Stone and his co-workers * have reported recently on certain unusual pharmacological properties of mecamylamine (3-methylaminoisocamphane) hydrochloride. This compound, a secondary amine, produces a marked and prolonged degree of blood pressure reduction and ganglionic blockade in animals. Blecamylamine also is well absorbed from the gastrointestinal tract, the L. D.so being approximately the s...

Objectives: Efforts are made in radiographic examinations to obtain the best image quality with the lowest possible absorbed dose to the patient. In dental radiography, the absorbed dose to patients is very low, but exposures are relatively frequent. It has been suggested that frequent low-dose exposures can pose a risk for development of future cancer. It has previously been reported that ther...

Radiolabeled exendin is used for non-invasive quantification of beta cells in the islets of Langerhans in vivo. High accumulation of radiolabeled exendin in the islets raised concerns about possible radiation-induced damage to these islets in man. In this work, islet absorbed doses resulting from exendin-imaging were calculated by combining whole organ dosimetry with small scale dosimetry for t...

Aluminium alloy 6061 is known for its superior mechanical characteristics, which include lighter weight properties, high specific strength,and simple fabrication. Hence, they are widely used to reduce the of vehicles as structural parts. issubjected velocity and various forces in courseofan accident. understanding impact properties aluminium alloys critical.

Jupiter has half a dozen eastward jet streams in each hemisphere. On average, Earth has only one in each hemisphere. Jupiter has weather patterns ("storms'') that last for centuries. Earth has stationary weather patterns fixed to the topography, but the average lifetime of a traveling storm is rvl week. Jupiter has no topography, i.e. , no cont inents or oceans; its atmosphere merges smoothly w...
