Rhizobiumsymbiotic bacteriaInfluence of ascending nitrogen supply on the development of Rhizobium symbiotic bacteria on peas (Pisum sativum L. ssp. sativum) in nutritive culture solutionThe effect of ascending N-supply with 4 different levels from 0.1 to 1.56 mg atom/L culture solution on juncture,...
The future market penetration of hydrogen vehicles into the total fleet will also depend on the fact that hydrogen can achieve a tax exemption or relief for a certain time period.%Die Vielfalt auf den Straßen nimmt zu. Immer mehr Fahrzeuge, die nicht Benzin oder Diesel sondern Wasserstoff ...

Aluminium liegt im Boden in verschiedenen Fraktionen vor. Der Gesamtaluminiumgehalt kann in Böden bis zu 10 Gew.-% erreichen, amorphes Aluminium bis zu 2 Gew.-%. Die Mobilität von Aluminium hängt in erster Linie vom pH-Wert des Bodens ab. Im pH-Bereich von 5-8 liegt Aluminium ...
The crystal structure of the Cu complex [CuL 2 ]Cl 2 exhibited a chain structure with a five-coordinate Cu II centre in which two amino groups of the triamine ligands are coordinated to one Cu centre, while the third amino group of one of the ligands is bonded to a neighbouring Cu ...
The rate and the kinetic data of the heterogeneous exchange reactions are compared with that of the homogeneous reactions. The conclusions to be drawn for the electrochemical adsorption reactions are discussed.doi:10.1002/bbpc.19690730511J. W. Schultze...

Local differences in the population density of Spruce Lachnidae being induced, partially, by fertilizers, were compensated and even "over-compensated" by a density governing action of predators. This demonstrates that the influence of fertilizers on forest insects can not be evaluated reliably except...
The experimental techniques used were rotating disc electrodes and corrosion tests with segmented tube as a corrosion sample. The results obtained indicate that the products tested indeed reduce the rate of corrosion of different materials, this due to partly interfering with the mass transfer of ...
