However, systematic collecting did not begin until the 1950s. Collections of animal sound recordings serve many uses in education, entertainment, science and nature conservation. In recent(More)
BACKGROUND Despite the ecological and agricultural significance of bumble bees in Alaska, very little is known and published about this important group at the regional level. The objectives of this study were to provide baseline data on species composition, distribution, seasonal biology, and parasites of the genus Bombus at three major agricultural(More)
The use of triclopyr for the removal of woody and broad-leaf vegetation in right-of-ways and agricultural settings has been proposed for Alaska. Triclopyr concentrations in soil after application are of concern because residual herbicide may affect growth of subsequent vegetation. In order to measure triclopyr residues in soil and determine the amount of(More)
374 patients with florid chronic pyelonephritis were examined concerning the frequency of a funguria. In primary diseases in 7.8% and in secondary forms in 12.4% of the cases fungi could be proved in the urine. Furthermore it is reported on course and therapy of manifest infections with fungi.
Manifest infections with fungi of the urinary tract are rare in comparison with bacterial diseases and therefore they are often overseen. When this is concerned a funguria must always be clarified in chronic pyelonephritis. In patients with manifest infections with fungi without pronounced renal insufficiency 5-fluorocytosin is therapeutically very well(More)
The transrectal ultrasonography is suited to image the prostate like no other imaging procedure. In a palpatory suspicious prostate with an ultrasonographical echo-poor area a prostatic cancer should be suspected whereas this area in a palpatory normal prostate point to inflammatory changes. In the presence of echo-dense areas or a homogenous external gland(More)
The good results on dogs, particularly in the patch substitute group, show that the Tunica vaginalis-periorchium-substitution of defects of the urethra fulfils all the expectations wanted. From this we conclude the right to recommend the broader use of this method in man.
