The notion of proportional fairness has recently gained considerable interest as a potential means for a fair allocation of bandwidth between the end nodes of demands in the networks carrying elastic traffic. The issue of proportionally fair allocation of bandwidth for the nominal state of the network has been studied before, both in the capacitated (link capacities given) and the uncapacitated (l
The aim of the study was to compare the subjective quality of life of persons with severe mental illness in inpatient settings and two types of supported housing, small congregate community residences and independent living with support. Seventy-six persons living in three types of housing were interviewed using the Lancashire Quality of Life Profile. Analysis showed no differences in subjective a
An anti-ERBB2 antibody, trastuzumab, has been shown to be highly efficient in the treatment of metastatic breast cancers overexpressing the ERBB2 gene. It has been suggested that overexpression and even amplification of ERBB2 may play a role in the development of prostate cancer. Here, we have analyzed gene copy number and expression of the ERBB2 gene in both androgen-dependent primary and metasta
Emissions of volatile organic compounds (VOCs) from mountain birches were measured in Abisko, northern Sweden. Mountain birches make up the majority of the tree biomass in Scandinavian high latitudes, a region subject to significant climate warming. The measurements were carried out in two growing seasons. The emissions of four branches, each from a different individual tree, were measured in June
A distinctive feature of BRCA1-linked breast cancers is that they typically do not express estrogen receptor-alpha (ERalpha). Previous investigation suggests that methylation of CpGs within the ERa promoter mediates repression of gene expression in some ERalpha-negative breast cancers. To determine if methylation of CpGs within the ERalpha promoter is associated with BRCA1-linked breast cancers, w
The phase behavior of aqueous mixtures of the "clouding" polymer ethyl(hydroxyethyl)cellulose (EHEC) mixed with colloidal particles and surfactants has been studied. These types of mixtures are important in many technical formulations. Two types of particles, polystyrene latex and silica, and two types of EHEC, nonmodified EHEC (N-EHEC) and hydrophobically modified EHEC (HM-EHEC), were studied. Th
We suggest a method that can be used for analysing an emergency response system. Both the literature and empirical findings indicate that response operations sometimes diverge from existing plans when adapting to an event and its consequences. The method, which aims at achieving a better understanding of emergency response management, adopts a systems perspective using various relationships that e
Insulin NPH (neutral protamine hagedorn) has for long been one of the most important therapeutic formulations for the treatment of diabetes. The protracted action profile of NPH formulations is gained from crystallizing insulin with zinc in the presence of the basic poly-arginine peptide protamine. In spite of its long history and successful use, the binding mode of the insulin-protamine complex i
The proper use and exchange of the right packaging-related information in a grocery supply chain is critical to achieve an efficient and responsive packaging logistics system. The use of well-defined packaging-related information that is available for all actors in the supply chain also facilitates an integrated and supply chain-orientated packaging development. The objective of this paper is to d
Recent results concerning the short-term growth response to salinity of the developing barley leaf are reviewed. Plants were grown hydroponically and the growth response of leaf 3 was studied between 10 min and 5 d following addition of 100 mM NaCl to the root medium. The aim of the experiments was to relate changes in variables that are likely to affect cell elongation to changes in leaf growth.
Objective To describe the effect of vaginal delivery with no clinically recognized sphincter tear on endosonographic anal sphincter morphology and sphincter pressure and to relate endosonographic results to anal sphincter pressure and anal incontinence score. Study design Thirty-two nullipara underwent anal endosonography and anal manometry in the third trimester of pregnancy, 2 weeks and 6 mon
MreB forms a cytoskeleton in many rod-shaped bacteria which is involved in cell shape determination and chromosome segregation. PCR-based and Southern analysis of various actinomycetes, supported by analysis of genome sequences, revealed mreB homologues only in genera that form an aerial mycelium and sporulate. We analysed MreB in one such organism, Streptomyces coelicolor. Ectopic overexpression
Objective - ADP plays an important role in platelet aggregation by activating P2Y(12) receptors. We assessed the hypothesis that P2Y(12) receptors are expressed in vascular smooth muscle cells (VSMC). Methods and Results - P2Y(12) receptor mRNA was found to have a high expression among the P2 receptors in human VSMC, significantly higher than the other 2 ADP receptors (P2Y(1) and P2Y(13), real-tim

The effect of some environmentally relevant factors including salinity, pH, and humic acids on the availability of bisphenol A (BPA) was evaluated by using the negligible-depletion solid-phase microextraction (nd-SPME) biomimetic method. With the variation of salinity (0-500 mM NaCl) and pH (5.0-8.5) of aqueous solutions, the partition coefficients of BPA between the nd-SPME fiber and the aqueous
