Introduction: Cancer is, in essence, a genetic disease and is the second leading cause of death globally. Fortunately, many common types of cancer are treatable if detected early and of course there are many medications and treatments available today. Among the new methods to treat cancer, radiotherapy seems to be hopeful in patients with malignancies. This work investigates th...

We introduce the concept of impedance matching to axion dark matter by posing question why detection is difficult, even though there enough power in each square meter incident dark-matter flux energize a LED light bulb. By quantifying backreaction on field, we show that small axion-photon coupling does not itself prevent an order-unity fraction from being absorbed through optimal match. further...

To determine the opsonic effect of antibodies to Actinobacillus (Haemophilus) pleuropneumoniae outer membrane proteins on phagocytosis by porcine polymorphonuclear leukocytes (PMN), we separated the integral outer membrane proteins (IOMPs) by Triton X-114 extraction. Four major IOMPs with molecular masses of 76, 50, 39, and 29 kDa were detected by sodium dodecyl sulfate-polyacrylamide gel elect...

1. A liver canalicular plasma-membrane fraction enriched 115-155-fold in five marker enzymes relative to the tissue homogenate was obtained by sonication of liver plasma membranes followed by fractionation in iso-osmotic Nycodenz gradients. 2. Two lateral-plasma membrane fractions were also collected by this procedure; the lighter-density fraction was still associated with canalicular membranes...

Introduction: Nuclear medicine techniques have been widely employed in the assessment of gastroesophageal dysfunction. Gastroesophageal reflux (GER) is a common, self-limited process in infants and children that usually resolves at 12 to 18 months of age. Clinical management of GER includes conservative treatment, thickened feedings, positional therapy and parental reassurance. On the other han...

Following two initial campaigns [1], Stellarator Wendelstein 7-X (W7-X) has now completed the construction phase by installation of active cooling all plasma facing components. The machine is presently commissioned for next campaign (OP2) aiming at 1 GJ per pulse, e.g. 100 s 10 MW, eventually 18 GJ, 1800 MW. key heating system Electron Cyclotron Resonance Heating (ECRH) system, consisting gyrot...

The preceding DIN 6800-2 (1997) protocol has been revised by a German task group and its latest version was published in March 2008 as the national standard dosimetry protocol DIN 6800-2 (2008 March). Since then, in Germany the determination of absorbed dose to water for high-energy photon and electron beams has to be performed according to this new German dosimetry protocol. The IAEA Code of P...

Background and purpose: Audit is imperative in delivering consistent and safe radiotherapy and the UK has a strong history of radiotherapy audit. The National Physical Laboratory (NPL) has undertaken audit measurements since 1994 and this work examines results from these audits. Materials and methods: This paper reviews audit results from 209 separate beams from 82 on-site visits to National He...

Fulvic acids extracted from a typical rice-production region near Taihu Lake of China were fractionated into three fractions including F4.8, F7.0 and F11.0 (eluted by pH 4.8 buffer, pH 7.0 buffer and pH 11.0 buffer, respectively). Sorption of fulvic acid (FA) fractions onto kaolinite was studied by batch adsorption experiments, and characterizations of kaolinite before and after adsorption were...

The performance of components produced by conventional route of a thermo mechanical process and those produced by continuous casting is interesting from different aspects of economy and technology. The performance of products in their service depends on their properties which are strongly influenced by production routes. In the present work the hardness, tensile and tensile-impact behaviors of ...
