198 lactic acid bacteria (lab) were isolated from iranian milk samples. almost all isolatedlab showed inhibitory activity towards e. coli and s. aureus as gram negative and grampositive indicators, respectively. no role was observed for hydrogen peroxide in the activity ofall isolated strains while organic acids proved a prominent role in all detected inhibitoryactivities. within isolated lab, ...

this paper has two objectives. first, it establishes a model for scoring the access to pharmaceutical services. second, it develops a model for measuring socioeconomic indicators independent of the time and place of study. these two measures are used for measuring equity in access to pharmaceutical services using concentration curve. we prepared an open-ended questionnaire and distributed it to...

oral ph sensitive drug delivery systems are of utmost importance as these systems deliver the drug at specific part of the gastrointestine (gi) as per the ph of gi, resulting in improved patient therapeutic efficacy and compliance. the ph range of fluids in various segments of the gi tract may provide environmental stimuli for drug release. the aim of this study was to design buoyant beads cont...

This paper is devoted to the study of geometries of inhomogeneities with minimum strain or stress concentration. The solutions are achieved by the indirect method of first deriving lower bounds and then constructing the geometries to attain the lower bounds. In particular, we show that a new class of geometries, namely, E-inclusions and periodic E-inclusions, are the optimal geometries with min...

A new ascidian species belonging to the Botryllinae was discovered in the Gulf of Taranto (South Italy). This new species was collected in different seasons over a period of several years, which allowed information about its biology to be obtained. The new species presents large zooids arranged in ladder systems. The zooids have several rows of stigmata, the second one complete, ovary posterior...
