Abstract: The present invention concerns the use of a magnesium-including compound as binder for producing metallic ore fluxed pellets, in particular iron ore fluxed pellets, said magnesium-including compound comprising semi-hydrated dolime fitting the general formula aCa(OH)2·bMg(OH)2·cMgO, a, b, and c being weight fractions wherein the weight fraction b of Mg(OH)2 is between 0.5 and 19.5 % by weight with respect to the total weight of said semi-hydrated dolime.

Abstract: A needle-free injector monitors the compression of a gas bubble within a cartridge of injectate during operating of a plunger in a pre-injection phase. When the gas bubble becomes sufficiently compressed (e.g., at or near the equilibrium pressure during the piercing phase), the velocity of the plunger of the needle-free injector is changed to the piercing rate for delivery of the injectate to a target. By detecting the gas bubble compression prior to delivery of injectate in this manner, an injection stream can be controlled to more closely reproduce a target injection profile. For example, the integrator error for an injector control model can be mitigated, stream acceleration can be optimized/maximized, and overshoot in the injector response (e.g., stream velocity or plunger movement) can be minimized.

Abstract: Respiratory rate can be calculated from an acoustic input signal using time domain and frequency domain techniques. Confidence in the calculated respiratory rate can also be calculated using time domain and frequency domain techniques. Overall respiratory rate and confidence values can be obtained from the time and frequency domain calculations. The overall respiratory rate and confidence values can be output for presentation to a clinician.

Abstract: A mineral composition is shown which contains a mixed solid phase of synthetic calcium and magnesium carbonates, formed of a crystallized calcic portion and a plate-like crystallized magnesian portion. The crystals of the calcic portion and those of the magnesian portion are aggregated in the form of composite aggregates. These aggregates themselves are at least partly agglomerated in the form of agglomerates. The calcic portion has at least one carbonate such as calcite or the mixtures of calcite and aragonite. The magnesian portion contains hydromagnesite in plate-like form. The aggregates are further formed of a calcic core on which hydromagnesite plates are aggregated. The mineral composition has defined thermal conductivity properties making it suitable for use as a building material.
