Painting of hives and marks near the entrance to reduce drifting


, : Painting of hives and marks near the entrance to reduce drifting. Pchelovodstvo ( 8): 7-8

When 28 or 48 nucleus hives were piled up in a block, queen losses were 25% and 50%, respectively. Colour differentiation tests were made with coloured entrances (a 10 x 10 cm plate against a black hive front); after training a nucleus colony to a particular colour, it was given a choice of this colour and another. Bees did not distinguish between some colour pairs (e.g. blue and white).

Levansucrase, a Bacillus subtilis extracellular enzyme, was not secreted in the culture medium when produced in yeast. The protein accumulated inside the cell in its precursor form which represented 0.3% of total proteins. The absence of any post-...

Pax-5 gene is important transcription factor in B-lymphopoiesis and B-cell development. To understand the regulatory mechanism of pax-5 expression, the immediate 5'-flanking region (6 671 bp) of human pax-gene exon 1B was isolated and charact...

Recent bacteriological data concerning pyelonephritis mainly focus on sensitivity to antibiotics and virulence factors. Epidemiologically, and regardless of age and sex of the patients, E. coli remains the most often isolated pathogen. Only 55% of...

As a result of multicenterical retrospective study on the oral cavity carcinoma we can conclude: 1. The size of the primary tumour is a prognostically relevant factor. 2. The T-classification of UICC 1978 is unsuitable to form prognostically homog...
