Aims. We analyze a sample of tens of thousands of spectra of halo turnoff stars, obtained with the optical spectrographs of the Sloan Digital Sky Survey (SDSS), to characterize the stellar halo population "in situ" out to a distance of a few tens of kpc from the Sun. In this paper we describe the derivation of atmospheric parameters. We also derive the overall stellar metallicity distribution base

PIP: The first generation high-dose ( 80 mcg estrogen) oral contraceptives (OCs) were associated with an increased risk of deep venous thrombosis (DVT). So manufacturers removed the high-dose OCs and first replaced them with OCs with 50 mcg estrogen, resulting in a lower incidence of thromboembolic events (40 vs. 20/100,000 users). When they introduced an even lower dose OC (30 mcg estrogen), the

OBJECTIVES: To obtain knowledge on male reproductive toxicity of inorganic lead at current European exposure levels and to establish lowest adverse effect levels, if any. METHODS: A cross sectional survey of the semen of 503 men employed by 10 companies was conducted in the United Kingdom, Italy, and Belgium. The mean blood lead concentration was 31.0 microg/dl (range 4.6-64.5) in 362 workers expo

Background: Natural antibodies specific for phosphorylcholine (anti-PC) have been implicated as protective factors in atherosclerosis. We herein determined the relationship between IgM anti-PC and incidence of cardiovascular disease (CVD). Methods: We studied 349 incident cases (200 men) of first events of CVD (coronary heart disease (CHD; n = 203 or ischemic stroke; n = 146) and 693 age- and sex-

Att dika skogar till förmån för bland annat bättre tillväxt kan påverka och förändra faktorer som marktemperatur och markfuktighet vilka är de viktigaste faktorerna för markrespirationen och flödet av koldioxid till atmosfären. Markrespirationen svarar för huvuddelen av koldioxidflödet till atmosfären från ett markbundet ekosystem. Koldioxid är en viktig växthusgas och små förändringar av flödet kDitching forests in favor of for example better tree growth can affect and change factors such as soil temperature and soil moisture. Those are the most important factors for soil respiration and the flow of carbon dioxide (CO2) into the atmosphere. The soil respiration accounts for the major flux of CO2 to the atmosphere from the terrestrial ecosystem. CO2 is an important greenhouse gas and small

2 Abstract The paper focuses on evaluating the most performant Value-at-Risk models from the perspective of financial institutions. A number of 18 VaR methodologies were used for this purpose, comprising of parametric and non-parametric methods, some of which include time-varying volatilities estimated by means of GARCH and asymmetric GARCH models. All methods were applied on real P/L data extract

Experimental data on precipitation chemistry were collected at a semi-arid savanna in Senegal (Dahra) in 2013, 2014 and 2017. The chemical composition of precipitation was analyzed for inorganic and organic ions, using ionic chromatography. The pH values of precipitation range from 4.50 to 8.50 with 89% of the samples having basic pH. The composition of precipitation was controlled by four source

PURPOSE: The deep breathing test (DBT) is a sensitive test of cardiovagal function. The aim of this study was to explore associations between physical activity and sedentary time, measured by accelerometer, and autonomic function, using DBT.METHODS: In the Swedish Cardio-Pulmonary bioImage Study, men and women aged 50-64 were randomly invited from the general population. A total of 4325 subjects w

This project involved the testing and establishment of a base combustion procedure for the newly acquired Raddec Gen IV PYROLYSER and focused on the optimization and correction of the laboratory’s previous liquid scintillation counting (LSC) procedure using the Hidex 300 SL. The pyrolyser was verified to be operational and achieve satisfactory and consistent recoveries across the 6 combustion tub

Gasoline partially premixed combustion (PPC) is a potential strategy to achieve high engine efficiency, as well as low NOx and soot emissions. But the in-cylinder combustion process of PPC is not well understood. In this paper, multiple optical diagnostics are applied to investigate the PPC ignition and flame development in a light-duty optical engine under single-injection condition. For the inje

More than 40 years of re-vegetation using mainly xerophytic shrubs Artemisia ordosica Krasch. and Caragana korshinskii Kom. at Shapotou Desert Experimental Research Station near Lanzhou, China has resulted in established dwarf-shrub and herbaceous cover on sand dunes. Precipitation, as the sole source of water replenishment in the semiarid area, plays a pertinent role in sustaining the desert ecos

In the study presented in this paper, the effect of different vehicle driving cycles on the pneumatic hybrid has been investigated. The pneumatic hybrid powertrain has been modeled in UT-Power and validated against experimental data. The GT-Power engine model has been linked with a MATLAB/simulink vehicle model. The engine in question is a single-cylinder Scania D12 diesel engine, which has been c

Popular Abstract in Swedish Arbetet har bestått av att dels experimentellt samt dels med hjälp av matematiska modeller undersöka och kartlägga förloppen för nya samt "gamla" metoder att rena rökgaser från kol- och olje eldade kraftverk.Combustion of fossil fuels is the main source for emissions of sulfur dioxide and nitrogen oxides. Emission regulations and the growing environmental awareness will make great demands upon cost-effective deSO2 and deNOx techniques in the future. Many of the techniques available today have been on the market for a long time, however, most of them still have a potential for improvement. To be able t

I rapporten utvärderas the Waste Management Planning System (WAMPS), som är ett förenklat LCA-baserat verktyg för att jämföra avfallsscenarion utifrån miljömässiga aspekter. Syftet med studien var att hitta bristfälliga områden i modellen som behöver förbättras/uppdateras. Utvärderingen genomfördes genom att jämföra modellens struktur med liknande modeller samt genom att jämföra de resultat som beThis report evaluates the model Waste Management Planning System (WAMPS), which is an LCA-based tool used to compare different waste management scenarios from an environmental perspective. The aim of the study was to find deficient areas in the model that needed to be updated or improved. The evaluation was conducted by comparing the structure of the model to the structure of similar models and by

Detailed weather predictions are of interest e.g. to protect humans and society from damages caused by extreme weather. To do this today’s forecast models need higher resolution, i.e. less distance between measure points. So-called non-hydrostatic models are used when this distance decreases. The development of this type of models has progressed during the past 20 years due to more powerful comput

Agriculture is an essential economic activity which sustains the livelihood of millions of people around the world. Maize is one of the most grown, consumed and traded cereals in the world mostly because of its adaptability to varied environmental conditions. Maize farming depends on climatic factors like temperature, rainfall and radiation to thrive but this also means that it is very susceptible

The assessment of effects of anthropogenic disturbance on biodiversity (BD) and ecosystem services (ES) and their relationships are key priorities of the Intergovernmental Panel for Biodiversity and Ecosystem Services. Agricultural landscapes and their associated BD provide multiple ES and it is crucial to understand how relationships between ES and BD components change along gradients of landscap
