This article analyzes the prospects of petroleum potential in Kurgan region. The relevance of the work is due to the high degree of development of the traditional oil and gas recovery areas of Western Siberia, which leads to the need to organize search activities in areas with a low density of hydrocarbon resources. We have analyzed the results of exploratory drilling in the area of the Alabuga river in Kurgan region, and have studied the history of detections of onshore oil occurrences there. Based on the results of the retrospective analysis, the research area was determined, field work was performed to determine the state of search wells in the area, and a collection of geochemical soil and liquid samples was selected. The analysis of the samples revealed that all of them contain methane and its homologues up to and including pentane. The genesis of light methane homologs is related to the processes of catagenesis; their detection on the surface indicates active processes of generation and migration of petroleum hydrocarbons. Based on the analysis of archival materials and estimated ground-based geochemical studies, a conclusion is made about petroleum potential in Kurgan region.

Documentation of ethnomusic (which is at the same time the first stage of its research) forms the base of sources of musical folklore (ethnomusicology), which creates the very possibility of all subsequent explorations. Ethnic music, as a whole, is formed by the totality of its regional manifestations, each of which must be recorded in sufficient completeness. However, some territories for various reasons even at the end of the twentieth century, were represented on the Ukrainian ethnomusical map very sparsely. It’s a paradox, but Kirovohrad region, located in the center of Ukraine, remained one of the least explored regions. Being a region of relatively late settlement, it was practically ignored by researchers (including ignored by the relevant scientific institutions) as an uninteresting periphery. One of those who in the late 1980s gave the start of the modern stage of documenting the musical folklore of the Kirovohrad region, its systematic professional recording, was a graduate of the Kiev Conservatory Nina Kerimova. For ten years of active field work, the collector has recorded nearly 7000 units of musical and ethnographic information from 80 settlements. These materials today make up nearly one third of the twenty-thousand regional audio archive, collected over the past 35 years by the joint efforts of folklorists, professionally engaged in field survey of the presteppe Right Bank and its adjacent steppe and eastern Podolian territories within the Kirovohrad region and the border areas of Cherkasy, Vinnytsia and Dnepropetrovsk regions. The purpose of this article is to summarize and make public the information about the nature and results of N. Kerimova’s collector`s activity. A systematized, meaningful, structured, concentrated and formalized approach makes it possible to include materials from her archive into the all-Ukrainian ethnomusical and ethnomusicological information field. Methods used in the article correspond to its set goal: factographic and factological, statistical, analytical and synthetic (the latter reveals patterns in the correlation of elements of an integral system). The article provides: a brief overview of the history of collecting musical folklore in the region; basic biographical information about the researcher; statistical data on the number and geography of her expeditionary records, specified to the culture-genre content of the materials recorded in each locus; data on respondents (their number, age, origin). The methods and preferences of the field work are described. The professional level of the work is attested, the high degree of scientific value of the collected materials is argued. The audio and musical publications, which include materials from the archive of N. Kerimova are listed. The materials collected by N. Kerimova are characterized (a) as a separate hermetic collection-archive, (b) as an important component of the cumulative array of records made in the region and (c) in the context of a holistic view of the region's traditional ethnomusical culture that has been effectively formed nowadays. Along the way, the author of the article deals with the issues of cultural-genre classification / attribution of folk musical works, archiving field materials (in particular, methods of passportization and codification of records), as well as the problems of documenting and statistical processing of materials recorded from migrants (local, intraregional, interregional), that were incorporated by the new folklore environment to a greater or lesser extent

First results of the excavation of the medieval castle of Dos Hermanas (Montemayor, Cordoba)In the south of the kingdom of Córdoba, there is the castle so-called Dos Hermanas, located in the municipality of the current town of Montemayor. It has been considered that the construction of the castle of this stately town was the result of the first moments of decline of the fortress of Dos Hermanas, located on the bank of the Carchena stream. Currently, a first excavation campaign has been carried out that brings us closer to the anthropic occupation of the site. At the same time, the archival research gives new information to the history of the site, exceeding the date of 1340, when Don Martín Alonso de Córdoba partially destroyed the Arab fortress of Dos Hermanas to build the castle of Montemayor. The first data extracted from the field work support the written sources, providing us with new data that allow us to make a more complete and novel interpretation. The survival of part of the facilities of the Dos Hermanas castle with an occupation from Roman times to the sixteenth century that shows the total non-depopulation of the place in the fourteenth century, as previously thought. A high degree of conservation of the structures found inside the wall enclosure appears a southern bay with stables with nine mangers. To the west, there is a vain and an angled staircase that allowed access from the parade ground until the round pass over the main door, which is also preserved. The objective of this proposal will be to present these first results of the archaeological intervention centered on the southern wall of the castle. These research works are accompanied by a consolidation project of the main structures, all financed by the Provincial Delegation of Cordoba and Montemayor Town Hall, whose continuity is developed in 2019 and 2020.

New petroleum paradigms in mature basins can be derived from re-examining geological parameters without bias of preceding theory. Kansas has a long history of oil and gas production with over 300,000 wells drilled. Precambrian basement faults in Kansas control the development of later structures, and probably, reservoirs. This study and re-interpretation of geologic history has identified a possible new play along reverse and thrust faults of the Humboldt Fault Zone along the eastern margin of the Nemaha uplift. This paper also suggests that the lack of significant petroleum production in the Salina basin is the result of migration barriers created by faults at the junction of two major fracture trends, rather than by limited local generation and migration.

1. An outline of the life history of Cephus pygmaeus Linnaeus is given.2. The parasites of Cephus are listed and are discussed briefly in relation to the particular parasite Collyria calcitrator Gravenhorst.3. It is shown that if the host larvae collected from wheat-stubble in autumn are used for the investigation of the extent of parasitism by Collyria, allowance must be made for the fact that the parasite Pleurotropis benefica Gahan is intrinsically inferior to Collyria, and that its cocoons must represent hosts left unparasitized by Collyria.4. In summer the adults of Collyria emerge, on the whole, earlier than those of the host Cephus. This suggests that at the beginning of the season of oviposition there will be a scarcity of hosts in comparison with the numbers of parasites wishing to oviposit. The relative activity of host and parasite during the egg-laying period is worked out on hypotheses of the average length of life of the individuals, and is shown diagrammatically.5. The Cephus larvae travel down the stem and hibernate at the base. When the wheat is cut, a proportion of the larvae and their parasites are removed with the straw. The way in which this may prevent the stubble material from giving a true indication of the degree of parasitism in the population as a whole is discussed.6. On the basis that 3910 hosts receive 3600 parasites, various hypothetical distributions are worked out arithmetically in order to find which type of discrimination between healthy and parasitized hosts gives an arrangement of parasites most in agreement with what has been found for Collyria in Cephus. The most satisfactory result is that obtained when it is assumed that the probability of an already parasitized host being re-attacked varies with the proportion of parasitized hosts. It is also shown that a shortage of hosts at a time of parasite activity may cause a high degree of superparasitism, thus giving a false impression of the parasite's power of discrimination.7. Suggestions for further field work are given.

The article continues the series of publications devoted to the forecast of oil and gas potential in the Middle Kura Depression. Systematization and analysis of published materials show that the effectiveness of prospecting and exploration for oil and gas depends on the fairness and accuracy of scientific ideas about the origin and patterns of hydrocarbon localization. The established heterogeneity of the structure of sedimentary basins and the uneven distribution of oil and gas deposits in them allows us to make a predictive assessment of territories based on historical-geological methods and a synthes analysis of criteria for assessing the prospects of oil and gas. These methods are based on fundamental research in geology, the most important of which are structural-tectonic analysis and the genesis of oil and gas-bearing structures, the study of geological and geochemical factors in the simulation model “Uniform continuous lowering”, the study of the staged conversion of organic matter in the catagenetic process and show the oil and gas windows, prediction of collector and overlying seal zones, study of organic substances dissolved in water and other hydrogeological factors contributing to the formation and prevent of oil and gas deposits. Analysis of the geological history of the first stage of research,the assessment of petroleum potential of the region. Based on the results of seismic surveys, we carried out paleotectonic reconstructions for the northwestern zone of the Ganja oil and gas-bearing region, which illustrate the maps of total thickness in the form of isopachic triangle, paleotectonic profiles and graphic of subsidence size. Modeling of structural surfaces made it possible to establish the historical development of not only local structures, but also to notice new features in the formation of chronostratigraphic surfaces, and to judge the tectonic regime of the sedimentation basin, to justify the mechanism of formation in the sedimentary cover of the Middle Kura depression, both of plicative dislocation and faulting as well as zones of oil and gas accumulation associated with them. The study can be considered as a positive argument when choosing the location of the prospecting well.

AbstractBefore we delve further into the relationship between migration and environmental change, it is important to gain more insight into the migration history of Moroccans going abroad and the specific environmental changes faced by people in Morocco. Therefore, in the first part of this chapter, we outline the history of Moroccan migration to Europe in general and to Belgium in particular. Morocco provides an interesting case of study with regard to environmental migration, as in the second half of the twentieth century, Morocco evolved into one of the world’s leading emigration countries. Moroccan migration is one of the unexpected outcomes in which colonial migration, labour migration, family reunification, and, most recently, undocumented migration combine. Hence, there is a high degree of internal differentiation and dynamics within the migrant population of Morocco (De Haas 2007).

“Paleobasin” is an area of long-term and steady subsidence of the Earth’s crust at a certain stage of geological development in the past, during which a body of sedimentary rocks of a mega-regional scale is formed, subsequently subjected to the influence of various kinds of geological processes leading to a reduction in its size, as well as changes in geometry and structure. Paleobasin is not a new concept. However, for petroleum, historical analysis was used only for those sedimentary strata that were not metamorphosed or collapsed into folds. As a result, the side zones of the basins and deep horizons were excluded from the basin modeling. The proposed approach to the analysis of paleobasins, regardless of the degree of their subsequent transformation, makes it possible to assess the petroleum potential of past eras, both primary and residual, especially in those zones and horizons that were previously derived from a general consideration of the prospects for finding oil and gas. The article shows the need for an integrated historical approach to the analysis of the oil and gas potential of the territory, both at the basin level and at the local level, including sedimentary strata and strata, which are often referred to as the “acoustic foundation”. Unfortunately, very often when modeling a promising object and assessing its resources or reserves, some of these attributes are taken for the type of work already done and do not adapt to a single model of oil and gas deposits, which reduces the reliability of the final result.

Ocular tuberculosis (TB) is an extrapulmonary tuberculous condition and has variable manifestations. The incidence of TB is still high in developing countries, and a steady increase in new cases has been observed in industrial countries as a result of the growing number of immunodeficient patients and migration from developing countries. Choroidal granuloma is a rare and atypical location of TB. We present a case of a presumptive choroidal granuloma. This case exposes that diagnosis can be remarkably challenging when there is no history of pulmonary TB. The recognition of clinical signs of ocular TB is extremely important since it provides a clinical pathway toward tailored investigations and decision making for initiating anti-TB therapy and to ensure a close follow-up to detect the development of any complication.
