Commentary on Grackles Anting With Marigold Blossoms

Giannitsis: Platelet (»anting with a Laser nephelometer

Venous blood, taken with EDTA-NaCl solution according to Schulz et al (1971, Z. Klin. Chem. Klin. Biochem. 9, 329-333) is used. The blood is centrifuged at IQOg for 10 min and 10 μΐ of the supernatant is added to 3000 μΐ of a suspending medium (dilution 1:80); 300 μΐ platelet suspension are read in a nephelometer cuvet or tube against blank. The number of platelets per liter blood are determine...

Fluridone Effects on Fanwort and Water Marigold

Growth chamber studies were conducted to evaluate the effectiveness of the aquatic herbicide fluridone for control of fanwort, and to assess the impact of treatment on the nontarget plant, water marigold. Treatments included static exposures of 0, 5, 7.5, 10, 15, 20, and 30 g fluridone L. Changes in pigment concentrations within the plant (phytoene, β-carotene, and chlorophyll) and biomass were...

Shape Representations with Blossoms and Buds

Algorithms from Blossoms

Blossoming is a theoretical technique that been used to de velop new CAGD theory However once we have developed this theory we need to devise algorithms to implement it In this paper I will dis cuss converting blossoming equations into code noting techniques that can be used to develop e cient algorithms These techniques are illus trated by considering the operations of basis conversion and pol...

Dunking behaviour in Carib grackles

Dunking behaviour, the dipping of food in water, has been anecdotally observed in more than 25 species of birds in the wild, but its function and ecology have not been systematically studied. In experiments conducted in the field and in captivity on Carib grackles, Quiscalus lugubris, in Barbados, we showed that: (1) dunking rate in the field was influenced by food type and that moistening dry ...
