SynopsisA front on the Great Plateau separates tidally mixed water of the North Channel from quieter less saline surface layers of the Outer Firth. These water bodies exchange about 1·6 × 104m3 s−1, leading to a residence time of two months in the Outer Firth surface layers. The position of the front is determined by the balance of mixing and buoyancy supply. The wind modulates weak tidal currents in the Outer Firth by driving surface currents and setting up deeper compensation flows. Deep water in the Arran Deep and Kilbrannan Sound is irregularly renewed by inflow of dense water over the Eastern Plateau from autumn to spring of about 1 × 104m3 s−1 but stagnates in summer below a thermocline. A minor part of this renewal comes over the Davaar sill into Kilbrannan Sound.Bottom water of the fjordic sea-lochs is isolated in summer and renewed during the winter. The renewals occur by density currents flowing in from the sills and these produce a characterising grading of the bottom sediments from coarse to fine away from the sills.

Abstract The research was conducted from August until November 2012 in the districts of Moldavia (Botoşani, Suceava, Iaşi, Vaslui, Bacău, Neamţ, Galaţi and Vrancea), in the West and the Central part of the country (Cluj and Covasna districts) and in the South-East of the country (Tulcea and Brăila districts). The choice of the districts was established based on the informations received from Animal Improvement and Breeding Offices in Romania. The purpose of this research was to identify the effective of Sura de stepă cattle breed in Romania and the evaluation of the phenotypic characters in steppe animals, which belong to the variety of Moldavian breed. The results showed that the Sura de stepă breed consists of a minor part, being raised in just two districts of Moldavia, Iaşi and Neamţ, respectively, as a pure breed with an average of 0,03 % (83 cows), at the Research and Development Station for Cattle Breeding (R.D.S.C.B.) Dancu-Iaşi, with a core of preservation of 59 cows (0,19 %) and at the Holding TCE 3 Brazi Society, Neamţ district, with a core of 24 cows (0,06 %), and under half-breed form with an average of 0,33 % (592 cows). In Harghita, Covasna and Cluj districts, 295 cows from the Sura de stepă breed, Hungarian variety, were identified, excepting being the animals belonging to University of Agricultural Sciences and Veterinary Medicine Cluj, which come from R.D.S.C.B. Dancu-Iaşi, which are Romanian Sura de stepă, Moldavian variety. In Tulcea district, 20 cows of half-breed Sura de stepă and 50 cows of pure breed cattle, Moldavian variety, were identified, from which 24 cows at a private landlord in Pardina locality, Tulcea district, and 26 cows belonging to nine owners from different localities (C.A. Rosetti, Pardina, Chilia Veche, Sfântu Gheorghe, Crişan), each owning 2-3 cows. The analysis of the main body indices showed that the Sura de stepă cows from Pardina, Tulcea county, are of small size and weight, having smaller values in all analysed parameters, compared to the Sura de stepă cows from R.D.S.C.B. Dancu-Iaşi from the North-East part of the country, which however fitted the specific limits of the breed, Moldavian variety.

<p>A scientific drilling was conducted into a bedrock trough in Bern-Bümpliz, a branch of the Aare Valley overdeepening (Switzerland). It is the first scientific drilling in the Bern area that reached the bedrock. We analyzed the 208.5 m-thick succession of Quaternary sediments recovered in this scientific drilling and present the sedimentological results of the campaign. In the retrieved sediments 12 different lithofacies were identified, which were grouped into 5 facies assemblages, and 2 major sedimentary sequences (A = lower, B = upper), which transition into a minor sequence C. Generally, the sedimentary successions of sequences A and B are similar. The lowermost facies assemblage of each sequence consists of a till that was deposited during a period of ice cover. However, the two tills differ from each other. In particular, while the till at the base of sequence A is dominated by large clasts derived from the underlying Molasse bedrock, the till at the base of sequence B has no such Molasse components. Furthermore, the till in sequence A bears evidence for glaciotectonic deformations. Both tills are overlain by thick facies assemblages of subaqueous, most likely glaciolacustrine and lacustrine sediments. Sequence A is characterized by cross-bedded and steeply inclined sand, gravel and diamictic beds which we interpret as deposits of density currents in a subaqueous ice-contact fan system in a proglacial lake. In contrast, the lacustrine sediments in sequence B are considered to record a less energetic environment where the material was most likely deposited in a prodelta setting that gradually developed into a delta plain. Towards the top, sequence B evolves into the fluvial system of sequence C, where large sediment fluxes of a possibly advancing glacier resulted in a widespread cover of the region by a thick gravel unit. Additionally, feldspar luminescence dating was performed on two samples from a sand layer at the top of sequence B. The dating in combination with lithostratigraphic correlations with the sequences encountered in the neighboring scientific drillings to the north (Meikirch) and south of Bern (Thalgut) suggests that sequence B was deposited during Marine Isotope Stage 8 (MIS 8; 300–243 ka).</p>

During the summer af 1979 the Geodetic Institute, Copcnhagen, continued the North Greenland survey, which was initiated in 1978 (Forsberg, 1979). This comprised establishment of ground control points by help of Doppler instruments combined with barometric, triangulation and doppler-derived heights as vertical control. During 1979, as a minor part of the surveying programme, a regional gravity network was established for the area belween Hall Land and Nansen Land (fig. 66).

The article explores the role of antropoetonyms in the reader’s “horizon of expectation” formation. As a kind of “text in the text”, antropoetonyms are concentrating a large amount of information on a minor part of the text, reflecting the main theme of the work. As a “text” this class of poetonyms performs a number of functions: transmission and storage of information, generation of new meanings, the function of “cultural memory”, which explains the readers’ “horizon of expectations”. In analyzing the context of the literary work we should consider the function of antropoetonyms in vertical context (the link between artistic and other texts, and the groundwork system of culture), as well as in the context of the horizontal one (times’ connection realized in the communication chain from the word to the text; the author’s intention). In this aspect, the role of antropoetonyms in the structure of the literary text is extremely significant because antropoetonyms convey an associative nature, generating a complex mechanism of allusions. It’s an open fact that they always transmit information about the preceding text and suggest a double decoding. On the one hand, the recipient decodes this information, on the other – accepts this as a sort of hidden, “secret” sense.

The relative enthalpies of proton transfer δ ΔH0and homolytic bond strengths δDH0(B-H+) were calculated by the MNDO method for the sp and ap conformers of 4-flurobutylamine. The data obtained, along with the experimental gas phase basicities, are compared with the values predicted by the electrostatic theory. It is shown that the substituent polar effects FD on the basicities of amines are predominantly due to interactions in their protonated forms (X-B-H+) and/or radical-cations (X-B+.), those in the neutral species (X-B) playing a minor part. A contribution, which is considerably more significant in the sp conformer than in the ap conformer, arises probably also from substituent effects on the homolytic bond strength DH0(B-H+.

In this study, petrological, structural, geochemical, and geochronological analyses of the Statherian alkali feldspar granite and porphyritic alkali feldspar granite in the southwestern part of the Korean Peninsula were conducted to examine petrogenesis of the granitoids and their tectonic setting. Zircon U-Pb dating revealed that the two granites formed around 1.71 Ga and 1.70–1.68 Ga, respectively. The results of the geochemical analyses showed that both of the granites have a high content of K2O, Nb, Ta, and Y, as well as high FeOt/MgO and Ga/Al ratios. Both granites have alkali-calcic characteristics with a ferroan composition, indicating an A-type affinity. Zircon Lu-Hf isotopic compositions yielded negative εHf(t) values (−3.5 to −10.6), indicating a derivation from ancient crustal materials. Both granite types underwent ductile deformation and exhibited a dextral sense of shear with a minor extension component. Based on field relationships and zircon U-Pb dating, it was considered that the deformation event postdated the emplacement of the alkali feldspar granite and terminated soon after the emplacement of the porphyritic alkali feldspar granite in an extensional setting. These data indicated that there were extension-related magmatic activities accompanying ductile deformation in the southwestern part of the Korean Peninsula during 1.71–1.68 Ga. The Statherian extension-related events are well correlated with those in the midwestern part of the Korean and eastern parts of the North China Craton.

Dietary studies based on 24 h recalls were carried out on four oil installations in the Norwegian sector of the North Sea. Two hundred and three persons were interviewed about what they had eaten the previous 24 h. Food purchased for the installations in the previous 5 months was recorded. Results based on 24 h recalls showed that average daily intake of energy was 12.2 MJ of which 17% came from protein, 44% from fat and 39% from carbohydrate, including 8% from sugar. Meat, vegetables, fresh fruits, seafood (shellfish), french fries, eggs, cream and ice-cream were important components of the diet, while bread, fish and cereals played a minor role. Average daily intake (mg) of nutrients were: calcium 1244, iron 15, vitamin A 1049 μg, vitamin D 4.1 μg, thiamin 1.6, riboflavin 2.2, nicotinic acid 22, ascorbic acid 143. Dietary fibre intake, estimated as unavailable carbohydrate, was on average 19 g, and the average daily intake of cholesterol was 755 mg. Intakes were compared with the Norwegian recommended dietary allowance. Most of the employees chose a diet which when eaten over a longer period of time may contribute to the development of coronary heart diseases (CHD) and thereby increase the morbidity and mortality from CHD in the oil industry.

AbstractThe formation of Saturn and its disk is simulated using a new N-body self-gravitational model. It is demonstrated that the formation of the disk and the planet is the result of gravitational contraction of a slowly rotated particle cloud that have a shape of slightly deformed sphere. The sphere was flattened by a coefficient of 0.8 along the axis of rotation. During the gravitational contraction, the major part of the cloud transformed into a planet and a minor part transformed into a disk. The thin structured disk is a result of the electromagnetic interaction in which the magnetic forces acting on charged particles of the cloud originate in the core of the planet. The simulation program gives such parameters of Saturn as the escape velocity of about 35 km/s at the surface, density, rotational velocities of the rings and temperature distribution.

Sharks and rays are a global conservation concern with an increasing number of species considered at risk of extinction, mostly due to overfishing. Although the recreational harvest of sharks and rays is poorly documented and generally minimal, it can be comparable to the commercial harvest. In this study, we quantified the recreational harvest of sharks and rays in Western Australia, a region with a marine coastline greater than 20,000 km. A total of 33 species/taxonomic groups were identified, with the harvest dominated by dusky and bronze whalers, blacktip reef sharks, gummy sharks, Port Jackson sharks, wobbegongs, and rays and skates. Eighty-five percent of individuals were released with an unknown status (alive or dead). We found a latitudinal gradient of species composition, with tropical and subtropical species of the genus Carcharhinus dominating in the north and temperate species from a range of families dominating in the south. Overall, our findings showed that the recreational harvest was negligible when compared with commercial landings.

Purpose: Determination of the peculiarities of the behavior and the flow of childbirth in females (wrenches) of the northern home deer of the Even Breed of the Republic of Sakha (Yakutia), depending on the natural climatic zone of breeding.Material and research methods. Research of the reservation of the hotel's reservoir of the northern home deer was held from April to June in the reindeer herds of the mountain-taiga (FSUE «Yuchjuyuskoye») and the Tundrov zones (SHPZK «Taba-Yana») of the Republic of Sakha (Yakutia) in the conditions of nomadic home reindeer herding since 2013 2018 In the study, the method of observation is used with the registration of motor activity of animals and the activities of individual bodies in a certain living environment.Results. To fix some patterns and species features of the generic process, 8 main elementary behavioral reactions spent venizables of northern domestic deer per day before childbirth: walking, feeding feed, chewing, leisure standing, rest lying, sleep, urination (how many times / total time), defecation (how many times / total time). Also marked 4 behavioral reactions on the hotel day: the exploitation time of the fetus, the licking of the calf, the time of the calf on his feet after delivery, the first reception of the mosper calf after birth. For each parameter, data reflected in tabular format is obtained.Conclusion. It has been established that the degree of adaptation of the northern domestic deer to the harsh conditions of existence in various natural-climatic zones of the Republic of Sakha (Yakutia) is very high, which is manifested in a minor difference in the duration of the generic process and behavioral reactions at the vainer of the mountain and tundra and tundra dilution zones.
