Blast chilling is a method of cooling food quickly to a low temperature that is relatively safe from bacterial growth. Bacteria multiply fastest between +8 and +68 °C (46 and 154 °F). By reducing the temperature of cooked food from +70 to +3 °C (158 to 37 °F) or below within 90 minutes, the food is rendered safe for storage and later ...
BLAST (biotechnology) In bioinformatics, BLAST ( basic local alignment search tool) [ 3] is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.
Blast furnace gas. Blast furnace gas (BFG) [1] is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value, about 93 BTU /cubic foot (3.5 MJ/m 3 ), [2] because it consists of about 51 vol% nitrogen and 22 vol% carbon dioxide, which are not flammable. The rest ...
In 1990, 2.1 billion kg of commercial explosives were consumed in the United States (12 m 3 per capita), representing an estimated expenditure of 3.5 to 4 billion 1993 dollars on blasting. In this year the Soviet Union was the leader in total volume with 2.7 billion kg of explosives consumed (13 m 3 per capita), and Australia had the highest ...
Hot blast allowed the use of anthracite in iron smelting. It also allowed use of lower quality coal because less fuel meant proportionately less sulfur and ash. [11]At the time the process was invented, good coking coal was only available in sufficient quantities in Great Britain and western Germany, [12] so iron furnaces in the US were using charcoal.
A blast gate is a gate valve used to focus a dust collection system 's vacuum pressure for maximum dust (or other material) extraction at the desired location. Blast gates are positioned near individual pieces of machinery and operate by being closed by default, blocking air flow. When one blast gate is opened, all available suction is focused ...
The Berkeley Lazy Abstraction Software verification Tool ( BLAST) is a software model checking tool for C programs. The task addressed by BLAST is the need to check whether software satisfies the behavioral requirements of its associated interfaces. BLAST employs counterexample -driven automatic abstraction refinement to construct an abstract ...
