Abstract The thermal resistance of concrete significantly influences the energy consumption building. Consequently, with high can contribute to envelope’s efficiency. In order obtain conductivity performance required for passive house standard using principles sustainable development, it is essential analyze improvement solutions a low impact on environment. For this reason, necessary methods i...

Sandra M. Duval Mark A. Berhow New Crops and Processing Technology Research, USDA, ARS, National Center for Agricultural Utilization Research, 1815 North University Street, Peoria, IL 61604 Defatted seedmeals from 15 glucosinolate-containing plant species were analyzed for herbicidal activity by determining inhibition of seedling emergence when added to a sandy loam soil containing wheat and si...

Purpose. This study evaluated the P sorption characteristics of soils under smallholding land use in Wolaita Zone, Southern Ethiopia. Methods. Soil samples (0–20 cm) were collected from each home garden, grazing land, cropland, and woodlot three replications at two sites analyzed for isotherm data selected soil properties. Results. The generated by equilibration with solutions fitted Freundlich...

Romaine and Boston lettuce (Lactuca sativa L., Compositae) were identified as economically feasible alternative crops for eastern Virginia (Sterrett et al. 1996; Kalo 1997). Although lettuce is one of the most widely consumed vegetables, much of the production is concentrated in western states. Per capita consumption of leaf lettuce has increased from a low of 1.1 kg in 1986 to an estimated 3.4...

A novel, cost-effective and eco-friendly technologies are needed to remove Zinc from the contaminated soil environment. The present research study was designed to assess the naturally enhanced phytoextration and phytostabilization potential of different plant species from the Zinc (II) contaminated soil. Uptake of Zinc by plant species in a metal contaminated soil was studied in pot culture exp...

This paper presents the results of an experimental study on the residual compressive and splitting tensile strength of autoclaved aerated concrete (AAC) containing perlite and polypropylene (PP) fiber subjected to high temperatures. Cylinder specimens were subjected to various temperature ranges of 100, 200, 400, 800, and 1,000°C. The mixtures were prepared with AAC cementitious materials conta...

This study was undertaken to create an understanding of greywater characteristics and to demonstrate a low cost reuse option involving application of small tower gardens for Greywater treatment and reuse in a peri-urban settlement, Kawaala in Kampala city, Uganda. To realise this, field surveys, greywater and soil sampling and analysis and, tower garden installation at selected households were ...

The wastewater generated in dairy industry contains very high organic loading and total solids and is mostly treated in ETP (Effluent Treatment Plant ), where the sludge is formed increasing the expenditure for processing and disposal along with the operation cost. Earthworms body act as a ‘biofilter’ and they were found to increase the removal efficiency of BOD3 – 89.3 %, 86.5 %, 91.6 %, COD –...
