Data from six experiments (two with dry cows) were used to predict partitioning of gross energy to CH4 in Holstein cows using selected independent variables, some of which were intercorrelated, and a stepwise backward elimination regression procedure. Methane outputs ranged from 3.1 to 8.3% (mean 5.5) of gross energy intake for 134 dry cow balance trials and from 1.7 to 14.9% (mean 5.2) of gros...

Stool energy losses and the sources of energy within the stool were determined in 20 healthy controls and 20 patients with cystic fibrosis while on their habitual pancreatic enzyme replacement treatment. Stool energy losses were equivalent to 3.5% of gross energy intake in healthy children (range 1.3-5.8%). Despite a comparable gross energy intake, stool energy losses were three times greater i...

In assessing the nutritional status of populations, it is becoming increasingly common to measure not only the total food intake but also the energy expenditure of groups of individuals. I t is often difficult to compare the results obtained by different authors in such studies of energy expenditure because of the diverse ways in which these results may be expressed. The metabolic cost of a per...

the aims of this study were to assess the energy and economic flows of biodiesel production from olive pomace oil using transesterification method with ultrasound waves. for this purpose biodiesel production from this feedstock were examined through a life-cycle process with considering five main stages of agricultural production, transportation, olive oil extraction, pomace oil extraction and ...

This work is aimed at calculating the energy content of the residues from olive oil production. Olive pulp, olive husk and sludge (a mixture of olive pulp and husk) have been analyzed separately. Olive Mill Effluents (OME) are normally a problem for olive mill farms, yet they may be used as feedstock for biomass-fuelled power plants. Nonetheless, OMEs are characterized by a relatively high humi...

The gross energy cost of treadmill and track running is re-investigated from data published in the literature. An average equation, weighted for the number of subjects in each study, was found: VO2 (ml/kg/min) = 2.209 + 3.163 speed (km/h) for 130 subjects (trained and untrained males and females) and 10 treadmill studies. On the track, wind resistance as predicted by Pugh (1970) was added to th...

it can be argued that fuel and energy sector plays a crucial part in the countries' development and improvement of people's living standards, constituting a pillar of economic development for nations. electricity is considered as an infrastructure for economic, social and cultural development in a way that the growth in electric power is evaluated as an indicator for measuring the gro...

in this paper, the energy demand of transport sector from 1385 to 1400 is forecasted based on fuzzy linear regression (flr) approach considering economic and social indicators. in order to analyze the influence of economic and social indicators on energy demand of transport sector, gross domestic product (gdp), population and the total number of vehicles in 1372-1384 were regarded. in this rese...
