Comparison of the effectiveness of blood transfusion and reinfusion

Studies by atomic force and scanning electron microscopy have shown that erythrocytes of foreign blood have morphological defects. The sequestration of foreign erythrocytes makes it difficult for the erythron to selfrepair. The actual solution to this problem is the application of the blood reinfusion technique using the Cell Saver apparatus. Transfusion of autoerythra suspension, harvested using the Cell Saver apparatus during the operation, stabilizes red blood counts in the early post-transfusion period in patients and reduces the manifestation of massive hemotransfusion syndrome. Hardware reinfusion of erythrocytes is effective and safe for massive blood loss in obstetrics. Reinfusion dictates the need for parallel correction of all blood parameters. Application of the principles of patient blood management can reduce the transfusion load, improve the quality of medical care.

Hegel’s Answer to the Agrippian Trilemma

In his Encyclopedia, the late Hegel makes the highest demands on truth and justification from the first paragraph onward. With this, Hegel takes up the skeptical challenge and believes that he can overcome this problem. However, it is not easy to see how Hegel tries to meet this challenge in the Science of Logic, which plays a fundamental role in Hegel’s encyclopedic project. The present article argues that the question of the justification of the claim to truth is a fruitful perspective for the interpretation of the Science of Logic. For this purpose Hegel’s answer to the Agrippan Trilemma is examined, which P. Franks analyzed as a basic problem for Classical German Philosophy. One possible interpretation of Hegel sees him solving the skeptical trilemma at the beginning of the Logic. The article argues against this possibility that the Logic of the Concept contains Hegel’s actual solution. This solution consists in (1) that the concept represents the principle of logic and (2) that the concept itself must be presented in the form of an apagogical argument. Finally, the article gives a reason why Hegel sees an analogy to the ontological argument in this attempt of an ultimate justification.

Construction of an Approximate Analytical Solution for Multi-Dimensional Fractional Zakharov–Kuznetsov Equation via Aboodh Adomian Decomposition Method

In this paper, the Aboodh transform is utilized to construct an approximate analytical solution for the time-fractional Zakharov–Kuznetsov equation (ZKE) via the Adomian decomposition method. In the context of a uniform magnetic flux, this framework illustrates the action of weakly nonlinear ion acoustic waves in plasma carrying cold ions and hot isothermal electrons. Two compressive and rarefactive potentials (density fraction and obliqueness) are illustrated. With the aid of the Caputo derivative, the essential concepts of fractional derivatives are mentioned. A powerful research method, known as the Aboodh Adomian decomposition method, is employed to construct the solution of ZKEs with success. The Aboodh transform is a refinement of the Laplace transform. This scheme also includes uniqueness and convergence analysis. The solution of the projected method is demonstrated in a series of Adomian components that converge to the actual solution of the assigned task. In addition, the findings of this procedure have established strong ties to the exact solutions to the problems under investigation. The reliability of the present procedure is demonstrated by illustrative examples. The present method is appealing, and the simplistic methodology indicates that it could be straightforwardly protracted to solve various nonlinear fractional-order partial differential equations.

Peran Kaidah Fikih dalam Aktualisasi Hukum Islam: Studi Fatwa Yusuf Al-Qaradawi tentang Fiqh Al-Aqalliyat

Fiqh as a product of Islamic law must always be up to date to become a religious solution for society. This fact requires scholars to have high creativity in doing ijtihad so that actualizing of Islamic law can be realized perfectly in today's contemporary era. One of the scholars who focus on the actualization of Islamic law is Yūsuf al-Qaraḍāwī. His fatwas, which contain actualizations of Islamic law, are fatwas on Muslim minority issues (fiqh al-aqalliyāt). This study highlights the role of Islamic legal maxims (al-qawāid al-fiqhiyyah) in al-Qaraḍāwī's fatwa on fiqh al-aqalliyāt. The data comes from books and articles related to the theme. This research proves that Islamic legal maxims have a dominant role in the methodology of al-Qaraḍāwī’s ijtihad. In establishing his fatwa, al-Qaraḍāwī based the argument on the opinion of the islamic scholars in accordance to the basic values of fiqh principles. Therefore, his fatwa can be an actual solution for minority Muslim communities in Western countries. Thus, Islamic legal maxims (al-qawāid al-fiqhiyyah) play a role in controlling and systematizing the laws around fiqh al-‘aqalliyāt so that it always leads to convenience and avoids difficulties.

Microsocial Determination of Coping Strategies of Youth in Situations of Family Interpersonal Conflicts

The article discusses the results of the author's research obtained during the implementation of socio-psychological support of the individual in difficult life situations for several years. It is shown that coping strategies in situations of interpersonal intra-family conflicts in young people aged 18-20 years are mainly determined by the experience of their microsocial interaction. It is revealed that the accumulation of experience of microsocial interaction among young people aged 18-20 leads to an increase in the tendency to prefer coping strategies that are not related to the actual solution of the problem in the intra-family conflict. The results obtained have a pronounced practical significance and justify the need for training in constructive coping behavior in situations of intra family conflicts

Considering Section Balance in an Integer Optimization Model for the Curriculum-Based Course Timetabling Problem

University course timetabling is a complex and time-consuming duty that every educational institution faces regularly. It consists of scheduling a set of lectures in predefined time slots so as to avoid student conflicts, meet teacher and room availability, and manage several institution-specific operational rules. In this paper, we schedule courses based on a curriculum, that is, before the students’ registration. Unlike other curriculum-based models, the proposed model considers two practical aspects when managing the conflicts between lectures: (i) it schedules sections of subjects so that each section is evenly likely to be registered by the students, and (ii) it considers the failure rates and periodicity a subject is taught. We present a multi-objective integer programming model that maximizes the use of specific time slots, the symmetry in which the lectures of a course are scheduled during a week, and the flexibility for straggler students to take courses. The model is solved using commercial software, and it is applied to a real course-timetabling problem. We show the advantages of its use by comparing the model’s solution with the actual solution obtained by the manual scheduling.

A function fitting method

In this article, we describe a function fitting method that has potential applications in machine learning and also prove relevant theorems. The described function fitting method is a convex minimization problem which can be solved using a gradient descent algorithm. We also provide qualitative analysis on fitness to data of this function fitting method. The function fitting problem is also shown to be a solution of a linear, weak partial differential equation (PDE). We describe a simple numerical solution using a gradient descent algorithm that converges uniformly to the actual solution. As the functional of the minimization problem is a quadratic form, there also exists a numerical method using linear algebra.

Assessing the Unmanned Aerial Vehicles' Surveillance Problems and Actual Solution Options from the Different Stakeholders' Viewpoint

The problems related to the integration of the unmanned aerial vehicles into national airspaces is one of the main topics that the scientific researchers are dealing with these days. Despite that, none of them are investigating the UAVs from the surveillance point of view. For that reason, highlighting the problems that have to be dealt with and assessing them through a holistic approach is the aim of the paper. Therefore, the paper takes the different stakeholders view and identify the key factors that have to be taken into account. The authors propose the surveillance technologies that can be considered and evaluated them along the revealed factors through a global view. The results can be applied as a base for the further research in UAVs surveillance domain.

PHILOSOPHICAL AND METHODOLOGICAL FOUNDATIONS OF PSYCHOLOGY: PROBLEMS AND WAYS TO SOLVE THEM

At the beginning of its formation psychology used to be a philosophical discipline; permanent methodological crisis started along with psychology standing apart as a separate science. The common questions that defined methodological crisis of psychology are its philosophical foundation and subject of study. This article contains information about one of the attempts to find a solution to listed problems on materials of the history of Russian psychology. The path of psychology formation on a basis of Marxist philosophy wasn’t easy; there were many debates and arguments upon a subject. This way wasn’t a coincidence, it was conditioned both social processes and inner logic of this science development. The chosen historical example shows the connection between philosophy and psychology. This connection back there was reasoned by the fact that at first there was a need to defend the materialistic approach to the understanding of psychological. Currently, the question of the philosophical basis of psychology is being ignored, though in the Soviet era for a short period this crisis was overcome and methodology that was constructed allowed to achieve expected results. The methodological crisis arose again with the political system being demolished. Pluralistic methodological positions that existed afterwards couldn’t grand the actual solution, they only acknowledged the existence of a multiplicity of psychologies. One of the alternatives to further development would be the construction of an independent discipline going by the name of a philosophy of psychology. Psychology needs philosophical conceptualization and a view from the meta on its history and future evolution. This discipline can stop arguments that went on for years. We though suppose that the construction of this discipline needs full scientific cooperation including support from those who work in the field of psychology, philosophy and methodology. Constructing unified methodological and communicative space on a basis of the philosophy of psychology can help with solutions to practical tasks such as the question of consciousness or the development of artificial intelligence.
