La presente investigación muestra la influencia de la crisis provocada por el Covid-19 en los hábitos de consumo de estudiantes universitarios arequipeños, con el objetivo de conocer de qué manera y qué elementos de los hábitos de consumo se vieron influenciados, y cómo variaron antes y durante la pandemia y las perspectivas para el futuro. Para hacer este estudio se tomaron en cuenta antecedentes de otras investigaciones de la crisis por Covid-19 realizadas en diferentes países y distintos grupos etarios. Luego, se recogieron datos de una muestra de 382 universitarios y se analizaron de manera descriptiva los cambios en las necesidades del consumidor, la actitud de consumo, el lugar de compra y las distintas categorías de productos y servicios que se vieron influenciadas por esta crisis. El estudio encontró que, a partir de la pandemia, los universitarios arequipeños realizaron compras más racionales, se preocuparon por la búsqueda de información para la toma de decisiones de compra, y priorizaron la salud por encima de la necesidad social y de autoestima. Algunos hábitos adquiridos en la pandemia permanecerán, como las compras online y la educación virtual.
Natural energy resources and their impact on environmental pollution in the transport sector in Perú
Authors: Velásquez Chacón Erika , Molina Pinto Efraín Jesús
Published: February 2022

Natural energy resources such as natural gas are important in the development of countries that have reserves. These resources may also important in the reduction of polluting emissions generated by the vehicles of the automotive fleet. In this context, the production of natural gas fuel for vehicles allows the reduction of emissions and, consequently, of the levels of air pollution. The objective of this study is to evaluate natural energy resources and their impact on environmental pollution in the transport sector, the availability of these energy resources, the impact of pollution and the strategies for the reduction of emissions, in the Peruvian context, by reviewing information from various sources. Peru has developed projects for the production of natural gas and initiatives to distribute through a gas pipeline network. The growth of the vehicle fleet has generated high levels of air pollution in the country’s cities. Natural gas vehicle fuel emits almost no heavy particles, and does not generate much PM10, and as many polluting emissions such as CO2, CO, NOx, SO2, HC, generated by other fuels. There are still limitations in emission reduction strategies because the adaptation of vehicles to natural gas has decreased due to the high costs of the service and the perception of not obtaining benefits in its use, in addition to having few establishments that sell natural gas throughout the country.

Background. A vesicovaginal fistula (FVV) is a direct pathological connection between the bladder and vagina resulting in uncontrolled leakage of urine into the vagina from the bladder. Based on the cause, fistulas are divided into two, namely obstetric fistula and gynecological fistula. The risk factors that influence the occurrence of FFV consist of obstetric risk factors (age, parity, delivery method, duration of delivery, birth weight) and gynecological risk factors (history of gynecological surgery, history of pelvic radiotherapy, history of gynecologic malignancy). The purpose of this study was to determine the relationship between risk factors and the incidence of vesicovaginal fistula.

Methods. This research is an observational-analytic study with a cross-sectional method. The number of samples obtained was 74 patients who met the inclusion criteria using secondary data from medical records. Analysis of the data used is the chi-square test.

Results. There were 37 people who experienced vesicovaginal fistula. Where there were 9 patients with obstetric vesicovaginal fistula (24.3%) and 28 people (75.7%). From the Chi-Square test analysis, there was a significant relationship between delivery method (p=0.029), birth weight (p=0.029), history of gynecological surgery (p=0.038), history of pelvic radiotherapy (p=0.016), history of gynecological malignancy (p=0.016). =0.010). Meanwhile, there was no significant relationship between age (p=0,347), parity (p=1,000), and duration of labor (p=0,082).

Introduction: hydatid cysts are produced by the Echinococcus granulosus parasite. The single location in the muscles is rare. The cystic mass can be confirmed by ultrasound or magnetic resonance imaging (MRI) and its differential diagnosis may be difficult. Material and method: We present a case with a tumorous mass in thigh with MRI report: "encapsulated cystic lesion dependent on the biceps femoris, which contacts the sciatic neurovascular bundle, being the 1st diagnostic possibility hydatid cyst". Mebendazole was prescribed and after a month the tumor was excised, which was not located within the muscle but rather pushing it, attached to the sciatic nerve. Diagnosis after anatomopathological study was sciatic schwannoma. Discussion and conclusion: on MRI, schwannomas are usually seen as a mass adhered and eccentric to a nerve, but they can present cystic degeneration mimicking hydatidic cyst; Faced with a single muscular or perimuscular cystic tumor, close to the neurovascular bundle, with negative systemic tests for parasite disease, the schwannoma should be taken into account in the differential diagnosis.

Messkampagne: Staubminderung beim Kaltfräsen von Straßenbelägen/Measurement campaign: Reducing the level of dust produced during pavement milling
Authors: Süsselbeck Kai
Published: February 2022

Beim Kaltfräsen können die im Straßenbaumaterial verwendeten Gesteine zerkleinert werden, wodurch alveolengängiger und einatembarer Staub (A- und E-Staub), alveolengängiger Quarzstaub und – wenn mineralische Rohstoffe mit natürlichem Asbestgehalt verwendet wurden – Asbestfasern freigesetzt werden. Messwerte aus den letzten Jahren zeigen, dass die Bediener und das Bodenpersonal von Standard-Fräsmaschinen Expositionen ausgesetzt sein können, die über den Beurteilungsmaßstäben und ERB-Werten (ERB: Exposition-Risiko-Beziehungen) liegen [1]. Das Institut für Gefahrstoff-Forschung der Berufsgenossenschaft Rohstoffe und chemische Industrie (BG RCI) hat daraufhin in Zusammenarbeit mit der Fa. BOMAG eine neu entwickelte Staubminderungstechnik auf deren Wirksamkeit zur Reduzierung der Arbeitsplatzkonzentrationen in der Praxis auf verschiedenen Baustellen im In- und Ausland messtechnisch überprüft. Im Ergebnis ist eine Minderung der staubförmigen Emissionen beim Kaltfräsen von Asphalt durch den zusätzlichen Einsatz eines Elektroabscheiders möglich.

Planet Four: Derived South Polar Martian Winds Interpreted Using Mesoscale Modeling
Authors: Portyankina Ganna , Michaels Timothy I. , Aye Klaus-Michael , Schwamb Megan E. , Hansen Candice J. , Lintott Chris J.
Published: February 2022

For the first time, model-derived and imagery-derived wind directions and speeds have been compared in Mars’s south polar region. Seasonal fan-shaped deposits are routinely observed by HiRISE in the polar regions. They are widely accepted to result from CO2 gas jet eruptions. Fan lengths, sizes, and shapes can provide information about wind directions and strengths at the times such eruptions occur. We utilize a catalog of those fan-shaped deposits, marked by citizen scientists within the framework of the Planet Four (P4) project, at 27 regions of interest (ROIs) for two spring seasons (Mars years 29 and 30). Fans change considerably from one HiRISE image to another at most of these ROIs as wind direction changes over the spring season. Leveraging this characteristic, intraseasonal variations in near-surface wind speeds and directions were retrieved and compared to near-surface winds predicted by a mesoscale atmospheric model (MRAMS) at the same ROIs. At most ROIs P4-inferred wind directions are consistent with those from MRAMS. The P4-derived wind speeds are less constrained but are consistent with MRAMS wind speeds at the majority of ROIs. The overall consistency between the P4-inferred and MRAMS wind directions supports the underlying assumption that fan formation is controlled by the wind and is not simply due to ballistic trajectories of material exiting suitably nonvertical vents. Measurements of seasonal fan-shaped deposits in HiRISE imagery can thus provide important intraseasonal information about near-surface winds—invaluable for both validating climate modeling and quantitatively investigating Mars’s polar processes.
An Energy Balance Model for Rapidly and Synchronously Rotating Terrestrial Planets
Authors: Haqq-Misra Jacob , Hayworth Benjamin P. C.
Published: February 2022

This paper describes the habitable energy balance model for exoplanet observations (HEXTOR), which is a model for calculating latitudinal temperature profiles on Earth and other rapidly rotating planets. HEXTOR includes a lookup table method for calculating the outgoing infrared radiative flux and the planetary albedo, which provides improvements over other approaches to parameterizing radiative transfer in an energy balance model (EBM). Validation cases are presented for present-day Earth and other Earth-sized planets with aquaplanet and land planet conditions from 0° to 45° obliquity. A tidally locked coordinate system is also implemented in the EBM, which enables calculation of the horizontal temperature profile for planets in synchronous rotation around low-mass stars. This coordinate-transformed model is applied to cases for TRAPPIST-1e as defined by the TRAPPIST Habitable Atmosphere Intercomparison protocol, which demonstrates better agreement with general circulation models than with the latitudinal EBM. Advances in applying EBMs to exoplanets can be made by using general circulation models as a benchmark for tuning as well as by conducting intercomparisons between EBMs with different physical parameterizations.
Duration of Tumor-infiltrating Lymphocytes Assessment with Significant Overall Survival Prognostic Value in Locally Advanced Breast Cancer
Authors: Sudarsa I Wayan , Aryanti Citra
Published: February 2022

Background Tumor microenvironment, represented by tumor-infiltrating lymphocytes, was dynamically evolving throughout the time. Thus, in the interpretation of TIL as a prognostic factor overall survival of breast cancer, it is important to note the duration of the TIL examination until neoadjuvant chemotherapy is performed.
Aim To determine whether the assessment of TIL at a certain duration still has value as a prognostic factor for the overall survival of breast cancer and its cut off point.
Methods This was a retrospective cohort study that included subjects with locally advanced breast cancer in Sanglah General Hospital, registered in Bali’s Cancer Registry. The study has been approved by the institutional review board of Udayana University, Denpasar, Bali. Data collected were age, breast cancer subtype, value of TIL, time of NAC start, and duration of survival. Missing data were obtained from electronic medical records. TIL is then grouped into groups with low TIL (negative and +1) and high TIL (+2 and +3). Data analysis were done with Statistical Package for the Social Sciences 25.0.
Results As many as 150 subjects with locally advanced breast cancer who survived and died in 2011-2020 were analyzed. The mean age of subjects in this study was 48.7 (SD 9.3) years with a median survival of 47 months. The mean duration of the TIL asessment to NAC was 46.3 days (SD 24.5). The duration cut off point of TIL assessment to NAC that is valuable as breast cancer’s overall prognostic value was 31 days (AUC 0.716, Sensitivity 64.1%, Specificity 35.5%). In subjects with TIL examined for less than 31 days, it was found that TIL could significantly prognosticated the overall survival of breast cancer (p = 0.005). High TIL was associated with better overall survival and low TIL is associated with poor overall survival.
Discussion Tumor immune microenvironment played an important role in tumor progression and supression.  High levels of TIL has been generally accepted as an indicator for a more robust anti-tumor immune response, thus yielding favorable outcome. Timing of TIL analysis was important to determine as microenvironment dynamically progressing. In this study, we proved that timing matters and only short-term duration of TIL assessment to NAC meaningful as a prognostic value for breast cancer’s overall survival.
Conclusion The duration of TIL to NAC assessment was important in determine the meaningful of TIL value in the prognostication overall survival of locally advanced breast cancer. The short-term TIL assessment duration (<31 days) predicted well, but not in the long term assessment duration. In the future, it is hoped that clinicians will be more critical in the interpretation of TIL, especially the duration of TIL assessment before NAC.

Published: February 2022

Background
Resident supervision plays an important role in accomplishing service excellence in teaching hospitals, while still supporting residents’ competency achievement. This preliminary study aims to obtain an overview of resident supervision and the achievement of quality services to conduct hospital accreditation standard.
 
Material and methods
A retrospective study with a cross-sectional design was conducted in May 2020 involving Obstetrics and Gynecology residents who carried out a Caesarean section.  Data was collected from medical records manually, with additional information from Obstetrics and Gynaecology Department. Univariate analysis was completed to generate a profile of supervision and the achievement of quality services in accordance with  hospital accreditation standard.
 
Result
Of the 86 Caesarean sections conducted in May 2020, only 75 involved residents, with 42 (56%) procedures carried out by chief residents and 33 (44%) by apprentice stage residents. Supervision during procedures was carried out in 74 cases (98.6%), with 33.3% given moderate-high supervision during hospitalization, 52% moderate low, and 14.7% low supervision. The completeness of the medical records revealed 85,3%  appropriate marked site, 96% surgery reports, 78,7% education sheet.  It is found that  64 % of pre-operative visits and  65,3% of post-operative visits were carried out by residents. In addition, case discussion, death case reports,  as well as  resident evaluation were carried out to conduct patient safety and quality service improvement.
 
 
 
Conclusion
Supervisory evaluation could be provided directly or by conducting case discussions, as well as medical record review; otherwise, to enhance quality achievement, the development of an integrated supervision system is required.

Mantis lacewings (Neuroptera: Mantispidae) are prominent and charismatic predatory representatives of Insecta. Nevertheless, representatives of the group are surprisingly scarce in Paleogene deposits after a relative abundance of specimens known from Cretaceous. Here we present Mantispa? damzenogedanica sp. nov., representing the first adult of Mantispidae described from Baltic amber and the only Eocene adult mantispid hitherto preserved in amber. The new fossil species is also among the earliest representatives of Mantispinae, certainly the oldest adult of this group described from amber. Additionally, we discuss the changes through time in the ecological morphospace within Mantispidae based on the morphological diversity (≈disparity) of the raptorial legs. Possible explanations for the post-Cretaceous decline in the morphological diversity of mantis lacewings are posited.

2021 Korean Heart Rhythm Society Guidelines for Catheter or Surgical Ablation of Atrial Fibrillation
Authors: Lim Woo-Hyun , Shim Jaemin , Lee Ji-Hyun , Joung Boyoung
Published: February 2022

Rhythm control therapy is used in atrial fibrillation (AF) management to improve AF-related symptoms along with rate control. AF catheter ablation is effective in maintaining sinus rhythm and has an acceptable complication rate. Compared with antiarrhythmic drugs, AF catheter ablation is superior with respect to arrhythmia-free survival and improvement in the quality of life. Therefore, AF ablation is recommended for rhythm control after the failure of antiarrhythmic drugs and is sometimes considered a first-line therapy for AF patients. Radiofrequency and cryoballoon ablation show similar efficacy, with slightly different complication profiles. Surgery for AF is also an effective rhythm control therapy and should be considered in patients undergoing cardiac surgery or in those with failed catheter ablation. For patients undergoing AF catheter ablation, performing ablation under uninterrupted warfarin or non-vitamin K oral anticoagulant treatment is recommended for periprocedural stroke risk management. Here, we review existing data and discuss the general principles of AF catheter and surgical ablation in patients with AF.
Healthy Nursing Academic Work Environments
Authors: Brady Marilyn
Published: February 2022

Healthy work environments in the nursing academic setting are essential for the recruitment and retention of faculty; they also serve to promote excellence in nursing education. Although the early efforts addressing healthy work environments focused on the clinical practice setting, more recent efforts have also considered the work environment in academic settings. The National League for Nursing has focused on work environments in academia and has published the Healthful Work Environment Tool Kit© that can be used by applicants for faculty positions, current faculty members, and nurse administrators to assess an academic work environment. The tool kit addresses the following nine work-related areas: salaries, benefits, workload, collegial environment, role preparation and professional development, scholarship, institutional support, marketing and recognition, and leadership. These areas are used to frame the discussion of how nursing faculty and administrators can work together to assess and enhance the health of nursing academic workplaces.

Points de vue sur la jeunesse – Volume 1
Authors: Antonucci Lorenza
Published: February 2022

Le développement considérable de l’enseignement supérieur est l’un des changements les plus importants qu’aient connu les sociétés européennes et les jeunes ces quarante dernières années. Cette évolution s’est faite dans l’objectif non seulement de garantir l’égalité des chances, mais également de créer une économie de la connaissance compétitive pour faire face à la concurrence sur le marché mondial. Cette rhétorique à double objectif est désormais de plus en plus problématique, compte tenu du taux de chômage en hausse chez les jeunes diplômés (Bell et Blanchflower, 2010). En outre, les mesures d’austérité appliquées dans toute l’Europe exercent une pression sur les systèmes d’aide aux jeunes qui se lancent dans des études supérieures. L’article propose une vue d’ensemble des tendances actuelles de l’aide aux étudiants en Europe, en procédant à une analyse politique de documents officiels, aux niveaux national et européen. L’analyse des changements intervenus au niveau des politiques distingue : les instruments des politiques d’aide aux étudiants (par exemple les bourses et le recours de plus en plus important aux prêts), les degrés d’universalisme et la mise en place des conditions de ressources (par exemple la sélection de plus en plus stricte pour l’octroi d’une aide aux étudiants). Selon l’article, la participation massive à l’enseignement supérieur n’aura pas baissé en 2020. L’auteur indique également que l’incidence des mesures d’austérité sur l’aide aux étudiants se traduira par une expérience différenciée de l’enseignement supérieur, car de plus en plus d’étudiants devront payer eux-mêmes leurs études supérieures, notamment en participant au marché du travail et en se faisant aider par leur famille. Enfin, l’article passe en revue des éléments qui pourraient inverser les tendances actuelles, et met l’accent sur les processus d’intégration et d’européanisation de l’enseignement supérieur qui ont récemment abouti à la création de l’Espace européen de l’enseignement supérieur (EEES).
Points de vue sur la jeunesse – Volume 4
Authors: Rhanem Karima
Published: February 2022

Au lendemain du Printemps arabe, au Maroc, au Moyen-Orient et dans la région de l’Afrique du Nord, un certain nombre d’organisations dirigées par des jeunes ont utilisé les médias sociaux comme moyen de mobilisation, d’échange et de promotion de la participation civique et des valeurs démocratiques. Parmi ces organisations, plusieurs ont mené des campagnes de revendication visant à lancer le débat public autour de questions socioéconomiques et politiques urgentes, à défendre ou à contester certains points ainsi qu’à proposer des changements s’agissant de la législation et des politiques publiques. Il est certain que l’utilisation des médias sociaux est devenue pour la jeunesse un moyen important de promouvoir le changement dans leurs communautés et d’assurer une participation transparente et démocratique à la prise de décisions. Le chapitre met en exergue des exemples concrets d’initiatives qui constituent de bonnes pratiques.
Points de vue sur la jeunesse – Volume 4

Tantôt dénommés « génération Google » (Rowlands et al ., 2008), « Net Geners » (génération internet) (Tapscott, 1991) ou « natifs du numérique » (Prenksy, 2001), les jeunes d’aujourd’hui ont grandi dans un monde dominé par internet, avec de nouvelles opportunités de participation et d’engagement. Dans l’ensemble, le discours de la recherche a souvent affirmé que les jeunes sont naturellement doués d’aptitudes numériques. Comme certains faits le montrent pourtant, il existerait un écart entre la perception qu’ont les jeunes de leurs aptitudes numériques et leur capacité à naviguer dans cet univers complexe de manière sûre et constructive (Christofides et al ., 2009). La politique d’internet appliquant généralement une approche générique vis-à-vis des « utilisateurs » (c’est-à-dire les adultes), les droits des enfants et des jeunes s’en trouvent souvent négligés (Livingstone et al. , 2016). De plus, d’aucuns ont prétendu que le fait de se polariser sur le discours des natifs du numérique occulte la nécessité d’aider les jeunes à améliorer leurs aptitudes numériques (Fondation ECDL, 2014 ; Livingstone, 2011). Résultat : les programmes éducatifs font souvent l’impasse sur des compétences essentielles. La fracture initiale de l’accès physique à internet s’est transformée en fracture au niveau des compétences (Van Deursen et Van Dijk, 2011). Remédier à cette fracture permettra de multiplier les possibilités pour les jeunes de participer de manière constructive au monde numérique. Il faut leur apporter des compétences supplémentaires pour leur permettre de répondre à leurs besoins d’information, mais aussi pour qu’ils comprennent mieux les normes de l’environnement en ligne. En matière de technologie, l’éducation est souvent associée à des compétences de niveau fonctionnel – utilisation de progiciels, navigation, recherche de compétences, capacité à discerner la qualité des informations trouvées en ligne. Or, pour la culture numérique, l’éducation doit couvrir une série de compétences plus large reflétant l’engagement social et culturel des jeunes dans une société fonctionnant en réseau, leur manière de s’exprimer, leur formation identitaire et leur participation au monde en ligne. Ce chapitre explore la culture numérique des jeunes dans le contexte européen, en cherchant à savoir où et en quoi les compétences numériques favorisent l’inclusion, l’engagement et la participation des jeunes au monde numérique. La recherche s’appuie sur des exemples de dispositifs utilisés par l’éducation, tant formelle qu’informelle, dans le domaine du numérique. Le cas de l’Irlande est décrit à titre d’illustration. Les questions concernant la participation des jeunes à un monde numérique sont considérées dans le cadre d’une culture numérique, ce qui contribue au développement théorique, à l’enrichissement des connaissances ainsi qu’à éclairer sur les politiques et sur les recommandations de bonnes pratiques.
Research of the Brittleness and Crack Resistance of Samples Made of Highly Hardened Silicon Carbide Ceramics
Authors: Dushko Oleg , Voronkova Galina , Rekunov Sergey
Published: February 2022

The paper presents a quantitative assessment of the brittleness of highly hardened silicon carbide ceramics. This characteristic is important for predicting the strength characteristics of the material. The analysis of existing methods for determining the brittleness of the material is carried out. During the research, it was assumed that the production of composite materials in the SiC-Al2O3 and SiC-Al2O3-AlN systems would combine high chemical resistance, wear resistance, and low coefficient of friction. These properties inherent in aluminum oxide and nitride, along with high thermal conductivity and strength, are characteristic of silicon carbide. Materials in the SiC-Al2O3 system containing 20, 50 and 80 percent of aluminum oxide – Al2O3 were selected as objects of research. Their advantages and disadvantages are shown. The results of an experimental study of samples made of highly hardened silicon carbide ceramics are presented. Based on experimental studies, analytical and graphical dependences are proposed that allow determining the crack resistance of ceramics from the crack length at the corners of the Vickers pyramid. It is shown that these dependences change exponentially, which makes it possible to predict the appearance of cracks at various stages of mechanical processing of products made of highly hardened ceramic materials.
Protection against Atmospheric Corrosion by Means of Coatings Based on a Fluorine-Containing Surfactant
Authors: Gaidar S. , Karelina M.Yu. , Quang H.
Published: February 2022

The paper presents approaches to solving the problem of protecting equipment against corrosion, aging and damage due to biological reasons, which is one of the most urgent practical problems. The practical significance of this problem is relevant when using machinery both for its intended purpose and during storage. As one of the research areas, the urgency of the problem determines the testing of new technologies and conservation materials developed on a fluorine-containing surfactant. Due to the fact that the preservation of equipment during long-term storage implies its being in a mothballed state for long periods of time - up to 12-15 years, it is rather inefficient to carry out full field tests due to a significant amount of time spent on the introduction of new technologies and their significant obsolescence during tests. Therefore, accelerated laboratory and climatic tests in accordance with standards and GOSTs were selected as the main test methods.
Stress-Strain State Multistory Buildings and Stiffness Shear Bonds
Authors: Lyublinskiy Valery
Published: February 2022

The paper considers issues the nonlinear behavior of shear bonds affecting the changes in the distribution of stresses and strains in vertical structures, as well as to compare these stresses and strains with the linear statement of the problem solution in which the compliance of the bonds is constant. In a complex multiconnected system of the multistory building, the new redistribution of stresses arises, which does not coincide with the original distribution of stresses. To correct the stiffness value for the bonds, the experimental data of MGSU were used. A secant module was used to determine the stiffness for links such as lintels. Loading was performed by the step method. Redistribution of stresses in the load-bearing elements of the building showed their significant leveling. The issue of ultimate deformations of shear bonds limiting the process of redistribution of stresses and deformations requires discussion.
The Problem of Asbestos-Cement Sheets Disposal in the Kłobuck Poviat
Authors: Brycht Natalia , Ulewicz Malgorzata
Published: February 2022

Asbestos-cement products (eternit) were a commonly used roofing material for residential and farm buildings. Due to the harmfulness of this product, in 1997 its production and use was banned in Poland. In 2002 the Polish government adopted a program aimed at the complete removal of these materials from buildings by 2032. Despite the possibility of obtaining funding for the removal of asbestos, the process is slow. Inhabitants of small communes often dismantle asbestos products in an inappropriate way on their own, which has a negative impact on the environment and poses a threat to human health. The article presents the results of the CAWI (Computer Assisted Web Interview) survey, identifying the methods of developing asbestos roofing over the last twenty-four years in five selected towns of the Kłobuck poviat. An „in situ” visual assessment of the identification of products in these localities was performed and indicators showing changes in the manner of their management were estimated. Moreover, the respondents also specified the future intention to neutralize the asbestos panels still on the buildings. It was found that in the analysed period, there was an increase in disassembly works carried out by companies specialised in the disposal of asbestos cement to the level of 72%, with a simultaneous decrease in the share of negative practices by 65%. Unfortunately, over 55% of farm buildings in the analysed area are still covered with eternit. Low environmental awareness and high costs of changing the roof covering make it impossible to solve this problem quickly.
Methodology for Assessing the Technical Condition of Buildings and Structures Using the Reliability Criterion
Authors: Dekhterev Denis , Tamrazyan Ashot
Published: February 2022

As a result of the design and construction of buildings and structures, the level of reliability of the construction structure or construction object as a whole is formed. The reliability specified in the project does not remain constant, but changes over time as a result of the imperfection of the design model of the building, inaccuracies of installation, as well as during the accumulation of defects and damage to the building during its use. Currently, the scope of work related to the assessment of the technical condition of buildings is constantly increasing. This is due not only to the increasing number of operated structures, but also an increase in safety requirements and an increase in the qualitative characteristics of buildings. The article proposes to maintain a unified approach to the inspection of the engineering and technical condition that uses the reliability criterion for the basic structural elements of buildings and structures. In modern conditions, it is important to determine the necessary level of reliability acceptable to economic considerations and meets modern safety requirements. It is important to calculate the numerical threshold values of the categories of the technical condition of building structures to eliminate the subjective approach to the assessment of their technical condition.
Thin SiC and Gan-Based Films and Structures: Production and Properties
Authors: Sankin A.V. , Altukhov V.I. , Dadasheva Z.I.
Published: February 2022

The article describes the methods for producing thin films and structures based on SiC, GaN and their SiC – AlN and Al – GaN solid solutions, as well as mathematical models of film growth and properties-behavior of the I–V characteristics of heterostructures. Two models were developed for producing thin films and heterostructures based on SiC, GaN and their solid solutions. The first model makes it possible to determine the sputtering coefficient when producing films by high-frequency magnetron sputtering. In the second quantum-mechanical model, the equation for the gap of the mean field of condensate was built and the growth rate of a film on the crystalline substrate was determined. The current-voltage characteristic of the transistor based on the AlGaN / GaN heterosystem was provided. The models for the growth of heterostructure films made it possible to modify the technologies for producing perfect SiC crystals and SiC – AlN solid solutions. It was possible to offer a pilot plant for growing SiC crystals with improved control over the modes of induction high-temperature heating of the growth crucible.
