Overthe years, Sungai Bunus has undergone hydrological changes and has become lower and narrower. Under a flood mitigation project, a flood diversion channel is proposed to reduce the volume of water in Sungai Bunusfurthermore avoid the spill over into Sungai Klang and reduce flooding events in Kuala Lumpur city. This research describes the physical modelling of the flow state of the Sungai Bunus stilling basin. Physical model was constructed to verify the design criteria of the stilling basin that will be adopted for construction. Experimental work has been carried out both with and without piers under three specified discharges (52 L/s, 86 L/s and 121 L/s) and subsequently the measurement of the water surface height profiles and point velocities through the proposed system. Consequently, there are no significant differences of outcomes between the two circumstances. The results show that there is no overflow of water at discharges of 52 L/s and 86 L/s. The water level at the Sungai Bunus section starts to flood on one side of the package when the flowrate is 121 L/s both scenarios. All test conditions with and without piers shown that the point velocity measured at the beginning of the stilling basin (inlet) is much lower than the point velocity reported near the end of the stilling basin (outlet).
‘Nobody Will Marry You If You Don’t Have a Pension’. Female Bribing Practices in Dagestan, North Caucasus
Authors: Kaliszewska Iwona , Schmidt Jagoda
Published: January 2023

Gendered dimensions of informality have been only briefly studied by anthropologists. Therefore, while engaging in the debate on informality it is important to ask how women engage in informal practices, and whether these practices are gendered. In this paper we analyse female bribing practices in the Republic of Dagestan and take a closer look at the arrangements of state welfare benefits, particularly the disability allowance and the old age pensions. How do Dagestani women engage in bribing? Why is it mostly women who ‘arrange’ state welfare benefits? What are the implications of this engagement for them? Based on case studies from fieldwork in the Republic of Dagestan carried out between 2014–2019 we show that bribing practices are gendered. We also reveal that having the resources to outsmart the state by buying benefits empowers women in a society where patriarchal arrangements are predominant. More broadly, we discuss how resistance at one level may lead to unexpected empowerment at another. By emphasizing the female perspective, this paper makes a contribution to post-Soviet area studies and anthropological studies of corruption and informality more generally.
Ungovernance and Spiritual Feudalism in Northeast Highland Georgia
Authors: Mühlfried Florian
Published: January 2023

It seems a paradox that on the one hand, the communities of northeast highland Georgia have often been represented as somewhat egalitarian in respect to their political organisation while on the other hand, their religious worlds are highly hierarchical and ordered by the principles of feudality. One very probable explanation for this seeming paradox points to the compatibility of the feudal norms with the patriarchal and clan-based social organisation of these communities. This article is the attempt to introduce another interpretation, namely that the religious system in northeast highland Georgia reflects the pain of being governed by a coercive power that is associated with the hierarchical political system of the lowland. The political system, I argue, is constructed as a counter-image of the religious system, delegating coercive power to the realm of the exceptional and tabooing its usage in the organisation of political life. In this juxtaposition, coercive power becomes internalised, albeit as a negative pole. The politics of ungovernance, in this sense, aims towards the neutralisation of coercive power, a power that people know all too well through “religious” experiences. The latter argument contradicts the dictum that anti-state societies experience coercive power as exterior.

FIVE-DIMENSIONAL ASSESSMENT MODEL FOR OPERATION AND MAINTENANCE OF STORMWATER CONTROL MEASURES - TOOL FOR STRATEGIC PLANNING AND CRISIS MANAGEMENT
Authors: Askar M. , Islam M.
Published: January 2023

Most stormwater infrastructures are aging and deteriorating in the United States. The American Society of Civil Engineers (ASCE) announced in its 2021 Report Card for America's Infrastructure that stormwater infrastructure has received a 'D' grade. The primary study objective is to help decision-makers deal effectively with the control measures of the limited-budgeted, ambiguous and inconsistently applied operation and maintenance of stormwater infrastructures. A five-dimensional assessment model for operation and maintenance of stormwater control measures (5D-SAM) was developed, including location, quality, time/quantity, cost, and environmental aspects. The model is very effective in helping decision-makers identify the current stormwater infrastructure conditions, predict the future state, manage the quantity and improve the quality of stormwater runoff in the most cost-effective manner. It helps determine whether a distressed stormwater system is beneficial to be demolished or it would be cost-effective to either repair, rehabilitate or retrofit. Moreover, the model can be utilized for fast and accurate assessment and better resource allocation for strategic planning of stormwater infrastructures.

Published: January 2023

The system of protecting territories from the harmful effects of water using vertical drainage in the zone of the North Crimean Canal of the Kherson region was considered and the proposals for its improvement by creating additional horizontal drainage systems with gravity drainage were substantiated. Field drainage studies were carried out at 8 research and production sites with a total area of 4763 hectares and a term of operation of 48-55 years and more. The conducted studies included surveying the drainage in the areas, measuring the drainage flow and the depth of groundwater levels, and determining work efficiency. The research covered the settlements: Chornyanka, Nova Mayachka, Stara Mayachka, Podo-Kalynivka, Tarasivka, Velyki Kopani, Kalanchak, and Skadovsk, for the protection of which 119 water intake wells with a depth of 26-70 m were installed. It is shown that vertical drainage is effective during the whole operation and periods of selective work when the groundwater levels were at depths of 2-3 m and 1-2 m, respectively. To ensure reliable protection of territories from waterlogging and flooding in current conditions due to the impossibility and economic impracticability of restoring the operation of all existing vertical drainage wells, it is proposed to supplement the existing protection systems based on it with systems of closed horizontal drainage of the gravity type with low-sloping and non-sloping drainage. The area of additional horizontal drainage is about 40 thousand hectares, the estimated length of the collector and drainage network is 456 km, and the depth of laying drains and collectors is 2,5-11,0 m.
WATER REGIME AND EFFICIENCY OF GROWING SUNFLOWER HYBRIDS DEPENDING ON THE ELEMENTS OF DRIP IRRIGATION TECHNOLOGY
Authors: Kaliley V. V. , Shatkovskyi A. P.
Published: January 2023

The article presents the results of experimental research on the influence of micro-irrigation system designs on the water regime, productivity, and efficiency of sunflower cultivation. Based on this, the main economic parameters of agrotechnologies of sunflower cultivation were calculated. Short-term field research was carried out in the period 2020-2022 on the lands of the Brylivske experimental field of the Institute of Water Problems and Reclamation of the National Academy of Agrarian Sciences (Kherson Region, Dry Steppe subzone). Analytical and statistical methods were used to process experimental data. The scheme of field experiments provided different options for laying irrigation pipelines of micro-irrigation systems (in the horizontal and vertical planes) and the implementation of a pulsed water supply mode (standard). The control was the variant without irrigation. According to the results of experimental studies, it was proved that the method of laying irrigation pipelines of micro-irrigation systems significantly affects the parameters of the formation of the soil water regime and the yield of sunflower hybrids in the conditions of the Dry Steppe. It has been established that the introduction of subsurface drip irrigation is more appropriate than the cultivation of sunflower hybrids, which is explained by the drought resistance of this crop. When growing sunflowers, the variant with the subsurface laying of drip irrigation pipelines provided almost identical yield parameters at lower plant water consumption coefficients.

The minimum water consumption coefficient (1077,8 m3/t) was obtained by implementing the pulse water supply mode. The highest economic parameters of agricultural technology for growing sunflower hybrids were obtained with the subsurface drip irrigation: conditionally net profit (17,11-18,17 thousand UAH/ha), lower cost (11,03-10,90 thousand UAH/ton), and also a higher level of production profitability (31,10-32,62%) (laying irrigation pipelines every 1,0 m, regardless of the sunflower hybrid). Due to the higher grain yield and specific savings of irrigation water in the pulse mode of water supply, the highest economic parameters were achieved: gross income amounted to 80,51 thousand UAH/ha, conditionally net profit – 21,24 thousand UAH/ha, cost of 1 ton of grain - UAH 10,6 thousand and the level of profitability of production – 35,8%.
DETERMINATION OF HYDRAULIC GRAIN SIZE OF NATURAL AND ARTIFICIAL SORBENTS FOR SIMULATION OF SETTLE FACILITY
Authors: Marysyk S. V.
Published: January 2023

In the conditions of progressive contamination of surface sources of water supply and inefficient wastewater treatment when using existing water treatment technologies, the research problem and the justification of the use of sorption materials for the retention of specific pollutants, in particular heavy metal ions and radionuclides, is urgent. The parameters that determine the efficiency of sorbents are indicators of their sedimentation rate. The purpose of the experiments was to determine the sedimentation rate indicators for bentonite and copper ferrocyanide, build sorbent sedimentation graphs, and establish the estimated sedimentation rate of sorbents in the sedimentation tank based on the studied data considering temperature regime. Deposition of the sorbent in settling tanks occurs with the non-stop movement of water at a low speed in the direction from the inlet to the outlet. The experiments are aimed at substantiating the efficiency and criteria of a universal facility, which is able to work equally effectively with sorbents in different aggregate states. The process of sorbent sedimentation in water is characterized by the kinetics of sorbent flakes conglomerates sedimentation. These processes are displayed in the form of deposition kinetics graphs. The experiment used powdered bentonite and a solution of copper ferrocyanide, consisting of yellow blood salt and copper sulphate in a given proportional ratio. In the course of the study the following parameters were determined: the hydraulic grain size of bentonite powdery clay, the dependence of the sedimentation rate on the temperature regime. The liquid layer was divided into layers that show changes in the amount of suspended substances depending on the depth, which made it possible to determine the dimensions of the settling tank, the height of the liquid overflow, which, in turn, made it possible to conduct simulation experiments on virtual machines with a full-scale clarifier-absorber in accordance to geometric parameters.

Published: January 2023

Aim: to study opportunity of research the evacuation function of the stomach in young people by magnetic resonance imaging with a stress drinking test. Materials and methods: the study group included 20 young people (10 men and 10 women aged 23 ± 1,12 years). At the time of the study, each test person excluded organic and functional pathologies of the gastroduodenal zone. A method of magnetic resonance imaging of the stomach with a stress drinking test (still drinking water at room temperature with a volume of 1000.0 ml) was used. The examination lasted 30 minutes, scanning was carried out every 5 minutes, a total of 7 scans. Based on the obtained three-dimensional images of the DICOM format using the HorosMobile™ application (DICOM medical image viewer), the volumes of fluid in the stomach in dynamics were calculated for each test person in the study group according to the time intervals of the scans performed by the magnetic resonance imaging machine. Systematization and data processing were carried out a Microsoft Excel. A single graph was built for the study group in the Pages graphical editor (iWork productivity suite) based on the obtained data, reflecting the reference volumes of gastric contents relative to the time scale with possible deviations from the average. Results: regardless of the type of physique and shape of the stomach in the studied subjects, the evacuation of a larger volume of fluid (81,53-82,54%) occurred by the 15th minute of the study. Complete evacuation of gastric contents occurs between 25 and 30 minutes of the study. Conclusions: the results obtained by MRI studies of the stomach with a stress drinking test give an idea of the options for normal physiological evacuation of gastric contents in young people, in the absence of organic and functional pathology of the gastroduodenal zone.

Aim. To compare the long-term outcomes and qualitive of life (QOL) of robot-assisted fundoplication (RAF) and laparoscopic fundoplication (LF) in patients with cardiofundal and subtotal hiatal hernias (HH). Materials and methods. The study included 62 patients with HH, who underwent antireflux surgery in the clinic of Faculty Surgery No. 1 of Sechenov University in the period from January 2015 to February 2021. The main group included 32 patients who underwent robot-assisted fundoplication (RAF) according to A. F. Chernousov, the comparison group included 30 patients who underwent laparoscopic fundoplication (LF). Complaints of the patient, X-ray, endoscopic studies, PH-impedance-metry in the long-term period were evaluated. To assess the quality of life, the questionnaires SF 36 (The Short Form-36) and GERD-HRQL (Health-Related Quality of Life in Patients with Gastroesophageal Reflex Disease) were used. Results. Periodic heartburn in the long-term period was noted by 2 (6%) patients of the RAF group and 4 (13%) in the LF group. Endoscopic signs of mild esophagitis were detected in 1 (3%) patient from each group. X-ray in 9 (28%) patients of the RAF group and 11 (37%) patients of the LF group showed migration of the esophageal-gastric junction above the diaphragm level with complete preservation of the antireflux function of the fundoplication cuff. The QOL indicators of the SF 36 questionnaire did not differ in both groups and were comparable to the population of “conditionally healthy” people. The indicators of the GERD-HRQL questionnaire were better in the RAF group, but the differences had no statistical significance (RAF - 2.53 ± 5.1 points versus LF - 5.23 ± 9.4 points, p-value = 0.321). Conclusion. RAF and LF in the modification of A. F. Chernousov are equally effective in the treatment of RE and GPOD in the long-term period and provide good indicators of quality of life that do not differ statistically from each other.

Published: January 2023

The authors consider diseases of internal organs as a reflection of the influence of various factors on the human exposome (as a complex symbiotic system) in the process of formation of the noosphere from the biosphere. At the same time, various exposome factors caused deep violations of the evolutionarily developed symbiotic relationships of a person with the environment and the internal environment with a violation of the basic systems of regulation and adaptation with the development of metabolic imbalance and the subsequent formation of various diseases. The important role of connective tissue in these processes, its various elements in the regulation of the structure of organs and cells, the near-cellular space, metabolism, immunity, ways of interaction with the microbiota and its network structures, decentralized forms of homeostasis regulation are considered.

Despite significant advances in the diagnosis of tuberculosis, the issues of the mechanism of development and treatment of fibrotic manifestations are relevant and take place in the treatment. The aim of the study was to study the content of perlecane and to find out its participation in the remodeling of the extracellular matrix of the organs of mice with tuberculous inflammation and when they were injected with an antitubercular composition. Materials and methods. The experiment was carried out on male mice of the BALB/c line, which were divided into 4 groups of 5 individuals each. All animals, with the exception of intact mice (group 1), were retroorbitally injected with BCG vaccine once (0.5 mg of microbial bodies in 0.2 ml of 0.9% NaCl solution) to simulate a generalized tuberculosis process. After infection 6 mo for 3 mo, group 2 mice were intraperitoneally injected with 50 µl of 0.9% NaCl solution, group 3 - intraperitoneally with 50 µl of liposome-encapsulated dextrazide solution (LEDZ, isoniazid conjugate and oxidized dextran enclosed in liposomes), group 4 - LEDZ solution was inhaled by spraying in the chamber through a nebulizer for 5 min at the rate of 50 µl of solution per animal. After the last administration of the NaCl and LEDZ solution, mice were removed from the experiment, organs were taken, and tissue homogenates were prepared. The content of perlecane, hyaluronan, protein-bound hydroxyproline, tissue metalloproteinase inhibitors (TIMP-1, TIMP-2) and the activity of matrix metalloproteinases (MMP), hyaluronidases, α2-macroglobulin were measured. Results. In all organs of infected mice, the content of perlecan, hyaluronan, protein-bound hydroxyproline, TIMP-1, TIMP-2 was increased, MMP, hyaluronidase, α2-macroglobulin were activated. Regardless of the method of administration of LEDZ, the severity of fibrosis decreased due to a decrease in the content of hyaluronan in all organs and protein-bound hydroxyproline in the lungs. Perlecan with intraperitoneal administration is involved in fibrosis of the spleen, inhalation - reflects the severity of liver fibrosis. Conclusion. Correlations of perlecan with extracellular matrix components reflect participation in the regulation of fibrosis of organs in BCG-induced inflammation.

Lesions of the digestive system in diabetes mellitus (DM) are of secondary nature and arise due to autonomic neuropathy. As a result of hyperglycemia, lesions of the esophagus, stomach, small and large intestine develop. The most common disorder of the digestive system in diabetes is gastroparesis. The diagnosis of gastroparesis is currently insufficient. It is connected with low awareness and, as a consequence, rare visit of patients to specialists, and also with similarity of clinical symptoms with other functional disorders of gastrointestinal tract (GIT). The main risk factors for gastroparesis are hyperglycemia, smoking, alcohol, and certain medications. Most patients with gastroparesis suffer from depression and increased anxiety. Taking medications to treat depression negatively affects the function of the digestive system. This problem interferes with patients’ quality of life. During the pandemic of coronavirus infection, the number of patients seeking medical care due to exacerbation of gastrointestinal disorders increased. The question of etiology is subject to further study. This review also considers the effect of cholecystectomy on the development of gastroparesis in these patients. These patients need special monitoring of glucose levels to prescribe timely antidiabetic therapy and prevent future gastroparesis. For the treatment of lesions of the digestive system in diabetes mellitus, a special diet, in particular the exclusion of hard-to-digest fiber, fatty foods, inclusion of vitamin complexes and normalization of the microbiota plays a paramount role. The main therapeutic value is the timely diagnosis and normalization of glucose levels.

The article presents data on post-covid disorders of internal organs and systems with an emphasis on involvement in the pathological process of the gastrointestinal tract. The authors showed a high frequency of grastroenterological changes detected endoscopically: GERD of varying degrees of manifestation - 63%, inflammatory changes in the stomach (superficial, atrophic, hemorrhagic, erosive gastritis) - in 46%, damage to the duodenum and jejunum - in 12% and inflammatory changes in the ileum - 9% in the form of hemorrhages of varying degrees of prescription against the background of edematous pastous hyperemic folds, of which 4% had single or multiple erosions up to 3 mm, located in different parts of the small intestine, and 20% had lymphangiectasia of varying severity (in 4% of them in the form of “confluent fields” over several segments of the small intestine), epithelial formations of the upper gastrointestinal tract (hyperplasia, early cancer, GIST, neuroendocrine formations) - in 11%, inflammatory diseases of the colon (CD, UC) - in 4%, epithelial formations of the colon - 17%, diverticula of the colon - 8%. In 3 patients, solitary colon ulcers were found, located in the sigmoid and rectum. The effectiveness of the inclusion in the complex therapy of the recombinant interferon alfa 2-b in combination with vitamins E and C of post-covid changes in the gastrointestinal mucosa, especially solitary ulcers, has been shown

Introduction. Clinical manifestations of inflammatory bowel diseases (IBD) are limited not only by the gastrointestinal tract syndromes, but also by a wide range of extra-intestinal manifestations, which include skin manifestations. Skin lesions in IBD occur in different forms. Some of them are associated with the activity of the main process, for example, gangrenous pyoderma. Others, such as psoriasis, are combined with pathogenetic factors common to IBD. Materials and methods. Three clinical observations of patients with IBD and extra-intestinal manifestations are presented: gangrenous pyoderma (case 1) and psoriasis (cases 2, 3). The stages of differential diagnostic search and treatment are described. The interleukin 12/23 inhibitor ustekinumab is prescribed to both bionaive patients (observations 1, 2), and to the patient who (observation 3) had high activity of the inflammatory process in the intestine and had received early treatment with GEBD. The extension of indications for use ustekinumab (ulcerative colitis, Crohn’s disease, psoriasis, psoriatic arthritis) of allows for its wider use in the treatment of patients. Conclusion. The interleukin 12/23 inhibitor ustekinumab has broad indications for use; its use allows to achieve a positive clinical, laboratory and endoscopic effect at the early stages of use. This effect has spread to skin manifestations, the reduction of which occurs in parallel with the healing of the intestinal mucosa.

Acute appendicitis is still the most common surgical disease in the experience of surgeon and it requires operative treatment in hospital. There are several suggestions on the causes of acute appendicitis: infectious or neurovascular conditions, obturation of the orifice of vermiform appendix with a fecal bolus, and other versions. One of the rare causes of acute appendicitis is ischemia of vermiform appendix, which results in the development of primary gangrenous appendicitis. The clinical manifestation of this pathology may be atypical. We present a case report of a 65-year-old patient with acute gangrenous appendicitis complicated by localized purulent peritonitis. When admitted to the hospital, the patient was suspected of mesenteric thrombosis. MSCT angiography was performed about that, which diagnosed thrombosis of a. appendicularis and acute appendicitis. Treatment included laparotomy, appendectomy, sanitation, and abdominal drainage. In the paper, we discuss the incidence and results of treatment of acute appendicitis.

The review presents up-to-date information on the pathogenesis of disorders of the intestinal microbiotope and the relationship of these disorders with the use of medications traditionally prescribed in treatment regimens for various diseases, presents the main aspects of drug-microbial interactions, highlights the issues of correction of iatrogenic intestinal dysbiosis. One of the main exogenous factors in the development of intestinal dysbiosis at the present time, of course, can be considered drug therapy. The extremely widespread and often uncontrolled use of antibacterial drugs, nonsteroidal anti-inflammatory drugs, laxatives, drugs for the correction of carbohydrate metabolism, proton pump inhibitors, glucocorticosteroids, antidepressants, cytostatic drugs to a greater or lesser extent has a negative effect on the human microbiotope. On the one hand, the microbiota is a drug target, on the other hand, the gut microbiota itself can have both direct and indirect effects on the metabolism of drugs. The potential of the influence of microorganisms on the absorption, distribution, and metabolism of drugs deserves increased attention and detailed study. At the same time, the issues of prevention and correction of intestinal microbiota disorders against the background of taking various medications deserve even more attention from doctors of various profiles with the mandatory inclusion of drugs that harmonize the intestinal microbiotope in the treatment regimens of the underlying disease.
