While it is generally known that surface heterogeneityweakens the application ofMonin–Obukhov similarity (MOS), few studies have investigated how seasonal changes in the degree of surface heterogeneity at a particular site may influence the validity of the similarity application. Exploiting seasonal changes in forest function associated with senescence, we conduct a unique evaluation of the eff...

a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...

this paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. the method considers both the spinning reserve and interruptible loads as the operating reserve services. in the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...

ba ckground: although it is widely accepted that the pre-school age is a critical period  in  the  development of  obesity,  there  are  few  published data  on  factors contributing to variation of total energy expenditure in this age group.to investigate the contribution of body composition, gender and activity on total energy expenditure (tee) in pre-school children. m ethods: the total ener...

results the modeling results showed that for the gas recovery starting in 2000 and 2015, the power generation would be 2,354 and 830 mw, respectively. in fact, the 15-year difference in gas extraction made a 200% difference. based on the results, from 2000 to 2100, 558 m3/hour of methane would be extracted, which would be equivalent to 2,354 mw energy. subsequently, the emission of 93,721,837 t...

the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

the our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in alborz province in the year of 1391-92. it was a best way that we use po...

background & aim: energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. if one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. in addition to the net income of the farmers, this issue would play a ...
