Effects of type of machine and covering on viruses and microorganisms recovered from dust in ultrasound machines used in German swine production operations
نویسنده
چکیده
Methods: Dust swabs were collected from 18 ultrasound machines of three common types. Five were used completely covered (closed plastic bags or household plastic cling-film), four incompletely covered (with open or perforated plastic bags), and nine uncovered. Swabs were tested for porcine circovirus type 2 (PCV-2) by polymerase chain reaction (PCR), for porcine reproductive and respiratory syndrome virus (PRRSV) by nested reverse transcriptase-PCR, and for bacteria, fungi, and yeasts by culturing. Eight new unused machines (two or three of each type) served as negative controls.

Machine Cell Formation Based on a New Similarity Coefficient
One of the designs of cellular manufacturing systems (CMS) requires that a machine population be partitioned into machine cells. Numerous methods are available for clustering machines into machine cells. One method involves using a similarity coefficient. Similarity coefficients between machines are not absolute, and they still need more attention from researchers. Although there are a number o...

متن کاملOptimality of the flexible job shop scheduling system based on Gravitational Search Algorithm
The Flexible Job Shop Scheduling Problem (FJSP) is one of the most general and difficult of all traditional scheduling problems. The Flexible Job Shop Problem (FJSP) is an extension of the classical job shop scheduling problem which allows an operation to be processed by any machine from a given set. The problem is to assign each operation to a machine and to order the operations on the machine...
