This invention is related to a flow fluorometric device and method employing a two-photon excitation and / or confocal optical set-up. The optical set-up of this invention is optimal for counting small fluorescent biological particles. The active focal volume is diffraction-limited and consequently much smaller than the volume of the flow channel. The excitation and detection concept has been found very efficient for rejection of the background signal. An objective lens with large numerical aperture for focusing the laser and for collecting the fluorescence is used and this restricts the active volume of measurement to a diffraction-limited volume which approximately corresponds to a volume of femtoliter. This volume is significantly smaller than the detection volume of ordinary flow cytometry.

A data backup system for use with a server running a storage application that writes and reads data blocks. The system includes a self archiving log structured volume for copying blocks from an active volume while the application is running without contending with the application for access to data blocks. The volume records the result of every write event in a new location in primary storage, forming a chronological log of the state changes the volume undergoes. The volume records in the log the points in time (synch events) when the blocks of the volume are in a consistent state with respect to the application. The system further includes backing storage to store the archived blocks and synch events of the volume. The volume migrates inactive segments of its log to the backing storage and ensures that a volume can be reconstructed from a fixed number of log segments.

The device comprises a distillation unit arranged between two furnaces (59′, 79′) in a temperature-controlled container (48′). Said distillation unit comprises 100 flat thin hollow plates having a surface of 20 dm2 by face and an active volume of 200 dm3.

Systems and methods for storing energy in gaseous form in submerged thin-walled tanks are secured to the ocean or lake floor but are open to the water at the tank bottoms and are configured to be filled with gas while submerged.A conduit operatively connected to the tanks provides flow from a surface source of an energy-containing gas to the tank interiors. Surface or subsurface pumping apparatus which may include piston-less pressure cylinders or have leveraged pistons provide a preselected flow rate of the energy-containing gas into the containment structure interior against a back pressure essentially equal to the static pressure of the body of water at the location of the tank to displace an equivalent volume of water through the open bottom. The conduit can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank using Aluminum activated with Galinstan.

We introduce a new technology for Manufactureable, High Power Density, High Volume Utilization Nuclear Batteries. Betavoltaic batteries are an excellent choice for battery applications which require long life, high power density, or the ability to operate in harsh environments. In order to optimize the performance of betavoltaic batteries for these applications or any other application, it is desirable to maximize the efficiency of beta particle energy conversion into power, while at the same time increasing the power density of an overall device. The small (submicron) thickness of the active volume of both the isotope layer and the semiconductor device is due to the short absorption length of beta electrons. The absorption length determines the self absorption of the beta particles in the radioisotope layer as well as the range, or travel distance, of the betas in the semiconductor converter which is typically a semiconductor device comprising at least one PN junction. Various devices and methods to solve the current industry problems and limitations are presented here.
