A Closed-loop Green Supply Chain Network Design Using Robust Optimization
, M.Sc. Thesis Sharif University of Technology ; Fereydoon, Kianfar (Supervisor)
Abstract
Network design is one of the major strategic decisions of a supply chain which leads to the whole sustainability of the chain. Besides, due to an increase in carbon dioxide emissions and its harmful effects, recently there has been an growing interest in green supply chain network design. In this thesis, a mixed integer linear programming is developed to formulate a closed-loop supply chain with forward and reverse logistics. Moreover, social cost rate of carbon dioxide is used to consider environmental impact. Considering uncertainty in closed-loop supply chains is crucial. To do so, three robust optimization methods including Soyster, Ben-tal and Nemirovski and Bertsimas and Sim approaches...

Abstract
The history of plants to be utilized as medicines is thousands of years old. Black cumin is one of the most widely examined plant possessing naturally occurring compounds with antimicrobial potential. Foliar application of growth stimulators is a successful strategy to enhance yield and quality in many crops. A field study was planned to apply growth stimulator like moringa leaf extract on black cumin crop grown under field conditions using RCB design with three replications. All other agronomic inputs and practices were uniform. The treatments were moringa leaf extract concentrations (10%, 20%), growth stages (40 days after sowing, 80 DAS, 120 DAS, 40 + 80 DAS, 40 + 120 DAS, 80 + 120 DAS,...

Abstract
Silver nanoparticles (Ag. NPs) have shown a biological activity range, synthesized under different environment-friendly approaches. Ag. NPs were synthesized using aqueous crude extract (ACE) isolated from Plantago lanceolata. The ACE and Ag. NPs were characterized and assessed their biological and antioxidant activities. The existence of nanoparticles (NPs) was confirmed by color shift, atomic force microscopy (AFM), and UV–Vis’s spectroscopy. The FT-IR analysis indicated the association of biomolecules (phenolic acid and flavonoids) to reduce silver (Ag+) ions. The SEM study demonstrated a sphere-shaped and mean size in the range of 30 ± 4 nm. The EDX spectrum revealed that the Ag. NPs were...
