Melihat besarnya peningkatan usaha di Indonesia, maka untuk bisa mempertahankan usaha ditingkat nasional maupun internasional perusahaan harus memiliki keunggulan kompetitif. Dengan demikian, diperlukan perencanaan-perencanaan agar semua berjalan semestinya. Menurut Eunike et al. (2018) perencanaan produksi yaitu suatu kegiatan evaluasi fakta pada masa lalu serta kegiatan antisipasi perubahan dan kecenderungan pada masa yang akan datang guna menentukan strategi dan penentuan banyaknya produksi yang tepat agar dapat memenuhi permintaan secara efektif dan efisien. Pada UMKM Makaroni Iko selama ini dalam menentukan jumlah produksi dengan berbagai varian rasa makaroni hanya ditentukan dengan perkiraan. Jumlah makaroni Iko yang diproduksi pada November 2020 sebanyak 2.350 pcs sedangkan jumlah permintaan makaroni Iko sebanyak 2.625 pcs. Dengan begitu UMKM Makaroni Iko tidak bisa memperoleh keuntungan yang optimal. Tujuan dari penelitian ini yaitu mengetahui model matematis dari optimalisasi banyaknya produksi makaroni Iko pada Desember 2020, mengetahui pengoptimalan produksi makaroni Iko untuk memaksimalkan keuntungan menggunakan linear programming dan mengetahui hasil analisis sensitivitas dalam optimalisasi jumlah produksi makaroni Iko menggunakan linear programming programming berbantu POM-QM. Metode yang digunakan pada penelitian ini yaitu linear programming menggunakan metode simpleks dan dilanjutkan dengan analisis sensitivitas. Pengambilan data diperoleh dari survei dengan cara melakukan wawancara kepada pihak Makaroni Iko. Data yang dibutuhkan dalam penelitian ini yaitu data ketersediaan bahan baku dan keuntungan yang diperoleh. Setelah dilakukan optimasi dengan linear programming diperoleh solusi optimal, dimana perusahaan akan mendapatkan laba sebesar Rp 10.571.300 dengan jumlah produksi makaroni Iko sebanyak 3.149 pcs. Berdasarkan pengolahan yang telah dilakukan dengan bantuan software POM-QM dapat diketahui bahwa ada variabel pengetat (slack/surplus) bernilai bukan nol sehingga hal tersebut menunjukkan bahwa masih terdapat bahan baku yang ada belum optimal.

From Captivity to Liberation: Women’s Metamorphosis Through Self-Awareness in Sarah Daniels’ The Devil’s Gateway
Authors: ÖZATA Cüneyt , ŞARMAN Güzin
Published: April 2021

The years beginning with 1960 witnessed several alterations in the thoughts of the women identified as ‘second-wave’ feminists with regard to both social and political perspectives, which was led by the influence of women’s movements. The women of that period directed their attention more to such matters like discrimination, gender, inequality, and violence whereas they were still interested in domestic issues. Women’s new interests were fundamental sources of the works of such prominent feminist playwrights like Sarah Daniels displaying tendencies towards second-wave feminism. In this study, one of the debatable plays of her, The Devil’s Gateway (1983) is analysed in terms of the gradual transformation of the female characters through self-awareness, regarding their positions in both domestic and public domain as well. In the light of the background of Daniels’ period, with hermeneutic analysis and feminist criticism, the study also aims to observe triggering factors for the women’s awakening in detail from the very beginning to the end of the play. The evaluations of the study are revealed in the conclusion part.

Bedensel Sorunlar Çerçevesinde Karşılaştırmalı Bir İnceleme: Dokuzuncu Hariciye Koğuşu ve İnsanın Esareti (Of Human Bondage)
Authors: BRITTEN Fatoş Işıl
Published: April 2021

Fiziksel rahatsızlıklar, bedensel kusurlar gibi bedene dair sorunlar dünya edebiyatında sıklıkla karşımıza çıkan konulardır. Edebiyatın bu tip sorunlar yaşayan kurgusal karakterler üzerinden duygudaşlık geliştiren katartik bir gücü olduğu yadsınamaz. Özellikle psikolojik tahliller açısından zengin bir edebî metin, hem bedensel sorunların bireylerin kişiliklerini nasıl etkilediğini hem de ki-şilerin içinde bulundukları duygu durumlarını anlamamıza yardım eder. Bu noktada Türk edebiya-tının sayılı romanlarından biri olan Peyami Safa’nın Dokuzuncu Hariciye Koğuşu (1930) ve İngiliz edebiyatının beğenilen romanlarından W. Somerset Maugham’ın İnsanın Esareti (Of Human Bon-dage) (1915) bedensel sorunları ve bunların yol açtığı doğrudan ve dolaylı ruhsal acıları başkahra-manların iç dünyaları aracılığıyla ele alır. Dokuzuncu Hariciye Koğuşu’nun isimsiz genci dizinde oluşan kemik vereminden dolayı giderek artan bir şekilde yürüme güçlüğü çekmekte ve bacağının kesilmesi endişesini taşımaktadır. İnsanın Esareti’nin ana karakteri Philip Carey ise doğumsal bir deformasyon olan yumru ayak sorunu ile baş etmeye çalışır ve o da yürüme güçlüğü çekmektedir. Bu noktada bu romanlar oluşum romanı (Bildungsroman) olmaları yani çocukluktan olgunluk dö-nemine geçişi anlatmaları bakımından dikkat çekicidir, çünkü bu edebî alt tür sayesinde okuyucu genç yaşlarda bahsedilen başkahramanların kişiliklerinin nasıl oluştuğunu gözlemleme fırsatı yaka-lar. Bu tür detaylar bedensel sorunların psikolojik yansımalarını ortaya çıkarmak açısından bu ro-manlara yardımcı olur. Bu çalışmada Peyami Safa’nın Dokuzuncu Hariciye Koğuşu ve W. Somerset Maugham’ın İnsanın Esareti (Of Human Bondage) romanları karşılaştırmalı edebiyat disiplini çer-çevesinde incelenecek olup romanlar arasındaki paralellikler görünür kılınacaktır.

Beyond traditional library spaces: the practicalities of closing hospital libraries and opening a virtual library
Authors: Cooke Carol
Published: April 2021

The formation of the University of Manitoba Health Sciences Libraries (UMHSL) was the result of signing consecutive agreements over a period of 24 years between the University of Manitoba (UM) and Winnipeg area hospitals, now collectively known as the Winnipeg Regional Health Authority (WRHA). In 2017, the UMHSL included the UM's Neil John Maclean Health Sciences Library (NJMHSL) and eight hospital and health centre libraries located in the city of Winnipeg. In 2018, all the hospital and health centre libraries closed and the UML opened the rebranded WRHA Virtual Library. This article describes the complications and lessons learned while closing the hospital libraries and opening a virtual library service to a distributed health care system with diverse clinical and educational needs.
Challenges with organization, discoverability and access in Canadian open health data repositories
Authors: Thornton Gail M. , Shiri Ali
Published: April 2021

Introduction: Open health data provides healthcare professionals, biomedical researchers and the general public with access to health data which has the potential to improve healthcare delivery and policy. The challenge for data providers is to create and implement appropriate metadata, or structured data about the data, to ensure that data are easy to discover, access and re-use. The goal of this study is to identify, evaluate and compare Canadian open health data repositories for their searching, browsing and navigation functionalities, the richness of their metadata description practices, and their metadata-based filtering mechanisms.Methods: Metadata-based search and browsing was evaluated in addition to the number and nature of metadata elements. Canadian open health data repositories across national, provincial and institutional levels were evaluated. Data collected using verbatim text recording was evaluated using an analytical framework based on the 2019 Dataverse North Metadata Best Practices guide and 2019 Data Citation Implementation Project roadmap.Results: All six repositories required filtering to access “open health data”. All six repositories included subject facets for filtering, and title and description on the Results List. Inconsistencies suggest that improvements should address advanced search, health-specific search terms, records for all repositories and links to related publications.Discussion: Consistent use of title and description suggests that an interoperable interface is possible. Records indicate the need for explicit, easy to find mechanisms to access metadata in repositories. The analytical framework represents first draft guidelines for metadata creation and implementation to improve organization, discoverability and access to Canadian open health data.

Embracing the value of research data: introducing the JCHLA/JABSC Data Sharing Policy
Authors: Read Kevin , Campbell Alanna , Kitchin Vanessa , MacDonald Heather , McKeown Sandra
Published: April 2021

As health sciences researchers have been asked to share their data more frequently due to funder policies, journal requirements, or interest from their peers, health sciences librarians (HSLs) have simultaneously begun to provide support to researchers in this space through training, participating in RDM efforts on research grants, and developing comprehensive data services programs. If supporting researchers' data sharing efforts is a worthwhile investment for HSLs, it is crucial that we practice data sharing in our own research endeavours. sharing data is a positive step in the right direction, as it can increase the transparency, reliability, and reusability of HSL-related research outputs. Furthermore, having the ability to identify and connect with researchers in relation to the challenges associated with data sharing can help HSLs empathize with their communities and gain new perspectives on improving support in this area. To that end, the Journal of the Canadian Health Libraries Association / Journal de l’Association des bibliothèques de la santé du Canada (JCHLA / JABSC) has developed a Data Sharing Policy to improve the transparency and reusability of research data underlying the results of its publications. This paper will describe the approach taken to inform and develop this policy.

Аerodynamic drag at small Reynolds numbers and the method of calculation of the air velocity in one- and many-row finned beams with an exhaust shaft
Authors: Marshalova G. S. , Sukhotskii А. В.
Published: April 2021

The periodic switching of fans at certain ambient air temperatures and a constant power is a promising method to enhance the energy operating efficiency of air-cooled heat exchangers. Equipping these heat exchangers with devices increasing the propulsion (for example, an exhaust shaft) facilitates the intensification of heat transfer due to strengthening the free movement of air by lifting forces. Meanwhile, the heat exchanger is used at the mixed convection regime. To make the thermal design of air-cooled heat exchangers with an exhaust shaft, we must have data on the aerodynamic drag of tube beams at small Reynolds numbers (Re < 1000) that permit to calculate the air flow velocity. However, at present, studies on the aerodynamic drag at mixed convection are virtually missing. Moreover, it is necessary to take into account the influence of external air flows on the gravitational pull created by the shaft since air-cooled heat exchangers are designed for outdoor use. Using the results of the experimental investigation, we obtained information about the mass-exchange processes in the finned beam and the exhaust shaft, developed a method for calculating the air velocity in one- and many-row finned beams with the exhaust shaft and determined their aerodynamic drag at small Reynolds numbers. We also established the influence of external air flows on the gravitational pull created by the shaft.
Study of (In2S3)х·(AgIn5S8)1–х solid solutions
Authors: Bodnar I. V. , Feshshenko А. A. , Khoroshko V. V.
Published: April 2021

Herein, single crystals of compounds In2S3, AgIn5S8 and solid solutions (In2S3)x·(AgIn5S8)1–x were grown by directional crystallization. The composition of the obtained single crystals was determined by microprobe X-ray spectral analysis. It is found that the content of the components in the grown single crystals is in satisfactory agreement with the specified composition in the initial charge. The structure of the obtained materials was determined by the X-ray method. It is shown that both the initial compounds and the solid solutions based on them were crystallized in the cubic structure of the spinel. The unit cell parameters of the In2S3, AgIn5S8 compounds and the solid solutions based on them, which vary linearly with the composition x, were calculated by the least squares method. The density was determined by the pycnometric method, and the microhardness of the In2S3 and AgIn5S8 compounds and the (In2S3)x·(AgIn5S8)1–x solid solutions was determined by the Knoop method. It is shown that the density, like the unit cell parameter, changes linearly with the composition x, but the dependence of microhardness on the x parameter has a maximum for x = 0.4. Using differential thermal analysis (DTA), the temperatures of phase transformations were determined and the phase diagram of the In2S3–AgIn5S8 system was constructed, which is characterized by a small crystallization interval and belongs to type III according to the Rosebom classification. The curves of liquidus and solidus are concave to the abscissa axis and have a common point.
Approximate evaluation of the functional integrals generated by the Dirac equation with pseudospin symmetry
Authors: Ayryan Е. A. , Hnatic М. , Malyutin V. В.
Published: April 2021

In this paper, the matrix-valued functional integrals generated by the Dirac equation with relativistic Hamiltonian are considered. The Dirac Hamiltonian contains scalar and vector potentials. The sum of the scalar and vector potentials is equal to zero, i.e., the case of pseudospin symmetry is investigated. In this case, a Schrödinger-type equation for the eigenvalues and eigenfunctions of the relativistic Hamiltonian generating the functional integral is constructed. The eigenvalues and eigenfunctions of the Schrödinger-type operator are found using the Sturm sequence method and the reverse iteration method. A method for the evaluation of matrix-valued functional integrals is proposed. This method is based on the relation between the functional integral and the kernel of the evolution operator with the relativistic Hamiltonian and the expansion of the kernel of the evolution operator in terms of the found eigenfunctions of the relativistic Hamiltonian.

Authors: Korzyuk V. I. , Rudzko J. V.
Published: April 2021

In this article, we study the classical solution of the mixed problem in a quarter of a plane for a one-dimensional wave equation. On the bottom of the boundary, the Cauchy conditions are specified, and the second of them has a discontinuity of the first kind at a point. The smooth boundary condition is set at the side boundary. The solution is built using the method of characteristics in an explicit analytical form. The uniqueness is proved, and the conditions under which a piecewise-smooth solution exists are established. The problem with conjugate conditions is considered
Нeat transfer processes in the gas placed into a newtonian gravitation field
Authors: Saverchenko V. I.
Published: April 2021

In this paper, using the theoretical and numerical investigation of molecular motion, we study heat transfer processes in the gas placed in a Newtonian gravitational field. The influence of gravity on the heat conductivity of the gas is analyzed. The gravity considered is more than 100 000 times higher than that of the Earth. The main differences of the gas heat conductivity under such high gravity from the one detected under normal gravity are demonstrated and explained. It is shown how the thermal equilibrium for the heat conductivity of the gas depends on gravity and the type of gas. The difference between natural gravity and the centrifugal force is discussed. It is shown how the gas density influences the thermal equilibrium for the heat conductivity under a strong centrifugal force. The convective heat transfer in the gas placed into a gravitational or centrifugal field is analyzed. It is shown that the thermal equilibrium of the convective heat transfer under intensive gravity is not the same as under normal gravity. The horizontal convection mechanism is discussed. A technical way of the realization of gravity thermal effects in the gas is represented. All necessary parameters of the experimental setup are given.
Radiation diffusion in a ultra-relativistic expanding shell in relation to gamma-ray bursts
Authors: Siutsou I. A. , Kurguzava А. Е.
Published: April 2021

The present-day observational data obtained by satellite  observatories cover seven decades of gamma-ray energy, and there is no universal general model describing the formation of the spectrum. Therefore, it is important to describe the initial stages of radiation propagation in an ultrarelativistically expanding shell. The aim of this study was to obtain equations describing the propagation of radiation in a relativistically expanding shell in the diffusion limit, solve them for natural initial data, and apply the results obtained to the initial radiation of gamma-ray bursts. The following results were obtained: the initial stage of the gamma-ray burst in a photon-thin case can be described by radiation diffusion in an ultrarelativistically expanding shell; the time interval at which it is still possible to use the diffusion approximation increases with increasing the depth inside the shell quadratically; the value of the depth beyond which the diffusion approximation can be used increases, and the value of the radiation intensity decreases in diffusion time approaches; during the main radiation of the photon-thin shell, the diffusion approximation is suitable for most of the jet. The parameters of emission are close to the ones of short gamma-ray bursts.
Ultrafast dynamics and mechanisms of non-stationary absorption in thin gallium selenide samples
Authors: Tikhomirov S. A.
Published: April 2021

Herein, the dynamics and mechanisms of induced absorption in thin samples of gallium selenide under various excitation conditions are studied using femtosecond kinetic spectroscopy. We have registered several types of induced changes including induced absorption on free charge carriers (“hot” and thermalized electrons), bleaching and absorption due to the population of near-edge trap or exciton states, as well as rapid changes in the absorption of probing radiation in the region of the overlap of the exciting and probing pulses due to two-quantum two-frequency interband transitions. The time ranges of the relaxation processes are estimated. It is shown that when using relatively low-intensity long-wave excitation (790 nm), the resonant excitation of the near-edge states occurs mainly due to two-quantum two-frequency transitions followed by the formation of the dynamic equilibrium between bound and free electrons in the time range up to 5 ps. When electrons are excited deeply into the conduction band with the formation of hot free electrons and their subsequent thermalization to the bottom of the conduction band in the time range up to 1 ps, the population of the near-edge states and the establishment of the dynamic equilibrium between bound and free electrons is realized in the same time range (5 ps) as when they are excited “from below”.
Problems of application of standards in evaluation of microstructure of metals and alloys
Authors: Anisovich A. G.
Published: April 2021

The purpose of this work is to consider the problems of applying some standards containing reference scales of structures: 1763-68, 1778-70, 5640-68, 9391-80, 10 243-75, 13938.13-93, 22 838-77, 3443-87 (materials: oxygenated copper, pipe and structural steels, cast iron). It is shown that the normative base of standards for metallographic analysis is morally outdated. The main problem is the discrepancy between the increase in standards and real modern structures. Basically, microstructure standards use a magnification of 100 times, in particular, for the analysis of oxygenated copper, banding of the rolled metal structure, Widmanstätt structure, phosphide eutectic. The analysis of modern materials requires an increase of about 500...800 times. The magnification of 360…400 times, used in some scales, is also insufficient, in particular, for the analysis of structurally free cementite. Also, the quality of images of structures makes them difficult to use. A common disadvantage of the considered standard scales of structures is the absence of metrics in photographs, which does not correspond to the modern level of metallurgy and causes certain inconveniences when comparing structures. It is necessary to revise the standards governing the structure of metals and alloys. Research should be carried out to develop a new generation of standards based on the real structures of modern industrial alloys. It is also necessary to develop new methods of structure analysis. This applies primarily to analysis in image processing programs.

This article describes a device developed and manufactured on the basis of the Physical-Technical Institute of the National Academy of Sciences of Belarus, an induction hardening complex, and a range of parts suitable for processing. In addition, the article provides an example of the development of a technology for hardening parts from the moment a drawing of a part is obtained, indicating the required parameters of the hardened layer, until the determination of the technology of hardening, determining the type of inductor used and determining the necessary parameters of hardening, such as: size of the heating zone, size of the cooling zone, speed of mutual movement of the part and inductor, as well as the type and pressure of the quenching fluid. The article also presents examples of simulation results, various processes of heating and cooling parts using the UNIVERSAL 2D program, and offers an example of analysis of the data and possible ways to adjust the heating parameters in order to obtain the desired result, which allows to obtaining hardened layers of parts of the desired size and hardness. The importance of the stage of modeling of heating modes, especially in the case of large workpieces, is noted. Thus, the insufficient cooling rate of such parts can lead to warping, especially at a too high quenching temperature and heating depth. Self-tempering significantly affects the hardness values of the deep layers. Various combinations of heating modes for one type of parts are selected individually, according to the requirement of a customer and the type of generator used. The higher the depth of the heating zone, the higher the effect of self-tempering on the deeper layers is.
Non-equilibrium thermodynamics model for calculating diffusion fluxes under phase transformations in alloy steels
Authors: Bobyr S. V.
Published: April 2021

The phase transformations in alloyed iron-carbon alloys is largely related to diffusion of components, foremost to the carbon. For the analysis of diffusive processes in alloy steels, it is possible to use the mathematical methods of non-equilibrium thermodynamics. The equation for the diffusive fluxes of the system contains unknown in general case of coefficients activity of elements and vacancies, and their derivatives for to the concentrations, that extraordinarily makes it difficult being of values of cross coefficients. In the article a non-equilibrium thermodynamics methodology of calculation of diffusive fluxes at presence of two phases in alloy steels is described. It allows one to calculate both direct- and cross coefficients in the Onsager equations. Formulas for calculation of thermodynamics forces in the alloy steel – for iron, alloying element of substitution – chrome, of element of introduction – carbon and vacancies, are presented. Common expressions are suggested for calculation of cross-factors, motive forces and fluxes in the Onsager’s equations for a multicomponent thermodynamic system. The example of using the developed model to find changes in concentrations and diffusion fluxes over time is given. For the model system used, it was established that at the stage of predominant diffusion of carbon in the alloy steel, cementite inclusions with a size of about 18 nm are formed rather quickly (within ~ 200 s). The technique developed in the article allows one to perform diffusion kinetics calculations in multicomponent thermodynamic systems, which are also iron-carbon alloys and to control the size of the phases formed, for example, of carbide nanoparticles.
Sintering of composite materials for tool appointment, based on impact diamonds, under high pressure and temperatures
Authors: Senyut V. T.
Published: April 2021

The article presents the results of a study of composite materials based on diamond-lonsdaleite abrasive (DLA) and various binders (Fe–Ti mechanocomposite, silicon carbide SiC). A metal-matrix composite material with a multimodal nano- and microlevel structure, characterized by increased adhesion of diamond grains to the binder, is obtained on the basis of impact diamonds and a Fe–Ti nano-mechanical composite. It is shown that the use of impact diamonds in comparison with synthetic diamonds makes it possible to reduce the pressure of thermobaric treatment by 30–50 % at the same sintering temperatures. The use of Fe–Ti–DLA composites in the process of magnetic-abrasive polishing (MAP) makes it possible to increase the removal rate of material based on silicon by 1.5–2 times and reduce the processing time by 30 % compared to ferroabrasive powder (FAP) based on synthetic diamonds. The effect of adding of silicon carbide on the process of obtaining a superhard composite material impact diamond – SiC is investigated. It is found that adding of SiC helps to reduce the defectiveness of the material and increase the homogeneity of its structure in comparison with the material without adding of a binder. In this case, an increase in the content of SiC and Si also leads to an inversion of the structure type of the superhard composite from polycrystalline to matrix. It is found that the additional use of amorphous soot and boron affects the refinement of the matrix structure of the composite material due to the formation of boron carbide and secondary finely dispersed silicon carbide.

In the work, the authors investigated the possibility of using the results of analytical solutions of the linear differential equations of unsteady heat conduction with constant heat transfer coefficients to calculate the temperature of the material during heat treatment of leathers. Heat treatment of natural leathers as heat-sensitive materials is carried out under mild temperature conditions and high air moisture contents, the temperature does not undergo significant changes, and the heat transfer coefficients change almost linearly. When using analytical solutions, the authors made the assumptions that for small temperature gradients over the cross section of a thin body, the thermal transfer of matter can be neglected and for values of the heat and mass transfer Biot criteria less than unity, the main factor, limiting heat and mass transfer, is the interaction of the evaporation surface of the body with the environment; so, in solving the differential heat equation we can restrict ourselves to one first member of an infinite series. In this case, a piecewise stepwise approximation of all thermophysical characteristics with constant values of these coefficients at the calculated time intervals was applied, which made it possible to take into account the change in the transfer coefficients throughout the entire heat treatment process. Processing of experimental data showed that in low-intensity processes with reliable values of the transfer coefficients, it is possible to use the results of solutions of differential equations of unsteady heat conduction in heat transfer calculations. The results of the study of heat transfer during drying of leather confirm the laws of temperature change established experimentally. Together with experimental studies of drying processes, analytical studies are of great practical importance in the development of new methods for calculating heat and mass transfer in wet bodies.
Influence of water content of expanded clay on the reflection coefficient of electromagnetic shild
Authors: Borbot’ko T. V. , Savanovich S. E.
Published: April 2021

The regularities of the influence of the moisture content of expanded clay on the values of the reflection coefficient of electromagnetic radiation (EMR) of this material in the frequency range of 1–17 GHz have been established. The relationship between the size of fractions (pore size) of expanded clay and the operating frequency range of the EMR screen samples has been determined. It is shown that a twofold increase in the moisture content of expanded clay with fractions of 1…4 and 10…20 mm provides an extension of the operating frequency range of the EMR shield samples made on the basis of this material, with a decrease in the reflection coefficient of the test samples by 1.7 and 3 times, respectively. It was found that an increase in the moisture content of expanded clay from 19 to 40 % with a decrease in the size of its fractions from 10…20 to 1…4 mm and a pore size from 0.1…0.2 to 0.01…0.06 mm provides a decrease in the values of the reflection coefficient of EMR screen samples at frequencies of 7.7–17.0 GHz, and an increase in the size of expanded clay fractions from 1…4 to 10…20 mm with an increase in the size of its pores from 0.01…0.06 to 0.1…0.2 mm provides a decrease in the values of the reflection coefficient of EMR screen samples at frequencies of 1.0–7.7 GHz. It is shown that the practical use of these regularities makes it possible to form EMR screen samples with reflection coefficients from –2.8 to –22.0 dB in the frequency range 1–17 GHz, which makes it possible to recommend them for use when creating shielded rooms.
