the present study aimed at estimating the amount of carbon storage and its relationship with other physical and chemical soil properties in four land-use systems including intact, protected, exploited and garden-uses areas in the northern zagros region in west azarbaijan province, iran. thirty sample plots were identified and within each plot, soil samples were taken in each land use and each s...

The development and deployment of practical Semantic Web applications requires technologies for the storage and retrieval of RDF data that are robust and scalable. In this paper, we describe the 3store RDF storage and query engine developed within the Advanced Knowledge Technologies project, and discuss the design rationale and optimisations behind it which enable the efficient handling of larg...

the aim of this study was to investigate the effect of reforestation on physical and chemical soil properties particularly soil carbon storage in the berenjastanak forest. forestations were including acer velotinum boiss., fraxinus excelsior l., populus nigra l. and pinus brutia ten. a witness forest with mixed species was selected as region potential. four soil profiles were drilled in each fo...

bulk tomato paste which is produced by most domestic factories in cocentrations more than 35% (35-40 degree of brix), and filled in to barels as bulk quantity under non - hermetic conditions.the microbial contamination level in this product is high since there is no any post heat treatment. for sterilization and microbial redaction barels maybe stored at coldstore or ambient temperatures for mo...

livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. this research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of artemisia aucheri. hence, two rangelands of enclosure (shahtappeh-chah mahmood) and no enclosure (chiro) were chosen in sem...

an important part of carbon cycling is carried out in the soil making land use changes, including changes in forestlands, affect soc storage and consequently co2 flux into the atmosphere.the aims followed in this investigation were to study the impacts of conversion of deciduous forests to coniferous ones and deforested land to rangelands, on some of the soil physicochemical properties, organic...

We test the common assumption that organic carbon (OC) storage occurs on sand-sized soil particles only after the OC storage capacity on silt- and clay-sized particles is saturated. Soil samples from a Brookston clay loam in Southwestern Ontario were analysed for the OC concentrations in bulk soil, and on the clay (<2 μm), silt (2-53 μm) and sand (53-2000 μm) particle size fractions. The OC con...
