TheAsperger Plus Child: How to Identify and Help Children with Asperger Syndrome and Seven Common Co-Existing Conditions
The Asperger Plus Child: How to Identify and Help Children with Asperger Syndrome and Seven Common Co-Existing Conditions is based on current research and the author s clinical observations from working with brilliant, wild, odd, and difficult children for fifteen years. It provides a map that helps them understand better at home and at school. The Asperger Plus Child is written for parents, teachers, counselors, and medical professionals. In this book, George Lynn continues the tradition of breaking new ground in his insights about the children he calls attention different. Some pearls from this work are: Why it is important to understand the real difference between autism and Asperger Syndrome. How you can tell if a child has AS or ADD and why the distinction will become more important as the child grows through his teen years. What a child with AS who also has a nonverbal learning disability looks like compared to a child with AS without an NLD! Though each child is as different as a fingerprint, neurology exercises a powerful force on character development: There are shared patterns, there are important differences. The Asperger Plus Child presents a commonsensical, interesting, and understandable description of these essential distinctions..

Application of ''membrane-engineering'' to bioelectric recognition cell sensors for the ultra-sensitive detection of superoxide radical: A novel biosensor ... [An article from: Analytica Chimica Acta]
This digital document is a journal article from Analytica Chimica Acta, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
A new, hybrid type of ultra-sensitive electrophysiological superoxide anion (O"2?^-) sensor is described, which is based on ''membrane-engineered'' mammalian cells immobilized in an alginate matrix. The membrane-engineering process involved the electroinsertion of superoxide dismutase (SOD) molecules in the membranes of Vero fibroblast cells, which acted as catalytic units able to convert O"2?^- to H"2O"2. Superoxide dismutation triggered changes to the cell membrane potential that were measured by appropriate microelectrodes, according to the principle of the bioelectric recognition assay (BERA). The sensor instantly responded to O"2?^- with a detection limit (S/N=3) of 100pM. Combined with a 4-month storage capacity at room temperature, the novel biosensor principle offers new perspectives for monitoring ultra-low concentrations of free radical species and oxidative agents in biological systems. .

Sensitive and ultra-fast determination of arsenic(III) by gas-diffusion flow injection analysis with chemiluminescence detection [An article from: Analytica Chimica Acta]
This digital document is a journal article from Analytica Chimica Acta, published by Elsevier in 2007. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
A novel chemiluminescence gas-diffusion flow injection system for the determination of arsenic(III) in aqueous samples is described. The analytical procedure involves injection of arsenic(III) samples and standards into a 0.3molL^-^1 hydrochloric acid carrier stream which is merged with a reagent stream containing 0.2% (w/v) sodium borohydride and 0.015molL^-^1 sodium hydroxide. Arsine, generated in the combined carrier/reagent donor stream, diffuses across the hydrophobic Teflon membrane of the gas-diffusion cell into an argon acceptor stream and then reacts with ozone in the flow-through chemiluminescence measuring cell of the flow system. Under optimal conditions, the method is characterized by a wide linear calibration range from 0.6@mgL^-^1 to 25mgL^-^1, a detection limit of 0.6@mgL^-^1 and a sample throughput of 300 samples per hour at 25mgL^-^1 and 450 samples per hour at 25@mgL^-^1. .
