investigation on structure and dynamics of natural forest ecosystems is an important issue for silvicultural decisions. the aim of this study is to analysis dynamics and structure of a beech stand during 5-year period in the shast kalateh forest in the caspian region, north of iran. data were collected from a 16.9ha permanent research plot established in a natural unlogged stand in 2006. all li...

In studying the case studies of traditional architectures according to Christopher Alexander’s theory about “the nature of order” and the fifteen fundamental properties introduced, it is important to note that the ontology of the theory is based on human’s indigenous feeling about architecture, which subsequently implies these kind of studies to be based on people’s cognitive images induced fro...

styrene nanocomposites were synthesized by in-situ atom transfer radical polymerization at 110oc. the variations of monomer conversion and the linearity of semilogarithmic kinetic plot, some signs of living polymerizationand constant radical concentration in the reaction medium, were revealed by gas chromatography technique (gc). according to the gel permeation chromatography (gpc) results, the...

Intrinsically disordered proteins such as FlgM play important roles in biology, but little is known about their structure in cells. We use NMR to show that FlgM gains structure inside living Escherichia coli cells and under physiologically relevant conditions in vitro, i.e., in solutions containing high concentrations (>/=400 g/liter) of glucose, BSA, or ovalbumin. Structure formation represent...

Sociology points to the many rules that guide behaviour in everyday situations. The more we learn about the rules of social interaction, the better we can play the game. CHAPTER Such everyday experiences are the focus of this chapter. The central concept is social interaction, the process by which people act and react in relation to others. We begin by presenting several important sociological ...
