Abstract: Methods for seeding live cells onto spatially defined regions of a substrate including multiple features (e.g., microwells or other microenvironments) utilize a stencil embodied in a hole-defining sacrificial film. A sacrificial film devoid of holes may be applied over features of a substrate, and a hole generating mechanism (e.g., hot needle or laser) aligned with features may be used to define holes in the film. Alternatively, holes may be predefined in a sacrificial film to form a stencil, and the stencil may be assembled to the substrate with the holes registered with features thereof. Thereafter, cells are seeded through holes in the film. Seeded cells are subject to incubation, further processing, and/or performance of one or more assays, and the hole-defining sacrificial film (stencil) may be removed.

Abstract: A portable support including a mounting assembly configured to be releasably located relative to a surface or object, a body associated with a portion of the mounting assembly and extending at an angle therefrom and a substantially U-shaped or V-shaped yoke provided relative to the body.

Abstract: A lock box including a main body, a lid, an electronic locking mechanism, a lid sensor, and a processing circuit. The main body defines a compartment. The main body is structured to be secured within or secured to a substantially permanent structure. The lid is positioned to selectively enclose the compartment. The electronic locking mechanism is positioned to selectively lock the lid to the main body. The lid sensor is configured to detect at least one of an attempt to open the lid or opening of the lid. The processing circuit is configured to generate an alert in response to the lid sensor detecting the at least one of the attempt to open the lid or the opening of the lid.

Abstract: The invention provides for compositions and methods for the preservation of meat tissues, including fish, beef, poultry and pork us phospholipase A2 (PLA2) enzymes.

Abstract: A system includes a remote server and a device having a wireless transceiver, microphone, and processing circuit. The processing circuit is configured to monitor the microphone for a siren signature. The processing circuit is configured to use the wireless transceiver to send information to the remote server in response to a detection of the siren signature. The remote server causes wireless cameras located near the device to capture a current image and to send the captured image to the remote server for further distribution.

Abstract: A soldering attachment apparatus having bendable magnetic arms and a substantially planar metal base. The base is constructed of a ferrous metal and the arms are comprised of flexible steel gooseneck having a bottom portion with a magnet, and a top portion having an alligator clip or other accessory. The arms are magnetically coupled to the base via the magnet. The arms can be of varying length and are easily removed or slid across the metal base for unlimited repositioning. This repositioning allows the user to angle an object for optimum soldering. The soldering tool can be used to hold circuit boards, jewelry, 3D printed parts and a variety of other objects when soldering.

Abstract: Steel railroad rails including carbon, manganese, silicon and greater than 0.45 wt % to 1 wt % copper are provided having greater hardness and yield strength than standard steel rails containing less than 0.45 wt % copper. As an example, the ultimate tensile strength of the steel rails is from 1170 MPa to 1725 MPa. As an additional example, the hardness of the steel rails measured 2 mm from the running surface of the rail is from 35 to 50 on the Rockwell C scale.

Abstract: Exposure to ionizing radiation can produce a well-defined dose dependent signature in terms of changes in gene expression. In approaches and devices described herein, such a signature can be used to generate and use a self-contained radiation biodosimeter device, based on, for example, a blood finger stick. Various aspects of the invention are directed to biodosimetry with a fully integrated biochip using gene expression signatures.
