Research on sorption properties of phosphoric production slag-waste

On the territory there are phosphorus-containing wastes - phosphorus slags, the basis of which is volostanite. The study of phosphorus slag as a uranium sorbent is of theoretical and practical interest. In the course of the research, comparable data were obtained on the sorption of the initial and activated slag by different reagents. The optimal conditions for the activation of phosphorus slag in order to increase its sorption properties have been determined

FIT FOR THE FUTURE - MODERNISATION OF MASTER CURRICULUM IN ICT FOR ENHANCING STUDENT EMPLOYABILITY IN BELARUS

The Belarusian ICT industry grows fast, but the full potential has not been reached yet. To increase the ICT industry’s position as a central soil for the Belarusian economy, factors that hinder further growth, need to be identified and improved. Two of such factors are the inefficient dialogue between the ICT industry and higher education and a rather passive role of universities in framing trends on the market. This paper describes the concept and the implementation plan of the Erasmus+-project “Modernisation of Master Curriculum in ICT for Enhancing Student Employability in Belarus” (MaCICT). MaCICT is aimed to enhance the employability of ICT master students, foster entrepreneurship and establishment of SMEs in the ICT industry, and to upscale the position of higher education. For this, MaCICT updates the ICT study programmes to become more labor market and society oriented, practice-based, and student-centered. This forces universities to combine the traditional professional skills and competencies with soft and transferable skills and to focus more on multidisciplinary studies and internationalization of the study environment

Role and application of three-dimensional transthoracic echocardiography in the assessment of left and right ventricular volumes and ejection fraction: a UK nationwide survey

Three-dimensional echocardiography (3DE) imaging has permitted advancements in the quantification of left ventricular (LV) and right ventricular (RV) volumes and ejection fraction. We evaluated the availability of 3DE equipment / analysis software, the integration of 3DE assessment of the LV and RV in routine clinical practice, current training provisions in 3DE, and aimed to ascertain barriers preventing the routine use of 3DE for volumetric analysis. Through the British Society of Echocardiography (BSE) regional representatives’ network, echocardiographers were invited to participate in an open online survey. A total of 181 participants from echocardiography departments in the United Kingdom (UK), the majority from tertiary centres (61%), completed the 28-question survey. For 3DE quantification, 3DE-LV was adopted more frequently than 3DE-RV (48% vs 11%, respectively). Imaging feasibility was a recognised factor in 3DE RV and LV adoption. Many respondents had access to 3D probes (93%). The largest observed barriers to 3DE routine use were training deficiencies, with 83% reporting they would benefit from additional training opportunities and the duration of time permitted for the scan, with 68% of responders reporting allowances of less than the BSE standard of 45–60 min per patient (8% < 30-min). Furthermore, of those respondents who had undertaken professional accreditation, competence in 3DE was not formally assessed in 89%. This UK survey also reported good accessibility to magnetic resonance imaging (72%), which was related to overall 3DE adoption. In summary, although 3DE is now readily available, it remains underutilised. Further training opportunities, integrated formal assessment, improved adoption of BSE minimum recommended scanning times, alongside industry and societal support, may increase 3DE utilisation in routine practice

Creative Techniques in the Framework of Market and Evolution

This paper tries to reframe the man-machine problem, which has frequently changed throughout history. Originally, a machine was a helper of man, but later became its competitor and substitute. As a consequence of this, man has been pushed out of production and possibly, out of life itself. For today, nearly all the man’s functions – except for consumption and creativity – can be furnished by machines. Creativity should have a special place because it is the last “shelter” of man in the conflict with machine. Almost every other faculty of man has more or less been simulated by technology. There are some key questions to be answered: Whom do the creative techniques serve? Is the target group the men or machines

Multimodality Imaging Assessment of Tetralogy of Fallot: From Diagnosis to Long-Term Follow-Up

Tetralogy of Fallot (TOF) is the most common complex congenital heart disease with long-term survivors, demanding serial monitoring of the possible complications that can be encountered from the diagnosis to long-term follow-up. Cardiovascular imaging is key in the diagnosis and serial assessment of TOF patients, guiding patients’ management and providing prognostic information. Thorough knowledge of the pathophysiology and expected sequalae in TOF, as well as the advantages and limitations of different non-invasive imaging modalities that can be used for diagnosis and follow-up, is the key to ensuring optimal management of patients with TOF. The aim of this manuscript is to provide a comprehensive overview of the role of each modality and common protocols used in clinical practice in the assessment of TOF patients

Revisiting the Kazakhstan natural sorbents modification

Kazakhstan ranks second in the world in natural uranium reserves and a leading position in its production. Hydrometallurgical processing of uranium raw materials results in a significant amount of liquid technogenic wastes containing radionuclides. Sorption cleaning methods for these wastes are the most effective ones. However, the high cost of synthetic sorbents and the low sorption capacity of natural ones is a deterrent to their use. So, to increase the sorption capacity of natural sorbents by their modification is an urgent problem. In this paper, a method to modify Kazakhstani natural zeolite was proposed by us and previously not investigated. Also the data of physicochemical studies of the initial raw material and the modified product was given and the increase in the natural sorbent specific surface in the modification process was demonstrated

Features of morphological and ultrastructural organization of the cornea (literature review)

The human cornea – the anterior fibrous membrane of the eye, is a unique ordered optical-biological system that is avascular, saturated with nerve endings, includes tissue-specific cells, consists mainly of various types of collagen. An exceptional feature of the collagen layers of the cornea, including the collagen plates of the stroma, is transparency, which provides physiological refraction and light transmission due to the stable supporting properties of the cornea. The data on the morphological structure of the cornea, which is an important element of the optical system of the eye, are of considerable interest not only from theoretical, but also from practical positions. This is due to the fact that the identification of the first signs of deviation from normal physiological morphological and ultrastructural criteria in the cornea allows us to establish the nature of its pathological changes, which can be caused by both hereditary predisposition and local and general disorders. It has been shown that the thinning of the layers of the cornea, a decrease in the density of endotheliocytes or keratocytes signal the development of dystrophic processes in it. In addition to evaluating quantitative morphometric data, changes in qualitative ultrastructural indicators play an important role. In particular it was found that a decrease in the density of endothelial cells is accompanied by an increase in their size and a decrease in the cell nucleus. In addition, a number of degenerative pathological conditions are characterized by a decrease in the diameter of collagen fibrils and a change in the density of fibrillary packaging.This literature review presents basic information, features of morphology, ultrastructural organization and functional purpose of layers and cells of the human cornea
