The article reports the radiocarbon investigation of Anzapalivoro, the largest za baobab (Adansonia za) specimen of Madagascar and of another za, namely the Big cistern baobab. Several wood samples collected from the large inner cavity and from the outer part/exterior of the tree were investigated by AMS (accelerator mass spectrometry) radiocarbon dating. For samples collected from the cavity walls, the age values increase with the distance into the wood up to a point of maximum age, after which the values decrease toward the outer part. This anomaly of age sequences indicates that the inner cavity of Anzapalivoro is a false cavity, practically an empty space between several fused stems disposed in a ring-shaped structure. The radiocarbon date of the oldest sample was 780 ± 30 bp, which corresponds to a calibrated age of around 735 yr. Dating results indicate that Anzapalivoro has a closed ring-shaped structure, which consists of 5 fused stems that close a false cavity. The oldest part of the biggest za baobab has a calculated age of 900 years. We also disclose results of the investigation of a second za baobab, the Big cistern baobab, which was hollowed out for water storage. This specimen, which consists of 4 fused stems, was found to be around 260 years old.

The objective of the measurements was determining the neutron flux in the RA reactor core. Since the number of fuel channels is increased from 56 to 68 within the VISA-2 project, it was necessary to attain criticality of the RA reactor and measure the neutron flux properties. The 'program of RA reactor start-up' has been prepared separately and it is included in this report. Measurements were divided in two phases. First phase was measuring of the neutron flux after the criticality was achieved but at zero power. During phase two measurements were repeated at several power levels, at equilibrium xenon poisoning. This report includes experimental data of flux distributions and absolute values of the thermal and fast neutron flux in the RA reactor experimental channels and values of cadmium ratio for determining the neutron epithermal flux. Data related to calibration of regulatory rods for cold un poisoned core are included. [Serbo-Croat] Svrha merenja je odredjivanje neutronskog fluksa u reaktoru RA. S obzirom na uvecani broj tehnoloskih kanala of 56 na 68 u vezi projekta VISA-2, bilo je potrebno ponovo dovesti reaktora RA do kriticnosti i izvrsiti merenja karakteristika fluksa neutrona. Posebno je pripremljen 'program pustanja u pogon reaktora RA', koji je sadrzan u ovom dokumentu. Program merenja bio je podeljen na dve faze. Prva faza je merenje fluksa pre podizanju reaktora na nominalnu snagu. Slicna merenja vrsena su i na vecim snagama u drugoj fazi, pod uslovima ravnoteznog zatrovanja reaktora ksenonom, jer se tada pokazuju izvesne promene u odgovarajucim karakteristikama fluksa neutrona. Ovaj izvestaj sadrzi merene vrednosti raspodele fluksa i apsolutne vrednosti termalnih i brzih neutrona kao i kadmijumskih odnosa koji su korisceni za odredjivanje fluksa epitermalnih neutrona. Opisana je kalibracija regulacionih sipki za hladan nezatrovan reaktor.

Full Text Available En esta contribución se da a conocer el primer registro de termiteros fósiles para la región Mesopotámica de Argentina, y su disposición espacial, al tiempo que se discuten sus afinidades taxonómicas e implicancias paleoambientales. Las estructuras fósiles pertenecen a nidificaciones de insectos sociales atribuibles a miembros de la Familia Termitidae, y se ubican en la zona de contacto entre la base de la Fm. Toropí/Yupoí (Pleistoceno tardío y el tope de la Fm. Ituzaingó (Mioceno tardío-Plioceno. Se las identifica en los alrededores del Arroyo Toropí (28°36’ S y 59°02’ W, Departamento Bella Vista, provincia de Corrientes. El estudio de las nidificaciones y su disposición espacial se realizó en cinco campos de termiteros mediante su relevamiento y descripción morfológica. La morfología de las estructuras estudiadas coincide claramente con la de los nidos de termitas, en donde resulta característica una fuerte muralla externa. La caracterización de campo, yacencia, desarrollo, frecuencia, tamaños e interrelaciones de los termiteros fósiles y actuales sugieren una estrecha similitud con montículos del género Cornitermes. La morfología presente muestra también cierta semejanza con Tacuruichnus farinai, descripta para el Piso/Edad Marplatense (Plioceno de la región Pampeana. Por otro lado, el análisis fitolítico indicó que las cantidades y las morfologías fitolíticas son semejantes tanto en los termiteros actuales como en los fósiles. Desde un punto de vista paleoambiental, la abundancia de estos termiteros en el contacto entre las mencionadas unidades indicaría la existencia de suelos bien desarrollados, con abundante vegetación graminosa y condiciones húmedas y cálidas con estacionalidad marcada.

Good understanding of the nuclear properties of the materials in the reactor core is essential for reactor operation. One of the fundamental properties is the resonance absorption of the fuel, which is directly included in the reactor calculation through resonance escape probability and influences the choice of the materials quality in the core. This paper describes the measurement of resonance absorption integral of the natural uranium as a function of the S/M ratio. Improved experiment planning and analysis of results, as well as improvement of the ROB-1 reactor oscillator device related to the interpretation of results and decrease of reactor drift variations during measurement enabled higher precision of results compared to previous experiments. Poznavanje osobina nuklearnih karakteristika materijala koji ulaze u jezgro nuklearnog reaktora predstavlja bitan faktor u njegovom rezimu rada. Jedna od osnovnih je svakako rezonantna apsorpcija goriva, cija velicina - preko faktora rezonantnog izbegavanja - direktno ulazi u proracun nuklearnih reaktora i utice na izbor kvaliteta materijala koji ga sacinjavaju. U radu se opisuje merenje rezonantnog apsorpcionog integrala prirodnog urana u funkciji odnosa S/M. Bolja postavka eksperimenta i interpretacija rezultata, s jedne strane, i poboljsanje uredjaja reaktorskog oscilatora ROB-1 /1/ u pogledu analize podataka i smanjenja promene drifta reaktora u toku merenja, s druge strane, daju znacaj ovom radu u pogledu dobijanja preciznijih rezultata u odnosu na ranije /2/ (author)

Morfología comparada de los dientes humanos fósiles de Ibeas (Sierra de Atapuerca, Burgos

Full Text Available This paper contains a morphological and comparative study of 68 human fossil teeth recovered from the "Sima de los Huesos" site of the Cueva Mayor-Cueva del Silo karst system (Sierra de Atapuerca, Ibeas de Juarros, Burgos. The morphology of the Ibeas teeth conforms with a pattern of expansion of the anterior dentition characterizing all the Middle Pleistocene human populations, and with a pattern of structural reduction of the posterior teeth characterizing the European population of that period. The Ibeas teeth share several morphological traits with those of other European, North African and Asian Middle Pleistocene fossils. However, the tooth morphology of the European group, in which the Ibeas fossils are included, shows remarkable differences with that of the other groups. This fact permits to reinforce the thesis that a distinctive hominid lineage was established in Europe during the Middle Pleistocene. On the other hand, the Ibeas teeth bring forward new evidence to support the hypothesis of a close filogenetic relationship between the Middle Pleistocene European population and the Nearderthals and, accordingly, of a local evolution during that period and the Early Upper Pleistocene.Este trabajo contiene el estudio morfológico comparado de un total de 68 dientes humanos fósiles recuperados en la Sima de los Huesos, yacimiento situado en el sistema kárstico Cueva Mayor-Cueva del Silo (Sierra de Atapuerca, Ibeas de Juarros, Burgos.

Full Text Available Mikroreaktori su reaktorski sustavi izvedeni u mikroskopskom mjerilu, a zbog svoje velike međufazne površine imaju prednosti u odnosu na klasične – makroreaktorske sustave. Odabir materijala za izradu mikroreaktora ovisi o vrsti reakcije koja se provodi u sustavu, kompatibilnosti otapala i materijala, mehaničkim zahtjevima te o cijeni i dostupnosti na tržištu. Materijali koji se najčešće upotrebljavaju za izradu su različite vrste stakla, keramike, metali te polimerni materijali. Ovisno o materijalu odabiru se postupci izrade, a najčešći postupci su jetkanje, litografija, pjeskarenje, strojna obrada, injekcijsko prešanje te aditivni postupci izrade. Cilj ovog rada je predstaviti najčešće materijale i postupke izrade mikroreaktora.

This paper contains the study of the literature concerned with physical properties of the tritium, problems of detection control of the tritium level in the atmosphere in the vicinity of heavy water reactors. It is stated that a complete and efficient control of tritium activity, from radiation protection point of view can be achieved only by simultaneous triple measurements: direct measurement of tritium in the air by stationary or movable instruments; air sampling and measurement of activity by laboratory instrumentation; and measurement of tritium in the bio-material of the personnel who have inhaled air contaminated with tritium. Laboratory equipment was adapted for tritium detection in air samples. A method for measuring the specific tritium activity was developed and implemented. The tritium level and distribution in the air were measured during exchange of the fuel channel in the RA reactor. The obtained results indicate that tritium could be dangerous for the staff involved. Proucena je literatura u kojoj se tretiraju osnovne fizicke karakteristike tricijuma, kao i problemi detekcije i kontrole u vazduhu kod teskovodnih nuklearnih reaktora. Utvrdjeno je da kompletna i efikasna kontrola aktivnosti tricijuma, sa aspekta zastite od zracenja, moze biti ostvarena samo ako se vrse istovremeno trostruka merenja: merenje aktivnosti tricijuma u vazduhu direktno, prenosnim ili stacioniranim instrumentima; uzimanje uzoraka vazduha i merenje aktivnosti na laboratorijskoj aparaturi; i merenje aktivnosti tricijuma u biomaterijalu osoblja koje je udisalo vazduh kontaminiran tricijumom. Izvrsena je adaptacija laboratorijske aparature za potrebe detekcije tricijuma u uzorcima vazduha. Razradjen je i uhodan postupak merenja koncentracije aktivnosti tricijuma u uzorcima vazduha. Izvrsena su merenja i dobijeni su rezultati o nivou i raspodeli tricijuma u vazduhu pri operaciji zamene kanala sa gorivom na reaktoru RA u Vinci. Dobijeni rezultati ukazuju na opasnost koju po radno

Friction and wear behavior of TiC particle reinforced ZA43 matrix composites

Institute of Scientific and Technical Information of China (English)

谢贤清; 张荻; 刘金水; 吴人洁

2001-01-01

TiC/ZA43 composites were fabricated by XDTM and stirring-casting techniques. The tribology properties of the unreinforced ZA43 alloy and the composites were studied by using a block-on-ring apparatus. Experimental results show that the incorporation of TiC particles improves the microstructure of ZA43 matrix alloy. The coefficient of friction μ and the width of worn groove decrease with the increase of TiC volume fraction φ(TiC). The width of worn groove and μ of the composite during wear testing increase with increasing the applied load. Metallographic examinations reveal that unreinforced ZA43 alloy has deep ploughing grooves with obvious adhesion phenomenon, whereas TiC/ZA43 composites have smooth worn surface. Delamination formation is related to the fatigue cracks and the shear cracks on the surface.

The ZaP Flow Z-Pinch Project

International Nuclear Information System (INIS)

Shumlak, U.; Nelson, B. A.

2005-01-01

The results from the ZaP experiment are consistent with the theoretical predictions of sheared flow stabilization. Z pinches with a sheared flow are generated in the ZaP experiment using a coaxial accelerator coupled to an assembly region. The current sheet in the accelerator initially acts as a snowplow. As the Z pinch forms, plasma formation in the accelerator transits to a deflagration process. The plasma exits the accelerator and maintains the flow in the Z pinch. During the quiescent period in the magnetic mode activity at z=0 cm, a stable Z pinch is seen on the axis of the assembly region. The evolution of the axial velocity profile shows a large velocity shear is measured at the edge of the Z pinch during the quiescent period. The velocity shear is above the theoretical threshold. As the velocity shear decreases towards 0.1kV A , the predicted stability threshold, the quiescent period ends. The present understanding of the ZaP experiment shows that it may be possible for the Z pinch to operate in a steady state if the deflagration process can be maintained by constantly supplying neutral gas or plasma to the accelerator

Calorimetric dosimetry of reactor radiation; Kalorimetriska dozimetrija reaktorskog zracenja

Energy Technology Data Exchange (ETDEWEB)

Radak, B; Markovic, V; Draganic, I [Institute of Nuclear Sciences Boris Kidric, Odeljenje za radijacionu hemiju, Vinca, Beograd (Serbia and Montenegro)

1961-12-15

Calorimetric dosimetry of reactor radiation is relatively new reactor dosimetry method and the number of relevant papers is rather small. Some difficulties in applying standard methods (chemical dosemeters, ionization chambers) exist because of the complexity of radiation. In general application of calorimetric dosemeters for measuring absorbed doses is most precise. In addition to adequate choice of calorimetric bodies there is a possibility of determining the yields of each component of the radiation mixture in the total absorbed dose. This paper contains a short review of the basic calorimetry methods and some results of measurements at the RA reactor in Vinca performed by isothermal calorimeter. Kalorimetrijska dozimetrija reaktorskog zracenja je relativno nova metoda dozimetrije reaktora i broj do sada objavljenih radova je vrlo skroman. S obzirom na slozenu prirodu zracenja postoje neke teskoce pri radu sa standardnim metodama (hemijski dozimetri, jonizacione komere). U principu, upotreba kalorimetra za merenje apsorbovanih doza je najegzaktnija. Osim toga, uz pogodni izbor kalorimetrijskih tela postoji mogucnost za odredjivanje doprinosa pojedinih komponenti smese zracenja u totalnoj apsorbovanoj dozi. U tekstu je dat kratak pregled osnovnih metoda kalorimetrije i neki rezultati merenja sa izotermskim kalorimetrom na reaktoru RA u Vinci.

Prijedlog dorade pravnog režima za nautički turizam radi podizanja njegove konkurentnosti

Full Text Available Cilj rada je predložiti određene dorade u domaćem pravnom režimu za nautički turizam radi podizanja njegove konkurentnosti. Pomorskopravni odnosi su specifični zbog međunarodnog karaktera plovidbe i konkurencije pravnih režima više država u uređenju pravnih odnosa koji proističu iz plovidbe. Zato, sugerira autor, za ocjenu da li je neka država pomorska nije odlučna dužina ili razvedenost njene obale, već da li njena vlada razumije specifične odnose vezane za pomorstvo i da li ih uređuje na način koji omogućuje razvoj pomorske privrede. Europska unija je prepoznala specifičnost pomorstva i dopustila svojim članicama da urede porezni sustav za brodarstvo drugačije od općeg poreznog sustava. Sada bi, drži autor, poseban sustav za uređenje nautičkog turizma trebalo kreirati i za jahte, u kojem niz odnosa – vezanih za tu djelatnost – treba urediti drugačije od općih odredbi. Sve to u cilju podizanja konkurentnosti hrvatskog nautičkog turizma, koji se bori na tržištu Sredozemlja s drugim, posebice za velike jahte, vrlo atraktivnim destinacijama. U radu se obrađuju administrativne procedure; kabotaža u uvjetima članstva u Europskoj uniji; porez na dodanu vrijednost na najamninu jahti; boravak posade jahti u Hrvatskoj; porezi na dohodak i doprinosi članova posade jahte; porez po tonaži i privremeni uvoz jahti. Posebice se razmatra članstvo Hrvatske u Europskoj uniji koje donosi prilike, ali i nameće ograničenja za standardne mjere protekcionizma i intervencionizma koje su povijesno koristile zemlje u razvoju da dostignu one razvijene. Ovaj je rad dio prijedloga većeg zahvata u zakonodavstvo za izmjenu određenog broja zakonskih rješenja primjenjivih na nautički turizam, koja nisu logična ili optimalna za tu gospodarsku granu.

During 1982 the Ra reactor was operated at 2 MW power with the initial core configuration with 80% enriched fuel. The reactor power would be limited until the ventilation system is be repaired and the emergency cooling system built. The limited operation regime during 1982 had twofold application: as regular regime for the users according to their demands and for experiments related to the testing operation at 2 MW power level. The following reactor physics activities were affected by this operational regime: methods for regular operation control (determining power density and burnup distribution, reactivity variation, et,); measurement of utilization parameters (spatial distribution of the neutron flux); analysis of origin and consequences of irregularities during operation (control of heavy water and gas composition by gamma spectrometry, control of fission products, control of the heavy water purification system); safety analyses including future new systems (emergency cooling and ventilation) [Serbo-Croat] Reaktor RA je tokom 1982 godine radio sa pocetnom konfiguracijom jezgra sa 80% obogacenim gorivom na snazi od 2 Mw. Snaga je ogranicena dok se ne izvrsi rekonstrukcija sistema ventilacije i ugradnja sistema za udesno hladjenje. Rezim rada na ogranicenoj snazi koriscen je u 1982. godini dvojako: kao normalni radni rezim za potrebe korisnika i za eksperimenta u okviru probnog rada na snazi 2 MW. Ovim rezimom rada uslovljene su delatnosti u okviru reaktorske fizike na sledece oblasti: metodologija kontrole redovnog radnog rezim (odredjivanje raspodele snage i izgaranja goriva, promene reaktivnosti, itd.), merenje eksploatacionih parametara reaktora (prostorna raspodela neutronskog fluks, i sl,), analiza uzroka i posledica pojava neregularnosti u radu fizickim metodama (kontrola sadrzaja teske vode i gasa gama spektometrijom, kontrola fisionih produkata, kontrola sistema za preciscavanje teske vode), sigurnosne analize ukljucujuci buducu izgradnju novih sistema

Soler-López, Luis R.; Licha-Soler, N.A.

2014-01-01

Lago Loíza is a reservoir formed at the confluence of Río Gurabo and Río Grande de Loíza in the municipality of Trujillo Alto in central Puerto Rico, about 10 kilometers (km) north of the town of Caguas, about 9 km northwest of Gurabo, and about 3 km south of Trujillo Alto (fig. 1). The Carraizo Dam is owned and operated by the Puerto Rico Aqueduct and Sewer Authority (PRASA), and was constructed in 1953 as a water-supply reservoir for the San Juan Metropolitan area. The dam is a concrete gravity structure that is located in a shallow valley and has a gently sloping left abutment and steep right abutment. Non-overflow sections flank the spillway section. Waterways include an intake structure for the pumping station and power plant, sluiceways, a trash sluice, and a spillway. The reservoir was built to provide a storage capacity of 26.8 million cubic meters (Mm3) of water at the maximum pool elevation of 41.14 meters (m) above mean sea level (msl) for the Sergio Cuevas Filtration Plant that serves the San Juan metropolitan area. The reservoir has a drainage area of 538 square kilometers (km2) and receives an annual mean rainfall that ranges from 1,600 to 5,000 millimeters per year (mm/yr). The principal streams that drain into Lago Loíza are the Río Grande de Loíza, Río Gurabo, and Río Cañas. Two other rivers, the Río Bairoa and Río Cagüitas, discharge into the Río Grande de Loíza just before it enters the reservoir. The combined mean annual runoff of the Río Grande de Loíza and the Río Gurabo for the 1960–2009 period of record is 323 Mm3. Flow from these streams constitutes about 89 percent of the total mean annual inflow of 364 Mm3 to the reservoir (U.S. Geological Survey, 2009). Detailed information about Lago Loíza reservoir structures, historical sediment accumulation, and a dredge conducted in 1999 are available in Soler-López and Gómez-Gómez (2005).

Relación del índice de cristalinidad (IC con la edad y el contenido de iones F y CO3 en muestras de vertebrados fósiles

Full Text Available The crystalline fraction of enamel, dentin and metapodial bone of modern and fossil mammals were studied by X-ray diffraction analysis. The powdered samples were collected from several equids, giraffids, rhinocerotids and proboscideans of Spanish Neogene deposits. Changes in the crystallinity index (CI of apatite are particularly useful to estimate later diagenetic changes in the fossil material. The enamel displays larger CI than dentine and metapodial bone since they have a more dense structure; furthermore there is not a clear relationship between the CI enlargement and the geological age of samples. In addition, the fluorine content increases during the fossilization process and accordingly the parameter CI increases in fossil samples. The carbonate enrichment is not linked to the age of the deposits; however this carbonate increase in enamel, dentine and metapodial bone reduces the CI parameter. The host sediments play an essential role in the crystallinity changes observed in fossil bones; e.g., in the silica sands case, samples display a high CI while in the claystone and chalks case, they display a lower crystallinity index.Se ha determinado el índice de cristalinidad (IC mediante difracción de rayos X de muestras actuales y fósiles pertenecientes a esmalte, dentina y hueso de metápodo de équidos, jiráfidos, rinocerótidos y proboscídeos de diferentes yacimientos neógenos españoles. Con estos valores de la cristalinidad del apatito se estima semicuantitativamente la evolución de los cambios diagenéticos ocurridos en el material óseo fósil. Se ha observado que el esmalte presenta un IC mayor que la dentina y hueso de metápodo, debido a su estructura más compacta. Sin embargo, no hay una correlación clara entre el incremento de la cristalinidad y la edad de las muestras. Además, el contenido de flúor aumenta durante los procesos de fosilización y como consecuencia aumenta el IC en las muestras fósiles. Por otro lado, el

Full Text Available Entre los indicadores biológicos lacustres más utilizados en las reconstrucciones ambientales, se encuentran el polen, los ostrácodos y las diatomeas, y entre los insectos, los coleópteros y los quironómidos. Este grupo ha cobrado gran importancia en los últimos tiempos, debido a los resultados prometedores que se han obtenido en reconstrucciones climáticas realizadas en América del Norte y Europa. En América del Sur, el uso de los quironómidos fósiles en estudios cuaternarios es relativamente limitado, principalmente por su escaso conocimiento taxonómico regional. La mayor parte de estos estudios fueron realizados en lagos glaciares patagónicos de Argentina y Chile. Las larvas de quironómidos constituyen una valiosa herramienta paleolimnológica, por ser un grupo de organismos altamente sensible a cambios ambientales, tanto naturales como artificiales. Además, es un grupo de insectos ampliamente distribuido y con una abundancia y diversidad relativamente altas. Sus cápsulas cefálicas se preservan en los sedimentos lacustres y poseen caracteres importantes que permiten identificar géneros y muchas veces especies. El estudio de los ensambles de quironómidos en sedimentos lacustres puede ser utilizado con distintos objetivos, por ejemplo, para estudios de eutrofización, ya que responden rápidamente a cambios en la concentración de nutrientes, materia orgánica y otros elementos, como metales pesados. No obstante, uno de los potenciales más importantes de este grupo de insectos es su sensibilidad a los cambios de temperatura, por este motivo, la aplicación más importante de su estudio en sedimentos se centra en las reconstrucciones climáticas. Esta contribución es una síntesis de los resultados de los trabajos publicados en la Patagonia argentina y chilena, sobre la base del uso de los quironómidos fósiles en reconstrucciones paleoambientales.

Funzioni lessicali e aspettuali del preverbo za- nella Povest’ vremennych let

Luisa Ruvoletto

2012-01-01

Full Text Available This paper examines the forms of the za- prefixed verbs in the Old Russian text Povest’ vremennych let (11th-12th centuries. The study shows how this prefix, like other prefixes in Old Russian, has both lexical and aspectual functions, and that there is considerable interaction between the semantics of the prefix and the meaning of the unprefixed verb. Some groups of verbal forms can be found in which the prefix fulfils specific meanings. This analysis allows the detection of some “embryonic” forms of the lexical meanings and aspectual functions expressed in the modern Russian by the za- prefixed verbs in one of the oldest East Slavic texts. This is clearly of interest when delineating the semantic evolution of this prefix and its aspectual function in a diachronic perspective.

Research highlights: → ZA27 with 5% SiC, ZrO2 or C particles are synthesized by stirring then squeezed. → Particles refine the structure. 50 MPa decreases porosity% and increases density. → α and β nucleation temperatures of the composites are lower than those of the matrix. → Particles accelerate age hardening and increase peak hardness of the composites → Particles reduce the CTEs of composites compared to those of the matrix. - Abstract: ZA27 alloy based composites were synthesized by stirring method, followed by squeeze casting. Stir casting was employed successfully to incorporate 5 vol.% of various reinforcement particulates, namely, SiC, ZrO 2 or C. The porosity in the composites was decreased by squeeze pressure. The presence of particles and/or application of squeeze pressure during solidification resulted in considerable refinement in the structure of the composites. The microstructures, X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDXA) results indicated that no significant reactions occurred at the interface between the SiC or C particles and ZA27 alloy. However, in case of ZrO 2 reinforced ZA27, the ZrO 2 reacted with Cu present in the molten ZA27 alloy, forming Cu 5 Zr. Thermal analysis showed that both α and β nucleation and growth temperatures of the composites were lower than those of the ZA27 alloy. The presence of particles in the as-cast or squeezed composites led to not only an accelerated age hardening response, but also an increase in the peak hardness of the composites. The values of coefficient of thermal expansion (CTE) of the composites were drastically lower as compared to those of the ZA27 alloy. The tensile properties of the composites decreased as a result of the addition of the particles. Scanning electron microscope (SEM) pictures of the composites indicated that cracks mainly initiated at particle-matrix interface, propagated through the matrix and linked up with other cracks leading to failure of the

Full Text Available An investigation has been carried out on the synthesis and characterization of ZA-27 alloy composites reinforced with zinc oxide nanoparticles. This was aimed at developing high performance ZA-27 matrix nanocomposite with low density. The particle size and morphology of the zinc oxide (ZnO nanoparticles were investigated by Transmission Electron Microscope (TEM and the elemental composition was obtained from Energy Dispersive Spectroscopy (EDS attached to TEM and X-ray fluorescence spectroscopy (XRF. ZA-27 nanocomposite samples were developed using 0, 1, 2, 3, 4 and 5 wt% of ZnO nanoparticles by double steps stir casting technique. Mechanical properties and Microstructural examination were used to characterize the composite samples produced. The results show that hardness and ultimate tensile strength of the composite samples increased progressively with increase in weight percentage of ZnO nanoparticles. Increase in Ultimate tensile strength (UTS of 10.2%, 21.1%, 22.3%, 35.5%, 33.4% and increase in hardness value of 8.2%, 14.8%, 21.7%, 27.9%, 27.1% were observed for nanocomposites reinforced with 1 wt%, 2 wt%, 3 wt%, 4 wt%, and 5 wt% ZnO nanoparticles respectively in comparison with unreinforced alloy. It was generally observed that composite sample containing 4 wt% of reinforcement has the highest tensile strength and hardness values. However, the fracture toughness and percent elongation of the composites samples slightly decreased with increase in ZnO nanoparticles content. Results obtained from the Microstructural examination using optical microscope and Scanning Electron Microscope (SEM show that the nanoparticles were well dispersed in the ZA-27 alloy matrix.

Le sexe est indéterminé, l'âge, peu précis, se situe aux environs de 3 ans. Les caractéristiques du sédiment et les dimensions probables de la fosse conduisent à une évaluation de la profondeur atteinte par la déflation éolienne en cet endroit depuis l'époque de l'enterrement: environ 50 cm. Se da cuenta del hallazgo de una tumba de niño en el taller Nº 4 del sitio PV22-12, Pampa de los Fósiles. Esta tumba estaba cubierta por los desechos de talla de puntos del tipo conocido bajo el nombre de Paiján.

El sexo es indeterminado y la edad no muy precisa, se trata de un niño de alrededor de 3 años. Las características del sedimento y las posibles dimensiones de la fosa de entierro llevan a hacer una evaluación de la erosión eolica desde el tiempo del entierro: aproximadamente 50 cm.

Full Text Available Avtorica predstavi pomen izobraževanja starejših odraslih za dejavno staranje v dolgem prehodnem obdobju, imenovanem »čas med delom, upokojitvijo in starostjo«. Ta koncept prehodnega obdobja, prehoda v starost, namreč danes nadomešča starejši koncept pokoja. V tem času ljudje v poznejših letih življenja opravljajo plačano delo, se izobražujejo, se (občasno vračajo na trg dela, delajo prostovoljno. Avtorica piše o prebivalstvenih spremembah in o pomenu izobraženosti vseh in vseh skupin starejših odraslih za soočanje s staranjem družbe. Dušana Findeisen zastane pri vprašanju značilnosti izobraževalnih programov za starejše odrasle, obravnava vrednote, nosilce in oblike izobraževanja starejših. Nazadnje opiše slovensko univerzo za tretje življenjsko obdobje kot konceptualno eno najbolj celostno domišljenih oblik in modelov izobraževanja ljudi v poznejših letih življenja.

During 1972, the total production was 31151 MWh which is 3.8% higher than planned. The reactor was used for irradiation and experiments according to the demand of 381 users, of which 340 from the Institute and 41 external users. This report contains detailed data about reactor power and experiments performed in 1972. Discrepancies from the action plan, meaning higher production was achieved due to special demands of the users. Total number of interruptions was lower than during all the previous years, and were caused mainly due to announced power cuts. There was only on scram shutdown during this year caused by a false signal of the reactor control instrumentation. There were no longer interruptions. One shorter interruption (shorter than 24 hours) caused by removal of a UO{sub 2} capsule from the core, placed there for measuring heat transfer. Total personnel exposure dose was lower than during previous years. One accident caused contamination with gases and aerosols containing mainly shot-living isotopes. Decontamination od surfaces was less than during previous years. Practically there was no surface contamination that would demand action of the decontamination team, except for the regular decontamination after refueling. It was concluded that the successful operation in 1972 has a special significance having taking in account the financial crisis caused by the unresolved status of the reactor. It is emphasised, in the plan for the next year that there is an urgent need of making a long-term plan of rector application. It is indispensable to finish preparatory tasks for replacing the fuel with the highly enriched fuel elements by 1974, and building the core emergency cooling system.

Full Text Available We have studied the fossil Rhinocerotidae from Buñol (Valencia, Spain. It is realized as stratigraphic synthesis of the deposit and dated as Orleanium Mammal Age (lower-middle Aragonium, which is equivalent to the 4b Neogene MammaL Unit (zonation of Mein, 1976. We conclude that the fossil association is a thanatocoenosis, with strongly rounded elements. The paleoenvironment, in which this association was accumulated, was a marsh zone in the distal part of an alluvial fan. Two species of Rhinocerotidae have been determined, one of the ,genus Acerotherium and another of the genus Dicerorhinus. The second is more abundant than the former and probably it would be adapted to a marshy habitat. We describe and figure the more representative material of both species.

Spatial and time dependence relation of neutrons from fission and other reactions in the reactor core result in non Poisson fluctuations of neutron density. Analytical formula developed for auto-correlation function includes physical parameters which characterize time behaviour of neutrons in the reactor system. Since auto-correlation function can be easily measured, it is a useful tool for experimental determination of these parameters. Noise from the ionization chamber was measured and analyzed by a digital computer. measurements were analyzed completely in the time domain (auto-correlation functions). This enabled separating the noise caused by neutron detection from the noise from neutron density fluctuation in the reactor. All the results can be analyzed by spatial independent reactor theory. Physical analysis of reactor noise was limited to determination of {beta}/l ratio from auto-correlation measurements at 0.5 W power level (RB reactor in Vinca). Three different reactor core lattices were analyzed (lattice pitch 8 cm, 11.3 cm and 14 cm). It was shown that parameter {beta}/l could be determined from auto-correlation measurements of neutron density with high precision (few percents) Prostorna i vremenska povezanost neutrona koji nastaju u fisiji i drugim procesima koji se desavaju u reaktoru dovodi do ne Poisson-ovih fluktuacija neutronske gustine. Analiticka formula, razvijena za autokorelacionu funkciju ovih fluktuacija, sadrzi fizicke parametre koji karakterisu vremensko ponasanje neutrona u reaktorskom sistemu. Kako autokorelaciona funkcija moze lako da se meri, ona je korisno sredstvo za eksperimentalno odredjivanje ovih parametara. Sum iz jonizacione komore digitalno je meren i analiziran u digitalnom racunaru. Merenja su kompletno analizirana u vremenskom domenu (autokorelacione funkeije). To je olaksalo razdvajanje suma izazvanog procesom neutronske detekcije od suma koji potice od fluktuacija neutronske gustine u reaktorskom sistemu. Svi rezultati

Pan Fusheng; Yang Mingbo; Cheng Liang

2010-01-01

The effects of minor Sc on the as-cast microstructure, mechanical properties and casting fluidity of the ZA84 magnesium alloy were investigated. The results indicate that the Mg 32 (Al,Zn) 49 phase in the ZA84 alloy is refined with the addition of 0.12-0.35 wt.% Sc, and the formation of the Mg 32 (Al,Zn) 49 phase is suppressed. An increase in Sc amount from 0.12 wt.% to 0.35 wt.% causes the morphology of the Mg 32 (Al,Zn) 49 phase to gradually change from coarse continuous and/or quasi-continuous net to relatively fine quasi-continuous and/or disconnected shapes. In addition, it is shown that the tensile and creep properties of the ZA84 alloy are improved, but the casting fluidity of the alloy is decreased with the addition of 0.12-0.35 wt.% Sc.

Full Text Available Calcareous nannofossils from two boreholes (Campo Bola and Sur Río Chico in the subsurface of eastern Austral Basin, Santa Cruz Province, Argentina, allowed the identification of Early to Middle Paleocene, Early to Middle Eocene and Late Eocene to Early Oligocene assemblages. These assemblages match the formations logged in the boreholes Campo Bola, Man Aike and Río Leona respectively, and represent three paleogene sedimentary cycles within the basin. These results permitted the reinterpretation of previous data from an adjacent borehole (Cerro Redondo. The southern boreholes (Cerro Redondo and Sur Río Chico yield an Early to Middle Paleocene calcareous nannofossil assemblage and an almost continuous record of nannofossils from Early Eocene to Early Oligocene. A discontinuity is interpreted by the absence of Late Paleocene assemblages. The northern borehole (Campo Bola yield only late Early Eocene to Early Oligocene assemblages.

Ralstonia eutropha's Poly(3-hydroxybutyrate)(PHB) polymerase PhaC1 and PHB depolymerase PhaZa1 are phosphorylated in vivo.

Science.gov (United States)

Jüngert, Janina R; Patterson, Cameron; Jendrossek, Dieter

2018-04-20

In this study, we screened PHB synthase PhaC1 and PHB depolymerase PhaZa1 of Ralstonia eutropha for the presence of phosphorylated residues during the PHB accumulation and PHB degradation phase. Thr373 of PHB synthase PhaC1 was phosphorylated in the stationary growth phase but was not modified in the exponential and PHB accumulation phases. Ser35 of PHB depolymerase PhaZa1 was identified in phosphorylated form both in the exponential and in the stationary growth phase. Additional phosphosites were identified for both proteins in sample-dependent forms. Site-directed mutagenesis of the codon for Thr373 and other phosphosites of PhaC1 revealed a strong negative impact on PHB synthase activity. Modification of Thr26 and Ser35 of PhaZa1 reduced the ability of R. eutropha to mobilize PHB in the stationary growth phase. Our results show that phosphorylation of PhaC1 and PhaZa1 can be important for modulation of the activities of PHB synthase and PHB depolymerase. Importance Polyhydroxybutyrate (PHB) and related polyhydroxyalkanoates (PHAs) are important intracellular carbon and energy storage compounds in many prokaryotes. The accumulation of PHB or PHAs increases the fitness of cells during periods of starvation and other stress conditions. The simultaneous presence of poly(3-hydroxybutyrate) (PHB) synthase (PhaC1) and PHB depolymerase (PhaZa1) on synthesized PHB granules in Ralstonia eutropha (alternative designation Cupriavidus necator ) has been previously shown in several laboratories. These findings imply that the activities of PHB synthase and PHB depolymerase should be regulated to avoid a futile cycle of simultaneous synthesis and degradation of PHB. Here, we addressed this question by identifying phosphorylation sites on PhaC1 and PhaZa1 and by site-directed mutagenesis of identified residues. Furthermore, we conducted in vitro and in vivo analysis of PHB synthase activity and PHB contents. Copyright © 2018 American Society for Microbiology.

During 1968, the RA Reactor was operated at nominal power of 6.5 MW for 190 days, and during 50 days at lower power levels. Total production amounted to 31051 MWh which is 3.5% higher than planned. reactor was used for irradiation and experiments according to the demand of 600 users, of which 517 from the Institute and 83 externals users. This report contains detailed data about reactor power and experiments performed in 1968. It is concluded that the reactor operation was more successful than during previous years. There was only one longer interruption which lasted 27 hours because of the power cut on the cable for the pump station on Danube. Number of safety shutdowns were at the same level as during last year. The only significant incident in 1968 was air contamination with the radioactive argon in the reactor hall. The reactor operation was not interrupted although the hall was evacuated for two hours. The was no significant exposure of the staff. In April and September the integral dosed were higher than during other months because of the accident during refueling (mixing the slugs with irradiated and fresh fuel). There was no significant surface contamination, i.e. the decontaminated surface were negligible. Due to 'mixing' refueling scheme.

Contrary to previous years the RA reactor operation plan for 1976 is conditioned by more uncertainties than ever for the following reasons. It is planned for February to repair the components in order to eliminate the consequences of leaking from the vertical experimental channel VK-4 which happened in december 1975. Apart from this, measurements related to transfer of the core to highly enriched fuel under minimum power are foreseen to be performed in February. In April, it would be indispensable to locate the point of He gas leaking and its prevention. Core transfer to highly enriched fuel is planned for April for testing of the fuel elements under operating conditions and step by step increase of the power density up to the nominal power. Complete plan for core transfer would be available by the end of February 1976. It is planned to make-up for the mentioned delays from May-December 1976. [Serbo-Croat] Za razliku od prethodnih godina izrada plana rada reaktora RA za 1976. godinu vezana je za mnogo vise neizvesnosti nego ikada ranije iz sledecih razloga. U februaru se vrsi remont opreme i uklanjanja posledica procurivanja vertikalnog eksperimentalog kanala VK-4, koje se dogodilo decembra 1975. Sem toga u februaru se vrse merenja na minimalnim snagama u sklopu priprema za prelazak na novo gorivo. U aprilu ce biti neophodno lociranje mesta gde istice He gas kao i otklanjanje uzroka ovog curenja. Planirano je da se u aprilu ubaci novo gorivo u jezgro u cilju testiranja pod radnim uslovima uz postepeno povecanje snage do nominalne. Planirano je da se smanjeni obim rada usled navedenih uslova nadoknadi u potpunosti u periodu maj-decembar 1976.

The objective of nuclear reactor kinetics study is to analyze the stability of reactor operation in practice. The obtained parameters should define the needed properties of automatic control system relevant for the stability of the designed reactor system. Refining the analytical models is done by using the analysis and interpretation of experimental data. Results of measured the reactor response obtained by using the reactor oscillator ROB-1 are explained by using the space independent model of the zero power reactor, by power reactor model with one feedback circuit, and by a complex model. It was assumed that the perturbations of the system are small and that linearized kinetic equations could be used. Linearized kinetic equation of the reactor system are transformed into the frequency region in order to analyze the measured values directly. The objective of this paper is to measure the RA reactor kinetics parameters, and analyze the stability of reactor operation at power levels high than nominal. Istrazivanja u oblasti kinetike nuklearnih reaktora imaju za cilj da dovedu analizu stabilnosti rada reaktora na nivo 'radne tehnologije'. Dobijeni pararametri treba da specificiraju potrebne karakteristike sistema automatske kontrole za odgovarajucu stabilnost projektovanog reaktorskog sistema. Doterivanjem analitickih modela do takvog nivoa da se zapazeni fenomeni mogu anailitcki predvideti ide preko analize i interpretacije eksperimentalnih podataka. Eksperimentalni rezultati merenja odziva reaktora, izvedeni reaktorskim oscilatorom ROB-1, interpretirani su na osnovu prostorno nezavisnog modela za reaktor nulte snage, modelom reaktora snage sa jednim kolom povratne sprege, kao i kompleksnim modelom. U ovom radu se poslo od toga da su perturbacije parametara sistema male, pa se mogu upotrebiti linearizovane kineticke jednacine. Linearizovane kineticke jednacine reaktorskog sistema transformirane su u frekventno podrucje s ciljem direktne analize mernih rezultata

Full Text Available There is an ongoing hunt for biologically active compounds that can combat phytopathogenic fungi and improve plant growth without causing any hazards to the environment. Consequently the present study aims at deciphering the plant growth promotion and antifungal capability of Lysinibacillus sphaericus ZA9. The bacterium was previously isolated and identified in our laboratory from maize rhizosphere using 16S rRNA gene sequencing. The test bacterium L. sphaericus ZA9 was found to produce high quantity of IAA (697 μg/ mL; siderophores (195.79 μg/ mL, HCN and hydrolytic enzyme as compared to the reference strain Bacillus sphaericus Z2-7. The bacterium was also capable of solubilizing silicates (Si, phosphates (P, and potassium (K. The bacterium enhanced the seedling vigor and germination of seeds pretreated with it and promoted the shoot length of both cucumber and tomato seeds in greenhouse experiment. L. sphaericus ZA9 and its cell free culture supernatant showed varied antagonistic behavior against Alternaria alternata, Curvularia lunata, Aspergillus sp., Sclerotinia sp., Bipolaris spicifera, Trichophyton sp. Fermentation broth culture of L. sphaericus ZA9 was then used to isolate antifungal metabolites by silica column chromatography. Identification and determination of antifungal compounds was carried out by Thin-layer chromatography (TLC followed by NMR spectroscopy. Two compounds were isolated and identified as 2-pentyl-4-quinolinecarboxylic acid (C15H17NO2 which is a quinoline alkaloid and 1- methylcyclohexene which is a cycloalkene. Compound 1; 2-Penthyl-4-quinolinecarboxylic acid was found to be highly antagonistic against most of the fungi tested as compared to the bacterium itself. Its activity was comparable to that of fungicide Benlate, while compound 2; 1- methylcyclohexene did not show any antifungal activity.

Merenje prelaznih opterećenja na dva modela u aero tunelu t-38 / Measurement of transient loads on two models

Directory of Open Access Journals (Sweden)

Aleksandar Vitić

2008-07-01

Full Text Available Pri ispitivanju modela u "rafalnom" aerotunelu sa prekidnim dejstvom T-38, na Mahovim brojevima većim od 2, moraju se uzeti u obzir prelazne pojave koje se javljaju na početku i na kraju rada aerotunela. To su stanja kada su model i aerovaga izloženi velikim aerodinamičkim silama i momentima. Ova kombinovana opterećenja mogu oštetiti modele i aerovage, pa bi bilo potrebno unapred znati kolike se vrednosti očekuju za pojedine konfiguracije modela, kako bi se izvršio pravilan izbor aerovage i odgovarajućih materijala za izradu modela. U tu svrhu postoje dijagrami koji pružaju mogućnost procene ovih opterećenja. Dijagrami su dobijeni na osnovu ispitivanja nekoliko različitih modela na Mahovim brojevima većim od 2. U radu su prikazana merenja prelaznih opterećenja na još dva modela, a rezultati su upoređeni sa već postojećim dijagramima. / The T-38 wind tunnel is a blow down, intermittent-run type of wind tunnels. During model testing in the this type of wind tunnels, at Mach numbers higher than 2, transient loads which appear during the starting and stopping of the wind tunnel runs must be taken into consideration. These are the conditions when a model and the wind tunnel balance are exposed to large aerodynamic forces and moments. These combined loads can damage models and wind tunnel balances, and, for this reason, it is very important to determine them in advance for any particular model configuration so that an appropriate wind tunnel balance and materials for model manufacturing can be chosen. For that purpose there are graphs which give possibilities to estimate these loads. The graphs are based on experiments with a number of different models at Mach numbers higher than 2. This paper gives the measurements of transient loads on two more models and the results are compared with the already existing graphs.

Activities related to revitalisation of the RA reactor started in 1986, were continued during period 1991-1995. All the planned actions related to renewal of the reactor components were finished. The last, and at the same time most important action, related to exchange of complete reactor instrumentation is underway, delayed. The delivery of components from USSR is late. Production of this instruments is financed by the IAEA according to the contract signed in December 1988 with Russian Atomenergoexport. According to this contract, it has been planned that the RA reactor instrumentation should be delivered to the Vinca Institute by the end of 1990. Only 56% of the instrumentation was delivered until September 1991. Since then any delivery of components to Yugoslavia was stopped because of the temporary embargo imposed by the IAEA. The existing RA reactor instrumentation was dismantled. Control and maintenance of the reactor components was done regularly and efficiently. Fuel inspection by the IAEA safeguards inspectors was done on a monthly basis. There have been on the average 47 employees at the RA reactor which is considered sufficient for maintenance and repair conditions. The problem of financing the reactor activities and maintenance remains unsolved during the period 1991-1995. This research reactor RA Annual is divided into two main parts to cover: (1) operation and maintenance and (2) activities related to radiation protection.

For the sake of reactor, decision about the future operation and financing should be done as soon as possible, either to cease operation or continue with adequate financial support. [Serbo-Croat] Reaktor RA je u 1971. godini radio na nominalnoj snazi 190 dana i 50 dana na manjim snagama. Ukupni rad iznosio je 31606 MWh odnosno 5,3% vise od planiranog, sto je najvisa vrednost od kako je reaktor pusten u rad. Reaktor je koriscen za ozracivanja i eksperimente za 425 korisnika od cega 370 iz Instituta i 55 za korisnika izvan Instituta. Ovaj izvestaj sadrzi detaljne podatke o radu i eksperimentima koji su obavljani. Odstupanja od plana, odnosno veceg ostvarenog rada bilo je u junu i decembru usled posebnih zahteva korisnika. Ukupni broj prekida rada bio je manji od svih prethodnih godina, uglavnom zbog manjeg broja nestanka napona u vreme rada reaktora. U toku godine bilo je samo jedno sigurnosno zaustavljanje, ciji je uzrok bila pojava laznog signala opreme za zastitu reaktora. Nijednog duzeg prekida rada nije bilo zbog neispravnosti opreme. Kracih prekida bilo je usled kidanja spojki na potisnom cevovodu tehnicke vode, sto je bilo izazvano klizanjem zemljista u podrucju crpne stanice na Dunavu. Ukupna doza ozracivanja ljudstva bila je manja nego prethodnih godina. Nije bilo ni jednog akcidenta niti slucaja koji bi se mogao nazvati akcidentom. Dekontaminirano je znatno manje povrsina nego ranijih godina. Zakljuceno je da je uspesan rad reaktora u 1971. godini rezultat valjanog rada u prethodnim godinama. Medjutim usled jos nedefinisane politike u pogledu buduceg rada, odnosno neizvesnosti u vezi finansiranja, neki poslovi su obustavljeni. Tu spada proucavanje mogucnosti prelaska na koriscenje visokoobogacenog goriva sto bi povecalo korisni neutronski fluks i ucinilo reakor konkurentnim za

Nuclear reactor RA at Vinca has been designed as a high flux general purpose research reactor. Among other it was intended to play a role of material testing reactor. A scope of activities of Material Laboratory and Reactor RA Department of Boris Kidric Institute is presented in this report. Reactor RA capacity for reactor structural material and fuel irradiation is also described. The increase of RA reactor irradiation capacity is based on the improvement of VISA type fuel channel for fast neutron irradiations, as well as on the general neutron flux increase, due to introduction of highly enriched uranium fuel into reactor core and the advanced in-core fuel management. The irradiation capacities described allow for the reactor material and fuel testing to the considerable extent. Istrazivacki reaktor RA u Vinci je projektovan kao visokofluksni istrazivacki reaktor opste namene. Pored ostalog, on je namenjen i za testiranje reaktorskih konstrukcionih materijala i goriva. U radu je dat pregled aktivnosti Laboratorije za materijale IBK i reaktora RA na tom podrucju, kao i opis povecanih mogucnosti reaktora RA za ozracivanje reaktorskih materijala i goriva u cilju njihovog testiranja. Povecanje mogucnosti reaktora RA zasniva se na usavrsavanju specijalnog gorivnog kanala tipa VISA (za ozracivanje materijala brzim neutronima), kao i na opstem povecanju neutronskog fluksa na osnovu uvodjenja i nacina koriscenja visokoobogacenog uranskog goriva u reaktoru RA. Opisane mogucnosti reaktora RA dozvoljavaju u znatnoj meri ispitivanje konstrukcionih materijala i goriva energetskih reaktora.

Full Text Available New Gomphotheriidae fossils encouraged the authors to study recently obtained them and review some others materials of this family that were classified in 2000 as Cuvieronius hyodon (Fischer. Together with new tusks remains, the recovery of the anterior portion of the cranial symphysis (alveolar zone of a skull from Taguatagua is remarkable. The morphology of the available tusks and the characteristics of the anterior part of the symphysis allow the assignment of these remains to Stegomastodon. The occurrence of this genus at the end of the Pleistocene in Chile is established. Fossils are compared with others remains from South America and probable dispersal routes through the Andes cordillera are discussed.Nuevos materiales fósiles de Gomphotheriidae obtenidos recientemente, estimularon a los autores a estudiarlos y a revisar algunos otros restos de esta familia, que habían sido asignados, el año 2000, a Cuvieronius hyodon (Fischer. Junto a nuevos restos de defensas, destaca la recuperación de la parte anterior de la sínfisis craneal (zona alveolar de un cráneo de Taguatagua. La morfología de las defensas disponibles y las características de la porción anterior de la sínfisis, permiten asignar estos materiales al género Stegomastodon, fundamentando así la presencia de este género en el Pleistoceno terminal de Chile. Se comparan con otros restos de América del Sur y se discuten las probables vías de migración de estos mamíferos a través de la cordillera de los Andes.

Full Text Available The paper presents the wear characteristics of a hybrid composite based on zinc-aluminium ZA27 alloy, reinforced with silicon-carbide and graphite particles. The tested sample contains 5 vol.% of SiC and 3 vol.% Gr particles. Compocasting technique has been used to prepare the samples. The experiments were performed on a “block-on-disc” tribometer under conditions of dry sliding. The wear volumes of the alloy and the composite were determined by varying the normal loads and sliding speeds. The paper contains the procedure for preparation of sample composites and microstructure of the composite material and the base ZA27 alloy. The wear surface of the composite material was examined using the scanning electronic microscope (SEM and energy dispersive spectrometry (EDS. Conclusions were obtained based on the observed impact of the sliding speed, normal load and sliding distance on tribological behaviour of the observed composite.

Films of alloy ZA27 were produced using electron deposition technique. Structural evolution and phase decomposition of the films were studied. It was found that the alloy films were relatively stable because of a strong preferred crystal orientation of the nano-phases. The dependence of nano-phase stability on the Zn content and the preferred crystal orientation is discussed from point of view of Gibbs free energy

Tim izmjenama iznos općeg (globalnog ograničenja odgovornosti za pomorske tražbine povećan je za 51% u odnosu na iznose iz čl. 3. LLMC 1996 koji se odnose na čl. 6.1(a i 6.1(b, LLMC 1976, dok iznosi iz čl. 7. Konvencije nisu mijenjani. Povećani iznosi primjenjivat će se od 8. lipnja 2015. godine. U radu se analiziraju razlozi koji su doveli do povećanja iznosa općeg (globalnog ograničenja odgovornosti kao i opravdanost ovog povećanja iznosa ograničenja odgovornosti ako se uzme u obzir da je samo u 1,34% slučajeva šteta prelazila sadašnji iznos ograničenja odgovornosti utvrđen u LLMC 1996. Analiziraju se pravne i ekonomske posljedice ovog povećanja iznosa općeg ograničenja odgovornosti te njegov neposredan utjecaj na druge međunarodne konvencije vezane na iznose općeg ograničenja odgovornosti kao što su Bunker konvencija iz 2001. i Međunarodna konvencija o uklanjanju podrtina iz 2007. godine. Upozorava se, međutim, da tendencija koja vodi prema previsokim iznosima ograničenja odgovornosti može izazvati smanjenje interesa država za ratifikacijom LLMC 1996 što će se negativno odraziti na unifikaciju prava u odnosu na ovo pitanje. U radu se stoga razmatraju rješenja koja bi omogućila pravednu naknadu oštećenima i ostvarenje svrhe instituta ograničenja odgovornosti, a ne bi ugrozila unifikacijska nastojanja.

During the previous period RA reactor was not operated because the Committee of Serbian ministry for health and social care has cancelled the operation licence in August 1984. The reason was the non existing emergency cooling system and lack of appropriate filters in the special ventilation system. The new emergency cooling system and the reconstruction of the existing ventilation system were finished in 1989, the conditions for further reactor operation were fulfilled. In the meantime new licensing regulations adopted in 1988 were not demanding the mentioned conditions for reactors operated at power less than 10MW, RA reactor power being 6.5 MW. But the reactor could not be restarted due to planned renewal of the reactor instrumentation. It is planned to exchange the complete instrumentation by the end of 1991. Training program for the staff operating and maintaining the reactor components was prepared in 1985. Reconstruction, modification and construction of components demanded new documentation needed for further safe reactor operation. New version of RA reactor safety report was finished in 1986 according to the recommendations of IAEA and licensing regulations of Yugoslavia. In 1989, new documents were written covering regulations and instructions for reactor operation. The new reactor experimental loop was designed in 1986, and constructed and tested in 1990. All the reactor components were maintained by specific reactor services. Financing of the reactor remains a permanent problem. [Serbo-Croat] U proteklom periodu reaktor RA nije bio u pogonu zato sto je 30. jula 1984. godine Republicki komitet za zdravlje i socijalnu politiku republike Srbije, zabranio njegov rad zbog toga sto reaktor ne poseduje sistem za udesno hladjenje i ne poseduje odgovarajuce filtere u sistemu specijalne ventilacije. Radovi na izgradnji sistema za udesno hladjenje i rekonstrukciji postojeceg sistema specijalne ventilacije zavrseni su 1989. godine. Uslovi za nastavak rada reaktora

zahvat, koji se odnosi na zamenu celokupne instrumentacije je u toku, ali njegova realizacija u 1991. godini kasni zbog zastoja u isporuci opreme koja se izradjuje u Sovjetskom savezu. Izradu ove opreme finansira Medjunarodna agencija za atomsku energiju kroz ugovor sklopljen decembra 1988. godine sa moskovskom firmom Atomenergoexport. Prema tom ugovoru trebalo je da celokupna nova instrumentacija za reaktor RA bude isporucena Institutu u Vinci do kraja 1990. godine, ali je do septembra 1991. godine isporuceno svega 56% od predvidjene kolicine. Od tada je svaka isporuka obustavljena, a razlog je privremena zabrana na sve isporuke opreme za Jugoslaviju izrecena od strane ove organizacije Ujedinjenih nacija. U 1991. godini na reaktoru RA je demontirana postojeca instrumentacija u maksimalno mogucem obimu, kako bi se zadrzala neka osnovna merenja neophodna i u uslovima kada reaktor nije u pogonu. Pri kraju je izrada odredjenih konstrukcionih elemenata za novu instrumentaciju, koju je prihvatio da realizuje Institut u Vinci, kako bi se ubrzala realizacija ovog projekta. Ako sva predvijena oprema ne bude isporucena do kraja marta 1992. godine, nece moci da se otpocne sa probnim radom reaktora u prvoj polovini 1993. godine, kako je planirano. Na realizaciji projekta u 1991. godini ucestvovalo je efektivno 53 radnika, sto je dovoljan broj u uslovima remontnih i investicionih radova. Godisnji izvestaj o radu nuklearnog reaktora RA za 1992. godinu sastoji se od dva dela: prvi deo obuhvata pogon i odzavanje reaktora RA, a drugi poslove zastite od zracenja na reaktoru RA.

Full Text Available Avtorici preučujeta metodo življenjske zgodbe in njeno uporabnost za ugotavljanje izobraževalnih potreb in zanimanj generacij mlajših odraslih in generacij starejših odraslih. Preučujeta njihove generacijske značilnosti, ki se lahko kažejo bodisi v podobnosti bodisi v različnosti članov neke generacije do drugih. Ugotovljene potrebe in zanimanja, utemeljene na generacijskih značilnostih, je mogoče, takšno je spoznanje avtoric, uporabiti kot podlago za oblikovanje vsebine medgeneracijskih izobraževalnih programov. Mladost je čas vstopa v odraslost, čas prevzemanja socialnih vlog odraslih, značilnost današnjih mladih generacij pa je, da v odraslost vstopajo drugače; mladi so prepuščeni individualizmu, močno odvisni od svojega referenčnega okvira, nekatere dejavnosti, nekoč značilne za odrasle, so se premaknile v čas mladosti, druge spet daleč v prihodnost. Anja Šajn in Dušana Findeisen obravnavata tudi značilnosti oseb v poznejših letih življenja, njihovo prehojeno življenjsko pot ter dogodke na tej poti. Na podlagi teorije življenjskega kroga avtorici označita življenje kot potovanje od rojstva do smrti. Osebne izkušnje, kultura, pomembni osebni in družbeni dogodki, način, kako smo izkusili te dogodke, vse to nas posameznike in posamezne generacije naredi drugačne od drugih ljudi in drugih generacij. Medgeneracijsko učenje in izobraževanje lahko prispevata (ni pa nujno, da je tako k medsebojnemu poznavanju in priznavanju generacij in posledično k družbeni trdnosti. Temeljita na potrebah in zanimanjih generacij in lahko krepita vezi med generacijami, kajti družbene vezi se danes rahljajo do takšne mere, da se vse bolj oglaša potreba celo po novi družbeni pogodbi. Primarni cilj medgeneracijskega učenja ni učenje o neki temi, nekem vprašanju, je predvsem učenje o odnosih – sredi odnosov – in je učenje za skupnost, skupnost generacij, ugotavljata avtorici.

Pritom se posebna pažnja posvećuje brojnim novim subjektima, institutima, dokumentima, te rješenjima koja se u Konvenciji zauzimaju, uvijek uz nastojanje da izlaganja budu potkrijepljena, ili pak kritički sagledana, u svjetlu do sada usvojenih rješenja pravne teorije, te poslovne i sudske prakse. Autor u zaključku iznosi i sučeljava oprečne stavove koji se u literaturi iznose, zauzima svoj stav prema njima i rješenjima sadržanima u Konvenciji, te razmatra moguća rješenja de lege ferenda za donošenje jednog prihvatljivog i racionalnog pravnog sistema odgovornosti za robu u prijevozu (pomorskom i multimodalnom na međunarodnom planu.

Atenica: u potrazi za izgubljenim spalištem

Full Text Available Funerarni konteksti svakako su arheološki zapisi u čijem formiranju značajnu ulogu igraju simboličke i kultne predstave zajednice. S druge strane, u odsustvu pisanih svedočanstava o tim predstavama, arheolozi su skloni da svoje interpretacije zasnivaju na uopštenim i pojednostavljenim idejama o „primitivnim” kultovima, kao što je „solarni kult”. U takvom postupku, tehnički aspekti zapisa zanemaruju se u korist tumačenja pretpostavljenih simboličkih „poruka”. Među kneževskim grobovima centralnog Balkana, humke u Atenici pored Čačka dugo su predstavljale jedini primer ove vrste sahrane koji je istražen u okviru sistematskih arheoloških istraživanja i stoga je čitav niz autora posvećivao posebnu pažnju konstrukciji ovih tumula i mogućnostima interpretacije rituala koji je pratio polaganje pokojnika. U ovom pogledu, naročito je značajna tzv. „ritualna površina” u okviru humke II – tri pravougaona prostora oivičena redovima oblutaka, sa pravilno raspoređenim levkastim jamama, ispunjenim tamnom zemljom, fragmentima keramike i gorelih kostiju. Interpretacije su se kretale od ideja o grobovima kremiranih ljudskih žrtava, preko replika svetilišta, sve do složene simbolike solarnog kulta, izražene numerološkim pravilnostima. S druge strane, budući da se radi o kremiranim pokojnicima, u okviru obe humke identifikovana su spališta – relativno male lučne konstrukcije od redova oblutaka, na kojima su takođe zapaženi tragovi gorenja. Niz praktičnih nelogičnosti koje proističu iz ovih tumačenja ostao je po strani, u nastojanju da se složeni ritual sahrane sa kremacijom poveže sa simboličkim predstavama percipiranim kao primerene za kulturni kontekst sahrana u Atenici – ljudske žrtve, solarni kult. U kružnom dokaznom postupku, ove su ideje, manje ili više prećutno, uzimane za početnu premisu šire interpretacije kultnih praksi zajednice koja je svoje istaknute članove sahranila pod humkama u

years of operation as well as purification of heavy water. [Serbo-Croat] Reaktor RA je u 1969. godini radio na nominalnoj snazi 200 dana i 15 dana na manjim snagama. Ukupni rad iznosio je 31131 MWh odnosno 3.77% vise od planiranog. Reaktor je koriscen za ozracivanja i eksperimenta prema zahtevima 463 korisnika iz Instituta i 63 izvan Instituta. Ovaj izvestak sadrzi detaljne podatke o snazi na kojoj je reaktor radio tokom 1969. godine i o uradjenim eksperimentima. Zakljuceno je da je reaktor RA uspesno radio prema planu rada. Da nije bilo problema sa napajanjem elektricnom energijom tokom poslednja tri meseca i niskog vodostaja Dunava u septembru i oktobru protekle godine bila bi to najuspesnija godina od pustanja reaktora u pogon. Broj sigurnosnih zaustavljanja nije bio veci u odnosu na prethodne dve godine i pored poteskoca u poslednjem kvartalu. Osoblje je bilo izlozeno povecanim dozama zracenja usled tri incidenta. Jedan je bio raspadanje kenera sa srebrom (zbog duzeg stajanja u aktivnoj zoni), sto je uzrokovalo kontaminaciju radne platforme, tako da je fon porastao za 10 do 100 puta od normalnohg Druga dva slucaja su bila otkazivanje uredjaja za mesanje goriva u tehnoloskim kanalima. Zamena goriva je radjena cetiri puta u toku godine, utroseno je 499 svezih gorivnih elemenata. Primenjena je metoda mesanja svezih gorivnih elemenata sa koriscenim gorivnim elementima u gorivnom kanalu. Dekontaminacija povrsina bila je na nivou prethodnih godina i pored problema sa srebrom. Kako su sa reaktora tokom godine otisla dva saradnika sa visokom spremom broj ljudi je opao na neophodan minimum za pogon i odrzavanje reaktora. Navrsavajuci u ovoj godini deset godina rada moze se reci da su rad i stanje opreme na tehnicki solidnom nivou. Kako bi se posle deset godina rada izvrsila kontrola vaznih komponenti reaktora i obavila rekoncentracija teske vode, za 1970. godinu je planirano da se proizvodnja smanji na 25000 MWh, a baziran je na istim principima kao i planovi za prethodne

Independent CO{sub 2} loop was designed for cooling the samples irradiated in the vertical experimental channels in the region of heavy water or in the graphite reflector. It is considered as a significant improvement of the RA reactor experimental possibilities. Six 'heads' are placed in vertical experimental channels and connected in parallel with the outer loop which contains out-of-reactor equipment. It is planned to irradiate samples in the 'heads' of the loop for the needs of Hot laboratory and Laboratory for reactor materials. Heat generated during sample irradiation is removed by CO{sub 2} circulation. This report contains detailed description of the main loop, auxiliary systems, calculation results of anti reactivity and activation of construction materials of the low-temperature CO{sub 2} loop. A separate chapter is devoted to control and regulation of temperature and pressure. Testing of the fundamental parameters of the coolant loop showed that it could fulfill more demanding tasks than designed by the project. Annex of this report includes results of leak testing for the loop 'heads' in vertical experimental channels VEK-6 and VEK-8 by helium leak detector. [Serbo-Croat] Nezavisno kolo CO{sub 2} namenjeno je za hladjenje uzoraka ozracivanih u VEK reaktora u zoni teske vode i u zoni grafita, i predstavlja znacajan doprinos povecanju eksperimentalnih mogucnosti reaktora RA. Sest 'glava' je postavljeno u vertikalne eksperimentalne kanale i paralelno vezano na spoljno kolo koje sadrzi vanreaktorsku opremu. U glavama petlje se predvidja ozracivanje raznovrsnih uzoraka materijala za potrebe Laboratorije za visoku aktivnost i Laboratorije za reaktorske materijale. Toplota koja se generise prilikom ozracivanja uzoraka odvodi se cirkulacijom CO{sub 2}.

Activities related to revitalisation of the RA reactor started in 1986, were continued in 1996. All the planned actions related to renewal of the reactor components were finished. The last, and at the same time most important action, related to exchange of complete reactor instrumentation is underway, delayed. The delivery of components from USSR is late. Production of this instruments is financed by the IAEA according to the contract signed in December 1988 with Russian Atomenergoexport. According to this contract, it has been planned that the RA reactor instrumentation should be delivered to the Vinca Institute by the end of 1990. Only 80% of the instrumentation was delivered until September 1991. Since then any delivery of components to Yugoslavia was stopped because of the temporary embargo imposed by the IAEA. The existing RA reactor instrumentation was dismantled. Control and maintenance of the reactor components was done regularly and efficiently. Fuel inspection by the IAEA safeguards inspectors was done on a monthly basis. There have been on the average 43 employees at the RA reactor which is considered sufficient for maintenance and repair conditions. The problem of financing the reactor activities and maintenance remains unsolved. Research reactor RA Annual report for year 1996 is divided into two main parts to cover: (1) operation and maintenance and (2) activities related to radiation protection. [Serbo-Croat] U toku 1996. godine nastavljeni su poslovi na revitalizaciji reaktora RA, zapocetoj 1986. godine. Okoncan je niz zahvata na opremi postrojenja kojima ce se u narednom periodu omoguciti kontinualan i pouzdan rad ovog reaktora. Poslednji, i ujedno najveci zahvat, koji se odnosi na zamenu celokupne instrumentacije kasni zbog zastoja u isporuci opreme koja se izradjuje u Sovjetskom savezu. Izradu ove opreme finansira Medjunarodna agencija za atomsku energiju kroz ugovor sklopljen decembra 1988. godine sa moskovskom firmom Atomenergoexport. Prema tom

Davanje ovlasti općinama i gradovima za redovito upravljanje pomorskim dobrom imalo je svoju dobru namjeru, ali u stvarnosti se ipak pokazalo da se od strane općina i gradova u okviru njihovih ovlasti ne upravlja kvalitetno i ne vodi dovoljno brige o pomorskom dobru. Učestale su pojave nekontroliranoga nasipanja građevinskog i drugih otpadnih materijala uz samu obalu, odnosno u more, uz privolu predstavnika lokalne samouprave, a često i u njihovoj režiji bez odgovarajućih akata za takovu gradnju. Smatramo da je potrebno potpunije urediti ovo pitanje i to tako da se detaljnije odredi konkretni sadržaj djelatnosti koje se mogu odobriti na pomorskom dobru na razini gradova/općina, ali da ih se uvjetuje zadovoljavanjem posebnih uvjeta, koji su predviđeni, primjerice, dokumentima prostornog uređenja te uvjeta koje određuju mjerodavna javnopravna tijela. Premda se na različite načine pristupa problemu izvanrednog upravljanja pomorskim dobrom, smatramo da je potrebno doraditi sadašnje zakonsko određenje izvanrednoga upravljanja pomorskim dobrom na način da se u njega uključi i sanacija pomorskog dobra, koja je nužna zbog neodgovarajućeg održavanja pomorskog dobra izvan luka. Za davatelja koncesije prema važećim propisima nejasno su određeni kriteriji kojima se mora rukovoditi kod davanja koncesije u svrhu gospodarskog korištenja pomorskog dobra kada se druge osobe djelomično ili u potpunosti isključuju iz upotrebe i iz korištenja pomorskog dobra pa je potrebno o tome voditi računa prilikom budućih izmjena tih propisa.

Full Text Available U skladu sa sve strožim zahtevima za očuvanje životne sredine i većom bezbednošću, tendencije u razvoju suvremenih ubojnih sredstava (UbS, pored povećanja pouzdanosti i efikasnosti, usmerene su i na povećanje sigurnosti pri njihovoj proizvodnji, skladištenju, manipulaciji i upotrebi. Na taj način dobijena je nova kategorija UbS, tzv. neosetljiva UbS, kod kojih je verovatnoća neželjenog aktiviranja pod dejstvom spoljnih impulsa svedena na minimum. Suština rešavanja ovog problema je primena eksplozivnih materija koje su mnogo manje osetljive na spoljne uticaje u odnosu na standardne. Osnovni zahtev koji se pri tome postavlja je da taktičko-tehničke karakteristike ostanu na nivou ili budu bolje u odnosu na postojeća UbS. U radu je ukratko objašnjen koncept razvoja neosetljivih UbS i dat pregled najznačajnijih rezultata istraživanja u oblasti eksplozivnih materija koje zadovoljavaju zahteve za primenu u neosetljivim UbS. / According to severe environment protection and safety requirements, tendencies in development of modern munitions, besides of increasing reliability and efficiency, are directed to decreasing of danger during their processing, storing, handling and operating. In that manner the new category of munitions has been obtained, named insensitive munitions, with a minimum probability of unplanned activating. The best method for solving this problem is using of explosive substances that are more insensitive according to standard ones. The main requirement is the tactical and technical characteristics stay at the level or to be better according to the existing munitions. In this paper the developing concept of insensitive munitions is shortly explained and presented a review of most important research results of explosive materials that fulfill requirements for applying in insensitive munitions.

Devices for sample irradiation in the vertical RA reactor channels will be made of aluminium alloys. According to the regulations concerned with introducing materials into the RA reactor core, corrosion characterisation of these materials is an obligation. Corrosion properties of four aluminium alloys were investigated both in contact with stainless steel and without it. First part of this report deals with the corrosion testing of aluminium alloys in water by gravimetric and electrochemical methods. Bi-distilled water at temperatures less than 100 deg C was used. Second part is related to aluminium alloys corrosion in carbon dioxide gas under experimental conditions. The second part of research was initiated by the design of the head of the independent CO{sub 2} loop for samples cooling. [Serbo-Croat] Uredjaji za ozracivanje u vertikalnim kanalima reaktora RA, bice napravljeni od legura aluminjuma. Prema propisima o unosenju materijala u RA reaktor materijali se moraju prethodno ispitati i sa stanovista korozije.

Preparation of the experiment with highly enriched fuel was based on the experience gained in constructing the capsule for natural uranium fuel. The possibility of using capsules with enriched UO{sub 2} in the RA reactor was analyzed. Special attention was devoted to the analysis of heat removal from the fuel rods. Capsule for irradiation of enriched UO{sub 2} was designed. The most important change appeared in sealing zircaloy-2 with stainless steel part. This must be done by diffusion welding. Since there is no device for diffusion welding in our country the elements will be sent to Saclay, France. All the parts made of domestic material were fabricated in the Institute. Purchase of elements that must be imported is delayed due to procedures for obtaining foreign currency. The fabrication of the capsule can be completed within 25 days upon obtaining the mentioned material from abroad. This report contains the safety report for the experiment with the enriched fuel. Na osnovu dosadasnjeg rada i iskustva na izgradnji kapsula za neobogaceno gorivo izvrsena je priprema za eksperimenat sa obogacenim gorivom. Analizirana je mogucnost koriscenja kapsula sa obogadenim UO{sub 2} u reaktoru RA. Narocito je posvecena paznja analizi odvodjenja generisane toplote iz sipki gorivnih elemenata. Projektovana je kapsula za ozracivanje obogacenog UO{sub 2}. Najznacajnija izmena je kod spajanja dela od cirkaloja-2 sa delom od nerdjajuceg celika. To spajanje morace se izvrsiti na masini za difuziono zavarivanje. Kako takvu masinu nemamo u zemlji elemente cemo dati da se zavare u Saclay-u. Svi delovi za koje nije bio potreban uvozni materijal izradjeni su u nasem Institutu. Kapsula nije montirana jer materijal iz uvoza koji se ugradjuje u kapsulu nije jos stigao u zemlju. Nabavka uvoznlh elemenata nije izvrsena na vreme zbog zakasnjenja kod odobravanja deviznih sredstava. Potpuna montaza kapsule moze se obaviti 25 dana po dobijanju pomenutog materijala.

Full Text Available Dans ses deux premiers films, Rabah Ameur-Zaïmeche interprète un personnage qui, ayant écopé de la « double peine », finit par perdre sa place dans un aller et retour sans issue, entre son village algérien d’origine qui le rejette (Bled number One et la France qui l’expulse puis le traque à son retour (Wesh wesh qu’est-ce qui se passe ?. À ce destin qui s’avère borné par la folie, d’un côté de la Méditerranée, ou par la mort de l’autre, le cinéaste oppose la créativité de ses propres collectifs de production, dont il laisse volontairement des traces dans chacun de ses films. Il entend ainsi, malgré tout, réinvestir, par le désir de groupe, le champ du politique, et par l’invention de formes cinématographiques, ne pas exclure le spectateur d’un sentiment de solidarité et de fraternité désancré de ses bases strictement communautaires. Adossé à la réalité vécue par une génération issue de l’immigration algérienne, née ou ayant grandi en France après l’indépendance de l’Algérie, le cinéma de Rabah Ameur-Zaimèche évoque les ambivalences de l’expérience groupale de ceux qui vont et viennent avec constance et intensité d’une rive à l’autre de leurs désirs d’appartenance et d’engagement.  In his two first movies, Rabah Ameur-Zaïmeche plays a character who, subject to legal “double jeopardy”, finds himself lost in an inescapable back and forth between his native Algerian village, which rejects him, (Bled number One and France, which expels him and then, upon his return, hunts him down (Wesh wesh qu’est-ce qui se passe ?. Against this fate, which ends in madness on one side of the Mediterranean or death on the other, Rabah Ameur-Zaïmeche sets the creativity of his production teams, traces of whose work remains in each of his films. Despite everything, the filmmaker looks to reinvest the political field with collective desire, and, through the use of inventive cinematic

The ten-year work on in-pile chemical dosimetry of the Radiation chemistry Department at the Boris Kidric Institute at Vinca is reviewed. As an introduction, the general theory of the dosimetry of two-component radiation field is given and the uses of the derived equations in calorimetry and chemical dosimetry have been discussed. The chemical systems worked out for the in-pile use: solid oxalic acid and their solutions in light and heavy water, are then described and also the procedures of their use. The latter two are treated as a double system particularly suitable for two-component radiation fields. Finally, the limitations in use are discussed and some other systems, the study of which is in progress, mentioned (malonic and succinic acid) (author) [Serbo-Croat] Merenje energije koju apsorbuje sistem izlozen zracenju sastavni je deo svakog radijaciono-hemijskog eksperimenta. Time se moze objasniti veliki interes za koriscenje postojecih i razvijanje novih metoda dozimetrije u laboratorijama koje se bave radijacionom hemijom. Poslednjih godina posebna paznja se posvecuje dozimetriji vrlo visokih doza (10{sup 2}-10{sup 3} mrad) narocito onih sa kojima se radi u polju mesovitog zracenja reaktora. U laboratoriji za radijacionu hemiju Instituta 'Boris Kidric' u Vinci na dozimetriji zracenja reaktorskog jezgra radi se vec skoro 10 godina. Ta aktivnost je deo rada na hemijskoj dozimetriji uopste, kojom se bavi ova laboratorija od svog postanka (kraj 1955. godine). Sa radom na dozimetriji kod nas otpocelo se u periodu prvog podizanja na snagu reaktora RA, krajem 1959. godine. Paralelno su razvijane i primenjivane i hemijske i kalorimetrijske metode i njima vrsena dozimetrijska kalibracija reaktora.

As an oxygen-containing ligature, we used the electrodes-satellite from the reaction mass residues mixture from the retort lid for magnesium thermal reduction of a titanium sponge, a specially prepared gaseous argon oxygen mixture containing 30% oxygen applied directly to the melting space, microsize (10-15 mm powder particles of titanium oxide and titanium oxide nanopowder with a particle size of 21 ± 5 nm. The structure and the properties of titanium alloyed by oxygen from the oxygen-containing ligature, gas phase and titanium oxide powder during chamber electroslag remelting of the titanium sponge are investigated. It was found that at the oxygen content of 0.053%mas. to 0.22%mas. in the metal formed a homogeneous single-phase structure typical for commercial titanium formed by polyhedral grains of the α-phase. The increase of the oxygen concentration in titanium for more than 0.22%mas. leads to the formation of the microstructure with a typical needle structure, which allows it to be classified as the α ׳-phase. / U radu su prikazani rezultati legiranja titanijuma kiseonikom u procesu elektropretapanja pod troskom u peći.

Vojnici vozači su selekcionirana grupa vozača, pa se smatra daje njihovo vreme reagovanja kraće od vremena reagovanja generalne populacije vozača i od normativnog vremena reagovanja, koje se koristi u analizama. Zbog toga je izvršeno merenje vremena reagovanja vojnika vozača kočenjem, s ciljem da se sagleda njegov uticaj na bezbednost saobraćaja i na upravljanje saobraćajnim tokovima, kao i da se stručna javnost upozna sa dobijenim rezultatima. U radu su prikazani rezultati merenja vremena reagovanja vojnika vozača kočenjem, za slučajno odabranu grupu, u realnim uslovima. / Safety in military traffic and its management depends on the reaction time of military drivers. Military drivers are a selected group of soldiers, so it is considered that their reaction time is shorter than the reaction time of general drivers population and it is also shorter than the normative reaction time, which is used in the analyses. Therefore, the stopping time of military drivers was tested, in aider to see the influence on traffic safety and management of traffic courses, and to interest the professionals in the given results. In the essay results of stopping time in the real conditions for a random chosen group of military drivers are shown.

A relative measurement of total cross-sections is reported for polyethylene, marble, iron, and lead targets for the inclusive charged-current reaction nu_mu + N -> mu^- + X. The targets, passive blocks of ~100kg each, were exposed simultaneously to the CERN SPS wide-band muon-neutrino beam over a period of 18 weeks. Systematics effects due to differences in the neutrino flux and detector efficiency for the different target locations were minimised by changing the position of the four targets on their support about every two weeks. The relative neutrino fluxes on the targets were monitored within the same experiment using charged-current interactions in the calorimeter positioned directly downstream of the four targets. From a fit to the Z/A dependence of the total cross-sections a value is deduced for the effective neutron-to-proton cross-section ratio.

Practical silicon Light emitting devices fabricated by standard IC technology

2004-01-01

Full Text:Research activities are described with regard to the development of a comprehensive approach for the practical realization of single crystal Silicon Light Emitting Devices (Si-LEDs). Several interesting suggestions for the fabrication of such devices were made in the literature but they were not adopted by the semiconductor industry because they involve non-standard fabrication schemes, requiring special production lines. Our work presents an alternative approach, proposed and realized in practice by us, permitting the fabrication of Si-LEDs using the standard conventional fully industrialized IC technology ''as is'' without any adaptation. It enables their fabrication in the same production lines of the presently existing IC industry. This means that Si-LEDs can now be fabricated simultaneously with other components, such as transistors, on the same silicon chip, using the same masks and processing procedures. The result is that the yield, reliability, and price of the above Si-LEDs are the same as the other Si devices integrated on the same chip. In this work some structural details of several practical Si-LED's designed by us, as well as experimental results describing their performance are presented. These Si-LED's were fabricated to our specifications utilizing standard CMOS/BiCMOS technology, a fact which comprises an achievement by itself. The structure of the Si-LED's, is designed according to specifications such as the required operating voltage, overall light output intensity, its dependence(linear, or non-linear) on the input signal (voltage or current), light generations location (bulk, or near-surface), the emission pattern and uniformity. Such structural design present a problem since the designer can not use any structural parameters (such as doping levels and junction depths for example) but only those which already exist in the production lines. Since the fabrication procedures in these lines are originally designed for processing of

Full text: This activity is a logical continuation of the experiment at the RA reactor during 1962 which was based on compensating the effect by means of control rod. Since results are given with significant errors, new method for measuring the absorption cross sections via reactor period. Experiment was done at the RB reactor which was particularly prepared for this type of experiments. Reactor power was from 50 mW to 2 W. Absorption cross sections were measured for two types of material: domestic graphite No.3 and French graphite 'Pachiney', and two types of aluminium. Total errors in applying this method are {+-} 5%, where the source of major part of error comes from uncertainty of the standard absorption power (previous method gave {+-} 10 do 55% ). Comparison of French graphite absorption cross section obtained via reactor period and via control rod showed approximate agreement with discrepancy of 5.4% which is considered within the precision of this method. Considering the accuracy of measurement results and reactor economy it is concluded that measuring absorption cross sections of samples via period of RB reactor is more favourable than measurements by control rod at the RA reactor.

Measurement of the Z/A dependence of neutrino charged-current total cross-sections

CERN Document Server

Kayis-Topasku, A; Dantzig, R V

2003-01-01

A relative measurement of total cross-sections is reported for polyethylene, marble, iron, and lead targets for the inclusive charged-current reaction nu submu + N -> mu sup - + X. The targets, passive blocks of propor to 100 kg each, were exposed simultaneously to the CERN SPS wide-band muon-neutrino beam over a period of 18 weeks. Systematic effects due to differences in the neutrino flux and detector efficiency for the different target locations were minimised by changing the position of the four targets on their support about every two weeks. The relative neutrino fluxes on the targets were monitored within the same experiment using charged-current interactions in the calorimeter positioned directly downstream of the four targets. From a fit to the Z/A dependence of the total cross-sections a value is deduced for the effective neutron-to-proton cross-section ratio. (orig.)

In the RA reactor action plan for 1977 it is foreseen that the reactor would be operated for 181 days, mostly at nominal power of 6.5 MW. It is planned to produce 28236 MWh in total. Five reactor core exchanges (refuelling) are planned. The plan includes time for repair of components as well as for cooling. [Serbo-Croat] Plan rada reaktora RA predvidja rad tokom 181 dana, vecim delom na nominalnoj snazi od 6,5 MW tokom 1977. godine. Planirano je da ukupni rad iznosi 28236 MWh. Planom je predvidjeno i pet izmena goriva kao i vreme potrebno za remont opreme i hladjenje.

During 1980. the RA reactor was not in operation. That is why this period was devoted to definition of operating conditions for further reactor operation with 80% enriched fuel. The fuel elements which were in the core at the moment of shutdown in March 1979will not be used again (388 80% enriched fuel elements, and 511 2% enriched fuel elements). The reactor will be operated only with 80% enriched fuel, staring with initiat core configuration with 440 elements on the borders gradually changing to equi;librium core with 720 fuel elements. The analyses were concerned with safety issues of future operation. [Serbo-Croat] Reaktor RA tokom 1980 godine nije radio. Zbog toga je ovaj period iskoriscen za intenzivan rad na definisanju pogonskih uslova za dalji rad reaktora sa 80% obogacenim gorivom. Gorivo sa kojim je reaktor prestao da radi marta 1979. godine (388 gorivnih elemenata 80% obogacenoh i 511 elementa 2% obogaceno) nece biti vraceno u jezgro, vec ce reaktor raditi samo sa 80% obogacenim gorivom, pocev od konfiguracije sa 440 elemenata na periferiji do ravnotezne konfiguracije sa 720 elemenata. Sve nalize su se bavile sigurnosnim aspektima rada reaktora sa visokoobogacenim gorivom u jezgru.

the pool. Refuelling was done three times by 'mixing' the irradiated fuel slugs with 5 to 6 fresh ones. Total exposure of the staff was increased due to activities during the shut-down period. Individual maximum exposure dose was not higher than 3.5 R. Cooperation with the French partner, concerned with the possibility of using 93% enriched fuel instead of the present low enriched, was continued. This would enable achievement of higher neutron flux, order of magnitude of 10{sup 14} n/cm{sup 2} sec. It is mentioned that there is doubt whether the plan for 1971 could be fulfilled for financial difficulties. [Serbo-Croat] Reaktor RA je u 1970. godini radio na nominalnoj snazi 160 dana i 40 dana na manjim snagama. Ukupni rad iznosio je 25968 MWh odnosno 3.87% vise od planiranog. Plan rada razlikovao se od prethodnih godina zbog slanja teske vode na rekoncentraciju u Francusku. Izotopski sastav teske vode je opao na 99.05% a posle rekoncentracije iznosi 99,96%. Odstupanje od plana rada u septembru mesecu bilo je izazvano kasnjenjem prispeca teske vode usled administrativnih teskoca i transporta. Pocetak kampanje odlozen je i zbog posledica ostecenja kosuljice jednog gorivnog elementa, sto se dogodilo odmah po pocetku rada pa je reaktor bio zaustavljen. U oktobru i novembru reaktor je radio 28 odnosno 25 dana respektivno sto je omogucilo da se nadoknadi izgubljeno vreme. Reaktor je koriscen za ozracivanja i eksperimente za 390 korisnika od cega 340 iz Instituta i 50 za korisnika izvan Instituta. Ovaj izvestaj sadrzi detaljne podatke o radu i eksperimentima koji su obavljani. Zakljucuje se da je reaktor radio uspesno prema planu rada. Kracih zastoja u radu bilo je samo zbog teskoca sa cevovodima tehnicke vode kao posledica klizanja zemljista. Reaktor je samo dva puta sigurnosno zaustavljan zbog neispravnosti opreme odnosno laznog signala elektronske aparature sistema upravljanja. Vreme dok reaktor nije radio iskorisceno je za inspekciju unutrasnjosti reaktorskog suda. Pomocu

W Unii Europejskiej z powodu raka gruczołu krokowego umiera każdego roku ponad 85 000 mężczyzn. Dotyka on często mężczyzn w sile wieku, a długi i złożony proces jego leczenia negatywnie wpływa na efektywność i stabilność życiową. W początkowym stadium choroba przebiega często bezobjawowo, co powoduje, że mężczyźni nie są świadomi zagrożenia i nie podejmują czynności profilaktyczno-leczniczych. Uwzględniając wymienione zagrożenia, celowe jest podjęcie działań zmierzających do uruchomienia systemu profilaktyki, leczenia i monitorowania chorych z rakiem gruczołu krokowego, co będzie stanowić gwarancję utrzymania wymaganego poziomu stanu zdrowia.

The stabilizing effect of an axial flow on the m = 1 kink instability in Z pinches has been studied numerically with a linearized ideal MHD model to reveal that a sheared axial flow stabilizes the kink mode when the shear exceeds a threshold. The sheared flow stabilizing effect is investigated with the flow-through Z pinch experiment, ZaP. An azimuthal array of surface mounted magnetic probes located at the midplane of the 50 cm long pinch plasma measures the fluctuation levels of the azimuthal modes m=1, 2, and 3. After pinch formation a quiescent period is found where the mode activity is reduced to a few percent of the average field. Optical images from a fast framing camera and a HeNe interferometer also indicate a stable pinch plasma during this time. Doppler shift measurements of a C-III line correspond to an axial flow velocity of 9.6x10 4 m/s internal to the pinch. During the time when the axial plasma flow is high, the plasma experiences a quiescent period which lasts approximately 800 exponential growth times predicted by linear theory for a static plasma.

Entre la multitud de promociones que empezaron a transformar el litoral mediterráneo, Ciudad Blanca proyectada por Sáenz de Oíza en la Bahía de Alcudia, aunque no concluida por completo, ejemplifica cómo un encargo especulativo para acoger a una gran masa de veraneantes, puede aprovechar la euforia del momento, ensayando un modelo residencial ideal, en un contexto próximo a los debates de arquitectura que se estaban dando en el resto de Europa, abordados por los arquitectos de la “Tercera Generación”, que pretendían la superación de los dogmatismos del Movimiento Moderno. La lección que el Oíza profesor nos lega a través de esta experiencia, aparte del modo de proceder, enfrentándose con cierta dosis experimental cual alumno afrontando un ejercicio académico innovador, reside en el valor didáctico de mostrar mediante una serie de mecanismos proyectuales, la vital atención prestada al paisaje y al habitante, a la exterioridad y a la interioridad de la obra, desarrollando una empatía entre el lugar y el momento, que generó un mestizaje interesante entre nuevos conceptos de agrupación, ejecutados con sistemas estructurales racionalistas en los que se introducen elementos puntuales prefabricados, combinando tradición y novedad.

Zahvaljujuci iskustvu stecenom prilikom prvog i do sada jedinog prskanja kosuljice gorivnog elementa, pre oko devet godina, moglo se sa visokim stepenom sigurnosti tvrditi da do toga nije doslo. Da je doslo do isticanja fisionih produkata znacajno bi se povecali nivoi zracenja na karakteristicnim tackama reaktorskih sistema, i u radnoj sredini povecao bi se i relativni sadrzaj fisionih produkata u rashadnom mediju, moguce bi bilo registrovati sveze fisione produkte kao sto je {sup 131} I, u vecim kolicinama.

RA reactor was not operated during 1993 because of the complete instrumentation exchange. Although it has been planned to exchange the complete instrumentation until the end of 1993, and to start reactor operation in the first half of 1993 this was not fulfilled because the instrumentation was not delivered until the end of 1993. Main activities during past seven years were related to construction of the emergency cooling system; repair and reconstruction of the system for handling the spent fuel and improvement of spent fuel storage conditions; exchange of the aged instrumentation. Other reactor components and systems, reactor core, primary coolant loop and gas circulation system are in good condition concerning future start-up. [Serbo-Croat] U 1993. godini reaktor nije bio u pogonu zbog zamene njegove celokupne instrumentacije. Iako je bilo planirano da se celokupna instrumentacija zameni do kraja 1993. te da reaktor pocne sa radom u prvoj polovini 1993. Ovo nije ispunjeno jer celokupna oprema nije isporucena ni do kraja 1993. godine. Osnovni zahvati koji su u proteklih sedma godina izvrseni, odnosili su se na izgradnju sistema za udesno hladjenje, rekonstrukciju sistema za rukovanje ozracenim gorivom i poboljsanje uslova za stokiranje ovog goriva, zamenu instrumentacije. Ostali sistemi reaktora, reaktorsko jezgro, primarno kolo hladjenja i sistem za cirkulaciju gasa su u dobrom stanju i mogu se nesmetano koristiti u buducem radu.

pouzdan rad ovog reaktora. Poslednji, i ujedno najveci zahvat, koji se odnosi na zamenu celokupne instrumentacije je u toku, ali njegova realizacija u 1994. godini kasni zbog zastoja u isporuci opreme koja se izradjuje u Sovjetskom savezu. Izradu ove opreme finansira Medjunarodna agencija za atomsku energiju kroz ugovor sklopljen decembra 1988. godine sa moskovskom firmom Atomenergoexport. Prema tom ugovoru trebalo je da celokupna nova instrumentacija za reaktor RA bude isporucena Institutu u Vinci do kraja 1990. godine, ali je do septembra 1991. godine isporuceno svega 56% od predvidjene kolicine. Od tada je svaka isporuka obustavljena, a razlog je privremena zabrana na sve isporuke opreme za Jugoslaviju izrecena od strane ove organizacije Ujedinjenih nacija. U 1991. godini na reaktoru RA je demontirana postojeca instrumentacija u maksimalno mogucem obimu, kako bi se zadrzala neka osnovna merenja neophodna i u uslovima kada reaktor nije u pogonu. U 1994. godini nastavljen je rad na razradi i dopuni sovjetskog projekta. Kontrola i odrzavanje celopkupne opreme postrojenja, kao i remontni radovi izvrsavani su redovno i efikasno. Veoma obiman remont sekundarnog kola hladjenja reaktora privodi se kraju i bice okoncan u prvoj polovini 1995. a u skladu postojecim zakonskim propisima i sa preporukama MAAE. Kontrola goriva od strane inspektora MAAE obavljana je jedanput mesecno. Na reaktoru RA u 1994. godini radilo je prosecno 47 radnika, sto je dovoljan broj u uslovima remontnih i investicionih radova.

Full Text Available The Aurora Stratum of the TD6 level of the Pleistocene site of Gran Dolina (Trinchera del Ferrocarril, Sierra de Atapuerca, Burgos, Spain have yielded more than one hundred human fossil remains, of the species Homo antecessor and belonging to a minimum (MNI of nine individuals. In this paper we made the MNI determination and the age at death of the individuals, using data observed in the mandibular, maxillary, and dental remains. The previous taphonomic analysis concluded that the origin of the hominin accumulation was due to a punctual or recurrent episode of «gastronomic» cannibalism. Our analysis revealed that most individuals (N = 7 are immature between three and thirteen, whereas two are young adults between fifteen and eighteen. Considering this peculiar mortality distribution, alternative hypotheses on the possible scenarios in which hominins were apprehended, as well as the implications for the human behaviour in the Pleistocene are discussed.En el Estrato Aurora del nivel TD6 del yacimiento pleistoceno de Gran Dolina (Trinchera del Ferrocarril, Sierra de Atapuerca, Burgos se han obtenido más de cien restos fósiles de homininos de la especie Homo antecessor, que pertenecen a un mínimo (NMI de nueve individuos. En este trabajo realizamos la determinación del NMI y de la edad de muerte de los individuos, empleando datos observados en los restos de mandíbula, maxilar y dientes. El análisis tafonómico previo concluyó que el origen de la acumulación de los restos de homininos fue un acto puntual o recurrente de canibalismo de tipo «gastronómico ». Nuestro análisis revela que la mayor parte de los individuos (n = 7 son inmaduros, de entre tres y trece años, mientras que dos son adultos jóvenes, de entre quince y dieciocho años. En función de esta peculiar distribución de mortalidad se discuten hipótesis alternativas sobre los escenarios en los que los homininos fueron aprehendidos y las implicaciones que ello

1988-12-01

Full Text Available The revision of the echinoderms from Collado de Tosas, based on the original specimens and additional material, is undertaken. The study shows that the initial attribution to the genus Trochocystites belonging to the Homalozoa Cincta has been induced by the tectonic deformation and the presence of recristallization lamellae in the natural molds. New observations allow to conclude without ambiguity that these skeletal elements are isolated columnals with a broad lumen, of crinoids. The presence of Cambrian in the section, established exclusively on the initial determinations, cannot longer be maintained.Los fósiles de Equinodermos del Collado de Tosas fueron dados a conocer en 1911 por F. Azpeitia que los atribuyó a Trochocystites bohemicus Bar. Posteriormente, M. Faura (1912 hizo notar la presencia de fósiles ordovícicos en esta misma localidad, y propuso una interpretación estratigráfica que incluía un contacto anómalo con el supuesto Cámbrico determinado por los Trochocystites. Todo ello fue revisado por B. Meléndez en 1954, que creyó poder confirmar que los fósiles en cuestión (fig. 1, eran realmente Carpoideos. El estudio de nuevo material recogido in situ, así como de los ejemplares conservados en el Museo del Seminario Conciliar de Barcelona, nos ha llevado a la conclusión de que la atribución inicial de estos discutidos fósiles al género Trochocystites, fue debida a la deformación tectónica que les ha dado forma ovalada, y a la presencia de láminas de recristalización, en disposición radial, en los moldes (fig. 6, lám. 1, que dan la falsa apariencia de placas marginales. Las nuevas observaciones nos permiten afirmar que estos fósiles son placas columnales, aisladas, probablemente del pedúnculo de Crinoides, con cavidad central muy amplia (Iám. 1, figs. 15, aunque eventualmente, también podrían haber pertenecido a Cystideos. En consecuencia, la presencia del Cámbrico en esta localidad, basada únicamente en la

RA reactor is not in operation since 1984, activities related to revitalisation of the RA reactor started in 1986. The planned actions related to renewal of the reactor components were finished except for the most important action, related to exchange of complete reactor instrumentation which was delayed. Only 80% of the instrumentation was delivered until September 1991. Since then any delivery of components to Yugoslavia was stopped because of the sanctions imposed to our country. The existing RA reactor instrumentation was dismantled. Control and maintenance of the reactor components was done regularly and efficiently. Fuel inspection by the IAEA safeguards inspectors was done on a monthly basis. There have been on the average 42 employees at the RA reactor which is considered sufficient for maintenance and repair conditions. The problem of financing the reactor activities and maintenance remains unsolved. Research reactor RA Annual report for year 1997 is divided into two main parts to cover: (1) operation and maintenance and (2) activities related to radiation protection.

Full Text Available Submarine volcanic rocks (pillow lavas appear into the marly limestones and marls of the Capas Rojas Formation in the Median Subbetic. The dating with nannoplankton of the immediately underlying and overlying materials to these volcanic rocks has allow us to precise the age of this volcanic activity as Late Santonian (nannofossil biozone of Rucinolithus hayi. This volcanic event arose 84 million years ago, according to the absolute age obtained with the calibration of this biozone. It is the last Mesozoic volcanic activity registered until now in the External Zones of the Betic Cordilleras. The age of this event corresponds to the ending part of the interval of the Sudiberian continental margin evolution as an extensive margin, relatively nearly to the time in which it evolved to a convergent marginRocas volcánicas submarinas (lavas almohadilladas aparecen intercaladas entre calizas margosas y margas de la Formación Capas Rojas del Subbético Medio.

Full Text Available Predmet rada jeste primena Lambertovog vođenja na balističku raketu. Koristeći fundamentalnu jednačinu za upravljački vektor brzine razvijena je formula za određivanje ugla orijentacije vektora potiska u zavisnosti od faktora rotacije njegovog pravca. Izvedena formula zahteva Q-matricu koja povezuje diferencijalnu promenu vektora položaja rakete sa odgovarajućom diferencijalnom promenom korelisane brzine za fiksnu poziciju cilja i konstantno vreme slobodnog leta rakete. Izborom parametra rotacije vektora potiska dobijaju se različiti profili ugaonog položaja rakete i ugla njene brzine u zavisnosti od vremena. Podešavanjem parametra rotacije vektora potiska moguće je ostvariti prekid rada raketnog motora pri nultom napadnom uglu i, na taj način, smanjiti početne poremećaje slobodnog leta rakete. / This paper deals with the application of the Lambert guidance to the ballistic missile. By using the fundamental equation for the velocity-to-be-gained, the demanded command for the thrust angle is developed in terms of the rotational factor of its direction. The developed formula requires the Q-matrix which links a differential change in the missile position vector to the corresponding differential change in the correlated velocity for the fixed target position and the constant time of free flight. The choice of the rotational parameter provides different profiles of the missile attitude and flight path angle with time. By adjusting the rotational parameter for the thrust vector, the cut-off of the rocket engine can occur at zero angle of attack and the initial perturbations during free flight may be thus reduced.

W wyniku przeprowadzonych badań, dziewięciu biegłych rewidentów na dziesięciu uznało, że weryfikacja założenia o kontynuacji działalności jest kluczowa z punktu widzenia badania sprawozdań finansowych. Jednocześnie zaledwie trzech biegłych rewidentów wskazało, że wie, czym są modele dyskryminacyjne oraz oświadczyło, że rozumie sposób ich działania, a tylko jedna osoba potwierdziła, że korzystała z tego rodzaju modeli przy ocenie założenia o kontynuacji działalności. Po- nadto, pomimo rosnącego wykorzystania analizy dyskryminacyjnej do oceny sytuacji finansowej przed- siębiorstw wyestymowane do tej pory modele nie były skierowane do użycia bezpośrednio przez bie- głych rewidentów. Biorąc to pod uwagę, próba stworzenia modeli dyskryminacyjnych dla biegłych rewi- dentów nie jest tematem błahym i pozostaje atrakcyjnym obszarem do prowadzenia badań naukowych.

Review of problems and methods for radiation risk assessment in the environment of a nuclear power plant; Pregled problematike in metodologije ocenjivanja radijacijske nevarnosti za okolico nuklearne elektrane

Radiation impact on the nuclear power plant environment is a very important problem which has to be solved during design and construction. Damage that could be caused by release of radioactive material into the environment should be estimated and the magnitude of nuclear and radiation risk of the power plant should be evaluated. In general the accuracy of estimation is rather poor due to statistical fluctuations of the conditions which influence radioactivity expansion in the environment, especially in the air. Different uncertainties and unresolved problems influence the inaccuracy. Since any real risk should be extremely small compared to potential risk i.e. risk induced by nuclear power plant without any safety measures, even inaccurate estimations are very useful. Method for environmental radiation risk assessment is based on relatively simple models of radiation expansion in the environment and in the air. These models are theoretically solved but they are based on relatively limited number of experimental data. Assessment of the radiation effects on the population health and mortality is an important problem. [Slovenian] Radiacijska nevarnost za okolico nuklearne elektrarne je zelo vazen problem, ki ga je treba resiti ze pri projektiranju in gradnji. Treba je oceniti skodo, ki bi jo povzrocila v okolici neka dolocena sprostitev radioaktivnosti in na osnovi tega dimenzionirati ukrepe nuklearne in radiacijske varnosti same elektrarne. Natancnost ocenjevanja je v splosnem zelo slaba. Temu so v precejsnji meri krive statisticne fluktuacije pogojev, ki vplivajo na razsirjanje radioaktivnosti v okolici, ziasti po zraku. Na nenatancnost pa vplivajo tudi razne nejasnosti in se nereseni problemi. Ken pa mora biti dejanska nevarnost izredno majhna v primerjavi s potencialne nevarnostjo oziroma z nevannostjo, ki bi jo predstavjala nuklearna elektrarna, ce bi zanemarili vse varnostne ukrepe, so tudi taksne nenatancne ocene zelo koristne.

ICESat-derived lithospheric flexure as caused by an endorheic lake's expansion on the Tibetan Plateau and the comparison to modeled flexural responses

Science.gov (United States)

Madson, Austin; Sheng, Yongwei; Song, Chunqiao

2017-10-01

A substantial and rapid expansion beginning in the late 1990s of Siling Co, the largest endorheic lake on the central Tibetan Plateau (TP), has caused a measurable lithospheric deflection in the region adjacent to the lake. Current broad-scale measuring of this flexural response is mainly derived from InSAR processing techniques or time-consuming field campaigns. The rheological constraints of the lithosphere from the underlying lithospheric response to large lake loads in this region are not well understood. This paper highlights a more efficient spaceborne LiDAR remote sensing technique to measure the deflection in the vicinity of Siling Co and to investigate the mechanisms of the observed lithospheric response in order to garner a better understanding of the local rheology. A lake-adjacent deflection rate and Siling Co water load variations are calculated utilizing the Geoscience Laser Altimeter System (GLAS) onboard NASA's Ice, Cloud and land Elevation Satellite (ICESat) and the joint NASA/USGS Landsat series of Earth observing satellites. A downward deflection rate of ∼5.6 mm/yr for the first 4 km of lake-adjacent land is calculated from the GLAS instrument, and this response is compared to the flexural outputs from a spherically symmetric, non-rotating, elastic, and isotropic (SNREI) Earth model in order to better understand the underlying mechanisms of the lithospheric response to the rapid increase of Siling Co loads. The modeled elastic response is ∼6.9 times lower than the GLAS derived flexure, thereby providing further evidence that a purely elastic lithospheric response cannot explain the deflection in this region. The relationship between the modeled elastic response and the GLAS derived flexure is applied to a long-term lake load change dataset to create the longest-running flexural response curve as caused by the last ∼40 years of Siling Co load variations, and these results show an accumulated lake-adjacent flexure of ∼12.6 cm from an

The plan for 1975 was successfully fulfilled. This is reflected in research related to improvement of operating properties of the RA reactor, mostly due to the effort of the RA staff employed in operation and maintenance of the reactor. Fuel saving achieved by this activity amounted to about 38% (80% enriched fuel). Preliminary work is done, concerned with new reactor core with highly enriched fuel. This is a significant saving as well. New fuel elements have arrived at the end of this year. It is going to enable increase of neutron flux by 50% without changing the nominal operating power. The possibility of further improvement of the reactor are analyzed, to enable material testing and production of radioactive sources. Mid term plan for reactor operation was made according to this analysis. It is planned to further increase the neutron flux in isolated smaller zones, and building new experimental loops with cooling and fast neutron converters. Much was done to increase the safety level of reactor operation and preparing the safety report. [Serbo-Croat] Izvrsenje zadataka u 1975. godini bilo je uspesno. To se ogleda u povecanju istrazivackog rada vezanog za poboljsanje eksploatacionih karakteristika reaktora RA, pretezno koriscenjem sopstvenog kadra angazovanog u pogonu i odrzavanju reaktora. Ovim radom postignuta je usteda goriva od oko 38% (80% obogaceno gorivo). Izvrseni su preliminarni radovi na prevodjenju reaktora RA na novo gorivo, sto je takodje velika usteda. Novo gorivo je stiglo krajem godine i ono ce obezbediti porast neutronskog fluksa od 50%, bez promene nominalne snage reaktora. Izvrsena je analiza mogucnosti daljeg usavrsavanja reaktora za potrebe ispitivanja materijala kao i proizvodnju radioaktivnih izvora. Na osnovu ove analize nacinjen je srednjorocni program rada reaktora RA sa tezistem na daljem povecanju fluksa u izdvojenim manjim zonama i ugradnju 'hladjenih petlji' i brzih konvertora. Mnogo je ucinjeno na povecanju stepena sigurnosti

Possibilities of using metal uranium fuel in heavy water reactors; Mogucnosti upotrebe metalnog urana kao goriva za teskovodne reaktore

Energy Technology Data Exchange (ETDEWEB)

Djuric, B; Mihajlovic, A; Drobnjak, Dj [Institute of nuclear sciences Boris Kidric, Vinca, Beograd (Yugoslavia)

1965-11-15

There are serious economic reasons for using metal uranium in heavy water reactors, because of its high density, i.e. high conversion factor, and low cost of fuel elements production. Most important disadvantages are swelling at high burnup and corrosion risk. Some design concepts and application of improved uranium obtained by alloying are promising for achievement of satisfactory stability of metal uranium under reactor operation conditions. Postoje ozbiljni ekonomski razlozi za primenu metalnog urana u teskovodnim reaktorima, pre svega zbog njegove velike gustine, odnosno visokog konverzionog faktora, i zbog niskih troskova proizvodnje gorivnih elemenata. Glavne prepreke su bubrenje pri velikim stepenima sagorevanja i opasnost od korozije. Postoje veliki izgledi da se primenom odredjenih projektnih koncepcija i upotrebom legiranjem poboljsanog urana postigne zadovoljavajuca stabilnost metalnog urana u uslovima rada reaktora (author)

Casimir, M J

1975-01-01

An eastern gorilla group of the Mt. Kahuzi region (République du Zaïre) was studied over 15 months. Its migration route was determined, and the various biotopes it visited are described. A record was made of its main food plants, and of the plant parts eaten. For nine important food plants the protein content, the concentration of the individual amino acids and the water content were measured for the plant parts eaten and for those not eaten. For some of these plant parts the Na, K, Ca and Mg content were also determined. No general correlation between food selection and one or several of these factors could be found. The development and value of a traditionally determined mixed diet is discussed.

Paleoecología: el uso de los quironómidos fósiles (Diptera: Chironomidae en reconstrucciones paleoambientales durante el Cuaternario en la Patagonia Paleoecology: the use of fossil chironomids (Diptera: Chironomidae for paleoenvironmental reconstructions in Patagonia

Full Text Available Entre los indicadores biológicos lacustres más utilizados en las reconstrucciones ambientales, se encuentran el polen, los ostrácodos y las diatomeas, y entre los insectos, los coleópteros y los quironómidos. Este grupo ha cobrado gran importancia en los últimos tiempos, debido a los resultados prometedores que se han obtenido en reconstrucciones climáticas realizadas en América del Norte y Europa. En América del Sur, el uso de los quironómidos fósiles en estudios cuaternarios es relativamente limitado, principalmente por su escaso conocimiento taxonómico regional. La mayor parte de estos estudios fueron realizados en lagos glaciares patagónicos de Argentina y Chile. Las larvas de quironómidos constituyen una valiosa herramienta paleolimnológica, por ser un grupo de organismos altamente sensible a cambios ambientales, tanto naturales como artificiales. Además, es un grupo de insectos ampliamente distribuido y con una abundancia y diversidad relativamente altas. Sus cápsulas cefálicas se preservan en los sedimentos lacustres y poseen caracteres importantes que permiten identificar géneros y muchas veces especies. El estudio de los ensambles de quironómidos en sedimentos lacustres puede ser utilizado con distintos objetivos, por ejemplo, para estudios de eutrofización, ya que responden rápidamente a cambios en la concentración de nutrientes, materia orgánica y otros elementos, como metales pesados. No obstante, uno de los potenciales más importantes de este grupo de insectos es su sensibilidad a los cambios de temperatura, por este motivo, la aplicación más importante de su estudio en sedimentos se centra en las reconstrucciones climáticas. Esta contribución es una síntesis de los resultados de los trabajos publicados en la Patagonia argentina y chilena, sobre la base del uso de los quironómidos fósiles en reconstrucciones paleoambientales.Pollen, ostracods, diatoms and insects such as beetles and chironomids are

Ovi filtri su primenjeni u sistemima za praćenje uz pomoć infracrvenih senzora. Određivanje nivoa praga filtriranja vrši se uz pomoć statističkih osobina slike. Veoma važan korak u procesu praćenja je određivanje prozora praćenja, koji maze biti, po dimenzijama, fiksan ili adaptibilan. Pogrešna procena o postojanju cilja u prozoru može se doneti u slučaju prisustva šuma pozadine, predpojačavača, detektora, itd. Filtriranje je neophodan korak u ovim sistemima, kao značajan činilac U povećanju brzine i tačnosti praćenja. / A case of image filtering in air target detecting and tracking systems is described in this paper. Two image filtering methods are given. The first method is performed using a low pass convolving filter and the second one uses the mean value of gray level filter. The main goal of the cited filtering is implementation in IR (infra red systems. Some statistical features of the images were used for selecting the threshold level. The next step in the algorithm is the determination of a 'tracking window' that can be fixed or adaptive in size. A false estimation of a target existing in the window may be influenced by the background noise, low noise amplifier detector, etc.

2018-05-01

In this paper, a continuous and dense coating was deposited on samples of the ZA27 alloy through the plasma electrolytic oxidation (PEO) process to improve its wear and corrosion performance. A nontoxic and environmentally friendly inorganic salt, Na2SiO3, is chosen as electrolytes with different concentrations. The effect of the concentration of Na2SiO3 aqueous solutions on the coating performances was investigated. The coatings with 3Al2O3·2SiO2 (mullite), Zn2SiO4 and Al2O3 (either crystal phase or with some amorphous SiO2 phases) were formed by the PEO processes. It was found that the coating thickness increased with the increase in electrolyte concentration. However, the wear and corrosion resistance performance of the coatings did not improve as the coating's thickness increased. This was due to the fact that the coating produced with electrolytes of 10 g/L has a porous structure with large pore size. Among all the samples, coating produced by 15 g/L Na2SiO3 has the best wear and corrosion resistance, which is attributed to its continuous and dense structure with thickness of about 47 μm.

Full Text Available U periodu dužem od stotinu godina fotogrametrija je imala i još uvijek ima veoma važnu ulogu u dokumentaciji kulturno-historijskog naslijeđa. Odabirom ispravne tehnologije omogućena je zaštita, očuvanje i valorizacija arhitektonskih, arheoloških i svih drugih oblika kulturne baštine. Mnoga nedavna tehnološka otkrića unaprijedila su fotogrametriju kao alat za snimanje, omogućavajući mnogo komplikovanija predstavljanja objekata. Na taj način je osiguran vjeran prikaz stvarnog svijeta, kao i brz protok podataka od stručnjaka do zainteresovanih korisnika. U ovom radu objašnjena je važnost očuvanja i dokumentiranja kulturno-historijske baštine. Dati su zanimljivi primjeri dokumentiranja kulturno-historijske baštine iz svijeta i Bosne i Hercegovine, korištenjem blizupredmetne fotogrametrije i laserskog skeniranja. : During the period of one hundred years photogrammetry has had and still has a very important role in the documentation of cultural heritage. Selecting proper technologies enabled the protection, preservation and valorisation of architectural, archaeological and other forms of cultural heritage. Many recent technological breakthroughs have improved photogrammetry, as a tool for capturing, allowing a representation of much more complicated objects. In this way the faithful representation of the real world as a fast flow of information from the experts to the user has been secured. This paper explains the importance of preserving and documenting the cultural and historical heritage. Interesting examples of documenting the cultural and historical heritage of the world and Bosnia and Herzegovina are given, using close-range photogrammetry and laser scanning.

During 1973, RA reactor was operated at nominal power for 4687 hours and 54 hours at lower power levels. The total production was 30504 MWh which is 1.6% higher than planned. Practically there was no discrepancies from the plan, since the action plan was corrected at the beginning of this year caused by the demand of changing the schedule for refuelling for the purpose of 'power excursion' experiment. The reactor was used for irradiation and experiments according to the demand of 336 users. This report contains detailed data about reactor power and experiments performed in 1973. Total number safety shutdowns was 12, of which 7 were caused by power cuts. Three shutdowns caused by failures of the equipment were caused by failures of new electronic tubes. Two shutdowns were caused by the operators. There have been three shorter interruptions announced power cuts. Total personnel exposure dose was lower than during previous years. There were no accidents during this year. Decontamination of surfaces was less than during previous years. Practically there was no surface contamination, and the quantity of collected radioactive waste was lower than previously. There were no liquid radioactive effluents. It was concluded that the successful operation in 1973 has a special significance taking into account the financial crisis. There still remains a number of unsolved problems related to: completing the inventory of spare parts, exchange of some elements of the equipment, exchange of instrumentation, and purchase of the highly enriched fuel. [Serbo-Croat] Reaktor RA je u 1973. godini radio na nominalnoj snazi 4687 sati i 54 sata na manjim snagama. Ukupni rad iznosio je 30504 MWh odnosno 1,6% vise od planiranog. Prakticno nije bilo odstupanja od plana rada koji je pocetkom godine korigovan zbog promene planiranih izmena goriva usled izvodjenja eksperimenta 'ekskurzije snage'.

Full Text Available A quick revision of the available information on the life and works of Ibn Abī l-Rijāl (fl. Tunis ca. 996-1048 and an analysis of the contents of his Urjūza fī aḥkām al-nuŷūm which are compared to those of his better known Kitāb al- Barī‘ fī aḥkām al-nujūm. The conclusion is that both works are independent and that the Urjūza is not a summary of the Barī‘. The paper continues with biobibliographical data of the historian, mathematician and astrologer Ibn Qunfudh al-Qusanṭīnī (1339-1407, who is the author of a commentary of Ibn Abī l-Rijāl’s Urjūza dedicated to Abū Bakr b. Abī Mujāhid Gazī Ibn al-Kās, vizier of the Merinid sultans Abū Fāris (1366-1372 and Abū Zayyān (1372-1374. The work was probably written during the latter’s brief reign and before 1375, the date in which the dedicatee was exiled to Majorca. The work continues with an analysis of the contents of the commentary, the sources quoted, the astrological techniques used both by Ibn Qunfudh and by Ibn Abī l-Rijāl, and the use by the commentator of a set of astronomical tables derived from the zīj of Ibn Isḥāq. We find, finally, a detailed commentary of the horoscopes contained in Ibn Qunfudh’s work which includes one corresponding to the vernal equinox of the year 571 AD, in which there was a conjunction of Saturn and Jupiter which announced the arrival of Islam. There are eleven more horoscopes (two of them published previously which constitute an astrological history of Merinid Morocco between 1348 and 1366. Concerning the nine horoscopes analysed here, in six of them it has been possible to identify the subject or the event motivating the prediction, while three remain unidentified.

Full Text Available The paleontological site of Las Higueruelas presents a singular opportunity to study diagenetic processes in a complex taphonomical context. Numerous Pliocene vertebrate and invertebrate fossils were preserved in particular lagoonal and volcaniclastic conditions. The diagenetic processes were studied in molars of the equid Hipparion and in ribs of the mastodont Anancus and were compared with the mineralisation in the molars horse and ribs of the recent elephant Loxodonta. In the fossils, the cementation with carbonate is predominant, as seen in cavities in the fossils which are filled with carbonate micrite without dolomitisation. The presence of basaltic rock fragments, which are intercalated with the fossiliferous levels cause a marked enrichment in heavy metals, especially in the less compate elements. Diagenesis resulted in different chemical and physical changes in the fossils studied (molars and ribs.El yacimiento de Las Higueruelas constituye un escenario singular para el estudio de procesos diagenéticos relacionados con un contexto tafonómico complejo.

During the reporting period the reactor was permanently ready for operation and responding to the demands of the experimenters. The reactor was operating for 408.5 hours at power levels from 50 - 5000 kW, or 1985 MWh in total, burnup of the first batch of fuel was 22.55%. Reactor core was made of 56 fuel channels. Activities related to construction of new and improvement of the existing equipment was continued in order to enable safe operation and successful utilization of the RA reactor. Exchange of the electronic tubes was continued in order to increase the stability of the reactor control and reactor protection systems. About 65% of tubes planned to be exchanged this year was done. Cooperation with the CEN Saclay, France related to construction of experimental loops VISA-1 and VISA-2 was continued as well as cooperation with Poland concerned with exchange of experts. The problem of lack of properly trained staff was nor solved. [Serbo-Croat] U izvestajnom periodu reaktor je uvek bio spreman za rad i odgovarao je zahtevima eksperimentatora.

Full Text Available A synthesis of the vertebrate fossil record of Abocador de Can Mata (els Hostalets de Pierola, Vallès-Penedès Neogene basin is reported, with special emphasis on taxonomic and biostratigraphic aspects. For the moment being, this macrosite includes a succession of 91 micro- and/or macrovertebrate sampled localities, which are distributed along about 300 m of stratigraphic series, spanning a time interval of more than a million years, corresponding to the late Aragonian. During the 28 months of field work performed along the 2002-2003, 2004 and 2005 campaigns, more than 15,000 macrovertebrate fossil remains and more than 1,300 small mammal teeth have been recovered—an amount that shall be surely increased in the future, when sieving and sorting of the accumulated sediments is finished. An exhaustive list of all the localities and their stratigraphic contextualization is reported for the first time, along with an updated faunal list and a proposal of local biozonation. The great fossiliferous richness of that area and the huge sampling effort, combined with the requirements of current laws on the protection of paleontological patrimony, explain the success of the paleontological intervention. To sum up, the extension of Can Mata’s rubbish dump provides a unique opportunity for investigating the faunal composition of terrestrial ecosystems from the late Aragonian in Southwestern Europe.Se presenta una síntesis del registro de vertebrados fósiles del Abocador de Can Mata (els Hostalets de Pierola, cuenca neógena del Vallès-Penedès, con especial énfasis en los aspectos taxonómico y bioestratigráfico.

Deep penetration multichannel reflection and Ocean Bottom Seismometer wide-angle seismic data from the Congo-Angola margin were collected in 2000 during the ZaïAngo cruise. These data help constrain the deep structure of the continental margin, the geometry of the pre-salt sediment layers and the geometry of the Aptian salt layer. Dating the deposition of the salt relative to the chronology of the margin formation is an issue of fundamental importance for reconstructing the evolution of the margin and for the understanding of the crustal thinning processes. The data show that the crust thins abruptly, from a 30-40 km thickness to less than 10 km, over a lateral distance of less than 50 km. The transitional domain is a 180-km-wide basin. The pre-salt sediment layering within this basin is parallel to the base of the salt and hardly affected by tectonic deformation. In addition, the presence of a continuous salt cover, from the continental platform down to the presumed oceanic boundary, provides indications on the conditions of salt deposition that constrain the geometry of the margin at that time. These crucial observations imply shallow deposition environments during the rifting and suggest that vertical motions prevailed-compared to horizontal motions-during the formation of the basin.

Is Administration of Trastuzumab an Independent Risk Factor for Developing Osteonecrosis of the Jaw Among Metastatic Breast Cancer Patients Under Zoledronic Acid Treatment?

Abstract One of the most important adverse effects of zoledronic acid (ZA) is osteonecrosis of the jaw (ONJ). In previous literature, several risk factors have been identified in the development of ONJ. In this study, we aimed to determine the role of trastuzumab, an antiangiogenic agent, as an independent risk factor for the development of this serious side effect. Our study included 97 patients (mean age: 54 ± 10 years) with breast cancer, recorded in the archives of the Istanbul Florence Nightingale Breast Study Group, who received ZA therapy due to bone metastases between March 2006 and December 2013. We recorded the patients’ ages, weights, duration of treatment with ZA, number of ZA infusions, dental procedures, anticancer treatments (chemotherapy, aromatase inhibitor, trastuzumab), the presence of diabetes mellitus or renal dysfunction, and smoking habits. Thirteen patients (13.40%) had developed ONJ. Among the patients with ONJ, the mean time of exposure to ZA was 41 months (range: 13–82) and the mean number of ZA infusions was 38 (range: 15–56). The duration of treatment with ZA and the use of trastuzumab were observed to be 2 factors that influenced the development of ONJ (P = 0.049 and P = 0.028, respectively). The development of ONJ under ZA treatment may be associated solely with the duration of ZA treatment and the concurrent administration of trastuzumab. These findings show that patients who are administered trastuzumab for metastatic breast cancer while undergoing ZA treatment are prone to developing ONJ. Therefore, we recommend intense clinical observation to avoid this particular condition in patients receiving ZA and trastuzumab. PMID:25950681

This study was carried out to assess the compatibility of the biocontrol fungus Clonostachys rosea IK726 with the phenazine-producing Pseudomonas chlororaphis ToZa7 or with the prodigiosin-producing Serratia rubidaea S55 against Fusarium oxysporum f. sp. radicis-lycopersici. The pathogen was inhibited by both strains in vitro, whereas C. rosea displayed high tolerance to S. rubidaea but not to P. chlororaphis. We hypothesized that this could be attributed to the ATP-binding cassette (ABC) proteins. The results of the reverse transcription quantitative PCR showed an induction of seven genes (abcB1, abcB20, abcB26, abcC12, abcC12, abcG8 and abcG25) from subfamilies B, C and G. In planta experiments showed a significant reduction in foot and root rot on tomato plants inoculated with C. rosea and P. chlororaphis. This study demonstrates the potential for combining different biocontrol agents and suggests an involvement of ABC transporters in secondary metabolite tolerance in C. rosea.

Previously we showed that repeated vaginal application of a MIV-150/zinc acetate carrageenan (MIV-150/ZA/CG) gel and a zinc acetate carrageenan (ZA/CG) gel significantly protected macaques from vaginal simian human immunodeficiency virus reverse transcriptase (SHIV-RT) infection. Gels were applied either daily for 2 weeks or every other day for 4 weeks, and the animals were challenged 4-24 h later. Herein, we examined the effects of a single vaginal dose administered either before or after virus challenge. Encouraged by the vaginal protection seen with MIV-150/ZA/CG, we also tested it rectally. Vaginal applications of MIV-150/ZA/CG, ZA/CG, and CG gel were performed once 8-24 h before, 1 h after, or 24 h before and 1 h after vaginal challenge. Rectal applications of MIV-150/ZA/CG and CG gel were performed once 8 or 24 h before rectal challenge. While vaginal pre-challenge and pre/post-challenge application of MIV-150/ZA/CG gel offered significant protection (88%, pinfection prechallenge, but not significantly, and the effect was completely lost post-challenge. Rectal application of MIV-150/ZA/CG gel afforded limited protection against rectal challenge when applied 8-24 h before challenge. Thus, MIV-150/ZA/CG gel is a highly effective vaginal microbicide that demonstrates 24 h of protection from vaginal infection and may demonstrate efficacy against rectal infection when given close to the time of HIV exposure.

Poudari, da so nekateri pisci sprva zmotno primerjali model začetnega izobraževanja in prenos kulture, ki se vrši tam z dopolnilnim izobraževanjem. Začetno izobraževanje, ki ga zasnuje država, je moč obravnavati kat celoto in ga tudi kat celoto skupaj s kulturo, na kateri temelji, prenesti na tuja tla. Dopolnilno izobraževanje odraslih zasnuje skupina posameznikov. Še več, dopolnilno izobraževanje ne velja za celo državno področje, taka kat začetno.

Auxiliary enzymes participate in β-oxidation of unsaturated fatty acids. The objective of the study was to investigate the impact of a moderate zinc deficiency and a high intake of polyunsaturated fat on Δ(3)Δ(2)-enoyl-CoA isomerase (ECI) in the liver and other tissues. Five groups of eight weanling rats each were fed moderately zinc-deficient (ZD) or zinc-adequate (ZA) semisynthetic diets (7 or 50 mg Zn/kg) enriched with 22 % cocoa butter (CB) or 22 % safflower oil (SO) for 4 weeks: (1) ZD-CB, fed free choice; (2) ZA-CBR, ZA-CB diet fed in equivalent amounts consumed by the ZD-CB group; (3) ZD-SO, fed free choice; (4) ZA-SOR, ZA-SO diet fed in equivalent amounts consumed by the ZD-SO group; and (5) ZA-SO, fed free choice. Growth and Zn status markers were markedly reduced in the ZD groups. ECI activity in the liver of the animals fed the ZD- and ZA-SO diets were significantly higher (approximately 2- and 3-fold, respectively) as compared with the CB-fed animals, whereas activities in extrahepatic tissues (kidneys, heart, skeletal muscle, testes, adipose tissue) were not altered by dietary treatments. Transcript levels of the mitochondrial Eci gene in the liver did not significantly differ between ZD and ZA rats, but were 1.6-fold higher in the ZA-SO- than in the ZD-CB-fed animals (P safflower oil as a source high in linoleic acid induce markedly increased hepatic ECI activities and that a moderate Zn deficiency does not affect transcription of the mitochondrial Eci gene in the liver.

RA reactor operation and maintenance in 1989, Part 1; Deo 1 - Pogon i odrzavanje nuklearnog reaktora RA u 1989. godini

During the previous period RA reactor was not operated because the Committee of Serbian ministry for health and social care has cancelled the operation licence in July 1984. The reason was the non existing emergency cooling system and lack of appropriate filters in the special ventilation system. The following major tasks were fulfilled: building of the new emergency cooling system, reconstruction of the existing ventilation system, and renewal of the power supply system. Project concerned with renewal of RA reactor complete instrumentation was started at the end of 1988. Contract was signed between the IAEA and Soviet Atomenergoexport for supplying the new instrumentation for the RA reactor. Project concerned with increase of the storage space and the efficiency of handling the spent fuel elements has started in 1988. In 1989, device for water purification designed by the reactor staff started operation and spent fuel handling equipment is being mounted. Training of the existing personnel and was done regularly, but the new staff has no practical training since the reactor is not operated. Lack of financial support influenced strongly the status of RA reactor. [Serbo-Croat] U proteklom periodu reaktor RA nije bio u pogonu zato sto je 30. jula 1984. Republicki komitet za zdravlje i socijalnu politiku republike Srbije, zabranio njegov rad zbog toga sto reaktor ne poseduje sistem za udesno hladjenje i ne poseduje odgovarajuce filtere u sistemu specijalne ventilacije. Zavrseni su radovi na izgradnji sistema za udesno hladjenje, rekonstrukciji postojeceg sistema specijalne ventilacije i rekonstrukciji sistema za napajanje elektricnom energijom. Krajem 1988, medjunarodna agencija za atomsku energiju potpisala je ugovor sa sovjetskom firmom Atomergexport za izradu novog sistema instrumentacije. Sa ciljem da se poveca i efikasnije koristi prostor za skladistenje ozracenog goriva, 1987. godine zapoceta je realizacija projekata preciscavanja vode u bazenima za odlezavanje

The managing process is, therefore, often considered as equal with the decision making process, which shows that decision making plays a significant role in the managing process of organizations. Managing efficiency as well as functioning and development of every organization depends on decision making correctness, i.e. on the correctness of undertaken actions. The Serbian Armed Forces is an organizational system where the managing process is carried out as well. The levels of decision importance in the Army are different, from daily-operative to strategic ones, but the importance of the decision making process itself is equal, regardless the level of decisions. Decision makers sometimes face situations when they have only one action and in that case the decision making process is reduced to either accepting or refusing the action. However, decision makers often face a situation when, by ranking many offered actions, they decide which one is the best. Ranking itself is carried out by evaluating offered actions, and the selection is made based on the best results of an action. These conclusions require a careful and systematical approach to the decision making process, regardless the decision type, since any wrong decision leads to the weakening of the combat readiness of The Serbian Armed Forces.

This study aimed to check the effect of zoledronic acid (ZA) at subtoxic dose on human osteoblasts (HOs) in terms of cell viability, apoptosis occurrence, and differentiation induction. ZA belongs to the family of bisphosphonates (BPs), largely used in the clinical practice for the treatment of bone diseases, often associated with jaw osteonecrosis onset. Their pharmacological action consists in the direct block of the osteoclast-mediated bone resorption along with indirect action on osteoblasts. HOs were treated choosing the highest limit concentration (10(-5) M) which does not induce toxic effects. Live/dead staining, flow cytometry, mitochondrial membrane potential assay, osteocalcin western blotting, gp38 RT-PCR, collagen type I, PGE2, and IL-6 ELISA assays were performed. Similar viability level between control and ZA-treated samples is found along with no significant increase of apoptotic and necrotic cells in ZA-treated sample. To establish if an early apoptotic pathway was triggered, Bax expression and mitochondrial membrane potential were evaluated finding a higher protein expression in control sample and a good integrity of mitochondrial membrane in both experimental points. Type I collagen secretion and alkaline phosphatase (ALP) activity appear increased in ZA-treated sample, osteocalcin expression level is reduced in ZA-treated cells, whereas no modifications of gp38 mRNA level are evidenced. No statistical differences are identified in PGE2 secretion level whereas IL-6 secretion is lower in ZA-treated HOs with respect to control ones. These results highlight that ZA, delaying the osteoblastic differentiation process versus the osteocytic lineage, strengthens its pharmacological activity enhancing bone density. The knowledge of ZA effects on osteoblasts at subtoxic dose allows to improve therapeutic protocols in order to strengthen drug pharmacological activity through a combined action on both osteoclastic and osteoblastic cells.

This study investigated the effects of zoledronic acid (ZA) on radiation-induced bone loss in C3H/HeN mice. C3H/HeN mice were divided into sham control and three irradiated groups (3 Gy, gamma ray). The irradiated mice were treated for 12 weeks with vehicle, amifostine (intraperitoneal injection), or ZA (subcutaneous injection). Grip strength, uterus weight, and serum alkaline phosphatase (ALP), and tartrate-resistant acid phosphatase (TRAP) levels were measured. Tibiae were analyzed using micro-computed tomography. Treatment of ZA (100 μg·kg{sup -1}·week{sup -1}) significantly preserved trabecular bone volume, trabecular thickness, trabecular number, trabecular separation, bone mineral density of proximal tibia metaphysic, and cortical bone volume, but did not alter the uterus weight of the mice. The administration of ZA for 12 weeks lowered serum ALP and TRAP levels in irradiated mice, suggesting that ZA can reduce the bone turnover rate in mice. No differences were apparent between the amifostine-treated group and the irradiation control group. The results indicate that ZA can prevent radiation-induced bone loss in mice.

Bisphosphonates are widely used in metastatic cancer such as prostate and breast cancer, and their nephrotoxic effects have been established previously. In this study we aimed to evaluate both the nephrotoxic effects of zoledronic acid (ZA) and the protective effects of vitamin E (Vit-E) on this process under light and electron microscopy. A total of 30 male Sprague-Dawley rats were divided into 3 groups. The first group constituted the control group. The second group was given i.v. ZA of 3 mg/kg once every 3 weeks for 12 weeks from the tail vein. The third group received the same dosage of ZA with an additional i.m . injection of 15 mg Vit-E every week for 12 weeks. Tissues were taken 4 days after the last dose of ZA for histopathological and ultrastructural evaluation. Paller score, tubular epithelial thickness and basal membrane thickness were calculated for each group. For group 2, the p -values are all < 0.001 for Paller score, epitelial thickness, and basal membrane thickness. For group 3 (ZA + Vit. E), the p -values are < 0.001 for Paller score, 0.996 for epitelial thickness, and < 0.001 basal membrane thickness. Significant differences were also observed in ultrastructural changes for group 2. However, adding Vit-E to ZA administration reversed all the histopathological changes to some degree, with statistical significance. Administration of ZA had nephrotoxic effects on rat kidney observed under both light and electron microscopy. Concomitant administration of Vit-E significantly reduces toxic histopathological effects of ZA.

This report describes the task concerned with measurements of neutron flux in four experimental channels, called VISA-2 channels. All the channels are made of aluminium tubes, one is sealed to prevent contact of foils with heavy water, and are placed in the regular reactor lattice next to the central experimental channel VK-5. Measuring results, i.e. absolute values of neutron flux and flux distribution are needed for realisation of the VISA-2 project. Measurements of neutron flux are done by activation method. Activation foils are placed in cylindrical aluminium tubes specially prepared for this purpose and placed in VISA-2 channels. Foils are irradiated simultaneously for 5 hours at reactor power of 150 kW. Neutron flux distribution is determined by measuring the relative activity of cobalt foils. [Serbo-Croat] Ovaj izvestaj opisuje merenja neutronskog fluksa u cetiri eksperimentalna kanala VISA-2.

From Autobiography to Fiction, or Translating Géza Csáth’s Diary from Hungarian to French and to Polish

Full Text Available The aim of this paper is to analyze the complex relation between autobiography and fiction in the work of the Hungarian psychiatrist, writer and music critic Géza Csáth (the pen name of József Brenner [1887–1919], in particular his 1912–1913 diary, usually called the morfinista napló [diary of a morphine addict], by comparing its Polish and French translations as a means of highlighting alternative interpretations of the diary itself. Because the choices that were made when translating such fragmented texts already imply more or less developed interpretations of them, variations between them can be examined side by side in order to reveal sometimes widely diverging understandings of the diaries’ meaning, purpose and general structure. The decision-making that led to the translators’ choices is not only examined here case by case, but also in the context of an assumed overarching reading of these diaries, accounting for a sense of consistency in their differentiation patterns. Scrutinizing these choices allows for the discussion of relevant internal contradictions within the text itself, which in turn accounts for its richness and poetic value; they invite us to immerse ourselves into a world of tangled streams of thoughts where life and work crisscross, into a narrative that is neither a proper diary nor a novel. Beyond attempting to assess the degrees of validity of the given translations, this paper focuses mainly on showcasing them as alternative yet equally relevant interpretative stepping stones into Csáth’s monstrously complex and tormented literary world.

Evaluation of urban transformation areas in terms of user satisfaction: the case study of Zağnos Valley (Trabzon/Turkey).

Düzgüneş, Ertan; Saraç, Elif

2017-12-08

Following the Industrial Revolution, rapid urbanization brought about many socio-economic, physical, and cultural problems. The concept of urban transformation has come to the fore as a solution to these emerging troubles. Especially since 1980, in Turkey, like other developing countries, the concept of urban transformation has only been evaluated as an economic standpoint ignoring the social and spatial dimensions of that area and the quality of life of people residing in the area. Therefore, the necessity of these socially accessible areas where individuals can regenerate themselves in spiritual and physical terms has increased even more. However, when the urban transformation projects are put into practice, the needs and demands of the users are not taken into account; moreover, there are no studies showing the satisfaction or dissatisfaction of the users following the implementation. In the current study, satisfaction/dissatisfaction levels of the users were determined by asserting the user profile of Zağnos Valley, which is the first urban transformation area of Trabzon. In the valley, which is an important air corridor and a recreation area for Trabzon, questionnaires were implemented through face-to-face interview technique. Factor analysis was carried out in order to reveal the socio-demographic characteristics, space usage trends, and spatial usage characteristics of the users. In order to measure satisfaction and dissatisfaction levels, the determined criteria were weighted on a 5-point Likert scale and frequency distributions were examined. In this way, solution proposals have been made in order to increase the level of satisfaction and remediate the level of dissatisfaction of users.

Structure and electromagnetic properties of NiZn spinel ferrite with nano-sized ZnAl{sub 2}O{sub 4} additions

In this study, nanocrystalline ZnAl{sub 2}O{sub 4} (ZA) (x = 0–20 wt%) were introduced into Ni{sub 0.4}Zn{sub 0.6}Fe{sub 2}O{sub 4} ferrite (NZ) by a solid-state reaction method combining a sol–gel auto-combustion method. The effects of ZA addition on the crystalline phase formation, microstructures, magnetic and dielectric properties were systematically investigated. X-ray diffraction and scanning electron microscope results reveal that the added ZA can fully solve into the NZ to form a ceramic with single-phase cubic spinel structure, and the grain size decreases obviously as x > 5 wt%. Meanwhile, the magnetic and dielectric properties exhibit significantly dependent on the ZA addition content. With the increasing addition level of ZA from 0 to 20 wt%, the initial permeability μ{sub i} is found increased initially and then decreased with the maximum 679 at x = 0.5 wt%. For the samples with x ≤ 5 wt%, permittivity ε′ is relatively higher at low frequencies (ε′ = 91–138 at 1 MHz) and dielectric loss tan δ{sub ε} shows distinct peak behavior. When x reaches 10 wt%, however, the ε′ and tan δ{sub ε} show very stable spectra from 1 MHz to 1 GHz. - Highlights: • Various amount of nanocrystalline ZnAl{sub 2}O{sub 4} (ZA) were introduced into NiZn ferrite. • NiZn ferrite can form single-phase spinel ceramic materials with ZA additives. • ZA has significant effects on magnetic and dielectric properties of the ceramics. • It provides a new method for fabricating NiZn ferrite with tunable properties.

Direct antitumor effects of bisphosphonates (BPs) have been demonstrated in various cancer cells in vitro. However, the effective concentrations of BPs are typically much higher than their clinically relevant concentrations. Oral cancers frequently invade jawbone and may lead to the release of Ca(2+) in primary lesions. We investigated the effects of the combined application of zoledronic acid (ZA) and Ca(2+) on proliferation and apoptosis of oral cancer cells. Human oral cancer cells, breast cancer cells, and colon cancer cells were treated with ZA at a wide range of concentrations in different Ca(2+) concentration environments. Under a standard Ca(2+) concentration (0.6mM), micromolar concentrations of ZA were required to inhibit oral cancer cell proliferation. Increasing extracellular Ca(2+) concentrations greatly enhanced the potency of the ZA cytocidal effect. The ability of Ca(2+) to enhance the cytocidal effects of ZA was negated by the Ca(2+)-selective chelator EGTA. In contrast, the cytocidal effect of ZA was less pronounced in breast and colon cancer cells regardless of whether extracellular Ca(2+) was elevated. In oral cancer cells incubated with 1.6mM Ca(2+), ZA up-regulated mitochondrial Bax expression and increased mitochondrial Ca(2+) uptake. This was associated with decreased mitochondrial membrane potential and increased release of cytochrome c. We suggest that ZA can specifically produce potent cytocidal activity in oral cancer cells in an extracellular Ca(2+)-dependent manner, implying that BPs may be useful for treatment of oral squamous cell carcinoma with jawbone invasion leading to the hypercalcemic state.

To study the effects of zoledronic acid (ZA) on the vasculogenic mimicry of osteosarcoma cells in vitro. A Three-dimensional culture of LM8 osteosarcoma cells on a type I collagen matrix was used to investigate whether osteosarcoma cells can develop vasculogenic mimicry, and to determine the effects of ZA on this process. In addition, the cellular ultrastructural changes were observed using scanning electron microscopy and laser confocal microscopy. The effects of ZA on the translocation of RhoA protein from the cytosol to the membrane in LM8 cells were measured via immunoblotting. ZA inhibited the development of vasculogenic mimicry by the LM8 osteosarcoma cells, decreased microvilli formation on the cell surface, and disrupted the F-actin cytoskeleton. ZA prevented translocation of RhoA protein from the cytosol to the membrane in LM8 cells. ZA can impair RhoA membrane localization in LM8 cells, causing obvious changes in the ultrastructure of osteosarcoma cells and induce cell apoptosis, which may be one of the underlying mechanisms by which the agent inhibits the development of vasculogenic mimicry by the LM8 cells.

Influence of grain size on radiation damage of different steel types was investigated intensely during past few years. But the obtained data did not enable complete answer. The objective of here described experiments was to obtain new data about the influence of grain size on radiation hardening of the steel for reactor vessel fabrication. The steel was exposed to integral fast neutron flux bigger than 10{sup 19} n/cm{sup 2} and irradiation temperature less than 100 deg C. As a part of VISA-2/1 project these investigations we redone in cooperation with the CEN Saclay. Simultaneously, experimental procedures applied for obtaining samples with different grain sizes produced steels with different macrostructure. For that reason possible influence of microstructure should ne taken into account. In fact, it was found that the performance of samples depended more on microstructure than on the grain size. The most important results obtain from this experiments indicate the following: (1) samples with different grain size having ferrite-perlite structure showed the same tensile strength; (2) samples with cementite on the grain boundaries showed more intensive hardening after irradiation; (3) samples exposed to {gamma} radiation for obtaining bigger grains showed decreased hardening than samples deformed under room temperature and exposed to {alpha} radiation. Experiments were performed under 150 deg C. samples with ferrite-perlite microstructure showed further smaller increase of tensile limit and hardening. Uticaj velicine zrna na radijaciono otvrdnjavanje razlicitih tipova celika intenzivno je proucavan u toku poslednjih nekoliko godina. Medjutim, dobijeni podaci nisu omogucili da se u potpunosti odgovori na pitanje. Opisani eksperimenti imali su za cilj da pruze nove podatke o uticaju velicine zrna na radijaciono otvrdnjavanje date vrste celika za reaktorski sud, pri integralnom fluksu brzih neutrona > 10{sup 19} n/cm{sup 2} i temperaturi ozracivanja < 100 deg C.

Clinical studies using definitive-intent stereotactic radiation therapy (SRT) for the local treatment of canine osteosarcoma (OSA) have shown canine patients achieving similar median survival times as the current standard of care (amputation and adjuvant chemotherapy). Despite this, there remains an unacceptable high risk of pathologic fracture following radiation treatment. Zoledronic acid (ZA) and parathyroid hormone (PTH) are therapeutic candidates for decreasing this fracture risk post-irradiation. Due to differing mechanisms, we hypothesized that the combined treatment with ZA and PTH would significantly improve bone healing more than ZA or PTH treatment alone. Using an orthotopic model of canine osteosarcoma in athymic rats, we evaluated bone healing following clinically-relevant doses of radiation therapy (12 Gy x 3 fractions, 36 Gy total). Groups included 36 Gy SRT only, 36 Gy SRT plus ZA, 36 Gy SRT plus ZA and PTH, 36 Gy SRT plus PTH, and 36 Gy SRT plus localized PTH treatment. Our study showed significant increases in bone volume and increased polar moments of inertia (in the distal femoral metaphysis) 8 weeks after radiation in the combined (ZA/PTH) treatment group as compared to radiation treatment alone. Histomorphometric analysis revealed evidence of active mineralization at the study endpoint as well as successful tumor-cell kill across all treatment groups. This work provides further evidence for the expanding potential indications for ZA and PTH therapy, including post-irradiated bone disease due to osteosarcoma.

In vivo microcomputed tomography (micro-CT) images at 4 weeks showed significantly higher mineralized tissue volume (MV) in the intramedullary defect region and the neocortical/callus region...... in all GBM-treated groups. After euthanization at 8 weeks, ex vivo micro-CT showed that addition of ZA (GBM + ZA) and BMP-2 (GBM + ZA + BMP-2) mainly increased the neocortical and callus formation, with the highest MV in the combined ZA and BMP-2-treated group. Qualitative histological analysis......, verifying the increased neocortical/callus thickness and finding of trabecular bone in all GBM-treated groups, supported that the differences in MV measured with micro-CT in fact represented bone tissue.

RA research reacto was not operated due to the prohibition issued in 1984 by the Government of Serbia. Three major tasks were finished in order to fulfill the licensing regulations about safety of nuclear facilities which is the condition for obtaining permanent operation licence. These projects involved construction of the emergency cooling system, reconstruction of the existing special ventilation system, and renewal of the system for electric power supply of the reactor systems. Renewal of the RA reactor instrumentation system was initiated. Design project was done by the Russian Atomenergoeksport, and is foreseen to be completed by the end of 1988. The RA reactor safety report was finished in 1987. This annual report includes 8 annexes concerning reactor operation, activities of services and financial issues, and three special annexes: report on testing the emergency cooling system, report on renewal of the RA reactor and design specifications for reactor renewal and reconstruction.

Full Text Available Sea level change affects human living conditions, particularly ocean coasts. However, sea level change is still unclear along the Black Sea coast due to lack of in-situ measurements and low resolution satellite data. In this paper, sea level change along the Black Sea coast is investigated from joint satellite altimetry, tide gauge (TG and Global Positioning System (GPS observations. The linear trend and seasonal components of sea level change are estimated at 8 TG stations (Amasra, Igneada, Trabzon-II, Sinop, Sile, Poti, Tuapse, and Batumi located along the Black Sea coast, which are compared with Satellite Altimetry and GPS. At the tide gauge stations with long-term records such as Poti (about 21 years and Tuapse (about 19 years, the results obtained from the satellite altimetry and tide gauge observations show a remarkably good agreement. While some big differences are existed between Satellite Altimetry and TG at other stations, after adding vertical motion from GPS, correlation coefficients of the trend have been greatly improved from 0.37 to 0.99 at 3 co-located GPS and TG stations (Trabzon-II, Sinop and Sile.

V kamnolomu pridobivajo različne kamene agregate. Pridobivanje le teh poteka z mehanskim lomljenjem hribin. Ob potrebi večjih količin tehničnega kamenja za hitrejše pridobivanje uporabljajo kemično lomljenje z uporabo gospodarskih razstreliv. Razstreliva so kemične sestavine, ki ob detonaciji eksplodirajo. Poznamo več vrst gospodarskih razstreliv. Ena najvarnejših so emulzijska razstreliva. Za začetno detonacijo uporabljajo različna vžigalna sredstva. Najpogosteje uporabljena metoda je me...

Pojem prevare je težko opredeljiv, saj je odvisen od tega, iz katerega zornega kota prevaro opazujemo. Po standardih jih delimo na poslovodske in zaposlenske. Motive za nastanek prevare smo predstavili s trikotnikom prevar, ki razlaga, da posamezniki zagrešijo prevaro, ko so prisotni trije dejavniki: pritisk, priložnost in racionalizacija. Glavno odgovornost za preprečevanje in odkrivanje prevar nosi poslovodstvo, ki mora skrbeti za usmeritve in postopke, ki pomagajo dosegati kolikor mogoče p...

Full Text Available W artykule przedstawiono badania związane z optymalną alokacją środków do zwalczania rozlewów olejowych na morzu. Należą one do problemu logistycznego typu lokacja-alokacja (LA. W badaniach skoncentrowano się na statkach posiadanych przez polskie służby odpowiedzialne za rozlewy na Morzu Bałtyckim w tym SAR. Do optymalnej alokacji środków wykorzystano metodę dwustopniową, w której pierwszy stopień, wykonany za pomocą metod optymalizacji genetycznej, polegał na takim rozlokowaniu sił do zwalczania rozlewów, aby zminimalizować koszty dotarcia do rozlewu na morzu. W drugim etapie wykorzystano model symulacyjny rozlewu olejowego i akcji jego zwalczania do weryfikacji rozwiązań uzyskanych za pomocą algorytmu genetycznego.

Uvedba zahtev standarda PCI DSS je za banko, ki nudi storitve vezane na kartično poslovanje, obvezna. V minulih letih so banke investirale v kompleksne rešitve, s katerimi zagotavljajo visok nivo informacijske varnosti. Kljub temu standard PCI DSS v določenih zahtevah predstavlja dodatne varnostne ukrepe, ki jih morajo uvesti banke. V raziskovalnem delu smo izvedli analizo standarda PCI DSS, s katero smo ugotovili vidike, v katerih je standard šibek a so za učinkovito uvedbo varnostnih za...
