Single-Shunt Measurement of Three-Phase Currents for a Three-Level Inverter under the Low Modulation Index Operation.

This paper deals with the three-phase current reconstruction method under the low modulation index operation of three-phase three-level PWM inverters by using the single-shunt current signal measurement. The shunt is placed in a DC-link. The proposed reconstruction method is based on the combination of collinear vector injection and shifting of Space Vector Modulation (SVM) signals.

A unique case of a 70-hour decompression sickness latency.

We report a unique and well-documented case of a type II decompression sickness (DCS) with a latency interval of 70 hours. It may raise divers' awareness and help medical practitioners to keep suspect divers under close observation longer than before and identify and treat DCS accordingly.

Change of occurance of type 1 and type 2 decompression sickness of divers treated at the Croatian Naval Medical Institute in the period from 1967 to 2000.

A significant change of occurrence (p=0.0343) of type 1 and type 2 decompression sickness (DCS) of divers in Croatia was observed in the period from 1991 to 2002 (type 1: n=26, 37.68% and type 2: n=43, 62.

[Gas gangrene and hyperbaric oxygenation--a lesson forgotten or never learned?].

Gas gangrene develops in devitalized hypoxic tissue. It spreads rapidly under strong influence of enzymes produced by the causing bacteria and often results in fatal outcome. It is of utmost importance to stop toxin production as soon as possible, which is most effectively achieved by early application of hyperbaric oxygenation (HBO2), as the first measure in a "trident" (HBO2, antibiotics, surgical measures).

Recompression therapy of mountain sickness.

This paper describes the treatment of a severe case of acute mountain sickness with a portable hyperbaric chamber. A 37-year old climber was treated for acute high altitude pulmonary oedema, which developed on the North Col of Mount Everest, at an altitude of 7,060 m. The treatment in the portable Gamow bag hyperbaric chamber lasted two hours, with a bag pressure of 103 mm Hg (0.
