Opis:
Pliocene fish species based on skeleton remains and associated teeth ever reported from the inner Carpathian area in Romania in the Braşov Basin (Baraolt sub-basin), which refers to a pike (Esox sp.). The fish fossils illustrating a large-sized specimen originate from the South Racoş coal open pit (Racoşu de Sus, Covasna County), in the so-called “Formation with Limnocardium” (Dacian, Lower Pliocene). Comparisons with osteological material of recent pikes originating from various localities in Romania are presented. The associated mollusc fauna known from the formation that yielded the pike remains suggests the presence of a lake with a stratified water column in the Baraolt sub-basin.

Opis:
In this paper the authors describe the steps of building of a new automated complex land evaluation system based on the D-e-Meter land quality index. Complex evaluation means an organic systematization of ecological and economical factors. Necessary of development of a new land evaluation system based on the undeveloped land market in Hungary, which causes difference between the level of actual land price and economic value of agricultural land. The land evaluation has - among others - an important task: that is to convey the value towards the land market actors, which can be the starting point in negotiation about market price and in decision-making about the land use. The estimated land value indicates the total values of land estates on the basis of their rent-production ability. These values can differ from land-estate prices formed on land market, nevertheless they are decidedly adequate to replace the Hungarian current land evaluation system, so called Gold- -crown System and to solve whole series of objectives connected with land evaluation. The new land evaluation system is useful for estimating the realistic land value, but also helps to manage the land use on sustainable way.

Opis:
Agricultural land market in Hungary is in process of development, the prices of land is times lower compared to land prices in old member states of the EU. Because of their lower income Hungarian nationals do not have substantial possibilities to acquire ownership over land like nationals of the old member states of the EU. In order to preserve the agricultural sector from shocks that might arise from the differences in land prices and income with the rest of EU, Hungary as the others Central and Eastern European new member states countries (the Czech Republic, Estonia, Latvia, Lithuania, Poland and Slovakia) during the accession negotiations in 2003 was granted the possibility to maintain existing national provisions restricting the acquisition of agricultural land or forests. Based on the data provided by the Hungarian Farm Accountancy Data Network and by the Hungarian Central Statistic Office the authors examined the specific impacts of factors influencing on arable land prices.

The submitted article deals with the issue of the application of the PVD coating nACRo4 deposited on the High Contact Ratio gearing made of 16MnCr5 material in interaction with the conventional PP 90H lubricant and biological Biogear S150 lubricant. Experimental tests were carried out on an FZG test rig with closed performance flow, followed by measuring of the surface roughness change. In experiment, we followed the STN 65 6280 norm for FZG scuffing tests, from which we gained load values for different load levels. The results of experimental tests were statistically processed and, on basis on them, relations were established between surface roughness and load level for both used lubricants.

Opis:
Laughter is one of the most important paralinguistic events, and it has specific roles in human conversation. The automatic detection of laughter occurrences in human speech can aid automatic speech recognition systems as well as some paralinguistic tasks such as emotion detection. In this study we apply Deep Neural Networks (DNN) for laughter detection, as this technology is nowadays considered state-of-the-art in similar tasks like phoneme identification. We carry out our experiments using two corpora containing spontaneous speech in two languages (Hungarian and English). Also, as we find it reasonable that not all frequency regions are required for efficient laughter detection, we will perform feature selection to find the sufficient feature subset.

Opis:
Providing the population with safe and good quality food is one of the most important objectives of every country. The outbreak and spread of foodborne diseases is independent of a country’s location or development level, and may occur everywhere. As most children spend their days at educational institutions, we shall focus on their food safety. Not only for their present state of health, but also because childhood nutrition and diet will basically determine their health in their adulthood and thus, influence the future economic and social performance of their society. This paper introduces background information about school catering in Hungary, based upon the results of an overall food safety survey. The results of our research showed that the food safety level of the different kitchen units is mostly determined by the level of food processing activities. The technical and technological level of the school kitchens did not significantly influence the food safety level of the kitchens. According to the results of our survey, improving the knowledge and the attitudes of employees in school kitchens is more important than technical and technological conditions.
W pracy przedstawiono informacje na temat żywienia w placówkach szkolnych na Węgrzech, oparte na wynikach ogólnej ankiety dotyczącej bezpieczeństwa żywienia. Zapewnienie ludności bezpiecznej żywności o dobrej jakości jest najwyższym priorytetem każdego kraju. Ponieważ większość dzieci spędza swoje dzieciństwo w placówkach dydaktycznych należy skupić się na bezpieczeństwie serwowanej w nich żywności. Nie tylko ze względu na obecny stan zdrowia dzieci, ale również dlatego że odżywianie w znacznym stopniu determinuje zdrowie młodych ludzi, co wpływa na przyszłe osiągnięcia ekonomiczne i socjalne danej społeczności. Wyniki badania wykazały, że poziom bezpieczeństwa żywienia w różnych stołówkach zależaqł przede wszystkim od poziomu przetworzenia żywności. Poziom techniczny i technologiczny kuchni szkolnych nie wpłynął w znaczący sposób na poziom bezpieczeństwa żywności w nich przygotowywanej. Zgodnie z wynikami ankiety, zwiększanie wiedzy i świadomości pracowników szkolnych kuchni było ważniejsze niż warunki techniczne i technologiczne.

Opis:
Carpathian Scots pine populations having peripheral distribution within the species’ range are often sustained in specific types of habitats, such as peat bogs and rocky surfaces or lime consisting sandy substrates. Due to their long time adaptive processes, which involve genotypes that can be preadapted to a given selection pressure, historically isolated populations are subjects of particular interest in studies of in situ adaptation. In this study we focus on detecting the level of phenotypic differentiation based on cone morphology and needle anatomy in marginal populations of Pinus sylvestris L. in the Pannonian Basin and the Carpathian Mountains. Six cone morphological and eight needle anatomical characters were measured and four cone morphological and four needle anatomical ratios were calculated. Our results in concordance with paleobotanical data indicate a common origin of the populations from the Northern Carpathians and the Pannonian Basin. High levels of variation were observed in cone morphology. Discriminant function analysis based on the eight cone characteristics revealed clearly discernible groups of populations and indicated significant differentiation among populations growing in peat bogs and on rocky substrates. Significant differences among populations from different habitats were also revealed by comparing needle anatomical variables. The phenotypic differentiation by habitat type based on the measured characters might be evaluated as a sign of local adaptation with detectable phenotypic patterns.

The influence of the inclusion of the dodecanethiol functionalized gold particles (with diameter 3-5 nm) on the structural transitions was investigated. The studied samples were based on the nematic liquid crystal 4-(trans-4'-n-hexylcyclohexyl)-isothiocyanatobenzene (6CHBT). The volume concentration of the gold particles was $ϕ_1 = 2 × 10^{-4}$ and $ϕ_2 = 10^{-3}$. The obtained results showed that the inclusion of the gold particles in the 6CHBT liquid crystal increases the sensitivity of such system on the external magnetic field.

Opis:
The main purpose of the paper is to present the relations between the different cost factors of the inventory management systems, and the context between the order quantities and the cost level. The theoretical approach of the model assumes a deterministic operational environment with planned shortages. We make the examination of the contexts by applying the ceteris paribus principle; we change only one cost factor from among the initial conditions at once and examine its effect on the cost level. By using the economic order quantity with the planned shortage model, we can define the optimal order quantity, along which our stock management can be guaranteed by the most favourable cost level. The optimisation of the inventory level and the inventory management expenses together means an important factor in the competitiveness of the company. During the definition of the optimal inventory level of purchased parts, the purchasing and stock holding costs, and also the consequence of shortages play an important role. The presentation of the specific expense factors in each other’s function, and the representation of the onetime order expenses show their proportion compared to each other and the effect of their change on the total cost, and define the opportunities of the optimisation. The significance of the model is that it represents the level line of costs, the movement of the different cost factors in relation to others and their operating mechanism. Thus, it facilitates the representation of costs and the definition of the direction of optimisation.

The objective of the logistics management is to guarantee the stock level required for the adequate handling of production at the lowest possible level of costs and risks. The main purpose of the paper is to present the relations between stock level and risk of shortages. As a result of the research, the introduction of the safety stock is the solution to cover the effects of the uncertain factors in the supply chain. The theoretical approach of the model assumes a deterministic operational environment, in practice, however, there are several unpredictable factors influencing the operation of the production company. By using the periodic and continuous review models, the paper presents the effects of demand changes and stochastic length of replenishment time on the risk of stock availability. We need to quantify a service level which determines the accepted probability of the shortage occurrence.

Opis:
In this work, the influence of recoil effect and surface excitations on the inelastic mean free paths for polythiophenes is investigated. The inelastic mean free paths of electrons in polythiophenes are measured with the elastic peak electron spectroscopy method using the Ag standard and the electron elastic scattering cross-sections from the database NIST 3.1 in the electron kinetic energy range 200-5000 eV. The Monte Carlo model is applied for evaluating the electron backscattering intensities from the polymers and the Ag standard, as well as for evaluating electrons quasi-elastically backscattered from atoms of different atomic numbers (the recoil effect). The surface excitation corrections are accounted for using the formalism of Chen, with the material parameters for polythiophenes evaluated from the elastic peak electron spectroscopy method. Deviations due to recoil effect and surface excitations to the inelastic mean free paths are compared and discussed. Correction to the inelastic mean free paths due to recoil effect is considerable but is smaller, however, than the correction due to surface excitations. Accounting for recoil effect and surface excitations leads to improvement of the inelastic mean free paths, as compared to the inelastic mean free paths resulting from the predictive formulae of Gries.

Opis:
The aim of this paper was to show how the shape of sand particles affects the results of particle size distribution obtained by the laser diffraction method. On the basis of the results obtained one can conclude: the shape of the investigated particles influences particle size distribution obtained by the laser diffraction method. This phenomenon occurs in the sand fraction, as shown in our investigation. The importance of this effect depends on the type of the measured material and on the aim of the investigations. For most researchers in soil science and sedimentology who investigate sand fractions, this impact can be negligible. Further investigations with other soil and sediment fractions are needed.

Opis:
Depending on the preparation and the applied materials, moulds and cores can be of high rigidity or can be flexible. Although, chemically bonded moulding materials have relatively good flexibility, their high temperature behaviour determines the dimensional accuracy, the stresses in the castings and can induce several casting defects, such as rattail, veining, etc. The phenomenon is based on two major effects: the thermal expansion of the unbonded foundry sands and the deformation of the sand mixtures. The main objective of the present work was to study the relationship between these two effects, and to improve the knowledge related to the thermo-mechanical interactions between the casting and the mould. Dilatometric analysis of unbonded sand samples were performed and compared to the results of hot distortion tests of moulding mixture specimens. The results showed, that the thermal expansion of foundry sand largely influences the hot distortion behaviour, but depending on the type of binder used.

In this work we describe the magnetic Freedericksz transition in HAB-based (4, 4'-di-n-heptylazoxybenzene) ferronematics. The ferronematic samples were prepared with two different volume concentrations of magnetic particles $φ_1 = 2×10^{-5}$ and $φ_2 = 2×10^{-4}$. The liquid crystal HAB is nematic at the temperatures from ≈53°C to 70°C and smectic A at the temperatures under 53°C. The anisotropy of dielectric permitivity of HAB liquid crystal is positive in nematic phase and negative in smectic A phase. The magnetic Fredericksz transition was studied in nematic phase at temperature 60°C.
