نشأة النزعة الاستيطانية في الفكر اليهودي العربي خلال القرن 19.
Authors: أمين محمود
Published: June 2024

تعالج هذه الدراسة نشأة النزعة الاستيطانية في الفكر اليهودي الغربي قبل مجيء هرتزل . وتعتمد الدراسة في ذلك على آراء ثلاثة مفكرين كان لهم دور أساسي في نمو هذه النزعة وهم : يهودا القلعي وتسفي كاليشر وموزس هس . وتشير آراء هؤلاء المفكرين أن المصدر الحقيقي لفكرة الصهيونية كانت الرأسمالية الأوروبية لاسيما في بريطانيا وفرنسا ، وأن البرجوازية اليهودية قد تبنت ، في مرحلة لاحقة ، هذه الفكرة ، بعد أن أدركت المكاسب التي يمكن أن تجنيها من وراء تنفيذها ، الأمر الذي شرع يتحقق من التحالف بين الإمبريالية الغربية والبرجوازية اليهودية وذلك حين أخذ دعاة الفكرة الصهيونية من بين كوادر المفكرين اليهود ، ينشرون الفكرة ويدعون لها ، ويعرضون المشروعات المختلفة وبخاصة بين الفئات اليهودية الفقيرة ، وإن ظلت حركاتهم مقيدة دائما بالأطر العامة التي حددتها لهم القوتان المتحالفتان : الإمبريالية الغربية والبرجوازية اليهودية .

Modeling the interaction of the rear cut-out discs of a forest disc plow with the soil when working in clearings
Authors: Knyazev Aleksandr
Published: June 2024

The paper provides an overview of studies of the working processes of disk working bodies of technological machines that provide soil cultivation at different stages of agriculture and forestry. The used designs of forest disk tillage implement have significant disadvantages, namely, insufficient depth of the disks, which results in soil cultivation of insufficient quality, as well as high dynamic loads when encountering various obstacles, which reduce the resource of the unit. The objective of the presented research is to improve the working processes of forestry disc plows by analyzing the properties of hydraulically driven cut-out discs in order to increase their efficiency. A mathematical model of a disk working body with hydraulically driven rear discs with cutouts for strip tillage in forest, root-saturated conditions has been developed. The maximum pressure values of the working fluid in the hydraulic system have been identified. When the angle of attack of the spherical disks changes from 0 to 300, the pressure of the working fluid decreases by 23%. With a further increase in the angle of attack to 450, the pressure of the working fluid increases by 15%, which indicates a nonlinear dependence of these parameters. The maximum traction resistance increases when the angle of attack of the spherical disk changes from 0 to 300 and increases by 29%, and after changing the angle of attack to 450 it increases by 11%. Using the derived formulas, it is possible to approximately determine the kinematic and dynamic parameters of disk working bodies that have cutouts on the cutting surface of the disk.
Using Support Vector Machine for Determining the Need for Artificial Watering Based on the Chlorophyll Fluorescence Induction
Authors: Hrusha Volodymyr
Published: June 2024

Introduction. Chlorophyll fluorescence induction (CFI) is a method for receiving additional information about state of plants without its injuring. CFI occurs when the plant is illuminated in the blue spectrum of light. The so-called Kautsky curve in the red spectrum of light is measuring. Currently, there are scientific papers about determining water deficit using CFI and neural networks. Support Vector Machin (SVM) – the model of machine learning capable of performing linear or non-linear classification, regression and even finding outliers in data. SVM can be an alternative to neural networks for analysis of CFI measurements.
The purpose of the paper is to assess the possibility of determining the need for artificial watering of soybean plants based on the SVM and compare the results with the results obtained by the author in earlier experiments of analyzing the CFI of zinnia plants.
Results. SVM research was conducted using different SVM kernels, different methods of normalizing CFI measurements, different methods of the dimensionality reduction of CFI data. The SVM implementation from the Scikit-learn Python library, the SVR (Support Vector Regression) class was used. The best kernel of SVM, the best normalization method, and the best method of forming the input vector for the support vector machine were experimentally revealed for determining the need of artificial watering.
Conclusions. The research of Support Vector Machine for the purpose of determining the need for artificial watering based on CFI curves were conducted. The research showed that the best result is obtained (1) using a polynomial kernel of the fourth degree, (2) using 10 points of CFI curve taken unevenly on an exponentiation scale (power of 1/8), (3) using minimax normalization of CFI measurements. SVM showed a worse result in the analysis of CFI curves of soybean plants than in the analysis of CFI curves of the zinnia plants. It can be explained by the fact that the soybean is a drought resistant plant and therefore CFI demonstrated worse a moisture deficit. Keywords: Support Vector Machine, chlorophyll fluorescence induction, dimensionality reduction of data.

Aim. To present our own experience in treating patients with chronic lymphocytic leukemia (CLL) during the COVID-19 pandemic.

Materials and methods. The first group included 20 patients receiving therapy according to the FCR (fludarabine, cyclophosphamide, rituximab) – 15 people and RB (rituximab and bendamustine) – 5 people. The second group consisted of 10 patients receiving ibrutinib at a dose of 420 mg/day continuously.

Results. Both groups of CLL patients showed a high incidence of COVID-19 associated pneumonia (90 and 80% respectively for groups 1 and 2, p=0.06) and a severe course of pneumonia (84% in patients of group 1 and 66.7% in patients of group 2, p=0.0052). At the same time, none of the patients receiving ibrutinib therapy required mechanical ventilation. Among the patients receiving rituximab therapy, mechanical ventilation was required in 10 cases. Among the patients in group 1, the mortality rate was 55.5%. Among the patients receiving ibrutinib therapy, no deaths due to pneumonia or progression of hematoblastosis were registered.

Conclusion. Bruton's tyrosine kinase inhibitors are the safest and most effective in treating patients with CLL during the COVID-19 pandemic. This is due to the immunomodulatory action of ibrutinib; a higher likelihood of achieving a complete response compared to patients receiving FCR and RB protocols; the possibility of outpatient treatment and minimizing the need to visit medical facilities.

Authors: Kutepova O. L. , Andrievskaya I. A.
Published: June 2024

Aim. This study aimed to evaluate red blood cell indices and examine erythrocyte morphology in pregnant women with mild to moderate COVID-19 during their third trimester.

Materials and methods. A total of 85 pregnant women who underwent COVID-19 in the third trimester of pregnancy were examined, of whom 44 had a mild course (Group 1) and 41 had a moderate course (Group 2) of the disease. A control group included 35 non-infected pregnant women. The total erythrocyte and hemoglobin counts were assessed, along with hematocrit levels using an automated hematology analyzer, and the morphological shapes of erythrocytes were evaluated using the "MEKOS-C2" automated microscopy system. Erythrocyte transformation indices were also calculated.

Results. The COVID-19 course severity-dependent decrease in the total number of erythrocytes, hemoglobin and hematocrit in the blood of pregnant women relative to the control group was determined. Cytometric analysis of blood smears indicate a reduction in discocyte content in both the mild and moderate COVID-19 groups, both relative to the control and within the groups. Increased numbers of echinocytes and platecytes were observed in both groups compared to controls. In cases with moderate disease severity, increases in elliptocytes, dacryocytes, and degenerative erythrocyte forms were noted. These alterations led to heightened poikilocytosis indices in pregnant women with COVID-19 compared to controls and between groups. The levels of anisocytosis and polychromatophilic erythrocytes did not change significantly. The development of anisochromia was noted in the moderate disease group. Transformation indices for both reversible and irreversible changes were elevated in groups 1 and 2.

Conclusion. The moderate COVID-19 in the third trimester of pregnancy compared to the mild course of the disease is associated with more pronounced changes in the red blood system, characterized by a decrease in the number of erythrocytes and hemoglobin, the development of anisochromia and poikilocytosis. indicating anemia whose severity correlates with the severity of COVID-19 among pregnant women.

This study sought to determine the effect of modelling approach, on the hygiene and sanitation of the school. Eventually, it also sought to determine the magnitude of effect of the action initiated by the researcher on the class participation of the research subjects. This study made use of the quasi-experimental research design which was a non-equivalent control group pretest-posttest design. Non-equivalent design was a good design when the researcher had access to one group for experimentation (Vockel 2019). The researcher opted to use this design because the subjects of the study were intact group of learners. This study will be conducted in Apolonio Fuentes Sr. Elementary School, Hagonoy 1 District Division of Davao Del Sur. The subjects of this study will be the 95 grade six pupils – 47 are from section A which will be the controlled group and 48 are from section B which will be the experimental group. The composition of these two sections was homogeneous. Both learners from sections A and B have identical grades. This study made use of the non-random assignment of subjects where all learners of both sections A and B were involved as subjects of the study. This study revealed that the utilization of modelling approach and hygiene and sanitation level of grade 6-Rizal classroom had increased the historical appreciation skills of grade six pupils. It also revealed that there was magnitude of difference between the post test scores of the controlled and experimental groups.

A review of papers on the use of the EDR (eddy dissipation rate) parameter in meteorological aviation service is presented. EDR is associated with the rate of dissipation of turbulent kinetic energy and is the cube root of its value. The EDR characteristic, independent of an aircraft type, has been designated by ICAO as the measure for determining turbulence intensity. The physical basis of the EDR application, methods for determining EDR in situ and in the surface layer of the atmosphere using remote sensing are discussed. Some approaches to forecasting turbulence in EDR units in numerical weather prediction models are considered

Authors: Al Horr Yousef , Alkhalaf Qusai
Published: June 2024

The manufacturing of closed impellers via Laser Powder Bed Fusion technology entails inherent complexities, demanding meticulous attention to support structure design, determination of building angle, and down-skin energy density to ensure successful production. This study explores the use of stainless steel 316L in fabricating closed impellers using LPBF. The aim is to investigate the impact of process parameters and building angles on impeller fabrication quality. In addition to studying the effect of energy density on the surface roughness and hardness values of the impeller. The investigation examines building angles of 0˚, 30˚, and 90˚ for a closed impeller, revealing that a 30˚ building angle yields successful printed parts. Moreover, to achieve defect-free closed impellers, it is imperative to maintain down-skin energy density between 80% and 100% of in-skin energy density. The maximum hardness and minimum surface roughness were recorded at 233 HV and 12.79 µm, respectively, when the energy density was 41.66 J/mm³ and 55.55 J/mm³ respectively.  The novelty of this study lies in the fabrication of closed impellers using stainless steel 316L through laser powder bed fusion.

Published: June 2024

Monoalkyl carbonates (MACs) or, more broadly, hemiesters of carbonic acid (HECAs), constitute a class of compounds that are omnipresent in our lives, once formed by the reaction of carbon dioxide with alcohols. Despite their commonness, MACs are elusive in solution and went largely unnoticed by most researchers until the recent resurgence of interest in studying their properties, relevance (e.g., in CO2 capture), and analysis (for example, in foods, drinks, and sugars), by using techniques like NMR, MS, and CE. This literature review, spanning almost two centuries, sheds light on the importance of the chemistry of MACs. Their subtle formation can be responsible for significant changes in the charge and electronic characteristics of compounds with an alcohol functional group, altering properties such as solubility, polarity, diffusion coefficient, and conductivity. Such changes in properties lead to the hypothesis that MAC formation may play an important role also in the biological environment, including membrane transport. Many questions remain open in the rich emerging research field of the chemistry of MACs, and better understanding is essential for advancing the knowledge of these ubiquitous compounds and their potential impact on various processes and products.

Published: June 2024

Encapsulation is a pivotal technique for protecting and enhancing the efficiency of sensitive natural bioactive substances, notably essential oils, vitamins, and phenolic compounds, widely used in foods and nutraceuticals. Critical considerations in selecting encapsulation agents encompass safety, release kinetics, stability, and cost-effectiveness. Yeast cells emerge as versatile carriers distinguished by their low cost, compatibility with biological systems, and eco-friendly degradation properties, accommodating both hydrophilic and hydrophobic bioactive agents. Various yeast strains, including Saccharomyces cerevisiae, Torulopsis lipofera, Cutaneotrichosporon curvatus, Yarrowia lipolytica, and Candida utilis, find utility in microencapsulation. Yeast cell encapsulation relies on the permeation of bioactive agents through yeast cell walls, predominantly composed of mannoproteins and polysaccharides. The encapsulation process includes passive or vacuum-infused diffusion of bioactive compounds inside yeast cells, precise droplet size control, and attractive forces to trap bioactive components within cellular structures. Yeast cells display versatility in various states, whether alive or dead, intact or plasmolyzed. In addition, the loading capacity of hydrophobic bioactives can be increased through chemical pretreatment techniques such as plasmolysis, autolysis, and enzyme hydrolysis, freeing up space within yeast cells by eliminating water-soluble components. In summary, yeast cell encapsulation presents a promising and sustainable technology with diverse applications within the food industry. Yeast cells enhance the stability and controlled release of bioactive compounds, magnifying the efficacy of natural hydrophobic bioactives like curcumin, essential oils, β-carotene, and vitamin D across various food products. This comprehensive review focuses on the encapsulation procedures, influential factors, characterization techniques, and applications, with a pronounced emphasis on hydrophobic materials.

Published: June 2024

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a hepatic manifestation of the metabolic syndrome. It is one of the most common liver diseases worldwide and shows increasing prevalence rates in most countries. MAFLD is a progressive disease with the most severe cases presenting as advanced fibrosis or cirrhosis with an increased risk of hepatocellular carcinoma. Gut microbiota play a significant role in the pathogenesis and progression of MAFLD by disrupting the gut-liver axis. The mechanisms involved in maintaining gut-liver axis homeostasis are complex. One critical aspect involves preserving an appropriate intestinal barrier permeability and levels of intestinal lumen metabolites to ensure gut-liver axis functionality. An increase in intestinal barrier permeability induces metabolic endotoxemia that leads to steatohepatitis. Moreover, alterations in the absorption of various metabolites can affect liver metabolism and induce liver steatosis and fibrosis. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are a class of drugs developed for the treatment of type 2 diabetes mellitus. They are also commonly used to combat obesity and have been proven to be effective in reversing hepatic steatosis. The mechanisms reported to be involved in this effect include an improved regulation of glycemia, reduced lipid synthesis, β-oxidation of free fatty acids, and induction of autophagy in hepatic cells. Recently, multiple peptide receptor agonists have been introduced and are expected to increase the effectiveness of the treatment. A modulation of gut microbiota has also been observed with the use of these drugs that may contribute to the amelioration of MAFLD. This review presents the current understanding of the role of the gut-liver axis in the development of MAFLD and use of members of the GLP-1 RA family as pleiotropic agents in the treatment of MAFLD.

BACKGROUND

Gastric cancer (GC) is the most common malignant tumor and ranks third for cancer-related deaths among the worldwide. The disease poses a serious public health problem in China, ranking fifth for incidence and third for mortality. Knowledge of the invasive depth of the tumor is vital to treatment decisions.

AIM

To evaluate the diagnostic performance of double contrast-enhanced ultrasonography (DCEUS) for preoperative T staging in patients with GC by comparing with multi-detector computed tomography (MDCT).

METHODS

This single prospective study enrolled patients with GC confirmed by preoperative gastroscopy from July 2021 to March 2023. Patients underwent DCEUS, including US and intravenous CEUS, and MDCT examinations for the assessment of preoperative T staging. Features of GC were identified on DCEUS and criteria developed to evaluate T staging according to the 8th edition of AJCC cancer staging manual. The diagnostic performance of DCEUS was evaluated by comparing it with that of MDCT and surgical-pathological findings were considered as the gold standard.

RESULTS

A total of 229 patients with GC (80 T1, 33 T2, 59 T3 and 57 T4) were included. Overall accuracies were 86.9% for DCEUS and 61.1% for MDCT (P < 0.001). DCEUS was superior to MDCT for T1 (92.5% vs 70.0%, P < 0.001), T2 (72.7% vs 51.5%, P = 0.041), T3 (86.4% vs 45.8%, P < 0.001) and T4 (87.7% vs 70.2%, P = 0.022) staging of GC.

CONCLUSION

DCEUS improved the diagnostic accuracy of preoperative T staging in patients with GC compared with MDCT, and constitutes a promising imaging modality for preoperative evaluation of GC to aid individualized treatment decision-making.
