Various grades of stainless steel are used to fabricate the pump impeller, casings, and seals in heavy-duty erosion corrosion conditions. In present study, (SS316L, SS304, SDSS2507) grey cast iron fabrication impellers were taken for analysis solid particle erosion. Experiments conducted on lab-scale slurry pot tester. Fly ash was prepared different concentrations (wt%). Taguchi’s orthogonal ar...

Gerbera is one of the most popular cut flowers in the world. Several experiments have been done on the effect of different chemical compounds on longevity and quality of cut flowers. In the present study, two experiments based on a completely random design with two treatments and three replications were conducted on gerbera cut flower cv. Sorbet. The first experiment examined the effect of BA, ...

The resistance inducing agent 1, 2, 3-Benzothiadiazole-7-carbothioic acid S-methyl ester (BTH) has been demonstrated in triggering defence reactions in crop plants against bacterial, fungal and viral pathogens but also against parasitic weeds of the genus Orobanche. In this study, pot experiments were conducted under greenhouse conditions to evaluate the efficacy of different concentrations of ...

Endophytic fungus BS002 was isolated and characterized from Sophora flavescens by plate method, which has broad antimicrobial activity. Isolation and trace of a new bioactive compound from the fungus' culture extracts with the method of column chromatography and TLC biological autoradiography was conducted. Finally, it was identified as 6,7-(2'E) dibutenyl-5,8-dihydroxy-(Z)-cyclooct-2-ene-1,4-d...

The fundamentals of growth-linked biodegradation occurring at low substrate concentrations are poorly understood. Substrate utilization kinetics and microbial growth yields are two critically important process parameters that can be influenced by low substrate concentrations. Standard biodegradation tests aimed at measuring these parameters generally ignore the ubiquitous occurrence of assimila...

A wild type strain ofVerticillium lecanii and a mutant strain with increased tolerance to the fungicide benomyl were evaluated in greenhouse experiments for effects on Heterodera glycines populations. Nematodes were applied at 300 eggs and juveniles per 4,550-cm(3) pot (two soybean plants in 4,990 g loamy sand per pot) and at both 300 and 10,000 eggs and juveniles per 1,720-cm(3) pot (one soybe...

in the present study, effect of five isolates of trichoderma harzianum on growth parameters of tomato was carried out as cr design with six replications under greenhouse conditions. the concentrations 0.5%, 1% and 1.5% inoculums per pot were used. plant length, shoot and root fresh/dry weight, number of leaves and stem diameter as growth parameters were measured. the results showed that isolate...
