Marketing channels, marketing margins, efficiency and elasticity of marketing price transmission for white pepper in Sambas Regency will be the objectives of this research. Quantitative descriptive methods were used in this research. Non-probability sampling is a technique used with the purposive sampling method. Primary and secondary sources are the data used. Marketing margin analysis, marketing channel efficiency, and price transmission elasticity are some of the methods used. The results of this research show that there are two different marketing channels for white pepper in Sambas Regency: channel I directly from farmers to wholesalers then to final consumers, and channel II from farmers to collectors then to wholesalers then to final consumers. Channel I marketing efficiency is 0.46% and farmer's share is 97.56%, resulting in a marketing margin of IDR 2,000/kg. At the same time, marketing channel II achieved a marketing margin of Rp. 5,000/Kg, with a farmer's share of 93.90% and a marketing efficiency level of 0.83%. Marketing channel I is more efficient than marketing channel II. The elasticity value of price transmission in channel II is 0.663, which means that every 1% change in consumer prices will cause a change of less than 1% or 0.663% change in producer prices so it is inelastic. On the other hand, the collector level and producer level have an elasticity value of 0.632, meaning that a 1% change at the collector level results in a price change of 0.632% or less than 1% at the producer level (Inelastic). Thus, the influence of consumer prices is greater than collector prices.

Authors: Aldahadha Basim
Published: July 2024

A Muslim usually prays 5 times a day, is obligatory for every Muslim. Prayer includes many movements and postures, and measure of reverence in Muslim prayer (MRMP) is an essential part of accepting this practice. This study aimed to explore the effectiveness of MRMP on some cardiovascular responses (CRs). The study sample consisted of 74 students (36 = males, 38= females) with ages ranging from 18 to 20 years (M = 19.44, SD = 0.74). The participants were from Jadara University (Jordan) and were selected according to the degree of their responses to both sides of MRMP. They were divided into two groups: a high MRMP group (N = 37), who obtained the highest scores on the MRMP scale, and a low MRMP group (N= 37), who had the lowest scores on MRMP. The high MRMP group was trained on the items     of MRMP and reminded of them, while the low MRMP group did not receive any kind of training. The results showed that there was a decrease in the after measurements of pulse (F = 12.326, p = 0.001), systolic blood pressure (F = 30.331, p = 0.001) and diastolic blood pressure (F = 18.375, p = 0.001), while the results did not show an effect on the oxygen level. The results did not show an effect of sex, nor an interaction between group and sex. The results of this study supported the importance of MRMP and its positive impact on the health of the body, the circulatory system, and heart health as a result of mental health.

The clarity of vocational identity is an important focus of professional guidance since it is related to many factors, such as career thoughts and psychological well-being. This study examines the relationship between vocational identity, psychological well-being and career thoughts among students at Hashemite University in Jordan, as well as any gender or faculty specific differences in vocational identity, psychological well-being and career thoughts. Randomly selected male and female students (n= 680) aged 18 to 22 completed questionnaires on vocational identity, psychological well-being, and career thoughts. There was a positive correlation between vocational identity and psychological well-being, and its subscales (autonomy, environmental mastery, personal growth, positive relationship, purpose in life, and self-acceptance), but a negative correlation between vocational identity and career thoughts and between vocational identity and career thoughts subscales (decision-making confusion, commitment anxiety, and external conflict). Additionally, there were statistically significant differences in the levels of vocational identity by gender, with males favoured but not by faculty. Finally, variables related to gender and faculty had no significant effect on psychological well-being or career thoughts. The results confirm a positive correlation between vocational identity and psychological well-being but a negative correlation between vocational identity and career thoughts. The results also confirm the level of vocational identity among male students was higher than that of female students. The results of this study can be used in the counseling and career guidance process for university students.

Authors: Mohammed Noor A.
Published: July 2024

Herbal and dietary supplements are commonly used throughout the world; these unlicensed supplements are not recommended due to concerns about their clinical efficacy and safety. Adios are marketed for weight loss in Iraq and many other countries and are commonly used by women.      The safety of these weight loss aids is unknown. This study aimed to evaluate adios adverse effects by conducting biochemical, hematological, and histological examinations on the liver and kidney. Rats were orally administrated for 30 days with different concentrations of adios supplements (0.001g/100g), (0.002g/100g), and (0.003g/100g) as low (LD) medium (MD) and high (HD) concentrations, respectively. The results showed no weight loss in rats over 30 days across experiments in all the treated groups (LD, MD, and HD) compared to the control. Adios showed significant differences between the control and the treated concentrations in the following hematological parameters: white blood cells (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), lymphocyte (LYM), and red cell distribution width (RDW) in a dose-dependent pattern. Furthermore, there were various alteration in the histopathological examination of the kidney and liver. From the current data, it can be concluded that adios has zero efficacy in weight loss and is not recommended for use because it has adverse effects on many hematological and biochemical parameters and with obvious pathological changes in both the kidney and liver.

Published: July 2024

В работе рассматривается одна из основных задач при разработке интерпретатора для инструментария BlockSet – проектирование синтеза SQL запросов на основе метамодели, а так программного обеспечения для его применения. Авторами рассмотрен как инструментарий в целом, так и роль самого алгоритма в его контексте. Подробно рассмотрены периферийные инструменты для управления алгоритмом в разках языка BML. Продемонстрированы этапы его формирования и технические тонкости реализации. Помимо прямого алгоритма так же рассмотрен обратный алгоритм генерации запроса для поиска факторов частных событий, который необходим при реализации ресурса на основе событийно-ориентированного подхода. Для наглядности разобран пример обработки события появления “сообщения”, в результате которого необходимо определять id “пользователей” -- отправителя и получателя, которых нужно уведомить о появлении указанного “сообщения”. Подведены выводы, демонстрирующие, результаты проделанной работы.

The paper examines one of the main tasks in developing an interpreter for the BlockSet toolkit - designing the synthesis of SQL queries based on the metamodel, as well as software for its use. The authors examined both the toolkit as a whole and the role of the algorithm itself in its context. Peripheral tools for managing the algorithm in the BML language are discussed in detail. The stages of its formation and technical details of implementation are demonstrated. In addition to the direct algorithm, a reverse algorithm for generating a query to search for factors of private events, which is necessary when implementing a resource based on an event-oriented approach, is also considered. For clarity, an example of processing the “message” event has been analyzed, as a result of which it is necessary to determine the id of “users” - the sender and the recipient, who need to be notified about the appearance of the specified “message”. Conclusions are drawn demonstrating the results of the work done.

MULTIHEURISTIC APPROACH TO COMPARE THE QUALITY OF DEFINED METRICS ON THE SET OF DNA SEQUENCES
Authors: Мельников Б.Ф. , Пивнева С.В. , Трифонов М.А.
Published: July 2024

В настоящей статье анализируется несколько метрик, определяющих различия в последовательностях ДНК разных видов. Рассматриваются несколько стандартных метрик, а также модификация оригинальной авторской метрики, предыдущие версии которой рассматривались в наших прежних публикациях. При определении качества метрик мы исходим из предположения о том, что для любых трёх далёких видов вычисляемые по этой метрике расстояния между ними должны образовывать треугольник, близкий к равнобедренному остроугольному. Мы считаем несколько вариантов отклонения треугольника от равнобедренного остроугольного, после чего считаем сумму таких отклонений для всех получающихся треугольников. На основании проведённых подсчётов делаем вывод о качестве первоначальных метрик. После этих вычислений применяем полученную методику к рассмотрению этих же метрик для близких видов (человекообразных обезьян и человека) - и на этих близких видах получаем немного иные результаты сравнительного анализа рассматриваемых метрик.

In this article, we analyzed some several metrics that determine the differences in DNA sequences of different species. Several standard metrics are considered, as well as a modification of the original author's metric, the previous versions of which were considered in our previous publications. Determining the quality of some several metrics, we proceed from the assumption that for any three distant species, the distances between them computed from this metric should form a triangle close to an isosceles acute-angled triangle. We consider several variants of the deviation of a triangle from an isosceles acute-angled triangle, and then we consider the sum of such deviations for all the resulting triangles. Based on these calculations, we make a conclusion about the quality of the original metrics. After these calculations, we apply the obtained technique to the consideration of the same metrics for close species (anthropoid and human), and on these closely related species, we obtain slightly different results of a comparative analysis of the metrics under consideration.

The development of an emergency control system for a pumping station of the second lift has been described. The HMI-interface for the touch graphic operator panel of the Weintek company has been designed in the EasyBuilder Pro software environment. The HMI-interface displays the pumping station's circuit diagram, and also allows to select the image of control elements, monitoring windows and the color scheme of individual interface elements. The functional purposes of the screens have been disclosed: control, current events and archives of the pumping station, graphics, settings and operating time of pumping units. The algorithm of operation of an automated control system implemented on the basis of a programmable logic controller Axioline from Phoenix Contact has been described. The main advantage of this control system is the ability to maintain a given pressure in the pipeline and ensure a stable water supply in conditions of uneven consumption. At the same time, the system fully meets the specified reliability conditions and provides protection for pumping units from various emergency situations. In addition, a friendly HMI interface has been implemented, which makes it possible to train duty and operational personnel in a short time.

Подшипники энергетических паровых турбоустановок фиксируют положение ротора в радиальном и осевом направлениях и должны выдерживать высокие нагрузки, работать на высоких скоростях, что влияет на надежность установки и электростанции в целом. Поэтому рассмотренные проблемы контроля состояния подшипников скольжения в данной статье крайне важны. Практика показывает, что диагностика даже незначительных изменений в состоянии подшипников, вызванных износом, нарушениями в смазке или тепловыми воздействиями, все еще неудовлетворительна. В данной работе представлены результаты исследований, которые показывают, что анализ акустической эмиссии позволяет с высокой точностью диагностировать изменения в работе подшипников скольжения. Исследования проводились с целью усовершенствования методов диагностики для мониторинга паровых турбин тепловых электростанций.

Bearings of power steam turbine units fix the position of the rotor in the radial and axial directions and must withstand high loads, operate at high speeds, which affects the reliability of the installation and the power plant as a whole. Therefore, the problems of monitoring the condition of sliding bearings considered in this article are extremely important. However, practice shows that the diagnosis of even minor changes in the condition of bearings caused by wear, lubrication problems or thermal effects is still unsatisfactory. This paper presents the results of studies that show that the analysis of acoustic emission makes it possible to diagnose changes in the operation of sliding bearings with high accuracy. The research was carried out in order to improve diagnostic methods for monitoring steam turbines of thermal power plants.

За последние годы обстановка в околоземном космическом пространстве характеризуется существенным увеличением как количества запусков ракет-носителей, так и количества космических аппаратов в каждом запуске. Следовательно, также увеличивается и объем информации, поступающей в вычислительный комплекс автоматизированной системы мониторинга космического пространства, что приводит к задержкам ее обработки. Особенно критичным становится достижение требуемых значений показателя оперативности при выполнении задачи обнаружения и выдачи информации об опасных сближениях космических аппаратов. Возникает необходимость совершенствования методики организации оперативной обработки поступающей информации с учетом ее качества в условиях априорной неопределенности возрастания вычислительной нагрузки.

In recent years, both the number of launch vehicles and the number of spacecraft in each launch have increased signi cantly. Consequently, the volume of information entering the computer complex of the automated space monitoring system has also increased, which leads to delays in its processing. It becomes especially critical to achieve the required values of the ef ciency indicator when performing detection tasks, determining the class and type of space objects. There is a need to develop and apply a methodology for organizing operational processing of incoming information, taking into account quality in conditions of a priori uncertainty of increasing computational load.

Элегантность и эффективность применения полиномов Цернике главным образом обусловлена их ортогональностью, а их недостатки обусловлены двухмерностью полиномов, что не позволяло их применять в общем случае представления аберрационных функций. В представленной статье сформированы четырехмерные ортогональные полиномы, обеспечивающие разложение волновой аберрации в четырехмерной области поле зрения - светосила. Это позволило сформировать теорию ортогональных аберраций и получить мощный инструмент по повышению эффективности проектирования оптических систем.

The elegance and ef ciency of using Zernike polynomials is mainly due to their orthogonality, and their disadvantages are due to the two-dimensionality of the polynomials, which did not allow them to be used in the general case of representing aberration functions. In this article, four-dimensional orthogonal polynomials are formed that provide the decomposition of wave aberration in the four-dimensional eld of view - aperture region. This made it possible to formulate the theory of orthogonal aberrations and obtain a powerful tool for increasing the ef ciency of design of optical systems.
