A calculus problem arising in the operation of a storage tank for a chemical processing plant is described. Constructing an appropriate gauge for the storage tank requires computing the volume of water residing inside a tilted cylindrical pipe. The following calculus problem arose in the engineering design of a storage tank facility, and is possibly more interesting and challenging for students...

Different concentrations of oily waste were added in a discontinuous mode and recurrently to anaerobic continuous stirred tank reactors fed with cow manure and food waste. Four continuous stirred tank reactors were run in parallel. A control reactor (R1) received no additional oil and R2, R3 and R4 received increasing concentrations of oil in two different experimental approaches. First, the li...

Chemical sanitizers are routinely used during commercial flume washing of fresh-cut leafy greens to minimize cross-contamination from the water. This study assessed the efficacy of five commercial sanitizer treatments against Escherichia coli O157:H7 on iceberg lettuce, in wash water, and on equipment during simulated commercial production in a pilot-scale processing line. Iceberg lettuce (5.4 ...

Regarding increasing importance of tank wagons and efficiency in fluids transportation, their usage is increasing every day. Thus paying attention to their designs just as dynamic analysis of wagons during travelling time is vitally important. In this task, sloshing coefficient as prominent parameter in tank wagons designing has been investigated. To ease of efficient design, theses parameters ...

An important aspect of extraction using an organic solvent that is often ignored in many laboratory scale studies is thorough solvent recovery. Although most of the solvent can be recovered with a centrifuge, the solvent left on the ‘dry’ stream must be evaporated. A custom built pilot-scale settling tank was used to separate maize particles from ethanol extracts into water with little dilution...

PURPOSE Addressing important but complex research questions often necessitates the creation of innovative mixed methods designs. This report describes an approach to developing research designs for studying important but methodologically challenging research questions. METHODS The Methodological Think Tank has been held annually in conjunction with the Primary Care Research Methods and Statis...
