Book excerpt: Même s'ils ont été moins étudiés, les ferrites sont sensibles à la rupture différée dans le temps. Le processus de fissuration lente est caractérisé par une vitesse de propagation de fissure V qui augmente avec le niveau de chargement appliqué KI, De plus, la fissuration lente caractérisée par des courbes V-K est dépendante de la microstructure, notamment de la taille de grain, voire de la présence de défauts comme des porosités aux points triples. Les ferrites auxquels nous nous intéressons possèdent une microstructure hétérogène vis à vis de la taille des grains, avec des pores aux points triples. Une telle microstructure conduit à une dispersion des mesures de fissuration lente V-K telle, qu’aucune prédictions fiables de durée de vie est possible à partir d'études expérimentales uniquement. Le recours à la simulation s'avère nécessaire à la fois pour élucider l'influence de la microstructure sur la rupture différée dans le temps et in fine pour estimer la durabilité du matériau. Nous avons développé une description locale de la fissuration lente, à l'échelle de la microstructure. Dans le cadre d'une méthodologie des zones cohésives, à partir des observations et descriptions physico-chimiques disponibles et de calculs atomistiques récents, nous proposons un modèle cohésif viscoplastique pour mimer le mécanisme de réaction-rupture responsable de la fissuration lente. La description permet d'estimer des variations V-K conformes aux observations. Dans les simulations de la rupture intergranulaire des polycristaux pour un chargement de fatigue statique, nous observons que l'avancée de la fissure est discontinue dans le temps avec des vitesses différentes selon l'orientation des grains. Le franchissement des points triples ralentit la progression de la fissure. Nous montrons qu'il est nécessaire de tenir compte des contraintes d'origine thermique pour prédire une influence de la taille des grains.

Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.

Available in PDF, EPUB and Kindle. Book excerpt: This is a path-breaking work as significant as the decipherment of Egyptian hieroglyphs by Champollion. For nearly130 years, the Indus script has remained a challenging enigma to scholars of languages, writing systems and civilization studies. The script was invented and used over an extensive area of what is called the Indus or Sindhu-Sarasvati civilization. Over 2000 or 80% of archaeological sites are found on the Sarasvati River basin, a river adored in a very old human document called the Rigveda and which dried up due to tectonic and resulting river migration causes. In 1822, history was made when Egyptian hieroglyphs were deciphered by Jean-Francois Champollion from parts of the Rosetta Stone. Champollion showed that the Egyptian writing system, c.3000 BCE was a combination of phonetic and ideographic glyphs. The Rosetta Stone is dated196 BCE and had a decree in three versions: one in ancient Egyptian hieroglyphs, one in the Egyptian demotic script, and one in ancient Greek. Since alphabets of ancient Greek were known, Champollion used the trilingual inscription to validate his historic decipherment. Indus Script Cipher makes history recording hundreds of hieroglyphs of India. Absence of a Rosetta Stone which has been the principal impediment in validating any decryption of Indus script cipher is thus overcome. Further validation comes from evidences of the historical periods in India from c. 600 BCE showing continued use of Indus script hieroglyphs which evolved from c. 3300 BCE. This book details a decipherment.of the Indus script using the same rebus method used by Champollion to read ancient phonetic hieroglyphs of Indiat. By demonstrating an Indian linguistic area of cultural and language contacts and history of language changes, this is a landmark contribution to civilization studies of the world and will promote efforts to rewrite the ancient socio-cultural and economic history of a billion people in India and neighboring regions.

Book excerpt: Fascinating vignettes about the men and woman who ruled PakistanWhat did Muhammad Ali Jinnah say when he received a royal salute from the last British regiment about to leave Pakistan? Did Ayub Khan consider turning Pakistan into a monarchy? Why was Yahya Khan so confident that the 1970 elections would return a hung parliament? What did Zulfikar Ali Bhutto say when the Pakistan Army launched a brutal crackdown in March 1971? How did Zia-ul-Haq get Bhutto to appoint him the army chief? In 2007, did Benazir Bhutto misread the extent of American support for her return to Pakistan? Had Pervez Musharraf and Nawaz Sharif agreed to a pull-out from Kargil even before the latter went to meet President Clinton in July 1999? Backed by meticulous research, the second book from Tilak Devasher, author of Pakistan: Courting the Abyss, provides enthralling insights into the lives and times of the leaders of Pakistan over the seven decades of the nation's existence. Anecdotal and engrossing, Pakistan: At the Helm presents a human side to the country's political history for anyone who is curious about the inner workings of its corridors of power.
