Within this alliance, both companies will enhance the use of microbiological diagnostic products based on liquid collection devices and incorporates innovative transportation Copan (as ESwab) for use in combination with the platform and quantification identification in real time POCAR. Copan POCAR alliance and also introduce a new level of
automation and ease of use.

"Copan has a personal interest in the development of devices and technologies essential for the diagnosis and quantitative laboratory workflow streamlined. The technology developed by POCAR is highly complementary to our concept of microbiology-based liquid," said Daniele Trive, CEO Copan Group.

The cooling towers are aiming to lower the temperature of the hot water comes from a cooling circuit through the heat and mass transfer to the air that circulates inside the tower. To improve the air-water contact, using a fabric called "stuffed." Water enters the tower at the top and spread evenly over the filling using sprayers. Thereby achieving a good contact between water and atmospheric air.

The filler serves to increase the time and area of exchange between water and air. Once the contact between water and air, a constant heat transfer from water to air. This occurs because of two mechanisms: convection heat transfer and the transfer of water vapor from the air, thereby cooling the water due to evaporation.

The permeability of water swollen segmented polyurethane membranes has been determined for the solutes urea, glucose, sucrose, and raffinose at 26.5[degrees]C. The permeability of segmented polyurethane membranes; based on poly(oxyethylene glycol) grades 600, 1000, 1500, and 1540; was determined for the swollen unstrained films and for the swollen films at several strains. The free volume theory for diffusion through homogeneously swollen polymers was able to predict the observed changes in membrane permeability with strain for all solutes except urea. The free volume theory fails to predict the urea data accurately because the polyurethanes used absorb urea and therefore the urea can diffuse through the polymer as well as through the solvent, an eventuality not provided for in the free volume theory.
