We report on the first time-resolved small-angle neutron scattering (SANS) study of the structural relaxation from a shear-induced aligned state back to the isotropic state in a system of giant wormlike reverse micelles. The micelles are formed by lecithin and small amounts of water in cyclohexane. A liquid sample with the micellar volume fraction phi = 0.3 was exposed to a steady shear of (gamma)
Stimulation of endogenous kinin receptors promotes growth of androgen-independent prostate cancer PC3 cells via activation of the mitogenic extracellular-signal-regulated kinase (ERK) pathway. In the present study, we show that kinin-mediated mitogenic signalling and prostate-cell growth involves two subtypes of bradykinin (BK) receptors, B1R and B2R. Specific stimulation of either B1R or B2R by t
As most adults will marry at least once during their lifetime, studying marital quality and its predictors is of great importance. The current study addresses (a) the extent of agreement between husbands and wives on their marital quality, (b) genetic and environmental sources of individual differences on spouse reports of marital quality, and (c) the extent to which genetic and environmental infl
Two new alpha-pyrone derivatives, xylarone (1) and 8,9-dehydroxylarone (2) possessing cytotoxic activities, were isolated from the culture fluid of submerged cultures of the ascomycete Xylaria hypoxylon, strain A27-94. Their structures were elucidated by spectroscopic methods.
I present the status of the T(HE)PEG project for creating a common platform for implementing C++ event generators. I also describe briefly the status of the new versions of P-YTHIA, (HERWIG) and A(RIADNE) which are implemented using this framework. (c) 2005 Elsevier B.V. All rights reserved.
Popular Abstract in Swedish Denna avhandling behandlar metoder för att modellera risk på de finansiella marknaderna. Avhandlingen består av fyra separata uppsatser och inleds med en introduktion i kapitel ett, medan kapitel två till kapitel 5 består av de fyra uppsatserna. Den första uppsatsen undersöker implikationerna av att använda olika riskmått inom portföljval. Speciellt undersöks tre olikaThis thesis deals with techniques to model risk in financial markets and consists of four separate essays. The thesis begins with an introduction in chapter one, while chapter two to chapter five contains the four essays. The first essay examines the implication of using various risk measures for portfolio selection. Specifically, three risk measures are examined: variance, Value at Risk (VaR) an
Objectives To determine which endometrial morphology characteristics as assessed by gray-scale ultrasound and which endometrial vessel characteristics as assessed by power Doppler ultrasound are useful for discriminating between benign and malignant endometrium in women with postmenopausal bleeding (PMB) and sonographic endometrial thickness > 4.5 mm and to develop logistic regression models to ca
Objective: To evaluate aspects of internal scale validity and reliability of the Swedish version of the Impact on Participation and Autonomy questionnaire (IPA-S) for use in people with spinal cord injury. Subjects: A total of 161 persons with spinal cord injury. Method. IPA-S psychometric properties were evaluated using Rasch rating scale analysis. Results: The results show that the IPA-S has 27
The mammalian achaete-scute homologue, MASH-1, is crucial for early development of the sympathetic nervous system and is transiently expressed in sympathetic neuroblasts during embryogenesis. Here we report that the human homologue (HASH-1) was expressed in all analyzed cell lines (6/6) derived from the sympathetic nervous system tumor neuroblastoma. The majority of small-cell lung carcinoma (4/5)
Early hypocalcemia after thyroid surgery has frequently been reported, whereas data regarding long-term effects on calcium homeostasis are scarce. We have previously studied patients after hemithyroidectomy with an oral calcium load test and found normal parathyroid hormone (PTH) suppression. However, the 1,25-dihydroxyvitamin D concentration was decreased and the phosphate concentration increased
The Gammasphere spectrometer, in conjunction with the Microball charged-particle array, was used to investigate high-spin states in Te-112 via Ni-58(Ni-58, 4p gamma) reactions at 240 and 250 MeV. Several smooth terminating bands were established, and lifetime measurements were performed for the strongest one using the Doppler-shift attenuation method. Results obtained in the spin range 18-32h yiel
Sedimentological, pedological and palynological evidence reveal radically increasing onshore humidity during the Rhaetian marine invasion of central Europe along the north-eastern margin of the Central European Basin (southern Sweden). Pre-Rhaetian aridity favoured the formation of Carnian redbeds with calcrete, which were succeeded by Norian hematite-cemented conglomerates, arkoses, arkosic wacke
I artikeln framhålls att den internationellt mycket höga fackliga organisationsgraden i Sverige beror på flera faktorer: förekomsten av fackliga a-kassor och fackliga konfliktfonder, att den svenska fackföreningsrörelsen på en och samma gång är mer centraliserad och decentraliserad än i många andra länder samt frånvaron av splittring längs politiska eller religiösa skiljelinjer. Därtill kommer att
