Abstract
With regard to gastric cancer, an important disease and a public health problem, it is expected that understanding the molecular make up of carcinomas will provide us with more precise targets for therapy. Indeed advanced molecular technology has made it possible to classify according to genotype instead of phenotype. For advanced stomach cancer, however, surgery is still the only option for cure. Yet, also after surgery, more than 50% of the patients will die of peritoneal dissemination of their disease. This review looks at the molecular mechanism of peritoneal spread of stomach cancer in order to arrive at a risk profile that enables medical personnel to raise the index of suspicion for peritoneal carcinomatosis. The peritoneal cancer index (PCI) provides a scoring system to measure the extent of peritoneal spread during laparoscopic staging. A recently developed device called the ‘MacSpec pen’ maybe of use to confirm the presence of tumor when there is doubt about the diagnosis. Treatment of peritoneal dissemination consists of cytoreduction, combined with hyperthermic peritoneal chemotherapy (HIPEC).
Which patient is going to benefit from surgical cytoreduction with intraperitoneal chemotherapy (for manifest peritoneal metastases)?

Abstract
The gastric cancer with peritoneal metastases still represents a serious problem in the oncological surgery, whereas the peritoneal metastases arising from colorectal cancer can be successfully treated using a multimodal therapy concept consisting of systemic chemotherapy, cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. The best survival rates in patients suffering from peritoneal metastases of gastric cancer have been reported by the ToGa trial, in patients with HER-2 positive expression who received standard chemotherapy and trastuzumab. Cytoreductive surgery and HIPEC are increasingly wining a place in the multimodal therapy of gastric cancer with peritoneal metastases, the criteria for such an aggressive therapy are strict and the operability needs to be previously assessed by laparoscopic exploration. Interesting new data are awaited from the German GASTRIPEC study and from the French GASTRICHIP study.
Orientations towards English among English-medium Instruction Students
Authors: Karakaş Ali 
Published: May 2018

Abstract
Based on the empirical data of my PhD research, this paper analyses the perceptions of 351 undergraduate students enrolled at English-medium universities towards English in terms of the language ideology framework. The students were purposively sampled from three programs at three Turkish universities. The data were drawn from student opinion surveys and semi-structured interviews. The findings paint a blurry picture, with a strong tendency among most students to view their English use as having the characteristics of dominant native varieties of English (American English & British English), and with a high percentage of students’ acceptance of the distinctiveness of their English without referring to any standard variety. The findings also show that many students’ orientations to English are formed by two dominant language ideologies: standard English ideology and native speaker English ideology. It was also found that a large number of students did not strictly stick to either of these ideologies, particularly in their orientation to spoken English, due, as argued in the main body, to their experiences on language use that have made them aware of the demographics of diverse English users and of the diverse ways of using English.
The ex vitro rooting of blueberry (Vaccinium corymbosum L.) microcuttings
Authors: Pacholczak Andrzej , Nowakowska Karolina 
Published: May 2018

Abstract
A growing demand for blueberry fruit has necessitated the development of an efficient propagation method of this species that would provide large quantities of planting material. The aim of this study was to evaluate the effects of auxin indole-3-butyric acid (IBA 50 mg dm−3), the commercial rooting powder Rhizopon containing 1% IBA, and salicylic acid (50 mg dm−3) on the in vivo rooting of microcuttings of Vaccinium corymbosum ‘Bluecrop’ and ‘Duke’. The contents of chlorophyll a + b, soluble proteins, free amino acids, as well as total soluble and reducing sugars were determined in rooted cuttings. All of the treatments increased the degree and percentage of rooting in the cuttings of both cultivars. While improving rhizogenesis in blueberry, salicylic acid did not perform as a cofactor of the auxin IBA. Foliar applications of IBA or salicylic acid (SA) increased the contents of soluble proteins, free amino acids and sugars, but no effects on chlorophyll levels were observed.
Exchange traded commodities as a category of innovative products on European financial markets
Authors: Marszk Adam 
Published: May 2018

Abstract
The article presents the main features of one category of innovative financial products – exchange traded commodities (ETCs) and results of the analysis of the European market for ETCs. ETCs are products listed and traded on the stock exchanges and they offer investors returns based on various assets (commodities or currencies). In contrast with the most widely recognized exchange traded funds (ETFs), ETCs are structured as debt instruments due to legal requirements regarding investment funds in the European Union. The European ETCs market is the largest in the world (in terms of assets its share in the global market in 2015 was close to 98%). It had developed rapidly until 2012 when total assets reached the record-high value of ca. 26,6 billion EUR (i.e. 9,5% of total assets of all exchange traded products listed in Europe). Over the next few years both the value of assets and market share of ETCs decreased significantly, mostly due to decline of the tracked assets’ prices (especially commodities) – during the analyzed time period the average flows to commodity or currency ETCs were close to 0. An important feature of the European market is its high concentration level, both in terms of companies launching ETCs and locations of the trade in the share of ETCs. Four ETC providers manage most of the assets (with the cumulated market share of over 94%). Three exchanges –in London, Milan and Frankfurt am Main account for almost the entire regulated market turnover of ETCs in Europe.
Non-Statistical Methods of Analysing of Bankruptcy Risk
Authors: Pisula Tomasz , Mentel Grzegorz , Brożyna Jacek 
Published: May 2018

Abstract
The article focuses on assessing the effectiveness of a non-statistical approach to bankruptcy modelling in enterprises operating in the logistics sector. In order to describe the issue more comprehensively, the aforementioned prediction of the possible negative results of business operations was carried out for companies functioning in the Polish region of Podkarpacie, and in Slovakia. The bankruptcy predictors selected for the assessment of companies operating in the logistics sector included 28 financial indicators characterizing these enterprises in terms of their financial standing and management effectiveness. The purpose of the study was to identify factors (models) describing the bankruptcy risk in enterprises in the context of their forecasting effectiveness in a one-year and two-year time horizon. In order to assess their practical applicability the models were carefully analysed and validated. The usefulness of the models was assessed in terms of their classification properties, and the capacity to accurately identify enterprises at risk of bankruptcy and healthy companies as well as proper calibration of the models to the data from training sample sets.
Preliminary studies on the molecular identification of sex in Taxus baccata L.
Authors: Zarek Marcin 
Published: May 2018

Abstract
The scientific objective of this research was to screen random amplified polymorphic DNA (RAPD) and intersimple sequence repeat (ISSR) primers in order to find the molecular markers enabling the distinction between male and female individuals of the European yew. This is an initial step toward understanding the mechanisms of sex determination in this species.
The study was conducted on European yew originating from two sites in Poland: the Zadni Gaj nature reserve near Cieszyn and the yew collection from the Botanical Garden of the Jagiellonian University in Krakow.
In the present study, 716 random primers (696 RAPD primers: OPA-OPAI_1-16 and 20 ISSR primers marked as UBC) were tested to identify the sex in European yew by means of a modified bulked segregant analysis (BSA) method. The work was conducted in three stages, gradually limiting the number of primers through the elimination of primers that either did not exhibit any differences between the examined groups or did not provide amplification products.
Among the tested primers, no ideal markers that would be present in all individuals of one sex but absent in the individuals of the other sex were found. However, some markers were found (A07_954, H13_729, J08_660, L12_390, U01_457, V14_527, AE03_941, AE03_1014) to occur with greater frequency in one sex. Using these, we further examined 13 band combinations (profiles) that were observed to occur only in male individuals and another 13 combinations that were observed only in female individuals, which could be used in the practical identification of sex.
This is the first report to ascertain the sex of Taxus baccata trees, and it may help to determine the sex at an early stage of development.
Gemstone deposits of Serbia

Published: May 2018

Abstract
Gemstone minerals in Serbia have never been regarded as an interesting and significant resource. Nevertheless, more than 150 deposits and occurrences have been recorded and some of them preliminarily explored in the last 50 years. The majority of deposits and occurrences are located within the Serbo-Macedonian metallogenic province and the most significant metallogenic units at the existing level of knowledge are the Fruska Gora ore district, Cer ore district, Sumadija metallogenic zone, Kopaonik metallogenic zone and Lece-Halkidiki metallogenic zone. The most important genetic type of deposits is hydrothermal, particularly in case of serpentinite/peridotite as host/parent rock. Placer deposits are also economically important. The dominant gemstones are silica minerals: chalcedony (Chrysoprase, carnelian, bluish chalcedony etc.), jasper (picture, landscape, red etc.), common opal (dendritic, green, milky white etc.), silica masses (undivided), and quartz (rock crystal, amethyst etc.). Beside silica minerals significant gemstones in Serbia include also beryl (aquamarine), garnet (almandine and pyrope), tourmaline, fluorite, rhodochrosite, carbonate-silica breccia, carbonate-silica onyx, silicified wood, howlite, serpentinite, marble onyx, and kyanite. This paper aims to present an overview of Serbian gemstone deposits and occurrences and their position based on a simplified gemstone metallogenic map of Serbia, as well as genetic-industrial classification of gemstone deposits and gemstone varieties.
Calcareous nannofossils of the Jurassic/Cretaceous boundary strata in the Puerto Escano section (southern Spain) — biostratigraphy and palaeoecology
Authors: Svobodová Andrea , Kośák Martin 
Published: May 2018

Abstract
We obtained material from the Puerto Escano section (southern Spain) to study the Jurassic/Cretaceous (J/K) boundary interval. The same samples had already been processed for magnetostratigraphic studies and biostratigraphic zonation based on calpionellids and ammonites (Pruner et al. 2010), but not for calcareous nannofossils. The aim of this study was to process the samples using micropalaeontological analysis and to compare and calibrate results for calcareous nannofossils with existing magnetostratigraphic and other biostratigraphic data. The calcareous nannofossil assemblage was dominated by the genera Watznaueria, Cyclagelosphaera, Nannoconus, Conusphaera and Polycostella. Several nannofossil bioevents were recorded on the basis of the distribution of stratigraphically important taxa, including zonal and subzonal markers. Based on the lowest occurrences (LO) of M. chiastius, N. globulus minor, N. wintereri, N steinmanii minor, N. steinmannii steinmannii, N. kamptneri minor and N. kampteri kamptneri, two nannofossil subzones (NJT 15b, NJT 17a) and two nannofossil zones (NJT 16, NK-1) were recognized. The paper introduces new palaeoecological data based on geochemical analysis and macrofauna occurrences.
Age and provenance of mica-schist pebbles from the Eocene conglomerates of the Tylicz and Krynica Zone (Magura Nappe, Outer Flysch Carpathians)
Authors: Oszczypko Nestor , Salata Dorota , Konečný Patrik 
Published: May 2018

Abstract
During the Łate Cretaceous to Palaeogene, the Magura Basin was supplied by clastic material from source areas situated on the northern and southern margins of the basin, which do not outcrop on the surface at present. The northern source area is traditionally connected with the Silesian Ridge, whereas the position of the southern one is still under discussion. A source area situated SE of the Magura Basin supplied the Eocene pebbly para-conglomerates containing partly exotic material. The studied clastic material contains fragments of crystalline rocks, and frequent clasts of Mesozoic to Palaeogene deep and shallow-water limestones. Numerous mica schists, scarce volcanites and granitoids as well as gneisses, quartzites and cataclasites were found in the group of crystalline exotic pebbles. Monazite ages of “exotic” mica-schist pebbles from the Tylicz, Zarzecze and Piwniczna-Mniszek sections document the Variscan 310±10 Ma age of metamorphic processes. The provenance of these exotic rocks could be connected with a remote source area located SE of the Magura Basin, which could be the NW part of the Dacia Mega Unit. The idea is strongly supported by palaeotransport directions from the SE, the absence of material derived from the Pieniny Klippen Belt, the presence of shallow water limestones, typical facies of the Median Dacides belt and metamorphic age distribution proved by monazite dating.
Hydrogeochemical Aspects Associated with the Mixing of Formation Waters Injected Into the Hydrocarbon Reservoir
Authors: Uliasz-Misiak Barbara , Chruszcz-Lipska Katarzyna 
Published: May 2018

Abstract
Formation waters extracted with crude oil and natural gas, due to their amount and chemical composition can be a problem for petroleum companies operating hydrocarbon deposits. On average, the world generates 2 to 3 times more water than oil. On average, the world generates 2 to 3 times more water than crude oil. T he amount of extracted water increases with the time of exploitation of the deposit, in the case of deposits at the final stage of depletion, the amount of extracted water is 5 to 8 times bigger than petroleum. Formation waters from hydrocarbons deposits are usually the highly mineralized brines. Large quantities of highly mineralized waters extracted with crude oil and gas are disposed of in various ways or neutralized. T he most common way of disposing of these waters is by injecting them into rock mass. As a result of injection of reservoir waters into hydrocarbon deposits, the waters interact with the storage formations. In these formations, there may be numerous reactions of mineral water with the rock environment. T he injection of reservoir waters will also cause mixing of waters that can disturb the state of thermodynamic equilibrium and will alter the chemistry of these waters. It was analyzed by the geochemical modeling of the interaction of the reservoir waters of Przemyśl natural gas field. Using the PHREEQC program, the chemical reactions related to the mixing of reservoir waters of different chemical types have been studied. It has been found that is possible to precipitation appropriated minerals as a result of mixing water with different chemical composition.

Abstract
Quite a big boom has recently been experienced in the technology of unmanned aerial vehicles (UAV). In conjunction with dense matching system, it gives one a powerful tool for the creation of digital terrain models and orthophotomaps. This system was used for the documentation of landslides and inaccessible parts of the Nástup Tušimice mine in the North Bohemian Brown Coal Basin (Czech Republic). The images were taken by the GATEWING X100 unmanned system that automatically executed photo flights an area of interest. For detailed documentation of selected parts of the mine, we used the method of digital terrestrial photogrammetry. The main objective was to find a suitable measurement technology for operational targeting of landslides and inaccessible parts of the mine, in order to prepare the basics for remediation work.

Published: May 2018

Abstract
A new class and a new order (Drabo corymbosae-Papaveretea dahliani and Saxifrago oppositifoliae-Papaveretalia dahliani) have been described, and the Papaverion dahliani validated. This is vegetation of zonal habitats in lowlands of the High Arctic subzone A (or Arctic herb, cushion forb or polar desert subzone) and of ecologically equivalent sites at high altitudes on the mountain plateaus of the High Arctic. The new class spans three continents – North America (Canadian Arctic Archipelago and Greenland), Europe (parts of Svalbard and Franz Josef Land), and Asia, including northern regions of Chelyuskin Peninsula (Taymir Peninsula), Severnaya Zemlya Archipelago and De Longa Islands.

Authors: Jasprica Nenad , Škvorc Željko , Milović Milenko 
Published: May 2018

Abstract
The results of a phytosociological investigation of the Quercus coccifera L. stands occurring along the Adriatic and Ionian coasts in south Albania are given. The surveyed stands are localized in the Thermo-Mediterranean and Meso-Mediterranean belts. On the basis of literature and unpublished data, Q. coccifera stands extend from the shoreline up to 680 m of altitude, within the Quercetea ilicis vegetation zone. According to numerical analysis, Q. coccifera stands in south Albania can be divided into two broad groups forming macchia of 3–4 m height and low shrublands [0.5–1.5(-2) m)] defined primarily by degree of human pressure and altitudes. In addition, relevés from Q. coccifera stands in Albania were differentiated from Croatian and Montenegrin the Fraxino orni-Quercetum cocciferae associations. Conversely, Q. coccifera stands in south Albania share several biological and ecological similarities with those of the eastern Adriatic coast: hemicryptophytes prevailed and the chorological spectrum highlights a clear dominance of the steno-Mediterraneans. With respect to indicator values, an important differentiation from the eastern Adriatic associations was shown only in higher light intensity of the stands in Albania.
Two new pioneer communities of Sorbus aucuparia and Sorbus aria in the southern Julian Alps
Authors: Dakskobler Igor 
Published: May 2018

Abstract
In the southern Julian Alps we described two communities whose tree layer is dominated by species from the genus Sorbus and noted two successional stages in the overgrowing of abandoned agricultural land (pastures, hay meadows). In the secondary succession on former subalpine pastures above the alp Planina Razor und under the Breginjski Stol ridge, where potential natural vegetation consists of subalpine beech forest, dwarf pine has been overgrown with mountain ash (Sorbus aucuparia) whose stands are classified into the new association Rhododendro hirsuti-Sorbetum aucupariae. Whitebeam (Sorbus aria) has established itself on steep former hay meadows in the belt of altimontane beech forests under Mts. Jalovnik and Krikov Vrh, on gullied slopes on mixed geological bedrock dominated by chert, and these stands are classified into the association Calamagrostio arundinaceae-Sorbetum ariae. While occupying only small areas these two pioneer stages, as the sites of some rare or protected species, are nevertheless important biotopes and play a vital role in protection against avalanches.

Published: May 2018

Abstract
The aim of the study was to assess changes in endurance performance in young runners (females and males) during two training seasons. It involved 19 male and 16 female athletes aged 15-17 specializing in track-and-field middle and long distances runs. The following parameters were measured three times during the training season: maximal oxygen uptake, running economy, and the level of the second ventilatory threshold. Training volume and intensity during each season were analyzed within an 8-week period prior to the exercise tests. The volume and intensity of training at various stages of preparation in both seasons were similar. During the first year of observation, significant improvements in relative volume of maximal oxygen uptake were reported both in female and male athletes. During the second training season, it was found that running economy improved both in women and men, with no changes in maximal oxygen uptake. The same (in terms of volume and intensity) endurance training carried out with young runners during two consecutive training seasons can result in different training effects.
Emotional Intelligence – Sales Performance Relationship: A Mediating Role of Adaptive Selling Behaviour
Authors: Wisker Zazli Lily , Poulis Athanasios 
Published: May 2018

Abstract
In this study, we examined the impact of emotional intelligence on sales performance. We posited that the impact of emotional intelligence (EI) on sales performance was mediated by adaptive selling behaviour (ASB). Data were collected from 281 sales people in the financial industries in Malaysia via the WLEIS emotional intelligence scale and ADAPTS adaptive selling behaviour scale, and were quantitatively analysed using structural equation modelling (SEM). Results were in keeping with the model. Three domains of EI were not found to impact sales performance directly but through ASB. Theoretical implications and managerial ramifications were also discussed.
CSR and Financial Performance: The Case of Polish Small and Medium Manufacturers
Authors: Zaborek Piotr 
Published: May 2018

Abstract
The paper explores the hypothesized link between involvement in social responsibility and financial performance. In particular, it looks at this relationship among Polish small and medium manufacturing companies that operate in food, beverage and cosmetics industries. The statistical analysis involves developing and testing structural model on the basis of data from a survey of 187 managers supplemented by validated financial metrics from an external database. The outcomes suggests the existence of a weak but statistically significant positive correlation between the CSR involvement construct and sales profit margin (β=0.2). However, CSR seems to have no discernible direct effect on ROA. The study, as the first project of this kind in Poland, adds to the sparse body of literature on financial outcomes of CSR in small and medium enterprises from emerging economies. Another distinguishing feature of this research is its methodological approach which compares favorably to many previous studies in terms of robustness.
