SPEX2: automated concise extraction of spatial gene expression patterns from Fly embryo ISH images

Motivation: Microarray profiling of mRNA abundance is often ill suited for temporal–spatial analysis of gene expressions in multicellular organisms such as Drosophila. Recent progress in image-based genome-scale profiling of whole-body mRNA patterns via in situ hybridization (ISH) calls for development of accurate and automatic image analysis systems to facilitate efficient mining of complex temporal–spatial mRNA patterns, which will be essential for functional genomics and network inference in higher organisms

Simulation of air movement in a cinnamon chips dryer using computational fluid dynamics

Non uniformity of final moisture content of the product being dried is the main drawback of tray dryers. The difficulty in maintaining the uniform air velocity throughout the drying chamber had been identified as the main reason for this non uniform drying. A CFD model was developed to analyses the velocity and temperature profiles of a cinnamon chips dryer by using STAR CD. The modeled data for air velocities had been experimentally verified for velocity distribution within the drying chamber. The CFD analysis revealed the presence of non uniform air re-circulating zones at the inlet air duct and drying chamber, which results in non uniformity of air velocities. Previously reported variations of moisture level in dried cinnamon chips at different tray locations were compared with modeled velocity distributions of the present study. The results indicated that the variations in the moisture level of dried cinnamon chips were directly attributed to the non uniform air distributions at different tray location
