The correlation of foreign language proficiency, employment and regional competitiveness in the North Great Plain Region of Hungary
Authors: Hajdú Zita
Published: September 2019

Employment is one of the basic factors when evaluating a region’s competitiveness. Boosting employment figures will also increase individual income. However, the creation of jobs alone will not solve the problems of unemployment, as labour force with skills matched to labour market demands should also be available. Continuous development of the labour force, adjusted to recent needs in the labour market, can contribute to a region’s competitiveness. Mismatches between education and labour market requirements would be too expensive, especially for backward regions like the North Great Plain Region of Hungary. Foreign language education should also be adapted to the changing economy when selecting target languages and language skills. A workforce equipped with contemporary and needed second language skills can be an element in making a region attractive for investors. Although current trends show signs of improvement, Hungary and especially the North Great Plain Region still does not have much to offer in this respect. The paper examines the reasons for the low level of second language acquisition among Hungarians and the population of the North Great Plain Region and explores the ways foreign language knowledge could promote economic development.

Authors: Mézes Lili , Bíró Tibor , Tamás János , Petis Mihály
Published: September 2019

The aim of this research was the elaboration of the technological parameters of biological digestion and biogas production from poultry feather produced in large quantities by slaughterhouses. Feather protein was digested by Bacillus licheniformis, keratin desintegrator bacteria. Investigations focused on the optimalization of parameters influencing poultry feather biodegradation. The optimal range of pH, temperature, feather size and bacillus:feather ratio were determined in the experiments as well as the analysis of relationship between the examined parameters. In order to be able to track the dinamics of the biodegradation, we determined the extintion level of the liquid phase of the biodegraded material in the different experimental treatments. The results showed that the rate of hydrolisis was significantly higher in the treatments with bacteria than in the treatments without it. The most extensive digestion were observed in case of 1:3 feather:water ratio. The highest intensity of feather digestion were detected in the treatment with 1% microbe ratio.

Authors: Nagy Attila , Tamás János
Published: September 2019

Characterization of heavy metal polluted abandoned mining sites is complicated, as the spatial distribution of pollutants often changes dramatically.In our study, a hyperspectral data analysis of the Gyöngyösoroszi abandoned Pb-Zn mine, located in northern Hungary, where Záray (1991) reported serious heavy metal contamination, was carried out using ENVI 4.3. In this area, galena (PbS), goethite (FeO(OH)), jarosite (KFe3(SO4)2(OH)6), sphalerite ((Zn, Fe)S) and pyrite (FeS2) were the predominant minerals in the alteration zones was chosen as the target mineral.Spectral angle mapper (SAM) and BandMax classification techniques were applied to obtain rule mineral images. Each pixel in these rule images represents the similarity between the corresponding pixels in the hyperspectral image to a reference spectrum.As a result of hyperspectral imagery the distribution of pyritic minerals (sphalerite, galena) in the area was defined. Both of the mineral formations occur, especially in mine tailings, the area of the ore preparatory, and the Szárazvölgyi flotation sludge reservoir. According to the results, jarosite and goethite have similar distributions to sphalerite and galena. The results showed that hyperspectral remote sensing is an effective tool for thecharacterization of Pb, Zn and Fe containing minerals at the examined polluted sites and for modelling the distribution of heavy metals and minerals in extensive areas.This classification method is a basis of further detailed investigations, based on field measurements, to map the heavy metal distribution of the studied area and to quantify the environmental risks caused by erosion, which include DEM (digital elevation model) and climatic and hydrological data sources. Furthermore, it can be used primarily to support the potentially applicable phytostabilization technique and to isolate hot spots where only ex-situ remediation techniques can be applied.

Published: September 2019

Larger cultivated plots are heterogeneous from a pedological aspect. Heterogeneity causes problems during fertilization and harvest. The heterogeneity of cultivated areas can be compensated by fertilization which is based on soil analysis. We carried out research into the changes of the soil on three soil types, from 1966 to 2006, on the cultivated areas of Hajdúszoboszló.There were no significant changes in pH on chernozem meadow soil and meadow chernozem soil, but the pH increased in 0-30 cm layer on type meadow solonetz soil. The saline content decreased in every examined soil type. Decrease was the largest on meadow solonetz soil. Decline of humus content was the largest (0.95%) on chernozem meadow soil, and the smallest (0.39%) on meadow chernozem soil. The nitrogen content decreased with 528 ppm in the 0-30 cm layer on chernozem meadow soil, and decreased by 186 ppm on meadow solonetz soil. Phosphorus andpotassium content increased in every examined soil types. Rise of phosphorus content was 188.9 ppm in the 0-30 cm layer on meadow chernozem soil. The potassium content rose by 153.7 ppm on this soil type. Phosphorus content increased with 70.8 ppm, and potassium content increased by 57.6 ppm from 1966 to 2006.

Preacceleration of the multicharged ions with the different A/Z ratios in single RFQ channel
Authors: Altsybeyev Vladislav , Svistunov Yuri , Durkin Alexander , Ovsyannikov Dmitri
Published: September 2019

The preacceleration of multicharged ions with the different A/Z ratios extracted from electron cyclotron resonance (ECR) sources is discussed in this report. The capture ratio, emittances and current values of multicharged ions may be better if the ions are preaccelerated before their injection into a booster synchrotron.
There is a considerable possibility of separate preacceleration of multicharged ions with different A/Z ratios in a single radio-frequency quadrupole (RFQ) channel. The magnitude of the injection energy into RFQ is about a few keV/u whereas the magnitudes of the injection energy into booster or following linac cascade are 300 keV/u. In addition in this paper we discuss the approach of the fast channel parameter optimization technique by using swarm computations and gradient descend for improving the capture ratio. The optimizations aimed at changing the regular part of the RFQ or matching section profile to improve the matching of the arbitrary oriented in phase space input beam.
Parametric identification of reaction wheel pendulums with adaptive control
Authors: Alyshev Aleksandr , Dudarenko Natalia , Melnikov Vitaly
Published: September 2019

The paper proposes a new adaptive method for identification of the axial moment of inertia for a two degrees of freedom reaction wheel pendulum with viscous friction in suspension bearings. The pendulum contains a rod, a controlled DC motor and a flywheel attached to the rotor shaft. One end of the rod rotates in hinge bearing. The controlled DC motor with a flywheel is attached to the other end of the rod. The angles of rotation of the rod and of the controlled flywheel are measured by encoders. The proposed adaptive method is based on an energy algorithm with reversible symmetric motions of the pendulum system. The symmetric motions are used to eliminate the influence of dissipative factors on the results of identification. The results of computer modelling and experimental results show high accuracy of the proposed identification method.
Control over performance of qubit-based sensors
Authors: Borisenok Sergey
Published: September 2019

The extreme sensitivity of quantum systems towards the external perturbations and in the same time their ability to be strongly coupled to the measured target field makes them to be stable under the environmental noise. A high quality quantum sensor can be engineered even on the platform of a single trapped qubit.
There is a variety of optimal and sub-optimal algorithms for effective control over the quantum system states. Here we discuss the opportunity to improve the efficiency of the external field quantum sensor based on a single qubit via its feedback tracking.

The article presents the results of rate hygienic assessment for sambo-practicing athletes, and shows the
expediency of amateur combative sport involving students of higher educational institutions as an
alternative or an elective course to traditional approaches is showny. During the research, 2 experienced
groups were formed from among the students of Barnaul at the age of 19-21 years, engaged in sambo on
an amateur level for 2-3 years, engaged mainly in anaerobic load, aimed at increasing muscle mass and
as a control group, students, not engaged in any kind of sport, while related to the main group of health.
As a result, it was found that physical performance and physical fitness indicators in most cases are
statistically significantly higher in the experimental groups, compared to students who do not engage in
any kind of sport, while belonging to the main group of health in relation to physical training,
somatometric and somatoscopic the indices determined in the two control and experimental groups
showed that students of sambo-wrestlers do not have pathology of the arch of the foot. Physiometric
parameters reflecting the functioning of the cardiovascular and respiratory systems of the organism
showed great training of the systems in the representatives of the first control group, which was reflected
in the optimal values of arterial pressure and statistically significantly greater vital capacity of the
lungs, which is due to prolonged aerobic and intermittent physical exertion. Thus, it seems promising to
introduce the training process of fighting sambo in the physical activity of student youth.

Because of the system variations of tiny functional size, enhanced adjustment functions in bits are becoming more and more vital, as technology nodes proceed to scale, primary memory encounter increased energy with output and time impacts such as crosstalk, challenges in consumption and reliability. We suggest a sustainable strategy to error correction in deeply-scale memories in order to tackle increasing failure rates owing to issues. SRAM is frequently used for high-speed memory apps like cache. The SRAM memory layout (SRAM) main parameter is power consumption. SRAM cells are power starving and bad in traditional models. The low-power cell designs for power consumption, delay write and the power retard product has been analyzed in this paper. The most recent upgrade VLSI, primarily in the volatile memory form of the SRAM set built into the PMOS & NMOS series and which is to be included in the cache segment on the CPU and in microcontrollers that are electronically energy-related, and now we have improved the SRAM Array challenges.

It literally turns the wheels of industry and there is hardly any walk of life where rubber is not used. Rubber is an elastomeric which has a natural source as well as a synthetic analogue, known as synthetic rubber. Natural rubber accounts for 78% of the consumption in India where as the global consumption of rubber are 64% synthetic and 36% natural rubber. The social and economic benefits of rubber plantation produce are new jobs, renewable raw-materials, and absorbing carbon emissions. Rubber plantation creates a host of jobs, from directly rubber harvesting activities to those created indirectly to support the needs of the plantation workers. The agro-climatic conditions of NER are quite similar to that of South-West coastal region- the traditional rubber plantation area in terms of rainfall, humidity, temperature and suitable soil structure. It is for this reason the NER registered itself in the list of non-traditional region of rubber growers. In Dimoria region there are about thirty numbers of Rubber Plantation gardens. Villagers in this hilly area on the city outskirts have found way to stretch their income-growing rubber. The paper presents a case study of the rubber plantation of this locality.

Purpose- The purpose of this study is to explore the impact of a bank’s internal and external factors on net core operating margin in Indonesia’s Islamic commercial bank's companies.

Methods- A quantitative approach by using panel data regression with a period from 2nd quarter 2010 to 2nd quarter 2015. The object of this study is eight Islamic commercial banks companies which were listed in sharia bank directory of Central Bank of Indonesia and Financial Services Authority of the Republic of Indonesia, those selected by purposive sampling technique with specific criteria.

Findings- This study can be concluded that capital adequacy ratio and average operational cost have a positive and significant impact on the net core operational margin. On the contrary, financing to deposit ratio, bank size, operational efficiency ratio, and BI rate have a negative and significant impact on net core operational margin.

Research implications- The management needs to create an efficient banking system by reducing operational costs and improving management quality. Banks are also advised to increase the prudential principle in managing finance so that the risk of default can be minimized.
An overview of the cycloaddition chemistry of fulvenes and emerging applications
Authors: Swan Ellen , Platts Kirsten , Blencowe Anton
Published: September 2019

The unusual electronic properties and unique reactivity of fulvenes have interested researchers for over a century. The propensity to form dipolar structures at relatively low temperatures and to participate as various components in cycloaddition reactions, often highly selectively, makes them ideal for the synthesis of complex polycyclic carbon scaffolds. As a result, fulvene cycloaddition chemistry has been employed extensively for the synthesis of natural products. More recently, fulvene cycloaddition chemistry has also found application to other areas including materials chemistry and dynamic combinatorial chemistry. This highlight article discusses the unusual properties of fulvenes and their varied cycloaddition chemistry, focussing on applications in organic and natural synthesis, dynamic combinatorial chemistry and materials chemistry, including dynamers, hydrogels and charge transfer complexes. Tables providing comprehensive directories of fulvene cycloaddition chemistry are provided, including fulvene intramolecular and intermolecular cycloadditions complete with reactant partners and their resulting cyclic adducts, which provide a useful reference source for synthetic chemists working with fulvenes and complex polycyclic scaffolds.

The presence of mean-motion resonances (MMRs) complicates analysis and fitting of planetary systems that are observed through the radial velocity (RV) technique. MMR can allow planets to remain stable in regions of phase space where strong planet–planet interactions would otherwise destabilize the system. These stable orbits can occupy small phase space volumes, allowing MMRs to strongly constrain system parameters, but making searches for stable orbital parameters challenging. Furthermore, libration of the resonant angle and dynamical interaction between the planets introduces another long-period variation into the observed RV signal, complicating analysis of the periods of the planets in the system. We discuss this phenomenon using the example of HD 200964. By searching through parameter space and numerically integrating each proposed set of planetary parameters to test for long-term stability, we find stable solutions in the 7:5 and 3:2 MMRs in addition to the originally identified 4:3 MMR. The 7:5 configuration provides the best match to the data, while the 3:2 configuration provides the most easily understood formation scenario. In reanalysis of the originally published shorter-baseline data, we find fits in both the 4:3 and 3:2 resonances, but not in the 7:5. Because the time baseline of the data is shorter than the resonant libration period, the current best fit to the data may not reflect the actual resonant configuration. In the absence of a full sample of the longer libration period, we find that it is of paramount importance to incorporate long-term stability when the orbital configuration of the system is fit.
Dynamical Gaseous Rings in Global Simulations of Protoplanetary Disk Formation

Published: September 2019

Global numerical simulations of protoplanetary disk formation and evolution were conducted in the thin-disk limit, where the model included a magnetically layered disk structure, a self-consistent treatment for the infall from cloud core, and the smallest possible inner computational boundary. We compared the evolution of a layered disk with a fully magnetically active disk. We also studied how the evolution depends on the parameters of the layered disk model—the MRI triggering temperature and active layer thickness—as well as the mass of the prestellar cloud core. With the canonical values of parameters a dead zone formed within the inner ≈15 au region of the magnetically layered disk. The dead zone was not a uniform structure, and long-lived, axisymmetric, gaseous rings ubiquitously formed within this region owing to the action of viscous torques. The rings showed a remarkable contrast in the disk environment as compared to a fully magnetically active disk and were characterized by high surface density and low effective viscosity. Multiple gaseous rings could form simultaneously in the dead zone region, which were highly dynamical and showed complex, time-dependent behavior such as inward migration, vortices, gravitational instability, and large-scale spiral waves. An increase in MRI triggering temperature had only marginal effects, while changes in active layer thickness and the initial cloud core mass had significant effects on the structure and evolution of the inner disk. Dust with large fragmentation barrier could be trapped in the rings, which may play a key role in planet formation.
