Microwave ovens have a limited role in professional cooking, [2] because the boiling-range temperatures of a microwave oven do not produce the flavorful chemical reactions that frying, browning, or baking at a higher temperature produces. However, such high-heat sources can be added to microwave ovens in the form of a convection microwave oven.
It can be heard as low-frequency noise and becomes a serious problem when playing records on audio systems with a good low-frequency response. Even when not audible, rumble can cause intermodulation, modulating of the amplitude of other frequencies. The ‘unweighted’ response curve is intended for use in assessing the level of inaudible ...
Samsung Electronics is part of Samsung. In 2003, combined revenues for Samsung Electronics were $55 billion. Samsung Electronics UK is a subsidiary of Samsung Electronics contributing $1.2 billion in revenues. Samsung Electronics has one of the highest R&D expenditure as a proportion of revenues in the industry and spent about $2.9 billion in ...
Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter , but such systems are expensive and generally used only in ...

In a direct-drive turntable the motor is located directly under the center of the platter and is connected to the platter directly. It is a significant advancement over older belt-drive turntables for turntablism, since they have a slower start-up time and torque, and are prone to wear-and-tear and breakage, [5] as the belt would break from backspinning or scratching.

In microwave-excited lighting systems, such as a sulfur lamp, a magnetron provides the microwave field that is passed through a waveguide to the lighting cavity containing the light-emitting substance (e.g., sulfur, metal halides, etc.). Although efficient, these lamps are much more complex than other methods of lighting and therefore not ...
Turntablism as it is known today, however, did not surface until the advent of hip hop in the 1970s. Examples of turntable effects can also be found on popular records produced in the 1960s and 1970s. This was most prominent in Jamaican dub music of the 1960s, [6] among deejays in the Jamaican sound system culture.
