Abstract: A spinning cell device is described for fast and convenient standardization and analysis of constituents and isotopes in solid samples by laser ablation inductively coupled plasma (LA-ICP) spectrometry. The method and apparatus for performing he method require the sample under test and a standard to be spun during ablation allowing the quasi-simultaneous ablation of both materials. The aerosols resulting from the ablation of sample and standard are mixed in the ablation cell allowing quantification of the ablated metals by the method of standard addition or isotope dilution. The relative proportion of standard verses sample ablated can be changed by altering the trajectory of the laser beam. The ablated aerosol is swept into an inductively coupled plasma by a carrier gas and analyzed by mass spectrometry.

Abstract: The embodiments herein relate to a magnetic field feedback based spintronic microwave oscillator driven by DC current. The microwave oscillator works based on a magnetic tunnel junction structure connected to a feedback waveguide. Any fluctuation in the magnetization direction of free magnetization layer of MTJ drives an oscillating current through the feedback waveguide which in turn exerts an oscillating magnetic field on the free layer and amplifies the magnetization fluctuations. If the DC current passing through the MTJ is more than a critical value, continuous processing states of the magnetization are possible. The critical current is independent of the thickness and magnetization of the free layer. A MTJ can be driven into spontaneous oscillations with DC current and magnetic field feedback circuit and can act as a spintronic microwave oscillator.

Moreover, a pharmaceutical composition containing said monomers or dimers and various medical uses are described.

Abstract: A method and system for controlling recirculated exhaust gas composition and quantity provided to an internal combustion engine, which has one or more separately controllable combustion cylinders, a main exhaust line and an exhaust gas recirculation (EGR) loop. A first exhaust valve is connected to the main exhaust line, and a second exhaust valve is connected to the EGR loop. The operation of the exhaust valves is controlled such that exhaust does not flow through both exhaust valves at the same time. Control of the exhaust valves is coordinated with the main fueling event used to control the exhaust composition exiting each valve for every cylinder on every cycle. During each engine cycle, a post-combustion fuel injection event is also used to add fuel to the exhaust in-cylinder, which flows only through the second (EGR) exhaust valve.

Abstract: Disclosed is a method of reducing uncertainty, which exactly finds the hydraulic conductivity and the specific storativity of a rock sample in pressure pulse-decay measurement. Axial and confining pressures are applied to the rock sample, and upstream and downstream reservoirs are connected to the rock sample. Coordinate values representing minimum values of a contour of a graph of an objective function, in which the hydraulic conductivity and the specific storativity obtained through the pressure pulse-decay measurement scheme to apply pressure pulses from the outside are expressed in horizontal and vertical axes are found from the graph. The coordinate values are set as the hydraulic conductivity and the specific storativity of the rock sample. Graphs of objective functions obtained by repeating the pressure pulse-decay measurement while changing boundary conditions are shown in overlapped, thereby reducing the uncertainty of the hydraulic conductivity and the specific storativity of the rock sample.
