Vowel harmony shift in Mongolian

It has generally been assumed that Mongolian has vowel harmony of the palatal (front-back) type, but in this article I will present acoustic data from several Mongolian dialects, which show that there has been a shift in the phonetic basis of vowel harmony from palatality in Classical Mongolian to pharyngeality in modern East Mongolian (including Khalkha and Inner Mongolian). I will also treat Mo

Characterization of a glutamate biosensor based on a novel glutamate oxidase integrated into a redox hydrogel

A newly isolated and purified glutamate oxidase was used to construct amperometric biosensors for glutamate monitoring. The enzyme-producing microorganism belongs to the genus of Streptomyces - Streptomyces sp. Z-11-6 - and is capable of producing extracellular L-glutamate oxidase. The microorganism was obtained by mutagenesis with HNo2 from a parent strain isolated from soil of Lypetskaya region,

DNA-based classification and sequence heterogeneities in the 16S rRNA genes of Lactobacillus casei/paracasei and related species.

The sequence differences within the 16S rRNA genes of Lactobacillus casei/paracasei and related species, Lactobacillus zeae and Lactobacillus rhamnosus, were investigated. Thirty-seven strains of mostly human or cheese origin were grouped by restriction endonuclease analysis (REA) of the total chromosomal DNA and by temporal temperature gradient gel electrophoresis (TTGE) of PCR-amplified 16S rRNA

Relation between reduction of foveal thickness and visual acuity in diabetic macular edema treated with intravitreal triamcinolone

PURPOSE: To evaluate the correlation between improvement in visual acuity and the reduction of foveal thickness after a single intravitreal injection of 4 mg of triamcinolone in diabetic macular edema. DESIGN: Prospective, interventional, nonrandomized clinical trial. METHOD: PATIENTS: In a prospective study 24 eyes with diabetic macular edema were treated with an intravitreal injection of 4 mg of

Molecular Characterization of the Interaction between Porins of Neisseria gonorrhoeae and C4b-Binding Protein.

Neisseria gonorrhoeae, the causative agent of gonorrhea, is a natural infection only in humans. The resistance of N. gonorrhoeae to normal human serum killing correlates with porin (Por)-mediated binding to the complement inhibitors C4b-binding protein (CUP). The entire binding site for both porin molecules resides within complement control protein domain 1 (CCPI) of C4BP. Only human and chimpanze

A Novel Signal Model and Estimation Method for Acoustic Doppler Current Meters

Popular Abstract in Swedish Denna avhandling behandlar den process där man beräknar undervattensströmmar från ljud som reflekteras från en utsänd ljudpuls, precis som när en fladdermus bedömer omgivningen genom att lyssna på ekot. En ton skickas ut under en kort tid, och det Dopplerskift som uppkommer från rörliga föremål i vattnet kan sedan omsättas till vattenhastiget eller ström. Föremål som röThis thesis deals with the process of estimating underwater current from the backscattering signal transmitted from an ultrasonic transducer. The narrowband sinusoidal burst signal is Doppler-shifted due to the current, and this information is converted into current. The traditional mathematical model for this Doppler process is based on the assumption that the backscattering time signal is Gaussi

Harvesting-induced population fluctuations?

It has recently been shown that damped endogenous dynamics is a common feature in Finnish grouse species; In this paper, we demonstrate that time-variant harvesting may turn damped dynamics to quasi-periodic fluctuations. Exploited populations, e.g. grouse, may therefore fluctuate more than expected if we do not manage to keep the harvest fraction constant over time. However, the harvest fraction

Clinical experience with a customized fenestrated endograft for juxtarenal abdominal aortic aneurysm repair

Despite the numerous stent-graft devices available, unsuitable anatomy is still the greatest exclusion criterion for endovascular abdominal aortic aneurysm (AAA) repair (EVAR). The present report describes an on-site preprocedural customization of a conventional Zenith stent-graft device just before the endovascular procedure that includes the creation of fenestrations and scallops as necessary fo

Baseline verbal fluency performance as predictor of state anxiety during a live hand-grenade throwing exercise - A prospective study of Swedish military conscripts

Background: We investigated whether individual differences in baseline executive control capacity could predict state anxiety during a potentially life-threatening situation. Methods: 19 Swedish military conscripts were assessed during two measurement occasions. During a baseline measurement, data regarding performance on a letter fluency task and state anxiety were assessed. During a second measu

Nosocomial transmission of Legionella pneumophila to a child from a hospital's cold-water supply.

Human Legionella infections mainly consist of community-acquired and nosocomial pneumonia and rarely affect children. We describe a nosocomial infection with Legionella pneumophila, serogroup 1, subgroup OLDA, in an immunocompromized 2-y-old girl at a paediatric clinic. L. pneumophila identical to that of the patient was found in the hospital's cold-water but not in the hot-water distribution syst
