摘要:
A cloning and/or sequencing vector (1) comprises a nucleotide promoter sequence (3) and a nucleotide sequence (4) coding for a fusion protein active as a poison, which nucleotide sequence (4) is obtained by fusion of a coding nucleotide sequence (5) containing several unique cloning sites with a nucleotide sequence (6) coding for a poison protein, wherein the nucleotide sequences (3) and (4) are incorporated in an autonomous replication vector (2).
摘要:
Carbon dioxide is facilely converted into carbon monoxide and water, and advantageously into a syngas, by establishing a thermally homogeneous gaseous admixture including carbon dioxide and hydrogen having a temperature of at least 800.degree. C., within a period of time essentially insufficient for the production of carbon monoxide therefrom, and wherein said carbon dioxide is next autogenously reduced under reaction equilibrium conditions to carbon monoxide and water by reaction with hydrogen, with each molecule of carbon monoxide formed having, or essentially instantaneously being brought to, a temperature of at least 800.degree. C.

摘要:
A technique includes receiving seismic data acquired by seismic sensors; and processing the seismic data on a machine to deghost the data. The processing includes deghosting the seismic data using a first deghosting technique that relies on a ghost model; deghosting the seismic data using a second deghosting technique that is independent from any modeling of the ghost; and selectively combining the results of the deghosting using the first and second deghosting techniques.
摘要:
The invention relates to a device for measuring patient compliance with oxygen therapy, including a casing (4) comprising means for detection of the oxygen therapy in order to evaluate data relating to the treatment; and means for measuring a state of physical activity of the patient. Preferably, the means for measuring a state of physical activity of the patient comprise at least one sensor which senses movement of the patient's body and outputs data relating to the spatial displacement of the patient's body, for example a three-dimensional accelerometer (28); and processing means (40, 42) for processing the body displacement data in order to supply a state of physical activity of the patient chosen from a sleeping state, a resting state and an active state.
