Biogas Production Based On Miscanthus × Giganteus (Miscanthus Sinensis Anderss.) Within Dry Fermentation Process
Authors: Porvaz Pavol , Gaduš Ján , Tóth Štefan , Jóvér János 
Published: May 2018

Abstract
“Dry fermentation“ technology may be used for energy recovery of phytomass substrate which has dry matter content from 20 to 60%. In agriculture sector, while only rarely used, it is a very perspective technology at such types of biomass – phytomass which is not recommended to be processed within “wet fermentation” (process is energetically and operationally very costly). For detecting the suitability of Miscanthus × giganteus phytomass to biogas for production through dry fermentation process, as well as determining the biogas yield, at the Slovak university of Agriculture (SUA) there has been developed an experimental device enabling the pilot plant trials, which is installed at the biogas station within the area of the VPP SPU Ltd. in Kolíňany. A pilot plant experiment of biogas production based on Miscanthus × giganteus (Miscanthus sinensis Anderss.) phytomass within dry fermentation process was carried out at the period from 25 February to 25 March 2013. The monitored production of biogas was based on the substrate mixture of components formed as follows: the biomass from preceding cycle (farmyard manure) and ensilage from Miscanthus phytomass. In these experiments the amount of produced biogas, analysis of biogas and the input substrate were materialized by standard methodology. On base of the obtained results, we can formulate the conclusion: the tested substrate mainly consists of Miscanthus phytomass and manure was suitable for biogas production technology and anaerobic dry fermentation process. The yield of Miscanthus substrate in our experiments was around 117 litres of biogas per 1 kg of dry matter silage. For assurance of the continuity and uniformity in the production of biogas by dry fermentation process, the multiple-fermentation chamber is needed, which must be saturated gradually with dosing interval. This dosing interval is caused by residence time and the number of chambers. For example, at the residence time of 28 days and 4 chambers, the need of the substrate change will be on weekly base in each chamber.
Influence of Cow Dung Application on the Yield and Yield Components of Two Groundnut (Arachis hypogaea L.) Varieties in Sokoto, Semi-arid Zone of Nigeria
Authors: Musa Mukhtar , Singh Ajit 
Published: May 2018

Abstract
Groundnut (Arachis hypogaea L.) is a valuable crop for millions of small scale farmers around the tropics. Despite its importance, the production of the crop in semi-arid tropics is constrained by shorter rain duration and low soil nutrient status. The present studies was carried out during the 2007 and 2008 rainy seasons to study the influence of cow dung application on the yield and yield components of two groundnut varieties in the region. Treatments consisted of factorial combination of two groundnut varieties (Ex-Dakar and RMP-12) and three cow dung levels (0, 15 and 30 t ha−1) making a total of six treatment combinations. The treatments were laid out in a randomized complete block design replicated three times. The findings of this research revealed that Ex-Dakar variety performed better than RMP-12 in all the parameters measured. Application of cow dung increased the number of pods plant−1, pod yield and grain yield of the crop and was optimum at the rate of 15 t ha−1. Thus, Ex-Dakar variety could be suggested for increased groundnut production in the study area. Application of cow dung at the rate of 15 t ha−1 was optimum for groundnut production in the study area.

Abstract
In this paper, yoghurts from ultrafiltered concentrated whole milk with a volume reduction ratio 0, 2 and 3 with three different probiotic yoghurt starters were obtained. Their physiological, microbiological and rheological properties were examined. The concentrated probiotic yoghurts had high concentration of viable cells of the probiotic strain Lactobacillus delbrueckii ssp. bulgaricus (over 1010cfu/cm3). For the preparation of concentrated probiotic yoghurts the most appropriate volume reduction ratio was 2. The probiotic yoghurts with starters MZ2 and 1CM had the best structure. The concentrated probiotic yoghurts with all starters are functional foods.
Influence of Tool Balancing in High Speed Machining
Authors: Bašovská Klaudia , Peterka Jozef 
Published: May 2018

Abstract
The high speed machining (HSM) is now considered as one of the key manufacturing technologies for higher throughput and productivity. HSM used higher rotational speed of the spindle (40,000 min-1 and higher). With increasing high speed spindle rotations raises a number of dynamic forces. Even a small mass unbalance in the spindle and tooling generates tool vibration. Tool vibration shortens tool life and lowers the quality of the machined surface. It is necessary to minimize this vibration by balancing tool and tool holder. The balancing process improves the mass distribution of a cutting tool and its holder, allowing the combination of the two to rotate with the minimum amount of unbalanced centrifugal forces. Machining with balanced tool will provide better surface quality, accuracy and less tool and machine wear. In this study is focused on unbalance cutting tools, definitions, balancing techniques, sources, effects, processes and machineries. The aim of this article was to examine the relationship between unbalance and tool holders used in high speed metalworking machine tools

Authors: Vulc Silvia 
Published: May 2018

Abstract
This paper presents a study on grinding tungsten carbide DK460UF, through experimental investigation using diamond grinding wheel with 54 μm grain size. Different sets of experiments were performed to study the effects of the independent grinding parameters such as grinding wheel speed, feed and depth of cut on cutting forces. Test results showed that the feed and depth of cut influence significantly the cutting forces. The research was lead to optimize the process parameters for reducing cutting forces. In this way, for different parameters of cutting regime, it were measured the values of the components of the grinding force, tangential component, Ft and normal component Fn. The results of the experiment showed that it is better to use great speeds and small feed rate and depth of cut in grinding tungsten carbides, such as DK460UF
Identification of new superwarfarin-type rodenticides by structural similarity. The docking of ligands on the vitamin K epoxide reductase enzyme’s active site
Authors: Ferencz László , Muntean Daniela Lucia 
Published: May 2018

Abstract
The rodenticide brodifacoum is highly toxic to mammals and birds, and extremely toxic to fish. It is a highly cumulative poison due to its high lipophilicity and extremely slow elimination. For this reason, it may be interesting to find similar compounds in order to enlarge the spectrum of vitamin K epoxide reductase enzyme inhibitors used today in pest control. We used the Similar Compounds search type of the Chemical Structure Search of the PubChem Compound Database to locate records that are similar to the chemical structure of brodifacoum, using pre-specified similarity thresholds. Using the threshold ≥ than 95% for the similar structures criteria, we found 14 compounds (from over 30 million entries) that meet this criteria. Two of these compounds have a better binding affinity to vitamin K epoxide reductase enzyme than brodifacoum, but the binding energy of the other 12 substances is also high, having identical or lower lipophilicity; consequently, they will eliminate faster, possibly lacking a part of the adverse effects.
A historical survey of the Corunca Castle, Romania, based on the military survey maps and present-day measurements
Authors: Kovács Lóránt 
Published: May 2018

Abstract
Corunca is situated at 4.5 km SE from Târgu-Mureș, near the Salt Stream, the Bozeni Stream, and the Vațman Stream. Its area is inhabited from ancient times. Both prehistoric and Roman findings were reported to have been found within the village boundaries. Its neighbouring medieval village, Sárvári, perished in the 16th century, while Kisernye was devastated by Turkish troops in 1661. The settlement was first recorded in 1332 as Korunka. The Reformed Church was built between 1769 and 1778, while its spire dates from 1793. The earlier church was surrended by high protective walls, which were demolished in 1769.
The extremely ruinous castle with its neoclassical façade and a couple of neighbouring farm buildings appear on the left side of the European route E60 travelling from Târgu-Mureș to Sighișoara. Today, this is a barren place, although once it was surrounded by a grove the size of 120 cadastral acres [2].
During the reign of John Sigismund Zápolya, Prince of Transylvania and ruler of a part of the Kingdom of Hungary, the village belonged to Thomas Mihályfy. The castle was ravaged in 1562 by the revolted Szeklers. After the fall of the Mihályfy family, the Chancellor of Transylvania, Farkas Kovacsóczi owned the estate, which later came down to the Tholdalagi family. The Tholdalagi family belongs to one of the great magnate families of Transylvania, with nicknames deriving from Ercea and Iclod, but originating from Toldal, Mureș County, Romania – their ancient demesne from the 16th century. Mihály I. Tholdalagi (1580–1673), one of the wisest diplomats in the Principality, reshaped the original building to an impressive castle in the 1630s, whose size and adjoining buildings are described in the Inventory dating from 1680. The first members of the Tholdalagi family came to Transylvania from Hungary. According to the family traditions, and also mentioned in their Certificate of Count, their ancestor is the extinguished Alaghi family member, András, who obtained Toldalag settlement together with its neighbouring Ercse in 1453; hence the nickname “Ercsei”. Thus, Mihály Tholdalagi’s parents were Balázs from Gáldtő and Borbála Bessenyei [1].

Exerting the Principle of Collective Guilt against the Transcarpathian Hungarians and Germans (Carrying into Effect the Decisions of the Military Council of the 4th Ukrainian Front in the Light of the NKVD1 Reports)
Authors: Dupka György 
Published: May 2018

Abstract
In his paper, Gyorgy Dupka deals with the tragic fate of the Transcarpathian Hungarians and Germans deported for ‘a three-day labour’ in the period of 1944-1946. During the past twenty years, he succeeded in collecting and, in some measure, publicizing sufficient archival materials to open up the facts of the anomies committed by the Soviet military authorities in the fall of 1944 and at the beginning of 1945. All these facts are supported by cogent data and concrete names of the perpetrators. In his paper, the author shows primarily how in the light of the reports conceived by the NKVD and other Soviet central military administrations Order 0036 of the Military Council of the 4th Ukrainian Front was carried into effect.

Neural Flows in Hopfield Network Approach
Authors: Ionescu Carmen , Panaitescu Emilian , Stoicescu Mihai 
Published: May 2018

Abstract
In most of the applications involving neural networks, the main problem consists in finding an optimal procedure to reduce the real neuron to simpler models which still express the biological complexity but allow highlighting the main characteristics of the system. We effectively investigate a simple reduction procedure which leads from complex models of Hodgkin-Huxley type to very convenient binary models of Hopfield type. The reduction will allow to describe the neuron interconnections in a quite large network and to obtain information concerning its symmetry and stability. Both cases, on homogeneous voltage across the membrane and inhomogeneous voltage along the axon will be tackled out. Few numerical simulations of the neural flow based on the cable-equation will be also presented.

Published: May 2018

Abstract
The information-theoretical entropy, also called the “classical” entropy, was introduced by Wehrl in terms of the Glauber coherent states (CSs) | z > , i.e. the CSs corresponding to the one-dimensional harmonic oscillator (HO-1D). In the present paper, we have focused our attention on the examination of the information-theoretical entropy, i.e. the Wehrl entropy, for both the pure and the mixed (thermal) states of some quantum oscillators.

Published: May 2018

Abstract
This paper investigates the possibility to improve the filtering process of flue gas by separation of suspended nanoparticle using dielectrophoresis. The study focuses on the particles having an average radius of about 50-150 nm, that cannot be filtrated by classical techniques but have a harmful effect for environment and human health. The size distribution nanoparticles collected from the flue gas filters of a hazardous waste incinerator plant were evaluated. Based on obtained experimental data and a proposed mathematical model, the concentration distribution of nanoparticle suspended in flue gas inside a microfluidic separation device was analyzed by numerical simulations, using the finite element method. The performances of the device were described in terms of three new specific quantities related to the separation process, namely Recovery, Purity and Separation Efficiency. The simulations could provide the optimal values of control parameters for separation process, and aim to be a useful tool in designing microfluidic devices for separating nanoparticle from combustion gases.

Pre-
performance routines followed by free throw shooting accuracy in secondary basketball players
Authors: Phelps Ashley , Kulinna Pamela 
Published: May 2018

Summary
Study aim: The purpose of the current study was to determine whether existing pre-performance routines had an effect on free throw shooting accuracy in high school pupils as compared to shooting without a pre-performance routine.

Materials and methods: Participants were 34 freshman high school basketball players. Twenty male (n = 20) and fourteen female (n = 14) of various ethnic backgrounds were randomly assigned to a condition and were asked to implement a pre-performance routine in one condition and a non-pre-performance routine in another condition for free throw shooting. A within subjects crossover design was used to analyse the data based on a pre-performance routine and a non-pre-performance routine framework. The pre-performance routine conditions were considered the experimental conditions. A Missed-Made Shots table was used to track performance (miss-made shots) for the shots in both conditions.

Results: There were differences between the experimental condition (pre-performance routine) and the comparison condition (non-pre-performance routine) Z(22) = –4.61, p < 0.01 with the experimental condition’s median scores out-performing the comparison condition scores; however the differences were very small.

Conclusions: These findings suggest that there were differences between the experimental condition (pre-performance routine) and the comparison condition (non-pre-performance routine). Results suggest that there may be additional relevant factors in addition to pre-performance routines that should be considered in helping youth develop closed motor skills (e.g., mental imagery, physical exertion, outside factors – audience).

Published: May 2018

Abstract
In the past few years the use of unmanned aerial vehicles in Lithuania has significantly increased. However, enjoying the advantages of this technology, which improves society’s socio-economical safety (public safety in a broad sense), raises some privacy concerns. This article analyses European Union and national legal regulations regarding the use of unmanned aerial vehicles as well as legal tools for defence of the right to privacy or prevention from its breaches in the Republic of Lithuania. Unmanned aerial vehicles have become popular only recently; thus, legislation regarding their use has not yet become a common topic among lawyers. Furthermore, case law of the Republic of Lithuania is silent about it. Thus, the authors model a situation of breach of privacy using an unmanned aerial vehicle and analyse possible defence mechanisms.
