Authors: Issenov Sultanbek , Antipov Pyotr , Koshumbayev Marat , Issabekov Dauren 
Published: March 2024

The object of research is a wind generator with counter-rotating blades. A special feature of this design is the presence of two wind wheels that rotate in opposite directions. Wind wheels are on the same axis, between them there is a certain distance, which is determined based on research data. The problem of modern wind power is the low range of operating wind speeds, weak generation at low wind speeds. The upper speed limit is 25 m/s, exceeding which leads to breakdowns of various units of the wind station, especially this affects the integrity of the blades, rupture of the wind wheel, cracking of the metal parts of the bearings and their fasteners. The wind turbine presented in the article allows to achieve an increase in the generation of electric energy by 50–70 %. This is achieved by increasing the relative rotational speed of the rotor relative to the stator. Therefore, even at low speeds, the rotor speed relative to the stator increases, which leads to an increase in power generation. The design of the device includes: two wind wheels, one transmits its rotation to the stator, the second to the rotor axis, a metal base, a current collector mechanism. For conducting the research, an experimental model and a semi-industrial installation were used. Results studies have confirmed the theoretical increase in the generation of electrical energy by this design. The peculiarity of the obtained results is connected with the determination of the distance between two wind wheels, the optimal distance between them corresponds to the maximum energy generation. A distinctive feature of the results obtained can be considered an increase in the number of blades on the second wind wheel

Purpose of the study. Is to describe the experience of creating a collection of biological images of tumor tissues and biomaterials, which are control samples, for scientific research in morphology and molecular oncology.Materials and methods. We studied the molecular markers of cell cycle regulation, apoptosis, oncogenesis and angiogenesis, the expression of proteins that regulate inflammation and tumor infiltrate cells in biocollections of verified tumors of common localizations: e. g. thyroid cancer, colorectal cancer, breast cancer, prostate adenocarcinoma, endometrioid adenocarcinoma. Also, tissue fragments with normal structure or non-tumor pathology (autoimmune thyroiditis, adenomatous and thyrotoxic goiter, benign formations of the colon, fibrocystic disease of the mammary glands, benign prostatic hyperplasia, endometrial hyperplasia) were used as control samples or comparison groups. The total number of tissue samples is n = 7000.Results. It is reasonable to gather the collection in a pathomorphological laboratory according to the profile of the medical institutions, which has a sufficient volume of incoming target material and specialized morphologists to verify tumors of a given localization. It is necessary to consider the regional and ethnic specifics of the population, which determines the sampling and mutational load. The laboratory must initiate an addition to the informed consent of patients about the possibility of conducting morphological and molecular genetic studies for scientific purposes and publishing their results in a depersonalized form for the development of new elaborations, when signing the contracts with legal entities and individuals and when serving patients within an institution. When working with biocollections, it has to consider having registers of tissue biomaterials of target disorder groups of main localizations with downloading by year from an accessible information system, consider external factors affecting the database (changes in clinical recommendations and classifications, the population of patients served, pandemics and other significant events). The standard of the preanalytical stage, data collection, development of protocols for analytical molecular genetic studies and their evaluation, the utilization of the capabilities of working with reagents for scientific tasks and modeling experiments on laboratory animals are crucial.Conclusion. The formed biocollection made it possible to carry out a number of initiative and funded domestic and international scientific projects at the request of clinicians and fundamental researchers, as well as to improve the quality standards of morphological and molecular genetic oncology diagnostics. Biobanking makes the pathological archive more accessible for review and use, significantly expanding its scientific and practical potential. Scientific and medical research do not conflict and can be used within the same laboratory.

Purpose of the study. Analytical review and analysis of available literature on texture analysis of computed tomgraphy (CT) and magnetic resonance imaging (MRI) in noninvasive diagnosis of ICC and correlation with molecular genetic features and tumor immunophenotype.Materials and methods. The scientific publications and clinical guidelines in the information- analytical systems PubMed, Scopus for 2012–2022 were carried out using the keywords: "mri", "radiomics", "texture analysis", "radiogenomics", "intrahepatic cholangiocarcinoma", "molecular". 49 articles were selected for analysis after excluding studies dealing with technical aspects of radiomics and describing individual clinical observations.Results. The presented review demonstrated the broad possibilities and prospects of application of CT and MRI texture analysis in the study of cholangiocellular cancer, including the first results in the study of molecular features (signatures) of this tumor. Correlation of texture features with the expression of immunotherapy target genes KRAS/NRAS/BRAF as well as IDH1/2 mutation was shown. Texture scores were the predominant independent predictor of microvascular invasion, which was a major independent risk factor for postoperative recurrence.Conclusion. The use of texture analysis undoubtedly demonstrates promising possibilities both in noninvasive assessment of the HCC histological differentiation grade, as well as in differential diagnosis with hepatocellular carcinoma, metastases, and requires further study for systematization and standardization of the obtained data.

Published: March 2024

The elongated left lobe of the liver (saddle liver, saber liver, beaver tail liver, beaver lobe) is one of the types of variant liver anatomy, characterized by the fact that the left lobe extends far beyond the midline of the body, and can come into contact with the spleen and even go above it. Due to the fact that the elongated left lobe of the liver is more often susceptible to injury and, in some cases, can imitate a subcapsular hematoma of the spleen, it seems important to increase the awareness among doctors of various specialties about the variety of morphological variations in the structure of the liver, in particular about the elongated left lobe of the liver, to unify approaches to the description and establish uniformity of wording to designate this feature of the anatomical structure of the left lobe of the liver, which will reduce the risk of diagnostic errors and errors during surgical interventions, especially in cases of blunt abdominal trauma.The article presents clinical cases with ultrasound examination of 10 patients of different ages (from 1 month to 38 years) and gender with a newly diagnosed anomaly in the structure of the left lobe of the liver, i.e an elongated left lobe. An analysis of national and foreign literature sources containing reports on various morphological variants of the liver structure and the frequency of their occurrence was carried out. Ultrasound signs were proposed to describe the elongated left lobe of the liver. The features of the ultrasound examination technique for the elongated left lobe of the liver in children older than one year are described. The variety of formulations used by different authors when describing this variant of the anatomical structure of the liver was studied.

Published: March 2024

This study aims to investigate how consumer behaviour in Malaysia is influenced by the characteristics of social media influencers who shape consumers' perceptions of drone quality and brand awareness. The research framework on brand recognition, brand loyalty and brand image were adopted from the previous literature. The Malaysian Gen-Z population with disposable income and who use social media are the target of this study. They were users of social media such as Facebook, Instagram, WhatsApp and email. Convenience sampling was used to deliver online surveys. A total of 230 samples were successfully collected. The findings indicate that brand awareness and perceived quality are positively and significantly impacted by social media influencers while brand image is positively and significantly impacted by perceived quality but not brand awareness. Perceived quality acts as a mediator between social media influencers and brand image. An analysis of prior research frameworks and studies was conducted to assess the relationship between drone brand image and influencers. Drone research has not been thoroughly investigated. Therefore, this will address some knowledge gaps. A thorough comprehension of the principles of perceived quality and brand awareness is necessary in order to better comprehend the role that social media influencers can play in marketing consumer drone brands.

The goal of this study is to investigate the impact that online celebrities had and still have on Malaysian customers' intents and purchasing behaviours. The use and gratification theory, the source credibility model and the source attractiveness model are the three theoretical frameworks that form the foundation of this study. These models provide the foundation for this research. 384 respondents who are older than 18 and use social media provided answers to the questionnaire which takes the form of an online survey. SPSS software (Statistical Package for the Social Sciences) was used for the data analysis and regression analysis was chosen as the method to use in order to establish the significance of hypotheses based on the data collected in order to determine whether or not the data collected supported the hypotheses. This study found that in order for social media celebrities to successfully influence consumers' intentions to make a purchase through the internet, they need to demonstrate that they are reliable, appealing and knowledgeable. In the context of Malaysia, these are the characteristics that are particularly important in determining whether or not a customer will make a purchase over the internet.

Authors: Kamali Mohadeseh , Sarvtin Mehdi Taheri 
Published: March 2024

Background and Aims: Fungal spores constitute a significant portion of primary biological aerosol particles, and large amounts have been identified in the air. They are present in the atmosphere throughout the year, and their concentration varies due to meteorological factors such as temperature, relative humidity, location, construction conditions, and vegetation. Exposure to airborne fungi has been linked with diseases such as allergic respiratory symptoms, rhinitis, asthma, and various infections. This study investigates the diversity and distribution of airborne fungal spores in Jiroft City, located in the southern region of Iran.
Materials and Methods: Airborne fungal composition was sampled from indoor, outdoor, and hospital air using the sedimentation plate method. Grown fungi were identified using standard mycological techniques, including determining macroscopic and microscopic characteristics.
Results: A total of 230 colonies belonging to 11 genera of fungi were isolated from all culture media. Fungi were isolated from 53 (80.3%) samples. The highest and lowest percent of positive samples were found in outdoor (100%) and hospital (64.3%) air samples, respectively. Cladosporium (43.9%) and Aspergillus (36.4%) were the most common fungi isolated from the samples. Rhodotorula, Syncephalastrum, Paecilomyces, Mucor, and Acremonium were the least isolated fungi (1.5%).
Conclusion: This study showed the difference in the diversity and distribution of fungi in different environments. Cladosporium and Aspergillus were the most common fungi isolated, which need to be considered due to their ability to cause various diseases.
An exploratory study of University Students’ Lived Experiences and Memories of Childhood Abuse.
Authors: Lucas Paskas Wagana 
Published: March 2024

Child abuse is a serious and devastating global problem. In Tanzania this problem exists in a variety of forms and is deeply rooted in cultural, educational and social practices, often mixed with, and difficult to distinguish from normal measures of correcting and disciplining children. This study is undertaken to describe the patterns of child abuse (physical, emotional and sexual) as experienced by university students in Tanzania in their childhood. The study also aims at obtaining deeper understanding of the different types of perpetrators who interacted with, and inflicted abuse to children in the family and community at large.
Data comes from a representative sample drawn from university students (n=470) in one university in Tanzania in March 2019. Structured questionnaires were used to collect data. Descriptive statistics were used to analyze data.
The results show multiple experiences of physical, emotional and sexual child abuse for both male and female students. The findings also indicate that family members, teachers, peers, and motor-cycle drivers were involved in the abuse of children consistent with similar studies which categorize such groups of people as perpetrators of child abuse (Moore et al, 2007; UNICEF Tanzania, 2011; Kisanga, 2012; McCrann, 2017)
The study recommends that behaviors of child abuse be given due attention to ensure proper care, normal development and guarantee protection of children. The study also highlights the significance of engaging university students on intervention programs to counteract the negative effects of child abuse during adulthood.
Biological Movements as Objects of Natural Science (In memory of Michael Turvey, February 14, 1942 - August 12, 2023)
Authors: Feldman Anatol 
Published: March 2024

Michael Turvey was a great scientist, encyclopedist, fine lecturer, and, together with his wife and colleague Claudia Carello a wonderful friend of many. Mike Turvey was able to educate the next generation of students and influence the thinking of many outstanding researchers by focusing on a multidisciplinary approach to ecological psychology in which organisms directly perceive sensory stimuli and evaluate them depending on actions they can accomplish in the environment (Gibson 1968). This, “affordance principle” is applied to all biological kingdoms from a single cell amoeba to multi-celled organisms. Some other essential ideas in behavioral neuroscience advanced by Turvey are considered.

Published: March 2024

This study examined the psychological impact of social media on Nigerian teenagers looking at how social media posts and tweets (messages) influence their perceptions towards migrating abroad. A survey research method was adopted to investigate the problem in its natural setting. Four secondary schools (SSs) within Edo North, Edo State, Nigeria were randomly selected from 56 government-owned SSs for the study. A questionnaire was used as a data collection instrument to obtain respondents' views (data) which was later analysed using SPSS. Spearman correlation and Pearson's R were used to measure the two hypotheses symmetrically. The chi-square was then used to test the results. According to their opinions (data collected), the findings of the study revealed that Nigerian teenagers of school age have access to social media, prefer text, video and audio kinds of information and mostly prefer Facebook to other social media networking sites. After analysing the tested hypotheses, the researcher concludes that there is a significant relationship between social media messages and Nigerian teenagers’ desire to travel abroad. Hence, social media messages or information affect their mental construct negatively which could be compared to mental slavery and they made some recommendations that would assist in mitigating these impacts.
