Cosmic Heritage: Evolution from the Big Bang to Conscious Life
No full textThis book follows the evolutionary trail all the way from the Big Bang 13.7 billion years ago to conscious life today. It is an accessible introductory book written for the interested layperson – anyone interested in the ‘big picture’ coming from modern science. It covers a wide range of topics including the origin and evolution of our universe, the nature and origin of life, the evolution of life including questions of birth and death, the evolution of cognition, the nature of consciousness, the possibility of extraterrestrial life and the future of the universe. The book is written in a narrative style, as these topics are all parts of a single story. It concludes with a discussion on the nature and future of science. “Peter Shaver has written engagingly for anyone curious about the world we inhabit. If you'd like to know how the Universe began, where the chemical elements originated, how life may have started on Earth, how man, ants and bacteria are related to each other, or why we humans think, you will enjoy this panoramic book and its clear presentation” – Martin Harwit, Professor Emeritus of Astronomy, Cornell University, NY, and former Director of the Smithsonian National Air and Space Museum, Washington. "Who is not interested in the big questions "How did it all start? Where do we come from? Where do we go? Are we alone?" This book addresses theses questions in an entertaining way based on our knowledge of modern science. It opens our horizons towards understanding the history of the universe and the origin and evolution of life in the context of cosmic evolution." Dr. Gerda Horneck, DLR German Aerospace Center, Institute of Aerospace Medicine, Cologne, Germany. "A very elegant, open-minded book that opens the door for informed discussion of the continuity of evolutionary processes from the big bang to the emergence of the mind... stimulating and highly engaging reading" – Ryszard Maleszka, Professor of Molecular Genetics, Australian National University, Canberra. "Peter Shaver has produced a remarkable book. He covers an immense range, offering a splendid overview of the intricate processes that connect us to the universe, and which allowed complex life to emerge from simple beginnings" – Martin Rees, Master of Trinity College, Cambridge and Astronomer Royal. “Where did the universe come from? What is life and how did it begin? How did complex life-forms evolve? How did consciousness arise? Are we alone in the universe? Questions don't get any bigger than these. In this beautifully concise account, astrophysicist Peter Shaver asks these questions and more and assesses how far modern science has come to providing answers. Anyone who has ever wondered who we are and where we came from should read this book” – Stephen Simpson, Professor of Biological Sciences, University of Sydney. “This is a well written, marvellous book for a very broad audience which covers much of current scientific thought in a concise way. The author successfully shows how many of the great philosophical issues that have fascinated humanity for centuries from the origin of the world, the evolution of life to the nature of consciousness are gradually being shifted from the domain of philosophy or speculation to that of rigorous science.” – Lodewijk Woltjer, former Director General of the European Southern Observatory and former President of the International Astronomical Union.

El proceso de desarrollo abarco diversas etapas cruciales. Inicialmente se lleva a cabo un análisis tipológico exhaustivo de las afeitadoras desechables existente. Esta fase permitió establecer los requerimientos específicos que el mango biodegradable debía cumplir, para garantizar la eco eficiencia del producto. Se implementó la metodología del ecodiseño. A través de este enfoque, se incorporan criterios ambientales durante el proceso de fabricación del mango asegurando un enfoque sostenible y responsable. Además, se realiza el análisis del material mediante ensayos de tracción, compresión e impacto Charpy que proporcionaron información esencial sobre las propiedades y la idoneidad del material. Finalmente se realiza la evaluación del mango mediante pruebas funcionales realizadas por un grupo diversos de usuarios. Estas pruebas permitieron evaluar aspectos clave como el diseño, la ergonomía y la funcionalidad del mango de afeitar.The goal of this project is to desing and manufacture a prototype of a biodegradable shaver handle using corn cob as raw material. This innovative approach responds to the need to replace disposable shavers made with polymers, which contributes to the reduction of environmental pollution. Currently, the transformation of single-use products through the adoption of eco-friendly materials is a constantly growing trend. The development process encompasses several crucial stages. First, an exhaustive typological analysis of the existing disposable shavers is carried out. This phase allowed us to establish the specific requirements that the biodegradable handle had to meet, to guarantee the eco-efficiency of the product. The eco-design methodology was implemented. Through this approach, environmental criteria are incorporated during the handle manufacturing process ensuring a sustainable and responsible approach. In addition, material analysis is carried out using tensile, compression, and Charpy impact tests that provide essential information on the properties and suitability of the material. Finally, the evaluation of the handle is carried out through functional tests carried out by a diverse group of users. These tests allowed us to evaluate key aspects such as the design, ergonomics, and functionality of the shaver handle.PregradoIngeniero en Diseño Industria
Session 3-A: Longing in the Work of C.S. Lewis
No full textC.S. Lewis: Sixty Years of Letters: A Thematic Overview of His Passions - Jessica Shaver Renshaw
Rather than speaking about C.S. Lewis, we will let Jack speak about himself through his letters: what he loved, such as books, seasons/weather, walking tours, bathing, Ireland, animals, convalescence, Joy, and writing; what he loathed: writing letters, Americans, cities, TV, newspapers, movies, modern novels/poetry/theology; what he feared; what he didn\u27t understand; and what he regretted, as well as his descriptions of what he looked like, what he did well, what he did badly. I will force myself with Great Difficulty (because of all the choice bits I will have to leave out) to limit these tastes of his sixty-year three-volume, 3,600 page, 9-1/2 pound correspondence to what can be savored in twenty minutes!
\u27Parascriptural\u27 Revelation in C.S. Lewis - J.C. Calhoun
In the theology of C.S. Lewis, God is rather verbose and unrestrained in the manners and means of communication. God must be understood as the speaking God; anything less will not do Him justice. The few extant works about Lewis\u27s theology of revelation focus on scripture, and though this is an important topic, one cannot understand it properly without first understanding how God speaks in general. This paper explicates his epistemology as a foundation, and then under the rubric of basic communication theory (author, text, recipient, re-texting), presents eleven \u27parascriptural\u27 paths through which God speaks as mentioned in Lewis\u27s writings. The term \u27parascriptural\u27 - \u27para\u27 in the sense of \u27beside\u27 or \u27alongside of\u27 - is used instead of \u27General Revelation\u27 because the traditional division between General and Special Revelation forces categories upon Lewis that are alien to his thought. After presenting these eleven paths, they are categorized and related back to his epistemology. The paper then finishes as it should, with tantalizing questions about what this means for understanding Lewis and why it is important in our own lives.

Effects of feeding ISA brown and Shaver white layers breeder with sources of n-3 fatty acids on hatching eggs profile, apparent embryonic utilization of egg components and body composition of day-old chicks
No full textEffects of feeding ISA brown and Shaver white breeders sources of n-3 fatty acids (FA) on egg components, apparent embryonic utilization (AEU) of egg components, and hatching body composition were examined. A total of 240 female and 30 male per each strain were fed either: 1) Control (CON), 2) CON + 1 % of dried microalgae (DMA), as a source of docosahexaenoic acid or 3) CON + 2.60 % of dry extruded product consisting of full-fat flaxseed (FFF), as a source of α-linoleic acid for 30 days. Eggs were incubated, and the residual yolks (RY) sampled at hatch (DOH) for AEU of dry matter (DM), minerals, and organic matter (OM). Feeding n-3 FA sources reduced the AEU of OM and minerals resulting in a higher ratio of RY to body weight (P = 0.002). Feeding FFF increased body fat and decreased lean in Shaver white hatchlings compared with CON (PThe presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

“Reality – is it a horror?”: Richard Shaver's subterranean world and the displaced self
No full textThis paper discusses the works of author Richard S. Shaver, who rose to prominence in the science fiction world in the 1940s with stories describing a vast underworld of caverns under the surface of the earth. These caverns were inhabited by evil beings called “dero” that used high-tech devices to torment the inhabitants of the surface world. Shaver, who had spent several years in mental institutions prior to his writing career, claimed his stories were true, and Amazing’s editor, Raymond A. Palmer, aggressively promted the “Shaver Mystery.” This prompted a backlash from science fiction fandom against both Shaver and Palmer. This paper gives an overview of Shaver’s career and explores his world-system as a form of theodicy, drawing in particular on his novel Mandark, a retelling of portions of the Bible narrative. Shaver’s monsters and their devices are examples of an “influencing machine,” a commonly-occurring delusional phenomenon first described by psychologist Victor Tausk in 1919, an externalized force that a patient believes is the source of thoughts and sensations. This paper argues that, for Shaver, the dero provided a psychological framework for processing tragic and traumatic events, externalizing tormenting forces into monsters. His fiction then became a force for combatting those torments within a narrative context. Like other conspiracy theories, the Shaver Mystery seeks to impose order on a chaotic world
