An Integrated Inventory Model with Controllable Lead time and Setup Cost Reduction for Defective and Non-Defective Items

In this paper, the study deals with the lead time and setup reduction problem in the vendor-purchaser integrated inventory model. The cost of capital (i.e., opportunity cost) is one of the key factors in making the inventory and investment decisions. Lead time is an important element in any inventory system. The proposed model is presents an integrated inventory model with controllable lead tim...

Combined UHV/high-pressure catalysis setup for depth-resolved near-surface spectroscopic characterization and catalytic testing of model catalysts.

An ultra-high vacuum (UHV) setup for "real" and "inverse" model catalyst preparation, depth-resolved near-surface spectroscopic characterization, and quantification of catalytic activity and selectivity under technologically relevant conditions is described. Due to the all-quartz reactor attached directly to the UHV-chamber, transfer of the catalyst for in situ testing without intermediate cont...

Effect of Fluorination Treatment on Cotton Wettability, Dyeability and Mechanical Properties and Characterization of Surface Changes by XPS

Cotton fabric was treated with fluorine gas in a nitrogen atmosphere. The effect of fluorination treatments on wettability, whiteness index, dyeability and mechanical properties of cotton fabrics were assessed. Kawabata analysis shows that fluorination treatment increases shear stiffness G, shear hysteresis 2HG5, bending stiffness B and overall fabric stiffness Koshi on cotton fabric. Fluorinat...

Optimization of the Glycyrrhizic Acid Extraction from Licorice by Response Surface Methodology

This study aims to extract Glycyrrhizic Acid (GA) from Glycyrrhiza glabra L. (licorice) using a novel, high efficiency, and low-cost extraction method. Water was chosen as the proper solvent for the extraction process to eliminate the requirement of harmful and toxic solvents, prepare an environmentally friendly process, and reduce the costs. The effect of differe...
