 BLENDING: It is most important step for manufacturing of solution dosage form. High speed of mixing may introduce air into the product and slow mixing may not form a satisfactory product.  For mixing step, both mixing time and speed should be evaluated for API and Excipients.  Mixing might produce particle size reduction or polymorphic conversion  During mixing some other factors like typ...

Experiments in dogs showed that the high levels of cellular aggregation and trauma caused by cariodtomy suction can be considerably reduced by the avoidance of air aspiration. A hypothesis is proposed to explain this on the basis of shear stresses in the inlet cannula. Roller pump suction was also found to be slightly more traumatic than vaccum suction, but contact of the blood with the pericar...

BACKGROUND Epidural intracranial hematoma is one of the most common complications of surgeries for intracranial tumors. The non-regional epidural hematoma is related to severe fluctuation of the intracranial pressure during the operation. The traditional management of hematoma evacuation through craniotomy is time-consuming and may aggravate intracranial pressure imbalance, which causes further...

Present paper focuses on design and simulation of an inset fed rectangular microstrip patch antenna for GPS applications. The proposed is designed at frequency 1.9 GHz which comes in L-Band region simulated using Electromagnetic Simulator such as HFSS software with three different dielectric substrates comparing their performance characteristics gain, bandwidth, beam width, VSWR return loss. re...

in this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. to achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. the length of gasper air flow was compared with the distance between gasper outlet and...

Assuming spherical symmetry we analyse the dynamics of an inhomogeneous dark radiation vaccum on a Randall and Sundrum 3-brane world. Under certain natural conditions we show that the effective Einstein equations on the brane form a closed system. On a de Sitter brane and for negative dark energy density we determine exact dynamical and inhomogeneous solutions which depend on the brane cosmolog...
