BACKGROUND
Conventional five-port laparoscopic surgery, the current standard treatment for colorectal carcinoma (CRC), has many disadvantages.
AIM
To assess the influence of reduced-port laparoscopic surgery (RPLS) on perioperative indicators, postoperative recovery, and serum inflammation indexes in patients with CRC.
METHODS
The study included 115 patients with CRC admitted between December 2019 and May 2023, 52 of whom underwent conventional five-port laparoscopic surgery (control group) and 63 of whom underwent RPLS (research group). Comparative analyses were performed on the following dimensions: Perioperative indicators [operation time (OT), incision length, intraoperative blood loss (IBL), and rate of conversion to laparotomy], postoperative recovery (first postoperative exhaust, bowel movement and oral food intake, and bowel sound recovery time), serum inflammation indexes [high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6)], postoperative complications (anastomotic leakage, incisional infection, bleeding, ileus), and therapeutic efficacy.
RESULTS
The two groups had comparable OTs and IBL volumes. However, the research group had a smaller incision length; lower rates of conversion to laparotomy and postoperative total complication; and shorter time of first postoperative exhaust, bowel movement, oral food intake, and bowel sound recovery; all of which were significant. Furthermore, hs-CRP, IL-6, and TNF-α levels in the research group were significantly lower than the baseline and those of the control group, and the total effective rate was higher.
CONCLUSION
RPLS exhibited significant therapeutic efficacy in CRC, resulting in a shorter incision length and a lower conversion rate to laparotomy, while also promoting postoperative recovery, effectively inhibiting the inflammatory response, and reducing the risk of postoperative complications.

Though political parties are increasingly adopting social media to increase voter support, the efficacy of social media campaign strategies in enhancing political fortunes remains a subject of discussion in Ghana. This study explored the views of Ghanaians on the use of social media campaign strategies as a political communication tool. In all, 384 social media users who are voters residing within the Tema Metropolis participated in the study. Data was obtained using a questionnaire and analyzed descriptively. The study observed that Ghanaian political parties have a strong presence on social media. Again, Ghanaian political parties effectively rely on social media platforms to engage electorates. Also, they effectively use social media distribute creative and visually appealing contents about their policies and achievements to the electorates. Further, they adopt campaign-specific hash tags which are creative, memorable, catchy, and engaging to help them to capture attention of voters. The study concludes by accentuating the need for political parties to employ social media for constructive dialogue and engagement with voters to amplify the impact of social media campaigns on the political fortunes in Ghana. Finally, practical implications of the findings have been provided to facilitate effective application of social media campaign strategies for democratic governance.

Published: June 2024

Leptospirosis represents a significant global public health problem due to its epidemiological impact, complex pathogen biology, and diverse clinical manifestations. Effective treatment, management, and preventive measures, including vaccination, are vital for addressing this disease. Lsa46, a surface-exposed outer membrane protein in leptospires, plays a crucial role in pathogenesis. In this study, we utilized multiple epitopes predicted from Lsa46, validated in previous study, to design a potential vaccine candidate construct. The antigenicity, allergenicity, autoimmunity, population coverage, immune simulation, molecular interactions etc. were assessed using various computational tools. 3D structure modeling revealed a stable and high quality model for epitope constructs. Immune simulation confirmed a robust immune response induced by the Designer Epitope construct, including IgG, IgM, MHCI, MHCII, cytokines, and interleukins production. Interaction analysis with immune cells and receptors, such as TCRαβ, TCRγδ, and TLRs, provided insights into the epitope construct's potential immunogenic response. Docking studies with TLR2 and TLR4 indicated their interaction with the epitope, suggesting their involvement in the immune response against leptospirosis. Further experimental validations are required to confirm these prediction results.

Characterizing clouds with the CCClim dataset, a machine learning cloud class climatology
Authors: Kaps Arndt , Lauer Axel , Kazeroni Rémi , Stengel Martin , Eyring Veronika 
Published: June 2024

Abstract. We present the new Cloud Class Climatology (CCClim) dataset, quantifying the global distribution of established morphological cloud types over 35 years. CCClim combines active and passive sensor data with machine learning (ML) and provides a new opportunity for improving the understanding of clouds and their related processes. CCClim is based on cloud property retrievals from the European Space Agency's (ESA) Cloud_cci dataset, adding relative occurrences of eight major cloud types, designed to be similar to those defined by the World Meteorological Organization (WMO) at 1° resolution. The ML framework used to obtain the cloud types is trained on data from multiple satellites in the afternoon constellation (A-Train). Using multiple spaceborne sensors reduces the impact of single-sensor problems like the difficulty of passive sensors to detect thin cirrus or the small footprint of active sensors. We leverage this to generate sufficient labeled data to train supervised ML models. CCClim's global coverage being almost gapless from 1982 to 2016 allows for performing process-oriented analyses of clouds on a climatological timescale. Similarly, the moderate spatial and temporal resolutions make it a lightweight dataset while enabling straightforward comparison to climate models. CCClim creates multiple opportunities to study clouds, of which we sketch out a few examples. Along with the cloud-type frequencies, CCClim contains the cloud properties used as inputs to the ML framework, such that all cloud types can be associated with relevant physical quantities. CCClim can also be combined with other datasets such as reanalysis data to assess the dynamical regime favoring the occurrence of a specific cloud type in association with its properties. Additionally, we show an example of how to evaluate a global climate model by comparing CCClim with cloud types obtained by applying the same ML method used to create CCClim to output from the icosahedral nonhydrostatic atmosphere model (ICON-A). CCClim can be accessed via the following digital object identifier: https://doi.org/10.5281/zenodo.8369202 (Kaps et al., 2023b).

В результате анализа работы прошивного стана выявлена необходимость модернизации мехатронной системы позиционирования рабочих валков и внедрения интеллектуальной системы, позволяющей повысить качество проката. Основная проблема – образование дефектов на торцах гильз при их прокатке на прошивном стане. Излишки необходимо срезать и утилизировать, так как для прокатки одной заготовки используется больше сырья, чем требуется. Для устранения данной проблемы необходимо изменять степень поджатия заготовки в процессе прокатки, тем самым формируя профиль, позволяющий снизить объемы нежелательных изменений на торцах труб при прокате. В настоящее время в прошивном стане имеется оборудование зарубежного производства, трудности с закупкой которого могут привести к простоям. Агрегат, кроме того, работает только в ручном или полуавтоматическом режиме. В статье рассмотрена возможность замены оборудования отечественными аналогами и написана программа для управления им, в том числе в автоматическом режиме. Разработана программа визуализации и управления. Для определения положения заготовки в стане и изменения степени поджатия гильзы в автоматическом режиме внедрена система управления с нейронной сетью.
As a result of the analysis of the operation of the piercing mill, there was revealed the need to modernize the mechatronic system for positioning work rolls and the introduction of an intelligent system to improve the quality of rolled products. The main problem is the formation of defects at the ends of the sleeves during their rolling on a piercing mill. Surplus must be cut off and disposed of. As a result, it turns out that more raw materials are used for rolling one billet than required. To eliminate this problem, it is necessary to change the degree of preload of the workpiece during rolling, thereby forming a profile that makes it possible to reduce the volume of undesirable changes at the ends of the pipes during rolling. At the moment, the mill has foreign equipment, difficulties with the purchase of which can lead to downtime. Also, the unit works only in manual or semi-automatic mode. The article considers the possibility of replacing equipment with domestic analogues and a program has been written to manage it, incl. in automatic mode. There was developed visualization and control program. To determine the position of the workpiece in the mill and change the degree of compression of the sleeve in automatic mode are developed a neural network.

Предложен испытательный стенд, реализующий метод испытания с периодическим смачиванием образцов, имитирующий условия внутренней поверхности газопровода. Это новое научно-техническое решение для проведения коррозионных испытаний в условиях углекислотной коррозии, в том числе и для оценки стойкости сталей к локальной коррозии. Испытания с его использованием показали, что за достаточно короткий период стенд позволяет оценить скорости общей и локальной коррозии трубных сталей. Наличие большого числа испытательных ячеек (до 14) в коррозионном стенде и возможность варьирования коррозионных условий в них позволяет оперативно проводить исследования основных коррозионно-опасных факторов (минерального состава водной фазы, парциального давления и температуры). Данный метод коррозионных испытаний чувствителен и при невысоких содержаниях СО2.
A test stand is proposed that implements a test method with periodic wetting of samples, simulating the conditions of the inner surface of a gas pipeline. This is a new scientific and technical solution for conducting corrosion tests under conditions of carbon dioxide corrosion, including for assessing the resistance of steels to local corrosion. Tests with its use have shown that in a fairly short period of time, the stand makes it possible to estimate the rates of general and local corrosion of pipe steels.The presence of a large number of test cells (up to 14) in the corrosion stand and the possibility of varying the corrosion conditions in them allows you to quickly study the main corrosion-hazardous factors (the mineral composition of the aqueous phase, partial pressure and temperature). This corrosion test method is also sensitive at low CO2 levels.

Published: June 2024

Получены зависимости, устанавливающие связь между напряжениями натяжения, максимальными напряжениями и параметрами несимметричной неплоскостности полос при упругом растяжении для биквадратичного закона распределения напряжений по ширине. Выполнен сравнительный анализ полученных зависимостей с известными для квадратичного закона распределения напряжений. Полученные зависимости позволяют в случае частичного скрытия дефекта в натянутой полосе более точно рассчитать напряжения и параметры неплоскостности и, соответственно, более правильно выбрать режимы ее обработки (например, при дрессировке, горячем цинковании, непрерывном отжиге и др.). Более точный расчет максимальных напряжений по ширине с учетом несимметричности дефекта позволяет снизить вероятность обрывности полос и стабилизировать технологию их производства. Полученные зависимости могут быть применены в системах автоматического регулирования плоскостности при производстве холоднокатаных полос.
The dependencies establishing the relationship between the tension stresses, maximum stresses and parameters of asymmetric non-uniformity of strips during elastic tension for the bi-quadratic law of stress distribution over the width have been obtained. A comparative analysis of the obtained dependences with those known for the quadratic law of stress distribution is performed. The obtained dependencies allow to more accurately calculate the stresses and parameters of non-uniformity in case of partial concealment of a defect in the stretched strip and, accordingly, to more correctly adjust its treatment modes (for example, during dragging, hot-dip galvanizing, continuous annealing, etc.). A more accurate calculation of the maximum stresses along the width, taking into account the asymmetry of the defect, makes it possible to reduce the probability of strip breakage and stabilize the technology of their production. The obtained dependencies can be applied in automatic flatness control systems the production of coldrolled strips.
Salini test: history and trends of law enforcement practice
Authors: Skvortsov O. Yu. 
Published: June 2024

The subjectof this article is the international law enforcement practice developing in relation to the concept of investment. The formation of this practice takes place in numerous decisions of investment arbitration. The Salini test plays an important role in this practice, which is an investment arbitration decision that has become the flagship of the development of the practice of applying international investment law and its principles.The purposeof the article is to identify trends in the decisions of investment arbitration, in which the concept of investment is interpreted, as well as in the doctrinal justification of approaches to this problem.The methodologyof the study is a comparative legal analysis of those concepts that are the basis of the Salini test, as well as competing theories with it.Main results. The reason for the appearance of the Salini test was the impossibility of a total consensus of states regarding the legal formalization of the concept of "investment". This impossibility has an objective character, since the investments of resources in one or another sphere have such significant differences that they cannot be taken into account within the framework of a single legal paradigm. In addition, the subjective factor is also important for the formulation of this concept, since states endowed with different roles – either as recipients of investments or as investors have divergent interests that cannot be realized within the framework of a single legal approach.Conclusions. Investment arbitration has to a certain extent demonstrated the ability to overcome the differences that exist between different states regarding the key concept of investment law. It was in the arbitration decisions, and above all in the Salini test, that the signs of the key concept of investment law were identified, which together constitute its content. The content of the Salini test is that the concept of investment is formulated based on the identification of the following criteria: (1) investment of assets; (2) a certain duration of the investment of assets; (3) risky nature of investments; (4) significant economic importance for the recipient state.In addition, the author of the article comes to the conclusion that, despite the fact that the Salini test accumulated the main legal ideas about the regulation of investment activity, the amorphous nature of the concept of investment determines a high degree of its uncertainty in relation to specific situations. This provokes a continuation of the discussion regarding legally significant investment criteria.

Published: June 2024

В данной статье рассмотрен алгоритм решения задачи оптимизации с помощью аппарата обратных вычислений. Рассмотрена задача квадратичного программирования с ограничением в виде равенства, то есть, конкретно задача оптимизации закупок фирмы, в котором нужно определить количество заказываемых товаров таким образом, чтобы максимально удовлетворить спрос потребителя при минимальном бюджете. Предложенный алгоритм решения может быть применен в системах поддержки принятия решений для планирования максимальной закупки товаров организации. Данный алгоритм является более простым в компьютерной реализации по сравнению с классическими методами, то есть, чтобы найти решение задачи оптимизации закупок просто нужно решить систему уравнений. В результате получили одинаковые решения для трех методов: метода на основе обратных вычислений, метода штрафов и метода множителей Лагранжа.
