摘要:
Cell-free extracts, methods for producing these extracts, methods for using these extracts, compositions that facilitate production of these extracts and kits that contain these extracts are provided. By increasing or decreasing certain gene products through, for example, the use of siRNA or mimics, one can develop mammalian cell-free extracts that have desired levels of efficiency.

A color photographic film having a support, 2 or 3 red-sensitive, cyan-coupling silver halide emulsion layers, 2 or 3 green-sensitive, magenta-coupling silver halide emulsion layers, 2 or 3 blue-sensitive, yellow-coupling silver halide emulsion layers, conventional interlayers and protective layers together with a yellow filter layer arranged closer to the support than the blue-sensitive layers, wherein at least one green-sensitive silver halide emulsion layer is arranged further away from the support than all the other photosensitive layers, exhibits improved sharpness without color distortion if at least 50% of the projected surface area of the silver halide emulsion of the green-sensitive silver halide emulsion layer, of which there is at least one, consists of tabular silver halide grains having an aspect ratio of at least 3.
摘要:
Process for producing C2+ alcohols from a methane-containing feedstock, by passing the methane-containing feedstock and CO2 to a non-oxidative reforming process to produce a product stream containing CO, H2 and CO2, optionally in the presence of steam, provided that where steam is present in the feed to the reforming process, the steam and CO2 are present in a molar ratio of less than 5:1. The CO, H2 and CO2 stream is passed to a bacterial fermentation step where it is converted to a liquid product stream containing one or more C2+ alcohols and a gaseous product stream containing CO, H2 and CO2. The fermentation step is operated to provide a conversion of CO of at least 60%. CO, H2 and CO2 are recycled from the gaseous product stream to the reforming process such that the H2 reacts with carbon dioxide in the reforming process.
摘要:
The present invention relates to a process for the production of one or more C2+ alcohols. In particular, the present invention relates to a process for the production of C2+ alcohols from a methane-containing feedstock, which process comprises: a. Passing said methane-containing feedstock and carbon dioxide to a non-oxidative reforming process to produce a first product stream comprising CO, H2 and CO2, optionally in the presence of steam, but with the proviso that where steam is present in the feed to the reforming process the steam and CO2 are present in a molar ratio of less than 5:1, b. Passing the first product stream comprising CO, H2 and CO2 to a bacterial fermentation step wherein it is converted to produce a second product stream comprising one or more C2+ alcohols in the liquid phase and a gaseous third product stream comprising CO, H2 and CO2, the fermentation step being operated to provide a conversion of CO of at least 60%, wherein CO, H2 and CO2 are recycled from the gaseous third product stream to the reforming process of step (a).

摘要:
A color photographic recording material having a film support and, arranged thereon, at least one red-sensitive silver halide emulsion layer containing a cyan coupler, at least one green-sensitive silver halide emulsion layer containing a magenta coupler, at least one blue-sensitive silver halide emulsion layer containing a yellow coupler and optionally further non-photosensitive layers contains, in addition to conventional sensitizing dyes, in at least one of the red-sensitive silver halide emulsion layers thereof and in at least one of the green-sensitive emulsion layers thereof at least one cyanine dye in each layer having an absorption maximum in a methanolic solution in the range from 515 to 550 nm, wherein the absorption maxima of the additional cyanine dye in the red-sensitive silver halide emulsion layer and of the additional cyanine dye in the green-sensitive layer, in each case measured in a methanolic solution, are no more than 10 nm and preferably no more than 5 nm apart. In a preferred embodiment, the additional cyanine dye in the red-sensitive silver halide emulsion layer is identical to the additional cyanine dye in the green-sensitive silver halide emulsion layer. The recording material exhibits improved sensitivity and improved color reproduction.
摘要:
A color photographic silver halide material which contains as photosensitive layers on a support at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler and at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, in which, above a photosensitive layer (seen from the support outwards), at least one further layer is provided which contains a colorless compound or combination of colorless compounds, which under processing conditions after exposure gives rise to a uniform, slight color density of a predetermined color and predetermined density over the entire surface, allows correction of the print densities without sensitivity being reduced.
摘要:
An electronic brake controller operates in both an automatic and manual mode. In the automatic mode, the electronic brake controller applies a pre-specified percentage of braking for the brakes of a towed vehicle. In the manual mode, the electronic brake controller is capable of applying one-hundred percent of braking regardless of the setting for the pre-specified percentage of braking set for the automatic mode.
