Mycket höga trapphus för utrymning kan trycksättas utan sektionering för att förhindra att brandgaser kommer in i trapphuset. Denna nya metod bygger på trapphusets ej försumbara strömningstekniska tryckfall och att trapphuset genomströmmas av ett flöde utöver det normala läckflödet som krävs för trycksättningen.
Environmental models are important tools; however uncertainty is pervasive in the modeling process. Current research has shown that understanding and representing these uncertainties is critical when decisions are expected to be made from the modeling results. One critical question has become: how focused should uncertainty intervals be with consideration of characteristics of uncertain input dat
Induction of altered phenotypes during development in response to environmental input involves epigenetic changes. Phenotypic traits can be passed between generations by a variety of mechanisms, including direct transmission of epigenetic states or by induction of epigenetic marks de novo in each generation. To distinguish between these possibilities we measured epigenetic marks over four generati
Protamines are the most abundant nuclear proteins and alterations in their expression have been described in infertile patients. Also, protamine haplo-insufficient mice have been described as infertile. Therefore, the protamine 1 and 2 genes have been considered important candidates in different mutational studies. In this article, we review all published articles related to protamine gene mutatio
This thesis is devoted to fundamental aspects, and to spectroscopic applications of radiative properties in free atoms and ions, as well as in ions doped into crystals. Using the time-resolved laser-induced fluorescence technique, measurements of radiative lifetimes for rare earth elements have been performed in neutral Pr, Nd, Tm, and in singly ionized Sm, Er, Nd, Tm, Yb, as well as in doubly io
Purpose: To investigate the predictive capacity of a new method for sound spectrum analysis of Doppler signals recorded from the umbilical artery in high-risk pregnancies. Material and Methods: The retrospective study comprised 127 pregnant women with various pregnancy complications between 23 and 39 gestational weeks. Umbilical artery blood flow velocity waveforms were recorded with Doppler ultra
Elevated γ-Glutamyltransferase serum levels are associated with increased risk of overall cancer incidence and several site-specific malignancies. In the present prospective study we report on the associations of serum γ-Glutamyltransferase with the risk of breast cancer in a pooled population-based cohort considering established life style risk factors.
Abstract Objective. To describe the surgical complication rate of open partial nephrectomy (OPN) in patients with renal tumours, and to report the oncological long-term outcome in unilateral renal cell cancer patients subjected to this procedure, from a medium patient volume urological centre. Material and methods. Data from all patients (n = 89) subjected to OPN for proven or suspected renal cell
This paper describes a CMOS current-folded direct digital RF quadrature modulator, which uses two 10-bit linear interpolation current steering digital-to-analog converters (DACs) and two current-folded double-balanced mixers. The attenuation of the DAC image components is significantly increased with linear interpolation, and the reconstruction filter is therefore eliminated. The DAC baseband diff
