abstract rice can be cultivated in various soils but soil with heavy texture and low permeability is more appropriate for its growth than other types of soil texture. it’s assumed that existence of zeolite in soil can be effective for moisture retention and avoiding of occurrence of crack in soil. in order to investigation of the effect of zeolite on moisture status and hydraulic properties of ...

PET with 68Ga from the TiO2- or SnO2- based 68Ge/68Ga generators is of increasing interest for PET imaging in nuclear medicine. In general, radionuclidic purity (68Ge vs. 68Ga activity) of the eluate of these generators varies between 0.01 and 0.001%. Liquid waste containing low amounts of 68Ge activity is produced by eluting the 68Ge/68Ga generators and residues from PET chemistry. Since clear...

At least 7 species of Noctuid moths have been reared from caterpillars collected beneath trash in cane fields, and some at least feed at night on leaves of young ratooning sugarcane, the chief offender being Mythimna phaea Hamps. Feeding appeared to be initiated by onset of darkness, but a reduction in numbers feeding occurred before dawn. Natural enemies included 6 Tachinid flies, an Ichneumon...
