The full wave code OLGA, for determining the coupling of a single row lower hybrid launcher (waveguide grills) to the plasma, is extended to handle multirow multijunction active passive structures (like the C3 and C4 launchers on TORE SUPRA) by implementing the scattering matrix formalism. The extended code is still computationally fast because of the use of (i) 2D splines of the plasma surface admittance in the accessibility region of the k-space, (ii) high order Gaussian quadrature rules for the integration of the coupling elements and (iii) utilizing the symmetries of the coupling elements in the multiperiodic structures. The extended OLGA code is benchmarked against the ALOHA-1D, ALOHA-2D and TOPLHA codes for the coupling of the C3 and C4 TORE SUPRA launchers for several plasma configurations derived from reflectometry and interferometery. Unlike nearly all codes (except the ALOHA-1D code), OLGA does not require large computational resources and can be used for everyday usage in planning experimental runs. In particular, it is shown that the OLGA code correctly handles the coupling of the C3 and C4 launchers over a very wide range of plasma densities in front of the grill.

Santamaria et al. (Human Immunology 1993 37: 39-50) describe a method of sequence-based typing (SBT) for HLA-A, B and C alleles said to give "unambiguous typing of any sample, heterozygous or homozygous, without requiring additional typing information". From SBT analysis, which involves determination of partial sequences of mixed alleles, these investigators reported that cell lines KT17 (HLA-B35,62) and OLGA (HLA-B62) from the reference panel of the 10th International Histocompatibility Workshop express novel variants of HLA-B15 (B1501-MN6) and HLA-B35 (B3501-MN7) respectively. To study further the novel alleles, we cloned and sequenced full-length HLA-B cDNA clones isolated from the KT17 and OLGA cell lines. We find that KT17 expresses B*3501, as assigned by SBT, and B*1501, the common allele encoding the B62 antigen. We were unable to confirm that KT17 expresses the novel B1501-MN6 variant identified by SBT. For OLGA our analysis confirms the partial sequences obtained by SBT. Thus OLGA expresses B*1501 and a novel HLA-B allele. The complete sequence of the latter shows it is a hybrid having exons 1 and 2 in common with B*1501 and other B15 subtypes and exons 3-7 in common with B*3501 and related molecules including B*5301 and B*5801. The novel allele has been designated B*1520 because of its sequence similarity with the B15 group; furthermore, serological analysis shows that the B*1520 product does not express epitopes in common with either B35, B53 or B58. The B*1520 heavy chain has a similar isoelectric point to A*3101; B*1520 was undetected by previous applications of isoelectric focusing because B*1520 and A31 are both expressed by OLGA. In conclusion, HLA-B typing of two cell lines by cDNA cloning and sequencing gives concordant results with SBT for three of the four alleles. The cause of the discrepancy for the fourth allele is unknown, however, this finding indicates that the novel HLA-A, B and C sequences emerging from SBT studies need independent

Critical evaluation of mechanistic two-phase flow pipeline and well simulation models

Dhulesia, H.; Lopez, D.

1996-12-31

Mechanistic steady state simulation models, rather than empirical correlations, are used for a design of multiphase production system including well, pipeline and downstream installations. Among the available models, PEPITE, WELLSIM, OLGA, TACITE and TUFFP are widely used for this purpose and consequently, a critical evaluation of these models is needed. An extensive validation methodology is proposed which consists of two distinct steps: first to validate the hydrodynamic point model using the test loop data and, then to validate the over-all simulation model using the real pipelines and wells data. The test loop databank used in this analysis contains about 5952more » data sets originated from four different test loops and a majority of these data are obtained at high pressures (up to 90 bars) with real hydrocarbon fluids. Before performing the model evaluation, physical analysis of the test loops data is required to eliminate non-coherent data. The evaluation of these point models demonstrates that the TACITE and OLGA models can be applied to any configuration of pipes. The TACITE model performs better than the OLGA model because it uses the most appropriate closure laws from the literature validated on a large number of data. The comparison of predicted and measured pressure drop for various real pipelines and wells demonstrates that the TACITE model is a reliable tool.« less

Real Time Mud Gas Logging During Drilling of DFDP-2B

NASA Astrophysics Data System (ADS)

Mathewson, L. A.; Toy, V.; Menzies, C. D.; Zimmer, M.; Erzinger, J.; Niedermann, S.; Cox, S.

2015-12-01

The Deep Fault Drilling Project (DFDP) aims to improve our understanding of the Alpine Fault Zone, a tectonically active mature fault system in New Zealand known to rupture in large events, by deep scientific drilling. The borehole DFDP-2B approached the Alpine Fault at depth, reaching a final depth of 892 m (820 m true vertical depth). Online gas analysis (OLGA) while drilling tracked changes in the composition of gases extracted from the circulating drill mud. The composition of fluids from fault zones can provide information about their origins, flow rates and -paths, fluid-rock interactions along these paths, and the permeability structure of the faulted rock mass. Apart from an atmospheric input, the gases in drilling mud derive from the pore space of rock, crushed at the drill bit, and from permeable layers intersected by the borehole. The rapid formation of mud wall cake seals the borehole from further fluid inflow, hence formation-derived gases enter mostly at the depth of the drill bit. OLGA analyses N2, O2, Ar, CO2, CH4, He, and H2 on a mass spectrometer, hydrocarbons CH4, C2H6, C3H8, i-C4H10, and n-C4H10 on a gas chromatograph, and Rn using a lucas-cell detector. Gas was sampled for offline analyses on noble gas and stable isotopes to complement the OLGA dataset. The principle formation-derived gases found in drilling mud during drilling of DFDP-2 were CO2 and CH4, with smaller component of H2 and He2. High radon activity is interpreted to reflect intervals of active fluid flow through highly fractured and faulted rock. 3He/4He values in many samples were extremely air-contaminated, i.e. there was almost no excess of non-atmospheric He. The 3He/4He values measured at 236 m and 610 m, which are the only analyses with uncertainties <100%, are very similar to those measured in hot springs along the Alpine Fault, e.g. Fox River (0.64 Ra), Copland (0.42 Ra), Lower Wanganui (0.81 Ra). We will compare these data to those gathered using OLGA and discuss the

In several studies, different risk factors other than antibiotic resistance have been documented with Helicobacter pylori eradication failure. We aimed in this study to investigate the relationship of gastric density of H. pylori, the occurrence/degree of gastric atrophy, and intestinal metaplasia (IM) with success rate of H. pylori eradication. Two hundred consecutive treatment naive patients who received bismuth containing standart quadruple treatment due to H. pylori infection documented by histopathological examination of two antral or two corpal biopsies entered this retrospective study. The updated Sydney system was used to grade the activity of gastritis, density of H. pylori colonization, atrophy, and IM. Stages III and IV of operative link for gastritis assessment (OLGA) or the operative link on gastric intestinal metaplasia assessment (OLGIM) stages was considered as severe gastritis. H. pylori eradication was determined via stool H. pylori antigen test performed 4 weeks after the end of therapy. The presence of gastric atrophy and IM was significantly higher in patients with eradication failure (p = 0.001 and 0.01, respectively). Severe gastritis (OLGA III-IV and OLGIM III-IV) rates were higher in eradication failure group. A multiple linear regression analysis showed that OLGA and OLGIM stages were to be independent risk factors for eradication failure (p = 0.03 and 0.01, respectively). Our results suggested that histopathologically severe gastritis may cause H. pylori eradication failure. In addition, we found that H. pylori density was not a risk factor for treatment failure in patients who receive quadruple treatment.

Slug sizing/slug volume prediction, state of the art review and simulation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Burke, N.E.; Kashou, S.F.

1995-12-01

Slug flow is a flow pattern commonly encountered in offshore multiphase flowlines. It is characterized by an alternate flow of liquid slugs and gas pockets, resulting in an unsteady hydrodynamic behavior. All important design variables, such as slug length and slug frequency, liquid holdup, and pressure drop, vary with time and this makes the prediction of slug flow characteristics both difficult and challenging. This paper reviews the state of the art methods in slug catcher sizing and slug volume predictions. In addition, history matching of measured slug flow data is performed using the OLGA transient simulator. This paper reviews themore » design factors that impact slug catcher sizing during steady state, during transient, during pigging, and during operations under a process control system. The slug tracking option of the OLGA simulator is applied to predict the slug length and the slug volume during a field operation. This paper will also comment on the performance of common empirical slug prediction correlations.« less

Evaluating bump control techniques through convergence monitoring

DOE Office of Scientific and Technical Information (OSTI.GOV)

Campoli, A.A.

1987-07-01

A coal mine bump is the violent failure of a pillar or pillars due to overstress. Retreat coal mining concentrates stresses on the pillars directly outby gob areas, and the situation becomes critical when mining a coalbed encased in rigid associated strata. Bump control techniques employed by the Olga Mine, McDowell County, WV, were evaluated through convergence monitoring in a Bureau of Mines study. Olga uses a novel pillar splitting mining method to extract 55-ft by 70-ft chain pillars, under 1,100 to 1,550 ft of overburden. Three rows of pillars are mined simultaneously to soften the pillar line and reducemore » strain energy storage capacity. Localized stress reduction (destressing) techniques, auger drilling and shot firing, induced approximately 0.1 in. of roof-to-floor convergence in ''high'' -stress pillars near the gob line. Auger drilling of a ''low''-stress pillar located between two barrier pillars produced no convergence effects.« less

Gastritis is defined as inflammation of the gastric mucosa. In histological terms, it is distinguishable into two main categories, i.e. non-atrophic and atrophic. In the gastric mucosa, atrophy is defined as the loss of appropriate glands. There are several etiological types of gastritis, their different etiology being related to different clinical manifestations and pathological features. Atrophic gastritis (resulting mainly from long-standing Helicobacter pylori infection) is a major risk factor for the onset of (intestinal type) gastric cancer. The extent and site of the atrophic changes correlate significantly with the cancer risk. The current format for histology reporting in cases of gastritis fails to establish an immediate link between gastritis phenotype and risk of malignancy. Building on current knowledge of the biology of gastritis, an international group of pathologists [Operative Link for Gastritis Assessment (OLGA)] has proposed a system for reporting gastritis in terms of its stage (the OLGA Staging System): this system places the histological phenotypes of gastritis on a scale of progressively increasing gastric cancer risk, from the lowest (Stage 0) to the highest (Stage IV). The aim of this tutorial is to provide unequivocal information on how to standardize histology reports on gastritis in diagnostic practice.

Much less is known about the paleoclimate and paleoceanography of the North Pacific than the North Atlantic despite the North Pacific's important role in the global ocean-climate system. Kodiak Island lies in the northwestern Gulf of Alaska astride the eastern end of the Aleutian Low. On southwestern Kodiak Island, coastal bluffs section a series of moraines, kettle ponds, and bogs formed between 15 and 9 ka BP. Distinctive tephras from volcanoes on the Alaska Peninsula provide time-lines within the stratigraphy. Deformation events recorded in sediment stacks from basins within glaciotectonic landforms allows precise dating of glacial events. An ice capmore » occupied the Kodiak archipelago during the last glaciation. Three glacial advances of the southwestern margin of this ice cap occurred after 15 ka BP. At 13.4 ka, piedmont ice lobes formed large push moraines extending into Shelikof Strait during the Low Cape Advance. The less-extensive Tundra Advance culminated between 12 and 11.7 ka BP followed by glacier retreat then readvance to form the prominent Olga Moraine system between 11 and 10 ka BP. The timing of the Tundra and Olga Advances correlates closely with that of the Older and Younger Dryas cold episodes in northwestern Europe suggesting that these climatic oscillations were synchronous throughout the northern hemisphere.« less

ISS023-E-029806 (30 April 2010) --- Kata Tjuta, Australia is featured in this image photographed by an Expedition 23 crew member on the International Space Station. Located in the Northern Territory of Australia, Uluru – Kata Tjuta National Park hosts some of the world’s most spectacular examples of inselbergs, or isolated mountains. The most famous of these inselbergs is Uluru (also known as Ayers Rock). An equally massive inselberg located approximately 30 kilometers to the northwest is known as Kata Tjuta– like Uluru, this is a sacred site to the native Anangu or Aboriginal people. Explorers named the highest peak Mount Olga, with the entire grouping of rocks informally known as “the Olgas”. Mount Olga has a peak elevation of 1,069 meters above sea level, making it 206 meters higher than Uluru. Kata Tjuta is comprised of gently dipping Mount Currie Conglomerate, a sedimentary rock that includes abundant rounded fragments of other rock types (here, primarily granite with less abundant basalt and rhyolite) in a coarse sandy matrix. Geologists interpret the Mount Currie Conglomerate as a remnant of a large fan of material rapidly eroded from mountains uplifted approximately 550 million years ago. Subsequent burial under younger sediments consolidated the eroded materials to form the conglomerate exposed at the surface today. In this photograph, afternoon sunlight highlights the rounded summits of Kata Tjuta against the surrounding sandy plains. Sand dunes are visible at upper right; while in other areas (image top and image left) sediments washed from the rocks have been anchored by a variety of grasses and bushes adapted to the arid climate. Green vegetation in the ephemeral stream channels that drain Kata Tjuta (bottom center) provides colorful contrast with the red rocks and surrounding soils. Large gaps in the rocks (highlighted by shadows) are thought to be fractures that have been enlarged due to erosion.

Brown, T.S.; Clapham, J.; Danielson, T.J.

1996-12-31

A computer model has been developed which accurately describes transient heat transfer in pipeline bundles. An arbitrary number of internal pipelines containing different fluids, flowing in either direction along with the input of heat to one or more of the fluids can be accommodated. The model is coupled to the transient, multiphase flow simulator OLGA. The lines containing the multiphase production fluids are modeled by OLGA, and the heat transfer between the internal lines, carrier pipe, and surroundings is handled by the bundle model. The model has been applied extensively to the design of a subsea, heated bundle system formore » the Britannia gas condensate field in the North Sea. The 15-km bundle system contains a 14{double_prime} production line, an 8{double_prime} test line, a 3{double_prime} methanol line, and a 12{double_prime} internal heating medium line within a 37.25{double_prime} carrier. The heating medium (water) flows in the internal heating medium line and in the annulus at 82,500 BPD. The primary purpose of the bundle system is to avoid the formation of hydrates. A secondary purpose is to avoid the deposition of paraffin. The bundle model was used to (1) compare the merits of two coaxial lines vs. a single bundle; (2) optimize the insulation levels on the carrier and internal lines; (3) determine the minimum time required to heat up the bundle; (4) determine heat input requirements to avoid hydrates throughout the field life, (5) determine temperature profiles along the lines for a range of production rates; (6) study ruptures of the production line into the bundle annulus; (7) determine minimum temperatures during depressurization; and (8) determine cool-down times. The results of these studies were used to size lines, select insulation levels, assess erosion potential, design for thermal expansion-induced stresses, and to select materials of construction.« less

The chemical properties of element 106 (Seaborgium, Sg) were successfully studied using the On-line Gas Chromatography Apparatus (OLGA III). After chemical separation of Sg in the form of volatile oxichlorides the nuclides {sup 265}Sg and {sup 266}Sg were unambiguously identified and their half-lives were determined for the first time. The Sg nuclides were produced from the {sup 248}Cm({sup 22}Ne, 4,5n){sup 266,265}Sg reaction at the GSI Darmstadt UNILAC accelerator. Simultaneously, short-lived W nuclides were produced from a small admixture of {sup 152}Gd to the Cm target material. As predicted by relativistic calculations and by extrapolations of chemical properties, it was demonstratedmore » that Sg oxichlorides are indeed less volatile than their lighter homologue W- and Mo-oxichlorides.« less

The magnetic flux excess effect as a consequence of non-Parker radial evolution of interplanetary magnetic field

NASA Astrophysics Data System (ADS)

Khabarova, Olga

2015-04-01

The “magnetic flux excess” effect is exceeding of magnetic flux Fs=4π|Br|r2 measured by distant spacecraft over the values obtained through measurements at the Earth’s orbit (Owens et al., JGR, 2008). Theoretically, its conservation should take place at any heliocentric distance r further than 10 solar radii, which means that the difference between the flux measured at 1 AU and Fs observed in another point in the heliosphere should be zero. However, the difference is negative closer to the Sun and increasingly positive at larger heliocentric distances. Possible explanations of this effect are continuously discussed, but the consensus is yet not reached.It is shown that a possible source of this effect is the solar wind expansion not accordingly with the Parker solution at least at low heliolatitudes. The difference between the experimentally found (r-5/3) and commonly used (r-2) radial dependence of the radial component of the IMF Br may lead to mistakes in the IMF point-to-point recalculations (Khabarova & Obridko, ApJ, 2012; Khabarova, Astronomy Reports, 2013). Using the observed Br (r) dependence, it is easy to find the variation of difference between the magnetic flux Fs(r) at certain heliocentric distance r and Fs_1AU at 1 AU, which can be calculated as Fs(r)-Fs_1AU =4π·(B1AU /[1AU]-5/3) (r2-5/3 -[1AU]2-5/3) (Khabarova, Astronomy Reports, 2013).The possible influence of presence of the heliospheric current sheet near the ecliptic plane on the picture of magnetic field lines and consequent deviation from the Parker's model is discussed.- Khabarova Olga, and Obridko Vladimir, Puzzles of the Interplanetary Magnetic Field in the Inner Heliosphere, 2012, Astrophysical Journal, 761, 2, 82, doi:10.1088/0004-637X/761/2/82, http://arxiv.org/pdf/1204.6672v2.pdf- Olga V.

The pressing need for educated nursing staff in Greece was first recognized by Queen Olga and Crown Princess Sofia, at the end of the nineteenth century with significant international aid.As a result, the School of Nursing Sisters of the Sanatorium "Evangelismos" was founded in 1875 and the first Greek "School of Certified Nurses" of the "Saint Sophia" Children's Hospital was established in 1897. This Children's Hospital has provided Greece with excellent trained nurses in Pediatric as well as Neonatal and Infant Nursing ever since. Distinguished nurses from abroad as well as a plethora of professors and physicians have taught at the school which has effectively made a mark in forming a tradition until today. The international concept of the school, including enhancing the young nurses' practice with experience from abroad is one of its most interesting features. The first Greek nursing schools rank among the first in the world.

Australian Red Dune Sand: A Potential Martian Regolith Analog

NASA Technical Reports Server (NTRS)

Kuhlman, K. R.; Marshall, J.; Evans, N. D.; Luttge, A.

2001-01-01

To demonstrate the potential scientific and technical merits of in situ microscopy on Mars, we analyzed a possible Martian regolith analog - an acolian red dune sand from the central Australian desert (near Mt. Olga). This sand was chosen for its ubiquitous red coating and the desert environment in which is it found. Grains of this sand were analyzed using a variety of microanalytical techniques. A database of detailed studies of such terrestrial analogs would assist the study of geological and astrobiological specimens in future missions to Mars. Potential instrument concepts for in situ deployment on Mars include local electrode atom probe nanoanalysis (LEAP), vertical scanning white light interferometry (VSWLI), scanning electron microscopies, energy dispersive x-ray microanalysis (EDX), atomic force microscopy (AFM) and X-ray diffraction (XRD). While in situ deployment of these techniques is many years away, ground-based studies using these analytical techniques extend our understanding of the data obtained from instruments to be flown in the near future.

Slug-sizing/slug-volume prediction: State of the art review and simulation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Burke, N.E.; Kashou, S.F.

1996-08-01

Slug flow is a flow pattern commonly encountered in offshore multiphase flowlines. It is characterized by an alternate flow of liquid slugs and gas pockets, resulting in an unsteady hydrodynamic behavior. All important design variables, such as slug length and slug frequency, liquid holdup, and pressure drop, vary with time and this makes the prediction of slug flow characteristics both difficult and challenging. This paper reviews the state of the art methods in slug-catcher sizing and slug-volume predictions. In addition, history matching of measured slug flow data is performed using the OLGA transient simulator. This paper reviews the design factorsmore » that impact slug-catcher sizing during steady state, during transient, during pigging, and during operations under a process-control system. The slug-tracking option of the simulator is applied to predict the slug length and the slug volume during a field operation. This paper will also comment on the performance of common empirical slug-prediction correlations.« less

The site of investigation, oasis Kharga, is located at about 600 km south of Cairo, Egypt; Baris is about 90 km from Kharga also to south and towards more inside the desert. The work was aimed to investigate the rock mass stability at Baris and to estimate the water intake in the Oasis Kharga. A controlled source electromagnetic (CSEM) approach developed earlier by IGF UB RAS (Geophysical Federal Institute, Ural Branch of Russian Academy of Science) is applied to image the ranked deformation levels in the massive structure of the Baris. The wide profile system of observation has been used to monitor the three components of the alternating magnetic field along predefined measuring lines in the study area. Here we can show the first results that we shall continue during some cycles of monitoring. The second part of our work was linked with mapping the massif structure inside the oasis City, where only using our device we could construct the geoelectrical sections for 5 profiles and show the real structure of the water volume and its complicated structure up to 200 meters depth recording the values of real not apparent resistivity. The analytical treatments provided good information about the structure of the rock massive and its rank of degradation, the lateral distribution of the geotechnical heterogeneity, and finally a conclusive outcome about foundation stability. We can conclude that the general dynamic state close to the destruction level within the investigation areas is getting worse over the time; this is reflected in the crack's densities and positions, also on the changes in the lateral distribution of geoelectrical heterogeneity as an indicator of the saturation of the surface rock in the study area with water [1,2].

Shallow water sea slugs (Gastropoda: Heterobranchia) from the northwestern coast of the Sea of Japan, north of Peter the Great Bay, Russia

PubMed Central

2016-01-01

The coast of northern Primorye region, north of Peter the Great Bay has been sparsely studied in regards to its molluscan fauna, with just a few works reviewing the distribution of local mollusks. This work presents a survey of the shallow water heterobranch sea slugs currently occurring around Kievka Bay to Oprichnik Bay, Russia. Thirty-nine species of sea slugs were found in this study and the new species Cadlina olgae sp. nov., described herein. Most (24) of the species occurring in the area have widespread ranges in the northern Pacific Ocean. The eight species are endemic for the Sea of Japan and adjacent part of the Sea of Okhotsk. Seven other occur also in northern Atlantic and Arctic waters. Thirteen found species are not known from Peter the Great Bay but known from adjacent northern Pacific waters. The finding of a previously undescribed species emphasizes the need of further surveys, particularly in subtidal and deeper waters, in order to improve the knowledge on this neglected fauna in Primorye.

Analysis of the interplanetary magnetic field observations at different heliocentric distances

NASA Astrophysics Data System (ADS)

Khabarova, Olga

2013-04-01

Multi-spacecraft measurements of the interplanetary magnetic field (IMF) from 0.29 AU to 5 AU along the ecliptic plane have demonstrated systematic deviations of the observed IMF strength from the values predicted on the basis of the Parker-like radial extension models (Khabarova, Obridko, 2012). In particular, it was found that the radial IMF component |Br| decreases with a heliocentric distance r with a slope of -5/3 (instead of r-2 expansion law). The current investigation of multi-point observations continues the analysis of the IMF (and, especially, Br) large-scale behaviour, including its latitudinal distribution. Additionally, examples of the mismatches between the expected IMF characteristics and observations at smaller scales are discussed. It is shown that the observed effects may be explained by not complete IMF freezing-in to the solar wind plasma. This research was supported by the Russian Fund of Basic Researches' grants Nos.11-02-00259-a, and 12-02-10008-K.

Grass, David; Jasinski, Michael F.; Govere, John

2003-01-01

There has been increasing effort in recent years to employ satellite remotely sensed data to identify and map vector habitat and malaria transmission risk in data sparse environments. In the current investigation, available satellite and other land surface climatology data products are employed in short-term forecasting of infection rates in the Mpumalanga Province of South Africa, using a multivariate autoregressive approach. The climatology variables include precipitation, air temperature and other land surface states computed by the Off-line Land-Surface Global Assimilation System (OLGA) including soil moisture and surface evaporation. Satellite data products include the Normalized Difference Vegetation Index (NDVI) and other forcing data used in the Goddard Earth Observing System (GEOS-1) model. Predictions are compared to long- term monthly records of clinical and microscopic diagnoses. The approach addresses the high degree of short-term autocorrelation in the disease and weather time series. The resulting model is able to predict 11 of the 13 months that were classified as high risk during the validation period, indicating the utility of applying antecedent climatic variables to the prediction of malaria incidence for the Mpumalanga Province.

Bacteriol. 87:852–862. 1964.—Ergothioneine and hercynine were found to be synthesized by a wide variety of mycobacteria grown in chemically defined media free from these compounds. The cultures examined included 53 recently isolated and laboratory strains of Mycobacterium tuberculosis, 26 “unclassified” mycobacteria (Runyon groups I to IV), and representatives of most other species in the genus. Purification and separation of the betaines was achieved by means of chromatography on two successive alumina columns. Photometric measurement of the diazotized effluents from the second column permitted amounts of each compound to be determined. Measurement of hercynine by this method was made possible for the first time by the development of a standard curve. The pathway of ergothioneine biosynthesis in mycobacteria, as judged by the use S35-sulfate and l-histidine-2-C14 as tracers, appears similar to that found in Neurospora crassa and Claviceps purpurea, that is, from histidine to ergothioneine via hercynine. None of a small group of bacteria other than mycobacteria was found to produce ergothioneine. Two strains of group A streptococci and one of Escherichia coli produced hercyninelike material, as yet unidentified. PMID:14137624

Unlike its general-purpose contemporaries -- TACITE, OLGA, Traflow (OGJ, Jan. 3, 1994, p. 42; OGJ, Jan. 10, 1994, p. 52), and PLAC (AEA Technology, U.K.) -- ABASs is a dedicated software for slow transient flows generated during pigging operations in the Duyong network, offshore Malaysia. This network links the Duyong and Bekok fields to the onshore gas terminal (OGT) on the east coast of peninsular Malaysia. It predictsmore » the steady-state pressure drop vs. flow rates, condensate volume in the network, pigging dynamics including volume of produced slug, and the condensate build-up following pigging. The predictions of ABASs have been verified against field data obtained from the Duyong network. Presented here is an overview of the development, verification, and application of the ABASs software. Field data are presented for verification of the software, and several operational scenarios are simulated using the software.

This study of the urban heat island (UHI) aims to support planning authorities by going beyond the traditional way of urban heat island studies. Therefore, air temperature as well as the physiologically equivalent temperature (PET) were applied to take into account the effect of the thermal atmosphere on city dwellers. The analysis of the urban heat island phenomenon of Stuttgart, Germany, includes a long-term frequency analysis using data of four urban and one rural meteorological stations. A (high resolution map) of the UHI intensity and PET was created using stepwise multiple linear regression based on data of car traverses as well as spatial data. The mapped conditions were classified according to the long-term frequency analysis. Regarding climate change, the need for adaptation measures as urban greening is obvious. Therefore, a spatial analysis of quantification of two scenarios of a chosen study area was done by the application of a micro-scale model. The nocturnal UHI of Stuttgart is during 15 % stronger than 4 K in the city center during summer when daytime heat stress occurs during 40 %. A typical summer condition is mapped using statistical approach to point out the most strained areas in Stuttgart center and west. According to the model results, the increase in number of trees in a chosen area (Olga hospital) can decrease PET by 0.5 K at 22:00 CET but by maximum 27 K at 14:00 CET.

Morphological descriptions of seven free-living nematode species from hydrothermal sites of the Mid-Atlantic Ridge are presented. Four of them are new for science: Paracanthonchus olgae sp. n. (Chromadorida, Cyatholaimidae), Prochromadora helenae sp. n. (Chromadorida, Chromadoridae), Prochaetosoma ventriverruca sp. n. (Desmodorida, Draconematidae) and Leptolaimus hydrothermalis sp. n. (Plectida, Leptolaimidae). Two species have been previously recorded in hydrothermal habitats, and one species is recorded for the first time in such an environment. Oncholaimus scanicus (Enoplida, Oncholaimidae) was formerly known from only the type locality in non-hydrothermal shallow milieu of the Norway Sea. O. scanicus is a very abundant species in Menez Gwen, Lucky Strike and Lost City hydrothermal sites, and population of the last locality differs from other two in some morphometric characteristics. Desmodora marci (Desmodorida, Desmodoridae) was previously known from other remote deep-sea hydrothermal localities in south-western and north-eastern Pacific. Halomonhystera vandoverae (Monhysterida, Monhysteridae) was described and repeatedly found in mass in Snake Pit hydrothermal site. The whole hydrothermal nematode assemblages are featured by low diversity in comparison with either shelf or deep-sea non-hydrothermal communities. The nematode species list of the Atlantic hydrothermal vents consists of representatives of common shallow-water genera; the new species are also related to some shelf species. On the average, the hydrothermal species differ from those of slope and abyssal plains of comparable depths by larger sizes, diversity of buccal structures, presence of food content in the gut and ripe eggs in uteri.

At present, few organisms are known to and capable of naturally producing laccases and white rot fungi are one such group. In the present study, three fungal species, namely, Ganoderma lucidum -CDBT1 , Ganoderma japonicum, and Lentinula edodes , isolated from their native habitat in Nepal were screened for laccase production, and G. lucidum -CDBT1 was found to express highest levels of enzyme (day 10 culture media showed 0.92 IU/mg total protein or 92 IU/mL laccase activity with ABTS as substrate). Lignin extracted from rice straw was used in Olga medium for laccase production and isolation from G. lucidum -CDBT1. Presence of lignin (5 g/L) and copper sulfate (30  μ M) in the media increased the extracellular laccase content by 111% and 114%, respectively. The laccase enzyme produced by G. lucidum -CDBT1 was fractionated by ammonium sulfate and purified by DEAE Sepharose anion exchange chromatography. The purified enzyme was found to have a molecular mass of 43 kDa and exhibits optimal activity at pH 5.0 and 30°C. The isolated laccase was thermally stable for up to 70°C for 1 h and exhibited broad pH stability. The kinetic constants, K m , V max , and K cat , determined using 2,2'-azinobis-(-3-ethylbenzothiazoline-6-sulfonic acid) as substrate were found to be 110  μ M, 36  μ mol/min/mg, and 246 min -1 , respectively. The isolated thermostable laccase will be used in future experiments for delignification process.

Gastric cancer continues to be an important healthcare problem from a global perspective. Most of the cases in the Western world are diagnosed at late stages when the treatment is largely ineffective. Helicobacter pylori (H. pylori) infection is a well-established carcinogen for gastric cancer. While lifestyle factors are important, the efficacy of interventions in their modification, as in the use of antioxidant supplements, is unconvincing. No organized screening programs can be found outside Asia (Japan and South Korea). Although several screening approaches have been proposed, including indirect atrophy detection by measuring pepsinogen in the circulation, none of them have so far been implemented, and more study data is required to justify any implementation. Mass eradication of H. pylori in high-risk areas tends to be cost-effective, but its adverse effects and resistance remain a concern. Searches for new screening biomarkers, including microRNA and cancer-autoantibody panels, as well as detection of volatile organic compounds in the breath, are in progress. Endoscopy with a proper biopsy follow-up remains the standard for early detection of cancer and related premalignant lesions. At the same time, new advanced high-resolution endoscopic technologies are showing promising results with respect to diagnosing mucosal lesions visually and targeting each biopsy. New histological risk stratifications (classifications), including OLGA and OLGIM, have recently been developed. This review addresses the current means for gastric cancer primary and secondary prevention, the available and emerging methods for screening, and new developments in endoscopic detection of early lesions of the stomach.

Helicobacter pylori secretory peptidyl prolyl isomerase, HP0175, is progressively identified as a pro-inflammatory and pro-carcinogenic protein, which serves to link H. pylori infection to its more severe clinical outcomes. Here, we have analyzed host HP0175-specific antibody responses in relation to the severity of gastritis. The HP0175 gene fragment was PCR-amplified, cloned, expressed and purified by Ni-NTA affinity chromatography. Serum antigen-specific antibody responses of non-ulcer dyspeptic patients (N = 176) against recombinant HP0175 were detected by western blotting. The infection status of these subjects was determined by rapid urease test, culture, histology, and serology. The grade of inflammation and stage of atrophy were scored blindly according to the OLGA staging system. The recombinant HP0175 (rHP0175) was expressed as a ~35 kDa protein and its identity was confirmed by western blotting using anti-6X His tag antibody and pooled H. pylori-positive sera. Serum IgG antibodies against rHP0175 segregated our patients into two similar-sized groups of sero-positives (90/176, 51.1 %) and sero-negatives (86/176, 48.9 %). The former presented with higher grades of gastric inflammation (OR = 4.4, 95 % CI = 1.9-9.9, P = 0.001) and stages of gastric atrophy (OR = 18.3, 95 %CI = 1.4-246.6, P = 0.028). Our findings lend further support to the pro-inflammatory nature of H. pylori peptidyl prolyl isomerase (HP0175) and recommends this antigen as a non-invasive serum biomarker of the severity of H. pylori-associated gastritis.

Enhancements of Tow-Steering Design Techniques: Design of Rectangular Panel Under Combined Loads

An extension to existing design tools that utilize tow-steering is presented which is used to investigate the use of elastic tailoring for a flat panel with a central hole under combined loads of compression and shear. The elastic tailoring is characterized by tow-steering within individual lamina as well as a novel approach based on selective reinforcement, which attempts to minimize compliance through the use of Cellular Automata design concepts. The selective reinforcement designs lack any consideration of manufacturing constraints, so a new tow-steered path definition was developed to translate the prototype selective reinforcement designs into manufacturable plies. The minimum weight design of a flat panel under combined loading was based on a model provided by NASA-Langley personnel and analyzed by STAGS within the OLGA design environment. Baseline designs using traditional straight fiber plies were generated, as well as tow-steered designs which incorporated parallel, tow-drop, and overlap plies within the laminate. These results indicated that the overlap method provided the best improvement with regards to weight and performance as compared to traditional constant stiffness monocoque panels, though the laminates did not measure up to similar designs from the literature using sandwich and isogrid constructions. Further design studies were conducted using various numbers of the selective reinforcement plies at the core and outer surface of the laminate. None of these configurations exhibited notable advantages with regard to weight or buckling performance. This was due to the fact that the minimization of the compliance tended to direct the major stresses toward the center of the panel, which decreased the ability of the structure to withstand loads leading to instability.

Influence of Terrestrial Weathering on the Magnetic Record of a LL Chondrite

Kohout, T.; Kletetschka, G.; Wasilewski, P.

2001-12-01

The origin of our solar system may have been accompanied by transient energetic events capable of magnetizing the materials from which the solid bodies in the solar system formed. The magnetic field associated with some of some of these events should have been recorded by the magnetic mineralogy contained within meteorites. To extract this information from meteorites many noise components must be carefully eliminated. The fusion crust has long been established as restricted to a thin layer on the surface of meteorite. Magnetic screening of the fusion crust that relates to Murchison meteorite indicates that during the entry and landing at least 6 mm thick layer is affected by terrestrial TRM acquisition. Many of the meteorite finds have long term residence in the terrestrial oxidized environment. This weathering is the subject of this study. The meteorite in question landed in the Libya stony desert and has obvious surface weathering that can be referred to as desert varnish. The consequent iron oxide mineralization introduced very stable origin of very stable chemical remanent magnetization. The magnetic remanence in fragments without the desert varnish is between 20 - 50 % of the oxidized ones. The orientation of this CRM appears to be random indicating that the sample may have rotated during the long period of aeolian transport and varnish formation. Magnetization of the white matrix samples (20 - 50 % of weathered ones) is thermally more stable and also randomly oriented. The range of NRM/SIRM values for both mineralogies varies between 10-2 and 10-3.

2014-05-01

Online monitoring and sampling of drill mud gas (OLGA) was conducted during standard rotary drilling and core drilling of the INFLUINS borehole EF-FB 1/12 to gain information on the composition of gases and their distribution at depth within the Thuringian Syncline (Germany). The method can help to identify areas of enhanced permeability and/or porosity, open fractures, and other strata associated with gases at depth. The gas-loaded drill mud was continuously degassed in a modified gas-water separator, which was installed in the mud ditch in close distance to the drill mud outlet. The extracted gas phase was pumped in a nearby field laboratory for continuous on-line analysis. First information on the gas composition (H2, He, N2, O2, CO2, CH4, Ar, Kr) was available only few minutes after gas extraction. More than 40 gas samples were taken from the gas line during drilling and pumping tests for further laboratory studies. Enhanced concentration of methane, helium, hydrogen and carbon dioxide were detected in drill mud when the drill hole encountered gas-rich strata. Down to a depth of 620 m, the drill mud contained maximum concentration of 55 ppmv He, 1400 ppmv of CH4, 400 ppmv of hydrogen and 1.1 vol-% of CO2. The drilling mud gas composition is linked with the drilled strata. Buntsandstein and Muschelkalk show different formation gas composition and are therefore hydraulically separated. Except for helium, the overall abundance of formation gases in drilling mud is relatively low. We therefore consider the INFLUINS borehole to be dry. The correlation between hydrogen and helium and the relatively high helium abundance rules out any artificial origin of hydrogen and suggest a radiolytic origin of hydrogen. Values CH4/(C2H6/C3H8)

The site of investigation, 15th May city, is a new suburb of Helwan, at about 35 km south of Cairo, Egypt. The work is aimed to investigate the rock mass stability at "Quarter 27" in 15th May City, which is linked with cracks formation into the buildings. A controlled source electromagnetic (CSEM) approach developed earlier by IGF UB RAS (Geophysical Federal Institute, Ural Branch of Russian Academy of Science) is applied to image the ranked deformation levels in the massive structure. The wide profile system of observation has been used to monitor the three components of the alternating magnetic field along predefined measuring lines in the study area. Four cycles of observation have been carried out in 2008, 2010, 2011, and 2012. The acquired data sets have been subjected to analytical processing procedure to estimate the changes in the geotechnical parameters during the time of these four cycles of observation. The analytical treatments provided good information about the structure of the rock massive and its rank of degradation, the lateral distribution of the geotechnical heterogeneity, and finally a conclusive outcome about foundation stability. We conclude that the general dynamic state close to the destruction level within the investigation area is getting worse over the time; this is reflected in the crack's densities and positions, also on the changes in the lateral distribution of geoelectric heterogeneity as an indicator of the saturation of the surface rock in the study area with water [1].

Five new species of small grass cicadas belonging to the genus Graminitigrina Ewart and Marques are described, together with detailed analyses of their calling songs. Four species occur in Queensland, G. aurora n. sp. from eastern central Queensland near Fairbairn Dam; G. flindensis n. sp. from central Queensland between Hughenden northwards for at least 108 km; G. einasleighi n. sp. from near The Lynd, Einasleigh River, northeastern Queensland; G. selwynensis n. sp. from the Selwyn Range, northwestern Queensland, at locations about 40 km east of Mount Isa and 25 km southwest of Cloncurry, this latter here transferred from G. bowensis Ewart and Marques; G. uluruensis n. sp. from Uluru and the Olgas in southwestern Northern Territory, extending northwards through Tennant Creek and apparently further north to near Larrimah, a linear distance of approximately 1190 km. These new species bring the known Graminitigrina species to ten, all superficially similar in colour and morphology. A key to male specimens is provided for the 10 species. Additional distribution records and additional aural song recordings are presented for G. bowensis, these requiring the transfer of populations previously identified as G. bowensis from Croydon and Georgetown, northern Gulf region, to G. karumbae Ewart and Marques. Detailed comparative analyses, including NMDS analyses, of the songs of all 10 species are provided, which show that the song parameters are appropriate to distinguish the species, although some partial overlap is noted in the waveform plots between the songs of G. uluruensis n. sp. and G. flindensis n. sp. Regional variations of song parameters are noted in the calling songs of most of the species described.

Access and success with less: improving productivity in broad-access postsecondary institutions.

PubMed

Jenkins, Davis; Rodríguez, Olga

Achieving national goals for increased college completion in a time of scarce resources will require the postsecondary institutions that enroll the majority of undergraduates--community colleges and less-selective public universities--to graduate more students at a lower cost. Davis Jenkins and Olga Rodriguez examine research on how these "broad-access" institutions can do so without sacrificing access or quality. Research indicates that the strategies broad-access institutions have relied on in the past to cut costs--using part-time instructors and increasing student-faculty ratios--may in fact reduce productivity and efficiency. The limited evidence available suggests that some of the most popular strategies for improving student success are not cost-effective. New strategies to cut costs and improve college success are therefore imperative. Some believe that redesigning courses to make use of instructional technologies will lead to better outcomes at lower cost, although the evidence is mixed. Recently, a growing number of institutions are going beyond redesigning courses and instead changing the way they organize programs and supports along the student's "pathway" through college. These efforts are promising, but their effects on cost per completion are not yet certain. Meager funding has so far hampered efforts by policy makers to fund colleges based on outcomes rather than how many students they enroll, but some states are beginning to increase the share of appropriations tied to outcomes. Jenkins and Rodriquez argue that as policy makers push colleges to lower the cost per graduate, they must avoid providing incentives to lower academic standards. They encourage policy makers to capitalize on recent research on the economic value of postsecondary education to measure quality, and urge colleges and universities to redouble efforts to define learning outcomes and measure student mastery.

MN112: a new Galactic candidate luminous blue variable

We report the discovery of a new Galactic candidate luminous blue variable (cLBV) via detection of an infrared circular nebula and follow-up spectroscopy of its central star. The nebula, MN112, is one of many dozens of circular nebulae detected at 24μm in the Spitzer Space Telescope archival data, whose morphology is similar to that of nebulae associated with known (c)LBVs and related evolved massive stars. Specifically, the core-halo morphology of MN112 bears a striking resemblance to the circumstellar nebula associated with the Galactic cLBV GAL079.29+00.46, which suggests that both nebulae might have a similar origin and that the central star of MN112 is an LBV. The spectroscopy of the central star showed that its spectrum is almost identical to that of the bona fide LBV PCygni, which also supports the LBV classification of the object. To further constrain the nature of MN112, we searched for signatures of possible high-amplitude (>~1mag) photometric variability of the central star using archival and newly obtained photometric data covering a 45-yr period. We found that the B magnitude of the star was constant within error margins, while in the I band the star brightened by ~=0.4mag during the last 17 yr. Although the non-detection of large photometric variability leads us to use the prefix `candidate' in the classification of MN112, we remind the readers that the long-term photometric stability is not unusual for genuine LBVs and that the brightness of PCygni remained relatively stable during the last three centuries.

Gas phase chromatography using The Heavy Element Volatility Instrument (HEVI) and the On Line Gas Apparatus (OLGA III) was used to determine volatilities of ZrBr 4, HfBr 4, RfBr 4, NbBr 5, TaOBr 3, HaCl 5, WBr 6, FrBr, and BiBr 3. Short-lived isotopes of Zr, Hf, Rf, Nb, Ta, Ha, W, and Bi were produced via compound nucleus reactions at the 88-Inch Cyclotron at Lawrence Berkeley National Laboratory and transported to the experimental apparatus using a He gas transport system. The isotopes were halogenated, separated from the other reaction products, and their volatilities determined by isothermal gas phase chromatography.more » Adsorption Enthalpy (ΔH a) values for these compounds were calculated using a Monte Carlo simulation program modeling the gas phase chromatography column. All bromides showed lower volatility than molecules of similar molecular structures formed as chlorides, but followed similar trends by central element. Tantalum was observed to form the oxybromide, analogous to the formation of the oxychloride under the same conditions. For the group 4 elements, the following order in volatility and ΔH a was observed: RfBr 4 > ZrBr 4 > HfBr 4. The ΔH a values determined for the group 4, 5, and 6 halides are in general agreement with other experimental data and theoretical predictions. Preliminary experiments were performed on Me-bromides. A new measurement of the half-life of 261Rf was performed. 261Rf was produced via the 248Cm( 18O, 5n) reaction and observed with a half-life of 74 -6 +7 seconds, in excellent agreement with the previous measurement of 78 -6 +11 seconds. We recommend a new half-life of 75±7 seconds for 261Rf based on these two measurements. Preliminary studies in transforming HEVI from an isothermal (constant temperature) gas phase chromatography instrument to a thermochromatographic (variable temperature) instrument have been completed. Thermochromatography is a technique that can be used to study the volatility and ΔH a of longer

Olga Petrivna Chepinoga, doctor of science (biology), senior scientific worker, was born on July 1, 1907, in Kyiv. She graduated from the 1st Kyiv Medical Institute (1927-1931). In 1931-1935 she worked at various medical institutions of Ukraine. In 1935 O. P. Chepinoga was employed by the Institute of Biochemistry of the National Academy of Sciences of the Ukr.SSR as a laborant, then as an assistant, junior and senior scientific worker. In 1940 O. P. Chepinoga defended a thesis for a Candidate's degree, and from 1941 she was given a rank of the senior scientific worker. During the Great Patriotic War she served in the armed forces of the Soviet Army (1941-1945) as a medical officer in the rank of captain. In 1944-1963 she worked at the Instutute of Biochemistry of the AS of the Ukr.SSR as a senior scientific worker, and in 1963-1965 headed the Laboratory of Nucleic Acids. In 1952 O. P. Chepinoga defended a thesis for Doctor's degree in biology On Biologic Role of Nucleic Acids. Investigations of O. P. Chepinoga were first devoted to oxidation processes in muscles in various physiologic conditions, physico-chemical properties of myosin and its ATPase activity. Since 1948 her scientific interests had been concentrating on studying the biologic role and metabolism of nucleic acids, their transformation in the organism in norm and in pathological states. She was the first to find that various proteins interacted with DNA molecule. The highest activity of DNAse and RNAse was revealed in the organs which permanently synthesize proteins (liver, spleen, pancreas). Under quantitative undifferentiated growth of malignant tumors (Brown-Pierse carcinoma and Crocker sarcoma) the great part belongs to the process of DNA disintegrations; DNAse activity increases considerably in the animal and human blood that is not observed at other somatic diseases and is of great diagnostic value. Considerable shifts in DNAse activity at various pathologies were not found. The enrichment of

Rising cost pressure due to the implementation of the DRG-System and quality assurance lead to an increased use of therapy standards and standard operating procedures (SOPs) in intensive care medicine. The intention of the German Scientific Society supported project "OLGA" (Online Guideline Assist) is to develop a prototype of a knowledge based system supporting physicians of an intensive care unit in recognizing the indication for and selecting a specific guideline or SOP. While the response of the prototype on user entries can be displayed as a signal on the used workstation itself, the location and time for a reminder of scheduled or missed procedures or reactions to imported information is a difficult issue. One possible approach to this task is the display of non acknowledged reminders or recommendations while logging on to a system. The objective of this study is to analyse user behaviour of the physicians working on the surgical intensive care unit to decide whether the login authentication is a sufficient trigger for clinical reminding. The surgical intensive care unit examined in this study comprises 14 beds. Medical care is provided by physicians working in shifts 24 hours a day, 7 days a week, with two anaesthetists at a time and an additional senior consultant during daytime. The entire documentation (examinations, medication, orders, care) is performed using the patient data management system ICUData. The authentication process of the physicians was logged and analysed. Throughout the observation period from December 13th 2005 to January 11th 2006 3563 physician logins were counted in total. The mean span between logins was in 11.3 minutes (SD 14.4), the median 7 minutes. The 75% centile was 14 minutes, the 95% centile 38 min. Intervals greater than 60 minutes occurred in 75%, and greater than 90 minutes in 25% of the days. It seems reasonable that reminders sent during authentication are able to enforce workflow compliance. It is possible to send

During low-flow periods, salty water from the tidal part of the Caloosahatchee River moves upstream during boat lockages at the W. P. Franklin Darn near Ft. Myers, Florida, as shown on figure L Salty water enters the lock chamber through openings of the downstream sector gates which separate tidal and fresh water; when the upstream gates open, some of the salty water moves into the upper pool, probably as a density current. Repeated injections of salty water cause a progressive increase in the salinity of the upstream water. The salty water moves upstream within the deeper parts of the river channel as far as 5 or more miles above the lock. Some mixing of the high-chloride deeper water and the fresher shallow water occurs in the affected reach above the lock, probably as a result of wind and waves, and turbulence created by boat traffic.

On Thursday the 6th of November a round table was organised at the Centre of Architectural and Urban Studies of the "Ion Mincu" University of Architecture and Urban Planning on the topic of this session. It included a review of the previous editions, and an outlook to the edition this year. We shared publications, and a publication is in work from the round table itself. The series of round tables at the Centre of Architectural and Urban Studies is an innitiative of Constantin Hostiuc, the secretary general of the centre. This round table was organised by Maria Bostenaru Dan, and moderated by Cristina Olga Gociman, who currently runs a project on a related topic. From the various ways to approach the effects of hazards, up to the disatrous ones, on urban areas, we consider the most suitable the approach to the impact. From the point of view of natural sciences and of the engineering ones this was approached a number of times, and newly social sciences are included as well. The role of planning and design for a better prevention, and even post-disaster intervention is ignored many times though. The goal of the round table was to bring together multidisciplinary approaches (architecture, urban planning, seismology, geography, structural engineering, ecology, communication sciences, art history) on a problem set from this point of view. Discussed topics were: 1. Assessment and mapping methods of the impact of natural hazards on urban areas (preventive, postdisaster) 2. Visualisation and communication techniques of the assessed impact, including GIS, internet, 3D 3. Strategies for the reduction of the impact of natural hazards on urban areas 4. Suitable methods of urban design for the mitigation of the effects of disasters in multihazard case 5. Partnership models among the involved actors in the decision process for disaster mitigaton 6. Urban planning instruments for risc management strategies (ex. master plan) 7. Lessons learned from the relationship between hazard

The presently known most neutron-rich isotopes of element 106 (seaborgium, Sg), {sup 265}Sg and {sup 266}Sg, were produced in the fusion reaction {sup 22}Ne+{sup 248}Cm at beam energies of 121 and 123 MeV. Using the On-Line Gas chemistry Apparatus OLGA, a continuous separation of Sg was achieved within a few seconds. Final products were assayed by {alpha}-particle and spontaneous fission (SF) spectrometry. {sup 265}Sg and {sup 266}Sg were identified by observing time correlated {alpha}-{alpha}-({alpha}) and {alpha}-SF decay chains. A total of 13 correlated decay chains of {sup 265}Sg (with an estimated number of 2.8 random correlations) and 3 decay chainsmore » of {sup 266}Sg (0.6 random correlations) were identified. Deduced decay properties were T{sub 1/2}=7.4{sub {minus}2.7}{sup +3.3} s (68{percent} c.i.) and E{sub {alpha}}=8.69 MeV (8{percent}), 8.76 MeV (23{percent}), 8.84 MeV (46{percent}), and 8.94 MeV (23{percent}) for {sup 265}Sg; and T{sub 1/2}=21{sub {minus}12}{sup +20} s (68{percent} c.i.) and E{sub {alpha}}=8.52 MeV (33{percent}) and 8.77 MeV (66{percent}) for {sup 266}Sg. The resolution of the detectors was between 50{endash}100 keV (full width at half maximum). Upper limits for SF of {le}35{percent} and {le}82{percent} were established for {sup 265}Sg and {sup 266}Sg, respectively. The upper limits for SF are given with a 16{percent} error probability. Using the lower error limits of the half-lives of {sup 265}Sg and {sup 266}Sg, the resulting lower limits for the partial SF half-lives are T{sub 1/2}{sup SF}({sup 265}Sg){ge}13 s and T{sub 1/2}{sup SF}({sup 266}Sg){ge}11 s. Correspondingly, the partial {alpha}-decay half-lives are between T{sub 1/2}{sup {alpha}}({sup 265}Sg)=4.7{endash}16.5 s (68{percent} c.i.) and T{sub 1/2}{sup {alpha}}({sup 266}Sg)=9{endash}228 s (68{percent} c.i.), using the upper and lower error limits of the half-lives of {sup 265}Sg and {sup 266}Sg.

The working group for this topic was formed by David Delepine, Lorenzo Díaz, Gerardo Herrera and Olga Félix Beltrán. The three topics included invited talks dedicated to reviewing theoretical and experimental aspects of the corresponding topic. We had also plenary topical sessions during the mornings and early afternoons and parallel thematic sessions were held late in the afternoons. The reviews sessions were delivered by invited speakers of international prestige on the corresponding subjects and having an active collaboration with the Mexican scientific community. The plenary topical sessions and parallel thematic sessions were given by active researchers both from abroad and working in México. The program included also a permanent poster session and the organizing committee awarded the best poster - a decision made by the three working groups - with a silver medal. On Sunday 23 October, we had an excursion to the ancient archaeological site of Plazuelas near Penjamo (Guanajuato). Plazuelas is a prehispanic archaeological site located just north of San Juan el Alto, some 2.7 kilometers north of federal highway 90 (Penjamo-Guadalajara), and about 11 kilometers west of the city of Penjamo in the state of Guanajuato, Mexico. The site has been recently opened to the public. This site is a very complex city, it was edified following the natural landscape surrounding it. This city was occupied between 600 and 900 a.C. After spending some time at this very interesting archaeological site, we went to Hacienda Corralejo, an hacienda where Tequila Corralejo is produced and we had a guided visit of the 'Tequilera' where the famous Corralejo blue bottle of Tequila is made. Hacienda Corralejo is very close to the orginal Hacienda where Miguel Hidalgo (a Mexican independence hero) was born which now

A Long-Term Space Astrophysics Research Program: The Evolution of the Quasar Continuum

Four papers have been written. One reports on the major study funded by this grant: a pan-chromatic study of the quasar continuum at redshift 3. Two others make use of the quasar continuum shapes to find the minimum total accretion luminosity of the Universe, and hence the efficiency and spin of supermassive black holes; the second shows that the reemission of absorbed quasar radiation alleviates a major problem with galaxy formation and the FIR background. The last paper recognizes the role quasars may play in the initial formation of dust in the early Universe. The major study of a sample of z=3 and its comparison with a sample of z=0.l quasars across the whole X-ray to radio spectrum was completed and accepted for publication in ApJ Supplements. This study comprises the thesis work of Olga Kuhn. The two samples are matched in evolved luminosity, and so should be sampling the same black hole population at different z, and in different accretion states. Despite this no strong differences were found between the samples, except in the 'small bump' region of the optical/UV. This region is dominated by FeII emission, and may indicate abundance evolution in quasars. The lack of overall spectral changes argues strongly against a single population of quasars fading over cosmic time, and for a multiple generation, or multiple outburst model for quasars. A study of the total luminosity absorbed from quasars and re-emitted in the infrared produced two results (reported in two papers): The minimum intrinsic luminosity/Gpc(3) from AGN compared with the measured mass density in supermassive black holes [Gpc(-3)] requires a conversion efficiency of accreted mass into luminosity of greater than 15%. Non-rotating black holes cannot exceed 5% efficiency, while rapidly rotating black holes can reach 47%. Hence our result requires that most supermassive black holes must be rapidly rotating. The second result comes from considering the contribution that the re-radiated quasar

For men, difficulties in communicating with their partner about the infertility increased the probability of terminating the treatment (OR 2.3, 95% CI 1.2-4.1) and, for women, frequent conflicts with their partner increased the probability of terminating the treatment (OR 12.4, 95% CI 2.9-54.1). For women, conflicts with friends were also a predictor of treatment termination (OR 2.2, 95% CI 1.2-4.2). Functional aspects of social relations have an impact on the decision to terminate fertility treatment among men and women. The findings in this study provide new insights into how the close social environment can have implications for men and women going through fertility treatment.

Carbon isotopes ratios of specific sugar compounds such as sucrose, raffinose, fructose, ribose and pinitol in needle and wood samples will help to evaluate the impact of drought on the carbohydrate balance and carbon allocation. Analyzing the oxygen isotopic compositions of soil water, sap water (water in branches) and precipitation we will determine the role of the different water sources for tree growth under drought conditions. The proposed work will provide a unique opportunity to assess the survival potential of mountain pine and larch trees exposed to drought that will help to estimate risks of modern climatic changes and forest damage.

Segregated Methods for Two-Fluid Models

Prosperetti, Andrea; Sundaresan, Sankaran; Pannala, Sreekanth

The previous chapter, with its direct simulation of the fluid flow and a modeling approach to the particle phase, may be seen as a transition between the methods for a fully resolved simulation described in the first part of this book and those for a coarse grained description based on the averaging approach described in chapter ??. We now turn to the latter, which in practice are the only methods able to deal with the complex flows encountered in most situations of practical interest such as fluidized beds, pipelines, energy generation, sediment transport, and others. This chapter and the nextmore » one are devoted to numerical methods for so-called two-fluid models in which the phases are treated as inter-penetrating continua describing, e.g., a liquid and a gas, or a fluid and a suspended solid phase. These models can be extended to deal with more than two continua and, then, the denomination multi-fluid models might be more appropriate. For example, the commercial code OLGA (Bendiksen et al. 1991), widely used in the oil industry, recognizes three phases, all treated as interpenetrating continua: a continuous liquid, a gas, and a disperse liquid phase present as drops suspended in the gas phase. The more recent PeTra (Petroleum Transport, Larsen et al. 1997) also describes three phases, gas, oil, and water. Recent approaches to the description of complex boiling flows recognize four inter-penetrating phases: a liquid phase present both as a continuum and as a dispersion of droplets, and a gas/vapor phase also present as a continuum and a dispersion of bubbles. Methods for these multi-fluid models are based on those developed for the two-fluid model to which we limit ourselves. In principle, one could simply take the model equations, discretize them, and solve them by a method suitable for non-linear problems, e.g. Newton-Raphson iteration. In practice, the computational cost of such a frontal attack is nearly always prohibitive in terms of storage requirement

In patients aged 70 years and older, ECT was associated with a decreased rate of dementia (0·68, 95% CI 0·58-0·80; p<0·0001), but in the propensity-score matched sample the HR was attenuated (0·77, 0·59-1·00; p=0·062). 31 754 patients (17·6%) died during follow-up (mortality rate per 1000 person-years 35·7, 95% CI 35·3-36·2) and supplementary analyses suggested that the risk of dementia, taking the competing mortality risk into account, was not significantly associated with ECT (subdistribution HR 0·98, 95% CI 0·76-1·26; p=0·24). ECT was not associated with risk of incidental dementia in patients with affective disorders after correcting for the potential effect of patient selection or competing mortality. The findings from this study support the continued use of ECT in patients with severe episodes of mood disorders, including those who are elderly.

Leaves and samples of recent wood of Eucalyptus species were collected along a rainfall gradient parallel to the coast of Western Australia between Perth in the north and Walpole in the south and along a southwest to northeast transect from Walpole in southwestern Australia, to near Mount Olga in central Australia. The collection included 65 species of Eucalyptus sampled at 73 sites and many of the species were collected at several sites along the rainfall gradient. Specific leaf area (SLA) and isotopic ratio of 13C to 12C (delta 13C) of leaves that grew in 2002, and tree ring growth and delta 13C of individual cell layers of the wood were measured. Rainfall data were obtained from the Australian Bureau of Meteorology for 29 locations that represented one or a few closely located collection sites. Site-averaged data and species-specific values of delta 13C decreased with decreasing annual rainfall between 1200 and 300 mm at a rate of 1.63 per thousand per 1000 mm decrease in rainfall. Responses became variable in the low rainfall region (< 300 mm), with some species showing decreasing delta 13C with rainfall, whereas delta 13C increased or remained constant in other species. The range of delta 13C values in the low rainfall region was as large as the range observed at sites receiving > 300 mm of annual rainfall. Specific leaf area varied between 2 and 6 m2 kg(-1) and tended to increase with decreasing annual rainfall in some species, but not all, whereas delta 13C decreased with SLA. The relationship between delta 13C and SLA was highly species and soil-type specific. Leaf-area-based nitrogen (N) content varied between 2 and almost 6 g m(-2) and decreased with rainfall. Thus, thicker leaves were associated with higher N content and this compensated for the effect of drought on delta 13C. Nitrogen content was also related to soil type and species identity. Based on a linear mixed model, statistical analysis of the whole data set showed that 27% of the variation in

the outline, partners divided work equally and began to carefully summarize. Groups summaries were edited, not only within groups, but also by other groups, in order to acquire a different perspective. Finally, Mr. Howard, our Biology II instructor, took a final look at the products before sending them off for the final review by Argonne. The final project was a 16-page pamphlet. The students reacted positively to the project. Asked if she was glad that she chose to work on the Argonne project, Katie Hanson said, 'Yes. I have enjoyed having the opportunity to become a published author. Also, it is an honor to be able to work with a prestigious, nationally recognized laboratory such as Argonne'. There were difficult aspects as well. Student Olga Zagariya said the hardest part of the project was 'trying to choose which information to put in the summary and which information to leave out, because it all seemed to be important'. It seems that everyone was satisfied with his or her section.« less

become pregnant and this may affect estimates of recurrence risk. In any case, calculating recurrence risk for newborns following siblings with the CA in question will probably no longer work (maybe it never worked) since the desire to reach a given family size depends on many factors, including the perceived risk of a CA. Access to prenatal diagnostic data may therefore well produce data closer to recurrence risk than data recorded at the time of birth. Pediatrics and Perinatal Epidemiology recently published a series of papers initiated by Olga Basso (3, 4) addressing in part the problem of moving from time scale one (starting at conception) to time scale two (starting at birth). Part of the addressed problems relate to a lack of options for starting observations on causal factors at the onset of exposure or, at best, before exposure. If that exposure happens early in fetal life, outcomes will be complicated by fetal deaths that probably end observation for ≥30% of subjects. That equals mortality rates we see for ≥95-year-olds or equals a cumulative death risk seen for newborns from birth to ≥65 years of age. If the exposure of interest is related to fetal death that opens up for strong collider stratification bias and selection when we condition on survival in our analyses for observations at the beginning of the second time scale (5). A negative association on that time scale need not reflect "prevention" in any sense other than suicides early in life will prevent later cancer deaths. It is difficult to imagine a counterfactual comparison to an exposed had he/she not been exposed and had survived fetal life. Those who were susceptible did not all survive. If we study fetal programming of adult diseases, we have to "condition on birth" in our studies, but we should be aware of the selection bias that follows. Fetal medicine will in many ways produce better data or data we never have had before, but it will change the conditions in many aspects of reproductive
