The key objective of this study is to examine the livelihood practices and strategies adopted by the Scheduled Tribe (ST) population of the Palasbari Revenue circle, Assam, India. For empirical analysis, 132 households were surveyed from 6 areas dominated by the ST population, namely Kallapara N.C. (Satargaon), Jimirigaon, Rani Khamar, Chouthala, Jupangbari, and Kochpara, which aggregates to 553 sample populations. It was surveyed by stratified random sampling method from January to March 2020. The results show that livelihood diversification, agricultural intensification and temporal migration are three of the major strategies adopted by the population to meet their needs.

The Empirical Analysis

AbstractThe aim of the study is to present the phenomenon of population migration and migration policy as part of the state’s economic policy based on the example of OECD (Organization for Economic Cooperation and Development) countries, with particular emphasis on the area of migration policy, which is border control and related illegal migration. The temporal scope of the empirical analysis covers the period 1990-2016. The article consists of four main parts. The discussion began with a presentation of the balance of migration, the scale and dynamics of population immigration in OECD countries. Furthermore, the significance, areas and process of shaping migration policy as a part of the economic policy of the country are presented. Then, it focused on the migration policy in the area of border control in OECD countries. The discussion was crowned with the conclusions that followed.

And Migration

After experimetnal damage to the retina with a variety of procedures Müller cell hypertrophy and migration occurs. According to Kuwabara and others the reactive process in these injuries is evidenced by a marked increase in amount of glycogen in the Müller cells. These cells were considered originally supporting elements with fiber processes extending throughout the retina from inner limiting membrane to external limiting membrane, but are known now to have high lactic acid dehydrogenase activity and the ability to synthesize glycogen. Since the periodic acid-chromic acid-silver methenamine technique was shown to demonstrate glycogen at the electron microscope level, it was selected to react with glycogen in the fine processes of the Müller cell that ramify among the neural elements in various layers of the retina and demarcate these cells cytologically. The Rhesus monkey was chosen as an example of a well vascularized retina and the rabbit as an example of a avascular retina to explore the possibilities of the technique.

And Migration

As was demonstrated by the present authors that atomic structure of simple crystal can be photographed by the conventional 100 kV electron microscope adjusted at “aberration free focus (AFF)” condition. In order to operate the microscope at AFF condition effectively, highly stabilized electron beams with small energy spread and small beam divergence are necessary. In the present observation, a 120 kV electron microscope with LaB6 electron gun was used. The most of the images were taken with the direct electron optical magnification of 1.3 million times and then magnified photographically.1. Twist boundary of ZnSFig. 1 is the image of wurtzite single crystal with twist boundary grown on the surface of zinc crystal by the reaction of sulphur vapour of 1540 Torr at 500°C. Crystal surface is parallel to (00.1) plane and electron beam is incident along the axis normal to the crystal surface. In the twist boundary there is a dislocation net work between two perfect crystals with a certain rotation angle.
