The process of the oil field operation at the late stage is characterized by a significant content of mechanical impurities in the extracted raw materials and a high rate of water encroachment. Water encroachment plays a sig-nificant role in the processes of formation sand carry-over and the destruction of incompetent rocks of productive horizons in deposits. Today, to intensify the drainage of formation fluid from production wells, it is necessary to increase the depth of descent and to use more productive pumps. However, this leads to the growth of the draw down pressure and, as a rule, to more intensive sloughing of mechanical impurities out of the reservoir. First of all, the sand taken out of the formation is a highly abrasive agent, which causes the wear not only of the pump elements, but also of the tubings, valves, throttles, etc. Predicting the impact of mechanical impurities on the ele-ments of the pumping equipment for oil production is a complex task that requires consideration of many different factors. The sand which is carried out of wells is accumulated in the pipelines. Besides, it is accumulated in meas-uring units, separators, valves and other parts of group metering and pumping units. Process tanks and reservoirs at oil or condensate treatment plants are clogged with sand. To combat sloughing of sand, in most cases the meth-od of filtration is used. This method is not the most effective, but it is reliable, low cost, and environmentally friendly. Several constructions of downhole filters are analyzed. To evaluate the efficiency of the downhole filter, its research is carried out using simulation modeling. The dependence of the number of sloughed particles on their diameter is established in accordance with the hydrodynamic processes and characteristics of the working envi-ronment.

Охарактеризовано вплив водонапірної системи на характер залежності приведеного середнього пластового тиску від накопиченого видобутку газу з родовища. Зроблено припущення, що незначний вплив законтурної водоносної частини покладу не впливає на характер залежності приведеного середнього пластового тиску від накопиченого видобутку газу, і характер цієї залежності повною мірою характеризує газовий режим розробки покладу. Використання матеріального балансу в такому випадку призводить до завищення початкових запасів газу, оскільки в процесі впровадження певного об'єму води в продуктивну газонасичену частину покладу частково компенсує зниження пластового тиску внаслідок відбору газу. Таким чином, не знаючи достовірних початкових запасів газу, неможливо раціонально проектувати систему розробки та надавати рекомендації щодо вдосконалення системи розробки родовища, що потребує значних капіталов-кладень. Для підтвердження цього припущення створено синтетичну тривимірну  модель газового покладу. Створена 3D модель газового покладу включає в себе об'єм води нижче газоводяного контакту, який обме-жений розмірами моделі та додатково з метою проведення комплексного аналізу використано аналітичний акюфер Фетковича об’ємом 5 млн м3 та 25 млн м3  відповідно, з однаковим індексом продуктивності. Акюфери підключені до межі моделі з південно-східного напрямку. За результатами проведених досліджень на основі створеної 3D моделі здійснено графоаналітичну оцінку дренованих запасів газу. Аналізуючи отри-мані результати, автори  повною мірою підтвердили зроблене припущення, про те, що незначний вплив во-донапірної системи не пливає на характер залежності приведеного середнього пластового тиску від нако-пиченого видобутку газу з родовища. За  результатами проведених досліджень зроблено оцінку можливої величини похибки, яка допускається в результаті оцінки запасів газу за методом падіння пластового тиску. Згідно результатів моделювання розробки родовища величина похибки може складати до 19,47% від дос-товірних початкових запасів газу в моделі. Дане відхилення суттєво перевищує допустимі межі і може призвести до прийняття неправильних рішень щодо подальшої розробки родовища.

Quantitative and qualitative characteristics of multi-ton materials in Ukraine and in Ivano-Frankivsk region, which Quantitative and qualitative characteristics of multi-ton materials in Ukraine and in Ivano-Frankivsk region, which contain energy components, are given. It is proposed to process water treatment sludges containing petro-leum products by preparing a raw material mixture from the following man-made substances: oil sludge, ash, zeo-lite screenings, calcium-containing compounds and viscous materials. The optimal composition of the raw material mixture is as follows: as a filler for construction products (concrete): ash – 60-65 %, liquid glass s olution – 5-7 %, limestone dust – 3-5 %, organic additives – 7-10 %, soda ash – 10-12 %, which is granulated and heat t reated at 120-140 °C. The research results and technical char acteristics of the obtained granular materials, which are formed from a mixture containing a significant amount of hydrocarbon sludge, have lower strength, but greater porosity and lower thermal conductivity. Granules from a mixture № 4-7 are characterized by higher strength, and due to their properties they belong to the structural and thermal insulation materials. The technology of obtaining a raw material mixture for soda production is based on the LeBlanc process – the interaction in the seco nd stage of sodium sulfate, carbon and calcium carbonate with the formation of calcium sulfide, sodium carbonate and carbon (IV) oxide. It is proposed to prepare a raw mixture for the production of sodium carbonate from sodium sulfate con-taining petroleum product, which is formed by the technology of obtaining oxygen-containing additives, and sludge containing petroleum products, which will provide a high temperature during the soda production process. The processing of sludge from oil refining and energy facilities into granular materials shows that they can be used in the construction industry and soda production, which reduces the energy consumption of the processes of obtaining such materials.

The introduction of modern methods for field assessment of winter wheat genotypes is an integral part of improving the quality of the breeding process. The creation, adaptation and use of innovative screening technologies in breeding is becoming increasingly popular and allows the breeder to more widely and objectively evaluate the original forms and newly created material. Important for winter is the autumn period, when under favorable weather conditions (gradual decrease in temperature) there is a slowdown in the growth rate of winter wheat, changing physiological and biochemical processes in the plant, which contribute to its transition to hibernation. The state of winter wheat crops (morpho-biometric indicators of plants) in the autumn is largely decisive in the formation of a sufficient level of winter hardiness, and thus affects the further productivity of the crop. According to the results of analysis of morpho-biological and spectral analysis data, it was established that before overwintering the best condition for the first sowing period was winter wheat plants: MIP Lada (NDVI = 0.48), erythrospermum line 55023 (NDVI = 0.46), Lutesens 60049 (NDVI = 0.46), varieties MIP Distinction (NDVI = 0.46) MIP Jubilee (NDVI = 0.46), MIP Dnipryanka (NDVI = 0.46) and line Lutesens 55198 (MIP Gift) (NDVI = 0, 47). In the standard variety Podolyanka, the index value was at the level of 0.45. During the second sowing period, the following varieties were identified: MIP Assol (NDVI = 0.32), Ballad Myronivska (NDVI = 0.32), Erythrospermum 55023 (NDVI = 0.33), MIP Lada (NDVI = 0.33), MIP Jubilejna ( NDVI = 0.32) and Lutesens 55198 (MIP Gift) (NDVI = 0.32) and Lutesens 60107 (NDVI = 0.32). NDVI index of Podolyanka variety was at the level of 0.32.

The live weight and milk production index of black-and-white and Tatarstan type cows of the Kholmogory breed with different genotypes for genes CSN3, DGAT1, PRL, GH were studied. It was found that cows with the homozygous genotype CSN3 AA, DGAT1 AA, PRL AA, GH LL are characterized by a high milk yield index. Unlike other marker genes, the somatotropin gene had a greater effect on the body weight and milk production index of cows. Thus, in terms of live weight in the black-and-white breed, the superiority of individuals with the GH LL genotype by 43 kg (P <0.001), GH LV by 42 kg (P <0.001) was noted, and in terms of milk production, the advantage of cows with the GH LL genotype (984 and 1008) over GH LV by 40 (P <0.01); on the Kholmogory breed above GH LV by 26 (P <0.05), GH VV by 42 (P <0.05). Consequently, cows with allelic A variant of the CSN3, DGAT1, PRL genes and allelic L GH genes in their genomes exhibit high milk production at optimal live weight.

Antioxidant drugs "E-selenium" and Catosal help to reduce LPO processes in the body of pregnant ewes. Were formed 3 groups of animals - analogs, three heads each (control and two experimental). Ewes of experimental group 1 were injected intramuscularly with the preparation "E-selenium" in a dose of 1 ml per head once a month for 2 months, starting from the third month of pregnancy. The animals of the second experimental group in the same periods were injected with the drug "Catosal" intramuscularly at a dose of 4 ml per head once a month for 2 months. The feeding of animals of all groups was the same, balanced in nutrients and corresponded to the norms of the Russian Academy of Agricultural Sciences. The experiment lasted 155 days. There was an increase in the production of DC in the 3rd month of pregnancy in the control group of animals in comparison with the experimental ones, in its so-called "peak", it was significantly higher than in the 1st month, in experimental group 1 by 9.8 %, with experimental group 2 by 9.71%, in control by 18.75 %. During this crucial period, the laying of fruits occurs in the body of ewes, which is reflected in the level of its own antioxidant system. A similar increase can be traced in the case of MDA, which is a secondary oxidation product and is often formed from diene conjugates. The difference in the control group in comparison with the experimental group 1 was 7.48 % and the experimental group 2 13.84 %. Starting from the 4th and 5th months of pregnancy, as the intensity of LPO processes increased, the concentration of DC and MDA production decreased in the experimental groups and especially in the experimental group 2.

The study of the main technological feature of the Kholmogorsky breed of the Tatarstan type-milk ejection intensity-showed that its increased variability is characterized by high-blood crossbreeds, as well as animals of the Astronaut and Sovering lines. The high and low genetic potential of parental productivity reduces the variability of milk ejection intensity. However, selection for an increase in milk content will not be accompanied by an improvement in the intensity of milk ejection, since the established phenotypic correlation is mainly negative or positive at a low level. In this regard, it is necessary to control both productive and technological characteristics.

Mass antibacterial therapy carried out according to therapeutic and preventive schemes is considered to be a highly effective and the most rational measure for controlling infectious diseases in the conditions of large-scale industrial pig breeding. It was found that the long-term intramuscular use of the drug Tulatrin in a therapeutic and three-fold therapeutic dose does not have a pronounced pathological effect on pigs. During the experiment, no animal deaths and manifestations of clinical signs of intoxication (depression, vomiting, salivation, diarrhea, etc.) were noted. The animals were active and ate food well. The live weight of piglets in experimental groups does not significantly differ from the animals that were kept in the control groups. The liver is the most sensitive to the action of tulatromyc in with prolonged intake of the drug in higher doses, which is confirmed by the results of biochemical studies. However, the intrinsic hepatotoxicity associated with the use of high doses, or with prolonged use, is characteristic of all drugs of the macrolide group. It should be noted that in this case, the maximum increase in marker liver enzymes does not exceed 10 % of the upper limit of the norm, so we can say that the liver damage is of a trace nature, since the clinical significance is an increase in liver samples by at least 2 times. Also, the increase in total protein was not fatal and did not affect the change in the clinical status of animals. We did not note the death of animals and the manifestation of clinical signs of intoxication and hepatopathy. Tulatrin is one of the safe medicines, and is characterized by good tolerability. The results obtained confirm the safety of using the drug in the recommended dosage regimen.

Published: September 2021

The present study was conducted to evaluate the effects of different dietary calcium levels on the growth and survival rate of black apple snails (Pila polita) in the grow-out period. There were 3 replicates for each treatment and the snails were fed with five calcium levels (% dry matter) in diet as follows: 1% (Ca1), 3% (Ca3), 5% (Ca5), 7% (Ca7), and 9% (Ca9). Two-month-old juveniles with an average initial body weight of 2.13g, shell height of 21.71mm, and shell width of 16.35mm were reared in tarpaulin tanks (1 × 1 × 1m; 40cm water depth) at the density of 100 individuals per tank. After 4 months of the rearing period, the average body weight, shell height, and shell width of the snails reached the highest values in the Ca5 treatment (28.43 g, 54.97 mm, and 40.09mm, respectively) and these values were significantly different compared to the remaining calcium contents (Ca1, Ca3, Ca7, and Ca9). The survival rate of the snails in Ca3 (75.7%) was higher than in Ca1 and Ca7 (74.7%), Ca5 (73.7%), and Ca9 (71.7%). However, the survival rate was not significantly different among the treatments. Snails in Ca5 obtained the highest productivity (2.88 kg m-2) and this value was significantly different from Ca1 (2.55 kg m-2) and Ca9 (2.35 kg m-2). The results of this study showed that the growth rate and productivity of black apple snails were highest when they consumed a diet containing 5% calcium. The optimum requirement of calcium for the black apple snails in the grow-out period was 4.51%.

The purpose of this study was to apply the modified Kostiakov method to determine the soil infiltration rate and permeated water amount of Thuong River alluvial soil for orange plantations in Lang Giang district, Bac Giang province, Vietnam. The soil particle size ranged from 0.02 to 2.00mm mainly found in the surface horizon (>77.7%). The soil was slightly acidic in the surface horizon, and highly acidic in the subsurface horizons (pHKCl from 3.42 to 4.79). The organic matter content of the surface horizon was mederate, while it was very low in the other horizons. The total nitrogen (N) content was low (0.15%) in the surface horizon and very low in the subsurface horizons (0.02-0.06%) while the available N was medium. The total phosphorus (P) content in the surface horizon was high (0.4%) and medium in the other horizons. Available P in the surface horizon was high (18.6mg per 100g soil) and decreased in lower depths to only 0.3mg per 100g soil in the deepest (5th) horizon. The total and available potassium measurements were very low. A filtration characteristic model was developed by using the modified Kostiakov method for alluvial soil. The constant values a, a, and b of the equation y = ata + b were 0.8035, 0.758, and 0.00346, respectively, which were smaller than 1. The average percentage difference between the actual and calculated values by the model was only 0.141%, indicating that the calculated values can accurately predict the actual data measurements in the field.

Cassava is Africa’s most important food security crop and sustains about 700 million people globally. Survey interviews of 320 farmers in three regions of Tanzania to identify their production characteristics, and interviews with 20 international whitefly/virus experts were conductedto identify adaptation strategies to lessen the impacts of cassava whiteflies and viruses due to climate change in Tanzania. Structured and pre-tested interview schedules were conducted using a multistage sampling technique. Most of the farmers (66.8%) produced cassava primarily for food, and relied mainly on their friends (43.8%) and their farms (41.9%) for cassava planting materials. Farmers significantly differed in their socio-economic and production characteristics except for gender and access to extension support (P < 0.01). A significant association was found between extension support, sources of planting materials, and reasons for growing cassava with both the control of cassava viruses and the control of whiteflies by the farmers. A significantly higher number of farmers controlled cassava viruses (38.1%) than cassava whiteflies (19.7%). The adaptation strategies most recommended by experts were: integrating pest and disease management programs, phytosanitation, and applying novel vector management techniques.The experts also recommended capacity building through the training of stakeholders, establishing monitoring networks to get updates on cassava pests and disease statuses, incorporating pest and disease adaptation planning into the general agricultural management plans, and developing climate change-pest/disease models for accessing the local and national level impacts that can facilitate more specific adaptation planning in order to enhance the farmers’ adaptive capacities.

The study was conducted to evaluate the germination, physiological responses, yield-related traits, and seed yield of three mungbean varieties, viz. DXVN7, DXVN5, and DX11, under waterlogging coditions in the 2019 Summer. In experiment 1, the seeds of the three mungbean varieties were immersed in distilled water in Petri dishes for 12, 24, 36, 48, and 72h. Afterwards, water was removed and the percentage of germinated seeds was calculated at 84h after sowing. In experiment 2, plants were waterlogged at the seedling stage (25 days after germination) for 3, 6, and 9 days. Waterlogging depth was maintained at 3cm above the soil surface. Physiological traits were determined at the recovery period after termination of waterlogging (45 days after germination). The results showed that waterlogging significantly decreased germination percentages, plant height, root dry weight, leaf relative water content (RWC), SPAD value, Fv/Fm index, leaf photosynthesis, total dry weight, and seed yield of all varieties. Germination percentages at 12 and 24h of waterlogging were not significantly affected, whereas germination was significantly reduced at up to 36h of waterlogging. Seventy-two hours of waterlogging caused failure in germination. Nine days of waterlogging at the seedling stage adversely affected the physiological traits and seed yield of the mungbean varieties with 31% of yield reduction. Meanwhile, plants grew better at 3 days of waterlogging. Among the three varieties, DXVN7 showed the best adaptability under waterlogging conditions, attaining the highest seed germination and yield.

Spotted sea bass (Lateolabrax maculatus, McClelland, 1844) is a species belonging to the genus Lateolabrax (Lateolabracidae), and is characterized by the many distinct black spots on the bodies of mature fish. For the first time, six specimens have been recorded in Quang Ninh province. The specimens were collected from Luon Cave in Bai Tu Long National Park in May-June 2019. The new specimens collected from Quang Ninh, Vietnam are different from the recorded specimens from Japan, Korea, Taiwan, and China in terms of lateral line scales (LLS) as the samples collected in Quang Ninh, Vietnam have 94-97 scales and the samples collected from the other countries have 66-82 scales. Phylogenetic analysis of the 16S rDNA sequence confirmed that all of the samples collected in Quang Ninh, Vietnam belonged to the species of spotted sea bass.

Published: September 2021

This study examined the effectiveness of different antioxidative compounds, namely 0.2% BHA (Butylated hydroxyanisole) + BHT (butylated hydroxytoluene), 0.03% α – tocopherol, and 3% and 6% tea seed oil (TSO) on the oxidative stability of vegetable oils. Four commonly used oils, viz. rapeseed oil (RSO), peanut oil (PNO), sunflower oil (SFO),  and soybean oil (SBO), were assessed by the Schall Oven test method and monitored during the 12-day preservation period under 60°C. The total oxidation values (TOTOX) of the samples treated with 6% TSO were lower than those treated with 0.2% BHA+BHT. The results indicated the potential of TSO as a novel natural antioxidant for dietary vegetable oils. Our study also suggested that TSO could serve as an effective substitution for currently used synthetic antioxidants such as BHA and BHT.

Aim: The number of studies on the epidemiological and clinical data of amyotrophic lateral sclerosis (ALS) patients in Turkey is quite low and the studies on this subject reflect the data of western regions of Turkey. In this study, we aimed to present the demographic, clinical and mortality features of ALS patients diagnosed in the last 10 years in a large reference hospital in the Eastern Anatolia region of Turkey.

Material and Method: 42 ALS patients diagnosed between January 2011 and January 2021 in ………., Faculty of Medicine, Department of Neurology were included in the study. The data of the patients were obtained by retrospectively scanning the patient electronic files registered in the database of our hospital. The age, gender, examination findings, clinical course, treatments they received and the cause of death of the patients were recorded.

Results:26 of ALS patients were men and 16 were women. The mean age of onset was 53.4 ± 12.3 and the mean diagnostic delay was 13.6 ± 6.9 months. 64.2% of the patients had onset in the spinal region, and 35.7% in the bulbar region. Weakness/atrophy of the upper extremity muscles and swallowing difficulty were the most common onset symptoms. All ALS patients were using riluzole. 11 ALS patients died. The mean time between diagnosis and death in patients who died was 27.2 ± 18.6 months. The most common causes of death in ALS patients were pneumonia and sepsis.

Conclusion: Age of onset of ALS was low in our patients. The number of patients in the clinically definite ALS group was the highest. Weakness/atrophy of the upper extremity muscles and swallowing difficulty were the most common onset symptoms. Approximately 2/3 of the patients had spinal, and 1/3 bulbar region onset. There was no significant difference between spinal and bulbar onset patients in terms of gender, age of disease onset, mortality, and life expectancy of patients with death. The rate of using riluzole was high. The most common causes of death in ALS patients were pneumonia and sepsis.

Authors: SÖZEL Hasan , YILMAZ Fatih
Published: September 2021

Aim: Urine Ph (U-pH) is a clinical indicator of acid excretion in the urine and acid load in the diet. The association between low U-pH and net acid secretion with obesity, metabolic syndrome, diabetes, chronic kidney disease, and uric acid nephrolithiasis were showed. The aim of this study is to evaluate the U-pH in patients with different glucose tolerance status.

Materials and methods: This study was designed as single-center, retrospective, and cross-sectional. A total of 1666 subjects (male/female: 531/1135) were divided into three groups according to their OGTT results: group 1 = normal glucose tolerance (NGT), group 2 = prediabetes, group 3 = T2DM. Than subjects were divided into five groups according to their OGTT results: group 1 = NGT, group 2 = impaired fasting glucose (IFG), group 3 = isolated impaired glucose tolerance (IGT), group 4 = both IFG and IGT, and group 5 = T2DM. Additionally, patients were divided into three groups according to their glycated hemoglobin (HbA1c) results: group 1 = NGT, group 2 = prediabetes, and group 3 = T2DM. U-pH values and other outcomes were compared between groups.

Results: Age, male gender, hemoglobin, creatinine, triglycerides, and OGTT groups showed significant association with low U-pH through univariate logistic regression analyses. In model 1 (with OGTT 3 groups), it was found that creatinine (OR: 3.471; % 95 CI: 1.377-8.749; p=0.008) and triglycerides (OR: 1.001; %95 CI: 1-1.003; p = 0.013) were positively associated with low U-pH. Patients with DM (OR:1.437; %95 CI: 1.015-2.035; p=0.041) had higher risk for low U-pH compared to patients with NGT. In Model 2 (with OGTT 5 groups), creatinine (OR:3.423; %95 CI: 1.354-8.654; p = 0.009) and triglycerides (OR:1.001; %95 CI: 1-1.003; p = 0.014) were identified as independent predictive factors associated with low U-pH. Patients with IFG+IGT (OR:1.522; %95 CI: 1.083-2.138; p=0.015) and DM (OR:1.447; %95 CI: 1.022-2.049; p=0.037) had higher risk for low U-pH compared to patients with NGT.

Conclusion: In this study, the frequency of diabetes was found to be increased in patients with low U-pH. More detailed clinical studies are needed to evaluate the relationship between total acid load in the body and U-pH and glucose tolerance disorders.

Published: September 2021

Introduction: Inflammation can adversely affect an operation. The ımportant markers of this

inflammation are CRP (C-reactive peptide), WBC (white blood cell).

Aim: The purpose of this study to predict adhesion related technical difficulties during operation

by comparing preoperative CRP, WBC, Monocyte/Lymphocyte ratio and intra-operative adhesion

findings.

Method: This was a retrospective study. This study includes 116 elective and emergency

cholelithiasis cases whose operation performed at Corum Erol Olcok Training and Research

Hospital in 2020 and 2021. Adhesions on gallbladder were graded during operation and divided

into two groups. Groups graded based on intra-operative findings were compared with

preoperative CRP, WBC, and monocyte/lymphocyte ratio.

Results: The patients were divided into two groups based on the adhesion grade as Grade 1-2

(n=84) and Grade 3-4 (n=32). Average WBC count of Grade 3-4 group was average 11.05 ± 4.45

109

/L and this value was statistically significantly higher (p=0.01) than Grade 1-2 group. Average

CRP value of Grade 3-4 group was found as 50.91 ± 77.25 mg/L and this value was significantly

elevated (p11.55 109

/L), monocyte/lymphocyte ratio (>0.2693) cut-off values.

Conclusion: Preoperative estimation of adhesion grade helps the surgeon considerably. This

study shows that high CRP, WBC, and Mo/Ly ratio values can help the estimation of intensity of

adhesions and challenges during operation.
