Published: October 2023

Palm oil plantations have the potency to provide forage as a source of energy for livestock. The objective of this research was to estimate the production and quality of weeds under palm plantation as ruminant feed. Identification was conducted to find out information about botanical composition, production and nutritional content to estimate potential forage. The study was conducted using a randomized block design with 2 blocks of 6- and 8-years old palm and 10 sample plots. The research parameters were botanical composition, weed dominance and diversity, and also forage production potency. The results showed that 19 species from 11 families were found and dominated by gramineae. The weed botanical composition and diversity level was affected by oil palm plantation age. On the 8 years old oil palm plantation, the number of weed species and diversity level were decreased, reaching 10 species and H’ 2.41 while on the 6 years old were 13 species and H’ 3.14. Based on the type of weed, Paspalum conjugatum P.J. Bergius is a weed that has the potential to be used as the highest forage as ruminant animal feed with an estimated production of 730.42 kg ha-1 of fresh biomash. The estimation of weed production ruminant forage was dominated by grass that had up to 1.87 ton ha-1 of fresh biomash.

Impact of soil composition on maximum depth of wetting in expansive soils
Authors: Alnmr Ammar 
Published: October 2023

AbstractExpansive unsaturated soils present challenges in construction due to their moisture-induced behavior. This study proposes empirical equations to estimate the maximum wetting depth over time. Laboratory experiments and numerical analyses using SEEP/W software investigate wetting depth considering time and sand content in coastal and inland regions. Results reveal the significant influence of sand content on maximum soil moisture depth, emphasizing a recommended content above 30% to mitigate heave. The equations offer practical tools for assessing wetting depth, accounting for temporal and spatial variations. This research highlights the importance of wetting depth in addressing soil-related concerns and provides a foundation for further exploration of related factors.
Hysteresis damping ratio for moment steel frame evaluation using DDBD
Authors: Sultan Hussein Kareem 
Published: October 2023

AbstractThe main purpose of this paper is to propose a model for estimating the hysteresis damping ratio of moment steel frames and compare them with the results obtained using direct displacement-based design. In this study, different models of steel bending frames were examined by using several type of analysis to obtain this ratio. Thirty-steel frame models with 3, 6, 9, 12, and 15 floors and 3 and 6 bay with 6 m span length were analyzed and evaluated. The results showed that the equivalent damping ratio at the level of safety based on Jacobsen and Jennings, and the values of the equivalent damping relationships according to FEMA-440 vary from the empirical formula proposed in displacement-based design-2012. Therefore, in the ductility domain the exponential relationship form was more consistent with the results used. A new formula was proposed to calculate the hysteresis damping ratio, and it is more accurate than the empirical formula proposed in displacement-based design-2012.

Background: According to current American Association of Orthodontists guidelines, two-dimensional lateral and posteroanterior cephalometric radiographs are recognized as essential components of diagnostic imaging records in orthodontics. Cephalometry is defined as the discipline that analyzes the craniofacial complex in a segmented way, to study the interrelationships between its structures and understand how the growth or alteration of one of these structures can compromise the whole. Through cephalometry, it is possible to indicate the clinical approach for patients, involving dental therapy with intraoral appliances and physical therapy with continuous positive pressure in the upper airway. Objectives: Investigate possible differences in cephalometric anatomical patterns between genders. Methods: This study protocol follows the STROBE - Strengthening the Reporting of Observational Studies in Epidemiology guidelines. A convenience sample will be used, consisting of teleradiography (cephalograms) of adult patients of both genders, carried out in a private Dental Clinic, located in the city of São José dos Campos (SP), Brazil, by the established inclusion and exclusion criteria. Six angular and nine linear measurements will be used in the analysis of cephalometric measures according to the study protocol. The exams will be distributed into three groups and paired according to the value of the angle formed between point A nasion and point B nasion (ANB). Groups will be formed by exams with class 1 skeletal relationship (0o < ANB angle ≤ 4º), group 2 with class 2 exams (ANB angle > 4°), and group 3 formed by class 3 exams (ANB angle ≤ 0°). Considerations: In some cases, craniofacial changes may predict the risk of sleep-disordered breathing, such as obstructive sleep apnea (OSA). Increased length and thickness of the soft palate and hyoid bone in the mandibular plane and retrognathia are associated with the pathogenesis of OSA. Therefore, the etiology of sleep-disordered breathing may vary in patients according to gender, according to cephalometric analysis.
Military Transformations in Sweden and Norway During the Swedish-Norwegian Conflict on the Turn of the 19th — 20th Centuries (According to the Russian Diplomatic Correspondence)
Authors: Sadova Lyudmila 
Published: October 2023

The arms race that unfolded at the turn of the 19th — 20th centuries in Sweden and Norway coincided with the development of the crisis in Swedish-Norwegian relations. Norway&apos;s struggle within the framework of the union with Sweden to expand its rights and gain greater independence led to an increase in discontent in public and political circles in Sweden, and the increasing pace of modernization of the armed forces of both countries generated mutual suspicions, rumors and accusations of purposeful activities against the “fraternal people”. Relying on the documents of the Archive of the Foreign Policy of the Russian Empire, in particular on the reports of Russian diplomats who carefully observed the course of the conflict and carefully described all the events on the pages of their reports, the question is raised whether it is possible to talk about the Swedish-Norwegian conflict as the main reason for military reforms, whether the measures taken by the two countries were exclusively directed against each other. It can be concluded, to which Norwegian researchers also come, that the military buildup by Sweden and Norway at the turn of the 19th — 20th centuries was the result of a complex of reasons: firstly, it occurred in the context of the pan-European process of strengthening the armament of European states, and secondly, it was closely related to the growth of Norwegian nationalism and was perceived as part of the on national identity, characteristic of that time and thirdly, was in close interaction and influenced by the problems associated with the constitutional crisis of 1890—1905.

The study of regional histotopographic features of the diaphragm in normal conditions and in various types of metastatic lesions is of practical importance in abdominal oncology when planning cytoreductive surgical interventions and diaphragmatic peritonectomy.The aim was to study the histotopographic structure of the diaphragm in normal and peritoneal carcinomatosis.Material and methods. 40 non-embalmed preparations of the cadaveric diaphragm were used to prepare histotopograms of their various parts. The surgical material of 77 patients who underwent cytoreductive intervention and diaphragmatic peritonectomy of various volumes was also studied and histological preparations were made. Regional histotopographic features of the diaphragm in normal and metastatic lesions were studied. A correlation analysis of the size of carcinomatous nodes and the depth of tumor invasion was carried out.Results. It was found that the histotopographic structure in various parts of the diaphragm is normally specific and has a number of differences. Metastatic damage to the diaphragm in peritoneal carcinomatosis differs in size of tumor nodes, in depth of tumor invasion, and in combined lesion of adjacent anatomical structures. In most cases, the size of carcinomatous lesions directly correlated with the depth of tumor invasion, however, it was found that a number of large tumor nodes do not have such a depth of germination, but affect only the superficial layers of the diaphragm (peritoneum and diaphragmatic fascia).Conclusion. The results of studying the depth of tumor invasion, which is often associated with the size of carcinomatous nodes, can be implemented in clinical practice when planning cytoreductive surgical interventions and performing diaphragmatic peritonectomy.
Clinical Aspects of Connexins 37, 40, 43, 45 Expression in the Embryonic and Adult Kidneys

Published: October 2023

Nowdays, there is a wide variety of judgments regarding the specific expression of some forms of connexins (Cx) in the renin apparatus of the embryonic and adult kidneys. Establishing the exact intrarenal localization of Cx 40, 37, 43, 45 is a prerequisite for understanding their functional role in normal renal organogenesis, as well as in maintaining fluid homeostasis and controlling renin secretion. At 8–10 weeks of embryonic development, the expression of various Cx is observed in the epithelium of blood vessels and renal tubules, as well as in the region of the renal renin apparatus, but with different patterns of expression and intensity over time. During embryogenesis, the expression of Cx 40 is higher than that of Cx 43, 37, and 45. In the postnatal period, the expression of Cx 40 decreases, while the expression of others increases. Cx 40 is involved in the formation of the renin apparatus in the developing kidney, while Cx 37, Cx 43, and Cx 45 are involved in signaling important for postnatal maintenance of kidney function and blood pressure control. Knockout Cx 45 is a lethal mutation that leads to impaired differentiation of smooth muscle tissue of arterioles. On the contrary, the deletion of individual genes Cx 37, 40 and 43 has little effect on renal organogenesis, probably due to the redundancy and interchangeability of various connexin isoforms. Experimental studies in the adult kidney demonstrate that arterial endothelial cells express Cx 40 and Cx 37 and, to a lesser extent, Cx 43, while smooth muscle cells express Cx 45. The cells of the renin apparatus are characterized by the expression of Cx 37, Cx 40, Cx 43 and Cx 45, with the highest content of Cx 40, especially in juxtaglomerular cells. Adequate and coordinated work of Cx is crucial for the regulation of renal hemodynamics and renin secretion in nephrology. The use of specific connexin-mimetic peptides may lead to the development of more effective methods for controlling renin secretion.

Published: October 2023

Introduction: Today, the insurance industry is considered one of the most essential factors in wealth and social well-being production. This industry is based on economic service and has a critical and sensitive position in economic growth and development, especially in developing countries. Since human resources are the most valuable capital to realize the goals of this industry, therefore, it is necessary to examine the factors related to the psychological empowerment of employees. Based on this, the current research was conducted to compare the quality of work life and job embeddedness based on the life orientation of optimistic-pessimistic nature in Kermanshah insurance offices.
Methods: This study was a causal-comparative study in terms of goals and descriptive in terms of the data-gathering procedure. The sample size of the research was 280 people (62 women and 218 men) from the employees of Pasargad Insurance in Kermanshah city in 1401, which were selected by convenience sampling. To collect data, Walton's Quality of Work Life (QWL), Ardalan et al.'s Job Embeddedness (JEQ), and Sheyer & Carver's Life Orientation (LOT) questionnaires were used. The research data were analyzed using SPSS-27 software and multivariate analysis of variance.
Results: The results of the MANOVA test showed that all the dimensions of the quality of work life are different based on the life orientation of optimistic-pessimistic nature. This claim is also true about the six components of occupational institutionalization and shows, that the dimensions of job embeddedness are based on the life orientation of optimistic-pessimistic nature have a significant difference.
Conclusion: Optimism as a hopeful expectation in a specific situation can play a significant role in the quality of working life, and the desire to continue working and creating attachment to organizational tasks. As a result, it is suggested that managers prepare training programs for employees to adopt an optimistic orientation in life to reduce job abandonment and attachment to the organization, which is a consequence of job embeddedness.

Introduction: job stress is defined as the accumulation of stressful factors in job-related situations, which most people agree is stressful, and it can be the direct factor in the intention to leave the job. The present study investigates the effectiveness of virtual reality exposure therapy and compares its effectiveness with mindfulness-based stress reduction based on mindfulness on the components of job stress employees with job stress.
Materials and Methods: The research design was a semi-experimental pre and post-test with a control group and a follow-up phase. The statistical population included all employees with job stress in a private company in Isfahan City in 2022, and the research sample included 45 employees who were randomly divided into three groups of 15: virtual reality therapy, mindfulness-based stress reduction therapy, and Controls were replaced. The people of the two intervention groups participated in the intervention sessions; The first experimental group underwent eight 20-minute weekly sessions of virtual reality therapy, and the second experimental group underwent eight weekly 45-minute sessions based on the Kabat-Zin training package (1990 and 2013), but for the control group no interventions were performed. The participants responded to the occupational stress questionnaire of the Health and Safety Institute of England Steinmetz (HSE) (1990) in three stages. The research data were analyzed with analysis of covariance and Bonferroni's post hoc test and using SPSS23 statistical software at two descriptive and inferential levels.
Results: The results of covariance analysis and Bonferroni's post hoc test indicated that both intervention methods equally and effectively reduced occupational stress in the fields of role, communication, support of colleagues, changes in employees, and the effect of both interventions remained stable over time (P<0.01). Although both methods of intervention reduced the pressure and job stress of employees, and the components of stress include support, control, and demand from officials, and its effect remained constant over time, virtual reality treatment was more effective in both stages (P>0.05).
Conclusion: The results showed that virtual reality courses and stress reduction based on mindfulness can reduce the tensions and job stress of personnel and employees of organizations.
