AIMS To determine whether quantitative blood culture methods could improve the diagnosis of septicaemic melioidosis. METHODS A comparison of conventional broth based blood cultures, a pour plate method, and a commercial lysis centrifugation (Isolator 10) blood culture system was conducted in 71 Thai patients with severe melioidosis. The time to identification of B pseudomallei was recorded fo...

In this paper, we focus on concurrent programs that use locks to achieve isolation of data accessed by critical sections of code. We present ISOLATOR, an algorithm that guarantees isolation for well-behaved threads of a program that obey a locking discipline even in the presence of ill-behaved threads that disobey the locking discipline. ISOLATOR uses code instrumentation, data replication, and...

The Isolator 1.5 Microbial tube (E. I. du Pont de Nemours & Co., Inc., Wilmington, Del.) is a commercially available blood culture system for use in pediatrics. The methodology is based on blood lysis followed by direct plating of the sample on culture media to detect bacteria and fungi. Comparative recovery rates of pathogens from blood collected in this and a conventional broth system were si...

background : the application of ventilation systems in industries and workplaces is with the aim of improving environmental conditions for employees. the lack of appropriate ventilation system components design and control methods result in the production of sound and vibration in most components. the purpose of this study was to determine the role of the pad isolator in controlling vibration a...

In this paper, we present an Yb-doped Y2O3 waveguide laser fabricated by pulsed laser deposition (PLD) that is Q-switched using a mono-layer graphene saturable absorber. 140 ns pulses at a repetition rate of 1.21 MHz and pulse energy of 14 nJ are achieved at an absorbed pump power of 528 mW. Introduction: Pulsed lasers have a range of applications in areas such as medicine, material processing,...

The 10-ml Isolator system (E.I. du Pont de Nemours & Co., Inc., Wilmington, Del.) was compared with the BACTEC 16A-17A nonradiometric resin system (Johnston Laboratories, Inc., Towson, Md.) for isolation of organisms from 6,839 paired blood cultures. Equal volumes of blood (6 to 10 ml for each Isolator and 3 to 5 ml for each BACTEC bottle) were cultured in parallel in the two systems, and 600 i...

Synovial fluid specimens obtained from patients with arthritis were plated onto solid media (conventional cultures) or inoculated into an Isolator 1.5 microbial tube (Isolator cultures), and the yield and time to detection of organisms were compared. Overall, 144 specimens obtained from 137 patients were processed, and 31 (21.5%) cultures obtained from 29 patients were positive by at least one ...

Optical isolators are indispensible components in nearly all photonic systems as they help ensure unidirectionality and provide crucial protection from undesirable reflections. While commercial exclusively built on magneto-optic (MO) principles not readily implemented within integrated circuits due to the need for specialized materials. Importantly, MO effect is generally weak, especially at sh...

We studied the recovery of 1,270 fungal isolates from 176,144 Isolator blood cultures (0.72% positive) on bacterial and fungal media, under routine and differing incubation conditions. Except with Histoplasma capsulatum, chocolate agar incubated for only 3 days proved to be an excellent medium for the recovery of fungi from the Isolator system.
