Abstract
In view of an impending termination of Russian gas supplies, it is necessary to take a closer look at the existing regulations in the event of a shortage in German gas supply. In this context, the legal framework provides that in the event of an acute shortage, the gas supply of individual consumers will be restricted or even stopped by the competent authority, thereby rendering the effect of the market for the distribution of scarce goods ineffective. This situation must be prevented. In principle, priority is given to private households and social services, so that primarily the industry would have to reduce their consumption of gas. However, given the threat of widespread disruption to German industrial production, saving potentials should be leveraged in all sectors. This is because an extensive supply disruption to German industrial operations would result in extensive and incalculable societal costs due to cascading effects. It is therefore also in the best interests of the population to avert such an undersupply through joint efforts. First of all, the usage of natural gas in power generation should be reduced significantly to enable or increase the filling of storage facilities. Additionally, current studies also point to possible reduction potential in the household sector, for example through moderate adjustments of room temperature. Such measures can help to get through the next winter without endangering Germany too much as an industrial and business location.

Abstract
The local release detection technology of traditional Internet of Things (IoT) sensing terminal equipment cannot realize the integration of the cloud and IoT edge, resulting in obvious local release detection errors and low technical sensitivity. To this end, a local release detection technology comprising ultra-high frequency (UHF) IoT sensor terminal equipment based on cloud edge collaboration is proposed. The transient earth voltage signal coupling module of the perception layer is used to collect data locally published by the device. This paper uses edge computing to reduce information redundancy. The cloud computing application layer adopts the time difference positioning method to realize the partial discharge detection of the UHF IoT sensor terminal equipment. When an abnormality occurs in the terminal equipment, an alarm is triggered. The experimental results show that the average accuracy of this method in detecting partial discharge is as high as 93.89 %. The detection time of this method is short and its detection time of partial discharge phenomenon is as low as 4 ms. The fitting effect of the proposed method is better in detecting amplitude and discharge and the two have a linear relationship. This method also has higher detection sensitivity, can detect the partial discharge of different types of terminal equipment, and its application effect is good.

BACKGROUND AND OBJECTIVES
Options to treat and prevent episodic wheezing in children are scarce. Our objective was to assess the efficacy of intermittent tiotropium bromide treatment in early childhood episodic wheezing.

METHODS
This 48-week, randomized, open-label, controlled, parallel-group trial was conducted at 4 hospitals in Finland. Children aged 6 to 35 months with 2 to 4 physician-confirmed episodes of wheeze and/or shortness of breath were considered eligible. Study participants were randomly allocated to receive 1 of 3 treatments: once-daily tiotropium bromide 5 µg for 7 to 14 days during respiratory tract infections and as-needed albuterol sulfate 0.2 mg (n = 27), twice-daily fluticasone propionate 125 µg for 7 to 14 days during respiratory tract infections and as-needed albuterol sulfate 0.2 mg (n = 25), or as-needed albuterol sulfate 0.2 mg alone (n = 28). The primary outcome was efficacy, assessed as intention-to-treat by comparing the proportion of episode-free days (the days lacking symptoms or treatments) between the treatment groups.

RESULTS
The proportion of episode-free days was higher in those receiving intermittent tiotropium bromide (median 97% [interquartile range, 93% to 99%]) than in those receiving intermittent fluticasone propionate (87% [78% to 93%], P = .002), or with as-needed albuterol sulfate alone (88% [79% to 95%], P = .003). Adjustment with allergic sensitization, the baseline number of physician-confirmed episodes of wheeze and/or shortness of breath, or short-course glucocorticoid treatment in the 2 weeks before the enrollment, did not affect the result. Intervention-related adverse events were not seen.

CONCLUSIONS
Intermittent tiotropium bromide treatment may be an effective alternative to current therapies for episodic wheezing. Before implementation of use, further research on safety and efficacy is indicated.

Introduction: Down syndrome (DS) is a common genetic disorder, occurring in approximately 1 in 700 births. It results from an extra copy (triplication) of the whole or part of the long arm of chromosome 21 caused by different cytogenetic alterations: free trisomy, Robertsonian translocations, mosaicism, duplication of the critical region and other structural rearrangements. Non-Robertsonian chromosome translocations are very rare events with few cases reported. Case Report: We identified the non-Robertsonian translocation t(11;21)(p13;q22) and two chromosomes 21 in a female child referred with a clinical diagnosis of trisomy 21. The infant developed the transient myeloproliferative disorder at 17 months. Cytogenetic analysis was performed in lymphocytes and bone marrow metaphases according to standard procedure - G banding and fluorescence in situ hybridization. The karyotype study of the parents revealed that her phenotypically normal mother carries the same reciprocal translocation. Conclusion: This is the second report of the translocation t(11;21)(p13;q22), the first one resulting in DS. This description expands knowledge about cytogenetic variability in the etiology of DS. Future studies are needed to investigate the long-term clinical effects of the trisomy 21 associated with t(11;21)(p13;q22).

Nasopharyngeal carcinoma is the most frequent head and neck cancer. The incidence of nasopharyngeal carcinoma significantly increased. Nasopharyngeal carcinoma is associated with risk factors linked to a lifestyle that usually begins in adolescence and young adulthood, such as undergraduate students. This research identifies undergraduate students' knowledge, attitude, and behavior about nasopharyngeal carcinoma. The study used a descriptive study with a cluster sampling method. As many as 100 undergraduate students from 8 faculties in Tanjungpura University filled out a questionnaire and analyzed using a statistical program with a descriptive statistical test. As much as 82% of respondents had received information about nasopharyngeal carcinoma from various sources. Knowledge was divided into 3 categories of levels, namely good (76-100% correct), fair (56-75% correct), and poor (56%). At the same time, attitude and behavior were divided into positive (score20) and negative (score20). The test results showed that the level of knowledge of the undergraduate students of 52% was good, the attitude was 100% positive, and the behavior was 100% positive. Therefore, undergraduate students at Tanjungpura University had good knowledge, a positive attitude, and positive behavior toward nasopharyngeal carcinoma. This study implies that adequate information is important in determining knowledge, attitudes, and behavior towards nasopharyngeal carcinoma.

Academic buoyancy of university students and its relationship to academic average in light of some demographic variables
Authors: Abdellatif Mohamed Sayed 
Published: August 2022

Academic buoyancy reflects the student's ability to encounter the ordinary challenges he faces in the academic context, and it positively contributes to the student's behaviors. This study aims to measure the level of academic buoyancy among university students, identify its relationship to their academic average, and determine the differences in their academic buoyancy level in terms of gender and academic discipline variables. The descriptive-analytical research design was utilized. The academic buoyancy scale was applied to (243) university students (male-female). Data were statistically analyzed using correlation coefficient, arithmetic mean, and two-way ANOVA. Results demonstrated that students have a high level of academic buoyancy, there was a significant correlative relationship between academic buoyancy and academic average, and there were no significant differences in the academic buoyancy level due to gender (male-female), academic discipline (theoretical-practical). The research recommended increasing students' academic buoyancy level to help them encounter academic pressures and challenges and to solve the problems they face in their academic lives effectively.

Students’ perceptions on the difficulty of biochemistry concepts covered in Rwandan secondary school biology curriculum
Authors: Munyemana Jean Jacques , Nsanganwimana Florien , Gaparayi Gaspard 
Published: August 2022

This study explored the Rwandan secondary students’ opinions on learning biochemistry concepts covered in the Rwandan advanced level of secondary school biology curriculum, and the reasons behind the difficulty of the concepts. In this research, sequential exploratory mixed-method designs were adopted. The sample comprised 195 secondary school students, who were purposively selected from the schools in Rwamagana and Kayonza districts of Rwandan Eastern Province. Data were collected using self-administered questionnaires and focus group semi-structured interview guides. Data analysis was carried out using both quantitative and qualitative approaches. Results from this research showed that photosynthesis and respiration are the major units that are challenging to study with the respective percentages of 62.5 and 75.1. On the other hand, the concept of enzymes is the most difficult according to students’ views. The lack of adequate laboratory and learning resources and teachers’ teaching styles were reportedly the reasons behind the difficulty of these units. Therefore, the provision of continuous professional development training on advances in teaching and learning biochemistry to in-service teachers would be one of the strategies to enhance students’ understanding of these concepts.

Keywords: Biochemistry, photosynthesis, enzymes, respiration, secondary school students.

The purpose of this research is to determine the creative thinking and learning technology competencies of biology teacher candidates and to get their opinions on the methods of creating these competencies. The mixed method, in which quantitative and qualitative methods are used together, was preferred as a research model. The study group of the quantitative part of the research consists of 482 biology teacher candidates studying at various universities in Kazakhstan in the 2021–2022 academic year, and the study group of the qualitative part consists of 25 biology teacher candidates. Two different measurement tools were used in the study. In collecting the quantitative data of the research, the scale of creative thinking and learning technology competencies, and a semi-structured interview form in collecting the qualitative data were prepared by the researchers. As a result of the research, the creative thinking and learning technology competencies of the biology teacher candidates participating in the research were found to be moderate. The creative thinking and learning technology competencies of the biology teacher candidates participating in the research did not show a significant difference according to the gender and the class they are studying in. Considering the qualitative findings of the research, the majority of biology teacher candidates mentioned the importance of giving importance to personal development and participating in creative thinking activities such as courses, seminars and conferences in order to develop creative thinking. Biology teacher candidates stated that in order to use learning technologies effectively in education, it is necessary to be interested in technology and to use technology in education. The vast majority of biology teacher candidates, on the methods of constructing creative thinking and learning technology competencies, suggested creating course content and organising creative thinking and technology seminars in universities.

One of the most dangerous effects of radiation on health is reproductive dysfunction, often leading to infertility. Available studies on the effects of radiation on spermatogenesis and fertility have not considered the possibility of using restorative therapy. One of the modern methods of infertility treatment is the introduction of autologous blood plasma with an increased content of platelets and native growth factors. Currently, there are no studies on the study of offspring obtained by using this method of infertility treatment and the assessment of its teratogenicity. Purpose of the study: morphological analysis of offspring of male rats irradiated with electrons at a dose of 2 Gy and receiving platelet-rich plasma. Male Wistar rats (n=35) were once subjected to targeted ionizing radiation at a NOVAC-11 pulsed electron accelerator at a dose of 2 Gy. To half (n=15) of the irradiated animals were injected with platelet-rich plasma and insulin-like growth factor-1 for 12 weeks, after which the males of both groups were placed with intact females (n=30) to produce offspring. The state of the developing offspring was assessed by morphological analysis after the removal of pregnant females from the experiment on the 20th day of prenatal development. Pregnancy was observed only in females bred by control males and males treated with platelet-rich plasma. Classical histological methods and X-ray computed microtomography were used. As a result of the study, it was found that the weight and size of the offspring from the control and experimental groups did not have macroscopic differences; light microscopy did not reveal significant changes in their histological structure. Pathological changes in the development of the offspring of males of the experimental group who received platelet-rich plasma after electron irradiation with a dose of 2 Gy using computed microtomography were also not detected. The obtained data indicate about of effectiveness of the treatment of the infertility of irradiated male rats with platelet-rich plasma, as well as the absence of its teratogenic effects.

Objective: To assess the factors associated with anemia in renal transplant recipients with functioning grafts in Sana’a city, Yemen.
Methods: One hundred and thirteen adult renal transplant recipients with functioning grafts were enrolled in this study in the period from Janury to December 2014. Biodata and clinical data were collected using a pre-designeddata collection sheet. Hemoglobin (Hb) concentration was measured, and anemia was defined as Hb concentration less than13.0 g/dLin males and less than 12.0 g/dL in females. The factors associated with anemia were analyzed, and independent predictors of post-transplant anemia (PTA) among renal transplant recipients were identified using a multivariable logistic regression model.
Results: PTA was detected in 23.0% of renal transplant recipients with functioning grafts. Bivariate analysis showed a significant association of PTA with age of 50 years or older (Odds ratio (OR) = 2.7; 95% CI: 1.10–6.72; P = 0.03), history of acute rejection (OR = 3.6; 95% CI: 1.17–11.28; P = 0.019) and delayed graft function (OR = 6.2; 95% CI:1.60–24.16; P = 0.004). Multivariable analysis using a logistic regression model identified history of acute rejection (adjusted OR = 3.9; 95% CI: 1.11–12.94; P = 0.034) and delayed graft function (adjusted OR = 4.6; 95% CI: 1.07–19.81; P = 0.04) as independent risk factors for PTA among recipients. However, no association was found between PTA and recipient’s gender, graft source, immunosuppressive protocols, erythropoietin treatment or use of antihypertensive drugs.
Conclusions: The prevalence of PTA among Yemeni renal transplant recipients is high, with history of acute rejection and delayed graft function being the independent risk factors. Therefore, it is recommended that physicians involved in renal transplantation consider the investigation and follow-up of transplant recipients for PTA and adopt appropriate preventive and therapeutic measures.

Published: August 2022

Objective: To determine the prevalence and risk factors for Trichomonas vaginalis infection among pregnant women seeking health care in Sana’a city.
Methods: This cross-sectional study was conducted among pregnant women seeking health care in private clinics and governmental primary health care centers in Sana’a during the period from October 2014 to June 2015. Data on sociodemographic and clinical characteristics as well as possible risk factors of T. vaginalis infection were collected from 287 pregnant women using a pre-designed questionnaire by trained researchers. Vaginal discharges were then collected and examined microscopically for motile T. vaginalis trophozoites.
Results: The overall prevalence of T. vaginalis infection was 11.1%, with a higher infection rate among pregnant women aged 26-40 years old, housewives and rural residents. Age, literacy status and the age at first sexual intercourse were signiﬁcantly associated with T. vaginalis infection among pregnant women. Presence of vaginal discharge (OR = 8.33; 95% CI: 2.47–28.03, P <0.001), itching (OR = 2.57; 95% CI: 1.02–6.48, P = 0.027) and presence of unpleasant odor (OR = 4.37; 95% CI: 1.63–11.70, P = 0.001) were the clinical manifestations significantly associated with T. vaginalis among pregnant women.
Conclusions: T. vaginalis is prevalent among pregnant women seeking health care in Sana’a, particularly housewives, illiterate women and those coming from rural areas. Presence of vaginal discharge with unpleasant odor and itching are associated with a higher risk of infection among symptomatic women. Further large-scale studies are required to determine the prevalence and risk factors among women of the reproductive age in Yemen.

Objective: To assess hepatic and renal functions among petrol stations workers in Sana’a city, Yemen.
Methods: A case-control study was carried out in Sana’a city, in the period from November 2017 to April 2018. Cases included 109 eligible petrol station workers exposed to petrol for at least six hours daily over a period of six months or more, while 109 apparently healthy office workers were recruited from the University of Science and Technology as controls. Data were collected using a pre-designed questionnaire through face-to-face interview. Then, blood samples were collected from cases and controls and tested for albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), urea and creatinine in the Laboratory Department of the University of Science and Technology Hospital. Data were analyzed using SPSS, version 23.0.
Results: The mean concentration of serum albumin among petrol station workers was significantly lower than the controls. In contrast, the mean level of serum ALP was significantly higher among the petrol station workers than the controls. On the other hand, there were no statistically significant differences in the mean levels of serum ALT and AST between the two groups. Although the mean concentrations of creatinine and urea were higher among the controls than the petrol station workers, the difference was only significantly higher for creatinine among office workers.
Conclusions: Although no specific biochemical abnormalities exist in the hepatic and renal functions of petrol station workers in Sana’a city, these parameters may show evident effects with prolonged exposure to petrol components. Further longitudinal studies with larger sample sizes, longer durations of exposure and regular follow-up are recommended to assess the impact of long-term exposure to petrol on hepatic and renal functions.
