Washing Out Flasks by Inversion

Washing out the Uterine Cavity

Washing carbon out of the air.

Jo e Ze ff D es ig n The world cannot afford to dump more carbon dioxide into the atmosphere. Yet it is not cutting back. All indications are that the concentration of CO2 will continue to rise for decades. Despite great support for renewable energy, developed and developing countries will probably burn more oil, coal and natural gas in the future. For transportation, the alternatives to petrol...

A simple device for washing out radioimmunoassay tubes.

The use of disposable polystyrene tubes for radioimmunoassay is now widespread. Washing out such tubes before disposal is tedious and time-consuming, especially if they contain dense charcoal or doubleantibody pellets. In this laboratory the simple device described below has much reduced the time and tedium involved in this task. It was constructed in a frew minutes for a cost of a few pence. *...

Data regularization: inversion with azimuth move-out

Data regularization is cast as a least-squares inversion problem. The model space is a five-dimensional (t,cmpx, cmpy, hx, hy) hypercube. The regularization minimizes the difference between various (t, cmpx, cmpy) cubes by applying a filter that acts in (hx,hy) plane. Azimuth Move-out is used transform the cubes to the same ( hx,hy) before applying the filter. The methodology is made efficient ...

Fungicide assay by spore germination in shaker flasks.

Since the introduction in 1933 (Kluyver and Perquin, 1933) of the shaker flask method of culturing fungi this technique has found widespread use in fungus physiology (Foster, 1949). It was used for spore germination studies by Davies et al. (1948) and Mandels and Norton (1948). The measurement of antifungal activity, however, has been accomplished by the more conventional methods making use of ...
