UNLABELLED Serious adverse outcomes from perioperative hypothermia are well documented. Consequently, intraoperative warming has become routine. We thus evaluated the efficacy of a novel, nondisposable carbon-fiber resistive-heating system. Twenty-four patients undergoing open abdominal surgery lasting approximately 4 h were randomly assigned to warming with 1) a full-length circulating water m...

During expiration, the carbon dioxide (CO2) levels inside the dead space of a filtering facepiece respirator (FFR) increase significantly above the ambient concentration. To reduce the CO2 concentration inside the dead space, we attach an active lightweight venting system (AVS) comprising a one-way valve, a blower and a battery in a housing to a FFR. The achieved reduction is quantified with a ...

Kajian ini bermaksud untuk mengetahui laju transfer kalor yang diserap oleh high temperature superheater (HTS) dan low (LTS) pada unit boiler sebelum sesudah dilakukan soot blower. menggunakan 3 metode yakni, studi literatur, observasi lapangan, wawancara. Hasil analisa menunjukan bahwa Laju (Q_HTS) meningkat setelah 1 jam blower yakni 72240 MJ/jam dari hanya 65434 MJ/jam, 2 72575 66886 73903 6...

The Pulse Width Modulation (PWM) power electronics systems often produce objectionable acoustic noise at the PWM switching frequency. For example, in a fan / blower drive, the drive used for the blower should use “spread spectrum PWM” technology (also known as Random PWM) where acoustic noise radiating through the duckwork is a very seriously concerned. This paper shows the theoretical basis fo...

We conducted a serosurvey of landscapers to determine if they were at increased risk for exposure to Francisella tularensis and to determine risk factors for infection. In Martha's Vineyard, Massachusetts, landscapers (n=132) were tested for anti-F. tularensis antibody and completed a questionnaire. For comparison, serum samples from three groups of nonlandscaper Martha's Vineyard residents (n=...

This study is about the development of a control system design using Programmable Logic Controller (PLC) system which gives food to the fish with a blower method. To perform fish feeding system automatically the control system will include PLC system, touch screen, emergency button, terminal block, speed controller, relay NY-2N, and power supply 240V. The component of the input systems are auto...
