water alternating gas (wag) technique is used in the petroleum industry to inject carbon dioxide (co2) into underground formations either for sequestration or enhanced oil recovery (eor) processes. co2 injection causes reactions with formation brine or aquifer and produces carbonic acid, the acid dissolves calcite and changes flow behavior significantly. modeling and investigating effects of co...

Innovation is the soul of modern enterprise, and sustainable innovation is the essential for enterprises to keep their long-term energies. Small and medium enterprises should start from the construction of interior sustainable innovation ability cultivation system, cultivate innovational leading thinking, establish innovational enterprise culture, improve innovational encouragement system, walk...

As a sustainable alternative for conventional batch-based synthetic techniques, the concept of continuous-flow processing has emerged in the synthesis of fine chemicals. Systematic tuning of the residence time, a key parameter of continuous-reaction technology, can govern the outcome of a chemical reaction by determining the reaction rate and the conversion and by influencing the product select...

There is a growing recognition that the present demographic patterns in sub-Saharan Africa, including Ghana, do not augur well for the achievement of sustainable development. Ghana is characterized by a youthful population, rapid population growth, uneven population distribution, high fertility, and rural-urban migration which has brought human numbers into collision with resources to sustain ...

Sustainability is a key challenge for humanity in the 21st century. Ecosystem services-the benefits that people derive from nature and natural capital-is a concept often used to help explain human reliance on nature and frame the decisions we make in terms of the ongoing value of nature to human wellbeing. Yet ecosystem service science has not always lived up to the promise of its potential. De...

BACKGROUND Green chemistry is a rapidly developing new field that provides us with a proactive avenue for the sustainable development of future science and technologies. Green chemistry uses highly efficient and environmentally benign synthetic protocols to deliver lifesaving medicines, accelerating lead optimization processes in drug discovery, with reduced unnecessary environmental impact. Fr...

In the contemporary period, the small and medium enterprise sector is the main vector of sustainable economic development, with a substantial weight in creating the gross domestic product and providing jobs. In this context, the paper highlights the bi-univocal relationship between the attributes of small and medium enterprises, on the one hand and the coordinates defining the modern knowledge-...

Conventional supply chain management (SCM) considered only three stages: pre-manufacture, manufacture and use, while the present enterprises and specially the small and medium sized enterprises (SMEs) need to consider the sustainable supply chain management (SSCM) for competitive and stability in the market. It means this chain have to consider from birth to death of the products or services. S...
