Multiple beta(-) decaying states in Re-194: Shape evolution in neutron-rich osmium isotopes
beta decays from heavy, neutron-rich nuclei with A similar to 190 have been investigated following their production via the relativistic projectile fragmentation of an E/A = 1 GeV Pb-208 primary beam on a similar to 2.5 g/cm(2) Be-9 target. The reaction products were separated and identified using the GSI FRagment Separator (FRS) and stopped in the RISING active stopper. gamma decays were observed
Free-carrier absorption in quantum cascade structures
We show that the free-carrier absorption in quantum cascade lasers (QCLs) is very small and radically different from the classical Drude result due to the orthogonality between the direction of the carrier free motion and the electric field of the laser emission. A quantum mechanical calculation of the free-carrier absorption and intersubband oblique absorption induced by interface defects, Coulom
Efficacy of preoperative radiochemotherapy in patients with locally advanced pancreatic carcinoma
Background. The optimal care for patients with unresectable, non-metastatic pancreatic adenocarcinoma (PAC) is debated. We treated 17 consecutive cases with preoperative radiochemotherapy (RCT) as a means for downstaging their tumours and compared outcome with 35 patients undergoing direct surgery for primarily resectable PAC during the same time period. Methods. The patients had biopsy proven, un

Binding of complement regulators to invasive nontypeable Haemophilus influenzae is not increased compared to nasopharyngeal isolates, but serum resistance is linked to disease severity.
The aim of the present study was to analyse the importance for non-typeable Haemophilus influenzae (NTHi) isolated from patients with sepsis (invasive isolates) compared to nasopharyngeal isolates from patients with upper respiratory tract infection to resist the complement-mediated attack in human serum and to correlate this to disease severity. We in detail studied and characterized cases of inv

Barriers faced by Ugandan university students in seeking medical care and sexual health counselling: a cross-sectional study
Background: Meeting the medical and sexual health care needs of young people is crucial for sustainable development. In Uganda, youth are faced with a number of challenges related to accessing medical care and sexual health counselling services. This study sought to investigate the barriers faced by Ugandan university students in seeking medical care and sexual health counselling. Methods: This st
Endoplasmic Reticulum Dynamic Structural Changes in Neurons: The Fission-Fusion Phenomena
Popular Abstract in Swedish Det endoplasmatiska retiklet (ER) är nödvändigt för proteinsyntes och posttranslationell proteinmodifiering. ER är också iblandat i cellstress och utgör den största intracellulära kalciumkällan i nervceller. Neuronalt ER bildar ett kontinuerligt nätverk som består av dels rörliknande förbindelser (tubules) och större cisterner. Att nätverket utgör en kontinuerlig lumen The endoplasmic reticulum (ER) is crucial for protein synthesis and protein maturation, is involved in cell stress and serves in neurons as the major intracellular Ca2+ store. Neuronal ER forms a continuous network of cisterns and tubules extending from soma to a subset of dendritic spines. The continuity of ER structure is important for maintaining ER basic functions and necessary for proteins an
Estimation of Nonhomogeneous and Multi-Section Twisted-Pair Transmission-Line Parameters
In emerging and future copper access networks, the trend goes towards exploiting higher transmission bandwidths on shorter twisted-pair cables. Methods to accurately determine relevant transmission-line parameters are a prerequisite to exploit the potential of these short-to-medium range access lines. In this paper, we propose a model-based space-frequency optimization approach initially developed

Potential influence of water level changes on energy flows in a lake food web
Large seasonal water-level fluctuations may influence isotopic signatures of primary producers and the types and amounts of these potential food sources accessible to aquatic fauna of Poyang Lake, the largest freshwater lake in China. In this study, the isotopic signatures of primary producers and consumers were determined, stable carbon and nitrogen isotope analysis and mixing models were combine

Adherence to physical activity recommendations and its associated factors: an interregional population-based study.
Though the influence of physical activity in preventing cardiovascular diseases is well documented, only a few comparative studies have determined the degree of adherence to physical activity recommendations among populations and identified the demographic, socioeco-nomic, behavioural and health-related factors associated with good compliance.

Ekologisk Marxism: att göra vänstern grön
För den spirande miljömedvetenheten på 1960-talet måste det har tett sig uppenbart att den socialistiska rörelsen – på båda sidor om verkliga och ideologiska murar – prioriterade sysselsättning och växande (privat och offentligt) konsumtionsutrymme långt före ekologiska hållbarhetsfrågor, och trots att miljöpolitik nu har lagts till andra politikområden har den prioritetsordningen knappast ändrats

Protein recognition via ion-coordinated molecularly imprinted supermacroporous cryogels
Molecular imprinting is a method for making selective binding sites in synthetic polymers using a molecular template. The aim of this study is to prepare lysozyme-imprinted supermacroporous cryogels which can be used for the purification of lysozyme (Lyz) from egg white. N-Methacryloyl-(L)-histiclinemethylester (MAH) was chosen as the metal-coordinating monomer. In the first step, Cu2+ was complex
Weight Suppression and Body Mass Index Interact to Predict Long-Term Weight Outcomes in Adolescent-Onset Anorexia Nervosa
Research on anorexia nervosa (AN) has emphasized the importance of low absolute body weight, but emerging research suggests the importance of also considering low body weight relative to an individual's highest premorbid weight (weight suppression; WS). Objective: We investigated whether body mass index and WS at lowest weight (BMI-LW and WS-LW) among adolescents with AN predicted BMI at 6-, 10-,
