The study was carried out with the aim of determining the mineral composition of the soil from the north-eastern region in Al-Hasakah governorate in Syria and its effect on some physical and chemical soil properties. Where five sections were excavated and three samples of dirt were taken from each section according to horizons, The results of the mineral composition study showed a group of primary metals and the highest percentage of calcite in the studied soils, Followed by quartz metal in terms of spread in the studied soils, but the potassium feldspar (Othoclaz) was less than calcite and quartz in the studied soils, while found only pyroxene in the soil of the fourth and fifth sectors where the rock basalt mother, while found Baligorskit metal and a small percentage in all types The clay minerals were found to be high in the fourth sector and less on the horizon A1 for the other sectors. There was no A0 in the horizon for the first two sectors (Al-Hasakah) and the second (Qamishli). Mica (often alkaline), kaolinite and chlorite were found to be lower in thickness than in all soil samples studied.                  The results of the physical study showed that most of the soils have a clay texture, with the lowest percentage of mud and hysteroscopic in the surface depth of Qamishli soil (Tal Maarouf) (41.00) and (5.06)%, respectively, in Tin Tin and Shakhala, in the third depth of the Malikiyah soil (Deir Tigris), and the bulk density values ​​ranged between (1.19-1.33) g / cm3, and the real density values ​​ranged from (2.62-2.75) g / cm3, and was accompanied by a variation in the values ​​of the total porosity, as its value ranged between (50.15--54.58)%. The chemical and fertility results showed that the degree of (pH) soil is moderate on the surface horizon of al-kamshli soil, reaching (7.71), and the average alkalinity becomes slightly more than (8.00), and the soil content of the exchanged cations ranged from medium to high, ranging between (32.24 and 45.32). m.m / 100g soil, and the calcium cation occupies the first place on the adsorption complex, followed by magnesium. The content of the studied soils from the organic matter in the first depth is considered low because its value ranges between (00.5 - 01.0)%. The total calcium carbonate percentage ranged between the lowest value (21.63%) in the Al-Malikiyah soil (Deir Djla), and the highest value (31.91%) in Qamishli (Tal Maouf).   By studying the kinetics of potassium, it was found that the ARKe values ranged between (0.0092 and 0.183) (mol / liter) 1/2, where the highest value of ionic activity was recorded in Malikiyah soil (0.0183) (mol / liter) 1/2 and the lowest value of ionic activity was recorded in Qamishli soil. 0.0092 (mol / liter) 1/2. The values of K∆ for the studied soils ranged from (0.3595 - 0.885) centimole. Kg-1, where the values of the potassium voltage regulation values of the studied soils ranged between (33.751- 60.314) [cmol kg-1] / (M L-1) 0. 5]. That the values of the Capon modulus ranged between (0.867 - 1.713) liters to mol -1.

The Bodo of the North Eastern region of India have their own kinship system to maintain social relationship since ancient periods. Kinship is the expression of social relationship. Kinship may be defined as connection or relationships between persons based on marriage or blood. In each and every society of the world, social relationship is considered to be the more important than the biological bond. The relationship is not socially recognized, it fall outside the realm of kinship. Since kinship is considered as universal, it plays a vital role in the socialization of individuals and the maintenance of social cohesion of the group. Thus, kinship is considered to be the study of the sum total of these relations. The kinship of the Bodo is bilateral. The kin related through the father is known as Bahagi in Bodo whereas the kin to the mother is called Kurma. The nature of social relationships, the kinship terms, kinship behaviours and prescriptive and proscriptive rules are the important themes of the present study.

Background: Malaria is endemic in various parts of India particularly in the North- Eastern states with Plasmodium falciparum-the most prevalent human malaria parasite. Plantderived compounds have always received tremendous importance in the area of drug discovery and development and scientific study of traditional medicinal plants are of great importance to mankind. Objective: The present work deals with the computational study of some antimalarial compounds obtained from a few medicinal plants used by the tribal inhabitants of the North-Eastern region of India for treating malaria. Methods: In silico methodologies were performed to study the ligand-receptor interactions. Target was identified based on the pharmacophore mapping approach. A total of 18 plant-derived compounds were investigated in order to estimate the binding energies of the compounds with their drug target through molecular docking using Autodock 4.2. ADMET filtering for determining the pharmacokinetic properties of the compounds was done using Mobyle@RPBS server. Subsequent Quantitative-Structure Activity Relationship analysis for bioactivity prediction (IC50) of the compounds was done using Easy QSAR 1.0. Results: The docking result identified Salannin to be the most potent Plasmepsin II inhibitor while the QSAR analysis identified Lupeol to have the least IC50 value. Most of the compounds have passed the ADME/Tox filtration. Conclusion: Salannin and Lupeol were found to be the most potent antimalarial compounds that can act as successful inhibitors against Plasmepsin II of P. falciparum. The compounds Salannin and Lupeol are found in Azadirachta indica and Swertia chirata plants respectively, abundantly available in the North-Eastern region of India and used by many inhabiting tribes for the treatment of malaria and its symptoms.

The production levels of agriculture have remained low in eastern region of India mainly due to lack of location-specific production technologies, natural calamities like floods, water logging, drought, inadequate timely supply of critical inputs and social constraints. Bihar is one of the important agrarian states of Eastern India. The crop yields are low and almost stagnating in Bihar compared to the north-western and other parts of the country. To improve the productivity in this region mechanization of farms is of critical importance. The farm power availability in Bihar in 2017 is 2.80 kW/ha and is more than the national average of 2.03 kW/ha. Still there are 14 districts in Bihar which is below national average. The number of marginal farmers has increased from 84.18 to 91.21 during 2014-17, an increase of 7.03 percent. Increase in Small and fragmented land will further hindrance the farm mechanization process. The present study was conducted to understand dynamics of farm power availability in Bihar, so as to take substantial measures for improved mechanization and in turn crop productivity in the region.

The Sunamganj district is covered by major Haor systems in the north-eastern region of Bangladesh. Flash flood is the most commonly occurring water related disaster in the Haor areas. During the flash flood it is very common that people lost their primary agricultural productions which are the only source of their livelihood. The present study focuses on the effects of 2017 early flash flooding on rice and fish production of Sunamganj Haor areas. The flood caused enormous damage to agriculture such as rice especially Boro rice and fish production on which the Haor dwellers rely upon for their livelihood. The total affected land of Boro rice cultivation in Haors of Sunamganj was 149,224 hectare and the total amount of damaged rice was 393,855 metric ton (MT). The total number of affected farmers was 315,084. The early flash flood also affects the quality of Haor water which caused the death of fishes. The total amount of damaged fish was 49.75 MT and the loss was 158.70 lakh taka. The total number of affected fishermen was 44,445. This findings could be very useful for the environmental scientists to predict the probable future effects on agricultural production due to early flash flood events in Sunamganj Haors areas.

The accelerated urbanisation process that Brazil has gone through in the last 50 years has given rise to daunting challenges for public managers, especially in terms of local public policy management for the building of “healthy cities”. In Sobral, a municipality of 173,000 inhabitants in Ceará in the North-eastern region of Brazil, a number of municipal policies were initiated beginning in 1997, many in partnership with the federal and state governments. They were inspired by the vision of a healthy and equitable city and were marked by strategic planning and the implementation of intersectoral projects. This article lays out some of the actions and their results, including an increase in the public supply of drinking water from 65% to 97% of households; an increase in sewage networks from 7% to 65%; an increase in public refuse collection from 42% to 90%; the expansion of green areas; the construction of nine kilometres of bicycle paths; the universalisation of integral health care through the Family Health Strategy through a network with specialised out-patient and hospital services; and a 148% increase in the number of children enrolled in primary school. These initiatives also resulted in the improvement of quality of life indicators, including a reduction in infant mortality from 61.4 to 19.0 per thousand live births, a drop in the mortality rate from traffic accidents from 33.40 per 100,000 inhabitants in 2001 to 15.25 in 2003; and a jump in literacy rates among children in the first cycle of primary school from 40 to 90.7%. In the present article, the authors describe some of the successful strategies and projects initiated between 1997 and 2003, and discuss how this experience could be reproduced in other communities across Brazil and around the world.
