While one might assume that the force to break a chemical bond gives a measure of the bond strength, this intuition is misleading. If the force is loaded slowly, thermal fluctuations may break the bond before it is maximally stretched, and the breaking force will be less than the bond can sustain. Conversely, if the force is loaded rapidly it is more likely that the maximum breaking force is me...

metronidazole, a synthetic derivative of the nitroimidazole class is a known antibacterial and antiprotozoal agent. the hypolipidemic effect of metronidazole was not known. the authors noticed it incidentally for the first time. after quazi experimental studies on several cases, it was revealed that 750 mg of metronidazole for 10 days significantly decreased serum cholesterol. this trial was pe...

this paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. in this study, some facts (flexible ac transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. each device here is modeled as ...

A new way of supersymmetry breaking involving a dynamical parameter is introduced. It is independent of particle phenomenology and gauge groups. The only requirement is that Lorentz invariance be valid strictly infinitesimally (i. e. Spin(1, 3) be for some values of the parameter replaced by a compact group G with its Lie algebra g = so(1, 3)).

We construct a hybrid inflationary model associated with the superheavy scale MX ≃ 2 × 1016 GeV of the minimal supersymmetric standard model which is based on the simplest superpotential for symmetry breaking and in which the inflaton potential along the inflationary trajectory is essentially provided by quasi-canonical supergravity. The resulting spectrum of adiabatic density pertubations is b...

When CP asymmetries in B(t) → ππ are combined using broken flavor SU(3) with decay rates for B → Kπ and/or B → Kπ, one can obtain stringent limits on the weak phase γ which are consistent with those obtained from other CKM constraints. Experimental data in the past few years have improved to the extent that systematic errors associated with uncertainty in SU(3) symmetry breaking dominate the de...
