Background: Honey is a natural product, but it can be adulterated or heat-treated, both of which damage the properties of the original product. This research was focused on the evaluation of quality parameters of some commercial honeys produced in México.  Methods: Fifteen samples of commercial honeys available in Mexican market were collected. Some physicochemical parameters were determined, ...

Electrostatic behavior of a collisionless plasma in the foot region of high Mach number perpendicular shocks is investigated through the two-dimensional linear analysis and electrostatic particle-in-cell (PIC) simulation. The simulations are double periodic and taken as a proxy for the situation in the foot. The linear analysis for relatively cold unmagnetized plasmas with a reflected proton be...

Abstract -- Overheating is one of the causes damage or decreased performance on vehicle. This can occur due to a lack water in radiator leak. Generally, overheating occurs vehicles manufactured before 2000 because they do not have protection warning case excessive temperature. Vehicles with production years usually only temperature indicator form pointer scale. In addition overheating, voltage ...
