AIMS To assess the toxic potential of different local Jordanian Bacillus thuringiensis isolates on larvae of Drosophila melanogaster and Culex sp. METHODS AND RESULTS Scanning electron microscopy revealed the presence of spherical, bi-pyramidal, and bi-pyramidal and cuboidal parasporal bodies produced by the toxic isolates. Spherical inclusions dominated.(More)
—Establishing real-time models for electric motors is of importance for capturing authentic dynamic behavior of the motors to improve control performance, enhance robustness, and support diagnosis. Quantized sensors are less expensive and remote controlled motors mandate signal quantization. Such limitations on observations introduce challenging issues in(More)
A survey of Bacillus thuringiensis was conducted for 17 locations in Northern Jordan representing 12 different habitats. Eighty isolates were identified as B. thuringiensis in the majority of the tested samples. Results showed that soils contaminated with the slaughterhouses waste materials had the highest content of spore-forming bacteria [(4.05-2.2) 10(7)(More)
Glutathione S-transferase activity toward 1-chloro-2,4-dinitrobenzene was detected in various developmental stages of Drosophila melanogaster. The specific activity of the enzyme was 110, 35, 25 and 15 nmol/min/mg protein in crude extracts prepared from eggs, larvae, pupae and adult stages respectively. The enzymes from larval, pupal and adult stages were(More)
