Authors: Akram A , Arshad K , Hafeez MN
Published: September 2021

Different types of abiotic stresses inhibit the normal growth of plants by changing their physical biochemical, morphological, and molecular traits. It links to the polygenic traits, which is controlled with the help of different genes, due to this polygenetic the manipulation of foreign genetic makeup is very difficult. Drought stress is the very major type of threat to reduce the yield of cash crops in Pakistan and as well as in all over the world. Gene manipulation is the solution to face this problem by producing genetically modified crop plants that have the ability to survive in drought conditions. Universal stress protein gene has been already identified in bacteria which showed its response under stressed conditions, by manipulation of universal stress protein gene. It was found from our study that the bacterial cells transformed with the USP2 gene isolated from cotton induced abiotic stress tolerance under heat, osmotic, and salt stress. It was suggested from our findings that the USP2 gene could be used to produce abiotic stress tolerance transgenic crop plants to enhance crop plant yield and quality.

Published: September 2021

Background:In this study, we aimed to share our singlecenter experience and to investigate the effect of interventional bronchoscopic procedures on secondary pulmonary malignancies in terms of complications, success, and survival rates.

Methods:A total of 83 patients (42 males, 41 females; mean age: 57.8±15.2 years; range, 18 to 94 years) with secondary pulmonary malignancies who underwent interventional bronchoscopic procedures between January 2009 and December 2019 were retrospectively reviewed. Data including demographic and clinical characteristics of the patients, complications, and success and survival rates were recorded.

Results:The most common secondary pulmonary malignancies were kidney and thyroid tumors with the complaints of cough, shortness of breath, and hemoptysis. The mean duration before the diagnosis was 34.7±52.8 (range, 0.1 to 219.3) months, and the mean survival after the diagnosis were 10±13.1 (range, 0.2 to 44.4) months. A total of 92% of the patients had an airway obstruction of >50% and the interventional bronchoscopic procedures such as argon plasma coagulation, laser, cryo, and mechanical resection were successful in achieving airway patency. Laser application was found to significantly improve survival (p=0.015). Acute complication rate was 8.4% and mortality rate was 0%.

Conclusion:In patients with tracheobronchial lesions due to secondary pulmonary malignancies, interventional bronchoscopic procedures, regardless of the stage of the disease, provide rapid palliation in life-threatening symptoms such as dyspnea and hemoptysis due to airway obstruction, prolonging patient"s survival and gain time for additional treatments to take effect for primary disease.
Donor selection for lung transplant in Turkey: Is it necessary to wait for an ideal donor?
Authors: Vayvada Mustafa , Erdal Taşçı Ahmet
Published: September 2021

Background: The aim of this study was to evaluate the donor criteria used in lung transplantation in our clinic.

Methods: A total of 55 cadaveric donors who were accepted for lung transplantation in our clinic between December 2016 and January 2019 were retrospectively analyzed according to ideal donor criteria. The donors were divided into two groups as ideal and non-ideal ones according to their age, partial pressure of oxygen in arterial blood, history of smoking, and ventilation day. Donor data, recipient characteristics and survival outcomes were evaluated.

Results: Of 55 donors accepted for lung transplantation, 24 (43.7%) were ideal and 31 (56.3%) were non-ideal donors. The 90-day mortality and one-year survival rates were not significantly different between the two groups. The 90-day mortality was 25% in the ideal group and 22.6% in the non-ideal group (p=0.834). The one-year survival rates after lung transplantation were 64.5% versus 70.6% in the ideal and non-ideal groups, respectively (p=0.444).

Conclusion: The whole clinical picture should be evaluated before accepting or rejecting donors for lung transplantation. The use of lung donors that do not meet the ideal criteria does not impair short- and mid-term results, compared to ideal lung donors. Strict implementation of donor criteria may prevent using suitable donors for lung transplantation. Use of non-ideal donors can reduce waiting list mortality.

Published: September 2021

Background:This study aims to investigate the role of telomerase activity in the risk of primary spontaneous pneumothorax, which is most frequently encountered in the practice of thoracic surgery.

Methods:A total of 61 patients (56 males, 5 females; median age: 29.4 years; range, 17 to 43 years) who underwent treatment for primary spontaneous pneumothorax and 19 age- and sex-matched healthy controls (10 males, 9 females; median age: 29.1 years; range, 23 to 43 years) were included in this prospective study between January 2018 - August 2018. Telomerase activity was evaluated with enzyme-linked immunosorbent assay. The correlation between telomerase activity and clinical and demographic parameters was examined.

Results:The mean serum telomerase level was 3.4±0.6 ng/mL in the primary spontaneous pneumothorax group and 1.9±0.5 ng/mL in the control group, indicating significantly higher levels in the patient group (p<0.001). There was no significant association between the telomerase levels and presence of blebs and/or bullae on thoracic computed tomography, extent of pneumothorax, laterality (right, left, or bilateral), and pack years of cigarette smoking.

Conclusion:Telomerase levels of patients with primary spontaneous pneumothorax are significantly higher than healthy individuals. Future genetic studies may ultimately clarify a potential relationship between primary spontaneous pneumothorax and short telomere syndrome.

Published: September 2021

Redo-cardiac surgery is associated with high morbidity and mortality rates. Although redo surgery are relative contraindications for robotic surgery, robotic redo mitral valve surgery has been performed with endo-aortic occlusion techniques and on fibrillated heart successfully. Beating heart mitral valve surgery is another well-known option for redo cardiac surgery practice. Robotic beating heart surgery is not well-studied before. As a new point of view to robotic reoperation surgery, herein, we aimed to present a case who underwent redo robotic mitral valve replacement combined with dysfunctioned amplatzer plug resection on a beating heart.

Published: September 2021

Background: This study aims to investigate the effects of 2-aminoethoxydiphenyl borate (2-APB) on aortic clamping-induced lung and kidney tissue oxidation, tissue inflammation, and histological damage in a rat model.

Methods: A total of 28 adult female Wistar albino rats were randomly allocated to four equal groups: Control group, ischemia-reperfusion group, dimethyl sulfoxide group, and 2-APB group. Animals in the control group underwent median laparotomy. In the remaining groups, supra-celiac aorta was clamped for 45 min and, then, reperfusion was constituted for 60 min. The 2-APB (2 mg/kg) was administered before clamping. The remaining groups received saline (ischemia-reperfusion group) or dimethyl sulfoxide (dimethyl sulfoxide group). Kidney and lung tissue samples were harvested at the end of reperfusion.

Results: Aortic occlusion caused increased tissue total oxidant status and reduced total antioxidant status and glutathione levels in the ischemia-reperfusion and dimethyl sulfoxide groups. Tissue interleukin-1 beta and tumor necrosis factor-alpha levels, nuclear factor kappa beta activation, and histological damage severity scores were also higher in these groups. The 2-APB treatment eliminated the increase in total oxidant status and the decrease in total antioxidant status and glutathione levels. It also caused a decrease in the interleukin-1 beta levels, although it did not significantly alter the tumor necrosis factor-alpha levels, nuclear factor kappa beta immunoreactivity, and histological damage scores.

Conclusion: Borate exerted a beneficial antioxidant effect as evidenced by reduced oxidative stress; however, it did not inhibit nuclear factor kappa beta activation and prevent histological damage in supra-celiac aortic clamping-induced kidney and lung injury in rats.
Historiografija o Tuzli i Tuzlanskom kraju,1 koja se odnosi na novi vijek i savremeno doba, nastala u vremenu 2001–2018. godine
Authors: Šabotić Izet
Published: September 2021

U radu su date osnovne karakteristike razvoja historiografije o Tuzli i Tuzlanskom kraju u periodu od 2000. godine do danas, vezanom za novi vijek i savremeno doba. Ukazano je na to da je u navedenom vremenu značajno pojačan interes i intenziviran istraživački rad na proučavanju prošlosti Tuzle i Tuzlanskog kraja. Tome su u znatnoj mjeri doprinijele određene okolnosti. Jedna od njih jeste nedovoljna istraženost ovog perioda tuzlanske prošlosti, što je motiviralo i podstaklo istraživače da se značajnije bave njome. Značajan podsticaj istraživanju ove problematike dao je Odsjek za historiju Filozofskog fakulteta u Tuzli, kao i brojni časopisi koji su nastali u ovom vremenu, a usmjereni su na istraživanje mikrohistorije. To je doprinijelo tome da nastanu brojni historiografski sadržaji: sinteze, monografije, studije te veliki broj članaka i priloga koji tretiraju prošlost Tuzle i Tuzlanskog kraja. U radu su historiografski sadržaji tretirani i predstavljeni po periodima (osmanski, austrougarski, period 1918–1941, Drugi svjetski rat, socijalistički period 1945–1990. te period 1992–1995) te vrsti sadržaja (sinteza, monografija, studija, članak, prilog, doktorska i magistarska radnja i slično), a sve kako bi se dobila što preglednija slika ukupnih historijskih sadržaja vezanih za Tuzlu i Tuzlanski kraj u navedenom vremenu. U tom smislu iskazan je interes za pitanja ove provenijencije, što je rezultiralo značajnim brojem raznovrsnih radova. Što je dobro! Ono što je manje dobro odnosi se na nesistematičnost, koja je dovela do naučne i stručne neujednačenosti radova. Jedan broj radova je zasnovan na metodološkim i naučnim načelima i principima historijske nauke, što predstavlja značajan doprinos, dok ih jedan broj ima dominantno publicističke, politološke, sociološke i druge karakteristike. Međutim, mišljenja smo da je u navedenom periodu učinjen važan iskorak na planu bolje istraženosti Tuzle i Tuzlanskog kraja, što predstavlja značajan doprinos ukupnom razvoju bosanskohercegovačke historiografije.
Bosna i Hercegovina u udžbenicima historije u Republici Sjevernoj Makedoniji
Authors: Ramčilović Zećir
Published: September 2021

Uloga znanja i obrazovanja je primarna za razvoj svih segmenata savremenog društva. Sve naučne discipline imaju svoj značaj, svoje postavljene ciljeve u izgradnji kvalitetnog ljudskog potencijala. U ovom pravcu historija je u odgojno-obrazovnom procesu jako značajna, posebno u multietničkim društvima. Historija kao nastavni predmet kroz sticanje znanja o prošlosti stvara predstavu o svakom pojedincu, predstavu o sebi i predstavu o drugim. Zbog toga se često stavlja u funkciju podizanja nacionalne svijesti, patriotizma te homogenosti države, što je najčešće dovodilo do stvaranja predrasuda, podjela i diskriminacije naroda u državama regiona. Države nastale na ruševinama jugoslavenskog ideološkog sistema ne samo da imaju potrebu već moraju raditi na jačanju razumijevanja i povjerenja među narodima, posebno kroz nastavu koja će imati za cilj uklanjanje predrasuda i naglašavanje pozitivnog međusobnog uticaja različitih naroda i država. Republika Sjeverna Makedonija pravi napore da rastereti nastavne sadržaje koji stvaraju podjele i predrasude. Udžbenici trebaju odražavati postavljene ciljeve nastavnih programa, kao i metodologiju pisanja udžbenika. Nastavni programi predviđaju izučavanje historije makedonskog naroda, ali i historije ustavotvornih naroda i država njihovog porijekla srazmjerno njihovom procentualnom učešću u ukupnom stanovništvu. Bošnjaci su ustavotvorni narod RS Makedonije, a njihova matica država je Bosna i Hercegovina. Ovim radom želimo analizirati koliko su sadržaji o Bosni i Hercegovini i Bošnjacima zastupljeni u udžbenicima te koliko su ispravni. Ne samo zbog značaja Bošnjaka za izgradnju i razvoj makedonske države i društva već i zbog mnogih zajedničkih viševjekovnih historijskih procesa, zajedničkih država čiji su dio bili od XV do kraja XX vijeka. Jako je važno da sadržaji o Bosni i Hercegovini i Bošnjacima budu zastupljeni i pravilno predstavljeni mladoj populaciji. Ukoliko obrazovanje ispuni svoju misiju koja predstavlja ključni faktor za međusobno razumijevanje u multietničkom i multireligioznom makedonskom društvu, možemo očekivati i njegov dugoročni socijalni i ekonomski razvoj. Ovim istraživanjem želimo utvrditi faktičko stanje ovog aspekta udžbenika Historije iza kojih stoje institucije koje se brinu za razvoj kompetentnog, kreativnog, građanski orijentiranog i etički izgrađenog ljudskog kapitala.

Authors: Cerqueira Eugênia Dória Viana
Published: September 2021

Nas últimas duas décadas, enfatiza-se que as periferias metropolitanas têm testemunhado uma inflexão do processo tradicional de expansão urbana, com o surgimento de estruturas policêntricas e multifuncionais, que suscitam uma reestruturação das práticas de mobilidade. Este artigo tem como objetivo compreender as desigualdades de mobilidade nas periferias da Região Metropolitana de Belo Horizonte (Brasil), em um contexto de diversificação socioespacial dos espaços em questão. Expõe-se os principais resultados de uma série de entrevistas semiestruturadas, que apontam para uma articulação entre novas práticas de mobilidade, moldadas pela emergência de estruturas pós-suburbanas, e intensas desigualdades, decorrentes do modelo de urbanização centro-periferia.
Study on Real-Time Porosity Defect Detection Through Neural Network Structure Optimization using Genetic Algorithm in GMAW
Authors: Lee Dongwook , Jin Chengnan , Rhee Sehun
Published: September 2021

Zinc-coated steel sheets are widely applied as automotive chassis parts because they have high corrosion resistance and good compatibility. However, in the gas metal arc welding (GMAW) process, serious porosity defects occur due to zinc vapor generated during welding, which causes problems such as durability or productivity reduction in the welded structure. To secure weldability and productivity, it is essential to secure monitoring technology that determines whether porosity defects are generated in real-time. To solve this problem, this study provides a method of extracting feature variables from arc voltage signals generated during welding and optimizing the hyper parameters of the porosity detection algorithm deep neural network (DNN) which be learned with feature variables by applying genetic algorithm (GA). To verify the performance of the proposed method, as a result of applying it to the optimized DNN model using the experimental data of the GMAW experiment using a high-strength zinc-coated steel sheet, a prediction accuracy of 93.1 % was derived, which is improved by 3.60 % than DNN model from previous research.
EARTH AS PRIMORDIALLY HYDROGEN-RICH PLANET: HYPOTHESIS AND REALITY
Authors: Pospeev А. V.
Published: September 2021

The article is focused on the role of natural hydrogen in the Earth geodynamics and energy potential. With a proper consideration of the physical parameters of the Earth’s core and mantle, we discuss the aspects of the Hydridic Earth (or Primordially Hydrogen-Rich Planet) theory, which is currently used as a fundamental hypothesis in modern projects aimed at hydrogen energetics.

A probability of finding natural hydrogen deposits in sedimentary traps is estimated. It is shown that the volume of deep degassing of hydrogen can be calculated from various cosmological, petrophysical and geochemical data, and an average volume is two orders of magnitude less than the amount predicted by the Hydridic Earth hypothesis. This hypothesis gives grounds to conclude that the major part of Earth’s mantle is a metal sphere; however, this conclusion is not supported by the geological and geophysical data.

Este artigo tem por objetivo apresentar alguns dos desafios na organização de currículos da escolarização de pessoas jovens e adultas, de modo a se cumprir as metas educacionais postuladas para essa modalidade de ensino e efetivar o direito à educação para todos os cidadãos. Interessa investigar, por meio de análise documental, como um conjunto de princípios norteadores que emergiram do campo da educação popular e que indicam um certo acúmulo de conhecimentos para a produção de currículos na área pode ser observado, tomando como referência empírica as bases de um currículo voltado à educação de jovens e adultos (EJA). Igualmente, pretende-se verificar como se apresentam, no documento, as relações entre conhecimentos do cotidiano e os conhecimentos científicos. Os resultados obtidos por esta análise mostram que há uma apropriação das principais categorias do campo da EJA para pensar o novo currículo, mas é possível perceber que a relação entre conhecimentos cotidianos e científicos precisa ainda ser trabalhada de forma mais rigorosa, considerando a função social da escola.

Não basta ser mulher... não basta gostar de crianças... “Cuidado/educação” como princípio indissociável na Educação Infantil
Authors: Sayão Déborah Thomé
Published: September 2021

Resumo O presente artigo é parte da tese de doutorado em cujo foco estava o trabalho docente de professores na Educação Infantil. Na tese, era objetivo compreender como os homens se constituem como docentes na educação das crianças de zero a seis anos – profissão caracterizada como “tipicamente feminina”. Assinalando a opção por uma perspectiva socioantropológica e a partir dessa perspectiva, é explicada e conceituada a categoria central do estudo – relações de gênero, entendendo as mesmas como uma construção social pelas quais é possível compreender como hierarquia, diferença e poder se moldam, conformam, instalam e atuam nas identidades e nos espaços institucionais. O texto aqui apresentado destaca o conceito de cuidado/educação considerado como princípio indissociável na Educação Infantil, partindo do pressuposto de que o corpo está no cerne do debate acerca dos cuidados na infância menor. A partir dos dados empíricos encontrados, tornou-se necessário problematizar o debate empreendido na área da Educação Infantil acerca das concepções e das práticas que o binômio cuidado/educação das crianças pequenas vem assumindo, tomando o trabalho realizado por professores homens no interior das creches e centros de Educação Infantil no município de Florianópolis/Santa Catarina. A preocupação central aqui destacada denota como o cuidado era concebido quando professores atuavam em creches, pensando nos significados da educação das crianças pequenas, e deslindando conceitos e discursos sobre o “cuidado”. Para compreendê-lo, foi necessário investigar em que medida “cuidado”, como prática sociocultural e, no caso desse estudo, desenvolvida por homens e mulheres em creches, possibilitava avançar em relação às ambigüidades presentes nas expressões cuidado-e-educação, cuidado-educação ou cuidado/educação, grafias que vêm sendo usadas por diversos autores e autoras com significados semelhantes. Palavras-chave: Educação Infantil. Cuidado-educação. Relações de gênero. Trabalho docente. Prática sociocultural.

Até quando? Bullying na escola que prega a inclusão social
Authors: Tognetta Luciene Regina Paulino , Vinha Telma Pileggi
Published: September 2021

Não há quem não conheça casos de constrangimentos a que escolares são submetidos continuamente por seus colegas. Infelizmente o fenômeno bullying, termo inglês que significa intimidação, encontra-se mais disseminado do que se supõe. Numa investigação com 400 alunos de escolas públicas e particulares brasileiras, é comprovada a ocorrência de atos de violência física ou psicológica, intencionais e repetitivos, entre tais alunos. O estudo foi motivado pelas angustias e preocupações de escolas que sozinhas não têm conseguido resolver problemas de violência que se manifestam no seu interior. Quando entrevistadas com finalidades diagnósticas da situação que vivem, crianças e adolescentes apontam para o bullying como um problema sério que as atinge. No entanto, os dados mais significativos encontrados por essa investigação dizem respeito a uma questão que, propositalmente, fora inserida no questionário sobre bullying (baseado nos experimentos de Dan Olweus): crianças e adolescentes são menosprezados, humilhados ou zombados pelos próprios professores. Tal afirmação nos permite concluir que há ainda na escola uma lacuna quanto às formas pelas quais educadores de diferentes níveis escolares intervêm nos conflitos cotidianos, assim como pensam a formação moral de seus alunos. Palavras-chave: Bullying; Relação professor-aluno; Escola.
Gardening-based learning

Published: September 2021

The paper provides a theoretical overview of studies conducted within the framework of gardening-based learning. In nature, children can acquire a variety of skills and develop their environmental awareness in a space that represents a world of living examples. People are distancing from the nature, despite the fact that it can be a stimulating learning environment. It is necessary to return to the nature and design activities and programs where students will directly learn in the real world. The paper reviews the studies related to gardening-based learning within five domains: ecological, psychosocial, perceptual, the domain of school achievement and nutrition-health. Many researchers have created and implemented school garden programs and projects through which various positive effects have been achieved on cognitive, psychosocial, moral and physical development of children. Gardening-based learning programs result in increased awareness of proper nutrition and environment, higher learning outcomes and increase students' life skills. Experience gained in the garden encourages environmental literacy and management skills, improves awareness of the connection between plants and our clothes, food, lifestyle and sense of well-being.

Published: September 2021

Efficient transmission of energy from arbitrary types of primary sources and/or energy converters towaward appropriate control units and/or consumers can be a more or less complex process. In analogue to other existing branches of modern technology, energy transfer in agricultural machinery needs to be carried out very carefully, applying optimized technical solutions in each specified case. This factcts, (among many other problems) implies energy transmission that is technically, technologically, economically and environmentally aligned with the often difficult to predict dynamic needs of system components and the end user, with acceptable losses -at least in a wide range of possible environments defined by various possible conditions. This paper is the first upgrade of the series dedicated to the symbolic graphic representation of hydraulic system components according to valid technical standards. In this sense, the text presents and functionally describes only some of the much larger set of typical examples of hydraulic energy transmission and associated control functions in modern agricultural technology.

This research aimed at computing peak flow discharge using state-of-theart technology for watershed analysis to design a suitable open channel to minimize the effects of flood hazard during and after rainfall in an environment. A comprehensive topographical survey data obtained by Shuttle Radar Topographic Mission was employed in this study. The result of the survey shows that both the maximum and minimum elevation at 61.9 m and 51.1 m, respectively, and the mean slope of the area was 0.012. Watershed analysis of the study area was carried out using the Global Mapper15.0. The result shows that the parameters obtained such as the mean area of the sub-catchments is 1.43 ha, the mean length of channel flow is 99.33 m, the mean length of overland flow is 111.81 m, mean upstream elevation for overland flow is 63.30 m, mean downstream elevation for overland flow is 62.37 m and mean downstream elevation for channel flow is 61.12 m. The intensity duration frequency curve of the catchment was developed and a return period of 25 years was used to obtain an average rainfall intensity of 218.81 mm/hr. The peak discharge was obtained as 2.01 m3 /s using rational formula due to the area of the watershed being less than 80 hectares. Finally, several design parameters for the modeled rectangular channel were calculated. The result indicated that the width of the channel is 0.80 m and the depth of the channel is 1.0 m. The developed modeled channel has a design capacity of 2.03 m3 /s which is greater than watershed peak discharge 2.01 m3 /s. The size of the modeled channel was compared with the size of the existing channel and the result revealed that the existing drain was insufficient to carry the discharge from the catchment area due to its design capacity of 0.91m3 /s. It is recommended that the dimension of the existing drain should be increased to meet with the dimension of the modeled drain and a discharge point (safe outlet) should be provided.

The impact of long-term (> 100 yr) irrigation on soil chemical properties was studied on eight plots in the Beli Drim river valley in Kosovo and Metohija near Klina, Serbia. For these studies, soil samples from shallow profiles were collected from only one or two depth zones of the Ah horizon; and from moderately deep and deep profiles, from two to three depth zones for the purpose of comparing irrigated field and non-irrigated meadow lands. Water from the Beli Drim River and surface gravity systems (irrigation furrows or border strip irrigation) were used for irrigation. Chemical variables included determination of pH-H2O, content of CaCO3, content of humus, hydrolytic acidity, sum of basic cations, cation exchange capacity, and base saturation. On irrigated soils, the results of chemical analysis showed on average a small increase in pH-H2O (0.07 pH units), as well as a significant decrease in humus content (2.00-4.75%), sum of basic cations (4.98-12.98%) and cation exchange capacity (12.8%) compared to the non-irrigated land of the study area. Long-term irrigation had no effect on hydrolytic acidity and base saturation in the Ah horizon of the investigated lands. Namely, the mentioned variations in the chemical properties of the investigated soils show that slight processes of reduction in the humus content and reduction of the content of base cations occured. Data on the chemical properties of the investigated soils indicate that the destructive processes of reduction in the humus content and leaching of base cations must be controlled in order to achieve a stable sustainable system of high productivity and prevent their further deterioration.

Published: September 2021

The paper examines hydromorphic soils from the class of gley soils, soil type humogley. The examined soils are located in the protected part of the inundation of the middle course of the Danube. According to the chemical properties of the examined soils, the pH value ranges from 7,64 to 8,15 on average, and with depth there is an increase in alkalinity. The total salts of the examined soils had increased values in the humus horizon and ranged from 0,06 to 0,09%. The texture classes of the humus horizon of these soils are: clay loam to sandy clay loam, while the lower sub-horizons of the gley are textural classes of sandy loam, loamy sand and sand. The influence of the Danube water level on the groundwater level results in high correlation coefficients, which range from 0,67 to 0,88. The groundwater in these soils had the highest level from 28 cm to 70 cm depth, and the lowest level was from 110 to 175 cm deep. The amplitude of groundwater variation during the year in the examined humogley soils ranges from 66 to 132 cm. Groundwater quality classes according to U.S. Salinity Laboratories are unfavorable and range from C3S1 to C4S1, ie salt to very salty water with low sodium content, and according to the FAO classification the water quality is such that there is a moderate need for restriction. High groundwater level above the critical level, as well as watering the soil with water of this quality can have an impact on salinization of the surface horizon of humogley soil of the examined area.

The specifics of the soil and climatic conditions of the Aral sea region, Kazakhstan, primarily associated with salinization, various types of droughts, uneven distribution of precipitation during the growing season, and late spring frosts, make it necessary to create crop varieties with resistance to biotic and abiotic environmental factors. In this regard, the expansion of the area under crops of nontraditional salt-tolerant grain crops in the Kyzylorda region is one of the main directions of increasing the sustainability of agriculture in the region. Studies have shown that among the grain crops cultivated in the region, spring barley (Hordeum vulgare L.) is a reliable crop that can make the most of the region's bioclimatic resources to form sustainable yields. The purpose of this study is to create a new promising source material of barley based on a comprehensive study of collection material of various ecological and geographical origin by applying various methods of classical breeding. Based on a comprehensive assessment of the collection material of barley, a working collection of 250 varieties with agronomic resistance to environmental stress factors of the Aral Sea region was created. The selected samples are recommended for use in practical breeding in order to increase the adaptive potential of modern barley varieties.

The research was conducted to determine the soil organic carbon (SOC) stocks in relation to the altitude in Serbia. The database included a total of 1,140 soil profiles. SOC were investigated at different the altitudes (0-200 m, 200-500 m, 500-1,000 m, 1,000 - 2.000 m) and at two soil depths (0-30 cm and 0-100 cm). Statistical correlation was done for five regions where locations were grouped according to the spatial distribution. The results showed that the highest mean values of SOC were measured on the terrain that includes mountains with the altitudes of 1,000-2,000 m and covers an area of 11.5% of the territory of Serbia. The lowest obtained result is related to the lowland areas with the largest number of locations. Greater variability in the results of SOC stocks were found at the higher altitudes and the greatest on the low mountains of 500-1,000 m altitude. There is a medium to strong statistical dependence of the altitude with the SOC stocks at two soil depths (0-30 cm and 0-100 cm). The result indicate that the relationship between SOC stocks and altitude varies between the regions. This study shows that altitude is an important factor affecting SOC stocks.

Coronavirus Disease 2019 (COVID-19) pandemic has been ferociously destroying global health and economics. According to World Health Organisation (WHO), until May 2021, more than one hundred million infected cases and 3.2 million deaths have been reported in over 200 countries. Unfortunately, the numbers are still on the rise. Therefore, scientists are making a significant effort in researching accurate, efficient diagnoses. Several studies advocating artificial intelligence proposed COVID diagnosis methods on lung images with high accuracy. Furthermore, some affected areas in the lung images can be detected accurately by segmentation methods. This work has considered state-of-the-art Convolutional Neural Network architectures, combined with the Unet family and Feature Pyramid Network (FPN) for COVID segmentation tasks on Computed Tomography (CT) scanner samples the Italian Society of Medical and Interventional Radiology dataset. The experiments show that the decoder-based Unet family has reached the best (a mean Intersection Over Union (mIoU) of 0.9234, 0.9032 in dice score, and a recall of 0.9349) with a combination between SE ResNeXt and Unet++. The decoder with the Unet family obtained better COVID segmentation performance in comparison with Feature Pyramid Network. Furthermore, the proposed method outperforms recent segmentation state-of-the-art approaches such as the SegNet-based network, ADID-UNET, and A-SegNet + FTL. Therefore, it is expected to provide good segmentation visualizations of medical images.
