Mulberry genotypes were subjected to salinity (0-12 mS cm-1) in pot culture experiment. Chlorophyll and total carotenoid contents were reduced considerably by salinity. At low salinity, photosynthetic CO2 uptake increased over the control, but it decreased at higher salinity. Contents of soluble proteins, free amino acids, soluble sugars, sucrose, starch, and phenols increased at salinity of 1-2 mS cm-1 and decreased at higher salinity (8-12 mS cm-1). Glycine betaine accumulated more than proline, the maximum accumulation of both was at salinity of 2-4 mS cm-1. Among the genotypes studied, BC2-59 followed by S-30 showed better salinity tolerance than M-5. and P. Agastian, S. J. Kingsley, M. Vivekanandan.
The genital pore of the female of Intoshia variabili Аleksandrov et Sljusarev, 1992 is located on a transverse ring of non-ciliated cells. Before copulation it is occupied by 6-7 cells that develop in the epithelium and that for a time are beneath the surface. When fully developed, these cells contain many electron-dense granules and their apical surface is covered with numerous microvilli. After copulation the granules disappear and the apical surface becomes smooth. The cells still form a plug closing the opening. After one larva pushes the pore cells out and escapes, others follow.
The paper focuses on the of surface topography analysis of WPC materials (Wood Plastic Composite) after turning technology. The influence of one of the technological parameters (feed) on the character of the resulting profile is examined. The topography of the surface was evaluated by optical profilemeter MicroProf FRT. After turning, significant feeding traces are left on the surfaces, which depend on several factors, including inaccuracies affecting the result from the turning technology itself, and positioning of the sample placed on the profilemetry table. and Príspevok sa zameriava na rozbor topografie povrchu kompozitných materiálov na báze dreva (konkrétne drevom plnených plastov - Wood Plastic Composite) po technológií sústruženia. Je skúmaný vplyv jedného z technologických parametrov (posuvu) na charakter výsledného profilu. Topografia povrchu je hodnotená metódou optickej profilometrie, profilometrom MicroProf FRT. Po technológií sústruženia vzniká na povrchu materiálov výrazná stopa závislá na viacerých faktoroch, medzi ktoré je možné zahrnúť aj nepresnosti prenášané do výsledku zo samotnej technologie sústruženia a zároveň polohovania vzorky na stole profilometra.
This paper highlighs the contribution of Philipp Lenard (Nobel Prize winner 1905) to the understanding of luminescence and reviews his main results in the field. In particular, the experimental spectroscopic technique introduced by Lenard and the properties of the so-called Lenard phosphors are discussed., Ivan Pelant, Jan Valenta., and Obsahuje seznam literatury
