A close-up view of grains steeping in warm water during the mashing stage of brewing. In brewing and distilling, mashing is the process of combining ground grain – malted barley and sometimes supplementary grains such as corn, sorghum, rye, or wheat (known as the "grain bill") – with water and then heating the mixture.
In brewing, decoction mashing is the traditional method where a portion of the mash is removed to a separate vessel, boiled for a time and then returned to the main mash, raising the mash to the next temperature step. [citation needed] In herbalism, decoctions are usually made to extract fluids from hard plant materials such as roots and bark. [2]
As of 1992, the Laboratory Microfusion Facility was estimated to cost about $1 billion. [67] LLNL initially submitted a design with a 5 MJ 350 nm (UV) driver that would be able to reach about 200 MJ yield, which was enough to attain the majority of the LMF goals.That program was estimated to cost about $600 million FY 1989 dollars.
Infusion is a chemical process that uses botanicals (typically dried herbs, flowers or berries) that are volatile and release their active ingredients readily in water, oil, or alcohol. In this process, a liquid is typically boiled (or brought to another appropriate temperature) and poured over the herb.
Process design can be the design of new facilities or it can be the modification or expansion of existing facilities. The design starts at a conceptual level and ultimately ends in the form of fabrication and construction plans. Process design is distinct from equipment design, which is closer in spirit to the design of unit operations.
The result of the mashing process is a sugar-rich liquid or "wort", which is then strained through the bottom of the mash tun in a process known as lautering. Prior to lautering, the mash temperature may be raised to about 75–78 °C (167–172 °F) (known as a mashout) to free up more starch and reduce mash viscosity.
In this instance the rate of flow is usually controlled by a clamp on the infusion tubing; this affects the resistance to flow. However, other sources of resistance (such as whether the vein is kinked or compressed by the patient's position) cannot be so directly controlled and a change in position may change the rate of flow leading to ...
Stem, progenitor, or mature cell engraftment, differentiation, and long-term replacement of damaged tissue. In this paradigm multipotent or unipotent cells differentiate into a specific cell type in the lab or after reaching the site of injury (via local or systemic administration).
