Qiblah Angle and Direction of Some Mosques in Zuru Metropolis

A total of 50 mosques (masjids) were randomly sampled in Zuru metropolis, the headquarters of Zuru local government area in Kebbi state, Nigeria, and their qiblah angles taken with modern (scientific) tools notably 3 Islamic apps and one compass, to ascertain the precision of their focus towards makkah. The 3-way analysis revealed the best case scenario of 36%, 6% and 0% of the mosques focused on makkah. It also invariably means 64%, 94% and 100% of the mosques tested were not in the direction towards makkah, by the different approaches used. These results confirm the earlier belief that most of the mosques were not properly focused on the qiblah angle of makkah from Zuru, established at 68.5° in the east-northeast direction from the north. A ‘safe’ range of 67.5 - 79° from north was however found with the tools used. This justifies the use of modern scientific equipments to verify and guide the angular direction of our prayer grounds, as against the hitherto arbitrary dependence of using the sunrise angle as the guide. There’s need for the appropriate authorities to rectify these anomalies, both in row angles already in place, as well as in future construction of mosques, ensuring that they are focused correctly with the prime qiblah angle established, without which prayers conducted will be put in jeopardy.

Результаты исследования уровня развития коммуникативной сферы курсантов - будущих психологов органов внутренних дел

The need to improve the development of communication skills and abilities of psychologists in the educational organization of the Ministry of Internal Affairs of Russia is due to the low level of development of the communicative sphere of the personality of graduates. This is confirmed by the empirical research data presented in the article. At the same time, there are no tools for monitoring the development of this area and taking into account the personality characteristics of students in the implementation of the relevant disciplines of the educational program. As practice shows, the educational process is traditionally implemented within the framework of several basic disciplines aimed at developing competencies related to the communicative sphere of personality. At the same time, the initial level of development of communicative abilities and personality traits of students are not taken into account. In addition, the assessment of the development of the graduate's communicative sphere based on the results of the implementation of the relevant disciplines is not carried out. The article proposes an approach to the use of the developed universal scientific and methodological apparatus aimed at the development of psychologists in the process of their professional training by changing their communicative sphere, taking into account the characteristics of their personality.

The SEMinal impact of contemporary science: integrated authentic science design and students’ self-efficacy and career aspirations

ABSTRACT Authentic science learning has a significant potential for contributing to students’ self-efficacy (SE) and science career aspirations (SCA) by introducing contemporary science. However, the design of authentic learning remains challenging due to the elusive and subjective nature of experiencing authenticity and the interdisciplinarity and complexity of contemporary science. This study aimed to transform these challenges into opportunities by integrating theoretical frameworks of authentic design with a unique setting, including: (a) authentic pedagogy highlighting social experiences, (b) authentic scientific equipment including hands-on operation of a scanning electron microscope (SEM) situated in a research institute, (c) contemporary science theme (biomineralization). This integrated design was investigated by collecting data from 70 secondary science students on their perceived-authenticity, SE, and SCA using pre–post Likert-type questionnaires. After discovering that authenticity was intensely perceived, we used inferential statistics to examine the relationships between different authentic aspects related to both hard and soft science skills and SE and SCA. We identified a significant connection between students’ experience of acquiring authentic knowledge (i.e. hard skills) and their SCA, as well as between the social experience (i.e. soft skills) and students’ SE. This study contributes to understanding the design and impact of authentic science activities in research institutes.

Monitoring of suspended matter in the Dnipro River within Zaporizhzhia city, the main trends of 2022

The article presents the results of monitoring observations on the temporal distribution of the qualitative and quantitative components of the Dnipro River suspended matter within Zaporizhzhia city. The research on the territory of this powerful industrial center of Ukraine with a developed metallurgical complex was carried out from 2015 up to 2019 and from the end of 2021 to the present time. The main task of the research was determining the distribution of iron and a group of heavy metals of anthropogenic origin in the composition of the river suspension, and identifying the connections of their concentrations and forms with the natural conditions of the region. Sedimentary matter from the water flows of Dnipro River within research area was sampled once per month using sedimentary traps developed by authors. The methods of electron microscopy (with microprobe analysis) and laser diffraction analysis were used to study the suspension granulometric and chemical composition in the Center for Shared Use of Scientific Equipment of the IGS NASU. SEM studies were carried using scanning electron microscope SEM JEOL-6490 LV (Jeol Ltd., Japan) with an energy dispersive spectrometer of the X-ray microanalysis system INCA Energy+ (Oxford Instruments plc., Great Britain). Particle size analysis was determined using the laser particle size analyzer Mastersizer 2000 with a Hydro 2000S wet dispersion module (Malvern Ins. Ltd, UK).The study results of the samples taken in the first year of hostilities in Ukraine revealed a number of features which were not observed in the previous series of studies. Those peculiarities are the following ones: reduction in the intensity of sedimentary matter accumulation; decrease of technogenic components in the suspension content (in particular, the amount of ferrous metals, changes in the ratio of condensed and dispersed iron particles of silt size, as well as the component composition of fragments of alloys of non-ferrous and ferrous metals). The obtained results may indicate the sensitivity of the component composition of the suspension to changes in the external environment in general, as well as the significant impact of the anthropogenic component on the distribution of iron in suspended matter.

Nonlinear dynamics of wing-like structures using a momentum subspace-based Koiter-Newton reduction

Cantilevers find a wide range of applications in the design of scientific equipment and large-scale engineering structures such as aircraft wings. Analysis techniques based on linearization approximations are unable to capture the large amplitude oscillation behaviour of such structures and thus, necessitates development of dedicated nonlinear methods. In this work, the recent developments in the Koiter-Newton model reduction method are utilized to obtain nonlinear reduced order models (ROMs) from full finite element structural models in order to simulate large amplitude dynamics of cantilevers. The method describes a nonlinear system of governing equations comprising quadratic and cubic terms which are obtained as higher order derivatives of the in-plane strain energy. To ensure that the large rotations in cantilevers and the resultant foreshortening effect is also accounted for, a ROM updating algorithm is adopted where the ROM parameters are varied with the structural deflections. Linear eigenmodes of the structure are utilized to form the reduction subspace. To validate the methodology, the ROM solution is compared against experimental results and a convergence study is conducted to identify the number of modes needed to replicate the nonlinear response. Finally, a composite wingbox structure is considered for which time domain simulations are conducted and frequency response curves, obtained through a frequency sweep, are presented.

Innovation and interculturalism are important features of future teachers' training in modern society

The processes of globalization, the formation of a post-industrial society, the European integration aspirations of Ukraine and the integration of the Ukrainian education system into the European educational space set the pedagogical science the task of bringing the traditional scientific apparatus into line with the system of pedagogical concepts generally accepted in Europe. The developing Ukrainian society needs highly educated people with appropriate professional and general competences who can independently make responsible decisions in a choice situation, predicting their possible consequences, capable of cooperation, distinguished by mobility, dynamism, constructiveness, a developed sense of responsibility for the fate of the country. Decisions and programs aimed at the implementation of scientific achievements, civilizational and cultural trends are implemented through the activities of subjects who perceive them. In this connection, the level of requirements of modern society for the activity and training of teachers in higher education institutions is increasing. Strengthening the integrative and cultural status of education dictates the need to train pedagogical staff capable of realizing its cultural focus. The needs of modern educational practice create the need for cross-cultural training of the future teacher of the Ukrainian language and literature, who not only acts as a mediator between the student and culture, but also contributes to the formation of the young generation's readiness to live and act in an open intercultural space of general civilization.

The fourth generation of academic Kazakh grammar

The article discusses the issue of compiling large grammatical works, including academic grammars. In particular, answers are sought for such questions as the following: What is the scientific character (style) of compiling fundamental grammatical works? What should their scientific apparatus, their design and structure look like? What research methods should be used? What is their target audience? In order to achieve this purpose, we carried out a comparison of academic grammars originating in the Soviet Union and those fundamental, voluminous grammatical works compiled according to the European-American model. The experience of compiling grammatical editions in Turkic languages has also been taken into account. The ideas obtained as a result were used in compiling the next academic grammar of the Kazakh language. This article was written with the objective of sharing the experience and elaborating on the results of the comparison. It has been found out that fundamental grammatical works have their own scientific character (this concerns the Soviet school): academic grammars are written on the normative and descriptive basis, i.e. scientific descriptions must be accompanied by a normative differentiation. The structure is directly linked to the levels of language which the editorial board have chosen as the object of study (lexis, phonetics, word building, morphology and syntax). There are consistency and moderation in designing grammatical works as well. Research material and examples are taken from literary samples. These principles are based on the fact that academic grammars are oriented to scientific and educational community. At the same time, as European and American fundamental grammars are compiled for the general scientific community, the aforementioned academic principles may not be followed. Since fundamental grammatical works are not compiled very often (once in 20–30 years), such studies are not frequent either. The grammars created in the Soviet period have not been revised fully yet. It is specifically important to revise academic grammars, as they need to document and standardize the new knowledge in the field of language. The issue of revising the academic grammar of the Kazakh language has been brought into the spotlight, and in 2022, the new generation of the grammar was prepared. For this reason, the conclusions of the article and the experience obtained while developing the new generation of the “Kazakh Grammar” may become useful while compiling new fundamental grammatical works.

Research on the influence of gas types on the pumping performance of dry Roots vacuum pump

With the advancement of technology, dry vacuum pumps are widely used in aerospace, semiconductor, chemical and pharmaceutical and scientific equipment due to their clean and oil-free advantages. Usually the pumped medium contains different types of gases, dry Roots vacuum pumps are prone to unstable performance, which can adversely affect process efficiency. To investigate the influence of gas types on the pumping performance of Roots vacuum pump, experimental research was conducted on self-designed dry vacuum pump theoretical verification platform and test pump. The gas mixture of 70 % nitrogen and 30 % helium was tested using 2-lobe, 3-lobe and 5-lobe Roots while numerical simulations were conducted on air, nitrogen, helium and hydrogen. The experimental results indicate that the gas type affects the pumping speed of the Roots pump. In addition, the numerical simulation results show that hydrogen has the greatest influence on the pumping performance of the Roots; the pumping speed shows ‘W’ type fluctuation in one cycle when the 3-lobe Roots pumps hydrogen. The pumping speed of the 5-lobe Roots is most affected by changes in gas types. This study is of guiding significance for the application and design of dry Roots vacuum pumps in different process environments.

OpenHW3 – An open-source, low-cost temperature-controlled orbital shaker

The current lack of standardized testing methods to assess the binding isotherms of ions in cement and concrete research leads to uncontrolled variability in these results. In this study, an open-source and low-cost apparatus, named OpenHW3, is proposed to accurately measure the binding isotherms of ions in various cementitious material systems. OpenHW3 provides two main options, a temperature-controlled orbital shaker, as well as an option to retrofit a commercial orbital shaker for temperature control. The effectiveness of these device options is validated via comparison with conventional binding isotherms experiments. The binding isotherm results were comparable to conventional Waterbath shakers, while providing more reliable results compared to horizontal commercial shakers. It also provided accurate temperature control between 25 °C and 75 °C. The results here are critical for allowing open access to scientific equipment, and providing high-quality binding isotherm data for reliable service life models of urban infrastructure assets throughout the world.

The Effects of Integrated Proprioception Development Strategies in Increasing the Psycho-Neuro-Motor Level of Children

This research aims to evaluate the improvement of proprioception capacity in 24 male subjects, aged 10 years, by applying an intervention strategy and proposing a specific competence within the physical education school program for the 4th grade in Romania. An experimental group (EG, n=12) underwent an ameliorative intervention for 14 weeks, having two lessons per week, while a control group (CG, n=12) followed the usual football training program at the club sport. Both EG and CG subjects were evaluated, under similar conditions, using four tests: Body Sway, Flamingo, March in place – MIP and Circle, using scientific equipment OptoJump Next and GYko Microgate. The statistical analysis compared the results of the two groups, using the Kolmogorov Smirnov test to verify the normality of the distributions, and to verify the significance of the statistical differences, the Independent T-test and the Mann Whitney U-test were used. The results revealed statistically significant differences in three of the four applied tests, confirming the general efficiency of the experimental program. These findings support the possibility of optimizing the contents of the school physical education program to support the development of proprioception and body awareness in primary school children. The use of high-tech equipment, such as GyKo Microgate and OptoJump Next, can provide standardized data on neural processing of sensory information, thus contributing to a more accurate and efficient approach to school physical education.

Is logic useful for doing Philosophy?

Providing some basic arguments and a historical context, I introduce the special volume What can we do in Philosophy using Logic? In this introduction, I discuss whether logic is useful for understanding, evaluating or building arguments in philosophy. I argue that, although there has been research supporting the idea that logic can serve as a philosophical instrument, this has not shown completely its utility. This is the reason I offer to discuss the importance of logic in philosophy, trying to show that philosophers employ logic when they work with arguments and also obtain worth benefits by applying it.

An Appraisal Of Large-Scale Particle Tracking With Uncrewed Aerial Vehicles

Camera technology is rapidly enhancing within the last years, which led to the availability of sophisticated technical features within consumer cameras, that could only be found in scientific set-ups earlier. The present work explores the possibilities of utilizing the potentials of commercially-available camera drones as moving cameras for large-scale particle tracking velocimetry. We made use of the glare-point particle tracking approach introduced by Kaiser & Rival (2023), where only a single camera and natural illumination, e.g. the sun, could be used. The set-up demonstrated full suitability for large volumes in the order of 10-100 m³. The frame-to-frame camera movement, caused by the slight movement of the drone could be quantified and corrected by an imaged-based approach. The calibration strategy could be simplified due to the fixed set-up in the camera drone. The limits introduced through the tracer size and uncertainty caused by the glare-point approach are discussed accordingly. For the presented magnification and camera set-up given by the DJI Mini 3 pro, the limit in height can be determined when the two most dominant glare points collapse to one, which happened well above 10 m for the present set-up. The equipment together with the glare-point particle tracking approach is best suited for flow information extraction at large-scale facilities or difficult accessible terrain, where the current set-up could depict its strengths.
