In the present work we show the capabilities of the new protocol called cryo-fracture TEM recently developed in our laboratory. The systems selected to test the protocol were C12E8-water and P84-water, and the phases imaged were lamellar (L-alpha), hexagonal (H-1) and cubic (I-1). This protocol is a natural extension of the capabilities of conventional cryo-TEM, which enables direct imaging of vis
We consider the problem of describing the correlation between two compositions. Using a bicompositional Dirichlet distribution, we calculate a joint correlation coefficient, based on the concept of information gain, between two compositions. Numerical values of the joint correlation coefficient are calculated for compositions of two and three components. We also present an estimator of the joint c
This paper is part of a broader multilingual research project that addresses the relationships between affective phenomena (as units of personal experience), concepts (as units of cognitive processing) and the lexical items we use in talking about affective experience (as units of verbal communication. The focus will be here on data obtained in six Scandinavian and Romance languages (N=1093) with
Bicontinuous and water-in-diesel microemulsions were formulated using single nonionic alkyl poly glycol ethers combined with hydrophilic alcohol ethoxylates. The phase behavior at temperatures ranging from 0 degrees C to 50 degrees C was investigated. Visual inspection as well as cross-polarizers were used to detect anisotropy. The fish phase diagrams were determined. The presence of the hydrophil
This paper discusses current Swedish international development policies on gender and violence. It deals with the relationship between development policies, global health, promotion of gender equality, and violence against women in a global perspective. The focus is on intimate partner violence and the highly promoted gender mainstreaming policy. Theoretically, our point of departure lies within a
BACKGROUND AND PURPOSE: Following transtibial amputation, a rigid dressing of plaster of Paris has been reported to have advantages over a soft dressing regarding wound healing and reduction of edema, but use of the former may be limited by difficulties in application and in gaining access to the wound. An easily applicable and removable vacuum-formed rigid dressing (ORD) has recently been introdu
This contribution concerns the development of generic methods and tools for robust optimal control of high-pressure liquid chromatographic separation processes. The proposed methodology exploits a deterministic robust formulation, that employs a linearization of the uncertainty set, based on Lyapunov differential equations to generate optimal elution trajectories in the presence of uncertainty. Co
The specific insertion of a divalent metal ion into tetrapyrrole macrocycles is catalyzed by a group of enzymes called chelatases. Distortion of the tetrapyrrole has been proposed to be an important component of the mechanism of metallation. We present the structures of two different inhibitor complexes: (1) N-methylmesoporphyrin (N-MeMP) with the His183Ala variant of Bacillus subtilis ferrochelat
Ulf Arup fortsätter det mödosamma arbetet med att revidera det artrika släktet orangelavar, Caloplaca. I ett nyligen publicerat arbete i Lichenologist presenterade Ulf resultaten av en genetisk och morfologisk undersökning av C. holocarpa-gruppen och liknande arter i Norden (Arup 2009). Nedan ges en sammanfattande redogörelse för de resultaten.
Above its critical aggregation concentration the tfa salt of the peptide A(6)K self-assembles into micron long, hollow nanotubes with uniform diameters of 52 nm and crystalline order. Here we combine the use of SAXS with cryoTEM and cryo-electron tomography (cryoET, 3D cryoTEM) to study the formation process of the 2D crystalline A(6)K nanotubes. This study reveals that the formation of these tube
Background: Plasma phospholipid fatty acids have been correlated with food intakes in populations with homogeneous dietary patterns. However, few data are available on populations with heterogeneous dietary patterns. Objective: The objective was to investigate whether plasma phospholipid fatty acids are suitable biomarkers of dietary intakes across populations involved in a large European multicen
This paper investigates an allocation rule that fairly assigns at most one indivisible object and a monetary compensation to each agent, Under the restriction that the monetary compensations do not exceed some exogenously given upper bound. A few properties of this allocation rule are stated and the main result demonstrates that the allocation rule is coalitionally strategy-proof. (C) 2008 Elsevie
Objective. The prevalence of anemia in inflammatory bowel disease (IBD) has been broadly described. The recurrence, type and burden of anemia remain unenlightened. The primary objective was to describe this. The secondary objective was to evaluate the implementation of European guidelines. Materials and methods. This longitudinal follow-up study included 300 IBD outpatients from six centers in Sca
The importance of proper mutational analysis of BRCA1/2 in individuals at risk for hereditary breast and ovarian cancer syndrome is widely accepted. Standard genetic screening includes targeted analysis of recurrent, population-specific mutations. The purpose of the study was to establish the frequency of germline BRCA1/2 mutations in a group of 134 unrelated patients with primary ovarian cancer.
Decays of neutron-rich A similar to 190 nuclei have been studied following projectile fragmentation of a Pb-208 beam on a Be-9 target at the GSI Fragment Separator. Gamma-ray decays from previously reported isomeric states in Ta-188, W-190 and (192,193) Re were used as internal calibrations for the particle identification analysis, together with the identification of previously unreported isomeric
