Under anaerobic conditions, competition for pyruvate between the branch point enzymes pyruvate formate lyase (PFL, Km = 2 mM) and fermentative lactate dehydrogenase (LDH, Km = 7.2 mM) determines the partition of carbon flux. Two Escherichia coli mutant strains, one deficient in ackA, pta, and ldhA and the other overexpressing LDH, were constructed to systematically analyze the effects of these ...

Many navigation applications take natural language speech as input, which avoids users typing in words and thus improves traffic safety. However, often fail to understand a user's free-form description of route. In addition, they only support input specific source or destination, does not enable specify additional route requirements. We propose SpeakNav framework that enables describe intended ...

We present an improved calibration of photometric metallicity indicators, derived from the new metallicity scale for Globular Clusters presented by Carretta & Gratton (1997) and based on direct high resolution spectroscopy of 160 stars in 24 globular clusters. We have carefully recalibrated the traditional abundance indices based upon the red giant branch (RGB) morphology, both in the V,B − V a...

This paper compares the Portuguese and Bulgarian consumer price indices (CPI) and attempts to identify some areas in which the CPI compilation methodology could be improved in the two countries. This work is organised into six sections. The first section briefly describes the organisational structure on which the production of the CPI is based in the two countries. The second section focuses on...

Recent progress in the next generation of automobile technology is geared towards incorporating information technology into cars. Collectively called smart cars are bringing intelligence to cars that provides comfort, convenience and safety. A branch of smart cars is connected-car system. The key concept in connected-cars is the sharing of driving information among cars through decentralized ma...

Using the data from the PCA and HEXTE on board the RXTE satellite, we investigate the evolution of the 3-200 keV spectra of the peculiar low mass X-ray binary (LMXB) Cir X-1 along the branches on its hardness-intensity diagram (HID) from the vertical horizontal branch (VHB), through the horizontal horizontal branch (HHB) and normal branch (NB), to the flaring branch (FB). We detect a power-law ...

We present a methodology to extract mechanical dyssynchrony indices from an electrophysiological (EP) contact mapping system that was applied to a database of ten patients undergoing Cardiac Resynchronization Therapy (CRT), before and after the therapy. The mechanical dyssynchrony indices were obtained after post-processing high temporal resolution data recorded at several endocardial positions...

oral contraceptive pills have several side effects especially on the gastrointestinal tract and liver. absorption of low dose (ld) pills by the vaginal route avoids the first pass of the steroids through these tracts and probably has fewer side effects. this study was a cohort study for evaluation of side effects and acceptability of ld pills administered by the vaginal route. in a clinical tri...

We present new high-quality near-infrared photometry of 10 Galactic Globular Clusters spanning a wide metallicity range (−2.126[Fe/H]6 − 0.49): five clusters belong to the Halo (namely, NGC 288, NGC 362, NGC 6752, M 15 and M 30) and five (namely, NGC 6342, NGC 6380, NGC 6440, NGC 6441 and NGC 6624) to the Bulge. By combining J, H and K observations with optical data, we constructed Colour-Magni...

Abstract Finding the shortest travelling distance based on various situations might assist travelers in making a better selection of route decisions. The main goal this paper is to solve routing problem for company’s fleet vehicle (XpressBees) order find best under constraints such as Signalized Intersections, Vehicle Capacity, Customer Demands, and Time Windows reduce transportation costs by u...
