Рассматривается методика и результаты расчета диффузионных процессов в дымовых трубах теплогенерирующих установок. Методика состоит из шести этапов, включающих моделирование газодинамических и тепломассообменных процессов на основе дифференциальных уравнений движения, неразрывности потока, сохранения энергии.Дифференциальные уравнения движения записаны для турбулентного режима. Для расчета параметров влагообмена в стенке трубы использовалась интегральная форма уравнения диффузии. Течение с теплообменом моделировалось в программном комплексе Flow Vision. Для расчета диффузионных процессов в стенке трубы использовалась разработанная авторами компьютерная программа.С целью апробации методики произведены расчеты диффузионных процессов в железобетонной сборной дымовой трубы высотой30 ми диаметром 1,2 м при параметрах наиболее холодного месяца. В результате расчетов выяснено, что зоны возможной конденсации располагаются в наружных слоях стенки трубы или на ее наружной поверхности. Отмечено значительное влияние скорости течения дымовых газов в трубе на температурно-влажностный режим стенок.Отличие методики от известных методик заключается в учете факторов, значительно влияющих на температурно-влажностный режим дымовых труб: размерных особенностей дымовых труб, нестационарности процессов, теплофизических и газодинамических характеристик удаляемых газов, состава природного газа. Методика на этапе проектирования дает возможность спрогнозировать диффузионные процессы в дымовых трубах теплогенерирующих установок, а также определить режимы эксплуатации действующих установок.

El sistema de salud como instrumento de justicia social. Curso Optativo en la Facultad de Ciencias Médicas – UNLP. Caso Expósito
Authors: Costanzo Fernanda Arrondo 
Published: October 2019

Este trabajo tuvo por objeto el diseño de un curso optativo para proponer su inclusión en la Facultad de Ciencias Médicas de la Universidad de La Plata (en adelante FCM.UNLP), y así fortalecer el tratamiento curricular de los problemas de salud pública relacionados con la equidad, calidad, humanización y seguridad en salud.
El mismo, y a través del análisis de un material en formato audiovisual denominado “El caso Expósito”, propone reflexionar sobre ciertas tradiciones de la práctica profesional que se reproducen a través de las generaciones e incorporar en los futuros egresados conocimientos específicos, a fin de contribuir a incrementar la masa crítica de profesionales sensibilizados y capacitados en este problema prioritario de salud pública.
Este cambio de paradigma, que pone en tensión al llamado modelo médico hegemónico, debe ir acompañado de una ruptura metodológica, que repiense el vínculo docente-alumno-contenido. Es por ello que se propone desarrollar en el aula, a través de las relaciones entre alumnos y con los docentes, los valores, principios y formas de pensamiento necesarios para el abordaje de este tipo de problemas en la práctica profesional: trabajo en equipo, colaborativo, interdisciplinario, horizontal y predispuesto a la autocrítica.

Modified Newton method to determine multiple zeros of nonlinear equations
Authors: Thukral Rajinder 
Published: October 2019

New one-point iterative method for solving nonlinear equations is constructed. It is proved that the new method has the convergence order of three. Per iteration the new method requires two evaluations of the function. Kung and Traub conjectured that the multipoint iteration methods, without memory based on n evaluations, could achieve maximum convergence order2n-1 but, the new method produces convergence order of three, which is better than expected maximum convergence order of two. Hence, we demonstrate that the conjecture fails for a particular set of nonlinear equations. Numerical comparisons are included to demonstrate exceptional convergence speed of the proposed method using only a few function evaluations.

Authors: Zaka Orgest 
Published: October 2019

In this paper, based on several meanings and statements discussed in the literature, we intend constuction a affine plane about a of whatsoever corps (K,+,*). His points conceive as ordered pairs (Î±,Î²), where Î± and Î² are elements of corps (K,+,*). Whereas straight-line in corps, the conceptualize by equations of the type x*a+y*b=c, where aâ‰ 0K or bâ‰ 0K thevariables and coefficients are elements of that corps. To achieve this construction we prove some theorems which show that the incidence structure A=(P, L, I) connected to the corps K satisfies axioms A1, A2, A3 definition of affine plane. In all proofs rely on the sense of thecorps as his ring and properties derived from that definition.

Published: October 2019

Abstract
Main objective of the study is to analyse the impact of portfolio management on the level of quality in EU projects implemented in public universities. First part of the article is theoretical and prepared on the basis of a critical analysis of literature in the field of quality management in projects and project portfolios. Second part of the text was based on primary data collected during preliminary survey conducted among EU project managers implemented in public technical colleges in the 2014-2020 financial perspective. Literature studies and results of own research allowed to identify and assess threats affecting the quality level in EU projects that result from transition from the level of individual project management to the level of project portfolio management. Continuous improvement of quality is a characteristic feature of organizations using quality management systems, so the article indicates the need to have an internal quality assurance system at universities. Importance of organizational units managing EU projects in universities in ensuring that products and results of a project are of high quality have also been underlined.
Access to Data and Employee Actions for Information Security
Authors: Justyna Żywiołek , di Taranto Alberto 
Published: October 2019

Abstract
Access to data is a nefralgic information security zone. On the one hand, we do everything to protect them against disclosure, and on the other hand, we need a new employee to provide data and information to be able to do their job.
Managing access to data in the enterprise significantly affects the level of security in all areas of activity. The article presents the results of research in the field of security of policy objectives in a selected production company. The purpose of preliminary research is to analyze selected issues in the field of data access, control methods and employee responsibility.
The article discusses the results of research on the access to information by employees. Lack of access to the data paralyzes their work, but their excess causes information chaos and makes it difficult to make a decision. The research results clearly indicate that access to data is treated as a priority, forgetting about access to computer software, mobile devices, which can also be the security of the company.
Risky Energy Aspects – Identification, Evaluation, Acceptability Assessment and Improvement Aims
Authors: Karkoszka Tatiana 
Published: October 2019

Abstract
The increasing worldwide energy consumption, especially in the industry range, forces the companies to search for the solutions, which – being written into sustainable development philosophy – would allow for reducing the level of the energy consumption of the realised processes and lowering the costs of their functioning. Those activities can be undertaken in the systemic way, very often based on the implementation of the energy management system, they can also have the character of technical or technological modernisation. Fundament of the decision concerning the manner of the minimisation of energy consumption should always be the energy risk management covering: its identification, evaluation and acceptability assessment. The studies proposed the principles for defining the significant energy aspects by the full identification of all the present aspects and next the development of unified methodology of their assessment, allowing for appointing the key aspects. The starting point constitutes the energy risk ratio, which takes into consideration the following criteria: probability of the occurrence, significance of the occurrence, ability to monitor, incompatibility with legal requirements, and the interest and attention of the stakeholders. Flexibility of the applied method enables complex application in every organisation – independently of its size and sort of the realised processes – which wants to manage the risky energy aspects.
Analysis of the Possibility of Parallel Implementation of the Quality Management System and of the Corporate Social Responsibility System into a New Organization
Authors: Hofbruckerová Zdenka , Václavík Martin 
Published: October 2019

Abstract
Corporate Social Responsibility (CSR) concept is focused on understanding and managing the impacts a company has on the world around it and doing so as a part of core business activities. The common practice of most organizations is to implement a quality management system (mostly according to ISO 9001), and then implement other management systems. Companies in the Czech Republic have the possibility of certification of CSR via the Czech standard CSN 01 0391: 2013 which corresponds to the structure and requirements of other ISO standards. The article analyses common elements of both standards. The output is a proposal of the process of parallel implementation of these two management systems into a newly established organization.

Published: October 2019

Abstract
Calculation of the thermal dynamic properties of the multi-layer wall isolation of residential buildings is presented in this paper. Taking into account that the final objective is to create a building with the highest energy efficiency ratio, i.e. with the lowest energy consumption, both for heating and cooling, it is necessary to realize the good thermal characteristics of the multi-layer wall. To obtain the optimal solution for the wall's structure, various wall structures with different thicknesses of the individual layers, were analyzed. Based on results, presented in this paper, one can conclude that for walls with the same total thickness, but various thicknesses of the individual layers, that constitute the complete wall structure, the differences appear in the delay of the change of the walls outside temperature. In that way, by varying those individual layers' thicknesses, one can obtain the optimal solution for the wall structure with the highest savings of energy.
Weight Minimization of Spatial Trusses with Genetic Algorithm
Authors: Grzywiński Maksym , Selejdak Jacek 
Published: October 2019

Abstract
A genetic algorithm is proposed to solve the weight minimization problem of spatial truss structures considering size and shape design variables. A very recently developed metaheuristic method called JAYA algorithm (JA) is implemented in this study for optimization of truss structures. The main feature of JA is that it does not require setting algorithm specific parameters. The algorithm has a very simple formulation where the basic idea is to approach the best solution and escape from the worst solution. Analyses of structures are performed by a finite element code in MATLAB. The effectiveness of JA algorithm is demonstrated through benchmark spatial truss 39-bar, and compare with results in references.

Authors: Zatkalíková Viera , Markovičová Lenka , Hanusová Patrícia 
Published: October 2019

Abstract
AISI 304 austenitic stainless steel is recommended and used for various applications in industry, architecture and medicine. Presence of halides in environment evokes a possibility of the local corrosion which limits seriously exploitation of this material in aggressive conditions. The presented paper is focused on the pitting corrosion resistance (“as received” steel surface) in 1M chloride solution (pH=1.2) at a common (20 °C) and an elevated (50 °C) ambient temperatures. 24-hours exposure immersion test (ASTM G48) and cyclic potentiodynamic test (ASTM G61) are used as the independent test methods. The exposure immersion test is carried out with cross-rolled and longitudinally rolled specimens and the effect of direction of rolling on the resistance to pitting is studied.
Assessment of the Effect of the Pre-cast Beams IG Axial Spacing on the Effort Bridge Span
Authors: Gąćkowski Roman , Selejdak Jacek 
Published: October 2019

Abstract
In designing of reinforced concrete bridges are often used pre-cast of pre-tensioned or post-tensioned prestressed members. In professional practice, when designing bridge span pre-cast of pre-tensioned prestressed beams IG type, different axial beams spacing’s are used and they are joined by a reinforced concrete slab. The paper presents a comparative analysis of an influence of the axial spacing of IG type beams in the cross-section of the bridge, on the bridge span effort, using standards PN-85/S-10042 and PN-EN 1992-2:2010. The optimal axial spacing of pre-cast IG type beams is presented, while maintaining the standard conditions of ULS (Ultimate Limit State). Such a solution has a positive impact on the costs of the entire project, significantly lowering the global investment cost.
