The Treaty on Friendship, Mutual Assistance and Postwar Cooperation between the Czechoslovak Republic and the Union of Soviet Socialist Republics signed on 12 December 1943 in Moscow had a fundamental impact on the orientation of Czechoslovak foreign policy at the end of the war and in the years that followed. At the same time, the lengthy negotiations in 1943, which ultimately resulted in signing the treaty in question, were one of the few moments during the war when Czechoslovakia became the object of an opinion clash between the Great Powers. In this study, which is based primarily on British and US documents (some of which have not been used before), the author analyses in detail the role of the Czechoslovak-Soviet treaty project in the policies of the two Western powers until the signing of the document, before assessing the impact of the treaty in concern on Czechoslovakia’s relations with the United Kingdom and the United States at the end of the war. He points out that neither the British nor the Americans were prepared to conclude a similar treaty with Czechoslovakia since both Western powers wanted the international security system to be based on foundations different from those which had repeatedly failed during the previous three decades. However, the signing of the Czechoslovak-Soviet Treaty dramatically reduced any chance for a federative or confederative arrangement in the region of Central Europe, as well as hopes for a multilateral treaty of alliance ensuring security in this region. For this reason, it was accepted without enthusiasm both in London and in Washington.
The Capsalidae are monogeneans parasitizing ''skin'', fins and gills of marine fishes. Some capsalids are pathogenic to cultivated fish and a few have caused epizootic events. It is a cosmopolitan family with broad host associations (elasmobranchs and teleosts, including sturgeons). Approximately 200 capsalid species are placed in nine subfamilies and 44-46 genera, some of which are well known (Benedenia, Capsala, Entobdella, Neobenedenia). Sturgeons host two capsalid species (Nitzschiinae) and 15 species in five genera are reliably reported from elasmobranchs. The combination of ancient (shark, ray, sturgeon) and modern (teleost) host fish lineages indicates that capsalid evolution is likely a blend of coevolution and host-switching, but a family phylogeny has been lacking due to deficient knowledge about homologies. The current phenetic subfamilial classification is discussed in detail using a preliminary phylogeny generated from large subunit ribosomal DNA sequence data from representatives of five subfamilies. Monophyly of the Capsalidae is supported by possession of accessory sclerites. Hypotheses are proposed for the possible radiation of capsalids. A suggestion that Neobenedenia melleni, a pathogenic species atypical due to its broad host-specificity (>100 host teleost species from >30 families in five orders), may be a complex of species is supported from genetic evidence. This may explain peculiarities in biology, taxonomy, host associations and geographic distribution of N. 'melleni' and has implications for fish health. Holistic studies using live and preserved larval and adult capsalid specimens and material for genetic analysis are emphasised to further determine identity, phylogeny and details of biology, especially for pathogenic species.
We consider the homogeneous time-dependent Oseen system in the whole space R 3 . The initial data is assumed to behave as O(|x| −1−ε ), and its gradient as O(|x| −3/2−ε ), when |x| tends to infinity, where ε is a fixed positive number. Then we show that the velocity u decays according to the equation |u(x, t)| = O(|x| −1 ), and its spatial gradient ∇xu decreases with the rate |x| −3/2 , for |x| tending to infinity, uniformly with respect to the time variable t. Since these decay rates are optimal even in the stationary case, they should also be the best possible in the evolutionary case considered in this article. We also treat the case ε = 0. Then the preceding decay rates of u remain valid, but they are no longer uniform with respect to t.
The local well-posedness for the Cauchy problem of the liquid crystals system in the critical Besov space is established by using the heat semigroup theory and the Littlewood-Paley theory. The global well-posedness for the system is obtained with small initial datum by using the fixed point theorem. The blow-up results for strong solutions to the system are also analysed., Sen Ming, Han Yang, Zili Chen, Ls Yong., and Obsahuje bibliografii
The case study of a ground steps creation due to underground mining in Upper Silesia Basin, where for many years was conducted intensive hard coal extraction has been presented in this paper. This type of linear discontinuous deformations is considered as an important threat to the surface building constructions and elements of underground technical infrastructure. This threat is even more important, that presently still we do not have methods for predictions of such phenomena, and protection of building constructions against such damages is difficult, if not impossible. On the basis of the analyzes results shown in the paper, the following factors were pointed, that favor the formation of mining-induced ground steps: the presence of fault outcrops in the vicinity of extraction fields, multiple extraction in several coal seams led to the same border and large values of tensile horizontal strain., Piotr Strzałkowski and Roman Ścigała., and Obsahuje bibliografické odkazy
Prediction of the final transferred fat volume is essential for the success of fat grafting, but remains elusive. Between 20 and 80 % of the initial transplanted volume can be creabsorbed. Although graft survival has many determinants, CD34+ progenitor cells from the vascular stroma of adipose tissue play a central role by promoting growth of blood vessels and adipocytes. We aimed to verify the hypothesis that a higher proportion of total CD34+ cells in the transplant is associated with better preservation of the graft volume. Human lipoaspirates from 16 patients were processed by centrifugation and two grafts per donor were subcutaneously injected into 32 nude mice in 1 ml volumes in the right upper flank area. The volume of each graft was measured using a preclinical MRI scanner immediately after grafting and at three months. The percentage of CD34+ cells in the graft before implantation was determined by flow cytometry. The final graft volume at three months after implantation directly correlated with the percentage of CD34+ cells in the grafted material (r = 0.637, P = 0.019). The minimum retention of the fat graft was 28 % and the maximum retention was 81 %, with an average of 54 %. Our study found that fat retention after fat transfer directly correlated with the fraction of CD34+ cells in the graft. The simple and fast determination of the CD34+ cell percentage on site can help predicting outcomes of fat transplantation. and Corresponding authors: Ondřej Měšťák, Luděk Šefc
We compute the central heights of the full stability groups S of ascending series and of descending series of subspaces in vector spaces over fields and division rings. The aim is to develop at least partial right analogues of results on left Engel elements and related nilpotent radicals in such S proved recently by Casolo & Puglisi, by Traustason and by the current author. Perhaps surprisingly, while there is an absolute bound on these central heights for descending series, for ascending series the central height can be any ordinal number., Bertram A. F.

The aim of the paper is to trace the development of the grammatical structure of the vernacular (colloquial) Chinese language through the changes which took place in the grammatical system (specifically in the system of function words) during the 3rd-14th centuries. In other words, I intend to closely follow the entire process of the changes from the moment the function element originated up to its status (or disappearance) in the modern language. To fulfill the task a thorough examination of an extensive body of source-material was undertaken. A precise selection of the source-material was the first step towards a successful response to the proposed project. With regard to the paper under consideration the following source-materials were carefully examined: the early Chinese translations of the Buddhist works (as the main source) for the Liuchao epoch, the Chan-Buddhist yulu for the Tang, the texts in the ss genre and San Chao bei meng hui bian for the Song-Yuan period. The essay consists of three parts: the grammar of the 3rd-5th cc A.D., or Liuchao period, Chinese grammar of the Tang Dynasty, and the changes undergone during the Song-Yuan epoch.
Let $(\Omega ,\Sigma )$ be a measurable space, $X$ a Banach space whose characteristic of noncompact convexity is less than 1, $C$ a bounded closed convex subset of $X$, $KC(C)$ the family of all compact convex subsets of $C.$ We prove that a set-valued nonexpansive mapping $T\: C\rightarrow KC(C)$ has a fixed point. Furthermore, if $X$ is separable then we also prove that a set-valued nonexpansive operator $T\: \Omega \times C\rightarrow KC(C)$ has a random fixed point.
The liver fluke Clonorchis sinensis (Digenea) is a high-risk parasite that causes serious diseases such as cirrhosis, carcinogenic liver damage and clonorchiasis in East Asia. This study was conducted to evaluate the relationship between stress/endocrine hormones and inflammation induced by infection as well as the expression of heat shock proteins (hsp-27, hsp-90), cox-2 and cytokines in the livers of hamsters infected with C. sinensis. The average body weight of infected hamsters decreased up to 25% compared with that of the control group, and bile duct hyperplasia with inflammation, liver fibrosis and hepatic necrosis were observed in C. sinensis-infected livers. The expression of hsp-27, hsp-90, and cox-2 was significantly increased in the livers of C. sinensis-infected hamsters compared with the control group. Moreover, the expression levels of inflammatory cytokines (IL-1β, IL-2, TGF-β2 and IFN-α1) were markedly increased in the livers of the infected group compared with those of the control group. Consistently, plasma IL-3 and IL-6 levels gradually increased during the infection period, and the concentration levels of testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), corticosterone, and adrenocorticotropic hormone (ACTH) in C. sinensis-infected hamsters increased over 25%, compared with those of the uninfected normal group. These results demonstrate that C. sinensis infection may increase the expression of hsp27, hsp90 and cox-2 as well as it may cause periductal fibrosis, chronic inflammation and hepatic necrosis in the liver. Furthermore, the results indicate that C. sinensis infection induces not only stress-induced hormone imbalance but also the sustained secretion of inflammatory cytokines through chronic stress/stimuli.
