A new laminar flamelet model is presented for Large Eddy Simulation ( LES) of premixed turbulent combustion. The model uses a marker field S+ to capture the flame. Compared to previous work on marker fields, a modification was introduced to simplify the boundary conditions. Although the scalar S+ is smooth in space, it allows describing steep flame fronts. The S+ equation captures the laminar or t

Purpose A Japanese randomized trial showed superior survival for patients with extensive-disease (ED) small-cell lung cancer (SCLC) receiving irinotecan plus cisplatin compared with etoposide plus cisplatin. The present trial evaluated the efficacy of irinotecan plus carboplatin (IC) compared with oral etoposide plus carboplatin (EC). Patients and Methods Patients with ED SCLC were randomly assign

This study investigates exposure to polybrominated diphenyl ethers (PBDEs) and tetrabromobisphenol A (TBBPA), which are used as flame retardants in electronic equipment, in a group of technicians with intense computer work. Thirteen PBDE congeners and TBBPA were quantified in serum from 19 computer technicians. Previously investigated groups of hospital cleaners with no computer experience, and cl

Fine-needle aspiration (FNA) features in 10 angioleiomyomas (ALM) were evaluated and correlated to histological features and clinical data. The tumors developed in the skin or subcutaneous tissue of the lower extremities (eight), the shoulder (one), and the lower arm (one). Eight tumors were painful or tender. Cytological specimens showed moderate or sparse cellularity. The most frequent findings

A natural summer phytoplankton community from the Gullmar Fjord (Skagerrak, Swedish west coast) was diluted 10 times with filtered seawater in twelve 300-dm(3) polyethylene cylinders. Nutrients were added to produce two different molar ratios of nitrogen to silicon (N/Si 3.2/3.2 mu M=1 and 12.8/3.2 mu M=4). Three cylinders of each nutrient treatment were carefully mixed while the other three of ea

Background: Previous studies support a role of oxygen-free radicals in the development of congestive heart failure (CHF). The aim of this study was to investigate whether lipid peroxidation is increased in CHF patients on modem pharmacological therapy and whether there is a positive correlation between plasma levels of markers of lipid peroxidation and severity of heart failure (HF). Plasma malond

We followed a population-based cohort of 5696 women, 32 - 38 years of age, by registry linkage with cytology and pathology registries during a mean follow-up time of 4.1 years to assess the importance for CIN2 + development of type-specific HPV DNA positivity at baseline. HPV 16, 31 and 33 conveyed the highest risks and were responsible for 33.1, 18.3 and 7.7% of CIN2 + cases, respectively. Women

OBJECTIVES: The aim of this study was to evaluate the applicability of total plasma protein adducts (TPPA) of 2 sensitizing low-molecular-weight allergens, hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA), as biomarkers of long-term exposure. METHODS: Urine samples from occupationally exposed workers were analyzed for the levels of urinary metabolites of HHPA and MH

Adrenocorticotrophic hormone (ACTH) at pharmacological dosage has marked lipid-lowering effects that may have therapeutic implications. The rationale behind the present investigation was the possible use of ACTH as a lipid-lowering replacement for steroids. Thirty-two healthy individuals were randomly divided into four groups of 8 each. Three ACTH groups received different doses of ACTH(1-24) intr

The Hyttsjo granites occur in the extensively mineralised Langban-Nordmark area in the westernmost part of the Bergslagen ore province. They have been classified as late Svecokarelian granites due to their homogeneous and generally isotropic appearance in addition to a WR Rb/Sr age. Moreover, they have been considered as possible candidates for supplying essential metals to epigenetic mineralisati

A thermoseparating aqueous two-phase system for extraction of a recombinant cutinase fusion protein from Escherichia coli homogenate has been scaled up to pilot scale. The target protein ZZ-cutinase-(WP)4 was produced in a fed batch process at 500 l to a concentration of 12% of the total protein and at a cell concentration of 19.7 g l-1. After harvest and high-pressure homogenisation a first extra

Polyamine depletion causes S phase prolongation, and earlier studies indicate that the elongation step of DNA replication is affected. This led us to investigate the effects of polyamine depletion on enzymes crucial for Okazaki fragment maturation in the two breast cancer cell lines MCF-7 and L56Br-C1. In MCF-7 cells, treatment with N(1),N(11)-diethylnorspermine (DENSPM) causes S phase prolongatio

The adsorption of water on two silicon surfaces [reconstructed planar (100)2×1 and single domain stepped (100)2×1 cut 5° towards (011)] was studied using low-energy electron diffraction and digital imaging electron stimulated desorption ion angular distributions (ESDIAD) as a function of temperature (145–700 K) and coverage. Water has been shown previously to chemisorb dissociatively to form surfa

Study objective: The principle of equity aims to guarantee allocation of healthcare resources on the basis of need. Therefore, people with a low income and persons living alone are expected to have higher healthcare expenditures. Besides these individual characteristics healthcare expenditure may be influenced by country of birth. This study therefore aimed to investigate the role of country of bi

The ECG is the key clinical test available for the emergency determination of which patients who presenting with acute coronary syndromes indeed have acute myocardial ischemia/infarction. Because typically the etiology is thrombosis, the correct clinical decision regarding reperfusion therapy is crucial. This review follows the efforts of an AHA working group to develop new standards for clinical

The incidence and intensity of hypoxic waters in coastal aquatic ecosystems has been expanding in recent decades coincident with eutrophication of the coastal zone. Worldwide, there is strong interest in reducing the size and duration of hypoxia in coastal waters, because hypoxia causes negative effects for many organisms and ecosystem processes. Although strategies to reduce hypoxia by decreasing
