Authors: Staniszewska Izabela Anna , Staszyński Szymon , Zielińska Magdalena
Published: December 2020

The aim of study was to determine the effects of sonication (S), convective freezing (F), convective freezing preceded by sonication (SF) as well as cryogenic freezing (N) on the osmo-microwave-vacuum drying kinetics, energy usage and properties of dried cranberries such as moisture content, moisture diffusion, water activity, density, porosity, thermal conductivity, thermal diffusivity, volumetric heat capacity, lightness, redness, yellowness, total differences in color, saturation and hue, hardness, cohesiveness, springiness, and chewiness. Osmo-microwave-vacuum drying of cranberries took from 13.5 to 16.0 min. All initial treatments increased the moisture diffusivity and thus reduced the drying time. The most energy effective method was osmo-microwave-vacuum drying preceded by sonication (S) of fruits. Osmo-microwave-drying of cranberries subjected to convective freezing preceded by sonication (SF) resulted in the highest lightness (32.5 ± 0.5), redness (33.9 ± 0.7), and yellowness (11.3 ± 0.5) of fruits, as well as the lowest cohesion (the lowest resistant to stress associated with manufacturing, packaging, storage, and delivery). The lowest hardness, i.e. 12.3 ± 0.4 N and the highest cohesiveness and springiness, i.e. 0.38 ± 0.02 and 0.74 ± 0.03 of dried fruits, were noted for berries subjected to initial cryogenic freezing (N). Cryogenic freezing (N) combined with osmo-microwave-vacuum drying resulted in the largest color changes of fruits and the highest thermal conductivity. Sonicated and convectively frozen (SF) fruits were characterized by the highest thermal diffusivity. Sonication (S), convective freezing (F) and their combination (SF) significantly reduced the volumetric heat capacity of cranberry fruits.

Authors: Подымова Н.Б. , Калашников И.Е. , Кобелева Л.И.
Published: December 2020

A laser optoacoustic method for quantitative porosity assessment of cast particulate reinforced metalmatrix composite materials is proposed and experimentally realized. The method is based on statistical analysis of the amplitude distribution of backscattered broadband pulses of longitudinal ultrasonic waves in the studied materials. Laser excitation and piezoelectric detection of ultrasound are realized by one-side access to a tested object using a special laser-ultrasonic transducer. Stir cast siluminmatrix composites reinforced with the SiC micro particles (volume fractions 0.033–0.135) and in-situ reactive cast aluminummatrix composites reinforced with the Al3Ti intermetallic particles (volume fractions 0.04–0.115). For both types of composites, the amplitude distribution of backscattered ultrasonic signals is approximated by the Gaussian distribution function applicable for statistics of large number of statistically independent variables. The derived empirical dependence of the half-width of this distribution on the volume porosity of two different types of composites is approximated by one and the same linear function independently of the fabrication technique, as well as on the type, size, and volume fraction of reinforcing particles.

The paper proposes algorithms for signals processing obtained by the multiple shadow method using Rayleigh waves propagating in the direction of the envelope pipe, and an electromagnetic-acoustic method of emission-reception. The results of a study of the sensitivity of the method to artificial and natural surface and near-surface defects of workpieces of drill pipes in two frequency ranges are presented. As informative parameters, it is proposed to use the multiple coefficient of detectability, as well as the probabilistic characteristics of dispersion, asymmetry and kurtosis in the analysis of a series of multiple passes, and the criteria for rejection are substantiated. The research results can be used in the development of automated installations and methods for monitoring pipes of small diameter.

Published: December 2020

The study sought to explore students' views on the utility of non-formal education in addressing the school dropout phenomenon at secondary school level. Qualitative research approach was adopted and a case study design was utilised. The population consisted of all the students in the non-formal programme at the school from which a sample of 11 students (2 male and 9 female) was selected through purposive stratified sampling technique. Data were gathered through structured in-depth interviews and focus group discussions. Non-formal education was seen to address the school dropout phenomenon by providing school drop outs with an opportunity to continue their education and hence becomes a form of empowerment. A number of challenges such as lack of adequate tuition in some subjects, lack of conducive learning environment as well as negative perception of non-formal education held by pupils in the formal stream and community members were identified. The study recommends that the Ministry of Primary and Secondary Education should review the staffing situation in schools to ensure the availability of teachers in the various subjects in the non-formal stream. Schools should make an effort to provide appropriate learning facilities for students in the nonformal stream. Furthermore, schools should conscientise their communities on the importance of non-formal education.

Published: December 2020

The most common occupational diseases in the industry are mainly due to the non-compliance with the employer's obligation to provide appropriate training in the workplace. This is often performed only by signing training forms only formally. With this fact in mind, we analyze in this paper the occupational diseases in industry specific to Brașov County, presented in the reports of Brașov Labor Inspectorate, from 2005 to 2019. This study was conducted based on the number of occupational diseases due to silicosis, related to the total number of occupational diseases in Brașov County (study period between 2005 and 2019). Given the state of emergency
generated by the COVID-19 pandemic, in order to prevent the spread of this virus and to carry out activities using work from home, telework, and to avoid the interaction between workers as much as possible, online communication with employees is considered as being the only way that allows at the same time both the observance of the measures imposed to prevent the spread of the virus and the implementation of the obligations regarding training on occupational safety and health, which the employer has according to the laws in force. In this context, analyzing the values obtained from the experimental data (number of occupational diseases due to
silicosis, related to the total number of occupational diseases in Brasov County) it is identified and solved in the paper the use of online environment, especially in remotely training the workers, who have the opportunity to receive training documents, analyze them, sign them electronically and send them to the employer in electronic format and in this way, being trained even in special situations.

A crônica: Formação de leitores no 9º ano do Ensino Fundamental
Authors: Lima Élida Valeria da Silva , Caria Josiano Regis
Published: December 2020

A leitura é o eixo norteador do ensino em Língua Portuguesa e, como tal, precisa tornar-se objetivo de ensino, pois trata-se de um processo cognitivo, histórico, cultural e social de produção de sentidos. Conceber a leitura desse modo remete-nos a pensar em como organizar o seu ensino. Se os sentidos não estão prontos no texto, é preciso contribuir para que os alunos criem boas estratégias para estabelecer relações necessárias à compreensão. Tais estratégias perpassam pelos gêneros textuais e o trabalho planejado através deles, especificamente, a crônica. Os objetivos aqui postulados incluem conhecer essas estratégias de leitura para a formação de leitores críticos dos alunos de uma turma de 9. ano do Ensino Fundamental em uma Escola Estadual no Município de Presidente Figueiredo/AM. O método utilizado é o da pesquisa exploratória mista (quantitativa e qualitativa) de caráter indutivo, que nos levou aos resultados elencados, mediante a aplicação de questionários. O tema, longe de ser esgotado, merece ser mais discutido e explorado, uma vez que a formação de leitores críticos é o cerne da questão mais discutida entre especialistas e educadores da Educação Básica.

Published: December 2020

Este artículo tenía como objetivo aportar un enfoque en términos de derecho de propiedad y sus reflejos directos e indirectos en el pleno ejercicio del dominio. Sabiendo que no existe ningún bien sin posesión o posesión sin propiedad, en este contexto se verificó que el derecho a la propiedad y el derecho de propiedad son autónomos entre sí, recibiendo un trato diferenciado debido a su elasticidad o alcance en el que implica en otras ramas del derecho. Estos eran los objetivos generales y a este paso se sugirió la siguiente posibilidad en relación con el objetivo específico: ¿Se habrían inspirado las leyes en la Luz del Creacionismo? ¿Cuáles son los daños derivados de la (Ley No 14.223/2006) en relación con el derecho a la propiedad y a la posesión? En vista de la hipótesis, este artículo se hizo relevante por el contenido histórico judío-cristiano, respetando la libre voluntad del Espíritu de todo ser humano. Por lo tanto, la investigación se caracteriza como un método inductivo y nada impide la integralidad de otros métodos por vías accidentales o no accidentales. La investigación tuvo como fuente de referencias: la ayuda de la doctrina, la jurisprudencia, las leyes y el CF/88. Por lo tanto, debido a que no tiene un propósito apriorístico, este artículo está abierto para la exploración futura.

Authors: Castillo Aldo , Molina Cesar , Reyes Edinson , Portilla Hans , Arévalo César , Vega Juan , Vega Alexander
Published: December 2020

The present research evaluated the effect of the nitriding time in plasma in the range of 5 to 15 hours, on the hardness profile of the cross section of stainless steel samples AISI 431; in addition to taking and differentiating the data on surface hardness, effective layer depth and nitride layer thickness. The nitriding process was by plasma, the process temperature was kept constant at 400 °C. The evaluated samples were machined (rolled and countersigned), and were left in one inch diameter and one inch in length. The times of 10 and 15 hours of nitriding time were obtained by accumulating time of 05 hours of nitriding per week; the hardness profiles were obtained by using the LECO model LMV-50V micro durometer; The ASTM E3-91 standard was used to collect the aforementioned hardness data, from these it was possible to determine that the maximum surface hardnesses are (1053, 1252 and 1327) HV-0.01, for nitriding times of (5,10 and 15) hours respectively, the average effective layer thicknesses were (37.75, 33 and 28.75) μm; while the nitride layer thicknesses were (4.9, 7.03 and 10.7) μm corresponding to times of (5, 10 and 15) hours respectively. The hardness in the core after the nitriding treatment was kept in the range of (275-277) HV-0.01. These values were determined by microscopic evaluation of the tested samples, the metallography reagent used was 3% Nital by electrolytic attack for 3 minutes in each case. The statistical analysis corresponded to Student's “t” tests, in the form of pairwise comparison, from which the non-significant difference between repetitions and the significant difference between the different levels of study were determined.

In a recent paper, “Environmental DNA: What's behind the term? Clarifying the terminology and recommendations for its future use in biomonitoring”, Pawlowski et al. argue that the term eDNA should be used to refer to the pool of DNA isolated from environmental samples, as opposed to only extra-organismal DNA from macro-organisms. We agree with this view. However, we are concerned that their proposed two-level terminology specifying sampling environment and targeted taxa is overly simplistic and might hinder rather than improve clear communication about environmental DNA and its use in biomonitoring. Not only is this terminology based on categories that are often difficult to assign and uninformative, but it ignores what is in our opinion the most important distinction within eDNA: the type of DNA (organismal or extra-organismal) from which ecological interpretations are derived.

Published: December 2020

The article examines the theoretical and instrumental bases of formation of the organizational-economic mechanism. The conceptual model of the process-oriented management of economic potential of enterprise is elaborated, which consists of aim, goals, methods, defining the relationships of subjects, functions and objects of management. The characteristics of these relationships are conditional upon the influence of the external and internal environment, taking into account the relevant hierarchy and management objectives. According to the results of the research, approaches to the formation of the organizational-economic mechanism and the process-oriented management are defined, which is based on general principles (systematicity, dynamicity, complexity, efficiency, purposefulness, scientific validity) and specific principles (completeness of coverage and involvement of economic resources, conformity to plan and budgeting, innovative development, efficiency of use, effective administration, control and coordination). The proposed principles are the main ones for determining the key indicators in assessing the economic potential of the enterprise, fixing to some extent the main stages of its implementation in space and time. The author defines that the organizational-economic mechanism of the process-oriented management is carried out on the basis of the application of management methods, that is, a set of certain techniques of influence on the management object, which contribute to the achievement of the targets. The main objectives of the organizational-economic mechanism of the process-oriented management of economic potential should be: formation of a development strategy on the basis of consistency of economic interests, creation of conditions for the efficient implementation of each component of economic potential, development and implementation of measures to improve the efficiency of its use, organization of assessment of the effectiveness of management influences. The proposed organizational-economic mechanism is a basic platform for determining the system of elements, the nature of the process of their interaction, and the development of practical recommendations as to activities of enterprises.

The article is aimed at offering and highlighting the results of the authors’ research on existing approaches and methods for change management, as well as to finding ways to improve the effective implementation of changes at the enterprise. The subject of the research was methodological approaches to the process of change management at the enterprise. The research was carried out by analyzing scientific works of foreign and domestic scholars on the topic of the article. The concept of change management is substantiated, which is based upon the possibility to reproduce the model of successful changes on the basis of specific instruments that allow to effectively implement changes. In the course of the analysis, the main competitive advantages that the enterprise can get in the implementation of effective change management were allocated. The models that allow efficient implementation of changes are defined. The choice of a particular model depends on the nature of the enterprise’s work and its chosen development strategy. It is proposed to classify approaches to change management by the nature of changes and the nature of management. Also noted is the necessity to distinguish between approaches to development management by the nature of planning, organization, management and control at the enterprise. In addition to approaches to change management at enterprises, it is advisable to consider existing models of implementation of changes, taking into account the specific situation and the desired results. The authors developed and proposed the process of managing changes at the enterprise in the form of a specific algorithm. As a result, the direction of further development of classification of approaches to change management is obtained. The authors propose their own vision of the change management process, which is advisable to present in the form of a specific algorithm for implementing and managing changes at the enterprise. Prospects for further research are coverage of applied aspects of change management at domestic enterprises.
