All CAST components of the Tn6677 system from Vibrio cholerae have been combined into a single plasmid and confirmed to deliver up to 10kb transposons at near 100% efficiency. [16] This has also been shown in a community context with conjugative delivery of suicide vectors to provide antibiotic resistance or enhanced metabolic function to only ...
Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
Process science is the method of describing change from an inquiry-oriented process perspective. [1] [2] [3] Process science includes algorithms, heuristics, and sequences found in psychology, linguistics, anthropology, politics, and economics. [4] In sociology, processes are temporal. [5] In computer science, a process is the collective input ...

While there exists a number of materials to choose from while deploying polymer solution casting technology, the material science work continues in the areas of wall thickness, strength, lubricity, biocompatibility and clarity as well as interactions of the liquid polymers with extruded and injection molded components.

Ablation casting is a sand casting process that uses water to wash away the mold while the metal solidifies. This process produces castings with high mechanical properties, reduced defects, and a fine microstructure. Here are some steps in the ablation casting process:
In 1964, M.C. Flemmings used unbonded sand for the process. The first North American foundry to use evaporative-pattern casting was the Robinson Foundry at Alexander City , Alabama . General Motors ' first product using these processes was the 4.3 L, V-6 diesel cylinder head , which were made in 1981 at Massena , New York .
