Studies on the cholesterol ester hydrolase of Trogoderma (Coleoptera).
The enzyme cholesterol ester hydrolase (EC 3.1.1.13) was detected in the larvae of the khapra beetle, Trogoderma granarium (Everts). The pH and temperature optima for the enzyme were 6.6 degrees and 37 degrees C respectively. The mol.wt. of the enzyme was 76000-80000. The enzyme was equally effective in hydrolysing cholesteryl acetate, stearate and oleate. Cholesterol derivatives, namely the ch...
متن کاملon semihypergroups and hypergroups
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
15 صفحه اولcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولSieve Plates and Habitat Adaptation in the Foraminifer Planulina ornata
Planulina ornata (d'Orbigny), a coarsely perforate species of foraminifera having a low trochospiral test, was recovered attached to phosphatic hardgrounds from the lower oxygen-minimum zone off Peru. Above the base of individual pores are calcified, perforate sieve plates, the largest so far described. Structure of the pores suggests a possible association with mitochondria and respiratory fun...
متن کاملBehavior, Parasitism, Morphology, and Biochemistry of Criconemella xenoplax and C. ornata on Peach.
Host-parasite relationships of Criconemella xenoplax and C. ornata on Nemaguard peach and common bermudagrass were determined in the greenhouse. Criconemella xenoplax reproduced on peach and reduced root volume, height, and dry stem weight after 6 months, compared with the noninfested check. Numbers of C. ornata did not increase on peach or influence peach growth, but they did reduce dry top we...
