Published: January 2023

Abstract
The study assessed the physico-chemical characteristics of sediments from Owella reservoir in Osun State, Nigeria with the primary aim of creating a baseline information in aspect of limnology and also to further assess influenced by anthropogenic activities as well as characteristics that were affected mostly by natural sources in the water body. Twenty sampling stations were established along the reservoir representing its three different sections and two zones for a period of two years. On the average, the reservoir sediment was mostly sand, clayey-sand in texture, acidic in chemical reaction, low in nutrients and moderate in organic matter. Although, nutrients were identified to be mostly of anthropogenic origin, while alkali metals and alkaline earth metals were from both anthropogenic and natural sources. The overall order of dominance of the exchangeable cations was: Mg2+ > Ca2+ > H+ > Al3+ > K+ >Na+ and anions in the order PO34- > SO42− > NO3−> Cl−. Significantly difference (p < 0.05) were observed in the physico-chemical characteristics of the sediment across the two zones (littoral and open water) of the reservoir and horizontal variation along the three basin sections (upstream, mid-basin and downstream) and over the two seasons of the year were mostly not significant (p > 0.05). The overall mean values obtained for particle size distribution along the reservoir were in the following order: sand (7.31%) > Silt (43%) > clay (57%). Surface run-offs are major contaminant in Nigeria waterbodies and through geochemical weathering of the top soils. The results showed low concentration of cations, anions and nutrients compound in the sediment of Owella reservoir which suggests low influence of anthropogenic activities on the sediment quality.

Abstract

Context
Here we develop a practical framework (Mosaico) and report a real-world example of early implementation of a Fire-Smart Territory (FST) in Sierra de Gata-Las Hurdes region of central Spain.
Objectives
We aimed to assess the impact of landscape changes induced by local land managers (indirect prevention) on simulated fire spread under different governance scenarios developed in 2016-2021.
Methods
Following a participatory process in the region, we received 250 proposals for intervention (49.6% from agriculturalists, 22.8% from forest producers -mainly resin tappers-, and 27.6% from shepherds). From the 94 (37.6%) proposals implemented by the end of the study, we quantified changes in fuel models over the whole territory (Scenario 1, S1). Then, we simulated fires in 20 ignition points to estimate area burned in S1 and three other governance scenarios.
Results
To date, the sole intervention of LLMs results in a low to moderate impact (current mean: 10.5; median: 1.8), which can be explained by the high frequency of small-scale interventions (agriculture) and the modest impact on fuel reduction of large-scale interventions (livestock grazing). A combination of LLM and public actions is needed to reach a more substantial reduction of burned area (S2-S3, mean % impact:14.1-18.9; median: 6.9-10.8). Relaxing legal/administrative constraints to allow large private intervention would result in the greatest attainable impact on burned area (S4, mean: 25.0; median: 17.8). Adaptive management of Mosaico approach must be focussed on improving LLM capacity to modify larger portions of the territory and prioritizing critical areas such as fire propagation nodes.

Abstract

The Classical Fourier's theory of heat flux is well-known in continuum physics and thermal sciences. However, the primary inconvenience of this law is that it contradicts the principle of causality. To investigate the thermal relaxation time characteristic, Cattaneo–Christov theory is assumed thermally. In this regard, the characteristics of magnetohydrodynamic (MHD) mixed convective flows of Casson nanofluids between two fixed impermeable parallel plates are revealed analytically and numerically. the resulting system of partial differential equations is changed via practical transformations into nonlinear ordinary differential equations. An advanced numerical algorithm is utilised in this study to get higher approximations for velocity and temperature fields, in addition to their corresponding wall gradients. For validating our numerical code, the current outcomes are compared with the other methods utilized in this work Akbari Ganji Method and Homotopy Perturbation Method. Moreover, it is revealed that the velocity field decreases for large values of casson and magnetic parametre. we can also see that Casson nanofluid is accelerated in case of lower yield strength. Larger values of thermal relaxation parameters create a lessening trend in the temperature distribution. The results of this study can help engineers improve, and researchers can conduct research faster and easier on this type of problem. also This work helps researchers to master the theoretical calculation of this type of problem.

Published: January 2023

Abstract
Employing qualitative information from three diverse rural Indian cooking fuels, this paper abstracts the various initiatives to adopt clean cooking fuel. Due to India's rapid economic growth, the need for cooking energy, particularly gaseous fuel, has exponentially increased yearly. The two main supporting pillars of India's current energy strategy are fossil fuels and natural gas. The exploitation of fossil fuels impacts the ecology. Moreover, It might be challenging to decide whether to implement new technology due to low acceptance rates or widespread resistance in the Indian rural clean cooking approach. In this context rudimentary analysis has been performed to comprehend the variables influencing the adoption of clean cooking fuel in the Indian rural community. Various SWOT factors have been outlined through literature and stakeholders survey. In addition, fuzzy-TOPSIS analysis has been done to rank the fuel on the basis of clean cooking approach and sustainability. Closeness coefficient 0.60, 0.81and 0.650 was found for LPG, Biogas and PNG, respectively. However, the biogas system (0.81) shows the most potential for a clean and sustainable cooking approach. The analysis shows that the cooking system is constrained by various factors such as economic feasibility, ease of use, availability of cooking fuel and social acceptance of such fuel.

Abstract
Anopheles stephensi is an invasive malaria vector that is endemic to south Asia and the Arabian Peninsula. It was recently reported in the Horn of Africa countries including Djibouti (2012), Ethiopia, Sudan (2019), Somalia (2019) and most recently Nigeria (2020). This mosquito is a competent vector for both Plasmodium falciparum and P. vivax. It is characterized by a high degree of behavioral plasticity and the ability to reproduce in various types of breeding sites including containers and therefore has the potential to propagate malaria transmission in rapidly urbanizing settings with poor drainage and disposal of waste containers. The World Health Organization (WHO) has called on all countries to scale up surveillance efforts to detect and report invasion by this vector and institute appropriate and effective control mechanisms. In Kenya, the Division for National Malaria Program (DNMP) and its partners have been conducting entomological surveillance in all coastal and northern counties that are suspected to be at risk of An. stephensi invasion as well as in all counties at risk of malaria. These efforts were supported by molecular surveillance of all unidentified Anopheles mosquitoes from other studies conducted by the Kenya Medical Research Institute (KEMRI) to try and identify An. stephensi. In this article, we report the first detection of An. stephensi in two sub counties of Marsabit County, Kenya in December 2022. We used Polymerase Chain Reaction (PCR) as the primary method of identification and confirmed results using morphological keys and sequencing of the ITS2 region. With the detection of this vector in Kenya, there is an urgent need for intensified surveillance to determine its occurrence and distribution and develop tailored approaches towards control to prevent further spread.

Abstract
As important components of enzymes and coenzymes involved in energy transfer and Wood-Ljungdahl (WL) pathways, Fe2+ and Ni2+ supplementation may promote the acetate synthesis through CO2 reduction by the microbial electrosynthesis (MES). However, the effect of Fe2+ and Ni2+ addition on acetate production in MES and corresponding microbial mechanisms have not been fully studied. Therefore, this study investigated the effect of Fe2+ and Ni2+ addition on acetate production in MES, and explored the underlying microbial mechanism from the metatranscriptomic perspective. Both Fe2+ and Ni2+ addition enhanced acetate production of the MES, which was 76.9% and 110.9% higher than that of control, respectively. Little effect on phylum level and small changes in genus-level microbial composition was caused by Fe2+ and Ni2+ addition. Gene expression of ‘Energy metabolism’, especially in ‘Carbon fixation pathways in prokaryotes’ was up-regulated by Fe2+ and Ni2+ addition. Hydrogenase was found as an important energy transfer mediator for CO2 reduction and acetate synthesis. Fe2+ addition and Ni2+ addition respectively enhanced the expression of methyl branch and carboxyl branch of the WL pathway, and thus promoted acetate production. The study provided a metatranscriptomic insight into the effect of Fe2+ and Ni2+ on acetate production by CO2 reduction in MES.
Analysis of flow characteristics of cylindrical and helical type multi-lobe roots blower
Authors: Tran Ngoc-Tien , Nguyen Duc-Minh 
Published: January 2023

Roots blower is a positive displacement machine that has the advantage of a larger flow than conventional blowers. Roots blowers are widely used in industrial production such as chemicals, food, medical, etc. However, during actual operation, this type of machine often achieves low performance. One of the issues that greatly affect performance is the flow characteristics of the blower. Flow characteristics include factors related to flow rate, pressure, and flow phenomena in the blower chamber. Flow characteristic analysis is a complex problem in hydraulic machines. Flow analysis helps to investigate the motion of the flow to design high-performance machines. This study uses a mathematical model of gear theory to design the rotor profile with cylindrical and helical lobes of the multi-lobe Roots blower. The rotor profile is formed on the principle that the ellipse rolls without slipping on the base circle. On the basis of the mathematical model of the rotor profile, the paper compares the flow rate and pressure characteristics of the two blowers. The fluid dynamics analysis model was built on ANSYS software. The structural grid model is also built to increase the computational efficiency of the mathematical model. The lobes are embedded and rotated in the blower chamber. The results show that with the same radial and axial dimensions, the cylindrical lobe has a larger flow. However, the helical lobe has a more stable flow quality than the cylindrical lobe (15.2 % less flow fluctuation). In terms of pressure, the helical lobe type has a higher pressure than the cylindrical lobe type. In addition, the helical lobe type also reduces the influence of eddy currents acting on the blower chamber walls and rotors. That results in increased blower efficiency. The results of the paper will be a reliable basis for reducing time in the development of multi-lobe Roots blowers with high performance
A theoretical method of describing the interaction of raw cotton with moving working bodies of cotton-cleaning machines
Authors: Veliev Fazil 
Published: January 2023

A theoretical regularity of the general behavior of raw cotton as a porous medium in the technological processes of its mechanical processing is substantiated for the first time. The speed of sound in a porous cotton medium is determined. The effect of additional force stresses inside the cotton medium, caused by the filtration of the air component from cotton raw materials during the introduction of the working body, is disclosed. A generalized equation is obtained that describes the force stress in a cotton medium when exposed to a variety of shapes of working bodies of cotton machines. A method for calculating the damage to seeds and cotton fibers in the process of interaction with the working bodies of processing machines is proposed.
In the process of processing raw cotton or cotton fiber, the fibrous mass is sharply mechanically affected by organs on the work of organs in the area of inflammation or disease, while complex processes occur inside the fibrous mass associated with a change in the measurement of density and pressure in it. Stresses in the fibers in the presence of conditions of high density of body mass, which can be manifested by plastic deformation, shortening of the fibers and severity of quality. The derived theory for the stress state of cotton raw materials in the process of processing allows to use it practically in all important issues of describing the damage of fiber and cotton seeds in the technological operations of primary processing of cotton

Published: January 2023

Strategic alignment from a performance perspective is difficult to achieve manually. Transparently aligning organizational strategy to each employee’s key performance indicators reduces the risk of duplication and redundancies in performances. Executive Decision Support Framework (EDSF) results in efficiency, cost reduction, and employee satisfaction when their performance is aligned with organizational goals on a continuous basis. This study posits that achieving optimum strategic alignment for the organization and reducing inefficiencies is a function of data and its ensuing analytics.
This paper presents mathematical evidence to confirm that Performance Management of Strategy is integral to an Executive Decision Support Framework (EDSF).
A mixed method research approach was followed where semi-structured interviews were held with Chief Information Officers. The semi-structured interviews formed the basis of survey design. The survey questionnaires were qualitatively analysed using structural equation modelling and the maximum likelihood estimates method, to mathematically prove Performance Management of Strategy is an integral part of Executive Decision Support Framework
This research provides evidence that Performance Management of Strategy is integral to and must be contained in the Executive Decision Support Framework.
Performance Management of Strategy is mathematically linked to an EDSF. Although Performance Management of Strategy comprises latent variables, there is a strong correlation between information quality and an EDSF.

Published: January 2023

Introduction. The effective and safe management of dyslipidemia is an important step in the treatment of non-alcoholic fatty liver disease (NAFLD).Aim. To evaluate the experience of the use of dioscorea drug in the treatment of patients with NAFLD and dyslipidemia.Materials and methods. The effectiveness of a six-month course of dioscorea monotherapy of dyslipidemia was evaluated in 30 patients diagnosed with NAFLD. The observation period was 24 weeks and included 3 visits: before treatment, at week 12 and 24 of the therapy. Changes in complaints, values of lipidograms and biochemical blood tests, liver elastometry were assessed over time, quality of life was measured by SF-36 questionnaire.Results. A decrease in the frequency of the initially recorded symptoms such as weakness, fatigue, pain or feeling of heaviness in the epigastric region and upper abdomen, flatulence, anorexia, nausea/heartburn was observed by week 12. No flatulence and nausea were recorded by week 24, the frequency of the remaining symptoms did not exceed 3-20%. During a six-month course of treatment, the reduction ratio for total cholesterol was 16%, LDL – 27%, triglycerides and atherogenic coefficient – 38% each, HDL level increased by 25%. The decrease in the levels of ALT, AST, gamma-glutamyl transpeptidase, alkaline phosphatase to the reference values was recorded by week 12, which was maintained until visit 3. According to elastometry findings, a decrease in liver stiffness (from 5.5 ± 4.2 to 4.3 ± 1.2 kPa; p < 0.01) and an increase in the percentage of patients corresponding to the METAVIR F0 score (from 43 to 77%, p = 0.01) was reported by visit 3. The therapy resulted in increase of SF-36 total score: physical well-being improved from 46.3 ± 9.1 to 50.3 ± 7.2 scores (p < 0.001); psychological well-being from 40.6 ± 9.2 to 48 ± 6.9 scores (p < 0.001).Conclusion. The inclusion of dioscorea drug in the NAFLD therapy allows to achieve a persistent decrease in atherogenic indices of lipidograms, normalization of biochemical markers of the functional state of liver, which clinically determines the regression and relief of the main symptoms of the disease, improving the patients’ quality of life. From the objective point of view, the decrease in liver stiffness was recorded, which is essential for improving prognosis and reducing the risk of NAFLD progression.
Clinical masks or manifestations of the biliary sample: diagnosis, choice of rational pharmacotherapy
Authors: Minushkin О. N. 
Published: January 2023

Clinical masks or variants of a course of biliary pathology are analyzed in the article. The knowledge of these masks (course variants) is very important because it expands our view of pathology, considerably reduces process of diagnostics and narrows range of nosologies between which differential diagnostics should be carried out. Brief description of the most frequent variants – masks, which form biliary pathology, is presented in the article. Among them the following variants are indicated: 1) cutaneous; 2) cardiac; 3) oesophageal; 4) autonomic dysfunction; 5) pancreatic; 6) dyspeptic; and 7) colitis-like variant. Each variant has a clinical sign that allows it to be classified as biliary pathology. Due to the large number of mask variants, a unified examination programme and diagnostic steps, a probable diagnosis wording is given, allowing the most rational therapy to be chosen. Clinical trial included 120 patients: 10 pregnant women with cholestasis (a small but very important study, as pregnant women are often encountered in therapeutic practice, and they are often subjected to unnecessary investigations, resulting in lost time, and therapy requires markedly more effort), 45 with organic pathology and 65 with problems of functional nosologies. The pharmacotherapy included a highly effective artichoke drug, which has a pathogenetic effect on most of the pharmacological targets and has a choleretic and protective effect. Overall treatment efficacy was 90% with good tolerability and no side effects.
