MOBILIZATION AND MANNING OF THE RED ARMY DURING THE CIVIL WAR IN RUSSIA (1918-1922)
Authors: Makarevich O. L.
Published: September 2020

The article is devoted to the analysis and generalization of the experience of mobilization work of the military administration of the Red Army, received during the Civil War 1918-1922. Historically short period of time is unique in that under emergency conditions of war and economic ruin, in the ring of fronts against the white armies and foreign troops of the interventionists, the Soviet leadership managed to create and establish an overall effective mechanism for manning the Red Army troops. The article considers the evolution of the main mobilization body - the Mobilization Department (since September 1918 - Management) of the all-Russian General staff. The role of so called “military experts” - former officers and Joint Staff generals who often held similar positions in the mobilization bodies of the old army - in the correct formulation of mobilization work is emphasized. The article shows the features and results of registration and mobilization work, expressed in various ways of staffing troops with human resources: general and private appeals, identification and legalization of deserters, unscheduled military (local) mobilization. Explanations are given for the dominance of certain methods of recruiting troops at various stages of the Civil war.

Published: September 2020

In accordance with the requirements of construction standards, building structures should be designed taking into account their protection against accidental actions, such as gas explosions or car accidents. The current standards are largely inconclusive and quite enigmatic, there is also a deficiency in literature studies describing the issue. The article presents the basic procedures of design of the reinforced concrete buildings, including the requirements of the PN-EN 1991-1-7:2008 and the results of the calculations and analysis for a sample flat slab, whose structure meets the requirements of protection against the phenomenon of progressive collapse.

Published: September 2020

This paper presents a methodology of dimensioning of double reinforced concrete beams which are reinforced in the light of the requirements of the EC2 [1] in two variants. In the first variant, the limiting value of the compression zone was determined on the basis of limiting strains of concrete and steel. The maximum degree of concrete reinforcement of bending elements are assumed in the second case. The considered problem is illustrated by computational examples in relation to the concrete classes C30/37 and C70/85. Results of the calculations cannot be the basis for generalizations, however, differences in the section of the reinforcement determined in both cases are small and do not exceed 6%.
Objects for storing fruits, vegetables or potatoes
Authors: Chądzyński Andrzej , Piróg Marek
Published: September 2020

Properly designed and implemented specialized storage objects guarantee specialist storing of the discussed group of agricultural products. They make independent the whole process of  storage, improving and the trade of goods from conditions of the outside climate. Storage spaces and cold stores are currently a highly specialized group of objects of the food industry infrastructure. The program of the designed object  constitutes the basis for the forming of its functional arrangement and the form of the object. In the storage building it is subordinate to the technology and the functional and spatial arrangement of the building follows the arrangement of the technological thrust. The object being a casing of the technological process of storing should form a possibly closed and tight microclimatic space and the building partition system along with an air-conditioning units should enable to keep adequate parameters of the interior microclimate on a particular level. The factors of the microclimate influencing the storage conditions are: temperature, relative humidity of air, gas composition of the atmosphere surrounding agricultural products and the air movement in the storage space.

Hydrophilicity as a measure of the efficiency of the superplasticisers
Authors: Janowska-Renkas Elżbieta
Published: September 2020

This paper presents the results of chemical structural investigations of four new-generation superplasticizers (denoted here as SP-A through SP-M2) used in concrete production engineering. The commercial product samples, the gel permeation chromatography (GPC) and the Fourier-Transformed Infrared Spectroscopy (FTIR) test methods were applied to the research. The effect of superplasticizers on the rheological properties of cement pastes was tested. The performance of a superplasticizer, i.e. the reduction of plastic viscosity, was demonstrated to be enhanced by:  hydrophilicity of the SP polymer –understood as the ratio of hydrophilic ethers to hydrophobic esters in the polymer chain, SP polymer content in the bulk of the commercial product sample, weight-average molecular weight (Mw) of the SP polymer. The above relations were confirmed for  the studied superplasticizers– the derivatives of: acrylic acid (SP-A1 and SP-A2) and maleic acid (SP-M2 and SP-M1). The efficiency of superplasticizers was found to decrease with the contents of the free poly(ethylene glycols) (PEGs) which remained unreacted with acids and/or anhydride. The superplasticizers based on the maleic anhydride derivatives (SP-C and SP-D) proved to be more efficient and to slow down the hydration process to a much higher extent than the superplasticizers – acrylic acid derivatives (SP-A1 and SP-A2).

The influence of rotational flexibility of beam-column connection on roof plane rigidity of energy-active cover of frame-purlin hall
Authors: Brzezińska Karolina , Szychowski Andrzej
Published: September 2020

The paper analyses the influence of the rotational flexibility of beam-column connection on the roof plane rigidity of the longitudinally braced frame-purlin cover of the solid wall hall. The cover is adapted to obtain thermal energy from solar radiation. The roof cover is then provided in the form of a transparent glass barrier which requires considerable roof plane rigidity. The analysis aimed to compare the roof plane rigidity of the frame-purlin cover to those of space structures and truss-purlin covers, depending on the type of longitudinal bracing and rotational rigidity of the beam-column connection. The investigations were conducted for three types of roof plane bracing and different rigidity indexes of the beam-column connection (from u=0 – pin connection, through u=0.25; 0.5; 0.75 – semi-rigid connection, to u=1 – rigid connection). In the transfer of horizontal forces, the interaction of the rigidity of frames with flexible nodes (beam-column) with longitudinal roof plane bracings supported by lateral bracings of gable walls was observed. The highest roof plane rigidity was demonstrated by 2X-shaped and K-shaped braces with rigid nodes at frame corners.

Labor demand as a key factor in building process planning
Authors: Marcinkowski Roman
Published: September 2020

Man or machine hours needed by various resources to complete construction works are the basis for work estimation and scheduling. In particular, they enable the planner to estimate labor costs or time needed to complete the task, review the resource of workload and availability of resources assigned to particular task, check the possibility of sharing resources across various tasks and determine other rates and factors useful in works scheduling. The project schedule can be analyzed both without or with and in consideration of risk of the end date of the project being pushed out or going over budget on the project. Issues presented above are the subject of this paper. The methods of solving described problems consider the optimization of a loss that derives from partial utilization of assigned the resources.
The method of analysis of a reinforced concrete section under bending in the post-yield range
Authors: Korentz Jacek
Published: September 2020

Predicting the behavior of plastic hinges subjected to large inelastic deformations caused by extreme loads such as earthquakes plays an important role in assessing maximum stable deformation capacities of framed concrete structures. This paper presents an analytical procedure for analysing the behaviour of a reinforced concrete section under bending in the post-yield range. The following stages of section behaviour are defined as the uncracked; first cracked; yielding; cover crushing; cover spalling; buckling of bars; and limit stages. The relationship between the moment and curvature in these stages, including the effects of concrete confinement, the spalling of the concrete cover, and the inelastic buckling of the reinforced bars, are considered. The results obtained from analytical calculations have are compared to the results obtained from a computer analysis. The presented method makes it possible to estimate the ductility of reinforced concrete members with various longitudinal and transverse reinforcement.

3D Quantum-inspired Self-supervised Tensor Network for Volumetric Segmentation of Brain MR Images
Authors: Konar Debanjan , Bhattacharyya Siddhartha , Gandhi Tapan Kumar , Panigrahi Bijaya Ketan
Published: September 2020

This paper introduces a novel shallow self-supervised tensor neural network for volumetric segmentation of brain MR images obviating training or supervision. The proposed network is a 3D version of the Quantum-Inspired Self Supervised Neural Network (QIS-Net) architecture and is referred to as 3D Quantum-inspired Self-supervised Tensor Neural Network (3D-QNet). The underlying architecture of 3D-QNet is composed of a trinity of volumetric layers viz. input, intermediate and output layers inter-connected using a 26-connected third-order neighborhood-based topology for voxel-wise processing of 3D MR image data suitable for semantic segmentation. Each of the volumetric layers contains quantum neurons designated by qubits or quantum bits. The incorporation

of tensor decomposition in quantum formalism leads to faster convergence of the network operations to preclude the inherent slow convergence problems faced by the self-supervised networks. The segmented volumes are obtained once the network converges. The suggested 3D-QNet is tailored and tested on the BRATS 2019 data set extensively in the experiments carried out. 3D-QNet has achieved promising dice similarity while compared with the intensively supervised convolutional network-based models 3D-UNet, Vox-ResNet, DRINet, and 3D-ESPNet, thus facilitating annotation free semantic segmentation using a self-supervised shallow network.

Published: September 2020

A dermatomiosite canina é uma vasculopatia inflamatória da pele e músculos, com manifestações cutâneas envolvendo a face, orelhas, extremidades da cauda e distais por sobre proeminências ósseas. O envolvimento muscular manifesta-se sob a forma de mioatrofia cefálica, dificuldade de deglutição, redução do reflexo do vômito e marcha atípica. A dermatomiosite canina é classificada em dermatomiosite canina familiar e em forma variante ou dermatomiosite-símile. Neste relato descreve-se um caso de dermatomiosite-símile em cadela de dois anos de idade, sem raça definida, que apresentava necrose isquêmica dos pavilhões auriculares e atrofia dos músculos temporal e masseter. O exame dermo-histopatológico realizado em fragmentos de pele dos pavilhões auriculares, região cefálica e amostras de tecido muscular (temporal e masseter) confirmou a existência de dermatite perivascular e foliculite de interface pobre em células, focos de atrofia folicular e de fibras musculares e moderada fibrose dérmica. Portanto a histopatologia, associada às manifestações clínicas do animal, permitiu o estabelecimento do diagnóstico de dermatomiosite-símile, enfermidade pouco descrita na dermatologia veterinária brasileira.

Medical Assistance in Dying in health sciences curricula: A qualitative exploratory study
Authors: Brown Janine , Goodridge Donna , Thorpe Lilian
Published: September 2020

Background: This paper offers insight into (1) the driving and restraining forces impacting the inclusion of medical assistance in dying (MAID) in health sciences curricula, (2) the required resources for teaching MAID, and (3) the current placement of MAID in health sciences curricula in relation to end-of-life care concepts.

Method: We conducted a qualitative exploratory study in a Canadian province using Interpretive Description, Force Field Analysis, and Change as Three Steps. We interviewed ten key informants (KI), representing the provincial health sciences programs of medicine, nursing, pharmacy, and social work. KIs held various roles, including curriculum coordinator, associate dean, or lecturing faculty. Data were analyzed via the comparative method using NVivo12.

Results:  Curriculum delivery structures, resources, faculty comfort and practice context, and uncertainty of the student scope of practice influenced MAID inclusion. Medical and pharmacy students were consistently exposed to MAID, whereas MAID inclusion in nursing and social work was determined by faculty in consideration with the pre-existing course objectives. The theoretical and legal aspects of MAID were more consistently taught than clinical care when faculty did not have a current practice context. Care pathways, accreditation standards, practice experts, peer-reviewed evidence, and local statistics were identified as the required resources to support student learning. MAID was delivered in conjunction with palliative care and ethics, legalities, and professional regulation courses.

Conclusion: The addition of MAID in health sciences curricula is crucial to support students in this new practice context. Identifying the drivers and restrainers influencing the inclusion of MAID in health sciences curricula is critical to support the comprehensiveness of end-of-life education for all students.
Chromatic Vertex Folkman Numbers
Authors: Xu Xiaodong , Liang Meilian , Radziszowski Stanisław P.
Published: September 2020

For graph $G$ and integers $a_1 \ge \cdots \ge a_r \ge 2$, we write $G \rightarrow (a_1 ,\cdots ,a_r)^v$  if and only if for every $r$-coloring of the vertex set $V(G)$ there exists a monochromatic $K_{a_i}$ in $G$ for some color $i \in \{1, \cdots, r\}$. The vertex Folkman number $F_v(a_1 ,\cdots ,a_r; s)$ is defined as the smallest integer $n$ for which there exists a $K_s$-free graph $G$ of order $n$ such that $G \rightarrow (a_1 ,\cdots ,a_r)^v$. It is well known that if $G \rightarrow (a_1 ,\cdots ,a_r)^v$ then $\chi(G) \geq m$, where $m = 1+ \sum_{i=1}^r (a_i - 1)$. In this paper we study such Folkman graphs $G$ with chromatic number $\chi(G)=m$, which leads to a new concept of chromatic Folkman numbers. We prove constructively some existential results, among others that for all $r,s \ge 2$ there exist $K_{s+1}$-free graphs $G$ such that $G \rightarrow (s,\cdots_r,s)^v$ and $G$ has the smallest possible chromatic number $r(s-1)+1$ with respect to this property. Among others we conjecture that for every $s \ge 2$ there exists a $K_{s+1}$-free graph $G$ on $F_v(s,s;s+1)$ vertices with $\chi(G)=2s-1$ and $G\rightarrow (s,s)^v$.

Authors: D'haeseleer Jozefien , Van de Voorde Geertrui
Published: September 2020

In this paper, we study translation hyperovals in PG(2,qk). The main result of this paper characterises the point sets defined by translation hyperovals in the André/Bruck-Bose representation. We show that the affine point sets of translation hyperovals in PG(2,qk) are precisely those that have a scattered F2-linear set of pseudoregulus type in PG(2k−1,q) as set of directions. This correspondence is used to generalise the results of Barwick and Jackson who provided a characterisation for translation hyperovals in PG(2,q2), see [S.G. Barwick, Wen-Ai Jackson, A characterization of translation ovals in finite even order planes. Finite fields Appl. 33 (2015), 37--52.].
Frameworks for Two-Dimensional Keller Maps
Authors: Borisov Alexander
Published: September 2020

The classical Jacobian Conjecture asserts that every locally invertible polynomial self-map of the complex affine space is globally invertible. A Keller map is a (hypothetical) counterexample to the Jacobian Conjecture. In dimension two every such map, if exists, leads to a map between the Picard groups of suitable compactifications of the affine plane, that satisfy a complicated set of conditions. This is essentially a combinatorial problem. Several solutions to it ("frameworks") are described in detail. Each framework corresponds to a large system of equations, whose solution would lead to a Keller map.
Linked Partition Ideals, Directed Graphs and $q$-Multi-Summations
Authors: Chern Shane
Published: September 2020

In this paper, we start by considering generating function identities for linked partition ideals in the setting of basic graph theory. Then our attention is turned to $q$-difference systems, which eventually lead to a factorization problem of a special type of column functional vectors involving $q$-multi-summations. Using a recurrence relation satisfied by certain $q$-multi-summations, we are able to provide non-computer-assisted proofs of some Andrews--Gordon type generating function identities. These proofs also have an interesting connection with binary trees. Further, we give illustrations of constructing a linked partition ideal, or more loosely, a set of integer partitions whose generating function corresponds to a given set of special $q$-multi-summations.
Gaussian Circular 2D FIR Filters Designed Using Analytical Approach
Authors: Matei Radu
Published: September 2020

This paper proposes an analytical design procedure for a particular class of 2D filters, namelyGaussian-shaped, circularly-symmetric FIR filters. We approach both low-pass and band-pass circular filters,which are adjustable in selectivity and peak frequency. The design starts from a given 1D Gaussian prototypefilter, approximated using the Chebyshev series. A frequency transformation is applied to derive the circularfilter. Several design examples are provided for both types of filters. The filters designed through this methodare efficient, their frequency response results in a factored or nested form, convenient for implementation.
The Influence of Collaborative Innovation Among Technology ,Institution and Finance on China’s Economic Growth
Authors: Ting Li , Xin Chen Qiu , Qian Ye Qian
Published: September 2020

This paper constructs a model of collaborative innovation among technology, institution and financeto measure the synergy degree of 29 provinces and cities. Official provincial-level panel data from 2011-2017for 29 provinces are utilized. We find that there is a great difference in the synergy degree among differentregions because of the uneven distribution of financial resources in the region. Then the synergy degree of 29provinces and cities in China is regarded as an important variable in the fixed-effects model. The primaryfinding is that the degree of collaborative innovation among technology, institution and finance can positivelyaffect China’s economic growth. If the degree of collaborative innovation increase by 1%, and the GDP percapita will also increase by about 0.009%-0.016%. However, the domestic loan index of real estate enterpriseshas a negative impact on the per capita GDP. Then we get the conclusion that collaborative innovation will beeffective for China’s high-quality economic growth and suggest that government should use macro control toreduce capital’s preference for real estate investment especially by strengthening direct financial innovation tosupport technological innovation.

Thermal deformation and the loss of stability during plasma cutting of metal
Authors: Vintsiv Anna N. , Burmistrov Evgeny G.
Published: September 2020

The article deals with the condition of metal sheets in plasma cutting process. The initial dependence of the deformation value on the length of the sheet metal L, the cutting width H, and the cutting speed is described. Furthermore, a new dependence of the strain value on the current, voltage, and material properties is derived from this formula. At the end of the article some ways of dealing with thermal deformations of a metal sheet that occur during plasma cutting are shown such as eliminating the stress state of metal sheets, the ratio of the linear dimensions of the part to its thickness. The technique of fixing metal sheets to the cutting table, reducing waste after cutting, the effect of cutting speed on thermal deformations, the position of the sheet during cutting and uniform heating of the sheet are described.

One of the problems in the hovercrafts design is to dtermine the aerodynamic charactreistics of the wing near the earth surface. In this article, 4 methods for calculating the induced drag coefficient Cxi of a simple airfoil with an end plate at different relative heights were considered. Four methods of induced drag coefficient determination were considered for different relative flight’s heights. Calculations were performed according to the Phillips, Wieselsberge, Panchenkov-Surzhik, Mantle methods for the TsAGI-876 wing profile. The calculated values of induced drag coefficients were compared with the experimental wind tunnel’s data at the Central Aerohydrodynamic Institute.

The present study provides a designing the floating buoy system. The floating buoy is designed to determine the mid-frequency hydroacoustic set location, located in the underwater position, using sonar communication signals. The approach considers the stability at large angles of inclination analysis. For this reason, the main stability criteria is recovery moment. As a result, the following diagrams are plotted – statical stability curve and dynamical stability curve to estimate the research. Moreover, the study includes defining spatial configuration at steady flow. It is also important to mention the basic requirements for the construction of the buoy are ensuring positive buoyancy according to the terms of reference, lack of sea water absorption, sustainability to hydrostatic pressure and corrosion resistance. The study reveals designing the construction, which is able to prevent capsizing. Consequently, the buoy has positive stability, sufficient recovery moment enable to return the structure to its original position and meet the claimed buoyancy requirements.

Methods: A cross-sectional descriptive study of types- 2 diabetic patients at the Medical outpatient clinic in UCH was done with a validated structured 48 item self-administered questionnaire that measured the socio-demographics, knowledge, practice of and attitude to lifestyle modifications. A purposive sampling of 99 consenting patients out of 103 determined with Yaro Tamane formulae was done.  Data were entered into SPSS v. 21 for descriptive and inferential analysis.

Results: About 59.6% of respondents were within ≥60 years age range, and 68.7% of them were females. Many (51.5%) of them had tertiary education qualifications. On knowledge of symptoms, the majority 78 (78.8%) had good knowledge and 21(21.2%) had poor knowledge of diabetes mellitus. While 64 (64.6%) respondents had a good attitude and 35(35.4%) had a poor attitude towards lifestyle modification. Besides, a vast majority (94.9%) reported that lifestyle modification helps attain normal blood glucose levels, preserves life, assuage symptoms, and avert extended complications. The respondents tend to strongly agree to have a good practice of lifestyle modification with a weighted mean of 3.76 to 4.69 on a 5point scale.

Conclusion: The majority of the respondents had good knowledge, the practice of and attitude to lifestyle modification which can help patients in altering long-term habits, eating or physical activity, and maintaining these practices as part of the management of the disorder.

Authors: Hussain Irshad
Published: September 2020

Introduction: The world has been facing the pandemic COVID-19. This article highlights the importance of Hydroxychloroquine (HCQ) and Chloroquine (CQ) in the chemoprophylaxis of malaria during the pandemic COVID-19.

Objective: To derive logical conclusion about the indicated use of HCQ/CQ in malaria during the pandemic COVID-19.

Methods: Relevant research articles were retrieved. The online reports, research articles from google, google scholar and PubMed databases were searched and analyzed.

Results: HCQ and CQ are indicated for Malaria and its prophylaxis. The drugs are not silver bullets versus the COVID-19. The available clinical data till the end of July 2020 can be sufficient for the health authorities of various countries to stop using HCQ/CQ to treat COVID-19 patients.  The drugs are indicated for malaria instead. Malaria, a potentially deadly parasitic disease in the poorest countries which cannot even afford its preventive measures with HCQ/CQ and other drugs. Misuse of available drugs of Malaria can worsen the disease in the Africa and some Asian countries. The World Health Organization has recommended continuing chemo-prophylactic efforts for malaria during the COVID-19 crisis. Malaria and COVID-19 have certain common symptoms such as fever, headache and body pain which doubles the risk through misleading diagnosis by considering COVID-19 patients as malaria patients and vice versa. WHO has recommended the mass distribution of antimalarial drugs for these counties, so that malaria could not make COVID-19 more deadly.

Conclusion: Use of CQ/HCQ may be continued for the chemoprophylaxis of Malaria during the pandemic COVID-19 and the drugs may not be considered as Silver bullet for COVID-19. Directions of FDA and WHO may be complied regarding use of CQ/HCQ.
