In order to achieve the highest resolution in aberration-corrected (AC) high-resolution transmission electron microscopy (HRTEM) images, high electron doses are required which only a few samples can withstand. In this paper we perform dose-dependent AC-HRTEM image calculations, and study the dependence of the signal-to-noise ratio, atom contrast and resolution on electron dose and sampling. We ...

where α = max(|D(ui)|, |D(uj)|)+ ; is a small positive number. For notational simplicity, we denoteD(xi) = D(ui)xi, V (xi, xj) = V (ui, uj)xixj , V̂ (xi, xj) = V̂ (ui, uj)xixj , andR(xi, xj) = R(ui, uj)xixj . Lemma 1. If X∗ is the global optimum of E(X),R(xi, xj) < To,∀ xi ∼ xj , xi, xj ∈ X∗. Proof. If there exists a pair xi ∼ xj , xi, xj ∈ X∗ such thatR(xi, xj) ≥ To, then E(X∗) > 0 = E(0) (5) wh...

On the basis of degradation properties of Phanerochaete chroysosporium ME 446 found in white-rot fungi in respect of many organic compounds with toxic, mutagenic and carcinogenic characteristics, the physiological conditions effective for the degradation of heptachlor (1, 4, 5, 6, 7, 8, 8heptachloro-3a, 4, 7, 7a-tetrahydro-4, 7-methanoindene), an organic chlorine used in insecticides Phanerocha...

An optimum representative-frames (r-frames) selection method using step-wise function approximation has been developed to provide automatic indexing for a video-queryagent (VQA) system. It uses dynamic programming to simultaneously select the r-frames and corresponding segment boundaries. Experiments showed that the approximation error of the selected r-frames was less than that of two conventi...

Given a transmitter that radiates an electromagnetic light field, we assume that the resulting field at the plane of the receiver aperture is log-normal with some coherence properties. Various representations of the field a r e discussed: aperture sampling, plane-wave decomposition, and Karhunen-Logve expansion. The statistical properties of the coefficients in these representations a r e inves...

The notorious Staphylococcus aureus resistant strains with ever changing resistance patterns have limited treatment options and have led to substantial number of deaths. Almost dried antibiotic pipeline has led us to look into combinations of already approved antibiotics for tackling rising incidence of antibacterial resistance. Recommended use of vancomycin and ceftriaxone together for treatin...

There is controversy about the optimum dose of neostigmine for antagonizing neuromuscular block. We have studied 57 patients undergoing gynaecological surgery to establish a dose-response relationship when neostigmine was given to antagonize atracurium-induced block. Anaesthesia was induced with thiopentone and fentanyl and maintained with nitrous oxide and enflurane in oxygen and neuromuscular...

The effective removal of heavy metals from aqueous wastes is among the most important issues for many industrialized countries. Removal of arsenic (As) from aqueous solutions was studied using Rhazia stricta biomass. The batch experiments are carried out to investigate the effect of the significant process parameters such as pH, contact time, solute concentration and adsorbent dose. The optimum...

In this paper we analyse the dynamics of an inhibitor I which can either bind to a receptor R or to a plasma protein P. Assuming typical association and dissociation rates, we find that after an initial dose of inhibitor, there are three time scales: a short one, measured in fractions of seconds, in which the inhibitor concentration and the plasma-protein complex jump to quasi-stationary values...

One of the most valid and efficient models of long rod projectile penetration in homogeneous targets is Tate and Alekseevskii’s (A&t) model. Based on Tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. The proposed collision speed-penetration depth diagrams are developed using Tate’s model. In this way, va...
