Fast-rotating nearby solar-type stars - I. Spectral classification, v sin i, Li abundances and X-ray luminosities

We present the results of high-resolution spectroscopic and high-precision photometric observations on a sample of 129 late-F and G-type nearby stars selected on the basis of their large rotational velocity. Using also data from the Hipparcos satellite, CORAVEL and from the ROSAT satellite database, we infer spectral types, compute radial velocities, v sin i, Li abundances and X-ray luminosities and investigate the single or binary nature of the sample stars. Such a careful analysis of our sample shows a large fraction of binaries ('62%) and of young single disk stars. In particular, at least 9 stars can be considered bona-de PMS or ZAMS objects, and 30 stars are identied as SBs for the rst time. Information on the presence of Ca II K emission and on optical variability is given for some of the stars of the sample.
Effect of peppermint (Mentha piperita) supplementation on carcass yield, meat taste, heart weight, liver weight and some blood parameters in laying quail (Coturnix Coturnix Japonica) (2)

This study was carried out to determine the effects of peppermint (Mentha Piperita) on blood parameters (cholesterol, triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), malondialdehyte (MDA), antioxidant activity (AOA), total protein, glucose, carcass yield, heart, liver weights and organoleptic control of the carcasses in laying quails. A total of 180 15 week old laying quails were used in the study. There were 5 experimental groups which were supplemented with different ratios of Peppermint up to 5%. The control group received no peppermint supplements. The experiment continued for 10 weeks. Antioxidant activity and HDL amounts increased (P 0.05) on the carcass quality with a 5 % peppermint supplementation to the diet. In conclusion, the supplementation of peppermint to diets up to a 5% level was found to be quite beneficial in terms of blood parameters such as MDA, AOA, LDL, and HDL.
Measurement theory.

The usefulness and truthfulness of assessments, whether performed in the clinic on one patient or in the research laboratory on many subjects, depends on valid measurements. Measurement theory is the thought process and interrelated body of knowledge that form the basis of valid measurements. Translation of measurement theory to behaviors helps to ensure the integrity and relevancy of tests and the data that result from them. In the final analysis, useful and truthful data depend for their existence on scalable and detectable events being translated into pertinent, valid, and reliable measurements. The rules by which numbers are assigned to events form the basis of measurements theory.

Uncreative Writing: Managing Language in the Digital Age

Can techniques traditionally thought to be outside the scope of literature, including word processing, databasing, identity ciphering, and intensive programming, inspire the reinvention of writing? The Internet and the digital environment present writers with new challenges and opportunities to reconceive creativity, authorship, and their relationship to language. Confronted with an unprecedented amount of texts and language, writers have the opportunity to move beyond the creation of new texts and manage, parse, appropriate, and reconstruct those that already exist. In addition to explaining his concept of uncreative writing, which is also the name of his popular course at the University of Pennsylvania, Goldsmith reads the work of writers who have taken up this challenge. Examining a wide range of texts and techniques, including the use of Google searches to create poetry, the appropriation of courtroom testimony, and the possibility of robo-poetics, Goldsmith joins this recent work to practices that date back to the early twentieth century. Writers and artists such as Walter Benjamin, Gertrude Stein, James Joyce, and Andy Warhol embodied an ethos in which the construction or conception of a text was just as important as the resultant text itself. By extending this tradition into the digital realm, uncreative writing offers new ways of thinking about identity and the making of meaning.

Pneumococcal polysaccharide vaccine.

S. pneumoniae reste l’agent pr incipal des pneumopathies bacteriennes, dans (quasi) toute la litterature, et de loin celui dont la morbidite et la mortalite sont les plus importantes, tout specialement en cas de septicemie concomitante (± 20 %). A ceci s’ajoute une resistance croissante aux antibiotiques, qui exclut l’emploi empirique de certaines molecules (macrolides ou tetracyclines par exemple), necessite une augmentation des posologies d’autres (betalactames) ou conduit a l’emploi de nouvelles molecules, plus couteuses (nouvelles fluoroquinolones).
Quasi-maximum likelihood estimation for cointegrated solutions of continuous-time state space models observed at discrete time points

In this paper we investigate quasi-maximum likelihood (QML) estimation for the parameters of a cointegrated solution of a continuous-time linear state space model observed at discrete time points. The class of cointegrated solutions of continuous-time linear state space models is equivalent to the class of cointegrated continuous-time ARMA (MCARMA) processes. The model is not in innovation form. Therefore we have to construct some pseudo-innovations to be able to define a QML-function. We divide the parameter vector appropriate in long-run and short-run parameters using a representation for cointegrated solutions of continuous-time linear state space models as a sum of a Levy process plus a stationary solution of a linear state space model. Then we establish the consistency of our estimator in three steps. First, we show the consistency for the QML estimator of the long-run parameters. In the next step, we calculate its consistency rate. Finally, we use these results to prove the consistency for the QML estimator of the short-run parameters. After all we derive the limiting distributions of the estimators. The long-run parameters are asymptotically mixed normally distributed whereas the short-run parameters are asymptotically normally distributed.
EFFECT OF A NEW WAL-MART SUPERCENTER ON LOCAL RETAIL FOOD PRICES

In this study, we monitored food price changes in Athens-Clarke County, Georgia. Georgia has 42 metropolitan counties and 117 nonmetropolitan counties (Selig Center for Economic Growth, 1998). As a small metropolitan area, Athens has several traditional supermarkets. The Wal- Mart supercenter in Athens opened on January 25, 2000. The addition of the Wal-Mart supercenter was expected to increase price competition among existing supermarkets and food retailers in Athens. The effect of increasing competition from the Wal-Mart supercenter could force traditional supermarkets to change and adopt new food-pricing strategies. The objective of this study is to determine the impact of the opening of a new Wal-Mart supercenter on retail food prices among selected supermarkets in Athens, Georgia.
Evaluation of the development and yielding potential of Chenopodium quinoa Willd under the climatic conditions of Europe - Part One Accomodation of Chenopodium quinoa Willd to different conditions

Based on the evaluation of selected varieties of Chenopodium quinoa , their requirements were identified; it was shown which varieties demonstrated the best effects in what conditions. It was found that the best varieties for Europe's conditions were E-DK-4-PQCIP and RU-5-PQCIP. E-DK-4-PQCIP variety showed the best effects under the conditions of cluster II which included e.g. Bydgoszcz (Poland) and cluster IV which included Southern European countries (Greece and Italy), while the best effects found in RU-5-PQCIP variety were identified in cluster I which included Sweden. E-DK-4-PQCIP variety in cluster II showed a very high yield of green matter and a mean seed yield, and in cluster IV - a very high seed yield and a high yield of green matter.
SPIN-UP OF HOMOGENEOUS AND STRATIFIED FLUIDS

We consider the manner in which a container filled with viscous fluid adjusts to changes in its rotation rate. We begin with homogeneous flows involving small departures in rotation rate from an initial state of solid-body rotation in an axisymmetric container. This is followed by a summary of other more recent developments, including weakly and fully nonlinear calculations and comparison with experiment and the question of spin-down. The question of "spin-over" is addressed, followed by a brief synopsis of free-surface effects, and a discussion of nonaxisymmetric spin-up. The second part of the review focuses on the effects of stratification on the spin-up process. Linearized (low Rossby number) spin-up within a cylindrical container is described. Thereafter, both experimental and nonlinear computational results are described and compared. The final section focuses on stratified spin-up and spin-down in conical geometries, and a number of comparisons between theory and experiment are given.
Modeling gas-phase H2O between 5 μm and 540 μm toward massive protostars

We present models and observations of gas-phase H2O lines between 5 and 540m toward deeply embedded massive protostars, involving both pure rotational and ro-vibrational transitions. The data have been obtained for 6 sources with both the Short and Long Wavelength Spectrometers (SWS and LWS) on board the Infrared Space Observatory (ISO) and with the Submillimeter Wave Astronomy Satellite (SWAS). For comparison, CO J = 7 6 spectra have been observed with the MPIfR/SRON 800 GHz heterodyne spectrometer at the James Clerk Maxwell Telescope (JCMT). A radiative transfer model in combination with dierent physical/chemical scenarios has been used to model these H2O lines for 4 sources to probe the chemical structure of these massive protostars. The results indicate that pure gas-phase production of H 2O cannot explain the observed spectra. Ice evaporation in the warm inner envelope and freeze-out in the cold outer part are important for most of our sources and occur at T 90-110 K. The ISO-SWS data are particularly sensitive to ice evaporation in the inner part whereas the ISO-LWS data are good diagnostics of freeze-out in the outer region. The modeling suggests that the 557 GHz SWAS line includes contributions from both the cold and the warm H2O gas. The SWAS line profiles indicate that for some of the sources a fraction of up to 50% of the total flux may originate in the outflow. Shocks do not seem to contribute significantly to the observed emission in other H2O lines, however, in contrast with the case for Orion. The results show that three of the observed and modeled H2O lines, the 303 212; 212 101 ,a nd 1 10 101 lines, are good candidates to observe with the Herschel Space Observatory in order to further investigate the physical and chemical conditions in massive star-forming regions.
The Brauer Group of the Universal Moduli Space of Vector Bundles Over Smooth Curves

We compute the Brauer group of the universal moduli stack of vector bundles on (possibly marked) smooth curves of genus at least three over the complex numbers. As consequence, we obtain an explicit description of the Brauer group of the smooth locus of the associated moduli space of semistable vector bundles, when the genus is at least four.
Carbon and oxygen abundances in stellar populations

Abundances of C, O, and Fe are determined for F and G main-sequence stars in the solar neighborhood in order to study trends and systematic differences in the C/Fe, O/Fe, and C/O ratios for stellar populations. Carbon abundances are determined from the CI lines at 5052 and 5380 AA and oxygen abundances from the OI triplet at 7774 AA and the [OI] line at 6300 AA. MARCS model atmospheres are applied and non-LTE corrections for the OI triplet are included. Systematic differences between high- and low-alpha halo stars and between thin- and thick-disk stars are seen in the trends of [C/Fe] and [O/Fe]. The two halo populations and thick-disk stars show the same trend of [C/O] versus [O/H], whereas thin-disk stars are shifted to higher [C/O]. Furthermore, we find some evidence of higher C/O and C/Fe ratios in stars hosting planets than in stars for which no planets have been detected. The results suggest that C and O in both high- and low-alpha halo stars and in thick-disk stars are made mainly in massive stars, whereas thin-disk stars have an additional carbon contribution from low-mass AGB and massive stars of high metallicity causing a rising trend of C/O with increasing metallicity. However, the C/O ratio does not exceed 0.8, which seems to exclude formation of carbon planets if proto-planetary disks have the same composition as their parent stars.
Working Paper Series THE PEOPLE ’ S REPUBLIC OF CHINA IN THE MIDDLE-INCOME TRAP ?

Over the last decade, a growing body of literature dealing with the phenomenon of the “middle-income trap” (MIT) has emerged. The term MIT usually refers to countries that have experienced rapid growth and thus reached the status of a middle-income country (MIC) in a very short period of time, but have not been able to further catch up with the group of high-income economies. In particular, since the beginning of the growth slowdown of the economy of the People’s Republic of China (PRC) in 2011, there has been rising concern that the PRC is, or will also be, confronted with such a trap. This paper analyzes the PRC’s MIT situation taking into account both the (absolute and relative) empirical MIT definitions and MIT triggering factors identified in the literature. We not only survey the recent literature, but also make our own MIT forecasts and analyze under which conditions the PRC could be caught in an MIT.
A web-based national test of English reading as a foreign language: Does it test language ability, or computer competence? – A web-based measure of English reading and ICT competence

subjects were 389 nine to sixteen-year-old pupils who participated in the Norwegian web- based National Assessment in English Reading as a foreign language. The pupils' achievement in English, their self-reported Information and Communication Technologies (ICT) competence, and general ability were assessed. Using regression analyses, self-reported ICT competence, but not gen- eral ability scores, had a significant relation to English reading scores in the 4 th grade but not in the 10 th grade. In contrast, general ability, but not self-reported ICT competence, was significantly related to English reading for the 10 th graders. The results at both grade levels were replicated in separate gender-wise analyses. The findings indicate that the computerized National Test in English reading in lower school grades is a test of computer competence or computer familiarity, more so than achievement in English. Thus, there are serious issues of validity involved when using compu- terized tests in primary schools.
A PSYCHOMETRIC ANALYSIS OF THE UTRECHT WORK ENGAGEMENT SCALE IN THE SOUTH AFRICAN POLICE SERVICE

The objectives of this research were to validate the Utrecht Work Engagement Scale (UWES) for the South African Police Service (SAPS) and to determine its construct equivalence and bias in different race groups. A cross-sectional survey design was used. Stratified random samples (N = 2396) were taken of police members of nine provinces in South Africa. The UWES and a biographical questionnaire were administered. Structural equation modelling confirmed a 3-factor model of work engagement, consisting of Vigour, Dedication and Absorption. These three factors have acceptable internal consistencies. Exploratory factor analysis with target rotations showed equivalence of the three factors for different race groups in the SAPS. No evidence was found for uniform or non-uniform bias of the items of the UWES for different race groups. OPSOMMING Die doelstellings van hierdie navorsing was om die Utrecht-werksbegeesteringskaal (UWES) te valideer vir die SuidAfrikaanse Polisiediens (SAPD) en die konstrukekwivalensie daarvan vir verskillende rassegroepe te bepaal. ’n Dwarssnee opname-ontwerp is gebruik. Gestratifiseerde ewekansige steekproewe (N = 2396) is van polisielede uit nege provinsies geneem. Die UWES en ’n biografiese vraelys is afgeneem. Strukturele vergelykingsmodellering het ’n 3-faktormodel, bestaande uit Energie, Toewyding en Absorpsie, aangetoon. Hierdie drie faktore het aanvaarbare interne konsekwentheid getoon. Eksploratiewe faktoranalise met teikenrotasies het konstrukekwivalensie vir die drie faktore vir verskillende rassegroepe in die SAPD getoon. Bewyse is nie gevind vir uniforme of nie-uniforme sydigheid van die items van die UWES vir verskillende rassegroepe nie.
Ciliate-generated advective seawater transport supplies chemoautotrophic ectosymbionts

Variations of (O2) and (H2S) in seawater surrounding laboratory-reared sessile ciliates with ectosymbiotic chemoautotrophic bacteria were studied at high spatial and temporal resolutions using amperometric microsensors. We show how suspension feeding by the colonial Zoothamnium niveum and the solitary Vorticella sp. in the chemocline (O2/H2S-interface) of near-natural and arti- ficial H2S-releasing substrates generates the physico-chemical microenvironment for the ectobiotic bacteria. Continuous recordings revealed a steep increase of (O2) and decrease of (H2S) in the proxi- mal region of Z. niveum colonies during rapid stalk contraction. Hydrogen sulphide concentrations 2.5 mm above the substrate (upper end of the fully extended colony) increased when the contracted colony extended, followed by a decrease after the colony attained the fully upright position. Multiple contractions without complete extension successively transported sulphidic seawater upwards. The solitary Vorticella sp. maintained high ambient (O2) and low (H2S) 350 µm above the H2S-releasing membrane by generating a vertical flow field that drew seawater from above toward the ciliate. Oxygen concentration at the proximal part of Vorticella sp. did not increase during contraction, whereas during slow extension deoxygenated seawater was transported upwards and rapidly mixed with the surrounding oxygenated seawater when the ciliate started to beat its cilia. In both species rapid stalk contraction and subsequent slow extension enhanced the mixing of oxygenated and deoxygenated, H2S-containing seawater; the feeding currents (toroidal vortices) drew the surround- ing seawater within reach of the zooid's external surface at high speed. It is suggested that this advective fluid transport supplies the ectobiotic bacteria with O2 and H2S simultaneously. The high fluid velocity may cause a decrease in cell boundary layer thickness, thereby enhancing rates of nutrient uptake by the ectobiotic bacteria.
On-line technique for preparing and measuring stable carbon isotope of total dissolved inorganic carbon in water samples (δ 13 CTDIC)

A fast and completely automated procedure is proposed for the preparation and determination of δ 13 C of total inorganic carbon dissolved in water (δ 13 CTDIC). This method is based on the acidification of water samples transforming the whole dissolved inorganic carbon species into CO2. Water samples are directly injected by syringe into 5.9 ml vials with screw caps which have a pierciable rubber septum. An Analytical Precision «Carbonate Prep System» was used both to flush pure helium into the vials and to automatically dispense a fixed amount of H3PO4. Full-equilibrium conditions between produced CO2 and water are reached at a temperature of 70°C (± 0.1°C) in less than 24 h. Carbon isotope ratios ( 13 C/ 12 C) were measured on an AP 2003 continuous flow mass spectrometer, connected on-line with the injection system. The precision and reproducibility of the proposed method was tested both on aqueous standard solutions prepared using Na2CO3 with δ

The concept of Faltings’ local-global principle for the in dimension < n of local cohomology modules over a Noetherian ring R is introduced, and it is shown that this principle holds at levels 1, 2. We also establish the same principle at all levels over an arbitrary Noetherian ring of dimension not exceeding 3. These generalize the main results of Brodmann et al. in [8]. Moreover, as a generalization of Raghavan’s result, we show that the Faltings’ local-global principle for the in dimension < n of local cohomology modules holds at all levels r ∈ N whenever the ring R is a homomorphic image of a Noetherian Gorenstein ring. Finally, it is shown that if M is a finitely generated Rmodule, a an ideal of R and r a non-negative integer such that aH a(M) is in dimension < 2 for all i < r and for some positive integer t, then for any minimax submodule N of H a(M), the R-module HomR(R/a, H r a(M)/N) is finitely generated. As a consequence, it follows that the associated primes of H a(M)/N are finite. This generalizes the main results of Brodmann-Lashgari [7] and Quy [24].
Effects of agricultural and urban impacts on macroinvertebrates assemblages in streams (Rio Grande do Sul, Brazil)

This study evaluates the effects of agricultural and urban activities on the structure and composition of benthic communities of streams in the state of Rio Grande do Sul, Brazil. Benthic macroinvertebrates were collected in streams influenced by urbanization and agriculture and in streams with no anthropogenic disturbances (reference streams). Organism density was superior in urban streams when compared with streams in the other two areas. The taxonomic richness and Shannon diversity index were higher in reference streams. The benthic fauna composition was significantly different among land uses. The classification and ordination analyses corroborated the results of variance analyses demonstrating the formation of clusters corresponding to streams with similar land use. Seasonality was also found to influence the benthic community, though in a lesser degree than land use.
THE EFFECTS OF PROTEIN SUPPLEMENTATION ON BITTERWEED TOXICOSIS IN LAMBS

This study determined if a supplemented protein diet high in escape protein or consisting of sulfur-containing amino acids would reduce the likelihood of bitterweed (Hymenoxys odorata DC) toxicosis. Forty recently weaned Rambouillet lambs were used with eight lambs randomly allocated to each treatment. They were placed in individual pens and allowed a seven-day adjustment period. Lambs were fed alfalfa pellets at 2.5% body weight, their respective treatment diet, and bitterweed. Treatments received either a (1) cottonseed meal (CSM), (2) CSM and Distiller’s Dried Grain (DDG), (3) soybean meal (SBM), or (4) SBM and DDG-based supplement. Treatment 5 received only alfalfa pellets. All supplements were isonitrogenous (37%), and lambs were fed enough supplement and alfalfa to achieve 150 g of growth per day. Bitterweed was offered immediately after supplemental diets for one hour daily for 15 days. Intake of supplemental diets, bitterweed, and alfalfa were measured on an individual animal basis. Lambs fed the SBM-based supplement ate more (P < 0.05) bitterweed than lambs fed alfalfa alone. Other supplemental diets did not improve bitterweed intake. None of the lambs from any treatment exhibited signs of toxicosis. Producers should consider feeding a SBM-based supplement to reduce the likelihood of bitterweed toxicosis in sheep.
