Published: September 2021

Cancer is a group of diseases with uncontrolled cellular proliferation. Breast cancer accounts for 25% of all cancer deaths in females worldwide. Monoclonal antibodies are used for the detection of tumor markers in order for rapid diagnosis and understanding of the nature of cancer at molecular level. On co-fetal antigens like carcinoembryonic antigen 15-3 (CA 15-3) are a new generation of clinically useful tumor markers. Elevated levels of CA 15-3 are related to stages in primary breast cancer, tumor size and nodal status. Significantly elevated sialic acid concentrations havebeen found in breast cancer patients and show correlation with tumor stage. Although total sialic acid has been used as general cancer marker but its role as diagnostic and prognostic marker has not been reported. Objective: This project was designed to study the sensitivity and specificity of sialic acid in breast cancer patients and was compared to CA 15-3, which is one of the most specific markers of breast cancer. Study design: Comparative study. Setting: Shaikh Zayed Medical Complex. Material and Methods: 66 breast cancer patients and 30 normal individuals (controls) were included in the study to compare serum sialic acid with CA 15-3 as tumor marker. Sialic acid was estimated by colorimetric method while CA 15-3 by Enzyme-Linked Immunosorbent Assay. Results: The sensitivity and specificity of CA 15-3 in breast cancer patients was 62.5% and 80% while that of sialic acid was 62% and 76% respectively. The sensitivity of CA 15-3 and sialic acid in patients with ductal breast carcinoma was 62.5% and 54.16% whereas the specificity of CA 15-3 and sialic acid was 80% and 76% respectively. The sensitivity of CA 15-3 and sialic acid in patients with lobular breast carcinoma was 83.33% and 75% whereas the specificity of CA 15-3 and sialic acid was 80% and 76% respectively. Conclusion: It was concluded that sialic acid can be used as a tumor marker in breast cancer patients and has sensitivity and specificity similar to CA15-3. However, CA 15-3appears to have better predictive value.
Teología de la Liberación: influencias, características y las tensiones con el Vaticano
Authors: González Daiana Marlén 
Published: September 2021

<p class="Default"> El surgimiento y el desarrollo de la Teología de la Liberación en América Latina supuso una importante novedad para la Iglesia Católica y para la Teología tradicional. A los teólogos de la liberación se les reconoce por su gran compromiso pastoral, social y político. La Teología de la Liberación se presenta como una alternativa de interpretación bíblica y de vida cristiana desde la experiencia de los países latinoamericanos. Se orienta también a promover un mayor compromiso y participación en los procesos políticos de liberación de estos países y, por esta razón, lleva a cabo la revisión crítica del rol que la Iglesia debe tomar al respecto. Es conocida por su opción en favor de los pobres y los oprimidos a quienes considera los principales perjudicados por la injusticia y pobreza que atraviesa Latinoamérica.</p><p class="Default">Lo anterior no siempre ha sido bien recibido por los clérigos más ortodoxos, quienes vieron en sus ideas un fuerte sesgo marxista. Por ello, en torno a la Teología de la Liberación se han generado grandes disputas, muchas de ellas aún vigentes. En este trabajo nos proponemos retomar una de esas disputas mediante el análisis de dos textos que son claves para comprender al movimiento teológico y las polémicas que se suscitaron en el interior de la Iglesia Católica. El escrito se desarrollará a partir de una lectura del Documento Conclusivo de la Segunda Conferencia del Episcopado Latinoamericano (1968) y de la Instrucción sobre algunos aspectos de la “Teología de la Liberación” (1984) del Cardenal Joseph Ratzinger, quien intentó advertir sobre las posibles “desviaciones” presentes en la Teología de la Liberación.</p>
Deshacerse del marxismo: 3 ejes para una lectura foucaultiana del poder
Authors: Chera Ian 
Published: September 2021

<p class="Default"> La propuesta que engloba el conjunto de este escrito: tres ejes para una lectura foucaultiana del poder implica cierto análisis reconstructivo de diferentes elementos presentes en las distintas obras, conferencias, cursos y entrevistas del filosofo francés Michel Foucault, para comprender en qué medida se enfrenta a la tradición marxista y en cuál otra propone algo distinto. En términos procedimentales se intentará bosquejar desde los tres ejes estimables que configuran la visión marxistas del poder: el Estado, la dominación burguesa y la represión, tres nodos interpretativos que harían posible deshacerse: la centralidad, la funcionalidad y la negatividad, y tres nodos propositivos para abordar el poder de otra forma: regionalidad, guerra, positividad. Tal tarea torna imprescindible examinar aquellos lugares donde convergen los tres ejes y las especificidades de cada uno, al mismo tiempo que la contrastación con otras lecturas -principalmente de Gilles Deleuze y Étiènne Balibar- para dar mejor soporte a esta propuesta. Finalmente, se configurará el mapa general de la lectura con sus diferentes conexiones.</p>

Authors: Khuda Zh. , Tonkonoh E. 
Published: September 2021

The article considers the main problems characteristic of mathematical education in higher technical institutions. The purposes and tasks of training of higher and applied mathematics of students of technical specialties, and also separate features of training of students of an electromechanical direction to mathematical disciplines are covered.
Achieving the current goal of modernization of mathematics education in technical universities is associated with the solution of a number of pedagogical issues. The problem is the systematic and comprehensive reform of mathematics education in accordance with current trends in both production and education. The content of mathematical education needs to be changed, in particular: curricula and study programs, the level of educational material, methods, teaching technologies, procedures for diagnosing the quality of teaching. Curricula of specialties should contain mathematical disciplines, which include special mathematical sections that allow to provide quality training of professionally oriented disciplines and allow to form mathematical competence as part of the professional competence of the future professional. The solution of the problem of formation of mathematical competence as a part of professional competence of graduates of technical universities becomes actual. This necessitates the strengthening of the professional orientation of the content of teaching mathematics, the intensification of the activity approach in learning technologies, the importance of the formation of appropriate value orientations of students. Actualization of students' activities strengthens the role of such educational technologies as multilevel learning, independent work of students, computer technology, project activities. Thus, additional mechanisms are created for the systematic acquisition of knowledge and skills by students, for the systematic control of the formation of mathematical competencies, for a differentiated approach to learning.
To improve the quality of mathematical education of students of technical universities it is necessary to pay attention to the construction of mathematical models of real production problems and methods of their solution. The use of mathematical modeling methods leads to the need for a deeper study of the relevant sections of mathematics. This approach changes the structure of training, gives the opportunity to use more independently the independent work of students. At the same time, students' knowledge will be deeper and stronger.
UNIVERSAL METHOD OF CALCULATION OF MULTISPAN BEAMS

Published: September 2021

The supporting structures of machines and mechanisms of metallurgical equipment, which are characterized by large dimensions, in the calculation scheme can be reduced to multispan beams, which are statically indeterminate. Traditionally, the disclosure of their static uncertainty is based on the graphoanalytical method, which is called "Equation of 3 moments". According to this method, the equations of three points are solved by constructing intermediate epure of bending moments, finding their areas and position of the centers of gravity. These procedures lead to an unreasonable increase in time to solve the problem. It is advisable to have an analytical method for detecting static uncertainty of multispan beams, which would be free from graphical constructions and would significantly reduce the time to solve the problem.
At the present stage, the calculation of complex spatial structures is carried out using the calculation and software systems "LIRA", "SCAD" and others. However, this in no way limits the need for the application in engineering practice of simple analytical methods, which include a universal method for detecting static indeterminateness of multispan beams.
Additional, to the static equations, the equations of displacement are compiled using the universal equation of the bent axis of the beam, and the number of beams can be any large. Different variants of boundary conditions are considered. The results of the considered examples prove the independence of the values ​of "extra" unknown from the stiffness of the beam.
The universal method is quite optimal, as it uses a very simple universal equation of the bent axis of the beam and, with each subsequent additional equation of displacement differs from the previous one only by adding another item with a new load. This approach provides the optimal solution to almost any problem, by revealing the static indeterminateness of multispan beams.
ALGORITHM FOR SYNTHESIS OF QUASI-OPTIMAL IN SPEED THIRD-ORDER SYSTEMS WITH APERIODIC SLIDING MODE
Authors: Derets O. , Sadovoi O. , Derets H. 
Published: September 2021

The relevance of the work is due to the growing requirements for the dynamic characteristics of electric drives. In particular, together with the requirements of ensuring high accuracy and maximum at given speed limits, a typical task of designing such systems is the mandatory formation of transition diagrams in the form of monotonic time functions.
The purpose of this study is to develop an adaptive algorithm for the synthesis of the third-order sliding mode control systems based on the method of N-i switching. Changing the shape of transient trajectory depends on the magnitude of the movement, which requires adaptation of the settings of the control system of the electric drive to the features of the current positioning mode.
On the basis of the N-i switching method, an algorithm for synthesizing the parameters of a re-lay control system with cascade-subordinated structure, ensures non-oscillatory initiation of a sliding mode at various positioning modes, has been created. It is constructed by integrating the results of a number of previous works, in which the synthesis of relay control systems based on the analysis of the roots of the sliding equation of the position regulator is performed. This algorithm cannot be formally considered as an optimization tool due to the incompatibility of this problem with the aperiodization taken as the purpose, which comes about for certain forms of transient trajectories. But for such cases, the loss of performance relatively optimal one is negligible. Thus, the result of the application of the proposed algorithm in most practically significant cases is an optimal third-order system with aperiodic entry into the sliding mode. When controlling the electric drive, such a system will ensure the monotonous nature of the movement of the working body of the electromechanical system. The developed block diagram is focused on the practical implementation of the algorithm by the software of controllers of precision electric drives.
