ALUMINUM AND STEEL WELDING WITH 500 W FIBRE LASER
Get PDFThe study of the process of laser welding of various aluminum-steel joints is necessary to promote the possibility of realization of new products and designs in instrumentation and mechanical engineering. Laser welding, due to its many advantages, is considered a very promising process of joining different materials, although its application in industry is still limited. Welding aluminum with steel using laser sources is a challenging task mainly due to the formation of brittle intermetallic joints (IMC) at the joint interface. This paper aims to give a brief overview of some new research on laser welding of aluminum to steel, as well as to point out some of our initial laboratory research in this direction.[1
CLOUD COMPUTING
Get PDFMūsdienās mākoņdatošana ir svarīga lietotāju un uzņēmumu dzīves sastāvdaļa. Pateicoties mākoņdatošanai, cilvēkiem ir visas iespējas saglabāt savus datus mākonī, pārsūtīt lietojumprogrammas utt. Mākoņdatošana ļauj uzņēmumiem saglabāt naudu par dārgu aparatūru un programmatūru, kā arī ietaupa laiku uzņēmuma darbiniekiem. Mākoņdatošanas tehnoloģijas radās pagājušā gadsimta piecdesmitajos gados un joprojām attīstās. Referāta mērķis ir aplūkot mākoņdatošanas jēdzienu, mākoņu veidus, mākoņdatošanas ieguvumus, kā arī ar tiem saistītās grūtības un riskus
INCREASING THE CULTIVATION AND DEVELOPMENT OF THE BEEF CATTLE FEED BASE OF THE KALNZIEDI FARM BY REDUCING GHG EMISSIONS
Get PDFThe 21st century has brought a number of challenges to the world that humanity has to face. Climate change is one of them and the world community must do everything it can to improve the current situation. Scientists have shown that the main cause of climate change is the increasing concentration of greenhouse gases (GHGs) in the atmosphere, driven by human economic activity. The environmental impact of the agricultural sector, in the form of increasing GHG emissions, is becoming more pronounced and farmers need in-depth knowledge of the greenhouse gas emissions from agricultural activities and their potential reduction on farms. This is all the more so as EU support for farms is planned to be linked to measures taken to reduce GHG emissions
LEGAL REGULATION OF THE MEDICAL TOURISM AS A TYPE OF ECONOMICAL ACTIVITY
No full textThe article is devoted to the problems of legal regulation of medical tourism as a type of economic activity. The definition of medical tourism, its structural components and peculiarities of legal regulation are given.Medical tourism is a type of tourist activity, characterized by the formation and sale of a tourist product. This product includes a package of general tourist services, as well as a package of medical services. There are such structural components of medical tourism: 1) curative tourism, providing medical and diagnostic services that can be provided only by entities that have the status of medical institutions; 2) rehabilitation and wellness tourism, which provides diagnostic, sanatorium-resort, preventive and other types of medical services that can be provided by medical institutions and other entities.The expediency of creating a single legal regime in the field of medical tourism is argued. This legal regime is necessary for effective protection of patients\u27 rights to life and health
ANXIETY AMONG SCHOOL-AGE CHILDREN IN WAR-AFFECTED AREAS IN UKRAINE AND WAYS TO REDUCE IT: PARENTS’ VIEWS
Get PDFThe Ukrainian-Latvian team of researchers are dedicated to commit their research to finding out parents’ views on whether school-age children experience anxiety in war-affected areas in Ukraine and ways to reduce it. The research also enables to identify the most common signs of anxiety. The data collection instrument includes a web-based questionnaire developed by researchers from Ukraine using Google Forms. All researchers are involved in sharing the developed web-based questionnaire via social media networks. The research sample includes 1346 parents of school-age children from all the parts of Ukraine, namely, Central, Eastern, Western, Northern, Southern Ukraine and Kyiv. Research findings demonstrate the urgent need to implement targeted psychological and pedagogical influences (the use of technologies, methods and techniques aimed at reducing the level of anxiety in school-aged children) in the educational process of general secondary schools, regardless of whether this process is carried out face-to-face, remotely or in a blended learning format. The conducted research makes it possible to substantiate the necessity of creating a web-based support system for educators to reduce anxiety among school-age children. The current research is carried out within the project “Web-based Support System for Educators to Reduce Children’s Anxiety in War-affected Areas” (Registration No GPK-07/2022)
THE ROLE OF EMOTIONS IN MUSIC EDUCATION: THEORETICAL INSIGHTS
Get PDFEmotional expression has been the focus of teachers and educational researchers, as it can result in an improvement in cognitive performance. In specific settings, personal and emotional experiences can provide a steppingstone to developmental and learning processes. Emotions significantly influence learner learning and play a crucial role in quality teaching, educational reform, and learner-teacher interaction. The inherent social and communicative nature of music would make group training an excellent tool for increasing the coordination of behaviour, affect, and mental states among children. This paper aims to explore the literature on various aspects of the concept of emotions in the context of music education with the main focus on opportunities for experiencing and expressing emotion in music education, learners\u27 positive emotion experiences in music education, teaching to generate positive emotion outcomes, and the benefits of a greater emphasis on the emotions in music education. The results of theoretical analysis indicate that music education has a particularly positive effect on identifying emotions, emotion regulation, emotion recognition, improved learning, and self-expression

ATTITUDE TOWARDS USING ICT IN LEARNING AND TEACHING MATHEMATICS
Get PDFThis study questions attitudes of students and mathematics teachers towards using ICT in state schools of Latvia. The author has been using Latvian education portal “uzdevumi.lv” in teaching of mathematics for several years and has observed a very wide acceptance of this learning tool both among children and teachers. On the other hand, there have been certain obstacles to apply this and other ICTs more widely. Other sites, such as “Geogebra” and “Brilliant” have been used by schools abroad. The author observes that the things that prevent schools from using such sites to a large degree depend not only from the availability of computers at school, but also from students and teachers attitudes towards using ICT in mathematics learning and teaching.
THE RELEVANCE OF TRANSFORMATIONAL LEADERSHIP IN THE CONTEXT OF THE COMPETENCE APPROACH IN PRE-SCHOOL
Get PDF. In the context of the ongoing changes in the education system of Latvia, the principles of learning approach in pre-school education are based on the competence-based approach, as well as the development of transformative skills. To successfully implement change, the need to develop teachers\u27 creativity, entrepreneurship, decision-making, organisational skills, teamwork, cooperation, sociability, risk-taking and assessment, openness to innovation, reflective thinking and leadership skills becomes essential. Today, it is important for every teacher to strive for professional development and to achieve individual and collective goals. Leadership skills include the ability to motivate others, good communication skills, positive thinking, delegation of responsibilities, creativity, reliability, responsibility, time management, influence, and decisiveness. Change can also be difficult to be accepted and even can become a reason for leaving a teaching job. Leaders who can accept contemporary challenges, communicate effectively with others, and facilitate the development of leadership skills in colleagues become important in every educational institution. The aim of this publication is to research and evaluate the scientific literature on the relevance of transformational leadership, highlighting the need for developing each teacher`s leadership skills
