Supplier selection and allocation of optimal order quantity are two of the most important processes in closed-loop supply chain (CLSC) and reverse logistic (RL). So that providing high quality raw material is considered as a basic requirement for a manufacturer to produce popular products, as well as achieve more market shares. On the other hand, considering the existence of competitive environ...

Protein quality control functions to minimize the level and toxicity of misfolded proteins in the cell. Protein quality control is performed by intricate collaboration among chaperones and target protein degradation. The latter is performed primarily by the ubiquitin-proteasome system and perhaps autophagy. Terminally misfolded proteins that are not timely removed tend to form aggregates. Their...

Multi-tier strategies exist in many biochemical processes to ensure a maximal fidelity of the reactions. In this review, we focus on the two-tier quality control strategy that ensures the quality of the products of the pre-mRNA splicing reactions catalyzed by the spliceosome. The first step in the quality control process relies on kinetic proofreading mechanisms that are internal to the spliceo...

Establishing and sustaining very high data quality in complex data environments is expensive and often practically impossible. Quantitative assessments of quality can provide important inputs for prioritizing improvement efforts. This study explores a methodology that evaluates both impartial and utility-driven assessments of data quality. Impartial assessments evaluate and measure the extent t...

Quality plays an important role, problems in the number of defects production cause a decrease quality. To prevent this increase defective products, it is necessary to evaluate most types determine causes so that corrective actions are obtained using statistical process control (SPC) methods and with 3 Pareto diagram controllers, charts fishbones. This research intended explore facts about Defe...
