Copper-based epoxy and ablative antifouling painted panels were exposed in natural seawater to evaluate environmental loading parameters. In situ loading factors including initial exposure, passive leaching, and surface refreshment were measured utilizing two protocols developed by the US Navy: the dome method and the in-water hull cleaning sampling method. Cleaning techniques investigated incl...

Passive sampling is an approved and accurate method for the assessment of organic compound exposure over long sampling time. This method could be very convenient for the short-time exposure assessment, but passive samplers have to be validated for this use. In this article, the behaviour of two commercial passive samplers (GABIE and Perkin Elmer) under fluctuant concentration conditions is stud...

Introduction: Cigarette smoking affects nitric oxide production. The aim of this study was to determine associations between tobacco smoke and serum nitric oxide metabolites (NOx) concentration. Methods: Serum NOx concentration was measured by the Griess method in 230 nonsmokers, 238 active, 196 passive and 29 waterpipe smokers. Subjects were selected from participants of Tehran Lipid and Gl...

Helicopters generate substantial noise levels, especially at low frequency. These noise levels are normally not harmful for rpm Rotation per minute the ear. However, the low frequency content masks the speech . Therefore, pilots tend to set the communication system at maximum level so that the sound levels reach severe amplitudes for the ear. These high sound levels are exposing the ear to fati...

This paper considers the problem of discrete passive filter design method for singular systems with interval time-varying delay. A bounded real lemma (BRL) for discrete passivity with a dissipation of discretetime delayed singular systems by a Lyapunov function is derived. A delay-dependent discrete passive filter design method is proposed by linear matrix inequality (LMI) approach on the basis...

The ability of 135 Staphylococcus strains isolated from Spanish dry-cured hams to produce enterotoxins in culture was investigated by the reversed passive latex agglutination method. A high percentage of enterotoxigenic Staphylococcus aureus strains (85.9%) was recorded, and 54.3% of these produced enterotoxin A. One of the two Staphylococcus epidermidis strains produced enterotoxin C. The reve...

The OLED self luminous display device features high brightness, high contrast, a wide field of vision with a rapid response and is compact as well as light-weight. At the present time the device is implemented in sub-main displays for mobile phones along with other mobile devices, such as portable audio systems, as well as small to medium size displays for automotive components, including car a...

The paper presents a new method of more precise estimation of the depth map in 3D videos. The novelty of the proposed approach lies in sophisticated combination of partial results obtained by selected existing passive and active 3D scanning methods. The aim of the combination is to overcome drawbacks of individual methods and this way to improve the accessible precision of the final depth map. ...
