Novel Species of Non-Spore-Forming Bacteria

One new bacterial species was discovered in a regenerative enclosed life-support module air system. While cataloging cultivatable microbes from the airborne biological diversity of the atmosphere of the Regenerative Enclosed life-support Module Simulator (REMS) system at Marshall Space Flight Center, two strains that belong to one novel bacterial species were isolated. Based on 16S rRNA gene sequencing and the unique morphology and the taxonomic characteristics of these strains, it is shown that they belong to the family Intrasporangiaceae, related to the genus Tetrasphaera, with phylogenetic distances from any validly described species of the genus Tetrasphaera ranging from 96.71 to 97.76 percent.

Chamber for Aerosol Deposition of Bioparticles

Standard coupons can be covered with reproducible areal concentrations of bioparticles. The laboratory apparatus shown in the figure is a chamber for aerosol deposition of bioparticles on surfaces of test coupons. It is designed for primary use in inoculating both flat and three-dimensional objects with approximately reproducible, uniform dispersions of bacterial spores of the genus Bacillus so that the objects could be used as standards for removal of the spores by quantitative surface sampling and/or cleaning processes. The apparatus is also designed for deposition of particles other than bacterial spores, including fungal spores, viruses, bacteriophages, and standard micron-sized beads. The novelty of the apparatus lies in the combination of a controllable nebulization system with a settling chamber large enough to contain a significant number of test coupons. Several companies market other nebulizer systems, but none are known to include chambers for deposition of bioparticles to mimic the natural fallout of bioparticles.

Vision, Software Enhancements Advance Robots

Robotics technology has made measurable strides in the last few years. Today’s robots can move with greater precision over a more flexible range of motion, while handling heavier payloads. Advances in vision systems and software are giving robots the ability to recognize and handle a wider range of parts than before, and make decisions that only humans could previously perform.

Understanding Robot Movements Through Kinematics

Many robotic and mechanical systems require the calculation of kinematic equations to express the relationship between variables that are to be controlled (motor/actuator position obtained via feedback sensors and manipulated by motors/actuators) and variables that are to be commanded, such as the position of a tool tip or objective.

Matrox Helps Military Vehicles Get the Robotic Touch

To camouflage an object is to hide it, conceal it so that it blends in with the surrounding environment. For the military, it’s a tactical necessity and can make the difference between a platoon’s success or failure, a soldier’s life or death. It’s no wonder that the military takes camouflage very seriously. Especially for vehicles.
