	Encyclopedia: Turbo Direct Injection
		Direct injection diesel engines operate by having the fuel injector arranged to inject fuel directly into the engine's cylinder, as opposed to indirect injection diesel engines, where the fuel is injected into a pre-combustion chamber.
		The reduced material volume of the direct injection diesel engine reduces heat losses and thereby increases engine efficiency, at the expense of increased combustion noise.
		A direct injection engine is also easier to start when cold, due to the reduced heat loss of the design.

		The connecting rod transmits this motion to the crankshaft which is forced to turn, delivering rotary power at the output end of the crankshaft.
		(See direct injection vs indirect injection for a discussion of the types of fuel injection.) To fully realize the capabilities of a diesel engine, use of a turbocharger to compress the intake air is necessary; an aftercooler/intercooler to cool the air after compression further increases efficiency.
		Their use of electronic ignition, fuel injection, and sophisticated engine management systems also makes them far easier to operate than mass-produced spark-ignition aircraft engines, most of whom still use carburettors.

	Fuel Injection
		Indirect fuel injection is the familiar system wherein the injectors are placed in the intake ports.
		Direct injection on the other hand is the diesel-style system, now increasingly found in two-stroke application, which has the injectors in the combustion chamber.
		Direct injection's advantage is that with injection so vigorous, the two-stroke engine's exhaust port can be allowed to close before the mixture is injected, greatly reducing exhaust emissions.

		Smaller diesels are increasingly adopting direct injection (vs. indirect injection into a pre-chamber).
		Direct Injection can also be used in spark ignition (generally gasoline) engines instead of port fuel injection - for improved fuel economy, increased full throttle torque and power and potentially for better fuel economy with lean-burn operation.
		DIRECT INJECTION : With the Direct injection Spark Ignition (DISI) engines, fuel is injected in one of two ways, depending on operating conditions.

	Supreme Law Library : Decisions : U.S. v. Lopez : lopez
		At the midpoint of the 19th century, the Court embraced the principle that the States and the National Government both have authority to regulate certain matters absent the congressional determination to displace local law or the necessity for the Court to invalidate local law because of the dormant national power.
		V This extended discussion of the original understanding and our first century and a half of case law does not necessarily require a wholesale abandonment of our more recent opinions.
		The Court's finding that the regulated activity had a direct enough effect on commerce has since been seen as beginning the abandonment, for practical purposes, of the formalistic distinction between direct and indirect effects.

		Mounted on the injection unit’s 30:1 L/D fixed-screw extruder, the screenchanger protects hot runners and small gates from regrind contaminants, while eliminating any possible pressure drop that might be encountered when using a screenchanger or filter in front of a conventional shooter.
		Large shot capacities, injection pressures of more than 29,000 psi, a maximum injection speed of 10 in/sec, and a more than 30 percent greater screw rotation torque vs. comparable hydraulic shooters are benefits of the design.
		Functions including injection unit displacement, injection, hold- and backpressure, and screw pullback are handled by accumulator-assisted hydraulics with a digital servovalve and full closed loop control.

	Anabolic Steroid Information: Direct and Indirect Anabolic Effects
		An indirect mechanism is one that is not directly brought about by activation of the androgen receptor, but the affect androgens might have on other hormones, or even the release of locally a hormones or growth promoters inside cells (perhaps mediated by other membrane bound receptors).
		Although perhaps not itself technically considered an anabolic effect as tissue hypertrophy is not a direct result, androgen support of creatine synthesis is certainly still looked at as a positive and growth supporting result in the mind of the bodybuilder.
		I believe the theory behind direct and indirect steroid classifications originated when some noted the low receptor binding affinity of seemingly strong anabolic steroids like oxymetholone and methandrostenolone If they bind poorly, yet work well, something else must be at work.

		In mathematics, the term injection refers to an injective function.
		In medicine, an injection is a method of putting liquid into the body with a hollow needle and a syringe.
		However, people should try to use the same body area for injections that are given at the same time each day-for example, always using the stomach for the morning injection or an arm for the evening injection.

		EBM processes may be either continuous (constant extrusion of the parison, as on wheel or shuttle machinery) or intermittent (such as on reciprocating screw exrusion or accumulator machinery.) Examples of parts made by the EBM process include dairy containers, personal care bottles, and hollow industrial parts such as drums.
		In the Injection Blow Molding (IBM) process, the polymer is injection molded onto a core pin; then the core pin is rotated to a blow molding station to be inflated and cooled.
		The numerous spores released by mold do not cause direct harm in humans, but the hyphae grown from those spores can attach to cells along the respiratory tract and cause problems in those with weak immunity.

	Turbo Direct Injection - Encyclopedia, History, Geography and Biography
		Direct injection engines have the fuel injector mounted in the cylinder wall, instead of behind intake valves.
		This results in locally heavy concentrations of fuel, enabling for compression detonation, but the average fuel-air mixture over the combusiton chamber is lower, enabling a more complete burn and higher fuel efficiency.

		Dagenhart, 247 U.S. however, the Court insisted that the power to regulate commerce "is directly the contrary of the assumed right to forbid commerce from moving," id., at 269-270, and struck down a prohibition on the interstate transportation of goods manufactured in violation of child labor laws.
		Filburn, 317 U.S. 111 (1942), the Court disapproved E.C.

		On the TDI (I have a Jetta TDI Wagon) there is a solenoid on the injection pump that relieves the pressure once the correct amount of fuel has been delivered, which eliminates the smoke from overfueling when you floor it.

	Lexicon of Evolutionary Genetics
		Secondary sexual characters may be more susceptible to disruption during development because they are subject to directional selection which would select against modifiers that may buffer development (non-sexually selected traits are developmentally canalised by genetic modifiers); and mutations are more likely to have a disruptive effect on characters which are elaborate in design.
		When a new population is derived from a few immigrants, these founders represent a very small sample of the genetic pool to which they formally belonged; natural selection operating on this restricted variety soon yields gene combinations quite different from those found in the ancestral population, or those of a second small sample of founders.
		Selection for traits which are solely concerned with increasing mating success, either by favouring the ability of one sex (usually males) to compete directly with one another for fertilisations, for example by fighting (intra-sexual selection), or by favouring traits in one sex which attract the other (inter-sexual selection: see MATE CHOICE).
