Book Memory Disorders in Psychiatric Practice

Download or read book Memory Disorders in Psychiatric Practice written by German E. Berrios and published by Cambridge University Press. This book was released on 2000-03-16 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Memory complaints are a frequent feature of psychiatric disorder, even in the absence of organic disease. In this practical reference for the clinician, first published in 2000, German Berrios and John Hodges lead an international team of eminent psychiatrists, behavioural neurologists and clinical psychologists to focus on the psychiatric and organic aspects of memory disorders from the perspective of the multidisciplinary memory clinic. These disorders include organic syndromes such as the dementias, the amnesic syndrome and transient amnestic states, and also psychiatric aspects of memory disorders in the functional psychoses. Among the specific topics reviewed are the paramnesias, conditions such as déjà vu, flashbulb and flashback memories, and the problems of recovered, false and feigned memories. Throwing light on established conditions, and also introducing two new syndromes, this book makes a major contribution to the understanding and clinical management of memory disorders in psychiatry, neuropsychology and other disciplines.

Download or read book Cryocoolers 13 written by Ronald G. Ross and published by Springer Science & Business Media. This book was released on 2007-02-15 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last two years have witnessed a continuation in the breakthrough shift toward pulse tube cryocoolers for long-life, high-reliability cryocooler applications. New this year are papers de scribing the development of very large pulse tube cryocoolers to provide up to 1500 watts of cooling for industrial applications such as cooling the superconducting magnets of Mag-lev trains, coolmg superconducting cables for the power mdustry, and liquefymg natural gas. Pulse tube coolers can be driven by several competing compressor technologies. One class of pulse tube coolers is referred to as "Stirling type" because they are based on the linear Oxford Stirling-cooler type compressor; these generally provide coolmg m the 30 to 100 K temperature range and operate ^t frequencies from 30 to 60 Hz. A second type of pulse tube cooler is the so-called "Gifford-McMahon type. " Pulse tube coolers of this type use a G-M type compressor and lower frequency operation (~1 Hz) to achieve temperatures in the 2 to 10 K temperature range. The third type of pulse tube cooler is driven by a thermoacoustic oscillator, a heat engine that functions well in remote environments where electricity is not readily available. All three types are described, and in total, nearly half of this proceedings covers new developments in the pulse tube arena. Complementing the work on low-temperature pulse tube and Gifford-McMahon cryocoolers is substantial continued progress on rare earth regenerator materials.

Book Bayesian Thinking in Biostatistics

Download or read book Bayesian Thinking in Biostatistics written by Gary L Rosner and published by CRC Press. This book was released on 2021-03-15 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: Praise for Bayesian Thinking in Biostatistics: "This thoroughly modern Bayesian book ...is a 'must have' as a textbook or a reference volume. Rosner, Laud and Johnson make the case for Bayesian approaches by melding clear exposition on methodology with serious attention to a broad array of illuminating applications. These are activated by excellent coverage of computing methods and provision of code. Their content on model assessment, robustness, data-analytic approaches and predictive assessments...are essential to valid practice. The numerous exercises and professional advice make the book ideal as a text for an intermediate-level course..." -Thomas Louis, Johns Hopkins University "The book introduces all the important topics that one would usually cover in a beginning graduate level class on Bayesian biostatistics. The careful introduction of the Bayesian viewpoint and the mechanics of implementing Bayesian inference in the early chapters makes it a complete self- contained introduction to Bayesian inference for biomedical problems....Another great feature for using this book as a textbook is the inclusion of extensive problem sets, going well beyond construed and simple problems. Many exercises consider real data and studies, providing very useful examples in addition to serving as problems." - Peter Mueller, University of Texas With a focus on incorporating sensible prior distributions and discussions on many recent developments in Bayesian methodologies, Bayesian Thinking in Biostatistics considers statistical issues in biomedical research. The book emphasizes greater collaboration between biostatisticians and biomedical researchers. The text includes an overview of Bayesian statistics, a discussion of many of the methods biostatisticians frequently use, such as rates and proportions, regression models, clinical trial design, and methods for evaluating diagnostic tests. Key Features Applies a Bayesian perspective to applications in biomedical science Highlights advances in clinical trial design Goes beyond standard statistical models in the book by introducing Bayesian nonparametric methods and illustrating their uses in data analysis Emphasizes estimation of biomedically relevant quantities and assessment of the uncertainty in this estimation Provides programs in the BUGS language, with variants for JAGS and Stan, that one can use or adapt for one's own research The intended audience includes graduate students in biostatistics, epidemiology, and biomedical researchers, in general Authors Gary L. Rosner is the Eli Kennerly Marshall, Jr., Professor of Oncology at the Johns Hopkins School of Medicine and Professor of Biostatistics at the Johns Hopkins Bloomberg School of Public Health.

Book EASY GUIDE TO ARABIC GRAMMAR FOR UNDERSTANDING QURAN AND HADITH

Download or read book EASY GUIDE TO ARABIC GRAMMAR FOR UNDERSTANDING QURAN AND HADITH written by Abo Othman Kharisman and published by Pustaka Hudaya. This book was released on 2023-04-11 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Muslims, we have the desire to have a proper understanding of the Quran and the hadiths of the Prophet. To understand the Quran we need the explanations of the Olama (Islamic scholars) in their interpretations. Likewise, to understand the hadiths of the Prophet, we need to study the sharh (explanations) of the Olama. If we want to understand the explanations of the Olama, we need to equip ourselves with proper skills in the Arabic language. Only then we can understand the structure of Arabic in the fields of Nahwu and Shorof (Tashrif). This book is meant as a guide to equip readers with basic passive Arabic skills to understand Arabic with the help of a dictionary. Hopefully, it can be a useful starting point in developing Arabic language skills. The main references referred to in this book include matn al-Ajurrumiyyah with its syarh, such as the syarh of Shaykh Ibn Uthaimin and also al-Mumti' by Malik bin Salim bin Mathor al-Mahdzariy who was taqdim Shaykh Muqbil bin Hadi al-Wadi'iy (rahimahullah). Likewise, the book Durusul Lughoh al-Arobiyyah by Dr. V. Abdurrahim, with his syarh by Husain bin Ahmad bin Abdillah Aalu Ali. Not to forget al-Amthilatut Tashrifiyyah who was commanded by the Minister of Religion of the Republic of Indonesia, Mr. Saifuddin Zuhri. This book provides many examples in the form of sentences taken from verses of the Quran, corresponding with what is being discussed in the lessons. We also used hadiths of the Prophet sallallaahu 'alaihi wasallam and sayings of the Ulama of Ahlussunnah taken from their literature. In most of the chapters, there are exercises in the form of questions to practice. This includes exercises in translating non-characterized Arabic writings. Sometimes we added a mini dictionary to facilitate the completion of the tasks. This book originally printed in Indonesian language as title “Panduan Mudah Memahami Bahasa Arab (Dasar-dasar Ilmu Nahwu dan Tashrif”. Then, translated into English by Abo Abdil Aziz Obaid al-Holandiy. Jazaahullaahu khayran. May be some transliteration in this book still in Indonesian style.
