Gene swapping in the dead zone

Viruses can swap DNA between bacteria that live in regions of the oceans with little or no oxygen.

Bringing new life to the dead zone.

The Gulf of Mexico “dead zone” reached a record 7,700 square miles in the summer of 1999. That year, heavier flow in the Mississippi River brought an abundance of nutrients to the Gulf, resulting in hypoxia, or inadequate dissolved oxygen in bottom waters that forces bottom-dwelling animals to either flee or die. With the year 2001 have come legislative efforts to reduce the dead zone—if not ki...

Dead Zone Compensation in Pneumatic Servo Systems

This paper presents an approach for dead zone compensation in pneumatic position servo systems. The dead zone is an inherent nonlinearity in pneumatic servovalves, where for a range of input control values, the valve gives no output flow. Although pneumatic actuators are very common in industry, they have limitations in servo pneumatic applications that are caused by typical non-linearities of ...

Note on the “Dead Zone” in Layered Accretion Models

Current layered accretion models neglect the properties of the “dead zone”. However, as argued here from simple considerations, the thickness of this zone is a critical quantity when the disc is in hydrostatic equilibrium. It controls not only the structure of the superficial, active layers, but also the mid-plane density and the total disc mass, and should therefore be introduced in models of ...

Gene Transfer: Gene Swapping Craze Reaches Eukaryotes

Recent studies have provided evidence for gene transfers from prokaryotes to eukaryotes and between eukaryotes. The mechanisms and frequencies of these transfers remain the subject of speculation, but the findings provide ample reason to seriously consider interspecies gene transfer as an important evolutionary process in eukaryotes.
