Abstract Multiple international stakeholders emphasise the important role of small- to medium-sized enterprises (SMEs) in achieving sustainable development goals (SDG). SMEs make up more than 99% companies Europe, and holds a potential promote social environmental responsibility. However, there is no ‘one size fits all’ when it comes incorporation SDGs. In this study; we identify five main appr...

The analysis of ventilation strategies is fundamentally affected by regional climate conditions and local cost databases, in terms energy consumption, CO2 emission cost-effective analysis. A systematic approach covered this paper to estimate a economic environmental impact on medium-sized space located two regions during supply-and-installation operation phases. Three strategies, including mixi...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

Enantioselective catalytic allylic alkylation for the synthesis of 2-alkyl-2-allylcycloalkanones and 3,3-disubstituted pyrrolidinones, piperidinones and piperazinones has been previously reported by our laboratory. The efficient construction of chiral all-carbon quaternary centers by allylic alkylation was previously achieved with a catalyst derived in situ from zero valent palladium sources an...

In atmospheric chemistry, interactions between air pollution, the biosphere and human health, often through reaction mixtures from both natural and anthropogenic sources, are of growing interest. Massive pollution emissions in the Anthropocene have transformed atmospheric composition to the extent that biogeochemical cycles, air quality and climate have changed globally and partly profoundly. I...

Bye bye palladium. Kai A. I. Zhang and coworkers develope a palladium-free and photocatalytic Stille-type coupling reaction of aryl iodides and aryl stannanes by a conjugated micro porous polymer-based photocatalyst under visible light irradiation at room temperature in article number 1700101. Via the aryl radical-mediated reaction pathway, the light-promoted coupling reaction using a pure orga...

AIM The aim of this study was to explore nurses' perceptions of climate and environmental issues and examine how nurses perceive their role in contributing to the process of sustainable development. BACKGROUND Climate change and its implications for human health represent an increasingly important issue for the healthcare sector. According to the International Council of Nurses Code of Ethics...

Not yet two decades after the publication of Our Common Future, the world’s political and environmental landscape has changed significantly. Nonetheless, we argue that the concept and practice of sustainable development (SD)–as guiding institutional principle, as concrete policy goal, and as focus of political struggle–remains salient in confronting the multiple challenges of this new global or...

The Fourth World Conference on Women acknowledged that environmental degradation 1) disproportionately affects poor women who are powerless to control it, 2) is linked to poverty, and 3) jeopardizes women's reproductive health. Thus, the Platform for Action addresses environmental inequalities among its 12 areas of critical concern, and the governments who signed the consensus agreed to take a...
