The dynamic mechanical properties and acoustic damping of polyurethane (PU) foams loaded with a hyperbranched polymer (HBP) have been studied. The results show a significant modulus enhancement parallel to an increased vibration damping in the low frequency range of approximate to 1 Hz with increased amount of HBP. Furthermore, an increased acoustic damping in the frequency interval of 500-1600 Hz
Companies adopt different rationales for purchasing in order to make production processes as efficient as possible. This paper presents the results of an investigation into how purchasing strategies can vary between companies and countries. Two industrialised building companies, one in Sweden and one in Australia, were the objects of study. The purpose was to compare and understand the rationale b
Recently, fish farming instead of traditional agriculture has been seen as a way to increase agricultural profits from saline affected land. Concerns, however, have been raised that fish farming may increase the salinity problems. In the salinity affected soils of the El-Salam canal project area in Egypt, farmers are giving tip traditional farming for fish farming due to possibilities to increase
The humoral Idiotypic Network consisting of antibodies and their anti-idiotypic antibodies (anti-Id) can be temporarily upset by antigen exposure. In the healthy immune response the original equilibrium is eventually restored through counter-regulatory mechanisms. In certain autoimmune diseases however, autoantibody levels exceed those of their respective anti-Id, indicating a permanent disturbanc
Context: Castration-resistant prostate cancer (CRPC) refers to patients who no longer respond to surgical or medical castration. Standard treatment options are limited. Objective: To review the concepts and rationale behind targeted agents currently in late-stage clinical testing for patients with CRPC. Evidence acquisition: Novel targeted therapies in clinical trials were identified from registri
To improve the biologic understanding of the Polycystic Ovarian Syndrome (PCOS) condition by examining the circadian variation and relationship between Anti Müllerian Hormone (AMH), gonadotropins and ovarian steroids in PCOS patients compared to normally ovulating and menstruating women. By comparing the pattern of co-variation between AMH and Luteinizing Hormone, two compounds closely linked to h
Angiogenesis is one of the hallmarks of breast cancer. The status of angiogenesis is important in therapy choice. Spider telangiectasias (telangiectasias) may reflect an increased ability to form vessels. Our first aim was to identify patient and tumor characteristics associated with the occurrence of telangiectasias at the time of breast cancer diagnosis. The second aim was to study the overall s
Survival following a diagnosis of multiple myeloma (MM) varies between patients and some of these differences may be a consequence of inherited genetic variation. In this study, to identify genetic markers associated with MM overall survival (MM-OS), we conduct a meta-analysis of four patient series of European ancestry, totalling 3,256 patients with 1,200 MM-associated deaths. Each series is geno
The overall aim was to describe and compare functional ability and health complaints of older people receiving municipal care in relation to housing and informal care, and factors associated with medical health care, municipal care and informal care. Further, the aim was to investigate agreement in needs assessments between personnel and older people and to investigate care satisfaction and health
BACKGROUND/OBJECTIVES: Heavy alcohol drinking is a risk factor of colorectal cancer (CRC), but little is known on the effect of polymorphisms in the alcohol-metabolizing enzymes, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) on the alcohol-related risk of CRC in Caucasian populations. SUBJECTS/METHODS: A nested case-control study (1269 cases matched to 2107controls by sex, age, stu
Intracellular membrane fusion is coordinated by membrane-anchored fusion proteins. The cytosolic domains of these proteins form a specific complex that pulls the membranes into close proximity. Although some results indicate that membrane merger can be accomplished solely on the basis of proximity, others emphasize the importance of bilayer stress exerted by transmembrane peptides. In a reductioni
Suicide is a major global health problem imposing a considerable burden on populations in terms of disability-adjusted life years. There has been an increasing trend in fatal and attempted suicide in Iran over the past few decades. The aim of the current study was to assess overall, gender and social inequalities across Iran's provinces during 2006-2010.

The effects induced by Na deposited on furnace grown graphene on SiC(0001) and after subsequent annealing are investigated using LEEM, mu-LEED, mu-PES and XPEEM. Intercalation in between carbon layers and at the interface is observed to occur both on the 1 ML and 2 ML areas directly after Na deposition. Annealing at a temperature around 100 degrees C is found to strongly promote Na intercalation.
In this paper a count data regression model accounting for endogenous censoring with household specific censoring thresholds is presented. The presented modelling approach is utilized in an analysis of household choice of total number of nights to spend on monthly recreational trips. The empirical study reveals that the suggested approach is feasible and that accounting for endogenous censoring gi
Melangyna pavlovskyi (Violovitsh, 1956) has been found breeding in Denmark. The species is recorded from four localities on Zealand, and it is established on at least one of these. It is new to the European fauna. A redescription of M. pavlovskyi based on the external characters and an updated key to the NW European species of Melangyna are presented.
Background and purpose The Hansson Twin Hook (HTH) is an alternative to the lag screw in the treatment of trochanteric fractures. In osteoporotic bone, mechanical tests have indicated that the HTH has better fixation properties than the lag screw. We evaluated the fixation stability of the HTH in a large series of elderly patients with trochanteric fractures. Many surgeons were involved in assessm
We consider the following signaling game. Nature plays first from the set {1,2}{1,2}. Player 1 (the Sender) sees this and plays from the set {A,B}{A,B}. Player 2 (the Receiver) sees only Player 1’s play and plays from the set {1,2}{1,2}. Both players win if Player 2’s play equals Nature’s play and lose otherwise. Players are told whether they have won or lost, and the game is repeated. An urn sche
