Two different mechanisms were responsible for the disappearance of styrene in enrichment cultures: (i) a mixed population of microorganisms, capable of utilizing styrene as a sole carbon source, oxidized this substrate to phenylethanol and phenylacetic acid; (ii) the culture also mediated polymerization of the monomer to low-molecular-weight styrene oligomers. This chemical reaction probably oc...

objective(s): auraptene, a monoterpene coumarin from citrus species, exhibits cardioprotective effects.in this study, the effects of auraptene administration were investigated on blood pressure of normotensive and desoxycorticosterone acetate (doca) salt induced hypertensive rats. materials and methods: five weeks administration of auraptene (2, 4, 8 and 16 mg/kg/day) and nifedipine (0.25, 0.5,...

The authors present the first prospective, randomized, controlled study comparing postoperative dynamic versus static splinting outcomes of patients following extensor tendon repair. Patients who incurred simple and complete lacerations of their extensor tendons in zones V and VI were enrolled into the study and underwent either static splinting (n = 17) or dynamic splinting (n = 17) following ...

The paper presents a new multiplier enabling achievement of an arbitrary accuracy. It follows the same idea of number representation as the Mitchell’s algorithm, but does not use logarithm approximation. The proposed iterative algorithm is simple and efficient and its error percentage is as small as required. As its hardware solution involves adders and shifters, it is not gate and power consum...
