The solution to this urgent problem is the use raw material in construction industry, which would solve many economic and environmental problems. article describes main technologies residential houses from wood concrete blocks features operation such buildings. Methods comparative analysis structure ...
Environmentally friendly synthetic methodologies have gradually been implemented as viable techniques in the synthesis of a range of nanostructures. In this work, we focus on the application of green-chemistry principles to the synthesis of complex metal oxide and fluoride nanostructures. In particular, we describe advances in the use of the molten-salt synthetic methods, hydrothermal protocols...
The purpose of this study was to evaluate the physical and mechanical properties of environmentally-friendly films for fresh-cut lettuce. This objective was achieved by determining the gas transmission rates for oxygen, water vapor, carbon dioxide, and the thermal and mechanical properties of the films following ASTM standards D3985, F1249, F2476-05, D3418-03, and D882-02, respectively. Electro...
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...
