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 ...
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 ...

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 ...
Functionality of pollen and fruit set in sour cherry cultivars
(Acta Horticulturae, 1998)
During 1995 and 1996, functional ability of pollen and fruit set were examined in six sour cherry cultivars (Meteor, Rexelle, Heimanns konserven, Kelleris 14, Oblacinska sour cherry and Köröser). In both years of investigation ...
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 ...
Genetic resources of cherry plum (Prunus cerasifera ehrh.)
(Acta Horticulturae, 1998)
Investigations were carried out on 63 cherry plum genotypes collected from different autochthonous populations in Serbia. Morphological and biochemical variability of these genotypes was analyzed by multivariate analysis ...
Properties of late-ripening peach hybrids
(Acta Horticulturae, 1998)
From the progeny obtained by open-pollination of J. H. Hale cultivar, five midle late or late ripening hybrids were selected. During 1995 and 1996 important pomological properties of those hybrids were examined. Based on ...
