Fossil Shells from The Hachimori Oilfield, Akita Pref.

The total amino acid content of fossil pecten shells.

Amino acid analyses have been made of the insoluble protein, soluble peptide, and free amino acid fractions isolated from a series of fossil pecten shells of ages from the Pleistocene through the Jurassic. The total amino acid content declines progressively with age of the fossil but, in contrast to oyster shells, only a small fraction of the initial protein is present in the Pleistocene and ol...

The Akita and hypothyroidism

Hypothyroidism is a condition in which there are low concentrations of thyroid hormones in the blood. It is one of the most common hormonal disorders in dogs, but rare in cats. Thyroid hormone is important for the normal regulation of metabolic rate and activity in many tissues and a deficiency of the hormone results in reduced metabolic activity and abnormal changes in many organ systems. If p...

Delineating modern variation from extinct morphology in the fossil record using shells of the Eastern Box Turtle (Terrapene carolina)

Characterization of morphological variation in the shells of extant Eastern Box Turtles, Terrapene carolina, provides a baseline for comparison to fossil populations. It also provides an example of the difficulties inherent to recognizing intraspecific diversity in the fossil record. The degree to which variation in fossils of T. carolina can be accommodated by extant variation in the species h...

Greenhouse gas emissions from oilfield-produced water in Shengli Oilfield, Eastern China.

Greenhouse gas (GHG) emissions from oil and gas systems are an important component of the GHG emission inventory. To assess the carbon emissions from oilfield-produced water under atmospheric conditions correctly, in situ detection and simulation experiments were developed to study the natural release of GHG into the atmosphere in the Shengli Oilfield, the second largest oilfield in China. The ...
