Relative photonic efficiencies and quantum yields in heterogeneous photocatalysis

Journal of Photochemistry and Photobiology A: Chemistry, 1997
AbstractQuantum yield and quantum efficiency (QY) as used in heterogeneous photocatalysis (solid/liquid or solid/gas systems) have too often been used incorrectly to mean the ratio of the rate of a given event to the rate of incident photons impinging on the (external) reactor walls, typicallyfor broadband radiation.

Yield - Efficiency Indicator Production Products

2019
The article presents a mathematical relationship between cost, profit and yield, presents a mechanism for the relationship of yield and the cost of grape production. The dependence of the yield of profit per unit of area and unit of production on the level of yield is shown; a formula for calculating marginal profit per unit of production depending on ...

Fungicides efficiency on alfalfa seed yield

1998
Lucerna je najzastupljenija krmna kultura na oranicama u Republici Hrvatskoj.Potrebe sjemena procjenjuju se na 250-300 t godišnje.Pored relativno povoljnih agroekoloških uvjeta za proizvodnju sjemena te velikog broja domaćih priznatih kultivara, vlastita proizvodnja je nedostatna, i više od 70 % potreba podmiruje se uvozom.U Osijeku su tijekom 1994.
