New invasive species of aphids (hemiptera, aphididae) in Serbia and Montenegro
(Srpsko biološko društvo, Beograd, i dr., 2010)
Three new invasive species of aphids have been found in Serbia: Chaitophorus populifolli Essig, Myzocallis walshii (Monell) and Trichosiphonaphis polygonifoliae (Shinji) and two have been found in Montenegro: Aphis ...
Restructuring of the Hungarian electricity industry
(Carfax Publishing, Basingstoke, 2001)
Restructuring the monopolistic, state-owned, obsolete and polluting utility industries of post-socialist economies poses a challenge for the utility deregulation wave travelling around the world. Utility restructuring in ...
The productive traits of different potato genotypes in mountainous region of Montenegro / Produktivne osobine različitih genotipova krompira u planinskom regionu Crne Gore
(Društvo genetičara Srbije, Beograd, 2012)
The results of three-year study of productivity for the five leading potato varieties in Montenegro: Riviera and Tresor (early), Kennebec (medium-early), Aladin and Agria (medium-late) are presented. The research was ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Srpsko hemijsko društvo, Beograd, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Edizioni Minerva Medica, Turin, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
Potentiometric titration of pralidoxime chloride (2-pyridinealdoxime methochloride) with a silver indicator electrode
(Journal of Analytical Chemistry, 1998)
It is shown that a silver indicator electrode can be used in the potentiometric titration of pralidoxime chloride [2-pyridinealdoxime methochloride (PAM-2)] with palladium(II) chloride and silver nitrate solutions. The ...
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 ...
A case of monstra duplicia in Tetranychus urticaekoch (Acari: Tetranychidae)
(Acarologia, 2000)
A case of monstra duplicia is recorded in a laboratory population of Tetranychus urticae Koch. The population had not been previously exposed to teratogenic agents. The developmental abnormality was found in the protonymph ...
Protein degradability of some concentrate feeds used in dairy cow nutrition
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 1999)
Protein degradibility in concentrates and by-products commonly used was determined by the in situ method on two ruminally cannulated lactating cows. The investigated feeds and their effective protein degradability at a ...
