A method for the in-vitro detection of the integrin subunits α2 and α4 from a biological thyroid sample is described and comprises the stages of: - incubating said biological thyroid sample with a ligand which is specific for at least one of said integrin subunits α2 and α4 in order to form a complex; - washing; - incubating said complex with means for detection of said complex; - detecting said c...

A regulator device devised in particular for motor cycles, intended to be interposed between a generator (V) which produces an alternating input signal the amplitude and frequency of which are widely variable, and a load (B) which must be supplied with a substantially constant DC voltage signal. The device comprises at least one electronic switch such as a power FET (5) interposed between the inpu...

Starting from a sequence of values of indicated torque (Ci) detected for each expected combustion in the engine a cycle signal (Di) is generated as a combination of at least two successive values of the said sequence. The peak value (PP1i) of the said cycle signal is then compared with a comparison threshold (Ca) chosen preferably in proportion to the fuel injection duration into the cylinders. Mi...

Propylene glycol monomethylether propionates are obtained by esterifying propylene glycol monomethyl ethers with propionic acid at a temperature in excess of 80 degree C in the presence of an acid catalyst and an azeotropic agent. The compounds are subjected to distillation to remove the residual acid and moisture in order to yield the desired product in high purity.
