Genetic diversity within a population is reflected by variations in genetic material among individuals and can manifest at the phenotypic level through new characters or traits. The emergence of a large number of O. cumana races in a short period of time demonstrates that there are higher genetic variability in populations and a high ability to adapt in the face of environmental conditions. The aim of the research presented in this article was to study the intraand interpopulation genetic diversity and genetic relationships between individuals of three populations of O. cumana from different geographical regions of the People’s Republic of China based on molecular markers (ISSR and SSR). The high intrapopulation genetic variability calculated on the basis of the allelic diversity parameters and specific genetic diversity coefficients was revealed by SSR markers while as for the ISSR primers a high degree of genetic variations was found at the interpopulation level. UPGMA clustering and principal component analysis performed according to both sets of molecular markers allowed to devide all genotypes into 5 major groups for the degree of dissimilarity and level of aggression. This study is of interest in understanding the population genetic structure of the parasitic species of O. cumana from China and could contribute to the development of pathogen control durable strategies and effective sunflower breeding programs to broomrape resistance.

Identity convergence in the tapestry and painting of Ecaterina Ajder
Authors:   Institutul Patrimoniului Cultural, Republica Moldova, Spinu Constantin
Published: September 2021

Ecaterina Ajder, representative of the early `80s of plastic artists from the Republic of Moldova, constantly opts for endowing the work of art with innovative stylistic values. Plastic tradition and modernity originally connect in her creation, contributing to the generation of current messages through image. Preferring to materialize her thematic and plastic predilections in the genre of artistic tapestry and easel painting, Ecaterina Ajder has drawn and consolidated over the decades her unmistakable stylistic facet, in which the insurmountable landmarks of folk art have found a favorable artistic fulfillment and integration into relevant contemporary creative trends. In the artistic tapestry, the painter significantly capitalized both the aesthetic expressions obtained from the classic weaving, and from combining it with various techniques such as felt and embroidery. When referring to the easel painting she highlighted the traditional aspects of structural-constructive constitution of the image field and, at the same time, the impressive artistic expressions, obtained after practicing mixed techniques, giving priority to the collage methodology. In the artist’s creation, both the conceptualization and aesthetic interpretation of the theme, as well as the way of operating with plastic means imminently contribute to the demarcation and supplementing of the semantic area of the work with high value expressions.
El viaje sin héroe del cine colombiano
Authors: Rivera-Betancur Jerónimo León
Published: September 2021

En este libro, el autor sugiere que una de las principales marcas de identidad del cine colombiano (y buena parte del latinoamericano) es la conexión entre fi cción y realidad, y cómo, ante una realidad caótica de valores invertidos, los personajes de las historias se ven limitados a actuar en un contexto que castiga la heroicidad. Este texto busca ser referente para otros estudios que en el futuro se realicen sobre el cine colombiano o sobre cinematografías con condiciones industriales similares, en el entendido de que conocer las representaciones audiovisuales de una nación puede ayudarnos mucho en el conocimiento de su realidad, pero la narrativa no puede desligarse del contexto de la producción. Cuando la relación entre la fi cción y la realidad es tan estrecha como en el cine colombiano, estudiar el cine es acercarse a la esencia de los acontecimientos y su impacto en el imaginario colectivo nacional.
Knowledge and Practices of Hypertensive/Diabetic Patients with Hyperlipidaemia in a Secondary Care Setting in Ebute Metta, Lagos State.
Authors:   Department of Clinical Pharmacy & Biopharmacy, Faculty of Pharmacy, University of Lagos, Idiaraba Campus, Idiaraba, Lagos., Akinyemi E.I. , Aina B.A,
Published: September 2021

Background: Hypertension and diabetes are two chronic medical conditions which require aggressive management. When both diseases coexist with hyperlipidaemia, it poses a greater risk for cardiovascular disease than with either of the diseases alone. Self-management, a pillar of chronic disease management, is unachievable if patients are unaware or inadequately informed about their medical condition. Adequate information about a disease and its management will empower patients to manage their medical conditions better Objective: To assess hyperlipidaemia knowledge and practices among hypertensive/diabetic patients with hyperlipidaemia. Method: This study was conducted in a secondary healthcare facility in Lagos State. A cross-sectional study design was used. Data collection was done using researcher-administered questionnaires. An educational intervention was thereafter carried out. Verbal feedback on impact of intervention was received from all respondents. Frequency distribution and cross tabulations were generated using SPSS version 23.0 at significance level set at p<0.05. The knowledge-related questions were scored and converted to percentages. Scores below 50% were considered poor, while scores of 50 % and above were considered good. Results: The overall knowledge scoring revealed that more than half of the patients had poor knowledge of hyperlipidaemia. A significant association was observed between gender and knowledge of hyperlipidaemia (p<0.05); males having better knowledge. Patients had good practices such as good level of medication adherence and appropriate dietary and lifestyle choices necessary for effective hyperlipidaemia management. Conclusion: This study showed that knowledge of hyperlipidaemia is poor in this patient population, especially among the females though patients emonstrated good hyperlipidaemia practices.

Necessary Compromises: A Defense of Sympathetic Readings and Progressive Potential in Oliver Twist
Authors: Long Alexander
Published: September 2021

The field of literary study is perceived by some to be disproportionately represented by negative or critical analysis of canonical literature on the grounds that it has significant flaws when judged by today's standards. Though such criticism is necessary and important, this article reengages the progressive potential, that is to say the lessons of the text that offer hope for positive social change, in Dickens's Oliver Twist. Slavoj Žižek's theorization of violence is deployed as a method of engaging Oliver Twist with an eye toward systemic (i.e., objective) violence, and this focus is then leveraged to analyze the progressive elements of the novel more broadly, emphasizing how the minor characters, double-speak, and capitalistic language are all highly constructive in unpacking the complex social relations and progressive message that underlies the text's seemingly bourgeois façade. Ultimately, this close reading serves as a larger call to action that champions optimistic and sympathetic readings of popular texts in order to situate literary studies more generally as a force for social improvement in society.

All kinds of micro- and macroorganisms live in the massifs of clay soils: plants living in (or on) clay soils are called pelitophytes (from the Greek πηλός - “clay” and phyton - “plant”), micro- and macroorganisms living in clays, or associated with clays, they are called pelitophiles (from the Greek πηλός - "clay" and φιλία - "love"), that is, "loving clays" or "prone to clays." The article analyzes these groups of organisms and describes their role in the formation of the properties of clay soils and ecological-geological systems.
Regular Exercise, Thombocyte, Collagen and Breast Cancer
Authors: Vardar Tonguç , Türkay , İbrahim Kubilay
Published: September 2021

Platelets, which play a very important role in the continuation of vital activities, play an important role in blood coagulation. Various chronic diseases can reduce the platelets produced by our body below the standard level or increase them in a dangerous way. Diseases related to malignancy, that is, malignant tumors, come at the beginning of the diseases that disrupt the platelet balance. One of them is breast cancer. Breast cancer is a type of cancer that occurs as a result of mutations in the BRCA1 (17q21) and P53 (17p13) genes located on the 17th chromosome and the BRCA2 gene located on the 13th chromosome. It is known that the amount of bone mass due to estrogen hormone is closely related to the formation of breast cancer. Collagen is the protein that forms bones, cartilage fibers and joints, which are the building blocks of our motor (movement) system. The main protein that forms the main structure of the bone is Type I collagen and about 30 types of collagen have been defined. It acts as a support for bone and cartilage tissue. Regular exercise, on the other hand, is a type of regular, systematic and programmed physical activity done with the aim of improving the physical and mental state of the person. There are many studies that found that exercise increases the tendency of platelet aggregation (aggregation, aggregation, aggregation). In addition, there are scientific studies that show that regular exercise and regularly used collagen stop the progression of breast cancer. The aim of this scientific review is to describe the relationship between platelet, collagen, breast cancer and regular exercise.

Aim: The recent pandemic has spread all over the world and has become a common global problem. Pandemics leave significant marks on the memories. Going beyond a cause of disease or death, they can have consequences in many aspects; social, physical, and psychological. Aim of this study is to investigate the impact of the pandemic period on students’ loneliness and digital game addiction levels. Methods: The study group consisted of 398 volunteer 5th-8th grade students from Altın Vuruş Karate Center and Defne Middle School in Hatay, Turkey. As data collection tools, "Digital Game Addiction Scale" developed by Lemmens et al. (2009), and "UCLA Loneliness Scale" developed by Russell et al. (1980) were used. The SPSS program was used for the analysis of the data. Results: According to research findings, it was found that there was a statistically low positive correlation between digital game addiction and loneliness (p=0.002, r=0.155). The game addiction and loneliness level of students increased during the Covid-19 pandemic (p<0, 05). As the age of students increases their level of addiction also increases (p<0.05). Conclusion: Being a licensed athlete didn't have significant effect on the game addiction level of students during the Covid-19 period (p>0, 05), however they felt more lonely during the period (p<0.05).

Authors: Atli Ahmet , Yarar Ali Furkan
Published: September 2021

Background and Study Aim: This single group pre- and post-test study aimed to examine kinematic changes in vertical jump performances before and after fatigue in basketball players. Material and Method: Ten male university student (age 23.28±1.31 years, height 181.17±6.87 cm, body weight 74.53±9.27 kg) basketball players voluntarily participated in the study. Vertical jump test was performed twice, once before fatigue and again after fatigue, and jump measurements were recorded with 2 cameras capable of shooting 240 frames per second. The vertical jumps were measured using a Smart Speed device. The recorded measurements were analyzed using a biomechanical analysis program, and the results were analyzed statistically. Each participant performed 5 resting jumps on the jump mat after warm-up, and the highest height reached was determined as the jump height. Next, the protocol for inducing fatigue was initiated without a period of rest, and the participants were asked to sprint 6x10 m, following which vertical jumps were performed 5 times without any break. The maximum value of each parameter obtained from among the 5 vertical jumps was used for analysis. The protocol for inducing fatigue was followed until the post-fatigue vertical jump parameter values were below 70% of the maximum values recorded before fatigue. Pre- and post-fatigue jump parameter values were statistically analyzed using the paired samples t-test. Results and Conclusion: Statistically significant differences were observed in knee flexion angle measurements before and after fatigue as well as in jump height measurements before and after fatigue (p<0.05). Therefore, it is believed that fatigue may be associated with a risk of knee joint injury in basketball players. Keywords: Kinematic Analysis, Vertical Jump, Performance, Fatigue, Basketball Players

The causal screening model was used in the study, and a total of 67 athletes from 3 teams in the Turkcell Super League participated. The names of the teams are coded as Team A, Team B and Team C. Data collection was performed using SensorMedics 29 c ergospirometry with the breath by breath method of maximal oxygen consumption. Heart rate values were recorded instantly using Polar watch. The V-Slope method was used for the anaerobic threshold value. While SPSS 25.0 package program was used for statistical evaluation, One Way ANOVA analysis was applied to compare 3 teams. As a result of the statistical evaluation, it was determined that there was a statistically significant difference between the teams in endurance training (heart rate), anaerobic threshold (heart rate), recovery (heart rate), and interval training (heart rate) parameters, however there was no statistically significant difference between the teams in VO2max values. As a result, although there is no statistically significant difference between the VO2max values between the teams, it is concluded that the athletes with higher values are more advantageous in other parameters.

Aim: This study assessed the effect of beetroot juice supplementation on the dynamic and static balance performance of wrestlers at rest and fatigue conditions. Material and methods: The study was conducted with 3 trial days. The study is a double blind, randomized, cro ssover design in which eight trained male Greco Roman wrestlers (age 21.87±2.3 years; height 176.87± 4.1 cm; body weight 76.75± 5. 4 kg) consumed beetroot juice (BRJ) (140 ml) or placebo (PLA) (140 ml, cherry juice with lemon juice) 150 min before performin g balance performance test. Subjects were administered standard warm up and then dynamic and static balance tests were performed to the dominant leg with by Biodex Balance System (BBS, Biodex Medical Systems Inc., Shirley, NY) at rest. Following balance te sting, each subject got into a fatigue strength exercise (FSE) to create fatigue for the dominant leg. Immediately after the ( FSE), subjects were applied to dynamic and static balance test to the dominant leg again at fatigue. The same trial procedure was repeated with the other supplement (BRJ or P LA ) in the third testing trial five days later. Paired sample T test was used for comparison of BRJ and P LA balance performance values. Result: Although there were no significant changes in static OSI, APSI balance scores, Static MLSI improved significantly in favor of BRJ in rest . Dynamic OSI and APSI paramet er s improved significantly but not MLSI in the BRJ trial. While all static and dynamic b alance parameters improved statistically, only static MLSI w as not changed by the BRJ trial at fatigue. Conclusion: Consuming BRJ can be useful to maintain balance performance and prevent sports injuries in training or competition. Keywords: Beetroot Juice, Dietary Nitrate, Balance, Wrestlers.

Background: The Focusing the attention during the preparation period undergone immediately before carrying out a motor performance is vitally important for success. Visual ability, Quiet Eye and focusing the attention on the appropriate area play a critical role in achieving successful performance in branches of sport. Quiet eye (QE) is defined as the final fixation of the pupil on a location or object for a specific motor task. Aim: The aim of this study was to examine the durations of effective and final focusing (quiet eye) carried out during the process of taking aim at the target by air pistol shooting athletes with their eyes immediately before taking a shot. Methods: A total of 8 right-handed male licensed pistol shooting athletes (4 novice and 4 elite) participated in the research. A total of 320 shots -160 dry (unscored) and 160 live (scored) shots were taken by the novice and elite athletes. For the purpose of recording pupil movements and quiet eye durations during the shots taken by the athletes, an eye-tracking device attached to the head was used. The recorded data were examined with iMotions computer software, which can perform biometric analysis. The athletes’ quiet eye durations occurring when taking aim at the target were examined according to athletes’ characteristics (novice and elite) and the type of shot carried out (scored and unscored) by means of the independent samples t-test. Results: The findings of the study revealed that the athletes had 25.3% longer quiet eye durations when firing scored shots than when firing unscored shots (p = .000). Especially, novice athletes exhibited 37.8% longer periods of focusing behaviour when firing scored shots than when firing unscored shots (p = .000). Elite athletes displayed 21.26% longer periods of focusing behaviour when firing unscored shots compared with novice athletes (p = .005). Conclusion: According to the results of the research, it can be said that in the sport of air pistol shooting, giving priority to dry shooting training and conducting special exercises for developing quiet eye (QE) duration can contribute positively to the development of novice athletes’ shooting skills.

The aim of this study is to examine the relationship between academic self-efficacy and distance education perception levels of physical education and sports teacher candidates during the pandemic process. The population of the study consists of teacher candidates (n=908) studying at the physical education and sports teaching departments of the School of Physical Education and Sports and Sports Sciences within the private and public universities affiliated to the Higher Education Institution in Istanbul, and the sample consists of volunteers (n=398) determined by simple random sampling method from this population. In order to collect data, the Google Forms platform was preferred in order to maintain social distance during the pandemic process. During the data collection process, information and questionnaires about the study were communicated to the participants through social networks. Volunteers who participated in the study were asked to fill in the personal information form, academic self-efficacy and distance education perception scales. The data obtained in the study were analyzed in computer environment. Variables are expressed by using mean ± standard deviation, percentage and frequency values. Pearson product moments correlation analysis (r) was applied to reveal the relationships between the scales. For the significance level of the tests, p<0.05 and p<0.01 values were accepted. As a result, it was determined that the academic self-efficacy and distance education perception levels of physical education and sports teacher candidates were above the average. Between the academic self-efficacy and perception of distance education. A low level positive relationship was found. It is thought that this situation is caused by the concerns of physical education and sports teacher candidates, who are accustomed to the face-to-face transfer of knowledge and skills related to the teaching models of sportive skills, to the transition to distance education and to the problems that may occur in this process and not to learn the necessary knowledge and skills related to their professional development.

This research aimed to evaluate the management of a Sewage Treatment Plant (STP) and the existing biogas plant. A mathematical model was used to analyze the behavior of methane, biogas production and energy generation potential for a period of three years at the Jacuípe II Treatment Plant, located in northeastern Brazil. If the biogas plant were in operation, it would be possible to obtain autonomy for energy generation in the years 2016 and 2018. Greenhouse Gas Inventories - GHG, situational diagnosis of the biogas plant and scenario of financial losses with the deactivation of the plant were prepared. The results revealed that the emission of 1,958.38 tCH4 could have been avoided with the use of an energy generator (85% less than that emitted) or 1,151.99 tCH4 (50% less than emitted), if combustion by burner/flare. In addition, the financial loss due to the inactivity of the biogas plant resulted in US$ 154,162.38, about 67% of the actual energy expenditure of the plant in the period from 2016 to 2018. The reactivation of the biogas plant present in this station will bring environmental benefits, since the emission of GHG will be mitigated, in addition to financial benefits, since the energy use of biogas in the plant will provide a reduction in the expenses with electricity from STP Jacuípe II, in line with the aspects of sustainability.
