This, Herve

The authors wish to thank Herve Borrion for assistance in compiling this chapter into DI X. We also recognise the contributions made by a number of students and in particular, Ioannis Papoutsis and Daniel O Hagan. 

We express our thanks to the students with whom we have worked on these subjects and whose results we have used, in particular Herve Borrion, Shirley Coetzee and Michele Vespe, and to the organisations, including the UK Ministry of Defence, the US Air Force Office of Scientific Research, the UK Engineering and Physical Sciences Research Council, QinetiQ and its predecessors, BAE SYSTEMS, Thales Sensors and AMS, who have supported the various projects. We also thank Erik De Witte and Herve Borrion for their help in rendering this document into DTj X. 

This chapter is dedicated to the memory of Prof. Herve Allain who died on November 2006. Herve cowrote this chapter for the first edition of this book. We miss him a lot. 

In Barcelona in 1323, Herve Nedelic, General of the Dominican Friars, pronounced the penalty of excommunication against all clericals who should apply themselves to the study of alchemy or should not within eight days burn all books of that character which might be in their hands. Haureau2 considers this as circumstantial evidence that the alchemical treatises attributed to St. Thomas Aquinas were not yet issued, a conclusion in harmony with all known facts, for no allusions to any of these works are known until much later. 

We thank Dr. Herve Masson for helpful discussions and Dr. Jocelyne Gasteau for her help with the translation of this manuscript. 

Finally it is time to ask the most important questions of all. Who devoted so much time and effort to study these questions in so much detail These are enthusiastic amateurs, adventure-cooks and cmious experts who are fans of the scientific field now called molecular gastronomy. This term was coined by Hungarian-born physicist Nicholas Kurti (1908-1998, bomKiirti Miklos), who was an expert in low temperature physics at the University of Oxford and had food science as a hobby. The methods were further developed and popularized by French chemist Herve This (pronounced Tis). Today, noted Catalan and French chefs Ferran Adria and Pierre Gagnaire prepare surprisingly diverse dishes using the principles of molecular gastronomy. 

The scientific method is spilling over into restaurant kitchens. Chefs are controlling for variables and keeping records in order to develop foods that are a surprise and a delight to the senses. This new field is known as molecular gastronomy and was founded by chemist and chef Herve This from the French National Institute for Agricultural Research in Paris and the late physicist Nicholas Kurti. 

Erythrocyte transketolase activity was found to be lowered in different groups of TD patients (Herve et al. 1995 Khounnorath et al. 2011) (Table 33.2). However, post mortem brains of alcoholics who died without symptoms of Wernicke s encephalopathy (WE) revealed 20-35% reductions in the activities of all TDP-dependent enzymes in various brain regions (Lavoie and Butterworth 1995). This means that some degree of TD-induced reductions in oxidative metabolism may be tolerated. In fact, individual sensitivity to TDP deficits may be modified by coexisting clinical conditions such as alcoholism, renal insufficiency, dialysis programmes, aging, diabetes, cardiovascular complications, and voluntary or socio-economically dependent dietary habits (Tables 33.1 and 33.2). 

The method of determining T via amplitude modulation of Hi relies on variation of the modulation frequency, denoted by QJIti, until it exceeds T), at which point the magnetization cannot respond to the power variation and there is a loss in the detected EPR signal amplitude (Herve Pescia, 1960a). In a sense, this Ti measurement is analogous to that used to analyze the impedance of a nonlinear system, sueh as a passive filter. The precept is that the response of a system y t) to some perturbation x t) is determined by some differential equation of order n. In the case of a linear system and perturbation x(t)=A sin((oO, one observes a response y(t)=B sin(co -l-(t)) and one defines a transfer function as the ratio of output to input (in the frequency domain) H(j( i)= H(( i) wherey((o) and x(co)...
