Abstract A wide variety of cutting fluids are commercially available in the cutting fluid suppliers in order to provide machining performances for a number of industries. In machining, mineral, synthetic and semi-synthetic cutting fluids are widely used but, recently, uses of vegetable based cutting fluids have been increased. Although, these cutting fluids are beneficial in the industries, the...

This paper proposes an optimal selection method to address the real-world problem of environmentally friendly supplier selection, based on prospect theory. This study adopted the manufacturer’s point of view, and considered the manufacturer’s psychological and behavioral factors in the process of choosing suppliers. The first step was to build supplier-selection indexes for manufacturers. Then,...

Focus of the leather producing industry is the transformation of untreated skins that are brittle under dry conditions and may rot under wet conditions into durable, imperishable leather by processes which incorporate tanning agents into the hides. The traditional processes comprise a multitude of different steps (up to 70), are time-consuming and water intensive. An accrual of 20 to 40 t of wa...

We discuss an environmentally friendly renormalization group approach to analyze phase transitions. We intend to apply this method to the Electroweak Phase Transition. This work is in progress. We present some previously obtained results concerning a λφ 4 theory, where the main features of this algorithm are introduced.

In 1995, Praxair Surface Technologies, Inc., and Surface Solutions, Inc., partnered to develop, test, and evaluate a promising, but experimental, coating technology invented by Surface Solutions. Early work with Surface Solutions' linear magnetron sputtering (LMS) process indicated that it had the potential to apply uniform, high-quality ceramic coatings to the internal surfaces of steel cylind...

This paper identifies which information about tourists serves as the best predictor of their pro-environmental behavior at home and on vacation. If a small set of predictors can be identified, the tourism industry would be able to use them to focus attention on attracting tourists with smaller environmental footprints. Results from a survey asking respondents about pro-environmental behavior in...

In 1994, Darryl Diefes, DDS, a Whiteville, NC, dentist was troubled. The local newspaper reported on dangerous mercury levels in fish in nearby Lake Waccamaw, a popular fishing spot. Dr. Diefes began to worry about the source of the mercury. “I knew I handled a lot of mercury in my office and I wanted to know if I was somehow contributing to the problem,” Dr. Diefes explains. That report marked...

Primary explosives are used in small quantities to generate a detonation wave when subjected to a flame, heat, impact, electric spark, or friction. Detonation of the primary explosive initiates the secondary booster or main-charge explosive or propellant. Long-term use of lead azide and lead styphnate as primary explosives has resulted in lead contamination at artillery and firing ranges and be...

an efficient, mild and environmentally friendly method was reported for the synthesis of an efficient, mild and environmentally friendly method was reported for the synthesis of pyranopyroles from aryl aldehydes, ethyl acetoacetate, malononitrile and hydrazine hydrate in the presence of catalytic amounts of methyl imidazolium hydrogen sulfate ([hmim][hso4]) as an efficient catalyst. these synth...
