Flaring emissions during abnormal operating conditions such as plant start-ups, shut-downs, and upsets in chemical process industries (CPI) are usually significant. Flare minimization can help to save raw material and energy for CPI plants, and to improve local environmental sustainability. In this paper, a systematic methodology based on plant-wide dynamic simulation is presented for CPI plant...

I have just moved from south London to a small town in Norfolk. 'Oh, you don't want to do that,' people said. 'You'll miss all the facilities.' I guess they were talking about the off licence that stayed shut for weeks at a time, on account of security problems.

A key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. So, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. The X-ray diffraction patterns indicated that exfoliated ty...

Studies were conducted to determine whether encephalomyocarditis virus infection causes proteolytic cleavage of any of the polypeptides which comprise eucaryotic initiation factor 4F. Since no such alterations in the components of the initiation factor were detected, these observations confirmed that the mechanisms whereby encephalomyocarditis virus and poliovirus shut off host translation are ...

Mammalian 'regulators of G protein signaling' (RGS proteins) help shut off G-protein-mediated signaling by GTPase activation. But new evidence shows that RGS proteins can also speed up the activation of signaling. The combined effect is a change in signaling kinetics without a decrease in signaling intensity.

The herpes simplex virus 1 ICP27 is an essential, highly conserved protein involved in various steps of herpes simplex virus 1 gene regulation as well as in the shut-off of host gene expression during infection. It functions primarily at the post-transcriptional level in inhibiting precursor mRNA splicing and in promoting nuclear export of viral transcripts. These activities are discussed.

One of the major problems faced by oil industry is problem unwanted water production. High rates production in a well can make uneconomical and reduces good lifespan. The paper studies field experiencing large amount majority its wells. data gathered from one Indian Western Offshore Oil Fields have been analyzed to identify several Also, initiatives taken company control high cut has discussed....
