An original heat treatment performed under vacuum pressure was investigated. Maritime pine samples were treated at six different temperatures: 140, 160, 180, 200, 230 and 260°C. The physical and mechanical consequences, i.e. bending strength (MOR), modulus of elasticity (MOE), hygroscopic behaviour, equilibrium moisture contents and anti-swelling efficiency(More)
A simple detection method of enteroviruses and adenoviruses in drinking water has been performed, using adsorption-elution on to cellulose nitrate membranes. Average of enteroviruses recovering is varying from 23 to 80% when 30 liters of water containing 60 PFU are monitored. Only 10% of adenoviruses are recovered in the same conditions. This method allowed(More)
The filtration through cellulose nitrate membranes of a poliovirus type II suspension in distilled water alone or with added mineral salts (NaCl, MgCl2, AlCl3) results in adsorption of the virus. The maximal adsorption is obtained with NaCl. A detergent in the virus suspension or a pretreatment of the membranes with calf serum prevents this adsorption.(More)
A formaldehyde-free adhesive consisting of a corn flour/NaOH adhesive mixture and a mimosa tannin/hexamine intermediate component was developed and evaluated for application to wood panels such as particleboards. The main ingredients of this adhesive include corn flour, NaOH, mimosa tannin and hexamine. This study investigated the physical properties(More)
