Various methods, including autoclaving, bead-beating, microwaves, sonication, and a 10% NaCl solution, were tested to identify the most effective cell disruption method. The total lipids from Botryococcus sp., Chlorella vulgaris, and Scenedesmus sp. were extracted using a mixture of chloroform and methanol (1:1). The lipid contents from the three species were 5.4-11.9, 7.9-8.1, 10.0-28.6, 6.1-8...

Microscopic model of the interaction spins with a microwave field in random-anisotropy magnet has been developed. Numerical results show that absorption occurs broad range frequencies due to distribution ferromagnetically correlated regions on sizes and effective anisotropy. That is also responsible for weak dependence damping. At fixed frequency ac-field, spin oscillations are localized inside...

This paper proposes to transform microwaves for snow melting, which slightly leaking from the slotted waveguide, into electric power using a wireless transmission technique effective use. A combination of left-handed and right-handed waveguides is method melt evenly over large area microwaves. The however, has loss because stubs. In order evaluate effect waveguide’s loss, this analyzed efficien...

It is shown that microwave irradiation can affect the kinetics of the folding process of some globular proteins, especially beta-lactoglobulin. At low temperature the folding from the cold denatured phase of the protein is enhanced, while at a higher temperature the denaturation of the protein from its folded state is enhanced. In the latter case, a negative temperature gradient is needed for t...
