Optimizing the landslide-prone slope stabilization
Authors: Solsky Stanislav V. , Bykovskaya Sofya A. 
Published: November 2019

Introduction. Nowadays, the study of landslide processes is one of the most intensive aspects of construction and maintenance of industrial and civil buildings and installations. The landslides violate the stability of foundations and entire complexes of installations, so the assessment of the stability of the slopes is the most important task before starting the construction. Currently, there is a large number of landslide classifications, which characterize the conditions of their formation, the history of geological development, their age, and structure. Normative documentation gives three ways of slope slump control: preventive, restricting, and liquidation ones. However, this source does not give systematic validity of the engineering solutions. The study sets the following tasks: to develop an algorithm for the optimal choice of rational slope strengthening in landslide construction conditions and to test it with a specific example.
Materials and methods. The study analyzed the publications on theoretical and practical experience in dealing with landslides as well as normative documents. Numerical simulation methods were used to calculate the slope stability when testing the algorithm.
Results. Using the introduced classification, the study presented an algorithm that makes it possible to choose a rational way of slope strengthening under landslide construction conditions. The concept of the algorithm allows step-by-step approximating parameters of a landslide-prone slope model to the real conditions, on the one hand, and selecting the most reasonable anti-landslide measures, on the other hand. The developed algorithm was tested on the territory of a large industrial complex situated on river overflood plain fringes. By applying the value engineering comparison of several slope stabilization variants, the research has taken the most optimal one of them for realization.
Conclusions. The study developed the author’s classification and algorithm for the selection of optimal design solutions to stabilize landslide-prone slopes or slants. Successful approbation of the algorithm confirmed its practical applicability. The algorithm allows choosing the most effective complex for protection against landslides.
The influence of organizational and technological complexity on the period of job execution
Authors: Dorogan Igor A. 
Published: November 2019

Introduction. An essential index of the efficiency of the construction organization is its building period, which depends on the timing of individual work items. It is especially significant for large projects of public buildings including ones of medical establishments being complicated installations regarding their space-and-planning and technological aspects. It is known that the job duration is influenced by its complexity and number of workers assigned for it. However, the influence of the job complexity remains unexplored. It can be expressed by the average job grade and quantity of requirements for the job results. In addition to this, the nonlinear feature of the dependencies is not studied.
Materials and methods. A statistical study was conducted to examine the feature of the processes and the reason for managing requirements. It was based on the data of the job labor content, complexity and duration, the number of workers during the construction of the Research Institute of Pediatric Oncology and Hematology building of the Scientific Medicine Centre of Oncology named after N.N. Blokhin in Moscow. The analysis showed the regression equation, the correlation, and determination coefficients. The significance of the coefficients was estimated using the Student’s criterion.
Results. The study demonstrated a nonlinear dependence on the factors considered on the job duration. However, the average job grade is of a minor effect and can be excluded from the influencing factors. On the contrary, the quantity of requirements has a significant impact, which indicates the need to manage the requirements in the course of construction.
Conclusions. To reduce the job duration, it is necessary to create a requirements management system that will also improve the quality of the performed work. In the future, it is expedient to conduct research on other construction projects.

Abstract
The friction stir welding process is an innovative technique for joining metals using plasticity, without presenting the fusion. It was first applied to aluminum alloys, for example copper, steel alloys, polymers and others. In this work the effects of the rotational speed, the speed of travel and the axial force of the tool were grouped in a mathematical model to quantify their influences on the weld seam. In this context and with of the experimental tests, the desired objective through this study is to describe the tensile strength of the cord resulting from this welding operation, for the qualification of this type of parts with an optimum adapted to a given application.
The impact of changes in the geological conditions of road bedrock layers while the road was in use
Authors: Smugala Stanislav , Kubečková Darja , Indra František 
Published: November 2019

Abstract
This article examines the effective road reconstruction technologies applied during construction processes to ensure the required final quality of construction work. The construction quality and especially the overall levelness of roads are influenced by several factors. These factors include high-quality implementation of road structural layers, including active zones, which can be adversely affected by the undisciplined application of technology, insufficient engineering and poor geological surveys. Suitable and effective reconstruction technology provides the required quality of construction work yet does not significantly extend construction time. The authors propose stabilisation using cement or lime during reconstruction. This stabilisation method is used if the structure of the bedrock layers is finely granular. The stabilisation process consists of excavating the unacceptable bedrock layer and mixing it with additives and water. A principally different bedrock stabilisation method consists of completely replacing it with a gravel layer, which is used when individual base layers are diverse and stabilisation using additives would not guarantee the required results, i.e. improved strength characteristics. In some cases, the existing base layers are not suitable for use as road base layers because of their characteristics, such as volumetric instability. For this reason, they must be replaced with more suitable materials. This topic is documented by a practical example.

Published: November 2019

Abstract
Unlike energy efficiency, in terms of exergy efficiency it is possible to compare the existing operation of an energy conversion system with the ideal operation. Exergy loses and exergy destruction make it possible to identify the shortcomings of an existing system, which should be improved immediately. With exergy analysis, it is possible to identify the priority actions that need to be taken in order to improve the functioning of the system: greater exergy loss prevention is the highest priority. Energy efficiency refers to the useful work and investments needed to obtain useful work and investments needed to obtain energy efficiency; this is important to some extent, but the effectiveness of exergy makes it possible to compare system performance with the ideal. Results shows that the highest exergy destruction of a single-stage compressor refrigeration system from all working condition is found when ambient temperature and freezer temperature difference is 10 ºC, pressure in compressor is 0.62 MPa, ammonia temperature after compressor is 90 ºC, total exergy destruction of single-stage compressor refrigeration system 97.84 kW. The highest exergy efficiency of a single-stage compressor refrigeration system from all the working conditions is found when ambient temperature and freezer temperature difference is 39 ºC, pressure in compressor is 0.45 MPa, ammonia temperature after compressor is 128 ºC, exergy efficiency of a single-stage compressor refrigeration system is 59.76 %. The highest total exergy destruction of a two-stage compressor refrigeration system from among all the working conditions is found to be when the ambient temperature and freezer temperature difference is at 13 ºC, pressure in compressor 0.44 MPa, ammonia temperature after compressor 76 ºC, total exergy destruction 83.86 kW. The highest exergy efficiency of a two-stage compressor refrigeration system from among all the working conditions is found to be at an ambient temperature and freezer temperature difference of 39 ºC, pressure in compressor 0.56 MPa, ammonia temperature after compressor 92 ºC, exergy efficiency 53.55 %.

Published: November 2019

El presente artíulo presenta un análisis y síntesis sabre los procesos de aseguramiento de la calidad y acreditación realizados en Chile, como de algunos de sus principales resultados y desafios. La masificación de la educación superior, el surgimiento de universidades privadas, la presión de los contextos internacionales, el autofinanciamiento, y el giro en el rol del Estado Chileno, desde un enfoque subsidiario a uno contralor, condujo una transformación radical en el Ser y quehacer de la Universidad. En este contexto la sociedad civil exige rendición de cuenta, responsabilidad social y calidad entendida bajo las categorías UNESCO de pertinencia, relevancia, equidad, eficiencia y eficacia.
Con más de 30 años de transformaciones se vive un momento de inflexión que cuestiona el modelo y realidad de la Educación Superior en Chile.
Construcción de identidad y estructuras de poder y control en el aula de clase
Authors: López Jiménez Nelson Ernesto , Celeita Buitrago Laura Estefany , Perdomo Cortés Wilson Roberto 
Published: November 2019

Dando continuidad a la línea de trabajo investigativo, el Grupo PACA, Categoría A de Col­ciencias, se presenta un estudio sistemático sabre las relaciones de poder y control que subya­cen en el aula de clase y que a la postre contribuyen a la construcción de identidad profesio­nal o subjetividad de las estudiantes.
Los conceptos de poder y control, en la teoría de Bernstein y continuadores (Dias Villa, Lopez Jimenez, Ortega, Cox, Daniels, Morais ... ) aunque estan interrelacionados, son analíticamen­te diferentes y operan en niveles distintos. El poder crea límites, establece límites, legitima límites, reproduce límites entre categorías, sean estas agentes, agencias o discursos. El con­cepto de control, tarnbien establece limites pero ya no entre categorías, sino en el nivel de la comunicación. El control nos remite a la interacción, a las relaciones de poder de la interac­ción, a los límites de la interacción.
Se plantearon coma objetivos principales el estudio de las estructuras de poder y control que permean y determinan la relaciones en el salon de clase y, a su vez, el impacto que tienen dichas relaciones en la construcción de subjetividades o identidades profesionales.
Crear un espacio de lectura

La Asociación Colombiana de Universidades, comprometida con el mejora­miento de la calidad de la educación superior, considera el tema de la lecto- escritura como uno de los más urgentes y relevantes. En efecto en educación superior, la lectura y la escritura no se pueden separar de asuntos tan sensibles como la del abandono, el rendimiento académico, el fortalecimiento de la in­vestigación, la producción de conocimiento y el desarrollo de competencias laborales, entre otros, que representan, hoy por hoy, criterios básicos para los procesos de acreditación.
Las investigaciones recientes en este campo han mostrado que los diversos saberes requieren de diferentes prácticas lectoras y escritúrales, las cuales, a su vez, precisan de procesos formativos específicos. Así, se viene reconociendo cada vez más que tales procesos no son exitosos cuando, como ocurre tradi­cionalmente, sólo se los deja a cargo de los profesores de lengua y comunica­ción. Las dificultades que la universidad enfrenta en este terreno, no puede ser resultados sin una política que comprometa a todas las personas implicadas en el formación universitaria.
Personality profiling of flying instructor and trainee instructor
Authors: Anand K , Sharma V 
Published: November 2019

Introduction:
Military flying entails sound psychological health along with a high level of skill and aptitude. Pilots are selected on the basis of their psychological profile, psychomotor ability, and cognitive ability. Hence, the performance of pilots can be construed as a product of skill, attitude, and personality factors. Personality factors and cognitive ability have a vast impact on the flying performance and flight safety. This acquires a whole new dimension for flying instructors, as teaching the nuances of flying to a young flight cadet is a very challenging task.

Materials and Methods:
To study the personality and cognitive profile of the special group of flight instructors, 45 instructors and trainee instructors from flying instructors’ school, Tambaram, were administered NEO five- factor inventory and four cognitive tests comprising Stroop test, symbol-digit coding and digit span-backward and forward. The data were analyzed using descriptive statistics, t-test, and analysis of variance.

Results and Discussion:
Trainees and instructors constituted the sample wherein they were considered as a common group; hence, comparison between them was not carried out. The aircrew manifested emotional stability, high extraversion, willingness to experience novel experiences, low to average agreeableness, and average to very high conscientiousness. Their cognitive performance was compared with available norms for general population and was found to be above average. No significant difference was found in the personality dimensions or cognitive performance on the basis of mode of entry, stream, marital status, etc.

Conclusion:
Instructors came out to be more emotionally balanced, extraverted, and keen to have new experiences and had high conscientiousness compared to non-instructor pilots. The instructors showed above- average performance when compared to normative data provided by the test authors. It has implications for future studies with large samples and similar protocols.
Fragment Pose Prediction Using Non-Equilibrium Candidate Monte Carlo and Molecular Dynamics Simulations

Published: November 2019

Part of early stage drug discovery involves determining how molecules may bind to the target protein. Through understanding where and how molecules bind, chemists can begin to build ideas on how to design improvements to increase binding affinities. In this retrospective study, we compare how computational approaches like docking, molecular dynamics (MD) simulations, and a non-equilibrium candidate Monte Carlo (NCMC) based method (NCMC+MD) perform in predicting binding modes for a set of 12 fragment-like molecules which bind to soluble epoxide hydrolase. We evaluate each method's effectiveness in identifying the dominant binding mode and finding any additional binding modes (if any). Then, we compare our predicted binding modes to experimentally obtained X-ray crystal structures.We dock each of the 12 small molecules into the apo-protein crystal structure and then run simulations up to 1 microsecond each. Small and fragment-like molecules likely have smaller energy barriers separating different binding modes by virtue of relatively fewer and weaker interactions relative to drug-like molecules, and thus likely undergo more rapid binding mode transitions. We expect, thus, to see more rapid transitions betweeen binding modes in our study. Following this, we build Markov State Models (MSM) to define our stable ligand binding modes. We investigate if adequate sampling of ligand binding modes and transitions between them can occur at the microsecond timescale using traditional MD or a hybrid NCMC+MD simulation approach. Our findings suggest that even with small fragment-like molecules, we fail to sample all the crystallographic binding modes using microsecond MD simulations, but using NCMC+MD we have better success in sampling the crystal structure while obtaining the correct populations.
