The efficient capture and storage of gaseous CO(2) is a pressing environmental problem. Although porous metal-organic frameworks (MOFs) have been shown to be very effective at adsorbing CO(2) selectively by dint of dipole-quadruple interactions and/or ligation to open metal sites, the gas is not usually trapped covalently. Furthermore, the vast majority of these MOFs are fabricated from nonrene...

Increased prices for nonrenewable heating fuels (such as propane, heating oil, and natural gas) have residential and farm consumers seeking more sustainable solutions to their heating needs. Price increases among these fuels will remain a trend as a combination of decreased reserves and increased demand continues to limit supply (EIA, 2012). Pellets produced from abundant biomass sources—such a...

The concept that, after developmental periods, neocortical neurons become numerically stable and are normally nonrenewable has been challenged by a report of continuous neurogenesis in the association areas of the cerebral cortex in the adult Macaque monkey. Therefore, we have reexamined this issue in two different Macaque species using the thymidine analog bromodeoxyuridine (BrdU) as an indica...

Standard endogenous growth models rely on the arbitrary assumption that the technology has exactly constant returns with respect to producible inputs. Can this knifeedge restriction be relaxed by including non-renewable resources as necessary inputs in production? In a one-sector optimal growth model, we find that the strain on the economy imposed by the need to extract successively smaller amo...

Accurate and sufficient information on unit emergy values (UEVs) is very fundamental for emergy calculations and is also essential for the broad acceptance, application and further development of the emergy method. As an extension of matrix methods, an input-output model based framework was built in this paper, for estimating transformity (UEV) of products and services of a certain economy. The...

The completion time and nonrenewable resources are traditionally considered for construction of project. When renewable resources, quality and some criteria considered for the project, the risk related to criteria has to be taken into account. Thus project planning problem can be defined as multicriteria decision problem under risk. In this paper, a project scheduling problem including time, co...
