BACKGROUND Bacterial meningitis remains often etiologically unconfirmed, especially in resource-poor settings. We tested the potential of real-time polymerase chain reaction to identify Streptococcus pneumoniae (Pnc) and Haemophilus influenzae type b (Hib) from cerebrospinal fluid impregnated on filter paper strips. METHODS Pnc and Hib genome equivalents were blindly quantified by polymerase ...

In this paper, a real-time denoising filter based on modelling of stable hybrid models is presented. Thehybrid models are composed of the shearlet filter and the adaptive Wiener filter in different forms.The optimization of various models is accomplished by the genetic algorithm. Next, regarding thesignificant relationship between Optimal models and input images, changing the structure of Optim...

in this research, active capacitance circuit and the feature of negative resistance are analysed in details. also, a new active filter is presented based on active capacitance circuit. for simulations, we used matlab and advanced design system(ads). proposed active filter (rf) is a narrow band filter. the results of simulation shows some aspects of sustainability and low noise feature. the circ...

Filter is one of the main components of embankment dams. By a simple but effective performance, filter protects the dam against erosion and soil scouring in impervious core caused by leakage (piping) and makes it safe. Interaction between filter and erodible base soil is a complex phenomenon which is dependent upon several factors, and has challenged researchers for better understanding the fil...

Separation of solids from fluid is a vital process to achieve the desired level of purification in industry. Contaminant filtration is a common process in a variety of applications in industry. Clogging of filter phenomena is the primary failure mode leading to replacement or cleansing of filter. Reduced performance and efficiency or cascading failures are the unfortunate outcomes of a clogged ...

SUMMARY We consider a Leray model with a deconvolution-based indicator function for the simulation of incompressible fluid flow at moderately large Reynolds number (in the range of few thousand) with under-resolved meshes. For the implementation of the model, we adopt a three-step algorithm called evolve-filter-relax (EFR) that requires (i) the solution of a Navier-Stokes problem, (ii) the solu...

Flameless venting is a sort of dual mitigation technique allowing, in principle, to vent process vessel inside building where people are working without transmitting flame outside the protected vessel. Existing devices an assembly panel and metal filter so that exploding cloud front forced go through filter. Within frame ATEX Directive, those systems need be certified. To do standard (NF EN 160...

Inferior vena cava (IVC) filters have become essential components in deep vein thrombosis treatment, and are particularly critical for preventing pulmonary embolisms in anticoagulation-resistant patients. Filter efficacy relies on maintaining IVC patency, or openness, by preventing filter-induced thrombosis following clot capture. A computational fluid dynamics (CFD) model has been developed to...
