Yasha Gall, Julian Sorell Huxley, 1887-1975
Julian Sorell Huxley, 1887-1975 Yasha Gall Published by Nauka, St. Petersburg, Russia, 2004 Reproduced as an e-book with kind permission of Nauka Science editor: Academician AL Takhtajan Preface by the Science Editor The 20th century was the epoch of discovery in evolutionary biology, marked by many fundamental investigations. Of special significance were the works of AN Severtsov, SS Chetverikov, S Wright, JBS Haldane, G De Beer JS Huxley and R Goldschmidt. Among the general works on evolutionary theory, the one of greatest breadth was Julian Huxley’s book Evolution: The Modern Synthesis (1942). Huxley was one of the first to analyze the mechanisms of macro-evolutionary processes and discuss the evolutionary role of neoteny in terms of developmental genetics (the speed of gene action). Neoteny—the most important mechanism of heritable variation of ontogenesis—has great macro-evolutionary consequences. A Russian translation of Huxley’s book on evolution was prepared for publication by Professor VV Alpatov. The manuscript of the translation had already been sent to production when the August session of the VASKNIL in 1948 burst forth—a destructive moment in the history of biology in our country. The publication was halted, and the manuscript disappeared. I remember well a meeting with Huxley in 1945 in Moscow and Leningrad during the celebratory jubilee at the Academy of Sciences. He was deeply disturbed by the “blossoming” of Lysenkoist obscurantism in biology. It is also important to note that in the 1950s Huxley developed original concepts for controlling the birth rate of the Earth’s population. He openly declared the necessity of forming an international institute at the United Nations, since the global ecosystem already could not sustain the pressure of human “activity” and, together with humanity, might itself die. -

Abstract Computational neurobiology was born over half a century ago, and has since been consistently at the forefront of modelling in biology. The recent progress of computing power and distributed computing allows the building of models spanning several scales, from the synapse to the brain. Initially focused on electrical processes, the simulation of neuronal function now encompasses signalling pathways and ion diffusion. The flow of quantitative data generated by the "omics" approaches, alongside the progress of live imaging, allows the development of models that will also include gene regulatory networks, protein movements and cellular remodelling. A systems biology of brain functions and disorders can now be envisioned. As it did for the last half century, neuroscience can drive forward the field of systems biology. 1 Modelling nervous function, an ancient quest To accurately model neuronal function presents many Neurosciences have a long and successful tradition of challenges, and stretches the techniques and resources of quantitative modelling, where theory and experiment computational biology to their limits. -

Detail the functions of the muscle system. 3. Correctly label the parts of a myocyte (muscle cell) 4. Identify the levels of organization in a skeletal muscle from organ to myosin. 5. Explain how a muscle contracts utilizing the correct terminology of the sliding filament theory. 6. Contrast and compare cardiac and smooth muscle with skeletal muscle. Major Functions: Muscle System 1. Moving the skeletal system and posture. 2. Passing food through the digestive system & constriction of other internal organs. 3. Production of body heat. 4. Pumping the blood throughout the body. 5. Communication - writing and verbal Specialized Cells (Myocytes) ~ Contractile Cells Can shorten along one or more planes because of specialized cell membrane (sarcolemma) and specialized cytoskeleton. Specialized Structures found in Myocytes Sarcolemma: The cell membrane of a muscle cell Transverse tubule: a tubular invagination of the sarcolemma of skeletal or cardiac muscle fibers that surrounds myofibrils; involved in transmitting the action potential from the sarcolemma to the interior of the myofibril. Sarcoplasmic Reticulum: The special type of smooth endoplasmic Myofibrils: reticulum found in smooth and a contractile fibril of skeletal muscle, composed striated muscle fibers whose function mainly of actin and myosin is to store and release calcium ions. Multiple Nuclei (skeletal) & many mitochondria Skeletal Muscle - Microscopic Anatomy A whole skeletal muscle (such as the biceps brachii) is considered an organ of the muscular system. Each organ consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. -

TOM BROWN’S SCHOOLDAYS: DISCOVERING A VICTORIAN HEADMASTER IN RUGBY PUBLIC SCHOOL * CORTÉS GRANELL , Ana María Universitat de València Departament de Filologia Anglesa i Alemanya [email protected] Fecha de recepción: 11 de julio de 2013 Fecha de aceptación: 27 de julio de 2013 Título: Los días de escuela de Tom Brown: Descubriendo a un director victoriano en la Escuela Pública Rugby Resumen: Este artículo presenta la hipótesis que Thomas Arnold (1795-1842) mejoró y modeló al niño inglés medio para el Imperio Británico mientras que desempeñaba la función de director en la escuela pública Rugby (1828-1842). El estudio comienza por la introducción de la escuela pública en cuanto a su evolución y causas, además del nacimiento del mito de Arnold. La novela Tom Brown’s Schooldays de Thomas Hughes sirve para desarrollar nuestro entendimiento de lo genuino inglés a través del examen de una escuela pública modelo y sus constituyentes. Hemos realizado un análisis del personaje de Thomas Arnold mediante la comparación de un estudio de caso a partir de la novela de Hughes y dos películas adaptadas por Robert Stevenson (1940) y David Moore (2005). En las conclusiones ofrecemos la tesis que Thomas Arnold sólo pudo inculcar sus ideas por medio del antiguo sistema de los prefectos. Palabras clave: escuela pública, Rugby, Thomas Arnold, Thomas Hughes, inglés, prefecto. * This article was submitted for the subject Bachelor’s Degree Final Dissertation, and was supervised by Dr Laura Monrós Gaspar, lecturer in English Literature at the English and German Studies Department at the Universitat de València.

His letter to Orwell after the younger man sent him a copy of seems touchy The non-fiction work Brave New World Revisited , published in , is a fascinating work in which Huxley uses his tremendous knowledge of human relations to compare the modern-day world with his prophetic fantasy envisioned in Brave New World , including the threats to humanity, such as over-population, propaganda, and chemical persuasion. That's the tragedy of Brave New World Amazing thing being, Huxley extrapolated the contents of this entire book just from a single TV interview which he gave being disillusioned about how his fantasy can easily get real soon. He is unusually short for an Alpha; an alleged accident with alcohol in Bernard's blood- surrogate before his decanting has left him slightly stunted. My own belief is that the ruling oligarchy will find less arduous and wasteful ways of governing and of satisfying its lust for power, and these ways will resemble those which I described in Brave New World'. -
Brave New World: the Correlation of Social Order and the Process Of
Brave New World: The Correlation of Social Order and the Process of Literary Translation by Maria Reinhard A thesis presented to the University of Waterloo in fulfilment of the thesis requirement for the degree of Master of Arts in German Waterloo, Ontario, Canada, 2008 ! Maria Reinhard 2008 Author's Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract This comparative analysis of four different German-language versions of Aldous Huxley’s Brave New World (1932) shows the correlation between political and socio- cultural circumstances, as well as ideological differences, and translations of the novel. The first German translation was created by Herberth E. Herlitschka in 1932, entitled Welt – Wohin? Two further versions of it were released in 1950 and 1981. In 1978, the East German publisher Das Neue Berlin published a new translation created by Eva Walch, entitled Schöne neue Welt. My thesis focuses on the first translations by both Herlitschka and Walch, but takes into account the others as well. The methodological basis is Heidemarie Salevsky’s tripartite model. With its focus on author and work, commissioning institution and translator, it was developed as a tool to determine the factors influencing the process of literary translation. Within this framework, the translations are contextualized within the cultural and political circumstances of the Weimar and German Democratic Republics, including an historical overview of the two main publishers, Insel and Das Neue Berlin. -
