Meningiomas From Diagnosis to Treatment

Meningiomas From Diagnosis to Treatment
English | 2022 | ISBN: 1685077153, 978-1685077150 | 194 pages | True PDF | 19.75 MB
Meningiomas are among the most common primary tumors of the central neoplasm and are probably the most common primary nonglial tumor type. They are also the most common of the extra-axial tumors of the brain. Understanding of meningiomas and their classification, grading and molecular biology and genetics has evolved significantly over the past few decades. Environmental and genetic factors have been implicated in the development of these neoplasms. They arise from meningothelial (arachnoidal cap cells), typically situated in the meninges, near the dura. However, these cells can be found in other locations less commonly which accounts for the development of meningiomas in unusual locations (sometimes outside the central nervous system). Although the majority of these tumors are considered low grade neoplasms, classification and grading schemas have identified subtypes of meningiomas that are associated with more aggressive behavior or have unusual presentations. The fourteen chapters in this book address some of these various aspects of this diverse group of tumors.

Medieval Song from Aristotle to Opera

Medieval Song from Aristotle to Opera
English | 2022 | ISBN: 1501763881 | 293 pages | True PDF | 9.06 MB
Focusing on songs by the troubadours and trouvères from the twelfth to the fourteenth centuries, Medieval Song from Aristotle to Opera contends that song is not best analyzed as "words plus music" but rather as a distinctive way of sounding words . Rather than situating them in their immediate period, Sarah Kay fruitfully listens for and traces crosscurrents between medieval French and Occitan songs and both earlier poetry and much later opera. Reflecting on a song's songlike quality—as, for example, the sound of light in the dawn sky, as breathed by beasts, as sirenlike in its perils—Kay reimagines the diversity of songs from this period, which include inset lyrics in medieval French narratives and the works of Guillaume de Machaut, as works that are as much desired and imagined as they are actually sung and heard.

Maximum Power Point Tracking Background, Implementation and Classification

Maximum Power Point Tracking Background, Implementation and Classification
English | 2020 | ISBN: 1536181641 | 191 pages | True PDF | 12.88 MB
Maximum Power Point Tracking: Background, Implementation and Classification presents state-of-art of existing conventional maximum power point techniques, along with shading mitigation techniques, and compares them on various parameters. Photovoltaic systems include storage batteries when there is surplus power to provide electricity on demand. A suitable charge controller is needed for interfacing the solar photovoltaic module(s) with the battery bank. As such, attention has been made to attribute more features to the controller which will enhance the efficiency and controllability, and to monitor the health of the battery being charged. The authors review the considerations for maximum power point tracking in large utility scale photovoltaic systems and small-scale residential photovoltaic systems. A set of characteristics is proposed and criteria is defined to evaluate the suitability of a technique. In the penultimate study, power storage systems in ~100 W level are developed, which consist of direct current-alternating current converters, spherical Si solar cells, a maximum power point tracking controller, and lithium-ion batteries. Two types of inverters were used: SiC metal-oxide-semiconductor field-effect transistors (MOSFETs) and conventional Si MOSFETs. In closing, the authors propose a simplified control stratagem to offer optimal power output power from a variable speed grid connected wind energy conversion system.

Looking for a Perfect World Empirical and Applied Lines

Looking for a Perfect World Empirical and Applied Lines
English | 2022 | ISBN: 1685076254, 978-1685076252 | 312 pages | True PDF | 41.9 MB
The vision of perfectionism as a multidimensional variable has gained weight in scientific evidence as social functioning sets more rigorous performance standards of an individual or group differentiation in any field (e.g., academic, sports, work, social, religious...). There is a need to establish how we achieve the goals we set ourselves in any field of action, thanks mainly to the creation of valid and reliable instruments to measure it. In today's societies, there is an increasing emphasis on how to respond to the demands of the environment as quickly as possible, being effective and achieving the best results. The demands of the environment make it possible to stimulate contextually (if they are seen as traits) and to construct perfectionist patterns and attitudes (if they are understood as learned cognitions or behaviors), which are usually associated with agonizing feelings of devaluation, incapacity or psychological vulnerability. Perfectionists are characterized by setting their goals too high as they are always on a quest to do things perfectly. In cases where they cannot do something perfectly, they do not even try, or they live with significant suffering that floods their lives, causing feelings of dissatisfaction and affecting their self-esteem, mainly because their attention is reduced to focusing only on the end of the tasks they perform, leaving the development of the task in the background. People who seek to do things perfectly are rigid when it comes to carrying them out, causing difficulty in adapting to changes, and preventing them from enjoying the present moment or taking advantage of their mistakes to improve themselves. It is impossible to make everything perfect, as all people make mistakes, but perfectionists conceive failure as an expression of their maladjustment and for this reason, they generate high levels of anxiety, becoming people who try to control everything around them.

Loaded Language and the Dilemma of Journalism

Loaded Language and the Dilemma of Journalism
English | 2022 | ISBN: 1685077072, 978-1685077075 | 310 pages | True PDF | 12.61 MB
The problems of loaded language in journalism have eroded professional credibility over the years, and yet the journalist has a bounty of empirical and psychological tools to counter disinformation and propaganda by the use of the word alone. What are the best practices for investigative journalists to interview and present information in an emotionally literate manner? How and why is loaded language used, and how can a reporter counter attempts at gaslighting and manipulation? How does the profession reinvent the interview to connect to audiences through multiple literacies? Drawing from studies in the social sciences, this definitive book looks at the primal, emotional, and analytical aspects of words and their neurobiological effect on audiences, as it shows how to avoid loaded language, spin, propaganda, atmosphere, narrative, and sophistry.
