Accurate calculation of the minimum fluidization velocity makes it possible to reduce raw material losses due use excessively high or low air velocities. This is particularly true for impingement fluidization, which little studied, especially when treating parachute-shaped material. paper focused on determining drag coefficient cauliflower florets, mushrooms, and broccoli. Analysis critical par...

OBJECTIVES The aim of this study was to determine the influence of non-ionisable excipients hydroxypropyl-β-cyclodextrin (HPβCD) and poloxamers 407 and 188 on the supersaturation and precipitation kinetics of ibuprofen, gliclazide, propranolol and atenolol induced through solution pH shifts using the CheqSol method. METHODS The drug's kinetic and intrinsic aqueous solubilities were measured i...

We evaluated the use of strain gauge plethysmography (SGP) for the assessment of orthostatic fluid shifts during head up tilt (HUT). Subjects wore a parachute harness fixed to the tilt table to avoid muscle tension in the lower limbs during HUT. 22 Healthy subjects (9 women) were tilted for 5 minutes. Calf volume changes as measured by SGP, surface EMG, heart rate and blood pressure were measur...

Our laboratories are examining injuries and deaths resulting from mechanical forces applied to aircrew members in the course of Department of Defense aviation operations. In this paper we report only on bodily injuries sustained during ejection from US Air force, aircraft for the fiscal years 1981-1996, that is, major injuries and fatalities resulting directly from seat acceleration forces, fro...

Parachute mitral valves (PMVs) and parachute-like asymmetric mitral valves (PLAMVs) are associated with congenital anomalies of the papillary muscles. Current imaging modalities cannot provide detailed biomechanical information. This study describes computational evaluation techniques based on three-dimensional (3D) echocardiographic data to determine the biomechanical and physiologic character...

I study optimal incentive contracting when a temporary project is overseen by a firm with access to two channels of information about the project’s state a noisy public news process, and the reports of a manager possessing superior private information. The firm faces the decision problem of when to wrap up the project, as well as the agency problem of a manager with borrowing constraints and in...
