ДЕПОРТАЦИЯ ЧЕЧЕНЦЕВ В 1944 ГОДУ
Authors: Саидов И.Х. , Цуцулаева С.С.
Published: June 2022

Одна из самых трагических страниц истории чеченского народа – это депортация 1944 года. Чеченцы и ингуши, ложно обвиненные в пособничестве немцам, поголовно были выселены в Среднюю Азию и Казахстан. Об этом написано уже и еще будет написано, потому что такое нельзя ни простить, ни забыть. Это означало бы предать память своих родных, безвременно погибших в далеких степях.
В статье речь идет о том, какие меры предпринимались в пути для осуществления этой операции. Ведь речь шла о живых людях, которые без средств к существованию в один момент были выселены с мест проживания и погружены в эшелоны для дальнего следования. Естественно, что людей необходимо было как-то кормить, лечить, стеречь. И вовсе не ради них самих, а для избежания непредвиденных ситуаций в пути, как например, эпидемии и моры. Как это осуществлялось не столько на бумаге, сколько в действительности, авторы и попытались рассказать в данной статье. Переселенцы испытывали огромные лишения. Голод, холод, болезни буквально косили людей. Особенно тяжело приходилось детям и старикам. При полном попустительстве властей они были предоставлены сами себе. Правда о тех первых неделях и месяцах до сих пор леденит душу.

Authors: Ernawati Nani , Ismail Banuaji
Published: June 2022

Abstrak - Pembahasan tentang Capital Gain menjadi penting karena adanya pendapat bahwa Capital Gain lebih menarik dari pada deviden bagi sebagian investor.  Secara teoritis variabilitas Capital Gain dipengaruhi oleh beberapa variabel, termasuk diantaranya pertumbuhan profitabilitas baik dalam bentuk return maupun margin.  Namun secara empiris ditemukan beberapa gap hasil penelitian dan sebagian besar mengambil rentang waktu antara tiga hingga lima tahun.  Untuk itu analisis ini ditujukan untuk mengisi celah tersebut dan memverifikasi kembali kaitan  profitabilitas dengan Capital Gain (perusahaan terdaftar di Bursa Efek Indonesia) dengan mengambil time series sepuluh tahun.   Metoda penelitian ini menggunakan pendekatan kuantitatif untuk memverifikasi hipotesa dari model regresi terpilih.  Secara purposive diperoleh sampel  pengamatan sebanyak sebelas perusahaan, sehingga seluruh data obervasinya berjumlah empat ratus empat puluh buah.   Melalui uji f terbukti bahwa secara simultan variabilitas Capital Gain tidak dipengaruhi oleh perubahan profitabilitasnya yang diproksikan melalui Return on Asset, Return on Equity dan Net Profit margin, akan tetapi berdasarkan uji t Net Profit Margin dapat mempengaruhi variabilitas Capital Gain. Dengan demikian, selama kurun tersebut, Net Profit Margin dapat digunakan sebagai penentu variabilitas Capital Gain industri tekstil dan garmen.

Abstract – The discussion about Capital Gain becomes important due to the opinion that Capital Gain is more attractive than dividends for some investors. Theoretically, the variability of Capital Gain is influenced by several variables, such as profitability growth in returns and margins is among one of those. However, empirically, several research gaps were found and most of them took between three and five years. For this reason, this analysis is intended to fill the gap and re-verify the relationship between profitability and Capital Gain (a company listed on the Indonesia Stock Exchange) by taking a ten-year time series. This research method uses a quantitative approach to verify the hypothesis of the selected regression model. Purposively, a sample from observing eleven companies has been obtained, untill the amount of whole observational data are four hundred and forty. Through the f test, it is proven that the variability of Capital Gain is not affected by changes in profitability as proxied by Return on Assets, Return on Equity and Net Profit margin, but based on the t test, Net Profit Margin can affect the variability of Capital Gain. Thus, during this period, the Net Profit Margin can be used as a determinant of the variability of Capital Gain in the textile and garment industry.

Published: June 2022

Nanotechnology has attracted the interest of many scientists because the changes in physical properties occurred at the size of 1-100 nm in the form of vast surface area, high mechanical strength, and high porosity. Silica is an element with high uses in various fields such as biotechnology. Silica nanoparticles are silica made on a nanoscale whose use is increasing. Nanosilica is widely used in the industry as a retention and drainage aid, usually associated with cationic polyelectrolytes such as cationic starch. The use of nanosilica in the paper-making process aims to improve the dewatering process and the retention of fine particles such as fines. Retention is one of the important parameters at the wet-end stage because it affects the ability of the additive to be retained on the fiber to the sewage treatment system. However, retention also has a negative impact on the dewatering rate and the physical properties of the paper produced, so that it is often neglected in the industry because it reduces runability in the paper-making system. This research was conducted to determine the effect of modifying cationic starch with nanosilica on retention, drainage rate, and paper properties. In this research, nanosilica was synthesized by using sol gel method, and the synthesis results indicate the presence of a nanosilica functional group and nanosilica at the size of 46-86 nm. In addition, modifying cationic starch with nanosilica with variations of 0.5% and 1% cationic starch and 0.5%, 1% and 1.5% nanosilica. The results obtained indicate that the optimum dose of nanosilica for each of the corresponding cationic starch dose, namely to increase retention and drainage for 0.5% cationic starch, the optimum use of nanosilica is 1% with a retention value of 90% and drainage value of 445 ml, for 1% cationic starch, the optimum use of nanosilica is 0.5% with a retention value of 89.8% with the optimum drainage value of 0% nanosilica and drainage value of 440 ml. In addition to wet-end testing, the sheet properties testing was also conducted to determine the effect of retention due to modification of cationic starch with nanosilica on the sheet physical properties. The test results indicate that the addition of nanosilica to the wet-end system has a positive impact on sheet properties.

PERFECTION OF FUNDAMENTALS OF MATHEMATICAL METHOD OF DESIGN OF HYDROSYSTEMS OF DRIVE OF TECHNICAL MACHINES
Authors: Kravets Svetlana
Published: June 2022

The vast majority of modern research on the study of hydromechanical systems is based on the use of the theory of automatic control and management. One of the main components of technical machines and cells are their drives. Hydraulic drives are often used as power. In general, its functional and operational characteristics have a decisive influence on the properties of hydrodynamic systems and general technical machines. In this regard, close attention is paid to the study of hydraulic power drives. However, the power hydraulic drive of technical machines and units in one form or another necessarily includes both electric and mechanical drives, which turns it into a system of various drive systems. The vast majority of modern research is devoted to the study of hydraulic drives, which are based on spool-type hydraulics, which limits the possibility of using new structural materials in the drive systems of technical machines.
Many technical machines and installations, especially in agro-industrial complexes, work in harsh conditions, with high temperatures and dust, low quality of working fluid and other unfavorable characteristics that significantly reduce the reliability of drive systems equipped with hydraulic spool types and quality equipment. At current levels of working pressure in the hydraulic system, the forces and speeds of the working bodies of technical machines and units of the agro-industrial complex, the compressibility of the working fluid and the flexibility of the hydraulic elements of the drive system are determined, become noticeable, which requires further improvement of theory and methodology.
The theoretical basis of the method of calculating the equipment drive system has been improved on the basis of the complex characteristics of the hydraulic system introduced by the author - the resulting volumetric stiffness is used to simplify the drive modeling process by increasing the accuracy of calculation and analysis of its results.

Published: June 2022

In modern living conditions, when mechanization and automation of production processes becomes a characteristic feature of the development of mechanical engineering, the introduction of innovative projects in engineering and technology is relevant for domestic enterprises. This is especially true in the field of tool production, the field of design, advanced energy-saving technologies, the manufacture of special purpose tools and especially devices and equipment for machine tools. The use of modern advanced technological equipment, namely machine tools, as additional devices that significantly expand the technological capabilities of metalworking equipment and tools. An important place in the classification of machine tools is occupied by universal-assembly devices (USP). Due to the fact that 60% of USP configurations are drilling devices, the use and rational change of the design of the elements is relevant. Existing USP designs, in the vast majority, consist of standardized parts, and sometimes components. In most cases, from the elements of the USP can be practically assembled devices to perform various machining operations on machines of all types. Analyzing in detail the design features of the elements of the USP, we can propose the creation of new, more advanced designs. We substantiate the need to improve the elements of the USP on the example of a split sleeve. The location of the section parallel to the axis of the sleeve limits the capabilities of the existing elements, for example, the use of such conductor sleeves complicates the radial fixation in the layout of the USP. An improved design of the split sleeve has been developed to improve the operational capabilities by changing the orientation of the cut relative to the tool axis. The split sleeve is an intermediate element and is used to secure the conductor sleeve in the bar. As a result of contact with the covered surface, the calculation of contact stresses was performed. The proposed design solution will allow more technological use of USP elements. The new design of the split sleeve has proven its effectiveness due to the improvement of the radial fixation in the hole of the bar, which contributes to the accuracy of tool production operations.

Published: June 2022

exist in the literature examining appetitive traits and diet quality among children. Therefore, this study aimed to assess the correlation between appetitive traits and diet quality among children aged 2-6 years in North Jakarta. This cross-sectional study was conducted in Pejagalan village, North Jakarta. A total of 263 subjects were included in this study. Data collection was performed from January to April 2020. Children’s appetitive trait was measured using a validated child eating behaviour questionnaire (CEBQ), and the Diet Quality Index-International (DQII) was used to calculate diet quality scores in children. Most subjects had a DQII score below 60, indicating that the diet quality in children was classified as poor. Based on the CEBQ score, desire to drink, emotional undereating and satiety responsiveness were the common traits in our subjects. Using the Spearman test, we found that emotional overeating was negatively correlated with children’s diet quality score (r = -0.13, p-value < 0.05). Linear regression models showed that food responsiveness was a positive predictor of the ‘variety’ component (β = 0.16, p-value < 0.05), and satiety responsiveness was found as a positive predictor of the moderation component of diet quality (β = 0.17 p-value < 0.05). These findings suggest the potential use of tools, such as the children's emotional overeating assessment, food responsiveness and satiety responsiveness assessments, to identify the risk of poor diet quality and plan an integrated intervention for dietary improvement among children.

Published: June 2022

Complementary and alternative therapies (CATs) are tremendously popular as an adjunct treatment for treating various health conditions but limited literature is available on the extent of use and perception among adolescents. This study aimed to 1) assess the general utilization and perception toward CATs and 2) compare the perception between CATs users and non-CATs users among secondary school students in Kuala Terengganu. A cross-sectional study was conducted among 99 students of a secondary school in Terengganu, Malaysia using convenience sampling. Responses were analysed via descriptive analysis and non-parametric tests using SPSS (v21). Among the participants (age = 15.3 ± 0.6 years; female = 78.8%), 23.2% had previously used some types of CATs, with herbal or dietary supplements (56.5%) being the most common. Participants’ utilization towards CATs were mostly influenced by their family and friends (82.6%). The students gained information about CATs from the internet (67.7%), followed by physicians (62.6%) and family/friends (61.6%). Most students have favourable opinions regarding CATs usage with no significant association between CATs users and non-users (p > 0.05). Nonetheless, CATs users scored higher in their beliefs that CATs has fewer side effects in comparison to conventional medicine (p = 0.050). From the findings, this study has provided some early evidence on the positive perceptions harboured by adolescents in Terengganu regarding CATs. Further approaches should be taken to educate the students about the fundamentals of CATs use to ensure their safety and efficacy.

Out of the frying pan into the fire: The impact of the pandemic on the listening environment of public service interpreters in Finland as experienced by interpreters themselves
Authors: Viljanmaa Anu
Published: June 2022

This article looks at the impact of the pandemic on the work environment of public service interpreters in Finland from a listening-oriented perspective. The rapid switch to remote interpreting in all public service interpreting settings, i.e., the use of virtual meeting tools such as Teams alongside traditional telephone interpreting, affected the listening conditions of public service interpreters dramatically during the spring and summer of 2020. Later during the year, interpreters were able to return to face-to-face interpreting, but encountered yet a new interaction and listening reality: interpreting with face masks. The theoretical framework of this study consisted of the stages of the relational listening process (Halone & Pecchioni, 2001), and the concept of external listening filters in dialogue interpreting (Author, 2020, pp. 481–488). The focus was on the interpreters’ experience of working in three different interactional settings that involved external listening filters: remote interpreting via the phone, remote interpreting via video link, and interpreting in-situ while wearing a face mask. The research data consisted of 357 individual answers from 41 practising interpreters to an electronic survey on the topic carried out in November 2021. The results of the qualitative content analysis show that interpreters have mixed feelings about the technical solutions used during the pandemic in 2020 and 2021. Some respondents have come to prefer remote interpreting, whereas others rather interpret in-situ, despite having to wear face masks. All three interaction modes have both negative and positive aspects from the interpreter’s perspective. Most respondents considered interpreting with face masks difficult in many ways. Research is needed on the long-term effects of the use of face masks on interpreters’ wellbeing.

Published: June 2022

The paper presents an investigation on a timber joint with an inserted steel plate under fire exposure. According to standard EN 1995-1-2 (2004), the fire resistance of unprotected timber joints is limited to 30 min. However, several studies have shown that these joints can achieve higher fire resistance comparing to values given in the standard. In order to verify this, a numerical model of bolted steel-timber joint at elevated temperature was created. The presented model is focused on heat transport in the joint, which is affected by the presence of the steel plate and bolts. The model was validated on experimental results taken from literature and on measurement from a fire tests conducted in a medium-sized furnace. Considering the results of validation, the model has a good ability to predict residual cross-section, temperature of steel plate and bolts and temperature of timber elements. The results of validated numerical model are also compared to the analytical model.

Published: June 2022

A roll tensioning process for circular saw blades with four typical body structures was built with the finite element method. After roll tensioning, the elastoplastic deformation behaviors of the four blades were simulated and tested and the effects of roll reduction displacement on flatness were analyzed. The abilities of the blades to withstand cutting temperature load after the roll tensioning process were compared. The theoretical results showed that each of the four circular saw blades with unique body structures had different process parameters in an appropriate tensioning state. Circular saw blades with different body structures showed variation in improvements of their ability to withstand cutting temperature load after an appropriate tensioning process.

Published: June 2022

Latest scientific findings and policy guidelines emphasize the importance of returning bio-based waste raw materials through cascading use, also including post-consumer wood (PCW). To accomplish the concept of cascading use it is crucial to properly sort PCW given by the quality of raw materials which is resource consuming process. For this purpose, we have (1) selected appropriate activities, (2) constructed a model with different sub models in time, fuel and energy consumption, and (3) defined the inputs, performed calculations and presented (mid) outputs. In the case study all sub models have been compared with each other, demonstrated on the example of Slovenia. The results show that the reuse of wood is justified and should be implemented to a greater extent. Sensitivity analysis has exposed that modifying the values of the input parameters or (mid) outputs may change the final results in time and fuel consumption among selected sub models.

We compare the X-ray profiles and fluxes of the Crab pulsar before and after the glitches in 2017 and 2019, using the data collected by the Insight-HXMT, NICER, and Fermi/GBM, to test whether there is any evidence for magnetosphere rearrangement after glitch. For the 2017 glitch, the profiles from Insight-HXMT (27–200 keV) and NICER (0.5–10 keV) remain unchanged within rms 0.47% and 0.28%, respectively, while the pulsed fluxes measured by these two detectors remain stable with 1σ uncertainty of 0.07% and 0.011%. Considering that the persistent offset of the spin-down rate post-glitch is 0.13% and the X-ray luminosity of the Crab pulsar is proportional to

, we find that the X-ray flux does not increase proportionally to the spin-down power at a significance of about 2.8σ by fitting the flux measurements with a Heaviside function, and thus the additional torque constantly braking the pulsar spin post-glitch is unlikely due to a global magnetosphere variation. For the 2019 glitch, after which a possible soft X-ray polarization variation was detected, the profiles remain unchanged within rms 2.02%, 0.35%, 0.90%, and 0.47% in 10–200, 0.5–10, 3–4.5, and 27–200 keV, respectively, suggesting that the geometry of the X-ray emitting region after the glitch is similar to the pre-glitch one. Therefore the possible polarization variation during the 2019 glitch is unlikely a consequence of the overall magnetosphere changes. The invariance of the pulse profiles is also verified by Kolmogorov–Smirnov tests and that of pulsed fluxes by Z-tests.
The Cosmic History of Long Gamma-Ray Bursts
Authors: Ghirlanda Giancarlo , Salvaterra Ruben
Published: June 2022

The cosmic formation rate of long gamma-ray bursts (LGRBs) encodes the evolution, across cosmic times, of the properties of their progenitors and of their environment. The LGRB formation rate and the luminosity function, with its redshift evolution, are derived by reproducing the largest sets of observations collected over the last four decades, namely the observer-frame prompt emission properties of the GRB samples detected by the Fermi and Compton Gamma Ray Observatory satellites and the redshift, luminosity, and energy distributions of the flux-limited, redshift-complete samples of GRBs detected by Swift. The model that best reproduces all these constraints consists of a GRB formation rate increasing with redshift ∝(1 + z)3.2, i.e., steeper than the star formation rate, up to z ∼ 3, followed by a decrease ∝(1 + z)−3. On top of this, our model also predicts a moderate evolution of the characteristic luminosity function break ∝(1 + z)0.6. Models with only luminosity or rate evolution are excluded at >5σ significance. The cosmic rate evolution of LGRBs is interpreted as their preference for occurring in environments with metallicity

Finally, we estimate that at least ≈0.2−0.7 yr−1 of the Swift- and Fermi-detected bursts at z < 0.5 are jets observed slightly off-axis.
Strategies to improve the vaccine distribution and community awareness of taking COVID-19 vaccine in rural areas in Indonesia
Authors: Sudari Florence , Priskilla Ilga , Febiola Monica , Sinuraya Rano K.
Published: June 2022

COVID-19 has spread worldwide, and several governments, including Indonesia, are actively vaccinating. However, numerous factors may contribute to decreased vaccination administration, including hesitation, a lack of information, and demographic considerations. Therefore, this review provides insights on maximizing vaccine distribution and raising community awareness about COVID-19 vaccination in rural regions with difficulty in transportation access, a lack of health care workers, and limited vaccine storage facilities. It was discovered that numerous potential methods, such as the Internet of Things (IoT), bio-tracking and bio-detect, P-median, and Vehicle Routing Problem (VRP), can monitor vaccination delivery in rural parts of Indonesia. The correct vaccine distribution system can monitor situations during distribution by combining IoT technology with bio-tracking and bio-detect in airborne transportation. Besides enhancing vaccine distribution technologies, healthcare professionals play a critical role in maintaining vaccine quality and improving community awareness of diseases. In particular, as a healthcare professional, a pharmacist has an essential role in ensuring the quality of the vaccine until it is administered to the patient and improving patients’ awareness of COVID-19 and the vaccinations. Pharmacists can collaborate with other healthcare professionals to educate the community to identify important information related to wrong perceptions about COVID-19 and vaccinations.
Lanternfish otoliths (Myctophidae, Teleostei) from the Miocene of Japan
Authors: Schwarzhans Werner , Ohe Fumio , Tsuchiya Yuki , Ujihara Atsushi
Published: June 2022

Lanternfishes (Myctophidae) are one of the most common groups of fishes in the mesopelagic zone of the world ocean, and their otoliths have been dominant in pelagic sediments since at least Miocene times. Many species have a wide geographic distribution, with several being circumglobal. This wide distribution makes myctophid otoliths potentially useful for supraregional stratigraphic purposes. The Sea of Japan and the Northwest Pacific is an important region for investigations into the diversity and evolution of the Myctophidae. Here, we describe a large collection of myctophid otoliths from the late early to early middle Miocene (late Burdigalian to early Langhian) from six localities on western and central Honshu, which were under warm water influence during that time. A total of 22 species are recognized, of which eight are new. In the order in which they are described, the new species are Bolinichthys higashibesshoensissp. nov., Ceratoscopelus brevissp. nov., Lampadena eximasp. nov., Lampanyctus lenticularissp. nov., Lampanyctus tsuyamaensissp. nov., Stenobrachius ohashiisp. nov., Diaphus epipedussp. nov., and Diaphus watatsumisp. nov. At least nine species are also known from coeval sediments outside of Japan, most notably New Zealand and Europe. This distribution reflects the extraordinary geographic spread of myctophid species already in the early Miocene and indicates the potential for their future use for biostratigraphic purposes. The paleoecological and paleobiogeographical implications of the studied myctophid otolith assemblages are discussed. Furthermore, the stratigraphic ranges of the observed species are discussed and compared with data from other regions of the world in an attempt to outline the potential future application of myctophid otoliths for supraregional biostratigraphic purposes.
Réalité virtuelle et alliance thérapeutique : étude de cas démontrant l’intérêt chez des patients hospitalisés en psychiatrie avec une faible alliance thérapeutique
Authors: Burckel Anaïs
Published: June 2022

Notre article est un retour d’expériences de cinq prises en charge psychothérapiques individuelles de patients hospitalisés en psychiatrie, en suite d’un épisode de décompensation ou d’aggravation de leur symptomatologie, la moyenne d’âge étant de trente-cinq ans. Il argumente l’intérêt clinique de l’utilisation de la réalité virtuelle avec des sujets hospitalisés en psychiatrie présentant une faible alliance thérapeutique initiale. L’échelle d’évaluation de l’alliance thérapeutique WAI-T (Horvath, Greenberg, 1989) a été systématiquement remplie par le psychologue afin de mesurer la consistance des items lien, tâche et objectif au début du suivi. Nous avons ensuite privilégié l’observation clinique à partir de critères objectifs prédéfinis en milieu et fin de prise en charge. L’introduction de la réalité virtuelle pour ces patients a permis un renforcement du contrat thérapeutique, une implication dans le suivi sans abandon, une contention des passages à l’acte chez certains d’entre eux. Ces bénéfices soulignent la pertinence de recourir à cette nouvelle technologie au sein des suivis psychothérapiques, à partir d’indications précises, notamment en thérapie cognitivo-comportementale.
Publicité et techniques d’influence, analyse pragmatique d’une illusion d’efficacité
Authors: Laurens Stéphane
Published: June 2022

L’objectif, dans ce texte, est d’analyser les ressorts de l’illusion selon laquelle la publicité ou d’autres techniques d’influence pourraient facilement et rapidement changer nos opinions. En posant la réalité et le sujet comme seuls éléments essentiels et en éliminant les intermédiaires qui, partant de l’objet, conduisent à l’élaboration de l’idée, il ne reste qu’un face-à-face potentiellement spectaculaire : la correspondance immédiate idée – objet, qui donne à voir des changements d’opinions rapides sans liens à la réalité. L’analyse pragmatique des études de Asch sur l’influence et celle de la publicité à travers le processus de mise sur le marché d’un produit montrent que ces changements d’opinion sont le fruit d’élaborations masquées par un discours fallacieux qui laisse croire à de puissantes influences capables de produire d’irrépressibles changements arbitraires.
La femme et la famille selon Auguste Comte
Authors: Petit Annie
Published: June 2022

Pour la société à « réorganiser », Comte repense les relations entre les sexes et la politique de la famille. Dans sa jeunesse il affiche des positions « libérales ». Appuyant ensuite sa sociologie sur la biologie et sur l’histoire, il fait de la famille l’élément social fondé autour d’un rapport homme-femme très différencié où l’un exerce l’autorité et l’autre est affectivité et soumission. Comte systématise aussi ses positions à partir de l’échec de son propre couple, d’un amour sublimé, et des femmes côtoyées. Ambivalences voire paradoxes s’accumulent dans ce conservatisme familial réformateur qui se prétend militant pour la femme.
Le financement participatif est-il l’objet d’un biais domestique ? Cas d’une microbrasserie locale
Authors: Cuénoud Thibault , Giacomoni Gilbert , Dang Rey , Houanti L’Hocine
Published: June 2022

La littérature rappelle régulièrement l’intérêt des citoyens à financer des porteurs de projet. Lorsque ces contributeurs viennent à financer des projets via des plateformes de financement participatif, ils bénéficient, d’après la littérature, d’une asymétrie d’information réduite, d’un coût d’information proche de zéro et d’un accès à une myriade de projets. La théorie financière définit un biais local selon lequel les investisseurs préfèrent détenir des titres géographiquement proches. La théorie moderne du portefeuille de Markowitz (1952) considère cette situation comme une anomalie décisionnelle. Inversement, les investisseurs pourraient s’engager rationnellement dans des entreprises locales s’ils percevaient des rendements supérieurs à la moyenne, si la proximité géographique leur permettait d’obtenir des informations privilégiées sur l’entreprise (et ce faisant de réduire l’asymétrie d’information) ou les rendait plus à même d’exercer un droit de contrôle. À travers notre recherche sur une microbrasserie locale rochelaise, nous étudions le rôle du biais local et domestique (cercle familial et amical) dans les choix de financement participatif.
