Dependence on oil chain length of the curvature elastic properties of nonionic surfactant films: Emulsification failure and phase equilibria

We compare two ternary microemulsions, stabilized by the nonionic surfactant pentaethylene-glycol-dodecyl-ether (C12E5), containing decane or hexadecane. The comparison involves phase behavior and properties of O/W droplet microemulsions investigated with SAXS, static and dynamic light scattering, and NMR. Striking differences are observed. The systems are analyzed in terms of curvature elastic pr

Cystometric findings in mice lacking muscarinic M2 or M3 receptors

Purpose: The physiological importance of muscarinic M-3 and M-2 receptors for bladder function was investigated in vivo using mice lacking M-3 or M-2 receptors and littermate WT controls. Materials and Methods: Unanesthetized mice of each sex underwent continuous cystometry before and after administration of atropine (1 mg/kg(-1)). Results: Male M-3 knockout (KO) mice had longer voiding intervals,

Are covert verbal responses mediating false implicit memory?

In the DRM paradigm, illusory memories of a nonpresented word can be induced by the presentation of strong associates to this word. In two experiments, we explored previous findings of false implicit memory of the nonpresented words (McDermott, 1997; McKone & Murphy, 2000). Experiment 1 extended the finding of false priming to the anagram task. Furthermore, participants attributed this "false"

Greening Earth? Science, Politics and Land Use in the Kyoto Negotiations

Can a deliberate enhancement of the natural uptake of atmospheric carbon dioxide in forests and agricultural lands contribute to the efforts to mitigation anthropogenic climate change? This is a question that has generated a great deal of debate and controversy since the inception of the multilateral climate negotiations in the early 1990s. This thesis offers an analysis of how this debate has pla

Volatile fatty acid production during anaerobic mesophilic digestion of solid potato waste

The production of volatile fatty acids by anaerobic digestion of solid potato waste was investigated using a batch solid waste reactor with a working capacity of 2 dm(-3) at 37degreesC. Solid potato waste was packed into the digester and the organic content of the waste was released by microbial activity by circulating water over the bed, using batch loads of 500g or 1000 g potato waste. The seque

CMOS On-Chip Clock for Digital Signal Processors

An on-chip clock for frequencies up to 190 MHz is presented. This clock generator can be used for application specific digital signal processors which are clocked faster than the off-chip system clock. It is useful for both processors with a few cycles per sample or for high frequency bit-serial processors which need a large number of cycles

Differential effects of glycoprotein B epitope-specific antibodies on human cytomegalovirus-induced cell–cell fusion

Attachment of, and cell–cell fusion induced by, human cytomegalovirus were studied in the presence of neutralizing monospecific antibodies against antigenic domains 1 (AD-1) or 2 (AD-2) of glycoprotein B (gB, gpUL55). Efficient inhibition of the virion-mediated fusion event was consistently observed for the human AD-2-specific antibody as determined by a reporter gene activation assay based on per

Seger åt Tibet! : den tibetanska diasporan och den religiösa nationen

Popular Abstract in Swedish Tibet och den tibetanska buddhismen har i väst ofta kommit att användas som synonymer. Tidigt kom landets otillgänglighet och stängda dörrar mot omvärlden att utöva en stark lockelse för resande och religiösa sökare. De kom i många fall att betrakta landet och dess folk som bevarare av en kunskap och vishet som gått den övriga världen förlorad. Föreställningen om den rThis dissertation in anthropology of religion focuses on images of Tibet, among Westerners as well as among Tibetans. Based on approximately one year of fieldwork in the former British Hill station, it also deals with the politics of the Central Tibetan Administration (CTA) and some of its political and social implications for the exiled Tibetan youth living in Dharamsala, India. The Western perc

Power mapping and noise reduction for financial correlations

The spectral properties of financial correlation matrices can show features known from completely random matrices. A major reason is noise originating from the finite lengths of the financial time series used to compute the correlation matrix elements. In recent years, various methods have been proposed to reduce this noise, i.e. to clean the correlation matrices. This is of direct practical relev

Kinetic investigation of a PC(sp(3))P pincer palladium (II) complex in the Heck reaction

An investigation of the kinetics of the Heck reaction between 4-iodoanisole and styrene catalysed by {cis-1,3-bis[(di-tert-butylphosphino)methyl]-cyclohexane} palladium (11) iodide (1) has been performed in DMF-d(7) solution. Based on mercury poisoning experiments a heterogeneous palladium catalyst formed from the PCsp3P Pd(II) pre-catalyst is proposed. Saturation behaviour with respect to the ole

An extended probabilistic approach of plant vital attributes: an application to European pollen records at 0 and 6 ka

Aim This paper presents a probabilistic method of pollen spectra analysis. The method relies on a pollen taxon characterization using biotic and abiotic plant attribute modes, and their occurrence in a given pollen spectrum at a specific site. This type of analysis can provide an interpretation, which can lead to the reconstruction of the biome and, to an extent, of the abiotic conditions at the s

Extracting Syringe for determination of organochlorine pesticides in leachate water and soil-water slurry: A novel technology for environmental analysis

The Extracting Syringe (ESy), a novel membrane-based sample preparation technique directly coupled as an autosampler to gas chromatography, has been employed for the analysis of organochlorine pesticides (OCPs) in raw leachate water. The ESy has also been applied for extraction of OCPs from contaminated soil samples and its performance has been compared to liquid-solid extraction (LSE) and acceler

Total C4B deficiency due to gene deletion and gene conversion in a patient with severe infections

Deficiencies of the early components of the classical complement pathway impair the actions of innate and humoral immunity and may lead to increased susceptibility to infections. We have studied the genetic basis of total C4B deficiency in a Finnish patient with recurrent meningitis, chronic fistulas and abscesses. The maternal chromosome carried a four-gene deletion including the C4B gene, and a
