Authors: Милов П.О. , Воронцов М.К. 
Published: June 2024

Регулирование корпоративных отношений в Российской Федерации началось относительно недавно, а именно в 2013 году, в рамках проведения реформы гражданского законодательства. По этой причине в рамках данных правоотношений до сих пор присутствует ряд актуальных проблем, которые необходимо решать, поскольку отношения, протекающие в рамках корпорации, отличаются не только особой ответственностью, но и зависимостью от внешних обстоятельств. В последнее время практиками отмечается увеличение корпоративных конфликтов, которые во многом возникают по причине недостаточного уровня корпоративного управления. В статье проводится анализ гражданско-правового регулирования корпоративных отношений, а также выделяются отдельные вопросы, требующие внимания не только законодателя, но и исследователей.
The regulation of corporate relations in the Russian Federation began relatively recently, in 2013, as part of the reform of civil legislation. For this reason, within the framework of these legal relations, there are still a number of urgent problems that need to be solved, since the corporate relations are both highly responsible and dependent on external circumstances. Recently, practitioners have noted an increase in corporate conflicts, which largely arise due to insufficient level of corporate governance. The article analyzes the civil law regulation of corporate relations, and also highlights certain issues that require the attention of both legislators and researchers.

Published: June 2024

History taking is an important tool available to the medical student to make a reasonable working diagnosis. The process of clinical reasoning helps give a comprehensive view of the patient’s needs and aids in patient centered care. Though 43.9% of the medicos strongly agreed that diagnosis is an important function of a doctor, only 18.3 % of the men and 10.6 % of the women were convinced that a good diagnosis was possible with case taking alone. Overall, only 7.3 % felt confident in taking a good history. The current study shows that history taking and physical examination is taking a lesser role in diagnosis. Communication with the patient is also seen as not necessary. This descriptive study involves 164 medicos (110 final years and 54 interns) who were administered a predetermined questionnaire. Findings were subjected to tests of significance like Chi square at 5% Level of significance.To identify the importance given to history taking in disease diagnosis among medicos. Undergraduate medical education must ensure training in communication, proper history taking and good examination skills. Small-group skills workshops using role-plays followed by effective feedback are ways to certifiable training in medical colleges.

Abstract

Background: Along the southern shoreline of Lake Malawi, the incidence of schistosomiasis is increasing with snails of the genera Bulinus and Biomphalaria transmitting urogenital and intestinal schistosomiasis, respectively. Since the underlying distribution of snails is partially known, often being focal, developing pragmatic spatial models that interpolate snail information across under-sampled regions is required to understand and assess current and future risk of schistosomiasis.
Methods: A secondary geospatial analysis of recently collected malacological and environmental survey data was undertaken. Using a Bayesian Poisson latent Gaussian process model, abundance data were fitted for Bulinus and Biomphalaria. Interpolating the abundance of snails along the shoreline (given their relative distance along the shoreline) was achieved by smoothing, using extracted environmental rainfall, land surface temperature (LST), evapotranspiration, normalised difference vegetation index (NDVI) and soil type covariate data for all predicted locations. Our adopted model used a combination of two-dimensional (2D) and one dimensional (1D) mapping.
Results: A significant association between normalised difference vegetation index (NDVI) and abundance of Bulinus spp. was detected [log risk ratio -0.83, 95% CI: -1.57, -0.09]. A qualitatively similar association was found between NDVI and Biomphalaria spp. but was not statistically significant [log risk ratio -1.42, 95% CI:-3.09, 0.10]. Analyses of all other environmental data were considered non-significant.
Conclusions: The spatial range in which interpolation of snail distributions is possible appears less than 10km, owing to fine-scale biotic and abiotic heterogeneities. The forthcoming challenge is to refine geospatial sampling frameworks with future opportunities to map schistosomiasis within actual or predicted snail distributions. In so doing, this would better reveal local environmental transmission possibilities.

Published: June 2024

Abstract

Uncertainty presents a challenge in assessing risks, often resulting in outcomes that diverge from reality. System Hazard Identification, Prediction and Prevention (SHIPP), as one of the emerging risk assessment methods, aims to predict and effectively prevent accidents. This study aims to enhance the prediction potential of the SHIPP method by reducing uncertainty by combining Z-numbers and intuitionistic fuzzy logic. The experts' opinions and confidence levels regarding the prior probability of basic events (BEs) were measured using Intuitionistic Z-numbers (IZN). Subsequently, the SHIPP method utilized the obtained results and the actual data on unusual events in the industry to determine the posterior probability of barrier failure and consequences. The practical application of the developed methodology was demonstrated by selecting spherical tanks containing LPG. The results indicated that employing IZN to estimate the prior probability of BEs reduces uncertainty in determining the posterior probability of barrier failure and subsequent consequences. Consequently, enhancing the predictive accuracy of the SHIPP method in estimating the likelihood of unusual events will significantly improve the quality of risk management.

Published: June 2024

Abstract

Microbiological air sampling was performed at six different Sewage Treatment Plant (STP) locations using a six-stage viable cascade impactor to determine the viable mesophilic gram positive and gram-negative bacterial cell count during all seasons, namely the monsoon, post-monsoon, winter, and pre-monsoon. The bioaerosol concentration of gram-positive bacteria ranged from 12±07 to 997±178 CFU m-3 at different sites of STP with peak values in post-monsoon at the aeration tank (997±178 CFU m-3) and lowest values in winter at the final settlement tank (FST). The minimum concentration of gram-negative bacteria was 35±12 CFU m-3 at inlet 1 during the winter season and maximum with 749±126 CFU m-3 at the aeration tank during the post-monsoon season. Univariate ANOVA analysis showed that sampling vs. seasons and sampler stages had the highest individual effect (p=0.000) and no significant interactive effect (p = 0.611) of seasons and stages on gram positive bacterial bioaerosol concentration at inlet 1. The activated sludge treatment facility was the site where highest individual (p=0.000) and interactive effect (p=0.000) were found for gram negative bacterial bioaerosol. The significant higher regression coefficient (R2) values for gram positive and gram-negative bacteria were observed to be 0.866 and 0.915 respectively in the pre-monsoon season between fine and coarse fractions of aerosols. The maximum concentrations for both types of bacteria were found in the respirable size fraction of particles which are less than 4.7 µm in aerodynamic diameter.

Abstract

Fungal biomass is a low-cost and sustainable biosorbent used both actively and passively. This study focused on assessing the efficacy of inactivated and dried biomass of Fusarium sp. in adsorbing Ni2+ and Pb2+ ions from aqueous solutions. The strain underwent sequenced cultivation and was recovered by filtration. Then, the biomass was dried in an oven at 80 ºC and sieved at 0.1 cm mesh. The biosorbent underwent vast characterization, including analysis of the BET surface area, morphology (SEM), chemical composition (XRF and FTIR), thermal behavior (TGA), and surface charge determination (pH-PZC and zeta potential). The biosorption mechanism was elucidated by examining the fit of equilibrium models to the data, encompassing kinetics, isotherm, and thermodynamic analysis. The biosorbent exhibited a neutral charge, a rough surface, a relatively modest surface area, suitable functional groups for adsorption, and thermal stability above 200 °C. Optimal biosorption was achieved at 25 ºC, using 0.05 g of adsorbent per 50 mL of metallic ion solution at an initial concentration ranging from 0.5 to 2. mg.L-1 and at pH 5.5 for Pb2+ and pH 6.5 for Ni2+. Biosorption equilibrium was reached after 240 minutes for Ni2+ and 1,440 minutes for Pb2+. The process was spontaneous, occurring primarily through chemisorption, and capable of remove over 85 % of both metallic ions. These findings underscore the potential of inactive and dry Fusarium sp. biomass (IDFB) as a promising material for the biosorption of Ni2+ and Pb2+. Thus, it contributes to the wastewater management and development of sustainable biosorbents, supporting the achievement of the Sustainable Development Goals (SDGs) outlined in the 2030 Agenda.
Numerical quadrature methods for systems of linear ODEs with constant coefficients
Authors: Lin Fu-Rong , Yang Xi , Zhang Gui-Rong 
Published: June 2024

Abstract

In this paper, we consider high precision numerical methods for the initial problem of systems of linear ordinary differential equations (ODEs) with constant coefficients. It is well-known that the analytic solution (AS) of the initial value problem for a system of linear ODEs with constant coefficients involves a matrix exponential function, and an integral whose inte-grand is the product of a matrix exponential function and a vector-valued function. We mainly consider numerical quadrature methods for the integral term in the analytic solution. To simplify the discussion, we consider the case where the coefficient matrix is real and symmetric, and compute the corresponding matrix exponential function by using matrix spectral factorization. We propose a product quadrature (PQ) method, including its detailed computational procedure and its convergence analysis. Then the proposed methods are applied to the initial-boundary value problem for a heat conduction equation and a Riesz space fractional diffusion equation, respectively. Applying the central finite difference operator to discretize the second-order space derivative or a weighted shifted Grünwald difference (WSGD) operator to discretize the Riesz space fractional derivative, the initial-boundary value problem for the above mentioned equations is transformed to the initial value problem of a system of linear ODEs with constant coefficients. We then transform the systems of linear ODEs to symmetric ones if necessary. Numerical results presented to demonstrate the effectiveness of the proposed methods.

Abstract

This research work explores the development and application of layer-by-layer modified electrochemical apta-sensor for the precise monitoring of HER2, a crucial biomarker associated with breast cancer. The surface of the screen-printed carbon electrode was modified with gold nanoparticle (Au-NP) and TiVC MXene catalyst plus Pb2+ loaded aptamer (SPCE/TiVC-MXene/Au NPs/Pb2+-aptamer), which showed a high selectivity and affinity toward HER2 and offered a sensitive detection platform. The MXene nano-layer was synthesized and characterized by FT-IR, MAP, EDS, and TEM methods and used as a substrate to improve electrochemical conductivity and loading of biological recognition element. The difference of stripping signals of the Pb2+ from the SPCE/TiVC-MXene/Au NPs/Pb2+-aptamer before and after incubation in HER2 solution was selected as analytical response to achieve a reliable and quantitative analysis for HER2 concentrations. The results demonstrate a linear dynamic range of 1.0–1200 pg/mL for monitoring of HER2 with limit of detection of 50 fg/mL. Agood affinity of fabricated aptasensor to HER2 in the presence some other biomarkers such as PR, ER, and CEA confirmed the selectivity of the fabricated biosensor towards HER2.
On maximum residual block Kaczmarz method for solving large consistent linear systems
Authors: Sun Wen-Ning , Qin Mei 
Published: June 2024

Abstract

For solving large consistent linear systems by iteration methods, inspired by the maximum residual Kaczmarz method and the randomized block Kaczmarz method, we propose the maximum residual block Kaczmarz method, which is designed to preferentially eliminate the largest block in the residual vector rk at each iteration. At the same time, in order to further improve the convergence rate, we construct the maximum residual average block Kaczmarz method to avoid the calculation of pseudo-inverse in block iteration, which completes the iteration by projecting the iteration vector xk to each row of the constrained subset of A and applying different extrapolation step sizes to average them. We prove the convergence of these two methods and give the upper bounds on their convergence rates, respectively. Numerical experiments validate our theory and show that our proposed methods are superior to some other block Kaczmarz methods.

Abstract

Introduction. To mitigate gastroparesis as well as other post-operative complications, we undertook a prospective multicenter study to assess the feasibility, safety, and efficacy in the short-term outcomes of laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation.Methods. A prospective descriptive study on 37 patients with laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation from January 2019 to March 2023. The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated.Results. In our study, all patients were male, with choking as the predominant symptom (45.9%). Esophageal cancer incidence was similar between middle and lower thirds. Nodules were the primary finding on esophagoscopy (48.6%). Preoperative pyloric dilation averaged 31.2 minutes without complications. Surgical duration ranged from 225 to 400 minutes (mean 305). Gastric tube fluid volume averaged 148.9 ± 110.66 ml per day. Among 34 post-operative cases underwent gastric circulation scans, most had non-dilated stomachs with efficient pyloric drug circulation. Three cases required prolonged ventilation, precluding pyloric circulation scans. Four patients developed chylous fistula, one requiring chest tube embolization. Recurrent laryngeal nerve damage occurred in 10.8% of cases.Conclusion. After evaluating esophageal cancer patients undergoing laparoscopic whole-stomach esophagectomy with preoperative pyloric balloon dilatation, it was found that this procedure is safe, effective, and significantly reduces postoperative gastroparesis and related complications.
