Dual-broadband rotational CARS (DB-RCARS) thermometry has been investigated at high temperature and high pressure. Single-shot measurements were performed at 1800 K, in air and nitrogen at pressures up to 1.55 MPa and in oxygen at pressures up to 0.5 MPa. For all conditions, the resonant signal contribution to the spectra clearly dominated over the non-resonant one, implying the high potential for

Popular Abstract in Swedish I de flesta organ i människokroppen pågår en ständig förnyelse av celler för att kompensera för gamla cellers bortfall som en följd av skador och naturlig död. En ensam cell kan på egen hand kopiera allt sitt DNA och därmed all information den bär på, för att därefter dela sig och skapa en exakt identisk kopia av sig själv. Kodat i DNA finns instruktionerna för hur en oTelomeres are the end-structures of linear chromosome which are crucial for maintaining genome integrity. The telomeres prevent the DNA-repair machinery from recognizing the chromosome ends as double-strand breaks and from end-to-end fusions. The telomeres are composed by short repetitive units of TG-rich DNA and associated specialized telomere-binding proteins. Due to that replication only can

Nanowires in the InAs/InP material system are grown with catalyst-assisted chemical beam epitaxy. Ohmic contacts are then fabricated to selected wires, allowing electron transport measurements to be carried out at room-temperature as well as at low T. InAs nanowires show strong quantum confinement effects, where thin wires (<30nm) are depleted from carriers. Measurements on InAs wires with a quant

PEG self-diffusion coefficients of poly(ethylene glycol)s (PEGs) (1080, 8500, and 82 250 g/mol) were measured by PFG-NMR spectroscopy in whey protein solutions and gels in relation to whey protein concentration effects (from 6.49 to 40.45 g/100 g) and whey protein heat denaturation effects (30 min at 70 degrees C). A strong dependency of diffusion on probe size was observed in both whey protein so

Proton motions in hydrated proton conducting perovskites BaZr(0.90)A(0.10)O(2.95) (A = Y and Sc) have been investigated using quasielastic neutron scattering. The results reveal a localized motion on the ps time scale and with an activation energy of similar to 10-30 meV, in both materials. The temperature dependence of the total mean square displacement of the protons shows an onset of this motio

Infection with Trypanosoma cruzi causes megasyndromes of the gastrointestinal (GI) tract. We used magnetic resonance imaging (MRI) to monitor alterations in the GI tract of T. cruzi-infected mice, and to assess the role of nitric oxide (NO) in the development of intestinal dilation. Brazil strain-infected C57BL/6 wild-type (WT) mice exhibited dilatation of the intestines by 30 days post-infection.

Two genetically modified potato starches derived from the same mother line (64%, 1% and 23% amylose, respectively) were used to study the bioavailability after various heat treatments. The conditions for the treatments were of minor importance for resistant starch (RS) formation and hydrolysis results, as compared to the proportion of amylose. A high amylose content gave lower hydrolysis index (HI

Here we report on the development of a proteomic platform utilizing a piezoelectric flow-through dispensing unit made from silicon microstructures. The use of a novel surface coating, where matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI MS) targets were uniformly precoated with a thin film of matrix/nitrocellulose, made the sample preparation straightforward an

We wanted to test whether living environment, occupation and social position are risk factors for asthma and chronic bronchitis/emphysema (CBE). The prevalence of bronchial asthma, CBE, respiratory symptoms and smoking habits in a random sample of 12,071 adults aged 20-59 years was assessed in a postal survey with a slightly modified questionnaire previously used in central and northern Sweden (Th

A new method for rapid determination of oxalic acid was developed using oxalate oxidase and a biosensor based on SIRE (sensors based on injection of the recognition element) technology. The method was selective, simple, fast, and cheap compared with other present detection systems for oxalate. The total analysis time for each assay was 2-9 min. A linear range was observed between 0 and 5 mM when t

This paper presents a test of modelling of fungal growth based on the heat produced by Penicillium roqueforti growing on malt extract agar. Thermal power (heat production rate) of P. roqueforti was measured by isothermal calorimetry at 10, 15, 20, 25 and 30°C. The equivalent diameter of similar colonies growing at 20°C were measured by image analysis. Four predictive equations including time lag w

A two-stage procedure for pretreatment of fast-growing willow with steam has been investigated. The first stage was performed at temperatures in the range 180°C to 220°C for times between 6 and 10 minutes while the second stage was performed at 220°C for 10 minutes. The fibrous material was washed between the two stages to remove the pentosans and thus increase the pentose yield. The pretreatment

CONCLUSION: Subjects with self-reported nasal symptoms following consumption of red wine may respond with less nasal blockage to a wine produced with ecological methods than to wine not labelled as ecologically produced. OBJECTIVE: To compare nasal symptoms following intake of three different wines--one that was ecologically produced and two that were traditionally produced. SUBJECTS AND METHODS:

The purpose of this study was to investigate the early alterations of retinal function, assessed with electrophysiology, in newly onset type 2 diabetes patients without vascular retinopathy. Seventeen patients with newly diagnosed type 2 diabetes (duration 7 ± 3 months), without any vascular retinopathy in fundus photographs, were examined with full-field electroretinogram (ERG) and multifocal ERG

Insectivore classification has been one of the most controversial problems in mammalian systematics. Evolutionary relationships among the six extant families, Talpidae (moles), Soricidae (shrews), Erinaceidae (hedgehogs), Tenrecidae (tenrecs), Chryosochloridae (golden moles), and Solenodontidae (solenodons), have remained uncertain based on morphological data. Animals classified within the order L

This investigation takes its point of departure in the prominent use of the term ’musicality’ as a prestige word in theatre discourse where, obviously, not exactly the same reference and meaning is ascribed to the concept as in contexts of music. There seems to be very little previous research in this area, if any. The research question is formulated thus: What do theatre practicians mean when the

The object of this study was to determine the association between tender point pain ratings, tender point counts and distress in people with fibromyalgia and to review the pharmacotherapy of fibromyalgia. Demographic, psychosocial, and health status information was collected from 316 health maintenance organization members with fibromyalgia. A manual tender point exam was conducted. Tender point c

Global exploration and production of minerals is increasingly located in areas populated by indigenous people. Conflicts that arise between multinational corporations and local activists and/or indigenous people are widespread while the understanding of such issues are still lacking. The Swedish government encouraging an expanding mining industry have caused great resistance, particularly due to t
