Poly(lactic acid) (PLA) and starch copolymers are obtained by reactive blending varying the starch compositions from 0 to 60%. PLA is functionalized with maleic anhydride (MA), obtaining PLA-g-MA copolymers using dicumyl peroxide as an initiator of grafting in order to improve the compatibility and interfacial adhesion between the constituents. PLAþ starch blends without a compatibilizer do not...

In addition to their role in vision, retinoids, for example, 1a–k and their derivatives, have been found to affect fetal development, cell differentiation, metabolism, and organ and cell regulation. They also provide lead structures for various anticancer, anti-inflammatory, and antibacterial drugs. In plants and food, they act as hormones, pigments, flavors, aromas, and as defense substances. ...

The radiative heat transfer in arc plasma models of a free-burning and torch atmospheric pressure argon is taken into account self-consistent way. This realized by the P1 method for solving equation multi-band approximation that considers division emitted spectrum number spectral bands. Net emission coefficients are evaluated three dimensions an isothermal cylindrical plasma. parameters obtaine...

Glioblastoma is one of the most common primary brain tumors (80% of patients) that has a poor prognosis due to malignancy. Glioblastoma has an annual incidence of 5.26 per 100 000 population or 17 000 new diagnoses per year and so as the population aging, the number of patients is expected to increase. There is a growing body of literature investigating the tumor microenvironmenta...
