Abstract We present a study of the controlled biodegradation polylactic acid (PLA) reinforced with high lignin containing microfibrillated cellulose (MFLC) isolated from chemi-thermomechanical pulp. The surface MFLC was modified using an acetylation method to decrease its polarity. Biocomposites different and acetylated (Ac-MFLC) contents were fabricated via solvent casting method. biocomposite...
Abstract The aim of the present study is to develop a test method suitable for modelling thermoforming processes and which provides an index that accurately characterises thermoformability film or sheet at given temperature pressure. For this purpose, elevated pneumatic deformability was considered be most suitable. During test, blown until it tears, takes only few seconds. We recorded blowing ...
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...
Injectable dermal filler materials consist of either fluids, biological fragments, or suspensions of particles or microspheres. Particles and microspheres are said to "migrate," but migration can occur only when they are injected into blood vessels. To evaluate biocompatibility and transport, five nonresorbable polymethylmethacrylate microspheres of various sizes, suspended in different carrier...
BACKGROUND Hepatocellular carcinoma is difficult to diagnose early, and most patients are already in the late stages of the disease when they are admitted to hospital. The total 5-year survival rate is less than 5%. Recent studies have showed that brucine has a good anti-tumor effect, but high toxicity, poor water solubility, short half-life, narrow therapeutic window, and a toxic dose that is ...
