The focus of this study is to summarize the data on the distribution and foraging preference of Bombus (Megabombus) consobrinus Dahlbom, 1832 in the European North of Russia. The range of B. consobrinus in this region mostly repeats the disjunctions of the range of Aconitum septentrionale that is also known in Scandinavia. In other regions of Northern Eurasia, the close relationship of B. consobrinus with Aconitum is not obvious. This bumblebee species may be regarded as oligolectic in Northern Europe and the European North of Russia. We assume the presence of a coadaptive relationship of this bumblebee species with A. septentrionale in this region that presumably have been caused by the complex history of B. consobrinus in the European North.

The article deals with the problem of the spread of artillery weapons from the East to the West through the territory of the Eurasian steppes. Among the regions important for the devel-opment of firearms were countries with Islamic culture, which are currently part of the Russian Federation and the CIS. They were one of the most important links in the movement of new technologies from the East to Europe. Evidence of the development of artillery in the northern Muslim countries is not only written sources, but also finds of genuine medieval weapons. The author shows that the Muslim peoples of northern Eurasia have contributed to the world process of the development and spread of firearms. The article substantiates the view that in the territory of Russia powder technologies, the newest at that time, began to be used much earlier than in Western Europe. The author also identifies a number of areas of research into the history of powder technologies in the medieval Muslim world, such as sources of information, regions, landscapes, the main ways of spreading technologies, as well as terminology from the standpoint of cultural relationship of languages

This paper summarizes the history of and information on bovine herpesvirus type 4 (BoHV-4) from the first isolation to the most recent results. For almost twenty years BoHV-4 has been considered a typical herpes ‘orphan’ virus, which infects several species but causes no illness. The latest experiments revealed the close relationship of this virus with the immune system and other tissues. The virus was even considered as a possible candidate for a vector vaccine. BoHV-4 as a strange herpesvirus has several features which are not characteristic of other herpesviruses, such as several latency sites, persistence in serum, dividing cells necessary for virus replication, and the wide host range. In addition to describing the main features of the virion, replication, clinical signs, nomenclature problems, this review intends to concentrate on the new and strange results coming out from several laboratories worldwide. It is also suggested that because the virus combines several properties of various herpesvirus subfamilies and because of its close relationship with the immune system, it may deserve further attention as a representative of a potentially new genus within the Gammaherpesvirinae subfamily.

AbstractIn the deep sea, the phylogeny and biogeography of only a few taxa have been well studied. Although more than 200 species in 32 genera have been described for the asellote isopod families Desmosomatidae Sars, 1897 and Nannoniscidae Hansen, 1916 from all ocean basins, their phylogenetic relationships are not completely understood. There is little doubt about the close relationship of these families, but the taxonomic position of a number of genera is so far unknown. Based on a combined morphological phylogeny using the Hennigian method with a dataset of 107 described species and a molecular phylogeny based on three markers (COI, 16S, and 18S) with 75 species (most new to science), we could separate Desmosomatidae and Nannoniscidae as separate families. However, we could not support the concept of the subfamilies Eugerdellatinae Hessler, 1970 and Desmosomatinae Hessler, 1970. Most genera of both families were well supported, but several genera appear as para- or even polyphyletic. Within both families, convergent evolution and analogies caused difficulty in defining apomorphies for phylogenetic reconstructions and this is reflected in the results of the concatenated molecular tree. There is no biogeographic pattern in the distribution as the genera occur over the entire Atlantic and Pacific Ocean, showing no specific phylogeographical pattern. Poor resolution at deep desmosomatid nodes may reflect the long evolutionary history of the family and rapid evolutionary radiations.

435 arterial occlusions were treated with streptokinase over a period of 3 days. A continuous streptokinase regimen with a maintenance dose of 100 000 u SK/h was administered. The successful removal of femoral obstructions was possible in 8.9%. A complete dissolution of the iliac thrombus masses had been achieved in 19%. 41 aortic occlusions were treated. The treatment was capable of removing the aortic obstructions in 24%. It became evident that there was a close relationship between the average occlusion time and the respective clearance rate. Por example, in patients undergoing lysis treatment during the very first two weeks after femoral occlusion, clearance was established in 75% and best lytic results were achieved if the history of iliac occlusion was well below 3 months duration. The relationship of vessel clearance rate and walking distance showed, that on the average there was no lengthening in walking distance where treatment had failed (no vessel clearance obtained). On the other hand, a significant average rise in walking distance from initially 325 up to 800 meters (p < 0.05) was seen when vessels clearance had been recorded.

Studies on maqasid al-shari�ah have been widely written and reviewed by researchers of Islamic law. Some have written about the maqasid al-shari�ah�s concept, the figures� thought, and its application to various Islamic law and social issues. As a new study, maqasid al-shari�ah is widely studied in the context of renewing Islamic law, however little discuss about history of maqasid al-shari�ah and relations with usul al-fiqh. Because historically, the birth of maqasid al-shari�ah can�t be separated from development of usul al-fiqh through the scholars usul al-fiqh. As well as in terms of methodology, maqasid al-shari�ah have a close relationship with method istinba? al-�hkam in usul al-fiqh,� as qiyas,� maslahah al-mursalah, al-�ari�ah �and istihsan. While in terms of application, maqasid al-shari�ah together with usul al-fiqh namely departing from the proposition of naqli (revelation) and �aqli (reason) which is global and analyzes various opinions in deciding Islamic law. It�s just that usul al-fiqh is dominated by linguistic aspects, meanwhile the maqasid al-shari�ah emphasizes the divine aspect behind the law.� That�s why to see relationships among maqasid al-shari�ah and usul al-fiqh, this research uses library research method or literature review by researching the main sources which discusses about relations maqasid al-shari�ah and usul al-fiqh in terms of historical, methodological and applicative.

Caminella Lendenfeld, 1894 is a poorly known Geodiidae genus with unclear phylogenetic relationships. In order to find new lines of evidence that could shed light on the evolutionary history of Caminella, we decided to revise type material and museum material, as well as examine new material from underwater caves and deep-sea ecosystems. In doing so, we formally show that Isops maculosus Vosmaer, 1894 and Caminella loricata Lendenfeld, 1894 are junior synonyms of Caminella intuta (Topsent, 1892). We discuss different spicule morphological phenotypes in C. intuta, which may be linked to silica availability. We also discovered two new species of deep-sea Caminella: 1) from Cape Verde (Caminella caboverdensis sp. nov.) and 2) from seamounts located south of the Azores archipelago and the North of Spain (Caminella pustula sp. nov.). We reveal that Caminella sterrasters have complex surface microstructures, unique amongst the Geodiidae, where actin tips are linked to each other. Molecular markers (COI, 28S (C1-D2) and 18S) sequenced for some specimens led to new phylogenetic analyses, which continue to suggest a close relationship of Caminella with the Erylinae and Calthropella; these affinities are discussed in light of morphological characters.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Introduction. The organization of transport links and the bridge building in cities located on the banks of wide rivers has always been one of the most important tasks of the local administration. The study of the history of bridge building allows not only to trace the process of modernization of different regions of the country, but also to help in solving similar problems of our time. Nevertheless, the history of Russian bridge building is poorly studied. The purpose of the article is to determine the characteristics and features of the organization of bridge building in big cities of the European North of Russia as a way to solve one of the problems of urban infrastructure in the early XX century. Materials and Methods. The sources for this study are the documents of the State archive of the Arkhangelsk region, published documents on the history of Vologda, articles in the local periodicals of the early XX century. The analysis of the studied problem used a systematic approach, the method of economic analysis, historical and historical-comparative methods. Results and Discussion. The building of permanent bridges was a need for the development of Arkhangelsk and Vologda. In Vologda the two wooden bridges were built in the middle of XIX century on city funds and in the future these bridges were repaired or rebuilt. The Arkhangelsk city authorities did not hurry to solve a problem of city infrastructure by own efforts and a long time they used the floating bridge. The lack of experience in the building of large bridges and the desire to save money led to the rapid destruction of the first permanent bridge in Arkhangelsk. Conclusion. The Development of trade and industry in cities of the European North of Russia, such as Arkhangelsk and Vologda, led to the expansion of their territory and the emergence over time, the so-called third parts of the cities. Despite the comparable size of the population of the districts located across the river, the process of connecting them with bridges to the rest of the city went at different rates, which depended on the attitude of the local administration to the problem of urban infrastructure.
