Published: November 2022

Abstract
Mentoring programs developed at universities are an effective method of supporting student development. The participation in these programs brings them many benefits. These benefits include increased prestige in the community, gaining new experiences and achieving defined goals in the case of universities. It is essential to improve the mentoring programs implemented at universities. This article presents the results of research carried out within the framework of the BEGIN project implemented and funded under the Erasmusplus program. The aim of the research was to identify academic staff's experiences of participating in formal and informal mentoring programs. Ten in-depth interviews were conducted with respondents from Italy, Poland and Germany. A purposive selection method was used. The research provided clues with a practical dimension on how to implement mentoring programs, usefulness from the student's point of view, effectiveness and efficiency, and how to measure the impact of the program on students.

Published: November 2022

Abstract

Background: Psoriasis is a common, inflammatory immune-mediated dermatosis, occurring in patients of all ages, sexes, and races, associating significant comorbidities. One such comorbidity is represented by psychological disorders, which negatively influence the clinical course of the disease. The purpose of our study is to offer a first glimpse into the stigmatization of Romanian psoriasis patients, as well as their potential anxious or depressive manifestations.

Materials and methods: The present study is based on an adapted questionnaire previously used to estimate stigmatizing attitudes in the general population, mirrored to reflect the patients’ experience in social situations such as shaking hands, maintaining friendship, kissing, or intercourse. GAD7 and PHQ8 scales were used to screen for anxiety or depression traits in the same patients.

Results: Our study group consisted of 12 psoriasis patients, with a mean age of 46.75 years. While few patients reported feeling discriminated against in social contexts, 16.66% presented with mild depressive symptoms recorded by PHQ8 and 24.99% presented mild anxiety manifestations according to their GAD7 scores.

Conclusion: In spite of the small sample group, our study outlines a tendency for depressive and anxious manifestations in patients with psoriasis.
The Circadian Axis and Cardiometabolic Syndrome

Published: November 2022

Abstract
Circadian rhythm refers to the daily physiologically fluctuating patterns of systemic processes that occur within a circa 24-hour timeframe, independently of external factors. There is evidence that in time, external and internal cycle misalignment leads to severe health consequences, resulting in the development of cardiometabolic disturbances. Desynchronized hormonal fluctuations along with daily specific macronutrient utilization patterns are also discussed, which by consequence, are all predictors of metabolic syndrome. The aim of this paper is to provide insight on the circadian clock’s organization throughout the human body and to explain the underlying genetic background. By understanding these well-established molecular mechanisms and processes, we believe this paper will provide accuracy regarding the importance of the circadian clock’s integrity and will highlight its role in the etiopathology of cardiometabolic syndrome.
On the construction of the elementary trigonometric functions
Authors: Medvegyev Péter 
Published: November 2022

Abstract
The article discusses the construction of the elementary trigonometric functions. It discusses several approaches, but the main message is that to construct the trigonometric functions one needs to follow the same approach as one should use during the construction of the real exponential function, but one should use complex numbers. The key point is that one must construct the complex square root function to define the trigonometric functions on the binary numbers and then one should use some convexity argument to prove their differentiability. This approach, as the power series approach, based on the intimate relation between the trigonometric and the exponential functions.
Monitoring of population systems

Published: November 2022

Abstract
This is a selected overview of a research line initiated and mostly developed by the three authors over the last three decades. Applying the state space paradigm of Mathematical Systems Theory, monitoring means that from the observation (a transform) of an unknown state process, the latter should be recovered. Since most of the dynamic models of population biology are nonlinear, for solving the monitoring problem, tools of nonlinear analysis are applied in different contexts. This approach to monitoring has found different applications ranging from population ecology to radiotherapy, from stock estimation in fisheries to monitoring of solar thermal heating systems.

Abstract in English
Cast aluminium alloys are commonly used in the automotive industry for casting applications. There are both primary and secondary/recycled aluminium alloys in the market, which differ in price and quality. In this study, the effect of alloy quality on solidification, microstructure and mechanical properties was investigated. The comparison of properties was carried out in the as-cast condition and in the heat-treated condition. The influence of alloy quality on solidification was analysed by simple thermal analysis and differential scanning calorimetry, and thermodynamic simulations. The basic mechanical properties analysed were tensile strength, yield strength, elongation, and hardness. The microstructural differences were analysed using a light microscope. The Mn:Fe ratio, which is strongly influenced by the alloy quality, was found to have a pronounced effect on the mechanical properties, while magnesium together with silicon hardens the aluminium matrix during heat treatment, which significantly increases the mechanical properties. This research proved that thermal analysis methods can give us a necessary and important indication of the quality of the alloys used.

Abstract
This work is interested in studying the vibrations’ stability in gas turbines, compared to a dynamic model of the Jeffcott rotor, the parameters of the gas turbine will be estimated for the purpose of developing a mathematical model which points out the behavior of the turbine rotor in virtue of the data of actual vibration measurements. The addition of the geometric nonlinearities of the vibrations unveils a supercritical Hopf bifurcation, the unstable modes are repulsed towards a stable limit cycle of small radius. The vibration measurements and analyzes were performed on a gas turbine Solar TITAN 130 type mounted in a gas compression station in Djelfa, Algeria. The turbine was in the operating mode when the vibration parameters were read. Bifurcation monitoring bounds the specific operating ranges, extracts efficiently the dynamic behavior core of the studied turbine and consequently affords a new approach to efficiently dimension the turbine rotor.

Published: November 2022

Abstract
The ranking results of the alternatives are heavily influenced by the decision making method, data normalization method, and calculation method for criterion weights. In this study, five multi-criteria decision-making methods were compared: MABAC, COCOSO, MAIRCA, VIKOR, and ROV. All of these methods use the same data normarmalization method. The weights for the criteria were determined using four methods: Equal, ROC, RS, and Entropy. In two different examples, the combination of multi-criteria decision-making methods with weighting methods for ranking alternatives is demonstrated. In each example, the number of options and the number of criteria are also different. The results in both examples show that regardless of the weighting method, multi-criteria decision-making methods always determine the same best solution. Furthermore, the direction of future research has been mentioned in the final section of this paper.

Published: November 2022

Abstract
When performing calculations of any technological equipment or processes, one works with different types of equations. Equations can be written in various forms, while in the older literature one can also encounter equations that are dimensionally non-homogeneous. The article deals with the modification of non-homogeneous equations into a form that allows direct substitution of the values of physical quantities in a chosen coherent system of units. The procedure for adjusting the relationship is shown on the equation allowing to determine the height equivalent of the theoretical plate.

Published: November 2022

Abstract
The reasons for decreasing the well operating parameters of depleted gas condensate fields have been analysed. A new approach has been proposed, which involves restoring the wells productivity by creating foam by means of a device developed for removing liquid from the well bottom. The expediency of using foam has been experimentally investigated for gas condensate wells to be completed and their productivity to be recovered. Techniques for removing liquid contaminants from wells have been developed, which involve injecting non-explosive gas mixtures and foams of various volumes into wells. Computational fluid dynamics modelling of the operation of the device for the wells completion with foam was carried out. The influence of the mass flow rate of an aqueous solution at the inlet to the device on the distribution of volume fraction of the gas and liquid phases, and the quality of the foam has been investigated. The understanding of the regularities of foam destruction processes by hydrocarbon condensate was obtained, and a device design was developed for the complete foam destruction.
Electricity Consumption and Economic Growth in WAEMU Countries: an Empirical Analysis using Panel Data
Authors: Moussavou Ferdinand 
Published: November 2022

Abstract
This paper analyzes the relationship between electricity consumption and economic growth, as well as the determinants of this relationship, in the countries of the West African Economic and Monetary Union (WAEMU) over the period from 1990 to 2018. The results obtained from the Autoregressive Lagged Model (ARDL) show that, in the long run, economic growth, the degree of international openness, and gross fixed capital formation explain electricity consumption. In the short run, no variable affects this consumption. Furthermore, in the country-by-country model, the results indicate differentiated effects. They show, in the long and short term, the absence of the effects of economic growth on electrical energy consumption.

Published: November 2022

Abstract
Beyond international accounting standards, which recognize that there have been significant investments in intangible assets in recent decades and have complaints that do not identify investments in intangible assets in financial statements, distorts the assessment of companies’ performance and does not allow for a fair evaluation of the market value of them, there are also numerous recent studies that confirm this. In today’s knowledge economy, we find that the information provided by recent financial statements needs to be more sufficient for stabilizing strategies, decision-making, and the stability of the actual market value of companies. This article proposes a critical analysis of the current financial statements and how they manage to provide or imagine faithfully to complete the market value of the companies.

Patchouli (Pogostemon cablin Benth) is a perennial aromatic crop that can produceessential oil which is generally used as a mixture of ingredients for making cosmetics, pharmaceuticals, and aromatherapy which functions as a binder/fixative agent and pharmaceuticals. Although the production of patchouli increases year to year, the productivity per hectare of this plant showed a decreasing pattern. Efforts are needed to increase the productivity of patchouli, such as improving seeds quality and applying best management practices in planting. This study aimed to examine the optimum application of manure doses and intercropping practice on maximum growth of patchouli at first and two months after planting. The RCD (Randomize Complete Design) was conducted by using a cropping system and the application of goat manure in different doses. There were two levels of the cropping system: monocropping and intercropping with mung beans (Phaseolus radiatus) and four-level of manure in different doses were applied, 0 g, 500 g, 1000 g and 2000 g. ANOVA analysis shows that no interaction between cropping system and manure application on the growth of patchouli. All variables of patchouli growth in monocropping are better than in intercropping at two months after transplanting. Furthermore, there was no effect of manure application on canopy width, fresh and dry biomass of patchouli. The effect is only found on plant height and tree basal diameter, while without manure application and 500 g application is greater than 1000 g and 2000 g of manure application.

Published: November 2022

Purpose. To analyze the publications related to the technique of MRI mapping of cerebrovascular reactivity.Materials and methods. We have analyzed 75 publications (4 Russian, 71 foreign), published in the period from 1960 to 2021 years. More than half of these articles were published in the last ten years, with 26 studies – in the period from 2016 to 2021 years.Results. The article systematizes methods for assessing cerebrovascular reactivity and approaches to assessing cerebrovascular reactivity by MRI. The technique of non-enhanced MRI mapping of cerebrovascular reactivity with a hypercapnic challenge is described in detail; alternative vasoactive stimuli are also considered. Issues related to data processing and evaluation of research results were discussed.Conclusion. Impairment of cerebrovascular reactivity plays an important role in the pathogenesis of cerebrovascular diseases. Over the past decades, various radionuclide and ultrasound methods have been widely used to assess cerebrovascular reactivity. In recent years the interest of researchers in MRI as a method of mapping cerebrovascular reactivity has increased significantly. Noninvasiveness, safety, absence of radiation exposure, and good tolerability are the absolute advantages of MRI mapping over other methods of assessing cerebrovascular reactivity. However, the variety of methodological approaches to MRI mapping of cerebrovascular reactivity causes significant variability in the results of the study. Standardization of the procedure should be the first step toward the introduction of MRI mapping of cerebrovascular reactivity into clinical practice.

Reconstruction of petrophysical zoning of the Blagodatnoye gold deposit in the Yenisei Ridge: Geodynamic and physical-chemical aspect
Authors: Kolmakov Yu. V. , Sazonov A. M. 
Published: November 2022

Research subject. Petrophysical zoning of the Blagodatnoye gold-sulﬁde deposit in the Yenisei Ridge. Aim. To determine indicative petrophysical characteristics of the products of the main occurrence stages and to develop an evolutionary petrophysical model of the investigated deposit.Materials and methods. Physical ﬁelds were studied by the methods of magnetic and electrical exploration and gamma-spectrometry. The petromagnetic heterogeneity and mineralogical-geo chemical features of formation of polymetamorphic complexes, metasomatites and ores were studied by a neutron activation analysis of the content of rare earth and radioactive elements, petrochemical x-ray ﬂuorescence analysis, as well as by an electron-probe microanalysis of pyrite.Results. The syncollisional fold-overthrust fault (785 Ma) of the preparatory stage provided structural control over the ore-bearing mineral-forming system. The signs of zone dislocation metamorphism include geophysical anomalies: magnetic and natural electrical anomalies due to pyrrhotite and graphite mineralization of cleavage zones on fold limbs, and speciﬁc electrical resistance from siliciﬁcation zones in fold hinges. The metasomatism of the pre-ore (753 Ma) and ore (698 Ma) stages took place under rifting conditions. Pre-ore quartz-muscovite and chlorite metasomatites with carbon mineralization and supra-background Au concentrations were formed under the action of reducing reaction solutions; they remained unaltered in the non-productive part of the deposit. These formations are characterized by elevated concentrations of radioactive elements and natural electrochemical polarizability. During the ore stage, Au was concentrated by ﬂuids with hydro-carbonate-sulﬁde composition under the violation of the strike-slip kinematics, which caused signiﬁcant petrophysical transformations of the productive part of the deposit. Early carbon metasomatites in the sub-ore and root sections of the ore bodies were depleted in terms of U, at the same time as retaining their electrochemical activity. Uranium accumulated in the upper horizons of the productive part, whose rocks lost their polarizability due to scattered carbonate mineralization. Magnetic pyrrhotite crystallized as part of sulﬁdes with a regular increase in its proportion in the root sections of the ore bodies. At the ﬁnal stage (368 Ma), the mineralized zone was broken into a series of blocks with unequal vertical displacements and levels of erosional truncation by upcasts. This led to the exposure of various-depth sections with contrast petrophysical characteristics.Conclusions. The Blagodatnoye deposit was formed in four stages: preparatory, two ore-generating and ﬁnal. The petrophysical features of the products of each stage formed the basis for the developed evolutionary petrophysical model, which will be tested on the materials of geophysical studies of the Yenisei Ridge territories.
