in this research, the numerical method of computational fluid dynamics and dimensionless parameter of froude number have been applied to determine the flow regime over ogee spillways.froude number is a dimensionless dynamic parameter calculated using the square root of the ratio of inertia force and gravitational force. considering that the study of the regimes of flow over hydraulic structures...
background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocalcin and cross laps. the fok i polymorphism in ...
the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
A 2-D version of the asymmetric exclusion model for granular sheared flows is presented. The velocity profile exhibits two qualitatively different behaviors, dependent on control parameters. For low friction, the velocity profile follows an exponential decay while for large friction the profile is more accurately represented by a Gaussian law. The phase transition occurring between these two be...
the hydrograph at watershed outlet can be expressed as hydrological response of watershed to geomorphological behavior. in present study with the aid of the gis and the concept of instantaneous unit hydrograph, the watershed response was simulated. in present physical method, the iuh is derived from three parameters of time of concentration, storage coefficient and time-area curve of the basin....
Für die Ansteuerung einer Elektronischen Nase wurde eine Echtzeitsteuerung mittels Ada und dem Ravenscar-Profil entwickelt. Ziele waren hierbei der Entwurf und die Umsetzung eines mehrstufigen abstrakten Softwaremodells und eine Abbildung der nebenläufigen Aktivitäten zur Steuerung der Elektronischen Nase. Letzteres wird durch die Verwendung von Ada erreicht, denn das Ada Laufzeitsystem ermögli...
