Authors: Amaral Karoline Fernanda Silva , Oliveira Andréa dos Santos , Almeida Tanismare Tatiana 
Published: July 2021

Objetivou-se nesta pesquisa avaliar o potencial alelopático dos extratos de folhas de fedegoso e picão preto na germinação e desenvolvimento de plântulas de gergelim. Para obtenção do extrato, as folhas colhidas foram secas em estufa por 24 horas a 50 ºC, trituradas e adicionado água na proporção de 1g/ 10 mL. Essa mistura foi mantida em frasco pelo período de 24 horas e diluída nas concentrações de 10, 30, 50 e 70%. O delineamento experimental foi inteiramente casualizado, no esquema fatorial de 2 x 5 (espécies x concentrações 0, 10, 30, 50 e 70%) e quatro repetições. Após a montagem do teste de germinação as sementes foram mantidas em BOD com fotoperíodo de 12 horas e temperatura de 25 ºC. Juntamente com a germinação foram realizadas contagens diárias para cálculo do índice de velocidade de germinação e ao final foram medidos o comprimento de hipocótilo e radícula (cm) das plântulas normais, evidenciando que o extrato de picão preto inibe a germinação e vigor de sementes de gergelim em concentrações superiores a 30%. No caso do fedegoso pode-se inferir que o efeito alelopático é maior que o picão, uma vez que, afeta a germinação a partir da concentração de 10 %.

Authors: Voloshin O.R. , Kopko I.E. 
Published: July 2021

The article discusses the problem of behavior and improving the health of students. According to the results of many studies, in recent years there has been a tendency among students to reduce their level of health and physical activity. There are many methods for assessing health, such as the method of determining biological age.
The aim of the study is to compare student passports and their biological age. The study was conducted on the basis of the Faculty of Biology and Natural Sciences of DSPU. Ivan Franko, which was attended by 43 students of I-IV courses. The following research methods were used to determine the biological age: testing; questionnaires, observations; methods of generalization, synthesis and analysis. It was found that in comparison with senior courses, students of I-II courses have a biological age higher than the passport. As a result of obtaining information that in the vast majority of respondents who ignored a healthy lifestyle and low low level of physical activity, the actual biological age exceeded the value of the required biological age, they were characterized by accelerated aging and poor health.
Analysis of the results of the study showed that most students I-IV showed poor static coordination, decreased attention and reaction speed, as well as reduced respiratory arrest during exhalation. Based on the results of the study, a manual was developed for students with recommendations for reducing biological age.

This article is devoted to the implementation of an experimental program and, thus, changes in the training process of athletes to optimize their physical condition.
The ultimate goal of the study by Karpushyn Mykhailo and Oleksiy "Dynamics of indicators of physical condition of athletes under the influence of training programs" is to improve the results of athletes, optimize their physical shape with the help of updated training programs and training units. The tasks are as follows: 1. To analyze the existing situation and on this basis to form updated training units; 2. Get acquainted with the existing literature and coverage of this topic; 3. To develop an updated method of training for the studied group of athletes; 4. To study the influence of the updated program of specific training programs and blocks on the physical status of athletes. The conducted experimental study showed a positive dynamic progress in the physical fitness of the participants of the experimental group. Thus, it becomes obvious the possibility of achieving better physical condition in a shorter period of time, the qualitative development of physical shape, with the correct distribution of loads.
The conclusions after the study are obvious - a well-formed training technique in combination with an individual approach to each athlete gives a qualitatively new result: the optimal physical shape of the athlete in a short time and less traumatic. Thus, in the training process, quality is important, not quantity, which ultimately guarantees the dynamics of growth.

Authors: Nduka Ijeoma 
Published: July 2021

Background: Postnatal period is as important as pregnancy and childbirth. Half of all postnatal deaths occur during the first week after birth. During postnatal period, the mother’s body undergoes major changes from pregnancy. Therefore, there is need for continuity of care after birth to prevent and manage complications that may arise during postnatal. This study was carried out to determine factors associated with the utilisation of postnatal care services in a rural community in Abia state.
Methods: This was a descriptive cross-sectional study conducted from March 2019 to May 2019 among women living in Amuvi community in Arochukwu Local Government Area (LGA)of Abia state. The study participants were women of reproductive age group (15-49 years) who had at least been pregnant once, carried pregnancy to full maturity and delivered at term. Data was collected using pre-tested semi-structured interviewer-administered questionnaire.
Results: Four hundred and sixty-seven (467) women participated in the study. Four hundred and forty-three (95.1%) women attended postnatal visits while 23 (4.7%) did not. Reasons given for attending postnatal care by respondents were; routine check-ups, counselling on family planning, appointment with health workers 54 (11.7%), same day appointment as child’s immunisation, child was sick. Respondents who were married were 2 times (AOR=2.587, 95% CI:-0.878-0.120) more likely to use postnatal care services than single mothers. Mothers who had an occupation were 2 times (AOR=2.897, 95% CI: 0.051-0.267) more likely to use postnatal care services than those who did not. Husband’s occupation was statistically significant with utilisation of postnatal services.
Conclusion: Utilisation of postpartum care services was high among women in Amuvi community of Abia state. PNC services utilisation were associated with marital status, mother’s occupation and husband’s educational status.

На сегодняшний день в местных птицеводческих хозяйствах сложилась практика, когда помет птицефабрик практически не перерабатывается, и это приводит к загрязнению близлежащих к территории фабрики почвы, воды и воздуха. Одна из таких птицефабрик размещается непосредственно в зоне города Актобе вблизи жилых массивов, следствием чего является ухудшение условий жизни жителей ближайших районов города. Зловоние является постоянным спутником этих мест. Давно назрела необходимость внедрения экологически и экономически рациональных технологий. Авторы доказывают, что наиболее целесообразным выходом из создавшейся ситуации может быть разработка и внедрение технологии производства эффективных удобрений на основе птичьего помета, решающее проблему тяжелого экологического состояния зон размещения птицефабрик, с одной стороны, и проблему катастрофического снижения плодородия используемых в сельском хозяйстве почв, с другой стороны. В результате анализа существующих методик переработки птичьего помета был рассмотрен и предложен метод интенсивного компостирования помета нагнетанием воздуха для производства органического и органоминерального удобрений. Метод включает отдельные стадии, реализующие процессы сушки, обеззараживания, аэробной ферментации и гранулирования обогащенного птичьего помета.

Authors: Salmanian Kefayat , Marashian Fatemeh Sadat 
Published: July 2021

Background: Understanding the disease symptoms is among the important psychological and behavioral variables in cancer treatment, which is based on the acquisition of information from different sources and patient's beliefs and can affect the mental health and capability of the individual in compliance with the disease. The present study aimed to investigate the relationship of coping strategies with death anxiety through the mediation of disease perception in patients with breast cancer in Abadan city in 2020.
Methods: The study was a descriptive correlation performed by path analysis. The statistical population included all patients with breast cancer in Abadan city and 200 of which were selected as the sample of the study using convenience sampling. The research instruments included the Death Anxiety Scale (DAS), the Ways of Coping Questionnaire (WCQ), and the Brief Illness Perception Questionnaire (Brief IPQ). The proposed model was evaluated using path analysis with AMOS software.
Results: The results showed that there was a significant association between problem-focused strategy and disease perception (P= 0.002), problem-focused strategy and death anxiety (P= 0.001), emotion-focused strategy and disease perception (P= 0.001), disease perception and death anxiety (P= 0.001). There was no significant association between problem-focused strategy and death anxiety. The results of path analysis indicated that disease perception played a mediating role in the association between the emotion- and problem-focused strategies with death anxiety (P= 0.01).
Conclusion: According to the results of the study, the proposed model had a good fit and is an important step in identifying the factors affecting the death anxiety of patients with breast cancer.
A realistic review of family-based interventions for children of substance abusing parents
Authors: Usher Amelia M. , McShane Kelly , Dwyer Candice 
Published: July 2021

<p>Background</p>
<p>Millions of children across North America and Europe live in families with alcohol or drug abusing parents. These children are at risk for a number of negative social, emotional and developmental outcomes, including an increased likelihood of developing a substance use disorder later in life. Family-based intervention programs for children with substance abusing parents can yield positive outcomes. This study is a realist review of evaluations of family-based interventions aimed at improving psychosocial outcomes for children of substance abusing parents (COSAPs). The primary objectives were to uncover patterns of contextual factors and mechanisms that generate program outcomes, and advance program theory in this field. </p>
<p>Methods </p>
<p>Realist review methodology was chosen as the most appropriate method of systematic review because it is a theory-driven approach that seeks to explore mechanisms underlying program effectiveness (or lack thereof). A systematic and comprehensive search of academic and grey literature uncovered 32 documents spanning 7 different intervention programs. Data was extracted from the included documents using abstraction templates designed to code for contexts, mechanisms and outcomes of each program. Two candidate program theories of family addiction were used to guide data analysis: the family disease model and the family prevention model. Data analysis was undertaken by a research team using an iterative process of comparison and checking with original documents to determine patterns within the data. </p>
<p>Results </p>
<p>Programs originating in both the family disease model and the family prevention model were uncovered, along with hybrid programs that successfully included components from each candidate program theory. Four demi-regularities were found to account for the effectiveness of programs included in this review: (1) opportunities for positive parent-child interactions, (2) supportive peer-to-peer relationships, (3) the power of knowledge, and (4) engaging hard to reach families using strategies that are responsive to socio-economic needs and matching services to client lived experience. </p>
<p>Conclusions </p>
<p>This review yielded new findings that had not otherwise been explored in COSAP program research and are discussed in order to help expand program theory. Implications for practice and evaluation are further discussed.</p>

Published: July 2021

<p>The role of the host immune response in determining the severity and duration of an influenza infection is still unclear. Inorder to identify severity factors and more accurately predict the course of an influenza infection within a human host, anunderstanding of the impact of host factors on the infection process is required. Despite the lack of sufficiently diverseexperimental data describing the time course of the various immune response components, published mathematical models were constructed from limited human or animal data using various strategies and simplifying assumptions. Toassess the validity of these models, we assemble previously published experimental data of the dynamics and role ofcytotoxic T lymphocytes, antibodies, and interferon and determined qualitative key features of their effect that should becaptured by mathematical models. We test these existing models by confronting them with experimental data and find thatno single model agrees completely with the variety of influenza viral kinetics responses observed experimentally whenvarious immune response components are suppressed. Our analysis highlights the strong and weak points of eachmathematical model and highlights areas where additional experimental data could elucidate specific mechanisms,constrain model design, and complete our understanding of the immune response to influenza. </p>

Published: July 2021

<p>This research aimed to investigate the feasibility of using direct amorphization of silicon induced by femtosecond laser irradiation for maskless lithography. A thin layer of amorphous silicon of predetermined pattern was first generated by irradiation by a femtosecond laser of Mega Hertz pulse frequency. The following KOH etching revealed that the amorphous silicon layer acted as an etch stop. Line width less than 1/67 the focused spot size was demonstrated and hence the proposed maskless lithography process has the potential of producing submicron and nanoscale features by employing a laser beam of shorter wavelength and a high NA focusing lens. Scanning Electron Microscope (SEM), a Micro-Raman and Energy Dispersive X-ray (EDX) spectroscopy analyses were used to evaluate the quality of amorphous layer and the etching process. </p>
