Organic agriculture is an ecological production management system aimed at sustainableproduction of safe food, environmental protection and maintenance of soil health. The objectiveof this study was to evaluate, in a period of organic transition, the effects of different organicfertilizers on wheat yield, grain quality and soil characteristics. The research was performedin an experimental farm ...

Different types of iron oxides deposits have been identified along the Khaf – Dorouneh volcanic and plutonic belt in north east of Iran. Kuh-e-Zar is one of these ore deposits known as Fe- oxide gold deposit. The main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the ETM+ data. Data processing has been done by ENVI (Environment for Visualizing...

one and two dimensional contaminant transport by pure diffusion through single layer of fine grained soil was investigated using one and two dimensional laboratory models. these models simulates a simple hydrogeologic situation underneath a solid waste landfill comprising a fine grained soil overlying a bed rock. sodium chloride solution was sued as a contaminant source above a compacted clayey...

Context-sensitive global analysis of large code bases can be expensive, which can be specially problematic in interactive uses of analyzers. However, in practice each development iteration implies small modifications which are often isolated within a few modules, and analysis cost can be reduced by reusing the results of previous analyses. This has been achieved to date on the one hand through ...

Skew is one of the most important parameter that decides the performance of the system. Though skews are reduced using two-stage(low and high voltage levels) serially connected power mode aware buffers(PMABs) using two power gating techniques-Fine grain technique at high voltage level and Coarse grain technique at low voltage level, the power consumption and area is large incase of fine grain t...

In this paper we present VirtuosoNext, an RTOS for distributed heterogeneous systems which provides fine-grain space and time partitioning. Focusing on the Space Partitioning, the benefits and penalties of fine-grain space partitioning for real-time systems are presented by comparing VirtuosoNext to its predecessor OpenComRTOS-1.6. Both use a static memory model and can be used simultanueously ...

A long-term experiment was carried out under field conditions in Jaboticabal, SP, Brazil, with the objective of evaluating the concentration of Ba in soil and in maize plants grown in a soil treated with sewage sludge for nine consecutive years. During 2005/2006, maize was used as test plants and the experimental design was in randomized complete blocks with four treatments and five replicates....

Fine root dynamics control a dominant flux of carbon from plants and into soils and mediate potential uptake and cycling of nutrients and water in terrestrial ecosystems. Understanding of these patterns is needed to accurately describe critical processes like productivity and carbon storage from ecosystem to global scales. However, limited observations of root dynamics make it difficult to defi...

An initial application of CPT results is to evaluate soil type and soil stratigraphy. One of the more common CPT-based methods to estimate soil type is the chart suggested by Robertson et al (1986) based on cone resistance, qc and friction ratio, Rf. Although newer charts have been developed based on normalized parameters, the simple chart based on qc and Rf is still popular because it is easy ...
