Preliminary experiments on spinning bacterial proteins into fibers

Fabrication of κ-Carrageenan Fibers by Wet Spinning: Spinning Parameters

This study demonstrates the fabrication of κ-carrageenan fibers by a wet-spinning method and discusses three important spinning parameters: coagulation bath composition, spinning rate and post-spinning mechanical drawing. The as-spun fiber diameter decreased with KCl and ethanol concentration in the coagulation bath. In general, the ultimate tensile stress and elongation at break both increased...

Experiments on bacterial denitrification.

Variable angle spinning (VAS) experiments for strongly oriented systems: methods development and preliminary results.

Variable angle spinning (VAS) experiments provide a useful method for measuring long-range dipolar couplings and obtaining isotropic-anisotropic correlation spectra. These experiments make it possible to obtain correlations between isotropic and anisotropic spectra without altering the chemical composition of the sample. They also allow working with very strongly oriented systems that are not a...

A preliminary investigation into bacterial contamination of Welsh emergency ambulances.

OBJECTIVES The objective of this regional study across Wales was to perform a preliminary examination of Welsh emergency vehicles to determine levels of bacterial contamination. METHODS Specific sites within emergency vehicles were swabbed, before and after vehicle cleaning, over a 12 month period, on a monthly basis. All swabs were sent to pathology laboratories for culturing and analysis. ...

[Continent vesicocutaneostomy. Preliminary experiments on dogs].

A new operative technique for continent urinary diversion was designed as a continent vesicocutaneostomy and preliminary experiments were performed on 7 dogs. A U-shaped flap of anterior bladder wall (30 X 20 X 30 mm) was created, which was then rolled and sutured to an efferent duct. One-half to two-thirds in length of the efferent duct was placed between the muscular layer and mucosa of the b...
