Recordings of wild animals were first made in the Palearctic in 1900, in the Nearctic in 1929, in Antarctica in 1934, in Asia in 1937, and in the Neotropics in the 1940s. 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)
This work reports on the use of cultural practices that influence grasshoppers' nymphal emergence. Grasshopper eggs were buried at depths of 2, 14, 18, 22, and 26 cm in laboratory arenas. Nymph eclosion ranged from 77.5 to 87.8%. However, nymph emergence, measured as the number of nymphs that reached the soil surface, was estimated at 70.9% when eggs were(More)
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)
Since 1981 a curative radiation treatment was performed in 84 patients with prostatic carcinoma. Previously, in 37 cases a transurethral resection of bladder outlet obstruction was done and in 18 patients a pelvic lymph node dissection was performed, whereas 29 patients were without operative therapy. Mild side effects of radiation could observed in all 3(More)
From June 1984 to December 1986 twenty-one benign ureteral stenoses were treated. After percutaneous nephropyelostomy an antegrade dilatation was performed by means of balloon catheters or increasing size of angiographic catheters. Subsequently an ureteral splinting with a F-12-catheter and a glucocorticoid therapy was followed. 13 strictures (61.9%) were(More)

From this short description of the course of our experiments it becomes evident to every experimentator which diverse technical problems had to be mastered to get evaluable preparations. After extensive preliminary we are able since the beginning of this year to carry out the systematic elaboration of the entire bioptic material. On account of the long(More)
During almost 3 years in 100 patients the percutaneous nephropyelostomy was used as method of the supravesical discharge of urine 109 times. The X-ray-aimed puncture was performed on the basis of the fine needle puncture technique by means of a puncture set which we developed ourselves. When a urinary retention is present, the number of targets is great(More)
