(Acta Horticulturae, 1998)
In the field experiment, with apple Jonagold variety, the effect of different ways of selenium application on replant soil was examined. The investigated orchard was planted on a brown forest soil with very low Se content ...
Functional enzymes activity and gill histology of carp after copper sulfate exposure and recovery
(Academic Press Inc Elsevier Science, San Diego, 1998)
Copper sulfate is one of the most widely used algicides for the control of phytoplankton in lakes, reservoirs, and ponds. It is also used for aquatic weed control. To study the toxic effects of copper on carp (Cyprinus ...
Comparison of binary gas mixture separations in single-membrane and two-membrane cascades
(Hungarian Journal of Industrial Chemistry, 1998)
The objective of this paper is to develop material balances, equilibrium, and transport equations for a binary gas mixture separation in the single-membrane and two-membrane cascades, and to compare their performances. An ...

Binary gas mixture separation in dual, permeators with permeate recycles
(Hungarian Journal of Industrial Chemistry, 1998)
Mathematical models of perfectly mixed dual permeators with permeate recycles, operating with zero reject flow rate and zero permeate pressures (gamma' = gamma " = 0), have been developed. The equations for determination ...
Observations on spear replacement in Xiphinema dentatum (Nematoda : Longidoridae)
(Brill Academic Publishers, Leiden, 1998)
The process of spear (odontostyle + odontophore) replacement was determined by studying juveniles of Xiphinema dentatum in different phases of moulting. The process is subdivided into eight distinct phases, each readily ...
