Abstract During ignition and flame spreading processes, the difference in initial rupture size for end cover of cartridge may affect final accumulation form propellant particles. A 3D unsteady state gas -solid two-phase flow model was established based on phase-grain phase coupling method to simulate distribution particles chamber under different sizes cover. The simulation results showed that ...

Internal standardization was applied to the solid-phase extraction of trace elements using following commercially available aminocarboxylic acid-type chelating resins: InertSep ME-2, NOBIAS Chelate PA-1, and Presep PolyChelate. The concentration in initial sample solution can be calculated by ratio added amount internal standard element, Y, that final after extraction, which is proportional vol...

In order to optimize the solid phase extraction (SPE) conditions of perfluorooctanoic acid (PFOA) in raw leachate and treated leachate, effects activator properties, SPE cartridge, pH value, ionic strength, eluent properties were studied through single factor experiments. The optimal results each obtained. Considering that concentration PFOA is lower than have been further optimized. Based on a...

This study conducted scientific analysis and preservation treatment for the local 7 relics (depurator bottle, eagle patten button, rank insignia, mess tin, M1 Grand-gun cleaning tool kit, Carbine bullet, cartridge) of fallen Korean War excavated through MND Agency KIA Recovery & Identification that are possessed in exhibition hall Ground Operations Command. FT-IR results show remainder depu...

Self-containing, ready-to-use cartridges are essential for mobile Lab-on-a-Chip (LoaC) systems intended for Point-of-Care (POC) use. Up to now, a common weak point in many LoaC developments is the need to dispense liquid reagents into the test cartridge before or during processing of the assay. To address this issue we have developed an efficient method for fusing liquid reagents into glass amp...

BACKGROUND This study aimed to observe the effect of hemoperfusion (HP) cartridge on different internal environment indicators at different time points in patients with acute blood poisoning and to find alternative indicators for the detection of blood poisoning. METHODS The levels of internal environment indicators (blood pH, PvCO2, PvO2, blood lactate, potassium, free calcium, bicarbonate, ...

Coring is reported to occur because rubber pieces are shaved off from a rubber stopper when a needle is inserted into the rubber stopper of transfusion liquid formulation. We verified whether coring really occurs in insulin vials of self-injecting patients. We collected insulin cartridges from 30 hospitalized patients and used the primary injection (trial injection), the secondary injection and...
