The middle Cretaceous Colorado Group of the Western Canadian Sedimentary Basin consists predominantly of mudstone deposited during major marine inundations interspersed with relatively thin sandstone and conglomerate beds. The Colorado Group petroleum system, containing a large portion of the light-medium oil and natural gas reserves within the Middle Jurassic to Cretaceous foreland basin succe...

in dea to obtain an efficient representation in ccr andbcc models for each dmu only one linear plan would be solved; however,it is possible in centralized resource allocation (cra) to solve allthe dmus by one linear planning. in this paper, models of centralizedresource allocation in input-oriented and in dynamic case will be offeredand by using dynamic sbm, the representation of dmus in each t...

Microbial processes are responsible for the formation, alteration, and destruction of some natural gas accumulations. Individual microbial gas accumulations may be significant (> 1 Tcf; trillion cubic feet or 28.3 billion cubic meters) and collectively account for more than 20% of the global gas resource-base, dominating in some individual basins. Often cited resource estimates do not effective...

objectives: the role of cognitive process for postural control was shown in dual task studies. however, there was no definite evidence how verbal instructions influence the allocation of attention to postural control. this study determined whether young and elderly adult are able to deliberately control the resource allocation when performing a sensorimotor and cognitive task simultaneously and...

This research aims to apply a model to the study and analysis of environmental and natural resource costs created in supply chains of goods and services produced in Thailand, and propose indicators for environmental problem management, caused by goods and services production, based on concepts of sustainable production and consumer behavior. The research showed that the highest environmental co...
