Technological Change, Depletion and the U.S. Petroleum Industry*** A common claim in the nonrenewable resource literature is that improvements in technology may largely offset the effects of increasing scarcity over time. This study provides perhaps the first empirical evidence on this issue by analyzing the determinants of the average finding cost for additional petroleum in the U.S. over the ...

Experimental autoimmune uveitis (EAU) induced in mice by immunization with the retinal Ag interphotoreceptor retinoid-binding protein (IRBP) is a model of human autoimmune uveitis. We examined whether T regulatory cells (Tregs) found in uveitic eyes are IRBP specific, functionally suppressive, and play a role in natural resolution of disease and in maintenance of remission. Progressive increase...

Current knowledge suggests that patterns of energy storage and depletion in animals are governed by behavioural trade-offs between risks associated with feeding and future energy demands. However, the length of adverse periods varies over geographical or climatic gradients. To explore the potential for genotypic sources of variation in behavioural trade-offs, we compared the winter energy-deple...

In this century man will transition to a low-carbon energy future—either in first half of the century because of concerns about global climate and ocean pH (acidity) changes or in the second half of the century because of depletion of fossil resources in a world of 10 billion people. Since the caveman discovered fire, our energy policy has been to have a storable supply of a carbon fuel (wood, ...

The depletion of non-renewable natural resources (primarily mineral and energy resources) its assessment is a problem that analyzed based on the concept sustainable development. Mineral resource particularly important for resource-based economies. It provides assessing impact asset disposal results from suspension or termination operations conducted by mining company due to insurmountable circu...

Transient regulatory T-cell (Treg) depletion with IL-2 diphtheria toxin fusion protein enhances clearance of acute myeloid leukemia by haploidentical natural killer (NK) cells Veronika Bachanova, Sarah Cooley, Todd Defor, Michael R Verneris, Bin Zhang, David McKenna, Julie Curtsinger, Angela Panoskaltsis-Mortari, Dixie Lewis, Keli Hippen, Philip McGlave, Daniel Weisdorf, Bruce R Blazar, Jeffrey...

The European Commission as well as the Polish government are promoting sustainable use of energy sources as a part of the dominating sustainable development paradigm. The development of low-emission energy sources engages the challenges of gradual depletion of coal, oil and natural gas reserves, as well as the intensification of the greenhouse effect. The energy policy should take into account ...

Li, Li, Jaladanki N. Rao, Barbara L. Bass, and JianYing Wang. NF-kB activation and susceptibility to apoptosis after polyamine depletion in intestinal epithelial cells. Am J Physiol Gastrointest Liver Physiol 280: G992–G1004, 2001.—The maintenance of intestinal mucosal integrity depends on a balance between cell renewal and cell death, including apoptosis. The natural polyamines, putrescine, sp...
