    Klizište u zoni mosta Slobode u Novom Sadu je jedno od najviše istraživanih klizišta u Srbiji iz razloga što predstavlja ozbiljnu prijetnju po stabilnost pomenutog mosta preko Dunava. U vrijeme završetka izgradnje 1981. godine, ovaj most s kosim kablovima, bio je na svijetu s najvećim središnjim rasponom od 351 m. U tijelu klizišta, most je temeljen na armiranobetonskim pilotima duljine 27 m. Utvrđena dubina pomicanja za prvi klizni blok iznosi 26 m, a za drugi 35 m. Projektirani drenažni sus...

    Full Text Available This article focuses on a commodity flow model for an exclave region (CFMER. The CFMER development is aimed at identifying aggregate proportions of the exclave’s economy in the transitional period of the special economic zone (SEZ functioning. The key method of analysis is the comparison of data on the generation of gross regional product and regional foreign economic activities (including export and import of goods and moving goods from/into the Kaliningrad region to other Russian regions. It results in a conceptual CFMER, which is assessed as of 2011. The availability of additional — as compared to a regular region — data on commodity flows in the framework of the SEZ transitional period makes it possible to identify structural disproportions in the economy. It is shown that the introduction of the SEZ transitional period did not result in a change in the conceptual model of the regional economy’s functioning merely increasing the opportunities for rent extraction. The authors predict structural imbalances in the exclave economy at the microlevel, in particular, the article analyses the conceptual model of rent extraction in the SEZ transitional period. The CFMER can be used for forecasting the development of exclave’s economy under different scenarios of the evolution of SEZ in the Kaliningrad region.

  3. Model of the hydrodynamic process of modifying different rocks in near-face zone. Model' gidrodinamicheskogo protsessa vozdeystviya na razlichnyye porody prizaboynoy zony

    A mathematical modal is presented for the hydrodynamic process of modifying the pressure pulse of rocks with different reflecting properties. It can be used to control both stripping of the bed, and to prevent emergency situations of the oil seal formation type. This hydrodynamic process is described by a nonlinear system of differential equations. The boundary conditions are the condition of reflection of the conducting flux by the rocks with different coefficients of reflection (dissipation of the stream energy). Results are presented from calculation on the computer YeS-1020 for drilling strings 1,000 m long and 3,000 m for rocks with coefficients of reflection K=0.001-0.1.

    U ovom radu pružili smo pregled spoznaja o neurobiološkoj osnovi poremećaja migracije koja je važna za njihovu klasifikaciju. Kortikalni neuroni rađaju se u ventrikularnoj i subventrikularnoj zoni te prolaze dugačak put do svojeg konačnog odredišta, rabeći dva osnovna mehanizma i puta migracije: (1) radijalnu migraciju, put uzduž radijalne glije i (2) tangencijalnu, najvjerojatnije “neurofilnu” migraciju. Tijek migracije je složen i može biti poremećen utjecajem različitih genetskih i vanjski...

    This research reports the preliminary results of a study based on the SOC (Soil Organic Carbon) fractionation in a pine forest soil (Pinus nigra). Hyperskeletic Albic Podzol soil (P113005, World Reference Base, 2014), described by the following sequence O-Ah-E-Bh-Bs-Cg, was investigated at Zoniën, Belgium. Total (TOC) and extractable (TEC) soil contents were determined by Italian official method of soil analysis. Different soil C fractions were also determined: Humic Acid Carbon (HAC) and Fulvic Acid Carbon (FAC). Not Humic Carbon (NHC) and Humin Carbon (Huc) fractions were obtained by difference. Along the mineral soil profile, therefore, were also tested some enzymatic activities, such as cellulase, xylanase, laccase and peroxidase, involved in the degradation of the main organic substance components, and dehydrogenase activity, like soil microbial biomass index. The results shows a differential TEC fractions distribution in the soil profile along three fronts of progress: (i) An E leaching horizon of TEC; Bh horizon (humic) of humic acids preferential accumulation, morphologically and analytically recognizable, in which humic are more insoluble that fulvic acids, and predominate over the latter; (ii) horizon Bs (spodic) in which fulvic acids are more soluble that humic acid, and predominate in their turn. All enzyme activities appear to be highest in the most superficial part of the mineral profile and decrease towards the deeper layers with different patterns. It is known that the enzymes production in a soil profile reflects the organic substrates availability, which in turn influences the density and the composition of the microbial population. The deeper soil horizons contain microbial communities adapted and specialized to their environment and, therefore, different from those present on the surface The results suggest that the fractionation technique of TEC is appropriate to interpret the podsolisation phenomenon that is the preferential distribution of
