This paper analyzes what environmental policy is implemented by governments when there cross-ownership between polluting firms that care about social concerns. We compare the equilibrium outcomes under taxes, tradable emission permits and standards. find concern of corporate responsibility (CSR), which decided endogenously, depends on government. The greatest obtained lowest also affects CSR le...

Colloidal quantum dots (CQDs) have attracted tremendous research interests in future-generation energy, electronic, optoelectronic, and bio-imaging applications due to their fascinating material properties, such as solution processability at room temperature under ambient conditions, compatibility with various functional materials, high photostability well photosensitivity. Among the optoelectr...

‎‎let $g=(v,e)$ be a simple graph‎. ‎an edge labeling $f:eto {0,1}$ induces a vertex labeling $f^+:vtoz_2$ defined by $f^+(v)equiv sumlimits_{uvin e} f(uv)pmod{2}$ for each $v in v$‎, ‎where $z_2={0,1}$ is the additive group of order 2‎. ‎for $iin{0,1}$‎, ‎let‎ ‎$e_f(i)=|f^{-1}(i)|$ and $v_f(i)=|(f^+)^{-1}(i)|$‎. ‎a labeling $f$ is called edge-friendly if‎ ‎$|e_f(1)-e_f(0)|le 1$‎. ‎$i_f(g)=v_f(...

Abstract The purpose of this study is to investigate the chemical composition Greek Naxos emery, and reuse emery in light new environmental applications discovered. Its will help us propose alternative ways exploiting using it. Emery was characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray spectroscopy (EDS) X-Ray diffraction (XRD) it revealed that elemental analysis sho...

Concrete structures’ service life lasts decades. In order to deal with all the probable degradations and deteriorations in the whole life span, the concept of concrete structures’ Life-Cycle Design was introduced into China in the 1980s. However, until this day, Life-Cycle Design is still more of a concept to most structure designers and engineers, rather than a practical method. This paper pro...

Green marketing is a recent concept which has been adopted by consumers, organizations & government all over the world to save the natural resources & to protect the environment for the sustainable development of the resources. The research purpose here is to find the environmental concern of consumers & its impact on their purchase decision while they have alternatives available for enviornmet...

Environmental sustainability and eco-friendly design are becoming increasingly important in engineering today. This paper discusses green design in the KAIST Freshman Design Program. It is shown that students and faculty members tend to choose green design projects, even when not required. Students have successfully adapted general design processes and formal design theories to eco-friendly des...

An environmentally friendly, facile and solvent-free synthetic route for aluminum sulfate octadecahydrate (Al2(SO4)3.18H2O) catalyzed one-pot multi-component synthesis of 12-aryltetrahydrobenzo[α]xanthene-11-ones, 1,8-dioxo-octahydroxanthenes and 14-aryl-14Hdibenzo[α,j]xanthenes has been developed. The readily, easy to handle, non-toxic, environmental friendly and low-cost catalyst, easily sepa...
