In Sweden a fundamental development has recently taken place in the training of future senior fire brigade officers. There are two main changes: the training period has been substantially increased and the theoretical part upgraded to university curriculum level with final requirements corresponding to a university undergraduate degree. The new educational system reflects the changing and expandin
PDGF-C is a member of the platelet-derived growth factor (PDGF) family, which signals through PDGF receptor (PDGFR) alphaalpha and alphabeta dimers. Here we show that Pdgfc(-/-) mice die in the perinatal period owing to feeding and respiratory difficulties associated with a complete cleft of the secondary palate. This phenotype was less severe than that of Pdgfra(-/-) embryos. Pdgfc(-/-) Pdgfa(-/-
Patients-Seven patients with Barrett's metaplastic epithelium and oesophageal adenocarcinoma were investigated by means of laser induced fluorescence after low dose intravenous injection (0 . 35 mg/kg bw) of Photofrin (QLT, Vancouver, Canada). Laser induced fluorescence measurements were performed immediately after resection of the oesophagus. Methods-Laser induced fluorescence spectra were record
Results from a previous study showed that sexuality was negatively affected in females with untreated obstructive sleep apnea (OSA). Data are sparse on the long-term effects of nocturnal continuous positive airway pressure (CPAP) treatment on sexual difficulties and sexual distress in female patients with OSA.

Summary Standard sperm parameters have a limited power for prediction of the chance of natural conception. Recent studies have indicated that the sperm chromatin structure assay (SCSA) DNA fragmentation index (DFI), a measure for the fraction of sperms with DNA damage, is associated with fertility in vivo. The aim of this study was to evaluate the value of this parameter for prediction of infertil
Electric and magnetic currents are essential to describe electromagnetic-stored energy, and the associated antenna Q and the partial directivity to antenna Q-ratio, D/Q, for arbitrarily shaped structures. The upper bound of previous D/Q results for antennas modelled by electric currents is accurate enough to be predictive. This motivates us to develop the analysis required to determine upper and/o
Popular Abstract in Swedish Varför är arbetslösheten bland ungdomar i Sverige tre gånger högre än arbetslösheten bland 25-64 åringar? Har kontakter och nätverk betydelse för ungdomsarbetslösheten? Den tes som drivs i denna avhandling menar att kontakter i form av överbryggande socialt kapital har betydelse för ungdomars möjlighet att få jobb och att ungdomars brist på socialt kapital leder till atYouth unemployment in Sweden has reached record levels during the first decade of the 21st century. In 1970, the unemployment rate for 20-24 year olds was approximately 2%. Now, forty years later, this rate has risen to 20%. Relative youth unemployment (youth unemployment in relation to unemployment for the 25-64 year olds) has also risen. Today, the unem¬ployment rate for 20-24 year olds is three
We compared the differences in median age at spermarche among 11 ethnic minorities in 2010, estimated the trends regarding age at spermarche in different ethnic minorities from 1995 to 2010, and explored the association of spermarche with body mass index (BMI).
Basal-like breast cancer (BBC) is a subtype of breast cancer with poor prognosis1, 2, 3. Inherited mutations of BRCA1, a cancer susceptibility gene involved in double-strand DNA break (DSB) repair, lead to breast cancers that are nearly always of the BBC subtype3, 4, 5; however, the precise molecular lesions and oncogenic consequences of BRCA1 dysfunction are poorly understood. Here we show that h
It is well known that user proximity introduces absorption and impedance mismatch losses that severely degrade multiple-input multiple-output (MIMO) performance of handset antennas. In this work, we experimentally verified the potential of adaptive impedance matching (AIM) to mitigate user interaction effects and identified the main AIM gain mechanism in realistic systems. A practical setup includ
The finite element method is used to analyze the stability of a cantilever column resting on elastic foundation and subjected to an eccentric slave load at its free end. The analysis has been conducted according to Bernoulli-Euler and Timoshenko beam theories. Effects of the mass offset, coupling effects and damping has been taken into account.
