The gene for ciliary neurotrophic factor (CNTF) was cloned from a human genomic DNA library by screening with a DNA fragment amplified from human genomic DNA using the polymerase chain reaction. A DNA sequence coding for human CNTF was placed under control of an regulatable promoter in the expression vector pJU1003 and transformed into Escherichia coli(More)
The development of the Multi-Sensor Towed Array Detection System (MTADS) for unexploded ordnance (UXO) detection has resulted in the generation of highly registered magnetic signature data for many different UXO and UXO-like objects. The data collected by MTADS provides a unique opportunity to develop and test UXO signature models because of the high(More)
The technique of saturation spectroscopy is applied to measure the concentration of C(2) in the (3)II(u) state in oxyacetylene flames. The two level model is further developed and extended for use in intensity regions slightly lower than that required to saturate the resonances completely. As a result, it has proved feasible to measure both the C(2) number(More)
