Distinction between enzymically and chemically catalyzed interesterification

The 1,3-specific lipase-catalyzed interesterified fats were distinguished from chemically catalyzed products by the fatty acids in the 2-position. The fatty acid contents in the 2-position of the 1,3-lipase-catalyzed and the original triglycerides were similar but different from that of chemically interesterified fat. Also, the saturated-to-unsaturated fatty acid ratio in the 2-monoglycerides was lower for the 1,3-specific lipase-catalyzed interesterified fats than for the corresponding chemical products.

Copper-induced green hair. Treatment with a penicillamine containing shampoo

A male patient with green hair is described. The cause was exogenous deposition of copper from domestic tap water which contained an increased copper concentration. The discolouration disappeared promptly following the use of a penicillamine containing shampoo.     

Flexible generation mix under multi objectives and uncertainties

Criteria for evaluating flexibility of a generation mix are presented, and an efficient computational algorithm for determining a flexible generation mix considering uncertainties in the power system expansion planning is developed. The flexible generation mix problem is formulated as a multiobjective optimization problem and solved by the dynamic programming technique in which type of generation plant is selected as a stage and generation capacity is selected as a state. The proposed method can treat easily not only the uncertainties but also many constraints of generation planning such as integer solutions of generation capacities, reliability constraints, and so on. The effectiveness and feasibility of the proposed method are demonstrated on a typical power system model     

Laser interferometer with fine-focused beams to monitor the spatial position of an object

Analogies with interferometers using a light source with low temporal coherence are used to analyze the principles of the construction of laser interferometers with averaging over the photodetector aperture, whose sensitivity to the position of an object being monitored at the maximum of the output signal is as good as that of low-coherence interferometry and tomography.
