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...

The use of pheromones in the integrated pest management of insects is currently considered a sustainable and environmentally benign alternative to hazardous insecticides. 4-Methylheptan-3-ol is an interesting example of an insect pheromone, because its stereoisomers are active towards different species. All four possible stereoisomers of this compound were prepared from 4-methylhept-4-en-3-one ...

Over the past 20 years bariatric surgery proved to be a valid treatment for reduction and elimination of obesity-related diseases and long-term sustainable weight loss. Minimally invasive or laparoscopic techniques such as laparoscopic Roux-en-Y (LRNY) have replaced open procedures. Many factors play important roles in the small intricacies and variations of the procedure, chief of which is the...

Eco-Efficient stowage plans that are both competitive and sustainable have become a priority for the shipping industry. Stowage planning is NP-hard and is a challenging optimization problem in practice. We propose a new 2-phase approach that generates near-optimal stowage plans and fulfills industrial time and quality requirements. Our approach combines an integer programming model for assignin...

Cardanol is a natural and renewable organic raw material obtained as the major chemical component by vacuum distillation of cashew nut shell liquid. In this work a new sustainable procedure for producing cardanol-based micellar nanodispersions having an embedded lipophilic porphyrin itself peripherally functionalized with cardanol substituents (porphyrin-cardanol hybrid) has been described for ...

This paper provides an overview of David Selby's innovative idea of sustainable contraction, developed to counter the longstanding focus on sustainable development.

The plastic softener called DEHP, di-ethylhexyl phthalate, suddenly created life-saving flexibility for patients who could be treated safely in hospitals, at home, at work, at a trauma site, and in an ambulance. Elegant tiny catheters now could be crafted for anatomies of premature infants to provide them the breath, food, and waste removal that enabled them to survive. Trauma patients now coul...

The concept of ‘sustainability’ has become the current answer to absolving the world of its environmental and economic crises in the 21 century. Since its conceptualisation, there has been a barrage of investigations and literature on the vagueness and ambiguity of its definition and applicability. There are two main opposing schools of thought the pessimists, usually ecologists and other scien...

globally, irrigated agriculture is the largest extractor and the most frequent consumer of groundwater resources, with important groundwater-dependent and largely spread agro-economies. quality of irrigation water is one of the key factors which have either direct or indirect impact on plant growth, soil and water management practices and plant yields. this work aims at highlighting the importa...

This paper considers the development of ‘green’ jobs in Scotland where the government has sought to develop renewable and sustainable energy industries and associated employment. It analyses the government employment forecasts/projections and compares them to the actual results, considering the reasons for the lower actual job creation. While there are some specific skills development initiativ...
