Исследован процесс мицеллообразования октильсульфата натрия (C8H17SO4Na+ ) в водных растворах в зависимости от концентрации поверхностно-активного вещества (ПАВ), превышающего критическую концентрации мицеллообразования (ККМ). Сдвиг частот нормальных колебаний (1063 и 1305 см-1 ) и их относительные интенсивности, которые характеризуют необычные изомерные формы, использованы в качестве индикатора образования мицелл. Количественные данные параметров спектра КР света использованы для определения солюбилизации органических добавок к мицеллярным растворам. Изменение полуширины симметричного нормального колебания O-SO3 свидетельствует о сильном взаимодействии с Са+ , может быть даже с образованием комплекса. По видимому этот кооперативный эффект приводит к уменьшению каталитической способности мицелл в присутствии Са+ .

Are preoperative monocytes and HDL values ​​an early predictor of recurrence in the surgical ablation treatment of atrial fibrillation?
Authors: SAMSA Muhittin Zafer , TOR OCAK Funda
Published: March 2023

Objective: Monocyte HDL (high-density lipoprotein) cholesterol ratio has been accepted as a newly emerging cardiovascular prognostic marker. The aim of this study is to investigate the determinants of monocyte and HDL cholesterol values ​​in the early recurrence of atrial fibrillation (AF) treated with cryoablation and radiofrequency ablation. Materials and Methods: This retrospective study was conducted between September 2006 and July 2014 in the Department of Cardiovascular Surgery, Adana City Hospital, Health Sciences University, including 100 patients who underwent surgical AF ablation with open heart surgery. Logistic regression analysis was used to determine monocytes and HDL cholesterol values, which are among the factors affecting recurrence in the first 3 months postoperatively. Results: 100 patients who underwent surgical ablation together with open heart surgery were evaluated for early postoperative recurrence. According to the logistic regression analysis, the most effective features and measurements for early recurrence were diabetes mellitus (DM), AF duration, left atrial diameter, and low HDL cholesterol and high monocyte values ​​before the procedure. Conclusion: Preoperative low HDL and high monocyte values ​​can be considered as a determining factor for early recurrence in surgical ablation treatment of AF.

Improving the System of Legal and Civic Education of Students in Higher Education Institutions
Authors: Dianov Sergei Aleksandrovich , Dianova Yuliya Viktorovna
Published: March 2023

The subject of the authors' research is the problem of improving the mechanisms of legal education and civic education of students in educational institutions of higher education. Attention is drawn to the presence of scenarios of legal education (personal adaptation programs) of students in advanced Russian universities. At the same time, the formal nature of such programs is recognized, their abstraction from the existing realities in the educational environment of the university. It is emphasized that in the professional pedagogical community back in the 2000s, by no means difficult questions were postulated about what performance indicators of legal education and civic education in higher education should consist of. An equally important topic for discussion is the complexity of organizational and regulatory nature in determining the criteria for the effectiveness of legal education methods, which are proposed to be used in training sessions. The authors of the article formulated project proposals intended for practical application in the implementation of strategies of legal education and civic education of students at universities, taking into account the profile of the main professional educational programs being implemented. The author's programs on regulatory and legal support of education (professional, profile) for students of pedagogical, law enforcement and technical (engineering) universities are described.
Changes in soil carbon, nitrogen, and phosphorus in Pinus massoniana forest along altitudinal gradients of subtropical karst mountains
Authors: Nie Kun , Xu Ming , Zhang Jian
Published: March 2023

Changes in altitude have a long-term and profound impact on mountain forest ecosystems. However, there have been few reports on changes in soil carbon, nitrogen, and phosphorus contents (SCNPC) along altitudinal gradients in subtropical karst mountain forests, as well as on the factors influencing such changes. We selected five Pinus massoniana forests with an altitudinal gradient in the karst mountain area of Southwest China as research objects and analyzed the changes in SCNPC along the altitudinal gradient, as well as the influencing factors behind these changes. Soil organic carbon, total nitrogen, and available nitrogen contents first increased and then decreased with increasing altitude, whereas the contents of total phosphorus and available phosphorus showed no obvious trend. In the karst mountain P. massoniana forest, SCNPC in the topsoil is most significantly affected by total glomalin-related soil protein (TG) and soil moisture content (SMC) (cumulative explanatory rate was 45.28–77.33%), indicating that TG and SMC are important factors that affect SCNPC in the karst mountain P. massoniana forest. In addition, the main environmental factors that affect SCNPC in the subsoil showed significant differences. These results may provide a better scientific reference for the sustainable management of the subtropical mountain P. massoniana forest.
Integrated reporting in the public sector – special focus on portuguese public university
Authors: Marques Maria da Conceição da Costa
Published: March 2023

Sustainability reporting began to emerge in the 1990s, with the aim of providing stakeholders with information on the company's performance through social, governance and environmental aspects (Eccles and Spiesshofer, 2017). The relevance of non-financial information has grown significantly, as more and more investors argue that financial information is not enough to understand the performance and value of the organization. At a time when companies want greater transparency, it is necessary that social justice and environmental protection are increasingly a reality. Information users, on the other hand, are more aware of the need to promote sustainable long-term profitability. Focusing on universities, these are essential pillars of society. Its main mission includes two main aspects, which are teaching and research; however, these entities were also called upon to contribute to society through the provision of services, their third mission. Do all public universities in Portugal produce sustainability reports? Or will it just be a few? The aim of this study is to carry out a survey of the accounts of these institutions, to assess whether they include sustainability reports, through which they convey to stakeholders their practices in this area.

The proposed system of monitoring and evaluation of service quality is aimed at customer evaluation and integrated consideration of communal, housing, organizational, informational components and allows you to determine the effectiveness of the managing organizations. The organizational structure, based on the creation of two main units – back and front offices, which allows to implement a customer-oriented strategy, is also considered. Within the limits of the new organizational structure the system of revealing of need and opinions of owners of rooms in apartment houses by means of absentee voting with application of new information technologies is offered. Thus, the given system of monitoring and estimation of quality of housing and communal services will allow to realize feedback between consumers and the managing organizations, and to increase customer satisfaction of quality of services.
Fertility Evaluation of Adult Female Wistar Rats Administered with Ethanolic Extract of Pausinystalia yohimbe Stem Bark
Authors: Okwakpam Felicia N. , Otobo Miebaka B. , Igwe Felix U. , Iyo A.
Published: March 2023

Pausinystalia yohimbe (P. yohimbe) stem bark powder is commonly used as seasoning for barbecue beef in Nigeria and some West African countries. This study evaluated the effect of ingesting ethanol extract of P. yohimbe stem bark on some hormones and tissues linked with fertility in female Wistar rats. A total of fifteen adult female Wistar rats weighing between 140 - 160g were used for this study after an initial Acute Toxicity test was done to establish a safe dose range of the extract. The animals were randomly divided into three groups of five rats per group. Group 1 served as control and received normal saline while Groups 2 and 3 received 400 mg/kg and 800 mg/kg body weight (bw) of ethanol extract of P. yohimbe stem bark respectively, via oral gavage, for 21 days. At the end of the treatment period, the rats were weighed, sacrificed and blood, ovary and uterus samples collected for determination of reproductive hormones (follicle-stimulating hormone, estrogen, and progesterone) and histological examination using standard methods. The results showed that LD50 of the ethanol extract for the female Wistar rats was 3807.89 mg/kg bw. There were significant (p˂0.05) increases in body weight, estrogen and follicle-stimulating hormone (FSH) of the treated groups compared with the control. Histological examination also showed degenerative changes in the uterus of the rats in groups 2 and 3, with no alterations in the ovary when compared to control. These results suggest that continuous consumption of ethanol extract of P. yohimbe stem bark may alter the systemic concentration of estrogen and follicle-stimulating hormone as well as morphology of the uterus which may lead to reduced reproductive function and female infertility.
Research on the Mathematics Space Concept of Junior High School Students in China
Authors: Li Xiaoshuo , Yang Zezhong
Published: March 2023

The space concept is one of the main manifestations of the mathematics core competencies in the compulsory education stage as required by the Mathematics Curriculum Standards for Compulsory Education (2022 edition). In the past two decades, many scholars have studied the space concept, but there is no literature to systematically summarize the research results. Therefore, this paper adopts the literature analysis method to review 47 papers related to the mathematics space concept of junior high school students in China, and obtains the following conclusions: After the promulgation of the Mathematics Curriculum Standards for Compulsory Education (2022 edition), the research on the space concept has increased, but it is mostly theoretical research and less empirical research. The research is divided into six aspects: the connotation and components of the space concept, the division of the space concept's dimensions, the current development status of the space concept of junior high school students, factors influencing the space concept, ways to cultivate the space concept, and curriculum resources development. Studies on the dimensional division, the current development status, and the ways of cultivating the space concept are abundant. The division of dimensions and levels of the space concept provides a research approach to further understanding the development status of junior high school students. The research on the development status suggests that teachers should analyze the weak points in the space concept combined with the specific situation of students. The research on the cultivation ways innovates the design of teachers' teaching activities. But these studies all focus on the period before the promulgation of the new edition standards. There is a lack of research on the connotation and components, the influencing factors, and the development of curriculum resources. Therefore, it is necessary to analyze the research week's points further. The space concept can be interpreted from different perspectives in conjunction with other related disciplinary theories, the influence factors such as students' pre-preparation and teachers' teaching styles can be examined, and a variety of in-school and out-of-school resources and networked resources can be flexibly applied for curriculum development.

Published: March 2023

Aims: To find out the Effect of different levels of microbial enriched biochar with fertilizer doses on soil properties and yield under Soybean (Glycine max) –Wheat (Triticum aestivum) cropping sequence.
Study Design: Randomized Block Design (RBD).
Place and Duration of Study: The study was carried out at BAIF-Central Research Station, Urulikanchan, Ta. Haveli, Dist. Pune Maharashtra, India, during July 2021 to April 2022.
Methodology: The charcoal powder is treated with the different bio fertilizers viz. Rhizobium, Phosphate Solubilizing Bacteria (PSB), and Trichoderma. The farmyard manure at the rate of 10 tons per ha was mixed equally in all the treatments.The reduced recommended dose of chemical fertilizers in Soybean and wheat was 50% and 75%, where the microbial enriched biochar was applied to the soil at the rate of 5, 7.5, 10, and 15 tha-1 (Table-1). In the Kharif, the var. JS 335 (Soybean) and in the Rabi season, Wheat (var. Ankur Kedar) was sown in the same field. The charcoal was prepared and this wet microbial-enriched Biochar was used as per the treatment combinations in both the crops (Table 1).
Results: In Soybean crop all the growth parameters recorded highest readings and also a higher grain yield (25.89 qha-1) and straw yield (27.49 qha-1) and in Wheat all the growth parameters recorded highest readings and also higher grain yield of (43.19 qha-1) and straw yield of (45.78  qha-1) was recorded (Table 2 & 4) in treatment T3 (Biochar @ 7.5 t ha-1 + 75 % GRDF) and it is at par with GRDF.
Conclusion: It is concluded that in (T3) the application of microbial-enriched Biochar @ 7.5 t ha-1 + 75 % GRDF has given significantly higher grain yield (Soybean: 25.89 qha-1 and Wheat: 43.19 qha-1) and straw yield (Soybean: 27.49 qha-1 and wheat: 45.78 qha-1) over the GRDF in both Soybean and Wheat cropping sequence.
An Alternative Estimator for the Estimation of Polynomial Regression Model (PRM)
Authors: Oladapo David I. , Ametepey Eli Yaovi , Akinsola Victor O. , Amao Folake A. , Atoyebi Samuel B.
Published: March 2023

The maximum likelihood (ML) approach is used to fit the polynomial regression model (PRM) in the presence of small sample sizes. The ML technique is applied to the data of PPP, GDP, and output/total production cost in Nigeria between 1989 and 1999. The results of the analyses (by ML approach and that of the OLS) are presented for comparison. The analysis shows that the ML gives parameter estimates of 128.889, -5.24, -29.208, 10.523 and the OLS resulted in 128.009, 5.196, -30.376, 11.009. The analysis of the first data set (of iron content and weight loss of some specimen tested in a corrosion wheel set-up) shows that both estimators accounted for good fit because they both have high R2 values and significant t-ratios. The result of the model fit of the four data sets using ML results in reasonable parameter estimates (with lesser S.E relative to the parameter estimates), lower MSE, and very high R2-values. Although both methods were generally well adapted, ML was more effective than OLS because it led to a smaller sample size's MSE.
