A leptonic-hadronic model for the afterglow of gamma-ray burst 090510

open access: yes, 2010
We model multiwavelength afterglow data from the short Gamma-Ray Burst (GRB) 090510 using a combined leptonic-hadronic model of synchrotron radiation from an adiabatic blast wave.

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Time-Resolved Ultraviolet Observations of the Globular Cluster X-ray Source in NGC 6624: The Shortest Known Period Binary System

open access: yes, 1997
Using the Faint Object Spectrograph (FOS) aboard the Hubble Space Telescope, we have obtained the first time-resolved spectra of the King et al. ultraviolet-bright counterpart to the 11-minute binary X-ray source in the core of the globular cluster NGC ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

NGC 2207/IC 2163: A Grazing Encounter with Large Scale Shocks [PDF]

open access: yes, 2011
Radio continuum, Spitzer infrared, optical and XMM-Newton X-ray and UVM2 observations are used to study large-scale shock fronts, young star complexes, and the galactic nuclei in the interacting galaxies NGC 2207/IC 2163.

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

On the Ultraviolet Rays.

open access: yesJOURNAL OF THE ILLUMINATING ENGINEERING INSTITUTE OF JAPAN, 1928
此の講演は自分の研究の結果を發表したのではなく, 今日まで多くの人々によつて研究された事柄を目次に示すやうに分類し, 紫外線の呈する多くの作用を述べ, それが實際上如何なる方面に應用されて居るかを解説したものである。日光は保健上有効であると云ふことは二千年の昔から知られて居たが, それは學術的に根据はなかつた。日光の中に紫外線のあることは十九世紀の始めに發見された。それから漸次日光の中の紫外線が人體に有効であると云ふことが知られ, 紫外線の分量の多い高山に療養所が出來るやうになつた。而して今日では尚張い紫外線を出す人工的の光源を病症治癒のために用ひるやうになつた。既は紫外線の有する殺菌作用及生理的亢進作用に依るのである。又紫外線の有する螢光作用及燐光作用は寳石, 手形 ...
