What do children need to flourish? : Conceptualizing and measuring indicators of positive development
Regardless of its validity, many adults share a belief that today’s youth face an inauspicious future. Drugs, sex, violence, disintegration of the nuclear family, technology that replaces interpersonal relationships—that’s what you hear in the news. The media, through its dramatization of the dangers and risks children confront and pose, have created a well-established image of disenfranchised, hostile, and often-destructive children and adolescents. This image ignores the many children who are thriving as well as the possibility of positive outcomes for children and youth.
Well Logging for Earth Scientists
Well logging lies at the intersection of applied geophysics, petroleum and geotechnical engineering. It has its roots in the tentative electrical measurements in well bores which were made by the Schlumberger brothers some 80 years ago in the earliest days of systematic petroleum exploration. Today, a variety of specialized instruments is used to obtain measurements from the borehole during, as well as after, the drilling process. This readable and authoritative treatment of the physics of these measurements dispels the "black magic" of well log interpretation by relating them, including those obtained by the latest generation of tools, to rock physics. It offers a thorough exposé of the physical basis of borehole geophysical measurements, as well as an introduction to practical petrophysics -- extracting desired properties from well log measurements.

This book presents in an interdisciplinary manner experts' analyses.and views of existing verification systems: It gives guidelines and advice for the improvement of those systems as well as for new challenges in the field.
Uranium in the Environment : Mining Impact and Consequences
Uranium is an element to be found ubiquitous in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds µg/l without impact from mining, nuclear industry, and fertilizers. Considering the WHO recommendation for drinking water of 15 µg/l (has been as low as 2 µg/l before) due to the chemical toxicity of uranium the element uranium has become an important issue in environmental research. Besides natural enrichment of uranium in aquifers uranium mining and milling activities, further uranium processing to nuclear fuel, emissions form burning coal and oil, and the application of uranium containing phosphate fertilizers may enrich the natural uranium concentrations in soil and water by far.
Uniformly Accelerating Charged Particles : A Threat to the Equivalence Principle
There has been a long debate about whether uniformly accelerated charges should radiate electromagnetic energy and how one should describe their worldline through a flat spacetime, i.e., whether the Lorentz-Dirac equation is right. There are related questions in curved spacetimes, e.g., do different varieties of equivalence principle apply to charged particles, and can a static charge in a static spacetime radiate electromagnetic energy? The problems with the LD equation in flat spacetime are spelt out in some detail here, and its extension to curved spacetime is discussed. Different equivalence principles are compared and some vindicated. The key papers are discussed in detail and many of their conclusions are significantly revised by the present solution.

Further, point-contact and tunnelling spectroscopy and Josephson experiments are addressed.
Two Cultures : Essays in Honour of David Speiser
Editor Kim Williams has assembled a group of notes where scholars contribute essays inspired by their contact with Prof David Speiser. In honour of his eightieth birthday. Topics range from history of sciences to history of art, from architecture theory to music theory, from particle physics to the proliferation of nuclear weapons, to an essay on the very nature of interdisciplinary studies.
Tumeurs endocrines thoraciques et digestives = Thoracic and digestive endocrine tumors
There is little literature on digestive and thoracic endocrine tumors. The complexity of their management, often entrusted to different specialists, the multiplicity of terminologies used to designate them, the diversity of their locations and their characterization explain this lack of work. A synthesis of clinical knowledge relating to these pathologies was therefore necessary; requirement reinforced by the arrival of new imaging techniques and new treatments. This book takes the gamble of a transversal approach to the study of these tumors while emphasizing their common characteristics; once the clinical and prognostic characteristics have been stated, the authors study the different therapeutic weapons.
Trapped Charged Particles and Fundamental Interactions
The development of ion traps has spurred significant experimental activities able to link measurable quantities to the most fundamental aspects of physics. The first chapter sets the scene and motivates the use of ion traps with an in-depth survey of the low-energy electroweak sector of the standard model amenable to precision test. The next parts then introduce and review aspects of the theory, simulation and experimental implementation of such traps. Last but not least, two important applications, namely high resolution mass spectrometry in Penning traps and tests of fundamental physics - such as the CPT theorem - with trapped antiprotons are discussed.
Towards a Cleaner Planet : Energy for the Future
The world has entered a period of significant changes regarding the future of energy generation, mainly caused by the apparent exhaustion of hyd- carbons in the near future, and the Greenhouse gases (GHG) effect of alt- ing the climate worldwide. Mexico, as a developing country, and as the eleventh-most populated nation with the thirteenth-largest territory, and as the owner of important oil production resources, is a good example of a State needing to improve and increase its energy generation. A concerted action amongst the e- nomic sectors involved – both governmental and industrial – could dras- cally improve the present situation regarding the development of its alt- native energy resources. The main motivation for organizing the German-Mexican Symposium 2006 Energy for the future: towards a cleaner planet, was to get a global perspective for changing the present energy-mix in Mexico, currently based on fossil fuels, towards cleaner energy resources.

Tissue-Specific Estrogen Action : Novel Mechanisms, Novel Ligands, Novel Therapies
Nuclear hormone receptors are not only important drug targets, but have also been the focus of decades of active and highly insightful research.The consensus from nuclear receptor research was of course that the signaling pathways mediated by these receptors warrant further research, even though in principle they appeared to represent the most immediate, seemingly simple signaling pathway from hormone (ligand) binding to gene expression changes. In nuclear receptor molecular biology, estrogen receptor research has additional unique facets: since the discovery of ethinyl estradiol

Thymus Gland Pathology : Clinical, Diagnostic, and Therapeutic Features
The thymic pathology is related to several complex congenital, non-oncological, and oncological diseases. Many of these illnesses require a multidisciplinary approach thus involving several specialists: the surgeon, the neurologist, the anesthetist, and the pathologist. For example, myasthenia gravis—the most challenging disease deriving from a thymic trouble—requires an accurate and multimodal treatment. The oncologic pathology of the thymus is likewise complex, and involves also the oncologist and the radiotherapist. In cases of congenital thymic diseases, a transplantation of the thymus can be taken into consideration.
