Investigation of Pre-Service Teachers' Pedagogical Content Knowledge Related to Division by Zero
Authors: Karakus Fatih
Published: August 2023

Although the topic of division by zero has been widely discussed in the literature, this subject is still confusing for students, pre-service teachers and teachers. Because of this, teachers at various grade levels may encounter difficulties in conveying the concept to their students. Therefore, in order to provide students with a strong conceptual understanding of division by zero, it is important to examine the ways that teachers and pre-service teachers structure their instructional explanations about division by zero. The aim of this study was to explore the instructional explanations given by pre-service teachers concerning division by zero, as well as the effects of teacher training programs on these explanations. The study consisted of a cross-sectional design and was carried out with 197 pre-service teachers of elementary mathematics. To determine the pre-service teachers' instructional explanations given at different grade levels, a written questionnaire was used. Analysis of the results revealed that although most of the pre-service teachers gave correct answers related to division by zero, few of them provided conceptual-based explanations. Rather, those who gave correct explanations mainly responded with rule-based statements.

Published: August 2023

The purpose of this paper is to investigate a novice primary teacher's mathematical knowledge in teaching on area measurement. Data was collected from a novice primary teacher of fourteen students in a primary school located in Ankara, Turkey using field notes, video recordings of lessons, and audio recordings of interviews before and after her teaching. Her teaching were analyzed according to dimensions of Knowledge Quartet (KQ) model which included Foundation, Transformation, Connection, and Contingency. Results revealed that the KQ model is an alternative and effective tool for the primary mathematics teaching. Specifically, the novice primary teacher's mathematical knowledge in teaching for area measurement was found to be effective regarding the Foundation and Contingency dimensions. However, she lacked the ability to make connections and use appropriate representations and examples regarding the Connection and Transformation dimensions respectively. Implications and suggestions for the improvement of teachers' mathematical knowledge in teaching are presented.

Published: August 2023

The goal of this study is to analyze undergraduate elementary school pre-service teachers' conceptions and misconceptions of physical and virtual manipulative materials using an interpretive framework. The framework involved the use of the Concrete, Pictorial and Abstract cognitive levels combined with the Virtual-level, or CPVA-framework. The CPVA instrument was used to answer two research questions related to participants' understanding of CPVA-levels using the framework during a mathematics methods course. Pre-, post and follow-up test scores were analyzed. The participants demonstrated improvement from pre-test to post- and follow-up-tests. However, this improvement was limited by their understanding of the Virtual-level.

Authors: Ha Hiep Nguyen , Quoc Quan Nguyen , Hong Thai Giang , Thi San Pham
Published: August 2023

This paper presents experimental and simulation studies on a hydrogen fuel cell
that utilizes hydrogen and oxygen as reactants, making it suitable for specific
vehicles such as submarines and underwater vehicles with air-independent
propulsion systems. A fuel cell prototype with an active area of 25
cm2 was constructed using commercial materials and analyzed in
detail. The experimental data were compared to numerical results obtained by the
ANSYS PEM Fuel Cell Module, and the two sets of results were found to agree
closely across a range of polarization curve observations corresponding to
voltages between 0.93 and 0.29 V. The validated numerical model enables
exploration of internal phenomena, such as mass fractions, water contents, and
current flux density that are difficult to study through experiments. This model
can also aid in optimizing the configurations and characteristics of the fuel
cell components. The findings indicate the potential of using hydrogen fuel
cells in specific applications and highlight the value of combining experimental
and simulation studies to advance our understanding of these systems.

Published: August 2023

Graphene and its derivatives are materials with unique physicochemical properties. A detailed study of these materials allows to consider them prospective biomedical agents for targeted drug and gene delivery, photothermal therapy of cancer, bioimaging, etc. However, this requires a comprehensive studies of their effects on the body tissues, including cells of the immune system.
The aim of our research was to stydy the effects of nanoparticles based on pegylated graphene oxide (GO) upon apoptosis of T lymphocytes derived from blood of healthy donors and Jurkat 5332 cell line. Comparison of these cells will extend our knowledge of the effects of nanomaterials on the cells, and to respond the question, what results obtained with continuous cell lines are valid for normal non-malignant cells. In this work, we used GO nanoparticles (100-200 nm, 1-5 m) coated with linear (LP-GO) and branched (BP-GO) polyethylene glycol (PEG). The cells were cultured for 24 hours at 37 C and 5% CO2with nanoparticles at concentrations of 5 and 25 g/mL. Viability and early and late apoptosis of incubated Jurkat cells and CD3+cells from healthy donors were assessed by flow cytometry. It was found that the small nanoparticles coated with linear PEG at high concentrations (25 g/mL) could significantly reduce the number of live cells and increase the number of cells in late apoptosis. At the same time, large nanoparticles coated with branched PEG at high concentrations (25 g/mL) increased the percentage of T cells in early apoptosis.
Meanwhile, the GO nanoparticles at both concentrations did not affect the viability and apoptosis of Jurkat cells, regardless of the size, concentration, and type of surface function of the particles.
The obtained results suggest that GO nanoparticles exert different effects upon normal and malignant lymphocytes of T lineage. One may assume that these discrepancies could be explained by greater resistance of tumor cells compared to normal T cells. These findings suggests that studies of nanomaterials upon living cells should not be limited to experiments on cell lines, since their properties may significantly differ from those of non-malignant cells.

There is only limited data on B-cell response in post-COVID patients despite its importance in studying the post-infection immunity. The present study aimed to investigate the features of the B-cell response in post-COVID patients, focusing on various B cell phenotypes. Along with the standard immunogram, the following cell phenotypes were examined: common B cells (CD45+, CD3-, CD19+); common memory cells (CD45+, CD3-, CD19+, CD27+); common non-memory cells (CD45+, CD3-, CD19+, CD5+); B1 memory cells (CD45+, CD3-, CD19+, CD5+, CD27+); B2 memory cells (CD45+, CD3-, CD19+, CD5-, CD27+); B1 non-memory cells (CD45+, CD3-, CD19+, CD5+, CD27-); and B2 non-memory cells (CD45+, CD3-, CD19+, CD5-, CD27-). The study revealed a sharp increase in B1 memory cells in 15.3% of post-COVID patients with impaired levels of B1 memory cells. This increase was accompanied by elevated levels of total B memory cells, B1 total lymphocytes (mainly, B1 memory cells), total T lymphocytes, and total IgA. By contrast, the patients with impaired B1 memory cells exhibited a sharp decrease in plasma cells, B2 lymphocytes (both memory and non-memory cells), natural killer cells, T regulatory cells, early activation T cells (CD25+), and C3a complement fragment. These findings suggest a unique immune system disorder characterized by dysregulated B lymphocyte switching from IgM to IgG and IgA synthesis, thus resulting in marked decrease in B2 lymphocyte subpopulations. This disorder may be associated with reduced T regulatory lymphocytes and early activation of T lymphocytes responsible for regulating B lymphocyte differentiation. Furthermore, the patients also exhibited reduced hemoglobin and platelet parameters, thus, potentially, contributing to hypoxia and blood clotting abnormalities. Thus, the phenotype identification of these immune system disorders in post-COVID patients requires non-standard approaches to assessing immune status, thus compicating clinical examination, but highlighting the need for immunocorrective therapies. These findings contribute to better understanding of post-COVID immune system disorders and require further investigation into the underlying causal factors.

Published: August 2023

Our aim was to analyze the effects of the ZP2 peptide, a synthetic analogue of active center of GM-CSF, upon antilysozyme activity (ALA) of Candida.

32 vaginal isolates of Candida spp were used in the work. Five species have been isolated from the vaginal secretions of the conditionally healthy pregnant women taken within a screening program. To study the effect of ZP2 on the ALA of the Candida fungi, the fungal cells were co-cultured with a ZP2 solution in Saburo broth medium at 37 oC for 24 hours. Thereafter, ALA of fungi was determined by photometric method.

It was found that the ZP2 peptide caused a decreased expression of ALA of vaginal Candida spp. Isolates, i.e., loss of ALA in the isolates of C. glabrata, C. tropicalis, C. krusei and some isolates of C. albicans, as well as a decreased level of ALA in C. kefir and other C. albicans isolates. Thus, the synthetic analogue of ZP2 peptide (active center of GM-CSF) showed an inhibitory effect upon the antilysozyme activity of Candida.
Bizans Sanatında Monogram
Authors: MAKTAL CANKO Dilek
Published: August 2023

İsim, unvan veya bir dua belirten bir dizi harfin bileşimi ile oluşan bir sembol olan monogramlar, Erken Hristiyanlık dünyasından itibaren Bizans sembolizminde önemli bir yer edinmiştir. Nomina sacra’dan türeyerek kutsal karakterler için sembol haline gelen kutsal kişilerin monogramları, apotropaik işlev görmüştür. Seküler monogramlar ise, dünyevi kişilerin veya grupların isimlerine atıfta bulunmuşlar ve en yaygın olarak imparatorluk sanat eserleri üzerinde görülmüşlerdir. Bunların işlevleri ise, dini monogramlardan farklıdır. Üzerinde yer aldıkları nesneyle bütünleşerek sahiplik, iktidar ve güç sembolü olmuşlardır. Günümüzde araştırmacılar için monogramların en önemli problemi, harflerin yerleştirilme sistematiği bulunamadığı için okunmasının hipotezden öteye geçmemesidir. Ayrıca, mimari yapılar, mücevherler gibi kişisel kullanım eşyaları, seramik ve tekstil üzerindeki monogramların işlevi hala tartışılmaktadır. Antik çağlardan Bizans’a miras kalan monogramları şekilsel olarak dört kategoriye ayırmak gereklidir: Kutu monogramlar, haç monogramlar, çubuk monogramlar ve yan yana bitişik harf monogramlar. Bu makalede, Bizans görsel kayıtlarındaki monogramların çeşitlerini sistematize etmek ve işlevleri konusunda tartışmak amaçlanmıştır.

Published: August 2023

Yapıştırma; iki veya daha fazla parçanın birleştirilmesinde vida, perçin gibi mekanik eleman ihtiyacı olmadan, yapıştırıcı kullanılarak gerçekleştirilen bir işlemdir. Yapıştırma bağlantılarında çoğunlukla mukavemetin yüksek olması istenir ve bu beklenti yapıştırıcı malzeme seçimini etkileyen en önemli faktörlerden biridir. Bağlantıların mekanik dayanımlarının artması için yapıştırıcıya dolgu maddeleri eklenebilmektedir. Bazı üreticiler ticari yapıştırıcılarının formüllerine gümüş, bakır, çelik, titanyum, alüminyum, bronz gibi metal veya alümina oksit gibi seramik esaslı partiküller eklemişlerdir. Bununla birlikte; dolgu maddeleri eklenerek yapıştırıcıların güçlendirilmesi konusu, gelişen yeni teknolojik malzemeler sayesinde araştırmacıların çalışmalarına devam ettiği bir alandır. Bu çalışmada 3B yazıcı ile PLA Plus filamentten üretilen farklı doluluk oranlarındaki parçalar (%20 ve %100) 2 farklı ticari (Araldite 2015, Loctite 9466) ve 2 farklı ticari olmayan yapıştırıcı (PVC esaslı ve PS-Th esaslı yapıştırıcı) kullanılarak birleştirilmiştir. Bu yapıştırıcılar içerisine ağırlıkça %5 oranında iki farklı dolgu malzemesi (44∼100 μm yumuşak lehim tozu, 45 μm fındık kabuğu tozu) ilave edilmiştir. Yapıştırma işlemi sonrasında bağlantıların mekanik özellikleri incelenmiştir. %100 dolu bağlantılarda Loctite 9466 yapıştırıcı içine %5 lehim ve fındık kabuğu tozu katkısı, bağlantı mukavemet değerini arttırmıştır. %20 dolu bağlantılarda ise yapıştırıcıya dolgu malzemesi eklenmesinin mukavemeti olumsuz etkilediği görülmüştür. Yapıştırılan parçaların doluluk oranları, yapıştırıcı malzemenin sade veya katkı eklenerek kullanılması gibi değişkenlerin bağlantı mukavemetini oldukça etkilediği anlaşılmıştır.

Authors: Fischer Indra Jhon , Tarigan Johannes , Bangun Emma Patricia
Published: August 2023

Kekuatan struktur blok angkur pada jembatan gantung sangat bergantung pada berat sendirinya untuk mampu memikul beban tarik kabel backstay. Oleh karena itu diperlukan dimensi yang cukup besar untuk menahan gaya tarik tersebut. Beton memiliki kuat tekan yang baik namun kurang memiliki kuat tarik yang baik, kuat tarik beton hanya sekitar 10%-15% dari kuat tekannya. Oleh karena itu pada perencanaan blok angkur diperlukan blok angkur yang terbuat dari baja yang memiliki tegangan leleh dan tegangan fraktur yang cukup tinggi dan ditanam pada blok beton angkur untuk menahan gaya tarik sebelum tegangan tarik ditransfer pada blok beton. Pada tulisan ini digunakan baja profil H 300.300.10.15 sebagai angkur baja yang tertanam pada blok beton. Tujuan dari penelitian ini adalah mendapatkan nilai tegangan yang terjadi pada blok angkur dengan menggunakan bantuan program Ansys, memperoleh jarak penulangan yang sesuai pada daerah tarik maksimum (daerah kritikal), dan memperoleh gambaran secara grafis pengaruh geometri struktur angkur akibat beban tarik dari kabel backstay. Penelitian ini dilakukan dengan kajian numerik menggunakan bantuan program SAP 2000 untuk menghitung gaya – gaya dalam pada keseluruhan struktur jembatan gantung, kemudian menggunakan bantuan analisa program Ansys untuk memperoleh tegangan tarik yang terjadi pada blok angkur yang dimodelkan juga pada Ansys dengan boundary condition yang mendekati kondisi yang ada pada lapangan. Hasil analisa Ansys menunjukkan tegangan tarik maksimum terjadi pada baja profil H 300.300.10.15 sebesar 73,27 MPa dan tegangan tarik maksimum pada beton adalah 1,26 MPa. Nilai 1,26 MPa ini masih dalam batas yang aman karena tegangan tarik ini masih dibawah tegangan tarik izin betonnya sebesar 2,23 MPa. Dari hasil analisa empiris diperoleh jarak maksimum tulangan pada daerah kritikal adalah 150 mm, dan pada daerah non kritikal diperoleh 250 mm.

Published: August 2023

Pterophyllum scalare is a popular ornamental fish species, but current rearing methods result in high mortality, low fertility, disease incidence, and slow growth in aquarium conditions. Research on co-feeding for ornamental fish at the juvenile or adult stage needs to be completed. This study implemented a “snacking” feeding strategy using Artemia sp. to evaluate changes in fish survival rate, growth performance, and enzyme activity related to digestion, antioxidants, and immunity in a recirculating aquaculture system. Two feeding strategies were tested: one group was fed a commercial diet plus Artemia sp. (0.1% of diet) as “snacking,” and another group was fed only the commercial diet as normal. “Snacking” with Artemia sp. enhanced fish’s survival and growth performance, with higher relative weight rate, standard length, and total length than the control group. Specific growth rates for weight, standard length, and total length were also more significant in the supplemented group compared to the control group. The activity of amylase, superoxide dismutase, and glutathione peroxidase was substantially higher in the supplemented group. Adding Artemia sp. as a supplement under a “snacking” feeding strategy to the control diet was beneficial for P. scalare juvenile rearing and can guide managing recirculating farming activities.

Abstract

In the European Union, the population uses 26% of the energy. Due to the strategic goal of achieving climate neutrality and the crises of recent years, investment in the use of renewable energies has accelerated. In order to support this process, the Circular Economy Analysis Center of the Hungarian University of Agriculture and Life Sciences (MATE) started the development of a so-called multidisciplinary smart map, which shows the possibilities of renewable energy sources that can be used locally, and the selection of the optimal energy production mix based on the location of residential buildings and buildings. The purpose of this article is to present the selection of test sites necessary for the development of the map, highlighting their geographical, meteorological, economic, and social characteristics. Based on the applied multi-criteria system, the selection of testing locations and tasks is a complex task. The investigations are summarized in five chapters. The first one describes the introductory thoughts related to the initiation and development of the project. The second deals with Hungarian residential energy consumption in the light of international data. The third presents the principles of smart map development and defines the criteria for testing locations. And the fourth one analyzes and presents the principles and possibilities of selecting locations. The fifth part summarizes the location selection process, describes the methodology of the applied analyzes and describes the results of the location selection. The described procedure can guide the examination of these factors in other international projects.

Published: August 2023

Masalah panas berlebih pada motor listrik umumnya diatasi menggunakan beberapa motor listrik yang bekerja secara bergantian (running dan standby). Sayangnya, saat ini pengoperasian beberapa motor listrik masih dilakukan secara manual oleh operator, baik secara langsung maupun melalui komputer. Terdapat beberapa industri yang telah mengoperasikan beberapa motor listrik secara otomatis menggunakan time delay relay (TDR). Namun, penggunaan TDR berdasarkan perubahan waktu yang dinilai kurang efisien dibandingkan dengan penggunaan sensor suhu yang secara langsung mampu membaca suhu motor. Penelitian ini bertujuan menghasilkan sebuah prototipe yang dapat mengontrol dua buah motor listrik secara otomatis berdasarkan perubahan suhu motor. Prototipe tersebut juga dapat memantau suhu motor listrik secara real-time melalui smartphone (aplikasi internet of things-IoT). Terdapat beberapa komponen penyusun prototipe tersebut, yaitu Modul MLX90614 digunakan sebagai sensor suhu dan dua buah modul relay. Kedua komponen tersebut terhubung ke Wemos D1 R2 yang digunakan sebagai prosesor dan sebagai penghubung ke jaringan internet melalui WiFi. Aplikasi Blynk IoT digunakan sebagai platform pengguna untuk memantau suhu motor listrik secara real-time dan mengontrol pendingin. Berdasarkan hasil pengujian, prototipe yang dihasilkan mampu mengukur suhu motor secara akurat dengan error dan % error masing-masing < 0,5oC, yaitu 0,38oC dan 0,44oC. Prototipe tersebut juga mampu menonaktifkan pompa running pada suhu 155oC dan mengaktifkan pompa standby secara otomatis. Selain itu, aplikasi Blynk IoT mampu megontrol pendingin dan menampilkan data suhu motor secara real-time.
Possibilities of Growth, Decent Jobs and Poverty Reduction without Industrialisation: Application of Discrete-Time Markov Process
Authors: Bundala Ntogwa
Published: August 2023

The paper aimed to examine the possibilities of growth, decent jobs, and poverty reduction without industrialisation. The study uses secondary data from 23 countries sampled randomly from developing and developed countries. The discrete-times Markov process was used. The study found that a country such as Mongolia has higher industrial growth but less state transition probability. The study found that the G7 and G20 countries such as Canada, Germany, the USA, Australia, India and Mexico have less industrial growth, resulting in the unpredictability of the growth, decent job creation and poverty eradication. The study concludes that the growth of industrialisation does not grant for growth, decent job creation and poverty eradication, but the industrial structure, policies and location with be determined by such effects. Therefore, the paper recommends using the discrete-Time Markov process to predict the economic growth in developed and developing countries.
