We have revisited the stellar content of OMC 2 and OMC 3 by means of MIR imaging and NIR photometry; in addition, we have extended the existing (sub)mm maps by a huge 1200 μm map obtained with SIMBA showing new sources and filamentary features for the first time at that wavelength. The MIR data reveal 43 new sources at N and Q which are partly associated with dense condensations at millimetre w...
Application of green walls still has not attracted interest among the contractors and people, and this can be due to poor growing performance of the plants on these systems. This study investigated the effect of four growing media types (30% cocopeat + 65% perlite + 5% vermicompost, 30% soil + 65% perlite + 5% vermicompost, 30% mushroom compost + 65% perlite + 5% vermicompost and regular soil a...
Background & Objectives: Polycyclic aromatic hydrocarbons (PAHs) are considered as important organic contaminants due to their high toxicity and carcinogenic properties. Among PAHs, phenanthrene is found in most contaminated sites. Sorption and desorption of phenanthrene in soil affect the fate of the contaminant in soil-water system. Presence of organic matter (OM) in the soil matrix can also ...
Maneb is a broad spectrum fungicide, often reported as a carcinogenic, teratogenic and neurodegenerative agent. Thus, the occurrence of maneb at non-targeted sites is a cause of concern. The present study investigates adsorption– desorption behaviour of maneb in the agricultural soils to know its fate, mobility and availability in the soil. The sorption study was carried out by batch equilibrat...
this study was conducted to study the effect of organic acids on the preservation of alfalfa nutritional value after harvesting. a split plot design with 4 treatments and 3 times was conducted in which organic acids were sprayed on the 30percent moisture content forage before baling. treatments were: 1) forage without additives as control, 2) pure propionic acid, 1percent, 3) acetic acid percen...
Determination of vegetation and soil interaction is necessary for sustainable use of rangeland ecosystem. Soil-vegetation interrelationships in galbanum (Ferula gummosa) habitats of Ataeeye and Shoorrud- Khorasan-e- Razavi Province, Iran were studied using multivariate analysis. The stratified- random system of sampling was employed to randomly collect vegetation and soil samples from 46 quadra...

Methyl bromide (CH,Br) is currently the most widely used soil fumigant, and its emission into the atmosphere after application reportedly contributes to ozone depletion in the stratosphere. Irreversible degradation and partially reversible sorption reactions affect the quantity of this fumigant reaching the soil surface and escaping into the atmosphere. Incubation studies in closed headspace vi...
