The goal of this research is to determine how tiredness behavior may be measured (PLA). A To variety technical data sets were S-N curves chosen and statistically re-analyzed. as described in the following section, generate a negative reference value reverse slope also an improved tolerance limit 106 2 failure cycles. average effect stress on fatigue can indicated via administering highest level...

Drug carrier biocompatible and biodegradable nanoparticles of about 15 nm were prepared by solvent evaporation technique from star-shaped poly(D,L-lactide) synthesized using dipentaerythritol as core and Tin (II) ethylhexanoate as catalyst.

We propose a new type of ammonia sensor based on composite film between polyaniline (emeraldine base) dissolved in dimethylformamide, and poly(DL-lactic) acid dissolved in chloroform. The two solutions were mixed in weight ratio of the components 1:1 and cast on Al2O3 substrate, on which silver electrodes were deposited previously. The active layer structure and morphology were examined by atom...

Vaginal dilation is proposed as the first choice treatment for patients with vaginal aplasia, but many patients with MRKH or Rokitansky syndrome (and cases with CAIS) may require a vaginoplasty. It is also necessary to make vaginoplasty in patients with vaginal or cervicovaginal atresia with a functional uterus before performing an utero-neovaginal anastomosis, also in trans-sexual men.

PLA biocomposites were prepared using three corn cob fractions and a wood fiber as reference. The composites were characterized by tensile testing, scanning electron microscopy (SEM) and polarization optical microscopy (POM). Micromechanical deformation processes were followed by acoustic emission measurements. The different strength of the components was proved by direct measurements. Two cons...
