Popular Abstract in Swedish Huvudsyftet med studien har varit att ta fram matematiska samband för dimensionering av processutrustning – dimensionering är ett klassiskt ingenjörsproblem. Korrekt dimensionering är viktig för att utrustningen skall fungera tillfredsställande och dessutom inte resultera i onödiga investerings- och driftskostnader. Den matematiska modell (en uppsättning ekvationer) soA study concerning closure relations pertinent to the design of sorption equipment of absorption heat pumps has been undertaken. Specifically, thermosiphon and vertical falling film arrangements were studied. For the thermosiphon, experimental data on the void fraction, the friction and orifice pressure drops, and the heat transfer coefficient at sub-atmospheric pressures were obtained for vapori

The aim of this study was to describe first-time mothers' views of satisfaction with their first encounter with the nurse, in order to investigate differences between home visits and clinic visits and between high/middle and low socioeconomic classification (SEC). A nation-wide postal questionnaire sent to 800 first-time mothers yielded the data for statistical analysis. Data were collected using

Eighteen groups of guinea pigs were exposed to a simulated impact noise for periods of 1.5-24 h. The peak level was kept constant at 131.5 dB and the repetition rate was varied to give seven different equivalent levels (Leq) between 96 and 117 dB. The auditory thresholds were assessed by electrocochleography after 1 month and compared with those of a control group. Significant damage occurred even

Background: Several countries are discussing new legislation on the ban of smoking in public places, and on the acceptable levels of traffic-related air pollutants. It is therefore useful to estimate the burden of disease associated with indoor and outdoor air pollution. Methods: We have estimated exposure to Environmental Tobacco Smoke (ETS) and to air pollution in never smokers and ex-smokers in

Infrared and collinear safe event shape distributions and their mean values are determined in e(+)e(-) collisions at centre-of-mass energies between 45 and 202GeV. A phenomenological analysis based on power correction models including hadron mass effects for both differential distributions and mean values is presented. Using power corrections, alpha(s) is extracted from the mean values and shapes.

Recent research has emphasised the role of trade in productivity growth. The purpose of the present paper is to investigate how regional integration, and the different treatment of member and non-member imports, affects the relation between imports and productivity growth. We focus on the European Union and find intra-union imports to have more of an effect on total factor productivity growth than

BACKGROUND: Multifocal electroretinogram (mfERG) has the power to discriminate between localized functional losses and overall retinal changes when evaluating retinal injury. So far, full-field ERG has been the gold standard for examining retinal ischemia and the effects of different neuroprotectants in experimental conditions. The aim of the present study was to establish mfERG, with simultaneous

Stroke is the third most common cause of death in developed countries, exceeded only by coronary heart disease and cancer. There is substantial scientific literature on the association between occupational exposures and coronary heart disease, but much less is known about stroke. This systematic critical review was performed to assess the strength of evidence for causal associations between chemic

No study has investigated the predictive validity and cut-off scores in diagnostic tests for falls used in in-home assessment in frail older people. The objective was to investigate the predictive validity for falls in the Downton Fall Risk Index (DFRI), Timed Up and Go (TUG) and Romberg test (RT) used in in-home assessment of frail older people (65+ years). Data on the diagnostic tests were colle

The specification and differentiation of dentate gyrus granule neurons in the hippocampus require temporally and spatially coordinated actions of both intrinsic and extrinsic molecules. The basic helix-loop-helix transcription factor Neurogenin2 (Ngn2) and NeuroD1 are key regulators in these processes. Based on existing classification, we analyzed the molecular events occurring during hippocampal

A rapid screening procedure for characterization of lipase selectivities using microwaves was developed. The rate of reaction of various commercial lipases (porcine pancreas, Mucor miehei, Candida rugosa, Pseudomonas cepacia) as well as lipases from laboratory isolates-Bacillus stearothermophilus and Burkholderia cepacia RGP-10 for triolein hydrolysis was 7- to 12-fold higher in a microwave oven a
