The FNR protein of Escherichia coli controls the transcription of target genes in response to anoxia via the assembly-disassembly of oxygen-labile iron-sulfur clusters. Previous work identified patches of surface-exposed amino acids (designated activating regions 1 and 3 [AR1 and AR3, respectively]) of FNR which allow it to communicate with RNA polymerase (RNAP) and thereby activate transcripti...

This study was conducted to compare the profile of patients attending the pediatric emergency services of a tertiary care teaching and referral hospital, Chandigarh, and a community level hospital in Ambala district, Haryana. Records of children (<or=12 years) attending emergency services over a period of one year; from 1st March 1999 to 28th February 2000, at both the health facilities were an...

Thus, the smoking) are frequent risk factors in the countries are committing a large proporRegion’s developing countries which tend tion of their health care resources to ARl to increase the incidence and severity of cases. However, this high expenditure AR1 episodes in children. does not translate into a large impact on the problem for several reas...

In this paper the tracking performance of a transmit antenna weight adaptation algorithm applied in a fading channel is considered. The system uses a stochastic gradient algorithm incorporating gradient sign feedback from a receiving unit to adjust the transmit weights. The feedback is simply a bit indicating which of two normalized perturbed transmission weights delivers greater power to the r...

Many processes concerning below-ground plant performance are not fully understood, such as spatial and temporal dynamics their relation to environmental factors. Accounting for these patterns is very important they may be used adjust the estimation of cassava fresh root yield masked by field heterogeneity. The an characteristic that every breeder seeks maintain in germplasm. Ground-Penetrating ...

Forced aeration is one of the promising ways to accelerate landfill reclamation, and understanding relation between rates waste properties prerequisite implementing forced under target energy saving carbon reduction. In this work, reclamation processes with were simulated using aged refuses (ARs) 1, 4, 7, 10, 13 disposal years, potential field application was also investigated based on a projec...
