The effects of selenium application on replant soil and its content in apple leaves and fruits
(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 ...
Antimicrobial activity of essential oil of Carlina acaulis L., Asteraceae
(Pharmaceutical and Pharmacological Letters, 1998)
Diffusion techniques on Mueller - Hinton agar as well as dilution technique in Mueller - Hinton broth were applied to test sensitivity of certain bacteria to Carlina acaulis L. root essential oil. Saburaud base was used ...

Fire blight of pear, caused by Erwinia amylovora (Burr.) Winslow, et al., is one of the oldest and the most destructive disease caused by bacteria on pome fruits. This disease is most dangerous on pear (Pyrus sp.), making ...
The content of selenium in raspberry plant and its improvement by SE - Fertilization
(Acta Horticulturae, 1998)
The experiment with the use of selenium fertilizer (sodium selenate) on low SE brown-forest soil (183 μg/kg) was conducted with red raspberry (Rubus idaeus) under field conditions. Selenium was added in the following doses: ...
Monoterpenoids from Helminthia echoides
(Fitoterapia, 1998)
Coupled vertical mast (monopole) antennas in the presence of a conducting half-space
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 1998)
The unknown current distribution (UCD), self and mutual admittances (impedances), grounding impedances of coupled vertical mast antennas (CVMA) on a conducting halfspace are presented in this paper. The UCD is determined ...
The biodegradation of wheat straw by Pleurotus ostreatus mushrooms and its use in cattle feeding
(Elsevier, Amsterdam, 1998)
The influence of Pleurotus ostreatus enzymes on wheat straw degradation was investigated in laboratory conditions. Chopped and pressure-pasteurized straw with 24% dry matter was seeded with mushroom mycelium. Analyses of ...
