Variable-range hopping is a model used to describe carrier transport in a disordered semiconductor or in amorphous solid by hopping in an extended temperature range. [1] It has a characteristic temperature dependence of. where is the conductivity and is a parameter dependent on the model under consideration.
The Perkins 4.236 is rated at 67 PS (49 kW; 66 bhp) ASE ( DIN ), and is widely used in Massey Ferguson tractors, as well as other well-known industrial and agricultural machines, e.g. Clark, Manitou, JCB, Landini and Vermeer .
A reflow oven is a machine used primarily for reflow soldering of surface mount electronic components to printed circuit boards (PCBs). In commercial high-volume use, reflow ovens take the form of a long tunnel containing a conveyor belt along which PCBs travel. For prototyping or hobbyist use PCBs can be placed in a small oven with a door.
The Volvo Modular Engine is a family of straight-four, straight-five, and straight-six automobile piston engines that was produced by Volvo Cars in Skövde, [15] Sweden from 1990 [16] until 2016. All engines feature an aluminum engine block and aluminum cylinder head, forged steel connecting rods, aluminum pistons and double overhead camshafts. [16]
The various standard phrases, to describe oven temperatures, include words such as "cool" to "hot" or "very slow" to "fast". For example, a cool oven has temperature set to 200 °F (90 °C), and a slow oven has a temperature range from 300–325 °F (150–160 °C). A moderate oven has a range of 350–375 °F (180–190 °C), and a hot oven has temperature set to 400–450 °F (200–230 °C ...
Thermal profiling. A thermal profile is a complex set of time-temperature data typically associated with the measurement of thermal temperatures in an oven (ex: reflow oven ). The thermal profile is often measured along a variety of dimensions such as slope, soak, time above liquidus (TAL), and peak. A thermal profile can be ranked on how it ...

The 440-T4 was originally slated to be used with downsized C-Body cars for 1984. However, issues with failures due to lack of fluid lubrication to critical clutch train parts in the relatively complex and compact design, led to the introduction of transverse FWD 4-speed automatics being delayed as an option until 1984 for the 1985 model year.
