AbstractThe rupture degree is one the most important vulnerability parameter in networks which are modelled by graphs. LetG(V(G),E(G)) be a simple undirected graph. The rupture degree is defined byr(G) = max{w(G–S)–|S |–m(G–S):S ⊂ V(G) andw(G–S)>1}where m(G–S) is the order of a largest connected component inG–Sandw(G–S) is the number of components ofG–S, respectively. In this paper, we consider the vertex contraction method based on the network agglomeration operation for each vertex ofG. Then, we have presented two graph vulnerability parameters called byagglomeration rupture degreeandaverage lower agglomeration rupture degree. Furthermore, the exact values of them for some graph families are given. Finally, we proposed a polynomial time heuristic algorithm to obtain the values ofagglomeration rupture degreeandaverage

Published: August 2023

AbstractHepatic steatosis is a frequent pathological finding in patients with chronic viral C infection (HCV) and can be independently associated with increased alcohol consumption, type 2 diabetes, obesity and hyperlipidemia. All these factors can lead to the development of hepatic steatosis in patients with HCV. There are several noninvasive techniques and scores used for diagnosing and quantifying liver steatosis. Successful eradication of HCV with interferon-free treatment regimens has been suggested to improve the level of hepatic steatosis. The precise mechanisms responsible for these beneficial effects are currently under investigation, but it is thought that the decrease in hepatic inflammation and viral replication contribute to the resolution of hepatic steatosis. Moreover, the overall enhancement in liver health and metabolic factors may also have a significant impact.

Abstract
We present the case of a young patient, known to have COPD and DZ, who presented to the emergency room for dyspnea and sudden onset right laterobasal pain. From the patient's recent history we note episode of right total pneumothorax five days prior to presentation to our unit, for which pleural drainage was fitted. Clinical examination and standard chest X-ray performed in the emergency department established the diagnosis of recurrent total pneumothorax. Given the medical history and recent history of pneumothorax in a young heavy smoker patient with two episodes of right pneumothorax, one of which was recent, known with diabetes mellitus and COPD, with imaging changes such as "reticulo-nodular lesions with cystic appearance and interstitial fibrosis on the left lung area", the diagnosis of COPD was questioned and the suspicion of pulmonary histiocytosis X was raised, which is why, together with the radiologist and thoracic surgeon, the decision was made to perform a surgical treatment and a lung biopsy to establish a definite diagnosis. The result of the lung biopsy confirmed the suspicion of pulmonary histiocytosis X.
Since in histiocytosis X the damage is multi-organ, one month postoperatively the patient underwent a complex biological, functional and imaging evaluation to identify or exclude other affected organs. Imaging and functional investigations performed, collaborated with the patient's history, age and medical history refuted the diagnosis of COPD. Therapeutically for pulmonary histiocytosis X it was recommended to stop smoking urgently and monitor respiratory function at 6 months in the first year after diagnosis.

AbstractThe article presents a hydraulic hydrogen compression solution designed to serve as a booster compressor. It can be adapted to changing parameters of the inlet pressure of hydrogen and allows stabilising the hydrogen accumulation process in the high-pressure storage.The main results of this study were obtained using a numerical model developed to explore the thermodynamic processes that occur during the hydraulic compression of hydrogen. The modelling was carried out using COMSOL Multiphysics® 6.0 software with the CFD and heat transfer modules. The compression chamber in the form of a cylinder with a volume of 1.14land wall thickness of 5 mm was used in the computational model. The aim of these simulations was to investigate the temperature change limits of hydrogen, cylinder walls and working fluid, as well as to estimate the actual value of pressure inside the cylinder. The considered process of pressure increase in the cylinder chamber was modelled as a continuous change of volume filled with working fluid with discrete time step of 0.01s, taking into account the increase of temperature inside the cylinder. The derived modelling results for different durations of compression stroke tsfrom 0.5 to 20.0swere presented. The curves of energy consumption and temperature rise during the compression process were calculated for initial hydrogen pressures P1= 3.0, 10.0, 15.0 and 20.0MPaand compression ratio Kc = 5.0.The results of simulation of thermodynamic processes and their analysis allowed estimating energy consumption in the system of hydraulic compression and determining conditions which would lead to the increase in efficiency of hydrogen compression operation systems under consideration.

Published: August 2023

AbstractThe present paper provides the dependence of the temperature change on time and the depth of the soil massif based on numerical calculations. Mathematical modelling of the one-dimensional soil temperature field via an algorithm and a PC program is carried out without taking into account the influence of the phase transition of moisture in the soil pores during seasonal freezing and thawing using the finite difference method. The amplitude of fluctuations in the temperature regime is obtained as that decreases with depth from the soil surface. It is established that over time heat spreads from the pipeline to the surface of the soil, and over time more intense heating occurs both near the pipeline and in the body of the soil massif.

Soil-Transmitted Helminths (geo-helminths) are intestinal parasites causing human infections that are soil-borne. The study assessed the level of soil contamination with geo-helminths ova and also evaluated the level of compliance to WASH policies in some selected public and private schools in Akure North and Owo Local Government Areas of Ondo state, respectively. The study was conducted in the major districts of the two towns.
Methods
Soil samples were collected from three (3) different locations within each school premise: Toilet areas, classroom and playground. Assessment sheets were used to evaluate data on indicators of compliance to WASH interventions. Modified Baemann’s culture technique was used in the extraction of geo-helminths larvae and sedimentation techniques were used in the concentration and isolation of geo-helminths eggs. The significant difference in soil contamination between public and private schools was obtained using statistical analysis.
Result
Of the 162 soil samples examined from each local government area, Akure North had the highest number of contaminated samples, n=116 (71.61%), while Owo local government had the least, n =88 (54.32%). Four (4) different geo-helminth species were identified; Hookworm, Ascaris lumbricoides, Strongyloides stercoralis, and Trichuris trichiura. The most occurring parasites seen in Akure North were hookworm larvae (67.83%), Strongyloides stercoralis (67.83%), hookworm ova (11.25%) and ova of Ascaris lumbricoides (7.56%). Likewise, Hookworm larvae had the highest level of occurrence (51.67%), while Trichuris trichiura was the least occurring (0.77%) in Owo local government area. Public schools had the higher parasite count 668/780 (85.64%), while private schools had the lesser parasite count, 112 /780 (14.36%).
Conclusion
The study revealed poor deployment of WASH in the schools, and children were predisposed to geo-helminths infections due to the high level of contamination, particularly in the public schools.

Authors: Alex, Gicheru  , Patrick Ngugi  
Published: August 2023

Manufacturing companies in Kenya have been experiencing problems in the performance of their production and operations management. Stock-outs result from holding too little stock of the offending lines because the forecasts and material requirement planning controls are inadequate. High stock levels arise because too much stock has been purchased through bad forecasting, monitoring or controls. The aim of this research was to investigate the effect of e-inventory management on the performance of food and beverage manufacturing firms in Kenya. The study had specific objectives, which were to determine the influence of material requirement planning and radio frequency identification on the performance of these firms. The research design used was descriptive, and the target population was individuals employed in food and beverage firms in Kenya. A stratified random sampling method was employed due to the heterogeneous nature of the population. Structured research data was collected and analyzed using descriptive and multiple regression analysis.
The study found that radio frequency identification had the second highest impact on the performance of food and beverage firms in Kenya, with a β value of 0.295 and a P-value of 0.004. Additionally, material requirement planning technology had the greatest influence on the performance of food and beverage firms in Kenya, with a β value of 0.316 and a P-value of 0.006. Based on these results, it can be concluded that food and beverage firms in Kenya should prioritize the use of radio frequency identification technology for better operational efficiency and performance. The study also recommends that management should focus on accurately forecasting inventory demands and providing inventory management training for employees.

The study evaluated the influence of variety and temperature on the retention of nutrient antioxidants, vitamins A and E of Abotem, Aborohema, Omankwa, Abeleehi and Dorke SR varieties of maize. The exact retentions (mg/100mg) were computed using the yield expressed as a ratio of the absorbances dilution factor to the weight of the sample. The loss of vitamin A contents as the temperature increased from 30˚C to 60˚C was found to differ in the order Omankwa (2.759mg/100mg)>Aborohema (2.679mg/100mg)>Abotem (1.665mg/100mg)>Dorke SR (0.996mg/100mg) >Abeleehi (0.865 mg/100mg). Better retention of vitamin A occurred at the soaking temperature of 30˚C. In contrast, better retention of vitamin E was achieved at the soaking temperature of 60oC. The increase in vitamin E contents were in the order Abotem (1.984mg/100mg)>Aborohema 1.886mg/100mg) > Abeleehi (0.973mg/100mg)>Omankwa (.941mg/100mg)>Dorke SR (0.2283mg/100mg). Soaking caused changes to the quantities of vitamins A and E retained after soaking, but the changes were influenced by variety and soaking temperature. The change in vitamin A content of soaked maize within the temperature range of 30˚C - 60˚C followed a zero-order kinetics reaction equation, with a regression coefficient of the kinetic model between 0.95 and 0.99.

Подтопления и наводнения в городах ежегодно наносят миллиардный ущерб городской инфраструктуре и представляют собой угрозу населению и их имуществу. Традиционные инженерные решения по управлению стоком в современных условиях становятся неэффективными и нерентабельными. Одним из вариантов решения проблемы избыточного стока в городах является создание водно-зеленой инфраструктуры. Проведенное в работе исследование показало, что в городе Вологда существуют риски подтопления территории и интерес жителей и администрации к поиску путей решения данной проблемы. Было выявлено, что существующая водно-зеленая инфраструктура изучаемой территории недостаточно развита и не справляется со стоком во время выпадения интенсивных осадков. Учитывая климатические особенности, особенности рельефа и состояние существующей растительности был осуществлен подбор оптимального сочетания элементов водно-зеленой инфраструктуры и ассортимент растений для изучаемой территории.
Flooding causes annual billions of dollars of damage to urban infrastructure and pose a threat to the population and their property. Traditional engineering solutions for flow management currently are becoming inefficient and unprofitable. One of the ways to solve the problem of excess runoff in cities is to introduce a blue-green infrastructure. The study conducted showed that in the city of Vologda there are risks of flooding and there is an interest of residents and the authorities in finding ways to solve this problem. It was revealed that the existing water-green infrastructure of the studied territory is insufficiently developed and cannot cope with runoff during heavy precipitation. Taking into account climatic features, terrain features and the state of existing vegetation, the selection of the optimal combination of elements of bluer-green infrastructure and the assortment of plants for the studied territory was carried out.
