Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Zhuravleva L.A.
Published: August 2024

One of the most effective and widespread irrigation methods in the central part of the Russian Federation is sprinkling, and the most common are wide-range circular sprinkler machines. The aim is to optimize the design and height parameters of sprinkler equipment, depending on the operating conditions and irrigated crops. The article considers the optimization of structural and height parameters, machine span lengths depending on the terrain and height of irrigated crops. Agrotechnical patency was assessed by the ratio of agricultural illumination to the height of plants on the most difficult terrain. The conducted studies show that in order to increase the efficiency of operation (reduce slipping and eliminate stopping), as well as eliminate plant jamming, the ratio of the value of agricultural illumination to plant height should be more than 0.7. The results of experimental studies and recommendations of optimal ratios of profile height, machine span, terrain slope and watered crops are presented. When operating on slopes of more than 0.08, the lifting height of the pipeline above the ground is 2.7 m with spans of 59.5 and 65 m is not sufficient, higher-profile models are needed. At the same time, the increase in the profile is limited by metal consumption and traction properties. The value is selected as the minimum possible while ensuring agro technical passability.

Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Smetanin V.I.
Published: August 2024

The purpose of the research is to analyze the causes of land desertification and find ways to curb the rate of desertification and restore previously desolate lands. Areas with a hot climate, minimal precipitation and strong winds are prone to desertification. The annual amount of precipitation does not exceed 200… 50 mm, and in some places they do not happen at all for several years. The soil layer in such territories is poorly developed, vegetation covers less than half of the earth’s surface, and in some cases is practically absent. Groundwater is usually mineralized. In territories with such natural conditions, soil degradation is observed, loss of its fertility, and biodiversity decreases, which ultimately leads to desertification of territories. The article presents the main causes of land degradation and its consequences. The main causes of land degradation and leading to desertification of territories have been identified. Ways to reduce the rate of degradation of agricultural lands and restore previously deserted territories are proposed.

Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Alsadek E.S.
Published: August 2024

The research was carried out to determine the operating conditions of the downstream fastenings behind the expanding stilling basin of the mine-tower spillway of the «16 Tishrin» hydroelectric complex in the Syrian Arab Republic. Calculations were made of permissible velocities that do not cause erosion, based on the average diameters of downstream soil particles and actual velocities measured in the laboratory on a fragmentary model of the fastening unit for the outlet section of a three-point closed spillway with a shaft inlet head at maximum operating flow and operation of the structure along the entire front. The problem of deformations and erosion in the downstream of the 16 Tishrin hydroelectric complex has already existed for many years, and no practical solution has yet been found, except that every two – three years the erosion pit is filled with soil with unstudied fraction sizes. Also, during the experiments, the operation of the stilling basin was assessed under different gate maneuvering schemes. Laboratory confirmation of the proposed practical solution to this problem, ensuring reliable and safe operation of the spillway structure and the entire dam as a whole, emphasizes the relevance of solving this problem for the water economy of the northwestern part of Syria

Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Dubenok N.N.
Published: August 2024

Natural reforestation is one of the important biological processes. Data on the quantitative and qualitative characteristics of natural regeneration in areas undisturbed by economic activity act as a control option for monitoring succession processes in forest stands affected earlier by felling. The purpose of the study is to study the quantitative and qualitative characteristics of natural regeneration in the stands of the core of the Kologrivsky Forest nature reserve. To study natural regeneration, 11 permanent trial plots were used, laid in the Kologrivsky Forest natural monument in 1981‑1984 and restored in 2014‑2019. According to surveys of trial plots in the core of the Kologrivsky Forest nature reserve, it was revealed that almost all of thema re dominated by spruce undergrowth. Also, the layer of the young forest generation is formed by such species as Norway maple (Acer platanoides), small-leaved linden (Tilia cordata), white birch (Betula pubescens) and silver birch (B. pendula), Siberian fir (Abies sibirica), Scots elm (Ulmus glabra). Aspen (Populus tremula) is found in the form of single plants, as unfavorable conditions develop for it under the forest canopy. In old-growth spruce forests, the young generation of the forest has mainly a group distribution and is confined to places where overmature trees fall from the upper canopy. On average, for all trial plots, the share of small undergrowth is 64%, medium – 24% and large – 12%. On all considered trial plots, more than 80% of undergrowth is viable. The main share of doubtful and non-viable undergrowth belongs to spruce.

Authors: Alzubaidi Marwa M. , Almatrafi M. B.
Published: August 2024

Fractional partial Differential Equations (FPDEs) play an essential role in interpreting a broad variety of events in various scientific disciplines, including physics, engineering, biology, and economics. One remarkable feature of PDEs is the presence and investigation of traveling wave solutions, which are solutions that propagate with a constant speed and preserve their shape. The main purpose of this work is to obtain the traveling wave solutions of the space-time fractional Boussinesq equation using a relatively new mechanism which is the improved modified extended tanh-function approach. Fractional derivatives based on Jumarie’s modified Riemann–Liouville are utilized to deal with the fractional derivatives which appear in the fractional Boussinesq problem. Some periodic and solitary wave solutions are presented in the form of trigonometric, hyperbolic, complex, and rational functions. In addition, the effectiveness of the employed methodology is compared with the performances of other techniques such as the fractional sub-equation approach, (G’/G2)-expansion process, and the modified Kudryashov method.

Bu makale onyedinci yüzyılın ilk yarısında hazırlanmış resimli bir şiir mecmuası hakkındadır. Bugün Macar Bilimler Akademisi’nde (Perzsa Qu. 02) bulunan ve Vahşi Bafki’nin Ferhad ve Şirin, Enisi Şamlu’nun Mahmud ve Ayaz, Zülali Hvansari’nin Mahmud ve Ayaz isimli üç farklı mesnevisinden oluşan bu el yazması on altıncı yüzyıl sonu, on yedinci yüzyılın başında muhtemelen İsfahan’da yazılmıştır. Makale önce nüshanın içeriğini tanıtır, daha sonra mesnevileri metin-resim ilişkisi bağlamında inceler. Perzsa Qu. 02’de resimlerin büyük çoğunluğu Zülali’nin Mahmud ve Ayaz isimli mesnevisinde yer alır. Bir tanesi ise Enisi’nin aynı isimli eserindendir. Yaygınlıḳla açık havada meclis sahnelerinden oluşan resimler eserin lirik içeriğini yansıtır, ancak aynı zamanda metinle yakın ilişki içindedir. Zülali’nin mesnevisinde resimler neredeyse birer sayfa arayla yer alır ve arka arkaya gelen resimler metnin okuma hızını yavaşlatır, metnin lirik içeriğine odağı çeker. Bu açık hava meclislerinin çoğu birbirine benzese de, detaylara bakıldığında her birinin metinle yakın bir ilişki içinde olduğu anlaşılır. Lirik şiirlerin resimlendirilmesinde sıklıkla rastlanılan bu tür açık hava meclislerinin dışında, bu nüshada Zülali’nin metnine mahsus bazı resimler de vardır. Mesela Ayaz’ı hamamda gösteren bir resim veya şair Zülali’yi inzivada gösteren resim direk Zülali’nin metniyle alakalıdır. Benzer bir şekilde yine bir açık hava sahnesi olsa da, bu nüshada Zülali’nin metninde bahsi geçen ve Zülali’nin bir rüyasını anlatan sahnede açık havada şair Nizami’yi görürüz. Metnin lirik doğasıyla da alakalı olmakla birlikte, bu metne mahsus detayları barındıran resimler, bu nüshadaki yakın resim-metin ilişkisini gösterir. Bu mesnevilerin kompozisyonundan çok da uzun bir süre geçmeden hazırlanan bu resimli nüsha, seçki kim için hazırlandıysa bu üç mesnevinin o kişi için anlamlı olduğunu gösterir. Esere bütüncül olarak bakıldığında, muhtemelen saray dışı, ancak yüksek rütbeli bir saray görevlisi için hazırlanmış olması mümkündür. Resimler Şah I. ʿAbbas dönemi stilini andırır ve muhtemelen İsfahan’da hazırlanmıştır.

Published: August 2024

Objectives: This study aimed to assess the level of physical activity among patients with knee osteoarthritis (OA) during the COVID-19 pandemic. Methods: A total of 55 patients, aged 40 to 69 years, diagnosed with knee osteoarthritis based on the criteria set by the American College of Rheumatology (ACR) or Kellgren and Lawrence classification, were included in this study. These patients were seen at the diagnostic center of the Souss Massa University Hospital for rheumatology consultation. Pain levels were measured using the Visual Analog Scale (VAS), while knee osteoarthritis severity was evaluated using the Western Ontario McMaster University of Osteoarthritis score (WOMAC). The International Physical Activity Questionnaire (IPAQ) short version was used to assess physical activity levels. Results: The mean age of the patients was 54.6 +/- 7.2 years, with a majority of females (90.9%, n=50). The average body mass index (BMI) was 31.3 [24-39], indicating obesity in 92.3% (n=48) of the patients. The mean duration of osteoarthritis progression in the study population was 6.3 +/- 6.5 years. Radiographic analysis revealed stage II knee osteoarthritis in 38.2% (n=13) of the patients and stage III in 29.4% (n=10). No significant difference in VAS scores was observed between pre-pandemic and pandemic periods. The average WOMAC score was 52.2 +/- 18. The mean IPAQ total activity score was 1357 metabolic equivalent of task (MET)-min/week, and patients spent an average of 342 minutes per day in sedentary activities. Regarding physical activity levels during the past 7 days, 58.2% of patients engaged in moderate activity, 36.4% had low activity, and only 5.5% reported intense activity. Conclusion: Among the study participants, 52.7% of women and 5.5% of men were classified as having moderate physical activity levels. In univariate analysis, the WOMAC score was found to be the only factor significantly associated with the level of physical activity measured by the IPAQ categorical score (intense, moderate, low activity). A positive and statistically significant correlation (p<0.001) was observed, indicating that as the WOMAC score increased, physical activity levels decreased.

It includes both spoken and written forms, such as words, phrases, clauses, sentences, and paragraphs, reflecting the diverse cultures of humanity. The study of linguistics is vital for language development, with phonology, morphology, semantics, and syntax each playing a significant role. Semantics, in particular, focuses on the meanings conveyed through speech and writing, which is fundamental for effective communication. Leech (1974) describes meaning as the concept or thought transferred from a speaker to a listener through language. Instagram, a popular social media platform, enhances communication through photos, videos, and captions. Users engage actively by leaving comments, which can be either supportive or critical. This study applies Leech's theory of the seven types of meaning—conceptual, connotative, social, affective, reflective, collocative, and thematic—to examine Instagram captions. Given Instagram's widespread use, especially among college students, its features enable concise message sharing, making it an effective platform for exchanging meanings. Captions add context, express emotions, and convey situational information using various moods and illocutionary acts. This descriptive qualitative study, titled "Analysis of Semantic Meanings Found in TED Talks Instagram Captions," explores these semantic elements, enhancing our understanding of language use on social media and its impact on digital communication.

The fuel system is one of the main engine support systems which is very important in the operation of the Express Bahari 1F main engine. Operation of the main engine requires special treatment of the components of the main engine to prevent failure during operation. The Failure Mode and Effect Analysis (FMEA) method is a method that can be used to identify the priority scale in maintaining a machine by evaluating the risk of failure occurring on the machine. This research uses FMEA analysis to determine the priority scale for maintenance of the Express Bahari 1F main engine fuel system. The identification results show that the injector, fuel filter and separator components are components that must be prioritized for maintenance. This type of maintenance is carried out by checking for dirty fuel which can cause the injector to operate less than optimally, cleaning deposits on the fuel filter cartridge on the fuel filter, and replacing a new separator if the separator performs poorly. It is recommended that other components be checked so that the main engine fuel system has good reliability.

E6013 merupakan elektroda pengelasan Shield Metal Arc Welding (SMAW) yang sering digunakan dalam industri konstruksi bangunan maupun galangan kapal. Selain harganya yang murah, elektroda ini juga dapat digunakan pada segala macam posisi pengelasan serta dapat digunakan pada mesin Las AC / DC. SS400 merupakan jenis baja karbon rendah yang paling banyak digunakan dalam pembuatan konstruksi bangunan maupun kapal. Baja SS400 dituntut memiliki sifat mekanik logam yang mampu menahan tegangan pada konstruksi bangunan maupun kapal, sehingga diperlukan proses tempering pada material pengelasan untuk menghilangkan tegangan sisa dan meningkatkan keuletan material. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi suhu tempering terhadap pengelasan baja SS400. Posisi pengelasan yang digunakan dalam penelitian ini adalah 1G dengan kampuh single V-Groove. Metode penelitian yang digunakan adalah experimen. Spesimen dibagi menjadi dua kelompok yaitu kelompok kontrol dan kelompok experimen. Kelompok kontrol berisi spesimen hasil pengelasan yang tidak diberikan perlakuan tempering. Kelompok experimen berisi spesimen hasil pengelasan yang diberikan variasi suhu tempering. Hasil pengujian tarik material menunjukan peningkatan tertinggi akibat pengaruh suhu tempering sebesar 541,195 MPa pada suhu 200°C. Penurunan tertinggi kekerasan material pada suhu 350°C sebesar 165,69 HV. Tumbuhnya butiran ferrit pada struktur mikro material juga mengindikasikan semakin uletnya material hasil pengelasan setelah dilakukan proses tempering. Hasil penelitian ini dapat digunakan sebagai alternatif cara untuk meningkatkan keuletan material hasil pengelasan khususnya pada baja SS400.

Rice bran is one of the parts produced from rice milling, this part contains more than 20% dietary fiber. Rice bran has many useful substances, but its use is hampered by bran itself because it is easily damaged due to hydrolytic and oxidative activity. To overcome this problem, another method is needed so that the Bekatul can last longer. A drying machine is a machine used to reduce the air content in a substance. The aim of this research is to design the structure of a rice bran drying machine with various types of selected materials to obtain stress and cooling values. The method used in this research is finite element simulation. The materials varied in this research were AISI 304, Aluminum alloy 6061 and Galvalume Steel with thickness 0.7 mm. From the test results, it can be stated that all materials are safe to be used as the main material for making structure. However, there is one best material that produces the best maximum stress values and the smallest displacement, namely Galvalume Steel
10.30632/PJV65N4-2024a10 What Causes Mud-Logging Mud Gas Response to Vary and Two Techniques to Quantify Mud Gas
Authors:   Donovan Brothers Incorporated, Donovan William S.
Published: August 2024

Mud logging, a crucial tool for determining overpressured zones, balancing mud weight to formation pressure, and monitoring gas in formations, is hindered by the widely varying mud gas response the causes of which remain poorly understood. It’s not uncommon to observe a ten-fold variation in mud gas response while drilling formations with similar log characteristics. Furthermore, cumulative production shows a weak correlation with mud-logging mud gas response in horizontal wells. By comprehending and accounting for these mud gas variations, we can significantly enhance the effectiveness of mud logging. In the past, mud gas has been normalized using the drilling rate, hole size, and mud pump rate, yet these factors do not fully explain the mud gas response. Proper lagging of mud gas to its depth, drilling mud flushing in front of the bit, gas solubility in drilling mud, surface losses, gas trap, and sampling design will be discussed and quantified. Two innovative techniques will be introduced to quantify the gas in the formation under varying drilling parameters and conditions. These techniques, namely gas markers and normalization techniques, not only enhance overpressure detection and help determine the balanced mud weight but also provide a quantitative measure of gas in the formation. By using these techniques, mud gas can be a predictor variable in data mining applications, paving the way for enhanced well drilling performance and improved well productivity.

Reservoir fluid estimation for exploration prospects can be random and have large uncertainties. Typically, the reservoir fluid estimation in a prospect can be derived from a geochemical basin model or seismic data interpretation with regional knowledge. An analog reservoir fluid sample will often be selected for reservoir fluid estimation. Such analog samples can come from a neighboring field at some distance. The best approach for accurate reservoir fluid estimation is based on the reservoir fluid data from nearby wells when available. This paper demonstrates that mud gas data from wells inside or near the exploration prospect provides a much-improved reservoir fluid estimation. In our previous work (Yang et al., 202, 2022), we developed novel methods to estimate reservoir fluid properties from advanced and standard mud gas (SMG) data. This paper uses three field cases to illustrate how mud gas data can be translated into reliable reservoir fluid estimations for prospect evaluation for potential developments. We have SMG data available for the three field cases. The first two cases are examples of gas and oil prospect evaluations based on legacy wells without reservoir fluid samples. The last example is a prospect evaluation of overburden for potential production. The new mud gas data method provides accurate reservoir fluid estimations for three prospect evaluations with significantly reduced uncertainty. The implementation of the new method for prospect evaluation has not been reported previously. Due to the wide availability of SMG data, the new method can be broadly implemented for prospect evaluations and generates large business impacts.

The article discusses specific features of rock pressure manifestation in mine workings of the first layer in the impact zone of a geological fault and the bearing pressure from stoping operations. Factors are defined that cause the occurrence of such phenomena. The issue regarding classification of these phenomena, which are not defined in the "Guidelines for forecasting dynamic phenomena..." is stated. Specific features of the rock pressure are given depending on the structure and physical and mechanical properties of coal in different layers during slice mining of the seam. The experience of monitoring dynamic phenomena and creation of optimal methods to control the floor stability in the first layer of mine workings are described for the stoping operations in conditions of the Kuznetsk coal basin. Results of perennial instrumental survey of the rock mass using the Angel-M system with the electrometric mine equipment function applying the induced electromagnetic radiation method are described, as well as analysis of the seismic situation in the investigated area. A new term is proposed for classification of the recorded dynamic phenomena. A layout of boreholes for directional hydrofrac of the deep-buried rocks above the intermediate drift during the stoping period was designed, which allowed to effectively reduce the negative impact caused by the weight of the poorly caving rocks.
Modern approaches to control stress-strain state of rock mass using seismic data at the Tashtagol iron mine

The paper aims to describe the experience of using a modern seismic monitoring system to obtain a game-changing type of data, i.e. long-term continuous records of seismic sensor oscillations. Unlike the classical method of using seismic monitoring systems, where short segments of signal with elastic P- and S-waves are considered as valuable information, the new approach involves analyzing long-time segments that contain background oscillations of seismic sensors. The paper considers an example of obtaining such records using sensors of the GITS seismic monitoring system installed in a deep iron mine. A method of interpreting such data by means of special processing of the obtained records based on the theory of pendulum-type waves is proposed. This method can be used as a methodological basis for assessing the stress-strain state of a rock mass.
