Throughout most of the late 19 th and early 20 th centuries the US was the world's foremost oil producing and exporting nation; it was also the first important producing nation to pass its all-time oil production peak, which occurred in 1971. The impacts on the US of its own oil peak for the nation's economy and foreign policy are rarely discussed in that country, but they have been considerabl...

Oil is a major source of income for Ecuador and since the 1970s has been the " engine " of the nation's economy. Before the 1970s oil price boom, Ecuador was one of the poorest countries in Latin America. Since then, oil production has been the primary cause of Ecuador's economic growth, which has averaged 7% annually. Per capita income rose from US$ 290 in 1972 to US$ 1 200 in 2000. Today, oil...

It has been known for several years that stimulus-evoked metabolic activity is reduced in the somatosensory cortex of animals with basal forebrain lesions that deplete the neocortex of acetylcholine (ACh). During 2-deoxyglucose (2-DG) experiments, animals with unilateral basal forebrain lesions demonstrate a decreased response to somatic stimulation, while background metabolic activity in the s...

Recordings were made from neurons in layers II, III, and IV of rat barrel cortex. The animals were raised either from the day of birth (P0) or from P2, P4, or P7 with just the D1 vibrissa protruding on one side of the face and the contralateral side intact. Follicles were not ablated, but vibrissae were carefully removed by applying steady tension to the base of each vibrissa. Deprivation was c...

The influence of the addition oak chips and barrel ageing on basic wine parameters volatile compounds Chardonnay wines has been studied. were obtained by traditional wine-making process. Oak (4 g/L—non-toasted light toasted) added at final stage winemaking process for 1, 2 3 months, respectively. Also, control was aged in non-toasted barrels same period time. Following Liquid-liquid extraction-...

In light of a previous report suggesting that the brains of tenascin-deficient animals are grossly normal, we have studied the somatosensory cortical barrel field and injured cerebral cortex in postnatal homozygous tenascin knockout, heterozygote, and normal wild-type mice. Nissl staining, cytochrome oxidase, and Dil axonal tracing of thalamocortical axonal projections to the somatosensory cort...
