We investigate correlations between geomagnetic activity indices, theNorth Atlantic Oscillation (NAO), and stratospheric geopotentialheights. It is shown that the correlation between the geomagnetic indexAp and the NAO index is high and significant since about 1970, that itis significant during winter only, that it was not significant beforeabout 1970, and that the correlations are dominated by qu

OBJECTIVE: To assess prevalence figures for psychiatric disorders among institutionalized adolescents due to behavioural problems and/or delinquency. METHOD: Participants were recruited from consecutive referrals to/or treated at two Swedish adolescent units, SIS1 (n = 60) and SIS2 (n = 70) with ranging age of 12-20.3 years (mean age = 16.2; SD = 1.8) during 1 year. Clinical and diagnostic info

In physical therapy the clinical assessment Body Awareness Scale-Health (BAS-H) focusing on the quality of movements and movement behaviour has previously been studied for validity. The aim of this study was to address the inter-rater reliability and test-retest reliability in three groups. The groups assessed were: patients in psychiatric care with eating disorders (n = 26), patients in rehabilit

The pseudo-rapidity dependence of the elliptic flow at various excitation energies measured by the PHOBOS Collaboration in Au+Au collisions at RHIC is one of the surprising results that has not been explained before in terms of hydrodynamical models. Here we show that these data are in agreement with theoretical predictions based on perfect fluid hydrodynamics. We also show that these PHOBOS data

Endocannabinoids exert an important neuromodulatory role via presynaptic cannabinoid CB1 receptors and may also participate in the control of neural cell death and survival. The function of the endocannabinoid system has been extensively studied in differentiated neurons, but its potential role in neural progenitor cells remains to be elucidated. Here we show that the CB1 receptor and the endocann

Purpose: To investigate the potential of functional magnetic resonance imaging (fMRI) at 3T as a clinical tool in the preoperative evaluation of patients with intracranial tumors. High magnetic field strength such as 3T is of benefit for fMRI because signal-to-noise ratio and sensitivity to susceptibility changes are field-strength-dependent. Material and Methods: Twenty patients with tumors clos

A series of field studies at cold workplaces were initiated. This paper deals with the study at a telecommunication company and the main attention is paid to the thermal responses of the feet and footwear performance. The study was carried out in February. Eight male workers were the subjects. They were selected among volunteers who carried out various jobs on high masts on four different days. Th

In companies that constantly develop new software releases for large markets, there continually arrive new requirements, written in natural language that may affect the development work. Before any decision is made about the requirements, these must be analysed and understood, and related to the current set of implemented and queued requirements. This task is time-consuming owing to the high inflo

En produkts livscykel kan sällan förläggas till en plats eller ett land. Många produkter har helt eller delar av sitt ursprung i andra länder eller till och med världsdelar. Produktkedjan blir på det sättet mer eller mindre internationell i sina olika faser, vilket leder till konsekvensen att andra länders, EU:s eller andra överstatliga organs produktpolitik får betydelse för produkter som produce

Autooxidation of five polyphenols representing range of different hydrophobicities (catechin gallate (CG), (-) catechin((-)C), epicatechin (EC), epigallocatechin gallate (EGCG) and epigallocatechin (EGC)) in three different aqueous solutions: molecular solution, micellar solution (Tween-20) and liposomal dispersion (soybean lecithin) was monitored by HPLC. The rate of oxidation of the five polyphe

The reactions between galena and synthetic lead(II) sulphide powders, and potassium alkylxanthates have been studied in aqueous, acetone and acetonitrile solutions. Acetone and acetonitrile have been used since potassium and lead(II) alkylxanthates are soluble in these solvents. Qualitative analysis of the alkylxanthate species present on the surfaces of galena and synthetic lead(II) sulphide afte

Detta arbete behandlar tillväxten hos enkelarmerade betongkonstruktioners bärförmåga, speciellt under vinter fram till formgivning. Arbetet är uppdelat i 3 delar. I den första studeras betongens hållfasthetstillväxt vid olika härdningstemperaturer. I den andra delen bestäms brottlasten hos 30 betongbalkar och 6 betongväggar. I den tredje delen beräknas temperaturutvecklingen hos betongbalkar.

The repressor activator protein 1 (RAP1) plays a role in telomere structure and function inS. cerevisiae. Here, the RAP1 homologue was identified and cloned from the budding yeast Saccharomyces castellii (scasRAP1). The scasRAP1 gene encodes a protein of 826 amino acids and shares an overall high degree of similarity with the S. cerevisiae RAP1 (scerRAP1). We demonstrate that the scasRAP1 is able
