Spectroscopic measurements of streamer filaments in electric breakdown in a dielectric liquid

Emission spectroscopy has been utilized to provide information about the electron density and temperature in streamers and breakdown arcs in transformer oil. Recorded spectra include strongly broadened hydrogen Balmer-alpha lines and vibration/rotation band profiles of the C-2 molecule. The origin of the observed broadening of hydrogen lines is discussed and it is concluded that it arises mainly f

Analysis of gas dispersed in scattering media

Monitoring of free gas embedded in scattering media, such as wood, fruits, and synthetic materials, is demonstrated by use of diode laser spectroscopy combined with sensitive modulation techniques. Gas detection is made possible by the contrast of the narrow absorptive feature of the free-gas molecules with the slow wavelength dependence of the absorption and scattering cross sections in solids an

On Bubble Dynamics in Acoustic Cavitation

Nyligen har mycket uppmärksamhet ägnats åt studier rörande ickelinjära oscillationer av sfäriska gasbubblor i pulserande tryckfält. Denna lic-avhandlning syftar till att utöka kunskapen kring kavitationsfenomenet. I detta arbete undersöks olika modeller och en förbättrad numerisk modell har utvecklats för att analysera akustiska kavitationsfenomen. Resultaten från den utvecklade modellen innefatta

Relationships between occupational engagement and status of and satisfaction with sociodemographic factors in a group of people with schizophrenia.

Abstract The present study is part of a larger project investigating occupational engagement and health in a group of people with schizophrenia. This study was aimed at extending this knowledge base with regard to occupational engagement and sociodemographic factors. Seventy-four outpatients participated in the study. The Profile of Occupational Engagement in People with Schizophrenia, the Lancash

Resource interfaces telling other stories about the commercial use of new technology: The embedding of biotech solutions in US, China and Taiwan

This study focuses on the embedding of new biotech solutions into three business landscapes - US, China and Taiwan. A "state-of-the-art" chromatography system tuned for operating in the step between laboratory and large-scale production is used as the common point of departure to investigate the supplier-user interfaces involving biotechnology in each of the three countries; the resource interacti

Transient Receptor Potential A1 (TRPA1) Activity in the Human Urethra-Evidence for a Functional Role for TRPA1 in the Outflow Region.

BACKGROUND: A role for the transient receptor potential (TRP) A1 ion channel in rat lower urinary tract (LUT) sensation and disease has been proposed, but in the human LUT no information on TRPA1 activity is available. OBJECTIVES: To investigate the distribution of TRPA1 in the human urethra and to study the effect of TRPA1 agonists on isolated urethral strip preparations. DESIGN, SETTINGS, AND PA

Nothing more to see : Contestations of belonging and visibility in Russian media

Popular Abstract in Swedish Syftet med denna avhandling är att undersöka vilken roll synlighet spelar i skapandet och utmanandet av tillhörighet till politiska gemenskaper. Baserat på en empirisk studie av ryska medier under 2010-talet föreslås ett sätt att teoretiskt begreppsliggöra förhållandet mellan synlighet och tillhörighet, som utgår från idén att vad som blir synligt för en publik och hur,The purpose of this dissertation is to explore the role of visibility in the production and contestation of belonging to political communities. On the basis of an empirical enquiry of Russian media during the 2010s, a theoretical conceptualization of the relation between visibility and belonging is suggested, starting in the idea that what becomes visible to publics and how, and what is rendered i

Willingness to pay for health improvements of physical activity on prescription.

AIMS: To estimate the willingness to pay for health improvements among participants in the programme "Physical Activity on Prescription". The objective was also to examine predictors such as income, education level, health status, activity level and BMI, differences for long- and short-term health effects of physical activity and differences between a high- and low-intensity activity group. METHOD

C4b-binding protein in Alzheimer's disease: Binding to Abeta(1-42) and to dead cells.

In the Alzheimer's disease (AD) brain, binding of Clq within the Cl complex, the initiating molecule of the classical complement pathway, to apoptotic cells, DNA and amyloid-beta (Abeta), the major constituent of senile plaques, can initiate complement activation. However, the extent of activation is determined by the balance between activation and inhibition. Fluid-phase complement inhibitor C4b-

Crisis communication in a new world: Reaching multicultural publics through old and new media

Abstract in UndeterminedCrisis communication is a growing field of research and practice. A weakness in the traditional research field is the lack of theoretical development and the isolated sender and mass communication focus. In the present paper, we challenge traditional research by focusing on the contemporary cultural and ethnic diversity in society from an audience-oriented media perspective

Compact and low profile co-located MIMO antenna structure with polarization diversity and high port isolation

A compact co-located MIMO structure with high port isolation is proposed for 2.4 GHz WLAN application. The antenna structure consists of a proximity-coupled square ring patch antenna, and a probe fed planar inverted F antenna co-located inside. The operating frequency of the two radiators is designed to be at the same frequency, and a high port isolation below 25 dB is achieved with an extremely n
