road transport is a ubiquitous source of lead contamination in the soil near highways with direct and indirect impacts on human health. accumulation of traffic-induced lead in the soils depends on gasoline lead content, traffic volume, as well as meteorological conditions. to evaluate the effect of traffic on soil lead concentration, 113 samples from the topsoil (0-15 cm) were collected in a re...

conclusions the brachial plexus block can be performed at different levels in the same patient to achieve desired results, while employing sound anatomical knowledge and adhering to the maximum safe dose limit of the local anesthetic. case presentation we present the case of a 68-year-old gentleman who had brachial plexus block at supraclavicular and interscalene levels as the sole anesthetic f...

kernicterus (bilirubin induced encephalopathy) is an uncommon disorder with tragic consequences, especially when it affects healthy term and near-term neonates. appointment of cut off value of total serum bilirubin level that have a safe margin for early prompt treatment, as a result, prevention of kernicterus. in our study, all of icteric neonates that admitted in our center in 1 year were enr...

Consider an agent interacting with an environment in cycles. In every interaction cycle the agent is rewarded for its performance. We compare the average reward U from cycle 1 to m (average value) with the future discounted reward V from cycle k to ∞ (discounted value). We consider essentially arbitrary (non-geometric) discount sequences and arbitrary reward sequences (non-MDP environments). We...

In this study, the MHD equilibrium limit of LHD plasmas is studied using a 3D MHD equilibrium calculation code, HINT2, which is an initial value solver based on the relaxation method without the assumption of nested flux surfaces. For finite beta equilibria, flux surfaces become stochastic in the peripheral region. However, though the axis shifts until the conventional limit, the separatrix to ...

The asymptotic behavior of value distribution of the Riemann zeta-function ζ(s) is determined for 1 2 < (s) < 1. Namely, the existence is proved, and the value is given, of the limit lim →∞ ( (log )σ)−1/(1−σ) logW (C \R( ), σ, ζ) for 1 2 < σ < 1, where R( ) is a square in the complex plane C of side length 2 centered at 0, and W (A,σ, ζ) = lim T→∞ (2T )−1μ1({t ∈ [−T, T ] | log ζ(σ + t √−1) ∈ A}...

I point out that an upper limit of approximately 20 Gyr (for a Hubble constant of 72 km/s/Mpc) or alternatively on the H 0-independent quantity H 0 t 0 < 1.47, exists on the age of the Universe, essentially independent of the unknown equation of state of the dominant dark energy component in the Universe. Unless astrophysical constraints on the age of the Universe can convincingly reduce the up...
