 2022

Bahasa Indonesia memiliki kedudukan yang tinggi, karena bahasa Indonesia merupakan bahasa resmi bangsa Indonesia. Untuk itu, pengaplikasian bahasa Indonesia dapat diajarkan sejak dini dari lingkungannya, baik itu lingkungan formal maupun informal guna menanamkan nilai-nilai kehidupan dan sosial sejak dini. Lingkungan sekolah mempunyai dampak terhadap pembelajaran siswa di sekolah, karena jika lingkungan sekolah membuat siswa merasa tidak nyaman, maka siswa tersebut juga akan kekurangan fokusnya terhadap pembelajaran, dan jika siswa tersebut tidak fokus pada pembelajaran, siswa tidak akan mengerti apa yang diajari oleh guru didepan kelas. Jadi secara tidak langsung pembelajaran pada sekolah yang memiliki lingkungan yang memadai dan fasilitas yang nyaman, lebih baik dari pada sekolah yang lingkungannya kotor dan fasilitasnya tidak nyaman.
Tempting and Enforcing as Paradigms for the Design of Social Interactions in Social VR
Authors: ECG
Published: May 2022

Developers of Social VR applications have access to individual users' motion data and the resulting spatiotemporal relationship between them via VR hardware. This information opens up the possibility of identifying specific social events like handshakes and making them usable for concrete features that eventually shape the social experience within the virtual world. Following this line of thought, we put the paradigms of tempting and forcing specific social interactions in VR up for discussion to add a novel perspective to the growing body of literature on Social VR design strategies. In this position paper, we first give an illustrative example for linking body movement data and social features, then present a continuum of developer influence on social interactions in VR. In conclusion, we advocate the value of exploring social VR interaction techniques that extend beyond reality.

Authors: Pasande Purnama , Laihad Griet Helena
Published: May 2022

Penelitian ini bertujuan untuk meningkatkan Organizational Citizenship Behavior (OCB) mahasiswa melalui peningkatan peranan budaya organisasi dan kreativitas dosen di era educational 4.0 agar menghasilkan lulusan yang berkualitas. Penelitian ini berawal dari penelitian Peningkatan OCB melalui Pengembangan Budaya Organisasi dan Pengambilan Keputusan (Laihad G.H, 2018). Penelitian lainnya adalah A Study on the Relationship between Cretivity and Innovation in Teaching and Learning Methods towards Student Academic Performance at Private Higher Education institution, Malaysia (Selvi Narayanan, 2017). Penelitian di atas memberikan kesimpulan bahwa OCB dipengaruhi oleh budaya organisasi dan faktor lainnya seperti pengambilan keputusan, sementara kreativitas dosen dalam pembelajaran akan mengembangkan minat dan kreativitas mahasiwa untuk mengetahui lebih jauh konsep yang diberikan sehingga dapat meningkatkan kinerja akademik mahasiswa. Ini dapat diartikan bahwa kreativitas dosen dapat meningkatkan inisiatif individual yang merupakan salah satu dimensi dari OCB. Dalam era educational 4.0, mahasiswa dituntut memiliki karakter yang akan menjadi dasar dalam mengembangkan ilmu pengetahuan yang bermanfaat bagi kemanusiaan. Karakter yang diwujudkan dalam perilaku saling menolong, toleransi, memiliki inisiatif individu, mau mengembangkan diri, patuh terhadap peraturan yang berlaku dan loyal pada organsasinya merupakan ciri dari Organizational Citizenship Behavior. Mahasiswa yang memiliki OCB tinggi akan menjadi asset bagi negara dalam memiliki generasi muda yang cerdas dan berakhlak tinggi.

Peristiwa yang menimpa remaja akhir-akhir ini cenderung mengarah pada kasus kriminal seperti tawuran,bulling atau perampokan. Hal-hal tersebut merupakan gambaran bagaimana lakukan moral remaja sehingga pendidikan karakter dirasa perlu. Karakter perlu diintegrasikan dalam pendidikan formal, sehingga akan diperoleh nilai-nilai baik siswa sejak dini. Sekolah merupakan tempat pendidikan, dimana siswa diarahkan untuk bertindak atau memiliki wawasan pengetahuan (normative). Belajar lebih kompleks karena mengarah pada tujuan kahir, yaitu agar seseorang dapat berperilaku atau memiliki kepribadian (operasional) yang lebih baik. Sebenarnya pendidikan akhlak dan budi pekerti tidak dapat dipisahkan dari pembinaan kerohanian yang merupakan satu kesatuan dalan bahan ajar pendidikan agama Kristen. Pembentukan karakter harus ditekankan secara cermat dan diakualisasikan dalam kehidupan sehari-hari.

Analog experiments in volcanology: towards multimethod, upscaled and integrated models
Authors: Poppe Sam , Gilchrist Johan , Breard Eric , Graettinger Alison , Pansino Stephen
Published: May 2022

For decades scaled analog experiments have improved the understanding of a broad range of multiphase volcanological processes in controlled laboratory environments. Successfully modeled processes include magma flow through magma reservoirs, conduits and sheets, associated crustal deformation, lava flow, volcanic plume dynamics, ash cloud dispersion, pyroclast sedimentation, pyroclastic density currents and debris flows. Prior to the advent of computational modeling in volcanology, analog experiments were the primary method used to test newly developed concepts. Over the past two decades, technological advances have led to increased quantification of model observables, including deformation fields, lava flow rheologies, bubble and particle suspension compositions, runout distances, plume geometries, and rates of ash cloud spreading and sedimentation. For experimental results to yield further insights in volcanic processes and observables directly useful to volcano monitoring efforts, we expect future progress to focus on three major fronts: 1) improved multimethod measurements in experiments; 2) upscaling to near-natural-scale experiments conducted by multidisciplinary teams at internationally shared facilities; and 3) integration with computational models that will guide future geophysical observations and predictions of volcanic activity. This way, analog experiments will bridge gaps between other techniques in volcanology and improve our understanding and forecasting of volcanic activity from the Earth’s mantle to the surface and into the atmosphere.
Library and Information Science Curriculum in Pakistani Universities: A Comparison with Higher Education Commission Approved Curriculum
Authors: Jan Saeed Ullah , Qasmi Zakria
Published: May 2022

The main theme of this research article is to equate the library and information science curriculum taught at Bachelor of Studies (BS) level at the Pakistani schools of library and information science with curriculum designed by the Higher Education Commission of Pakistan. Efforts were made to dig out and download the required information from the websites of the Higher Education Commission (HEC) of Pakistan and schools of library and information science where the BS-LIS program is in functioning mode. In cases of non-availability of the desired information on the concerned university website, the authors consulted prospectuses and also approached the faculty/focal person of the concerned department for the requisite information. Seven out of fourteen LIS schools are offering BS-LIS programs in Pakistan. The majority of these schools follow the guidelines of the HEC in connection with BS-LIS programs in the country. Revision of LIS curriculum by the HEC is currently needed, as course revision has not taken place since 2014. The oldest schools of LIS are required to offer BS-LIS programs, as they have not yet initiated this program. This study is beneficial in designing a market-based curriculum for library science professionals in Pakistan. This attempt also helps the university authorities to make possible the compatibility of their BS-LIS program in line with the HEC curriculum. Uniformity in LIS curriculum at the national level is also a probable output of this study that can assist our professional bodies to achieve accreditation with international bodies.
Publication Output of Lecturers in Library Schools, Nigeria
Authors: Igere Mercy A.
Published: May 2022

In recent times, there has been an observed stagnation of lecturers in terms of academic level growth and non-promotion, which is linked with publication output. This necessitated the investigation of LIS lecturers’ publication output in universities in Nigeria. The descriptive design was adopted using an online questionnaire, which yielded 86 responses. Data generated were analyzed using simple percentages, Tukey HSD tests, and ANOVA. The study revealed that the productivity of LIS lecturers is based on their area of specialty and interest. Factors such as promotion, contribution to knowledge, peer recognition, salary improvement, and staying current (consistency/complete involvement in research activities) were the major reasons that they publish. Time constraints, poor interpretation skills, exorbitant publication fees by journal editorials, and the high rejection rate of manuscripts by journals hinder publications. Statistical significance was observed in the number of publications of LIS lecturers from library schools in various geopolitical areas. The study therefore recommends that financial support from both government and non-governmental organizations should be made available to lecturers. Such funds should be accessible with the provision that there be appropriate feedback on research progress. Departments and institutions can also organize seminars or symposia on the need to collaborate in research, and outline steps on the preparation of manuscripts suitable for publication in reputable journals to avoid rejection by journal editorial boards. There should also be a reduction of workload for lecturers through the provision of work leave/vacation for some period of time to ease work and research tension.
“Librarianship as Citizenship”: The Promise of Community-Based Learning in North American Library and Information Science Education
Authors: Poole Alex H. , Agosto Denise , Lin Xia , Yan Erjia
Published: May 2022

This article argues for the usefulness of experiential learning as a vehicle for democratic civic engagement in North American library and information science programs. First, we explore the literature on service learning, traditionally the primary type of experiential learning in LIS. We define and provide historical context and scrutinize service learning’s benefits and challenges for students, faculty, LIS programs, and parent institutions. Second, we trace the evolution of experiential learning from service learning to community-based learning (CBL); we underline the ways in which such an approach in its epistemology and its practice transcends the traditional service-learning model. Finally, we unpack the novel ways in which one iSchool’s LIS program is implementing community-based learning, namely by embracing data science and design thinking in its pedagogical approach to a new three-course, twelve-credit post-Bachelor’s certificate (PBC). We discuss the institutional context for the certificate, the project partners, the 12 PBC Fellows, and the curriculum, which includes three new courses (Design Thinking for Digital Community Service, Data Analytics for Community-Based Data and Service, and a capstone).
Teaching Reference Interview Skills with Improv
Authors: Vardell Emily , Nelson Sarah Beth
Published: May 2022

This study explores the use of improv guidelines and exercises to explore best practices for the provision of reference services. Existing literature indicates that improv skills have applications in many areas of life, are being used in the higher education classroom, and are being used in libraries. The literature supports the idea that improv exercises could be used to teach reference interview skills. Understanding that soft skills are important for reference librarians, but are not always covered in reference courses, the authors sought to experiment with using improv in class. One of the authors included improv activities during one class meeting of the reference course during three sections over two semesters. During the first semester, the class met face-to-face. During the second semester, the two classes met synchronously online, due to COVID-19. Student feedback collected immediately after the improv activities supports using improv as an innovative teaching approach for encouraging graduate library students to engage with the soft skills needed for effective reference services.
A Systematic Literature Review of Online Learning Spanning 26 Years (1993–2018)
Authors: Singh Vandana , Thurman Alexander
Published: May 2022

This article aims to provide the reader with a comprehensive background for understanding current knowledge on online learning through a systematic literature review of the published literature in peer-reviewed English language journals. We reviewed 5,803 articles published over 26 years (1993–2018). We focused on the number of articles published, journals’ names, and overall research trends about online learning. We reviewed the growth and evolution of keywords, titles, and abstracts to develop an understanding of the growth and fall of trends in research on online learning. We discovered that the dominant trends in the published articles on online learning are learning, students, environment, courses, education, and teaching. The growing areas are online delivery, learning in online setting, teacher (teaching), and students (learners), and we discuss the gaps in the discipline that indicate a potential growth area for the future of the discipline including technology research.
Integration of Information Behavior into Reference and Information Services Education: A Syllabus Study
Authors: VanScoy Amy , Julien Heidi , Harding Alison
Published: May 2022

Information behavior is an important area of conceptual knowledge for reference service providers, as it provides structure for understanding users’ information seeking and use. This study explores the extent to which information behavior theories, models, and concepts have been integrated into professional education for reference and information service (RIS) through a syllabus study and textbook review. In addition, the study identifies specific information behavior theories, models, and concepts used in introductory RIS courses. Syllabi for introductory RIS courses taught at North American library and information science programs were analyzed for information behavior content, as were the textbooks required by the syllabi. Results show that about two-thirds of introductory RIS courses include instruction in information behavior theories, models, and concepts. Overall, the most impactful information behavior theories and models from the literature are introduced.
Scholarship of Teaching and Learning: Evolution of Research on Library and Information Science Education
Authors: Jamali Hamid R. , Nabavi Majid
Published: May 2022

Scholarship of teaching and learning plays an important role in informing educational practices in every discipline. The aim of this study was to identify the trends of research on library and information science (LIS) education. A total of 1,986 articles on LIS education published from 1999 to 2018 were retrieved from bibliographic databases using topical and thesaurus-based queries. They were analyzed for their topics, methods, educational level and aspect, country, and outlet. The results showed that curriculum (what we teach) received more research attention than pedagogy (how we teach). Teaching organization of information (including cataloguing, classification, and metadata) was the most researched topic. Educational aspects of some sectors such as archives and record keeping and academic libraries have received more attention, while some other sectors such as school libraries have not been covered as widely. Survey was the most popular research method used in research articles. There were 134 articles covering LIS education in the United States, representing the greatest coverage by geographic region. While some topics such as serials librarianship and law were discussed in early 2000, in recent years topics such as political literacy, crisis management, privacy, digital humanities, and GLAM convergence have emerged in the literature.
Against the Clock: Speed Training in Library and Information Science Education
Authors: Bowker Lynne
Published: May 2022

We may not always like the speed of today’s world, but we still need to prepare students for working in a fast-paced environment. In the library and information science (LIS) professions today, deadlines are becoming ever shorter, yet research into the effects of time pressure in LIS is scarce. This pilot project aims to develop and test a speed-training program to improve LIS students’ ability to work under time pressure. An experiment is conducted where students in the control group receive no speed training while students in the experimental group complete speed-training exercises. Students provide feedback through surveys and a focus group. The results suggest that speed training can help students learn to work more quickly and that students feel positively about speed training. Therefore, it may be worth including explicit speed-training exercises in LIS programs.

Authors: Yoon JungWon , McCook Kathleen de la Peña
Published: May 2022

Using the Association for Library and Information Science Education (ALISE) 2018 statistical reports, this study reports the current diversity status of LIS students. The findings are as follows: (1) overall LIS graduates’ diversity has improved from 6.79% to 17.47% over the past 30 years, and particularly, the increase in the number of Hispanic graduates is noticeable; (2) however, LIS graduates’ diversity does not follow the trends of the US population diversity: whereas 37% of the US population is minority, 17.43% of LIS graduates are minority students; (3) the ratio of LIS minority graduates (17.43%) is lower than the ratio of LIS minority students (20.70%); (4) larger disparities among LIS students are noticed in the most ethnically diverse states; and (5) the rate of minority students among the top ten LIS schools is lower than those of overall LIS schools, except the Asian group.
Innovation Centers and the Information Schools: The Influence of LIS Faculty
Authors: Marty Paul , Saludo Rienne , U-Seong Kim Castle
Published: May 2022

As universities worldwide develop centers for innovation intended to encourage a culture of technological innovation among their students, what role should LIS faculty play? What is the relationship between technological innovation and LIS education? How can LIS educators help students develop their ability to innovate with emerging technologies? This article presents a case study of an undergraduate course offered by the School of Information at Florida State University that brought together students from different majors in a custom-built innovation classroom simulating the innovation centers that many universities are creating for their students. It evaluates a teaching philosophy that offered students ownership over the structure of the semester, safe opportunities to take risks, and the opportunity to solve real-life problems with technology. The results document the connections between innovation centers and the information schools and show how LIS faculty can influence the development of innovation centers on campus.
Teaching Information and Communication Theories through Arts
Authors: Ibekwe Fidelia
Published: May 2022

This article reports on an experience where arts-informed pedagogy was combined with the traditional lecture-style teaching in a course on information and communication theories delivered at the Masters level in the School of Journalism and Communication Sciences (EJCAM) at Aix-Marseille University in France. After the course content had been delivered orally, students were required to work in groups to create art exhibits that showcased how information and communication theories operated in different historical or contemporary situations in the society. Sixteen impressive art projects were created by the students, and an arts exhibition was held within the school premises. To gauge students’ reception of how the arts-informed pedagogy contributed to their appropriation of the course content, they completed an online survey two months after the course. Their responses showed an overwhelmingly positive reception and demand for more creative modes of learning in information and communication studies. The arts approach complemented the verbal mode of learning by creating a recursive and collaborative learning environment that enhanced students’ participation, self-esteem, and creativity and served to illustrate the interdependence between theory and practice.
How Master of Library Studies Students Learn to Search for Information: A Pilot Study
Authors: McNiff Lindsay , Hays Lauren
Published: May 2022

Master of Library and Information Studies (MLIS) students represent a population for whom literature searching is a core practice and a learning outcome for an entry-level course on information searching. How LIS students learn to find information, though, is not completely clear. Many studies have explored undergraduate searching behavior, but few recent studies have investigated the search behaviors of MLIS students. The purpose of this Scholarship of Teaching and Learning study was to explore the following research questions: (1) How do MLIS students describe learning to search?; (2) What works in helping MLIS students see themselves as better searchers of information?; and (3) What works in helping MLIS students become better searchers of information? Participants articulated that course sequence was important in their development of searching skills, that demonstrable skills and engagement with research improved their view of themselves as searchers, and that course structure, content, and active learning were important factors in their improvement.

Following a revolution in digital information and technological development, both the need for and opportunities in digital preservation education have been growing over the last 30 years. This study aimed to examine digital preservation course content through an analysis of course syllabi to understand what is taught in library schools through the graduate level. Our analysis demonstrates the significant growth in digital preservation education during the last decade but also presents several areas that need to be improved, such as more integration of technology into the courses, providing advanced courses, developing core sets of literature, and developing more content for teaching issues related to ethics and diversity.
“I am Invictus”: Parasport, the Invictus Games, and Disability Performance in Canada
Authors: Blair Kelsey , Johnson Megan
Published: May 2022

En septembre 2017, les Jeux Invictus – une rencontre sportive internationale pour le personnel militaire blessé ou malade – ont eu lieu au Canada, dans la ville de Toronto. Cet article revient sur l’évènement pour examiner la façon dont la performance parasportive, les conceptions de la blessure, de la maladie et du handicap, ainsi que la logique de l’État-nation et de l’armée s’entremêlent. Les rencontres parasportives comme les Jeux Invictus mobilisent des représentations de l’invalidité et du handicap; elles orientent l’opinion publique sur des questions liées à l’invalidité, matérialisent des formes communautaires réelles ou imaginées et donnent l’occasion aux individus de participer à des activités physiques. Abordant les Jeux Invictus par la lorgnette des études sur le théâtre et la performance, cet article met au jour les courants idéologiques complexes et souvent opposés qui les traversent. En particulier, l’article s’appuie sur le concept des écologies de la performance pour montrer que le parasport est une niche sous-théorisée de l’écologie de la performance en contexte d’invalidité au Canada. Par une analyse de la performance, l’article éclaire la logique tortueuse inscrite au cœur des Jeux Invictus, notamment leur lien avec le complexe militaro-industriel et une conception ambivalente de l’invalidité, de la blessure et de la maladie. En définitive, l’article affirme l’importance de nouer un dialogue avec la logique contradictoire des Jeux Invictus au lieu de la désavouer, car, se faisant, on ouvre à la recherche de nouvelles voies pour éclairer les complexités de cette écologie de la performance au dynamisme renversant.
How Do Advanced Micromachining Technologies Affect the Performance of Nitinol Medical Devices?
Authors: Bittigkoffer Lucas , Baumann Martin , Feth Nils-Agne
Published: May 2022

Advanced micromachining processes like laser micromachining, electric discharge machining (EDM) and milling are key processes when fabricating Nitinol medical devices. Unfortunately, each machining process alters the thermomechanical properties of Nitinol - especially around the processing zone. To judge how much this affects the functionality of Nitinol devices, precise knowledge about the micromachining processes applied is crucial. Performance of a medical device from a manufacturer point of view is governed by its geometry. Attainable geometries are linked to the respective machining technology. Lastly the process itself might be limited concerning surface roughness, contour accuracy, and aspect ratio. Ecological aspects include the achievable material removal rate (MRR, volume per time) and necessary post processes. In this work, the authors report on recent developments in the field of micromachining Nitinol, especially in which way the respective technology affects the properties and the design of medical components. A comparative analysis of micromachining technologies is presented.

Published: May 2022

The use of superelastic Nitinol in implants continues to grow as physicians, scientists, and engineers design more novel medical devices to utilize its unique characteristics. As many of these devices are expected to be long-term implants, it becomes critically important to increase our understanding of Nitinol fatigue mechanisms beyond 107 cycles. In this study, the fatigue behavior of Nitinol wire in rotary bend testing was characterized by experimental methods and computational modeling. Fractures occurred in high strain regions as predicted by computational modeling. Furthermore, fractures beyond 107 or 108 cycles were observed and seem to have been initiated by nonmetallic inclusions.
Cumulative Fatigue of Nitinol due to Multiple Applied Cyclic Strains
Authors: Briant Paul , Malito Louis , Schaffer Jeremy , Hamilton Tom
Published: May 2022

Typical S/N type testing to determine the fatigue limit of Nitinol is done over a range of strain amplitudes; however, each specimen sees only a single peak strain amplitude during cycling. The effect of variable loading on Nitinol is therefore not understood. The purpose of this study was to evaluate any potential cumulative fatigue effect of combining low strain amplitude cycles with high strain amplitudes cycles on Nitinol wire apex specimens. A series of fatigue tests were performed to evaluate the fatigue response of Nitinol to variable loading. The results demonstrated that fatigue cycles at lower strain amplitudes can limit the number of higher amplitude cycles to failure in a variable loading scenario. However, the results also indicate that a small number of higher amplitude cycles can dominate the fatigue damage; almost all fractures occurred shortly after completing a section of higher amplitude cycles.
Constitutive Model for Ni-Ti-Fe Shape Memory Alloys Exhibiting Pronounced R-Phase Transformation
Authors: Frost M. , Sedlák P. , Jury A. , Heller L.
Published: May 2022

Specific heat treatment or addition of a ternary element may induce a two-stage transformation sequence in NiTi shape memory alloys (SMA). A typical example of intermediating phases is so-called R-phase, a rhombohedral distortion of the cubic austenitic phase, which exhibits much lower transformation strain and thermal hysteresis than the subsequent transition to monoclinic martensite. In specific alloys, e.g., in NiTi slightly enriched by iron, the temperature and stress intervals in which R-phase is stable are quite broad. Hence, the influence of R-phase on the macroscopic (thermo)mechanical response should be considered when developing and designing products from these alloys. Within this context, tailored constitutive models allowing to reproduce the response in complex loading scenarios without additional experimental effort can be extremely beneficial. This paper presents an enhanced constitutive model for NiTi SMA featuring the R-phase transition. The model recognizes R-phase as a distinct phase, respects the coupled influence of stress and temperature on any phase transformation, and covers reorientation (reconfiguration) of both martensite and R-phase with applied stress. The core of the model consists of two material functions: one captures the energy stored in the material at a given thermodynamic state, the other defines the energy released during dissipative processes, which are considered rate-independent. The model was validated through a direct comparison of experimental tests (isothermal tensile tests, isobaric thermal tests, recovery stress tests) with simulated counterparts.
Effect of Flash Annealing on the Microstructure and Fatigue Life of a Ni-rich NiTi-20 at.% Hf High Temperature Shape Memory Alloy
Authors: Gantz Faith , Wall Michael T. , Young Marcus L. , Forbes Drew J.
Published: May 2022

Typical processing techniques involve thermo-mechanically treating the material such as cold working and subsequent annealing to control grain and precipitate size, shape, orientation, and morphology. Shape memory alloy (SMA) mechanical properties rely heavily on microstructural features such as precipitates and grain size to extend fatigue life. Novel approaches to control microstructural features have used laser anneal on amorphous NiTi thin films to recrystallize grains and short-time annealing on NiTi after angular extrusion and cold-drawn fine wires. A recent study examined rapid thermal annealing (RTA) on Ni-lean NiTi- 10 at.% Hf wires as an effective method for controlling grain size and extending actuation fatigue; however, flash annealing or RTA on Ni-rich NiTiHf high-temperature SMA (HTMSA) wires has not been investigated. Based on a larger study, Ni-rich NiTi-20 at.% Hf HTSMA was down-selected for further processing. This study investigates the effect of flash annealing on the thermo-mechanical properties of a Ni-rich Ni50.3Ti29.7Hf20 HTSMA. Microstructural changes were examined using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and transmission electron microscopy (TEM). Actuation fatigue properties were also evaluated at 300 MPa. The results indicate that flash annealing HTSMA wires is an effective method for controlling grain size and extending fatigue life. The heating rate and time held are crucial parameters to control microstructural features such as grain size and coherency.
KASTAMONU YILANLI DARÜŞŞİFA TAÇ KAPISININ KORUNMA SORUNLARI VE MEVCUT DURUM TESPİTİ
Authors: KONAK Işılay
Published: May 2022

Batı Karadeniz bölgesinde yer alan Kastamonu şehri, sahip olduğu stratejik konum, tarihî altyapı, iklimsel uygunluk vb. sebeplerle tarihî süreçte pek çok medeniyete yurt olmuştur. Bu vesileyle medeniyetlerin kültürel altyapılarının, sanatsal beğenilerinin, teknolojik gelişimlerinin temel kodlarını taşıyan ve farklı amaçlar için inşa edilmiş mimari örneklerine de ev sahipliği yapmıştır. 13. yüzyıl Anadolu Selçuklu taş süsleme sanatının nitelikli özelliklerini taşıyan, Kastamonu’nun tek; Anadolu’nun ise en eski şifahanesi olan Yılanlı Darüşşifası, bu mimari mirasın kısmen de olsa günümüze ulaşan önemli örneklerinden biridir. Anadolu’daki darüşşifalarla birlikte tıbbi mistik folklor uygulamaları ve kullanımları, efsaneleri, Kastamonu mimarisi, inanç turizmindeki yeri, taç kapı süslemeleri ve cephe düzeni vb. açılardan çalışmalara konu edilen Yılanlı Darüşşifasının ve taç kapısının mevcut durumu belgelenerek koruma-onarım bağlamında değerlendirilmemiştir. Yılanlı Darüşşifası koruma ve onarımına ilişkin ulaşılan bilgiler, sadece müdahale tarihlerinin belirtildiği ancak yapılan uygulamalar hakkında detaylı bilgi verilmeyen, oldukça kısıtlı içerikteki bilgilerdir.

The gradient of values of water activity of the product and the corresponding humidity of the environment is the driving force of mass moisture exchange in various thermal and hydrothermal processes, as well as during storage, data on the water activity index are important. This indicator shows the amount of moisture retained in the test specimens, which may bind other compounds and affect the shape and structure of the test specimens, as well as the storage efficiency. Given the growing interest in fuel pellets, it is important to determine the rate of water activity.
Composite granules based on obsolete sludge, peat and biomass (sawdust and buckwheat husks) were investigated. Measurement of thermodynamic parameters of the test samples was performed on a Hygrolab-2 instrument. Microscopic measurements were performed using a Delta Optimal Genetic Pro microscope connected to a computer.
According to the generally accepted classification, fuel pellets belong to the tested samples with low humidity and brittle structure, which indicates a high calorific value. It is noted that the effect on the water activity index of sawdust content, which does not impair the quality of the studied samples but indicates a better ability to absorb moisture than its counterparts. Microphotographs of the granule samples show a significant pore space and a high sorption area, which can adsorb compounds both on the surface of the granules and in micro and mesopores.
For the first time, the water activity index was determined for technical products, such as fuel pellets, the range of values of which is 0.224-0.231. Correlation coefficients are obtained, which have the same value for all types of granules. It is determined that the conditions of the technological process of obtaining fuel granules contributed to the formation of a porous structure, brittle and suitable for adsorption of compounds. This affects the storage conditions of the pellets and their mandatory observance.

One of the strong candidates for biodiesel is Crude Coconut Oil (CCO) but its high viscosity cannot be applied directly without treatment. Therefore, nanocarbon is added to reduce the viscosity of CCO. Nanocarbon is a natural material with semiconductor properties, a good heat conductor, and can attract other molecules. By adding nanocarbon, it is expected to reduce the viscosity of CCO. This study aimed to determine the combustion characteristics of droplets on CCO by adding nanocarbon by 1% and 5%. The method used was a true experiment with droplets, which dripped on the thermocouple with activation energy from the heater. The results showed that CCO burned 0.933s with a droplet diameter of 4.307mm, droplet diameter of 5.472 mm. By adding 5% nanocarbon to CCO, the CCO burned faster, more reactive, and the ignition was shorter than the pure CCO and 1% CCO.

Due to the difficulty to directly study ammonia, the present work investigated the engine performance of lean iso-octane/air mixture to approximate ammonia combustion behaviour. The study was conducted using a single cylinder modified diesel engine that features a spark plug and glow plug in the sub-chamber. The investigations varied the engine speeds (1000 and 1500 RPM), glow plug voltages (6 and 10 volts), excess air ratios (1.4 to 1.8), and ignition timings (-2 to -5 °BTDC). The results suggested improved engine performances with a lower excess ratio and higher glow plug voltage due to more complete and stable combustion. By increasing the engine speed, the lean burn limit was extended and improved the engine performances. Because of the sub-chamber feature, delaying the ignition timing improved the engine performances. A larger excess air ratio was found to increase the sensitivity of the engine performances with the ignition timing. The brake mean effective pressure for all conditions has a coefficient of variation of less than 7%, indicating stable combustion. The results suggested that the current setup can be used to investigate ammonia blended fuel and direct ammonia combustion in future works.
Four new species and one new genus of Jurassic chitons (Mollusca: Polyplacophora: Lepidopleurida) from the Middle Russian Sea
Authors: Sirenko B.I.
Published: May 2022

Four new species and one new genus: Leptochiton shapovalovi Sirenko sp. nov., L. liapini Sirenko sp. nov., L. dellangelloi Sirenko sp. nov., and Hoarechiton guzhovi Sirenko gen. nov. et sp. nov. are described from the Middle Russian Sea (Jurassic). L. shapovalovi is probably a xylophagous chiton because this species was found along with pieces of sunken wood and has an aesthete group very similar to some recent xylophagous species. It speculated that the genus Leptochiton was formed under rather temperate or cold conditions in the end of the Paleozoic.

Published: May 2022

The results of statistical analysis of morphological characters and the study of the cytochrome b gene variability (mtDNA) of rock lizards of the Darevskia (saxicola) complex distributed in the Caucasus and the Crimea, have shown significant differentiation within this complex, assuming specific independence of D. szczerbaki (Lukina, 1963) and subspecific status of recently described D. brauneri myusserica Doronin, 2011. According to our data, within D. brauneri (Mehely, 1909) only two forms of subspecific status can be distinguished, namely D. b. brauneri and D. b. myusserica. In our opinion, Lacerta saxicola darevskii Szczerbak, 1962 (= D. brauneri darevskii) should be considered to be a junior synonym of D. b. brauneri. The possible scenarios of range formation in the Darevskia (saxicola) complex are discussed.
