Trapped charge dating is a commonly used chronological tool in Earth Sciences and Archaeology. The two principle methods are luminescence dating and electron spin resonance. Both are based on stored energy produced by the absorption of natural radioactivity in common minerals such as quartz and feldspars, and in some biological materials such as tooth enamel. Methodological developments in the last 20 years have substantially increased the accuracy and precision of these methods. This compilation offers a taste of the recent research into both method and applications.
In spite of intensive investments and investigations carried out in the last decade, many aspects of the stem cell physiology, technology and regulation remain to be fully defined. After the enthusiasm that characterized the first decade of the discovery that when given the right cue, stem cells could repair all the different tissues in the body; it is now time to start a serious and coordinated action to define how to govern the stem cell potential and to exploit it for clinical applications. This can be achieved only with shared research programs involving investigators from all over the world and making the results available to all.The Disputationes Workshop series (http://disputationes.i...
This book contains peer-reviewed papers from the Second World Landslide Forum, organised by the International Consortium on Landslides (ICL), that took place in September 2011. The entire material from the conference has been split into seven volumes, this one is the first: 1. Landslide Inventory and Susceptibility and Hazard Zoning, 2. Early Warning, Instrumentation and Monitoring, 3. Spatial Analysis and Modelling, 4. Global Environmental Change, 5. Complex Environment, 6. Risk Assessment, Management and Mitigation, 7. Social and Economic Impact and Policies.

New and innovative scientific theories, discussion and explanations are presented on landform dynamics and evolution in Romania along with a comprehensive understanding of the geomorphological processes shaping the large variety of Romania’s landscape. Thematically arranged the book deals with landform dynamics of specific relief types: glacial and periglacial, denudational, fluvio-denudational, fluvial, karst and coasts, as well as sediment fluxes, geomorphic hazards and risks. The authors are key scientists and researchers in the field and offer innovative views on research methods and concepts applied to the topics in question. This work will be of interest to students and researchers in geography, geomorphology, geology, environmental science, paleoclimatology and soil science as well as policy and decision-makers in spatial planning.

Sunt convinsă că, în gând sau vădit, românii, oriunde s-ar afla, recunosc matricea, cele şase acorduri pe care se împletesc capodopere. Și fie tâmplar care înfrumusețează case, fie instalator care face artificii tehnice, fie zidar care își lasă sudoarea pentru trăinicia construcției, fie orice, bucătar, ospătar, îngrijitor, ale căror nume se pierd, toți știu că muntele munte se zice, iarba iarbă se spune, izvorul izvorăște, viața se trăiește. Românii rămași în țară întind mâini sigure și solide celorlalți români care, pe cărări neumblate, poartă în suflete roșul din nesfârșitele livezi, galbenul încărcat al holdelor de grâu și albastrul neîntinat al cerului.
