Vesicle formation from temperature jumps in a nonionic surfactant system
When heating a dilute sample of the binary system of tetraethyleneglycol dodecyl ether (C12E4) and water from the micellar phase (L-1) into the two-phase region of a lamellar phase (L-alpha) and excess water (W) vesicles are formed. During heating, one passes a region of phase separation in the micellar phase (L-1' + L-1") where the initial micelles rapidly fuse into larger aggregates forming the
Time-course of liver fat accumulation in man after a single load of ethanol
Three healthy young male subjects were given a single load of ethanol (approximately 3 g/kg body weight) over 5 hours. Liver aspiration biopsies were performed at the start of the experiment and 6, 14, 24, and 48 hours after the start. Blood alcohol and serum transaminase activity levels were measured simultaneously. Triglycerides and phospholipids of the liver biopsy material were determined by a
Mild Microwave-Assisted Hydrolysis of Acetals Under Solvent-Free Conditions
Acetals are efficiently hydrolyzed with silica gel‐supported pyridinium tosylate moistened with water in solvent‐free conditions under microwave irradiation. The method is efficient and mild, with acid‐sensitive 3‐hydroxyacetals and 3‐methoxyacetals being hydrolyzed in minutes in good yields.

Vestibular evoked myogenic potentials in response to skull taps for patients with vestibular neuritis
In recent years it has been demonstrated that loud clicks generate short latency vestibular evoked myogenic potentials (VEMP). It has also been demonstrated that skull tap stimulation evokes similar VEMP. In the present study, the differences between the click-induced and the skull-tap induced VEMP were studied in 18 patients at onset of vestibular neuritis. Gentle skull taps were delivered manual

Determination of pore size distribution by suction porosimetry
Abstract in French La porosimétrie par succion repose sur la mesure de la dépression capillaire que suscite un liquide mouillant retenu dans un milieu poreux. C’est donc une méthode complémentaire à celle de la porosimétrie par pression (par ex. pénétration de mercure) où l’on opère avec des liquides mouillants. On expose la théorie et la pratique des méthodes par succion, entre autres les méthodeThe theory and practice of suction porosimetry methods (suction plate, pressure membrane and centrifuge) are reviewed together with related methods based on the rate of penetration of wetting liquids, and on static and dynamic fluid/fluid displacement measurements.
Anarki och magi
En läsning av Bruno K. Öijers författarskap som ett försök att bekämpa förtryck; detta sker via två vägar eller metoder: anarki och magi. Ytterst är poesin den kraft där dessa vägar sammanstrålar till fullo. Både textanalys och biografiska tolkningar ingår i mitt upplägg.
SIMULTANEOUS COMPARISON OF SEVERAL PRIMARY SEQUENCES AND PREDICTED SECONDARY STRUCTURAL FEATURES
Distributed economies - A new engine for innovation
This article introduces' the concept of distributed economies (DE) as a fresh strategy to guide industrial development towards becoming more sustainable. The concept calls for a transformation in the industrial system towards DE departing from the socio-economically and environmentally unsustainable dynamics associated with large-scale, centralised production units that are favoured by neoclassica
The manifestation of symmetry between the emergence of consciousness and the development of competence
The article presents an experiment in which students, classified according to high and low analytical performance, were given a reading and text production test to determine their sensibility to the structure of an Icelandic saga. This material was used because of its extreme simplicity on the textual surface level, a property suited for studying structure as something beyond the surface. The hypo
Subjective recording of fetal movements. III. Screening of a pregnant population; the clinical significance of decreased fetal movement counts
In order to determine the clinical significance of decreased fetal movement counts, pregnancy outcome was compared between women with decreased fetal movement counts on their Fetal Movement Charts (FMC) (n = 161) and women with normal fetal movement counts (n = 1,354). 1,515 women in the third trimester of pregnancy counted fetal movements for 15 min in the evening and noted the count on a FMC. An
Inhibitory properties of cystatin F and its localization in U937 promonocyte cells
Cystatin F is a recently discovered type II cystatin expressed almost exclusively in immune cells. It is present intracellularly in lysosome-like vesicles, which suggests a potential role in regulating papain-like cathepsins involved in antigen presentation. Therefore, interactions of cystatin F with several of its potential targets, cathepsins F, K, V, S, H, X and C, were studied in vitro. Cystat
Activated cell cycle checkpoints in epirubicin-treated breast cancer cells studied by BrdUrd-flow cytometry
Genetic alterations, such as p53 mutations, may affect a tumour's response to chemotherapy. We have treated two human breast cancer cell lines that differ in p53 status with epirubicin in order to study if there are differences in cell cycle kinetic response. MCF-7 cells express wild-type p53, while SK-BR-3 cells express only a mutated form of p53. The transition of cells from one cell cycle stage

The role of context and inhibition in ADHD.
We have shown in a computational model that a poor memory for context could result in some of the behaviors associated with ADHD, which is well in line with the dynamic developmental theory. Given the important role of context in extinction, a weaker context due to a steeper delay-of-reinforcement gradient would result in impaired inhibition.

Responses to antidromic trigeminal nerve stimulation, substance P, NKA, CGRP and capsaicin in the rat eye
In the rat eye, intracameral injections of substance P in doses of 10-30 pmol caused a maximal long-lasting miosis and a leakage of plasma proteins into the aqueous humor, indicating a breakdown of the blood-aqueous barrier. Neurokinin A seemed equipotent to SP, but calcitonin-gene-related peptide (CGRP) (17 pmol) caused neither miosis nor protein leakage into the aqueous humor. The same result wa
