Authors: MANUKYAN L.A. , HOVAKIMYAN V.V.
Published: December 2022

For volumetric physical modeling, the physical-mechanical and deformation prope¬r¬t¬ies of the equivalent material for 3D physical modeling by direct and triaxial shear equipment in laboratory conditions are determined. The results of laboratory tests showed an insig¬n¬i¬f¬i¬c¬ant difference between characteristics obtained from direct and triaxial shear tests. It has been found that the strength properties of the equivalent material, such as internal friction angle and cohesion, could be defined by modern, laboratory direct and triaxial equipment which possesses high susceptibility to small shear strains.

STUDYING THE EXTRUSION PROCESS OF A SINTERED THIN-WALL
PIPE LOADED WITH INTERNAL HIGH PRESSURE IN CASE OF A BOUNDARY CONDITION IN THE DIE INLET
Authors: BABAYAN A.A.
Published: December 2022

An analytical study of the process of sintered thin-wall pipe extrusion loaded with internal high pressure, on its cross section in the conical die inlet by compressing meridio¬n¬a¬l dimensionless stress has been carried out. It is assumed that the external die pressure p_v and the internal high pressure p_r acting on the pipe are equal. In this case, the circumferential stress is determined and a simplified plasticity condition is obtained. The dimensionless values of meridional, circumferential and average stresses depending on the degree of pipe deformation were determined, which made it possible to study the processes of their compaction using the DTPPM equations at different values of coefficients of friction and initial porosities of the pipe material.
A computer simulation of the process was carried out in the MS EXEL software environment, presetting different initial values of the compressive meridional dimensionl¬e¬s¬s stress. The pipe extrusion process will correspond to such an initial value of this stress, when the meridional stress of the pipe in the outlet of the die is equal to zero. In this case, the value of strain intensities is ε_i=0.258.
The graphs of changes in 10, 20 and 30% of the initial porosities of the material show that the porosity becomes zero in the interval of value of deformation intensities ε_i from 0.116 to 0.132, and also in the case of large values of porosities and contact friction, the compaction of the material occurs more intensively.
SUBSTANTIATING THE PROCESS OF PRODUCTION OF FERROMOLYBDENUM FROM TEGHUT MOLYBDENITE CONCENTRATE UNDER PRODUCTION CONDITIONS
Authors: ZAKARYAN E.G.
Published: December 2022

Studies of the production process of ferromolybdenum under industrial conditions feom Teghut molybdenite concentrate by using different reducing materials are carried out. Molybdenum can be reduced by carbon at low energy costs. However, the reduction of molybdenum oxides with carbon is accompanied by the formation of undesirable carbides Mo2C and MoCl-x. Due to the limitation of the carbon content in ferromolybdenum (≤0.05…0.5% C), it is obtained by the metallothermal method. In production, ferromolybde¬num is smelted by the out-of-furnace silicoaluminothermal method with an upper fuse from fired molybdenum concentrate (50.% Mo) and the use of ferro-silicon-aluminum (FSA) containing 60…65% Si and 10…12% Al, aluminum grains, iron ore, steel shavings and lime. The process takes place only due to the heat released by the reduction reactions of molybdenum, iron and other elements oxides with silicon and aluminum.
From the standpoint of thermodynamics, the reduction reaction of molybdenum oxides by the carbothermal method has a positive value of enthalpy and entropy (due to the formation of CO), the total value of the change in Gibbs energy (∆G_T^0) remains negative and becomes smaller in absolute terms. That is why carbohydrate recovery requires external energy expenditure. On the contrary, when reducing by the aluminothermic and silicothe¬r¬m¬ic methods, the reactions are too negative, since these reactions are highly exothermic, and here the entropy factor does not affect the negative value of the change in Gibbs energy (∆G_T^0) (all reactants and the resulting products are in solid form), therefore the reactions are recovered due to the exothermicity of their own reactions and do not require external energy costs, which is the potential advantage of this method.
A TECHNOLOGY TO REDUCE THE NEGATIVE EFFECT OF A MASS EXPLOSION ON OPEN PITS
Authors: AHARONYAN G.A.
Published: December 2022

The explosive preparation of rock for excavation at the open pit is always accompanied by such negative phenomena as the release of dust and gases, the formation of air and seismic waves, as well as the uncontrolled scattering of separate pieces of exploded rock. In this regard, when carrying out mass explosions at an open pit, it is necessary to limit the on above-mentioned negative effects of an explosion in the field area. A new technology of detonation is proposed to reduce the negative impact of an explosion by reducing the limiting pressure of gaseous products of explosives on the wall of the charging cavity. Using the example of the Aramus open pit, the possibility of regulating the degree of rock crushing and reducing the negative impact of the explosion is considered.

Published: December 2022

Aim: Methanol intoxication is rare and it can be fatal. This case report aimed to describe the radiological findings in acute methanol intoxication complicated with intracranial hemorrhage in a young patient. Case Report: A 32 year-old man applied to emergency department with a major complaints of nausea, vomiting, double vision, and confusion. Glascow coma score (GCS) was 7 at the initial referral. Laboratory tests showed high anion gap metabolic acidosis. Acute methanol intoxication was diagnosed by aid of the patient anamnesis. Diffusion-weighted MRI (DW-MRI) showed similar diffusion restriction lesions in the putamen and cingulate gyrus of both cerebral hemispheres. The patient had a cardiac arrest during follow-up in the emergency department. He was converted to sinus rhythm with the interventions, intubated, and taken to the intensive care unit. GCS reduced to 3 during follow- up at the 4th day. Cerebral intraparanchimal hemorrhage at the level of left basal ganglia was observed in the brain computed tomography (CT). He was operated however remained comatose after the operation and died at the 8th day of admission. Conclusion: Possibility of methanol intoxication should be included in the differential diagnosis in patients with altered consciousness, vision disturbances and a high anion gap admitted to the emergency service. DW-MRI may be helpful in diagnosis by detecting symmetrical diffusion restrictions at the basal ganglia. Additionally radiologic methods like CT can be used to determine complications such as bleeding that may occur during the follow-up of the cases.

Kárpátaljai fiatalok önkéntes tevékenysége a 2022-es orosz-ukrán háború idején
Authors: Pallay Katalin , Markos Valéria , Fényes Hajnalka
Published: December 2022

A 2022-es orosz-ukrán háború idején fontos szerep hárul a kárpátaljai fiatalokra, akik önkéntesként segítik a menekülteket Kárpátalján, az ukrán-magyar határon és Magyarországon. A narancsos forradalom és a Majdan téri tüntetéssorozat következtében jelentősen nőtt az ukrán lakosság civil aktivitása, illetve Kárpátalján a magyar kisebbségi lét is felerősítette a civil részvételt az ezredforduló után. Kutatásunk célcsoportját indokolja, hogy Ukrajnában a fiatalok alkotják az önkéntesek legnagyobb csoportját. Feltáró kutatásunkban félig strukturált interjúkat készítettünk kárpátaljai fiatal önkéntesekkel, melynek során azt vizsgáltuk, hogy milyen háború előtti önkéntes tapasztalatokkal rendelkeztek, mi jellemző a háború alatti önkéntes tevékenységükre, mi motiválta őket azönkéntességre, és milyen formában térülhet meg számukra. Az interjúk mentén témaanalízis mellett típusanalízist is készítettünk, melynek során három önkéntes-típust határoltunk körül (altruista motivációjú rendszeres önkéntesek, vegyes motivációjú rendszeres önkéntesek és vegyes motivációjú alkalmi önkéntesek). Kutatásunk legfontosabb eredménye, hogy a háború következtében kialakuló társadalmi feszültség ellenére a kárpátaljai önkéntes fiatalokra erős szolidaritás a jellemző az ország belsejéből érkező ukrán menekültekkel kapcsolatban. Másik fontos következmény lehet, hogy az interjúalanyok azon csoportja, akik csak a háború idején kezdtek el önkéntes tevékenységet végezni, feltehetőleg a jövőben is nyitottak lesznek mások megsegítésére, melynek következtében még inkább terjed az önkéntesség kultúrája a vizsgált térségben.

Published: December 2022

Employee performance appraisal aims to find employees with good performance qualities in accordance with the vision and mission of the Ministry of Law and Human Rights. The difficulty that occurs in conducting the employee performance appraisal process is the difficulty of selecting employees properly and fairly due to the diversity of educational backgrounds, experiences, competencies and portfolios in which it becomes a concern in determining outstanding employees. To overcome these obstacles, a decision support system for the MAUT method is needed to be used as an additional medium to support the decision-making process. The implementation of the system uses the Visual Basic 2010 programming language and the method used in this study is the Waterfall Method. From the results of the
tests carried out, it can be concluded that employee performance appraisal by MAUT can be done well by ranking, where the highest value is 0.76 and the lowest value is 0.09 from the MAUT ranking process which can then be reported in the form of an employee performance report.
