From the results of a large series of calorimetric studies with artificially dried grasses (Armstrong, 1964), it was found that the value of a dried grass as an energy source for sheep could be predicted from considerations of its species and its chemical composition (Armstrong, Blaxter & Waite, 1964). The question arises whether the nutritive value of fresh grass can be inferred from that of d...

The genus Calliscelio Ashmead is presumed to be a diverse group of parasitoids of the eggs of crickets (Orthoptera: Gryllidae). A least one species has been found to be an important factor in depressing cricket pest populations. The New World species of Calliscelio are revised. Forty-two species are recognized, 3 are redescribed: Calliscelio bisulcatus (Kieffer), Calliscelio laticinctus Ashmead...

T H I S BOOK'S CONTRIBUTING AUTHORS present practical management tools and techniques needed to cope with the uncertain future of healthcare. Although the book is directed to professionals in the Johnson & Johnson-Wharton Fellows Program in Managemen t for Nurses, other healthcare managers will find the information useful. The work of 11 contributing authors is organized in three parts: plannin...

Recently we have demonstrated that grass and cut grass are important sources of volatile organic compound (VOC) emissions into the atmosphere. The production of these VOCs can be traced back to plant growth, maintenance and wound defence mechanisms. The gases emitted as part of these wound defence mechanisms are responsible for the smell of freshly cut grass, and are also highly photochemically...

In this study, perennial fast growth Napier grass fibers were used for pulp and papermaking. Chlorination and alkaline process were carried using sodium chlorite and sodium hydroxide respectively for pulp extraction from Napier grass. Detailed chemical composition of the Napier grass fibers and the extracted pulp was carried out and a comparison with other perennial grasses made. The extracted ...

Plants are the essential factors shaping soil microbial community (SMC) structure. When most studies focus on the difference in the SMC structure associated different plant species, the variation in the SMC structure associated with phylogenetically close species is less investigated. Legume (Fabaceae) and grass (Poaceae) are functionally important plant groups; however, their influences on the...
