SOME CHARACTERISTICS OF THE RESULTANT AIR FLOW FROM MOTIONS INDUCED BY VENTILATION AND HEAT SOURCE IN A TWO-DIMENSIONAL ENCLOSURE

Some characteristics of the resultant air flow from motions induced by ventilation and heat source in a two-dimensional enclosure

Ventilated air flow in an enclosure is often unsteady (turbulent) at even very low Reynolds number (Re).Meantime natural convection in a box is stationary motion at large enough Rayleigh number (Ra).This paper deals with the interaction between two those flows in a two-dimensional room.The room has one inlet and one or two outlets.A heat replica be

Oxygen transfer rate during the production of alginate by Azotobacter vinelandii under oxygen-limited and non oxygen-limited conditions

Abstract Background The oxygen transfer rate (OTR) and dissolved oxygen tension (DOT) play an important role in determining alginate production and its composition; however, no systematic study has been reported about the independent influence of the OTR and DOT.In this paper, we report a study about alginate production and the evolution of the mol

Pegbovigrastim Treatment around Parturition Enhances Postpartum Immune Response Gene Network Expression of whole Blood Leukocytes in Holstein and Simmental Cows

Pegbovigrastim is a commercial long-acting analog of bovine granulocyte colony-stimulating factor (rbG-CSF) that promotes the increased count and functionality of polymorphonuclear cells in dairy cows around the time of parturition.We hypothesized that pegbovigrastim administered to periparturient cows at approximately seven days before parturition
