Coupled cluster and density functional theory studies of the vibrational contribution to the optical rotation of (S)-propylene oxide

In a previous study (Chemical Physics Letters 2005, 401, 385) we computed the optical rotatory dispersion of (S)-propylene oxide in gas phase and solution using the hierarchy of coupled cluster models CCS, CC2, CCSD, and CC3. Even for the highly correlated CC3 model combined with a flexible basis set, the theoretical gas-phase specific rotation at 355 nm was found to be negative in contrast to the

Molecular basis for amyloidosis related to hereditary brain hemorrhage

The aim of the project has been to elucidate molecular events leading to amyloidosis in Hereditary Cystatin C Amyloid Angiopathy (HCCAA) patients, to enable simple diagnosis of the disease and with the ultimate goal to understand the amyloid formation process in detail, in order to develop inhibitors to the process. At the DNA level, a point mutation segregating with HCCAA was identified in the cy

Freeze-thaw and de-icing resistance of concrete : research seminar held in Lund, June 17, 1991 : RILEM committee TC-117 FDC

Preface. The RILEM Committee TC-117 FDC -Freeze-Thaw and De-icing Resistance of Concrete:-started its workwith a first meeting that was hel d in Essen in May 1990. A second meeting was held in Brighton in November the same year. During both meetings, some differences in opinion were disc10sed concerning the effects of different externai and internai factors on the de-icing resistance and concernin

Elevated expression of the tumor suppressing protein p53 is associated with the presence of mouse mammary tumor-like env gene sequences (MMTV-like) in human breast cancer

Mouse mammary tumor virus (MMTV) has a proven role in breast carcinogenesis in wild mice and genetically susceptible laboratory inbred mice. The carcinogenic characteristics of this virus are enhanced by estrogen and other steroid hormones. MMTV-like envelope gene sequences, with 95% homology to MMTV have been identified in approximately 40% of breast cancers in US, Australian and Argentinian wome

Electronic and structural properties of GaAs(100)(2x4) and InAs(100)(2x4) surfaces studied by core-level photoemission and scanning tunneling microscopy

Electronic and structural properties of GaAs(100)(2x4), InAs(100)(2x4), and Sb/InAs(100)(2x4) reconstructed surfaces have been studied by synchrotron-radiation photoelectron spectroscopy and scanning tunneling microscopy (STM). Based on the difference spectrum of As 3d core-level spectra of III-As(100)(2x4), measured in different surface-sensitivity conditions, as well as the line shape of the As

Optical and theoretical investigations of small InP quantum dots in GaxIn1-xP

We have studied small InP quantum dots in a GaInP matrix theoretically and experimentally. Using low-temperature photoluminescence spectroscopy in conjunction with six band k.p calculations, including direct and exchange interactions, we show that the dot size is a crucial parameter that determines whether the dot is neutral or charged with electrons in the nominally undoped n-type host material.

Multiblock implementation strategy for a 3-D pressure-based flow and heat transfer solver

This article reports on a multiblock implementation of a general three-dimensional single-block computational fluid dynamics code, which is developed in a nonorthogonal, structured, collocated finite-volume grid system, and incorporates a range of turbulence models. The multiblock implementation is essentially block-unstructured, each block having its own local coordinate system unrelated to those

Synovial fluid concentrations of the C-propeptide of type II collagen correlate with body mass index in primary knee osteoarthritis

OBJECTIVE: To explore in a cross sectional study in patients with primary knee osteoarthritis (OA) the relations between body mass index (BMI), disease stage, and the concentrations of a putative joint fluid marker of type II collagen synthesis, procollagen II C-propeptide.PATIENTS AND METHODS: The study included 142 patients with knee OA (median age 68, median BMI 24.1). OA was staged radiologica

Aktiveringspolitikens Janusansikte : En studie av differentiering, inklusion och marginalisering

Popular Abstract in Swedish Avhandlingen utgår från den förändring som ägt rum i Europa det senaste decenniet, med skiftet från ”welfare” till ”workfare” eller aktiveringspolitik. Vissa forskare hävdar att denna politik är den enda möjligheten till inklusion i arbetsmarknaden, för dem som är exkluderade. Andra hävdar att endast den universella välfärdsstaten kan leda till det resultatet. AvhandlinThe thesis aims to discuss if activation policies can support the inclusion of immigrant women and men into the Swedish labour market.A paradigmatic change in welfare policies has taken place in Europe during the last decade with the shift from welfare to workfare or activation policies. Some researchers claim that, for those excluded from the labour force, activation policies are the only way to

Uniformly accurate quantile bounds via the truncated moment generating function: The symmetric case

Let X-1, X-2,... be independent and symmetric random variables such that S-n = X-1+...+ X-n converges to a finite valued random variable S a. s. and let S* = sup(1 = 94 and y >= 97, respectively. Although our results are derived primarily for symmetric random variables, they apply to non-negative variates and extend to an absolute value of a sum of independent but otherwise arbitrary random variab

Results of two or five years of adjuvant tamoxifen correlated to steroid receptor and S-phase levels

A Swedish cooperative trial demonstrated that 5 years of adjuvant tamoxifen was more beneficial than 2 years of tamoxifen in the treatment of postmenopausal women with estrogen receptor (ER) positive, early stage, invasive breast cancer. The main aim of the present study was to investigate the importance of progesterone receptor (PgR) and ER concentration levels for patients participating in the t

Treatment of phobic postural vertigo A controlled study of cognitive-behavioral therapy and self-controlled desensitization.

In balance clinic practice, phobic postural vertigo is a term used to define a population with dizziness and avoidance behavior often as a consequence of a vestibular disorder. It has been described as the most common form of dizziness in middle aged patients in dizziness units. Anxiety disorders are common among patients with vestibular disorders. Cognitive-behavioral therapy is an effective trea

ADP Acting on P2Y13 Receptors Is a Negative Feedback Pathway for ATP Release From Human Red Blood Cells.

Red blood cells may regulate tissue circulation and O-2 delivery by releasing the vasodilator ATP in response to hypoxia. When released extracellularly, ATP is rapidly degraded to ADP in the circulation by ectonucleotidases. In this study, we show that ADP acting on P2Y(13) receptors on red blood cells serves as a negative feedback pathway for the inhibition of ATP release. mRNA of the ADP recepto

Perchlorate stimulates insulin secretion by shifting the gating of L-type Ca2+ currents in mouse pancreatic B-cells towards negative potentials

The effects of the chaotrophic anion perchlorate (ClO4-) on glucose-induced electrical activity, exocytosis and ion channel activity in mouse pancreatic B-cells were investigated by patch-clamp recordings and capacitance measurements. ClO4- stimulated glucose-induced electrical activity and increased the action potential frequency by 70% whilst not affecting the membrane potential when applied in
