Since 1979, the International Union of Pure and Applied Chemistry (IUPAC) Commission V.8 on Solubility Data has published over 70 compilations of evaluated data on the solubility of gases in liquids, liquids in liquids, and solids in liquids. These volumes represent one of the largest collections of chemical property data ever produced and are the result of work of scientists throughout the world. In 1998, IUPAC signed an agreement with the National Institute of Standards and Technology (NIST) to continue the series by replacing the monographs by articles in the Journal of Physical and Chemical Reference Data. Five data compilations have already been published in the Journal, and many more are under way. Recently, IUPAC and NIST have concluded another agreement about computerizing all previously published IUPAC solubility data. In this paper, we describe in detail the computerization of IUPAC solubility data, with some emphasis on harmonizing data published over a long time period. We describe the anticipated query paths that will be supported. We also discuss some of the driving forces for making these and other data resources available over the World Wide Web.

The most preferred method for preserving food or related products for a long time period is drying. In various countries of the world, the utilization of solar thermal systems in the field of agricultural for conserving fruits, vegetables, coffee and other related crops has revealed to be economical, practical, and environmental friendly. Solar heating systems to dry food and other crops can improve the quality of the product, while reducing wasted produce. This paper deals with development of solar cum eclectically operated food dryer. The fabrication of hybrid dryer is carried out which will be used for the drying process. The amounts of solar radiations are collected through transparent sheet or glass and they are entered in to dryer. Then, amount of heat will get generated in dryer and it will be circulated through fan in dryer itself which will be suitable for drying purpose. The experimentation is also carried out on two foods related to drying process at normal temperature and using this dryer obtained temperature. After experimentation it has been observed that there is difference in temperature at outside the dryer and inside the dryer. The temperature generated inside the dryer is sufficient for drying purpose. So, the developed food dryer can be used for drying the foods as per requirement.

Preservation of the main physical and chemical properties of vitrified high-level waste over a long-time period under the influence of heavy radiation exposure is considered as an essential criterion for its quality assessment used to demonstrate the safety of intermediate storage under controlled conditions and subsequent final disposal of the waste. Earlier calculations covering a time period of up to 104 years allowed to identify the maximum beta- and gamma-radiation induced dose loads for borosilicate glass (BSS) of a basic composition specifically designed to vitrify liquid HLW from ODC MCC [1]. This study evaluates potential feasibility of applying an accelerated proton beam to simulate radiation damage according to the type of beta-gamma effects produced on the BSS and investigates the consequences of such effects on its properties which is seen as a distinctive feature of this research.

Abstract. The analysis of the VLF signals radiated by ground transmitters and received on board of the French DEMETER satellite, reveals a drop of the signals (scattering spot) connected with the occurrence of large earthquakes. The extension of the "scattering spots" zone is large enough (1000–5000 km) and, probably, it increases with the magnitude of the "relative" earthquake. A possible model to explain the phenomenology, based on the acoustic gravity waves and the ionosphere turbulence, is proposed. The method of diagnostics applied to this study has the advantage to be a global one due to the world wide location of the powerful VLF transmitters and of the satellite reception. However, a specific disadvantage exists because the method requires rather a long time period of analysis due to the large longitudinal displacements among the successive satellite orbits. At the moment, at least, one month seems to be necessary.

The phenomenon of economic growth is studied by economists and statisticians in various aspects for a long time. Economic theory is devoted to assessing factors of growth in the tradition of R. Solow, R. Barrow, W. Easterly and others. During the last quarter of the century, however, the institutionalists, namely D. North, D. Wallis, B. Weingast as well as D. Acemoglu and J. Robinson, have shown the complexity of the problem of development on the part of socioeconomic and political institutions. As a result, solving the problem of how economic growth affects inequality between countries has proved extremely difficult. The modern world is very diverse in terms of development level, and the article offers a new approach to the formation of the idea of stylized facts using cluster analysis. The existing statistics allows to estimate on a unified basis the level of GDP production by 174 countries of the world for 1992—2016. The article presents a structured picture of the world: the distribution of countries in seven clusters, different in levels of development. During the period under review, there was a strong per capita GDP growth in PPP in the middle of the distribution, poverty in various countries declined markedly. At the same time, in 1992—2016, the difference increased not only between rich and poor groups of countries, but also between clusters.

Cruel and inhumane acts that harm human life and health, as well as humiliate the dignity, are prohibited in most countries of the world, and Russia is no exception in this issue. The article presents an analysis of the institution of responsibility for torture in the Russian Federation. The author comes to the conclusion that the current criminal law of Russia superficially and fragmentally regulates liability for torture, in connection with which the author formulated the proposals to define such act as an independent crime. In the frame of modern globalization, the world community pays special attention to the protection of human rights, in connection with which large-scale international standards have been created a long time ago. The Universal Declaration of Human Rights and other international acts enshrine prohibitions of cruel and inhumane acts that harm human life and health, as well as degrade the dignity.Considering the historical experience of the past, these standards focus on the prohibition of any kind of torture, regardless of the purpose of their implementation.

ABSTRACTShare of Indonesia's export value of natural rubber in the international market is almost always below Thailand, which is one of the competiting countries. The others countries began to become a threat to Indonesia because their exports share of natural rubber showed an increasing. This indicates that there is intense competition in the international market. As a country with the largest plantation area in the world, Indonesia should be superior. But this can be an opportunity to be able to compete in the world market so it is important to be managed more deeply so that it can create competitive advantages that can increase competitiveness. This study aims to determine the position of the competitiveness of natural rubber exports for the three countries of ITRC in the international market. The analytical method used is dynamic RCA. The results showed that all products of natural rubber coded HS 400110, 400121, 400122, 400129 and 400130 were experiencing a decline in growth in the export share of the three countries of ITRC : Indonesia, Thailand and Malaysia, but the market demand conditions for these products were declining in that time period.

From an economic and strategic perspective, the Strait of Malacca is one of the most important shipping lanes in the world. It has always been a strategic maritime route that benefitted kingdoms of Tiriwizara, Majapahit, Malakka, Pagan, Hantawaddy and Konbong Kingdoms of Myanmar. Thanks to the long borderland, China and Burma have always engaged in trade and diplomatic relation. Burma, presently called Myanmar, is an important country from the perspective of geo-politics in the region, but never has the situation of 8 million Muslims in this country been worse. Muslims have been living in Myanmar for a long time. The previous Buddhist rulers of the country and the British administration that followed provided rights of citizenship to them without discrimination. In the light of these welcoming circumstances, Muslims were happy to contribute to the nation by joining the army, the police force, government institutions in areas such as health care, education, trade, business, agriculture as well as in politics and as legislators in the parliament of Myanmar. Nevertheless, their unfortunate history began when the military came into power in 1962. All the rights and responsibilities they had enjoyed over the years became restricted. Discrimination policies were applied in every segment of national institutions, thereby threatening their citizenship rights. The discrimination continued to the extent that their racial status as one of the 145 ethnic groups of Myanmar was removed. Consequently, frequent riots, afflictions, and violence against Muslim minorities became the norm, rendering peaceful coexistence between Muslim and Buddhists difficult. The objective of this paper is to research the historical existence and identification of Muslims in Myanmar. Findings of this work will touch upon a theory of peaceful coexistence between Muslims and Buddhists in Myanmar. Keywords Islam, Muslim, identity, rights, discrimination, peace, coexistence. Abstrak Dari perspektif ekonomi dan strategik, Selat Melaka adalah salah satu laluan perkapalan yang paling penting di dunia. Ia sentiasa menjadi laluan maritim strategik yang memberi manfaat kepada kerajaan-kerajaan kerajaan Tiriwizara, Majapahit, Malakka, Pagan, Hantawaddy dan Kerajaan Konbong Myanmar. Disebabkan sempadan yang panjang, China dan Burma sentiasa terlibat dalam perdagangan dan hubungan diplomatik. Burma, yang kini dipanggil Myanmar, adalah negara penting dari perspektif geo-politik di rantau ini, tetapi 8 juta umat Islam di negara ini tidak pernah mengalami keadaan yang buruk. Umat Islam telah tinggal di Myanmar sejak beberapa ribu tahun yang lalu. Para pemimpin Buddha terdahulu dan juga pentadbiran British memberi hak kewarganegaraan kepada umat Islam tanpa diskriminasi. Keadaan ini menyebabkan umat Islam dengan rela hati  tampil memberi sokongan kepada negara dengan menyertai tentera, pasukan polis, terlibat dalam institusi kerajaan dalam bidang kesihatan, pendidikan, perdagangan, perniagaan, pertanian, politik dan penggubal undang-undang dalam parlimen Myanmar. Walau bagaimanapun, sejarah buruk bermula apabila golongan tentera berkuasa pada tahun 1962. Semua hak keistimewaan yang mereka nikmati selama bertahun-tahun menjadi terhad. Dasar diskriminasi telah digunakan pada setiap segmen institusi nasional dan telah mengancam hak kewarganegaraan mereka. Diskriminasi ini berterusan sehingga status mereka sebagai salah satu daripada 145 kaum Myanmar dihapuskan. Akibatnya, kerusuhan, kesengsaraan, dan kekerasan yang sering berlaku terhadap kaum minoriti Muslim menjadi norma dimana tidak mungkin akan wujud kesefahaman antara Islam dan Buddha. Objektif makalah ini adalah untuk menyelidik kewujudan sejarah dan identifikasi umat Islam di Myanmar. Hasil kajian akan menyentuh teori kedamaian antara umat Islam dan Buddha di Myanmar. Kata Kunci: Islam, Muslim, identiti, Hak, diskriminasi, kemanan, coexisten
