Pseudogenes are considered to be nonfunctional genes that lack a physiological role. By screening 3985 Escherichia coli mutants using chemochromic membranes, we found four pseudogenes involved in hydrogen metabolism. Knockouts of pseudogenes ydfW and ypdJ had a defective hydrogen phenotype on glucose and formate, respectively. Also, the knockout of pseudogene yqiG formed hydrogen from formate b...

background: optimal allocation of resources commensurate with performance improvement is the concerns of all countries including iran. estimation hospitals production function is important in the economic management of hospitals. objective: the aim of this study was to estimate the production function of iranian selected public hospitals as well as analyze the economic behavior in use of hospit...

Takt production and decentralized decision-making have been recent areas of interest in (lean) construction management research. Both the potential to improve flow contribute increased performance. Despite interest, efforts toward decentralization not effectively considered first-line workers; simultaneously, takt studies suggest that neglection workers’ involvement has led implementation chall...

In manufacturing institutes the only access way to maximum profit is identifying the production mix of the products based on the limitations such as policies and politics, demand and production processes. This study identifies the constraints of a tile-manufacturing company including constraints in its production and demand line using LINGO software version 15, and identifying production bottle...

Data of four layers flocks (#31-34) from North Carolina Layer Performance and Management Test of the Department of Agriculture and Consumer Services were used in the meta-analysis to find if an increase in space allowance can affect egg production traits in white and brown layers. Effects of space allowance of 310 and 413 cm2/bird on layers performance were compared in this study. The increase ...

The approach presented in this paper helps companies to systematically evaluate whether a restructuring of a production is desirable or the optimization of the production processes in the current structure should be preferred. Based on the results the companies’ decision for or against restructuring the production will be facilitated.
