Full Text Available This paper deals with the Czechoslovak communist regime in the period 1985 – 1989. The author analyses character of the communist regime, the special features of the liberation and the fall of this regime. He applies theories of Carl J. Friedrich, Zbigniew Brzezinski, Juan J. Linz, Alfred Stepan, Gordon Skilling, Wolfgang Merkel, Herbert Kitschelt, Adam Przeworski and others. In author’s opinion the Czechoslovak communist regime was a ”melting” post-totalitarianism. It is a special category of post-totalitarian regimes that gives together natures of Linz´s and Stepan´s ”frozen” and ”mature” post-totalitarianism and Skilling´s ”consultative” and ”quasi-pluralistic” post-totalitarianism. The specific character of the Czechoslovak communist regime resulted in the ”negotiated collapse”.

Full Text Available This structure organizes in three levals the various functions related to the academy such as classrooms, conference rooms, chapel, gymnasiums, music rooms and a cafeteria. In the distribution, a concentrated-circulation scheme in a broad central vestibule, near the accesses and the stair wells, has been adopted for the purpose of avoiding extensive corridors and hallways and achieving comfortable and well-defined circulation appropriate for an intensive operation. Natural lighting is one of the needs given prime attention by the solution adopted and is obtained by means of large side Windows on the perimeter and slanted roofs and skylights in the interior. The combination of the inclined glass panels with the dynamic movement of the roofs gives the whole a distinct architectural personality which can be appreciated both from the inside and in the exterior volumes.Esta construcción organiza en tres niveles las diversas funciones relacionadas con la Academia, tales como: salas de clase y de conferencias, capilla, gimnasios, salas de música y una cafetería. En la distribución se ha adoptado un esquema de circulación concentrada en un amplio vestíbulo central, próximo a los accesos y a las cajas de escalera, con el propósito de evitar extensos corredores y pasillos, y procurar una circulación cómoda y bien definida, apta para un funcionamiento intensivo. La iluminación natural es una de las necesidades que la solución adoptada atiende en primer término, obteniéndose mediante ventanales laterales en el perímetro y cubiertas inclinadas y lucernarios en el interior. La combinación de los paneles inclinados de cristal con el movimiento dinámico de las cubiertas otorga al conjunto una marcada personalidad arquitectónica, apreciable tanto desde el interior como en los volúmenes exteriores.

Teoreticheskie aspekty prigranichnogo jekonomicheskogo sotrudnichestva na osnove integracionnyh processov

Directory of Open Access Journals (Sweden)

Bilchak V.

2014-08-01

Full Text Available In this article the author analyses theoretical aspects of border economy in the conditions of modern processes of integration. The author describes the existing schools and concepts of integration stressing the role of government regulation relating to the deformations in the development of the world economic mechanism. Modern studies focus on the evolution of integration processes, which has largely affected the key elements of the world economic mechanism from classical political economy, monopoly regulation. This resulted in monopolistic competition, imperfect competition, and oligopoly – largely, through all fields and poles of economic growth to certain elements of government regulation and social reproduction on the international scale. The author examines the key elements and stages of economic integration. These stages assume a number of consecutive forms: free trade zone, customs union, common market, complete economic integration, and economic union. The article shows that the transition occurs from the lowest to the highest stages — from the processes of integration involving, firstly, trade market and then capital and labour markets to the integration of social sphere. The theoretical aspects of all these transformations can be easily traced in the case of EU integration processes.

Editorial, Equipo

1977-07-01

Full Text Available The mission of this huge under-river sewer is to carry the waste water from the left bank of the Danube to the other side of the river where a large sewage treatment plant is being constructed. In order to carry out its 375 m in length and 2.4 m inside diameter, where several drain pipes and ducts for remote heating and supply of electric power are housed, a system of pressure propulsion has been sed. This system is based on a series of hydraulic presses, which gradually insert into the ground the prefabricated reinforced concrete tubular elements, 3 m in length, which form the sewer. The work on the aforementioned sewer is completed with a pumping well located on the left bank and originated by the difference in level between the connections of the respective sewers on each side of the river — as well as a collection well, situated on the right bank, which links up with the main sewer of the treatment plant. Both wells are built with reinforced concrete.La misión de este gran colector subfluvial es la de conducir las aguas residuales procedentes de la orilla izquierda del Danubio al otro lado del río, en donde se está construyendo una gran planta depuradora. Para la realización de sus 373 m de longitud y 2,40 m de diámetro interior, donde se albergan diversas tuberías de desagüe y conductos para calefacción a distancia y suministro de energía eléctrica, se ha empleado un sistema de propulsión a presión. Dicho sistema se basa en una serie de prensas hidráulicas, que van introduciendo en el terreno los elementos tubulares prefabricados de hormigón armado, de 3 m de longitud, que constituyen el colector. Los trabajos del citado colector se completan con un pozo de bombeo —situado en la orilla izquierda y originada por la diferencia de nivel existente entre las acometidas de los respectivos colectores de ambos lados del río— y otro de recogida, emplazado en la orilla derecha, que enlaza con el colector principal de la central depuradora. Ambos pozos se realizaron a base de una construcción de hormigón armado.

Full Text Available ENGLISH: The paper presents two examples of the dealing with religion and religious diversity in kindergarten. The results – which come from a kindergarten of the city of Vienna and a Caritas Kindergarten in Linz – make it clear that, from a peace-political and inclusive-pedagogical point of view supplements to the educational concepts for the elementary level are necessary. Only a pedagogy which fully perceives the family culture of the children, and therefore also addresses their religious background, may be satisfactory for the individual child in a religiously pluralistic society. DEUTSCH: Der Beitrag präsentiert zwei Beispiele für den Umgang mit Religion und religiöser Vielfalt im Kindergarten. Die Ergebnisse – die aus einem städtischen Kindergarten in Wien und einem Pfarr-Caritas Kindergarten in Linz stammen – machen deutlich, dass aus friedenspolitischer und inklusionspädagogischer Sicht Ergänzungen in den Bildungskonzepten für den Elementarbereich notwendig sind. Nur eine Pädagogik, welche die Familienkultur der Kinder umfassend wahrnimmt, und somit auch ihre religiöse Herkunft aufgreift, kann dem einzelnen Kind in einer religiös pluralen Gesellschaft gerecht werden.

Experimental investigation of asphalt mixture containing Linz-Donawitz steel slag

Directory of Open Access Journals (Sweden)

Jens Groenniger

2017-08-01

Full Text Available Standard asphalt mixtures for road infrastructures consist of natural aggregate and bitumen. A number of research efforts have successfully investigated the possibility of replacing the conventional aggregate skeleton with industrial by-products such as slag originating from steel production process. However, little is known on the effect of steel slag on the mixtures performance properties such as resistance to low-temperature cracking and to permanent deformation, stiffness and fatigue. This paper presents a comprehensive investigation on the fundamental performance properties of different types of asphalt mixtures prepared with 100% LD slag aggregate and a conventional asphalt mixture containing natural Gabbro aggregate. Sophisticated testing methods were used to evaluate the key performance parameters for the set of asphalt mixtures investigated. In this study, low temperature cracking was addressed through thermal stress restrained specimen tests. Penetration tests and cyclic compression tests were used to evaluate the response of asphalt binder and asphalt mixture to permanent deformation due repeated loading, respectively. The cyclic indirect tensile test was selected for investigating both stiffness properties and fatigue resistance. For this purpose the complex stiffness modulus was measured to quantify material stiffness under different temperature and loading conditions providing information on the visco-elasto-plastic material behavior. Fatigue tests were used to determine the progressive and localized material damage caused by cyclic loading. The experimental results indicate that asphalt mixtures prepared with LD slag are suitable for asphalt pavement construction and that in most cases they perform better than conventional asphalt mixtures prepared with Gabbro aggregate.

Ispas, N.; Nastasoiu, M.

2017-10-01

Reducing the effects of traffic accidents over the occupants is a major objective of collision attempts. Impacts between the car and the pole are very dangerous for the physical integrity of the car’s occupants. To minimalize the effects of such events on the passengers of a vehicle, a whole series of efforts by both designers and experienced engineers led to increasingly the vehicles safety. The main aim of these paper is to quantify the influences over the car passengers of loads involved by car against pole collisions using the same car model at different speeds. Also, this kind on occupant influences were study using a small car model. Other goal of the paper was the study of the cars stiffness in frontal collision against the pole. The paper’s experimental results were obtained by support of DSD, Dr. Steffan Datentechnik GmbH - Linz, Austria. The described tests were performed in full test facility of DSD Linz, in “Easter 2016 PC-Crash Seminar”. Cars accelerations, velocities, rotations angles after pole impact were registered and discussed. The novelty of the paper consists in studies referred for the same car model involved in car against pole collisions at different impact speeds. Paper’s conclusions can be future used for car safety improvement.

Effects of feedback on residential electricity demand—Findings from a field trial in Austria

International Nuclear Information System (INIS)

Schleich, Joachim; Klobasa, Marian; Gölz, Sebastian; Brunner, Marc

2013-01-01

This paper analyzes the effects of providing feedback on electricity consumption in a field trial involving more than 1500 households in Linz, Austria. About half of these households received feedback together with information about electricity-saving measures (pilot group), while the remaining households served as a control group. Participation in the pilot group was random, but households were able to choose between two types of feedback: access to a web portal or written feedback by post. Results from cross section OLS regression suggest that feedback provided to the pilot group corresponds with electricity savings of around 4.5% for the average household. Our results from quantile regressions imply that for households in the 30th to the 70th percentile of electricity consumption, feedback on electricity consumption is statistically significant and effects are highest in absolute terms and as a share of electricity consumption. For percentiles below or above this range, feedback appears to have no effect. Finally, controlling for a potential endogeneity bias induced by non random participation in the feedback type groups, we find no difference in the effects of feedback provided via the web portal and by post. - Highlights: • We estimate the effects of feedback on household electricity use in a field trial in Linz, Austria. • Providing feedback on electricity use corresponds with average savings of around 4.5%. • Effects of feedback are most pronounced in the 30th to the 70th percentile. • Feedback provided via a web portal and by post appears equally effective

At the Krankenhaus der Barmherzigen Schwestern in Linz 153 patients with cancer of the uterine cervix in the stages 1 to 3 have been treated from August 1980 to December 1985. In 146 patients (95.4 %) complete remission could be achieved. The 5-years overall survival probability (Kaplan-Mayer) in the stages 1 to 3 is 79.3 %, 62.6 % and 40.8 % respectively. The 5-year recurrence free survival rate is 91.5 %, 59.6 % and 52.9 % respectively. These results are equivalent to the data achieved by treatments with Radium application. Using the high-dose-rate afterloading method the complication rate is lower. (Authors)

Erosion wear response of epoxy composites filled with steel industry slag and sludge particles: A comparative study

Science.gov (United States)

Purohit, Abhilash; Satapathy, Alok

2018-03-01

In the field of composite research, use of industrial wastes such as slag and sludge particles as filler in wear resistant polymer composites has not been very common. Owing to the very high cost of conventional filler materials in polymer composites, exploring the possibility of using low cost minerals and industrial wastes for this purpose has become the need of the hour. In this context this work explores the possibility of such polymer composites filled with low cost industrial wastes and presents a comparison of mechanical characteristics among three types of epoxy based composites filled with Linz - Donawitz sludge (LD sludge), blast furnace slag (BF slag) and Linz - Donawitz slag (LD slag) respectively. A comparative study in regard to their solid particle erosion wear characteristics under similar test conditions is also included. Composites with different weight proportions (0, 5, 10, 15 and 20 wt. %) of LD sludge are fabricated by solution casting technique. Mechanical properties such as micro- hardness, tensile strength and flexural strength of three types of composites have been evaluated as per ASTM test standards and solid particle erosion wear test is performed following a design of experiment approach based on Taguchi’s orthogonal array. Five control factors (impact velocity, erodent size, filler content, impingement angle and erodent temperature) each at five levels are considered to conduct erosion wear tests. The test results for epoxy-LD sludge composites are compared with those of epoxy-BF slag and epoxy-LD slag composites reported by previous investigators. The comparison reveals that epoxy filled with LD sludge exhibits superior mechanical and erosion wear characteristics among the three types of composites considered in this study. This work also opens up a new avenue for value added utilization of an abundant industrial waste in the making of epoxy based functional composites.

Johannes Kepler and his contribution to Applied Mathematics

Science.gov (United States)

Pichler, Franz

The worldwide renown of Johannes Kepler is based above all on his contribution to astronomy. The 3 Kepler's Laws relating to the planets are well known and will ensure that his name is remembered by future generations. Besides his astronomical work, Kepler also made important contributions in the fields of theology, physics, phylosophy and mathematics. The actual paper discusses the advances by Kepler in the application of mathematics to the solution of "real life problems". The author made a concise account of some of the disciples by Kepler: Klug, Wieleitner, Caspar, Hammer, paying particular attention to works published by Kepler while he was living in Linz (1612-1628). The Kepler's contribution to applied mathematics is an example supremely worthy of emulation, the author concludes.

The measurement system of Li-8100 carbon flux and the modified assimilation chamber were used to study the photosynthetic characteristics of cotton (Gossypium hirsutum L.) canopy in the oasis edge region in middle reach of Heihe River Basin, mid Hexi Corridor of Gansu. At the experimental site, soil respiration and evaporation rates were significantly higher in late June than in early August, and the diurnal variation of canopy photosynthetic rate showed single-peak type. The photosynthetic rate was significantly higher (P transpiration rate also presented single-peak type, with the daily average value in late June and early August being (3.10 +/- 0.34) mmol H2O x m(-2) x s(-1) and (1.60 +/- 0.26) mmol H2O x m(-2) x s(-1), respectively, and differed significantly (P efficiency in late June and early August was (15.67 +/- 1.77) mmol CO2 x mol(-1) H2O and (23.08 +/- 5.54) mmol CO2 x mol(-1) H2O, respectively, but the difference was not significant (P > 0.05). Both in late June and in early August, the canopy photosynthetic rate was positively correlated with air temperature, PAR, and soil moisture content, suggesting that there was no midday depression of photosynthesis in the two periods. In August, the canopy photosynthetic rate and transpiration rate decreased significantly, because of the lower soil moisture content and leaf senescence, but the canopy water use efficiency had no significant decrease.

the expected value when implementing different metropolitan governance model. If the comparison showed the non-optimality of the implemented model for some index of the economic growth, then the values of the economic growth in the metropolitan area and the national average were compared. As a result, a recommendationwas given for the metropolitan area on the degree of need for the management reform and an optimal metropolitan governance model was selected.Results. Based on the revealed regularities, we have created a methodical approach to choose the optimal model of metropolitan governance according to the population size. It can be used as a tool to justify metropolitan governance reform. The advantage of the approach is the use of real quantitative data that reduces the degree of subjectivity in decision-making Conclusion. The methodical approach is tested on the example of eightmetropolitan areas (Lublin, Palermo, Krakow, Paris, Stuttgart, Madrid, Geneva, and Linz. It was revealed that there is no metropolitan governance model, which is always more efficient for all objects. As the result of the analysis for Geneva, the degree of need for management reforms was described as “high” with a recommendation for a transition to a decentralized metropolitan governance model. For Linz, Stuttgart and Madrid, the degree of need for reform is characterized as “low” with a recommendation for a transition to decentralization (Stuttgart and centralization (Linz and Madrid. The rest of the metropolitan areas of the sample do not need reforms.

This article describes the current state of research concerning the fate of mentally ill people in the psychiatric hospital of Klagenfurt am Wörthersee during the era of National Socialism (NS). Sterilization based on the "Erbgesundheitsgesetz" (genetic health law) deportation to the Castle of Hartheim near Linz, transport to Klagenfurt and killing in the departments of the hospital are documented. This knowledge is to be given to the relatives. Encouraged by diverse public work activities relatives of victims of NS euthanasia sought contact with the department to discover the fate of relatives. Touching meetings with the relatives took place. Since January 2011 the contacting relatives, their motives and the meetings have been protocolled and in this study an attempt is made to give an initial characterization of these people. This approach of a reconstructive biographical work together with relatives of the victims is presented as a proactive duty of psychiatric institutions.

In 2000, CERN hosted Signatures of the Invisible – one of the landmark initiatives in arts and science. In 2012, CERN is now initiating its own science/arts programme Collide@CERN in different arts disciplines. The first of these is in digital arts, and the international competition to find the winning artist is called the Prix Ars Electronica Collide@CERN. It was announced September 2011 at CERN’s first collaboration with an international arts festival – Ars Electronica in Linz. The competition attracted over 395 entries from 40 countries around the world. The winning artist, Julius Von Bismarck, will begin his two month residency here at CERN next month. Ariane Koek who leads on this initiative, discusses the residency programme, as well as the background about Art@CERN. History has shown that particle physics and the arts are great inspiration partners. The publication of the paper by Max Planck which gave birth to quantum mechanics as well as those by Einstein, heavily influenced some of the grea...

Leptospira inadai is classified as a species of the Leptospira intermediate group that has been poorly studied due to its apparent insignificance to human and animal health. Nevertheless, over the last two decades the species has been described in human cases in India and in carrier animals in Ecuador. Here, we present the first identification and genomic characterisation of L. inadai serogroup Lyme isolated from captured rodent in Brazil. Even though the M34/99 strain was not pathogenic for hamsters, it was able to establish renal colonisation. The M34/99 strain presented high similarity with L. inadai serogroup Lyme human reference indicating that animal strain could also infect humans, although it does not represent high risk of severe disease. An extrachromosomal sequence was also identified in M34/99 strain and presented high identity with previously described L. inadai phage LinZ_10, suggesting that phage-like extrachromosomal sequence may be another feature of this understudied species.

The second part of the artistic programme Collide@CERN was officially launched at the beginning of November. The initiative, a dance and performance award, is the result of a partnership between CERN, the City of Geneva and the Canton of Geneva.   From left to right: Sami Kanaan, Rolf Heuer, and Charles Beer. The project Collide@CERN was launched in September in the framework of CERN's new cultural policy (announced in an article published in Bulletin No. 50-51/2010). The project, whose main objective is to achieve a symbiosis between the imagination of artists and the creativity of scientists, features an artist-in-residence scheme that will run for three years. The Organization has concluded two cultural partnerships for the purpose: one with Ars Electronica Linz, an Austrian organisation specialising in the digital arts, which will sponsor a digital arts prize (see article published in Bulletin No. 37-38 earlier this year), and the other with the City and the Canton of Geneva, wh...

Monitoring of carbamazepine concentrations in wastewater and groundwater to quantify sewer leakage.

Monitoring of carbamazepine concentrations in wastewater and groundwater enables us to identify and quantify sewer exfiltration. The antiepileptic drug carbamazepine is hardly removed in wastewater treatment plants and not or just slightly attenuated during bank infiltration and subsoil flow. Concentrations in wastewater are generally 1000 times higher than the limit of quantification. In contrast to . many other wastewater tracers carbamazepine is discharged to the environment only via domestic wastewater. The results from this study carried out in Linz, Austria indicate an average exfiltration rate of 1%, expressed as percentage of the dry weather flow that is lost to the groundwater on the city-wide scale. This rate is lower than sewage losses reported in most other studies which attempted to quantify exfiltration on the basis of groundwater pollution. However, it was also possible to identify one area with significantly higher sewage losses. This method seems to be very suitable for the verification of leakage models used to assess sewer exfiltration on a regional scale.

This paper discusses how energy consumption and energy loss can be reduced in reheating furnaces of hot rolling mills by new lightweight refractory materials and a new modular lining concept for the skid pipe insulation using pre-fabricated shells. The target is to optimise the hot rolling process from an energy point of view, and to reduce the operational cost of the furnaces. The new lightweight pre-fabricated shells based on the microporous castable and a thermotechnical optimised sandwich design can significantly reduce the heat losses compared to dense castable. Industrial application of the new system in a 110 t/h pusher type furnace at voestalpine Grobblech GmbH in Linz, Austria, resulted in reduction of heat loss about 30 %. The annualised energy saving gives a cost reduction of more than Euro 200,000 a year. Costs for the complete new lining about Euro 170,000 result in a payback period of less than one year. (orig.)

Caspar, Max

1993-01-01

A towering figure in intellectual history and one of the fathers of modern astronomy, the great mathematician Johannes Kepler (1571–1630) is best known for his discovery of the three laws of planetary motion, which paved the way for a dynamic explanation of the heavenly phenomena. At a time when the Ptolemaic view still prevailed in official circles, Kepler undertook to prove the truth of the Copernican world view and through exceptional perseverance and force of intellect achieved that goal. His epochal intellectual feats are completely and thoroughly described in this splendid work, considered the definitive biography of Kepler. Drawing on a wealth of primary sources, the author presents a fascinating and erudite picture of Kepler's scientific accomplishments, his public life (work with Tycho Brahe, the Danish astronomer; mathematical appointments at Graz, Prague, and Linz; pioneering work with calculus and optics, and more) and his personal life: childhood and youth, financial situation, his mother's tri...

Progress in developing microprocessor computer hardware is based on progress and improvement in systems engineering, circuit engineering and manufacturing process methods of design and development of large-scale integrated circuits (BIS). Development of these methods with widespread use of computer-aided design (CAD) systems has allowed developing 4- and 8-bit microprocessor families (MPK) of LSI circuits based on integrated injection logic (I/sup 2/L), characterized by relatively high speed and low dissipated power. The emergence of LSI and VLSI microprocessor circuits required computer system developers to make changes to theory and practice of computer system design. Progress in technology upset the established relation between hardware and software component development costs in systems being designed. A characteristic feature of using LSI circuits is also the necessity of building devices from standard modules with large functional complexity. The existing directions of forming compositions of LSI microprocessor families allow the system developer to choose a particular methodology of design, proceeding from the efficiency function and field of application of the system being designed. The efficiency of using microprocessor families is largely governed by the user's understanding in depth of the structure of LSI microprocessor family circuits and the features of using them to implement a broad class of computer devices and modules being developed. This book is devoted to solving this problem.

Theoretical And Experimental Investigations On The Plasma Of A CO2 High Power Laser

Science.gov (United States)

Abel, W.; Wallter, B.

1984-03-01

The CO2 high power laser is increasingly used in material processing. This application of the laser has to meet some requirements: at one hand the laser is a tool free of wastage, but at the other hand is to guarantee that the properties of that tool are constant in time. Therefore power, geometry and mode of the beam have to be stable over long intervalls, even if the laser is used in rough industrial environment. Otherwise laser material processing would not be competitive. The beam quality is affected by all components of the laser - by the CO2 plasma and its IR - amplification, by the resonator which at last generates the beam by optical feedback, and also by the electric power supply whose effects on the plasma may be measured at the laser beam. A transversal flow laser has been developed at the Technical University of Vienna in cooperation with VOest-Alpine AG, Linz (Austria). This laser produces 1 kW of beam power with unfolded resonator. It was subject to investigations presented in this paper.

U.S. males and pornography, 1973-2010: consumption, predictors, correlates.

Science.gov (United States)

Wright, Paul J

2013-01-01

Although both storied and extensive, social scientific research on the effects of pornography consumption on males has primarily focused on testing the feminist contention that pornography contributes to sexual aggression against females. Other parties have expressed concern about males' use of pornography, however. "Moralists" (Linz & Malamuth, 1993 ) have argued that pornography promotes a permissive approach to sexual relations. Public health researchers have hypothesized that pornography encourages epidemiologically risky sexual behavior. This study used cross-sectional General Social Survey data gathered between 1973 and 2010 to assess these claims for empirical support. In line with moralists' contentions, pornography consumption was associated with having more positive attitudes toward teenage sex, adult premarital sex, and extramarital sex. Pornography consumption was also positively related to actually engaging in extramarital sex. In line with public health researchers' concerns, pornography consumption was associated with having more sexual partners and engaging in paid sex behavior. Additional longitudinal and experimental research is needed to determine the directionality of these associations and to rule out possible third-variable confounds, such as erotophilia or hypersexuality. Regarding consumption, the percentage of adult U.S. males who consume pornography appears to have increased only slightly over time.

United States women and pornography through four decades: exposure, attitudes, behaviors, individual differences.

2013-10-01

Responding to a call for research on pornography and women's sexuality made by Weinberg, Williams, Kleiner, and Irizarry (2010), this study assessed pornography consumption, predictors, and correlates using nationally representative data gathered from U.S. women between 1973 and 2010 (N = 18,225). Women who were younger, less religious, and non-White were more likely to consume pornography. Women who consumed pornography had more positive attitudes toward extramarital sex, adult premarital sex, and teenage sex. Women who consumed pornography also had more sexual partners in the prior year, prior 5 years, and were more likely to have engaged in extramarital sex and paid sex. Consistent with Wright's (2011a) acquisition, activation, application model of mass media sexual socialization and the theorizing of Linz and Malamuth (1993), liberal-conservative ideology moderated the association between pornography exposure and sexual behavior. Specifically, the positive association between pornography exposure and women's recent sexual behavior was strongest for the most liberal women and weakest for the most conservative women. Cultural commentators and some academics argue that technological advances have resulted in a steady increase in the percentage of individuals who consume pornography. Little support was found for this assertion among U.S. women.

Reminding the life and legacy of the Austrian Scientist who discovered the famous 'Doppler Effect'. C.A. Doppler was born the 29th of November 1803 in Salzburg. After studies in Linz and Vienna, he graduated in mathematics, became assistant at the University and later worked as a professor in Prague. Back to Vienna, he was appointed as professor at the Polytechnic School and --in 1850--as first director of the new Institute of Physics. C.A. Doppler did publish on magnetism, electricity, optics, and astronomy. He remains in the history of science due to the discovery presented (May 25, 1842) at the Royal Bohemian Society of Science entitled "On the colored light of the double stars and certain other stars of the heavens"; the paper described (applied to light) the shift of frequency which bears nowadays his name. The theory was later experimentally proven and--extended for any electromagnetic and acoustic waves--got myriads if applications in astronomy, physics, aviation, meteorology, and health science. Satomura in Japan (1955) published it's first ultrasound vascular application--with successive achievements in the next decades. Doppler ultrasonagraphy became the main noninvasive instrument for functional assesment of heart and vessels.

DomFLIP++ is the knowledge engineering module of the *FLIP++ project. *FLIP++ is a tool for optimizing multiple criteria problems. It uses fuzzy constraints to model optimizing criteria and applies algorithms such as Tabu search or genetic algorithms to the problems. DomFLIP++ is a C++ library. It allows the definition of new optimization problems. It helps a domain engineer to design the structure of a new problem. However, there is a domain independent interface to other *FLIP++ modules such as OptiFLIP++, DynaFLIP++, and InterFLIP++. After each iteration in the optimization process, the considered instantiations of the problem are evaluated. Each evaluation produces a list of violated constraints. For each constraint in further iterations of the optimization. A domain can be fine-tuned through modifications of constraints, through editing their repair lists, and through change in the optimizing parameters. A well-tuned domain can be successfully applied for optimization. Object-oriented design and implementation makes this module easy to modify and to reuse. Definition of new domains, system extensions with new optimizing algorithms, and definition of specific domain-dependent repair steps can be done efficiently. DomFLIP++ is tested on real-world example, namely scheduling the steel plant LD3 in Linz, Austria

Nitrate in shallow groundwater in typical agricultural and forest ecosystems in China, 2004-2010.

The nitrate-nitrogen (NO3(-)-N) concentrations from shallow groundwater wells situated in 29 of the Chinese Ecosystem Research Network field stations, representing typical agro- and forest ecosystems, were assessed using monitoring data collected between 2004 and 2010. Results from this assessment permit a national scale assessment of nitrate concentrations in shallow groundwater, and allow linkages between nitrate concentrations in groundwater and broad land use categories to be made. Results indicated that most of the NO3(-)-N concentrations in groundwater from the agro- and forest ecosystems were below the Class 3 drinking water standard stated in the Chinese National Standard: Quality Standard for Ground Water (ecosystems (4.1 +/- 0.33 mg/L) than in forest ecosystems (0.5 +/- 0.04 mg/L). NO3(-)-N concentrations were relatively higher (> 10 mg N /L) in 10 of the 43 wells sampled in the agricultural ecosystems. These elevated concentrations occurred mainly in the Ansai, Yucheng, Linze, Fukang, Akesu, and Cele field sites, which were located in arid and semi-arid areas where irrigation rates are high. We suggest that improvements in N fertilizer application and irrigation management practices in the arid and semi-arid agricultural ecosystems of China are the key to managing groundwater nitrate concentrations.

Bone scanning in patients with low back pain following minimal trauma

Full text: Low back pain following minimal trauma may be caused by insufficiency fracture of the sacrum, which is often radiographically occult. Bone scintigraphy is a method of reference for the diagnosis; the results have been analyzed retrospectively. Bone scintigraphy was done on 228 patients treated by the departments of orthopedics at the General Hospital Linz. Predominantly after (minor) trauma, they suffered from lower back pain and their conventional radiographic findings were negative. During a 24 month period, a sacral insufficiency fracture was diagnosed in 68 patients (29,8 %). H-shaped hyperfixation of the tracer - described as typical - was present in only 12 % of the gases. Tracer accumulation was found as follows: located uni/bilateral in the sacral wings (39 % / 9 %), horizontal (31 %) and half H-shaped (9 %). In the majority of the gases bone scan detected farther fractures with main localization in the pubic bones, in the spine and the ribs. The insufficiency fracture of the sacrum as cause of lower back pain is not uncommon, especially in postmenopausal women with risk factors. Bone scintigraphy is not only an adequate procedure for the detection of often radiographically occult sacral fractures, but also an easy method to reveal the often concomitand fractures. (author)

FY 1999 report on basic survey for joint implementations, etc. Basic feasibility study on energy conservation at Novolipetsk Steelworks

The survey involves COP (Conference of the Parties) joint implementations, etc., at the Russian Novolipetsk Steelworks (NLMK) who produces crude steel at 9.9-million tons/year. A large waste heat recovery system is introduced into the NLMK for reduction in natural gas consumption and in electric power purchase. The waste heat recovery facilities involve a sintering cooler/heater, TRT (top-pressure recovery turbine), and LD (Linz-Donawitz) converter gas recovery. Energy will be saved at 1730 Tcal/year, and greenhouse gas (CO2) will be reduced at 408,000 tons/year. A total of 20.9 times 1-billion yen needs to be invested. Since energy is priced low in Russia, the investment will result in but a little economic effect. In the Russian industrial circle, however, there is a move to raise the energy price by stages to secure corporation operating funds and refurbish obsolete facilities. Accordingly, probabilities are quite high that the project proposed here will be implemented if low-interest financing is available. Talks will continue between the two parties over yen credit availability, etc. It is indispensable to construct a framework which will enable implementations in compliance with COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change).

Downscaling of Short-Term Precipitation from Regional Climate Models for Sustainable Urban Planning

Directory of Open Access Journals (Sweden)

Holger Hoppe

2012-05-01

Full Text Available A framework for downscaling precipitation from RCM projections to the high resolutions in time and space required in the urban hydrological climate change impact assessment is outlined and demonstrated. The basic approach is that of Delta Change, developed for both continuous and event-based applications. In both cases, Delta Change Factors (DCFs are calculated which represent the expected future change of some key precipitation statistics. In the continuous case, short-term precipitation from climate projections are analysed in order to estimate DCFs associated with different percentiles in the frequency distribution of non-zero intensities. The DCFs may then be applied to an observed time series, producing a realisation of a future time series. The event-based case involves downscaling of Intensity-Duration-Frequency (IDF curves based on extreme value analysis of annual maxima using the Gumbel distribution. The resulting DCFs are expressed as a function of duration and frequency (i.e., return period and may be used to estimate future design storms. The applications are demonstrated in case studies focusing on the expected changes in short-term precipitation statistics until 2100 in the cities of Linz (Austria and Wuppertal (Germany. The downscaling framework is implemented in the climate service developed within the EU-project SUDPLAN.

Mineral carbonation can stabilize industrial residues and, in the steel industry, may contribute to simultaneously valorize CO2 emissions and slag. We hypothesized that, by restricting the leaching of metals of toxicological concern such as Cr and V, carbonation can suppress the toxicity of these materials. The cytotoxic activity (WST1 assay) of slag dusts collected from a stainless and a Linz-Donawitz (LD) steel plant, before and after carbonation, was examined in J774 macrophages. The release of Cr, V, Fe, Mn and Ni was measured after incubation in artificial lung fluids mimicking the extracellular and phagolysosomal milieu to which particles are confronted after inhalation. LD slag had the higher Fe, Mn and V content, and was more cytotoxic than stainless steel slag. The cytotoxic activity of LD but not of stainless dusts was reduced after carbonation. The cytotoxic activity of the dusts toward J774 macrophages necessitated a direct contact with the cells and was reduced in the presence of inhibitors of phagocytosis (cytochalasin D) or phagolysosome acidification (bafilomycin), pointing to a key role of metallic constituents released in phagolysosomes. This in vitro study supports a limited reduction of the cytotoxic activity of LD, but not of stainless, steel dusts upon carbonation. Copyright © 2015 Elsevier Ltd. All rights reserved.

20 years ago, Michael Schnitzler founded the NGO "Rainforest of the Austrians" to help save one of the most diverse rainforests in Central America, the Esquinas rainforest on the Pacific coast of SW Costa Rica, from being destroyed through logging. In this abstract we present an interdisciplinary upper Austrian school project aiming at building positive awareness in pupils towards rainforest conservation by fund-raising to help purchase endangered forest areas. The acquired rainforest was donated to the Costa Rican government and became part of the National Park "Piedras Blancas". In the following, we present a chronology of events and actions of the school project. We started our rainforest project by face-to-face encounters, letting involved persons speak directly to the pupils. Dr. Huber, coordinator of the tropical rainforest station La Gamba in Costa Rica (www.lagamba.at), together with Dr. Weissenhofer, presented an introductory slide show about the "Rainforest of the Austrians". With rainforest images and sounds in their mind the pupils wrote "trips of a lifetime" stories, thus creating idyllic images of rainforest habitats. Following up on that, we visited the exhibition "Heliconia and Hummingbirds" at the Biology Center in Linz. Reports about the slide show and the exhibition followed. Tropical sites were compared by producing climate graphs of La Gamba, Costa Rica, and Manaus in Brazil. The global distribution and the decrease of rainforests were also analyzed. In biology lessons the symbiosis between plants and animals of the rainforest were worked out by searching the Internet. Flyers with profiles of rainforest animals were produced. We also discussed the ecotourism project "RICANCIE" in Ecuador using fact sheets. "RICANCIE" is a Spanish acronym standing for "Indigenous Community Network of the Upper Napo for Intercultural Exchange and Ecotourism". It was founded in 1993 aiming to improve the quality of life for some 200 indigenous Kichwa families

1993-01-01

East Germany fibers producer Thuringische Faser AG Schwarza (TFS; Rudolstadt) is entering the polyethylene terephthalate (PET) business. The company, owned by India's Dalmia Group (New Delhi), is building an 80,000-m.t./year PET granulate plant, one of the largest in Europe, for completion at the end of 1995. The product will be used to make PET bottles and film for food packaging. TFS will need to buy 70,000 m.t./year of purified terephthalic acid and 27,000 m.t./year of ethylene glycol to feed the new plant. When acquiring TFS, Dalmia's chairman, Sanjay Dalmia, pledged to invest DM150 million ($95.4 million) in the Germany firm and keep 1,200 of the 3,000 workers. John Brown Deutsche Engineering (Essen) has been awarded a contract covering engineering, know-how, and turnkey supply of the complete plant, and will share of the complete plant, and will share the work with Austrian associate, Voest John Brown Industrieanlagenbau (Linz). The company, which completed against Zimmer (Frankfurt), will use its own technology. TFS, with 1992 sales of DM120 million, has capacities to produce 20,000 m.t/year of viscose staple fiber, 18,000 m.t./year of nylon-6 filament yarn, and 6,300 m.t./year of textile-grade polyester granulate, which will be converted to produce bottle-grade PET

Over the past decades, with increasing steel manufacturing, the huge amount of by-products (slags) generated need to be reused in an efficient way not only to reduce landfill slag sites but also for sustainable and eco-friendly agriculture. Our preliminary laboratory study revealed that compared to blast furnace slag, electric arc furnace slag and ladle furnace slag, the Linz-Donawitz converter (LD) slag markedly decreased CH 4 production rate and increased microbial activity. In the greenhouse experiment, the LD slag amendment (2.0 Mg ha -1 ) significantly (p < 0.05) increased grain yield by 10.3-15.2%, reduced CH 4 emissions by 17.8-24.0%, and decreased inorganic As concentrations in grain by 18.3-19.6%, compared to the unamended control. The increase in yield is attributed to the increased photosynthetic rates and increased availability of nutrients to the rice plant. Whereas, the decrease in CH 4 emissions could be due to the higher Fe availability in the slag amended soil, which acted as an alternate electron acceptor, thereby, suppressed CH 4 emissions. The more Fe-plaque formation which could adsorb more As and the competitive inhibition of As uptake with higher availability of Si could be the reason for the decrease in As uptake by rice cultivated with LD slag amendment.

The Lush Prize supports animal-free testing by awarding monetary prizes totalling £250,000 to the most effective projects and individuals who have been working toward the goal of replacing animals in product or ingredient safety testing. Prizes are awarded for developments in five strategic areas: Science; Lobbying; Training; Public Awareness; and Young Researchers. In the event of a major breakthrough leading to the replacement of animal tests in the area of 21st Century Toxicology, a Black Box Prize (equivalent to the entire annual fund of £250,000) is awarded. The Science Prize is awarded to the researchers whose work the judging panel believe has made the most significant contribution to the replacement of animal testing in the preceding year. This Background Paper outlines the research projects that were shortlisted and presented to the judging panel as potential candidates for the 2016 Lush Science Prize. This process involved reviewing recent work of the relevant scientific institutions and projects in this area, such as the OECD, CAAT, The Hamner Institutes, ECVAM, UK NC3Rs, and the US Tox21 Programme. Recent developments in toxicity testing research were also identified by searching for relevant published papers in the literature, and analysing abstracts from conferences focusing on animal replacement in toxicity testing that had been held in the preceding 12 months - for example the EUSAAT-Linz, Society of Toxicology, and SEURAT-1 conferences. 2017 FRAME.

After an overview about the basics of electricity the thesis covers the history of the electricity market in Upper Austria from the very beginning including parallels to national activities and trends in this field. The historical part is therefore divided into three chapters: the development of the electricity supply in Austria, Upper Austria and Linz. In the following chapter the thesis discusses the legal basis for the structure of Austria' electricity market as well as the latest laws dealing with the liberalization of Austria' electricity market as well as the European legislative conditions regulating the liberalization of the European electricity market. The thesis furthermore deals with the effects on customers as well as on the suppliers that are yet affected by the ongoing liberalization in the various customer segments. It also covers the expected affects on Austria' private customers that will occur by the complete deregulation that starts in October 2001. The thesis covers also the actual strategic plans of Austria' public owned suppliers in the effort to strengthen their market positions. In contrary to the deregulated telecom market the electricity markets won' grow. Therefore, competition on the electricity market will get much harder. Suppliers will strain for cooperation and mergers in order to face this competition, which is underlined in this part of the thesis. The fourth chapter covers the ecological items of electricity production and consumption. It therefore deals with renewable and nuclear energy sources and their contributions to a sustainable economy. (author)

Nowcasting of rainfall and of combined sewage flow in urban drainage systems.

Nowcasting of rainfall may be used additionally to online rain measurements to optimize the operation of urban drainage systems. Uncertainties quoted for the rain volume are in the range of 5% to 10% mean square error (MSE), where for rain intensities 45% to 75% MSE are noted. For larger forecast periods up to 3 hours, the uncertainties will increase up to some hundred percents. Combined with the growing number of real time control concepts in sewer systems, rainfall forecast is used more and more in urban drainage systems. Therefore it is of interest how the uncertainties influence the final evaluation of a defined objective function. Uncertainty levels associated with the forecast itself are not necessarily transferable to resulting uncertainties in the catchment's flow dynamics. The aim of this paper is to analyse forecasts of rainfall and specific sewer output variables. For this study the combined sewer system of the city of Linz in the northern part of Austria located on the Danube has been selected. The city itself represents a total area of 96 km2 with 39 municipalities connected. It was found that the available weather radar data leads to large deviations in the forecast for precipitation at forecast horizons larger than 90 minutes. The same is true for sewer variables such a CSO overflow for small sub-catchments. Although the results improve for larger spatial scales, acceptable levels at forecast horizons larger than 90 minutes are not reached.

Full Text Available We analyzed the corpus of three geoscientific journals to investigate if there are enough locational references in research articles to apply a geographical search method, such as the example of New Zealand. Based on all available abstracts and all freely available papers of the “New Zealand Journal of Geology and Geophysics”, the “New Zealand Journal of Marine and Freshwater Research”, and the “Journal of Hydrology, New Zealand”, we searched title, abstracts, and full texts for place name occurrences that match records from the official Land Information New Zealand (LINZ gazetteer. We generated ISO standard compliant metadata records for each article including the spatial references and made them available in a public catalogue service. This catalogue can be queried for articles based on authors, titles, keywords, topics, and spatial reference. We visualize the results in a map to show which area the research articles are about, and how much and how densely geographic space is described through these geoscientific research articles by mapping mentioned place names by their geographic locations. We outlined the methodology and technical framework for the geo-referencing of the journal articles and the platform design for this knowledge inventory. The results indicate that the use of well-crafted abstracts for journal articles with carefully chosen place names of relevance for the article provides a guideline for geographically referencing unstructured information like journal articles and reports in order to make such resources discoverable through geographical queries. Lastly, this approach can actively support integrated holistic assessment of water resources and support decision making.

The nitrate-N (NO3(-) -N) concentrations of 38 shallow groundwater wells from 31 of the typical terrestrial ecosystems on Chinese Ecosystem Research Network (CERN) were assessed using the monitoring data from 2004 to 2009. The results showed that the average values of NO3(-) -N concentrations were significantly higher in the agricultural (4.85 mg x L(-1) +/- 0.42 mg x L(-1)), desert (oasis) (3.72 mg x L(-1) +/- 0.42 mg x L(-1)) and urban ecosystems (3.77 mg x L(-1) 0.51 mg x L(-1)) than in the grass (1.59 mg x L(-1) +/- 0.35 mg L(-1)) and forest ecosystems (0.39 mg x L(-1) +/- 0.03 mg x L(-1)). Nitrate was the major form of nitrogen, with between 56% to 88% of nitrogen in the nitrate-N form in the shallow groundwater of desert (oasis), urban and agricultural ecosystems. Nitrate-N concentrations for some agricultural ecosystems (Ansai, Yanting, Yucheng) and desert (oasis) ecosystems (Cele, Linze, Akesu) analysis exceeded the 10 mg x L(-1) World Health Organization drinking water standards between 14.3% and 84.6%. Significant seasonality was found in Ansai, Fengqiu, Yanting agricultural ecosystems and the Beijing urban ecosystem using the relatively high frequency monitoring data, with the higher nitrate concentrations usually found during summer and winter months. The monitoring results indicated that the shallow groundwater of agricultural ecosystems was contaminated by agricultural management practices, i.e. fertilization, while the shallow groundwater of forest ecosystems was under natural condition with no contamination from human activities.

Following the 2010 conference held at ETH Zurich, the 13th renowned International Mechatronics Forum Conference--Mechatronics 2012--took place from 17-19 September 2012. Held in Austria for the first time, it was jointly organized by the Johannes Kepler University and the Austrian Center for Competence in Mechatronics (ACCM). In accordance with the Local and International Organizing Committee, we opened new avenues to make this conference more attractive, particularly to industry. Mini-symposia were set up devoted to specific topics. This proved successful in attracting certain scientific communities and groups and gave the conference a broader scope and a more colourful appearance. Another successful attempt was to involve industry more strongly than in previous conferences. The conference's character was influenced by the approach and the specific mechatronic problems of the Linz area in industry, teaching and research. This concept of showcasing the local situation in mechatronics in these areas could be valuable for the future conferences; the international mechatronics community could get an overview about the different interpretations of mechatronics and could form informed opinions about different approaches. Around 150 lecturers from 23 countries around the world covered a broad spectrum of approaches to mechatronic problem solutions, of new technologies, scientific and engineering methods and methodologies. Authors of conference papers in the area of sensors and measurement technology were invited to submit extended papers for publication in this special feature in Measurement Science and Technology , which were all fully peer-reviewed. The topics of the papers that are now collected in this special feature illustrate this variety, from the application of measurement systems to microsystems and algorithms. We are grateful to the editors of Measurement Science and Technology for the opportunity to provide a glimpse of the results presented at the conference

Annual report on the ambient air quality measurement in Austria 2004

2006-01-01

A summary of the ambient air quality situation (measurements) conducted according to the Air Quality Act and the Ozone Act in Austria during 2004 is presented. The situation was assessed mainly in relation to Austrian limit and target values of sulfur dioxide, nitrogen oxides, particulate matter (this is measured using two different indicators: total suspended particulates (TSP) and PM10), carbon monoxide, benzene and lead. The PM10 limit value - 35 days with average concentrations above 50 μg/m 3 - was exceeded at 27 sites. The highest exceedances were measured at traffic related sites in large cities, in particular the city of Graz, in Vienna, at industrial sites (e.g. Linz). Main sources for primary particulate matter are road traffic, domestic heating (in particular wood burning), industrial emissions, construction activities and off-road sources. For nitrogen dioxide, the short term limit value was exceeded at few traffic related sites, mainly - but not only - in larger towns. The limit value for the protection of vegetation of 30 μg/m 3 NO x was exceeded at one site in Tyrol (Kramsach). Limit values for sulfur dioxide were exceeded at three sites. Neither the limit values for carbon monoxide, lead and benzene nor the alert thresholds for nitrogen dioxide or sulfur dioxide were exceeded in this year. Deposition of total particulates limit value was exceeded at a few sites, lead and cadmium in two industrial sites. Low ozone levels were measured at most monitoring sites, the information threshold of 180 μg/m 3 ozone as one hour mean was exceeded at 21 sites on all together 9 days and the alert threshold of 240 μg/m 3 as one hour mean was not exceeded. 45 figs., 57 tabs.

Full Text Available On April 29, 2015 Reinhard Folk - member of the Editorial Board of "Condensed Matter Physics", renowned expert in the fields of condensed matter physics, phase transitions and critical phenomena - celebrated his 70th birthday. Reinhard Folk was born in Neuendettelsau, Germany. He studied at the University of Vienna, where in 1973 he defended his doctoral thesis "Hydrodynamic Equations of Dielectric Crystals" (under supervision of Franz Schwabl. In the same year he started working at the Institute for Theoretical Physics, Johannes Kepler University in Linz, at first as assistant, later as an associate professor, then as extraordinary professor, and finally as Director of the research group "Phase Transitions and Critical Phenomena". His research interests cover various fields of condensed matter physics. In particular, he obtained important results in the theory of ferroelectrics, quantum liquids, critical phenomena in magnets and random systems, spin liquids, superconductors, and neural networks. Reinhard Folk and his collaborators performed a series of studies that became the basis for understanding and quantitative description of phenomena occurring in many systems. Included amongst these are the description of the thermodynamic properties of matter in the vicinity of Lifshitz points, the description of critical dynamics in systems with different types of conservation laws, the analysis of effective (non-asymptotic critical behaviour, and generalized hydrodynamics of many-particle systems. Computing algorithms, resummation methods of asymptotic perturbation series proposed by Reinhard Folk and his collaborators, cover a wide range of applications. In 1982 (together with Volker Dohm he was awarded the Walter Schottky Prize of the German Physical Society for his studies of the critical dynamics of helium-4 . Those of us who were fortunate to know Reinhard Folk closer, are aware of his interests in the history of culture and the history of

Nitraria sibirica usually exists in a form of nebkhas, and has strong ecological adaptability. The plant species has distinctive function for wind prevention and sand fixation, and resistance drought and salt. However, the water condition is still a limiting factor for the plant survival and development. In order to understand the water use strategy of the plant in different desert habitats, we selected the N. sibirica growing in sandy desert habitat and gravel desert habitat to study the seaso-nal variation of plant water sources and response to precipitation at the edge of the oasis of Linze in the Hexi Corridor. We measured the oxygen stable isotope of the plant stem water and the different potential water sources (precipitation, soil water and ground water), and used the IsoSource model to calculate the proportion of water sources from the potential water. The results showed that there were significant seasonal variation characteristics of δ 18 O value and water source of stem water for the plant in the two habitats. In the sandy habitat, the plant used more ground water in the less precipitation seasons including spring and fall, and more than 50% of the water sources absorbed from ground water. However, under the condition of gravel habitat, the plant could not achieve the ground water level depth of 11.5 m, and its water source was controlled by precipitation, which had large seasonal variability. The water sources of N. sibirica had significant responses to the change of precipitation in the two desert habitats. Following the rapid decrease of soil water content after the precipitation events, the plant in the sandy habitat turned to use the abundant ground water as the main sources of water, while the plant in the gravel habitat only used the less water from precipita-tion infiltration to the deep soil. Therefore, different water use strategies of the plant in the two habitats were the main reason for the difference in growth characteristics, and it had a

LiDAR Mapping of Earthquake Uplifted Paleo-shorelines, Southern Wairarapa Coast, North Island, New Zealand

The Hikurangi subduction margin along the east coast of the North Island, New Zealand accommodates oblique convergence of the Pacific Plate westward beneath the Australian plate at 45 mm/yr. Pronounced forearc uplift occurs at the southern end of the margin along the Wairarapa coast, onshore of the subducting Hikurangi plateau. Along a narrow coastal lowland, a series of uplifted Holocene marine terraces and beach ridges preserve a geologic record of prehistoric coseismic uplift events. In January 2017, we participated in the Research Experience for Undergraduates (REU) program of the NSF SHIRE Project (Subduction at Hikurangi Integrated Research Experiment). We visited multiple coastal sites for reconnaissance fieldwork to select locations for future in-depth study. For the coastline between Flat Point and Te Kaukau Point, we used airborne LiDAR data provided by Land Information New Zealand (LINZ) to create ArcGIS digital terrain models for mapping and correlating uplifted paleo-shorelines. Terrace elevations derived from the LiDAR data were calibrated through the use of Real Time Kinematic (RTK) GPS surveying at one field site (Glenburn Station). Prior field mapping and radiocarbon dating results (Berryman et al., 2001; Litchfield and Clark, 2015) were used to guide our LiDAR mapping efforts. The resultant maps show between four and seven uplifted terraces and associated beach ridges along this coastal segment. At some sites, terrace mapping and lateral correlation are impeded by discontinuous exposures and the presence of landslide debris, alluvial fan deposits, and sand dunes. Tectonic uplift along the southern Hikurangi margin is generated by a complex interaction between deep megathrust slip and shallow upper-plate faulting. Each uplifted Holocene paleo-shoreline is interpreted to represent a single coseismic uplift event. Continued mapping, surveying, and age dating may help differentiate between very large margin-wide megathrust earthquakes (M8.0-9.0+) and

Dual-energy X-ray absorptiometry was performed to analyze the bone mineral density, and histomorphometric analysis was performed to measure the parameters related to bone metabolism. Calcein labeling was performed to detect bone formation. The uteruses from the mice were weighed, and the histomorphometry was analyzed. Drug-derived serum was prepared to assess the 17-β-estradiol concentration via enzyme immunoassay.Results: BSNXD administration ameliorated the osteoporotic phenotype of OVX mice, as evidenced by an increase in the bone mineral density and bone volume; these effects could not be abolished by the administration of the aromatase inhibitor letrozole. Moreover, BSNXD had no effect on the serum estrogen concentration or uterus.Conclusion: These results suggest that BSNXD has ameliorating effects on bone loss due to estrogen deprivation without affecting the peripheral blood estrogen concentration or the uterus in OVX mice.

Perioperative mortality, prolonged postoperative recovery after the Norwood procedure, and mortality between stage I and stage II might be related to shunt physiology. A right ventricular to pulmonary artery conduit offers a banded physiology in contrast to a Blalock-Taussig shunt. The purpose of this study was to assess the hemodynamic differences and their consequences in the postoperative course between Norwood patients with a Blalock-Taussig shunt and those with a right ventricular to pulmonary artery conduit. From October 1999 until May 2002, 32 unselected consecutive patients underwent a Norwood procedure at the General Hospital Linz. The first 18 patients received a Blalock-Taussig shunt. In the remaining 14 patients we performed a right ventricular to pulmonary artery conduit. Both groups were compared. The diastolic blood pressure was significantly higher in the right ventricular to pulmonary artery conduit group (P <.001). Despite a higher FIO(2), PO(2) levels tended to be lower in the first 5 postoperative days. At the age of 3 months, catheterization laboratory data showed a lower Qp/Qs ratio in the same group (0.86 [0.78; 1] versus 1.55 [1.15; 1.6]; P =.005) and a higher dp/dt (955 [773; 1110] vs 776 [615; 907]; P =.018). (Descriptive data reflect medians and quartiles [in brackets].) Hospital survival was 72% in the Blalock-Taussig shunt group versus 93% in the right ventricular to pulmonary artery conduit group. Mortality between stage I and stage II was 23% in the Blalock-Taussig shunt group versus 0% in the right ventricular to pulmonary artery conduit group. A higher diastolic blood pressure and a lower Qp/Qs ratio were associated with a more stable and efficient circulation in patients with a right ventricular to pulmonary artery conduit. More intensive ventilatory support was necessary during the first postoperative days. We did not note any adverse effects of the ventriculotomy on ventricular performance.

Heavy steel casting components for power plants 'mega-components' made of high Cr-steels

Energy Technology Data Exchange (ETDEWEB)

Hanus, Reinhold [voestalpine Giesserei Linz GmbH, Linz (Austria)

2010-07-01

Steel castings of creep resistant steels play a key role in fossil fuel fired power plants for highly loaded components in the high and intermediate pressure section of the turbines. Inner and outer casings, valve casings, inlet connections and elbows are examples of such critical components. The most important characteristic in a power plant is the efficiency, which mainly drives the CO2-emission. As a consequence of steadily improving power plant efficiencies and ever stricter emission standards, steam parameters become more critical and the creep resistance of the cast materials must also be constantly improved. The foundries voestalpine Giesserei Linz and voestalpine Giesserei Traisen participated in the development of the new 9-10% Cr-steels for application up to 625 C/650 C and in the THERMIE project where Ni-base alloys for 700 C-power plants were developed. Beside the material development in the European research projects the commercial production had to be established for industrial processes and the newly developed materials have to be transferred from research into the commercial production of heavy cast components. After selecting the most promising alloy from the laboratory melts, welding tests were performed - mostly with matching electrodes also produced within COST/THERMIE. Base material and welds were investigated in respect of microstructure, creep resistance, mechanical properties and weldability. Heat treatment investigations were also necessary for optimization of the mechanical properties. Based on the results of these studies, pilot components and plates for testing welding processes were cast in order to verify the castability and weldability of larger parts and to make any necessary adjustments to chemical composition, heat treatment or welding parameters. Parallel to the ongoing creep tests within COST/THERMIE-program, the newly developed steel grades were introduced into the commercial production of large components. This involved finding

Purpose/Objective: The purpose of this paper is to present our 15 years experience in the primary treatment of cervical cancer with a combination of external beam irradiation and high dose rate brachytherapy. Survival data will be presented and the safe use of intrauterine HDR applications will be demonstrated. Material and Methods: From August 1980 to December 1990, 303 patients with cancer of the uterine cervix underwent primary irradiation in a combination of external beam and HDR intracavitary treatment at the Department of Radiation Oncology at the Sisters of Mercy Hospital in Linz, Austria. All patients were classified according to the FIGO rules: Stage I 54 patients, stage II 171, stage III 75 and stage IV 3 patients. 8 patients were lost to follow up. The mean follow up time of survivors is 110 months. Results: A complete remission could be achieved in 282 patients (93%); persistent tumour was found in 21 patients at the first follow up check 3 to 5 months after completion of irradiation. The actuarial overall survival probability for all patients at 5 and 10 years is 62 % and 49 % respectively, the disease specific survival probability is 68 % and 64 %. The local control rate at 5 and 10 years is 73 % and 72 % respectively. According to stage, disease specific survival lies at 90 % for stage I, 69 % for stage II, and 49 % for stage III and IV at 5 years, and at 10 years 87 %, 66 % and 41 % respectively. The actuarial local control probability for stages I, II, and III/IV is 90 %, 74 %, and 60 % respectively at 5 years, and 88 %, 74 %, and 57 % at 10 years (Kaplan-Meier calculations). From all 303 patients 34 suffered from 40 severe and moderate side effects (glossary of Chassagne and Sismondi). The rate for grade II complications is 10 % and for grade III 3 %. Conclusion: Intrauterine HDR brachycurietherapy in addition to external beam irradiation for primary treatment of invasive carcinoma of the uterine cervix provides the same treatment results as LDR

Full Text Available Pavao Ritter Vitezović was born in Senj on January 12, 1652 and died in Vienna on January 21, 1713. He attended elementary school in Senj and continued his education at a Jesuit high school in Zagreb, where his professor was Juraj Habdelić. After finishing the sixth grade in rhetoric, he quit school and went to Rome, where he met Johannes Lucius (Ivan Lučić. He was taught by cartographer Georg Matheus Vischer in Vienna. Vitezović spent the following two years in Bogenšperk (Wagensberg, Vagensperg, where Johann Weikhard Valvasor taught him surveying and copper-engraving. He prepared most templates for Croatian city views for Valvasor and engraved them in copper plates. He returned to Senj in 1679. As a city emissary, he travelled to the Viennese Parliament, where he advocated for Senj getting a royal charter and rights it had had for a long time. He participated in wars against Turks and became an officer for Nikola Erdödy. While he was staying as an emissary of Senj in Linz in 1684, he produced Odiljenje sigetsko and changed his German last name Ritter to Croatian Vitezović. He used to go outdoors and sketch cities and towers which he subsequently engraved in copper plates. This is how his copper-engravings were made which were incorporated in the album of Valvasor’s Topographia Ducatus Carnioliae modernae (Topography of Duchy of Carniola, as well as in Die Ehre des Herzogthums Crain (Glory of Duchy of Carniola in 1689. He participated in wars for liberation of Lika and Krbava and became the vice-prefect of Lika in 1691. He took over the Land Printing Office (Zemaljska tiskara at the session of the Croatian Parliament in Varaždin in 1694.

She complained of a cough with intermittent hemoptysis and pain in the thoracic spine from which she had been suffering the past 9 weeks. A plain chest X-ray showed a dense infiltrate on the right side and multiple smaller shadows in both lungs. Laboratory testing revealed anemia, leukocytosis, and an increase of C-reactive protein. All tests for tuberculosis were negative.A bronchoscopy was performed and biopsies were taken from the right upper and middle lobe. The histopathological examination found cells of an adenocarcinoma. A magnetic resonance imaging (MRI) revealed a large tumor and surrounding atelectasis were seen in the right upper and middle lobe, as well as multiple intrapulmonary metastases in both lungs. In addition, not only metastases in the thoracic spine (level Th2/3) but also at other osseous locations and multiple cerebral metastases were detected. The patient received one cycle of chemotherapy consisting of docetaxel and carboplatin (AUC5) in the 27th week of gestation. Additional radiotherapy was applied to the involved thoracic spine. Due to positive epidermal growth factor receptor mutation, therapy with gefitinib 250 mg/day was started 2 days after a Caesarean section (preceded by treatment for fetal lung maturation). A healthy girl was delivered in the 30th week of pregnancy. Staging with computed tomography (CT) after delivery revealed an unstable fracture of Th2 with compression of the spinal cord. Neurosurgery was performed, consisting of a ventral corporectomy of Th1-2 followed by an anterior and posterior osteosynthesis for stabilization. The patient was discharged without neurological deficits within 1 week. Subsequent treatment with gefitinib improved the performance status of the patient, and CT scans of the chest and an MRI of the brain showed the size of

On behalf of the Ministry of Environment the Austrian Academy of Science published guideline values for nitrogen dioxide in 1988. The scientific database concentrated on short-term effects of NO{sub 2} at that time. After checking the current literature it was clear that new data especially for long-term effects of NO{sub 2} were available which should lead to a limitation of an annual average. Two Austrian studies on children from Linz (capital of Upper Austria) showed that high long-term concentrations of NO{sub 2} were negatively associated with the flow parameters of terminal airways in spirometry (MEF{sub 25} and MEF{sub 50}) on a significant level. In addition the children showed an improvement in growth-dependent increase of lung function parameters when long-term NO{sub 2}-concentrations in the ambient air could be decreased by more than 40 {mu}g/m{sup 3}. The most pronounced benefit could be seen when the ambient level of NO{sub 2} decreased during periods of accelerated growth. Based on these and other results summarized in this review, the Austrian Academy of Science recommended an annual average of 30 {mu}g/m{sup 3} for NO{sub 2} in the ambient air not to be exceeded for health protection.

Introduction: The purpose of this paper is to present our 15 years experience in the primary treatment of cervical cancer with a combination of external beam irradiation and high dose rate brachytherapy. Survival data will be presented and the safe use of intrauterine HDR applications will be demonstrated. Material and Methods: From August 1980 to December 1990, 303 patients with cancer of the uterine cervix underwent primary irradiation in a combination of external beam and HDR intracavitary treatment at the Department of Radiation Oncology at the Sisters of Mercy Hospital in Linz, Austria. All patients were classified according to the FIGO rules: Stage I 54 patients, stage II 171, stage III 75 and stage IV 3 patients. 8 patients were lost to follow up. The mean follow up time of survivors is 110 months. Results and Discussion: A complete remission could be achieved in 282 patients, which is 93%; persistent tumour was found in 21 patients at the first follow up check 3 to 5 months after completion of irradiation. The actuarial overall survival probability for all patients at 5 and 10 years is 62 % and 42 % respectively, the disease specific survival probability is 68 % and 64 %. The local control rate at 5 and 10 years is 73 % and 72 % respectively. According to stage, disease specific survival lies at 90 % for stage I, 69 % for stage II, and 48 % for stage III and IV at 5 years, and at 10 years 87 %, 66 % and 41 % respectively. The actuarial local control probability for stages I, II, and III/IV is 90 %, 74 %, and 60 % respectively at 5 yr, and 88 %, 74 %, and 56 % at 10 yr. (Kaplan-Meier calculations). From all 303 patients 34 suffered from 40 severe and moderate side effects (glossary of Chassagne and Sismondi). The rate for grade II complications is 10 % and for grade III 3 %. Conclusion: Intrauterine HDR brachycurietherapy in addition to external beam irradiation for primary treatment of invasive carcinoma of the uterine cervix provides the same treatment

An enzyme immunoassay was conducted to measure the 17-β-estradiol (E2 concentration in the drug-derived serum. Bone marrow-derived monocyte/macrophage precursor cells were treated with drug-derived serum, and tartrate-resistance acid phosphatase staining was conducted to observe osteoclastogenesis. A bone resorption assay was performed to analyze the effect on osteoclastic resorptive function. Real-time PCR, flow cytometry, Western blotting, transfection, and luciferase assays were conducted to explore the related mechanism.Results: E2 was not elevated in BSNXD-derived serum. BSNXD-derived serum suppressed receptor activation of nuclear factor κB ligand (RANKL-activated osteoclastogenesis in a dose-dependent manner; this effect could be reversed by estrogen receptor α antagonist methyl-piperidino-pyrazole.

Full Text Available En los regímenes presidenciales de América Latina la vicepresidencia ha sido poco estudiada, a diferencia de los Estados Unidos. Apenas recibió algunos comentarios de autores, como Juan Linz, dudando de su eficacia y señalando algunos de los problemas que rodean su figura, como los criterios de nominación de los candidatos y los conflictos con los presidentes. Pero, prácticamente, la vicepresidencia no se tuvo en cuenta en el debate crítico en relación con el presidencialismo y el parlamentarismo, a pesar de ser el segundo puesto en importancia en el régimen presidencial. Vuelta la democracia en la región, la vicepresidencia ha generado numerosos problemas políticos, sin embargo no existe prácticamente un debate académico sobre ella. Tensiones y graves conflictos entre el presidente y el vicepresidente, hasta vicepresidentes convertidos en opositores son algunos de los problemas observados. Por otra parte, algunos vicepresidentes han ocupado, con distinta suerte, el lugar del presidente ya sea tanto por su fallecimiento como por crisis políticas que culminaron con la salida del mandatario.. En los Estados Unidos, históricamente, existía la imagen devaluada de la vicepresidencia y problemas similares a los observados en América Latina. Pero en el país del norte la vicepresidencia ha sido estudiada desde hace tiempo y la institución ha evolucionado a través de prácticas paraconstitucionales. Ahora la vicepresidencia es una pieza importante del sistema institucional y se encuentra ubicada en la órbita del Ejecutivo. Ha ganado tareas, nuevas funciones e influencia, más allá de la persistencia de las imágenes que poco la favorecen. Debido a esta evolución paraconstitucional cabe esperar de un vicepresidente su participación en el gabinete, su «lobbying» en el Senado, la representación del presidente en el exterior, el papel de consejero presidencial y el desarrollo de tareas importantes que pueda encomendarle el

vulnerability were developed. A comparison with existing data (River Basin Management Plan and Groundwater Chemistry Regulation) shows a good agreement between the elaborated maps and observations for the present state. The Overall Vulnerability is very low and low for most parts of Austria, especially in the forested alpine region. Bigger cities like Vienna, Graz and Linz show medium vulnerabilities, due to the high water demand and low ecosystem services. Only in the north-eastern and south-eastern part of the country some water supply associations with high and very high overall vulnerability exist. Groundwater recharge is quite small in these regions and the water quality is limited due to intense agriculture and possible threats through landfills. The developed framework allows an evaluation of water quantity and quality vulnerabilities for large scales for the present and the future. Including ecosystem services and gross value added an overall vulnerability can be determined.

el orden de magnitud del coeficiente varia en un intervalo de 10{sup 5}. Los autores explican los datos obtenidos sobre la base de la ionizacion del acido complejo HMX{sub 4} en estos disolventes, cuyas constantes dielectricas son relativamente elevadas. Empleando un metodo ideado por Poskanzer, han calculado la constante de ionizacion del electrolito soporte, HCl o HBr, en la fase no acuosa a partir de las variaciones que el coeficiente de extraccion experimenta en funcion de las concentraciones del metal. Las variaciones del coeficiente de extraccion con la concentracion de HX han servido para calcular las constantes de estabilidad de las especies complejas MX{sub 3} y MX{sub 4}{sup -}. Como se trata de reacciones en fase acuosa, las constantes son independientes del disolvente organico que se emplee. Para el sistema In (III)-HCl los autores obtuvieron resultados perfectamente concordantes tanto al emplear eter bis (2-cloroetilico) como nitrobenceno. Los autores no consiguieron evaluar las constantes de los complejos de cloruro y bromuro de galio porque dichos compuestos solo se forman en un intervalo de concentraciones de acido muy estrecho. Los valores del cociente (GaCl{sub 4}{sup -})/{Sigma} Ga (III) en funcion de la concentracion de HCl, calculados a partir de los datos de extraccion, concuerdan con los datos que Kraus y Nelson obtuvieron por mediciones del intercambio ionico.

The method is based on the principle recently described by Failla and his associates: Two plane electrodes of the same material are mounted parallel to, and close beside, each other in a vacuum container and the source which is to be measured is laid on one of them. The back-scattering on this electrode is offset by the reflections on the other electrode. A magnetic or electrical field makes it possible to eliminate the effect of low-energy secondary electrons. In the case of magnetic deflection, the apparatus includes an extrapolation chamber and, in the case of electrical deflection, a chamber with a very fine grille. In the case of Sr{sup 90}-Y{sup 90} and P{sup 32} the results obtained tally very well with the measurements made with the 4 {pi} counter (better than {+-} 2%) In the case of S{sup 35} the results are seen to be affected by the atomic number of the substance of which the electrode whereon the source is placed consists; this must therefore be chosen with care. The theories on back-scattering provide an explanation of these results. (author) [French] Le principe de la methode est celui decrit recemment par Failla et ses collaborateurs: Deux electrodes planes paralleles, de meme substance et tres voisines, sont disposees dans une enceinte videe. Sur une des electrodes est deposee la source a mesurer. La retrodiffusion sur l'electrode porte-source est compensee par les reflexions sur l'autre electrode. Un champ magnetique ou electrique permet d'eliminer l'effet des electrons secondaires de faible energie. Le dispositif experimental comporte, dans le cas de la deflexion magnetique, une chambre a extrapolation et dans le cas de la deflexion electrique, une chambre a grille tres fine. L'accord avec des mesures effectuees au compteur 4 {pi} est excellent dans le cas du Sr{sup 90}-Y{sup 90} et du P{sup 32} (mieux que {+-}2%). Dans le cas du S{sup 35}, les experiences mettent en evidence l'influence du nombre atomique du support de source et en imposent le choix. Les theories sur la retrodiffusion permettent d'expliquer ces resultats. (author) [Spanish] El metodo se basa en el principio recientemente descrito por Failla y sus colaboradores: En un recinto en que se ha hecho el vacio se disponen paralelamente y a poca distancia entre si dos electrodos planos del mismo material. Sobre uno de ellos se deposita la fuente que se ha de medir. La retrodispersion en el electrodo portador de la fuente queda compensada por la reflexion en el otro electrodo. Un campo magnetico o electrico permite eliminar el efecto de los electrones secundarios de escasa energia. Cuando la deflexion se efectua por medios magneticos, el dispositivo experimental se completa por una camara de extrapolacion y cuando la deflexion es. electrica, por una camara de rejilla muy fina. En el caso del Sr{sup 90}-Y{sup 90} y del P{sup 32}, los resultados obtenidos concuerdan satisfactoriamente con los de las mediciones efectuadas con ayuda de un contador 4 {pi} (precision superior a {+-} 2%). En el caso del S{sup 35}, las eperiencias realizadas ponen de manifiesto la influencia ejercida por el numero atomico del soporte de la fuente, lo cual obliga a utilizar determinados soportes. Los resultados obtenidos pueden explicarse con ayuda de las teorias sobre la retrodispersion.

of decrease in physical activity of the pre-school children in both Montenegro and Serb Republic. Discussion and comments were integrally presented and discussed for all groups of answers to polled questions. Discussion: Dynamic development and more and more important role of physical education in modern society development as well as in the life a modern man has encouraged much more active attitude of science towards the field of the human activity (Bjelica, D. & Krivokapić, D., 2010.. Anyway, for the obvious trend of decrease in physical activity of the pre-school children, there is a need for its intensifying, in order to provide as optimal as possible influence on their mental and physical development. ``Physical development of an individual is best realized through activities that are intensified, conceived and versatile``(Bjelica, D. & Krivokapić, D., 2011. In that attempt, analysis of the position and role of the teacher as well as creating of stimulating ambient that enables, stimulates and encourages their professional development and permanent education is especially important. Taking into account the given results of this research, there is an opinion that additional education of parents of the pre-school children on importance of optimal physical activity for growth and development of the children in that period of their childhood, could partially decrease negative consequences resulting from unsatisfying level of their physical activity.

In support of the 50-MW(e) Prototype Organic Power Reactor Programme (POPR), extensive development work has been performed on aluminium powder metallurgy (ARM) products, toward their use as cladding for UO{sub 2} fuel. As part of this development work, eutectic bonding, flash butt welding, and cold-pressure welding were investigated as methods for making end closures in die fuel element cladding. Vibratory packing was studied as a means of filling APM tubes with UO{sub 2}. Out-of-pile tests were conducted to obtain information on APM-UO{sub 2} compatibility. This work revealed that, under present conditions, eutectic bonding was the most suitable method for making end closures; vibratory packing produced fuel densities in the range of 80 to 88% of theoretical density; and no APM-UO{sub 2} reaction took place in the range of POPR operating temperatures (850{sup o}F maximum fuel-cladding interface temperature). As a result o f this development work, five APM-clad UO{sub 2} prototype fuel elements have been fabricated for testing in the Organic Moderated Reactor Experiment (OMRE). Each element consisted of 24 or 25 APM-clad fuel rods, arranged in a 5 x 5 array in a nickel-plated steel or an APM fuel box. To increase surface area, the extruded APM cladding had eight fins which were spiralled to a pitch of 45 or 90e/ ft to further improve heat transfer. The fuel rod end closures were made by eutectic bonding of silver-plated aluminium end plugs to the APM tubing. The elements were instrumented to: (1) Measure cladding surface and coolant temperatures, (2) Detect fuel rod failure, (3) Change coolant velocity (means of achieving peak cladding surface temperature of 850{sup o}F), (4) Measure coolant velocity, and (5) Measure fission gas build-up. These elements have been installed in the OMRE with target fuel burn-ups of 25000 to 30000 MWd/t of uranium. As of 1 April 1963, they had achieved accumulated burn-ups ranging from 7700 to 12 000 MWd/t of uranium. Two of the elements had been removed from the reactor as a result of problems encountered with instrumentation associated with their tests. The other three elements were still in the reactor. The results of the experimental work to date give every indication that the APM-UO{sub 2} fuel system will achieve the goals set for the POPR programme. (author) [French] Dans le cadre du programme execute avec le ''Prototype Organic Power Reactor'' (POPR) de 50 MWe, des travaux importants ont ete entrepris en vue de mettre au point des produits de la metallurgie des poudres d'aluminium (APM) utilisables comme gaines d'elements combustibles en bioxyde d'uranium. Dans le cadre de ces travaux on a etudie des procedes d'emploi de melanges eutectiques, de soudure directe a Tare et de soudure par pression a froid (Kolweld) pour obturer l'extiemite des gaines. On a etudie l'emploi des vibrations pour le remplissage des gaines d'APM en combustible UO{sub 2}. Des essais hors pile ont ete faits pour recueillir des renseignements sur la compatibilite entre les produits APM et le bioxyde d'uranium. Les etudes ont revele que, dans les conditions actuelles, le recours aux melanges eutectiques etait la meilleure methode d'obturation des extremites; le remplissage par vibration a permis d'atteindre des densites de combustible de l'ordre de 80 a 88% de la valeur theorique et aucune reaction n'a ete observee entre les produits APM et UO{sub 2} dans la gamme des temperatures de fonctionnement de POPR (temperature maximum a l'interface combustible/gaine-455{sup o}C). A la suite de ces travaux preliminaires, on a fabrique cinq prototypes de cartouches de combustibles en UO{sub 2} gaine d'APM, que Gop a essayes dans le reacteur experimental a ralentisseur organique (OMRE). Chaque cartouche consistait en 24 ou 25 barreaux gaines d'APM, disposes en 5 rangees de 5 dans un recipient en acier nickele ou en aluminium APM. Pour ameliorer les echanges thermiques, les gaines d'APM extrudees etaient munies de 8 ailettes disposees selon un pas helicoidal de 45 ou 90{sup o}/30 cm. L'obturation des gaines des barreaux etait assuree par des bouchons en aluminium plaque argent, lies par alliage eutectique aux tubes APM. Les cartouches etaient equipees d'instruments permettant de: 1. Mesurer la temperature du fluide de refroidissement et la temperature superficielle des gaines; 2. Deceler les defectuosites des barreaux de combustible; 3. Modifier la vitesse du fluide de refroidissement (on pourrait ainsi obtenir des temperatures maximums de l'ordre de 455{sup o}C a la surface de la gaine); 4. Mesurer la vitesse du fluide de refroidissement; 5. Mesurer le degagement des produits de fission gazeux. Ces cartouches ont ete installees dans le reacteur OMRE pour atteindre un taux de combustion de l'ordre de 25000 a 30000 MWj/tU. Au 1er avril 1963 le taux atteint etait de 7700 a 12000 MWj/tU. Deux des cartouches ont ete retirees du reacteur a la suite de difficultes suscitees par leurs instruments de mesure. Les trois autres cartouches ont ete maintenues dans le reacteur. A ce jour, les resusltats de ces travaux experimentaux donnent a penser que le combustible APM-UO{sub 2} permettra d'atteindre les objectifs du programme de POPR. (author) [Spanish] En ejecucion del programa relativo al reactor de potencia prototipo de moderador organico de 50 MW(e) (POPR), se han llevado a cabo amplios trabajos de investigacion sobre productos elaborados por pulvimetalurgia de aluminio (PMA), con el fin de utilizarlos como revestimiento para el combustible de UO{sub 2}. Como parte de estos trabajos, se ha investigado la aptidud de los metodos de union eutectica, de soldadura a tope por chispas y de soldadura por compresion en frio ''Koldweld'', para realizar los cierres de los extremos del revestimiento de los elementos combustibles. Se ha estudiado la compresion vibratoria como procedimiento para rellenar de UO{sub 2} los tubos de PMA. Se han realizado ensayos fuera de reactor para reunir datos sobre la compatibilidad entre el material PMA y el UO{sub 2} . De estos trabajos, se deduce que, en las condiciones actuales, el metodo de union eutectica es el mas adecuado para cerrar los extremos de los revestimientos; con la compresion vibratoria, se obtuvieron densidades del combustible del orden del 80 al 88% del valor teorico, y no se produjo reaccion alguna entre el material PMA y el UO{sub 2} en el intervalo de temperaturas de funcionamiento del POPR (temperatura maxima de 850{sup o}F en la superficie de separacion entre el combustible y el revestimiento). Como resultado de estos trabajos, se han elaborado cinco elementos combustibles prototipo de UO{sub 2}, revestido con material PMA, para ensayarlos en el reactor experimental de moderador organico (OMRE). Cada elemento esta compuesto por 24 o 25 barras de combustible revestidas de material PMA, dispuestas en grupos de 5 x 5 en una caja para combustible de acero niquelado o de material PMA. Con el proposito de aumentar la superficie, el revestimiento extruido de material PMA lleva ocho aletas dispuestas en espiral con un paso de 45 o 90{sup o}/pie , cuya funcion es mejorar la transmision de calor. Los cierres de los extremos de las barras de combustible se han realizado por union eutectica de tapones de aluminio plateado a los tubos de material PMA. Los elementos combustibles estan dotados de instrumentos para: 1 . Medir las temperaturas de la superficie del revestimiento y del refrigerante; 2. Detectar defectos de las barras de combustible; 3 . Modificar la velocidad del refrigerante (como medio para obtener una temperatura maxima de la superficie del revestimiento de 850{sup o}F); 4. Medir la velocidad del refrigerante; 5. Medir la acumulacion de gases de fision. Dichos elementos se instalaron en e l reactor OMRE con el proposito de obtener grados de combustion de 25 000 a 30 000 MWd/t de uranio. El 1- de abril de 1963 habian alcanzado grados de combustion acumulativos que oscilaban entre 7700 y 12 000 MWd/t de uranio. Dos de los elementos combustibles se extrajeron del reactor a raiz de problemas suscitados por el instrumental utilizado para los ensayos. Los tres elementos restantes continuaban en el reactor. Todos los resultados de los experimentos realizados hasta la fecha parecen indicar que el sistema de combustible PMA-UO{sub 2} permitira alcanzar los objetivos fijados para el programa relativo al reactor POPR.

Sobre la base de la experiencia adquirida se calcula el costo real de construccion de una instalacion que utilice cobalto-60; dicha experiencia se aprovecha asimismo para calcular el costo de instalaciones destinadas a tratar grandes cantidades de grano. Se comparan los costos correspondientes a dos tipos de instalaciones de complejidad semejante; por este procedimiento se determina en que regiones resulta mas apropiado cada uno de ellos y en cuales cualquiera de los dos puede ser el mas indicado, segun las condiciones de emplazamiento, el nivel tecnologico local y los metodos de explotacion. Estos dos tipos de instalacion se describen con suficiente detalle para que se puedan apreciar claramente los elementos de equipo que corresponden a los costos indicados.

second part of this work is dedicated to the growth of Aluminum doped ZnO (AZO) and pure ZnO thin films on polymer substrates and on glass substrate for a comparison and the application in organic solar cells. The motivation of this part of the work is that the replacement for ITO in photovoltaic applications was tried. AZO and ZnO thin films were grown on the polymers Polyethylene terephthalate (PET) and Fluorinated ethylene propylene (FEP) by PLD method. The smooth Al doped ZnO thin films with resistivity ([rho] 80%) in visible range were grown on PET at oxygen pressure 10-3 mbar, laser fluence F = 1 J/cm2, at temperature TS = 20-175°C. The figure of merit (FOM) for the films is equal to 0.72*10-3 Ω-1. The morphology of the films was investigated by Optical Microscopy (OM) and Scanning Electron Microscopy (SEM), resistivity of the films was measured by 4 point method and optical transmission was measured by Spectrophotometer Cary 500. AZO thin films on PET are used as electron transport layer in organic solar cells with inverted structure. The sample structure was PET/AZO/ZnO/P3HT:PCBM/MoO3/Ag. The power conversion efficiency (PCE) is ⁓ 2.1 % for these organic solar cells. AZO films on FEP have wrinkles and resistivity ([rho] ⁓ 10 mΩ cm) and the change of PLD parameters does not improve the quality of the films. AZO and ZnO films were analyzed by Rutherford Backscattering Spectrometry (RBS). ZnO thin films can be stochiometrically grown on PET at pressure p = 10-1 mbar in O2 and AZO films are stochiometrically grown on PET at pressure p = 10-3 mbar in O2.(Cooperation with Prof. N. Serdar Sariciftci and Prof. Peter Bauer, Johannes Kepler University Linz). It is interesting to improve the electrical properties of AZO thin films on polymer substrates and eventually the PCE of the organic solar cells made from these samples. (author) [de

actual salt production site, some 800 km2 in size [Geuter 1913], it is now self-defined [Kurz 2006] as a magnet for tourism still steadily growing by attendance of municipalities on its northern fringe (2008: 54 municipalities, 2013: 59). The region is exemplarily for comparable regions in Austria or the Alps in terms of national/regional and transnational (UNFCCC) climate change adaptation strategies towards local/regional transfer and adjustment. Adaption remains an ambitious, cross-cutting issue with a range of societal areas and policy domains involved and to be integrated. The set of indicators to be chosen depends on the focus of the adaptation strategy. Here we focus on tourism, because it is of paramount importance for the well-being of the region from an economic point of view, but also from the perspective of sustainability and conservation of the historic heritage. In order to model the adaptive behaviour towards tourism, we work with the following twelve indicators: (1) bathing lakes / (2) skiing resorts, (4) connection to public transport, (10) bicycle ways, (5) average number of summer days / (6) heat days / (7) freezing days / (11) rain days, (8) temperature raise, (3) elevation a.s.l. / (9) slope, (12) cultural heritage. Using standardisation, we regionalise the set of indicators achieving a set of units that represent areas of uniform adaption behaviour, scaled to the policy scale and revealing in a spatial explicit manner the aggregated adaptability in terms of their potential to sustain tourism. The approach can be applied also to other transformative, yet strongly CC-affected mountain areas with a similar setting regarding their climate change adaptation potential. REFERENCES Folke, C.

Postoje studentů sportovní výchovy ke sportovní aktivitě nevidomých v Maďarsku a jejich možné příčiny Attitudes of students in sport education to the sport activity of blind people in Hungary and possible reasons for them

Full Text Available Velmi nízká účast nevidomých na sportovních aktivitách je způsobena především nedostatečnými znalostmi odborníků v oblasti sportu pro postižené osoby. Sportovní trenéři a 582 budoucí učitelé tělesné výchovy byli dotazováni na znalosti a představy o sportovních aktivitách osob s postižením, především nevidomých. Průzkum prokázal, že učitelům tělesné výchovy a trenérům, kteří se účastní sportovních aktivit určených pro postižené, dobré úmysly v zásadě neschází a že hlavní překážkou je nedostatek témat týkajících se sportu pro postižené v osnovách studijních oborů. Janečka, Kudláček a Válková (2003 zdůraznili zásadní potřebu speciálně připravených učitelů tělesné výchovy, a to především na základních školách. Osobní zkušenosti a přímý kontakt s nevidomými sportovci nemohou být nahrazeny audiovizuálními vzdělávacími metodami. Nevidomí se nemohou v důsledku svého postižení stát trenéry, takže sport pro nevidomé musí být rozvíjen s aktivní podporou a spoluprací se sportovními odborníky bez zrakového postižení. Sport pro postižené musí být vyučován jako samostatný předmět nebo alespoň jako samostatný a zdůrazňovaný úsek již stávajícího běžného předmětu, jako je teorie tréninku. Z metodického hlediska je zásadní a nenahraditelný osobní kontakt s nevidomými a také praktická setkání v průběhu výchovy (Asjborn & Tonjum, 1986. Studenti by neměli školu opouštět bez specifických znalostí o sportu pro postižené a o možných způsobech zapojení nevidomých do sportovních aktivit. Takový mnohostranný přístup ke vzdělávání je budoucí a moderní metodou výuky. The very low participation of blind people in sport is fundamentally caused by the inappropriate knowledge of experts on disabled – specific areas of sport.

y orientacion de los granos, la presencia de defectos diversos (inclusiones, poros), y tambien la evolucion misma del proceso de sinterizacion, incluyendo la formacion de los cristales, el crecimiento granular, etc. En algunos casos, el examen microscopico se puede combinar con ensayos de microdureza. Este examen de la estructura micro- cristalina representa uno de los principales metodos de control cualitativo de los materiales sinterizados, y ningun otro medio de investigacion puede reemplazarlo. 2. El grado de consolidacion, factor esencial que determina la calidad de los materiales sinterizados, se verifica tambien midiendo algunas propiedades, por ejemplo la conductividad electrica y termica, en funcion de la densidad, teniendo presente que en el caso de los materiales sinterizados, la conductividad es directamente proporcional al grado de sinterizacion. Tambien se ha ensayado un metodo adecuado para verificar la porosidad, obteniendose datos experimentales interesantes, sobre todo desde el punto de vista de la porosidad libre, que es afectada por las inclusiones gaseosas. La memoria contiene datos experimentales sobre la aplicacion de estos metodos de control a algunos materiales sinterizados, de interes para la tecnologia nuclear.

tejido oseo es menos peligrosa, eh el caso del uranio natural, que la toxicidad para el rinon. Cuando se trata de compuestos solubles de uranio altamente enriquecido cuya actividad especifica es elevada, la consideracion primordial es de caracter radiologico; los efectos quimicos en los rinones son menos peligrosos ijue la irradiacion del esqueleto qiie, por tanto, ha de considerarse como el organo critico. En este caso, es preferible tratar de evaluar la carga retenida en el cuerpo, y no la absorcion de uranio. Esta operacion se puede efectuar analizando muestras de orina tomadas no inmediatamente despues de la exposicion, sino al cabo de algun tiempo. Probablemente, el material mas indicado en la practica son las muestras tomadas al termino de unas vacaciones, pero en algunos casos puede ser necesario aceptar muestras tomadas despues de un fin de semana durante el que la persona interesada no haya concurrido al trabajo.

Las masas de los fragmentos se dedujeron de sus respectivas energias y las cargas nucleares se determinaron midiendo las energias de los rayos X-K vinculadas a las distintas masas. La magnitud y el signo del desplazamiento de Doppler permitio asignar les lineas espectrales de ios rayos gamma, a cada uno de los componentes de cada par de fragmentos. El desplazamiento de Doppler permite tambien medir independientemente la velocidad de los fragmentos y, por consiguiente, la masa de estos despues de la emision de un neutron. Los resultados de las mediciones realizadas sobre los rayos X concuerdan con la hipotesis de que la mayoria de los rayos X inmediatos emitidos durante la fision espontanea del {sup 252}Cf, son resultado de la conversion interna en los fragmentos de la fision primaria,, durante la desexcitacion de estados colectivos de baja energia. Ademas de los resultados concretos examinados en U memoiia, la consecuencia mas importante de los experimentos descritos es la demostracion de que es posible estudiar por separado las propiedades de cada fragmento de fision, identificado por sus radiaciones caracteristicas (en lugar de estudiar las propiedades de un fragmento de fision medio, con masa y carga tambien medias).

Resulta facil deducir una aplicacion de cuanto antecede a la purificacion de los metales, en particular mediante el metodo llamado de la zona fundida.

Full Text Available Cílem této studie bylo určit tělesné složení a úroveň motorické výkonnosti a zároveň posoudit změny v komponentách tělesného složení a v úrovni motorické výkonnosti v závislosti na pravidelném tréninkovém zatížení aplikovaném v rámci šestiměsíčního tréninkového programu přípravném období, tzv. "suché přípravy", ročního tréninkového cyklu 2003/2004 u skupiny mladých lyžařů běžců, žáků sportovních tříd při ZŠ T. G. Masaryka ve Vimperku a členů lyžařských oddílů Ski-klub Šumava, Libín Prachatice a Sokol Stachy ve věku 12–15 let (n = 81, v porovnání s normální populací (n = 49. Byla provedena dvě měření tělesného složení a motorické výkonnosti, na začátku a konci přípravného období (duben a říjen, tedy podruhé po šestiměsíčním tréninkovém programu. Metodou pro stanovení tělesného složení byla multifrekvenční bioimpedanční analýza (BIA, zařízení B. I. A. 2000-M, Data Input, Germany měřící celkovou impedanci při použití proměnlivé frekvence. Úroveň motorické výkonnosti byla posuzována na základě výsledků základních motorických testů. Z výsledků vyplývá, že systematický trénink realizovaný v prostředí sportovních tříd má evidentně pozitivní dopad, a to nejen v systému přípravy dětí a mládeže pro vrcholový sport, ale především z hlediska vlivu pravidelného pohybového zatížení aplikovaného nad rámec školních osnov na tělesné složení a motorickou výkonnost dospívajícího organismu. Pravidelný trénink tak může z hlediska tělesného složení působit také jako prevence vzniku nadváhy, případně obezity a s tím souvisejících dalších zdravotních rizik v dospělosti. Výsledky této studie mohou být především hodnotnou zpětnou vazbou vedoucí ke zkvalitnění tréninkové přípravy sledovaných jedinců a k obohacení programu lyžařských sportovních t

Al aumentar la presion del plasma, las celdas de conveccion dejan de superponerse y el efecto macroscopico de la inestabilidad por corriente convectiva se hace pequeno. A presiones del plasma aun mayores, las oscilaciones inestables del plasma son independientes del potencial y van acompanadas de una curvatura de las lineas de fuerza, como consecuencia de lo cual se produce un reordenamiento de las superficies magneticas. Junto con la inestabilidad por corriente convectiva, en un plasma de baja presion se desarrolla una inestabilidad por deriva, de la cual tambien se presenta en la'memoria un examen, basado en la teoria no lineal.

horizontal de varios parametros oceanograficos, el autor de la memoria indica la circulacion, hasta 150 metros de profundidad, en diferentes niveles a lo largo del litoral indio. Las secciones verticales permiten determinar la circulacion en diferentes niveles hasta 500 metros de profundidad. El nivel de las aguas estaticas parece estar situado muy por debajo de los 500 metros y varia segun el lugar y e] tiempo. La mezcla de las aguas se deduce de las relaciones tiempo-espacio. Tambien se senala en la memoria en que estaciones del ano y en que regiones se observan corrientes ascendentes y descendentes frente a la costa. La intensidad de las corrientes ascendentes es mas pronunciada en el litoral, por lo que durante la estacion correspondiente se produce una renovacion total de las masas de agua de la plataforma continental. A mayor profundidad, las masas de agua mas caudalosas son, por orden de importancia, las aguas ecuatoriales del Indico, las aguas intermedias del Antartico junto con las del mar Rojo y una ligera mezcla de las del Indico Centra], las aguas profundas del Indico y las aguas del fondo del Antartico. El autor indica la distribucion de esas masas de agua y la circulacion de las aguas profundas al norte del ecuador. Desde hace 60 anos, las aguas del fondo del Antartico parecen estar avanzando hacia el norte del ecuador tanto en el golfo de Bengala como en el mar Arabigo. Esto ha producido, en el golfo y en el mar Arabigo, un descenso del indice de salinidad. Por ultimo, el autor sugiere un programa de trabajos oceanograficos relacionados con la evacuacion sin riesgos de desechos radiactivos, particularmente en el mar Arabigo.

Full Text Available U radu je analizirana vakuum plazma sprej prevlaka VPS – Cr3C2 - 25(Ni20Cr. Upotrebljen je komercijalni prah oznake Sulzer Metco Woka 7205. Prah je deponovan sa plazma pištoljem F4 na odstojanju substrata od 340 mm. Glavni cilj rada bio je da se na smanjenom pritisku inertnog gasa Ar eliminiše razgradnja primarnog karbida Cr3C2 u karbid Cr23C6 koji bitno umanjuje mikrotvrdoću i mehaničke karakteristike prevlake. Prevlaka je deponovana debljine od 100 do 120 µm na čeličnom substratu. Mikrotvrdoća prevlake ispitana je metodom HV0.3. Vrednosti mikrotvrdoće bile su u rasponu od 1248 do 1342 HV0.3. Čvrstoća spoja prevlake ispitana je metodom na zatezanje. Utvrđeno je da čvrstoća spoja između substrata i prevlake ima vrednost 89 MPa. Mikrostruktura prevlake ispitana je tehnikom svetlosne mikroskopije. Struktura prevlake sastoji se od osnove NiCr legure sa dominantnom primarnom karbidnom fazom Cr3C2. Pored Cr3C2 faze prisutna je i faza Cr7C3. Nagrizanje prevlake urađeno je reagensom 1HNO3: 4HCl: 4H2O koji prvenstveno rastvara Ni da bi se videla raspodela karbidne faze u prevlaci. Nagrizanjem prevlake reagensom utvrđeno je da je u slojevima prevlake u velikom udelu prisutna primarna nerazgrađena karbidna faza Cr3C2 koja prevlaci daje visoke vrednosti mikrotvrdoće. / This paper analyzes vacuum plasma spray VPS - Cr3C2 - 25(Ni20Cr coatings. Commercial powder marked Sulzer Metco Woka 7205 is used. The powder is deposited with a plasma gun F4 at a distance of 340 mm from the substrate. The main objective of the study was to eliminate, at the reduced pressure of inert gas Ar, the degradation of primary Cr3C2 carbide into Cr23C6 carbide which significantly reduces the microhardness and mechanical properties of the coating. The coating is deposited with a thickness of 100 - 120 µm on a steel substrate. The microhardness of the coating was tested by HV0.3. The microhardness values were in the range of 1248 - 1342 HV0.3.

materialov aktivnoj zon'/. Primenjaetsja takzhe ogranichennyj kontrol' s pomoshh'ju poglotitelej. Odnako ni odin iz jetih metodov ne daet sushhestvennogo preimushhestva dlja togo, chtoby ego primenjat' k jenergeticheskim reaktoram- razmnozhiteljam krupnyh central'nyh atomnyh stancij, esli vnutrennij (v aktivnoj zone) kojefficient vosproizvodstva ne javljaetsja ochen' vysokim. Dolzhna byt' projavlena bol'shaja izobretatel'nost' dlja togo, cht.oby ispol'zovat' libo metod poglotitelja, libo metod regulirovki spektral'nogo smeshhenija, ne okazav ser'eznogo vlijanija na zhelaemuju i ..chasto trebuemuju jekonomiju nejtronov. Privodjatsja rezul'taty issledovanij, imejushhie-otnoshenie k usovershenstvovannym sistemam. Reaktivnost', neobhodimaja dlja upravlenija reaktorom, opredeljaetsja potrebnostjami ostanovki reaktora, toplivnym ciklom reaktora (izbytochnaja reaktivnost') i v gorazdo men'shej stepeni dominirujushhej obratnoj svjaz'ju. Trebovanija k izbytochnoj reaktivnosti, mogut byt' s uspehom opredeleny dannym toplivnym ciklom, odnako mogut znachitel'no var'irovat'sja dlja celogo rjada analogichnyh sistem, rabotajushhih na razlichnyh toplivnyh ciklah. Neobhodimuju ostatochnuju reaktivnost' mozhno ustanovit' pochti proizvol'no vyshe opredelennoj predel'noj velichiny. Odnako imeetsja celyj rjad filosofskih momentov, kotorye kasajutsja specifikacii jetogo parametra. Jeti soobrazhenija obsuzhdajutsja s tochki zrenija regulirovki reaktivnosti v sushhestvujushhih reaktorah na bystryh nejtronah, poskol'ku jeto svjazano s kolichestvom, kotoroe dejstvitel'no trebuetsja dlja jekspluatacii jenergeticheskih reaktorov-razmnozhitelej. Privodjatsja tipichnye parametry moshhnosti i parametry temperatury, zavisjashhej ot obratnoj svjazi dlja togo, chtoby opredelit' ih vlijanie na trebovanija po upravleniju reaktivnost'ju . Metody, ispol'zuemye dlja togo, chtoby predopredelit' reaktivnost' sootvetstvujushhih kontrol'nyh mehanizmov, polucheny na osnove grubyh podschetov, a takzhe s pomoshh

fisionables. Por ultimo, conviene subrayar la importancia 'global' de las relaciones que existen entre la seguridad y la administracion de los materiales nucleares; en efecto, si esta administracion no constituye siempre la base del control 'primario' de la criticidad, sigue siendo indispensable a lo largo de todo un proceso, ya que la administracion de los materiales en una parte de la planta repercute en la seguridad de las partes vecinas, en particular de la destinada al tratamiento de los desechos. (author) [Russian] Proizvodstvo, ispol'zovanie i obrabotka nekotoryh deljashhihsja materialov predstavljajut bol'shuju opasnost', osobenno opasnost', svjazannuju s kritichnost'ju. Umenie inzhenera zakljuchaetsja v tom, chtoby izbezhat' jetu opasnost' s naimen'shej cenoj i ne meshaja slishkom rabote, svjazannoj s proizvodstvom ili pererabotkoj jadernyh materialov. Dlja ustranenija jetoj opasnosti sushhestvujut,na pervyj vzgljad, tri profilakticheskih metoda: ogranichenie koncentracii rastvorov, ogranichenie massy, tshhatel'nyj vybor geometrij. Tendencija sostoit v maksimal'nom ispol'zovanii tret'ego metoda, inache govorja, v rabote s sistemami dopolnitel'noj avarijnoj zashhity. Odnako na jadernyh ustanovkah imeetsja mnogo sistem dopolnitel'noj avarijnoj zashhity, i primenenie togo ili drugogo iz dvuh metodov stanovitsja neobhodimym. Jeti metody imejut otnoshenie k obrashheniju s jadernymi materialami. Na ustanovkah, gde rabotajut s nebol'shimi kolichestvami deljashhihsja materialov, zachastuju mozhno obespechit' jadernuju bezopasnost', dopuskaja dlja kazhdogo pomeshhenija takuju massu deljashhegosja materiala, kotoraja nizhe minimal'noj kriticheskoj massy. V otnoshenii bolee krupnyh ustanovok podobnyj kontrol', kotoryj polnost'ju osnovan na obrashhenii s materialami, stanovitsja nevozmozhnym. Izuchim, kak vygljadit svjaz' mezhdu obrashheniem i jadernoj bezopasnost'ju na zavode po obrabotke obluchennogo topliva vodnym metodom (toplivo na osnove prirodnogo urana). Takoj zavod
