    Since 1988, the company ZTS VVU KOSICE has devoted a great part of its activities to the development of equipment for RAW handling, packaging, transport and storage, mainly for application in the decommissioning of NPP A1 at Jaslovske Bohunice in Slovakia. This is a HWGCR NPP shut down following a breakdown in 1977. This incident was caused by disruption of the technological channel serving as a barrier between heavy water moderator and fuel assembly. Damage of this barrier enabled heavy water leakage into the primary circuit with partial fuel elements cladding damage and subsequent additional contamination of the primary circuit. During two consecutive years after the incident main effort was focused on activities related to personnel and environment protection, moderator draining, reactor defuelling, dry cleaning of the primary circuit, repair and maintenance of equipment. The next step was the preparation of the concept of NPP A-1 introduction into dry safe state. The order of importance of RAW liquidation was as follows: 1. Spent fuel - spent fuel assemblies from NPP A-1 were, after short cooling, stored temporarily in storage pipe containers filled at the beginning of NPP operation with ''chrompik'' (an aqueous solution of K 2 Cr 2 O 7 with concentration of 3-5%), later with ''dowtherm'' (mixture of bi-phenyl oxide and bi-phenyl). The containers were placed in a storage pond filled with water. 2. Liquid RAW - combustible (dowtherm, oils) and non-combustible (chrompik, Demi water, decontaminating solutions, sludge, sorbents, etc.) 3. Solid RAW - metallic and non-metallic For this purpose, it was necessary to build RAW processing lines, intermediate storage facilities and systems for manipulation and transport of RAW

    Meteorite Kosice fell down 28 th of February 2010 near the Kosice and represents an unique find, because the last fall of meteorite was observed in Slovakia at the year 1895. It supposes that for this kind of meteorite the orbit in cosmic space could be calculated. This is one of most important part because until now 13 places of meteorite find are known in the world of which cosmic orbit in space have been calculated. Slovakia is member of international bolide net, dealing with meteorite analysis in Middle Europe .Analysis of Kosice meteorite will also concern at the long live and short live nuclides. Results should be a contribution to determination of radiation and formative ages. From structural analysis of meteorite it will be possible to compare it with similar types of meteorites. In this work Moessbauer spectroscopy will be used for phase analysis from point of view iron contain components with the aim to identify magnetic and non magnetic fractions. From the analysis of magnetic part we can find that the first sextet with hyperfine magnetic field 33.5 T corresponds to bcc Fe-Ni alloy (kamacite) and second with field 31.5 T to FeS (triolite). Meteorites with mentioned composition belong to the mineral group of chondrites. Comparing our parameters with results of measurements at the similar meteorites we can conclude that Kosice meteorite contains the same components. According all Moessbauer parameters we can also include this meteorite in the mineral group of chondrites. (authors)

    Replacing political nominees at state-owned companies after each change of the cabinet has become a standard. The consequences are all too well-known. In the best case, the company gets a manager that is an expert in the given area and in the worst case the new manager is a person who does not have the vaguest idea of the business and the only reason he has taken the position is to collect the salary. And in addition to this they might harm the company due to a lack of experience and expertise. These post-election changes often remove capable people from company management that do not have friends in the new cabinet but do not wish to leave the business. Over the years, they gained experience so why not start up a new company in the same business area. And heat supply in Kosice is a good example. For many years, there was only one heat supplier in Kosice, the state-owned joint stock company Teplaren Kosice (TEKO). It uses natural gas and coal from Russia. But at the end of last year, a new private limited liability company, Teplarenska spolocnost, was established. And it plans to build a new heating plant using wooden bio-mass for about 300 mil. Sk (8.82 mil. EUR) to compete with TEKO. The owners and managers of the company include former employees of the state-owned heating plant. (author)

    Meteorite fall was observed by the town Kosice in Slovakia in February 2010. The fall itself was imaged by three security video cameras from Hungary. Detailed bolide light curves were obtained through clouds by radiometers on seven cameras of the European Fireball Network. Records of sonic waves were found on six seismic and four infrasonic stations. chondrites in various works. Due to the high abundance of iron in the solar system and its chemical and physical properties, we can gain insight into the formation and evolution of planets through the study of iron compounds in the planetary bodies. These kinds of analyses can bring important knowledge about phases and compounds formed in extraterrestrial conditions, which have another features than their terrestrial analogues. The "5"7Fe Moessbauer spectroscopy is one of the most sensitive methods for such studies. In this work Moessbauer spectroscopy will be used for phase analysis of iron bearing compounds with the aim to identify magnetic fractions using magnetic separation. (authors)

    Pitch programming is only realizable in the non-ideal case and as such is tried on ZT-S. Once the resistivity profile in the plasma is determined along with the appropriate thermal conductivity, then q(t) at the wall possesses a fairly simple mapping to a q(r) for a given time as shown in the experimental results. Thus the resulting q(r) profiles are qualitatively similar to ones desirable from the point of MHD stability theory. The results of this initial investigation indicate that pitch programming should be pursued further as a possible means of setting up desirable equilibrium profiles in an RFP

    Robots that stack magnets weighing several tons in the world's biggest nuclear laboratory with a millimetre precision. Small machines that can destroy bombs, detect bombs in trains, planes or cars. A leading position in an expert group that, with NATO funds, tests how robotic systems can be used in the fight against terrorism. This summary indicates that ideas are an integral part of the work done at the ZTS Vyskumno-vyvojovy ustav (ZTS VVU) research institute in Kosice. This is nothing special for a research institute. But this is a joint stock company. And so it needed one additional vision: producing goods that sell from the research. ZTS VVU has delivered robotic system for accurate positioning of cryo-magnets for the CERN. Cryo-magnet is 16 m long and weights 34 tonnes. For the CERN five robotic systems were delivered. The value of the contract with the CERN was about 60 millions slovak crowns (≅ 2 million EUR). Transport containers, manipulators for decontamination and manipulators with radioactive wastes were manufactured for the Bohunicke spracovatelske centrum (Bohunice Radioactive Waste Processing Center).

    Single crystals of pure and L-aspartic acid doped Zinc (Tris) Thiourea Sulphate (ZTS) were grown from aqueous solution by solution growth method. The cell parameters and structure of the grown crystals were determined by X-ray diffraction studies. The presence of functional group in the compound has been confirmed by FTIR and FT-Raman analysis. The optical transparency range has been studied through UV-Vis spectroscopy. TGA/DTA studies show thermal stability of the grown crystals. Microhardness study reveals that the hardness number (Hv) increases with load for pure and doped ZTS crystals. Dielectric studies have been carried out and the results are discussed. The second harmonic generation was confirmed for L-aspartic acid doped ZTS which is greater than pure ZTS.

    Highlights: •The influence of MgSO{sub 4} doping on the properties of ZTS single crystals grown at room temperature. •Thermal stability of the crystals increased with incorporation of Mg atom. •Energy band gap was estimated from UV–vis spectra. •ZTS is a potential material for frequency conversion. •Both pure and doped ZTS crystals are belonging to category of typical insulating materials. -- Abstract: The influence of MgSO{sub 4} doping on the properties of zinc tris–thiourea sulphate single crystals grown at room temperature by slow evaporation solution growth technique was studied. Powder XRD analysis confirmed the orthorhombic crystal structure with noncentrosymmetric space group Pca2{sub 1}. The mechanical properties of the grown crystals were analysed by Vicker’s microhardness method. Functional groups present in the materials were identified by FTIR spectral analysis in the range between 4000 and 400 cm{sup −1}. The UV–Vis spectrum indicates that the UV cut-off wavelength of the crystals has less than 297 nm. The thermal stability of the grown crystals was determined with the aid of thermo-gravimetric analysis (TGA) and differential scanning calorimetry (DSC). Second order nonlinear optical behaviour of the grown crystals have been confirmed by Kurtz powder second harmonic generation (SHG) test.

    Diagnostic and therapeutic application of ionising radiation is very important in all of branches of medicine including veterinary medicine. In veterinary training at University of Veterinary Medicine in Kosice (UVM), biophysics is a basic subject and it grants physical basis necessary for understanding subsequent subjects such as veterinary surgery, roentgenology, orthopedics. In view of this, traditional methods of radiology such as fluoroscopy, skiagraphy and tomography are explaining. The appearance and application of the theory so called reconstruction of image and also computers led to qualitatively new solutions via the development of modern methods in radiology. Explaining of physical principles, advantages or disadvantages of these new methods is also important in veterinary training although some of them do not use in veterinary practice yet. Two modern methods of nuclear medicine using in diagnostic (SPECT and PET) are discussed bellow. (authors)

  17. The Kosice meteorite fall: atmospheric trajectory and fragmentation from videos and radiometers

    2012-01-01

    On 28 February 2010, 22h24m46s UT, a huge bolide of absolute magnitude -18 appeared over eastern Slovakia. Although this country is covered by the European Fireball Network (EN) and the Slovak Video Network, bad weather prevented direct imaging of the bolide by dedicated meteor cameras. Fortunately, three surveillance video cameras in Hungary recorded, at least partly, the event. These recordings allowed us to reconstruct the trajectory of the bolide and recover the meteorites. In addition, the light curve of the bolide was recorded by several EN camera radiometers, and sonic booms were registered by seismic stations in the region. The meteorites were classified as ordinary chondrites of type H5 (see Meteoritical Bulletin 100). I developed a model of atmospheric meteoroid fragmentation to fit the observed light curve. The model is based on the fact that meteoroid fragmentation leads to a sudden increase of a bolide's brightness, because the total meteoroid surface area increases after the fragmentation. A bright flare is produced if large numbers of small fragments or dust particles are released. I tried to model the whole light curve rigorously by setting up the mass distribution of fragments and/or dust particles released at each fragmentation point. The dust particles were allowed to be released either instantaneously or gradually. The ablation and radiation of individual particles were computed independently, and the summary light curve was computed. The deceleration at the end of the trajectory was taken into account as well. Based on the approximate calibration of the light curve, the initial mass of the meteoroid was estimated to 3500 kg (corresponding to diameter of 1.2 m). The major fragmentation occurred at a height of 39 km. Only few (probably three) large compact fragments of masses 20-100 kg survived this disruption. All of them fragmented again at lower heights below 30 km, producing minor flares on the light curve. In summary, Kosice was a weak

    The aim of this study was to investigate a possible influence of occupational exposure to carcinogenic environmental polycyclic aromatic hydrocarbons (c-PAHs) on cellular susceptibility to the induction of the DNA damage. Monitoring was performed and blood samples were collected from two groups of male subjects: occupationally exposed and matched controls. The group exposed to c-PAHs (average age of 35.1 years) consisted of 52 policemen from Kosice and 26 policemen and 25 bus drivers (51 altogether) from Sofia. The control group (average age of 36.4 years) consisted of 54 unexposed subjects from Kosice and 24 from Sofia. In the investigated groups 52.5% of exposed subjects and 45.3% of control were current smokers. A challenging dose of X-rays (3 Gy) and an alkaline version of the single cell gel electrophoresis (SCGE) assay, known as Comet assay, were used to evaluate levels of induced DNA damage and repair kinetics in isolated human blood lymphocytes. DNA damage detected in lymphocytes prior to or after irradiation did not differ significantly between exposed and unexposed subjects. A significant decrease in repair efficiency due to exposure to PAHs was observed in the exposed individuals from Kosice and Sofia, when analysed separately or together. A negative influence of tobacco smoking on the efficiency of DNA repair was observed. Statistically significant differences were found between subgroups stratified according to education level in Sofia: the half times for DNA repair declined with the increasing level of education. These results confirm that environmental exposure to c-PAHs can alter the ability of blood lymphocytes to repair DNA damage and, as a result could potentially lead to effects that are hazardous to human health.

    At present, climatic changes are the most important and urgent worldwide problems. They are a real and rising threat to the environment. An intensive climatic research and monitoring yielded a better knowledge about the reasons and effects of global warming. Global warming in the range of 1.4 to 5.8 {sup o}C affects weather, year seasons, ecosystems, water sources, health of citizens, as well as global and domestic economy. Nowadays, it is clear that the climatic instability is mostly caused by human activities. 21% of total carbon dioxide (CO{sub 2}) emissions in Europe comes from traffic, which is one of the biggest sources of greenhouse effect gases and rises up to 2.5% every year. A main reason is the increasing automobile and airplane transport.

    The scaling properties of a toroidal reversed-field Z pinch have been investigated over a limited range by comparing two experiments having conducting walls and discharge-tube minor diameters which differ by a factor of approximately 1.5. Both the confinement time of the plasma column and the electron temperature were found to increase about a factor of two with the increased minor diameter. Both the poloidal field diffusion and the decay of the toroidal reversed field were significantly reduced with the larger tube diameter. These results support the hypothesis that the loss of stability later in the discharge is caused by diffusion-induced deterioration of initially favourable plasma-field profiles to MHD unstable ones. This conclusion has been verified by stability analysis of the magnetic field profiles. Fusion reactor calculations show that small reactors are conceptually possible assuming good containment can be achieved for current densities approximately >20MAm -2 . (author)

    1979-01-01

    The determination of the absolute energy loss due to radiation from impurities in the LASL toroidal reversed-field pinch experiment ZT-S is reported. The measurements show that over half the energy loss is accounted for by this mechanism. Thomson-scattering electron density measurements indicate only a gradual increase in temperature as the filling pressure is reduced, indicating an increased energy loss at lower pressures. Cylindrical and toroidal simulations of the experiment indicate either that a highly radiative pinch boundary or anomalous transport is needed to match the experimental results. New effects on the equilibrium due to plasma flows induced by the toroidal geometry are predicted by the toroidal simulations. The preliminary results on the low-temperature discharge cleaning of the ZT-S torus are reported. A description of the upgrade of the ZT-S experiment and the objectives, construction and theoretical predictions for the new ZT-40 experiment are given. (author)

    Full Text Available Recycling nutrients form sanitary wastes back into agricultural ecosystems offers an option to alleviate soil depletion in regions where the use of mineral fertiliser is limited. Exemplary nutrient and water cycling approaches, including collection, treatment and use of human urine, are established at Valley View University (VVU in Greater Accra, Ghana.Concerns have been recently raised in regard to fate and impact of pharmaceutical residues in soils and interlinked environment. To evaluate in how far emerging knowledge can be transposed onto VVU, urban and rural environments in Greater Accra, spatial disease occurrence and drug consumption patterns were studied. Malaria has been found to represent the most severe health burden in Ghana, but there is also a high prevalence of infectious diseases. Drugs consumed in great quantities and in respect to their residual loads potentially problematic in the environment belong to therapeutic groups of: antibiotics, analgesics, drugs for diabetes, antimalarials, cardiovascular drugs and anthelmintics. Drug consumption revealed to be highest in urban and lowest in rural areas. At VVU the range of consumed drugs is comparable to urban areas except for the negligible use of diabetes and cardiovascular medication as well as contraceptives.

    Satellite DNA is a characteristic component of mammalian centromeric heterochromatin, and a comparative analysis of its evolutionary dynamics can be used for phylogenetic studies. We analysed satellite and satellite-like DNA sequences available in NCBI for 4 species of the family Canidae (red fox, Vulpes vulpes, VVU; domestic dog, Canis familiaris, CFA; arctic fox, Vulpes lagopus, VLA; raccoon dog, Nyctereutes procyonoides procyonoides, NPR) by comparative sequence analysis, which revealed 86-90% intraspecies and 76-79% interspecies similarity. Comparative fluorescence in situ hybridisation in the red fox and dog showed signals of the red fox satellite probe in canine and vulpine autosomal centromeres, on VVUY, B chromosomes, and in the distal parts of VVU9q and VVU10p which were shown to contain nucleolus organiser regions. The CFA satellite probe stained autosomal centromeres only in the dog. The CFA satellite-like DNA did not show any significant sequence similarity with the satellite DNA of any species analysed and was localised to the centromeres of 9 canine chromosome pairs. No significant heterochromatin block was detected on the B chromosomes of the red fox. Our results show extensive heterogeneity of satellite sequences among Canidae and prove close evolutionary relationships between the red and arctic fox. © 2017 S. Karger AG, Basel.

    Slovak government will not grant state long-term credit guarantee sized about 1 billion Slovak crowns, which Geoterm, a.s., Kosice company would like to get from World bank. Loan should be used as for construction of geothermal source in village Durkov near Kosice, which would be connected in Kosice thermal plant TEKO, a.s. Geothermal sources capacity after realization of planned investments should reach half of present output of plant. The nearest TEKO investments should head to changes in plant production process. Plant wants to redirect in heat and thermal energy production from existing dominant gas consumption to black coal incineration. Black coal incineration is more advantageous than natural gas exploitation in spite of ecologic loads. TEKO also will lower gas consumption for at least 30 per cent and rise up present black coal consumption almost twice

    We present a case of a 60-year old patient hospitalized at the Department of Infectious Diseases and Travel Medicine, Medical faculty of UPJS and L. Pasteurs University Hospital in Kosice with suspected gastroenteritis. The patient was admitted to an intensive care unit because of the signs of septic shock. Within one hour from admission, the patient was administered early goal directed therapy for septic shock. Subsequently, infectious endocarditis of stimulation electrodes and tricuspid valve was identified as the origin of the infection. The stimulation system was then explanted from a stabilized and afebrile patient at the Department of cardiac Surgery of Eastern Slovak Institute of Cardiac and Vascular Diseases in Kosice. This case should emphasise frequently atypical course of this serious disease and the need for early identification of severe sepsis to enable timely management to affect mortality.

  2. Heating plant overcomes coal crisis

    Sobinkovic, B.

    2006-01-01

    At the last moment Kosice managed to overcome the threat of a more than 30-percent heating price increase. The biggest local heat producer, Teplaren Kosice, is running out of coal supplies. The only alternative would be gas, which is far more expensive. The reason for this situation was a dispute of the heating plant with one of its suppliers, Kimex. Some days ago, the dispute was settled and the heating plant is now expecting the first wagon loads of coal to arrive. These are eagerly awaited, as its supplies will not last for more than a month. It all started with a public tender for a coal supplier. Teplaren Kosice (TEKO) announced the tender for the delivery of 120,000 tons of coal in June. Kimex, one of the traditional and biggest suppliers, was disqualified in the course of the tender. The winners of the tender were Slovenergo, Bratislava and S-Plus Trade, Vranov nad Toplou. TEKO signed contracts with them but a district court in Kosice prohibited the company from purchasing coal from these contractors. Kimex filed a complaint claiming that it was disqualified unlawfully. Based on this the court issued a preliminary ruling prohibiting the purchase of coal from the winners of the tender. The heating plant had to wait for the final verdict. The problem was then solved by the company's new Board of Directors, who were appointed in mid October who managed to sign new contracts with the two winners and Kimex. The new contracts cover the purchase of 150-thousand tons of coal, which is 30,000 more than in the original tender specification. Each company will supply one third. (authors)

    The use of infrared thermography in veterinary medicine has been practiced since at least the 1960's, but it is only now, in approximately the last 5 years, that it has been viewed with a reasonably open mind in the veterinary community at large. One of the reasons is progress in sensors technology, which contributed for an outstanding improvement of the thermal imager parameters. Paper deals with veterinary thermography and with description of applications at the University of Veterinary Medicine in Kosice. (authors)

  5. Disruption of the circadian period of body temperature by the anesthetic propofol.

    2016-01-01

    The circadian time structure of an organism can be desynchronized in a large number of instances, including the intake of specific drugs. We have previously found that propofol, which is a general anesthetic, induces a desynchronization of the circadian time structure in rats, with a 60-80 min significant phase advance of body temperature circadian rhythm. We thus deemed it worthwhile to examine whether this phase shift of body temperature was related to a modification of the circadian period Tau. Propofol was administered at three different Zeitgeber Times (ZTs): ZT6 (middle of the rest period), ZT10 (2 h prior to the beginning of activity period), ZT16 (4 h after the beginning of the activity period), with ZT0 being the beginning of the rest period (light onset) and ZT12 being the beginning of the activity period (light offset). Control rats (n = 20) were injected at the same ZTs with 10% intralipid, which is a control lipidic solution. Whereas no modification of the circadian period of body temperature was observed in the control rats, propofol administration resulted in a significant shortening of the period by 96 and 180 min at ZT6 and ZT10, respectively. By contrast, the period was significantly lengthened by 90 min at ZT16. We also found differences in the time it took for the rats to readjust their body temperature to the original 24-h rhythm. At ZT16, the speed of readjustment was more rapid than at the two other ZTs that we investigated. This study hence shows (i) the disruptive effects of the anesthetic propofol on the body temperature circadian rhythm, and it points out that (ii) the period Tau for body temperature responds to this anesthetic drug according to a Tau-response curve. By sustaining postoperative sleep-wake disorders, the disruptive effects of propofol on circadian time structure might have important implications for the use of this drug in humans.

  6. Is Mirko M. Kosić predicted the Great War in 1914?

    2014-01-01

    Full Text Available This paper answers the question which was raised in one of the posts of Jovica Trkulja, actually in one of his statements according to which Mirko Kosic predicted the war in 1914. The mentioned question had in the first place opened several more questions. Is it actually possible to predict anything in the science especially in social science? If it is possible what dose it imply? Eventually, keeping all that in mind did Mirko Kosic really predict the war in his papers 'Panermenism' and 'Modern Germany' according to Trkulja? Taking into consideration the thesis about structural symmetry of explanation and prediction as well as the characteristic order of social reality, then the answer is affirmative. Therefore, it can be said that the whole century after the Great War the legacy of domestic sociology but the pride of the science in general as well. Above all, with this paper Mirko M. Kosic is established as a paradigm of thinking and readiness for a sociologist to abandon the research conformism.

    {sup 57}Fe Moessbauer spectroscopy was used as an analytical tool in the investigation of iron containing compounds of two meteorites (Rumanova and Kosice) out of total of six which had fallen on Slovak territory. In the magnetic fraction of the iron bearing compounds in the Rumanova meteorite, maghemite, troilite and Fe-Ni alloy were identified. In the non-magnetic fraction silicate phases were found, such as olivine and pyroxene. The paramagnetic component containing Fe{sup 3 + } ions corresponds probably to small superparamagnetic particles. The Kosice meteorite was found near the town of Kosice in February 2010. Its magnetic fraction consists of a Fe-Ni alloy with the Moessbauer parameters of the magnetic field corresponding to kamacite {alpha}-Fe(Ni, Co) and troilite. The non-magnetic part consists of Fe{sup 2 + } phases such as olivine and pyroxene and traces of a Fe{sup 3 + } phase. The main difference between these meteorites is their iron oxide content. These kinds of analyses can bring important knowledge about phases and compounds formed in extraterrestrial conditions, which have other features than their terrestrial analogues.

    The paper presented deals with behavior of the radon in geological medium and with some results of the radon survey in Bratislava and Kosice regions. 1) The a{sub v} has been detected in the holes 0.80 m deep. The density of observations - 3 reference areas (one represents 20 stations) per 1 km{sup 2}. The radon risk maps in 1:25000 and 1:50000 scales have been compiled. The 56.8% of the project area lies in low radon risk, 37.6% in medium radon risk and 5.6% in high radon risk. Follow-up monitoring of the equivalent volume radon activity (EVRA) at the flats, located in the areas with high radon risk of the surface layer, has showed values several times higher than Slovak limits (Marianka, Raca, Vajnory). The evidence that neotectonic is excellent medium for rising up emanation to the subsurface layer, is shown on the map. The tectonic zone of Liscie udolie in Bratislava-Karlova Ves area has been clearly detected by profile radon survey (a{sub v} > 50 kBq/m{sup 3}). 2) At present, northern half of the area of Kosice in question was covered by radon survey. The low and medium radon risks have been observed here, while localities with high radon risk are small in extent. The part of radon risk and soil permeability map from northern Kosice area is shown.

    2014-01-01

    Harman method is a rapid and simple technique to measure thermoelectric properties. However, its validity has been often questioned due to the over-simplified assumptions that this method relies on. Here, we quantitatively investigate the influence of the previously ignored parasitic thermal effects on the Harman method and develop a method to determine an intrinsic ZT. We expand the original Harman relation with three extra terms: heat losses via both the lead wires and radiation, and Joule heating within the sample. Based on the expanded Harman relation, we use differential measurement of the sample geometry to measure the intrinsic ZT. To separately evaluate the parasitic terms, the measured ZTs with systematically varied sample geometries and the lead wire types are fitted to the expanded relation. A huge discrepancy (∼28%) of the measured ZTs depending on the measurement configuration is observed. We are able to separately evaluate those parasitic terms. This work will help to evaluate the intrinsic thermoelectric property with Harman method by eliminating ambiguities coming from extrinsic effects

    Baker, D.A.; Machalek, M.D.

    1977-08-01

    A next-generation, toroidal, reversed-field Z-pinch experiment to be constructed at LASL is proposed. On the basis of encouraging ZT-I and ZT-S experimental results, a larger device with a 40-cm bore and a 114-cm major radius is proposed, to extend the confinement time by about an order of magnitude. The new experiment will explore the physics of programming reversed-field pinches in a size range unexplored by previous reversed-field pinch experiments. Model reversed-field pinch reactor calculations show that, if stability is assumed, small fusion reactors are possible if the pinch current density is high. A basic aim will be to delineate the plasma and current density ranges in which stable reversed-field pinches can be produced. Improved vacuum techniques will be used to overcome the radiation losses that probably kept electron temperatures low in the earlier, smaller experiments

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

The biggest known uranium reserves in Central Europe at Jahodna close to Kosice have caused a dispute between the private investors, the municipality and civic societies. The intention of the Canadian company, Tournigan Gold, or rather its Slovak subsidiary, Kremnica Gold, to start a geological survey raised objections from activists and local officials. The aim of the Canadian company is, at least at first glance, obvious: to benefit from international uranium prices. Over the last few years prices have risen by 1600% and the prices of privately owned mining companies has increased up by hundreds of percent. But the reasons behind the objections are also easy to guess: prevent potential environment devastation. There is not much information available on the Jahodna project. Not even Tournigan has it. Executive director Mike Mracek does not yet know the answers to the questions the locals and the municipality are concerned about the most. And so we can only speculate about how the mining waste will be disposed of and what impact mining would have on the city's recreational area. The only thing that is certain is that about 3.6 million tons of uranium-molybdenum metal with a high uranium concentration are present underground. The uranium concentration is about twice as high as in the Czech Republic and four-times higher than a level considered to be profitable. Although Jahodna is a common topic of discussions, realisation is still far away. Kremnica Gold has a permit for a geological survey and a pre-emotive right to mine. Even if it managed to get all the necessary documents to start mining in Kosice mining could not start earlier than in 6 years' time. Kremnica Gold has not yet prepared the relevant economic calculations. But it is certain that under current price conditions it would be profitable to start mining even given the high technology

    Osteomyelitis is defined as an inflammation or infection in bone tissues - cancellous bone, bone marrow, bone compacta and periosteum due to invasion of infection from surrounding tissues. Maxillary osteomyelitis is less common disease than osteomyelitis of mandible. This can be explained by anatomical structure of maxilla which is mainly composed of sinuses and thin bone lamellae. Such a structure allows rapid propagation of the infection to the surface. There have been examined and treated 70 patients with osteomyelitis of facial bones within past 15 years at Department of stomatology and maxillo-facial surgery of P.J. Safarik University in Kosice. Only four cases were diagnosed as maxillary osteomyelitis. The aim of this study was to mention the differences in anatomy and symptoms of acute and chronic stage of maxillary osteomyelitis and to give a detailed radiographic picture of this affliction.

    Slovak air protection legislation is fully identical with the relevant EU legislation. The results of air pollution monitoring in Slovakia in 2004 are summarised in the presented report. The territory of Slovakia was partitioned into 8 zones (identical with administrative counties) and 2 agglomerations (the largest towns Bratislava and Kosice). In 2004 were specified 17 areas with controlled air quality, which totally include 2 774 km 2 and 1 460 000 inhabitants (27 % of population). The Slovak Hydrometeorological Institute (SHMU) maintains national air pollution monitoring network in Slovakia. In 2004, it consisted of 29 real-time monitoring stations, 6 real-time ground level ozone monitoring stations only and 5 regional background stations. The monitoring network was built in accordance with the rules given in EU directives. Only reference or equivalence measuring methods are used. (authors))

    Full Text Available This is a presentation of the application of surveying principles used in a process of building the electrolytic tinning line at the U.S.Steel s.r.o. Kosice. The work involved is setting up a new network of measuring points, as well as the effective implementation of suitable methodologies, instruments and measuring tools. All of these were focal points for the survey, required during the installation of machinery units for the new tinning line. The coil producing technology utilised on the line entails a high speed movement. In this context all methods and final measurements were adapted to a very high standard of precision in order to ensure a safe working environment and exclude the risk of malfunctions in the final production stage. The smallest variations in the positioning of machinery units, compared with technical drawings, could rise a danger of coil breakdown, line malfunction or personal injury.

    The certified, information, and other values of elemental contents were compared with results of neutron activation analysis (NAA) for the new Czechoslovak botanical reference materials (RMs) Green Algae 12-02-02, Lucerne 12-02-03, Wheat Bread Fluor 12-02-04, and Rye Bread Flour 12-02-05. These were prepared by the Institute of Radioecology and Applied Nuclear Techniques (IRANT), Kosice, and statistically evaluated after interlaboratory comparisons. For the majority of elements, a very good agreement was found between the IRANT values and the results of NAA. In several cases, however, significant differences were detected; possible analytical reasons for the differences and the suitability of a purely statistical evaluation of intercomparison results without analytical considerations for RM certification are discussed.

    Full Text Available Today precipitation water in the majority of built up and other sealed surface areas no longer reach the water circulation system via natural routes. This can lead to long-term changes to the soil and water resources, reduce the natural local regeneration of the groundwater and have effects on the chemical and biological conditions above and below the ground surface. Reasonable rainwater management leads to maintain or recover a sound and sustainable water cycle. The purpose of this paper is to present objectives and monitoring of a drainage project in Eastern Slovakia, in Kosice city. The paper focuses on percolation facilities in the research area of campus of Technical University and measurements connected with rainwater infiltration.

    Liberalisation of the electricity market pushes Slovak distribution companies to upgrade their sale technologies. The first one to invest into a complex electronic sales system will be Stredoslovenska energetika, a.s., Zilina. The system worth 200 million Sk (4,83 million Euro) will be supplied by Polish software company Winuel. The company should also supply a software that would allow forecasting and planning of sales. The system should be fully operational by 2006. TREND has not managed to obtain information regarding plans Zapadoslovenska energetika - the largest and most active distribution company - might have in this area. In eastern Slovakia distribution company Vychodoslovenska energetika, a.s., Kosice has also started addressing this issue. (Author)

    The EXPAH project was a molecular epidemiology study whose aims were to evaluate the hypothesis that polycyclic aromatic hydrocarbons (PAHs) are a major source of genotoxic activities of organic mixtures associated with air pollution. Biomarkers of exposure, effects and susceptibility, and oxidative DNA damage were measured in three PAH-exposed populations from Prague (Czech Republic), Kosice (Slovakia) and Sofia (Bulgaria). Control populations were included from each city. In total 356 individuals were enrolled. A questionnaire was used to determine life style/dietary factors. Ambient air exposure was measured by stationary monitoring, and personal exposure monitoring was also carried out. The characteristics of the population are described in this paper together with their personal exposure to carcinogenic PAHs (c-PAHs). The dose of c-PAH exposure was found to vary between the occupationally exposed (e.g. policemen and bus drivers) and the control populations in each country, and also varied from country to country.

    The annual report of SE, a. s., contains information for the year of 2003 and summarises SE's most important financial data for the stated period. The joint stock company Slovenske elektrarne, a. s. (Slovak Power Plants) was established on January 21, 2002, when it was entered into the Commercial Register as a new business entity formed by splitting the former Slovenska elektrarne, a. s. (SE, a. s.) into three independent business entities: Slovenska elektrarne, a. s. (SE, a. s.), Slovenska elektrizacna prenosova sustava, a. s. (Slovak Transmission Grid), and Teplaren Kosice, a. s. (Heating Plant Kosice). Data regarding electricity and heat generation and operational and financial results of the company are stated for the year of 2003, without providing a comparison to the previous year. The reason is that 2002 data do not cover the whole year, as the new SE a. s. was established on January 21, 2002 with changed mix of heat and electricity generation assets. Comparison data for previous years are provided only for certain technical parameters regarding nuclear safety, environment and human resources.

    The sale and purchase of carbon dioxide emissions used to be a topic only of interest to environmentalists - until it started to be about money. Industrial associations in Western Europe started fighting for higher quotas earlier than in Slovakia. Initially, Slovak companies were satisfied with the quotas proposed as these did not force them to decrease production, or invest extensively in more environmentally friendly production, or purchase emission permits for exceeding the quotas set. Everything changed after the European Commission approved the Slovak plan in autumn last year. This set a limit 14% lower than the original proposal. The largest Slovak producer of carbon dioxide - U.S.Steel Kosice - challenged the new quotas directly at the European Court of Justice in Luxembourg. But other producers also object. 'The decrease is an unfortunate and strategically bad move for Slovakia,' said the Head of the Environmental Department at Slovenske elektrarne (Slovak Electric), Branislav Mihaly. And added that the Ministry of Environment was fully responsible for this situation. 'Including the political responsibility of Minister Laszlo Miklos,' he added. Given a quota reduction of 14%, he considers it very likely that Slovak Electric will follow the example of the Kosice steel works. The state must allocate the new quotas before the end of February. The Ministry announced that for large sources, it would seek solutions by individual negotiations. For smaller sources there would be a flat rate decrease. In theory, if companies were to take full advantage of the original quotas, the new allocation plan would cost them 40 to 50 mil. EUR (1.6 -2 bill. Slovak crowns). TREND based its calculation on the current market price of emissions - 8-10 EUR/ton of carbon dioxide

  15. Atmospheric Energy Deposition Modeling and Inference for Varied Meteoroid Structures

    Asteroids populations are highly diverse, ranging from coherent monoliths to loosely-bound rubble piles with a broad range of material and compositional properties. These different structures and properties could significantly affect how an asteroid breaks up and deposits energy in the atmosphere, and how much ground damage may occur from resulting blast waves. We have previously developed a fragment-cloud model (FCM) for assessing the atmospheric breakup and energy deposition of asteroids striking Earth. The approach represents ranges of breakup characteristics by combining progressive fragmentation with releases of variable fractions of debris and larger discrete fragments. In this work, we have extended the FCM to also represent asteroids with varied initial structures, such as rubble piles or fractured bodies. We have used the extended FCM to model the Chelyabinsk, Benesov, Kosice, and Tagish Lake meteors, and have obtained excellent matches to energy deposition profiles derived from their light curves. These matches provide validation for the FCM approach, help guide further model refinements, and enable inferences about pre-entry structure and breakup behavior. Results highlight differences in the amount of small debris vs. discrete fragments in matching the various flare characteristics of each meteor. The Chelyabinsk flares were best represented using relatively high debris fractions, while Kosice and Benesov cases were more notably driven by their discrete fragmentation characteristics, perhaps indicating more cohesive initial structures. Tagish Lake exhibited a combination of these characteristics, with lower-debris fragmentation at high altitudes followed by sudden disintegration into small debris in the lower flares. Results from all cases also suggest that lower ablation coefficients and debris spread rates may be more appropriate for the way in which debris clouds are represented in FCM, offering an avenue for future model refinement.

    Full Text Available In the contribution, methods of separating metals – Fe, Al, Ge from energetic wastes – fly ashes are presented along with further possibilities of utilization of particular valuable components for industrial purposes.In the contribution, properties of energetic wastes are presented influencing the contents, separability, and utilizability of metal-bearing valuable components. From among physical properties these are grain size distribution and surface area. Chemical properties are characterized by elements contained in combusted coal whose content after combustion is increased 2 to 4 times, depending on the content of ash and combustible matters in original coal. Mineralogical properties of energetic wastes are determined by the combustion process conditions in the course of which mineral novelties are produced in concentrations suitable for separation.In the contribution, methods of separation and utilization of metals such as Fe, Al, Ge are described. From literature information on the processing of Fe component, as well as from results of experiments made at the Department of Mineral Processing and Environmental Protection, Technical University of Kosice follows that the highest concentration and mass yield of the component can be obtained from black coal fly ashes produced in smelting boilers. The content of Al in Slovak energetic wastes is lower than the 30 % Al2O3 limit that conditions an economic technological processing. Only in the case of black coal fly ash from TEKO Kosice and EVO Vojany was the Al2O3 content of 32.93 %. Therefore, in an indirect way – by separating the residues of uncombusted coal and magnetite Fe – the content of Al in fly ash was increased.For Ge, a principle of selective sizing has been utilized.A complex utilization of energetic wastes, that is the separation of metallic components, elimination of particular metals and the subsequent treatment of nonmetallic residue, should be an effective solution in various

    Slovensky plynarensky priemysel (SPP) officially indicated that it intended to drop its project of using geothermal energy in the Kosicka kotlina. This spring it published an advert that it was looking for a company that wished to acquire a majority stake in the company, Geoterm Kosice. The company was established to commercially develop this geothermal source. But it seems SPP does not want to drop the project completely. It has kept some important cards, such as control over the land where the boreholes are located Any company that wants to use geothermal energy needs a ruling issued by the Ministry of Environment defining the exploration area. Geothermal sources were found in the villages of Durkov, Svinica, Bidovce and Olsovany. Not so long ago the area was assigned to Geoterm but from May 9 the area can be explored by Slovgeoterm. Both companies have the same majority shareholder - SPP. It controls 96% of Geoterm shares and 50% of Slovgeoterm. So far it has only officially announced its intention to sell the Geoterm shares. But as far as the use of the geothermal resource is concerned since May Slovgeoterm has played a key role.The company focuses on the utilization of geothermal energy. In addition to the project in the Kosice region, it has also participated in a project to heat more than a thousand flats using geothermal water in Galanta and a project to heat greenhouses in Podhajske. There are also other geothermal projects running in Presov and Michalovce. Icelandic company, Enex, with the same specialisation controls 28% of the company and a further 20% is owned by the investment group, NEFCO based in Helsinki. Two percent of the company is owned by its general director and the general proxy of Geoterm, Otto Halas. And so without the agreement of this company no-one can start any activities related to the utilization of geothermal energy. (authors)

    Half Heusler alloys are among the most promising materials for thermoelectric generators as they can be used in a wide temperature range and their starting materials are abundant and cheap, the latter as long as no hafnium is involved. For Sb-doped Ti 0.5 Zr 0.25 Hf 0.25 NiSn Sakurada and Shutoh in 2008 have published ZT max  = 1.5 at 690 K, a value that hitherto was never reproduced independently. In this paper we successfully prepared Ti 0.5 Zr 0.25 Hf 0.25 NiSn with ZT max  = 1.5, however, at higher temperature (825 K). As the main goal is to produce hafnium – free half Heusler alloys, we investigated the influence of niobium or vanadium dopants on Ti x Zr 1−x NiSn 0.98 Sb 0.02 , reaching ZTs > 1.2 and thermal-electric conversion efficiencies up to 13.1%. For Hf-free n-type TiNiSn-based half Heusler alloys these values are unsurpassed. In order to further improve our thermoelectric materials our study is completed by electrical resistivity and thermal conductivity data in the low temperature range but also by mechanical properties (elastic moduli, hardness) at room temperature. The electrical properties have been discussed in comparison with DFT calculations.

  20. An experimental approach of decoupling Seebeck coefficient and electrical resistivity

    The Thermoelectrics (TE) has drawn increased attention among renewable energy technologies. The performance of a thermoelectric material is quantified by a dimensionless thermoelectric figure of merit, ZT=S2σT/κ, where S and σ vary inversely each other. Thus, improvement in ZT is not an easy task. So, researchers have been trying different parameter variations during thin film processing to improve TE properties. In this work, tin nitride (Sn3N4) thin films were deposited on glass substrates by reactive RF magnetron sputtering and investigated its thermoelectric response. To decouple the covariance nature of Seebeck coefficient and electrical resistivity for the enhancement of power factor (S2σ), the nitrogen gas pressure during sputtering was reduced. Reduction in nitrogen gas pressure reduced both sputtering pressure and amount of nitrogen available for reaction during sputtering. This experimental approach of combined effect introduced preferred orientation and stoichiometric variations simultaneously in the sputtered Sn3N4 thin films. The scattering mechanism associated with these variations enhanced TE properties by independently drive the Seebeck coefficient and electrical resistivity parameters.

    The recent energy demands affected by the dilution of conventional energy resources and the growing awareness of environmental considerations had motivated many researchers to seek for novel renewable energy conversion methods. Thermoelectric direct conversion of thermal into electrical energies is such a method, in which common compositions include IV-VI semiconducting compounds (e.g., PbTe and SnTe) and their alloys. For approaching practical thermoelectric devices, the current research is focused on electronic optimization of off-stoichiometric p-type Pb{sub x}Sn{sub 1−x}Te alloys by tuning of Bi{sub 2}Te{sub 3} doping and/or SnTe alloying levels, while avoiding the less mechanically favorable Na dopant. It was shown that upon such doping/alloying, higher ZTs, compared to those of previously reported undoped Pb{sub 0.5}Sn{sub 0.5}Te alloy, were obtained at temperatures lower than 210–340 °C, depending of the exact doping/alloying level. It was demonstrated that upon optimal grading of the carrier concentration, a maximal thermoelectric efficiency enhancement of ∼38%, compared to that of an undoped material, is expected.

    Slovak farmers resemble the peasants from the film T he Magnificent Seven . They keep complaining about their fate but consider any innovation as an interference. And that is why they still have not started growing fast-growing wood although the number of heating plants processing bio-mass from forests and fields is growing. Natural gas is expensive and coal creates pollution. Energy from biomass is becoming a good business and also creates new business opportunities - growing the raw material it needs. Such heating plants usually use waste from wood processing companies and Slovak Forests (Lesy SR) has also started deliveries of chip wood from old forests. There are plantations of fast growing wood suitable for heat production of over 500-thousand hectares throughout the EU. This is about 10% of Slovakian's area where the first plantations are also already being set up. The first promising plantation project was launched this spring. And this is not a project launched and backed by a big company but a starting up businessman, Miroslav Forgac from Kosice. He founded his company, Forgim, last winter. Without big money involved and thank to a new business idea he managed to persuade farmers to set up the first plantations. He supplied the seedlings and the business has started with 75 ha of plantations around Trnava, Sala, Komarno, Lucenec, Poprad and Kosice. He is gradually signing contracts with other landowners and next year the area of plantations is set to grow by 1500 ha. Plantations of fast growing trees such as willow, poplar and acacia regenerate by new trees growing out of the roots of the old and from cut trees so from one seedling and one investment there can be several harvests. Swedish willows from Forgim regenerate 20 to 25 years after the first planting. And only then new seedlings have to be purchased. Using special machines that even cut the wood to wood chips the plantations can be 'harvested' every three years. Unlike crops, the fields do not

    In an attempt to reduce our reliance on fossil fuels, associated with severe environmental effects, the current research is focused on the identification of the thermoelectric potential of p-type (GeTe){sub 1−x}(Bi{sub 2}Te{sub 3}){sub x} alloys, with x values of up to 20%. Higher solubility limit of Bi{sub 2}Te{sub 3} in GeTe, than previously reported, was identified around ∼9%, extending the doping potential of GeTe by the Bi{sub 2}Te{sub 3} donor dopant, for an effective compensation of the high inherent hole concentration of GeTe toward thermoelectrically optimal values. Around the solubility limit of 9%, an electronic optimization resulted in an impressive maximal thermoelectric figure of merit, ZT, of ∼1.55 at ∼410 °C, which is one of the highest ever reported for any p-type GeTe-rich alloys. Beyond the solubility limit, a Fermi Level Pinning effect of stabilizing the Seebeck coefficient was observed in the x = 12%–17% range, leading to stabilization of the maximal ZTs over an extended temperature range; an effect that was associated with the potential of the governed highly symmetric Ge{sub 8}Bi{sub 2}Te{sub 11} and Ge{sub 4}Bi{sub 2}Te{sub 7} phases to create high valence band degeneracy with several bands and multiple hole pockets on the Fermi surface. At this compositional range, co-doping with additional dopants, creating shallow impurity levels (in contrast to the deep lying level created by Bi{sub 2}Te{sub 3}), was suggested for further electronic optimization of the thermoelectric properties.

    The organic materials S - 3 - methyl - 5 - nitro - N - (1 - phenylethyl) - 2 - pyridinamine [3- methyl-MBANP] and S - N - methyl - 5 - nitro - N -(1 - phenylethyl) - 2 - pyridinamine [N- methyl-MBANP] belong to a family of compounds based on the 2-(α-methylbenzylamino)-5- nitropyridine molecule and were identified as promising nonlinear optical materials by the powder disk test. Large single crystals were grown from solution for N-methyl-MBANP, which crystallises in a monoclinic space group, and from the melt and solution for 3-methyl-MBANP which crystallises in an orthorhombic space group. Orthoscopic examination of N-methyl-MBANP revealed no dispersion of the dielectric axes unlike the parent molecule and the position of the dielectric axes was correlated with the molecular structure. Preparation of prisms from single crystals of both materials facilitated the measurement of refractive indices in the visible and the near infra-red. The values obtained were correlated with the crystal structure and a Sellmeier equation fitted to each of the dispersion curves. The nonlinear optical properties of both materials were evaluated by use of the Maker fringe technique and phase matched intensities. By means of these two methods, the full nonlinear d ij tensor was obtained for both materials at a fundamental wavelength of 1064nm. The linear electro-optic properties of N-methyl-MBANP were evaluated using a conoscopic experiment and correlated with the crystal structure together with the magnitude of all non-zero elements in the d ij tensor. Separately, the thermal properties of N-methylurea (NMU), 4-nitro-4'-methylbenzylidene aniline (NMBA) and Zinc TrisThiourea Sulfate (ZTS) were evaluated and all correlated with the crystal structure and bonding.

    Germanium mono-chalcogenides have received considerable attention for being a promising replacement for the relatively toxic and expensive chalcogenides in renewable and sustainable energy applications. In this paper, we explore the potential of the recently discovered novel cubic structured (π-phase) GeS and GeSe for thermoelectric applications in the framework of density functional theory coupled with Boltzmann transport theory. To examine the modifications in their physical properties, the across composition alloying of π-GeS and π-GeSe (such as π-GeS1-xSex for x =0, 0.25, 0.50, 0.75, and 1) has been performed that has shown important effects on the electronic band structures and effective masses of charge carriers. An increase in Se composition in π-GeS1-xSex has induced a downward shift in their conduction bands, resulting in the narrowing of their energy band gaps. The thermoelectric coefficients of π-GeS1-xSex have been accordingly influenced by the evolution of the electronic band structures and effective masses of charge carriers. π-GeS1-xSex features sufficiently larger values of Seebeck coefficients, power factors and figures of merit (ZTs), which experience further improvement with an increase in temperature, revealing their potential for high-temperature applications. The calculated results show that ZT values equivalent to unity can be achieved for π-GeS1-xSex at appropriate n-type doping levels. Our calculations for the formation enthalpies indicate that a π-GeS1-xSex alloying system is energetically stable and could be synthesized experimentally. These intriguing characteristics make π-GeS1-xSex a promising candidate for futuristic thermoelectric applications in energy harvesting devices.

    Full Text Available Introduction. Physical activity is an indelible part of human life, but the impact of industrial changes on society has led to a hypokinetic lifestyle not only in adults but also in children and youth. This paper aims to present the results of a study of the body posture of 7-year-olds, which is an essential part of their physical development evaluation. The aim of our study was to expand our knowledge of the occurrence of body posture disorders in 7-year-olds, as well as to develop an appropriate movement programme which would help improve the current situation. Material and methods. The research sample consisted of 393 first-graders from 4 grammar schools in Kosice. We used muscle testing according to Janda and Tichy to obtain data on individual muscle weaknesses and postural deviations. Results. Our research confirmed the findings of several other researchers who had pointed out that muscle weaknesses and postural deviations can be observed already in preschoolers. Due to a lack of physical activity and movement, muscle weakness in preschool children results in more serious health issues at school age and later in adulthood. Conclusions. We managed to stabilise and even to correct the weaknesses we observed by implementing a movement programme focusing on the diagnosed muscle weakness.

    In this paper author deals with privatization of Slovenske elektrarne (SE), a.s. Bratislava and their influence on economy of the Slovak Republic. Country made the first step in privatization in the case of SE at the beginning of 90's by transformation of state enterprise to a. s. with state dominant position (95.8% of stocks was held by Fond narodneho majetku (National Property Fund), the rest was divided between SPP, a.s. and Restitucny investicny fond (Restitution capital fund). In the next phase two newly founded separate a.s. TEKO, a.s. (Teplaren Kosice) and SEPS, a.s. (Slovenska elektrizacna prenosova sustava) were set aside from a.s. Government adopted two basic variants of sale of SE, a.s. stocks by resolution N. 700/2002. Possible variants of SE privatisation are discussed. Energy position of Slovak Republic in European context is relatively favourable in present time because production capacities exceed domestic consumption and part of energy (up to 600 MWh) is exported. Future of thermal power plants Novaky and Vojany is interrogative because of tightened ecological norms, besides Slovak Republic undertook to lay up both blocks of Bohunice NPP V1. Forecasts show that Slovak Republic will stop to be self-sufficient in electric power production about 2010. (Author)

    The etiology of PAOD is the most common cause of disability atherosclerotic arteries. Significantly reduces the quality of life (leading to limb amputation). Chronic renal insufficiency, diabetes and smoking are risk factors for progression of PAOD. In patients with claudication significantly reduced in active life reconstruction is indicated in the form of classical femoropopliteal bypass. Surgery may be supplemented or replaced transluminal percutaneous angioplasty (PTA). The aim of this retrospective study at the Department of Vascular Surgery and LF UPJS VUSCH, a. s. in Kosice in 2008 – 2010 was due to the ambiguous result of several previous studies, analyze and compare the results of the surgical and endovascular revascularisation in patients with peripheral artery disease of the lower extremities in the femoropopliteal region. We found that the use of bypass respectively endovascular angioplasty in patients with infra inguinal disability for 1 year follow-up did not lead to differences in clinical and technical success in primary and secondary patency of blood vessels, or in improving claudication interval between groups. There also were no differences in the need for revascularization or limb amputation within 1 year of performance. Use bypass was associated with a higher incidence of improving symptoms of critical limb ischemia and a higher incidence of hematoma following exercise. (author)

    When information on plans to build a power station in Trebisov first appeared reactions differed. A 40-billion investment in a town with more than 20% unemployment seemed attractive. But some people did not like the idea of having a power plant located in the town. Around one year after the investment was officially announced TREND returned to Trebisov. In the meantime the investor has managed to overcome one of the biggest obstacles on its way to building a new power plant. The ministry responsible gave the environmental study a positive rating. But objectors are still not sure that everything is fine. They claim that the study misinterprets data and that the ministry did not show expertise when evaluating it. 'Is it possible that a coal power plant located in a town would have twice as many positive effects on peoples' health than negative ones? Why don't we build them everywhere?'asked the chairman of the civic society, Trebisov nahlas, Gejza Gore. The developer of the project, Ceskoslovenska energeticka spolocnost (CES), Kosice is fighting back and claims that their counterpart lacks professional arguments. In the meantime it is preparing for area management proceedings. Trebisov is also involved in the discussion and claims that the town planning scheme does not include such a project. The Ministry of Construction has a different opinion. In the opinion of the Ministry the town planning scheme allows a 885-megawatt power plant to be built only a few hundred meters away from housing estates. (author)

    Corus R, D and T at Teesside Technology Centre has developed over a number of years a mould thermal monitoring (MTM) system based on an array of thermocouples in the mould copper plates. The system is installed on the Corus slab casters in the UK, on slab casters at Outokumpu (UK), Sidmar (Belgium) and Kosice (Slovakia) and, at the time of the 4th European Continuous Casting Conference, was also on the medium thickness slab caster at Tuscaloosa (USA), which was sold to Nucor in 2004. The MTM system was also under development on the thin slab caster at Trico (USA) before plant closure (subsequently bought by Nucor), and aspects are currently being developed on the Corus DSP (direct sheet plant) thin slab caster at IJmuiden (The Netherlands). While a prime function is detection and prevention of sticker type breakouts, the MTM system allows real time assessment of thermal conditions, provides a valuable input for online grading and, most important, enables modifications to mould powder practices to be assessed. The present paper briefly outlines recent developments to the MTM system and presents examples of the use of the system to assist mould powder developments. (author)

    Full Text Available FSO technology is a progressive implementation of smart network solutions these days. The link speed, low cost, a fast implementation are just a few advantages of many other. Despite all those strengths there is at least one limitation. It is called weather. The wavelengths values on which FSO operates are quite similar to fog, smoke, snow and dust particles. It is obvious that if those proportions are comparable, it’s not surprising that there will be some interactions among beams and particles. That’s why we decided to investigate the weather influence to a link availability of FSO at our location in Kosice, Slovakia. To accomplish this we used fog sensor and wrote a simulating program for data processing. The industries as well as universities are already trying to solve the problems when FSO link is not working out because of low visibility. There is already the hybrid equipment on the market which serves as an additional component (an enhancement by using RF (Radio Frequency waves.

Objective: The main objective of the pilot study was to determinate satisfaction of graduates with accredited programs of nursing (prior to the accreditation and after accreditation at two state universities in the eastern region of Slovakia. Methods: The monitored group consisted of total 132 respondents (nursing graduates who completed the 1st degree of nursing study at University of Presov in Presov or University of P. J. Safarik in Kosice in the timeframe 2007-2011. The study was realized during calendar years 2012-2013. One year of nursing clinical practice of graduates was required for this study. Data was collected through a modified questionnaire of feedback used at the University of Presov, Faculty of Health Care within the improvement of curricula program and the whole educational program. Results: Statistically significant differences were observed in area of optional courses of nursing study program (p < 0.05. Compulsory optional courses of nursing program at both universities were more interest and important for clinical practice of graduates after accreditation than before accreditation. Conclusions: The nursing study program meets the educational requirements of European Union. However, study program needs courses, which would be more interesting and effective for clinical practice.

    On Monday steel works U.S. Steel, s.r.o., Kosice (USSK) filed an suit against Slovak Ministry of Environment with the Supreme Court of the Slovak Republic (SR). Together with the mother company United States Steel Corporation they claim that the provisions of contract the company signed with Slovak Republic on purchase of Vychodoslovenske zeleziarne (VSZ) were broken. They officially announced their intention to claim compensation for all 'financial losses related to illegal decrease of carbon dioxide quotas.' The company has also filed a suit with the European Court of Justice against European Commission. The difference between the original quotas granted to the company and the current volumes is 830-thousand tons a year. The market price payable for CO 2 emissions has not been defined yet. 'The higher will be the interest in increased limits the higher will be their price,' admits spokesman of the company, Jan Baca. But the prices could get close to the maximum amount represented by a penalty of 40 EUR for releasing 1 ton of carbon dioxide above the limit. The final allocation grants the steel works a quota 8% lower then the original agreement with SR. The company keeps stressing that since it gained control over the steel works in 2000 it has invested about 180 mil. USD into environmental activities

  19. Loss of energy business

    Russian PM Vladimir Putin, euphoric about the signing of the 25-year contract for the use of Ukrainian seaports by the Russian Navy, announced several new strategic bilateral projects. The new partnership between the two countries might be a disappointment for those who were hoping for new Slovak energy business development in cooperation with Moscow. Representatives of the Russian company TVEL frequently visited the Slovak Ministry of Economy last year, discussing the idea of a nuclear fuel production plant in Slovakia. The factory was supposed to make fuel for the growing number of Russian reactors throughout Europe and utilize the recently discovered uranium deposits near Kosice. However, since Mr. Putin unveiled the idea of creating a Russian-Ukrainian nuclear holding at the site of the Khmelnitskaya Nuclear Power Plant, Slovakia will probably not become the gate to the EU for Russia's atomic business. Owners of the Slovak uranium deposit site are losing business too. And not only does the Slovak-Russian nuclear cooperation seem to be completely lost, but the gas transfer business is unclear too. Last week, the Russian gas company Gazprom showed that its selling prices are a matter of political bargaining rather than fair market value. Similar to low prices for the extremely friendly Belarus, Ukraine earned a $100 discount and in exchange for the Black Sea deal it will be paying only $236 per thousand cubic meters of the commodity. Russia thus gave up roughly $3 billion this year. Slovakia has nothing to offer in exchange for such a deal. Not only price creation but also the construction of gas pipelines through Europe remains a political issue for Russians. With plans to bypass Ukraine and Slovakia, the only safe future for the local transit system can be the result of an idea to pool Gazprom and Ukrainian Naftohaz transit assets together with a stock swap.

    Our investigations were concerned with dynamic changes in total lipids (CL), cholesterol (CHOL) and progesterone (P4) in blood serum of sheep in the period of oestrus synchronization treatment and during mating and gravidity. Our experiment was carried out using 10 animals housed under the conditions of productive rearing. Blood samples were taken from v. jugularis on day of swab application (day 0) and on days 3 and 7 of the action of Agelin vaginal swabs, on day of insemination, and on days 7, 14, 17 and in the 2nd, 3rd and 4th month of gravidity. Blood serum was used to determine total lipids and cholesterol by means of Bio-Lachema tests, and P4 concentrations employing RIA-test-Prog kits (URVJT, Kosice). A statistically significant decrease in concentrations of total lipids (Fig. 1, Tab. I) in sheep blood serum was recorded on day of insemination (P < 0.05) compared to day 0, with the value 1.59 +/- 0.31 g/l of serum, and in the 3rd month of gravidity (P < 0.01), at concentrations 1.36 +/- 0.38 g/l of serum. The determined decrease in their values in the mentioned period can be modulated by the mutually changing ratio of steroid hormones or by inhibition of synthesis of lipoproteins responsible for changes in total plasma lipids. Changes in cholesterol concentrations (Fig. 2, Tab. I) during the introduction of swabs were insignificant and ranged from 1.60 +/- 0.42 to 1.73 +/- 0.33 mmol/l of serum. An insignificant increase in cholesterol concentrations (P < 0.05), with its highest levels 1.98 +/- 0.43 mmol/l of serum, was recorded in the 3rd month of gravidity.(ABSTRACT TRUNCATED AT 250 WORDS)

    Living in Roma settlements is associated with worse health in comparison with the majority population; this might be partially explained by socioeconomic disadvantages as well as cultural differences, including lifestyle. Eating habits represent an important part of lifestyle closely related to primary causes of morbidity and mortality, such as cardiovascular diseases, metabolic diseases or cancers. The eating habits of the population living in Roma settlements in comparison with those of the majority population were explored using the cross-sectional epidemiological HepaMeta study conducted in 2011. A representative sample of Roma (n = 452, mean age = 34.7; 35.2% men) and non-Roma (n = 403, mean age = 33.5; 45.9% men) aged 18-55 years living in the Kosice region were asked about breakfasting and recent consumption of fruits, vegetables, dairy products, meat products, meat, farinaceous dishes, and soft drinks. A logistic regression model was used separately for male and female participants. The population living in Roma settlements reported the recent consumption of fruit, vegetables and dairy products significantly less frequently in comparison with the majority population. Moreover, Roma females, in comparison with non-Roma females, reported significantly more frequently the consumption of meat and soft drinks. No differences were found between Roma and non-Roma in the consumption of meat products and farinaceous dishes. The population living in Roma settlements reported more frequently unhealthy eating habits in comparison with the majority population; this might contribute to worse health status of this population. The differences might be attributed to cultural differences between ethnic as well as socioeconomic groups, reduced availability of certain food items due to segregation or poverty and lower health literacy.

    Wood is again being used for heating and, thanks to this development, in Filakovo a small town in the southern part of Central Slovakia solid fuel cookers and fireplace production is growing. In less then 15 years an international player has emerged from a bankrupt state owned company. The limited partnership, Thorma Vyroba, is still looking for new markets for its products. Enamel production has a 100-year tradition in Filakovo. In the beginning, the company made kitchenware but later the factory suffered the same fate as its owners and the country. During the First Republic, the company specialised in metal-working and later during the war, military production. After nationalization, the company was in the hands of the state for over 50 years. At the end of the 70's, the product portfolio decreased and the factory specialized in the production of enamelled products. At the beginning of 90's the company lost its traditional markets and that was the end. It was highly indebted and went bankrupt, its 3 600 employees lost their jobs. VSZ Kosice tried to acquire the company for 1 Sk, but without success. Finally a group of 6 companies succeeded. According to one of the current co-owners and production manager of Thorma, Jaroslav Matuz, this was the only way that half a dozen limited liability companies could have acquired premises the state was only willing to sell as a whole. The main production capacities were acquired by four of the former company managers who started new cooker production from nothing with the help of people they knew from the factory. 'We started with two products and 80 people,' recalls J. Matuz. And their starting position on the market was the same - zero. At first a local partner, who was also the majority shareholder, helped in Slovakia, the Czech Republic and in Germany. (author)

    Analysis of the nuclear material of the seized illicit trafficking container was performed in the laboratory LARCHA. The container was professionally taken apart in the hot cell of HUMA-LAB APEKO. The compact core of container with mass of 36.00 kg was separated and analysed in the LARCHA laboratory. The results of alpha spectrometry proved that the core of container was made of depleted uranium. A suspicious container was seized, that was believed to be used for transportation of radioactive and nuclear materials. Container, according to Slovak Law, was transported to a Civil defence and police started with expertise analysis. On the basis of previous results, it was assumed that the core of the container was made of a nuclear material. The container was cut inside a hot cell to separate parts at HUMA-Lab Kosice and individual parts were prepared for analyses. From shape and type of the detained container it was assumed that the core of the container was made of depleted uranium and suspected cut pieces were sent to the accredited laboratory LARCHA Bratislava for isotope analysis. Samples from different parts of the container were analysed by using HPGe gamma. The results of gamma spectrometry proved the presence of Co-60, Cs-137 and U-235 with values 11.8 Bq, 5.6 Bq a 3.8 Bq respectively. On the basis of measured results it was calculated mass content (%) of uranium isotopes in samples. It was concluded that: - container is composed of different parts, which are made from steel, lead and uranium; - the wipe tests proved the presence of radionuclides of Cs-137 and Co-60; - the core of the container is made of depleted uranium; - chosen methods, which were used proved that are suitable for analysis and identification of nuclear materials.

    The paper presents the results od 22-year study of screening and follow-up of haemoglobinopathies in Slovakia, an overview of genetic mutations, the coincidence with hereditary haemochromatosis mutations, and the procedure in genetic councelling. Between 1993-2015, in three centres in Bratislava and in one centre in Kosice, carriers of beta-thalassaemic genes or other haemoglobinopathies were searched for. Diagnosis was performed by haematologists, whereby the family history was evaluated, together with the overall clinical condition, blood count and blood smear, iron and haemolysis parameters, mutations of hereditary haemochromatosis, and haemoglobin electrophoresis testing. In the last years the haemoglobin division also examined by high performance liquid chromatography (HPLC). A clinical suspicion of the heterozygous form of beta-thalassaemia or other haemoglobinopathies was documented in 554 patients. Of them 32 (5.8%) were foreigners. 213 (38.45%) patients were genetically examined. In 190 (33.93%) of them heterozygote beta-thalassaemia was confirmed. The most frequent mutations were IVS 1.110 (33.15%), IVS 2.1 (33.15%), and IVS 1.6 (14.7%). Evidence of haemoglobin S (heterozygote sickle cell anaemia) was also notable in two non-relative children, whose fathers were of African origin, and one patient from Ghana. One female patient was followed up for haemoglobin Santa Ana (non-stabile haemoglobin previously diagnosed as mutation de novo). In our group, we took care of pregnant patients with haemoglobinopathies. The study showed that there is a higher number of heterozygotes for beta-thalassaemia and rarely haemoglobinopathies in Slovakia. Over the past years, we have recorded an increase number of foreigners coming to our country. It is necessary to continue in search of pathological gene carriers to avoid serious forms of haemoglobinopathies. Copyright© by the National Institute of Public Health, Prague 2017

    Full Text Available Abstract Background Lower socioeconomic position is generally associated with higher rates of smoking and alcohol consumption and lower levels of physical activity. Health-related behaviour is usually established during late childhood and adolescence. The aim of this study is to explore changes in health-related behaviour in a cohort of adolescents aged between 15 and 19, overall and by socioeconomic position. Methods The sample consisted of 844 first-year students (42.8% males, baseline in 1998 – mean age 14.9, follow-up in 2002 – mean age 18.8 from 31 secondary schools located in Kosice, Slovakia. This study focuses on changes in adolescents' smoking, alcohol use, experience with marijuana and lack of physical exercise with regard to their socioeconomic position. Four indicators of socioeconomic position were used – adolescents' current education level and employment status, and the highest education level and highest occupational status of their parents. We first made cross tabulations of HRB with these four indicators, using McNemar's test to assess differences. Next, we used logistic regression to assess adjusted associations, using likelihood ratio tests to assess statistical significance. Results Statistically significant increases were found in all health-related behaviours. Among males, the most obvious socioeconomic gradient was found in smoking, both at age 15 and at 19. Variations in socioeconomic differences in health-related behaviour were more apparent among females. Although at age 15, almost no socioeconomic differences in health-related behaviour were found, at age 19 differences were found for almost all socioeconomic indicators. Among males, only traditional socioeconomic gradients were found (the lower the socioeconomic position, the higher the prevalence of potentially harmful health-related behaviour, while among females reverse socioeconomic gradients were also found. Conclusion We confirmed an increase in unhealthy

    In member states of the European Union, portion of buildings in the total consumption of energy represents 40 %, and their share in CO2 emissions represents 35 %. Taking into account the dependence of the European Union on import of energy, this represents a large quantity of energy and CO2 in spite of the fact that effective solutions for the reduction of energy demand of buildings exist. The European Union adopted three main commitments for fulfilment of criteria by year 2020 in the 20-20-20 Directive. Based on this Directive Slovakia declares support for renovating the building stock. The goal of the paper was to prove that renovation of the building stock is environmentally and energy preferably as construction of new buildings. In the paper, the settlement unit with the suburban one were compared. Both territories are dealt with in Kosice city, in Slovakia. The settlement units include apartment dwelling houses, amenities, parking areas and green. Suburban part contains family houses. The decisive factor for the final assessment of the buildings was global indicator. Global indicator of the energy performance is primary energy. The new building must meet minimum requirements for energy performance and it must be classified to energy class A1 since 2016, and to energy class A0 since 2020. The paper analyses the effects of the use of different resources of heat considering the global indicator. Primary energy was calculated and based on comparable unit. The primary energy was accounted for on the built-up area, area corresponding to district city and suburb, number of inhabitants. The study shows that the lowest values of global indicator are achieved by using wood. The highest values of global indicator are achieved by using electricity or district heating as an energy source. The difference between the highest and lowest value is 87 %. Primary energy based on inhabitant is 98 % lower in settlement unit compared to the suburban one.

    In Slovakia a strange approach to the purchase of health care equipment has not been limited to ophthalmology. Suspicious procurements are symptomatic. This applies also to specialisation where the correct spending of money can make the difference between life and death and can greatly effect the quality of life. More than a year ago, the Ministry of Health started the procurement of linear accelerators for oncology units in three hospitals. This plan placed on the market a potential order worth more than 11 million EUR without VAT. Three companies produce this complex equipment. The US company, Varian, the German company, Siemens, and the Swedish company, Elekta. Three suppliers, three hospitals. What a coincidence that each hospital - in Presov, Banska Bystrica and Bratislava - received only one envelope with an offer. Each from a different supplier. If anyone wanted to prove that the suppliers did not agree on a common approach, he would soon get into trouble. Each tender was organized by Pro-Tender, Kosice. The tender for the purchase of linear accelerators observed all the legal regulations. For each hospital there was only one offer and so it won. No-one complained, because each company got an order. Amedis Piestany will deliver a Varian product to Bystrica. In Narodny onkologicky ustav in Bratislava the winner was Transkontakt with Elekta products. And in Presov it was Ad Rem from Dunajska Streda that succeeded. The small company owned by a local vet joined up with Siemens and is now opening the doors of state-owned and regional hospitals to the company. (authors)

    Background Vulvovaginal candidiasis (VVU) is considered as a special risk factor during pregnancy, with important influence on the reproductive function of the patients and on the morbidity in the newborns from mothers with VVC. Maternal VVC is a major risk factor for the development of candida-colonization of the infant, which in turn is the first step towards the development of mucocutaneous or systemic candidiasis and Candida-septicemia in the newborn. In pregnant patients, the possible applicable local and systemic medications are limited, while the therapeutic resistance in chronic recurrent forms of VVC increases, facts that require precision of the diagnosic approach to optimize the therapeutic recommendations in pregnant patients, considered as a high risk group. The aim of this study was to investigate in vitro antifungal susceptibility of Candida yeasts to current antifungal agents in pregnant patients with confirmed VVC before the act of birth. Material and Methods Vaginal secretions of 23 healthy pregnant women with proven Candida vaginitis were taken within 48 hours before birth and the presence of yeasls of Candida was confirmed by culture examination. Between 47-72 hours after birth, samples were taken for Candida colonization of the oralmucosa and feces of their newborns. Samples were plated on Sabouraud agar and cultured in an incubator for 2 to 3 days at a temperature of 25° C. Species identification of the isolated yeasts were performed by commercial API Candida test - API 20C AUX (BioMerieux, Marcy-l'Etoile, France). Part of the isolates was identified by commercial whale AUXACOLOR (BioRad, Mames la Coquette, France). Antifungal sensitivity of isolated strains was examined by applying commercial solicitation ready kit and methods of disc diffusion and E-test, as the aim of the authors was to assess their potential for use in the diagnosis, and the correlation between them. Results Candida albicans was the prevalent etiological agent in pregnant

    Teehan, Sean

    Waste heat recovery from low efficiency industrial processes requires high performance thermoelectric materials to meet challenging requirements. The efficiency such a device is quantified by the dimensionless figure of merit ZT=S2sigmaT/kappa, where S is the Seebeck coefficient, sigma is the electrical conductivity, T is the absolute temperature and kappa is the thermal conductivity. For practical applications these devices are only cost-effective if the ZT is higher than 2. Theoretically it has been proven that by engineering nanostructures with lower dimensionality one can significantly increase ZT. A superlattice, or a system of 2-dimensional multilayer quantum wells has previously shown the potential to be used for thermoelectric structures. However, the use of conventional materials within these structures has only allowed this at low temperatures and has utilized cross-plane transport. This study focuses on both high temperature range operation and the in-plane transport properties of such structures, which benefit from both quantum confinement and an enhancement in density of states near EF. The n-type structures are fabricated by alternately sputtering barrier and well materials of Al-doped ZnO (AZO) and indium co-doped AZO, respectively. Samples investigated consist of 50 periods with targeted layer thicknesses of 10nm, which results in sufficient sampling material as well as quantum well effects. The indium doping level within the quantum well was controlled by varying the target power, and ultimately results in a 3x improvement in power factor (S 2sigma) over the parent bulk materials. The film characterization was determined by X-ray reflectometry, transmission electron microscopy, X-ray diffraction, auger electron spectroscopy, as well as other relevant techniques. In addition, process optimization was performed on material parameters such as layer thickness, interface roughness, and band-gap offset which all play a major role in determining the

    Slovak air protection legislation is fully identical with the relevant EU legislation. The results of air pollution monitoring in Slovakia in 2005 are summarised in the presented report. The territory of Slovakia was partitioned into 8 zones (identical with administrative regions) and 2 agglomerations (the largest cities Bratislava and Kosice). In 2005 there were specified 18 air quality management areas, which totally includes 2 836 km 2 and 1 518 179 inhabitants (28 % of population). National air pollution monitoring network in Slovakia is maintained by the Slovak Hydrometeorological Institute (SHMU). In 2005, it consists from 28 real-time monitoring stations, 7 real-time ground level ozone monitoring stations only and 5 regional background stations. The monitoring network was built in accordance with the rules given in EU directives. The results of measurements in 2005 are summarised in Tab. 3.1-3.4. With respect to limit values the main problem in Slovakia represent high level of PM 10 concentrations. Except one at all on-line monitoring stations the daily limit value was exceeded more frequent than 35 days. However, it should be emphasized that long-range transboundary transport in Slovakia plays very important role resulting in high regional background PM concentrations. The SO 2 limit values were not exceeded at any station. Despite of previous years the SO 2 alert threshold did not occur in 2005 (Tab. 3.3). NO 2 concentrations were below limit values at the whole territory of Slovakia. The highest yearly average 38.0 μg.m -3 was observed at Nitra-Stefanikova traffic station. The CO concentrations were below upper assessment threshold and Pb below lover assessment threshold at all monitoring stations. The annual average concentrations of benzene were slightly over the 5 μg.m -3 (limit value for 2010) at two stations. Ground level ozone data is summarized in Chapter 4. Ozone represents a specific problem in Slovakia. Concentration level is mostly controlled

    In this Annual report of the Slovak Electric, plc (Slovenske elektrarne, a.s.) the results of operation in 2002 for the period from January 1 to January 21 are presented. It is unusual for a year to be considered as a matter of a few days, however, this is the case given the events at Slovak Electric, joint stock company which as of 21. 1. 2002 was dissolved and from which three new joint stock companies were established. Further proof of this is the annual report for 2002, which details the economic performance of the company during these 21 days, and the quantity of electricity and heat it generated and supplied to consumers. I am pleased to be able to state that this period of far-reaching changes during which the division of Slovak Electric, joint stock company into the new Slovak Electric, joint stock company, Slovak Electricity Transmission System, joint stock company and Heat Plant Kosice, joint stock company took place, did not cause any problems for Slovak consumers of electricity and heat. During the mentioned 21 January days of 2002, the sources of Slovak Electric generated 836,751 MWh of electricity, which represents 107 percent of the planned generation. The net profit for this period was 742,920 thousand crowns, the main influence being, of course, its short duration. As our economists have confirmed, the most important fact with a significant impact on net profit can be considered to be the amount of deferred taxes, which totalled 1,026,789 thou. Sk. With respect to the dissolution of the company, the company will apply 50 % tax depreciation from annual depreciation, which will, however, be reflected in the results of the newly established company - SE, a.s., as in the subsequent 344 day period its tax deductible depreciation will fall. It is clear that in the forthcoming period, in addition to this, many financial issues remain to be resolved by the management connected with the new form of the business, price, and management relationships within

Control of diabetes is often unsatisfactory because the patient does not know about the principles of successful insulin therapy (ie, blood glucose self-monitoring, the principles of insulin administration, titration, current dose adjustments, dietary recommendations, and physical activity preventive measures or because these principles are applied incorrectly or insufficiently. Furthermore, the fear of hypoglycemia may lead to maintaining higher than recommended blood glucose levels. Methods/design: This is a noninterventional, international study focusing on a questionnaire survey of diabetes patients (patient-reported outcome treated with insulin for at least 1 year. It is designed so that the data obtained reflect real access of patients to insulin treatment. The primary objective is to show the results of glycemic control of diabetes (HbA1c achieved in diabetes patients treated with at least one dose of insulin. The secondary objective is to monitor the factors potentially affecting these results, which include the frequency and other characteristics of hypoglycemia, the frequency of blood glucose self-monitoring, and the effects produced when the results

    Previous results from studies performed in three European cities suggested a decrease in DNA repair efficiency observed in lymphocytes of subjects occupationally exposed to environmental carcinogenic polycyclic aromatic hydrocarbons (c-PAHs). The aim of this study was to investigate whether a relationship between exposure to environmental c-PAHs and cellular vulnerability to the induction of DNA damage and its repair is confirmed in a pooled group of subjects from Prague, Kosice and Sofia. The investigated pool consisted of 144 subjects occupationally exposed to environmental c-PAHs, who were municipal policemen or bus drivers. A control group of 115 matched individuals consisted of males unexposed at work to c-PAHs. The repair efficacy was evaluated by a comparison of the DNA damage detected by the single cell gel electrophoresis (SCGE) immediately after challenging the cells with X-ray irradiation, with residual damage (RD) being measured after an incubation period of 60 min. A stochastic concept for a mechanism of the interaction between DNA and various genotoxic exposures, was applied to analyze a relationship between exposure and biological effect in the studied sample. The outcome of the study confirms that the exposure to environmental c-PAHs or smoking cigarettes, significantly decreases DNA repair efficiency (repair efficiency in the pooled group of exposed individuals was 61.8 ± 11.8% versus 67.9 ± 9.9 in control, p (Val/Val) enzyme, or slow NAT2 acetylators, who showed a considerably lower DNA repair efficiency (i.e. average repair efficiency in subgroups of fast acetylators was for the control subgroup 68.1% versus 66.5% in exposed subjects, while in the case of subgroups of slow acetylators, for the control group was 68.0% versus significantly less in the exposed subjects, 60.6%, p < 0.05). Smoking habits, or the diet's vitamin content, significantly affected the process. The results obtained confirm a potential value of the method as a biomarker of

    Full Text Available Abstract Background Alcohol use and misuse and their relation to sociodemograhic factors are well studied among university students in Western European countries and the USA, but less is known about students in Eastern Europe. The historical past as communistic countries might have affected the social life among these populations, which is again one of the main factors determining the alcohol consumption among university students. The aim of our study was to assess the association of selected sociodemographic factors with different patterns of alcohol use among university students in Slovakia. Methods A sample of 813 young adults (mean age 21.1 years, 63.8% females; response rate of 71% from four universities in Kosice answered questions about their sociodemographic background and about alcohol use. To obtain a detailed picture of different aspects, alcohol use was measured by four variables: frequency of alcohol use, heavy episodic drinking, frequency of drunkenness and problem drinking. Four separate logistic regression models were used to assess the association between sociodemographic and alcohol-related variables. To assess the potentially different effects in both genders, all two-way interactions with gender were tested. Results While 41% of the students drank alcohol once a week or more often, 77% reported heavy episodic drinking and 49% had been drunk more than once in the last month. Problem drinking existed in 23.3% of the sample. Gender was consistently associated with all four alcohol-related variables, with males being at higher risk. A higher study year was associated only with lower levels of heavy episodic drinking, but displayed no association with the other studied variables. Living with parents during the semester was consistently associated with less frequent heavy episodic drinking, drunkenness episodes, and problem drinking while having an intimate relationship was associated with less problem drinking only.

    Water and sediment samples collected during spring 1996 from 20 sampling sites of the Romanian sector of the Danube river and the Black Sea coast were analyzed by instrumental neutron activation analysis (INAA) and by chemical methods to determine major, minor and trace element contents. The concentrations of 43 elements (Ag, Al, As, Au, Ba, Br, Ca, Ce, Cl, Co, Cr, Cu, Cs, Eu, Fe, Ga, Hf, Hg, K, La, Lu, Mg, Mn, Mo, Na, Nd, Ni, Rb, Sb, Sc, Se, Sm, Sr, Ta, Tb, Ti, Th, U, V, W, Yb, Zr, Zn) were investigated by INAA at WWR-S reactor in Bucharest. Chemical methods were used to determine the content of P 2 O 5 and SiO 2 in sediments. For INAA, the water residues and sediment samples were irradiated at the WWR-S reactor in Bucharest at a neutron fluence rate of 2.3·10 12 cm -2 s -1 . As standards, reference materials IAEA-Soil 7 and WTM (sludge from city water treatment, from the Institute of Radioecology and Applied Nuclear Techniques Kosice, Slovakia) as well as chemical compounds of Al, Ca, Mg, V were used. Mono-standard method was applied in the case of Ti and Sr (Cl and Zn as standards, respectively). By chemical methods, the amount of SiO 2 was determined in sediment samples after the treatment with concentrated HCl and residuum dis-aggregation by fusion (melting with a mixture of Na 2 CO 3 and K 2 CO 3 ). Phosphorus was determined by spectrophotometry with ammonium molybdate and by reduction with ascorbic acid. It can be seen that, both for water and sediment samples, the highest contents of Al, Co, Cs, Fe, Rb, and Sb were found at the sites located upstream the Portile de Fier dam: at Turnu Severin (for water) and Orsova (for sediments). Ag, Au, Ni, Yb, Zr were determined only in some of the water samples at the following concentration levels: ng L -1 (Au, Lu), tens of ng L -1 (Ag, Tb, Yb), hundreds of ng L -1 (Ag), μg L -1 (Ni, Zr), tens of μg L -1 (Ni, Ti). From a comparison with results of our previous studies for the Danube bottom sediments, no significant

However, there are only few works describing daytime experiments or synchronization of animals to the external environmental periodicity. The aim of the study is to describe the circadian rhythm of the electrical stability of the heart under hyperventilatory conditions. Methods: Circadian rhythms of the electrical stability of the heart, measured by ventricular arrhythmia threshold ([VAT] measurement in 3 hour intervals, were followed during normal artificial ventilation (40 breaths/minute, tidal volume = 1 mL/100 g; n = 17 and hyperventilation (80 breaths/minute, tidal volume = 2 mL/100 g; n = 7 in pentobarbital (40 mg/kg administered intraperitoneally anesthetized female Wistar rats, after 4 week adaptation on the light/dark regime of 12 hour light/12 hour dark (40%–60% humidity, room temperature of 24°C in cages, two animals/cage with access to food and water ad libitum, with the dark period from 18.00h to 06.00h for 4 weeks. Results: The 24 hour course of the VAT showed the highest susceptibility of the rat ventricular myocardium to arrhythmias between 12.00h and 15.00h, and highest resistance between 19.20h and 00.28h (acrophase −338° in time at 22.53h with confidence intervals −2,880° to −70°, under normoxic conditions. Mesor was 2.59 ± 0.53 mA and amplitude 0.33 ± 0.11 mA. Hyperventilation increased the VAT at each interval of the measurement, but did not change the character of its circadian rhythm.
