Vesicle formation in amylose-surfactant mixtures

Images by cryo-transmission electron microscopy show two types of structure in dilute aqueous mixtures of amylose (AM) and sodium dodecyl sulfate (SDS): Loose fibrous networks and unilamellar vesicles. Neither of the structures was observed in reference solutions of AM or SDS alone. It is proposed that both types of structure consist of inclusion complexes where SDS molecules are enclosed in V-typ

Direct care staff's need for support in their perceived work role in day activities units

AIMS: This study sets out to investigate direct care staff's views of their need for support, supervision, and training in their practice in day care settings when supporting daily occupations among developmentally disabled persons. BACKGROUND: The first line staff are considered as having a prominent role in the successful delivery of service. METHODS: Three municipalities, one urban and two rura

Solitons from the Lagrangian perspective

The soliton solution of the Korteweg-de Vries equation provides a good approximation to the shape of a solitary wave solution to the governing equations for water waves. However, the corresponding velocity field below the soliton is not an accurate approximation. We propose an approach that provides us with a better approximation. By describing the particle paths below the free surface, we show th

Hydrology and diatom phytoplankton of high arctic lakes and ponds on Store Koldewey, northeast Greenland

We document hydrological and phytoplankton characteristics of nine lakes and two ponds on Store Koldewey, a culturally undisturbed island off Northeast Greenland. The limnological survey included the recording of temperature, conductivity, oxygen concentration and saturation, pH, ionic composition, transparency, and the diatom phytoplankton community. In summer 2003, the lakes were cold, monomicti

Cerebral function monitoring during the first week of life in extremely small low birthweight (ESLBW) infants

In order to evaluate the usefulness of early continuous EEG-monitoring in very preterm neonates, recordings with a Cerebral Function Monitor (CFM) were made prospectively in 31 ESLBW infants with birthweights below 901 grams, during their first week of life. The CFM background activity was, as expected from EEG studies, dominated by a suppression-burst pattern in 94% of the infants. Some infants h

Genomic characterization of the kidd blood group gene:different molecular basis of the Jk(a-b-) phenotype in Polynesians and Finns

BACKGROUND: The clinically important Kidd (JK) blood group antigens are carried by the urea transporter in red cells. The rare Jk(a-b-) phenotype can be caused by homozygosity at the JK locus for a silent allele, JK: This phenotype has been recorded in many ethnic groups, but it is most abundant among people originating from the Polynesian Islands and Finland. The molecular basis for Jk(a-b-) is u

Disturbances of speech prosody following right hemisphere infarcts

The ability to perceive and express emotional, as well as number of linguistic prosodic qualities of speech was tested in 20 Swedish-speaking patients with right-sided cortical, as well as purely subcortical brain infarcts, and in 18 normal controls. The infarcts were assessed by clinical neurological examination, and by CT, EEG, and measurements of regional cerebral blood flow (rCBF). In the pati

Solvent extraction of hydrofluosilicic acid with alamine 336

Extraction constants for the solvent extraction of hydrofluosilicic acid with Alamine 336 have been determined. Two species were identified, (R3NH+ )2 SiF62- and R3NH+ HSiF6, whose respective extraction constants were determined to be log K21 = 7.42 and log K11 = 2.60. For the dissociation of hydrofluosilicic acid the activity coefficient model presented by Bromley was adapted to sulphuric acid an

Leadership style and managerial type as related to working climate, gender and personality in terms of the Spiral Aftereffect Technique (SAT)

The study considers relations in a group of 95 managers, 41 women and 54 men, between working climate of their units, their leadership styles in terms of their subordinates’ ratings of employee-centeredness, change-centeredness and production-centeredness, and their personality patterns according to the Spiral Aftereffect Technique (SAT). Eight managerial types were distinguished, based on low and

Midline carcinoma with t(15;19) and BRD4-NUT fusion oncogene in a 30-year-old female with response to docetaxel and radiotherapy

Background: Poorly differentiated midline carcinoma with a translocation between chromosomes 15 and 19, i.e. t(15; 19), has been recognized as a distinct clinical entity for over a decade. This tumor affects young individuals, shows a rapidly fatal clinical course despite intensive therapy. The t( 15; 19) results in the fusion oncogene BRD4-NUT. Information concerning treatment of this rare disord

An acoustical technique for determining the loss factor of solid materials

A technique is presented here for evaluating the loss factor of a solid material element. This technique is commonly used in room acoustics to evaluate the reverberation time (RT) of rooms, and is therefore reviewed in this paper for applications in solid materials. The reverberation time is a quantity that describes the rate of decay of the sound level in the room, and is inversely proportional t

Sensitivity in Shear Strength of Longitudinally Reinforced Concrete Beams to Fracture Energy of Concrete

The size effect in shear strength of longitudinally reinforced beams is studied by means of a nonlinear fracture mechanics model. According to the actual theoretical study, structure size should be normalized to an intrinsic length parameter of the concrete. This length parameter is proportional to the fracture energy G//F of the concrete. It is found that the shear strength of a concrete beam may

Isospin breaking in K -> 3 pi decays II: radiative corrections

The five different CP conserving amplitudes for the decays K --> 3pi are calculated using Chiral Perturbation Theory. The calculation is made to next-to-leading order and includes full isospin breaking. The squared amplitudes are compared with the corresponding ones in the isospin limit to estimate the size of the isospin breaking effects. In this paper we add the radiative corrections to the earl

Central role for type I interferons and Tyk2 in lipopolysaccharide-induced endotoxin shock

Toll-like receptor-4 activation by lipopolysaccharide (LPS) induces the expression of interferon-P (IFN-beta) in a MyD88-independent manner. Here we report that mice devoid of the JAK protein tyrosine kinase family member, Tyk2, were resistant to shock induced by high doses of LPS. Basal and LPS-induced expression of IFN-beta and IFN-alpha4 mRNA in Tyk2-null macrophages were diminished. However, T

A Level-set Flamelet Library Model for Premixed Turbulent Combustion

The modelling of premixed turbulent combustion has been studied. Premixed turbulent combustion occurs in a range of applications, such as gas turbines and spark-ignition engines. It is important that the modelling can capture the most relevant details of the combustion in order to minimize the emissions and secure the operability already in the design process of these devices. As the simulation of
