In order to study the freezing front characteristics of alpine tunnels under the condition of wind flow field and relying on the Osaka Mountain tunnel in Qinghai Province, the physical model test of an alpine tunnel was built. By using the Surfer software combined with the laboratory test data, the radial and longitudinal temperature variation trends of the tunnel were obtained, and the overall temperature vector graph of the tunnel was simulated; the radial and longitudinal evolutionary laws of a freezing front in an alpine tunnel under airflow conditions were systematically analyzed, and the radial and longitudinal governing equations of a freezing front in the tunnel model under airflow conditions were proposed. The results show that: With the decrease of the test air temperature, the thermonuclear area in the surrounding rock gradually shrinks, the frozen area of surrounding rock at the bottom of the arch gradually increases, and the frozen area of surrounding rock at the top of the arch gradually expands to the interior of the mountain. The influence degree of ventilation on the longitudinal and radial temperature distribution of the tunnel is obvious, and the greater the wind speed, the greater the influence degree. In particular, the fluctuation range of the longitudinal temperature distribution of the tunnel is more extensive under the influence of ventilation. The freezing front distance in the inverted arch area is the largest, and the expansion distance of the freezing front in the wall foot area is obviously higher than that in the vault; the variation of the longitudinal freezing front at different positions of the tunnel shows parabolic attenuation and with an increase in tunnel depth, the trend of freezing front gradually eases and becomes stable and disappears; the three radial regions of the freezing front and the longitudinal quadratic parabola governing equations can predict the specific distribution characteristics of the freezing front at different depths of the tunnel.

The present article concerns the problem of the contradiction between striving to maintain in the designed and implemented buildings of large volume in Polish area around the Tatras, in which it is justified to use current building technologies, including prefabricated buildings construction methods, and the need to continue the characteristic architectural forms of Tatra region. The demonstrated examples of architectural formation of buildings constructed during the interwar period-made for the needs of International Winter Olympics FIS, they used of the typical patterns of farms for the Alpine region. Such on example provides the evidence for the cultural pressure of a new function, i.e. skiing. Such an influence cannot be easily and consistently opposed in terms of logic performance of Tatra style current examples.

The Rupicaprini originated during the Miocene in Asia and dispersed during the late Miocene-early Pliocene, the Villafranchian, and the middle Pleistocene. Rupicapra and Oreamnos spread respectively to Europe and to North America in the middle Pleistocene. The Villafranchian Procamptoceras may be considered to be the closest known form to Rupicapra's ancestor. Rupicapra evolved during the middle and late Pleistocene in west Eurasia. At the beginning of the Würm glaciation the two closely related species R. pyrenaica and R. rupicapra were in existence. The former was already geographically split into Spanish-Pyrenean and central-southern Apennines groups, while the latter species ranged from the Caucasus to the Alpine Arch. R. pyrenaica shows more conservative features and possibly differentiated directly in western Europe from older representatives of the genus that migrated to western Europe in the middle Pleistocene. The cold-adapted Alpine chamois may have differentiated in eastern Europe and then migrated west-ward because of the advent of dry climates in the east Mediterranean and Pontic regions. The Alpine chamois failed to spread to the warmer southernmost regions of Europe that became a refugium area for R. pyrenaica. This dispersal hypothesis explains the morphologic, biometric, electrophoretic, and behavioral differences among modern chamois populations.

Full textAbstract:
The european Alpine “stone arch” has its own natural and cultural identity. It represents “proto-architecture” that offers artistic inspiration, formal references, therapeutic effects. Slovenia and its Alps are small (like a fractal pattern of the big ones), but diverse in their landscapes, settlement culture and architectural traditions. Historically we were always part of Middle European cultural context (between the Alps, Mediteranean and Pannonian plains). Mostly part of bigger states, their culture reflected in built environment and architecture: from regulated order of the monarchy, the transition to modernity between WWI and WWII, “self-made” modernism of socialism, global capitalism free market trends after independance. The result is manifested in dispersed “urban sprawl” territories, a theme of “healing process” for younger urban planning and architectural generations to face with. Luckily less in the Alps with their strong traditions and topographies, where many compact historic settlements still witness their original urban matryx, (medieval) “spatial language” with its organic logic and very precise urban wisdom. Some extraordinary designers in Slovenia helped to create high level of architecture culture in XXth century (also in the alpine space): besides two great personalities, Maks Fabiani and Jože Plečnik, the latter started – together with Juan Vurnik – with “Ljubljana school of architecture”, there was also his follower Edvard Ravnikar (who worked also at Le Corbusier’s), who continued with the architecture. school and raised many good, modern architects. After the independence (1991) the younger generation reflects global trends, but also continues with architecture of high quality, found in some beautifull, diverse projects in the Alps. Today our alpine communites care more for their urban heritage and renew it, reurbanise their squares, streets and parks and support models of sustainable development, in which high level of building culture is an essential part of.

In the paper a model of the formation of the folded-covering-block structure of the Carpathians at a time interval that envelops Late-Hercynian and Alpine events is substantiated. Moreover, this concerns the Outer Carpathians, but the whole Carpathians arch was characterized without going into details, a critical estimate is expressed for application of such terms as terrains, accretion prism, suture, subduction and Transcarpathian fault. It is shown that formation of the Carpathians occurred through several stages under the influence of different-directed, manly horizontal, movements, as a result of which was destruction of early formed Hercynian continental crust, laying of geosynclinals troughs, formation and further transformation of the basement of the Flysch Carpathians, its collision with Eurasian continental edge, underling of the latter under flysh complex. After completion of these processes mainly vertical movements took place that lineally formed the structure of the Carpathians as folded-covering-block one. As a result of the last event (Pliocene-Pleistocene), a differential development of intensive fracturing occurred with the influx of hydrocarbons and filling traps formed up.

ABSTRACT The geological community has broadly accepted that the region of NE Africa and NW Arabia deformed under tension during the post-Hercynian disintegration of northern Gondwana. Further, it has also generally accepted that sedimentation occurred within extensional half-grabens that formed along the length of what was then the southern margin of the Neo-Tethys Ocean. Consensus is that Alpine age compression then forced inversion of these half-grabens to form the well-known Syrian Arc structures that stretch from the Western Desert of Egypt to NE Syria. As new data has become available (Enclosures I and II), there are indications that an alternative mechanism, founded in continuous compression rather than extension then compression, better explains the tectonics and sedimentary history of the region since the late Palaeozoic. Data from Syria, Jordan, the Levant and Egypt demonstrate that distinct post-Hercynian Orogeny, Tethyan and Alpine sequences (basins) lie on a final, deeply eroded and folded Hercynian Unconformity, and that this surface refolded post-Hercynian time to form the confining walls of a single trough extending from NE Syria to the Western Desert of Egypt. Prior to the deposition of the first Tethyan basin in the late Carboniferous, the Hercynian Unconformity surface deformed to establish a plate-scale arch, the Levant Arch, that extended from NE Syria and southern Turkey, over 1,500 km southwest to the three corners region of Egypt, Sudan and Libya. This arch refolded in the late Palaeozoic to form the early Levant Trough composed of the Palmyride Trough, its extension under the Eastern Mediterranean and the Levant, through the Sinai and into western Egypt. Contrary to the now established idea that the southern margin of the Carboniferous–Permian Tethyan Ocean was a “passive margin”, the trough and internally constrained basins, slowly narrowed and deepened under continuous compression from the southeast from at least the late Palaeozoic to the Present. Each internal, distinct basin sequence is well defined by long periods of slow, low-energy, laterally persistent, sedimentation, separated from underlying and overlying basin sequences by almost equally long periods of erosion or non-deposition, coincident with increased regional structuring and volcanism. Each new basin, following a cessation of this regional structural activity, found itself nested within its predecessor, with the older basin lying slightly counter-clockwise to the younger. It is proposed that counter-clockwise, regional (and basin) rotation was facilitated by newly documented NW-oriented cross-shears, with inter-basin periods of erosion or non-deposition due to whole-basin (regional) uplift, forced by trough narrowing. Tectonic-scale geologic features, such as cross-basin and regional shears, trough margin uplift and northwest migration, laterally extensive, sheet-like sedimentation, sediment feathering onto unfaulted margins, regional erosion related to whole-basin uplift and massive flank gravity sliding with resultant down-slope buckle folding, taken together, attest to compression as the driving agent. Whole-basin and regional, counter-clockwise rotation through time, suggests a constant direction of compression. Understanding the correlation of sedimentary fill to local and regional structural events brings new insight to the deformation of the northern regions of Gondwana during the closure of Tethyan oceans. This model may also apply on a larger scale of whole-plate deformation.

In order to understand the process of neolithisation of Southeastern and Central Europe, must be underlined the important role played by Transylvania through the numerous springs and salt lakes. The whole Carpathian arch of Transylvania is surrounded by impressive salt sources (Map 1). After a cold period in Europe between 6300-6100 BC, around 6000 BC there is a heating that corresponds to Greece and Anatolia with very hot and dry periods, which causes small pastoral communities to migrate from the Greek-Macedonian areas to the north. These first shepherds’ communities with sheep flocks, defined with a general term, as Early Neolithic, migrate northwards and sit in salt areas. In the Carpatho-Danubian Basin, this civilization is defined by archaeologists with the term Starčevo-Criş culture. The first horizon was defined as Monocrom- Frühkeramik and Starčevo-Criş IA respectively (shortly SC). Very soon, finding out the beneficial conditions (pastures, forests, mountains with alpine pastures, but especially salty springs), other communities with large cattle come, laying the foundations of some important Early Neolithic sites in Transylvania: Cristian, Ocna Sibiului, Miercurea Sibiului, Gura Baciului and those in Apahida – Cojocna zone. Migration after migration and diffusion sought and used salt sources which together with the environmental factor (pastures, forests, and alpine meadows) contributed to the neolithisation process. In SE Transylvania, Moldova, central and north Crişana neolithisation process starts only with the evolved phases of the Starčevo-Criş culture. The most interesting and important discoveries related with the end of Early Neolithic are those of Lunca – Poiana Slatinii (Neamţ County). The salt roll for the neolithisation processes of N Hungary, Slovakia (Hurbanovo and Biňa, Košice-Červeny Rak a.s.o.) and E Austria (Prellenkirche a.s.o.) is related with the evolved phases of SC culture (Zăuan, Tăşnad – Sere). Neolithic sites located in area of salt sources of Someş and Tisa basins prove also ethno-cultural exchanges (obsidian import of NE Hungary, SW Slovakia and maybe other).

Abstract Background: The beneficial effects of long-chain n-3 fatty acids (LC-n-3 FA) of marine origin on lipids and cardiovascular events are well documented. However, the relevance of plant-derived C18-n-3 FA (alpha-linolenic acid, ALA) on atherogenesis and on arachidonic acid (AA, the proaggregatory precursor of thromboxane) remains unclear. Furthermore, the capacity for chain elongation is thought to be minimal in mammals. We have reported on the potential benefits of increased concentrations of ALA in alpine milk products (“The alpine paradox”). Aims: We tested if an ALA-rich diet reduces atherosclerosis, induces a favorable lipid profile including a reduced content of AA in red cell membranes, liver and adipose tissue, and promotes chain elongation of ALA into LC-n-3 FA. Methods and Results: Eight weeks old male apolipoprotein E knockout (ApoE− /−) mice were fed a 0.15% cholesterol diet for 16 weeks containing either a high ALA (high, 7g/100g; n=10) or a low ALA content (low, 0.03g/100g; n=10). ALA was given as flaxseed oil, the control diet was compensated with cocoa butter. Plaque area in the aortic arch as quantified by oil-red O staining was reduced by 53% (P<0.05) in the high ALA group. Furthermore, T cells, expression of VCAM-1 and TNF-α in plaques were all diminished in mice fed a high ALA diet (P<0.05). Weight gain was similar in both groups. The content of LC-n-3 FA in red cell membranes, liver and adipose tissue was analyzed by gas chromatography and given as FA percentage (Table). The high ALA diet induced a marked increase in ALA incorporation in all tissues. In addition, we found a 5x shift in the red cell LC-n-3 FA (EPA, DPA, and DHA) content a measure of chain elongation which was even 7x in the liver. Adventitial adipose tissue contained higher concentrations of LC-n-3 FA than the subcutaneous or the perirenal fat. In addition, ALA strongly reduced AA in various tissues: We found an almost 5- fold reduction in in red cell AA and the liver samples contained less than half of the AA content. The differences in adipose tissues were less pronounced. Conclusions: A diet rich in ALA decreases atherosclerosis, T cells and the expression of VCAM-1 and TNF-α in ApoE−/− mice. These beneficial findings are associated with a favorable FA profile (increased chain elongation into LC-n-3 FA) and reduced AA in red cells, liver, and adipose tissue. Given the limited fishery resources, plant-derived ALA may represent an attractive nutritional supplement with atheroprotective and anti-inflammatory effects.

Full textAbstract:
Mountain lakes, typical signs of an alpine landscape all around the world, were formed in the western part of the Carpathian Arch about 10,000-15,000 years ago, as remnants of the last continental glaciation. In the Tatra Mountains (Slovak-Polish border), more than 110 permanent lakes of glacial origin and many other small ponds exist. These (sub)alpine lakes, with their specific conditions, are very vulnerable and any change in their environment can largely impact their biodiversity, which is, despite long-term faunistic and ecological research, still not fully recognized. This shortcoming could be strongly improved by molecular approaches, which, even within population-genetic studies, often reveal unsuspected cryptic lineages or potential new species. Our long-term research is aimed at revealing the genetic diversity of aquatic macroinvertebrate species in the alpine environment of the Western Carpathians. One of the currently studied species is the glacial relict flatworm taxon Crenobia alpina (Dana, 1766) (Tricladida: Planariidae), representing an element of the permanent aquatic fauna. Totally, 88 COI haplotypes of C. alpina forming at least five well-separated genetic lineages were identified within 348 individuals collected from 45 lakes and ponds in theTatra Mts. Based on tests of selective neutrality and population stability, C. alpina populations in the Tatra lakes did not overcome recent population expansions or contractions. It seems that great genetic differences between localities and their population stability could be a consequence of the presence of natural topographic barriers (ridges, mountain peaks) dividing the mountains into small and relatively isolated valleys. Moreover, other important factors that could play a significant role are the limited dispersal ability of the species as well as its ability to reproduce asexually. Our findings were also compared with all publicly available sequences (Barcoding of Life Datasystems - BOLD and GenBank) in order to shift our data from a local to a holistic view on C. alpina. Our resultssupport the assumption of Brändle et al. 2017 that C. alpina represents a complex of cryptic lineages or species in Europe. As part of the AquaBOL.sk initiative, the data obtained contribute to the knowledge of genetic variability and barcoding of aquatic organisms in Slovakia.
