the influence of different initial inoculum densities of the root-knot nematode meloidogyne javanica on the growth of sage (salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. with the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...
Due to a preoccupation with periods of large-scale social change, nationalism research had long neglected everyday nationhood in contemporary democracies. Recent scholarship, however, has begun to shift the focus of this scholarly field toward the study of nationalism not only as a political project but also as a cognitive, affective, and discursive category deployed in daily practice. Integrat...
Using state-level data from the United States, we find that initial legal systems in territories originally settled by Great Britain – a common law country – and in territories originally settled by France, Spain, and Mexico and the Netherlands all civil law countries have persistent effects on the quality of contemporary institutions. In order to explain these findings, we develop a transplant...
this paper is a preliminary communication of a study on removal and recovery of heavy metalsfrom industrial waste waters using electro-coagulation (ec) technique. the larger study envisages use of solarenergy for producing the d.c. current, and simple chemical methods of standard methods in chemistry like useof hydrochloric acid, hydrogen sulfide, collection of precipitate, incineration and get...
Spatial and temporal variability in distribution and growth of newly settled red drum Sciaenops ocellatus were examined in the Aransas Estuary, Texas, USA. Overall, 1891 red drum larvae and early juveniles (4 to 30 mm standard length. SL) were identified from weekly epibenthic sled collections taken during the annual recruitment period (September-December 1994). Densities ranged from 0.0 to 3.4...
Varying densities of the spring generation of the hemlock woolly adelgid were manipulated on 16 previously uninfested eastern hemlocks in an open-field plantation in Massachusetts. In contrast to experimentally created hemlock woolly adelgid populations in a forest, as reported previously, there was no evidence of density-dependent survival on a tree-wide basis in the plantation in the spring (...
grey mullet (mugil cephalus) is an important food fish species in the, mugilidae which is able to adapt in a wide range of salinities and temperatures and is suitable for introduction of the species to freshwater, brackish, and brine waters for aquaculture. this study was implemented to determine appropriate normative of stocking density and initial weight ofmugil cephalus and also evaluate eff...
