Authors: Toktarbek M. , Seitimova G.A. , Burasheva G.Sh.
Published: October 2024

Kazakhstan is rich in medicinal plants, so it needs to be studied. Ten species of the Petrosimonia  belonging to the Chenopodiaceae family are growing in Kazakhstan. These plants have been adapted to harsh climatic conditions in the country’s salty, saline, and desert areas. Petrosimonia plants are a new species that has not been fully studied. Chinese scientists studied Petrosimonia sibirica species and found that the plant contains alkaloids, steroids, terpenes, flavonoids, and phenolic acids and has antibacterial activity (Wen, 2015; Ying, 2016). The qualitative and quantitative compositions of biologically active substances in P. sibirica, P. Glaucescens, P. triandra, and P. brachiata growing in Kazakhstan were studied. To prepare phytopreparations from P. Sibirica, P. Glaucescens and P. triandra plants were extracted using the classical maceration method, and individual representatives of biologically active compounds were isolated (Toktarbek, 2021; Seitimova, 2022). In this study, a phytochemical study of P. brachiata was conducted. The method for obtaining biologically active complexes with high efficiency was optimised by using supercritical fluid and ultrasonic extraction methods. These methods have a short extraction time, can be carried out at room temperature, are cost effective, and are a modern green chemical approach. Using supercritical fluid CO2 extraction (180 bar, 2 hours), the plant was purified from lipophilic substances. Further, a biologically active complex was obtained by pouring 70% ethanol-water solvent into the plant raw material and performing ultrasound extraction. The obtained complex was analysed by thin-layer chromatography using different organic solvent systems. Based on our analysis, steroids, terpenes, phenolic acids, and flavonoid glycosides were found in the extract. Hexane and ethyl acetate fractions were obtained as a result of liquid-liquid extraction of the extract using organic solvents. Stigmasterol 3-O-β-D-galactopyranoside, isovanillic acid, quercetin 3-O-β-D-glucopyranoside, and isorhamnetin 3-O-α-L-rhamnopyranoside  were isolated by washing the hexane and ethyl acetate fractions in a silica gel column with an organic solvent system. The isolated compounds will be tested for biological activity.

Authors: Spiesecke Paul , Thiemann Janine , Conen Patrick , Clevert Dirk-André
Published: October 2024

Ultrasound is the most used interdisciplinary imaging technique in clinical routine for assessment of renal pathologies. This includes the monitoring of cystic renal lesions, which can be classified as non-complicated or complicated and by means of occurrence as solitary or multifocal lesions. The Bosniak-classification (I–IV) classifies renal cysts in 5 different categories and is used for decisions of further clinical treatment. This classification was developed for computed tomography and has been adopted for magnetic resonance imaging as well as contrast-enhanced ultrasound. In the following review article, cystic kidney lesions and their differentiation using contrast-enhanced ultrasound are presented and an overview of the therapy options is given. In interventional procedures, CEUS can make a valuable contribution in histological sampling, reduce radiation exposure and, under certain circumstances, the number of interventions for the patient.

Published: October 2024

The alkali and alkaline earth metals such as potassium, sodium, barium and strontium are generally used as oxidizer in fireworks. The arbitrary use of these chemicals in fireworks is an acute issue responsible for higher emissions. Hence, efforts are underway to monitor these chemicals in fireworks. This work reports the precise determination of potassium and sodium in fireworks samples by flame photometry. The average deviation by flame photometry analysis was 7 to 8 % and 3 to 4 % for potassium and sodium, respectively, when the concentration of the respective metal nitrates in fireworks composition was less than 50%. The effect of different components in fireworks mixture, such as nitrate and metal precursor, were also studied to understand their impact on results. A brief study in terms of limit of detection (LOD), limit of quantification (LOQ) and dynamic range was also performed, which showed 0.42 and 3.26 mg/L as LOD and 1.29 and 9.88 mg L-1 as LOQ for the analysis of sodium and potassium, respectively. In summary, the study proved the prospective of flame photometry for determining sodium and potassium in fireworks samples.

Published: October 2024

Chronic intestinal granulomatous disease is a disorder that directly compromises the entire immune system. The estimated incidence is one in a million inhabitants. Among the associated risk factors, the presence of chronic and recurrent infections stands out. In the present case, it is a 39-year-old female patient with a history of intestinal obstruction and endometriosis, who presents abdominal pain in the left abdomen and recurrent abdominal pain without an identifiable cause. Laboratory tests revealed leukocytosis and mild neutrophilia. The tomography showed intestinal dilation at the jejunoileal level without transition zones, and the serological tests were negative. Exploratory laparoscopy was performed and the presence of tumor implants was found in the omentum, extending to the abdominal, uterine, intestinal, and peritoneal regions, as well as sallow fluid at the abdominal level. Tumor markers are normal. Histopathology details fungal colonization with eosinophilic necrosis and presence of granulomas, negative immunohistochemistry for Aspergillus and negative Lowestein-jensen culture. Antifungal and antituberculous treatment was started, with a decrease in symptoms and improvement in the clinical picture.

Published: October 2024

Nasal obstruction is characterized by insufficient airflow and increased resistance in the nasal cavities, affecting patients’ quality of life and sleep. This study aims to compare the efficacy of medical and surgical treatment in patients with Nasal obstruction, using subjective evaluations (NOSE and VAS scales) and objective evaluations (active anterior rhinomanometry). This is an experimental and prospective longitudinal study conducted at the Hospital de Clínicas, Paraguay. Forty patients with Nasal obstruction were included, divided into medical treatment (nasal corticosteroids) and surgical treatment (turbinoplasty, septoplasty, or both) groups. Pre- and post-treatment evaluations were performed using the NOSE and VAS scales, and active anterior rhinomanometry. The sample included 52.5% men and 47.5% women, with an average age of 32.18±11.59 years. The main cause of Nasal obstruction was chronic rhinitis (62.5%). Treatments showed significant improvements in subjective and objective evaluations. In the medical group, VAS improved by 2.63 points in women and 2.00 in men, while the surgical group showed more pronounced improvements. The NOSE also showed significant reductions, especially in patients undergoing combined turbinoplasty and septoplasty. Active anterior rhinomanometry reflected an increase in overall nasal flow in all treated groups. Both medical and surgical treatments are effective in improving Nasal obstruction, with greater benefits observed in surgical treatments. Subjective and objective evaluations are valuable and complementary tools for assessing treatment in patients with Nasal obstruction. These results highlight the importance of a comprehensive evaluation in the management of Nasal obstruction.

Published: October 2024

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder characterized by hormonal imbalances, metabolic dysregulation, and reproductive abnormalities. This study aims to elucidate the significance of PCOS markers and their mechanisms while outlining the methodology employed. A comprehensive literature review was conducted from 2020 to 2023 using databases like PubMed, ScienceDirect, EMBASE, and Google Scholar. Key search terms included "pathophysiology," "pathogenesis," "PCOS," "marker," and "biomarker," aligned with the PICOT criteria. After removing duplicates, articles underwent a two-phase screening process based on predefined inclusion criteria. Additionally, a marker mechanism flowchart was created using the Biorender application. Results highlighted the pivotal role of various markers in understanding PCOS pathophysiology and guiding clinical management. Anthropometric, visual, metabolic, inflammatory, endocrine, and oxidative stress markers were analyzed for their diagnostic, prognostic, and therapeutic implications in PCOS. The study underscores the importance of marker interactions in personalized PCOS management. Limitations in marker interpretation warrant further research to refine diagnostic accuracy and optimize therapeutic interventions. Integrating marker mechanisms enhances understanding of PCOS heterogeneity and informs targeted treatment approaches tailored to individual phenotypic variations.

The issue of punishment and its appointment is very relevant both in the country and in other states. Here we are talking about the social consequences that can be achieved in criminal law when imposing and applying punishment to persons found guilty of committing a criminal offense. In recent years, Kazakhstan's criminal policy has been paying more attention to combating serious and especially serious crimes, facilitating criminal liability for less serious and moderate crimes. That is, in the first case, various grounds for the application of punishment for crimes not related to isolation from society are considered, and in the second - the possibility of appropriate impact on convicts of punishments in the form of imprisonment. As already noted, in the article, the authors assess how often types of punishments are considered in criminal sanctions, based on the general grounds for imposing punishment on the guilty person in order to achieve the purpose of punishment. At the same time, the relevance of this issue indicates that there are difficulties in imposing punishment, taking into account aggravating and mitigating circumstances in accordance with criminal law. In the article, the authors provide recommendations on mitigating circumstances. The purpose of the research work is to identify contradictions that arise in law enforcement practice when imposing punishment. The paper uses formal logical, historical and comparative methods.

Published: October 2024

Since the early 1990s, Kazakhstan has been actively attracting foreign direct investment (FDI), concluding various investment agreements, and enacting legislation to encourage this process. To encourage foreign capital, as well as the need to settle investment disputes, in 2004 the Republic of Kazakhstan ratified the Convention on the Settlement of Investment Disputes between States and Nationals of Other States, March 18, 1965. Washington, March 18, 1965. As follows from the Resolution of the Government of the Republic of Kazakhstan dated July 15, 2022 "On Approval of the Concept of Investment Policy of the Republic of Kazakhstan until 2026" for the period 2010-2020 the level of foreign direct investment amounted to 250 billion USD. According to this Resolution, the level of re-investment of foreign capital in our country's economy for the period 2005-2020 remains at a low level of 15 percent, while the world average is 30-35 percent. The creation of favorable investment conditions, the promotion and protection of investors' interests and the development of mechanisms to compensate for losses in the event of nationalization or expropriation play a key role in attracting foreign investment. Thus, from the perspective of foreign investors, one of the problematic aspects of the country's investment attractiveness is the lack of confidence in the judicial system, including the enforcement of arbitration awards within the judicial system of the Republic of Kazakhstan. In the opinion of the author, the practical significance of the article lies in the development of proposals for the improvement of investment attractiveness through the elimination of contradictions in the legal acts of the Republic of Kazakhstan in the settlement and resolution of investment disputes within the framework of obligations under the Convention of 18 March 1965.

Published: October 2024

This paper aims to familiarise the readers with the motivations and pedagogical principles behind the outcomes of the ‘SCALED – Supporting Content and Language Learning Across Diversity’ project and with the outcomes themselves. These include an open online course for initial teacher training and continuing professional development of language teachers, accompanied by a methodological guide and a report on good practices in inclusive language education and inclusive foreign language teacher training. The SCALED project addresses the needs of both the academic and school communities, aiding educa- tors in proactively eliminating existing and potential barriers to language learning. It incorporates empirically validated models and approaches, such as Universal Design for Learning (UDL) and the integration of indi- vidual accommodations and adjustments in learning and assessment conditions. The project seeks to advance fairness and counter discrimination and marginalization by fostering inclusive practices in teacher training and language education via enhanced accessibility. Accessible language learning environments can empower individuals with diverse needs, including special educational needs, and enable them to unleash their abilities and potential. Accessibility constitutes a leading theme that transpires in all SCALED course modules and materials, from accessible instruction and assessment, through accessible and usable digital language materials (docu- ments and multimedia) and online learning platforms to accessible and supportive language learning environ- ments (e.g. assistive technology) for learners with special educational needs resulting from dyslexia, ADHD, autism, blindness and visual impairments, and diverse cultural and language backgrounds.

Authors: R Risuhendi , Fachrudin Hilma Tamiami , Bukit Rina
Published: October 2024

This research aims to analyze the factors that influence the rental value of shophouses in Medan Petisah District, Medan City. The difference in shophouse rental prices is caused by increasingly expensive land prices, which are influenced by busy locations and the presence of new buildings. The Petisah area has experienced rapid development in recent years, causing a significant increase in land prices. This land issue is very important considering the increasing need for regional development. This research uses a market approach to determine the rental value of shophouses by analyzing the factors of building area, rights (certificates), building age, location, road width and parking area simultaneously and partially on the rental value of shophouses. This type of research is quantitative/associative/correlational with inferential statistical data analysis. The population of this study was all shophouses in Medan Petisah District, totaling 456 shophouses, with a sample of 82 shophouses. Data is processed using multiple regression analysis. The research results show that simultaneously, all independent variables have a significant effect on the rental value of shophouses. Partially, the variables of building area, rights (certificate), building age and parking area have a significant effect, while the variables of location and road width have no significant effect. Based on the regression coefficient value, the variables building area, rights (certificate), building age, and parking area have a positive and significant influence on shophouse rental values ​​in Medan Petisah District, Medan City

Published: October 2024

The article examines the payment systems used in the world and in Ukraine, their features and components, existing varieties. It has been proven that payment systems based on electronic money include: payment systems based on smart cards; softwarebased payment systems operating on the Internet; payment systems based on mobile communication networks. The existing classifications of payment systems are given according to various characteristics: by the method of execution, by the type of operation, by the form of ownership, by the territory of operation, by the degree of residency of the participants, by the volume of payments made, etc. The article, based on its own long-term experience of working with various electronic payment systems, offers its own classification of payment systems by the scope of coverage: a) global payment systems; b) local (national) payment systems. The main global payment systems of the world and local payment systems of the United States, Canada, Great Britain, the countries of the European Union and Ukraine are indicated. A general scheme of the entire system of electronic payments has been built. The mechanism of making payments through LiqPay, WISE and PAYONEER payment services and the features of the functioning of these payment systems are described. The nuances of the acquiring payment transaction processing process, as well as the procedure for introducing an international bank account number (IBAN) in Ukraine, were traced and indicated. Facilitation of greater integration of the Ukrainian payment space with the European one due to savings on bank commissions and speed of operations was revealed. The dependence of the development of electronic commerce on the perfection, volume and convenience of payment systems is singled out.
Pathways for transformative change in biodiversity politics: Examining the significance of the Global Biodiversity Framework’s ‘Considerations’
Authors: Hutchinson Alison , Zito Anthony , McGowan Philip
Published: October 2024

This paper examines the ‘Considerations’ that are intended to underpin the implementation of the Kunming-Montreal Global Biodiversity Framework (KMGBF). With so little time to meet the 2030 mission of transforming conservation approaches and curbing biodiversity decline, we reflect on the opportunities the Considerations present for transformative governance in biodiversity conservation. We discuss how contrasting worldviews and foundations of knowledge shape the Considerations, and inform the Framework more broadly, and highlight where areas of ambiguity between anthropocentric and nature-centred approaches arise. We contend that if the global community is to meaningfully change the trajectory of species extinctions and biodiversity loss, transformative changes are needed in the values held and expressed towards nature in political, economic, and social spheres. We conclude by suggesting implementation tools and processes to help foster the meaningful integration of the more boundary-pushing Considerations in wider biodiversity governance and practice.
The best of both worlds: why antipredator traits are lost in predator free havens and how to keep them
Authors: LeBas Natasha , Rodger Jennifer , Lymberry Rowan , Tomkins Joseph , Blache Dominque
Published: October 2024

As a response to the current biodiversity crisis, active management of threatened species has become more frequent (Hoffmann et al., 2010), with predator free havens an increasingly common conservation management strategy (Legge et al., 2022). In Australia, where introduced predators such as cats (Moseby et al., 2015) and foxes (Radford et al., 2018) are one of the largest threats to native fauna, havens have played a key role in maintaining viable populations of endemic mammals (Legge et al., 2018). Concerns, however, have been increasingly raised that populations in predator free havens, or similarly those that are captive bred or on islands, rapidly lose antipredator traits (Beauchamp, 2004; Blumstein & Daniel, 2005; Harrison, Phillips, et al., 2023; Jolly & Phillips, 2021; Jolly et al., 2018; Smith & Blumstein, 2008). Here we suggest that some of the selective pressures and mechanisms that may explain the rapid loss of these traits may have been overlooked. There is convincing evidence within the animal production literature that a fearful, high anxiety temperament (typically associated with anti-predator behaviours) is genetically linked to reduced fecundity; a relationship that may explain the rapid loss of fearful antipredator traits as a byproduct of selection for increased fecundity. We also propose a mechanism by which antipredator behaviour could be maintained in populations that are expected to evolve predator naivety.

Primary data includes tool cycle time and work efficiency, actual fuel consumption as well as road geometry and distance to disposal. Secondary data in the form of regional performance maps, equipment specifications, rainfall data, equipment working hours data, drone maps for August 2023 and contours. Based on the results of research in the field, factors that influence fuel consumption such as road geometry, road conditions and distance to overburden disposal are still not in accordance with established standards. The productivity of the DX800LC Excavator is 279.59 BCM/hour, the Doosan DA45 ADT is 60.47 BCM/hour and the Volvo A40G ADT is 59.37 BCM/hour. For Doosan DX800LC Excavator fuel consumption is 48.21 liters/hour, ADT Doosan DA45 is 26.62 and ADT Volvo A40G is 23.72 liters/hour. The actual fuel comparison for the two haulers is that the ADT Volvo A40G is more efficient than the ADT Doosan DA45 both in terms of fuel consumption and fuel costs.

Post-mining due to mining activities will produce heavy metals in the form of acidic water and accumulate in the land. The poor quality of the land used by tin mining causes damage to the land ecosystem so that the land cannot be regrown by vegetation and the Pb (Lead) content in tin tailings is 6.29 ppm. The aim of this research is land restoration, namely carrying out revegetation using sunflower plants to absorb the heavy metal Pb with the concept of edutourism. The method used is a simulation of planting sunflowers on an ex-mining area of 1 Ha, with a planting distance of 1 m, the number of sunflower plants is 8540. The research results show that with the sunflower garden concept by planting 8540 sunflowers, the Pb level that can be absorbed by the plants is 2.8310 kg.

East Aceh District is one of the areas that has a high stunting prevalence rate/above the Aceh Provincial average of 33,5 percent. This means that, according to WHO, East Aceh District has a poor public health problem or a chronic stunting problem. The purpose of this study was to identify the socio-economic determinants of stunting and formulate an alternative model for handling stunting in East Aceh District. This research used a qualitative approach, whit primary data sources through FDGs and interviews with relevant agencies. After obtaining result about the determinants of stunting, an analysis was carried out using the SWOT method to obtain an alternative model. The results of the study obtained that the dominant factor causing stunting is the family economy and the alternative handling model is through empowering village communities in meeting food needs independently.
A Space Propulsion System without Mass Ejection
Authors:   Independent researcher, Associate Fellow, AIAA. Israel, Lorber Azriel
Published: October 2024

Flight performance of long-range spacecraft is limited by the need to lift large amounts of fuel into orbit; thus, a propulsion system which will not depend on mass- ejection will be a most welcome development. Various past proposals which attempted to achieve this were rejected because it was thought that they contradicted basic laws of physics. An experimental mechanical device which operates without mass-ejection, (or interaction with the environment), and which can serve as a spacecraft propulsion system, was constructed and successfully tested. It is based on manipulating centrifugal forces, internally generated by rotating masses, and is not size or scale dependent. Full explanation, with photos and movies of its construction and operation, is presented. When fully developed, this technology will enable constant long-duration acceleration of spacecraft (decreasing flight times), permit novel physics research, or enable hovering with or without the presence of atmosphere.
Designing Metallic Neutral Density Filters with Constant Optical Density Versus Wavelength
Authors:   Willey Optical, Melbourne, FL 32901, USA, Willey Ronald R.
Published: October 2024

Observations in space and on earth can be subject to wide dynamic ranges of light levels which may need to be controlled by neutral density filters. The optical density (OD) of neutral density (ND) filters made with single metal layers is often not very neutral or constant in OD versus wavelength over the wavelength band of interest. Photographers are the major users of quantities of ND filters, but there are many other applications for smaller numbers of ND filters. There are a limited number of publications on how to design metallic ND filters. It is shown here that designs of metal-dielectric-metal (MDM) can be designed to have more constant OD over a wavelength band. Designs are shown employing software which accommodates the fact that the indices of thin metal films usually vary with film thickness
