Time-dependent surface speciation of oxalate at the water-boehmite (gamma-AlOOH) interface: Implications for dissolution

The surface speciation Of Oxalate at the water-boehmite (gamma -AlOOH) interface during adsorption and dissolution reaction,; wa,; studied by means of attenuated total reflectance infrared spectroscopy. The structural interpretations of infrared (IR) data were based on comparison with results from theoretical frequency calculations. Two different surface complexes were identified: an inner-sphere

Steady-State and Dynamic Assessment of Forest Soil Acidification in Switzerland.

The European steady-state Simple Mass Balance (SMB) model and the dynamic soil acidification model SAFE were used to assess the risk of future forest soil acidification in Switzerland. 2010 deposition forecasts on a 150x150 km grid resolution as well as corresponding ecosystem protection levels were obtained from RAINS model runs based on the 1999 Gothenburg Protocol obligations under the UN/ECE L

Pelvic floor muscle training is effective in women with urinary incontinence after stroke: A randomised, controlled and blinded study

Aims: The aim of this study was to evaluate the effect of Pelvic Floor Muscle Training (PFMT) in women with urinary incontinence (UI) after ischemic stroke. Materials and Methods: Three hundred and thirty-nine medical records of stroke patients were searched. Twenty-six subjects were randomised to a Treatment Group (14 subjects) or a Control Group (12 subjects) in a single blinded, randomised stud

Investments in social capital - implications of social interactions for the production of health

This paper develops a theoretical model of the family as producer of health- and social capital. There are both direct and indirect returns on the production and accumulation of health- and social capital. Direct returns (the consumption motives) result since health and social capital both enhance individual welfare per se. Indirect returns (the investment motives) result since health capital incr

A 1 : 1 complex between a hydroxyl radical and ozone

A hydrogen bonded complex between a hydroxyl radical and ozone has been found in argon matrices at 9 K. The shift of the OH stretch (-12.6 cm(-1)) indicates that this complex is somewhat weaker than the OH-CO complex (-21.8 cm(-1), D-0

Ethnic identity, power, and communication in top management teams

Purpose - The purpose of this paper is to explore the "black box" of top management team (TMT) processes such as communication and power distribution, examining the example of ethnically diverse TMTs in Latvia. Design/methodology/approach - The study relies on case studies of two multinational companies operating in Latvia. Findings - The findings suggest that ethnic diversity in TMTs leads to mor

Globalization and Religious Nationalism: Self, Identity and the Search for Ontological Security

The globalization of economics, politics, and human affairs has made individuals and groups more ontologically insecure and existentially uncertain. One main response to such insecurity is to seek reaffirmation of one's self identity by drawing closer to any collective that is perceived as being able to reduce insecurity and existential anxiety. The combination of religion and nationalism is a par

Streptococcal M protein: Structural studies of the hypervariable region, free and bound to human C4BP

Streptococcus pyogenes is a Gram-positive bacterium that causes several diseases, including acute tonsillitis and toxic shock syndrome. The surface-localized M protein, which is the most extensively studied virulence factor of S. pyogenes, has an similar to 50-residue N-terminal hypervariable region (HVR) that plays a key role in the escape of the host immunity. Despite the extensive sequence vari

Nanoplasmonic biosensing with focus on short-range ordered nanoholes in thin metal films

The resonance conditions for excitation of propagating surface plasmons at planar metal/dielectric interfaces and localized surface plasmons associated with metal nanostructures are both sensitive to changes in the interfacial refractive index. This has made these phenomena increasingly popular as transducer principles in label-free sensing of biomolecular recognition reactions. In this article, t

Histopathological risk factors for ipsilateral breast events after breast conserving treatment for ductal carcinoma in situ of the breast - Results from the Swedish randomised trial.

Aim: The primary aims were to study risk factors for an ipsilateral breast event (IBE) after sector resection for ductal carcinoma in situ of the breast (DCIS) in a trial comparing adjuvant radiotherapy to no therapy and to assess predictive factors for response to radiotherapy Secondary aims were to analyse reproducibility of the histopathological evaluation and to estimate correctness of diagnos

Swedish moist snuff accelerates gastric cancer development in Helicobacter pylori-infected wild-type and gastrin transgenic mice

The Swedish variant of moist oral smokeless tobacco (snus) is popular in Sweden and Norway, banned from sale within the European Union and is currently being introduced in USA. The aim of the present study was to determine if snus is carcinogenic to the stomach, particularly in Helicobacter pylori (H.P.)-infected hosts at increased risk for gastric cancer development. Snus (General (TM); Swedish M

The effect of increased apparatus dead space and tidal volumes on carbon dioxide elimination and oxygen saturations in a low-flow anesthesia system.

STUDY OBJECTIVE: To determine if a large tidal volume (V(T)), with an unchanged end-tidal carbon dioxide partial pressure (P(ET)co(2)), could improve arterial carbon dioxide elimination, oxygen saturation (Spo(2)), and arterial blood oxygenation. DESIGN: Prospective, randomized, clinical study. SETTING: Single university hospital. PATIENTS: 60 ASA physical status I and II patients scheduled for el

Persistent itching nodules after the fourth dose of diphtheria-tetanus toxoid vaccines without evidence of delayed hypersensitivity to aluminium

Studies in Gothenburg, Sweden, reported an exceptionally high rate of persistent itching nodules at the site of injection of aluminium containing vaccines, usually with positive epicutaneous tests to aluminium. When a new booster diphtheria-tetanus vaccine was introduced we performed a prospective cluster randomised active surveillance in 25,232 10-year-olds. Parental reports 6 months after vaccin

Adaptation of soil microbial communities to temperature: comparison of fungi and bacteria in a laboratory experiment

Temperature not only has direct effects on microbial activity, but can also affect activity indirectly by changing the temperature dependency of the community. This would result in communities performing better over time in response to increased temperatures. We have for the first time studied the effect of soil temperature (5-50 degrees C) on the community adaptation of both bacterial (leucine in

An increased micronucleus frequency in peripheral blood lymphocytes predicts the risk of cancer in humans

The frequency of micronuclei (MN) in peripheral blood lymphocytes (PBL) is extensively used as a biomarker of chromosomal damage and genome stability in human populations. Much theoretical evidence has been accumulated supporting the causal role of MN induction in cancer development, although prospective cohort studies are needed to validate MN as a cancer risk biomarker. A total of 6718 subjects

Thermodynamic format and heat generation of isotropic hardening plasticity

Heat generation due to plastic deformation of metals and steel is studied. Whereas in many investigations it is assumed that the fraction eta of the plastic work transformed into heat is constant throughout the deformation process, the fraction eta is here derived from thermodynamic considerations in a large-strain setting. It is shown that for elasto-plasticity the fraction eta follows as a resul

A new type of long gamma-ray burst

We consider gamma-ray bursts (GRBs) produced by the merger of a massive white dwarf with a neutron star. We show that these are likely to produce long-duration GRBs, in some cases definitely without an accompanying supernova, as observed recently. This class of burst would have a strong correlation with star formation, and occur close to the host galaxy. However, rare members of the class need not
