Copper as a Powerful Catalyst in the Direct Alkynylation of Azoles,

ANGEWANDTE CHEMIE, Issue 50 2009
François Besselièvre
Eine reizvolle Alternative: Die direkte Alkinylierung von Azolen durch kupfergestützte C-H-Aktivierung mit Alkinylbromiden als Kupplungspartner ist eine sehr rasche und funktionelle Gruppen tolerierende Methode, und sie eröffnet einen einfachen Zugang zu einer Vielzahl an Alkinylheterocyclen, der komplementär zur Sonogashira-Reaktion ist.

Highly Efficient Cyanosilylation of Sterically Bulky Ketones Catalyzed by Tin Ion-Exchanged Montmorillonite

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 4 2009
Jiacheng Wang
Abstract Tin ion-exchanged montmorillonite (Sn-Mont) was found to be a powerful catalyst for the cyanosilylation of aromatic and aliphatic ketones having a carbonyl group in sterically congested circumstances with cyanotrimethylsilane, giving the corresponding cyanohydrin trimethylsilyl ethers in excellent yields.

Sharing culture or selling out?

AMERICAN ETHNOLOGIST, Issue 3 2008
Developing the commodified persona in the heritage industry
ABSTRACT Native American professionals in the heritage industry often describe their work as "sharing culture" when they are involved in processes of transforming features of their cultures into alienable products for consumption. Participation in the heritage industry can be a powerful catalyst for local cultural reproduction, but it also poses a danger to those aspects of culture that Natives consciously protect from commodification. Drawing from a case study of a Native American,owned cultural-tourism business in Alaska, I explore the ways that tourism workers respond to this threat through the construction of what I call a "commodified persona."[cultural commodification, representation, Northwest Coast, tourism] [source]

Statistics-driven Development of OBD Systems: An Overview

QUALITY AND RELIABILITY ENGINEERING INTERNATIONAL, Issue 6 2006
Stefano Barone
Abstract Automotive on-board diagnostic (OBD) systems are designed to keep critical components under control during vehicle functioning, and to alert the driver in case of severe malfunctions. OBD systems aimed at reducing polluting emissions are mandatory on new motor vehicles. Some research projects conducted in cooperation between universities and the automotive industry have been quite successful in terms of knowledge advancement and industrial gain. An updated overview of the adopted methodologies and results obtained are given in this article. Such results can be valuable for both theorists and practitioners, since they witness the use of statistics as a powerful catalyst of technical progress, and give a possible line of action for further application in several scientific fields.
