  • There can be little doubt that organized disaster behaviors are an inherent trait among people throughout the world and throughout history. In the past, organized disaster behaviors were primarily in reaction to life-threatening events arising in the natural environment. These reactions reflected our adaptive ability in an often chaotic natural world to initiate organized social survival skills. They have stood us in good stead for millennia. Today, we face disasters of our own making.

  • Accurate statistics on cancer occurrence and outcome are essential both for the purposes of research and for planning and evaluation programmes for cancer control (Parkin, 2006). Although tumours of thyroid account for only 1% of the overall human cancer burden, they represent the most common malignancies of the endocrine system and pose a significant challenge to pathologists, surgeons and endocrinologists. Among epithelial tumors, carcinomas of follicular cell origin far outnumber those of C-cell origin.

  • Plants are a distinct kingdom of organisms that possess unique properties of reproduction, development, physiology, and adaptation. Plant diversity refers to the variety of plants that exist on the Earth. Plants, in order to survive, have to compete with other plants and organisms in an ecosystem. Over time, they have developed various characteristics to help them survive, which leads to plant diversity.

  • With regard to the interest rate environment, we expect that the ECB will continue to raise key rates in the near future. There are several reasons why the ECB will tighten policy somewhat. One is that inflation has remained above the target for a long time, albeit moderately, and in the recent survey reported by the ECB inflation forecasts were raised slightly compared to the previous one. Also, the monetary overhang, which the ECB interprets as one leading indicator for future inflation, increased further due to persistently high money growth.

  • To be effective in a national setting, international standards require the force of law or other regulatory backing. If not, compliance becomes a matter of non-transparent discretion on the part of preparers and auditors of financial statements, outside the constraints of any regulatory framework. In such cases, the standards should more properly be considered “offshore” rather than “international.

  • The term engineering itself has a much more recent etymology, deriving from the word engineer, which itself dates back to 1325, when an engine'er (literally, one who operates an engine) originally referred to "a constructor of military engines."[4] In this context, now obsolete, an "engine" referred to a military machine, i.e., a mechanical contraption used in war (for example, a catapult). Notable exceptions of the obsolete usage which have survived to the present day are military engineering corps, e.g., the U.S. Army Corps of Engineers....

  • The chapters in this book review the latest advances in the molecular mechanisms of autophagy, highlighting some of the most challenging research topics. The focus is mainly on how this basic cell defense mechanism comes into play in various pathologies, including liver diseases, myopathies, infectious diseases, cancers and neurodegenerative diseases. In these diseases, the contradictory autophagy roles of cell survival versus cell death emphasize the necessity of taking into account this double-edged nature in future development of already promising, autophagy- modulating, therapies....

  • "Seeing" machines and "intelligent" robots have been the focus of research conducted by the Institute of Measurement Science since 1977. Our goal is to gain a basic understanding of vision, autonomy and intelligence of technical systems, and to construct seeing intelligent robots. These should be able to operate robustly and at an acceptable speed in the real world, to survive in a dynamically changing natural environment, and to perform autonomously a wide variety of tasks. In this paper we report...

  • Autophagy is an evolutionarily conserved lysosomal pathway used to degrade and recycle long-lived proteins and cytoplasmic organelles. This homeostatic ability makes autophagy an important pro-survival mechanism in response to several stresses, such as nutrient starvation, hypoxia, dam-aged mitochondria, protein aggregation and pathogens.
