Any system intending to improve the environmental performances of a process should be assessed by Life Cycle Assessment. This work draws up profile heat provided storage recovering industrial waste at high temperature (500 °C) through 5 selected indicators: Cumulative Energy Demand, Global Warming Potential, abiotic depletion potential, particle matter and freshwater eutrophication. The calcula...

Seven companies were studied with the purpose to discuss learning in production with regardto actual potential and course of action to realize the potential. The study shows thatcompanies that focus on learning in production can reach significant improvements despitelow input of resources with a payback time of often less than a year.

Heat recovery ventilation systems, because of reducing ventilation loss through recovered exhaust air, can play a good role in the effectiveness of ventilation to reduce energy use. In this paper, the impact of a heat recovery ventilator (HRV) on the energy use and indoor radon in residential buildings is investigated. This paper describes the effects of a heat recovery ventilation system on en...

Greenhouse gas emission trading programs have been initiated in the European Union, Canada and the United States in an effort to harness market forces to efficiently reduce greenhouse gas emissions. Three major methods for reducing or offsetting greenhouse gas emissions are purchasing greenhouse gas emission reduction credits, purchasing renewable energy certificates, and improving energy effic...

Case Study Feasibility Analysis of Renewable Energy Supply Systems in a Small Grid Connected Resort By Jody Robins Dr. Robert Woods, Committee Chair Professor of Hotel Management University of Nevada, Las Vegas This paper presents a case study on the feasibility of a small grid connected resort in the marine west coast climate of Canada to implement a renewable energy supply system. The current...

BACKGROUND It is known that parents have lower mortality than childless individuals. Support from adult children to ageing parents may be of importance for parental health and longevity. The aim of this study was to estimate the association between having a child and the risk of death, and to examine whether the association increased at older ages when health starts to deteriorate and the need ...

In this study, the combined effects of light and water availability on the functional relationships of the relative growth rate (RGR), leaf chemical composition, construction and maintenance costs, and benefits in terms of payback time for Coffea arabica are presented. Coffee plants were grown for 8 months in 100% or 15% full sunlight and then a four-month water shortage was implemented. Plants...
