The study presents materials on the status of aquatic biological resources and their habitat in the Dnieper River within the territory of the Russian and the Belarus. In the recent period, there has been hardly any complex fishery research in the upper reach of the river within the boundaries of the Smolensk Region due to the lack of commercial fishing; the same can be applied to the reach of the river within the Vitebsk Region in Belarus. The collection of materials and scientific and research accounting network surveys for monitoring the state of aquatic bioresources were carried out on the Dnieper River as part of the research in 2019 according to a preplanned grid of stations. When fishing for scientific research purposes, 20 net-stops of smooth frame nets were made in the Russian section, and 9 net-stops were made in the Belarusian section. In the Russian section of the Dnieper River, the species composition was 16 species of fish, and in the Belarusian section — 22 species. The main catch in the Russian section is roach 29% and chub 20%, in the Belarusian section bream — from 3 to 46%, roach — from 19 to 63% and gustera — from 1.8 to 33%, in a slightly smaller number of river perch (on average up to 10%). The share value of roach and guster tends to decrease from the upper to the lower areas, bream-on the contrary to increase, the value of perch is approximately equal in all areas. In the size structure of the caught fish species, there is a dynamic with a good reproductive potential.

The coenopopulations of Serratula centauroides in various plant communities of Transbaikalia have been studied. In the study areas 10 geobotanical descriptions were made in plant communities with the participation of S. centauroides. In the investigated area S. centauroides is found on dry rocky slopes, in herb and sandy steppes. Depending on the growing conditions, the density of individuals in coenopopulations ranges from 0.18 to 1.80 individuals per 1 m2. The highest occurrence of S. centauroides is noted in communities dominated by Gramineous and Artemisia: Gramineous-Artemisia-herb, Filifolium-Artemisia-Gramineous, Gramineous-Artemisia, Oxytropis-Gramineous and Allium-Artemisia. Studied coenopopulations S. centauroides are confined to the following communities: Filifolium-herb, Gramineous- Artemisia-herb, Sophora-herb, Filifolium-Artemisia-Gramineous, Gramineous-Artemisia, Agropyron- Carex, Carex-herb, Oxytropis-Gramineous and Allium-Artemisia. The phytomass, biological and exploitation resources, the possible volumes of annual harvesting of raw material of S. centauroides were determined. The phytomass of S. centauroides herb ranges from 8.10±3.46 to 75.93±19.55 g/m2 (air-dry raw material). The average phytomass of 1 individual of S. centauroides herb varies from 13.67±3.59 to 67.14±14.30 g (air-dry raw materials). The total biological resources of S. centauroides herb is 777.9 t (fresh raw materials) and 266.8 tons (air-dry raw materials). The total exploitation resources of S. centauroides herb is 224.7 t (fresh raw materials) and 79.8 t (air-dry raw materials). The possible volume of annual harvesting of raw materials of S. centauroides in the studied coenopopulations on the territory of the Trans-Baikal Territory and the Republic of Buryatia amounts to 37.5 t (fresh raw materials) and 13.3 t (air-dry raw materials).

The aim of organic agriculture is production of high quality food, which will contribute to human health, nature protection and conservation of the overall ecosystem. Globally, cereals are the most organically grown crop (3.3 million ha). The greatest production takes place on the European continent. The most cultivated species are as follows: wheat, maize, rice, barley, oat, sorghum, millet, triticale and buckwheat. China and USA are global leaders in cereal production in the organic system. Organic cereal production in the Republic of Serbia has a primary role and is performed on the area of 4251.94 ha. The majority of this production is done in the region of Vojvodina. According to obtained scientific results, nutritive value, and especially with a view to the status and requirements of the market, cereal production is extremely actual. Moreover, due to unlimited possibilities and market requirements, cereal production is a great challenge to agricultural producers.

Bengali language has been declared as the state language of the Republic in Article 3 of the Constitution of Bangladesh. Bengali is our mother tongue and we have achieved this at the cost of much blood. Moreover Bangla Bhasha Procholon Ain (Bengali Language Implementation Act) was made in 1987 for ensuring compulsory use of Bengali in courts and offices of Bangladesh. In spite of these provisions, English is still used in the judicial system (Higher Courts) in Bangladesh. Often delivering of judgments in English creates various problems for poor and illiterate person. People in our country speak in Bengali. Language of courts should follow the language of the common people. An attempt has been made in this article to assess the status and the enforceability of Bengali language with historical background, limitations of bringing into practice and some necessary measures for effective use of Bengali language in the courts.

AbstractA reanalysis of the data presented in a recent large twin study suggests that opposite-sexed (OS) pairs may be not as exhaustively tested as same-sexed (SS) pairs on genetic markers. This is contrary to an assumption I made in estimating that there are about 8 SS dizygotic pairs to every 7 OS pairs (thus impugning Weinberg's differential rule). If this assumption is false also in regard to the samples I discussed, then that estimate is unsound and Weinberg's rule is unscathed by empirical data. However, regardless of such considerations, there are strong theoretical reasons for questioning the status of Weinberg's rule. It is based on two assumptions, namely that p (the probability that a dizygotic twin zygote is male) is equal and independent for all dizygotic twin zygotes. Data are adduced here to suggest that both assumptions are false. The upshot is that, at present, without testing, we cannot know, of any given population, whether the rule holds or not. Otherwise, though Weinberg's rule may be useful (like Hellin's law) as a rule-of-thumb, it cannot be assumed as a basis for serious scientific argument.

The history of local government in South Africa dates back to a time during the formation of the Union of South Africa in 1910. With regard to the status of local government, the Union of South Africa Act placed local government under the jurisdiction of the provinces. The status of local government was not changed by the formation of the Republic of South Africa in 1961 because local government was placed under the further jurisdiction of the provinces. Local government was enshrined in the Constitution of the Republic of South Africa arguably for the first time in 1993. Under the interim Constitution local government was rendered autonomous and empowered to regulate its affairs. Local government was further enshrined in the final Constitution of 1996, which commenced on 4 February 1997. The Constitution refers to local government together with the national and provincial governments as spheres of government which are distinctive, interdependent and interrelated. This article discusses the autonomy of local government under the 1996 Constitution. This it does by analysing case law on the evolution of the status of local government. The discussion on the powers and functions of local government explains the scheme by which government powers are allocated, where the 1996 Constitution distributes powers to the different spheres of government. Finally, a conclusion is drawn on the legal status of local government within the new constitutional dispensation.

The status quo within international politics is that individual nation-states enjoy extensive and for the most part exclusive rights over the resources falling within their borders. Egalitarians have often assumed that such a situation cannot be defended, but perhaps some sophisticated defences of state or national rights over natural resources which have been made in recent years prove otherwise. This chapter critically assesses these various arguments, and shows that they are not sufficient to justify the institution of ‘permanent sovereignty’ over resources. Even insofar as those arguments have some weight, they are compatible with a significant dispersal of resource rights away from individual nation-states, both downwards towards local communities, and upwards towards transnational and global agencies.

ArgumentThis paper analyses a process of co-construction of knowledge and its multiple forms of communication in a country of the European periphery in the early twentieth century. It focuses on Lieutenant Manuel Soares de Melo e Simas, a politically engaged Portuguese astronomer, who moved from amateur to professional during the political transition from the monarchy to the republic. Melo e Simas paralleled his professional career in continuous activity of communicating science to the public in the context of republicanism in a double way, by responding to the agenda of republicanism and by playing an active role in shaping it. He aimed at educating lay audiences in the various ways of astronomy, and he reached out to as many people as possible by exploring a multitude of communication channels, from lectures to articles in newspapers and journals. Voiced often within newly created republican institutions, the praxis and the ideas of Melo e Simas helped to mold the new republican scientific ethos. By going beyond mere emphasis on scientism and positivism, usually taken to be the defining characteristics of the new republican ethos, this paper argues that science and the specificities of its multiple forms of communication were central to the way Melo e Simas shaped the republican ideology. Furthermore, popularization of science was used to legitimize the status of professional scientists at the same time that it helped reinforce their institutional setting, still to be negotiated in the forthcoming decades through a complex process which deserves further historical analysis.

Abstract Background This study aimed to describe the status of alcohol consumption and drug use among young adults as well as their determinants. Methods We conducted a cross-sectional study of 356 young adults (aged 18 to 24 years) living in Palau in 2013. The prevalence of self-reported alcohol and marijuana usage were compared within and between sexes, age groups, ethnicities, and education levels. Results The proportion of current drinking was higher in people aged 21–24 than in those aged 18–20 (73.2% vs. 60.9%, p = 0.09 in men and 48.3% vs. 30.0%, p = 0.02 in women), while that of marijuana use did not differ between the age groups. The proportions of current drinking and marijuana use were higher in Palauan than in other ethnicities (current drinking: 70.6% vs. 40.6%, p = 0.005 in men and 38.8% vs. 16.6%, p = 0.04 in women; lifetime marijuana use: 80.0% vs. 52.9%, p = 0.02 in men and 56.1% vs. 30.6%, p = 0.09 in women). The proportion of frequent (3 times or more) marijuana users was higher for the lower educated than for the higher educated (62.5% vs. 32.1%, p < 0.001 in men and 33.9% vs. 24.4%, p = 0.12 in women). Conclusions Sex, age, ethnicity, and education were significant determinants of alcohol and marijuana use.
