The objective of the study was to determine the impact of cardiometabolic risk factors on the quality of life of Kinshasa soldiers, carried out in the period from October 5, 2020, to February 2021 where all rank categories of the army: corporals and soldiers, non-commissioned officers and non-commissioned officers, senior officers, aged 19 to 69, took part in this study. The Cardiovascular Exploration Center of the Military Health Corps served as a pilot point. A convenience sample of 899 soldiers who participated in our survey. The data collection was carried out by a self-questionnaire evaluating the 4 areas of human life: (physical health, mental health, social relations, and environment). The scores of the different dimensions of the questionnaires were calculated. The average of these elements was also calculated for each dimension. Scores for all dimensions were obtained. The “General state of health” dimension, whose score varies from 1 to 5, was also carried out. A validated scale has been determined by military category scores calculated such that 0 corresponds to the worst (poor) quality of life and 100 to the best for the multi-item dimensions. Anthropometric, physiological, energy expenditure, and body composition data were also collected. A total of 899 soldiers responded to the questionnaire, made up of 797 men and 102 women, i.e. 88.7% vs. 11.3%. It is shown that the majority of servicemen had a poor quality of life (87.5%) compared to 12.5%. Among the servicemen with low quality of life, it appears that 33.5% were corporals, 28.8% were servicemen (1st and 2nd class), therefore the category of non-commissioned officers (3rd and 2nd class) sergeants -1 Sergeant Major and Warrant Officers have respectively 19.9% and 17.5%, i.e. p<0.001. The majority of soldiers had a secondary school education (69.4%) and 87.5% had at least one morbid history. The quality of life seems to be altered among the soldiers in Kinshasa, and therefore poorly perceived by the same soldiers interviewed.
USING GEOGRAPHICAL INFORMATION SYSTEMS AND REMOTE SENSING TO DETECT RESIN-RICH AREAS FOR PROPOLIS PRODUCTION FROM APIARIES
Authors: Amro Abdulraouf , Abou-shaara Hossam
Published: April 2022

Propolis (bee glue) is considered among bee products with medicinal properties. The majority of plants in Egypt are field crops which cultivated by farmers. Such crops may supply bee colonies with nectar/pollen, but are not good sources for resin due to their short life cycles. This study aimed to explore potential sites for producing high amounts of propolis from bee colonies based on a remote sensing analysis. The study was performed on a Governorate with intensive agricultural activity in Egypt (Assiut Governorate). The methodology depended on isolating trees from the satellite image using unsupervised classification followed by supervised classification based on numerous geographical coordinates of trees. Trees were transferred into points, and then point density was calculated to classify the study location into classes according to density. Sites with the very high numbers of trees were especially recommended for producing propolis on a commercial scale by beekeepers. Giving more attention to propolis production can enhance the income of beekeepers and maximize the economic benefit from bee colonies.
Porosity Dependence of Deformation Bands In The Entrada Sandstone, La Plata County, Colorado
Authors: Smith Gary A.
Published: April 2022

Close examination of zones of deformation bands in the Entrada Sandstone (Middle Jurassic) near Durango, Colorado suggests that the width of these vertical zones and the displacement across them is directly related to the porosity of the sandstone. Low porosity sandstone is less susceptible to fracturing than high porosity sandstone because greater energy is required to propagate cracks through quartz grains and calcite cement than through pore space. This observation is considered a field confirmation of the experimental work by Dunn et al. (1973)
The Nature of The Minnelusa-Opeche Contact In The Halverson Field Area, Powder River Basin, Wyoming
Authors: Moore W. Richard
Published: April 2022

In the Halverson Field area of the eastern Powder River Basin, oil is trapped in porous Minnelusa reservoirs by the Opeche Shale. This study indicates that the Opeche can be divided into two vertical units which were deposited in different environments and that the nature of the contact between the Minnelusa and Opeche is different for the two environments. The lower Opeche was deposited in a channel-fill environment and is in unconformable contact with the Minnelusa, whereas the upper Opeche was deposited in a marine or marginal marine environment and is in conformable contact with the Minnelusa. A paleo-high controlled the area of major facies change. The different environments of the Opeche should lead to different mapping techniques of the two shale units in the exploration for new Minnelusa oil fields.
Introducing Internationalisation at Home
Authors: Gosling Mark , Yang Wenhsien
Published: April 2022

Taiwan higher education institutions are employing two strategies: Internationalisation at Home (IaH) to promote domestic students’ international exposure and awareness, and Content and Language Integrated Learning (CLIL) to promote language skills and professional knowledge. Higher education institutions recognise the synergy of these two strategies and the opportunity through them to attract international students to study in an English-speaking classroom. What is not known is the reaction of the domestic CLIL students in English as a Foreign Language settings to the introduction of native English speakers into their classroom, and this is the focus of this exploratory study. Results suggest that the domestic students are largely positive about the engagement of the exchange students but also raise the issues of internationalised curriculum and intercultural mixing in the monolingual context.
Enacting Moving Images
Authors: Fingerhut Joerg , Heimann Katrin
Published: April 2022

This article highlights ways to relate psychology, neuroscience, and film theory that are underrepresented in the current debate and that could contribute to a new cognitive media theory. First, we outline how neuroscientific approaches to moving images could be embedded in the embodied, enactive cognition framework and recent predictive processing theories of the brain. Within this framework, we understand filmic engagement as a specific way of worldmaking, which is co-constituted by formal elements such as framing, camerawork, and editing. Second, we address experimental progress. Here we weigh the promises and perils of neuroscientific studies by discussing the motor neuron account to camera movements as an example. Based on the limitations we identify, we advocate for a multi-method study of film experience that brings cognitive science into dialogue with philosophical accounts and qualitative in-depth explorations of subjective experience.

В роботі вивчалося ставлення до окремих цінностей здорового способу життя юнаків і дівчат, які навчаються у вищому навчальному закладі і займаються фізичною культурою і спортом. Показано, що в основному студентська молодь негативно ставиться до шкідливих звичок і не припускає їх присутності у своїх обраниць/обранців для створення сім’ї. У ставленні до вживання спиртних напоїв та наявності освіти не зафіксовано відмінностей за гендерною ознакою, проте виявлено, що до обраниці юнаки пред’являють більші вимоги, ніж дівчата до обранця, у ставленні до паління як «ні» та занять фізичними вправами як «да».

Published: April 2022

Research on hollow cross section beams and columns made of laminated bamboo has been carried out. So that the two elements can be assembled into a building structure, it is necessary to do connection. Glued in rod is a new connecting tool whose mechanical properties still need to be studied. For this reasons this research was conducted. To achieve this objective, an experiment was conducted with the independent variables (1) the distance between the two edges, (2) the diameter of the threaded rod, and (3) the embedded length. The results showed that (1) the greater the distance between the two edges, the greater the pull out strength of the glued in rod, (2) the larger the diameter of the threaded rod, the greater the pull out of the glued in rod, (3) the greater the embedded length of the threaded rod, the stronger the pull out of glued in rod, (4) the value of the slip modulus is affected by variations in diameter and embedded length but is not affected by the distance between the two edges. The greatest pull out strength, which is 34.85kN, is achieved at a glued in rod diameter of 12mm with an edge distance of 4.5d and a embedded length of 6d, while the lowest value is 14.38kN lies in steel rods with a diameter of 8mm with a embedded length of 5d and a distance of two edges is 2.5d. The highest slip modulus or the highest stiffness value of 9.75kN/mm is achieved at a diameter of 12 mm with an embedded length of 6d and a distance of two edges of 3.50d. The smallest slip modulus value of 3.75kN/mm was achieved at a diameter variation of 8 mm with an embedded length of 5d and a distance of two edges 2.5d

BİR AKSANLI SİNEMA ÖRNEĞİ OLARAK ANNEMİN ŞARKISI
Authors: LİKTOR Coşkun
Published: April 2022

Son yıllarda film çalışmalarındaki en dikkat çekici gelişmelerden biri, aksanlı sinema, kültürlerarası sinema ve ulusaşırı sinema gibi terimlerle kavramsallaştırılan bir alanın giderek daha fazla ön plana çıkmasıdır. Sürgün, diasporik ve postkolonyal sinemacıların iki farklı kültürün arasında kalmışlıktan beslenen filmlerini anlamlandırmak üzere Hamid Naficy’nin geliştirdiği aksanlı sinema kuramına göre yerinden edilmişlik, sürgünlük, yolculuk, yurt, yurtsuzluk, ulusal kimlik ve aidiyet, bireysel ve kolektif bellek gibi meselelere değinirken benzer biçimsel stratejilere başvuran aksanlı filmler, genellikle egemen sinemanın karşısında konumlanan muhalif bir duruş sergiler. Bu çalışma, Erol Mintaş’ın yerinden edilmişlik deneyimi etrafında şekillenen ilk uzun metrajı Klama Dayika Min’i (Annemin Şarkısı, 2014) Hamid Naficy’nin aksanlı sinema kuramından yola çıkarak incelemeyi amaçlamaktadır. Annemin Şarkısı, 1990’larda Doğubeyazıt’taki köylerinden İstanbul’a göçtükten yirmi yıl sonra kentsel dönüşüm nedeniyle bir kez daha yerinden edilen, bir nevi sürgün içinde sürgüne maruz kalan bir anne ile oğlunun hikayesini anlatır. Bu çalışma, Annemin Şarkısı’nda sürgünlüğün, sürgündeki hayatın ve geride bırakılan yurdun nasıl temsil edildiğini, bu temsillerde hangi biçimsel stratejilerden yararlanıldığını çözümleyerek filmin aksanlı sinemayla paylaştığı tematik ve biçimsel benzerlikleri ortaya koymaktadır. Ayrıca aksanlı sinemada ana izlekler olarak karşımıza çıkan nostalji ve bellek meselelerinin filmde oynadığı kilit rol ayrıntılı bir analize tabi tutularak filmin egemen kültür karşısında politik-ideolojik konumlanışı sorgulanmaktadır. Bu sorgulama dahilinde hem nostalji, bellek, kolektif bellek ve karşı-bellek ile ilgili kuramlardan hem de Laura Marks’ın kültürlerarası sinema hakkındaki görüşlerinden faydalanılmaktadır. Neticede bu çalışmada Annemin Şarkısı’nın bellek yitimine direnmeye ve Kürt kolektif belleğini muhafaza etmeye yönelik mesajlar barındıran, böylelikle ana akım karşısında muhalif bir duruş sergileyen bir aksanlı sinema örneği olarak değerlendirilebileceği gösterilmektedir.
Critical shear stress of red blood cells as a novel integrated biomarker for screening chronic kidney diseases in cases of type 2 diabetes
Authors: Park Il Rae , Choi Jimi , Ha Eun Young , Chung Seung Min , Moon Jun Sung , Shin Sehyun , Kim Sin Gon , Won Kyu Chang
Published: April 2022

BACKGROUND: The glomerular filtration rate (GFR) and albumin-to-creatinine ratio (ACR) have been widely used to identify and manage diabetic kidney disease (DKD). However, classifications based on these two indices do not always concur in terms of DKD diagnosis; for example, cases of high ACR with normal GFR or normal ACR with low GFR may occur. A recent study suggested that critical shear stress (CSS), a hemorheological parameter to represent aggregating force of red blood cells (RBCs), is a potential screening index for DKD. In the present study, we investigated the diagnostic potential of CSS for DKD according to the KDIGO 2012 Guideline. METHODS: A total of 378 patients with type 2 diabetes who visited Yeungnam University Hospital between 2014 and 2017 were included. CSS was measured using a transient microfluidic hemorheometer, Rheoscan-D300® (Rheomeditech, Seoul, Republic of Korea) with whole blood. Patients who were DKD negative (green zone) were compared with patients who were DKD positive (red zone) as Model 1 and patients at risk for (orange zone) and red zones as Model 2, respectively. RESULTS: After exclusion criteria such as eGFR < 30 mL/min/1.73 m2, alcoholism, and macrovascular complications were applied, the sensitivity and specificity were 100% and 77.8% for Model 1 and 75.0% and 72.0% for Model 2, respectively. The diagnostic accuracy measures of the CSS for Model 1 were found to be highly accurate or have the potential to alter clinical decisions. Similarly, the diagnostic accuracy measures of CSS for Model 2 were found to provide useful information, despite them expanding to the orange and red zones. CONCLUSION: DKD was successfully identified using a novel integrated hemorheological index of CSS that satisfied both ACR and GFR criteria. Therefore, CSS may be useful for the additive diagnosis of DKD with GFR and uACR.
Environmental Terrorism: Not Yet an International Crime
Authors: Rose Gregory
Published: April 2022

The ease with which severe harms can be deliberately inflicted upon the natural environment to coerce political behaviour pose real and current threats to both nature and to social stability. There is a serious lack of international law to criminalise environmental terrorism. This lacuna could be remedied in part by the formulation and adoption of a new treaty to define and criminalise acts of terror against the natural environment. The outline of such a treaty is described in this article.

Published: April 2022

Background: Alzheimer’s disease (AD) begins with an asymptomatic “preclinical” phase, in which abnormal biomarkers indicate risk for developing cognitive impairment. Research is increasingly focused on validating biomarkers to improve reliable diagnosis and timely clinical treatment of AD. Most preclinical biomarker research lacks adequate representation of Black/African American and other racially and ethnically minoritized individuals, limiting the applicability of data to these groups. This may exacerbate existing disparities by hindering diagnosis and treatment among racially and ethnically minoritized individuals. Objective: Understand the factors influencing willingness of Blacks/African Americans to participate in AD biomarker research and identify opportunities to improve enrollment. Methods: We enrolled Blacks/African Americans (N = 145) between 46–85 years of age who had previously participated in AD research. Participants gave open-ended responses to a vignette describing a hypothetical biomarker research study. Using qualitative content analysis, we identified themes that motivated and discouraged enrollment in AD biomarker research. Results: Participant responses were categorized into several themes. Themes motivating participation included a desire to know their biomarker results and to support research. Major themes discouraging participation included concerns about potential negative psychological outcomes to learning one’s increased risk for AD, doubt about the usefulness of testing, and worry about the potential physical harms of testing. Conclusion: Understanding themes motivating and discouraging AD preclinical biomarker research participation may inform research material development, approach to community engagement, and/or trial design to increase enrollment of Blacks/African Americans.

Published: April 2022

Background: A positive predictive genetic test for Huntington’s disease (HD) can be a life-changing event for both carriers and their partners, leading to lower wellbeing and increasing the risk for separation and divorce. The ‘Hold me Tight’ program (HmT), based on emotionally focused couples’ therapy, aims at strengthening the couple bond by targeting attachment needs. Objective: This study investigates whether the HmT program helps couples strengthen their relationship, as an investment in a future where the disease will affect life in many ways. Methods: In a multiple baseline design using three baselines of varying length, 15 couples of presymptomatic HD-carriers and their partners were included. In three consecutive groups, couples underwent the intervention (an adapted version of the 8-session HmT program) in four weekly sessions and completed self-report questionnaires throughout the study period of 19 weeks (17 measurements). Attachment style was assessed at baseline, resilience at baseline and at the end of the follow-up, while relationship satisfaction and wellbeing were measured weekly. A multi-level model was applied to the data. Results: Over the course of the study, wellbeing and relationship satisfaction significantly improved; resilience, however, did not. Furthermore, all three outcome measures were moderated by attachment style, with more securely attached individuals showing better outcomes. Conclusion: HmT improved wellbeing and relationship satisfaction of couples facing HD. Due to these improvements and high patient acceptability rates, this program could become a standardized procedure in HD care. The program could be adapted for other populations, e.g., couples facing other genetic neurological disorders.

Published: April 2022

Background:

Exercise intolerance is an important impairment in patients with SMA, but little is known about the mechanisms underlying this symptom.

Objective:

To investigate if reduced motor unit and capillary recruitment capacity in patients with SMA contribute to exercise intolerance.

Methods:

Adolescent and adult patients with SMA types 3 and 4 ( n = 15) and age- and gender matched controls ( n = 15) performed a maximal upper body exercise test. We applied respiratory gas analyses, non-invasive surface electromyography (sEMG) and continuous wave near-infrared spectroscopy (CW-NIRS) to study oxygen consumption, arm muscle motor unit- and capillary recruitment, respectively.

Results:

Maximal exercise duration was twofold lower ( p < 0.001) and work of breathing and ventilation was 1.6- and 1.8-fold higher ( p < 0.05) in patients compared to controls, respectively. Regarding motor unit recruitment, we found higher normalized RMS amplitude onset values of sEMG signals from all muscles and the increase in normalized RMS amplitudes was similar in the m. triceps brachii, m. brachioradialis and m. flexor digitorum in SMA compared to controls. Median frequency, onset values were similar in patients and controls. We found a similar decrease in median frequencies of sEMG recordings from the m. biceps brachii, a diminished decrease from the m. brachioradialis and m. flexor digitorum, but a larger decrease from the m. triceps brachii. With respect to capillary recruitment, CW-NIRS recordings in m. biceps brachii revealed dynamics that were both qualitatively and quantitatively similar in patients and controls.

Conclusion:

We found no evidence for the contribution of motor unit and capillary recruitment capacity of the upper arm muscles in adolescent and adult patients with SMA types 3 and 4 as primary limiting factors to premature fatigue during execution of a maximal arm-cycling task.

Published: April 2022

The mechanism of cycloaddition reaction between phosphenium cation and phosphindene with formaldehyde has been systematically investigated at the B3LYP/6-311++G(d,p) level of theory in order to better understand the reactivity for the valence isoelectronic of carbene. Phosphenium cation acts as an electrophilic reagent and accepts σ electrons of formaldehyde to form a complex in the first addition step. The greater the positive charge on phosphorus atom in phosphenium cation, the more stable the formed complex is. Introduction of substituents will decrease positive charge on phosphorus atom in phosphenium cation. The order of positive charge on phosphorus atom is HP+–F > HP+–OH > HP+–NH2, which is consistent with their Lewis acidities. The complex transforms to a three-membered ring product via a transition state in the second cyclization step. The product is less stable than the complex due to its tension of small ring.

The aim of the article is to improve the design of the original centrifugal grain separator. The separator is designed to separate the components of grain materials by size and aerodynamic properties. The basic design satisfactorily performs the technological process, but has large dimensions vertically. Reducing the size will simplify the design and reduce the cost of the machine. The article proposes to replace the double pneumatic cleaning of grain material with a single one. At the same time the car gets rid of the closed aspiration system. The closed aspiration system has operational advantages, however difficult adjustment reduces indicators of technological efficiency of pneumatic cleaning of grain. The original pneumatic cleaning system allows you to remove light impurities without creating significant air resistance, due to the lack of countercurrent movements. In addition, the use of an inclined pneumatic channel does not require the creation of high-speed airflow. As a result of the proposed improvement simplifies the structure and regulation of the separator, as well as reduces its size and weight. In addition to the modernization of the design of the pneumatic-sieve separator, the article presents the method of design engineering calculation of its basic geometric parameters. Depending on the specific capacity of the upper (ear) sieve and the characteristics of the grain mixture is determined by its length and angle. The remaining geometric parameters are derived from the above. Based on preliminary calculations, the following conclusions can be drawn. The use of the proposed scheme will reduce the height and weight of the centrifugal pneumatic sieve grain separator. Replacing the double air cleaning with a single one will simplify the adjustment of the machine. Experimental establishment of indicators of technological efficiency of the proposed separator will theoretically determine the dimensions and automate the design process of grain cleaning machines created by a similar scheme.

The article considers the issue of increasing the efficiency of coolers of the material heated during drying by using a heat pump unit to produce artificial cold. The scheme of use of a thermal pump in a complex with the drying installation and the portable cooler of material is offered. A mathematical description of the stationary modes of operation of the drying unit, material cooler and heat pump elements on the basis of a steam compressor refrigeration unit is formulated. At creation of physical and mathematical models of heat and mass transfer in the course of drying and cooling of material (grain) the following conditions are accepted simplifying the mathematical description, but without changing real process: moisture from the material is removed according to Dalton's evaporation law, while the moisture in the material evaporates and is removed simultaneously; moisture content and temperature in the volume of the material are evenly distributed, heat and mass transfer occurs only between the surface of the material and the drying agent; the effects of radiation and contact heat transfer are taken into account by heat transfer coefficients; stationary fields of temperature and moisture content are assumed to be one-dimensional, which vary according to the coordinate calculated in the direction of movement of the material; when cooling the moisture removal material is not taken into account for low residual moisture; the size of the surface of the material in the process of drying and cooling does not change; the heat exchange equipment of the heat pump is an object with concentrated parameters. Using the obtained mathematical dependences, graphical dependences of changes in grain and air temperature are constructed, which allow to evaluate the expediency of using a heat pump. The formulated mathematical model of stationary modes of the heat pump drying unit with artificial cooling of the dried material can be used to evaluate the feasibility and energy efficiency of the used refrigeration machines for grain cooling, especially after high-temperature processing. The obtained analytical dependences in the form of a closed system of equations can be used to optimize the parameters of the heat pump drying unit by the criterion of minimizing energy consumption.

The aim of the work is to determine the laser-plasma effect on the structure and microhardness of surfaces of ordinary and after heat treatment by hardening with low and high tempering steel 40HN with different structure, to study the possibility of laser-plasma treatment to strengthen the surface at different stages of manufacturing or repair transport details in the agro-industrial complex. The article presents the results of laser-plasma exposure to the structure and microhardness of surfaces of ordinary and after heat treatment by hardening with low and high tempering steel 40HN with different structure: normalized or annealed steel immediately after machining, and after volumetric heat treatment with different types tempering for different hardness, determined by the purpose of the workpieces. First, the features of the microstructure and hardness of steel with a ferritic-pearlitic structure during laser-plasma treatment were studied. The highest temperature, which causes melting and evaporation of the material, during laser treatment occurs on the surface of the processed products. During further cooling due to intensive heat dissipation into the cold core of the metal in the melting zone is hardening from the liquid state and the formation of martensite. Adjacent to these areas is the zone of martensite obtained by quenching during cooling from the solid austenitic state. Then the influence of laser-plasma treatment on the features of the microstructure and hardness of steel with the structure of tempering sorbitol and with the structure of martensite was considered. Laser-plasma treatment can be used with high efficiency to strengthen structural steels. It allows to strengthen the surface of structural steel to a high hardness of 9-11 GPa to a depth of about 0.2 mm. The hardening effect is obtained on steels with different structure, characteristic for different stages of the techno¬logical process. Therefore, the use of laser-plasma treatment to strengthen the surface is possible at different stages of the technological process of manufacturing or repairing parts of road transport in agriculture.

Features of cutting of a stalk by a blade with sliding are analytically investigated. The conditions of cutting with sliding of a horizontally located stalk with a knife are substantiated, according to which the blade must press on the stalk perpendicular to it and move at an angle ξ to the normal. The marked angle must be greater than the friction angle φ. The limits of change of values of the angle ξ at which cutting of stalks with sliding is possible are analyzed and defined. It is noted that to ensure cutting of the stem with sliding, as well as to simultaneously and rationally reduce the sliding time of the blade on the stem, it is advisable to perform the operation of cutting stems at an angle ξ less than 90 °. The dependence determined by the conditions of observance by the angle ξp of the zone of the desired action of the velocity point of the blade point to ensure cutting of the stems with sliding is established. The theoretical dependence for determining the sliding coefficient is established, which allows to numerically estimate the degree of sliding. It is noted that cutting with sliding requires less force N, less normal pressure than non-slip cutting. Under such conditions, an increase in the angle ξ leads to a corresponding decrease in the force N. The implementation of the results of the study in the cutting machines of harvesters, forage machines, as well as segmental cutters of reciprocating movement of harvesters, will allow due to the quality of the technological process of cutting plant stems with sliding increase in productivity up to 17%.

The power electric distribution systems (PEDS) possess a great dynamics of development. Thanks to this phenomenon in the power electric distribution systems (PEDS) the probability of apparatus of asymmetrical regimes increase monotonously. As a result of this reliability of the functioning of the power electric equipment installed in the electric knots changes. The asymmetrical regimes in the power electric distribution systems (PEDS) accompanied by the short circuit current are a function of a row determinate is a vague factor of probabilistic nature. Coming from it follows that the investigation of the influence of the asymmetrical regimes accompanied by the current of the short circuit on the reliability of the Power Electric Distribution Systems (PEDS) is one of the most important problems of the development the Power Electric Distribution Systems. The short circuit currents influence the structural and functional reliability of distribution networks and at the reliability of electrical equipment installation. The dynamics of changes in the levels of short circuit currents in electrical networks depends on the rate of change of the re-recovering voltage at the short circuit point on the power supply side and on the load side, as well as on the magnitude and rate of power change at the short circuit point on the power source side and on the load side.

The aim of the article is to substantiate the design, derivation and approbation by calculations of formulas for determining the parameters of the sieve with slits that expand in the direction of movement of the processed material. It is established that grain cleaning machines, which currently work on agricultural and processing enterprises with flat sieves, have been used for many years, are well studied and improved, their technical and economic indicators have reached maximum values. The problem is that to ensure the proper operation of existing grain cleaning machines with traditional flat sieves, a large amount of energy costs are spent on additional operations that are not directly related to the separation process, but without them the normal operation of the machine is impossible. This is directly the transportation of grain and cleaning the sieves from grains that are stuck in the cracks and degrade the quality of their work. The substantiation of the technological scheme of the inertial-gravity separator sieve with slits expanding in the direction of movement of the processed material is performed and the influence of its main parameters on the efficiency of separation of grain mixtures is established. The regularities of the movement of the grain mixture on the surface of the sieve are determined, when favorable conditions are created for the passage through the slits of particles that can pass through it. The method of calculation of the basic geometrical and kinematic parameters of a sieve is offered. To implement the proposed calculation method developed software that allows you to convert blocks developed in analytical form of the calculation method in a form that meets the requirements of the architecture of mathematical models and implements the numerical methods of Runge-Kutt and Nelder-Mead. Tests have shown that the quality of separation of wheat grain on the proposed sieve increases by 12-14% compared to existing ones. When implementing the sieves of the proposed design, the issue of influencing the quality of separation of the magnitude of the bar deflection in the end part and their limits for different crops remains unresolved.

Bahasa Inggris merupakan bagian dari tuntutan di era global. Siswa diharuskan untuk menguasai bahasa Inggris baik dalam berbicara (spoken) maupun dalam menulis (written) karena seperti fakta yang ada dalam masyarakat sekarang ini bahwa bahasa Inggris digunakan di hampir di semua bidang seperti pada buku, bidang ilmiah, website, komputer dan lainya. Terlebih pada dunia kerja seorang pelamar kerja pada umunya diharuskan bisa berbahasa Inggris baik aktif maupun pasif. Jadi sangatlah tepat apabila pengajaran bahasa Inggris yang tepat akan berdampak baik pada siswa itu sendiri. Akan tetapi sering kita jumpai pembelajaran bahasa Inggris masih mengalami sejumlah kendala yang menghambat proses belajar siswa. Tujuan kegiatan pengabdian masyarakat ini untuk menerapkan metode Total Physical Response (TPR). Kegiatan ini berlangsung selama 3 bulan, dan berakhir pada bulan Desember 2018. Adapun sekolah yang menjadi target mitra adalah SMP Kanzul Mubarok dan Azzuhriyah. Hasil kegiatan ini adalah siswa lebih tertarik belajar denggan gerakan fisik dan mengerjakan apa yang diperintahkan dalam pembelajaan. Siswa lebih antusias dan hasil lebih baik, walupun masih ada beberapa kendala.

Mendaur ulang  adalah pengolahan sampah atau sisa produk limbah menjadi produk baru yang dapat dipakai lagi secara layak  dengan  salah satu tujuannya  untuk melestarikan lingkungan. Pengabdian kepada masyarakat (PkM) yang dilakukan dimasa pandemi ini memilih obyek limbah rumah tangga berupa pemanfaatan botol bekas air mineral menjadi benda pakai rumah tangga sebagai alat kebersihan yaitu sapu. Pemahaman dan pengetahuan masyarakat yang kurang tentang cara mengolah sisa material tersebut, menjadikan benda bekas menjadi barang yang kurang berguna sehingga banyak yang dibuang dan tidak dimanfaatkan serta dapat sekaligus mengurangi limbah plastik. Kegiatan PkM ini memberikan penyuluhan kepada masyarakat umum khususnya untuk  ibu-ibu pelaku UKM agar dapat memiliki ketrampilan baru mengolah limbah rumah tangga menjadi barang baru yang lebih bermanfaat untuk masyarakat sekitar dan dapat mempunyai fungsi sebagai bahan yang berguna dalam menjaga kebersihan lingkungan di masa pandemi Covid-19. Metode penyuluhan yang dilakukan adalah kualitatif bersifat deskriptif yang berguna untuk menghimpun, memilah, menganalisis dan mengevaluasi data dan informasi yang diperoleh. Melalui PkM diperoleh hasil bahwa sampah rumah tangga berupa botol bekas air mineral dapat diolah menjadi benda pakai rumah tangga, yang fungsional dan mempunyai nilai jual seperti sapu.

Négociations via internet : Etude du comportement négociateur versus consommateur via le web
Authors: Portella Anderson Gonçalves
Published: April 2022

À travers les études menées par le projet INTERNEG (1996), des recherches ont été lancées pour évaluer et émettre des hypothèses concernant l’influence des nouvelles technologies informatiques, où le petit magasin du coin a commencé à négocier via le web avec un autre entrepreneur/consommateur qui auparavant ne serait pas considéré – le commerçant virtuel. Viennent ensuite le « négociateur sans visage », et le « consommateur distant ou virtuel », qui vont interagir géographiquement ou culturellement pour maximiser leurs utilités. Le projet INTERNEG disposait de l’outil INSPIRE comme outil de travail, qui permettrait, à travers un pré-questionnaire, une analyse des messages échangés entre les négociateurs, et un post-questionnaire (non obligatoire), d’évaluer les négociations faites entre les individus qui ne se connaissaient pas. , ainsi que le résultat de leurs négociations. Le but de cet article est d’analyser le commerce sur Internet – précurseurs du commerce électronique, les relations de confiance des consommateurs, les efforts pour rendre les négociations plus interactives et le comportement des négociateurs et des consommateurs. La méthode d’analyse utilisée est basée sur la vision structuraliste dont l’objectif est de découvrir quelles structures supportent toutes les choses que les êtres humains font, pensent et perçoivent, étant encore un courant de pensée dans les sciences humaines qui s’est inspiré du modèle linguistique et qui déduit la réalité sociale d’un ensemble de relations considérées comme élémentaires (ou formelles). Les résultats ont montré que le scénario de négociation avec peu d’échanges n’est pas souhaitable pour persuader les participants d’accepter les offres post-accord, cependant, il suggère que ces offres doivent être accompagnées d’arguments supplémentaires qui rendront la négociation viable et permettront d’atteindre l’optimum de Pareto. commerce virtuel.

Published: April 2022

Религия — величайшая потребность человеческой природы. Точно так же, как тело нуждается в пище, чтобы поддерживать себя, и в знании ума, чтобы развиваться, душа нуждается в мистическо-философско-религиозном опыте для своего совершенствования. В этом кратком анализе будет обсуждаться индуизм, одна из величайших религий предков, зародившаяся в предгорьях Гималаев, Индия, более 10 000 лет назад, и будет сделан краткий анализ этих очень богатых философско-духовных основ, которые повлияли и продолжают оказывать глубокое влияние на веру человечества.
