Unintentional disengagement is a factor in the failure of a final exam in a moderate-structure cell biology course
Authors: kramer ijsbrand , Pellerin frédérique , Bergey Jean-Luc
Published: March 2023

This study is situated in the problem of student retention in a first-year science course at a large, open-enrollment university. The study examines student performance in a moderate-structure cell biology course characterized by group classroom activities, frequent knowledge quizzes, a mid-semester exam, and a moderate impact final exam. The design is learning-oriented with a gradual transition from an external, instructor-based arrangement, to an internal, student-based arrangement. Although, consistent with numerous reports, we observe much better overall student performance in this course format, the improvement is largely due to scores on the quizzes and mid-semester exam, with little improvement on the end-of-semester final exam. Using self-reports, scores, and learning analytics from a population of 462 students, we sought to understand what factors contributed to this phenomenon. We found that despite good intentions, an awareness of essential cognitive skills, and an a priori appreciation of the subject matter, about a quarter of the students dramatically reduced their viewing of web-based learning materials in the period leading up to the final exam. This group scored well below average. We conclude that unintentional disengagement is a factor in failing the final exam.

Published: March 2023

The diversity of fruits and frugivorous species is especially high in tropical regions where frugivory and seed dispersal interactions are particularly critical for the structure and functioning of terrestrial communities. However, the increasing urbanization in tropical areas has caused profound landscape changes, affecting species interactions and associated ecosystems functions. Here, we present an overview of the studies on frugivory and seed dispersal in tropical urban areas, discussing emergent patterns and processes underlying plant-frugivore interactions as well as major research gaps. Our review highlights an uneven geographical distribution of studies, which are more frequent in the Neotropics in comparison to Indomalayan and Afrotropical regions. We found that in tropical urban areas: (i) the most frequently studied group are flying frugivores (birds and bats), (ii) fruits of Myrtaceae, Moraceae, and Arecaceae are most frequently reported as consumed by frugivores, (iii) introduced plants are often present in frugivores’ diets, and become more common with urbanization, (iv) frugivores niche breadths vary with seasonality in fruit availability, (v) a higher diversity of fruits are consumed by frugivores in (or near) habitats that preserve more natural characteristics, such as higher proportion of green areas. Since suitable habitats within cities are highly variable in size, shape, connectivity, patterns of human activity, vegetation management and socioeconomic contexts, we recommend future studies to sample gradients in such variables. Furthermore, as new urban areas are often planned in advance, ‘before-after impact’ studies may be particularly insightful to understand how frugivores respond to urbanization and how to create frugivore-friendly areas without promoting undesirable (invasive) plants. Although the scarcity of studies and their geographical bias limit generalizations across distinct tropical regions, based on our review we provide a preliminary list of broad recommendations of management practices towards creating biodiversity-friendly urban areas.
A Multivariate Meta-Analysis of the Effects of Business-as-Usual Special Education Services in U.S. Schools
Authors: Woods Adrienne D. , Gloski Cecelia , Wang Yangyang , Morgan Paul
Published: March 2023

Special education services provided in U.S. schools should be designed to enable students with disabilities (SWD) to make “appropriately ambitious” educational progress (Endrew F., 2017). Yet the field lacks consensus on whether business-as-usual (BAU) special education services effectively support outcomes for SWD. We conducted a moderated multilevel multivariate meta-analysis of 40 studies and 1,721 effect sizes from more than 14 million participants to evaluate the effectiveness of BAU special education services. Effects ranged from null-to-positive (z = -0.07 to 0.12) for achievement and negative-to-null (z = -0.13 to -0.01) for behavior. We observed positive outcomes for educational attainment including graduation outcomes (z = 0.12 to 0.24) and postsecondary outcomes (z = 0.10 to 0.23), as well as for other outcomes (z = 0.21 to 0.38). Studies that used a more rigorous research design or comparison condition reported more positive effects across outcomes. Additional casual work is needed in this field.
Memory reactivations during sleep: a neural basis of dream experiences?
Authors: Picard-Deland Claudia , Bernardi Giulio , Genzel Lisa , Dresler Martin , Schoch Sarah Fiona
Published: March 2023

Newly encoded memory traces are spontaneously reactivated during sleep. Since their discovery in the 1990s, these memory reactivations have been discussed as a potential neural basis for dream experiences. New results from animal and human research, as well as the rapidly growing field of sleep and dream engineering, provide essential insights into this question, revealing both strong parallels and disparities between the two phenomena. We suggest that while memory reactivations may contribute to subjective experiences across different states of consciousness, they are not likely to be experienced directly as dreams. We identify important limitations in current research paradigms and suggest novel strategies to address this question empirically.

The purpose of the work is to investigate the influence of kettlebell training on the formation of the physical readiness of cadets, future officers, to perform combat and other assigned tasks in accordance with the requirements of modern combat during training at a higher military educational institution. Future male officers of the 1st year of the Zhytomyr Military Institute named after S. P. Korolyov of the 2021 recruitment took part in the study, which was conducted during the academic year (n=50). To achieve the goal of the study, two statistically homogeneous groups were formed: experimental and control. The experimental group (EG) (n=25) included future officers who systematically engaged in kettlebell sports in the institute's section on kettlebell sports. Classes were held three times a week under the guidance of a trainer-teacher. The control group (CG) (n=25) included future officers who were additionally engaged in physical training in accordance with the Instruction on physical training in the system of the Ministry of Defense of Ukraine. Classes were held three times a week during sports and mass work hours under the guidance of a course officer. It was established that the level of development of physical qualities among future officers who engaged in kettlebell training during their studies at the higher military educational institution is significantly higher at the end of the study than among future officers who engaged in physical training in accordance with the Instructions in the system of the Ministry of Defense of Ukraine. The most pronounced impact of classes with kettlebell sports was found on the development of strength qualities and endurance of future EG officers.

Operating Surplus and its Importance in Financing Local Government Tasks on the Example of Municipalities of the Małopolskie Voivodeship
Authors: Wichowska Anna
Published: March 2023

The operating surplus is a positive subtraction result of the revenue and current expenditures of a local government units. The level of operating surplus determines the scope and quality of task implementation, as well as investment and development opportunities of a local government unit. In periods of economic slowdown, the surplus can serve as a kind of buffer and guarantee for the continuous and effective functioning of a local government unit. The aim of the research was to assess the operating surplus and the ability to perform local government tasks based on the balance of current revenue and expenditure in the current economic conditions. The analysis was carried out on the example of the municipalities of the Małopolskie Voivodeship in Poland, and the research period covered the years 2014-2021. According to the conducted research, the most dynamic situation in the operating surplus development took place in urban municipalities. These municipalities maintained the highest average level of operating surplus, but it was characterized by large fluctuations, e.g. in 2020 due to the Covid-19 pandemic. This may result from the fact of high budget revenues and the widest range of obligatory tasks, as well as from the sensitivity to economic changes of budget revenues that are significant in cities. As a consequence, the implementation of tasks in a continuous manner and at a constant level of quality in periods of downturn may be at risk in the case of these cities, and the lower level of operating surplus may force these local governments to incur liabilities.
Application of the 6D Hofstede Model in an Analysis of the Polish and Portuguese Business Culture
Authors: Siemiński Marek , Andruszkiewicz Katarzyna , Pinho Tiago
Published: March 2023

Business management in a culturally diverse environment, that is acting in different business cultures, is one of the major challenges facing managers nowadays. Cultural differences among societies have been known to exist for ages, but a holistic view of their impact on the business culture in particular countries, development of cultural typologies and studies into the nature of interactions between the business and organisational culture date back to the 1980s. The acceleration of social, technological and demographic changes, a more rapid process of globalisation as well as some disturbances, such as the COVID-19 pandemic, the war in Ukraine or the intensifying rivalry between China and the United States of America, increase organisational uncertainty. Such changes require a new cultural sensitivity as well as new, modified systems of values. The objective of this study has been to determine and compare the Polish and Portuguese business cultures. To this end, the contemporary Polish and Portuguese business cultures have been analysed according to the 6D Hofstede model.

Het Integraal Zorgakkoord (IZA) benadrukt een aantal uitdagingen voor de ggz, zoals de medicalisering van psychisch lijden, gebrek aan ondersteuning voor mensen in een sociaaleconomisch kwetsbare positie en beperkte toegang tot zorg. Een integrale samenwerking tussen alle stakeholders wordt aanbevolen. De regie wordt gelegd bij ggz kerninstellingen. Dit roept de vraag op of de ggz kerninstellingen, met hun (hoog) gespecialiseerde kennis op basis van het biomedisch model, de meest voor de hand liggende aanjagers zijn van de veranderde focus op mentale gezondheid. Om deze vraag te beantwoorden is (i) een analyse gemaakt van feedback loops binnen de ggz, evenals (ii) een analyse van Vektis-data en CBS-data naar de relatie tussen sociaaleconomische data en ggz-kosten op PC4-niveau en factoren die daarop van invloed zijn en tot slot (iii) een analyse van een aantal aspecten van het IZA, met name de integrale samenwerking en de werkagenda samenwerking van de ggz met het sociaal domein en de huisartsenzorg. Hierbij wordt inzichtelijk welke patronen de huidige problemen binnen de sector in stand houden en waar de mogelijkheden liggen om het anders te gaan doen. De analyse suggereert dat een transformatie nodig is die voorziet in een andere manier van kijken naar psychisch lijden en een sterke waardengerichte samenwerking van partijen, dwars door wetten en settings, in een flexibel ecosysteem van sociale, publieke en medische hulpverlening
Synergistic effect of turmeric (Curcuma longa L.) powder and nitrifying probiotics on productivity and ammonia level in excreta from quails (Coturnix coturnix japonica)
Authors: Al Jawawi Ahmad Junaidi , Kalsum Umi , Muwakhid Badat
Published: March 2023

One of the keys to successful quail rearing is choosing suitable nutritional feed. Unfortunately, feed nutrients not adequately absorbed by the digestive tract of quails, in addition to impacting productivity, will also be wasted and decompose to form ammonia, which becomes a supporting factor for disease. This study aims to determine how adding turmeric powder and nitrifying probiotics affect the productivity and amount of ammonia from quail excreta. The research design used was a completely randomized design (CRD) with 6 (six) treatments, i.e., control (without the addition of turmeric powder and nitrifying probiotics), the addition of nitrifying probiotics 4.5 g/kg of feed, the addition of nitrifying probiotics 6 g/kg of feed, the addition of turmeric powder 3 g/kg of feed, the addition of 3 g turmeric powder + nitrifying probiotics 4.5 g/kg of feed, and the addition of 3 g turmeric powder + nitrifying probiotics 6 g/kg of feed. Data were analyzed statistically using ANOVA and followed by the DMRT. The results showed that adding turmeric powder and nitrifying probiotics had no effect on feed consumption, feed conversion ratio (FCR), protein efficiency ratio (PER), and ammonia level in quail excreta but had a significant impact on quail day production (QDP). This study concluded that adding turmeric powder and nitrifying probiotics can improve the value of QDP, PER, and reduce ammonia levels in quail excreta but had not been able to enhance the value of feed consumption and feed conversion ratio.

Topicality. Adhesives are an integral part of the weed control system in the maize crops, because they increase the efficiency of herbicide application. They significantly reduce the cost of plant protection products and increase their efficiency, as well as increase the adhesive properties of the herbicide solution to prevent its runoff and prolong its action. Development of new herbicides, constant weather and climate changes require to study further the effectiveness of the combined action of herbicides and adhesives. Among the adhesives for maize, it is generated interest such products as Synergent SOC, Eco Oil Spray, Esterlip, etc. Purpose. To reveal the effectiveness for combinations of herbicides with adhesives in the maize crops, as well as their impact on plant growth and development. Materials and Methods. The experimental scheme included the following combinations of rimsulfuron with adhesives: 1. Control (Rimsulfuron without adhesive); 2. Rimsulforon (40 g/ha) + Trend 90 (0.15 % working solution); 3. Rimsulforon (40 g/ha) + Synergent (0.15 % working solution); 4. Rimsulforon (40 g/ha) + Eco Oil Spray (0.15 % working solution); 5. Rimsulforon (40 g/ha) + Esterlip (0.15 % working solution); 6. Rimsulforon (35 g/ha) + Esterlip (0.15 % working solution); 7. Rimsulforon (25 g/ha) + Esterlip (0.15 % working solution). Results. The combination of rimsulfuron with adhesive Esterlip had the highest technical efficiency compared to other adhesives, in particular, on the redroot pigweed (Amaranthus retroflexus L.) was 75–100% (complete destruction) and lamb’s quarters (Chenopodium album L.) – 85.7–92.9 %, slightly less on common ragweed (Ambrosia arte-misiifolia L.) – 83.3%. Common purslane (Portulaca oleracea L.) was highly resistant to almost all combinations of rimsulfuron with adhesives. The highest maize yield of 8.99 t/ha was in the variant with Rimsulfuron (40 g/ha) + Esterlip. Reduced application rate of Esterlip to 25–35 g/ha decreased the maize yield to 7.34–7.65 t/ha, or by 1.34–1.65 t/ha (14.9–18.3 %) due to increased weed infestation of crops. The application of adhesives Trend 90, Synergen, Eco Oil Spray also decreased maize yields to 8.48 t/ha, 8.07 t/ha and 8.62 t/ha, respectively, which was less by 0.51 t/ha (5.6 %), 0.92 t/ha (10.2 %) and 0.37 t/ha (4.1 %). The lowest yield was in the control – 5.30 t/ha due to significant weed infestation of grain crops, which decreased by 3.69 t/ha (41.0 %) compared to the best variant (Rimsulfuron (40 g/ha) + Esterlip). Conclusions. Considering the ongoing development of new adhesives and herbicides for maize, as well as climate changes, it is necessary to continue research in this area to determine the most optimal ratio of herbicide rates with adhesives. Key words: maize, weeds, herbicides, adhesives, yield, technical efficiency

Topicality. Changes in weather and climatic conditions affect the formation of pathogenic complexes of grain agrocenoses and the species composition of pathogens, which are typical for the Steppe zone of Ukraine. At the same time, changes in cultivation technologies accompanying the transition to new forms of management also play a significant role in the formation of pathogenic complexes. It is necessary to find out the features of the pathogenic mycoflora formation and plant immunity in order to scientifically substantiate measures to stabilize the phytosanitary state of agro-cenoses at the current stage of grain production. Purpose. To divide into appropriate groups of grain crop diseases in the Steppe zone in terms of the nature of development, harmfulness and hy-drothermal dependence of their pathogens. Materials and Methods. In 1999–2019, we conducted surveys of wheat (winter and spring), rye, barley (winter and spring), oats and maize for disease in-festation in the Northern Steppe of Ukraine according to generally accepted methods of phytopathological research. Results. Over the years of research, we identified 123 pathogens, which caused 135 diseases in grain crops. The most diverse composition of pathogens was observed on wheat and maize, 64 and 55 pathogens, and, 33 and 41 diseases, respectively. It should be noted a wide range for specialization of the widespread pathogens in the Northern Steppe of Ukraine. The pathogens of smut infects generally a certain type of grain crops, rusts are somewhat less specialized. Less specialized parasites, such as fungi from the genera Fusarium, Helminthosporium, Alternaria cause the same type of diseases in several plant species, and some of them affect different plant organs. Thus, among the pathogens of Fusarium root rot of wheat, rye, barley and maize, the fungus Fusarium moniliforme Sheld. was identified. On the maize, in particular, this pathogen caused seedling mold, root and stem rot, cob rot, and grain mold. Conclusions. It was established that the hydrothermal regime can affect the development of diseases not only due to its compliance with the pathogen's requirements, but also affect the resistance of plants. The problem of agrocenosis recovery can be successfully solved by adapting modern intensive technologies of growing grain crops that aimed to optimally utilized ecological resources by plants in the Steppe of Ukraine, and prevent the spread of harmful organisms. Key words: winter wheat, maize, pathogens, diseases, hydrothermal conditions, harmfulness
Influence of tillage and fertilizers on the weed infestation of field crop rotation link in the Northern Steppe of Ukraine
Authors:   Luhansk Institute of Agro-Industrial Production of the National Academy of Agrarian Sciences of Ukraine, Medvediev E. B.
Published: March 2023

Topicality. In the current conditions in Ukraine, the issues of weed control in crops do not lose their relevance due to the negative processes caused by the aggravation of the economic situation, the rapid soaring prices on mineral fertilizers, machinery, fuels and lubricants, plant protection products, the replacement of energy-intensive traditional tillage systems with moldboardless and other resource-saving ones. Purpose. To study the influence of tillage and fertilizers on the weed infestation of agricultural crops in the link of the field grain-fallow-row crop rotation: winter wheat after maize (milk-wax ripeness) – grain peas – winter wheat in the Northern Steppe of Ukraine. Materials and Methods. Methods of tillage with applying mineral fertilizers under the primary tillage were tested. The field and statistical-mathematical methods were used in experimental studies. The number of weeds in crops was determined by the quantitative-weight method using square frames. Results. It was established that moldboardless tillage in the crop rotation link against the background of plowing under maize and harrowing with light harrows during the growing season leads in comparison with moldboard tillage to the following increase in weed infestation – on average for years of research: annual weeds during the growing season: in peas crops – by 40.6 (without fertilizers), 44.2 (with recommended dose) and 51.6 (with calculated dose) pcs/m2; before harvesting: by 22.7, 24.4 and 36.4 pcs/m2, respectively; in winter wheat crops after peas – by 0.5, 11.9 and 19.4 pcs/m2; 5.8, 8.4 and 6.7 pcs./m2, respectively; perennials in winter wheat crops after peas during the growing season: by 10.4, 9.1 and 10.9 pcs/m2; before harvesting: by 19.1, 18.3 and 20.0 pcs/m2, respectively. The application of mineral fertilizers increases germination of annual weed seeds. This was most clearly observed in winter wheat crops after maize of milk-wax ripeness. A tendency towards an increase in the air-dry weight of weeds under fertilization was revealed for all crops in the crop rotation link. Conclusions. Moldboardless tillage increases the number of weeds, but does not increase their air-dry weight, and decreases grain yield and quality. Mineral fertilizers applied in the experiment increase the air-dry weight of weeds and the number of their annual species. The species composition of weeds in the crops did not depend on the method of tillage. Key words: weeds, tillage, mineral fertilizers, winter wheat, peas

The 2022 Stockholm+50 Moment in the Era of a Planetary Crisis: Some Lessons for the Scholars and the Decision-makers
Authors: Desai Bharat H.
Published: March 2023

The Stockholm+50 Conference (2-3 June 2022) has been perceived as a low-key affair and a missed opportunity. The moral halo that ushered the world into global environmental consciousness, led by the Prime Ministers of Sweden (Olof Palme) and India (Indira Gandhi) at the first UN Conference on the Human Environment (UNCHE) held in Stockholm (5–16 June 1972) seemed to be missing at the 2022 Stockholm+50 Conference. This historic event coincided with the 30th anniversary of the UN Framework Convention on Climate Change (UNFCCC). The Stockholm+50 event, jointly hosted by Sweden and Kenya, ended as a ubiquitous joint Presidents’ Final Remarks to the Plenary issued by the two host countries. In spite of the call for action by the UN Secretary-General Antonio Guterres to address the “triple planetary crisis” driven by climate emergency, biodiversity loss and pollution and waste, the Stockholm+50 outcome took the shape of ten-point summarized recommendations. It didn’t cause any ripples or resulted in a clarion call that could shake the conscience of peoples and nations to arise for everting the existential planetary crisis. The 2022 Stockholm+50 Moment at best remained a timid acknowledgement of things going terribly wrong in the past fifty years (1972–2022). Yet, no world leader stepped forward to don the mantle “to rescue” the world from the “environmental mess” as urged by the UNSG in his 2 June 2022 inaugural address. The heads of government and delegations seemed to lack the requisite courage befitting the momentous occasion for a decisive course correction in the global environmental regulatory policies, legal instruments and the environmental governance architecture. What would it entail to address the planetary crisis? It brings to the fore some lessons from the 2022 Stockholm+50 Moment that presents an ideational challenge for scholars of International Law and International Relations as well as the UN system, multilateral environmental treaty processes, international institutions and the decision-makers of the sovereign states.

In Present days, one of the most appealing technologies is cloud computing in the current time. Now a day, different organizations are offering various cloud services concerning their platforms. These organizations are profitable in cost-efficiency to the end-users in various factors that include process, storage, and applications instance. Most of the end-users choose the services from the cloud service provider, whereas some medium-scale organizations are also depending on the service providers even though they have enough resources. This causes the problem due to a lack of knowledge on design and deployment issues. In this paper, we proposed a private cloud that offers cloud services with limited resources so that small and medium scale organizations can be benefited. In this work, we proposed a novel three tier architecture that contains Domain Controller (DC), Virtual Machine Manager (VMM), and Member Servers (MSs) at a different level of functioning and also have their responsibilities. In this Novel three tier architecture was designed in a hierarchal fashion in which the upper layer accesses the lower layer users. The top layer, which deals with the domain controller whose responsibility, is to control the domain-specific issues like adding the member in the network, granting permissions, creating network groups, etc. The middle layer has various administrative users like Virtual Machine Manager (VMM), Storage Area Network (SAN), Disaster Recovery (D/R), and Operational Manager (SCOM), which deals with their responsibilities in cloud services. In the bottom layer, the physical servers exist and are configured by DC and get access by the middle layer users. This architecture was tested with various applications with different instances concerning storage and process utilities.

O médico de família (MF) é responsável pela prestação de cuidados continuados longitudinalmente, estando na posição ideal para prestar cuidados paliativos (CP), visto que possui uma relação de confiança e proximidade com o doente/família. Alguns fatores condicionam a prestação de CP pelo MF, como a falta de formação, de tempo e de normas de orientação clínica. Na prática, o MF pode hesitar relativamente ao melhor método a seguir nas situações de CP. Propõe-se um método que visa estruturar a atuação do MF durante as visitas domiciliárias – o método ACERTAR, acróstico que congrega os sete objetivos (e intervenções decorrentes) da prestação de cuidados domiciliários: Avaliar; Comunicar; Empoderar; Rever/Reduzir; Tratar; Antecipar e Referenciar. O MF tem um papel vital no acompanhamento dos doentes com necessidades paliativas. Pretende-se, assim, divulgar um guia que possa ajudar o MF na prestação de cuidados aos utentes com necessidades paliativas.
ОСОБЛИВОСТІ ЗМІСТУ І РОЗВИТКУ ПРОФЕСІЙНОЇ КОМПЕТЕНТНОСТІ ОФІЦЕРІВ ДЕРЖАВНОЇ ПРИКОРДОННОЇ СЛУЖБИ УКРАЇНИ НА ОПЕРАТИВНОМУ РІВНІ ВІЙСЬКОВОЇ ОСВІТИ

У статті представлено узагальнення міркувань щодо підготовки офіцерських кадрів для ДПСУ, шляхів розвитку професійної компетентності офіцерів-прикордонників та її змісту на оперативному рівні військової освіти з урахуванням національних особливостей вищої військової школи і науки. З’ясовано, що нині спостерігається наявність низки проблем і невідповідність системи військової освіти України новими викликам, які постали перед українським суспільством та її Збройними Силами. Про це свідчать результати узагальнення положень нормативно-правових документів, що регламентують окремі аспекти військової освіти та науки, а також узагальнення зарубіжного досвіду розвитку військової освіти в країнах-членах НАТО, світові тенденції модернізації військової освітньої галузі. Наявність проблем вимагає оновлення змісту військової освіти, застосування нових підходів до формування результатів навчання здобувачів військової освіти, структури та змісту професійної компетентності офіцерів тактичного й оперативного рівнів з метою забезпечення сил сектору безпеки і оборони України вмотивованими і професійними військовослужбовцями, досягнення оперативної й технічної сумісності зі збройними силами держав-членів НАТО. З огляду на це професійну військову освіту пропонується будувати за новою структурою, яка передбачає запровадження багаторівневої системи L-курсів для офіцерського складу. Подібний підхід до організації навчання на L-курсах поширений у навчальних закладах країн-членів НАТО. У процесі вдосконалення процедури і змісту військової освіти в контексті реалізації стандартів НАТО важливе значення має врахування особливостей функціонування окремих сил сектору безпеки і оборони, зокрема Державної прикордонної служби України, яка є правоохоронним органом спеціального призначення, що реалізує державну політику у сфері безпеки державного кордону України. Що стосується змісту оперативного рівня військової освіти, то головним завданням відповідного L-курсу є розвиток у слухачів лідерських та управлінських компетенцій, що мають бути притаманні керівникам оперативного рівня. Це пропонується досягти шляхом поглиблення або набуття професійних компетенцій (знань, умінь і навичок), а також ознайомлення з основними теоріями та моделями військового лідерства. Розвиток професійної компетентності офіцерів-прикордонників залежить також від практики застосування сучасних систем імітаційного моделювання, що призначені для імітації управління військами та ведення операцій, імітації умов реального бою, збройного зіткнення підрозділів, відпрацювання заходів з планування та проведення бойових дій, а також проведення командно-штабних навчань та військових операцій.

Fluoxetine is a Selective Serotonin Reuptake Inhibitor (SSRI) that exerts its anti-depressive effect by blocking the presynaptic reuptake of the neurotransmitter serotonin, 5-hydroxytryptamine (5-HT). Although fluoxetine is usually considered safe for most patients, in the present case report, we describe a young patient with Mixed Anxiety and Depression Disorder (MADD) treated with fluoxetine 10 mg/day, who developed hypotension when the dosage was titrated up to 20 mg/day. After discontinuing the use of fluoxetine, the symptoms of hypotension improved. A temporal association and dose-dependent relationship between the hypotension and the use of fluoxetine was observed. To the best of our knowledge, this is the first case report that precisely associates regular doses of fluoxetine with the presence of hypotension. Because boosting central serotonergic function lowers blood pressure, it is suggested that a significant effect of fluoxetine on the vasomotor center may be responsible for the reduction of blood pressure. Thus, physicians should be aware of the possible risk of hypotension induced by fluoxetine and recommend patients discontinue the drug immediately if complications have occurred.

Background: Oxidative stress may be a causative factor for bisphenol A (BPA) -induced hepatotoxicity. Glutamine (GM) is an amino acid with the ability to inhibit oxidative stress. Objective: This study evaluated the ability of GM to prevent BPA-induced hepatotoxicity in rats. Methods: Adult Wistar rats of both sexes (n=30) were used. The rats were randomly grouped into six of five rats each. Groups A (Control), B, and C were treated with normal saline (0.2 mL), GM (80 mg/kg), and BPA (50 mg/kg), respectively for 60 days. Groups D-F were treated with GM (20 mg/kg)+BPA (50 mg/kg), GM (40 mg/kg)+BPA (50 mg/kg), and GM (80 mg/kg)+BPA (50 mg/kg), respectively for 60 days. After treatment, blood and liver samples were obtained for biochemical and histological assessments, respectively. Results: Significantly (P<0.01) decreased body weight and significantly (P<0.01) increased liver weight occurred in the BPA-administered group when compared to the control group. The BPA-administered group showed significantly (P<0.001) elevated serum total bilirubin, lactate dehydrogenase, aminotransferases, conjugated bilirubin, gamma-glutamyl transferase, alkaline phosphatase, and liver malondialdehyde concentrations when compared to the control group. Significantly (P<0.001) decreased liver superoxide dismutase, glutathione peroxidase, catalase, and glutathione levels occurred in the PBA-administered group when compared to the control group. BPA caused hepatocyte necrosis, sinusoids, and central vein congestion. BPA-induced hepatotoxicity was reversed by GM; 20 mg/kg (P<0.05), 40 mg/kg (P<0.01), and 80 mg/kg (P<0.001) in a dose-related fashion when compared to BPA. Conclusion: GM may be effective against BPA-associated hepatotoxicity.

Background: Psidium guajava (guava tree) is widely used in Nigeria to treat diseases. However, a paucity of information exists on the safety of the plant. Objectives: This study determined the safety of P. guajava leaves collected in Birnin Kebbi, Nigeria. Methods: The methanolic extract of the plant’s leaves was subjected to phytochemical and heavy metal screening using standard protocols, and thereafter, subjected to a cytogenetoxicity test using the Allium cepa toxicity assay. Twenty-one A. cepa bulbs divided equally into seven groups were grown over beakers containing distilled water (negative control), formaldehyde (positive control), as well as 0.25, 0.5, 1, 2, and 4 g of the extract, respectively, for five days. The root-tip cells of the A. cepa bulbs were treated and then examined for chromosomal aberrations. Results: The phytochemical screening revealed high levels of saponins, and moderate levels of phenols, tannins, and flavonoids, while quinones and terpenoids were sparingly available. The heavy metal analysis showed non-permissible levels of cadmium and zinc, while two other tested heavy metals (lead and copper) were undetected. Except for the A. cepa treated with 0.25 and 0.5 g, the extract induced dose-dependent root growth and mitotic index inhibition (P<0.05). The extract also induced cytogenetic effects, mainly sticky, vagrant, and fragmented chromosomes as well as anaphase bridges. Conclusions: It can be inferred from the results that low to medium doses of the extract are safe but may elicit harmful effects at high doses. Advice from a phytomedicine or phytotherapy expert should be sought before using it.

Introduction. The quality of input information for trajectory processing (TP) systems can be improved by increasing the measurement accuracy of radar sensors (RS). However, in such a case, radar targets acquire the characteristics of complex targets having several marks at the output of the detector. This makes it difficult to accurately assess the kinetic parameters of targets in a TP system. In this respect, the development of a generalized algorithm for processing and generating data from the reflected signals of complex targets seems a relevant research task.

Aim. To investigate reasons for the formation of complex targets and, using the theory of radar image processing, to synthesize an algorithm for processing and generating data on reflected signals from a complex target.

Materials and methods. The following methodological approaches were used: the theory of digital signal processing; applied theory of radar image processing; MATLAB Simulink Toolboxes for simulating radar image processing; some prerequisites for fuzzy clustering methods.

Results. Following an analysis of some characteristics of complex targets and the theory of radar image processing, an generalized algorithm was synthesized for processing and generating data of reflected signals from this class of targets. The results can be used to improve the measurement accuracy of their representative point when solving the TP problem.

Conclusion. Reasons for the formation of complex targets in radar technology were analyzed. Their specific features consist in the need to accurately assess a true mark. A generalized algorithm for processing and generating these signals reflected from complex targets was proposed. The results can serve as a basis for solving the TP problem.
