The Obscure Features Hypothesis (OFH) for innovation states that a two-step process undergirds almost all innovative solutions: (1) notice an infrequently observed or new (i.e., obscure) feature of the problem and (2) construct an interaction Litter Accessories involving the obscure feature that produces the desired effects to solve the problem.The
The resonance power buoy is a convincing tool that can increase the extraction efficiency of wave energy.The HID Accessory buoy needs a corresponding draft, to move in resonance with waves within the peak frequency band where wave energy is concentrated.However, it must still be clarified if the buoy acts as an effective displacement amplifier, whe
Arsenic is a ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [As(III)] and arsenate [As(V)].Arsenic resistance in Synechocystis sp.strain PCC 6803 is mediated by the arsBHC operon and two additional arsenate reductases encoded by the arsI1 and arsI2 genes.Here we describe the genome-wide respons
Throughout history, cities have experienced more or less lasting crises that have led to significant declines in population and economic activity and even to their destruction.However, contemporary dynamics have led to strong disparities on a global, national and metropolitan scale and concentrate the decrease in certain areas and cities.In a conte
