Improving the Performance of Split Air Conditioner by Adding Nano Silver to the Compressor Oil

A high demand on the energy and power has brought scholars more attention to investigate new ways to reduce the energy consumption. The aim of this research is reducing the power consumption required for air conditioning to cool the room by adding nanomaterials to the compressor oil at a mass concentration of 0.15%. Two models of chambers with dimensions (2 x 2 x 2) meters were fabricated to represent the test section and connected to a 1ton compressor, one operating with natural oil as a standard basis for comparison, while the other one with Nano-oil prepared in the laboratory. The mass concentrations of 0.15% of silver nanoparticles (Ag) were prepared, and the stability of the nanoparticles was tested by direct observation for different time periods. The results indicated that the performance of the air conditioner was better with the addition of nanoparticles to the compressor oil compared to the pure oil in the compressor. Reducing energy consumption in the cooling system by (19%). Also, it was found that there is an increase in the cooling speed of the nanotechnology system by (6%)as well as in the efficiency of the Nano-oil system compared to the regular system by (13%). This study showed that the thermophysical properties of the cooling oil increased by increasing the weight ratios of solid nanoparticles by (12%).

Рhenomenon of states psychological self-regulation of teacher’s life activities

Based on the structural and system analysis, the article considers the need for self-regulation for teachers, substantiates and provides statistics on the negative psychophysical states of educators, which they acquire as a result of professional activity. One hundred teachers were interviewed in order to define the mastering level of their self-regulation and the need to educate teachers in the theory and practice of these aspects. Based on the data obtained, it is obvious that educators need education on this issue, and the level of assimilation of this information and skills still needs to be better. The necessity of developming the motivational system of self-regulation mastering by teachers through the following components of this motivation is substantiated in the article: it can be made through a condition of psychophysical health; because of the culturological need of educators and because of the need not to expose others, in particular children, according to the negatives of their emotional deviations; due to the need for pedagogical competence, which has the competence of the psychological spectrum, which determines the professional status; because of the need for the teacher to be a proactive person. Since teachers are mostly motivated to learn self-regulation mainly because of health and the effectiveness of such motivation is limited, we conclude that there should be several motivational areas, where each specialist will find what he needs. The article analyzes and systematizes theoretical principles of self-regulation of mental states of the personality in order to bring this information in an adaptive form for teachers. In this context, the periodization is made considering the research on self-regulation by scientists from foreign and national physiological and psychological schools. The meaningful information of theoretical bases of regulation is structured and systematized. The necessity of a regular system of education on the theory and practice of self-regulation is substantiated and in this perspective the article gives the basics of such education. In our publication the authors offer the term, forms of work and its content. Conclusions are made on improving the awareness of educators of the practical acquisition of knowledge, skills and abilities on the problem. Key words: self-regulation of personality mental states; motivation, mastery of self-regulation of mental states by the teacher; systematization of theoretical principles of self-regulation; basics of the teacher education project on self-regulation issues.

Non-communicable diseases’ risk factors in India: a review of the current situation

Non-communicable diseases (NCDs) are responsible for considerable morbidity and mortality, leading to a significant burden on the health care systems in developing countries like India. Despite heavy burden, there is no regular system of collection of good quality representative data on NCDs or their risk factors in India. The published review articles show the trends of risk factors, however only for one or few more risk factors, thereby rendering them non comprehensive. This paper examines the updated data and epidemiology of all the NCD risk factors, to provide the summary estimates of their prevalence at national level. A thorough knowledge on current status of risk factors is required to formulate the policies and programmes, so that the rising burden of NCDs can be tackled.

How is journalism defined in university handbooks? A conceptual analysis of students’ literature, examples of Russia and Belarus

New generations of journalists get involved in their professional activity after years of studies in journalism schools or universities. Handbooks supporting their studies are rarely in the focus of researchers. However, the definition of journalism presented in such books, are usually recognised as the basis of this profession’s identification. In this article, 501 Russian handbooks and 135 Belarusian student books published between 1991 and 2020 are analysed as a conceptual source of the definition of journalism. Concept-analysis (as a part of a cognitive linguistic approach) is applied to the data: each definition is interpreted as a set of ‘semantic quanta’ organised in the core-peripheric field (‘sphere’). This helps find an implicit ‘cognitive formula’ of journalism in post-Soviet countries journalism education and enables to identify its dynamics and stabilisation. In Russian handbooks, journalism is represented and defined as a regular system with institutional mechanisms (‘a news producing plant’), and in Belarusian student books, it is considered as individual art-literary writing (‘personal creativity’).

Flawed Progress: Criticisms of Residential Institutions for Child Migrants in Australia and Policy Responses, 1939–1945

The positive view of child migration held by UK Government officials in the inter-war period was not based on any regular system of inspections of the institutions in Australia to which children were sent. During the Second World War, UK Government officials became more of reported problems at several of these institutions, relating to standards of accommodation, management, care, training and after-care. This chapter traces the growing awareness of these problems and the UK Government’s response to them. Whilst policy-makers’ positive assumptions about child migration were challenged, and specific issues and institutions were known to require significant improvement, overall confidence in the value of child migration remained. Despite evidence of organisational failings in Australia, Australian welfare professionals were trusted to address these problems, and suggestions about the need for greater control from the United Kingdom were seen as a backward-looking attempt to limit the autonomy of Britain’s Dominions.

Rice Leaf Folder (Cnaphalocrosis medinalis) Infestation at Different Planting System and Varieties

The proliferation of pests is most influenced by the host (plants) and other environments including plant distance and humidity. Agriculture research and development departement has been released many varieties of rice but their resistance to pests and diseases on various developmental areas is different. The study aims to determine the population and attacks intensity of Rice Leaf Folder (Cnaphalocrosis medinalis) on farming rice jajar legowo ganda and regular systems (tegel). The research has been carried out on farmers fields in Buntulia Village, Duhiadaa District, Pohuwato Regency from June to October 2019. The study used a Split plot research design with four replications. The main plot is farming rice jajar legowo ganda and regular system. Sub plots are varieties: 1). Inpari 30, 2). Inpari 31, 3). Inpari 42, and 4). Situbagendit. Cnaphalocrosis Medinalis was observed when the plants age 5, 7, 9, and 11 week after planting (WAP) on 30 clumps per plot. The results showed Cnaphalocrosis medinalis attacking on all varieties in both systems. However, Cnaphalocrosis medinalis attacks on the farming rice jajar legowo ganda (average 7.96 %) has as lower as than regular system (av. 3.95 %)) on the observations per weeks. The intensity of Cnaphalocrosis medinalis attacks on Inpari 31 (av. 5.56 %) as lower as than Situbagendit (av. 13.43 %). The result showed highest populations Cnaphalocrosis medinalis was found on regular system (av. 9.35 h / c) lowest Cnaphalocrosis medinalis populations was on the rice farming jajar legowo ganda (av. 7.96 h / c). Highest populations of Cnaphalocrosis medinalis was found on Situbagendit variety and Inpari 30 variety has lowest populations. Cnaphalocrosis medinalis attack intensity, generally increasing with rice age, the population density was relatively decreased because control doing.Keywords: rice leaf folder, planting system, varieties.

PERBANDINGAN PRESTASI BELAJAR SISWA SISTEM FULL DAY SCHOOL DAN SISTEM REGULER KELAS IV SEKOLAH DASAR TAHUN AJARAN 2019/2020 DI KECAMATAN KEBUMEN

The education system in Indonesia is divided into two types, namely the education full-day school system and the regular system. These two systems have differences in the length of study time, the emotional level of students, and the fatigue of students. The fatigue will greatly affect students in terms of learning which will also affect the level of student achievement during school. The study aimed to explain the differences between full-day school system and regular system on student learning achievement to fourth grade of elementary school. It used comparative quantitative research methods. Data collection techniques were observation and tests. Data analysis used test Independent Sample T-test. The result of the research indicated that there were differences between full-day school system and regular system on student learning achievement to fourth grade of elementary school in Kebumen sub-districts in academic year of 2019/2020. The Sig value on the independent sample t-test was 0.034. It meant that Sig value was 0.000 <0.05 (level 5%) thus it rejected H0. The averages of student learning achievement of fourth grade were 8.5867 in regular system and 8.3685 in full-day school system.

Monotonicity and Weighted Prenucleoli: A Characterization Without Consistency

A solution on a set of transferable utility (TU) games satisfies strong aggregate monotonicity (SAM) if every player can improve when the grand coalition becomes richer. It satisfies equal surplus division (ESD) if the solution allows the players to improve equally. We show that the set of weight systems generating weighted prenucleoli that satisfy SAM is open, which implies that for weight systems close enough to any regular system, the weighted prenucleolus satisfies SAM. We also provide a necessary condition for SAM for symmetrically weighted nucleoli. Moreover, we show that the per capita nucleolus on balanced games is characterized by single-valuedness (SIVA), translation covariance (TCOV) and scale covariance (SCOV), and equal adjusted surplus division (EASD), a property that is comparable to but stronger than ESD. These properties together with ESD characterize the per capita prenucleolus on larger sets of TU games. EASD and ESD can be transformed to independence of (adjusted) proportional shifting, and these properties may be generalized for arbitrary weight systems p to I(A)Sp. We show that the p-weighted prenucleolus on the set of balanced TU games is characterized by SIVA, TCOV, SCOV, and IASp and on larger sets by additionally requiring ISp.

Shuttling between Diplomacy and Expertise in Developing Methods of Work

This chapter analyzes the influence of political factors in providing both freedom for diverse approaches to implementation of methods of work and explicit or implicit limits determining the operationalization of mandates. The chapter focuses on the challenges associated with the public nature of the activities of Special Procedures and the tendency of mandate holders to perform different roles, which may not be always compatible. Mandate holders have developed methods of work that have consolidated the Special Procedures as direct interlocutors with governments, intergovernmental, and non-governmental organizations and other stakeholders. Contemporary Special Procedures constitute a regular system of monitoring state behavior through the treatment of alleged cases of human rights violations under their competence; visits on the grounds; analytical studies of specific issues influencing the situation of human rights in a concerned territory or worldwide; and the generation of an enormous volume of data on recorded violations over time. They have shed light, clarified, and at times contributed to the applicable international and national legal frameworks. They have played an activist role beyond the realm of individual cases, using their expertise to mediate or intervene in legal and political disagreements within and outside formal mechanisms of dispute settlement. They raise awareness of, highlight, and promote best practices to improve the situation of human rights around the globe, as well as the circumstances that propitiate human rights violations, including their link with the development and security agenda.
