Отношение к власти как фактор восприятия политического троллинга в российских социальных медиа
Authors: Стукал Денис , Шилина Анна
Published: July 2022

Политический троллинг в социальных сетях превратился в последние годы в новую технологию цифровой политики. Исследования троллинга в политической науке, однако, фокусируются на проблеме детекции троллей и описании характера их деятельности и стратегий, во многом игнорируя вопрос о восприятии троллинга пользователями. Результатом такого смещения академической оптики является острая нехватка работ о последствиях и результатах политической онлайн-активности троллей. Методологически ситуация усугубляется тем, что существующие исследования опираются на выявление троллей путем ручной разметки пользователей социальных сетей. Игнорирование вопросов восприятия троллинга в этой ситуации может приводить к систематическим смещениям в эмпирических результатах. Авторы данной работы стремятся заполнить отмеченный пробел в научной литературе, исследуя восприятие политического троллинга в социальной сети “ВКонтакте”. С опорой на литературу, посвященную феномену селективного восприятия, в статье выдвигается гипотеза о том, что сторонники и противники действующей власти будут чаще называть троллингом сообщения, выражающие противоположную политическую позицию. Эта гипотеза проверяется на основе анализа оригинальных эмпирических данных методами регрессионного анализа, который показывает, что лишь одна из рассматриваемых групп респондентов – оппозиционно настроенные респонденты – склонна чаще маркировать в качестве троллинга сообщения с противоположной политической позицией. При этом сторонники действующей власти не демонстрируют систематических различий в восприятии провластного и оппозиционного троллинга. Полученные результаты, с одной стороны, указывают на методологические ограничения эмпирических исследований, опирающихся на размеченные данные; с другой – указывают на значимые различия в восприятии политической онлайн-информации сторонниками и противниками действующей власти и актуализируют проблематику базовых политических представлений в исследованиях политической коммуникации.

First record of Pistia stratiotes L. (Araceae) in Croatia, with the consideration of possible introduction pathways
Authors: Boršić Igor
Published: July 2022

Background and Purpose: The species Pistia stratiotes L. (Araceae) is South American (or pan-tropical) free-floating, aquatic macrophyte, present on all continents, except Antarctica, today. In Europe it occurs occasionally and casually in many countries, but it is established only in thermally abnormal waters in Slovenia, France and Germany. Although it was found in different European countries, even in Slovenia, it has never been recorded in Croatia. Materials and Methods: Floristic research in the Sava-Strmec Special reserve (Zagreb County) was carried out during autumn (September and November) of 2017, using GPS Receiver to determine investigated localities. Results: The species Pistia stratiotes was firstly recorded on 9th September 2017 on one locality in the Sava-Strmec Special reserve (Zagreb County). On 24th and 27th November 2017 several other localities in the vicinity were found. On each locality a small colony of plants was found. Although exact introduction pathway is not known, several possible pathways were taken into consideration and discussed. Conclusion: A first record of the macrophyte Pistia stratiotes for Croatia is reported here. For now, it should be treated as a casual alien species.
Submandibular region Schwannoma: A case report
Authors: Sheikh Rayees Ahmad
Published: July 2022

Approximately 25-40% of the total schwannomas, are head and neck Schwannomas, they may originate from nerve sheath of the peripheral, cranial or autonomic nerves. We report a case of Schwannoma of right side Submandibular region in a 25 year old female with no significant dental, personal or medical history. Schwannomas are slowly progressive benign lesions, the patient presents with a mass or swelling that is growing in size slowly. The lesions are usually painless non-tender, smooth swelling beneath the mucosa with no changes in the overlying skin. An Ultrasound revealed well circumscribed hypoechoic solid lesion with internal vascularity. The lesion on T1 weighted MRI images exhibits homogenous isointensity and on T2 weighted MRI images exhibits heterogenous hyperintensity on contrast enhanced T1 MRI images it exhibits salt and pepper type of enhancement. The diagnosis of Schwannoma is confirmed histopathologically by showing the presence of Antoni type A cells and Antoni type B cells, nuclear palisading, whirling of cells and Verocay bodies. This tumor may have originated from an autonomic nerve of the submandibular gland.
Sustainable growth and the role of artificial intelligence in improving circular economy
Authors: Amatucci Carlo
Published: July 2022

Sustainable development has three dimensions, economic, social and environmental. The three-fold dimension of sustainable development implies the consideration of the environmental issue that goes beyond mere protection of the environment since it cannot be considered separately from the economic-productive system and social needs. The circular economy operates along the same three dimensions. A central role in the successful implementation of the circular economy must necessarily be given to the enterprises. Artificial intelligence provides a powerful tool in the transition to a circular economy, acting as an instrument for innovation in the business model, by directing business activity towards sustainable capitalism, overcoming the model of capitalism aimed solely at profit.

Authors: Hoogland Romy , Hoogland Lisa , Handayani Krisna , Sitaresmi Mei , Kaspers Gertjan , Mostert Saskia
Published: July 2022

Background: Physician dual practices (PDP) is a term used to describe physicians who combine work in public and private health-care sector. This study aimed to find evidence of PDP worldwide, investigate its reasons and consequences, and compare high-income (HIC) versus low and middle-income countries (LMIC).
Methods: In this literature review, the search for PDP evidence was conducted in the English language. PubMed and Google were searched for relevant publications up to Sep 30, 2020.
Results: Of 195 countries, PDP-reports were found in 157 countries (81%). No significant difference in prevalence of PDP was found between HIC (77%) and LMIC (82%). Most common reason for working in private sector was low government salaries in public hospitals (55%). This was more reported in LMIC (65%) than HIC (30%; P<0.001). Most common reason for working in public sector was patient recruitment for private practice (25%). This was more reported in HIC (45%) than LMIC (16%; P<0.001). PDP were described as detrimental to public health-sector in 58% of country-reports. Most common adverse consequence was lower quality-of-care in public hospitals (27%). LMIC with PDP-reports had more severe corruption (P<0.001), lower current health-expenditure (P<0.001), and higher out-of-pocket expenditure (P<0.001) than HIC. Scale of PDP was common in more LMIC (92%) than HIC (60%; P<0.001). Government policies to address PDP did not differ significantly between HIC and LMIC.
Conclusion: PDP were present in most HIC and LMIC. In majority of reports a detrimental effect of PDP on public health-care was described.

Published: July 2022

Background: Syphilis is one of the most important sexually transmitted infections (STI) and a public health problem, but the literature describing the true burden of syphilis is limited. In Iran, there are no accurate results on the prevalence of syphilis. This study aimed to conduct a systematic review and meta-analysis of syphilis in Iran.
Methods: Following PRISMA guidelines, we conducted a systematic review and meta-analysis of studies published on the prevalence of Syphilis in Iran. We systematically reviewed the literature to identify eligible studies as of Sep 13, 2020, in international and national databases. The results are presented in the form of forest plots and tables. Pooled prevalence and 95% confidence intervals were calculated using Der Simonian and Laird method. Perform subgroup analysis through population, gender, city, and diagnostic tests to assess the source of heterogeneity.
Results: We reviewed 1,229 papers and reports, and extracted data from 15 eligible records. The prevalence of combined syphilis in Iran is 0.1% (95% confidence interval [95% CI] 0.1-0.1%). The prevalence of syphilis was 0.4% in men (95% confidence interval [95% CI] -0.3, 1%) and 0.6% in women (95% confidence interval [95% CI] (0.1, 1%)). The cumulative meta-analysis showed a decline in the prevalence of syphilis between the years 1999 and 2015.
Conclusion: The prevalence of syphilis in Iran is low. In the past few decades, the prevalence of syphilis across the country has declined. Syphilis infection is a small burden that needs to be revised in the implementation of high-cost screening programs.

Authors: Alqahtani Taif , Konbaz Faisal , Aleissa Sami , Alhelal Fahad , Abalkhail Majed
Published: July 2022

Background: Herniated nucleus pulposus is infrequent among children and adolescents. The first case of surgical intervention for disc herniation was reported in a 12-year-old child. Since then, very few cases or series of cases have been published. The current case report is of a 15-year-old girl with no history of spinal ailment, who presented with a large disc herniation in the L4–L5 region, associated with reactive secondary scoliosis and resolved following a successful surgical intervention.
Case Description: A 15-year-old female with a known case of scoliosis and a history of lower back pain for nine months following a fall while playing football, without any past account of the spinal disease, was presented at the outpatient clinic. After a series of proper imaging, a large L4/5 HNP with positional secondary scoliosis was diagnosed. However, due to the persistence of symptoms for more than two months in radiculopathy and reactive scoliosis, the decision was made to proceed with L4/5 microscopic discectomy. After six months, the neurological examination was normal, with a significant improvement of scoliosis with the restoration of normal spine alignment seen in plain X-ray films. The right leg radiculopathy improved as well.
Conclusion: Lumbar disc herniation in association with scoliosis needs a vigilant evaluation of signs and symptoms and appropriate diagnostic imaging. Imaging is vital in diagnosing underlying disease states and helps in clinical management and surgical planning. The appropriate treatment is a discectomy.

Published: July 2022

Aim: The aim of this study was to investigate the role of mental disorders and resilience against suicide in a suicide attempt. This research is applied, in terms of purpose, and post-event in terms of type.
Methods: The statistical population of the study included all young men in Qazvin and the statistical sample included 80 of them who were purposefully selected and divided into two groups of suicide attempters and normal people. The Revised Mental Disorders Symptoms Checklist (SCL-90-R) and the Suicide Resilience Questionnaire (Osman et al., 2004) were utilized to collect data.
Results: The results showed that the mean scores of those who attempted suicide were significantly high on aggression, anxiety, obsessive-compulsive disorder, physical complaints, psychosis, paranoid delusions, depression, and morbid fear than normal individuals. Also, the mean scores of those who attempted suicide were significantly lower than the normal group in the overall score of resilience and internal protective subscales, emotional stability, and external protection (P<0.05).
Conclusion: Based on the obtained results, it is suggested to increase the resilience against suicide with psychological training and with interventions based on psychotherapy theories, to address mental disorders which played an important role in a suicide attempt in the present study, and as such to reduce the risk of suicide.

Published: July 2022

Aim: This study aimed to investigate the effect of applying the principles of Impact Therapy on problem-solving skills, hopefulness, and life satisfaction in teenage girls living in families with high tension. 
Methods: This research, in terms of purpose was an applied study using the pretest-posttest control group method. From the community of the 16 to 18-year-old girls from currently divorced parents who had referred to the court during the past 5 years. Individuals were selected through convenience sampling. The life satisfaction questionnaire by Diener, Basadur Creative Problem-Solving and Hopefulness questionnaires were used to collect data. 
Findings: Intergroup comparison showed that the difference between the mean scores of life satisfaction (p=0.042), problem-solving skills (p=0.049), and hope (p=0.012) between the experimental and control groups was significant. Therefore, administering group Impact Therapy was effective and increased life satisfaction, problem-solving skills and hope of adolescent girls in stressful families. 
Results: Impact Therapy helped participating teenagers cope with and overcome their stress by promoting resilience. Teenagers from tension-filled families became more determined individuals and gained more control over the events surrounding them. In other words, these interventions helped people to better deal with various issues in life and even consider unpleasant events as opportunities.
The effect of biochar from rice husks on evapotranspiration, vegetative growth and fruit yield of greenhouse tomato cultivar anna F1 grown in two soil types
Authors:   Meru University of Science and Technology, Masinde PW , Wahome BM
Published: July 2022

Biochar made from crop residues has been shown to improve soil texture, soil porosity and soil structure. It can enhance fertilizer utilization, reduce leaching loses and hence improve nitrogen supply for plant growth. Utilization of biochar in preparation of potting substrates can enhance growth and yields of greenhouse tomato. A study was carried out to test the influence of rice husks biochar on substrate properties, growth and yield of greenhouse tomato. The experiment was carried as a factorial in completely randomized design with two factors: four biochar levels and two soil types, replicated three times. The biochar levels were volume ratios of 0 biochar: 1 soil (0Biochar), 0.25 biochar: 0.75 soil (0.25Biochar), 0.5 biochar: 0.5 soil (0.5Biochar) and 0.75 biochar: 0.25 soil (0.75Biochar). The two soil types used were the well drained deep red friable soil and imperfectly drained dark brown clay soil obtained from the University farm. Tomato Anna F1 was grown in four-liter plastic pots containing about 3 kg of soil-biochar mixture. Data were collected on the plant growth parameters of plant height, number of leaves per plant and plant dry weight upto the 8th - 9th week after transplanting, when fruit ripening began. The chlorophyll index of the leaves were measured using the SPAD meter. At harvesting, fresh weight and number of the fruits were determined. Incorporating biochar into potting substrate at 0.25-0.75 levels significantly increased evapotranspiration during early vegetative growth. This was indicative of biochar changing substrate properties mainly through significant reduction of bulk density and possibly increasing porosity. Biochar levels of 0.25-0.75 resulted in significant increases in vegetative growth and fruit yield of tomato. Adding biochar to the pot substrate increased tomato plant height, plant dry weight and fruit fresh weight by 21-34%, 50-64% and 49%-56%, respectively. The increase in vegetative growth and fruit yield at 0.25-0.75 biochar levels was attributed to the positive effect of biochar on substrate physical properties. Plant height and number of leaves per plant had a significant linear relationship whose slope, the rate of increase in plant height with increase in number of leaves was not influenced by biochar levels. Biochar enhanced growth without changing the ratio of plant height to number of leaves of tomato. It is concluded that incorporation of biochar made from rice husks at 0.25 level can enhance greenhouse production in both red and clay soils. Key words: Bulk density, Dry weight, Fresh fruit weight, Number of leaves, Plant height

Published: July 2022

The study was carried out at the Livestock Teaching and Research Farm of Federal University Dutsin-Ma to monitor the performance of Sokoto red bucks fed urea treated and untreated rice milling waste. Twenty entire male Sokoto red bucks were used. The experimental animals were allotted (n=5) in a completely randomized design (CRD) to diets A and B with 15% and 30% inclusion levels of untreated rice milling waste, respectively, while C and D contained 15% and 30% inclusion levels of urea treated rice milling waste, respectively, in a completely randomized design (CRD). The feeding trial lasted for 84 days while the digestibility trial lasted for 14 days. Three randomly selected experimental bucks from each experimental treatment were housed in the metabolic cages and their faeces collected for seven days using faecal bag after the seven days adaptation period. The faeces were weighed and bulked 10% collected and oven-dried before they were stored in polythene bags until required for analysis. Urine was also collected for seven days inside the metabolic cages using urinary funnel piped into the bottle containing 2 ml 10% sulphuric acid to trap the nitrogen content. 10% of the urine was sampled and stored in freezer at -2C for chemical analysis. The dry matter intake was significantly higher (P<0.05) in treatments A and B than other treatments. However, this did not result in significantly better (P<0.05) performance (feed efficiency and Cost of feed/ live weight gain) as shown with treatment C and D that had significantly better (P<0.05) weight gain, feed efficiency, nutrients digestibility and nitrogen retention. The cost of feed per kg live weight was shown to be significantly lower (P<0.05) in treatments C and D compared to treatment B which was significantly lower (P<0.05) than treatment A. The study concluded that diet D which contained 30% inclusion level of urea treated rice milling waste was the best among all the diets because of the lowest cost per feed live weight of 1.40 USD/kg and feed efficiency of 0.10.

Assessment of the domestic energy use impacts of unplanned refugee settlements on the forest ecology of Cox’s Bazar, Bangladesh
Authors: Islam Tariqul , Hemstock Sarah L. , Charlesworth Mark , Kabir Kazi Humayun
Published: July 2022

This study monitors the forest ecology in Himchari National Park, Teknaf Wildlife Sanctuary, and between the areas in Cox's Bazar district, Bangladesh. The area has a rich biodiversity, including globally endangered species such as Asian Elephants (Elephas maximus) and Boilam Trees (Anisoptera scaphula), which are threatened by anthropogenic development, newly refugees’ unplanned settlements and their use of domestic energy. Geographic Information System (GIS) and Landsat satellite images are used to monitor forest coverage for 1995–2018. The Normalized Difference Vegetation Index (NDVI) is applied to quantify forest area. Focus group discussions and questionnaire surveys were conducted to reveal stakeholder perceptions about their dependency on forest resources as ecosystem services. Close to the refugee camp areas, the forest coverage changes to grassland due to the unsustainable forest resource extraction. Despite the free of charge supply of Liquefied Petroleum Gas, the refugees burn 2,380 metric tons of firewood every month to satisfy energy for cooking. Besides, 200,000 households frequently use bamboo, small trees, and shrubs to maintain their dwellings' structure. Thus, deforestation caused by immigration between 2017–2018 is similar to that caused by the effect of climate change, including severe tropical cyclones in 1994–1995. This research identifies domestic energy supply deficiency and impacts, and the need for comparatively durable housing materials to reduce stress on forest resources and health hazards.
Conciencia ecosocial
Authors: Lukomski Jurczynski Andrzej , Coronado Padilla Jorge Augusto
Published: July 2022

Existen dos formas opuestas de pensar la relación entre la naturaleza y el hombre. Una es la de dominio, donde el hombre quiere someter, totalmente, la naturaleza, a los intereses de su propia especie, tratándola como fuente de recursos. La segunda - opuesta a la anterior- es la relación de subordinación. Esta última es la relación que caracteriza a los grupos ecologistas y movimientos poíticos de los partidos verdes en el continente europeo y otros países del mundo.
En este sentido, el texto propone un equilibrio entre el desarrollo del hombre (desde su bienestar) y el desarrollo sostenible de la naturaleza donde no se puede perder de vista el mundo vivo no humano así como su bienestar y conservación.
Autobiografía lingüística: una aproximación a las elecciones de lengua de los lingüistas
Authors: Junquera Macarena
Published: July 2022

La problemática de la elección lingüística es uno de los principales objetos de análisis dentro de las ciencias del lenguaje, particularmente en el campo de la sociolingüística. Sin embargo, faltan estudios que aborden explícitamente las elecciones de lengua que hacen los propios lingüistas e indaguen de manera sistemática acerca de sus reflexiones metalingüísticas sobre sus propias preferencias yrechazos. En este sentido, el presente artículo tiene como objetivo exponer los aportes desarrollados acerca del concepto de autobiografía lingüística, noción que, en nuestro trabajo, remite a un texto de carácter autorreferencial, en el que el lingüista –su autor– reflexiona sobre las elecciones de lengua que ha tenido que realizar en el marco de su profesión u otra esfera de su vida, así como en los motivos en los que estas se sustentan.
“It’s not just about improving my Spanish.” Student Perceptions of Service Learning
Authors: Ali Farah
Published: July 2022

In the last few decades, service learning (SL) has emerged as an instructional model that facilitates connections between learning experiences in and outside the classroom, and highlights the socio-political nature of language use (Grim, 2010; Bettencourt, 2015; Moreno-López et. al, 2017). However, its effective and relevant curricular implementation remains a challenge for educators. This exploratory paper examines how SL impacts advanced learners’ beliefs, attitudes, and motivation towards learning Spanish, as well as their ability to connect their service experiences with course content. Findings show that learners evaluate service experiences through a proficiency-based lens, where the success of their experiences depended on the amount of Spanish used and perceived improvements in proficiency. Additionally, while participants were frequently able to connect their SL experiences with course content, they did not necessarily recognize those learning moments as beneficial.
Considerazioni chiave: equità e partecipazione nella promozione della vaccinazione per il covid-19 tra le persone razzializzate e senza documenti
Authors: Vallerani Sara , Storer Elizabeth , Torre Costanza
Published: July 2022

Questo documento espone alcune considerazioni a proposito della promozione dei vaccini per il SARS-CoV-2 e delle strategie per garantirne un’equa distribuzione tra gli immigrati senza documenti residenti in Italia e, in particolare, a Roma. Quanto emerge dal caso italiano può essere in parte applicabile ad altri contesti in cui la somministrazione del vaccino è stata legata al dispositivo del “passaporto vaccinale”, ovvero il certificato COVID digitale dell'UE, in Italia Green Pass. Nell’organizzazione della campagna vaccinale alcune categorie sociali sono state identificate come “difficili da raggiungere” (hard to reach) e per cui è necessario immaginare interventi specifici.1 In questo testo si sceglie di parlare di persone razzializzate e illegalizzate poiché senza documenti per riferirsi a persone immigrate che non hanno cittadinanza, permesso di soggiorno e status di rifugiato. Questo documento esplora il contesto quotidiano delle vite delle persone illegalizzate e come l’esperienza della pandemia di COVID-19 abbia esacerbato le difficoltà che queste persone incontrano, 23 mettendo in luce il collegamento tra le vulnerabilità, consolidate ed emergenti, con la percezione dei vaccini. Si suggerisce come l’orientamento e la percezione dei vaccini si inseriscano all’interno dei contesti di vita delle persone, in cui molto spesso la priorità è data al sostentamento economico. In molti casi, l’accettazione della vaccinazione è motivata dalla necessità di continuare ad avere un lavoro retribuito piuttosto che a una preoccupazione connessa alla salute o a una fiducia nei confronti delle istituzioni sanitarie. Il seguente documento si pone l’obiettivo di esaminare come i vaccini possano essere distribuiti in modo equo e capace di aumentare la fiducia e i processi di inclusione nella società post-pandemica. Il testo si basa principalmente sulla ricerca etnografica e le testimonianze raccolte attraverso interviste e osservazioni con persone razzializzate e illegalizzate nella città di Roma, insieme a rappresentanti della società civile e operatori socio-sanitari tra dicembre 2021 e gennaio 2022.

Renewable energy has been highlighted not only as a means of satisfying the energy needs of Nigerians but also as a tool for the country's growth, thereby improving the income of the citizens who have more energy to work with, serving as the energy source for domestic and office use, in addition to reducing the carbon footprint from the conventional fossil fuels. From data obtained from the Photovoltaic Geographic Information System (PVGIS), the solar electricity potential at some selected cities in Southern Nigeria that ranges from 4.5 to 6.5 kWh/m2 has been presented as a tool, which when properly harnessed, can be used to mitigate avoidable energy-related “national disasters” such as unemployment and youth-restiveness, thereby accelerating Nigeria’s development. There is the urgent need to revise and effectively implement helpful laws and policies that support the addition of renewable energy sources for electricity generation. Lack of a coherent legal framework with incentives for the utilization of renewable energy is among the key factors causing poor utilization of renewable energy in Nigeria. Governmental and stakeholder collaboration is highly necessary for developing countries to robustly track renewable electricity adoption via laws aimed at boosting its adoption.
Nerve decompression in diabetics with chronic nerve compression: update 2022
Authors: Dellon Arnold Lee
Published: July 2022

The number of people with diabetes worldwide has reached epidemic proportions. Diabetics are well-known to have chronic nerve compressions, and the prevalence of compressions exceeds 50% in those with neuropathy. The loss of sensation in the feet of people with diabetic neuropathy is the primary cause of their ulceration and amputation, as well as pain. The aim of this article is to update the reader on the current status of lower extremity nerve decompression in patients with diabetic neuropathy. A review of the history and literature related to the current approach to the patient with chronic nerve compression plus diabetic neuropathy was undertaken. The current evidence is overwhelmingly clear, in diabetics with neuropathy and a positive Tinel sign over the tibial nerve at the tarsal tunnel, that decompression, by neurolysis of lower extremity nerves, can relieve pain, restore sensation, and prevent ulceration and amputation. Furthermore, economic cost-benefit analysis by the Markov technique demonstrates that lower extremity nerve compression is not only cost-effective compared to standard medical care, but also increases the quality of life and life expectancy. The remaining barriers to acceptance and implementation of this proven surgical approach must lie in the education of physicians in training and re-education of diabetes educators, primary care providers and endocrinologists.
Clinical application of autologous chyle fat transplantation in the correction of sunken upper eyelid
Authors: Qi Lin , Wang Pu , Chen Xingfan
Published: July 2022

Aim: We investigated the clinical application of autologous chyle fat in the correction of sunken upper eyelid. Methods: From November 2020 to October 2021, 89 cases of correction with autologous chyle fat to sunken upper eyelid were performed (with or without other cosmetic procedures related to the eyes). An appropriate amount of fat was extracted from the superficial layer of the patient’s thigh and processed to chyle fat. About 0.5-2.8 mL of fat was injected under the orbicularis oculi muscle (roof-retro orbicularis oculi fat) or in the area where the orbital septal fat exists from the outer orbital margin of the upper eyelid. Results: In total, 59 patients were followed up for 1-11 months after surgery. No infection, necrosis, vascular embolism, upper eyelid lumpiness, fat calcification, or liquefaction occurred in all patients, while seven cases showed inadequate correction. The depression basically disappeared, the shape was relatively full, the youthfulness was greatly improved, and the satisfaction of patients was high during the follow-up period. Conclusion: The correction with autologous chyle fat to sunken upper eyelid showed little trauma, short recovery periods, and satisfactory results, and it is worthy of being popularized and applied more widely.

Це свідчить про потребу саме в такому типі взаємодії. Основна задача роботи – це вдосконалення взаємодії з союзними роботами, що мають інші кодові бази. Такі роботи не мають змоги комунікувати – тільки аналізувати дії союзних гравців і бути корисними для досягнення спільної мети. Також присутній елемент внутрішньо-командної конкуренції, коли задача агенту не тільки максимально допомогти союзним роботам, а і стати найрезультативнішим гравцем в команді. Тема основної роботи охоплює проблематику окремих випадків тактики гри команди, на кшталт, гри з застосуванням тільки нападаючих моделей поведінки, гри з застосуванням тільки оборонних моделей, різних комбінацій моделей поведінки для визначення глобального оптимуму виграшної тактики. За результатами тестування було визначено ефективність розроблених моделей поведінки, найкращі співвідношення застосувань моделей на полі, а також протестовані пограничні випадки застосування моделей, що підтвердило теоретичні передбачення.

In recent years, the radio communication system has undergone significant modernization. This concerns both the design and development of new means of communication and the improvement and modernization of existing ones and the development of new antenna-feeder devices for them. A general feature of radio communication networks is the significant dependence of the main characteristics of communication objects on the type and parameters of antenna systems and on decisions regarding their location. The developed technique of constructive synthesis of the antenna system of the radio communication device built on low-lying emitters is offered, with the help of which it is possible to synthesize the antenna system which will improve the technical characteristics of the mobile radio communication means. The method of constructive synthesis of the antenna system of radio communication equipment built on low-lying emitters is based on the mathematical model of calculating the directional characteristics of the speaker from low-located emitters for radio communication facilities. This model was presented in the article “Mathematical model for calculating the directional characteristics of the system of vibrators of radio communication equipment” [1]. Research methods – synthesis of antenna systems with the necessary pattern is based on the Hertz vector method, the method of induced electromotive forces, the method of mirror images and analysis of the results. The influence of the shape and number of elements of the antenna system on the formation of its radiation pattern is determined and the calculation for the selection of the optimal design with the required electrical characteristics is established. That is, the proposed technique helps to improve and simplify the technical performance of transmitting and receiving speakers. Based on the results of the research, a mathematical model for calculating the directional characteristics of the AS, built on low-lying emitters for radio communication equipment and methods of constructive synthesis of AS radio communication equipment built on low-located emitters, which is possible in the absence of with realized gain up to 16 dB. It is expedient to apply the developed technique: during the development of new AS and antenna-feeder devices for modern field radio communication equipment and AS for unmanned aerial vehicles; during the organization of communication by a field special radio communication node.

Aim. To investigate the relationship between the expression of Ca2+ handling proteins of the sarcoplasmic reticulum, polymorphic variants of their genes, and structural and functional parameters of the heart in patients with atrial fibrillation (AF).

Materials and methods. The study included patients with AF. The patients underwent radiofrequency ablation, during which a myocardial biopsy was taken. The patients underwent echocardiography (EchoCG) before surgery. Polymorphic variants rs1860561 of the ATP2A2 gene and rs6684209 and rs7521023 of the CASQ2 gene were determined in the patients by real-time polymerase chain reaction (PCR), and the level of expression of SERCA2a and CASQ2 proteins in the myocardium was detected by immunoblotting.

Results. Carriers of the GG genotype at rs1860561 of the ATP2A2 gene and CC genotype at rs6684209 of the CASQ2 gene were characterized by significantly higher expression of the corresponding proteins. Using cluster analysis, we identified groups of patients by the level of SERCA2a and CASQ2 expression: group 1 – patients with low protein content; group 2 – patients with high protein content. According to clinical and anamnestic parameters, the patients in the selected groups were homogeneous. In patients with high SERCA2a levels, the end systolic and diastolic volumes of the left ventricle (LV) were significantly higher than those in patients with low levels of this protein. The rates of early (peak E) and late left ventricular diastolic filling (peak A) were significantly lower in the group with high SERCA2a expression. A comparative analysis of EchoCG data of patients distributed by the level of CASQ2 expression in the myocardium did not reveal significant differences between the groups.

Conclusion. The polymorphic variant rs1860561 of the ATP2A2 gene and rs6684209 of the CASQ2 gene can modulate the level of SERCA2a and CASQ2 expression. SERCA2a expression is associated with the functional and structural parameters of the heart in patients with AF.

Acellular dermal matrices (ADMs) are gaining popularity as surgical materials for operations on the pelvic organs, as well as in burn therapy and plastic surgery. Evaluation of the biocompatibility of surgical materials is an important and necessary step in the development of new ADMs.

The aim of the study was to compare the results of subcutaneous implantation of ADM and native porcine skin in rats.

Materials and methods. To obtain ADMs, detergent – enzymatic decellularization was used. On days 7, 14, 21, and 60 after the implantation of ADMs (the experimental group) and native porcine skin (the control group), the animals were removed from the experiment. The histologic sections were stained with hematoxylin – eosin and Masson’s trichrome stain, then an immunohistochemical reaction with antibodies to CD3 and CD68 was performed. Computer morphometry was carried out using the ImageJ software.

Results. On day 7 after the implantation, moderate sterile inflammation in the experimental group and pronounced sterile inflammation with eosinophil infiltration in the control group were observed. On day 14 of the experiment, the samples from the experimental group were characterized by a relatively low content of macrophages and T-lymphocytes with insignificant edema and no signs of ADM biodegradation. The control group showed pronounced inflammation, a large number of infiltrating macrophages and T lymphocytes, as well as fragmentation of collagen fibers. On day 21 of the experiment, a thin capsule was formed around ADM, there was a small number of infiltrating T lymphocytes and macrophages, the collagen fibers of the implant were intact. In the samples of the control group, there was pronounced inflammation with the presence of a significant number of lymphocytes and macrophages, as well as fragmentation and vascularization of the implant. On day 60 of the experiment, no inflammatory response was observed around ADM, biodegradation was minimal, and a dense fibrous capsule was formed around the fragment of the native porcine skin.

Conclusion. The experimental ADM has low immunogenicity and a low degree of biodegradation, which makes it possible to use it for further research to create efficient surgical material that is safe for use in clinical practice.

Gene electrotransfer is one of the main non-viral methods for intracellular delivery of plasmid DNA, wherein pulsed electric fields are used to transiently permeabilize the cell membrane allowing enhanced transmembrane transport. By localizing the electric field over small portions of the cell membrane using nanostructured substrates, it is possible to increase considerably the gene electrotransfer efficiency while preserving cell viability. In this study, we design an electrotransfer approach based on commercially available cell culture inserts with polyethylene-terephthalate (PET) porous substrate. We first use multiscale numerical modelling to determine the pulse parameters, substrate pore size, and other factors that are expected to result in successful gene electrotransfer. Based on numerical results we design a simple device combining an insert with substrates containing pores with 0.4 um and 1.0 um diameter, a multiwell plate, and a pair of wire electrodes. We test the device in three mammalian cell lines and obtain transfection efficiencies similar to those achieved with bulk electroporation, but with low-voltage pulses that do not require the use of expensive electroporators. Our combined theoretical and experimental analysis calls for further systematic studies that will investigate the influence of substrate pore size and porosity on gene electrotransfer efficiency and cell viability.
