To the Editor: Cubicin (daptomycin for injection; Cubist Pharmaceuticals, Lexington, MA) is a cyclic lipopeptide antibacterial indicated in the United States for the treatment of complicated skin and skin structure infections and Staphylococcus aureus bloodstream infections, including those with right-sided infective endocarditis.1 Daptomycin’s prescribing information states that parenteral dru...

Due to recent repeatability problems with the gravimetric analysis procedure used for military conformance testing of military specification hydraulic fluids, an in-depth investigation was undertaken to evaluate possible sources of error. Many sources of weight change exist, including particulate and water accumulation from air, buildup of static electricity causing interference with the metal ...

(1) High-efficiency particulate air (HEPA) filtration: the HEPA-filtration system used a prefilter screen, a bag filter (Eurovent [EU] 8 rating), and a HEPA filter (EU13 rating). (2) 2×-low-cost filtration: The low-cost-filtration system contained mosquito netting (prefilter), 2 fiberglass furnace filters, and 2 electrostatic furnace filters. (3) Bag filtration: Bag filtration involved the use ...

− The particulate contamination of intravenously administered fluid has been of major concern. One of the most common complications associated with long term i.v. therapy is post-infusion phlebitis (PIP). We undertook a systematic review and meta-analysis of the effect of inline filters on PIP. An electronic search of Medline, KoreaMed, and KRIST was conducted to identify randomized controlled ...

Over the Jast several years, the Waste Treatment and Immobili zation Plant (WTP) contractor has executed a test program and analysis effort to establish an aerosol entrainment coefficient (AEC) value for confinement ventilation system designs. The Board advises that the recommended AEC values from this program may not bound expected conditions at the WTP. The AEC values are key design parameter...

A field study was performed to develop emission rates for dust exposure at a food processing facility. Eight 2-hour periods were monitored over 2 days. Area total suspended particulate samples were collected on 37 mm polyvinyl chloride filters with 5 mum pore size according to NIOSH Method 0500. Filters were analyzed gravimetrically. Ventilation and production activity data were collected durin...

This paper presents the simulation, design and implementation of bandpass filters in rectangular waveguides. The filters are simulated and designed by using a numerical analysis program based on the Wave Iterative Method (WIM) called WFD (Waveguide Filter Design) simulation. This simulation program can analyze the electrical network of filters. The sample waveguide filter is designed based on a...

UNLABELLED A study was carried out to investigate the feasibility of achieving ultra low respirable suspended particulates (RSP) in commercial offices without major modification of existing ventilation systems by enhancing the particulates removal efficiency of existing central ventilation systems. Four types of filters which include pre-filters, cartridge filters, bag filters and high efficien...

This paper is a comprehensive study dealing with the parameters that influence the response of a resistive soot sensor which was developed for Diesel Particulate Filter (DPF) failure detection in a past project. From the conductance measurement between two Pt electrodes, and a regeneration strategy, this kind of sensor can provide the weight concentration of particulate matter (PM). In this stu...
