![]() Free Download Wei Wu, "A Centrifugal Particle Receiver for High-Temperature Solar Applications" English | ISBN: 3832538828 | 2015 | 195 pages | PDF | 9 MB The novel concept of a particle receiver for high-temperature concentrating solar applications was developed and investigated in the present work. The so-called Centrifugal Particle Receiver (CentRec) uses small bauxite particles as absorber, heat transfer and storage media at the same time. Due to advantageous optical and thermal properties, the particles can be heated up to 1000 degree Celsius without sintering in the storage. High thermal efficiencies at high outlet temperatures are expected indicating a promising way for cost reduction in solar power tower applications. A prototype in laboratory scale was designed, built and tested in order to demonstrate the feasibility and potential of the proposed concept. The expected simple control capability of the receiver could be verified and the target temperature of 900 degree Celsius successfully demonstrated. A thermal efficiency of >; 85 % is calculated by a validated corresponding numerical model for a particle outlet temperature of 900 degree Celsius and a design power of 1 MW/m^2. ![]() Free Download A Brilliant Life: My Mother's Inspiring True Story of Surviving the Holocaust by Rachelle Unreich English | November 28, 2023 | ISBN: 0063328755 | 304 pages | PDF | 3.00 Mb The powerful, true story of a Holocaust survivor told by her daughter-a tale that reminds us of the resilience of the soul and the ability of the heart to heal. ![]() Free Download A Bridge to Advanced Mathematics (Sally: Pure and Applied Undergraduate Texts) by Sebastian M. Cioabă, Werner Linde English | December 21, 2022 | ISBN: 1470471485 | 525 pages | PDF | 9.06 Mb Most introduction to proofs textbooks focus on the structure of rigorous mathematical language and only use mathematical topics incidentally as illustrations and exercises. In contrast, this book gives students practice in proof writing while simultaneously providing a rigorous introduction to number systems and their properties. Understanding the properties of these systems is necessary throughout higher mathematics. The book is an ideal introduction to mathematical reasoning and proof techniques, building on familiar content to ensure comprehension of more advanced topics in abstract algebra and real analysis with over 700 exercises as well as many examples throughout. Readers will learn and practice writing proofs related to new abstract concepts while learning new mathematical content. The first task is analogous to practicing soccer while the second is akin to playing soccer in a real match. The authors believe that all students should practice and play mathematics. The book is written for students who already have some familiarity with formal proof writing but would like to have some extra preparation before taking higher mathematics courses like abstract algebra and real analysis. ![]() Free Download Jan Bucerius, Hans-Jürgen Biersack, "99mTc-Sestamibi: Clinical Applications" English | 2011 | pages: 203 | ISBN: 3642042325, 3662519593 | PDF | 3,1 mb 99mTc-sestamibi is a single-photon emission computed tomography (SPECT) radiotracer that is widely used for the imaging of myocardial perfusion, as well as a variety of malignant and benign diseases. 99mTc-Sestamibi - Clinical Applications provides a detailed and informative overview of almost all the oncologic and non-oncologic applications of 99mTc-sestamibi SPECT, including several relatively rare indications. Different disease-related protocols for 99mTc-sestamibi SPECT are presented, and for each disease a comprehensive summary of the relevant pathology and epidemiology is provided. Throughout, there is a strong emphasis on the practical aspects of use of this popular tracer, including instructions for the preparation of several commercially available tracer kits. Clinical practitioners will find this book to be an invaluable guide to the application and benefits of 99mTc-sestamibi SPECT in both the inpatient and the outpatient setting. ![]() Free Download Emmet Purcell, "99 Reasons Everyone Hates Facebook" English | 2013 | ASIN: B00CSX7942 | EPUB | pages: 141 | 0.3 mb Despite boasting over one billion worldwide users, Facebook has inevitably transformed from being a well-loved social outlet for friends and family to an ego-centric, duck pose-laden, virtual farming-centric nightmare. Rather than wag a disapproving finger at the website itself, writer Emmet Purcell catalogs the 99 reasons why - despite our best efforts to leave - Facebook has become a part of our social identity, for good or ill.
