The experimental data presented in the article show that in the North-Eastern sector of the Middle Caspian sea in the area of Peschanomyssky uplift there is a disturbance of currents caused by the interaction of the cyclonic cycle with the southern slope of the uplift. As a result of this interaction, the waters of the cyclonic cycle are divided into branches – the lower and upper. The lower bottom branch is thrown by the uplift in the South-Western direction, where at the Cape of the uplift it collides with the waters flowing down the bottom of the South-Buzachinsky deflection in the South-Eastern direction, and the upper branch, consisting of near-surface and intermediate cold waters, is pushed up and passes through the uplift. As a result of the rise of cold water in the surface layer formed upwelling, which extends to the entire North-Eastern region of the sea.

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.

To the North Eastern Region (NER) of India, lie the unexplored states of the Indian Union. This region holds a unique place in the federal structure of India. This article attempts to scrutinise the diversity of NER, along with the potential of the National Cadet Corps (NCC) as a medium to change, uplift and assimilate it with pan India. The article aims to comprehend how NER can accommodate the regional identities and cultural affinities with Indian mainstream identity through the intervention of NCC at college and university level. The methodology of this article is based on secondary resources such as published books, journals, web pages, reports, newspapers and online sources. The article is analytical and descriptive in nature based on thematic approach.

A taxonomic revision of the Nystiellidae from Brazil, including samples from the Rio Grande Rise, South Atlantic, was performed based on shell morphology. Five genera and 17 species were recognized. For the richest genus,Eccliseogyra, the three species previously recorded from Brazil were revised:E. brasiliensisandE. maracatu, previously known only from their respective type series, were re-examined. Newly available material ofE. maracatuexpanded the known geographic range of this species to off south-east Brazil.Eccliseogyra nitidais now recorded from north-eastern to south-eastern Brazil, as well as from the Rio Grande Rise. Three species ofEccliseogyraare newly recorded from the South Atlantic:E. monnioti, previously known from the north-eastern Atlantic, occurs off eastern Brazil and on the Rio Grande Rise; its protoconch is described for the first time, confirming its family allocation.Eccliseogyra pyrrhiasoccurs off eastern Brazil and on the Rio Grande Rise, andE. folinioff eastern Brazil. The genusIphitusis newly recorded from the South Atlantic.Iphitus robertsiwas found off northern Brazil, although the shells show some differences from the type material, with less-pronounced spiral keels. Additional new finds showed thatIphitus cancellatusranges from eastern Brazil to the Rio Grande Rise, and Iphitusnotiossp. nov. is restricted to the Rio Grande Rise.Narrimania, previously recorded from Brazil based on dubious records, is confirmed, including the only two living species described for the genus:N. azelotes, previously only known from the type locality in Florida, andN. concinna, previously known from the Mediterranean. A third species,Narrimania raquelaesp. nov. is described from eastern Brazil, diagnosed by its numerous and thinner cancellate sculpture. To the three species ofOpaliopsispreviously known from Brazil, a fourth species,O. arnaldoisp. nov., is added from eastern Brazil, and diagnosed by its very thin spiral sculpture, absence of a varix, and thinner microscopic parallel axial striae.Papuliscala nordestina, originally described from north-east Brazil, is recorded off eastern Brazil and synonymized withP. elongata, a species previously known only from the North Atlantic.

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.

In 2012, in the village Davidovac situated in south Serbia, 9.5 km south-west from Vranje, archaeological investigations were conducted on the site Crkviste. The remains of the smaller bronze-age settlement were discovered, above which a late antique horizon was later formed. Apart from modest remains of a bronze-age house and pits, a late antique necropolis was also excavated, of which two vaulted tombs and nine graves were inspected during this campaign. During the excavation of the northern sector of the site Davidovac-Crkviste the north-eastern periphery of the necropolis is detected. Graves 1-3, 5 and 6 are situated on the north?eastern borderline of necropolis, while the position of the tombs and the remaining four graves (4, 7-9) in their vicinity point that the necropolis was further spreading to the west and to the south?west, occupying the mount on which the church of St. George and modern graveyard are situated nowadays. All graves are oriented in the direction SW-NE, with the deviance between 3? and 17?, in four cases toward the south and in seven cases toward the north, while the largest part of those deviations is between 3? and 8?. Few small finds from the layer above the graves can in some way enable the determination of their dating. Those are two roman coins, one from the reign of emperor Valens (364-378), as well as the fibula of the type Viminacium-Novae which is chronologically tied to a longer period from the middle of the 5th to the middle of the 6th century, although there are some geographically close analogies dated to the end of the 4th or the beginning of the 5th century. Analogies for the tombs from Davidovac can be found on numerous sites, like in Sirmium as well as in Macvanska Mitrovica, where they are dated to the 4th-5th century. Similar situation was detected in Viminacium, former capital of the roman province of Upper Moesia. In ancient Naissus, on the site of Jagodin Mala, simple rectangular tombs were distributed in rows, while the complex painted tombs with Christian motifs were also found and dated by the coins to the period from the 4th to the 6th century. Also, in Kolovrat near Prijepolje simple vaulted tombs with walled dromos were excavated. During the excavations on the nearby site Davidovac-Gradiste, 39 graves of type Mala Kopasnica-Sase dated to the 2nd-3rd century were found, as well as 67 cist graves, which were dated by the coins of Constantius II, jewellery and buckles to the second half of the 4th or the first half of the 5th century. Based on all above mentioned it can be concluded that during the period from the 2nd to the 6th century in this area existed a roman and late antique settlement and several necropolises, formed along an important ancient road Via militaris, traced at the length of over 130 m in the direction NE-SW. Data gained with the anthropological analyses of 10 skeletons from the site Davidovac-Crkviste don't give enough information for a conclusion about the paleo-demographical structure of the population that lived here during late antiquity. Important results about the paleo-pathological changes, which do not occur often on archaeological sites, as well as the clearer picture about this population in total, will be acquired after the osteological material from the site Davidovac-Gradiste is statistically analysed.
