Perlite is a generic name for an amorphous volcanic alumina-silicate rock that expands by a factor of 4-20 when rapidly heated to 1400-1800 °F (760-980 °C). Both the ore and the expanded product have extensive and widespread commercial applications. Limited data on the toxicology of perlite in animal studies indicate that the LD₅₀ (oral ingestion) is more than 10 g/kg and, from a chronic inhala...

Earthworms (Aporrectodea caliginosa, Lumbricus rubellus, and Octolasion lacteum) obtained from nitrous oxide (N(2)O)-emitting garden soils emitted 0.14 to 0.87 nmol of N(2)O h(-1) g (fresh weight)(-1) under in vivo conditions. L. rubellus obtained from N(2)O-emitting forest soil also emitted N(2)O, which confirmed previous observations (G. R. Karsten and H. L. Drake, Appl. Environ. Microbiol. 6...

in order toa desirable growth, plants need fertile soil which has the availability of nutrient elements in it. sometimes, in spite of having access to the nutrient elements, decrease yield, due to undesirable physical situation. stock (matthiolaincana cv. column crimson) is one of the potting flower that its growth medium traditionally including hawar soil, basin sediment and untreated waste mu...

due to the notable role of different land uses in carbon sequestration and emission, four treatments including rangeland as control, haloxylon plantation area, olea plantation (olive garden), and residential lands, were selected to study the effects of land use change on soil carbon sequestration and emissions in eivanakei rangelands, semnan province. carbon stocks in vegetation and soil of eac...

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...

Fifty Fusarium isolates were obtained from 20 garden soil samples in Hormozgan province (S Iran). The isolates were identified based on morphological and molecular data. Sequence data were generated for TEF-1αgene, following PCR amplification. Among the identified species, Fusariummangiferae, F.gaditjirrii, and F. decemcellularerepresent new records to the mycobiota of Iran.

The purpose of this paper is to evaluate the possibility of paleoentomology as a proxy in garden archaeology research. Garden contexts can prove difficult to identify and interpret due to the many changes the contexts go through during their activity period. Mixing of materials, harvesting and cultivation of many different plants will affect the environmental data that is retrieved from them an...
