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.

The present paper is an attempt to analyse the spatial patterns of migration, variations in the level of socio-economic development and the relationship between total migration (dependent variable) and selected variables of development (independent variables) among the states of India. The entire research work is based on secondary sources of data, collected from Census of India publications (2011), Migration Table – D Series, Handbook of Statistics of Indian States, Primary Census Abstract of India and Basic Road Statistics of India. The boundary of a state has been taken as the smallest unit of the study. The present study reveals that, from the southern part of the country, the level of migration changes rapidly from high to low grade towards the north. On the other hand, the states lying in the western and eastern part experienced medium to high level of migration in comparison to the north-eastern states having a low level of migration in India. The level of development is high or medium in northern, western and southern states in comparison to the states, lying in the eastern and north-eastern parts of the country.

The relationship between the increase of the sea surface temperature observed off the Galician coast and the appearance of a tropical poikilotherm species Argonauta argo in these coasts is discussed. This is the first record of Argonautaargo in the north-west Iberian Peninsula. A female of this species was captured alive near the surface at dusk on 22 December 2000 in the Ria de Aldán (42°15′N–08°48′W). The specimen, a mature female of 70 mm mantle length and 96 mm shell diameter, died 36 hours after introduction in the tank.

Studies of associations in West Africa have tended to focus upon the development of new development-related institutional forms. Other, so-called traditional, cultural groupings have tended to be ignored. This article points to transformations and changes in the masquerade society of the north-eastern Yoruba town of Ìkòlé and considers the continuing development of the masquerade society as an association. Changes in the masquerade society are being strongly promoted by younger men as a way to establish masquerade as a resource, promoting Ìkòlé's cultural identity. They are aided and funded by groups of elite citizens who are not necessarily resident in Ìkòlé. The article examines the relations between the various groups involved in masquerade, as well as the relationship between those often elite town members who support masquerades and Pentecostal Christian groups which would happily see their demise.

Salmonellosis is an acute intestinal infectious disease that belongs to the group of zoonoses that cause acute toxic infections in humans through the consumption of products of animal or plant origin contaminated with bacteria of the genus Salmonella spp. Salmonellosis is registered in all countries of the world, and our state is no exception. The aim of the research. Monitor salmonellosis pathogens in Ukrainian poultry farms and, on the basis of the obtained data, establish the relationship between avian and human diseases for salmonellosis. Materials and methods. The research was conducted in poultry farms in the North-Eastern region of Ukraine. Test systems from R-biopharm-Compact Dry SL and RIDA®STAMP SL were used for rapid diagnosis of bacterial microflora. To establish the salmonella serotype, the Spectate® salmonella test system was used, which is based on the use of latex strips coated with special antibodies to the corresponding serogroups of Salmonella A, B, C, D. Microbiological examination was performed washing from the walls, floor, eggshell, Brooder's cabinets and pathogens heart, liver, gallbladder of the dead bird. The relationship between isolated salmonella serovars from poultry was compared with salmonella isolated from humans according to the reporting form No. 40 “Zdorov”. Results. Various salmonella serovars were isolated from experimental farms of Ukraine, namely: Serovars such as S. Gallinarum–pullorum – 7.9 %, S. Enteritidis – 6.5 % were isolated from the meat and egg direction. From the meat direction, the following are: S. Tiphimurium – 12.5 %, S. Arizona – 6.0 %, S. Enteritidis – 3.5 %. From the breeding direction were also isolated from adult birds and hatching eggs in large quantities – S. Gallinarum–pullorum – 19.0 %, S. Tiphimurium – 17.8 %, S. Enteritidis – 10.1 %. The following species were separately isolated from the premises of the same farms in percentage terms: S. London – 1.7 %, S. Infantis – 1.5 % S. Bredeney – 1.4 %, S. Tsioque – 1.4 %, S Jawa – 1.2 %, S. Montevideo – 1.1 %, and 1 % each isolated S. Kentyki, S. Abony and S. Oxford. Pathogens of paratyphoid diseases were isolated from poultry and poultry products (S. Gallinarum–pullorum, S. Enteritidis, S. Tiphimurium) for the entire study period from 2016 to 2020 inclusive. Comparing the obtained data from state institutions of humane medicine, it should be noted that there was a tendency for the spread of salmonellosis among people associated with the consumption of poultry products. Conclusions. The obtained results indicate that salmonella infection is quite common among a number of poultry farms of different technological direction. In particular, bacteria of the genus Salmonella were isolated from meat, eggs and birds of different ages from the studied poultry houses in the North-Eastern region of Ukraine.  As a result of monitoring of salmonellosis in Ukraine over the past five years, fluctuations in the incidence of salmonellosis among people ranged from a maximum of 74 % (2018) to a minimum of 30.1 % (2020), and for two years, there has been a reduction in cases due to the introduction of new international requirements and standards for product quality control at all stages of production of the Hazard Analysis and Critical Control Point (HACCP) system.

Copper toxicity in the ecosystems have becomes a global concern in recent times; therefore, there is need to curtail the increment of copper concentration within the environment. In this study, a total of 67 ground water samples were collected from the premises of Delta State Polytechnic, Ozoro, at a depth of 90 cm. The water samples were collected during the peak of the rainy season (September 2019); when the water table of the study area was very high, close to the soil surface. Copper concentration of all the water samples collected was measured using the Atomic Absorption Spectrophotometer (AAS). The results showed that copper concentration in the study ranged between 1.01 mg/L and 2.105 mg/L. The spatial distribution of the copper concentration within the study area was determined using Geostatistical tool. Variation map developed from the results showed that the copper concentration does not spread uniformly across the study area. High copper concentration was generally recorded at the North Eastern and central parts of the school; while low copper concentration was recorded at the South Eastern part of the school. Furthermore, the results strongly showed that waste dump potentially affects the copper concentration of the ground water within the study area. This study results advocated the need for proper waste disposal with the polytechnic environment, and the adequate treatment of the groundwater before human consumption.

This article is based on the results of a project on social change in the Early and Middle Bronze Age in the north-eastern Netherlands, which ended in 1991. Although the project originally focused on the possible development of social stratification, here, the emphasis will be on the relationship between burial ritual and social change in general. Before embarking on the main argument, it should be understood that the link between burial ritual and social change by no means implies the view that burial ritual reflects all social changes which take place within a society, nor that the changes observed in the burial ritual are essential to an understanding of the society concerned. The burial ritual offers us no more than an opportunity to study past social changes. The resulting interpretations should be supported and tested by other expressions of material culture, such as those concerning economy and settlement patterns.

Having always been much interested in any evidence that might throw light on the relationship of early man to the glacial drifts, I have for twenty-five years or more watched the various beds of gravel that occur above, among, and below the Boulder Clays in the north-eastern counties for anything resembling a Palaeolithic implement. I had no approach to success, however, till about a year ago, when in a bed of water-deposited gravel at a place called Limekiln Gill on the Durham coast, between the entrance of Hesleden Dene and Blackhall Rocks, some 4 miles northwest of Hartlepool, I found in the gravel cliff about 4 feet above the level of the beach a piece of yellow quartzite, which seemed to be artificially chipped. A short while ago I sent the specimen to Mr. Reginald A. Smith, B.A., F.S.A., of the British Museum, for his opinion, and somewhat to my surprise received the following reply: “I have little doubt about your implement, and Mr. Reid Moir, who saw it yesterday, agrees that it is definitely human. It is, indeed, interesting to find such a thing in situ, and one might expect to find it in some margin between the two principal boulder clays (Interglacial of East Anglia).” Such being the opinion of these experts, the specimen becomes one of very considerable significance, since the bed in which it was found underlies the main Cheviot and Northern drift or Purple clay, which at this spot is at least 70 feet thick and consists very largely of typical boulder clay.

Abstract. Although elevated ozone (O3) concentrations are observed in many areas within continental southern Africa, few studies have investigated the regional atmospheric chemistry and dominant atmospheric processes driving surface O3 formation in this region. The aim of this study was to conduct an assessment of comprehensive continuous surface O3 measurements performed at four sites located in continental South Africa. These sites were representative of regional background (Welgegund and Botsalano) and industrial regions (Marikana and Elandsfontein) in the north-eastern interior in South Africa as indicated by comparison with other sites in this region. The regional O3 problem was also shown with O3 concentrations being higher than 40 ppb at many sites in the north-eastern interior, while the South African air quality standard limit for O3 was regularly exceeded at the four sites in this study. O3 levels were generally lower at other background sites in the Southern Hemisphere compared to the South African sites, while similar seasonal patterns were observed. The temporal O3 patterns observed at the four sites resembled typical trends for O3 in continental South Africa, i.e. O3 concentration peaking in late winter and early spring, and daytime O3 peaks associated with increased photochemical production. The seasonal O3 trends observed in continental South Africa were mainly attributed to the seasonal changes in emissions of O3 precursor species and changes in meteorological conditions. Increased O3 concentrations in winter were indicative of increased emissions of O3 precursors from household combustion for space heating and the concentration of low-level pollutants near the surface. A spring maximum was observed at all the sites, which was attributed to increased regional biomass burning during this time. Source area maps of O3 and CO indicated significantly higher O3 and CO concentrations associated with air masses passing over a region where a large number of seasonal open biomass burning occurred in southern Africa, which indicated CO associated with open biomass burning as a major source of O3 in continental South Africa. The relationship between O3, NOx and CO indicated a strong dependence of O3 on CO, while O3 levels remained relatively constant or decreased with increasing NOx. The seasonal changes in the relationship between O3 and precursors species also reflected the seasonal changes in sources of precursors. The instantaneous production rate of O3, P(O3), calculated at Welgegund indicated that at least 40 % of O3 production occurred in the VOC-limited regime. These relationships between O3 concentrations and P(O3) with O3 precursor species revealed that large parts of the regional background in continental South Africa can be considered CO- or VOC-limited, which can be attributed to high anthropogenic emissions of NOx in the interior of South Africa. It was indicated that the appropriate emission control strategy should be CO (and VOC) reduction associated with household combustion and regional open biomass burning to effectively reduce O3 pollution in continental South Africa.

<p><strong>Abstract.</strong> The study presents the results of the application of a multidisciplinary methodology for a deeper understanding of historical buildings. 3D integrated surveys and stratigraphic methods can together make it possible to date the principle construction and evolution phases of historical buildings for which a thorough historical documentation does not exist for our time.</p><p>The case-study presented involves the Franciscan monastery and adjacent Immacolata church in Troina, which is a small medieval town located in the north-eastern part of Sicily.</p><p>The small number of historical records has only allowed for the dating of the monastery's foundation and of a few of transformation phases. Contrarily to this, various markings on the surfaces of the walls indicate rather the presence of numerous construction phases.</p><p>The inaccessibility of parts of the internal spaces, as well as the existence of a sharp incline of the road and of very high walls along scant sections of the road, are the reasons for having chosen to carry out a 3D laser-scanning survey campaign. It made it possible to document the overall area and the relationship between the different parts of the complex. The integration between 3D laser scanning and photo-modelling methods made it possible to highlight the details, anomalies, traces and signs of the stratifications over time. The results of this integrated survey were explained in a series of graphic elaborations in support to the following stratigraphic investigation, to put in order the numerous traces discovered.</p></p>
