STUDY OBJECTIVES To evaluate features of the peak expiratory flow (PEF) test protocol, and to characterize patterns of reproducibility in multiple PEF measurements. DESIGN Cross-sectional study. SETTING University population. PARTICIPANTS Two hundred twenty-three healthy adults. INTERVENTIONS Participants recorded five PEF measurements in each of five sessions per day for 1 week. MEAS...

Despite a large amount of effort devoted in the past years trying to limit unsolicited mail, spam is still a major global concern. Content-analysis techniques and blacklists, the most popular methods used to identify and block spam, are beginning to lose their edge in the battle. We argue here that one not only needs to look into the network-related characteristics of spam traffic, as has been ...

Simulation models are mathematical/logical representations of real-world systems. Microscopic traffic simulation models have been playing an important role in traffic engineering and particularly in cases, in which field studies, involving extensive data collection, over a wide range, is difficult or expensive to conduct. As the available simulation models can only replicate homogeneous traffic...

this study was aimed at evaluating the flow behavior characteristics of yogurt enriched with fish oil (fo) microcapsules prepared by complex coacervation method. fo was microencapsulated in gelatin-acacia gum coacervates. then, the microcapsules were dried, and yogurt was produced from the milk enriched with microcapsules powder. rheological characteristics (as measured using a rotational visco...

We experimentally studied the air–water pressure drop characteristics with inner diameters of 20 mm under stable and transverse vibration conditions in horizontal circular channel. experimented status gas-phase conversion flow velocity Jg at 0.1–20 m/s, liquid-phase Jw 0.1–3.0 m/s. In this paper, we discuss effect velocity, amplitude, frequency on drops. With increasing performance drops become...

This paper reports a numerical study on the force convection heat transfer and flow characteristics of a nanofluid containing water and Tio2 with various volume fractions (0.002
