Abstract: A convenient, water-saving and labor-saving FROG irrigation controller and system are provided, which determine the appropriate water budget and schedule for the property's landscaping based on evapotranspiration data for the geographic area, any regulation data, and property-specific data, with consideration given to reduction in watering days, increase in soil watering depth, and day of year. Once set, the FROG controller provides incremental adjustments over the course of the year; the homeowner no longer needs to re-set the watering program seasonally to automatically comply with local mandated and voluntary watering restrictions. One aspect provides a web-based wizard that is used to determine a customized water budget/schedule which is input into the FROG controller. Another aspect provides an integration of a network of FROG controllers with a central command unit.

Abstract: The invention discloses the use of single-stranded RNA toeholds of different lengths to promote the re-association of various RNA-DNA hybrids, which results in activation of multiple split functionalities inside human cells. Previously designed RNA/DNA nanoparticles employed single-stranded DNA toeholds to initiate re-association. The use of RNA toeholds is advantageous because of the simpler design rules, the shorter toeholds, and the smaller size of the resulting nanoparticles compared to the same hybrid nanoparticles with single-stranded DNA toeholds. Moreover, the co-transcriptional assemblies result in higher yields for hybrid nanoparticles with ssRNA toeholds.

Abstract: A pipe shaker apparatus is configured to shake within a pipe and cause the pipe to vibrate. The pipe shaker apparatus includes a rotor having an offset mass. The offset mass is offset from a longitudinal axis through a first end piece of the rotor at a first end of the rotor and a second end piece of the rotor at a second end of the rotor. The pipe shaker apparatus also includes a tubular body having first and second ends. First and second end caps are arranged at first and second ends of the tubular body such that air is able to pass through the first end cap, enter the tubular body, cause the rotor to rotate, and exit the tubular body through the second end cap. The rotor is arranged such that rotation of the rotor by the air cases the offset mass to shake the pipe shaker apparatus.
