Isolated pulsar population synthesis with simulation-based inference
(2024-06-05)We combine pulsar population synthesis with simulation-based inference (SBI) to constrain the magnetorotational properties of isolated Galactic radio pulsars. We first develop a framework to model neutron star birth ... -
Isolated starless cores in infrared dark clouds in the Hi-GAL survey
(2012-07-01)In a previous paper, we identified cores within infrared dark clouds. We regarded those without embedded sources as the least evolved and labelled them starless. Here we identify the most isolated starless cores and model ... -
An Isolated ZVS DC/DC Converter with Diode-connected MOSFET in Rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 2022-02-02)This paper presents an isolated resonant zero voltage switching ZVS converter with a diode-connected MOSFET in a rectifier. The active resonant network is the composition of a resonant capacitor, a transformer leakage ... -
Isolating signatures of major cloud-cloud collisions - II. The lifetimes of broad bridge features
(2015-12-01)We investigate the longevity of broad bridge features in position–velocity diagrams that appear as a result of cloud–cloud collisions. Broad bridges will have a finite lifetime due to the action of feedback, conversion of ... -
Isolating signatures of major cloud-cloud collisions using position-velocity diagrams
(2015-06-01)Collisions between giant molecular clouds are a potential mechanism for triggering the formation of massive stars, or even super star clusters. The trouble is identifying this process observationally and distinguishing it ... -
Isolation and amplification of human IgE Fd encoding mRNA from human peripheral blood lymphocytes
(1992-04-27)In order to establish the feasibility of applying recombinatorial library technologies to investigate human in vivo IgE responses, and as a pre-requisite of recombinatorial library construction, we have attempted to determine ... -
Isolation and characterisation of the mating-type (MAT) locus from Rhynchosporium secalis
(2003-12-31)The mating-type (MAT) genes from Rhynchosporium secalis were isolated using PCR-based methods. Characterisation of the MAT idiomorphs suggests that R. secalis is closely related to the discomycetes Pyrenopeziza brassicae ... -
Isolation and characterization of extracellular vesicles and future directions in diagnosis and therapy
(2023-01-13)Extracellular vesicles (EVs) are a unique and heterogeneous class of lipid bilayer nanoparticles secreted by most cells. EVs are regarded as important mediators of intercellular communication in both prokaryotic and ... -
Isolation and characterization of genes induced during non-host resistance to Polymyxa spp

The isolation and culture of cucumber mesophyll protoplasts
(1975-03-01)Large numbers of viable protoplasts were obtained from the first leaves of two cultivars of cucumber, Cucumis sativus L. cv. Ashley and China. Cell wall regeneration was observed in liquid culture within 3 days of isolation, ... -
Isolation of an RNA-dependent RNA polymerase from Nicotiana benthamiana plants infected with Tobacco necrosis virus (strain D) and template-dependent transcription of its satellite, Satellite tobacco necrosis virus (strain C) RNA
(2001-04-01)Partially purified RNA-dependent RNA polymerase activity isolated from Nicotiana benthamiana plants infected with Tobacco necrosis virus strain D (TNV-D) is capable of template-dependent synthesis of Satellite tobacco ... -
Isolation of microcrystalline cellulose from wood and fabrication of polylacticacid (PLA) based green biocomposites
(2024-08-02)An innovative microcrystalline cellulose (MCC) natural fibre powder-reinforced PLA biocomposite was investigated using the hand lay-up technique. The polymer matrix composite (PMC) samples were prepared by varying the weight ... -
Isolation of microvesicles and exosomes by microfiltration and estimation of normal reference range in blood plasma.
(2012-09-13)Current protocols for the isolation of microvesicles (MVs) and exosomes, which in the main focus on differential centrifugation, vary considerably (1). In an attempt to set a new standard, we describe a filtration protocol ... -

Isometamidium in goats : disposition kinetics, mammary excretion and tissue residues
(1990-09)The pharmacokinetics of the antitrypanosomal drug isometamidium were studied in lactating goats after intravenous and intramuscular administration at a dose of 0.5 mg/kg body weight, in a crossover design at an interval ... -
Isometamidium in pigs : disposition kinetics, tissue residues and adverse reactions
(1991-01)The disposition and adverse effects of the anti-trypanosomal drug isometamidium in pigs were evaluated. Following intramuscular administration of the drug at doses of 0.5, 15 and 35 mg kg-1, the drug was rapidly absorbed ... -
Isometric and isovelocity contractile performance of red muscle fibres from the dogfish Scyliorhinus canicula
(2002-06)Maximum isometric tetanic force produced by bundles of red muscle fibres from dogfish, Scyliorhinus canicula (L.), was 142.4+/-10.3 kN m(-2) (N=35 fibre bundles); this was significantly less than that produced by white ... -
Isopimaric acid from Pinus nigra shows activity against multidrug-resistant and EMRSA strains of Staphylococcus aureus
(2005)The diterpene isopimaric acid was extracted from the immature cones of Pinus nigra (Arnold) using bioassay-guided fractionation of a crude hexane extract. Isopimaric acid was assayed against multidrug-resistant (MDR) and ... -
Isospectral mapping for quantum systems with energy point spectra to polynomial quantum harmonic oscillators
(2021-03-15)We show that a polynomial Hˆ(N) of degree N of a harmonic oscillator hamiltonian allows us to devise a fully solvable continuous quantum system for which the first N discrete energy eigenvalues can be chosen at will. In ...
