The book is essentially a result of the authors' attempt to generalize Dirac's elegant method of solving the eigenvalue problem of the linear harmonic oscillator by constructing raising and lowering operators. As such, students of elementary Quantum Mechanics will find Chapters II and III quite useful and illuminating. At many stages in the book the reader will find the power of the commutator algebra unfolding in an elegant manner, as in the original Dirac approach. See the lucid application of the technique to find the eigenvalues and eigenfunctions of the Kratzer oscillator algebraically A student of Advanced Quantum Mechanics will find, in Chapter III, an illustrious application of the celebrated Infeld-Hull factorization method to find a class of ladder operators which connect the eigenstates of a hierarchy of Hamiltonians like, but not the same as, the ones in Supersymmetric Quantum Mechanics. The book will be of interest to a large spectrum of students of Physics at the Master's degree level and graduate students entering a research career in Theoretical Physics and Quantum Chemistry.
The objective of this study was to define age-related changes in the human smile. The areas of interest were: upper lip length at smile and repose, upper lip thickness at smile and repose, maxillary incisal display at smile, interlabial gap height at smile,smile index, percent buccal corridors, intercommissural width at rest, smile height, and smile arc.Video equipment was used to capture video for 150 subjects. Two frames for each subject were selected; one frame representing the lips at rest and the second representing the widest smile. After excluding 50 subjects the data for the remaining 100 subjects was analyzed with equal number of males and females.This study helps to establish age related dynamic changes. As the person ages the smile gets narrower vertically and wider transversely. The dynamic measures indicate that the muscles' ability to create a smile decreases with increasing age.

Jacob?s Ladder – A Story of Virginia During the War
Jacob?s Ladder – A Story of Virginia During the War
This charming story of the Jackson cricketing dynasty describes the adventures of Mike Jackson at boarding school as he makes his way up the sporting ladder to the first eleven. The young P. G. Wodehouse evokes the peaceful, prosperous world of middle-class England before the Great War, a place where rich men hire private cricket professionals to coach their sons at home, and little seems to matter at school except the publishing of team lists and the taking of tea. But such is the novelist's skill that he can make excitement from the small-scale dramas of teenage life, and interest even the most unsporting reader in the cricket matches he describes so lovingly. A curiosity for those who know only the Wodehouse of Blandings and Piccadilly, but a delightful one.
Who makes most money from the demand for cappuccinos early in the morning at Waterloo Station? Why is it impossible to get a foot on the property ladder? How does the Mafia make money from laundries when street gangs pushing drugs don't? Who really benefits from immigration? How can China, in just fifty years, go from the world's worst famine to one of the greatest economic revolutions of all time, lifting a million people out of poverty a month? Looking at familiar situations in unfamiliar ways, THE UNDERCOVER ECONOMIST is a fresh explanation of the fundamental principles of the modern economy, illuminated by examples from the streets of London to the booming skyscrapers of Shanghai to the sleepy canals of Bruges. Leaving behind textbook jargon and equations, Tim Harford will reveal the games of signals and negotiations, contests of strength and battles of wit that drive not only the economy at large but the everyday choices we make.
This investigation analyzed the efficacy of Arizona’s Career Ladder program by focusing on the effect of Career Ladder on student achievement. Ultimately, it is hoped that this study determined whether Career Ladder has an impact on student achievement, as measured by the Arizona Instrument to Measure Standards, Dual Purpose Assessment, and the Terra Nova assessment (embedded in the AIMS assessment). The results of this study could impact teacher incentive pay programs across the country as well as influence legislative decision regarding future funding of the Arizona Career Ladder Program.
Currently there is limited evidence supporting podiatric treatment of children with JIA. The foot orthoses (FOs) prescribed to JIA children so far appeared to be very expensive and required long time to manufacture before the fitting. This multicentre single-blinded randomised controlled trial (RCT) aimed to determine whether pre-formed FOs that can be prescribed at chair side, impacted on pain, quality of life (primary outcomes) and/or gait-parameters (secondary outcomes) in children affected by JIA. The results strongly suggest that FOs are effective in improving pain, quality of life and most gait parameters in JIA children. FOs can be customised at chair-side so JIA children can receive immediate podiatric benefit from the same day of the biomechanical assessment. Compliancy rate proved to be extremely high confirming that the podiatric treatment is well accepted by JIA children. Primary and secondary outcome’s results, strongly support the use of FOs in the treatment of JIA children, which highlights the important role of the podiatrists within the multidisciplinary team in paediatric rheumatology.
The main purpose of this book is to explore and analyze the unknown Chinese emotions hidden behind the movement “Yuanchangbu,” and to find out the meaning behind it from a cultural and historical viewpoint. We will rediscover some of the silences in history and restore the psychology, emotion and movement of Chinese classical dance. Therefore, this paper will, firstly, set “Yuanchangbu” as a clue through which to explore how the movement in daily life developed into the movement of Chinese classical dance. Furthermore, due to the impact of ancient Chinese foot binding culture on the formation of “Yuanchangbu”, this book, based on research of the movement, will also explore the era of foot binding. We will understand the changing progress of Chinese men and women’s lifestyle from the era of the natural-foot to foot binding. And at this moment trigger further thought on the culture and style of Chinese traditional dance by the “foot-binding culture.”
Diabetic foot disease is one of the most invalidating long-term complications of diabetes. Given the dramatically increasing prevalence of types 1 and 2 diabetes mellitus worldwide, the medical community must be prepared for the number of diabetic foot ulcers and lower extremity amputations that will follow this “epidemic” of diabetes. In recent years, the standards of diabetic foot care have improved considerably. However, despite the availability of new treatments, techniques, and advances in the medical and surgical care of people with diabetic foot disease, the incidence of lower extremity amputation in this population is still extremely high. A widening gap exists between our knowledge in the field and the daily experience and outcomes of patients in diabetic foot care centers. The good news is that it is possible to reduce amputation rates by up to 85%. The remaining question is “How do we do it?” This work summarizes the considerable effort made in the field of diabetic foot disease. Special emphasis is given to approaches dealing with the issue of the loss of protective pain sensations and its consequences, in terms of the development of at-risk zones under the foot.
