Purpose: The purpose of this paper is to explore the processes of value creation and appropriation among companies in a reverse clothing supply chain. Design/methodology/approach: This research is based on an inductive case study approach at fashion retailers, charity organisations, commercial recyclers, and specialised sorting companies involved in take back schemes for used clothes in the rev...
BACKGROUND The risk of hepatotoxicity associated with different highly active antiretroviral therapy (HAART) regimens (containing multiple-protease inhibitors, single-protease inhibitors or non nucleoside reverse transcriptase inhibitors) in HIV-HCV co-infected patients has not been fully assessed. METHODS Retrospective analysis of a prospective cohort of 1,038 HIV-HCV co-infected patients wh...
Ž . We demonstrate that heteroand homonuclear NMR spectra of cyclosporin A and pancreatic trypsin inhibitor BPTI can be recorded at room temperature in liquid CO , a medium of very low viscosity, which has been reported to have no adverse 2 effect on molecular structure or activity of several proteins. Rotational diffusion of cyclosporin A in a CO rmethanol 2 mixture is approximately three-fold...
The magnetic properties of a thin film consisting of an exchange-coupled [Co/Ni]2/NiFe multilayer has been studied as a function of the NiFe thickness by using Monte Carlo modeling and compared with experimental results of [Co/Ni]4/Co/NiFe multilayers. Both modeling and experiment showed that the NiFe thickness controls the effective anisotropy. The direction of the easy axis is determined by a...
biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...
Highly dispersed cobalt-silicon mixed oxide [Co-SiO2] nanosphere was successfully prepared with a modified reverse-phase microemulsion method. This material was characterized in detail by X-ray diffraction, transmission electron microscopy, Fourier transform infrared, ultraviolet-visible diffuse reflectance spectra, X-ray absorption spectroscopy near-edge structure, and N2 adsorption-desorption...

زمینه و اهداف: امروزه لاکتوباسیلوس ها ی پروبیوتیکی به علت داشتن خصوصیات ضد میکروبی و به ویژه تجمع پذیری که از اتصال اولیه و استقرار باکتری های بیماری زا در بدن میزبان جلوگیری می کنند. هدف از این مطالعه، بررسی اثر ضدمیکروبی و تجمع پذیری باکتری های پروبیوتیکی لاکتوباسیلوس پلانتاروم ptcc 1058 و لاکتوباسیلوس کازه ایptcc 1608 و نیز جدایه های لاکتوباسیلوسی محصولات لبنی شهرستان سبزوار بر روی برخی از ...
The reforming of methane with CO2 was carried out efficiently in a fluidized bed reactor at 973 K under atmospheric pressure, taking advantage the nickel catalyst efficiency achieved particulate fines. fluidization operation characterized by determining minimum velocity 3.11 × 10−3 ms−1 and higher velocities. worked surface speeds up to 1.84 10−2 ms−1, providing conversions from 45% 51% syngas ...
In this study a supply chain network design model has been developed considering both forward and reverse flows through the supply chain. Total Cost, environmental factors such as CO2 emission, and social factors such as employment and fairness in providing job opportunities are considered in three separate objective functions. The model seeks to optimize the facility location proble...
