چکیده
23 strains of rhizobia, from 14 leguminous species, were evaluated on a Thai cultivar of Voandzeia* in Leonard jar trials. The symbiosis ranged from completely ineffective through moderate effectiveness to fully effective. Bradyrhizobium sp. TAL 169, isolated from Vigna unguiculata, ranked most-effective; the widespectrum Bradyrhizobium strain CB 756 was ineffective. In a cultivar x Bradyrhizobium spp. trial, the host-genotype significantly (P _ 0.01 or P 0.001) influenced shoot dry weight, shoot N, nodule dry weight and nitrogenase activity. The rhizobial strains were also significant sources of variation for shoot-dry weight (P = 0.05), shoot N (P < 0.001) and nodule dry weight (P < 0.01). There were no significant host x Rhizobium interactions, indicating that no specific combination was superior over the broad range of all treatments. Percentage shoot N and specific nitrogenase activity were poor indicators of N2 fixation capacity in Voandzeia. Voandzeia cultivar No. 12 P.P. Rust in combination with Bradyrhizobium sp. TAL 169 showed high potential for growth, nodulation and N2 fixation. This study indicated that Voandzeia is specific for its rhizobial requirement for effective symbiosis.

NOM Rejection by, and Fouling of, NF and UF Membranes
OBJECTIVES: The performance of spiral-wound nanofiltration (NF) and ultrafiltration (UF) membranes was investigated in terms of natural organic matter (NOM) rejection and associated NOM fouling. The study objectives focused on • demonstrating the effects of both hydrophobic and electrostatic interactions between NOM components and the membrane surface • determining influential factors (water qu...
متن کاملReplacement names and nomenclatural comments for problematic species-group names in Europe's Neogene freshwater Gastropoda. Part 2
In the course of a new database project on Miocene to Recent freshwater gastropods of Europe, a great many of primary and secondary homonyms were revealed. Such nomenclatural issues need clarification in order to avoid misunderstandings and wrong statements about geographical distributions and temporal ranges. The following 16 new names are introduced to replace existing homonyms: Theodoxus mil...

We synthesize data on all known extant and fossil Coleoptera family-group names for the first time. A catalogue of 4887 family-group names (124 fossil, 4763 extant) based on 4707 distinct genera in Coleoptera is given. A total of 4492 names are available, 183 of which are permanently invalid because they are based on a preoccupied or a suppressed type genus. Names are listed in a classification...
