Molecular biology techniques require the isolation of individual clones for analysis after bacterial or yeast transformation. For E. coli and Saccharomyces cerevisiae, the dispersion of colonies on plates has traditionally involved the use of a glass spreader—a bent glass rod that could be repeatedly flame sterilized and used to spread a small aliquot of microorganisms from the center of the pl...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

Carbon Capture & Storage (CCS) is one of the various methods that can be used to reduce the carbon footprint of the energy sector. This paper focuses on the absorption of CO2 from flue gas using packed columns, whose efficiency is highly dependent on the structure of the liquid films within the column. To study the characteristics of liquid films a CFD solver, OpenFOAM is utilised to solve two-...

the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

A reaction diffusion system with a distributed time delay is proposed for virus spread on bacteria immobilized on an agar-coated plate. A distributed delay explicitly accounts for a virus latent period of variable duration. The model allows the number of virus progeny released when an infected cell lyses to depend on the duration of the latent period. A unique spreading speed for virus infectio...

Since 1938, nine cases of nasopharyngeal involvement by craniopharyngioma have been described in the medical literature (1–3). Six of these cases involved the sella turcica, and all but one (1) extensively involved the sphenoid sinus. We report a case of a nasopharyngeal craniopharyngioma sparing the sella turcica. The tumor is thought to have likely arisen from the pharyngeal hypophysis. Magne...
