In this study, the process of separating and analyzing oils from some plant seeds such as Washingtonia tree Silybum marianum(kulgan) Soxhlat apparatus was used in extraction process, where performed using organic solvents (Hexane Petroleum ether). Then appreciation percentage oil these plants. It found that marianum contain a higher than tree. Then, active functional groups were identified (FT-...

background escherichia coli o157:h7 is an enteric pathogen which can be frequently found asymptomatically in ruminant mammals, but can cause diseases from mild diarrhea to hemolytic uremic syndrome in humans. methods we developed fluorescent amplification-based specific hybridization (flash–pcr) assay to detect the stx-encoding gene stx-1 of e. coli o157:h7. result pcr product of 336 bp was suc...

Tetrapyrazinoporphyrazine with peripheral menthol-thiophenyl substituents was synthesized using Linstead conditions and purified by flash column chromatography. The optimized synthetic purification procedures allowed us to obtain a new macrocycle 36% yield. derivative characterized UV–Vis NMR spectroscopy, as well MS spectrometry. Complex studies 1D 2D techniques the analysis of bulky substitut...

Learning skull radiography techniques is time consuming and difficult, due to the variety of these techniques. Each year, poor employee performance of the radiology unit, impose repetitive radiographs, and a heavy burden on the health system, as well as double exposure of patients and staff. According to the results of the current investigation, comparing student’s opinions revealed that ...

When a flash is presented in spatial alignment with a moving stimulus, the flash appears to lag behind (the flash-lag effect). The motion of the object can influence the position of the flash, but there may also be a reciprocal effect of the flash on the moving object. Here, we demonstrate that this is the case. We show that when a flash is presented near the moving object, the flash-lag effect...

Purpose: To describe a chemoenzymatic approach joining an enzymatic regioselective hydrolysis of peracetylated N-acetyl-α-D-glucosamine (A) with a mild controlled acyl relocation which resulted 2-acetamido-2 deoxy-1,3,6-tri-O-acetyl-α-D-glucopyranose (1B). Methods: Immobilization of lipase on decaoctyl (DSEOD) and octyl-agarose (OSCL) was carried out as reported by the work of Bastida et al. Th...
