Determining the best cutting mode is a common problem for machining processes as well as for CBN (Cubic Boron Nitride) grinding on Computer Numerical Control (CNC) machines. It is even more important when it is necessary to choose a solution that meets many goals, which are in conflict. This paper presents the results of a multi-criteria decision-making (MCDM) study on CBN grinding of cylindrical-shaped parts on CNC milling machines. Three MCDM methods, including TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution), MAIRCA (Multi-Attributive Ideal-Real Comparative Analysis), and EAMR (Evaluation by an Area-based Method of Ranking) were applied in this work. Besides, MEREC (Method based on the Removal Effects of Criteria) and Entropy methods were used to determine the weights of the criteria. In addition, the Taguchi method with L18 orthogonal array (6^1+3^3) design was used for the design of an experiment, which has four input factors including the depth of dressing cut, the spindle speed, the feed rate, and the wheel diameter. Two criteria, including the surface roughness (SR) and the material removal speed (MRS) were selected as the response outputs. The reason for choosing these two criteria is because SR and MRS are two very important output factors of a mechanical machining process as well as of the CBN grinding process on a CNC milling machine. In particular, these two criteria are always in conflict with each other. Small SR requirements will require small values of the feed speed and the depth of cut. This will lead to the reduction of MRS. From the results of this study, the use of different methods for MCDM was evaluated. In addition, rankings of alternatives have been given according to MCDM methods. Furthermore, the best alternative to guarantee both the minimum SR and the maximum MRS has been found

The genus Alchemilla L. has about 1000 species in the world flora, of which 35 grow in Ukraine. The most common in Ukraine are A. flabellata Bus., A. phegophila Juz. and A. subrenata Bus. Despite the widespread distribution of species of the genus Alchemilla L. and the publication of a monograph on the herb of the collective species - Herba Alchemillae (Alchemiilla vulgaris L. sensu latiore) in the State Pharmacopoeia of Ukraine, the chemical composition, and pharmacological properties of species of the genus Alchemilla L. are insufficiently studied, therefore, it is advisable to study the chemical composition of the most common species of flora of Ukraine for their introduction into medical and pharmaceutical practice.
The aim of the work was to study the component composition and quantitative content of essential oils of flowers and leaves of some species of the genus Alchemilla L.
Materials and methods. Flowers and leaves of Alchemilla. flabellata Bus., Alchemilla phegophila Juz. and Alchemilla subrenata Bus. harvested in the Ivano-Frankivsk region in 2020 - 2021.
The component composition and quantitative content of essential oils were determined by chromato-mass spectrometric method. The compounds were identified by comparing the obtained mass spectra of the chromatographic peak with the mass spectra of the reference compounds and based on comparison with the spectra of the database. Quantitative determination of the content of substances in the raw material was performed in comparison with a standard sample of menthol.
Results. The essential oil of flowers and leaves of Alchemilla. flabellata Bus., Alchemilla phegophila Juz. and Alchemilla subrenata Bus were obtained. It was found that the highest content of essential oils was characterized by Alchemilla. flabellata Bus. flowers (16884.6 mg / kg), and the least essential oil was contained in the leaves of Alchemilla Phegophila Juz. (4895.5 mg / kg). As a result of studying the component composition of essential oils of flowers and leaves of Alchemilla flabellata Bus., Alchemilla Phegophila Juz. and Alchemilla subrenata Bus. 48, 51 and 47 compounds were identified, of which 44, 48 and 43 were identified, respectively. 31 components of essential oil were common in the studied samples of raw materials.
Conclusions. Due to the component composition of the essential oil of flowers and leaves of Alchemilla. flabellata Bus., Alchemilla phegophila Juz. and Alchemilla subrenata Bus., as well as considering the known pharmacological activity of its components, it is advisable to conduct further pharmacological studies of raw materials of the genus Alchemilla L. to study their antibacterial, anti-inflammatory and antitumor properties

Продолжительность жизни определяется совокупностью различных факторов, одним из которых является самосохранительное поведение. В данной статье рассматриваются особенности самосохранительного поведения и факторы, его определяющие, на примере субъекта РФ с относительно высокой продолжительностью жизни – Республики Татарстан. Работа построена на смешанных методах. Количественные методы опираются на базу данных исследования репродуктивного и самосохранительного поведения населения Республики Татарстан (РСПН РТ), проведенного в 2020 г. Качественные методы – на результаты проведенных в это же время фокус-групп и интервью с экспертами. В рамках исследования выявлено, что факторы риска, такие как курение и потребление алкоголя, в большей степени присущи населению с низким уровнем образования и дохода, часто сельским жителям, русским в большей степени, чем татарам, и мужчинам – чем женщинам, лицам старшего возраста – чем молодежи. Республиканские программы по профилактике заболеваемости вызывают позитивный отклик у населения и приводят к снижению неравенства в доступе к услугам, позволяющим укреплять здоровье.
Тенденции рождаемости в развитых странах в период пандемии COVID-19

Published: July 2022

В статье рассматривается динамика рождаемости в ряде развитых стран в период пандемии COVID-19. На основе данных Human Fertility Database о числе ежемесячных рождений (Short-Term Fertility Fluctuations) проводится анализ тенденций изменения числа рождений с 2000 г. по настоящее время, особое внимание уделено периоду с 2020 г. по первую половину 2021 г. В большинстве рассмотренных стран наблюдается ускоренное снижение рождаемости, которое началось в октябре-ноябре 2020 г. и продолжается в 2021 г. В Испании, Италии, Японии, Южной Корее, Латвии и России число рождений в декабре 2020 г. по сравнению с предыдущим годом в среднем снизилось на 8,03%, в январе 2021 г. – на 13,3%. Наиболее резкое снижение числа рождений среди рассмотренных стран наблюдалось в Испании: оно сократилось на 21,3% в декабре 2020 г. и на 20,8% в январе 2021 г. В ряде стран (Германия, Дания, Нидерланды, Венгрия) наблюдается увеличение числа рождений в период пандемии по сравнению со средним показателем за последние 5 и 10 лет. В некоторых странах (Испания, Италия) снижение числа рождений в период пандемии COVID-19 существенно выше снижения аналогичных показателей после предыдущих экономических или эпидемиологических кризисов. Экономическая и социальная нестабильность, начавшаяся в период пандемии, способствовала снижению числа рождений в развитых странах, которое особенно заметно в декабре 2020 – январе 2021 г. Однако в последствии число помесячных рождений постепенно возвращается к допандемическому уровню. Из этого можно сделать вывод, что влияние короновирусного кризиса на рождаемость в развитых странах, вероятно, будет краткосрочным.
Revisión arqueológica del conjunto molinero del arroyo de San Blas en Carranque (Toledo): un ejercicio de adaptación metodológica

Published: July 2022

El objetivo del estudio que se presenta es la revisión cronológica y funcional del conjunto molinero del arroyo de San Blas, situado junto al yacimiento arqueológico de Carranque (Toledo), con cuya etapa más prolífera tradicionalmente se ha relacionado (ss. III-IV).
Su análisis se planteó desde el inicio como una acción no invasiva, en un ejercicio de adaptación metodológica, que combinó fundamentalmente herramientas propias de la Arqueología de la Arquitectura (estratigrafía, tipología y cronotipología), con el análisis del paisaje (geología, orografía, altimetría) y teniendo presente el principio básico de la gravedad, inherente a cualquier sistema hidráulico histórico.
Los resultados obtenidos de este nuevo acercamiento, plural pero sistemático, permiten distinguir en el conjunto, al menos dos grandes diferentes sistemas para la molienda del grano, con argumentos suficientes para defender su construcción diacrónica en un ambiente tecnológico y constructivo bastante alejado del tradicionalmente defendido para estas estructuras, no en época tardorromana, sino entre las centurias bajomedievales y modernas.

Published: July 2022

Needle stick injuries are preventable causes of fearsome diseases like Hepatitis B and HIV. In spite of this knowledge, the health care providers are quite negligent, and the institutional support too is compromised due to the increased demand for services. The current study is a dipstick audit of the knowledge and practices on NSI (prevention and management) among exposed health care workers, with specific reference to HIV infection in a private health facility in Bhubaneswar city, using an unorthodox tool of Focus Group Discussions among the participants.: The exercise was a part of the academic activity of health promotion on World AIDS Day 2021. Health care workers such as doctors, paramedical staff & utility staff voluntarily participated in the FGD session. Total 3 FGDs were conducted at 3 different places inside the hospital premises. Three moderators were selected previously and after discussing the theme of World AIDS Day, they guided the FGDs with similar probing questionnaires. The sessions were recorded with the help of a recorder and also noted down along with Sociograms. The data gave a real picture of how even premier institutions are complacent regarding the problem. Only 27% knew about the SOPs, and in none of the stations,SOPs were displayed or a register was maintained regarding NSI in their work area. None of the participants were aware of Post Exposure Prophylaxis for the same. This indeed highlighted an ignored aspect of quality health care. The data was an eye-opener in a tertiary care center and from time to time there should be refresher training or sessions to increase the level of awareness.

Abstrak
Generator merupakan suatu alat yang penting pada sebuah pembangkit yang mengubah energi mekanik menjadi energi listrik. Pemilihan material dalam membuat kerangka penyusun generator sangat perlu diperhatikan agar generator yang dibuat memiliki keefektivitasan yang baik saat dioperasikan. Dampak dari pemilihan material kerangka penyusun generator akan mempengaruhi output generator yang dihasilkan. Secara khusus material aluminium memiliki keefektivitasan yang lebih baik dibandingkan material akrilik. Dari kedua material tersebut didapatkan bahwa material aluminium memiliki distribusi kerapatan fluks magentik yang lebih besar dibandingkan material akrilik sehingga output generator berupa tegangan dan frekuensi juga lebih besar. Hasil uji torsi generator dengan kerangka penyusun aluminium lebih kecil dibandingkan kerangka penyusun material akrilik sehingga kinerja generator dengan material aluminnium lebih baik dibandingkan dengan material akrilik.

Abstract
A generator is an important device in a plant that converts mechanical energy into electrical energy. The selection of materials in making the frame of the generator is very important so that the generator made has good effectiveness when operated. The impact of the selection of the material of the generator's constituent framework will affect the output of the generator produced. Specifically, aluminum material has a better effectiveness than acrylic materials. From both materials it is obtained that aluminum material has a greater distribution of magentic flux density than acrylic material so that the generator output in the form of voltage and frequency is also greater. The result of the generator torque test with an aluminum constituent frame is smaller than the acrylic material building frame so that the performance of the generator with aluminnium material is better compared to acrylic material.

Published: July 2022

<p class="06IsiAbstrak">Suspicion of Salafi as terrorist and extremist organization increased after 9/11. Many studies have found that the Salafi ideology contains an exclusive and harsh doctrine of Wahhabism. This article examines the Salafi madrasas which was initially exclusive, rigid, conservative, and anti-state symbols, then transformed into a formal Islamic school that is modern and professional in management, as well as integrating the national education curriculum with Islamic curriculum (<em>diniyyah</em>/boarding school) as a strategy to gain state recognition. Although it is not carried out in all Islamic educational institutions it manages, the transformation of the Salafi madrasas is intended to remove the suspicions of the people who consider them terrorist and extremist group. Therefore, this article also explains the Salafi typology which is divided into two based on the movement model, namely the Ideological Salafi (Purification) and the Jihadist Salafi. Through the multicultural education approach that was written by Bikhu Parekh, this research suggests the implications of the ideas of salafism that are disseminated to the multicultural Indonesian society. This research finds that the Salafi campaign in Indonesia has not completely failed. Salafi madrasas have succeeded in transforming through curriculum integration which aims to reject public suspicion that they are terrorist organizations, in fact this strategy actually attracts upper-middle class people to send their children to Salafi madrasas. </p>
An Approach to Monitoring of Magnetic Parameters of Cores of a Chain of Spheres. Diagnostics of Different Chain’s Length and Core’s Radius

The basic structural elements of the magnetized granular medium (effectively used, in particular, in apparatus of thin magnetic separation) are granule chains (according to channel-by-channel model), in connection with which there is a need to detail the features of their magnetization. The purpose of the work is to develop and implement an approach to measuring magnetic (micro)flows along the cores of different radius r in the chain of granules using a specially developed (by printed circuit board technology) sensor, with high radius R (15 and 20 mm) spheres available for such measurements.From the data of measuring magnetic (micro)flows data of average induction in each of the quasi-continuous cores of the spheres chain are obtained, as well as data of magnetic permeability and susceptibility of these cores, their magnetization for different values of the intensity of the magnetizing field. It is shown that dependences of mentioned magnetic parameters from number n spheres in a chain are generalized on r /R for different R.These relationships, increasing as n increases due to a decrease in the demagnetizing factor N of any of the cores and the chain as a whole, demonstrate the achievement of individually limiting values of magnetic parameters and corresponding auto-model regions where N→0. At the same time, the transition to each of these regions, manifesting almost independently of r /R and intensity, falls on the value of n = 10–12 = [n]. Thus, in fact, such a criterion value [n] distinguishes chains by sufficiently “long” – when n ≥ [n] and “short” – when 2 ≤ n ˂ [n]. Data of demagnetizing factor for different cores of “short” chains of spheres are obtained and phenomenologically described.
Pore-Scale Modeling of Immiscible Displacement In Porous Media: The Effects of Dual Wettability

Published: July 2022

Summary
Many naturally occurring porous media contain different types of grains with different wettabilities, therefore, understanding the effect of wettability heterogeneity on multiphase flow in porous media is important. We investigate the immiscible displacement during imbibition in a dual-wettability porous medium by direct pore-scale modeling. We propose a heterogeneous index (HI) to quantify the wettability heterogeneity. Our simulations on the capillary rise in dual-wettability tubes are compared with theoretical predictions, which verifies the numerical method. Our simulation results on the displacement in the dual-wettability porous media show that the wettability heterogeneity has a great impact on the fluid distribution, the capillary pressure curve, and the relative permeability curve. With the increase of wettability heterogeneity (HI), more capillary fingers are found during the displacement, the recovery rate of nonwetting fluid decreases, and the capillary pressure and the relative permeability of the wetting fluid decrease.
