We study the radiation reaction on cosmic strings due to the emission of dila-tonic, gravitational and axionic waves. After discussing the renormalization of the string tension induced by time-symmetric self-interactions (thereby correcting errors in the literature), we concentrate on the nite radiation damping force associated with the half-retarded minus half-advanced \reactive" elds. We revi...

We study the radiation reaction on cosmic strings due to the emission of dilatonic, gravitational and axionic waves. After discussing the renormalization of the string tension induced by time-symmetric self-interactions (thereby correcting errors in the literature concerning the effect of the dilaton field), we concentrate on the finite radiation damping force associated with the halfretarded m...

We study the radiation reaction on cosmic strings due to the emission of dilatonic, gravitational and axionic waves. After verifying the (on average) conservative nature of the time-symmetric self-interactions, we concentrate on the finite radiation damping force associated with the half-retarded minus half-advanced “reactive” fields. We revisit a recent proposal of using a “local back reaction...

PURPOSE Amide type local anesthetic agents are among the most commonly used drugs in medicine. Several adverse drug reactions (ADRs) have been previously described with their use. Among them, allergic reactions are considered rare. The aim of this study was to describe the main characteristics of ADRs induced by amide type local anesthetic drugs. METHODS We studied reports recorded in the Fre...

The present analysis deals with an unsteady magnetohydrodynamic flow of Eyring-Powell nanofluid over an inclined permeable stretching sheet. Effects of thermal radiation, Joule heating, and chemical reaction are considered. The effects of Brownian motion and thermophoresis on the flow over the permeable stretching sheet are discussed. Using Runge-Kutta fourth-order along with shooting technique...

Background & Importance: The use of local hemostatic agents in neurosurgery is mandatory in order to control the sequelae of intracerebal hemorrhage. It is widely used in oxidized regenerated cellulose (Surgicel™). Case Presentation: A 54-year-old man previously operated for grade II meningioma came back to our attention due to the onset of left side arm weakness one month afte...

OBJECTIVE To study local response to BCG vaccination in twin babies and find out the effect of zygosity andchorionicity on BCG uptake. DESIGN Analytical observational study. SETTING Tertiary hospital. METHODS Twin pairs born in the hospital were evaluated for zygosity and chorionicity. BCG vaccination was given within 48 hours of birth to babies >/=33 weeks of gestation and birth weight >...
