Authors: CİVELEKLER Ebru , PEKKAN Emrah
Published: February 2022

Recently, three-dimensional visualization of soil characteristics has been widely used in geotechnical engineering applications. In this study, the 3-D visualization of Tepebaşı area soils, the province of Eskişehir, is prepared using SPT data, soil classes through Environmental Visualization System-Mining Visualization System (EVS-MVS) programs. Moreover, the local soil conditions were classified according to the Turkish Earthquake Code 2018 and digitized using Geographical Information Systems (GIS) and the data observed by the field and laboratory tests. The local soil conditions are observed utilizing the map classified according to the Turkish Earthquake Code 2018. By taking these 3D visuals and maps into consideration, it is determined that soil is alluvial. The ground water level is high, especially in the city center; the local soil type is ZD, ZE and ZF, according to the Turkish Earthquake Code (2018). Examination of the 3D visuals and maps reveal soil’s the changing soil profile with a gradual gradation from fine grain soil (clayey and silty) at the surface; to coarse grain soil (sandy and gravelly). Therefore, the 3D visuals and maps established in the scope of this study may provide preliminary information to the researchers and pragmatists in the area.

Published: February 2022

Багаторічними дослідженнями (2005–2020 рр.) встановлено особливості формування домінантного комплексу фіто-планктону різнотипних водних об’єктів Українського Полісся (річок, озер, водосховищ і водойм, утворених на місці затоплених кар’єрів із видобутку піску, гранітів та ільменітів). У різні сезони до домінуючих належало 216 видів, що складає 24,6 % від їх зага-льного числа, ідентифікованих у складі фітопланктону водойм та водотоків регіону. У флористичному відношенні у складі доміна-нтних комплексів найбагатше представлені відділи діатомових (29,7 % від загальної кількості видів-домінантів), зелених (24,1 %) і евгленових водоростей (19,4 %). Таке співвідношення властиве водоростевим угрупованням планктону всіх досліджуваних типів водних екосистем.

Найбільша подібність складу домінантних комплексів властива планктону річок і створених на них водосховищ (k=0,48), та-кож встановлено значну подібність між списками видів-домінантів озер і водойм, утворених на місці затоплених кар’єрів (k=0,41).

У більшості досліджених водних об’єктів насиченість складу домінантних комплексів суттєво не змінювалася впродовж ве-гетаційних сезонів, лише у Дідовому та Острівському озерах у літній період відзначали збільшення числа видів, які формують до-мінантний комплекс, із подальшим його збідненням восени.

У складі домінантних комплексів фітопланктону виявлено 11 видових і внутрішньовидових таксонів водоростей, нових для Українського Полісся. Поява у складі домінантних комплексів нових для регіону видів значною мірою зумовлена змінами гідроло-гічного й гідрохімічного режимів водойм і водотоків, пов’язаними з зарегулюванням, осушувальною меліорацією, змінами клімату, а також появою штучних водойм на місці затоплених кар’єрів із видобутку корисних копалин.

Йододефіцитні стани та інсулінорезистентність – це патофізіологічні процеси, які зумовлюють розвиток комплексу захворювань та порушень, тому детальне вивчення біохімічних механізмів їх виникнення та розвитку є надзвичайно актуальним. Метою цієї роботи було визначення вмісту продуктів окисної модифікації білків, показників ліпідного спектру та рівня амінотран-сфераз у щурів з інсулінорезистентністю, йододефіцитом та інсулінорезистентністю у поєднанні з йододефіцитом. У крові та гепа-тоцитах щурів визначали вміст продуктів окисної модифікації білків. У крові визначали вміст триацилгліцеролів, загального холес-теролу, ліпопротеїдів низької щільності та ліпопротеїдів високої щільності, активність аспартатамінотрансферази та аланінамінотрансферази.Встановлено, що у крові та гепатоцитах щурів з інсулінорезистентністю, йододефіцитом та інсулінорезистентністю у поєд-нанні з йододефіцитом зростає рівень продуктів ОМБ. У крові тварин трьох дослідних груп зростає активність аспартатамінотран-сферази та аланінамінотрансферази, вміст холестеролу, триацилгліцеролів, ЛПНЩ, знижується вміст ЛПВЩ.

Information relations in agricultural sector of the Kyrgyz Republic (KR) needs further development based on the digitalization processes taking place in the society. Spread of COVID-19 pandemic introduced a number of economic adjustments to the country’s digital interactions, which significantly influenced the development of information and consulting services in the industry. Cooperation of the Kyrgyz Republic with the states of the Eurasian Economic Union presupposes close interaction on issues of regulation of the common agricultural market and development of international trade in the field of agriculture, which also affects digitalization of the country’s economy. The paper presents the results of methodological study on development of information and consulting services in the agricultural sector, analysis of organizational structure of the country’s agriculture according to categories of farms, and entities requiring these services have been determined. Recommendations are proposed for digitalization of the industry, taking into account development of information and consulting services, based on the current state of agricultural production, as son as the main consumers of information services turn to be peasant (farmer) households as the main producers of agricultural products. Building a system of information and consulting services will contribute to development of its own market for agricultural products, processing information from agricultural producers and consumers of agricultural products, creating profitable trade relations and marketing of agricultural products.

In the market conditions of dairy cattle breeding, the problem of increasing productivity comes to the fore of cost-effective milk production. As best practices and zootechnical studies show, the productivity of cows is already laid at the level of raising calves of the dairy period. The main feed for calves of the dairy period is currently whole milk, but due to its deficiency, various substitutes based on skimmed milk powder with various additives of vitamins and trace elements are produced. However, due to high cost, the use of whole milk replacers has not been widely used.  In this regard, to increase profitability of dairy cattle breeding, as well as for accelerated development, calves are accustomed to consuming vegetable feeds. Since plant-based feeds are difficult to digest in a young body, they must be processed into easily digestible. The paper presents an innovative technology and an automated set of equipment for production of easily digestible concentrate based on local grain raw materials for replacement young animals. It has been determined that the use of an innovative automated set of equipment for production of easily digestible concentrate for feeding calves of the dairy period contributes to: faster development of rumen, higher digestibility of grain components due to proper processing, since during preparation of the concentrate, protein denaturation, inactivation of anti-nutritional substances and starch hydrolysis to maltose occur; obtaining optimal weight gain of calves (over 700 g), which will lead to creation of a basis for future high milk productivity of cows; simplification of calf feeding technology; reducing the consumption of milk or whole milk replacer for feeding calves.

Published: February 2022

In the Republic of Belarus, as well as around the world, there is a continuous search for ways and methods of efficient struggle against the varroatous invasion of bees, however, no significant decisions are found in this struggle. In the context of this problem, scientific studies were conducted on development of modern technology of beekeeping on the background of spread varroatous invasion. Technological methods are proposed in the fight against varroatous invasion of bees, proving efficiency of the joint use of zoothechnical, biological and mechanical methods of combating the Varroa tick. It has been shown that purposeful rearing and selection of the drone brood reliably reduces the tick contamination of bee families by 5.7-17.4%. It has been substantiated that the use of intraulic pollen collector significantly reduces the number of ticks in the bees families, especially in the early spring period, when the ticks are mainly located on bees and are especially vulnerable to mechanical impact. The use of the feeding frame allows to purposefully obtain, conveniently and easily select the drone brood, and along with the drone brood, remove the Varroa tick form the bee nest. The use of the developed technology will allowed to reduce the number of tick, obtain additional products in the form of a homogenate of trutone larvae. Such system will increase the preservation of bee families, productivity of honey harvest and, as a result, increase the profitability of beekeeping production, as well as the effectiveness of pollination of entomophilic agricultural crops and their yield.

Published: February 2022

The present study aimed to evaluate the effect of prey density on the biology and functional response of green lacewing, Mallada boninensis (Okamato) (Neuroptera: Chrysopidae). Newly emerged larvae of M. boninensis were fed 20, 30, 40, 50, 60, 70, 80, 90 and 100 fresh eggs of Corcyra cephalonica (Lepidoptera: Gelechiidae) in plastic vials. It was observed that the prey density had a significant effect on the positive consumption rate, development, and fecundity of M. boninensis. In general, maximum consumption with shortest developmental time, maximum fecundity, and most extended adult longevity was observed as prey density increased. The predatory potential was high when the prey density was raised. The daily predation rate of M. boninensis increased slowly during the first two instars and reached its peak in the third larval instar. The results indicated that M. boninensis feeding potential and developmental period might vary from 6.00 to 11.33 days based on food density and having a difference in per day consumption. The 100 Corcyra eggs/day treatment had the highest egg intake of 87.88 eggs per day, followed by 90 eggs/day (79.33 eggs) and 80 egg day-1 (69.75 eggs).

Torenia fournieri is an important ornamental plant in Bangladesh that can grow in a variety of soils in moist areas. It is an extensively studied plant species to investigate fertilization and movement of chromosome. This investigation was carried out to establish a suitable protocol for large scale in vitro regeneration. In vitro mass propagation is one of the best biotechnological methods that can be ensured rapid multiplication of disease-free propagules and genetically identical plant production for plant breeding. In vitro plant regeneration in Torenia was obtained on MS medium supplemented with 2.0 mg/l BA using nodal segments as explants. Maximum 95% of the explants were produced multiple shoots in this medium. The maximum number (12) of shoot per explant and the maximum shoot length of 5.5 cm were observed after 60 days of culture. The well-rooted were found when strong and healthy shoots were transferred into half strength of MS+ 1.0 mg/l IBA. The maximum number (18) of root per shoot and the maximum root length of 4.83 cm were recorded in this medium after 30 days of culture whilst 90% of shoots induced root. In vitro raised plantlets did not show any morphological variation and 90% of plantlets was survived in the natural environment. In this study, rapid multiplication of planting material in Torenia through in vitro propagation techniques such as shoot initiation, multiplication, rooting, hardening and optimizing the concentrations and combinations of plant growth regulators is developed. This regeneration protocol will be helpful in in vitro mutagenesis technique to create new variation of this plant within short time cycle.

Authors: Ohemu Godwin Pius  , Fajoyomi Bridget Uredo-ojo
Published: February 2022

The widespread use of antibiotics as prophylactics and therapeutic agents has increased the risk of emergence and spread of resistant bacteria leading to prolonged and expensive treatment and greater risk of death in humans. The aim of this study was to determine the antimicrobial effect of the methanol extract of Jatropha tanjorensis leaves on multi antibiotic resistant bacteria isolated from poultry droppings. Multi antibiotic resistant bacterial isolates from poultry dropping already identified from previous research were used. The plant extract was obtained by soxhlet extraction process, susceptibility test was caried out using well in agar diffusion method. The percentage yield of the plant extract using soxhlet extraction process with methanol was 22.84%. The qualitative phytochemical analysis revealed the presence of bioactive compounds such as tannins, flavonoids, cardenolide, steroids, terpenoids, anthraquinone, alkaloids, fixed oil and carbohydrate. The extract showed competitive zones of inhibition on Escherichia fergusonii, Stenotrophomonas maltophilia, Enterobacter clocae, Lysinibacillus sphaericus and Salmonella typhimerium. Enterobacter clocae had the highest zone of inhibition of 17mm at a concentration of 100mg/ml, 10mm at 80mg/ml and 8mm at 50 mg/ml. Stenotrophomonas maltophilia had the lowest zone of inhibition of 10mm at 100mg/ml, 8mm at 80mg/l and 7mm at 50mg/ml. These zones of inhibitions show the antimicrobial potency of Jatropha tajorensis on antibiotic resistant bacteria. Compared with synthetic antibiotics or inorganic chemicals, this plant-derived extract is natural, less toxic, typically residue free with high rate of metabolism. The result of this study gives credence to claims of the medicinal and nutritional properties of Jatropha tanjorensis.
Validação estatística de dados do Tropical Rainfall Measuring Mission (TRMM) para a bacia hidrográfica do Rio Jordão – Paraná – Brasil
Authors: Toledo Bruno Henrique Costa , Andrade Aparecido Ribeiro
Published: February 2022

Registros de precipitação pluvial em áreas pouco acessíveis, normalmente não apresentam uma boa distribuição espacial dos postos de coleta, principalmente pela questão físiográfica (relevo e rede de drenagem, por exemplo). Entretanto, aspectos estruturais, como baixo investimento em redes de monitoramento, também são comuns. A área do presente estudo (Bacia Hidrográfica do Rio Jordão – BHRJ), localizada na região centro-sul do estado do Paraná – Brasil, possui problemas correlatos. Nesse sentido, o objetivo dessa pesquisa foi validar um método de ajuste e correção entre fontes de dados distintas, focando a correção das informações provenientes do Tropical Rainfall Measuring Mission (TRMM), associadas aos de postos pluviométricos em superfície, buscando melhorar a representação espacial. Esse procedimento foi realizado com base na criação de equações lógicas e aplicação de testes estatísticos. Os dados do sensor TRMM foram analisados, ajustados e comparados com dados de pluviômetros localizados no entorno e dentro da BHRJ para o período de 2009 a 2018. Os resultados obtidos por meio de técnicas estatísticas, como a correlação linear (r), Coeficiente de Determinação (r²), Erro Médio Absoluto (EMA), foi considerado satisfatório, com valores de r² próximo de 90%. Dessa forma, identificou-se que a região de estudo tem elevada variabilidade temporal e espacial da precipitação pluvial, mas as técnicas de ajustes utilizadas propiciaram melhor representação espacial, possibilitando a utilização dos dados oriundos de sensores remotos em complemento aos de postos de superfície, com bom nível de confiança.

O objetivo principal neste trabalho foi aplicar análises estatísticas para analisar a variabilidade da precipitação e temperatura média do ar em Campina Grande, Paraíba e Petrolina, Pernambuco. Para isso utilizaram-se dados mensais das referidas variáveis de ambas as localidades, disponibilizados pela Empresa Brasileira de Agropecuária (EMBRAPA), no período de 1977 a 2014. De posse dos dados, aplicou-se estatísticas descritivas (média, mediana, desvio padrão e anomalias) e inferenciais (T-Student, Mann-Kendall e ANOVA) para caracterizar e identificar diferenças climáticas entre as localidades e a variabilidade dentro da localidade. Entre os principais resultados destacam-se que, em termos médios Campina Grande é mais chuvosa e Petrolina é mais quente, com significância estatística de 5%. A distribuição das chuvas também é distinta, em Campina Grande o período mais chuvoso ocorre de março a julho e em Petrolina as chuvas se concentram entre dezembro a abril. A temperatura média do ar em Campina Grande apresentou tendência de aumento nas quatro estações do ano, com significância estatística de 5%. As aplicações estatísticas foram cruciais para análises e obtenção dos resultados climatológicos.

Published: February 2022

Neste estudo avaliou-se a variabilidade climática nos municípios de Manaus (AM) e Belém (PA), utilizando dados de temperatura média compensada e precipitação total disponibilizados pelo Instituto Nacional de Meteorologia – INMET. O recorte temporal analisado no estudo foi de 1961 a 2020. Utilizando técnicas de estatística básica foi produzida uma análise da temperatura e precipitação média decadal, incluindo a comparação entre os municípios com relação às variáveis meteorológicas. Na cidade de Manaus observou-se um aumento na temperatura média decadal mais pronunciado em relação a Belém. Por outro lado, verificou-se um aumento na precipitação média decadal mais acentuado em Belém quando comparada a Manaus. Na análise individual Manaus apresentou um aumento na temperatura média decadal e comportamento oscilante em relação a precipitação. Em Belém observou-se aumento na temperatura média decadal e aumento na precipitação. As duas variáveis apresentaram leve oscilação entre as décadas nas duas cidades analisadas. Tais resultados indicam uma alteração no microclima local de Manaus e Belém possivelmente causadas pela expansão urbana, aumento populacional e mudança no uso do solo.

ACEMHÖYÜK ERKEN TUNÇ ÇAĞI III BOYA BEZEKLİ SERAMİK GRUPLARI ÜZERİNE BİR DEĞERLENDİRME
Authors: ŞENER Tuğçe
Published: February 2022

Erken Tunç Çağı III (MÖ 2450-2000) Anadolu toplumlarının kültür, ekonomi, teknoloji gibi alanlara yayılan yenilikler tarafından derinden etkilendiği hareketli bir döneme işaret etmektedir. Bu dönemde, maddi kültürün çeşitli unsurlarını biçimlendiren gelişmelerin seramik üretimini de etkilediği görülmektedir. Orta Anadolu Bölgesi’nin anahtar Erken Tunç Çağı III yerleşimleri arasında yer alan Alişar, Kültepe gibi merkezlere bakıldığında, boya bezekli seramiklerin dönem boyunca yaygın bir şekilde kullanıldığı görülmektedir. Söz konusu yerleşimlerde tanımlanan tablonun bölgenin diğer yerleşimleri için de ana hatlarıyla geçerli olduğu ifade etmek mümkün görünmektedir.

Tuz Gölü’nün hemen güneyinde yer alan Acemhöyük, Orta Anadolu Bölgesi’nin en büyük höyüklerinden biridir. Acemhöyük’te yürütülen arkeolojik araştırmalar, kentin Asur Ticaret Kolonileri Çağı boyunca yerel bir krallık merkezi olduğuna işaret etmiştir. MÖ III. binyıl tabakalarında gerçekleştirilen kazılar sonucunda ise yerleşimin genel özelliklerinin yanı sıra Erken Tunç Çağı seramik gruplarının tanımlanması mümkün olmuştur.

Gas and particulate matter (PM) emissions from Masaya volcano, Nicaragua, cause substantial regional volcanic air pollution (VAP). We evaluate the suitability of low-cost SO2 and PM sensors for a continuous air-quality network. The network was deployed for six months in five populated areas (4-16 km from crater). The SO2 sensors failed and recorded erroneous values on multiple occasions, likely due to corrosion, requiring significant maintenance commitment. The PM sensors were found to be robust but data required correction for humidity. SO2 measurements could not be used as stand-alone tools to detect occurrence of VAP episodes (VAPE), but SO2/PM correlation reliably achieved this at near-field stations, as confirmed by meteorological forecasts and satellite imagery. Above-background PM concentrations reliably identified VAPE at both near-field and far-field stations. We suggest that a continuous network can be built from a combination of low-cost PM and SO2 sensors with a greater number of PM-only sensors.

Standar tersebut antara lain, guru wajib menguasai materi, struktur konsep, dan pola pikir keilmuan yang dapat mendukung proses pembelajaran matematika. Standar profesionalitas guru tersebut ditujukan agar guru mampu membantu dan membimbing peserta didik dalam mencapai tujuan belajarnya. Namun, hasil observasi mahasiswa calon guru matematika di salah satu universitas yang berada di Malang menunjukkan jika mereka masih mengalami kesulitan dalam membuat representasi matematis. Oleh karena itu penelitian ini dilakukan untuk mendeskripsikan kemampuan representasi simbolik mahasiswa calon guru ditinjau dari perbedaan gender. Perbedaan gender dalam penelitian ini untuk mendeskripsikan apakah perbedaan gender dapat mempengaruhi kemampuan seseorang dalam membuat representasi matematis. Pendekatan Mixed Methods dengan jenis penelitian deskriptif kuantitatif dipilih untuk menjabarkan tujuan penelitian. Data dikumpulkan melalui kegiatan dokumentasi dan tes. Tes diberikan kepada 35 mahasiswa calon guru dengan jurusan Pendidikan Matematika di salah satu universitas yang ada di Malang. Sebanyak 4 mahasiswa yang terdiri dari 2 mahasiswa perempuan dan 2 mahasiswa laki-laki dipilih untuk dikaji lebih rinci. Hasil penelitian menunjukkan bahwa mahasiswa perempuan lebih ulet dan teliti dalam menyelesaikan masalah matematis. Mereka mampu membuat representasi simbolik dari masalah yang diberikan. Mahasiswa perempuan juga membuat interpretasi dari simbol-simbol yang digunakan dalam selesaian masalah. Berbeda dengan mahasiswa laki-laki. Mereka lebih cenderung langsung menginputkan bilangan-bilangan yang termuat di soal kedalam algoritma selesaian masalah.
