Authors: Slonetskyi Boris Ivanovich , Verbitskiy Igor Volodimirovich , Kotsiubenko Valeria Olegivna
Published: July 2024

The purpose of the work is to analyze the results of the use of optimized diagnostic and therapeutic tactics in patients with strangulated abdominal hernias without resection of the hollow organ.

Materials and methods: The work is based on the analysis of the results of surgical treatment of 665 patients with strangulated abdominal hernias without resection of the hollow organ, who were divided into 2 groups depending on the features of the diagnostic and treatment tactics. Unlike the patients of group 1, the following diagnostic tactics were used in group 2: substantiated laparoscopic diagnosis of abdominal organs; mandatory biochemical assessment of hernia water; mandatory intraoperative instrumental assessment of the state of the strangulated organ; expansion of indications for the use of laparoscopic interventions and components of the comprehensive Fast track program; substantiated complex prevention of malignancy. The clinical diagnostic algorithm included laboratory, instrumental and biochemical research methods.

Results: The use of priority diagnostic and therapeutic tactics in the patients of group 2 allowed to increase the number of laparoscopic hernioplasty by 49.34%, the number of allohernioplasty by 18.62%, among which the “Sublay” technique was preferred for strangulated ventral hernias. This was accompanied by a decrease in the pain syndrome on the VAS scale during the four days of observation, both during coughing and at rest, and amounted to only 2.21 ± 0.29 points on the fourth day when at rest. In addition, and after 12 months, the patients of group 2 observed a better recovery according to the SF-36 questionnaire, which amounted to 76.77±6.63 points for the assessment of the general state of health, 70.81±5.86 points for the assessment of physical functioning, 68.88±5.37 points for the assessment of role functioning due to physical condition, 68.03±5.92 points for the assessment of role functioning due to emotional state, and social activity was characterized by 72.82±5.52 points.

Conclusions: 1. The proposed diagnostic and treatment tactics in the patients of group 2 with strangulated abdominal hernias without resection of a hollow organ, in contrast to patients in group 1, made it possible to increase the number of laparoscopic operations to 227 (66.37%) in contrast to 55 (17.03%) in the first group, which was accompanied by a decrease in pain syndrome on the VAS scale on the fourth day when coughing from 4.35 ± 0.38 points to 2.97 ± 0.43 points.

2. The expansion of indications for the use of laparoscopic operations in patients of group 2, in contrast to patients of group 1, led to a decrease in the postoperative complications by 10.48% and the postoperative mortality by 2.29% and was characterized by better postoperative rehabilitation according to the assessment of the patients’ condition after 12 months according to the SF-36 questionnaire..

Optimization of stable genetic transformation protocol in castor (Ricinus communis L. cv. TMV 5) using beta glucuronidase reporter gene for pioneer of desirable genes
Authors: Ganesh Kumari K. , Jayabalan N.
Published: July 2024

The simple and stable protocol was standardised for castor (Ricinus communis L. cv. TMV 5) genetic transformation using Agrobacterium tumefaciens strain LBA4404 harbouring the binary plasmid pBAL2 (18.8 kb). Cotyledonary nodes from ten days old, in vivo seedlings were utilized as target cells for Agrobacterium mediated transformation. Explant pre-culture studies were carried out at 2, 4, 6, 8, 10 and 12 day intervals. The 4th day old explants cultivated on mMS medium (MS medium+B5 Vitamins) using plant growth regulators had the highest response percentage (50.6%). Kanamycin (0-175 mg/L) and Hygromycin (0-13 mg/L) sensitivity in well-developed shoots was investigated. Of the two antibiotics, Kanamycin 50 mg/L and Hygromycin 3 mg/L was found optimum. Different levels of acetosyringone (0-200 mg/L) were used in the co-cultivation medium to study the transformation efficiency of castor. Among the different concentrations, maximum number of explants showed GUS expression at 100 mg/L of acetosyringone in the co-cultivation medium at 2 days of co-cultivation period and the Cotyledonary node produced multiple shoots development and plantlet establishment in 0.3 mg/L TDZ, 0.6 mg/L PF-68, kanamycin 50 mg/L, 0.3 mg/L GA3, 1.5 mg/L IBA and 0.6 mg/L AgNO3. The rooted shoots were successfully acclimatized. Histochemical GUS assay was used to monitor T-DNA delivery into the target cells. PCR and Southern hybridization were used to confirm the transformants with the NPT II and GUS gene. A very high frequency (29.3%) of β-glucuronidase (GUS) gene expression was obtained through Agrobacterium-mediated gene transfer into cotyledonary node explants of Castor. The standardized protocol would be useful for Agrobacterium-mediated genetic transformation of Cator with desirable gene of agronomic importance.

Published: July 2024

Abstract: This study focuses on exploring the potential of artificial intelligence as an alternative, effective, and user-preferred tool for answering inquiries, compared to traditional methods such as FAQs or email and ticketing systems. The study highlights how AI can enhance efficiency and accuracy in processing and responding to inquiries from readers, authors, and reviewers, by providing immediate and customized answers based on the analysis of information available on the journal's website and the data fed to the chatbot. Through in-depth discussions and an analysis of the inquiries received over a full six months, totaling about 3000 inquiries, the study demonstrates the good ability of the chatbot to understand complex inquiries and provide satisfactory answers. The study indicates that chatbots can reduce the workload on editorial teams of scientific journals by automating responses to routine inquiries, allowing staff to dedicate more time to editorial and academic tasks. One of the key aspects of training is teaching the chatbot to provide correct answers to various inquiries and to avoid responding to negative or redundant inquiries. The research explores the challenges of applying AI in this context, including the need to train smart models to understand specific academic language and ensure accuracy in responses, as well as addressing privacy concerns and data security. The importance of designing flexible and adaptable AI systems to meet the diverse requirements of different scientific journals and their users is emphasized. The study concludes that artificial intelligence is a promising tool for improving the interaction between academic journals and their communities, offering an effective alternative to traditional systems. It highlights the necessity for ongoing research and development to enhance AI capabilities. Notably, the AI tool currently lacks a direct method for correcting its wrong answers, which is one of the most effective learning tools used by parents to correct their children's answers. One of the key recommendations of the study is that AI training should be conducted in stages.
Integrated Orbital Design Method for Manned Lunar Exploration with Relaxed Temporal Constraints
Authors: Li Zeyue , Yang Zhen , Li Haiyang , Zhou Wanmeng
Published: July 2024

An integrated orbital design method with relaxation of temporal constraints is presented, focusing on improving the efficiency of complex-flight-mission planning for manned lunar exploration. Crewed lunar exploration programs are characterized by a variety of spacecraft and multiple trajectory stages. The aim of integrated design is to realize automatic splicing of such multistage trajectories under coupled temporal and spatial constraints. Currently, integrated mission–orbital design is mainly achieved through decoupling and iterative methods, and the matching of boundary constraints usually requires human-in-the-loop intervention. In this paper, a novel integrated orbital splicing process is proposed from the viewpoint of the temporal dimension, considering the temporal relationships between orbital stages and the scheduling flow of the underlying dynamical models. Relaxation factors are introduced for weak temporal constraints to improve the overall convergence of orbital splicing calculations across different stages. A comprehensive temporal constraint model and subsequently an integrated orbital design model are constructed. The proposed method is validated by simulation of flight missions targeting the high-latitude regions of the moon.
Modeling Medium-Term Debris Cloud of Satellite Breakup via Probabilistic Method
Authors: Wen Changxuan , Jin Zihan , Peng Chao , Qiao Dong
Published: July 2024

Accurately modeling the evolution of debris clouds from satellite breakups is necessary for assessing the collision risk to space assets. Generally, the evolution of debris clouds can be divided into short-, medium-, and long-term phases. Compared to the short- and long-term phases, the study on the medium-term phase was insufficient. This paper proposes a probabilistic method to model the medium-term evolution of a debris cloud. First, a satellite breakup event can be characterized by a probabilistic density distribution of the initial velocity vectors of all fragments. Then, the distribution in the initial velocity can be transformed to that in three classic orbital elements, i.e., semimajor axis, eccentricity, and inclination. Given that the driving force of medium-term evolution is the [Formula: see text] perturbation and that [Formula: see text] has no secular contribution to these three classic orbital elements, the distribution of classic orbital elements remains stationary during the evolution. This feature can be exploited to express the probabilistic density distribution of any given target position in terms of the density distribution of the classic orbital elements by changing variables. Finally, 16 one-variable equations with analytical first derivatives were formulated to find the proper inverse mapping from the given position to the classic orbital elements, and the Jacobian matrix of the inverse mapping was derived. Medium-term debris clouds resulting from two typical breakup velocity distributions were tested using the proposed method. Results show that the proposed method can accurately simulate the evolution of the clouds’ geometrical extent and density flow.
Closed-Loop Control of Dynamic Oblique Shock with Arc Plasma
Authors: Liu Fan , Wang Bo , Huang Hongchao , Yan Hong
Published: July 2024

The fluctuations caused by the dynamic shock wave and its interaction with the boundary layer bring formidable challenges for aerodynamic design and stable control of supersonic aircraft. The mechanism of closed-loop control for dynamic oblique shock stabilizing with arc plasma is numerically studied. Two types of dynamic oblique shocks are formed in supersonic airflow by a compression ramp rotation and incoming Mach number variation, respectively. A closed-loop controller is established to connect the arc plasma deposited power with the pressure ratio across the dynamic shock by using the proportional-integral method. It realizes the shock pressure ratio stabilized in the desired target value with a local overshoot appearing at the initial excitation and a more stable flow downstream of the oblique shock during excitation state for both types of dynamic shock control. The effects of arc plasma length and ramp rotating speed on the closed-loop control for the dynamic shocks induced by ramp rotation are further discussed. Results show that the arc plasma with longer length is more favorable to the dynamic oblique shock control with lower energy consumption and total pressure loss. The pressure ratio fluctuation is increased at higher ramp rotation speed, but its standard deviation is still limited to 0.3% of the desired target value during excitation state.
Multi-dimensional early warning of the entire supply chain of power materials based on RFID technology
Authors: Huang Siping , Jiang Jianwu , Chen Yiliang , Song Xinlei , Ma Wanyi
Published: July 2024

Early warning system needs to process a large amount of real-time data, and carry out in-depth analysis and mining of these data to identify potential risks and hidden dangers. However, existing data processing and analysis capabilities may not be able to meet this demand. To this end, a multi-dimensional early warning of the entire supply chain of power materials based on radio frequency identification (RFID) technology is designed. According to the real-time failure probability of power materials, the probability of early warning accidents is calculated and classified, and the risk is graded based on these probabilities. Through the methods of bonus points, deduction points, and grade evaluation, the risk early warning indicators of different stages in the whole supply chain of power materials were quantified. The objective and rationality of risk assessment can be ensured by means of comprehensive weight. A multi-dimensional early warning system based on RFID technology is established, combining multiple linear regression models and particle swarm optimization algorithms to determine the time window of multi-dimensional early warning, and carry out dynamic monitoring and early warning of the supply chain. The experimental results show that the early warning effect of the design method can reach 95% and the highest early warning effect can reach 98% at 10 s. The average warning error is only 2.91%, and the average warning time is only 1.34 s, which is more accurate in identifying the number of first-level risks, second-level risks, and third-level risks.

Published: July 2024

As a result of the analysis of the history of the family Yponomeutidae study the three conditional stages were outlined mainly based on the used research methods. The first stage, which began in the first half of XVIII century and ended at the beginning of the XX century, covers the period from the first descriptions with illustrations of larva nests and the external features of the preimaginal and imaginal stages to the use of genital characters in the species identification. From the latter the second stage starts and ends before the introduction of the molecular genetic method for study of taxonomic diversity. During this stage the study of the ermine moths were expanded to comparative morphological research, elucidation of the homology of genital structures based on their functional morphology and development of taxonomy based on phylogenetic analyses. The third stage begins from the end of XX century, when researchers started to use molecular markers to solve taxonomic problems in the group. According to the results of many years of research, the fauna of yponomeutid moths has been studied in Russia and adjacent countries very unevenly and, in general, insufficiently. Currently, the species diversity of ermine moths in the Russian Far East is 38 species from 10 genera, significantly inferior to that of China (70 species of 17 genera) and less to that in Japan (46 species of 16 genera). However, the species diversity of ermine moths in the Russian Far East exceeds the known diversity of this group in Korea (25 species from 10 genera).

Military expenditures have a significant impact not only on the socioeconomic condition of a state but also on the regional balance of power. In this study it will be examined the relationship between military expenditures and economic conditions in Azerbaijan and Armenia and impacts of military expeditures on the regional balance. In the context of the diplomatic history from the First Karabakh War to the Second Karabakh War, the regional balance between the two states is clarified. Then the complex relationship between military expenditures and economic conditions is empirically analyzed via using non-linear ARDL and ARDL limited test methods.
The empirical findings indicate that in Azerbaijan, military spending aligns with the Military-led Standard of Living Improvement Hypothesis, whereas its positive effect on well-being in Armenia is minimal. Specifically, military expenditure positively influences the standard of living and well-being in Azerbaijan, as evidenced by both the ARDL Bound and multiplier effect. Conversely, according to the Military Burden Hypothesis, military spending poses a burden on the budgets of both countries. Nevertheless, this burden is more pronounced for Azerbaijan compared to Armenia, where the adverse impact of military expenditure is comparatively lesser.

The presence of glomerular diseases in pregnancy presents challenges to both patients and nephrologists. The preconception planning in patients with kidney disease involves comprehensive stratification, treatment optimization, and comorbidity assessment, requiring nephrologists to engage in well-informed decision-making processes alongside their patients. There is a necessity for a multidisciplinary approach to meet their complex healthcare needs. Effective control of blood pressure, proteinuria, and disease activity are pivotal in mitigating adverse pregnancy events. This comprehensive review intends to equip nephrologists with the requisite knowledge and understanding to navigate the intricate landscape of glomerular diseases in pregnancy. It delves into the challenges associated with the diagnosis of glomerular diseases, the significance of preconception counseling, and the nuances of antenatal and postnatal care. Additionally, the article provides insights into the management and prognosis of glomerular diseases, shedding light on the judicious use of immunosuppression as a therapeutic tool.

Background

Several cases of glomerular diseases following Covid-19 vaccination, especially mRNA vaccines, have been reported. However, there is little data on glomerular diseases associated with the two vaccines widely available in India (Covaxin and Covishield) and their long-term outcomes.

Materials and Methods

This was a prospective observational study conducted between May 2021 and May 2023. Patients with new-onset or relapse of proteinuria, hematuria, or renal failure within 30 days of Covid-19 vaccination were included. Data on pre-existing renal disease, vaccine type, symptomatology, laboratory reports, kidney biopsy findings, and treatment details were collected. The clinical course and long-term renal outcomes were studied.

Results

Sixteen patients with Covid-19 vaccine associated glomerular disease (CVAGD) were studied. The median age was 28 years (IQR 20.5–40) and median time of symptom onset was 14 days (IQR 10–16.5) after vaccination. Renal syndromes at presentation were nephrotic syndrome in seven patients (43.75%), nephritic syndrome in seven patients (43.75%), and rapidly progressive renal failure in two patients (12.5%). Kidney biopsy revealed minimal change disease in five patients (31.2%); IgA nephropathy in four patients (25%); C3 glomerulopathy, lupus nephritis, and focal segmental glomerulosclerosis in two patients each (12.5%); and pauci-immune glomerulonephritis (ANCA-associated vasculitis) in one patient (6.25%). Eleven patients were treated with immunosuppressive drugs. Median duration of follow-up was 20 months (IQR 18–21). At last follow-up, 11 patients had complete recovery of renal failure and proteinuria and 4 patients had partial recovery.

Conclusion

The most common lesions in this series were minimal change disease and IgA nephropathy. The overall long-term outcome of CVAGD appears good.

Introduction:

Intertrochanteric fracture is one of the most common fractures of the hip. However, the implant of choice for type II intertrochanteric fracture is still under debate. The aim of this study was to compare the functional outcomes of proximal femoral nail (PFN) and dynamic hip screw (DHS) in treatment of intertrochanteric fractures.

Material and Methods:

We did a prospective comparative study on 60 patients of type II intertrochanteric fractures operated with closed/open reduction and internal fixation with either DHS or PFN between October 2018 and March 2023. During each follow-up, the functional outcome of patients was calculated using the Harris hip score.

Results:

There was a statistically significant difference present in average functional scores between the two groups at 1 month, 3 months and 6 months; however, no difference was seen at the end of 12th month follow-up. Functional outcomes in the DHS group were excellent in 34.78%, fair in 17.39%, good in 43.48% and poor in 4.35%. In the PFN group, results were excellent in 56.52%, fair in 8.70% and good in 34.78% and no poor results were seen.

Conclusion:

In stable two-part intertrochanteric femur fractures, both PFN and DHS are equally effective but due to minimal invasiveness. PFN is a better implant of choice than DHS in the treatment of elderly patients with intertrochanteric fractures.

В статье рассмотрен способ обратной промывки рулонных мембран, который на сегодняшний день считается одним из перспективных. Принцип обратной промывки мембран заключается в снижении рабочего давления установки путем снижения оборотов электродвигателя подающего насоса или его выключения, вследствие чего продукт из резервуара начинает двигаться обратно от центральной части мембраны на ее периферию, смывая накопленные загрязнения изнутри. Приведена математическая модель процесса прямого осмоса продукта из внутренней части мембраны в ее периферийные области. Отдельно описано разбавление потоком продукта на первой стадии слоя с высокой концентрацией солей в приповерхностном слое мембран, а на второй - снижение концентрации солей во всем объеме мембраны при продолжении односторонней осмотической диффузии продукта. Корректность предложенной модели была проверена путем постановки экспериментов над реальной обратноосмотической мембраной рулонного типа. После ряда экспериментов подтверждена справедливость гипотезы о двухэтапном процессе миграции продукта из центра мембраны на ее периферию. Помимо экспериментального подтверждения модели, также изучено влияние концентрации соли в исходной воде во время процесса обратного осмоса на параметры обратной промывки продуктом.

A promising way of back washing of spiral membranes is considered in the article. The principle of backwashing the membranes is to reduce the working pressure of the installation by reducing the speed of the electric motor of the feed pump or turning it off. The product from the reservoir starts to move back from the central part of the membrane to its periphery, washing away the accumulated pollution from the inside. A mathematical model of the process of direct osmosis of the product from the inside of the membrane to its peripheral regions is given. In the first stage, the product dilutes the layer with a high concentration of salts in the near-surface layer of the membranes, while the second reduces the concentration of salts throughout the entire volume of the membrane. The correctness of the proposed model was verified by setting up experiments on a real reverse osmosis membrane of a roll type. After a number of experiments, the hypothesis of a two-stage process of migration of the product from the center of the membrane to its periphery was confirmed. In addition to experimental confirmation of the model, the influence of salt concentration in the initial water during the reverse osmosis process on the parameters of backwashing with the product was also studied.

The article deals with the modeling and management of traffic flow depending on the current road situation. The relevance of the study is due to the daily growth of the vehicle fleet and, as a result, the emergence of congestion. The analysis of automated traffic control systems and traffic flow control technologies is carried out. The algorithms of adaptive control of traffic light objects are considered. A combined method of adaptive traffic control based on the method of queue separation and the method of gap search is proposed. This method is developed for implementation in intelligent adaptive traffic management system. The application of the proposed method allows to manage the existing road network taking into account its density and capacity. A mathematical model of identifying patterns in the flow of moving objects is constructed. The application of this model is aimed at reducing the likelihood of congestion on controlled road sections. Simulation modeling of the proposed method and method with preset phase values of the traffic light object is performed. The efficiency of using the combined method implementing an adaptive model of installation of phases of traffic lights, both at high and low traffic load is proved.
