    No full text
    The goal of this water treatment study was to evaluate the effects of ozonated water and ultraviolet light (100–280 nm) on the efficacy of Bacillus subtilis spores. These water treatments are based on the current research for sanitizing bio-contaminated water. However, this study focused on small-scale water treatment units that could be modified or custom-built for a mobile sanitation system used for cleaning field equipment. The factorial study included four factors, resulting in a total of 16 water treatments. The ultraviolet light water treatment (UVC + UVC), with a total exposure time of 60 minutes, resulted in a log10 reduction of 3.51, equivalent to a 99.9% reduction in viable spores. The average spore reduction from UVC treatment increases with exposure time, then reaches an asymptotic plateau between 30 and 60 minutes. The combination of ozonated water with UV radiation yielded promising results in reducing spores. Wastewater technology, based on UVC systems, may be implemented with both mobile power washing systems. Additionally, larger units are required to effectively sterilize bio-contaminated wastewater within farms and storage facilities in the agricultural industry

    No full text
    Inequalities involving fractional operators have also been an active area of research. These inequalities play a crucial role in establishing bounds, estimates, and stability conditions for solutions to fractional integrals. In this paper, firstly we establish these new identities for the case of twice differentiable functions and Caputo-Fabrizio fractional integrals. By utilizing these new identities, novel inequalities are obtained for trigonometric convex functions, and exponential trigonometric convex functions and exponential trigonometric convex functions. It is expected that the outcomes of this research will point to new developments in the study of fractional calculus

    The study has been conducted at the Education-Scientific Institute of Natural and Agrarian Sciences of Lugansk National University named Taras Shevchenko (Ukraine). The research was aimed at establishing the elements of agricultural technology that ensure the maximum yield of pure seeds of sterile analog of the maternal lines GE6A and GE57A when grown under group isolators. This study examined the structure of plant productivity of sterile analog when grown under group isolators with a width of row spacing of 70 and 45 cm, with a plant population of 40, 50, 60, and 70 thousand plants ha-1. The created conditions for growing plants under group isolators had different effects on the development of the vegetative mass of plants and quantitative characteristics of the productivity of plants of lines. A width of row spacing and crop density statistically influenced (P < 0.05) the formation of quantitative traits of plant productivity of maternal lines. Growing lines with a width row spacing of 45 cm at a plant density of 40-60 thousand ha-1 ensured an increase in the weight of head seeds in the sterile analog of the maternal line GE6A by 3.7-5.8 g, in the sterile analog of the maternal line GE57A - by 4.2-6.2 g. Each maternal line had an individual reaction to changes in growing conditions. A width of row spacing of 45 cm and a sowing density of 50 thousand plants/ha ensured the highest pure yield of seeds from a sieve with a hole size of 2.5 × 20 mm from one isolators of 16.0 kg and a maximum yield of 1.69 t ha-1 for the sterile analog of the maternal line GE6A. A width of row spacing of 45 cm and a sowing density of 50-60 thousand plants/ha ensured the highest pure yield of seeds from a sieve with a hole size of 2.5 × 20 mm from one isolators of 14.7-14.8 kg and a maximum yield of 1.55-1.57 t ha-1 for the sterile analog of the maternal line GE57A. The sterile analog of the maternal line GE6A, with a maximum yield level at a width of row spacing of 45 cm, produced a higher yield of 0.14-0.12 t ha-1 than the sterile analog of the maternal line GE57A. The research results allowed us to recommend the use of agricultural technology elements individually when growing maternal lines under group isolators

    Reliable data on radio propagation is required to suggest useful models for radio-climatic study. Computation of some secondary radio parameters across ten locations in Nigeria was done to deduce their effects on Line-of-Sight links. ERA-5 data obtained from the archive of European Centre for Medium-Range Weather Forecast (ECMWF) comprising of surface air and dew temperature, atmospheric pressure and relative humidity covering eight years (January 2010 – December 2017) was utilized. The results show that average radio refractivity values during the wet season (343.4 N-units) was higher than the dry season (273 N-units) and radio refractivity gradient values increase as the wet season progresses. Mean effective earth radius factor (k-factor) for the period of study were 1.38, 1.34, 1.67 and 1.72 for the rainforest, mangrove swamp, Sudan and guinea savannah regions respectively. It was also observed that a distinct relationship exists between the geo-climatic factor (K) and the seasons of the year with a range of 2.2 ×10-5 to 1.0 ×10-4

    Soft Intersection Quasi-interior Ideals of Semigroups

    No full text
    It has been shown that generalizing the ideals of an algebraic structure is both interesting and beneficial for mathematicians. In this context, the concept of quasi-interior (Ԛꟾ) ideal was introduced as a generalization of quasi-ideal and interior ideal of a semigroup. In this paper, we apply this concept to soft set theory and semigroups, introducing a new form of soft intersection (S-int) ideal called the "soft intersection (S-int) quasi-interior (Ԛꟾ) ideal." The main objective of this study is to investigate the relationships between S-int Ԛꟾ ideals and other specific types of S-int ideals in a semigroup. It has been shown that every S-int interior ideal of a semigroup is an S-int Ԛꟾ ideal, and every S-int ideal is an S-int Ԛꟾ ideal. The S-int bi-ideal of a group is an S-int Ԛꟾ ideal, the S-int quasi-ideal of a regular group is an S-int Ԛꟾ ideal, the idempotent S-int Ԛꟾ ideal is an S-int bi-quasi-ideal and an S-int bi-interior ideal. Counterexamples are provided to show that the opposites of these statements are not always valid. We prove that for the converses to hold, the semigroup should be a group or regular, or the S-int Ԛꟾ ideal should be idempotent. Our main theorem, which demonstrates that if a subsemigroup of a semigroup is a Ԛꟾ ideal, then its soft characteristic function is an S-int Ԛꟾ ideal, and vice versa, enables us to establish a connection between semigroup theory and soft set theory. Through this theorem, we illustrate how this concept connects to the existing algebraic structures in classical semigroup theory. Additionally, we offer conceptual characterizations and an analysis of the concept in terms of soft set operations, including soft image and soft inverse image, supporting our claims with specific, informative examples. Furthermore, the connection between a regular semigroup and the structure of S-int Ԛꟾ ideals is established and presented

    Full text link
    Turboprop aircraft may face a variety of harsh flight environments during flight, and various foreign objects may be sucked into the engine, among which the inhalation of sand can lead to erosion of the blades of the compressor. Such ingestion often results in compressor blade erosion, which can lead to engine surge and power loss. Therefore, this study explores the aerodynamic and sand separation characteristics of the inlet channel with a bypass channel through numerical simulation methods. ANSYS Fluent software is used to simulate the six-bladed propeller rotation based on the slip-grid technique by combining the unsteady Reynolds-averaged Navier-Stokes equations (URANS) and shear stress transport (SST) turbulence model. A Lagrangian discrete phase model (DPM) is applied to track the motion of standard coarse sand. The focus is on analyzing the mechanism of different propeller speeds and scavenge ratio (SCR) on the separation efficiency (η)

    Anxiety disorders are conditions characterized by heightened responses to perceived threats, resulting in symptoms that negatively affect everyday life. This study investigates the anxiolytic effect of a natural chalcone isolated from Croton anisodontus Müll.Arg. focusing on its modulation of anxiolytic activity in modulating anxiolytic activity via GABAergic and serotonergic neurotransmission in an adult zebrafish model. The acute toxicity of the chalcone was assessed during a 96-hour period, and the anxiolytic behavior of fish treated with chalcone was evaluated using light/dark tests and open field tests (n=6 animals per group). Chalcone showed no signs of toxicity for up to 96 hours of analysis. The results demonstrated a significant anxiolytic effect of the synthesized chalcone, suggesting its therapeutic potential in treating anxiety. Furthermore, the findings indicate that this anxiolytic effect is mediated by serotonergic and non-GABAergic neurotransmitter systems. From molecular docking simulations, it was possible to estimate that the 5-HT3A receptor (5-HT3AR) pathway is the most likely target way for the chalcone to act. MPO-based ADME predictions indicate that the chalcone exhibits high cellular permeability suggest that chalcone has a high cellular permeability and can distribute better in biological tissues than in blood plasma, supporting its potential to act in the CNS by crossing the blood-brain barrier. These findings enhance the understanding of contribute to understanding of chalcone\u27s mechanisms of action and provide a solid basis for future studies aimed at developing new therapeutic strategies to develop new therapeutic approaches for anxiety disorders

    Lipids play diverse roles in sustaining life, including energy storage, hormonal balance, and cellular communication. Alterations in lipid metabolism can lead to various disorders, including diabetes, atherosclerosis, cancer, and neurodegenerative diseases. Among these disorders, lysosomal storage disorders (LSDs) related to glycosphingolipids metabolism present significant challenges. This review systematically analyzes the current literature on LSDs, focusing on classification, clinical presentations, diagnostic advancements, available treatments, and emerging therapeutic strategies. Glycosphingolipids biosynthesis, particularly its role in viral dissemination and melanin synthesis, underscores its significance in health and disease. Additionally, the review delves into specific LSDs, such as Fabry disease, Gaucher disease, Sandhoff disease, Tay-Sachs disease, and Krabbe disease, highlighting their pathophysiology, prevalence, and treatment options. Enzyme replacement therapy and hematopoietic stem cell transplantation are mainstays in LSD treatment, but gene therapy shows promise. Furthermore, the review explores the role of glycosphingolipids in non-communicable diseases like diabetes, cancer, atherosclerosis, lupus, Alzheimer\u27s, Parkinson\u27s disease, and influenza. Understanding glycosphingolipid metabolism offers insights into disease mechanisms and therapeutic targets, paving the way for improved treatments and ultimately enhancing patient outcomes

    Kilka Fish is classified in the fatty fish group and is more perishable than other aquatics. It is very sensitive to oxidation during cold storage. Fat oxidation reduces the quality of Kilka, a decrease in shelf life and economic losses. Because it leads to color change (yellow) of Kilka. Therefore, the present study aimed to evaluate the effects of sodium alginate and whey protein coating on the prevention of fat oxidation of Kilka fillets during 12 days of refrigerated storage. Whey protein 15% and sodium alginate 1% were used at time= 5 min. Uncovered samples were considered as controls. Humidity, peroxide, FFA, TBA, pH, and fat were not significant in the samples covered with whey protein (73.62%, 0.08 meq kg oil-1, 1.01 g 100-1, 0.06 mg kg-1, 6.37 and 4.45%) compared with those covered by sodium alginate (73.91%, 0.05 meq kgoil-1, 1.09 g 100-1, 0.01 mg kg-1, 6.49, and 4.00%) (P>0.05). However, the index chemicals were lower in these samples compared with the control (59.16%, 3.07 meq kgoil-1, 5.73 g 100-1, 2.14 mg kg-1, 6.81 and 3.99%. Unlike fat, the other chemical tests were significant between control and covered samples (p<0.05). Covered samples had good quality at the end of the storage period. However, the control samples lost their quality after 6 days. Fish soaked with sodium alginate had better quality compared with the other samples. The use of sodium alginate is recommended by the seafood processing industry to maintain the quality of kilka during refrigeration
