Creation or evolution

The difficulty in predicting locally and globally the transient evolution of two-phase or multiphase flows in complex systems is well recognized in nuclear thermal-hydraulics. Large efforts involving the expenditure of huge resources during the last three decades in previous century brought to the creation of giant databases (e.g. including experimental data and results of computer code calculations) and to the perception that the safety of nuclear reactors is guaranteed notwithstanding residual areas of unawareness.

The C4 photosynthetic carbon cycle can be explained as the elaborated addition to the C3 photosynthetic pathway. It is a unique series of biochemical, anatomical and regulatory gene characteristics that concentrate CO2around the carboxylating enzyme Rubisco, thereby increasing photosynthetic efficiency during high rates of photorespiration. The C4 photosynthetic pathway has evolved as an adaptation to high light intensities, high temperatures and dryness, therefore in the warmer climates of the tropical and subtropical dominating the grassland floras and biomass production.

The conceptual evolution of Knowledge Management (KM) has been supported by the use of flexible processes and several computational tools. The sophistication of these tools, incorporating the KM concepts, has been growing with time, creating functions better suited to knowledge creation processes. However, centralized Knowledge Management Systems (KMS) present some inconveniences, such as inflexible knowledge codification structures and centralised control.

Scientific and technological advances have had profound effects on human life. In the 19th century, most families could expect to lose one or more children to disease. Today, in the United States and other developed countries, the death of a child from disease is uncommon. Every day we rely on technologies made possible through the application of scientific knowledge and processes.
