Abstract
Focus assessed echocardiography (FATE) provides an excellent possibility to evaluate basic haemodynamic determinants, such as preload, afterload, contractility, compliance and relaxation, by observing obvious pathology, assessing wall thickness and chamber dimensions, biventricular function, and pleura, and relating the acquired information to the clinical situation. The goal of this study was to evaluate the applicability of FATE protocol in cardiac ICU when it was performed by inexperienced examiner. A total of 101 patients with acute myocardial infarction (AMI) were enrolled in the study. All AMI subjects were examined by two examiners with no previous experience in ultrasound using standard FATE protocol with addition of inferior vena cava (IVC) and aortic views. Data collected by inexperienced examiners was compared with the data from echocardiography performed by a cardiologist. We acquired a mean number of 5.75 ± 1.2 informative echo windows for each patient of 7 used in protocol. Mean number of informative echo windows acquired for one patient was greater in the non-smoker compared to no respiratory disease patient group (6.0 ± 1.2 vs 5.3 ± 1.8; p = 0.032). Quantitative echo measurements from inexperienced examiners correlated with measurements conducted by a cardiologist: LVEDD (R = 0.74; p < 0.01); IVSd (R = 0.71; p < 0.01); LVPWd (R = 0.61; p < 0.01). Substantial inter-observer agreement was observed for evaluation of diastolic function (K = 0.68; p < 0.01) and presence of pleural effusion (K = 0.76; p < 0.01).
Structure of the EU28 plus ukraine economic region from the growth pole theory perspective

Published: January 2015

Abstract
Economic and debt crisis in Europe has brought along the question which member states could become a source of future economic growth of EU28 region. With respect to this question, this paper aims to contribute to this debate by identifying possible economic growth poles within the EU28 economic region. In light of recent debate centered on the future of the Ukraine we use a broad definition of the European economic space with EU28 as well as the Ukraine included. Our results show that the dominance of the United Kingdom has been successfully challenged by Germany and Poland represents the only country from the “new” EU countries that can be labeled as a European growth pole. Additionally, the heterogeneous distribution of growth pole potential partially resembles the distribution based on Zipf’s law but with a growth potential concentrated more in the upper part than in the case of Zipf’s law benchmark.
The empirical evidence for corporate tax competition among the EU member states
Authors: Huňady Ján , Orviská Marta 
Published: January 2015

Abstract
The paper is focused on the problem of corporate tax competition in EU as one of the current key issues for EU member states tax policies. The main objective is to empirically verify theoretical assumptions about corporate tax competition among EU member states. Based on the available empirical data we analyzed trends in effective and statutory tax rates and tested the theoretical assumption of possible spontaneous tax coordination. We found almost no support for spontaneous tax coordination for EU as a whole, but it appears to be more evident among neighbouring member states as well as in within the same regions. The differences in corporate tax rates between neighbour countries are mostly smaller and tend to shrink over the time. We have used panel data cointegration analysis to test for, and DOLS and FMOLS panel estimators to estimate, the long-run parameters. Finally panel vector error correction models (VECM) were used to examine short-run as well as long-run dependencies among the corporate tax policies of neighbouring EU countries. Based on our results we find evidence for relatively strong relationships between neighbouring EU member states in corporate tax rate setting.

Published: January 2015

Abstract
Trigeneration or Combined Cooling, Heat and Power (CCHP) which is based upon combined heat and power (CHP) systems coupled to an absorption chiller can be recognized as one of the best technologies recovering biomass effectively to heat, cooling and power. Co-gasification of the lignite and biomass can provide the possibility for safe and effective disposal of different waste types as well as for sustainable and environmentally-friendly production of energy. In this article, a trigeneration system based on an IC engine and gasifier reactor has been simulated and realized using Thermoflex simulation software. Performance results suggest that utilization of sustainably-grown biomass in a Tri-Generation Power Plant (TGPP) can be a possibility for providing cooling, heat and power demands with local renewable sources and reducing the environmental impacts of the energy conversion systems.

Published: January 2015

Abstract
The CO2 emissions from a building’s power system will change over the life time of the building, and this need to be taken into account to verify whether a building is Zero Emission (ZEB) or not.
This paper describes how conversion factors between electricity demand and emissions can be calculated for the European power system in a long term perspective through the application of a large scale electricity market model (EMPS). Examples of two types of factors are given: a conversion factor for average emissions per kWh for the whole European power system as well as a marginal factor for a specific region.

Authors: Asset Khabdullin , Zauresh Khabdullina 
Published: January 2015

Abstract
The study is focused on analysis of climate considerations of electricity supply systems in a pellet industry. The developed analysis model consists of two modules: statistical data of active power losses evaluation module and climate aspects evaluation module.
The statistical data module is presented as a universal mathematical model of electrical systems and components of industrial load. It forms a basis for detailed accounting of power loss from the voltage levels. On the basis of the universal model, a set of programs is designed to perform the calculation and experimental research. It helps to obtain the statistical characteristics of the power losses and loads of the electricity supply systems and to define the nature of changes in these characteristics. Within the module, several methods and algorithms for calculating parameters of equivalent circuits of low- and high-voltage ADC and SD with a massive smooth rotor with laminated poles are developed.
The climate aspects module includes an analysis of the experimental data of power supply system in pellet production. It allows identification of GHG emission reduction parameters: operation hours, type of electrical motors, values of load factor and deviation of standard value of voltage.

AbstractAs a work of propaganda, graphics Austroseraphicum Coelum Paulus Pontius should create a new reality, make appearances. The main impression while seeing the graphics is the admiration for the power of Habsburgs, which interacts with the power of the Mother of God. She, in turn, refers the viewer to God, as well as Franciscans placed on the graphic, they become a symbol of the Church. This is a starting point for further interpretation of the drawing. By the presence of certain characters, allegories, symbols, we can see references to a particular political situation in the Netherlands - the war with the northern provinces of Spain. The message of the graphic is: the Spanish Habsburgs, commissioned by the mission of God, they are able to fight all of the enemies, especially Protestants, with the help of Immaculate and the Franciscans. The main aim of the graphic is to convince the viewer that this will happen and to create in his mind a vision of the new reality. But Spain was in the seventeenth century nothing but a shadow of former itself (in the time of Philip IV the general condition of Spain get worse). That was the reason why they wanted to hold the belief that the empire continues unwavering. The form of this work (graphics), also allowed to export them around the world, and the ambiguity of the symbolic system, its contents relate to different contexts, and as a result, the Habsburgs, not only Spanish, they could promote their strength everywhere. Therefore it was used very well as a single work of propaganda, as well as a part of a broader campaign

ABSTRACT
A coherent light-scattering experiment on an aqueous clay suspension having a concentration that stretches over an extended range was carried on. The far field speckle was recorded in an unconventional manner.
A computer code for image processing, written for this purpose, was used to extract the scattered light intensity. The variation of the average scattered light intensity with the particle concentration was analyzed, and a possible fast procedure for assessing the particle concentration is suggested.
The Dead Sea Ecosystem Influenced by Red Sea – Dead Sea Conduit Project (Peace Conduit)
Authors: Wedyan Moh’d , El-Oqlah Ahmed , Altif Khalil , Khlifate Khalid 
Published: January 2015

ABSTRACT
Recently, the rapid drying out of the Dead Sea is one of the most challenging problems facing the scientists and governments of the region. Its level has dropped more than 20 m in the past decade. Massive precipitation of halite from the water column has led to a decrease in Na+ concentration, concomitant with an increase in Mg2+, making the lake supersaturated with NaCl. This situation presents a big challenge to the microbial life of the lake. However, despite these harsh conditions in the lake, several microorganisms, including members of the groups bacteria, unicellular algae, fungi, viruses, and Archaea, have been able to survive.
To understand the factors that affect the microbes in the Dead Sea and to predict the possible effects of the planned conveyance of Red Sea water to the Dead Sea, a series of experiments were performed in the field, as well as in the laboratory. The results of the laboratory experiments showed that the growth of the Dunaliella was possible only when Dead Sea water was diluted with a minimum of 10% (by volume) Red Sea water. Addition of phosphate was essential for the algae to grow and growth rates and yields increased with increasing phosphate concentration and decreasing salinity. Field experiments revealed that the growth of algae was rapidly followed by the development of dense blooms of red halophilic Archaea. Although it should be realized that the closed system formed by the shallow ponds differs from the conditions in the lake, the results suggest that a microbial bloom, once formed, can remain present in the Dead Sea for months to years. These observations are important when attempting to predict how the biological properties of the lake may change in the future and they have important implications for the planning of the Red Sea- Dead Sea conduit.
The “Peace Conduit”, a water carrier between the Red Sea and the Dead Sea, has been proposed to prevent the drying out of the lake and to restore the water level to a desired elevation. The present simulation experiments were designed at the Al Hussein bin Talal University (AHU) field station atMa’an to get information on the ecological impacts of the Dead Sea when the “Peace Conduit” plans are implemented and massive quantities of Red Sea water will enter the Dead Sea and lower the salinity of the upper water layers.
Preliminary analysis was carried out of Fluorescence In Situ Hybridization (FISH) and Polar lipid of Archaea and Bacteria collected from the experimental ponds containing different Dead Sea-Red Sea water ratios, in order to analyze how they affect the microbial communities of the ponds. The Archaea community changed significantly according to the water mixture, presenting the greatest diversity when 30% Red Sea water was added to Dead Sea water.
Climatic Influence on the Phytoplankton Communities of the Upper Reaches of the Southern Bug River (Ukraine)
Authors: Bilous Olena , Barinova Sophia , Klochenko Petro 
Published: January 2015

ABSTRACT
A total of 98 taxa of algae were observed in phytoplankton, sampled monthly, from the Khmelnitsky monitoring station in the Southern Bug River, Ukraine, between April 2010 and March 2011. Chlorophyta species are the richest taxonomic group with 46 taxa, followed by Bacillariophyta, Euglenophyta, Cyanoprokaryota, Dinophyta, Chrysophyta, Streptophyta, and Xanthophyta. Seasonal dynamics of species distribution in taxonomic divisions shows that the role of Bacillariophyta in communities was high in January-March, which were replaced by greens in March-September. Euglenoids were developed in February-December and bluegreen algae in summer communities only. Strong positive correlations between temperature and species richness was observed. Abundance and biovolume of phytoplankton were maximal in summer, caused mostly by Dolichospermum flos-aquae (Lyngb.) Wacklin, Hoffmann and Komarek and Ceratium hirundinella (O. Müll.) Bergh. The river ecosystem has two periods of trophic levels - high at summer and low at winter. Bioindication characterizes the river as low alkaline and low mineralized with a moderate organic pollution level, revealed aspects of seasonal changes and revealed the main source of organic pollution as flowing from the catchment area during ice melting and rains. Organic pollution indices fluctuate within narrow limits suggesting relative stability of the river ecosystem that is shown also by Shannon indices. The calculated indices, comparative statistics, CCA, and bio-indication analysis exhibits a low pollution level in the Khmelnitsky monitoring station that can be used as a model of aquatic community dynamics under seasonal fluctuation in the southern boreal province climate, applicable for monitoring of the Southern Bug River.
The Economic and Ecological Potential of Macrophytic Vegetation in Urban Lakes
Authors: Irimia-Hurdugan Oriana 
Published: January 2015

ABSTRACT
This paper considers certain elements relating to the ecological and economic importance of the aquatic macrophytes common in the Câmpia Română/Romanian Plain lakes, especially those species belonging to the genera Myriophyllum and Potamogeton, common in Bucharest’s urban lakes. At present, the macrophytes of the Bucharest lakes are collected by personnel of the Lakes, Parks and Leisure Administration of Bucharest by mechanised and manual methods, which are sun-dried and transported as waste and deposited in a landfill. Thus these macrophytes are merely generating costs through harvest, transport and storage, instead of being a direct revenue source for the City hall. This study presents a review of international literature in support of the economic potential as fertiliser for open field crop, orchard and garden crop application, as well as food for farm animals. The last portion of the paper argues the vital need for the preservation of macrophyte stands in the lacustrine habitat for green, sustainable and integrated management of the urban lakes used for leisure and fishing.
Long- and Short-Term Changes of the Structure of Macrophytes in Lake Piaseczno in Relation to Land Use in the Łęczna-Włodawa Lakeland (Poland)
Authors: Sender Joana , Maślanko Weronika 
Published: January 2015

ABSTRACT
The Łęczna-Włodawa Plain, known also as the Łęczna-Wlodawa Lakeland, lies within the territory of the largest subregion of the Polesie region, covering over 1,300 km2. The main interest of the Łęczna-Włodawa Lakeland is that it is the oldest in the Central European Lowlands group of about 68 lakes. Among such a large number of lakes there exist all trophic types. However, since the late 1950’s, enormous dynamics of change associated with the disappearance of oligo- and mesotrophic lakes and their transformation into eutrophic, even hypertrophic, lakes have been observed. One of the biocenotic elements of the lakes, which are indicators of these changes, is aquatic plants. The aim of this study was to determine the macrophyte structure of Piaseczno Lake and changes of land use in its surroundings. Piaseczno Lake still represents very high natural values. A reduction in the number of macrophyte communities, which occurred especially in 2008, was a consequence of the fast-growing recreation infrastructure.
From 1976 until 2010 an area of recreation infrastructure in the studied area increased more than 3.5 times, and in the built-up area more than five times, as well as a doubling of the total length of the roads. Meanwhile the surface area of wetlands and peatbogs significantly decreased - more than 11 times.
Long-term changes in the structure of the macrophyte communities show that the number of communities has varied in each year, probably as a consequence of changes in landuse. Analysis showed changes to the surfaces inhabited by macrophytes, which have decreased significantly over only four years, by more than 25%. However, the proportion of rush communities has increased.
Analysis of the Microsatellite Variation in the Common Hybrid Between Russian Sturgeon (Acipenser Gueldenstaedtii Brandt and Ratzeburg, 1833) and Siberian Sturgeon (Acipenser Baerii Brandt, 1869) from Aquaculture

Published: January 2015

ABSTRACT
Sturgeons such as Acipenser baerii and Acipenser gueldenstaedtii are the most common species farm raised worldwide in aquaculture, because of the dwindling natural sources of caviar and meat. Also, these species can easily participate in the formation of an intraspecific hybrid with a great potential for growth in aquaculture.
Microsatellites are nuclear markers consisting of short repetitive sequence, dispersed across the entire genome with characteristics such as relatively small size and high level of polymorphism. The aims of the present study were to optimize a protocol for microsatellite multiplexing and analysis of genetic diversity in hybrid sturgeons farmed in Romania.
Genomic DNA was isolated from fins, and four pairs of primers were designed to amplify microsatellite loci: LS 19, LS 68, Aox 9, and Aox 45. Amplification of the microsatellite loci was carried out in one 3-Plex reaction for LS 19, LS 68, and Aox 9, and monoplex reaction for Aox 45. For an individual locus we obtained four alleles for Aox 45, eleven alleles for Aox 9, six alleles for LS 68, and eight alleles for LS 19. The results will be applied to test the broodstocks at Romanian hatcheries and to increase the efficiency of breeding.

ABSTRACT
Among the species of salmonids that exist in Romania, the most common is the brown trout (Salmo trutta, morpha fario, Linnaeus, 1758), with a high commercial potential, being used for aquaculture or fishing. Unfortunately, its natural habitat is disrupted by human activities and in order to avoid local extinction of Salmo trutta fario repopulation strategies are being applied. The repopulation activities must be carefully designed and conducted taking into consideration that there is a high risk of hybridization. Our study aims to analyze the genetic diversity of three Romanian brown trout populations found in rivers in the Făgăraş Mountains using mitochondrial markers.
Standard DNA extraction protocol with phenol-chloroform was applied to the biological material represented by small fin fragments sampled from 80 individuals of brown trout, followed by PCR amplification of D-loop control region and Sanger sequencing. Alignment and editing of all the sequences obtained were carried out with Bioedit, the phylogenetic tree construction was performed by Neighbour Joining method implemented in MEGA v5, and intra- and interpopulational diversity was evaluated with DNAsp v5 and MEGA v5.
For the three brown trout populations, 13 haplotypes were identified for N1, 11 for N2 and 10 for N4, with a haplotype diversity greater than 0.8. The phylogenetic tree topology showed that individuals chosen for this study were placed in the Danubian clade as the other Danubian sequences selected from GenBank.
The study proved that the three Salmo trutta fario populations analyzed were genetically distinct and that in Romania there are still are pure Danubian brown trout populations.
