According to the International Dairy Federation, the quality of raw milks shall be evaluated by the determination of "total" bacterial counts, or standard plate count (SPC); after serial dilution of the milk samples, the SPC is determined on Plate Count Agar (PCA) by the "pour plate" method; the viable bacteria are enumerated after aerobic incubation for 2 or 3 days, at 32 °C or 30°C respectively.

Although pyelonephritis is a common disease, it escapes clinical detection in an undesirably high proportion of patients. The present unsatisfactory diagnostic position would be much improved by widespread screening of patients by simple yet reasonably accurate methods. Bacterial counts by the pour-plate technique and estimates of the white cell excretion per hour or day, while undoubtedly of d...

This paper deals with the approximate solution ofhnear 4th-order elhptic boundaryvalue problems by thefimte element method For a displacement method using the nonconforming plate element of M orley and for a mixed method known as Herrmann-Miyoshi-scheme quasi optimal Land L^-error estimâtes are denved The proof essenüally uses L-estimâtes for regularized Green's functwns and then disaere amiloq...

This study was designed to evaluate the measuring range and lowest limit of detection of Bacillus endospores in the ambient room air when the Sartorius MD8 sampler, and two different culture methods for bacterial enumeration were used. Different concentrations of bioaerosol were generated inside the test chamber filled with either the high-efficiency particulate air (HEPA)-filtered air or with ...

The presence of pan-resistant bacteria worldwide possesses a threat to global health. It is difficult to evaluate the extent of carriage of resistant bacteria in the population. Sewage sampling is a possible way to monitor populations. We evaluated the presence of pan-resistant bacteria in Israeli sewage collected from all over Israel, by modifying the pour plate method for heterotrophic plate ...

We characterize p-harmonic functions including p = 1 and p = ∞ by using mean value properties extending classical results of Privaloff from the linear case p = 2 to all p′s. We describe a class of random tug-of-war games whose value functions approach p-harmonic functions as the step goes to zero for the full range 1 < p <∞. Résumé On charactérise les fonctions p-harmoniques, y compris les cas ...

Thermophilic actinomycetes are the primary sensitizing agents in farmer's lung disease. We compared dilution pour-plate and spread-plate methods for their usefulness in enumerating thermophilic actinomycetes in moldy silage dust and evaluated the ability of a nonquantitative gravity settling technique to recover thermophilic actinomycetes from moldy silage. Spread plates and pour plates yielded...

A pour-plate method is described for the detection of coagulase production by Staphylococcus aureus. Either Brain Heart Infusion agar or yeast extract-Trypticase soy agar containing swine plasma was the best medium for the detection of coagulase by this method. The advantages of this method and its potential utilization in the clinical laboratory, in food microbiology, and in specialized studie...

Résumé : Nous présentons dans cet article une plate forme logicielle pour générer automatiquement les profils utilisateur nécessaires à l'utilisation d'un système d'information. Cette plate forme est basée sur l'utilisation d'un AGL associé au langage UML et sur des composants JAVA que nous avons développés pour la génération des rôles dans un format XML . Dans une première partie, nous rappelo...
