Constant Mean Curvature Surfaces Along a Spacelike Curve
Authors: BAYRAM Ergin
Published: September 2022

We construct constant mean curvature surfaces along a given spacelike curve in 3 dimensional Minkowski space. We parametrically present these surfaces using the famous Frenet frame of the curve in question. We give the sufficient conditions for the so called marching scale functions, which are the coefficients of the Frenet frame fields. We show that it is possible to obtain such surfaces for any given spacelike curve. Finally, the validity of the presented method is supported with illustrative examples.
Investigation of the Effect of Different Synthesis Methods on the Photocatalytic Activity of TiO2: Comparison of Rutile and Anatase TiO2
Authors: KILIÇ DOKAN Fatma
Published: September 2022

In this study, the effect of the synthesis method (solid state, sol-gel and hydrothermal) on the photocatalytic activity of the anatase and rutile phases of TiO2 was evaluated. As a result of XRD, FESEM and BET analysis of pure phase TiO2 powders in anatase and rutile phases, the changes in particle structures, surface areas and morphologies were examined and the differences in both synthesis method and phase structures were evaluated with Photodegradation experiments. The results of the X-ray diffraction (XRD) analysis showed that the TiO2 compound synthesized in the anatase phase and by the synthesized hydrothermal method exhibited a much smaller crystal size than the other synthesis methods and the rutile phase. Surface morphology examinations of the samples were made with scanning electron microscopy (FESEM), particle sizes were determined in the range of 90-200 nm, and their surface areas were examined by Brunauer–Emmett–Teller (BET) analysis.The adsorption-desorption isotherms shown also support the XRD data of the highest surface area.The photocatalytic behavior of the compounds was investigated using methylene blue degradation.As a result of all the syntheses and characterization studies, it has been shown that TiO2 obtained by hydrothermal method exhibits the best photocatalytic activity.

Authors: TUTAR Uğur , ÇELİK Cem
Published: September 2022

Today, the number of antimicrobials used in treatment has decreased, especially due to drug resistance. We need new antimicrobials. Biofilms are an important cause of antimicrobial resistance. In this study, the antimicrobial and antibiofilm properties of the salt and silver complex of benzimidazolium-based NHC compound, which were previously synthesized and characterized, were evaluated. The antimicrobial properties were tested using the broth microdilution method, while their antibiofilm potential was determined by microtiter plate assay. Salt of the NHC compound (1a) showed antimicrobial activity on microorganisms at concentrations between 31.25-125 µg/mL. The silver complex (2a) of the NHC compound showed higher antimicrobial and antibiofilm activity than the salt compound. This activity was highest on Candida albicans yeast (MIC 3.9 µg/mL). Compound 2a reduced the biofilm structure of C. albicans yeast by 86.1% compared to the control. In addition, compound 2a showed 76.4-80.6% antibiofilm activity on gram-negative bacteria. NHC compounds are seen as a promising resource for the development of new generation antimicrobials. The NHC compound evaluated in this study was found to have significant antimicrobial and antibiofilm activity. These compounds could be an important resource for the discovery of future biofilm-acting antimicrobials.

Published: September 2022

PISA 2015 mathematical literacy score of Turkey is 420 while the average score of all countries is 461. It is understood that; Turkish students’ PISA 2015 mathematical literacy score was lower than the average. The basic reasons for the below average score need to be truly examined and developmental activities should be revealed. The aim of this study is to classify students according to the factors affecting their mathematical literacy score and to reveal the effects of these factors in classification.The data of the study is obtained from 5895 students who participated in PISA 2015. In this study, we used Random Forest, Naïve Bayes Classifier, Logistic Regression, Decision Tree Algorithm and Discriminant Analysis as classifiers. According to the results, Random Forest method produced more accurate scores than other methods with 76.32% accuracy. We also calculated the correct classification rate and determined the factors that positively and negatively affect the classification with discriminant analysis. According to the discriminant analysis home possessions, information and computer technology resources at home and students' expected occupational status were the most positive effective variables on mathematical literacy score. On the other hand, family wealth possessions, student-related factors affecting school climate and anxiety have negative effect on mathematical literacy score.

AIM: To assess individual subjective chronotypic properties in residents of Khanty-Mansiysk under the influence of such biotropic and social stress factors as regular daytime and aperiodically presented shift daytime and nighttime employment.
MATERIALS AND METHODS: This study involved students (100 girls and 53 boys) of Khanty-Mansi Autonomous Okrug Yugra with a daily study load and employees of the Ambulance station (31 women and 26 men) in Khanty-Mansiysk, working in shifts. The photoperiodic chronotype stability was studied using the computer program Photoperiodic chronotype stability calculator (registration no. 2019661664) in the form of a mobile application for Android Photoperiodic stability index.
RESULTS: The photoperiodic stability of the chronotype in women was: with regular daily employment 3.5 (1.56.0) arb. units, with shift work 1.0 (04.0) arb. units. The photoperiodic stability of the chronotype in men was: with regular daily employment 3.0 (1.04.0) arb. units, with shift work 1.5 (03.0) arb. units.
Volunteers with a regular daytime job tended to choose to shift activities to the afternoon and refusing morning activity. In the group with shift work, the proportion of people preferring the morning type of work capacity was higher. In the group with shift and night work, there were no representatives of a definitely morning chronotype among women, and definitely an evening chronotype among men. In the summer season, male and female respondents, regardless of the production regime, showed an increase in the signs of the morning chronotype.
CONCLUSION: The production and intersexual features of the chronotypological properties of the inhabitants of the North have been established. With the superposition of extreme climatic and geographical factors and social and production conditions, a general pattern of increased rigidity of the chronotype was recorded. Male and female respondents under different production regimes, when assessing subjective biorhythmic performance in the summer, demonstrated a shift toward the morning chronotype.
Explosion Discrimination Using Seismic Gradiometry and Spectrally Filtered Principal Components: Controlled Field Experiments
Authors: Challu Cristian , Poppeliers Christian , Punoševac Predrag , Dubrawski Artur
Published: September 2022

Spectrally filtered principal component analysis (SFPCA) is a method we developed to discriminate between seismic source types. It is based on the well-known principal component analysis but applied to seismic gradiometric data. In this article, we build on our previous efforts by testing the method on data collected in a small-scale field experiment using two source types generated by manually striking the ground at various source–receiver distances (source type A) and orientations relative to the ground surface (source type B). Using the SFPCA method that we originally developed in Challu et al. (2021), we found that we can achieve good discrimination performance for a wide range of experimental geometries and noise conditions. In addition to testing the SFPCA method using a supervised learning approach, we present an SFPCA-based discrimination method using an anomaly detection paradigm. Specifically, given a population of event-specific data (e.g., source type A), we demonstrate that an event with source type B will fall outside the accepted population range of source type A. Thus, SFPCA may have value as a seismic discriminant in the form of an anomaly detector, which may be useful if a sufficient training dataset is not available.
Aquatic insect response to flow regimes and climate change in two terminal basins
Authors:   , Erdenee Bolortsetseg , Gelhaus Jon K , Potapova Marina
Published: September 2022

The focus of this research is the flow-ecology relationship and climate vulnerability of two terminal basins on two continents: the Great Basin in the United States (US-TB) and the Central Asian Internal Drainage in Mongolia (MN-TB). These northern hemisphere basins are located within two of the largest temperate steppe biomes in the world and correspond to semiarid desert steppes. Comparison of these terminal basins can help us understand both similarities and differences within similar ecoregions that are widely separated geographically. A comparison of streamflow characteristics was conducted using streamflow variabilities at Functional Process Zones (FPZs), which are the study units of macroscale comparison with different valley-scale hydrogeomorphic characteristics. The streamflow variabilities calculated from continuous daily streamflow data spanning 1990-2014; indicated that streamflow was characterized by longer seasonal high flow in MN-TB and larger minimum flow in US-TB, and four distinct streamflow patterns were established: extended high flow and frequent flooding in MN-TB and highly variable and large baseflow in US-TB. Hence, the larger minimum flow defined high taxa richness in US-TB and the longer seasonal high flow was responsible for the high heterogeneity of aquatic insect assemblages in MN-TB, whereas the four streamflow patterns selected taxa with relatively different functional traits. Among taxa with climate-sensitive traits at FPZs with the four streamflow patterns, warm-water taxa were predicted to be more vulnerable when they also have a preference for slow-moving water conditions. Among the four streamflow patterns, FPZs with the highly variable flow were the most sensitive to projected climate change. Despite similar limiting physiographic conditions such as lacking outlets and connectivity to outside watersheds, these two terminal basins have different flow regimes, which further define the patterns of aquatic insects and vulnerability to climate change. The differences in flow regimes and aquatic insect assemblages indicate that these two terminal basins were driven by differences in continental climate rather than their ecoregional affiliations. Even though the sample sites were located in the same type of ecoregions, continental level variables drove differential responses in the flow-ecology and predicted responses to climate change. Therefore, when examining similar systems, global and continental-scale effects should be taken into effect for designing large-scale natural resource management of rivers.

Maxillofacial defects compromise appearance and function making individuals incapable of leading a relatively normal life. It is always not possible to rehabilitate all these defects using plastic surgery. Although remarkable advancements have evolved in this field, the patient’s financial constraints make the prosthodontist think about the basic concepts and techniques in the fabrication of these prostheses. Hence an acceptable replacement of such defects becomes a challenge to maxillofacial prosthodontists. Hence an acceptable replacement of such defects becomes a challenge to maxillofacial prosthodontists.

This case report describes a simplified method of fabrication of an orbital silicone prosthesis retained with medical grade adhesive for the rehabilitation of the left eye using inverted anatomic tracing followed by fabrication and processing of the wax pattern. Hence it is the responsibility of the maxillofacial prosthodontist to deliver an esthetically acceptable prosthesis that improves the patient’s morale and help them to lead a normal life.

Solar energy is a clean, abundant, and low-emission renewable energy source. Photovoltaic (PV) technology can convert solar energy into electrical energy; however, it still has a poor output efficiency since high temperatures can lower PV efficiency. Phase Change Materials (PCM) can absorb latent heat, which can be applied to PV as a passive cooling system. In this study, 50 wp PV was treated without and with PCM as a passive cooling system to determine the PV performance. This study compares three PCM types: soy wax, paraffin, and beeswax. Utilizing the PV-PCM panel temperature modeling technique, the inaccuracy in the experimental data was ascertained. According to the simulation, soy wax, paraffin, and beeswax PV panels had average temperatures of 48.6℃, 45.8℃, and 42.6℃, respectively, at an intensity of 1100 W/m2. The experimental results show that PCM beeswax is the best in reducing the working temperature of PV from 60.7℃ to 52.5℃ at an intensity of 1100 W/m2. The results showed that PV with PCM beeswax treatment as a passive cooler could increase the maximum PV output power of 3.04 Watt and the maximum efficiency of PV by 0.94% by lowering the maximum temperature of PV by 8.2℃ compared to PV without a cooling system.

Published: September 2022

Aluminum is one of the most commonly used alloys in industrial applications due to its significant qualities such as resistance to wear, high hardness resistance, and high conductivity. This study will concentrate on the hardness resistance of two dissimilar aluminum alloys at different rotational and travel velocities, where the behavior of the alloys' hardness resistance will be studied after the welding process, from the welding center to the alloys' edges, and this will be done in three areas. Due to temperature changes at the weld in these three separate regions, the first area was at the start of the welding process, the second in the midst of the model, and the third area was at the conclusion of the welding process, to examine the influence of temperature on the hardness resistance. The results showed that increasing the travel velocity of the feed cart and keeping the rotational velocity constant increased the hardness resistance, whereas increasing the rotary tool velocity and keeping the travel velocity of the feeding cart constant decreased the hardness resistance of the two welded alloys. The maximum hardness resistance recorded in the model's welding center (3-3) and its value were more than (49.47 percent) the lowest hardness resistance recorded for all models, which was for the model (7-1).

Published: September 2022

Because air is a clean, renewable source of water that is available everywhere, air extraction is regarded as one of the key means of supplying fresh water. Many researchers have looked into this issue. These investigations may be divided into two major categories. While the second group researches the direct absorption-regeneration of moisture from air, the first group works with the of air. This paper presents and explores previous theoretical and experimental works and study on the topic of extracting pure water from air and using different absorbent substances to absorb water vapor from the atmosphere. The fundamentals and improvements to the topic of pure water extraction and its great benefit were the use of different elements and materials when designing a prototype in the main components of the extraction systems. Drinking water is generated from the air by solar panels using solar energy and heat during the day. It has been discovered that some desiccant materials with good water absorbers, such as calcium chloride and silica gel, may be successfully utilized in the processes of extracting drinking water from ambient air by creating suitable designs. It has been demonstrated that using solar energy may change the high ambient air temperature, a primary cause of water scarcity, into a benefit.
Paradoks fikcji — krytyczny przegląd głównych teorii

Przedmiotem artykułu jest paradoks fikcji. Prezentuję wybrane najważniejsze próby jego wyjaśnienia i rozwiązania. Twierdzę, że ów paradoks wynika z przyjęcia silnego założenia, że do powstania reakcji emocjonalnej niezbędne jest przekonanie o realnym istnieniu czegoś. Przekonanie to wcale nie jest jednak konieczne — można bać się, że p, a równocześnie nie mieć silnego przekonania, że p. Wystarczy posiadać określoną myśl. Bronię tezy, że nasze reakcje emocjonalne zapośredniczone są przez umysł i jego reprezentacyjno-treściowe wyposażenie. Ze względu na skromne piśmiennictwo poświęcone temu tematowi w języku polskim artykuł został napisany w języku rodzimym autora. Artykuł ma zatem charakter edukacyjny i przede wszystkim popularyzacyjny.
W stronę lepszego rozumienia emocji: Wpływ filozofowania z dziećmi na uczenie emocji – przegląd badań rozwojowych
Authors: Janczura Jakub , Karczmarczyk Anna , Gut Arkadiusz , Mirski Robert
Published: September 2022

Niniejszy artykuł podejmuje kwestię roli Filozofii dla Dzieci (P4C) w kontekście rozumienia emocji. Najpierw przedstawiamy początek koncepcji Filozofii dla Dzieci, jako metody pedagogicznej wspierającej umiejętność krytycznego myślenia oraz proces, w jakim przekształciła się w narzędzie badawcze rozwijane w postaci interwencji psychologicznych. Następnie pokazujemy, w jaki sposób narzędzie P4C można zastosować w badaniach rozwojowych dotyczących rozumienia emocji przez dzieci. Argumentujemy, że projekt P4C służy nie tylko budowaniu wiedzy i poprawie zdolności poznawczych, ale sprzyja również kształtowaniu rozumienia sfery emocjonalnej. Pokazujemy, że korzyści z filozofowania w domenie emocji są obserwowane u coraz młodszych dzieci. Zaznaczamy przy tym, że P4C dopiero od niedawna jest wykorzystywana w kontekście wspierania rozwoju emocji, a także w ramach interwencji z udziałem dzieci poniżej wieku szkolnego. Pokazujemy, że jest wynikiem zmian w sposobie pojmowania umysłowości dziecka, które nastąpiły w psychologii rozwojowej w ciągu ostatnich kilkudziesięciu lat.

Authors: Lipnicka Magdalena
Published: September 2022

Celem artykułu jest przedstawienie i porównanie danych odnośnie do zatrudnienia kobiet (w szczególności matek) w niepełnym wymiarze wraz z próbą sformułowania wstępnych uwag dotyczących interpretacji tych danych w Polsce i w Holandii. Zostały postawione takie oto pytania badawcze: Jak wygląda zatrudnienie matek w niepełnym wymiarze? Skąd mogą wynikać różnice pomiędzy Polską a Holandią? Jako metodologię zastosowano analizę porównawczą z wykorzystaniem danych zastanych. Na podstawie badań można wysnuć następujące wnioski: przypadek Holandii i Polski wydaje się potwierdzać, że kontekst społeczny i kulturowy ma duże znaczenie, jeśli chodzi o strategie łączenia roli matki i pracy zawodowej. Matki w Holandii pracują przede wszystkim w niepełnym wymiarze, zaś Polki bardzo rzadko korzystają z takiej możliwości, decydując się albo na pracę w pełnym wymiarze, albo rezygnując z zatrudnienia w ogóle.

Implementing Pesantren (Boarding School)-based Curriculum to Preserve Madrasas in the Post-truth Era in Indonesia
Authors: . Abdul Rohman
Published: September 2022

Madrasas in Indonesia play a crucial role in the country’s national education system. Although, quantitatively, there are a significant number of madrasas in Indonesia, qualitatively, they are facing many problems. Madrasas are considered backwards and marginal institutions, face a lack of public trust, and some have even closed due to a lack of students. All of these are attributed to the factors related to the curriculum of madrasas. A curriculum describes the educational process that will be followed and the profile of graduates that will be produced by the madrasa. The present research is qualitative and explores the sustainability of madrasas by examining the curriculum and learning programs, and habituations at Madrasah Tsanawiyah (MTs) Banat Nahdlatul Ulama Kudus. Data were collected through observation, interviews, and documentation studies. The subjects in this study were teachers, Kiayi, students, graduates, and pesantren administrators, selected by purposive sampling. The results show that madrasas that used a pesantren-based curriculum receive a better response from the society and higher sustainability amind global trends in the post-truth era.

Citation is important in academic writing because it informs the reader about the quality and authority of the information quoted. In-text citations and end-text citations or references are the two types of citations. A reference list provides readers with the information they need to locate and retrieve books cited in a text. End-text references are used to provide this information. Writers can use a variety of citation styles in their writing, such as APA, MLA, Chicago, and others. The goals of this study were to identify the end-text reference forms used in written final project reports and identify the issues using end-text references in written final project reports. The data were collected using an analytic qualitative method, which included the use of a note-taking technique. The research’s data came from a selection of final projects done by English teacher candidates. Identification of end-text reference forms and difficulties with end-text references were used to examine the data. The findings show that (i) the writers primarily use end-text references, as recommended in the department’s final project writing guidelines, and (ii) there are several major issues with the use of end-text references in written reports of selected final projects, including incompleteness, inconsistency in the use of end-text reference styles, and incorrect citation order.

There are many local fast-food restaurants in Yogyakarta. So far, they have survived and grown because they offer low prices. However, to continue to survive it will not be enough to provide low prices because consumers who are sensitive to price tend to switch to other brands if other brands provide lower prices. One way to keep customers loyal is to implement relationship marketing. Therefore, this research investigated the effect of relationship marketing on consumer loyalty.
