Мировая нефтепромысловая практика показывает, что в условиях неоднородных трещинно-поровых пластов высокопроницаемые интервалы, доля которых составляет обычно 30 - 40 %, зачастую являются и основными путями опережающего обводнения скважин, что является очень большой проблемой, требующей привлечения дополнительных материальных ресурсов по борьбе с обводнением скважин и коррозией нефтепромыслового оборудования. The world oilfield practice shows that in the conditions of heterogeneous fractured-porous formations, high-permeability intervals, the share of which is usually 30-40%, are often the main ways of anticipatory watering of wells, which is a very big problem requiring additional material resources to combat water-cutting and corrosion of oilfield equipment.

Textual evidence preserved in two still unpublished manuscripts strongly suggests that there once existed an alternative version of Miskawayh’s Fawz al-aṣghar, the Minor Book of Triumph. The article discusses possible explanations for why Miskawayh may have composed two recensions of his Fawz and compares structure and content of the alternative version with the edited standard version. The one passage which is contained in the alternative Fawz only is presented in Arabic with an English translation. Part of this additional material is parallel to al-Fārābī’s Iḥṣā’ al-‘ulūm, namely its division of natural sciences, and may ultimately derive from a no longer extant treatise by Paul the Persian. An appendix provides the Arabic text and English translation of a hitherto unknown fragment of al-Balkhī in which he discusses Plato’s saying that the world has a causative, but no temporal beginning.

Governance, the world over, has become the main framework for assessing the effective utilization of human and material resources for the development of a nation or an organization. This paper explores the link between governance failure, violence and its implication for internal security in Rivers State. The level of violence in the state is high and increasing particularly since 1999 when the nation returned to civil rule. Violence such as inter and intra communal conflicts, cult violence, armed robbery, kidnapping, political violence among others, now writ large in the state. The study utilized the qualitative and content analysis. The paper reveals that the pervasive nature of violence with negative effect on the internal security is the fall out of the failure of the governance in the state. The paper recommends, among other things that, good governance is a tool for empowering the people, which in turn, will reduce unemployment, poverty, marginalization and the recourse to violent aggression in the state.

Abstract The constant growth of the population increases the demands on raw material resources, which is reflected in increasing pressure on the environment. The impact of mankind on the environment is nowadays an increasingly acute problem, which is being addressed by the governments of individual countries, not only the EU, through legislative interventions. The most addressed areas are the issue of production and subsequent waste management. Waste production in the world has been growing for a long time, which causes considerable problems for individual countries. Each country is currently looking for the optimal way of waste management to reuse it as secondary raw material. In this paper, we analysed twenty-eight EU countries in terms of production and waste management and found significant differences between countries. We looked for factors that lead to different results between countries in the production and management of waste, based on the population, the size of the country to the indicators of living standards, and legislation applicable to those countries.

Educational Administration is the whole process of collaboration of two or more people by utilizing all available personnel and material resources and appropriate to achieve the educational goals that have been set effectively and efficiently.All resources used will be regulated for use, so that there is no waste in achieving the goals that have been determined together. The purpose of administration in general is that all activities support the achievement of educational goals or in other words the administration used in the world of education is sought to achieve educational goals.

AbstractThe type material ofAgraulos antiquusSdzuy, 1961 from the La Herrería Formation, northern Spain, is revised together with additional material and included in the new genusLunagraulos. The stratigraphical range ofLunagraulos antiquus(Sdzuy, 1961) – occurring below that of the trilobite species of the generaLunolenus,MetadoxidesandDolerolenusin the type locality of Los Barrios de Luna in the province of León, northern Spain – and the accompanying ichnofossil assemblage demonstrate an Ovetian age (lower part of Cambrian Stage 3, currently being discussed by the International Subcommission on Cambrian Stratigraphy) for this species. Moreover, the trilobiteLunagraulos tamamensisn. gen. n. sp. is found in the Tamames Sandstone near the village of La Rinconada in the province of Salamanca, central Spain. The biostratigraphical position of this new taxon and its accompanying ichnoassemblage is also analysed and assigned to the lowermost Ovetian Stage. The genusLunagraulosis therefore the oldest agraulid found in the fossil record. The exceptional presence ofLunagraulosin a marine coarse siliciclastic succession – a facies rather typical for the ichnofossilsCruzianaandRusophycus, some of the oldest signs of trilobite activity – suggests that first trilobite representatives may have inhabited high- to middle-energy, marine environments. This hypothesis may also explain both the taxonomic and biostratigraphic heterogeneity of the first trilobite genera appearing across the world, due to preservation problems in this type of facies. Comparison of theLunagraulos biostratigraphy with other coeval Spanish fossil assemblages allows us to propose its intercontinental correlation with the oldest records of currently known trilobites.

Although Eurocentric scholars theorize the world in terms of Western evolutionary progress rather than de-evolutionary retrogression, this paper takes a different perspective. Forced to transition away from their tangible and intangible heritages, from their families and marriages, cultures, societies, polities, and economies in ways that legitimized imperial claims to res nullius (unowned resources) and terra nullius (empty land), some indigenous people wittingly and unwittingly increasingly devolved their heritages to the colonialists that benefited from the African transitions. The point here is that unlike “Bushmen” and those that practiced transhumance, contemporary Africans are forced to transition, to change and to transform away from owning and controlling their tangible and intangible resources, including land, culture, laws, religions, polities, economies, livestock, families, marriages, and so on. Whereas “Bushmen” and transhumance migrated and transitioned while retaining ownership and control over their land, forests, livestock, and so on, contemporary Africans are forced to transition in ways that divorce them from their families, marriages, cultures, religions, polities, and from ownership of their material resources. Because Eurocentric forms of transition put African institutions and resources on the chopping boards, we argue that this kind of transition is cannibalistic. Made to believe that transition is easier to accomplish without the supposed burden of repossessing ownership and control over one’s resources, Africans are witnessed as disinherited and wandering around the world arguably in ways that even precolonial “Bushmen” and transhumance pastoralists would not envy. There is no justice in “transitional justice” that transitions indigenous people from their heritages.

We are all familiar with the idea that the Church is in the world but not of it, and that too great a preoccupation with earthly things may compromise the Church’s other-worldly objectives. One thinks of the extravagance of a Renaissance pope such as Leo X, reputed to have said, ‘Let us enjoy the papacy, since God has given it to us’: or of an ancien régime prelate like the Archbishop of Mainz, who arrived for the coronation of the Emperor Joseph II with a retinue of fourteen sumptuous carriages: or, in our own time, the Vatican’s reported links with some of the shadier elements in the world of international finance. Yet, it is equally obvious that lack of adequate material resources can act as a serious impediment to the Church’s mission to go forth and teach all nations. Excessive poverty, like excessive wealth, brings its own problems. As the adage has it, not money itself but the desire for money is the root of all evil. Excessive poverty and the desire for money are the themes which I wish to pursue in this paper, in the context of the Scottish Catholic Mission in the eighteenth century, and more specifically as they relate to the so-called Jansenist quarrels which divided the Mission in the 1730s and 1740s.

Summer profiles of sea-water temperature, salinity and flow were obtained on George VI Ice Shelf near its northern ice front. At each depth, temperature salinity and density show little variation between sites. Their respective variation to 250 m depth confirms a linear temperature-salinity dependence. This is the first place in the world where observations confirm precisely the form of the T-S diagram predicted for fresh ice melting in sea-water. Both tidal and residual flow are small, except at the western margin of the ice front, where a strong outflow is concentrated immediately beneath the ice shelf. The observations lead to a simple circulation model for the ice-shelf regime. Warm Deep Water flows southwards into George VI Sound, replacing the colder water that spreads northwards in the surface outflow. Thermohaline exchanges beneath the ice shelf determine the salinity profile, which itself provides evidence of upwelling. Estimates can be made of the basal melt rate of the ice shelf. The rates vary from around 10 m a−1at the ice front to an average value for the ice shelf of order 1 m a−1. The average value is consistent with earlier estimates from surveys of ice-shelf strain.
