XXXVI. Orchidaceae novae et criticae

Recurrent Novae , Classical Novae , Symbiotic Novae , and Population II

Light curve analysis of decay phase of nova outburst are summarized. Nova duration is determined by the strong wind mass-loss which depends only on the white dwarf mass. Fast novae correspond very massive white dwarfs and very slow novae correspond almost lower mass limit of white dwarfs. This relation is shown in both of classical novae and recurrent novae. Light curves are theoretically repro...

The COPD Pipeline XXXVI.

Contract Pharma is a publication that reviews, among other things, the pharmaceutical industry annually. Those of us who work in chronic obstructive pulmonary disease (COPD) take an interest in the source of the drugs we use and Contract Pharma brings that information to us. Each year they report the status of the top 25 pharmaceutical companies.1 For each pharma, a report lists the newly appro...

Clinical studies of induction agents. XXXVI: Ketamine.

The intravenous anaesthetic ketamine has been given to patients undergoing minor gynaecological surgery after atropine prcmedication in initial doses ranging from 1.0 to 3.0 mg/kg. The chief induction complications were hypertension and hypertonus, the incidence of which was only broadly related to dosage. Recovery of consciousness was rapid, though marred by a high incidence of delirium at all...

Lecture XXXVI: Introduction to cosmological perturbations

We begin by considering a spatially flat FRW universe, which has background metric ds = a(η)(−dη + δijdxdx). (1) Note here that we use the conformal time η instead of t as our time coordinate, for consistency with the rest of cosmological perturbation theory. In this case, the spatial metric is γij(η, x ) = a(η)δij . We will also introduce the conformal Hubble rate, H(η) = d ln a(η) dη = aH (2)...
