Authors: Michalak Monika , Kiełtyka-Dadasiewicz Anna 
Published: March 2019

SummaryPlant-origin oils are an essential element of the diet, affecting the preservation of health, but also of significant importance for the care of skin and its appendages. Among fats of plant origin, oils from fruit seeds are an important group. They are a rich source of fatty acids, tocopherols, tocotrienols, carotenoids, flavonoids, phytosterols and other bioactive compounds that have positive effect in relation to specific functions of the human body. Fruit seed oils play an important role in health prophylaxis, because they prevent the development of diseases of civilisation, alleviate the effects of stress and slow down the ageing process of the body. Due to the beneficial effects on the skin, they are also used in cosmetology. In formulations of cosmetic preparations, plant oils are the basis for the administration of other active ingredients, but they are also used due to their biological properties. The article discusses in detail the composition, dietary and cosmetic importance of oil from the seeds of raspberries, blackcurrants, rose hips and grapes.

Published: March 2019

Abstract

Objective: This article illustrates how, on the subsidiary level, the mixture of management practices in Japanese manufacturing subsidiaries operating in Poland changes over time.

Methodology: Study represents the first, rigorous, longitudinal replication of Japanese Multinational Enterprise Study Group hybridization studies conducted using the original methodology. Researchers visited eight original research sites and measured changes after fourteen years in six of them.

Findings: The results indicate significant change in terms of manufacturing practices as well as in the localization of management. On the other hand, there has been practically no change in terms of equipment, organizational culture, and procurement methods.

Value Added: Article contributes to the existing literature in two ways. First it confirms dynamic nature of hybridization trough a longitudinal exploration of changes that took place in management practices. Secondly, it combines JMNESG methodology with the most recent developments in research methods, increasing its clarity and replicability thus paving a way for future longitudinal studies of hybridization.

Recommendations: Based on this research future studies could replicate JMNESG studies in various locations and contexts thus providing further insights into the nature of change in the hybrid factories operating around the world and the nature of Japanese management over the last 20 years.
The impact of using modern irrigation techniques on the ancient Mougheul palm grove, South-West of Algeria
Authors: Rezzoug Cherif 
Published: March 2019

Abstract
To resist against a hostile environment, the oases of Saoura developed ingenious techniques of catchment and sharing of water to exploit the rare and precious waters of the groundwater. But the intervention of modern irrigation techniques has disrupted the entire oasis system inside the oasis such as the spring, the palm grove and the ksar. These techniques have overexploited the groundwater supplying the palm grove in terms of quantity and quality.
For centuries, the oases of Mougheul used only the source (with a flow of 25 dm3∙s−1 in 2001) which is inside the oasis to irrigate the parcels and herds. After the year 2005, the state decided to supply the city of Bechar with drinking water through the catchment field of Mougheul through five modern boreholes, which had a profound impact on the oasis, its surroundings, and the whole artesian source.
In this work, we study the impact of the use of modern catchment systems on the water source and the life of the Mougheul population. By interviewing farmers and landowners about the impact of groundwater scarcity on the oasis. This allowed knowing the current state of the oasis and the reasons for its deterioration.

Authors: Kati Nida 
Published: March 2019

Abstract
In this study, CdZnO films prepared at different ratios of dopants (CdO:ZnO = 5:5, CdO:ZnO = 6:4, and CdO:ZnO = 8:2) were coated on glass surface by using the sol-gel spin coating technique. After this process, surface structure and optical properties of the CdZnO films was investigated by atomic force microscopy (AFM) and UV-Vis spectroscopy. The surface structure of the CdZnO films depended on the content of ZnO and CdO in the films. Low percentage of CdO films were very similar to the ZnO film but higher amount of CdO resuted in granular structures together with pure structure of ZnO in the films. Eg values of produced CdZnOs depended on the additions of CdO and ZnO. The obtained Eg values of the produced CdO:ZnO = 5:5 (S3), CdO:ZnO = 6:4 (S4), and CdO:ZnO = 8:2 (S5) films are 2.5 eV, 2.49 eV, and 2.4 eV, respectively.
Effect of Mn content in Fe(1−x)MnxB (x = 0, 0.25, 0.5, 0.75 and 1) on physical properties - ab initio calculations

Published: March 2019

Abstract
Structural, electronic, intrinsic magnetic, anisotropic elastic properties, sound velocities and Debye temperature of Fe1−xMnx B (x = 0, 0.25, 0.5, 0.75, 1) transition metal monoborides have been studied by first-principles calculations within the method of virtual crystal approximation (VCA) based on density-functional theory (DFT) through generalized gradient approximation (GGA). The average magnetic moment per cell increased with increasing of Mn content, which could be associated with the relationship between the composition and magnetic properties. The observed magnetic behavior of Fe1−xMnx B compounds can be explained by Stoner model. Lattice parameters and Debye temperature agree well with the experimental values. Furthermore, we have plotted three-dimensional (3D) surfaces and planar contours of the directional dependent Young and bulk moduli of the compounds on several crystallographic planes, to reveal their elastic anisotropy versus Mn content (x) in Fe1−xMnx B.

Published: March 2019

Abstract
Silicon as a raw material for solar cells can be produced by numerous methods. The carbothermic reduction of silica using electric arc furnace is the most widely used process in silicon industry. This paper presents a new approach to produce solar grade silicon using microwave furnace. Pellets of different sizes were prepared from a mixture of silica and carbon using water and polyvinyl alcohol as binder agents. Raman spectra indicated a peak at about 515 cm−1 attributed to silicon in the pellets prepared with polyvinyl alcohol, and peaks at about 523 cm−1 and 794 cm−1 attributed to silicon and silicon carbide, in the pellets prepared with water. The pellet size affects the absorption of microwave energy emitted from the magnetrons. Polyvinyl alcohol as a binder agent is promising for the production of silicon using microwave furnace.
Radionuclide neutron source trajectories in the closed nuclear fuel cycle
Authors: Stanisz Przemysław , Cetnar Jerzy , Oettingen Mikołaj 
Published: March 2019

Abstract
The highest efficiency in the usage of nuclear energy resources can be implemented in fast breeder reactors of generation IV. It is achieved thanks to the ability of consuming minor actinides (MAs) in energy production. One of the options to use this benefit is full recycling of MAs to close the nuclear fuel cycle. Monte Carlo burn up (MCB), an integrated burn-up calculation code, deals with the complexity of the burn-up process which is applied to the European Lead-cooled Fast Reactor (ELFR). MCB uses continuous energy representation of cross section and spatial effects of full core reactor model; however, it automatically calculates nuclide production in all possible reactions or decay channels. Multi-recycling of MAs can cause an intensified build-up of curium, berkelium and californium. Some of their isotopes are strong neutron emitters from spontaneous fission, which hinders fuel recycling. The implementation of a novel methodology for trajectory period folding allows us to trace the life cycle of crucial MAs from the beginning of the reactor life towards the state of adiabatic equilibrium. The result of the analysis performed is presented, showing the sources of strong contribution to the neutron production rate. The parametric sensitivity analysis method for selected nuclide reactions is applied, revealing sensitivity of transmutation chains for the production of neutron emitter isotopes.
Development and reproduction of Trichogramma cacoeciae Marchal, 1927 (Hymenoptera: Trichogrammatidae) on Cydia pomonella (Linnaeus, 1758) (Lepidoptera: Tortricidae) eggs
Authors: Mansour Mohammed 
Published: March 2019

Abstract
The effects of temperature treatments (15, 20, 25, 30, 35 ±1ºC), parasite age, host age, and availability of food on the development and reproduction of the egg parasite Trichogramma cacoeciae on Cydia pomonella eggs, were examined. The results showed that temperature had a profound effect on the mean number of parasitized eggs/females and the survival of immatures to the adult stage. Parasitization was highest on the 1st day after emergence, gradually decreasing for the next 2-10 days (depending on the temperature); it reached a peak at 25±1 ºC. The results also showed an inverse relationship between temperature, developmental time and mean adult longevity; the rate of development increased and longevity decreased with increasing temperature. The availability of food (honey) increased the parasitization rate, and the younger the host (C. pomonella eggs), the more susceptible it was to parasitization.

Size of home range of Tengmalm’s owl (Aegolius funereus) males during breeding season assessed by radio-telemetry in the Jizera Mountains, Czechia
Authors: Kouba Marek , Tomášek Václav 
Published: March 2019

Abstract
Animal home ranges are typically characterized by their size, shape and a given time interval and can be affected by many different biotic and abiotic factors. Understanding of animal movements and assessing the size of their home ranges are essential topics in ecology and necessary for effective species protection, especially concerning birds of prey. Using radio-telemetry (VHF; 2.1 g tail-mounted tags) we studied the movements of two Tengmalm’s owl (Aegolius funereus) males during the breeding season 2008 in a mountain area of Central Europe (the Czech Republic, the Jizera Mountains: 50˚ 50’ N, 15˚ 16’ E). We determined their average nocturnal hunting and diurnal roosting home range sizes. The mean hunting home range size calculated according to the 90% fixed kernel density estimator was 251.1 ± 43.2 ha (± SD). The mean roosting home range size calculated according to the 100% minimum convex polygon method was 57.9 ± 15.8 ha (± SD). The sizes of hunting home ranges during breeding in this study coincide with those previously reported by other studies focusing on Tengmalm’s owl males. However, we found the roosting home ranges were smaller in size compared to those previously reported. This result was most probably connected with different habitat structure in our study area, which was severally damaged by air-pollution in the past, thus probably offering fewer suitable hiding-places, for instance from predators. We found the roosting locations were concentrated in the oldest and densest Norway spruce forest patches. We emphasize that these parts of forest stands require the highest possible protection in our study area.
Influence of terrain attributes on organic carbon stocks distribution in soil toposequences of central Poland
Authors: Kozłowski Michał , Komisarek Jolanta 
Published: March 2019

Abstract
The paper presents the results of research on the relationship between topography of undulated morainic plateau of postglacial landscape and distribution of organic carbon stocks in soil toposequences. The mean value of the soil organic carbon stocks (SOCS) for Retisols/Luvisols (RT/LV) was statistically lower than for the Phaeozems/Gleysols (PH/GL) but for RT/LV a higher variation of SOCS in comparison to PH/GL was observed. On the basis of Pearson correlation coefficient, the cartographic depth to water (DTW), the topographic wetness index (TWI) and the saga wetness index (SWI) were the most strongly correlated with the SOCS from among 13 analysed topographic attributes. In addition, the DTW was more correlated with SOCS than other topographic variables. Moreover, the DTW based on the channel networks with 2 ha flow initiation thresholds better correlate with SOCS than DTW obtained on the basis of channel networks with 1 ha and 4 ha flow initiation thresholds. Using Stepwise multiple regression analysis (SMLR), we concluded that the topographic attributes controlling the soil water content and slope shape had most impact on SOCS of the undulated morainic plateau of agricultural ecosystem. In this landform, where the RT/LV and PH/GL soil sequences dominate, the SOCS can be estimated by the DTW, TWI and GC (general curvature) with an estimation error of 0.21 kg m−2. In view of the increasing availability of LiDAR data and power of GIS tools, the use of topographic metrics to assess spatial variability of soil properties will play an increasingly important role in the estimation of soil properties.
Impact of crop residues and biopreparations on nitrogen changes in Haplic Luvisol – model experiment
Authors: Šimanský Vladimír , Jonczak Jerzy , Kováčik Peter , Bajčan Daniel 
Published: March 2019

Abstract
Agroecosystem crop residues are considered to be a primary resource of organic substances, and are subject to the different transformation processes in the soil environment. The decomposition processes of organic substance can be also regulated by the application of the different biopreparations. The decomposition of organic substances in soil also causes changes in nitrogen content and its forms. It is essential for farmers to know about these processes in order flexibly to regulate and affect the transformation processes of the applied crop residues via the biopreparations directly in the production conditions. The changes of content and forms of nitrogen and its calculated parameters in Haplic Luvisol influenced by the applied crop residues (wheat – WR, rape – RR) and biopreparations (Betaliq, Trichomil) were monitored in the small-pot experiment carried out at the Department of Soil Science (FAFR, SUA-Nitra). The laboratory experiments were established for the incubation period 4, 7, 14, 28, 60, 90 and 180 days. The applied crop residues had statistically significant impact on the contents of total nitrogen (Nt) and potentially mineralizable nitrogen (Npot) and inorganic forms N, similarly also the values of labile nitrogen (LN) and nitrogen pool index (NPI). The biopreparations affected statistically significantly the average values Npot, LN, nitrogen lability index (NLI) and nitrogen management index (NMI). During the incubation period, the contents Npot and values LN and other calculated indexes of nitrogen fluctuated significantly.

Published: March 2019

Abstract
Compared to homogeneous traffic flow, traffic speed variation is drastic with the involvement of heterogeneity. With an intent of studying the negative upshot of fluctuating speeds of heterogeneous traffic on the environment, the current paper is the outcome of the research done on various highways located in the states of Andhra Pradesh and Telangana in India, with an objective of developing a comprehensive noise prediction model by taking into account the traffic and roadway factors. Quantified noise levels [Leq (dBA) and L10 (dBA)] revealed that for the traffic speed variation of 10 to 95 kmph, the traffic noise levels were significantly affected by the variations in the proportion of the vehicle. On a specific note, the proposed model can be effectively used for the highway traffic noise prediction especially for the heterogeneous traffic, as the difference between the measured and predicted noise levels are within 1 to 10 dB (A).
Measurement of Airport Efficiency. The Case of Colombia
Authors: Olariaga Oscar Díaz , Moreno Luis Pulido 
Published: March 2019

Abstract
Since the mid-1990s, Colombia’s main airports (including those with the highest traffic) have been privatized, transferring governance to private operators. The remaining airports in the network (the smallest ones) continue with public governance. Based on this, the objective of this research article is to know, analyse and even measure the airport efficiency in a context of structural reform and at the same time compare this with the measure in airports with public governance. The methodology used to carry out the study is the Data Envelopment Analysis, and this methodology uses only “technical variables” (that is, only those related to infrastructure). The main results of the research reveal higher efficiency indices in the major (or more important) airports, almost all of them under private governance, although there is also a group of them (usually very small airports) with very low efficiency levels.

İşletme sermayesi yönetimi ve karlılık ilişkisi literatürde geniş çapta araştırılmış olan bir konu olmasına rağmen, söz konusu ilişki çoğunlukla doğrusal modellerle test edilmiştir. Oysa ki işletme sermayesi unsurlarından alacaklar, stoklar, ticari borçlar ve karlılık arasındaki ilişki doğrusal olmayabilir. Özellikle düşük seviyelerdeki alacak, stok ve ticari borçların arttırılması karlılığı arttırırken, belirli bir düzeyin üzerindeki unsurların arttırılması karlılığa zarar verebilir. Bu çalışmanın amacı, 2005-2016 yılları arasında Borsa İstanbul Kimya, Petrol, Kauçuk ve Plastik Ürünler Sektöründe faaliyet gösteren işletmeler için işletme sermayesi yönetimi ve karlılık ilişkisini doğrusal olmayan modelle tespit etmektir. Uygulanan Genelleştirilmiş Momentler Yöntemi (GMM) yönteminin sonuçları özellikle alacaklar, ticari borçlar ve karlılık arasında doğrusal olmayan, konkav bir ilişkinin varlığına kanıt sunmaktadır. Stoklar için elde edilen sonuçlar ise teorik beklenti ile uyumlu değildir.
Numerical analysis of pressure fluctuation in a multiphase rotodynamic pump with air–water two-phase flow

Published: March 2019

Pressure fluctuation in single-phase pumps has been studied widely, while less attention has been paid to research on multiphase pumps that are commonly used in the petroleum chemical industry. Therefore, this study investigates the pressure fluctuation for a multiphase rotodynamic pump handling air–water two-phase flow. Simulations based on the Euler two-fluid model were carried out using ANSYS_CFX16.0 at different Inlet Gas Void Fractions (IGVFs) and various flow rate values. Under conditions of IGVF = 0% (pure water) and IGVF = 15%, the accuracy of the numerical method was tested by comparing the experimental data. The results showed that the rotor–stator interaction was still the main generation driver of pressure fluctuation in gas–liquid two-phase pumps. However, the fluctuation near the impeller outlet ascribe to the rotor–stator interaction was weakened by the complex gas–liquid flow. For the different IGVF, the variation trend of fluctuation was similar along the streamwise direction. That is, the fluctuation in the impeller increased before decreasing, while in the guide vane it decreased gradually. Also, the fluctuation in the guide vane was generally greater than for the impeller and the maximum amplitude appeared in the vicinity of guide vane inlet.
Infinite Dilution Activity Coefficients as Constraints for Force Field Parameterization and Method Development
Authors: Duarte Ramos Matos Guilherme , Calabró Gaetano , Mobley David 
Published: March 2019

Molecular simulations begin with an underlying energy model or force field, and from this, can predict diverse physical properties. However, force fields were often developed with relatively limited datasets, yet accuracy for diverse properties across a broad chemical space is desirable, so tests of such accuracy are particularly important. Here, to this end, we calculate 237 infinite dilution activity coefficients (IDACs), comparing with experimental values from NIST's ThermoML database. We found that calculated IDAC values correlate strongly with experiment (Pearson R of 0.92+/- 0.01), and allow us to identify specific functional groups which appear to present challenges to the force field employed. One potentially valuable aspect of IDACs, as compared to solvation free energies which have been frequently employed as force field tests, is that the same molecules serve both as solutes and solvents in different cases, allowing us to ensure force fields are not overly tuned to one particular environment or solvent.
