The exclusive H-2 (He-3, t)2p reaction has been studied at 2 GeV for energy transfers up to 500 MeV and triton angles up to 3.4degrees. The protons were measured in the large acceptance magnetic detector DIOGENE, in coincidence with the forward tritons detected in a dedicated magnetic arm. The energy transfer spectra extend well above the pion threshold. However, in the region of Delta excitation,

Popular Abstract in Swedish Identifiering av ärftlig äggstockscancer har stor klinisk relevans för att förhindra nya tumörer hos individen och i familjen. Möjligheten att förhindra bröstcancer i BRCA familjer genom kontrollprogram och profylaktisk kirurgi är välkänd, medan möjligheten att förhindra tarmcancer och livmodercancer i HNPCC familjer är mindre känd. Studierna i denna avhandling har kunnOvarian cancer is a leading cause of gynecological cancer death and in Sweden nearly 700 cases are diagnosed annually. Ovarian cancer has one of the highest frequencies of hereditary cancer. This thesis focuses on estimates of the contribution of hereditary breast and ovarian cancer (HBOC) and hereditary nonpolyposis colorectal cancer (HNPCC) to the development of ovarian cancer and investigates t

Popular Abstract in Swedish Denna studie är ämnad åt att undersöka joniseringsprocessen i gaser, både teoretiskt och experimentellt. Arbetet är speciellt riktat mot att utöka förståelsen för detta fenomen i förbränningsrummet av en förbränningsmotor. Den intensiva joniseringsprocessen som uppstår till följd av den antändande gnistan har studerats såväl som den svagare joniseringsprocessen som är rThe processes that govern the formation, existence and consumption of ions in gases have been studied both experimentally and theoretically. The aim of the work is targeted at increasing the understanding of these phenomena in the working gases inside an engine. Both the cause and the application of ionized gases inside the cylinder of a spark ignited (SI) engine has been studied. The spark disch

The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow upsilon(2)(eta)), as determined recently by the PHOBOS experiment for Au + Au collisions at root(S)NN = 130 and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of upsi

Xanthine derivatives are known to accelerate mucociliary transport in the lower airways, probably by preventing degradation of cyclic adenosine monophosphate (cAMP) and thereby increasing its intracellular concentration. The purpose of this study was to investigate the effects of cAMP on mucociliary activity in the upper airways. The effect on the mucociliary activity in the rabbit maxillary sinus

Receptors for the neurotransmitter and neuroendocrine peptides, vasoactive intesinal peptide (VIP) and secretin, both belong to the Type B subfamily of G-protein-coupled receptors. This group is evolutionally as well as structurally distinct from the much larger Type A, or rhodopsin-type, subfamily. We have mapped the ligand-activating epitopes of the human VIP1 receptor by the use of hybrid recep

Three issues are considered in this report —are assimilation and coarticulation the same process or different, are they achieved by feature spreading or by coproduction, and what level or levels of neuromotor planning or production do they represent? Tongue gestures analysed from an X-ray motion film of Bulgarian speech are presented as examples of what the tongue is made to do in speech and of ho

A rapid and sensitive assay was developed for the detection of amphetamine in plasma and urine. The method relies on the principle of competitive ELISA (enzyme-linked immunosorbent assay). A flow microchip with a total volume of 7 µL was used for the development of a chemiluminescent ELISA technique. Solutions, samples, and the chemiluminescence substrate were injected by a flow system, and a phot

OBJECTIVE - To study cross-sectional associations of dietary fiber intake with insulin resistance, insulin secretion, and glucose tolerance in a population at high risk for type 2 diabetes. RESEARCH DESIGN AND METHODS - The subjects consisted of 248 male and 304 female adult nondiabetic relatives of patients with type 2 diabetes. Dietary intake was measured by means of two 3-day food records. Asso

To investigate whether rat hippocampal neurogenesis varies with strain and gender, the authors examined proliferating progenitor cells and their progeny in young male and female Sprague-Dawley (SD) and spontaneously hypertensive rats (SHR) using the thymidine analog bromodeoxyuridine (BrdU) combined with immunohistochemistry for the neuronal marker Calbindin D28k and glial fibrillary acidic protei

The dimeric nonprenylated acylphloroglucinol semimyrtucommulone (6) was obtained from the leaves of. myrtle (Myrtus communis) as a 2:1 mixture of two rotamers. The known trimeric phloroglucinol myrtucommulone A (1) was also isolated and characterized spectroscopically as a silylated cyclized derivative (5). Myrtucommulone A showed significant antibacterial activity against multidrug-resistant (MDR

The contribution of this paper is a time-frequency domain speech presence detection method that classifies power bins in the time-frequency domain as containing speech or not. An initial decision rule is based on ratios between optimally time-smoothed signal-plus-noise periodograms and weighted noise periodogram estimates, obtained from minimum statistics as proposed by Martin [1]. The initial dec

The high spin structures in Nb-86 are analyzed using the cranked Nilsson-Strutinsky model. Energy versus spin curves as well as deformations and electric transition quadrupole moments are considered. It is concluded that different single-particle parameters compared with the standard values lead to better agreement with recent experimental results.

gamma -carboxylated polypeptides were detected in the human kidney by immunohistochemistry with a monoclonal antibody (M3B) specific for gamma -carboxyglutamyl residues. An similar to 70-kDa gamma -carboxylated protein, subsequently identified as prothrombin, was isolated from the intracellular compartment of cultured human embryonic kidney (HEK293) cells by immunoaffinity chromatography on M3B-co
