AbstractThe morphological and biochemical modification of oviductal epithelial cells (OECs) belongs to the compound process responsible for proper oocytes transport and successful fertilization. However, the main mechanisms which regulated this process are still not entirely known. Moreover, the OECs metabolism, which may be identified as the “cellular activity” marker, is poorly recognized. In this study we investigated the fructose and mannose metabolic pathway in porcine OECs primary long-term cultured in vitro.In our study, we employ a primary long term in vitro culture (IVC) and microarray approach (the Affymetrix microarray were used for analysis of transcriptomic profile of OECs) for expression levels analysis.We found that from the whole analyzed transcriptome, 1537 genes were upregulated and 995 were down regulated after 7 days of culture, 1471 genes were upregulated and 1061 were downregulated after 15 days of culture and 1329 genes were upregulated and 1203 were downregulated after 30 days of culture. Moreover, the differential expression of SORD, FPGT, PFKFB4, TPI1, MPI, ALDOC, HK2 and PFKFB3 at 24 hours, 7 day, 15 day and 30 day, was also observed.We suggested that fructose and mannose metabolism may be important molecular bio-marker of porcine OECs capability in in vitro model. The metabolic profile is significantly accompanied by cells proliferation in vitro. The transcriptomic profile of SORD, FPGT, PFKFB4, TPI1, MPI, ALDOC, HK2 and PFKFB3 expression may be identified as “fingerprint” of fructose and mannose metabolism in OECs as well as involved in cellular in vitro developmental capacity in pigs.
Investigating the degree of humorous enjoyment in reading Chinese language errors
Authors: Chen Guangyan 
Published: October 2017

AbstractSecond language learners often make errors when they use their target language for communication. People perceive some of these errors as humorous. Many factors influence these perceptions. The purpose of this study is to investigate how these factors affect people’s perceptions when they read CSL (Chinese as a second language) learners’ humorous errors. The factors mainly refer to error stimuli and readers’ backgrounds. The researcher collected 25 error stimuli from two popular and often-cited online articles. 57 participants responded to these errors and rated them in the following three categories: Very Funny, Somewhat Funny, and Not Funny. These participants included 51 Native Speakers (NSs) of Chinese and six Non-Native Speakers (NNSs). The NSs consisted of 28 females and 23 males. Out of the participants, 17 were Chinese teachers and 40 were non-teachers. The results indicate that teachers perceived these texts as less funny than non-teachers; No significant gender difference was found; NNSs seemed to perceive these error stimuli as less funny than NSs, however, readers should be cautious in interpreting this result because of the limited number of NNSs. In addition, this study compared the humorous texts that were perceived as the funniest and the ones perceived as the least funny. The results demonstrate that an error-evoked “Very Funny” joke text had two overlapping and opposing scripts. The more overlapping and opposing the two scripts within a joke text were, the more humorous enjoyment a reader experienced. These findings improve our understanding of the interrelationship of language and humor that has been neglected in CSL, Chinese linguistics, and humor literature.

Published: October 2017

Abstract
A recently proposed approach for the production of syngas is Tri-reforming process. Significant preferences of tri-reforming over conventional reformers are high methane conversion in a single unit, in situ heat generation, carbon dioxide consumption and adjustable outlet H2/CO ratio. In this work, a one dimensional mathematical model was developed for a novel axial-flow spherical packed bed tri-reformer. The results of reforming model were compared with the process data obtained from conventional Lurgi-steam reformer (CSR). Effects of feed flow rate, inlet temperature and length per radius (L/R) of the reactor on outlet hydrogen yield, methane conversion and H2/CO ratio were also studied. To maximize the outlet hydrogen yield, operation conditions and L/R ratio of the reactor were optimized applying differential evolution (DE) method. Obtained results were then compared with non-optimized condition. High methane conversion (99.68 %), high hydrogen yield (1.896) and much lower pressure drop were the superiorities of the presented reactor to the previous configurations.

Authors: Pawęska Katarzyna , Bawiec Aleksandra , Pulikowski Krzysztof 
Published: October 2017

Abstract
Treatment of wastewater produced in Service Areas (SA) located on expressways and highways is a worldwide problem because of increasing amount of roads and specific composition of those kinds of sewage. Insufficient removal of pollutants from wastewater discharged into surface water may cause serious environmental problems. In the present study efficiency of treatment of wastewater with high ammonium concentration in biological membrane system used on SA was investigated. Concentrations of ammonia nitrogen in wastewater flowing into bioreactor in none of the tested objects did not fall below 99.0 mg of N-NH4·dm−3. Because of high ammonium content in sewage and high pH reaching value about 9, it is almost impossible to create favorable conditions for microorganisms that run purification processes resulting in low efficiency of phosphorus and nitrogen removal (reduction of biogenic compounds did not exceed 15%). Treatment of wastewater consisting mainly of urine with commonly used biological membrane technology has to be widely tested to perform suitable quality of discharged wastewater, to provide safety of surface water environment.
Electrochemical, optical and morphological properties of poly (N-vinylcarbazole/TiO2) and (N-vinylcarbazole/aniline)/TiO2 copolymer prepared by electrochemical polymerization
Authors: Bouriche Ouahiba , Bouzerafa Brahim , Kouadri Hicham 
Published: October 2017

AbstractPoly (N-vinylcarbazole) (PVK) and a new copolymer, PVK/polyaniline (PANI), have been successfully prepared by electrochemical polymerization of N-vinylcarbazole (NVK) and NVK/aniline from acetonitrile medium and LiClO4 supporting electrolyte. Composite thin films were studied by cyclic voltammetry (CV) in LiClO4/acetonitrile solutions on an indium tin oxide (ITO) electrode. The influences of concentration of titanium dioxide (TiO2) on the electrochemical properties of these composite materials were also investigated. The results of scanning electron microscopy (SEM) confirm the presence of TiO2 in the composite, which consequently modifies the morphology of the film significantly. Topographical analysis has shown that TiO2 nanoparticles (NPs) affect the morphology of thin films (roughness). The analysis of the voltammograms of PVK and of (PVK+PANI) before and after the addition of TiO2 at different concentrations shows a redox couple which was not observed in the absence of TiO2. The impedance spectroscopy study shows that the resistance of the PVK and (PVK+PANI) films decreases with increasing of TiO2 concentration, and this in turn contributes to a good conductivity of the film. The optical characterization of the composites has been carried out by UV-Vis absorption and photoluminescence (PL) spectroscopy and it was noted that the samples (PVK+10−2 TiO2) exhibited high transmittance (83%) in the visible region and a low gap value (2.69 eV) which confirms that this material can be used in a photovoltaic cell. This is explained by the introduction of the donor levels in the band gap of PVK by the TiO2, due to an effective doping.

Abstract
We construct special classes of totally geodesic almost regular foliations, namely, complex radial foliations in Hermitian manifolds and quaternionic radial foliations in quaternionic Kähler manifolds, and we give criteria for their harmonicity and minimality.
Then examples of these foliations on complex and quaternionic space forms, which are harmonic and minimal, are presented.
An Efficient High-Frequency Method to Compute EM Scattering of a Target on Rough Surface
Authors: Yang Wei , Qi Cong-hui 
Published: October 2017

Abstract
The physical optics and shooting and bouncing rays method are combined to rapidly compute the electromagnetic (EM) scattering from electrically large three- dimensional targets on a dielectric rough surface. To avoid modeling the rough surface of infinite extent, image theory is first used to account for the EM interactions between the target and the infinite planar surface. Next, the dielectric rough surface is accounted for by multiplying the Fresnel reflection coefficient with a roughness coefficient. In this way, only the target needs to be modeled. Thus, the proposed method can reduce significantly the computational costs and achieve a reasonable accuracy for the composite scattering problem, such as a ship-sea model.

Abstract
Foot and mouth disease (FMD) poses a major constraint to international trade in animals and animal products in sub-Saharan Africa. A retrospective and serological survey was conducted in two major Border States of Sokoto and Kebbi in north-western Nigeria. This study was aimed at determining the sero-prevalence of FMD virus (FMDV) antibodies in cattle at international animal control posts and to examine cattle population movement across the border area for a period of one year (January to December 2014) from the available records. Eight hundred and eighty (880) sera samples were collected and screened for the presence of antibodies to FMDV using the competitive enzyme linked immunosorbent assay (ELISA) technique. The data were subjected to chi-square and relative risk to check for independence and association. An overall seropositive rate was found to be 55.2 % (486/880). A 79.9 % (359/450) sero-positive rate was obtained from the Kamba border, while 29.5 % (127/430) was found at the Illela border. Kamba showed a statistically significant (P < 0.05) higher sero-prevalence when compared with cattle that are crossing the Illela border (Relative Risk 2.70; 95 % Confidence Interval 2.317—3.149). Retrospective data from the control posts revealed that an average number of 2019 and 2747 of cattle, respectively, crossed the Kamba and Illela international borders monthly. The highest influx of animals from the Niger Republic through the Illela international border was encountered between the month of March and April 2014. The magnitude of the presence of FMDV Non-structural protein (NSP) antibodies in the study areas is an indication of the infection and the presence of the virus in the study areas and the neighbouring countries.

Abstract
In this study, the effects of salt concentration (1, 3 and 6% w/v) and ultrasound pretreatment (50 W for 5, 10 and 15 minutes) on extraction parameters and extracted essential oil from peppermint by ohmic-assisted hydrodistillation (OAHD), a recently innovated extraction technique, have been studied. The results showed that salt concentration significantly affected the extraction parameters of OAHD, while ultrasound pretreatment had negligible effect. Sudden eruption of essential oil glands was observed in scanning electron micrographs of all OAHDs mint leaves. GC-MS analysis did not indicate any noticeable change in the compounds of all the extracted essential oils. The results of this study showed that increase of electrolyte concentration could speed up OAHD process without any adverse effect on essential oil quality, while ultrasound pretreatment neither reduced process time nor increased extraction yield of OAHD.

Published: October 2017

Abstract
The preparation of the enantiomerically pure (R,R)-lactide (>99%ee) on the gram scale by alcoholysis of rac-lactide in the presence of Amano lipase PS is described. The synthesis of enantiopure lactide by this method is advantageous over traditional preparation via thermal tin-catalysed cyclisation of corresponding oligolactic acids, since the reaction temperature are much lower. That results that no meso-lactide is formed. The alcoholysis of rac-lactide with n-BuOH was studied in the presence of various enzymes in different solvent systems. The kinetic study of the alcoholysis of rac-lactide in the presence of CALB was performed.
Application of an Autonomous/Unmanned Survey Vessel (ASV/USV) in Bathymetric Measurements

Published: October 2017

Abstract
The accuracy of bathymetric maps, especially in the coastal zone, is very important from the point of view of safety of navigation and transport. Due to the continuous change in shape of the seabed, these maps are fast becoming outdated for precise navigation. Therefore, it is necessary to perform periodical bathymetric measurements to keep them updated on a current basis. At present, none of the institutions in Poland (maritime offices, Hydrographic Office of the Polish Navy) which are responsible for implementation of this type of measurements has at their disposal a hydrographic vessel capable of carrying out measurements for shallow waters (at depths below 1 m). This results in emergence of large areas for which no measurement data have been obtained and, consequently, the maps in the coastal zones are rather unreliable.
The article presents the concept of bathymetric measurements for shallow waters with the use of an autonomous, unmanned survey vessel (ASV/USV). For this purpose, the authors modernized a typical ASV/USV unit with standard radio remote control system to the fully autonomous mode. As part of the modernization, the route planning software was created. The developed software works based on, alternatively, GNSS measurements of the coastline, or satellite images. The system was supplemented by an own autopilot (adapted for flying drones). Moreover, the method of controlling electric motors was changed thanks to the use of own electronic circuit.
The modernized ASV/USV measuring system was verified by performing bathymetric measurements of the retention reservoir in Gdansk, Poland. Then, the obtained measurement data were used to create a digital bottom model and a bathymetric map of the reservoir.
Problems of the Starting and Operating of Hydraulic Components and Systems in Low Ambient Temperature (Part IV)
Authors: Jasiński Ryszard 
Published: October 2017

AbstractDesigners of hydraulically driven machines and devices are obliged to ensure during design process their high service life with taking into account their operational conditions. Some of the machines may be started in low ambient temperature and even in thermal shock conditions (due to delivering hot working medium to cold components). In order to put such devices into operation appropriate investigations, including experimental ones - usually very expensive and time-consuming, are carried out. For this reason numerical calculations can be used to determine serviceability of a hydraulic component or system operating in thermal shock conditions. Application of numerical calculation methods is much less expensive in comparison to experimental ones. This paper presents a numerical calculation method which makes it possible to solve issues of heat exchange in elements of investigated hydraulic components by using finite elements method. For performing the simulations the following data are necessary: ambient temperature, oil temperature, heat transfer coefficient between oil and surfaces of elements, as well as areas of surfaces being in contact with oil. By means of computer simulation method values of clearance between cooperating elements as well as ranges of parameters of correct and incorrect operation of hydraulic components have been determined. In this paper results of computer simulation of some experimentally tested hydraulic components such as axial piston pump and proportional spool valve, are presented. The computer simulation results were compared with the experimental ones and high conformity was obtained.
Modern Modeling of Water Hammer
Authors: Urbanowicz Kamil 
Published: October 2017

Abstract
Hydraulic equipment on board ships is common. It assists in the work of: steering gear, pitch propellers, watertight doors, cargo hatch covers, cargo and mooring winches, deck cranes, stern ramps etc. The damage caused by transient flows (which include among others water hammer) are often impossible to repair at sea. Hence, it is very important to estimate the correct pressure runs and associated side effects during their design. The presented study compares the results of research on the impact of a simplified way of modeling the hydraulic resistance and simplified effective weighting functions build of two and three-terms on the estimated results of the pressure changes. As it turns out, simple effective two-terms weighting functions are able to accurately model the analyzed transients. The implementation of the presented method will soon allow current automatic protection of hydraulic systems of the adverse effects associated with frequent elevated and reduced pressures.

Published: October 2017

AbstractUrbanization is a global phenomenon and currently more than half of the world’s population lives in urban areas. Studies on geomorphological heritage and the development of specific methods of investigation (assessment, inventories, cartography) are, however, relatively rare and limited. This paper first describes the relationships between urbanization and geomorphology. Secondly, it presents an overview of the main works on the urban geomorphological heritage. Then, the main methods of investigation are presented. Finally, we discuss the challenging issues concerning the protection and the promotion of the urban geomorphological heritage.

Published: October 2017

Abstract
The city of Ljubljana lies at the intersection of various geomorphological regions that have strongly influenced its spatial organization. Prehistoric settlements were built on marshland, a Roman town was built on the first river terrace of the Ljubljanica River, and in the Middle Ages a town was built in a strategic position between the Ljubljanica River and Castle Hill. The modern city absorbed all usable space between the nearby hills. This paper reviews some relief features in Ljubljana, their influence on the city’s spatial development, and urban geoheritage. The results indicate new possibilities for urban geoheritage tourism in the Slovenian capital and its surroundings.
Potential Values of Urban Geotourism Development in a Small Polish Town (Pruszków, Central Mazovia, Poland)
Authors: Górska-Zabielska Maria , Zabielski Ryszard 
Published: October 2017

Abstract
The paper presents abiotic resources which are located in a small town in central Poland. They remain unknown to authorities and inhabitants. For the first time they are illustrated in a scientific paper. The objects of local geological heritage point to geodiversity of this district town in the south-western Mazovia. When the geodiversity is interpreted in a simple, an understandable way, it may become attractive for tourists. We show how abiotic resources located within an urban area can be used to support urban geotourism development. The scientific, educational and aesthetic values of these resources may create the town image in accordance with the principles of environmental protection.

Published: October 2017

Abstract
The geomorphological analysis of historically urbanized areas is the best scientific way to understand how the extant geomorphological factors conditioned urbanization. It also provides a baseline to enable comparisons to be made with the modern environment. This paper considers four urbanized historical sites on the Adriatic coast (Italy) that owe their urban development to particular geomorphological and environmental conditions that were modified over the centuries from the Roman age to the present day. The focus here is on the evolution of the shoreline and associated geomorphic variables (streambeds and river mouths migration). These factors are fundamental for determining the development of a city, both as basic boundary elements – therefore including defence and protection – and also for the development of harbours.
Typology of Household Strategies of Action in Four Countries of Southeastern Europe in a Period of Economic Crisis
Authors: Cvetičanin Predrag , Lavrič Miran 
Published: October 2017

Abstract
In this paper, we explore whether the myriad production and consumption household practices in four societies of Southeastern Europe (Bosnia-Herzegovina, Croatia, Serbia and Slovenia) can empirically be reduced to a relatively small number of coherent and socially meaningful combinations, which we have labelled household strategies of action. Approaching the same data from two different angles, namely, using Multiple Correspondence Analysis (MCA) and Two-Step Cluster Analysis (TCA), we have identified five general household strategies and eleven more detailed and specific sub-strategies. More importantly, by projecting these strategies and sub-strategies onto the social space, we have shown that these household practices are linked to the class position of households. On a more general level, it is indicated that the study of household strategies can be viewed as a way of rendering relatively static structural approaches, in this case the Bourdieusian approach to social space, more dynamic.
