    One of main features in sensor networks is the function that processes real time state information after gathering needed data from many domains. The component technologies consisting of each node called a sensor node that are including physical sensors, processors, actuators and power have advanced significantly over the last decade. Thanks to the advanced technology, over time sensor networks have been adopted in an all-round industry sensing physical phenomenon. However, sensor nodes in sensor networks are considerably constrained because with their energy and memory resources they have a very limited ability to process any information compared to conventional computer systems. Thus query processing over the nodes should be constrained because of their limitations. Due to the problems, the join operations in sensor networks are typically processed in a distributed manner over a set of nodes and have been studied. By way of example while simple queries, such as select and aggregate queries, in sensor networks have been addressed in the literature, the processing of join queries in sensor networks remains to be investigated. Therefore, in this paper, we propose and describe an Incremental Join Algorithm (IJA) in Sensor Networks to reduce the overhead caused by moving a join pair to the final join node or to minimize the communication cost that is the main consumer of the battery when processing the distributed queries in sensor networks environments. At the same time, the simulation result shows that the proposed IJA algorithm significantly reduces the number of bytes to be moved to join nodes compared to the popular synopsis join algorithm.

    Helicobacter pylori (H pylori) gastritis presents a risk of cancer related to atrophy and intestinal metaplasia. Two recent classifications OLGA (Operative Link on Gastritis Assessment) and OLGIM (Operative Link on Gastritic Intestinal Metaplasia assessment) have been proposed to identify high-risk forms (stages III and IV). The aim of this study is to evaluate the OLGA and OLGIM staging systems in H pylori gastritis. A descriptive study of 100 cases of chronic H pylori gastritis was performed. The revaluation of Sydney System parameters of atrophy and intestinal metaplasia, of gastric antrum and corpus, allowed identifying respectively the stages of OLGA and OLGIM systems. The progressive risk of our H pylori gastritis was 6% according to OLGA staging and 7% according to OLGIM staging. Significant correlation was revealed between age and OLGA staging. High-risk gastritis according to OLGIM staging was significantly associated with moderate to severe atrophy. High-risk forms according to OLGA staging were associated in 80% of the cases to intestinal metaplasia. OLGA and OLGIM systems showed a highly significant positive correlation between them with a mismatch at 5% for H pylori gastritis. The OLGA and OLGIM staging systems in addition to Sydney System, allow selection of high risk forms of chronic gastritis requiring accurate observation.

    Atrophic gastritis remains a difficult histopathological diagnosis with low interobserver agreement. The aim of our study was to compare gastritis staging and interobserver agreement between general and expert gastrointestinal (GI) pathologists using Operative Link for Gastritis Assessment (OLGA) and Operative Link on Gastric Intestinal Metaplasia (OLGIM). We enrolled 835 patients undergoing upper endoscopy in the study. Two general and two expert gastrointestinal pathologists graded biopsy specimens according to the Sydney classification, and the stage of gastritis was assessed by OLGA and OLGIM system. Using OLGA, 280 (33.4 %) patients had gastritis (stage I-IV), whereas with OLGIM this was 167 (19.9 %). OLGA stage III- IV gastritis was observed in 25 patients, whereas by OLGIM stage III-IV was found in 23 patients. Interobserver agreement between expert GI pathologists for atrophy in the antrum, incisura angularis, and corpus was moderate (kappa = 0.53, 0.57 and 0.41, respectively, p < 0.0001), but almost perfect for intestinal metaplasia (kappa = 0.82, 0.80 and 0.81, respectively, p < 0.0001). However, interobserver agreement between general pathologists was poor for atrophy, but moderate for intestinal metaplasia. OLGIM staging provided the highest interobserver agreement, but a substantial proportion of potentially high-risk individuals would be missed if only OLGIM staging is applied. Therefore, we recommend to use a combination of OLGA and OLGIM for staging of chronic gastritis.

    La gastrite chronique à Helicobacter pylori (H pylori) présente un risque de cancérisation en rapport avec l'atrophie et la métaplasie intestinale. Deux nouvelles classifications, OLGA (Operative Link on Gastritis Assessment) et OLGIM (Operative Link on Gastritic Intestinal Metaplasia assessment) ont été proposées pour individualiser les formes à haut risque évolutif (stades III et IV). Le but de ce travail est d’évaluer les classifications de OLGA et de OLGIM au cours des gastrites chroniques à H pylori. Nous avons réalisé une étude descriptive transversale portant sur 100 cas de gastrite chronique à H pylori. La réévaluation des paramètres du Sydney System de l'atrophie et de la métaplasie intestinale, de l'antre et du corps gastrique, a permis de définir respectivement les stades OLGA et OLGIM. Le risque évolutif de nos gastrites à H pylori était de 6% selon OLGA et de 7% selon OLGIM. Une liaison significative a été révélée entre l’âge et OLGA. Les gastrites à haut risque selon OLGIM, étaient significativement associées à une atrophie modérée à sévère. Les formes à haut risque selon OLGA s'associaient dans plus de 80% des cas à une métaplasie intestinale. OLGA et OLGIM présentaient une corrélation positive et hautement significative entre elles avec une discordance évaluée à 5%. Les classifications de OLGA et OLGIM, en complément au Sydney System, permettent de sélectionner les formes de gastrites à haut risque nécessitant une surveillance étroite. PMID:27200133

    Land surface hydrology for the Off-line Land-surface GEOS Analysis (OLGA) system and Goddard Earth Observing System (GEOS-1) Data Assimilation System (DAS) has been examined using a river routing model. The GEOS-1 DAS land-surface parameterization is very simple, using an energy balance prediction of surface temperature and prescribed soil water. OLGA uses near-surface atmospheric data from the GEOS-1 DAS to drive a more comprehensive parameterization of the land-surface physics. The two global systems are evaluated using a global river routing model. The river routing model uses climatologic surface runoff from each system to simulate the river discharge from global river basins, which can be compared to climatologic river discharge. Due to the soil hydrology, the OLGA system shows a general improvement in the simulation of river discharge compared to the GEOS-1 DAS. Snowmelt processes included in OLGA also have a positive effect on the annual cycle of river discharge and source runoff. Preliminary tests of a coupled land-atmosphere model indicate improvements to the hydrologic cycle compared to the uncoupled system. The river routing model has provided a useful tool in the evaluation of the GCM hydrologic cycle, and has helped quantify the influence of the more advanced land surface model.

    Introducción: el carcinoma gástrico ocasiona al año unas 700 000 muertes en el mundo. El objetivo de este artículo es evaluar la atrofia en la mucosa vecina al adenocarcinoma gástrico tipo intestinal comparando los sistemas Sídney y OLGA. Diferencias en el rendimiento diagnóstico impulsarían el empleo de alguno. Métodos: estudiamos 28 sujetos con adenocarcinoma gástrico tipo intestinal (Lauren), que comparamos con 32 casos sin neoplasia, ambos grupos con gastrectomía total. Dos patólogos evaluaron la atrofia en el epitelio de cuerpo y antro no neoplásico con los sistemas Sídney y OLGA. Se obtuvieron la media, mediana y distribución de frecuencias por escala de medición, así como la distribución de las variables del estudio. Se calculó la sensibilidad, especificidad y los valores predictivos para cáncer gástrico gracias a dicotomizar las escalas con resultado positivo y negativo para atrofia avanzada. Resultados: veinticuatro de 28 casos con adenocarcinoma gástrico tipo intestinal mostraron atrofia avanzada con OLGA con una sensibilidad y especificidad de 77 y 85 % respectivamente. Con el sistema Sídney, 4 de 28 mostraron atrofia avanzada con una sensibilidad y especificidad de 14 y 100 % respectivamente. Conclusiones: el sistema OLGA tiene elevada sensibilidad y especificidad (77 y 85 % respectivamente) para reconocer cambios preneoplásicos en la mucosa vecina al cáncer gástrico. Empero, OLGA no mostró atrofia avanzada en adenomas foveolares con displasia de alto grado, ni en adenocarcinomas en las porciones proximales del estómago.

    In the present work the qualitative and quantitative analysis of Amaryllidaceae-type alkaloids in the aerial parts and bulbs of Galanthus reginae-olgae Orph. subsp. vernalis Kamari is presented for the first time using GC-MS analysis. The alkaloids galanthamine, lycorine, and tazettine were identified in both extracts while crinine and neronine were found only in the bulbs. The yield of alkaloid fraction from bulbs (36.8%) is very high compared to the yield from aerial parts (9.34%). Lycorine was the major component in both fractions. The antioxidant potential was determined by three complementary methods. The preparations to reduce the stable free radical DPPH to the yellow-colored 1,1-diphenyl-2-picrylhydrazyl with IC(50) values of 39 and 29 mug/mL for MeOH extracts from aerial parts and bulbs, respectively. The higher activity was given by EtOAc fraction of aerial parts with IC(50) of 10 mug/mL. This activity is probably due to the presence in EtOAc fraction of polar compounds such as polyphenols. The fraction exhibited a significant antioxidant capacity also in the beta-carotene-linoleic acid test system. A higher level of antioxidant activity was observed for EtOAc fraction from bulbs with IC(50) of 10 mug/mL after 30 min and 9 mug/mL after 60 min of incubation. In contrast, the fraction from bulbs performed poorly in the lipid peroxidation liposomes assay. Significant activity was obtained for dichloromethane fraction from aerial parts (IC(50) of 74 mug/mL). The major abundance of alkaloid in dichloromethane fraction may be responsible of the bulbs anti-cholinesterase highest activity (38.5%) at 0.5 mg/mL.

    The electrical energy consumption of battery-operated screwdrivers, which are widely used in many industries, e.g. automotive, heavy, chemical, etc., can be considerably reduced. This would allow increasing the service life of a battery and reducing the time of its charging, thus increasing the productivity and decreasing the prime cost of this battery. It is shown that up to 17.9% of electrical energy could be saved at assembling fixed threaded joints by removing power from the screwdriver immediately after reaching the required tightening torque.

    We found evidence that spontaneous self-assembly of DNA molecules from yolk granules occurred during the very early stage of egg fertilization. In order to find solid evidence for self-assembly of DNA molecules, we collected many available data in different stages of fertilized eggs, making a data table. At first by using acridine orange vital staining to demonstrate DNA, we noticed that some yolk granules emitted DNA signals that gradually increased with increasing incubation time from very small sizes to much larger nucleus-like structures. For convincing evidence, we also used another vital dye, Hoechst 33258 DNA-specific dye, to trace the changes in the yolk granules. The patterns of the DNA signals from yolk granules stained with Hoechst 33258 were the same as those from the yolk granules stained with acridine orange. A partial phase contrast microscopic image of the changes in the yolk granules showed some liquid-like material around the granules before the formation of the nucleus-like structures. Concomitant use of fluorescence and partial phase contrast microscopy suggested that these liquid-like materials may have been released from yolk granules in which spontaneous self-assembly of DNA molecules had occurred. Finally, in order to verify whether the DNA signals came from real DNA molecules or not, by using deoxyribonuclease I (DNAse), we confirmed that the nucleus-like structures were really assembled DNA molecules. Thus, in this article, we report evidence for the self-assembly of DNA molecules toward cell-like structures and discuss our findings, comparing them with those in the works of other pioneers, especially Antoine Béchamp, Olga Lepeshinskaya and Bong Han Kim, who insisted on the existence of a mitosis-free alternative pathway for generating new cells.

    The present study aimed to examine the controlling variables for initiating joint attention (IJA) in three children with autism. During the baseline, target objects were presented in a location where the child could see them, but the adult could not, and the emergence of IJA was assessed. Children with autism showed some IJA skills during the baseline, but none initiated pointing. In training, the motivating operation for IJA was manipulated by using each child's preferred materials as targets of joint attention. It was found that more frequent and functional joint attention behaviors were emitted following training. The present study suggests that difficulties in IJA in children with autism could be partly explained by restricted interests in children with autism.

    Frequency of high-level (showing/pointing) and low-level (coordinated gaze shifts) behaviors on the Early Social Communication Scales are often used as a measure of joint attention initiations (IJA). This study examined the degree to which these skills and response to joint attention (RJA; e.g. gaze following) were differentially related to measures of language and imitation in 53 children with autism spectrum disorder between the ages of 22 and 93 months. High-level and low-level IJA were not associated with each other, and only high-level IJA was associated with RJA, and language and imitation measures. High-level IJA and RJA were unique predictors of imitation, while RJA was a unique predictor of language. Findings indicate that IJA involves distinct skills, with high-level behaviors more closely related to social-communication skills.

  18. A frontotemporoparietal network common to initiating and responding to joint attention bids.

    Joint attention is a fundamental cognitive ability that supports daily interpersonal relationships and communication. The Parallel Distributed Processing model (PDPM) postulates that responding to (RJA) and initiating (IJA) joint attention are predominantly supported by posterior-parietal and frontal regions respectively. It also argues that these neural networks integrate during development, supporting the parallel processes of self- and other-attention representation during interactions. However, direct evidence for the PDPM is limited due to a lack of ecologically valid experimental paradigms that can capture both RJA and IJA. Building on existing interactive approaches, we developed a virtual reality paradigm where participants engaged in an online interaction to complete a cooperative task. By including tightly controlled baseline conditions to remove activity associated with non-social task demands, we were able to directly contrast the neural correlates of RJA and IJA to determine whether these processes are supported by common brain regions. Both RJA and IJA activated broad frontotemporoparietal networks. Critically, a conjunction analysis identified that a subset of these regions were common to both RJA and IJA. This right-lateralised network included the dorsal portion of the middle frontal gyrus (MFG), inferior frontal gyrus (IFG), middle temporal gyrus (MTG), precentral gyrus, posterior superior temporal sulcus (pSTS), temporoparietal junction (TPJ) and precuneus. Additional activation was observed in this network for IJA relative to RJA at MFG, IFG, TPJ and precuneus. This is the first imaging study to directly investigate the neural correlates common to RJA and IJA engagement, and thus support the assumption that a broad integrated network underlies the parallel aspects of both initiating and responding to joint attention.

  4. A test of flushing procedures to control salt-water intrusion at the W. P. Franklin Dam near Ft. Myers, Florida and The magnitude and extent of salt-water contamination in the Caloosahatchee River between La Belle and Olga, Florida

    USGS Publications Warehouse

    1970-01-01

    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.

    1998-08-01

    In the preceding paper (``On-line Gibbs Learning. I. General Theory'') we have presented the on-line Gibbs algorithm (OLGA) and studied analytically its asymptotic convergence. In this paper we apply OLGA to on-line supervised learning in several network architectures: a single-layer perceptron, two-layer committee machine, and a winner-takes-all (WTA) classifier. The behavior of OLGA for a single-layer perceptron is studied both analytically and numerically for a variety of rules: a realizable perceptron rule, a perceptron rule corrupted by output and input noise, and a rule generated by a committee machine. The two-layer committee machine is studied numerically for the cases of learning a realizable rule as well as a rule that is corrupted by output noise. The WTA network is studied numerically for the case of a realizable rule. The asymptotic results reported in this paper agree with the predictions of the general theory of OLGA presented in paper I. In all the studied cases, OLGA converges to a set of weights that minimizes the generalization error. When the learning rate is chosen as a power law with an optimal power, OLGA converges with a power law that is the same as that of batch learning.

  9. Res-E Support Policies in the Baltic States: Electricity Price Aspect (Part II)

    Bobinaite, V.; Priedite, I.

    2015-04-01

    Increasing volumes of electricity derived from renewable energy sources (RES-E) affect the electricity market prices and the prices for final electricity consumers in the Baltic States. The results of a multivariate regression analysis show that in 2013 the RES-E contributed to decreasing the electricity market prices in the Baltic States. However, the final electricity consumers pay for the promotion of RES-E through the approved RES-E component which has a tendency to increase. It is estimated that in 2013 the net benefits from the wind electricity promotion were achieved in Lithuania and Latvia while the net cost - in Estonia. This suggests that the economic efficiency of the wind electricity support scheme based on the application of feed-in tariffs was higher than that based on the feed-in premium.

  10. Dopaminergic variants in siblings at high risk for autism: Associations with initiating joint attention.

    Younger siblings of children with autism spectrum disorder (ASD; high-risk siblings) exhibit lower levels of initiating joint attention (IJA; sharing an object or experience with a social partner through gaze and/or gesture) than low-risk siblings of children without ASD. However, high-risk siblings also exhibit substantial variability in this domain. The neurotransmitter dopamine is linked to brain areas associated with reward, motivation, and attention, and common dopaminergic variants have been associated with attention difficulties. We examined whether these common dopaminergic variants, DRD4 and DRD2, explain variability in IJA in high-risk (n = 55) and low-risk (n = 38) siblings. IJA was assessed in the first year during a semi-structured interaction with an examiner. DRD4 and DRD2 genotypes were coded according to associated dopaminergic functioning to create a gene score, with higher scores indicating more genotypes associated with less efficient dopaminergic functioning. Higher dopamine gene scores (indicative of less efficient dopaminergic functioning) were associated with lower levels of IJA in the first year for high-risk siblings, while the opposite pattern emerged in low-risk siblings. Findings suggest differential susceptibility-IJA was differentially associated with dopaminergic functioning depending on familial ASD risk. Understanding genes linked to ASD-relevant behaviors in high-risk siblings will aid in early identification of children at greatest risk for difficulties in these behavioral domains, facilitating targeted prevention and intervention.

  11. Comparison of Surface Ground Temperature from Satellite Observations and the Off-Line Land Surface GEOS Assimilation System

    NASA Technical Reports Server (NTRS)

    The surface ground temperature (Tg) is an important meteorological variable, because it represents an integrated thermal state of the land surface determined by a complex surface energy budget. Furthermore, Tg affects both the surface sensible and latent heat fluxes. Through these fluxes. the surface budget is coupled with the atmosphere above. Accurate Tg data are useful for estimating the surface radiation budget and fluxes, as well as soil moisture. Tg is not included in conventional synoptical weather station reports. Currently, satellites provide Tg estimates globally. It is necessary to carefully consider appropriate methods of using these satellite data in a data assimilation system. Recently, an Off-line Land surface GEOS Assimilation (OLGA) system was implemented at the Data Assimilation Office at NASA-GSFC. One of the goals of OLGA is to assimilate satellite-derived Tg data. Prior to the Tg assimilation, a thorough investigation of satellite- and model-derived Tg, including error estimates, is required. In this study we examine the Tg from the n Project (ISCCP DI) data and the OLGA simulations. The ISCCP data used here are 3-hourly DI data (2.5x2.5 degree resolution) for 1992 summer months (June, July, and August) and winter months (January and February). The model Tg for the same periods were generated by OLGA. The forcing data for this OLGA 1992 simulation were generated from the GEOS-1 Data Assimilation System (DAS) at Data Assimilation Office NASA-GSFC. We examine the discrepancies between ISCCP and OLGA Tg with a focus on its spatial and temporal characteristics, particularly on the diurnal cycle. The error statistics in both data sets, including bias, will be estimated. The impact of surface properties, including vegetation cover and type, topography, etc, on the discrepancies will be addressed.

  4. White matter integrity, hippocampal volume, and cognitive performance of a world-famous nonagenarian track-and-field athlete.

    Physical activity (PA) and cardiorespiratory fitness (CRF) are associated with successful brain and cognitive aging. However, little is known about the effects of PA, CRF, and exercise on the brain in the oldest-old. Here we examined white matter (WM) integrity, measured as fractional anisotropy (FA) and WM hyperintensity (WMH) burden, and hippocampal (HIPP) volume of Olga Kotelko (1919-2014). Olga began training for competitions at age of 77 and as of June 2014 held over 30 world records in her age category in track-and-field. We found that Olga's WMH burden was larger and the HIPP was smaller than in the reference sample (58 healthy low-active women 60-78 years old), and her FA was consistently lower in the regions overlapping with WMH. Olga's FA in many normal-appearing WM regions, however, did not differ or was greater than in the reference sample. In particular, FA in her genu corpus callosum was higher than any FA value observed in the reference sample. We speculate that her relatively high FA may be related to both successful aging and the beneficial effects of exercise in old age. In addition, Olga had lower scores on memory, reasoning and speed tasks than the younger reference sample, but outperformed typical adults of age 90-95 on speed and memory. Together, our findings open the possibility of old-age benefits of increasing PA on WM microstructure and cognition despite age-related increase in WMH burden and HIPP shrinkage, and add to the still scarce neuroimaging data of the healthy oldest-old (>90 years) adults.

    The authors propose a micro-grid for autonomous wind-and-hydrogen power generation thus replacing such traditional fossil-fuelled equipment as domestic diesel generators, gas micro-turbines, etc. In the proposed microgrid the excess of electrical energy from a wind turbine is spent on electrolytic production of hydrogen which is then stored under low-pressure in absorbing composite material. The electrolyser has a non-traditional feeding unit and electrode coatings. The proposed DC/DC conversion topologies for different micro-grid nodes are shown to be well-designed. The prototypes elaborated for the converters and hydrogen storage media were tested and have demonstrated a good performance.

    This article is focused on investment planning in power generation industry, which becomes an important direction of research under the conditions of newly formed environment of electricity market. The authors emphasize the key role of effective instruments and methods for estimation of the costs and economic efficiency of a generating capacity and its adequacy in a modern power system. In the paper, cost-based concepts are analyzed which form a basis for decision-making and long-term planning of investments in the power generation sector for a power system with high share of renewable energy sources. Mūsdienās energoinfrastruktūras attīstības un tā vadības procesā ir jāpieņem un jāpilda vairāki lēmumi par nepieciešamiem kapitālieguldījumiem, kas ir rūpīgi jāplāno un jāpamato. Viedo tīklu tehnoloģiju ieviešana un energosistēmas drošuma uzturēšana, ņemot vērā liberalizēto elektroenerģijas tirgu, rada nepieciešamību pēc principiāli jaunām pieejām un metodēm kapitālieguldījumu novērtēšanas uzdevumu risināšanai. Pētījums veltīts investīciju plānošanai elektroenerģijas ģenerācijas iekārtai elektroenerģijas tirgus apstākļos, ņemot vērā lielo atjaunīgo energoresursu (AER) īpatsvaru. Modernu energosistēmu vadība prasa pietiekamu ģenerācijas jaudas elastīgumu un to pareizo kombināciju. Lai to sasniegtu, vispirms ir nepieciešama dažādu ģenerācijas tehnoloģijas izmaksu novērtēšana, ko var veikt, izmantojot pienācīgo instrumentu. Tas arī ir pētījuma mērķis, kura rezultātā tika piedāvāta elektrostaciju ekonomiskas dzīvotspējas novērtēšanas koncepcija, balstoties uz elektroenerģijas ražošanas līmeņizmaksām (ed costs), lai salīdzinātu dažādu elektroenerģijas ražošanas tehnoloģijas izmaksas. Lai to sasniegtu tika veikti: - investīciju plānošana ģenerācijā, metožu pētīšana; - elektrostaciju darbības principu analīze elektroenerģijas tirgū; - elektrostaciju

    Realistic representation of the land surface is crucial in global climate modeling (GCM). Recently, the Mosaic land-surface Model (LSM) has been driven off-line using GEOS DAS (Goddard Earth Observing System Data Assimilation System) atmospheric forcing, forming the Off-line Land-surface Global Assimilation (OLGA) system. This system provides a computationally efficient test bed for land surface data assimilation. Here, we validate the OLGA simulation of surface processes and the assimilation of ISCCP surface temperatures. Another component of this study as the incorporation of the Physical-space Statistical Analysis System (PSAS) into OLGA, in order to assimilate surface temperature observations from the International Satellite Cloud Climatology Project (ISCCP). To counteract the subsequent forcing of the analyzed skin temperature back to the initial state following the analysis. incremental bias correction (IBC) was included in the assimilation. The IBC scheme effectively removed the time mean bias, but did not remove him in the mean diurnal cycle. Therefore, a diurnal him correction (DBC) scheme was developed, where the time-dependent bias was modeled with a sine wave parameterization. In addition, quality control of the ISCCP data and anisotropic temperature correction were implemented in PSAS. Preliminary results showed a substantial impact from the inclusion of PSAS and DBC that was visible in the surface meteorology fields and energy budget. Also, the monthly mean diurnal cycle from the experiment closely matched the diurnal cycle from the observations.

    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

    The operational conditions of new networks dictate new requirements for the transmission planning, which would include the electricity market figures and a sizable involvement of renewable generation. This paper focuses on the transmission expansion planning techniques based on the calculations of optimal power flows and on the concept of development planning and sustainability. A description is given for the mathematical model of calculations and analysis of transmission system. The results have shown that the Baltic transmission system infrastructure can successfully be analyzed based on the proposed methodology and developed mathematical model Baltijas valstu (Latvijas, Lietuvas un Igaunijas) energosistēmas ir cieši saistītas vēsturiski, un to darbība nav iespējama bez savstarpējas sadarbības attīstības un darba režīmu jautājumos.

    Generation of chaos in response systems is discovered numerically through specially designed unidirectional coupling of two glow discharge-semiconductor systems. By utilizing the auxiliary system approach, [H. D. I. Abarbanel, N. F. Rulkov, and M. M. Sushchik, Phys. Rev. E 53, 4528–4535 (1996)] it is verified that the phenomenon is not a chaos synchronization. Simulations demonstrate various aspects of the chaos appearance in both drive and response systems. Chaotic control is through the external circuit equation and governs the electrical potential on the boundary. The expandability of the theory to collectives of glow discharge systems is discussed, and this increases the potential of applications of the results. Moreover, the research completes the previous discussion of the chaos appearance in a glow discharge-semiconductor system [D. D. Šijačić U. Ebert, and I. Rafatov, Phys. Rev. E 70, 056220 (2004).].

    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 cap 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.

    In the recent years, there has been significant research focus on the safety and reliability of data harvesting and optimal energy consuming by wireless sensor network nodes. If external electrical power fails, the node needs to be able to send notifications to the utility demanding the use of backup energy strategies. The authors of the research offer an approach that can help to use PV panels as an alternative power source for WSN nodes in particular irradiation conditions. Survey and testing of the main types of PV panels offered on the market in conditions closed to real ones, in which WSN nodes are maintained, have been implemented. Based on the test results, maximum power control module parameters can be calculated in order to achieve the best effectiveness of the power control system for a selected type of PV panel or panel group. The novelty of the research is an approach that includes an original test bed design for PV testing, PV testing method and selection of design and MPP control module parameters, which ensure maximum effectiveness of WSN node power feeding.

    1997-12-31

    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 demonstrated that Sg oxichlorides are indeed less volatile than their lighter homologue W- and Mo-oxichlorides.

    2011-02-01

    A ground based facility (OLGA), providing magnetic compensation of gravity in oxygen, has been developed. A 2-T superconducting magnetic solenoid is used to create the required magnetic field. A novel electrical supply permits to quickly vary the magnetic field, leading to rapid variation of the acceleration forces applied to oxygen. These variations can be made from overcompensation of gravity (-0.5 g) to zero gravity or from zero gravity to reduced gravity (0.4 g) with a time constant of 340 ms. This time is typical of the cutoff or reignition of spacecraft engines. Preliminary results on the transient flows induced by these acceleration variations in a reservoir filled with liquid and gaseous oxygen are presented.

    Since the solar wind phenomenon has been revealed and confirmed, one of the most intriguing problems was to understand processes in the solar atmosphere and their relation with the solar wind characteristics at different distances from the Sun. Analysis of multi-spacecraft measurements of plasma parameters and the interplanetary magnetic field provides us with knowledge about the heliosphere from global to small scales. Comparisons of observations with models, describing small-scale processes, usually give more positive results than in the case of models comparison with the solar wind properties at the scales larger than several proton gyroradii. For example, Parker-like models face with big problems in their attempts to predict the solar wind plasma and, especially, the behaviour of the interplanetary magnetic field. Observations show that the radial component of the interplanetary magnetic field depends on heliolatitude and radially decreases with a slope of -5/3 instead of the predicted slope of -2 (Khabarova, Obridko, ApJ, 2012; Khabarova, Astronomy Reports, 2013). This may be determined by small-scale processes occurring in some vicinity of the heliospheric current sheet and related to the magnetic reconnection (Zharkova, Khabarova, ApJ, 2012). In this report we present results of data analysis of eight spacecraft to study variations of plasma, the electric and magnetic field with distance and heliolatitude. begin{enumerate} Zharkova V., Khabarova O., Particle Acceleration in the Reconnecting Heliospheric Current Sheet: Solar Wind Data Versus 3D PIC Simulations, Astrophysical Journal, 2012, V.752, 1, 35 doi:10.1088/0004-637X/752/1/35 begin{enumerate} 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 begin{enumerate} Khabarova Olga V., The interplanetary magnetic field: radial and latitudinal dependences.

    Under the conditions of continuous increase in the energy consumption, sharply rising prices of basic energy products (gas, oil, coal), deterioration of environment, etc., it is of vital importance to develop methods and techniques for heat and power generation from renewables. The paper considers the possibility to use a sail-type wind turbine for autonomous power supply in Latvia, taking into account its climatic conditions. The authors discuss the problems of developing a turbine of the type that would operate efficiently at low winds, being primarily designed to supply power to small buildings and farms distant from centralized electricity networks. The authors consider aerodynamic characteristics of such a turbine and the dependence of the thrust moment of its pilot model on the airflow rate at different angles of attack. The pilot model with a changeable blade shape has been tested and shows a good performance.

    Photocatalytic activity of TiO2 and ZnO nanopowders is studied depending on the morphology, grain sizes and method of synthesizing. Photocatalysis of the prepared powders was evaluated by degradation of the methylene blue aqueous solution. Absorbance spectra (190-100 nm) were measured during exposure of the solution to UV light. The relationships between the photocatalytic activity and the particle size, crystal polymorph phases and grain morphology were analyzed. The photocatalytic activity of prepared TiO2 nanopowders has been found to depend of the anatase-to-rutile phase ratio. Comparison is given for the photocatalytic activity of ZnO nanopowders prepared by sol-gel and solar physical vapour deposition (SPVD) methods Darbā pētīta fotokatalīzes efektivitāte ar dažādām metodēm sintezētiem TiO2 and ZnO nanopulveriem, kuriem ir atšķirīga morfoloģija un grauda izmērs.

    Southern Mexico and Central America have many water bodies of different morphology and water chemistry with an interesting zooplankton fauna, originating from North or South America. A set of 63 samples, taken in 2005 and 2008, from water bodies of the Yucatan Peninsula karst, Belize and Guatemala, were studied for the content of calanoid copepods. Old and recent literature was used to determine animals to species level. Drawings were prepared with a microscope and a camera lucida. A total of 32 samples with totally six species contained calanoid copepods: one estuarine pseudodiaptomid and five freshwater diaptomids. Pseudodiaptomus marshi was found at different salinities. It is confirmed that the commonest diaptomids in the Yucatan Peninsula are Arctodiaptomus dorsalis and Mastigodiaptomus nesus. The former was also recorded from Lake Amatitlan. Mastigodiaptomus nesus is as widespread as A. dorsalis but it is absent from the Lake Peten area in Guatemala. Mastigodiaptomus reidae was found in two shallow habitats, these specimens differ from those from the type locality by having a set of peculiar large spine-like processes on the last thoracic and the urosome segments of the females. Leptodiaptomus siciloides was found only in Lake Ayarza with high salinity. Prionodiaptomus colombiensis occurred in the highlands of Guatemala in Lago de Güija and in the Peten area in Laguna Sacpuy. We contributed with our occurrence records to a better knowledge of the geographic distribution of some calanoid copepods. Morphological findings in some species are of value for taxonomic differentiation between species.

    Inflammation, which is a highly regulated host response against danger signals, may be harmful if it is excessive and deregulated. Ideally, anti-inflammatory therapy should autonomously commence as soon as possible after the onset of inflammation, should be controllable by a physician, and should not systemically block beneficial immune response in the long term. We describe a genetically encoded anti-inflammatory mammalian cell device based on a modular engineered genetic circuit comprising a sensor, an amplifier, a "thresholder" to restrict activation of a positive-feedback loop, a combination of advanced clinically used biopharmaceutical proteins, and orthogonal regulatory elements that linked modules into the functional device. This genetic circuit was autonomously activated by inflammatory signals, including endogenous cecal ligation and puncture (CLP)-induced inflammation in mice and serum from a systemic juvenile idiopathic arthritis (sIJA) patient, and could be reset externally by a chemical signal. The microencapsulated anti-inflammatory device significantly reduced the pathology in dextran sodium sulfate (DSS)-induced acute murine colitis, demonstrating a synthetic immunological approach for autonomous anti-inflammatory therapy.

    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].

    The Deep Fault Drilling Project (DFDP) aims to improve our understanding of the Alpine Fault Zone, a tectonically active 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. During drilling, gas was extracted from returning drilling mud and changes in the gas composition were tracked by mass spectrometry (N2, O2, Ar, CO2, CH4, He, and H2), gas chromatography (CH4, C2H6, C3H8, i/n-C4H10), and alpha-spectrometry for 222Rn. The rapid formation of mud wall cake seals the borehole from fluid inflow along the borehole; hence formation-derived gases enter mostly at the drill bit during drilling. Gas was sampled for offline analyses on noble gas and stable isotopes to complement the dataset. 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. OLGA thus may provide information on fluid origins, flow rates and paths, fluid-rock interactions along these paths, and the permeability structure of the faulted rock mass. The principle formation-derived gases found in drilling mud during drilling of DFDP-2 were CO2 (≤1.7 vol.-%), H2 (<2.5 vol.-%), and CH4 (≤0.18 vol.-%), with minor contributions of He. Zones of enhanced gas concentrations and high radon activity are interpreted to reflect intervals of active fluid flow through highly fractured and faulted rock. Air-corrected 3He/4He values of samples from 236m (0.68 Ra), 610m (1.03 Ra) and 707m (0.63 Ra) show mantle helium contributions 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). CH4/C2H6 (~20) and δ13C of methane (-31.7 ‰ PDB) underpin a thermogenic origin of hydrocarbons at depths below 600m, while mixing with biogenic gas is indicated at shallower depth (δ13C of methane= -46.7

    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.

    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.

    The Critical Assessment of Function Annotation meeting was held July 14-15, 2011 at the Austria Conference Center in Vienna, Austria. There were 73 registered delegates at the meeting. We thank the DOE for this award. It helped us organize and support a scientific meeting AFP 2011 as a special interest group (SIG) meeting associated with the ISMB 2011 conference. The conference was held in Vienna, Austria, in July 2011. The AFP SIG was held on July 15-16, 2011 (immediately preceding the conference). The meeting consisted of two components, the first being a series of talks (invited and contributed) and discussion sections dedicated to protein function research, with an emphasis on the theory and practice of computational methods utilized in functional annotation. The second component provided a large-scale assessment of computational methods through participation in the Critical Assessment of Functional Annotation (CAFA). The meeting was exciting and, based on feedback, quite successful. There were 73 registered participants. The schedule was only slightly different from the one proposed, due to two cancellations. Dr. Olga Troyanskaya has canceled and we invited Dr. David Jones instead. Similarly, instead of Dr. Richard Roberts, Dr. Simon Kasif gave a closing keynote. The remaining invited speakers were Janet Thornton (EBI) and Amos Bairoch (University of Geneva).

    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.

    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.

    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.

    Cores from living coral colonies were collected from Dry Tortugas National Park, Florida, U.S.A., to obtain skeletal records of past coral growth and allow geochemical reconstruction of environmental variables during the corals’ centuries-long lifespans. The samples were collected as part of the U.S. Geological Survey Coral Reef Ecosystems Studies project (http:/coastal.er.usgs.gov/crest) that provides science to assist resource managers tasked with the stewardship of coral reef resources. Three colonies each of the coral species Orbicella faveolata and Siderastrea siderea were collected in May 2012 using the methods described herein and as approved under National Park Service scientific collecting permit number DRTO-2012-SCI-0001 and are cataloged under accession number DRTO-353. These coral samples can be used to retroactively construct environmental parameters, including sea-surface temperature, by measuring the elemental composition of the coral skeleton. The cores described here, and others (see http://olga.er.usgs.gov/coreviewer/), can be requested, on loan, for scientific study. Photographic images for each coral in its ocean environment, the coral cores as curated and slabbed, and the X-rays of the slabs can be found in an associated U.S. Geological Survey Data Release.

  15. Anton P. Chekhov, MD (1860-1904): dual medical and literary careers.

    Carter, R

    1996-05-01

    This is a story of a physician who was one of the world's greatest short story writers. Anton Pavlovich Chekhov successfully performed dual careers of writing and practicing medicine during a short but productive life. Many biographers overlook Dr Chekhov's role, although his medical training and practice flowed over into his writing, influencing both his subject matter and his style. His stories and plays reveal the insights that Dr Chekhov discovered about the human psyche at work, thus delving into psychosomatic medicine nearly 50 years before its time. Despite orders to stop practicing medicine because of his own deteriorating health, Chekhov devoted himself further to the study of medicine, publishing a landmark study in social medicine that advocated reform of the Russian penal system. Meanwhile, his fictional works earned him the coveted Pushkin prize for the best literary work of the year in 1888. Shortly after celebrating his third wedding anniversary to actress Olga Knipper, Anton Chekhov died at age 44, victim of a nearly lifelong battle with tuberculosis.

  16. A testcross procedure for selecting exotic strains to improve pure-line cultivars in predominantly self-fertilizing species.

    1996-01-01

    Methods for identifying germplasm carrying alleles with the potential to improve a particular single-cross hybrid have been proposed and discussed in recent years. There is a need for similar methods to be used in breeding crops for which pure-line cultivars, rather than hybrids, are the goal. The objective of this research was to develop a method to identify germplasm lines with the potential to contribute favorable alleles not present in a specified pure line or set of pure lines. Given a set of adapted pure lines (A 1, A 2 ..., A m) to be improved and a set of germplasm lines (P 1 P 2 ..., P f), the procedure consists of producing all f x m possible hybrids and evaluating them along with the parents. The testcross statistic T ij is defined by T ij=γ(F ij-A j)+(1-γ) (F ij-P i), where A j, P i, and F ij represent the performance of thej (th) adapted line, the i (th) germplasm line, and their hybrid, respectively. The statistic [Formula: see text] is the mean value of T ij over all adapted parents A j. If γ=(1/2)(1+d'), where d' = the mean degree of dominance, then T ij measures the potential for alleles from P i to improve A j and [Formula: see text] measures the potential for alleles from P i to improve the set A 1, A 2 ..., A m. Use of data on soybean and peanut hybrids published by other researchers suggests that the value assumed for d' has little effect on the P i chosen. The ability of the T ij and [Formula: see text] statistics to identify germplasm strains carrying rare favorable alleles should be assessed in empirical studies.

    The authors analyze the advantages and disadvantages of brushless synchronous electric machines with radially and non-radially mounted rectangular permanent magnets. The results show that the proposed nonradial mounting of permanent magnets considered in the paper, in several cases (e.g. multi-pole brushless generators with tooth windings of the armature) allows achievement of the following advantages: better technology of manufacturing the electric machine owing to simple packing of the stator winding in the stator open slots, which also increases the copper slot fillfactor; reduction in the mass-and-size of permanent magnets at least twice; significantly lower cost of the electric machine; and, finally, its greater specific power.

    The authors estimate the potential for power generation from water resources of small and medium-sized rivers, which are abundant in Latvia. They propose the algorithm for optimal operation of a small-scale hydropower plant (SHPP) at the chosen optimality criterion in view of the plant's participation in the market. The choice of SHPP optimization algorithm is made based on two mathematical programming methods - dynamic and generalized reduced gradient ones. Approbation of the algorithm is illustrated by an example of optimized SHPP operation.

    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 μM) 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, Km, Vmax, and Kcat, determined using 2,2′-azinobis-(-3-ethylbenzothiazoline-6-sulfonic acid) as substrate were found to be 110 μM, 36 μmol/min/mg, and 246 min−1, respectively. The isolated thermostable laccase will be used in future experiments for delignification process. PMID:27822471

    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)

  3. 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.

    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.

    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. 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]. 1.

  7. Ancient founder mutation is responsible for Imerslund-Gräsbeck Syndrome among diverse ethnicities

    PubMed Central

    2011-01-01

    Background Imerslund-Gräsbeck syndrome (IGS) was described just over 50 years ago by Olga Imerslund and Ralph Gräsbeck and colleagues. IGS is caused by specific malabsorption of cobalamin (Cbl) due to bi-allelic mutations in either the cubilin gene (CUBN) or the human amnionless homolog (AMN). Mutations in the two genes are commonly seen in founder populations or in societies with a high degree of consanguineous marriages. One particular mutation in AMN, c.208-2A>G, causing an out-of-frame loss of exon 4 in the mRNA, is responsible for some 15% of IGS cases globally. We present evidence that this founder mutation causes a substantial percentage of cases among diverse ethnicities and that the mutation is as old as human civilization. Methods Partial genotyping indicated a founder event but its presence in diverse peoples of Arabic, Turkish, Jewish, and Hispanic ancestry suggested that the mutation might be recurrent. We therefore studied the flanking sequence spanning 3.5 Mb to elucidate the origin of the haplotype and estimate the age of the mutation using a Bayesian inference method based on observed linkage disequilibrium. Results The mutation's distribution, the size of the shared haplotype, and estimates of growth rate and carrier frequency indicated that the mutation was a single prehistoric event. Dating back to the ancient Middle East around 11,600 BC, the mutation predates the advent of writing, farming, and the monotheistic religions of the region. Conclusions This mutation causes over 50% of the IGS cases among Arabic, Turkish, and Sephardic Jewish families, making it a primary target for genetic screening among diverse IGS cases originating from the Middle East. Thus, rare founder mutations may cause a substantial number of cases, even among diverse ethnicities not usually thought to be related. PMID:22078000

    The economic aspect considered in the work is related to the charging of an electric vehicle (EV) at a single private house when this is done every day. To perform the relevant cost estimation it was necessary to determine: the average annual electricity consumption under the condition of everyday charging an EV and the average electricity consumption off the mains for covering a distance of 100 km by an EV and the time in hours for its charging. Comparison is made for the day-time intervals from which it is possible to choose the preferable for proper loading the electric line and the most beneficial for the consumer. Under analysis are two EV connection scenarios for 100 individual households from which 10%, 20% and 30% have EVs, with 8-h duration of each charging at the current of 13A. The authors consider the consumption and electric energy payment packages which - with planned opening of the electric energy market on January 1, 2015 - will offer the clients the enterprises rendering services on the electric energy sale.

    Philae is the island in the river Nile on which an obelisk was found that had a bilingual inscription including the names of Cleopatra and Ptolemy in Egyptian hieroglyphs. This provided the French historian Jean-François Champollion with the final clues that enabled him to decipher the hieroglyphs of the Rosetta Stone and unlock the secrets of the civilisation of ancient Egypt. Just as the Philae Obelisk and the Rosetta Stone provided the keys to an ancient civilisation, the Philae lander and the Rosetta orbiter aim to unlock the mysteries of the oldest building blocks of our Solar System - comets. Germany, France, Italy and Hungary are the main contributors to the lander, working together with Austria, Finland, Ireland and the UK. The main contributors held national competitions to select the most appropriate name. Philae was proposed by 15-year-old Serena Olga Vismara from Arluno near Milan, Italy. Her hobbies are reading and surfing the internet, where she got the idea of naming the lander Philae. Her prize will be a visit to Kourou to attend the Rosetta launch. Study of Comet Churyumov-Gerasimenko will allow scientists to look back 4600 million years to an epoch when no planets existed and only a vast swarm of asteroids and comets surrounded the Sun. On arrival at the comet in 2014, Philae will be commanded to self-eject from the orbiter and unfold its three legs, ready for a gentle touchdown. Immediately after touchdown, a harpoon will be fired to anchor Philae to the ground and prevent it escaping from the comet's extremely weak gravity. The legs can rotate, lift or tilt to return Philae to an upright position. Philae will determine the physical properties of the comet's surface and subsurface and their chemical, mineralogical and isotopic composition. This will complement the orbiter's studies of the overall characterisation of the comet's dynamic properties and surface morphology. Philae may provide the final clues enabling the Rosetta mission to unlock

    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

    Nursery nitrogen application has been used to improve seedling quality. The technique has received little attention with bare-root seedlings and their subsequent field performance on weed competition sites. Our research objective was to examine responses of one- and two- year-old bare-root Olga Bay larch (Larix olgensis Henry) seedlings to nursery nitrogen supplements and subsequent one-year field performance on a competitive site. The fertilizer levels (kg N ha(-1)) were 0 (control), 60 (conventional fertilization, 60 C), 120 (additional nitrogen applied two times, 120 L), 180 (additional nitrogen applied three times, 180 L) and N were applied in increments of 30 kg ha(-1 )at 15-day interval to maintain a base nutrient level Although pre-planting morphological attributes and nitrogen status of one-year-old (la) seedlings were more sensitive to 60 C than for two-year-old (2a) seedlings, the conventional application failed to enhance their field survival (15.6% vs 17.8%), relative height growth (89.0% vs 79.6%), and relative diameter growth (17.0% vs 22.9%). The la seedlings' field survival (15.6% for 0, 17.8% for 60 C) and 2a seedlings' relative height growth rate (11.0% for 0, 8.9% for 60 C) were not increased significantly until they were provided the 120 L (survival of 23.3% for la, relative height growth rate of 15.0% for 2a). According to pre-planting attributes and field performance, optimum nursery nitrogen application was 120 L for the 2a seedlings and 180 L for la seedlings. Except for component nitrogen concentration, pre-planting morphological attributes and component N content for the 2a seedlings were as much 3.3 to 37.7 times that of la seedlings. In conclusion, the contrasting survival of poor (15.6%-28.9%) for la seedlings and high (84.4%-91.1%) for 2a seedlings indicated that additional nitrogen fertilizer would not equal the benefits of an another year's growth in the nursery. Successful reforestation could not be fulfilled by la seedlings

    Gas phase chromatography using The Heavy Element Volatility Instrument (HEVI) and the On Line Gas Apparatus (OLGA III) was used to determine volatilities of ZrBr4, HfBr4, RfBr4, NbBr5, TaOBr3, HaCl5, WBr6, FrBr, and BiBr3. 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. Adsorption Enthalpy (ΔHa) 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 ΔHa was observed: RfBr4 > ZrBr4 > HfBr4. The ΔHa 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

    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

    Cores from living coral colonies were collected from Dry Tortugas National Park, Florida, to obtain skeletal records of past coral growth and allow geochemical reconstruction of environmental variables during the corals’ centuries-long lifespans. The samples were collected as part of the U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies project (http://coastal.er.usgs.gov/crest/) that provides science to assist resource managers tasked with the stewardship of coral reef resources. Three colonies each of the coral species Orbicella faveolata and Siderastrea siderea were collected in May 2012 as approved under National Park Service (NPS) scientific collecting permit number DRTO-2012-SCI-0001. These coral samples can be used to retroactively construct sea-surface temperature records by measuring the elemental ratio of strontium (Sr) to calcium (Ca), and are valuable for measuring additional paleoproxies as new methods are developed. Flannery et al. (In press) includes temperature reconstructions using samples from one of the six (coral CG2) collected in this study. The core slabs described here, as well as others (see http://olga.er.usgs.gov/coreviewer/), can be requested on loan for further scientific study. Here we provide photographic images for each core depicting 1) the coral in its ocean environment, 2) the core as curated and slabbed, and 3) the X-rays of the slabs. More information on coring methods can be found in the associated U.S. Geological Survey Open-File Report 2016-1182 (Weinzierl et al., 2016). These coral samples are presently on loan from the NPS, stored at the USGS St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, and cataloged under accession number DRTO-353.Flannery, J.

    The JENAM symposium "Physics of Stars" took place on the 5th and 6th July of 2011 in Saint-Petersburg. This symposium had a wide-ranging look at observational and theoretical studies of stars and stellar systems. Several talks were devoted to accurate determination of fundamental stellar parameters, such as star's mass, radius, effective temperature, surface gravity, chemical composition. This is particularly crucial to fully exploit the data from the new generation of large ground-based telescopes and future space missions like the GAIA one. Viktor Orlov reported the measurements of stellar mass for a few multiple systems and also the investigation of their dynamical stability. To improve the determination of parameters of the components in an eclipsing binary system including a Wolf-Rayet star, Eleonora Antokhina and her co-workers updated their synthesis model by accounting for the absorption in the expanding stellar wind. The variable stars are excellent laboratories to study the physical processes either occurring at certain stages of stellar evolution or caused by the interaction of a star with its companion or circumstellar medium. Nikolay Samus reported the discovery of hundreds of new variable stars in their work on digitalization of the Moscow stacks of sky photographs. The exotic star VSX J052807.9+725606, with a very strong asymmetry of maxima, wavelength dependence of amplitude, and the shift of the secondary minimum from the phase 0.5, was discovered by Natalia Virnina. Michael E. Contadakis and his co-workers presented the additional observational evidences for weak transient optical oscillations of the red dwarf AD Leo. Spectral variability of the two massive luminous stars in the M33 galaxy was studied by Olga Maryeva. Alex Dudorov and Sergei Zamozdra and Alexander Grigoriev et al. discussed the theoretical and observational problems of star formation.

    Passenger cars of the railway transport are being constantly improved, thus becoming ever more comfortable for public conveyance. These cars are fitted with air conditioners, installations for heating and forced ventilation, heaters, refrigerators; lighting, radio and TV sets; communication equipment, etc. All the listed fittings need continuous and secure electricity supply from a primary independent source. The paper considers the possibilities of meeting requirements for particular power supply systems - first of all for undercar generators. At operation of such a high-power generator under rugged conditions it should be highly reliable, possessing a reasonable mass and high efficiency. The existing designs of these generators still do not meet the listed requirements in full measure. To improve the efficiency of the undercar generator it is proposed to integrate its excitation winding into the armature one, thus reducing the copper consumption, losses and mass, while - which is the most important - considerably raising reliability of the generator and its availability factor.

    The use of complementary and alternative medicine (CAM) is widespread around the world including Croatia. The number of studies that investigate both quantitative and qualitative use of CAM in Croatia is limited. The aim of this study was to investigate the use of CAM among family medicine patients in the town of Čakovec and the rate they report it to their family doctor. This was a cross-sectional study in a sample of 300 patients that visited primary health center for any reason. We used anonymous questionnaire already employed in a previous investigation (Čižmešija et al. 2008), which describes socioeconomic characteristics, modalities of CAM use, and reasons for use. We also added questions on the type of herbs used and use of over-the-counter vitamin and mineral supplements. On data analysis we used descriptive statistics, χ2-test and Fisher's exact test, while the level of statistical significance was set at p ≤ 0.05. The response rate was 76%. Out of the total number of patients, 82% used some modality of CAM. Women, patients with secondary school education, employed and retired persons used CAM more often. Students and pupils reported least use of CAM. The most commonly used were herbs (87%), bioenergy (29%), diet therapy (28%), chiropractics (22%), and homeopathy and acupuncture (11% each). Vitamin and mineral supplements were used by 77% of study subjects. CAM was most frequently used for respiratory, urinary and musculoskeletal problems, as well as to improve overall health condition. Of the respondents that reported CAM use, 55% believed it would help them, 43% used it because they wanted to try something new, while only 2% indicated dissatisfaction with their physician as the reason for using CAM. Statistically, there were more subjects that used CAM and did not notify their family doctor about it, which could indicate poor communication between family doctors and health care users. Our results are consistent with a previous quantitative study

    In the work, the life-cycle assessment approach is applied to the planning of waste management development in a seaside region (Piejūra) using the Waste Management Planning System (WAMPS) program. In Latvia, the measures to be taken for the climate change mitigation are of utmost importance - especially as related to the WM performance, since a disposal of biodegradable waste presents the primary source of GHG emissions. To reduce the amount of such waste is therefore one of the most significant goals in the State WM plan for 2013-2020, whose adoption is the greatest challenge for municipalities. The authors analyse seven models which involve widely employed biomass processing methods, are based on experimental data and intended for minimising the direct disposal of organic mass at the solid waste landfills. The numerical results obtained evidence that the thermal or biotechnological treatment of organic waste substantially reduces the negative environmental impact of WM practices - by up to 6% as compared with the currently existing.

    The simple analysis method has been introduced for the kinetic analysis of the hydrothermal growth. The zinc oxide nanorod arrays have been synthesized via a hydrothermal process. Zinc nitrate hexahydrate (Zn(NO3)2 · 6H2O) has been used as the precursor in the presence of hexamethylenetetramine (C6H12N4) for the formation of ZnO nanostructures. Long-term isothermal growth kinetics of ZnO nanorods has been investigated. The effect of the solution temperature (70-90 ℃) on the kinetics of the hydrothermal growth of ZnO nanorods has been examined. An extensive analysis by scanning electron microscopy, energy dispersive spectroscopy and x-ray diffraction has revealed that the as-synthesized ZnO nanorod arrays are well-crystalline and possessing hexagonal wurtzite structure. These ZnO films have promising potential advantages in microelectronic and optoelectronic applications. Tiek piedāvāta vienkārša analīzes metode kristālu hidrotennālās augšanas kinētikasizpētei.

  11. Geomorphic Processes Along the Coastal Cliff, Central Coastline - Israel

    2007-12-01

    A study aimed at finding the nature, rate and causes of the morphological changes in the coastal cliff in central part of Israeli coastline, was carried out between 1991 and 1996, along the coast of Michmoret - Giv'at Olga, Israel. The stratigraphical sequence of this cliff, which is of Pleistocene age, consists of alternating layers of Kurkar (a carbonate cemented quartz eolianite) and Hamra (a red brown sandy loam). The morphological changes occurring in the coastal cliff were documented, prior, during and immediately after storms, by field observation, redundant surveying and photography. The retreat of the coastal cliff is composed of several steps. As a rule the moisture level in the Hamra layers is higher than that of the Kurkar layers because of the higher content of silt and clay in the Hamra. During the rainy season the increase of moisture in the Hamra increases the relative weight and lowers its friction. This in turn intensifies the process of rill development in the Hamra layers and slides of material from this layer occur. As a result the overlying Kurkar remains without support, until the overhanging Kurkar breaks down and falls to the bottom of the cliff. The debris, which accumulates at the foot of the cliff, forms a moderate slope and a stable cliff profile, which prevents continuation of the erosion process. This does not last for long, because sea waves remove the debris from the foot of the cliff leaving it with a precipitous slope and vulnerable to further erosion. The magnitude of the landslide or rock fall event determines, to a certain degree, the frequency of the event. The larger the event, the less likely another landslide or rock fall will occur at the same point in the near future. Losses of soil and rill development at the cliff slopes are a result of runoff action. The wind action has an effect on the erosion of the coastal cliff by blowing the loose sand from Kurkar and Hamra layers. The main factors influencing the changes (retreat

    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 chains 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 lower limit on the partial SF half-life of {sup 266}Sg is in good agreement with

It is a true oasis and the perfect hide-out for Dominic Greene, our villain, whom 007 is tracking in our new James Bond film." In addition to the shooting at the Residencia, further action will take place at the Paranal airstrip. The film crew present on Paranal includes Englishman Daniel Craig, taking again the role of James Bond, French actor Mathieu Amalric, leading lady Olga Kurylenko, from the Ukraine, as well as acclaimed Mexican actors, Joaquin Cosio and Jesus Ochoa. This cast from across Europe and Latin America mirrors the international staff that works for ESO at Paranal. After leaving Paranal at the end of the week, the film crew will shoot in other locations close to Antofagasta. Other sequences have been filmed in Panama and, following the Chilean locations, the unit will be travelling to Italy and Austria before returning to Pinewood Studios near London in May. QUANTUM OF SOLACE will be released in the UK on 31 October 2008, and in the US and internationally on 7 November 2008.

    George Martin Baer, known for his development of the oral rabies vaccine instrumental in rabies control in Europe, died on 2 June 2009 at the age of 73 in Mexico City, Mexico. He was born on 12 January 1936 in London, England, to German immigrants who had fled Nazi Germany. His family emigrated to the United States in 1940 where he grew up in New Rochelle, New York. George had a love of animals, particularly horses, which may have influenced his career path. He earned an undergraduate degree in agricultural sciences in 1954 from Cornell University followed by a degree in veterinary medicine in 1959. He then went on to earn a master's degree in public health in 1960 from the University of Michigan. During some time in Mexico, George met and fell in love with his wife, Maria Olga Lara. Thanks to James H. Steele, his long-time friend and mentor, he started his public health career with the Centers for Disease Control (CDC) and was assigned to the New York State Health Department where he learned epidemiology and virology. He went on to work on bat rabies at the CDC's Southwest Rabies Investigations Laboratory in New Mexico. From 1966 to 1969, he worked with the National Institute for Livestock Research (Instituto Nacional de Investigaciones Pecuarias: INIP) in Mexico and helped develop the Plan Derriengue to control paralytic bovine rabies which became the early work in the development of Mexico's rabies control programmes. He returned to Atlanta in 1969 to direct the CDC Rabies Laboratory. There, he led a team of researchers in developing an oral rabies vaccine for wildlife, earning him the title 'The Father of Oral Rabies Vaccination'. His text, The Natural History of Rabies, first published in 1975 and again in 1991, continues to be a definitive international reference for rabies control. After his retirement, George returned to Mexico and continued his research and training, working to develop not only public health programmes, but new researchers as well. At the

    intrinsic water use efficiency. 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.

Our institute takes part since 2004 in adapting environmentally the schools in the Balearics which consists of developing activities which aim is that both teachers and students acquire habits so as to apply to their ordinary lives though different participative commissions ( 10-15 teachers): 1st commission: recycling and reusing materials. Enough bins in the classrooms and floors: yellow for plastic, blue for paper, and green for the other. We tend to use recycled materials in different celebrations such as Carnival, Christmas, Saint Jordi and Environmental day. We also organise workshops for the teachers to develop afterwards with the students and nature of environmental exposures. 2nd commission: Scatter information ( MonMaura, Maurifull, Green window and website).Throughout different means we inform the teachers and students about all the school activities and where to consult.( www.iesantonimaura.net, Playful area , environmental project ). 3rd commission: Reusing text books.( there is a students service of borrowing books and giving them back at the end of the school year if the book is in good use.) 4th commission: Improving the school surroundings, the back garden and garden with native plants. Department of Biology and Geology is responsible for caring for an organic garden and in turn improve the center's garden with native plants within the

    Electroweak and Flavor Physics in whose classification we had Quark masses and mixing, Electroweak Symmetry Breaking, Heavy Quark Physics, Neutrinos, CP Violation, CKM and Rare Decays. 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

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.
