v. t. e. Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter ( WEC ). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations ...
Zero waste. Zero waste, or waste minimization, is a set of principles focused on waste prevention that encourages redesigning resource life cycles so that all products are repurposed (i.e. “up-cycled”) and/or reused. The goal of the movement is to avoid sending trash to landfills, incinerators, oceans, or any other part of the environment.
Calculator input methods. There are various ways in which calculators interpret keystrokes. These can be categorized into two main types: On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown.

Bottom right: completed solar wafers. In electronics, a wafer (also called a slice or substrate) [ 1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells . The wafer serves as the substrate for microelectronic devices ...
Say you earn an income of $2,000 a month. Following the 50/30/20 rule would mean allocating $1,000 to needs, $600 to wants and $400 to savings or high-interest debt. But if your monthly rent and ...
Casio V.P.A.M. calculators are scientific calculators made by Casio which use Casio's Visually Perfect Algebraic Method (V.P.A.M.), Natural Display or Natural V.P.A.M. input methods. V.P.A.M. is an infix system for entering mathematical expressions, used by Casio in most of its current scientific calculators.
A solar power tower consists of an array of dual-axis tracking reflectors ( heliostats) that concentrate sunlight on a central receiver atop a tower; the receiver contains a heat-transfer fluid, which can consist of water-steam or molten salt. Optically a solar power tower is the same as a circular Fresnel reflector.
The reaction occurs with retention of stereochemistry, so the product lisdexamfetamine exists as a single stereoisomer. There are many possible names for lisdexamfetamine based on IUPAC nomenclature, but it is usually named as N-[(2S)-1-phenyl-2-propanyl]-L-lysinamide or (2S)-2,6-diamino-N-[(1S)-1-methyl-2-phenylethyl]hexanamide.
