We describe a way to combine the method of fictitious sources and the scattering-matrix method. The resulting method presents concurrently the advantages of these two rigorous methods. It is able to solve efficiently electromagnetic problems in which the structure is made up of a jacket containing an arbitrary set of scatterers. The method is described in a two-dimensional case, but the basic i...

A 41-year-old man was provided with a jacket crown after a root end resection of a molar. Four months later, cortical destruction of the ulnar diaphysis with swelling and pain appeared in his forearm. No microorganism could be grown from an intraoperative tissue specimen, but bacterial 16S rRNA genes were detected by broad-range PCR, revealing Porphyromonas gingivalis as the causative agent of ...

1. An Amberlite XAD-2 column in a heated (37 degrees C) jacket was incorporated in between two banks of bioassay organs superfused with Krebs bicarbonate solution in cascade. The column removed prostaglandins, E1, E2 and F2alpha and also rabbit aorta contracting substance (RCS) and possibly slow reacting substance of anaphylaxis (SRS-A). 2. The column gave free passage to histamine in concentra...

The utility of microwave oven for simple and rapid acid digestion of zoological and botanical materials was investigated by using a double Teflon vessel with a polypropylene jacket. The microwave-assisted digestion of samples with the HNO3-HCI-HCIO4-HF mixture in the bomb offers the advantage of taking much shorter process for sample preparation. The digestion was completed within 15 min even u...

Introduction: Mass independent sulfur isotopic compositions have been observed in chondritic chondrules and organics [1, 2] and in bulk CM chondrites, achondrites and iron meteorites [3-6]. A significant excess of ∆33S (= δ33S – 0.515 δ34S) was observed in the Dhajala chondrite. Sulfonic acid extracts from the carbonaceous chondrite, Murchison also displayed a significant 33S anomaly and may be...

Drought is an important factor limiting crop production in arid and semi-arid conditions. Drought indices which provide a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions. Ten barle...

We report on infrared supercontinuum generation extending over more than one octave of bandwidth, from 850 nm to 2.35 μm, produced in a single spatial mode from a robust, compact, composite chalcogenide glass nanotaper. A picosecond laser at 1.55 μm pumps a high-index-contrast, all-solid nanotaper that strongly confines the field to a 480 nm diameter core, while a thermally compatible built-in ...

This study replicates and extends prior research showing that access to self-restraint materials can reinforce self-injurious behavior (SIB). A functional analysis was conducted showing that SIB occurred at differentially high rates when access to restraint materials (a leather jacket) was made contingent on the behavior. In addition, an alone condition during the functional analysis showed tha...
