The main purpose of this study was to investigate the optimal use of digital tools and technologies for sustainability in Supply Chain Management (SCM). To achieve this, we examined various discussions, including economic, ecological, social, legal policy, value, and technological factors related to Sustainable Supply Chain Management (SSCM). This thesis utilized a mixed-methods approach, incorporating qualitative analysis to identify and finalize the variables and measures of the research model through a systematic review of existing studies. The statistical analysis method employed SPSS software to examine relationships between variables, while structural equation modeling was conducted in... 

Flexible vegetation has a significant impact on the small-scale hydrodynamics of aquatic environments, which governs the dispersion of dissolved and particulate material. Flexible canopies bend and oscillate in both the in-line and cross-flow directions due to periodic forcing associated with vortex shedding. The resultant plant motion affects the vegetation wake structure and, hence, the rate of lateral dispersion in these environments. Despite a recently-developed understanding of dispersion in rigid canopies, a framework that can predict the effect of plant-induced vibrations on mixing in flexible canopy environments is still lacking. Here, we investigate the role of the flexibility of... 

It is assumed in many traffic assignment models that people choose their path based on shortest travel time. Few empirical studies of revealed route characteristics have been reported in the literature. In this study, first, an innovative internet-based survey using Google map has been designed and implemented. The sample includes the people who commute to Sharif University of Technology in the morning peak hours. Next, observed routes in 134 valid questionnaires have been analyzed by using Tehran network database and VBA programming. Besides the length and travel time of each path, other characteristics of the observed route such as the number of right, left, and U-turns, number of... 

The present work illustrates the results of an experimental study of ferrofluid flow in a tube subjected to a constant heat flux on its wall and filled with permeable material under the effect of magnetic field. The aim of this project is investigating the enhancement of heat transfer and obtaining a uniform temperature distribution inside the pipe. In order to achieve this, a porous medium with a porosity of 0.39 and ferrofluid with volume fractions of 0.6, 1.0 and 1.5 are used simultaneously, in the presence of magnetic field. The experiments are held for four different Reynolds numbers of 147.1, 167.3, 184.3 and 205.1. Also, four various modes of the oscillatory magnetic field are applied... 

Breast cancer is the fifth cause of death from cancer and one of the most common fatal cancers in women. The commonly drugs used to treat cancer often destroy healthy tissues and cells and cause common side effects. It is also necessary to consume a large amount of the drug to achieve a particular effect. One of the applications of nanotechnology is drug delivery. Niosomes are one of the newest drug delivery systems that are nowadays much more widely considered due to better penetration and controlled release. One of the most effective medicines for treating breast cancer is statins. These drugs are a group of lipids lowering drugs that lower the synthesis of cholesterol by inhibiting the... 

Neural system in human body due to limitated cell proliferation requires high care, because the damage causes serious hurts and disables different tissues. Limit regeneration in central neural system can cause different neural diseases including brain exhaustions specially in old people, but the peripheral neural system may have been disabled and intrupt some other tissue beacuase of possible external injuries before aging. So that while some damages like neural fibers severing, some new medical care methods are required. Some of these methods are outograft, allograft and xenograft which implants neural tissues either between other patient's tissues or from somebody else's; however these...
