Photo-selective nets and potassium concentrations on Costus lasius crop

Modification of Sunlight Radiation through Colored Photo-Selective Nets Affects Anthocyanin Profile in Vaccinium spp. Berries

OBJECTIVES In recent years, the interest on the effects of the specific wavelengths of the light spectrum on growth and metabolism of plants has been increasing markedly. The present study covers the effect of modified sunlight conditions on the accumulation of anthocyanin pigments in two Vaccinium species: the European wild bilberry (V. myrtillus L.) and the cultivated highbush blueberry (V. c...

Aesthetic photo composition by optimal crop-and-warp

We present a high-efficiency approach to optimally enhance image composition using a crop-andwarp-based algorithm. We have designed a piecewise quadratic aesthetic energy function with linear inequality constraints that measures the distance between original positions and the aesthetic target positions of visual elements, to assess the target image composition. The target image is cropped by a ...

Crop Potassium Nutrition – Implications for Fertilizer Recommendations

Correlations of Crop Load and Return Bloom with Root and Shoot Concentrations of Potassium, Nitrogen, and Nonstructural Carbohydrates in Pecan

The current theory of pecan [Carya illinoinensis (Wangenh.) C. Koch] alternate bearing is the ‘‘growth regulator–carbohydrate theory’’ in which flowering is first controlled by growth regulators produced by fruit and leaves, and then by the size of the carbohydrate pool near budbreak. Lack of nitrogen (N) reserves has also been proposed to be limiting after large crops, thus reducing return blo...

Potassium concentrations in irradiated blood.

Blood components are irradiated to reduce the risk of graft versus host disease induced by transfusion in a wide range of immunocompromised patients. Irradiation has been claimed to be harmless to red cells and neutrophil function and to have little effect on platelet increments.'`3 A case of fatal graft versus host disease induced by transfusion in a child prompted our paediatric oncologists t...
