Dependence of Curie temperature on the thickness of epitaxial (Ga,Mn)As film
We present the magnetotransport properties of very thin (5-15 nm) single (Ga,Mn)As layers grown by low-temperature molecular beam epitaxy. A lower (Ga,Mn)As thickness limit of 5 nm for the ferromagnetic phase and the dependence of the Curie temperature on (Ga,Mn)As thickness are determined from electrical-transport measurements. The Curie temperature is determined to be 97 K for the thinnest ferro
A method to simultaneously determine sorption isotherms and sorption enthalpies with a double twin microcalorimeter
Sorption of vapors of water, ethanol, and other liquids on solids like pharmaceuticals, textiles and food stuffs are of both practical and theoretical importance. In this article we present a technique to simultaneously measure sorption isotherms and sorption enthalpies. The sample is contained in one end of a sorption vessel. In the other end a vaporizable liquid is introduced to start the measur
Hydrogenation of Benzene to Cyclohexene on an Unsupported Ruthenium Catalyst: Effects of Poisons
The influence of poisoning of ruthenium catalysing the selective hydrogenation of benzene to cyclohexene has been studied. Both the yield of cyclohexene and the rate of hydrogenation are greatly affected by the degree of poisoning (e.g. FeSO4, FeCl3, TiCl3 and oxygen), and may also be optimised. A reproducible catalyst has been prepared by precipitating the catalyst precursor, as the hydroxide, in
Test-retest reliability of knee kinesthesia in healthy adults
Background Sensory information from mechanoreceptors in the skin, muscles, tendons, and joint structures plays an important role in joint stability. A joint injury can lead to disruption of the sensory system, which can be measured by proprioceptive acuity. When evaluating proprioception, assessment tools need to be reliable. The aim of this study was to assess the test-retest reliability of a de
Prevalence and clinical correlations of antibodies against six beta 2-glycoprotein-I-related peptides in the antiphospholipid syndrome
Two-hundred ninety five patients with the antiphospholipid syndrome (APS) were studied for the presence of antibodies against six anti-beta2GPI-related peptides Abs. The prevalence of a wide spectrum of clinical and laboratory parameters of APS was evaluated in all patients, and correlated with the presence of each anti-beta2GPI peptide antibody. The rates of the various antipeptides Abs ranged fr
Some novel aspects of DNA physical and chemical gels
DNA chemical and physical networks have been investigated with respect to their stability and swelling, and rheological properties. Chemical networks were prepared by cross-linking DNA with ethylene glycol diglycidyl ether (EGDE), and physical networks by association with cationic polymers. Both types of gels display strong elastic properties and have a shear thinning behaviour. Addition of cation

Use of anti-asthmatic drugs during pregnancy. 1. Maternal characteristics, pregnancy and delivery complications.
Objective To study, in a large cohort, the association between the use of anti-asthmatic drugs during pregnancy and pregnancy complications. Methods Using the Swedish Medical Birth Register, we identified 24,369 women who reported the use of anti-asthmatic drugs in early pregnancy and 7778 women who were prescribed such drugs later during pregnancy by antenatal care system centres, during the peri
Hydrophobicity and counterion effects on the binding of ionic surfactants to uncharged polymeric hydrogels
Gel swelling experiments have been used to study the binding of ionic surfactants to a series of nonionic alkylacrylamide hydrogels of increasing hydrophobicity. The binding of hexadecyl trimethylammonium (C-16-TA(+)) to uncharged gels is sensitive to both the hydrophobicity of the gel and the counterion to the surfactant. There is a minimum hydrophobicity threshold below which binding of the surf

Mellan människor och ting : En interaktionistisk analys av samlandet
Popular Abstract in Swedish Inom de flesta sociologiska forskningsperspektiv tillskrivs mellanmänsklig interaktion avgörande betydelse för att förstå olika aspekter av det sociala livet. I denna studie ligger emellertid fokus på den praktiska och erfarenhetsmässiga relationen mellan människor och ting ? en relation med stor betydelse för individers identitet och sociala liv. Detta är ett ofta bortIn most sociological paradigms the importance of human interaction for the understanding of societies, is a well established fact. In this study, the focus is the interaction between human beings and material things as it is occurring in practice. Such an approach with its important consequences for understanding both social life and self, is often overlooked in studies within the field of sociolo
Recovery of cognitive and emotional functioning following withdrawal of topiramate maintenance therapy
The present investigation reports cognitive improvement following withdrawal of topiramate (TPM) maintenance therapy in two patients with intractable seizures. The first patient received a neuropsychological evaluation after 10 months of adjunctive TPM treatment and was reassessed after complete withdrawal. The second patient received a first evaluation without TPM therapy. A reassessment was cond

Identification of emission lines in the low-ionization strontium filament near Eta Carinae
Spectral lines observed in the Sr-filament of eta Car in the wavelengthregion 2480-10140{AA}. The lines are sorted by wavelength in table 2 andsorted according to the periodic table in table 3. Both tables areavailable in postscript format as the file tables23.ps where the sub andsuperscripts for the atomic transitions are kept.(2 data files).

Mortality among elderly receiving long-term care: a longitudinal cohort study.
Backgrounds and aims: To investigate mortality, determinants of mortality, and time until death among elderly subjects receiving public long-term care. Methods: This study comprises 626 respondents (age: 65-98 years). Data were collected for two cohorts (2001 and 2002). Cox regression analysis was used to identify determinants of mortality. Those who died and those who did not die were compared by
