A pathogenic strain of bacteria, Escherichia coli O157:H7 enterohemorrhagic E. coli or EHEC , has been analyzed by laser-induced breakdown spectroscopy LIBS with nanosecond pulses and compared to three nonpathogenic E. coli strains: a laboratory strain of K-12 AB , a derivative of the same strain termed HF4714, and an environmental strain, E. coli C Nino C . A discriminant function analysis DFA...

En el presente trabajo, se aborda pensamiento de Manuel Atienza a partir sus discrepancias principales, pesar su esencial coincidencia, con postpositivismo discursivo, modelo teórico que comparten autores como Carlos Nino y Robert Alexy. De esta manera, obtienen algunas conclusiones sobre postpositivista del autor español.

Ocean models have been used to study global phenomena such as the El Nino Southern Oscillation. The effects of El Nino are felt worldwide and are of importance to all segments of society. High resolution ocean models are being developed to run more sophisticated simulations. The demand for computing power is expected to increase drastically with the use of high resolution models. Running extend...

Climate variability adversely impacts crop production and imposes a major constraint on farming planning, mostly under rainfed conditions, across the world. Considering the recent advances in climate science, many studies are trying to provide a reliable basis for climate, and subsequently agricultural production, forecasts. The El Niño-Southern Oscillation phenomenon (ENSO) is one of the princ...

It is known that the El Nino Southern Oscillation (ENSO) phenomenon induces marked climate variability across many parts of the world. However, in seeking useful relationships between ENSO and climate, several indices are available. In addition to the choice of index, previous studies assessing ENSO effects have employed a range of different methods to classify periods as El Nino, La Nina or Ne...
