Particle Size Calibration between the Aerodynamic Particle Sizer and Optical Microscope for Wind Tunnel Studies with Particles of Fused Alumina

Abstract When studying the deposition of particles in wind tunnel experiments, we measure theairborne particles with an Aerodynamic Particle Sizer (APS). The deposited particles are examined with an optical microscope connected to an image analyzer. Calibration between the APS and the optical microscope determinations of particle size has been performed for particles of fused alumina. The particle

Transient Receptor Potential A1 and Cannabinoid Receptor Activity in Human Normal and Hyperplastic Prostate: Relation to Nerves and Interstitial Cells.

BACKGROUND: Ion channel transient receptor potential A1 (TRPA1) and cannabinoid (CB) receptors are involved in mechanoafferent signaling from the bladder and the urethra. OBJECTIVE: To characterize TRPA1-, CB1-, and CB2-receptor activities in the human prostate. DESIGN, SETTING, AND PARTICIPANTS: Prostate specimens were obtained from 12 patients undergoing radical prostatectomy. We studied express

A Head-to-Head Comparison of Hydrogen Peroxide Vapor and Aerosol Room Decontamination Systems.

Objective. New technologies have emerged in recent years for the disinfection of hospital rooms and equipment that may not be disinfected adequately using conventional methods. There are several hydrogen peroxide-based area decontamination technologies on the market, but no head-to-head studies have been performed. Design. We conducted a head-to-head in vitro comparison of a hydrogen peroxide vapo

Functional implications of the p.Cys680Arg mutation in the MLH1 mismatch repair protein.

In clinical genetic diagnostics, it is difficult to predict whether genetic mutations that do not greatly alter the primary sequence of the encoded protein causing unknown functional effects on cognate proteins lead to development of disease. Here, we report the clinical identification of c.2038 T>C missense mutation in exon 18 of the human MLH1 gene and biochemically characterization of the p.Cys

Sjuka barn. Om hur mediala och personliga erfarenheter vävs samman

In the end of the 1990ths came alarming reports that the vaccine against measles, mumps and rubella (MMR) could cause autism. The discovery about the connection was told in mass media all over the world and in Europe the vaccination frequency decreased with several percent. In some areas less than 90% of the children were vaccinated, a limit that calls “herd immunity”. In interviews with parents,

Plus(s) at(t) i skandinaviska — en minimal matris.

The word plus(s) can function as a conjunction in Scandinavian, and as such coordinate for example embedded clauses introduced by the subjunction at(t). However, one can also find examples of clauses introduced by plus(s) at(t) although not preceded by another at(t)-clause. These constructions, which represent a relatively new development in Scandinavian, are semantically similar to coordinations

TOTALL: high cost of allergic rhinitis-a national Swedish population-based questionnaire study.

Allergic rhinitis is a global illness with a well-recognised impact on quality of life and work performance. Comparatively little is known about the extent of its economic impact on society. The TOTALL study estimates the total cost of allergic rhinitis using a sample representing the entire Swedish population of working age. A questionnaire focused on allergic rhinitis was mailed out to a random
