Mapping of potentially hazardous elements in the Cambrian Vendian aquifer system, northern Estonia

A Paleogeographic Model for Vendian and Cambrian Time

δ13C Stratigraphy of the Birmania Basin, Rajasthan, India: Implications for the Vendian- Cambrian Transition

Overview The paleogeographic reconstruction of the late Neoproterozoic assumes a marked significance due to the fact that the interactions between the biosphere, atmosphere, hydrosphere, and geosphere during this time strongly influenced the evolution of life and initiated a remarkable phase of organic evolution, well documented in the rocks of this age. Time-related changes in these carbon res...

the effect of the record infancy in crimilly acts of guilties (in karaj city)

چکیده یکی از مهمترین دغدغه های بزرگ جوامع بشری، از دیر باز تا کنون که ذهن پژوهشگران و متخصصان بهداشت روانی و اجتماعی و دولتها رابه خود مشغول داشته، مسأله ی بزهکاری می باشد. شناخت کامل پدیده ی بزهکاری و بزهکار، علل وعوامل سقوط یک انسان، چگونگی درمان وی و درنهایت پیشگیری ازبزهکاری ودریک کلام سالم سازی یک جامعه، رسالت عظیم، انسانی ومقدسی می باشد که با بررسی شخصیت مجرم یعنی[ انسانی که تحت شرای...

Phytoextraction of potentially toxic elements by six tree species growing on hazardous mining sludge

The aim of the study was to compare the phytoextraction abilities of six tree species (Acer platanoides L., Acer pseudoplatanus L., Betula pendula Roth, Quercus robur L., Tilia cordata Miller, Ulmus laevis Pall.), cultivated on mining sludge contaminated with arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), thallium (Tl), and zinc (Zn). All six tree species were able to survive on such an un...

Automated Integration Of Potentially Hazardous Open Systems

I speculate on the feasibility of open systems that self-assemble into integrated systems of systems using automation to identify and manage novel hazards. 1. Automated Integration of Open Systems One of the benefits expected of open systems is that they can be combined as systems of systems to deliver some integrated service beyond that provided by any of the constituents alone. Of course, we ...
