www.pharmtech.com n the manufacture of many pharmaceutical products, dry-particle blending is a critical step that directly affects content uniformity. Tumbling blenders—a common way to mix granular constituents—are hollow containers attached to a rotating shaft; the vessel is partially loaded with materials and rotated. Their main advantages are large capacities, low-shear stresses, flexibilit...

Title of Document: FAMILY STRUCTURE DIFFERENCES IN MATERNAL TIME WITH CHILDREN: DISPARATE SOCIAL STRUCTURAL LOCATIONS OR DIFFERENT PROPENSITIES TOWARDS MOTHERING? Sarah M. Kendig, M.A., 2007 Directed By: Professor and Chair, Suzanne M.

This paper describes a web-enabled tool capable of generating high quality videos and images from multibody dynamics simulation results. This tool, called Chrono::Render, uses the Blender modeling software as the front end with Pixars RenderMan used to create high quality images. Blender is a free and open source tool used to create and visualize 3D content and provides a robust plugin framewor...

One of the promising ways to tame a tornado is to inject dust into it. Somewhat counter-intuitively, injecting coarse dust only makes the tornado stronger, while injecting fine dust can indeed help in the taming. This difference has been explained by a mathematical analysis of the corresponding equations, but (in contrast to the usual physics practice) this mathematical analysis has not yet bee...

manufacturers around the globe are competing for the identification of innovative value propositions to survive in the competitive and complex market. this paper is intended to investigate implementation of value engineering (ve) technique into the product design concept for necessary changes in design of the humidifier system in order to lower unnecessary costs and to increase quality of the p...

Inadequate gas conditioning during non-invasive ventilation (NIV) can impair the anatomy and function of nasal mucosa. The resulting symptoms may have a negative effect on patients' adherence to ventilatory treatment, especially for chronic use. Several parameters, mostly technical aspects of NIV, contribute to inefficient gas conditioning. Factors affecting airway humidity during NIV include i...

Thirty five printers who had work related wheeze, chest tightness, or breathlessness kept two hourly records of their peak expiratory flow for at least two weeks. They all worked in a factory supplied by air from contaminated humidifiers. The peak flow records showed consistent work related deterioration in 15 workers, nine of whom had a diurnal variation in peak flow exceeding 20%. Ten workers...
