The results investigations of a soil having similar properties as lunar regolith performed at the Department of Drilling and Geoengineering, Faculty of Drilling, Oil and Gas, AGH University of Science and Technology in Kraków are presented in this paper.
The research was carried out jointly with the Space Research Centre, Polish Academy of Sciences in Warsaw. The objective of the cooperation was to minimize the cost of tests of penetrator KRET, which will be used on the surface of the Moon.
The American lunar regolith (e.g. CHENOBI) was used as reference soil.
The most important properties were presented graphically in the form of figures and tables: grain size distribution, selected physical properties (bulk density, colour), selected mechanical parameters (shear strength, inner friction strength, cohesion).
As a result the first Polish lunar soil analog AGK-2010 was produced.
A Test for the Stability of Networks
Authors: Rowinska-Schwarzweller Agnieszka , Schwarzweller Christoph 
Published: August 2013

Summary
A complex polynomial is called a Hurwitz polynomial, if all its roots have a real part smaller than zero. This kind of polynomial plays an all-dominant role in stability checks of electrical (analog or digital) networks. In this article we prove that a polynomial p can be shown to be Hurwitz by checking whether the rational function e(p)/o(p) can be realized as a reactance of one port, that is as an electrical impedance or admittance consisting of inductors and capacitors. Here e(p) and o(p) denote the even and the odd part of p [25].
From continental platform towards rifting of the Tisza Unit in the Late Triassic to Early Cretaceous

Published: August 2013

Abstract
The Upper Triassic-Lower Cretaceous successions of the Transdanubian part of the Mecsek and Villány- Bihor Zones of the Tisza Unit have been studied from the lithological, lithostratigraphical, sedimentological, microfossil and microfacies points of view in order to correlate and interpret the significant differences between them and to draw a conclusion about their geological and paleogeographical history. After an overview of the paleogeographical reconstructions of the broader area, the succession of the Mecsek and Villány-Bihor Zones and the debated Máriakéménd-Bár Range are introduced. Until the end of the Middle Triassic the study area acted as an entity. The first fundamental difference between the two zones can be recognized in the Late Triassic when marine carbonates were replaced by thick fluvial siliciclastics in the Mecsek Zone, while it is represented only by small, local lenses with a few and thin dolostone intercalations in the Villány Zone. The Mecsek Zone is bordered southward by one of the large listric faults to the north of which very thick siliciclastics developed in the Early to Middle Jurassic, whereas it is highly lacunose in the larger western part of the Villány-Bihor Zone. The break at the base is subaerial, higher in the succession it is shallow submarine. The sediment is silty, occasionally sandy crinoidal limestone of late Early Jurassic or even Middle Jurassic in age. The Upper Jurassic in the Mecsek Zone is composed of deep-water cherty limestone while in the Villány Zone it became a thick, shallowing pelagic limestone with reworked patch reef fragments. It is clear evidence that the Mecsek Zone had a thinned continental crust thanks to the nearby rift zone while in the Villány Zone the crust remained thick. The actualized version of the Plašienka’s paleogeographical model (Plašienka 2000) is introduced
Large-volume gravity flow deposits in the Central Carpathian Paleogene Basin (Orava region, Slovakia): evidence for hyperpycnal river discharge in deep-sea fans
Authors: Starek Dušan , Soták Ján , Jablonský Jozef , Marschalko Róbert 
Published: August 2013

Abstract
The deep-water clastic systems of the Central Carpathian Paleogene Basin contain megabeds, which are developed in distinctive stratigraphic horizons and can be traced over long distances. These beds are characterized by great individual thickness (4-13 m), uniform lithology and internal structures. On the basis of their lithology, sedimentary structures and sequence development, the megabeds are characterized by 15 individual facies and interpreted from the viewpoint of flow hydrodynamics. The grain-size distribution and internal structures of the megabeds point to their deposition from uniform turbulent flows. The main controlling factor for generation of such large voluminous flows is inferred in the sea-level changes, when a relative rising of sea level during the Eocene/Oligocene boundary was responsible for long-lasting accumulation of the clastic supply at the basin margins. The large volume of detritus from river discharge and ravinement surfaces of flooded land was accumulated on the shore and in the conduit heads where the sediment was remobilized by other triggers. The flows generated by catastrophic floods during the early Rupelian sea-level lowstand are thought to be the most probably triggering mechanism. The large highly erosive hyperpycnal flows from flooding rivers could erode accumulated deposits in the conduit or on steeper basin-margin slopes and could cause progressive increase of the sand volume in the flow. Conduit flushing appears to be the most probable source of sediment for the very large voluminous flows that were responsible for deposition of the Orava megabeds

Published: August 2013

Abstract
The Štiavnica Stratovolcano in Central Slovakia is the largest volcano in the Neogene to Quaternary Carpathian volcanic arc. A large caldera, an extensive subvolcanic intrusive complex and a resurgent horst with late stage rhyolite volcanites are the most characteristic features. The results of new K-Ar and Rb-Sr isotope dating using more sophisticated methodical approaches have changed our view on the timing of volcanic and intrusive activity. K-Ar dating of groundmass fractions combined with Rb-Sr isochron dating in the cases of possible rejuvenation has provided highly reliable results. The lifespan of the stratovolcano is apparently shorter than assumed earlier. Evolution of the stratovolcano took place in five stages during the Early Badenian to beginning of Early Pannonian time: (1) construction of the extensive andesite stratovolcano during the interval 15.0-13.5 Ma; (2) denudation of the volcano concluded with the initial subsidence of a caldera and the contemporaneous emplacement of a subvolcanic intrusive complex of diorite, granodiorite, granodiorite porphyries and quartz-diorite porphyries during the interval 13.5-12.9 Ma; (3) subsidence of the caldera and its filling by differentiated andesites during the interval 13.1-12.7 Ma - volcanic activity overlapping with the emplacement of the youngest intrusions; (4) renewed explosive and effusive activity of less differentiated andesites during the interval 12.7-12.2 Ma; (5) uplift of the resurgent horst in the central part of the caldera accompanied by rhyolite volcanic/intrusive activity during the interval 12.2-11.4 Ma. Extensive epithermal mineralization was contemporaneous with the uplift of the resurgent horst and rhyolite volcanic activity and continued till 10.7 Ma
ARTEMISIA SANTONICUM SUBSP. PATENS IN SLOVAKIA: THE SAD STORY OF OBLIGATE HALOPHYTE ON THE NORTHERN EDGE OF ITS DISTRIBUTION RANGE
Authors: Dítě Daniel , Eliáš Pavol , Melečková Zuzana 
Published: August 2013

Abstract
Historical and current occurrence of obligate halophyte Artemisia santonicum subsp. patens was studied in Slovakia during 2001-2012. The species has been occurred in the Podunajska nižina Lowland and the Vychodoslovenska nižina Lowland; 35 localities were found in total. The data from the Zahorska nižina Lowland is erroneous. Recently the number of localities decreased markedly and the species was confirmed only in 17 sites. Most of them (16) is situated in the Podunajska nižina Lowland and a single one has been confirmed in the Vychodoslovenska nižina Lowland. Based on our data, Artemisia santonicum subsp. patens belongs to the endangered (EN A2ac+4c) plants of the Slovak flora according to IUCN categories and criteria, because 50 % of locations were destroyed and survival prognosis is unfavorable for the most recent populations.
Lipophilic chemical exposure as a cause of cardiovascular disease
Authors: Zeliger Harold I. 
Published: August 2013

Abstract
Environmental chemical exposure has been linked to numerous diseases in humans. These diseases include cancers; neurological and neurodegenerative diseases; metabolic disorders including type 2 diabetes, metabolic syndrome and obesity; reproductive and developmental disorders; and endocrine disorders. Many studies have associated the link between exposures to environmental chemicals and cardiovascular disease (CVD). These chemicals include persistent organic pollutants (POPs); the plastic exudates bisphenol A and phthalates; low molecular weight hydrocarbons (LMWHCs); and poly nuclear aromatic hydrocarbons (PAHs). Here it is reported that though the chemicals reported on differ widely in chemical properties and known points of attack in humans, a common link exists between them. All are lipophilic species that are found in serum. Environmentally induced CVD is related to total lipophilic chemical load in the blood. Lipophiles serve to promote the absorption of otherwise not absorbed toxic hydrophilic species that promote CVD.

Authors: Simeonova Rumyana , Danchev Nikolai 
Published: August 2013

Abstract
The aim of the present study was to evaluate local irritant effects to rabbit skin following a single application of test samples of non-sterile polyamide non-absorbable surgical sutures POLYMED ®. The polar and nonpolar extracts were prepared by using saline solution and olive oil, respectively, after sinking the materials tested (2.0 g) in 10 ml of the corresponding liquid. Incubation was carried out at the temperature of 37°C for 72 h. The saline solution and pure olive oil, which had no contact with the materials tested, were used as negative control samples and were incubated under the same conditions as above. Assessments of the extracts from each material were conducted on 2 albino rabbits of the New Zealand breed. On the back of each animal, 5 intracutaneous injections of the extract tested and 5 injections of the control solution, each of 0.2 ml, were carried out. The degree of irritation was scored at 4, 24, 48, 72 hours after injection and no skin changes were found. The intracutaneous irritation index (III) was calculated and yielded 0.0. Hence it was concluded that under the experimental conditions the extracts of the material tested, i.e. non-sterile polyamide non-absorbable surgical sutures POLYMED ®, were ‘non-irritant’ to the skin of rabbits when compared with the respective control groups. The experimental procedure was conducted according to ISO10993-10.

Influence of Water Temperature on Results of Current Meter Calibration and Measurement
Authors: Mattas Daniel , Ramešová Libuše 
Published: August 2013

Abstract
On the basis of the results of calibration of current meters at water of varying temperatures, a hypothesis that water temperature influences measured water velocities was formulated. The analysis of our long-term data showed that the water temperature does have an influence on measured water velocity. This influence can be taken into account for practical purposes as a contribution to the uncertainty of measurements. The influence depends on the type of current meter propeller. This paper presents results obtained for the Ott C-2 current meter with propellers of the types 1, 2, 3, 5 and 6. Our analysis showed that the uncertainty is equal or less than 5% for measurements carried out in water with temperatures above 8°C. The differences between measured water velocities for water temperatures 5°C and 20°C reached maximum 6% (depending on the propeller) in a slowly flowing water (rotational frequency n = 1 s-1). For rotational velocity n ≥ 2 s-1 the differences between velocities measured at water temperatures 5 and 20°C were mostly under 3%. The less influenced propeller is of type 3 for which the uncertainty of measurement does not reach 5% even for water temperature 1°C if the rotational frequency is bigger than 0.7 s-1.
Predicting Longitudinal Dispersion Coefficients in Sinuous Rivers by Genetic Algorithm
Authors: Sahay Rajeev Ranjan 
Published: August 2013

Abstract
In the present work, existing empirical expressions for longitudinal dispersion coefficient of rivers (K) are evaluated. They are found inadequate primarily because these expressions ignore the channel sinuosity, an important parameter representing a river’s transverse irregularities that affect mixing process. Hence, a new expression for K is derived taking into account the sinuosity besides few of other hydraulic and geometric characteristics of a river. The model makes use of genetic algorithm (GA) on published field data. Based on several performance indices, the new expression is found superior to many existing expressions for estimating K. The sensitivity and error analysis conducted on parameters of the new expression show the channel sinuosity an important input for predicting K accurately. Any error in measurement of sinuosity would lead to significant deviation in the longitudinal dispersion coefficient in sinuous rivers.

Published: August 2013

Abstract
Twelve predictive bedload sediment transport equations are rated against 14 sets of gravel-bed river field data collected by handheld bedload sampler in Narmab River, northeastern Iran. To evaluate these formulas two types of grain size namely bedload and bed material were used. The results show that the equations of Engelund and Hansen, Van Rijn and Einstein perform well with bed material grain size, while Shocklitsch, Meyer-Peter and Mueller, and Frijlink yield the best results using the bedload grain size.
Dual time point imaging fluorine-18 flourodeoxyglucose positron emission tomography for evaluation of large loco-regional recurrences of breast cancer treated with electrochemotherapy
Authors: Wichmann Matthiessen Louise , Hjorth Johannesen Helle , Skougaard Kristin , Gehl Julie , Westergren Hendel Helle 
Published: August 2013

Abstract
Background. Electrochemotherapy is a local anticancer treatment very efficient for treatment of small cutaneous metastases. The method is now being investigated for large cutaneous recurrences of breast cancer that are often confluent masses of malignant tumour with various degrees of inflammation. To this end 18-Flourine- Flourodeoxyglucose-Positron Emission Tomography/Computed Tomography (FDG-PET/CT) could be a method for response evaluation. However, a standard FDG-PET/CT scan cannot differentiate inflammatory tissue from malignant tissue. Dual point time imaging (DTPI) FDG-PET has the potential of doing so. The purpose of this study was to investigate if DTPI FDG-PET/CT could assess response to electrochemotherapy and to assess the optimal timing of imaging.
Patients and methods. Within a phase II clinical trial 11 patients with cutaneous recurrences had FDG-PET/CT scans at three time points: 60 min, 120 min and 180 min after FDG injection. The scans were performed before and 3 weeks after electrochemotherapy.
Results. A significant reduction in maximum standard uptake value at 60 min post injection was seen after treatment. Furthermore a change in the FDG uptake pattern was observed; from increasing uptake in up to 180 min post injection before treatment to stabilization of FDG uptake at 120 min post injection after treatment. The change in FDG uptake pattern over time lead to change of response in three target lesions; two lesions changed from stable metabolic disease to partial metabolic response and one lesion changed from partial metabolic response to stable metabolic disease. To ensure detection of the change in uptake pattern, scanning 60 and 180 min post injection seems optimal.
Conclusions. The present study shows that FDG-PET/CT 60 and 180 min after tracer injection is a promising tool for response evaluation of cutaneous recurrences of breast cancer treated with electrochemotherapy.
Evolution of the Rules Pertaining to the Issuing of ‘Official’ Interpretations of Tax Laws in Poland
Authors: Liszewski Grzegorz 
Published: August 2013

Abstract
Interpretations of the tax law (currently referred to as general and individual interpretations), issued by tax authorities, are a fairly new institution in Poland. They were introduced into the legal system by the Tax Ordinance Act of 29 October 1997. From that time these regulations were deeply changed three times. Now it seems that Polish legislator has finally succeeded in elaborating an appropriate model for binding interpretation of tax law that protects the interests of taxpayers. However, discussed regulations seem to need some other amendments. The objective of this article is to present the evolution of the provisions pertaining to the issuing of the so-called official interpretations of tax law and to point at certain shortcomings of the present regulations.

Published: August 2013

Abstract
Purpose: To establish the prevalence of fruit, vegetables and fast food consumption among students from Timisoara university center and provide evidence based information for increasing healthy food choices in order to prevent cardiovascular diseases. Material and Methods: We perform a cross-sectional study on 435 university students from the Timisoara university center, Romania (mean age: 22±4.8 years). The students were recruited using internet and public announcements in the student’s campus. All students completed a self administered diet questionnaire. Results: Two thirds of students are not eating fruits and vegetables daily. The prevalence of daily fruit consumption is even lower - 25%. Regarding fast food consumption we found that 26% of students are often consume these unhealthy products. Three main determinants was identified for choosing unhealthy diet: lack of time, school programme and lack of money. Conclusions: The unhealthy food consumption among students from Timisoara university center is highly prevalent. Increasing students’ nutrition-information knowledge and provision of nutrition education is recommended.

Abstract
The morphogenesis of the lake frog (Pelophylax ridibundus) vomeronasal organ was studied during different ontogenesis stages. The vomeronasal organ is laid after the formation of olfactory sacs, which are lined by olfactory epithelium, and after choan formation. Vomeronasal organ anlage takes place during G24 stage of larval development, which is the result of inflection and cell redistribution of olfactory epithelium rostroventral part. Formation of the vomeronasal organ finished at the beginning of metamorphosis. Apparently, vomeronasal organ appeared in aquatic Amphibia ancestors and after their transition from aquatic to terrestrial environment it developed new adaptive functions

L'impact du risque pays perçu sur le contrôle des filiales à l'étranger. Une étude qualitative sur le cas des multinationales françaises
Authors: Abdellatif Mahamat 
Published: August 2013

Cette recherche examine l’influence du risque politique et de la distance culturelle sur les outils et mécanismes de contrôle des filiales à l’étranger. Pour conduire cette étude, nous avons réalisé une série d’entretiens approfondis auprès de 12 multinationales françaises sur deux périodes : de juillet 2006 à janvier 2007, puis une seconde phase en juillet 2010. Nous montrons que le degré du risque pays perçu affecte davantage les mécanismes de contrôle à caractère informel que ceux présentant un caractère formel.
