Le programme de conception optique ZEMAX a t utilis pour concevoir, optimiser et r pondre au crit re cibl du syst me optique IR qui consiste en 3 lentilles en germanium et une seule surface asph rique. L'alliage d'aluminium 6061 a t utilis pour fabriquer le bo tier m canique permettant d'assembler (transporter et aligner) le syst me optique avec le module de d tection thermique et de construire une cam ra thermique portable simple. Le logiciel MATLAB a t utilis pour cr er un programme de traitement des images thermiques sur PC afin de convertir les images thermiques (grises) en images couleur flash et de lire la temp rature de l'objet partir de son image.

In the current age of science and technology, our lives have become dominated by countless scientific and technological innovations without which the earth would be a much poorer place. Life as we know would become absolutely bleak and boring without the inventions and advances being made all over the globe. In fact, scientific inventions, discoveries and innovations have ushered in a dramatic revolution in virtually every sphere of life. But at the same time, the skewed use of technology is at loggerheads with the environment. We, and our environment, now face a number of critical challenges and it is in response to this that we wrote this book to raise awareness for environmental issues and related management aspects. With a primary focus on Environmental Management – the rational reconciliation of man and nature, which involves the judicious exploitation and utilization of natural resources without disturbing the ecosystem’s balance – it will thus help toimprove the relationship between man and environment. Moreover, it offers a wealth of ready-to-use material for advanced undergraduate and graduate students of Environment and Water Management. The book systematically addresses a range of key aspects, e.g. scientific principles, methods and ideas, as well as life-long learning skills for students. Further, it provides a solid foundation for applying scientific approaches to environmental problems.

Le carcinome thyro dien est la tumeur maligne endocrinienne la plus r pandue et repr sente 2 % de tous les cancers humains. Nous avons analys l'exon 15 du g ne BRAF et les exons 1 et 2 des g nes RAS dans soixante (60) chantillons cons cutifs de tissu thyro dien (tumeur et tissus normaux adjacents). Les mutations globales de BRAF se sont r v l es tre 25% (15 sur 60) affectant le codon 600 (valine glutamine) et limit es uniquement au cancer papillaire de la thyro de, mais d pourvues de toute mutation de RAS. Nous avons analys 140 chantillons de sang de patients atteints de cancer de la thyro de la recherche du polymorphisme HRAS T81C et RET, en comparaison avec 170 t moins exempts de cancer. Le g ne TSHR s'est r v l hyperm thyl dans 25 % (15 sur 60) des cas, avec une forte association avec des niveaux lev s de TSH. Nous concluons que les v nements mutationnels ainsi que la surexpression du g ne BRAF sont fortement impliqu s dans la pathogen se du cancer de la thyro de et que la surexpression de la prot ine BRAF est ind pendante du statut mutationnel de BRAF. Les polymorphismes HRAS T81C et RET augmentent mod r ment le risque de cancer de la thyro de. Notre tude a montr une forte implication de la m thylation du g ne TSHR et son association significative avec la mutation BRAF V600E dans les tumeurs thyro diennes, d crivant une connexion positive entre la voie TSHR et la voie MAP Kinase.

O carcinoma da tir ide a neoplasia maligna end crina mais prevalente e representa 2% de todos os cancros humanos. Analis mos o ex o 15 do gene BRAF e os ex es 1 e 2 dos genes RAS em sessenta (60) amostras consecutivas de tecido da tir ide (tumor e tecido normal adjacente). No geral, foram encontradas muta es no BRAF em 25% (15 de 60) dos casos, afetando o c don 600 (valina para glutamina) e restritas apenas ao cancro papilar da tir ide, mas sem qualquer muta o no RAS. Analis mos 140 amostras de sangue de pacientes com cancro da tir ide para HRAS T81C e polimorfismo RET em compara o com 170 controles sem cancro. O gene TSHR foi encontrado hipermetilado em 25% (15 de 60) dos casos, com forte associa o com n veis elevados de TSH. Conclu mos que tanto os eventos mutacionais quanto a superexpress o do gene BRAF est o altamente implicados na patog nese do cancro da tir ide e que a superexpress o da prote na BRAF independente do estado mutacional do BRAF. Os polimorfismos HRAS T81C e RET aumentam moderadamente o risco de cancro da tir ide. O nosso estudo mostrou uma alta implica o da metila o do gene TSHR e sua associa o significativa com a muta o BRAF V600E em tumores da tir ide, retratando uma conex o positiva entre a via TSHR e a via MAP Kinase.
