We use multivariable feedback control to reduce variations in flow and back-pressure associated with two industrial separator units forming part of an edible oil refining line. This provides plant operators with a mechanism for increasing process yield without reducing product quality. Actuator limits are a natural consideration in the controller design since increased production rates require ...

In infants, lactose ingestion induces diarrhoea that may threaten life. In children, this consumption leads to a discomfort sensation and the child learns to identify the responsible sources of that and banish them of his diet. However, in the course of teenage and moreover in adult age, it is usual and surprising to record that persons who consume again milk products do not suffer from discomf...

 In this research, a numerical modeling was utilized to calculate the stresses caused during thermal cycling in a functionally graded thermal barrier coating (FG - TBC). The temperature – dependent material response of this protective material was taken into account and the effects of thermal cycle and interface morphology of the ceramic / metallic layer in functionally graded coating system wa...

The thermal barrier coatings (TBCs) by gas tunnel-type plasma spraying exhibited ceramic-composite features consisting of a host oxide matrix ceramic with an embedded second phase material. The densities of the composite TBC were found to be higher than those sprayed with 100wt% ZrO2 or Al2O3. In the coatings produced with powder mixtures of 50wt%, the embedded splats are found to have a relati...

Problems of adherence of thermal protective coatings to aerospace structures have become important with their use on vehicles such as the space shuttle and for jet engine turbine blades. In these structures a dielectric coating which acts as a thermal barrier. is bonded to a conductive substrate. Failure of these coatings to adhere to the substrate can result in catastrophic failure of the vehi...

Rationale Food Allergy is a growing public health concern. There is observational evidence that exposure to food allergens across a disrupted skin barrier can lead to food sensitisation (FS) and food allergy (FA). This mechanism of action has subsequently been proven in murine studies. We sought to ascertain whether a non invasive measurement of skin barrier function at 3 time points in early i...

Yttria-stabilized zirconia (YSZ) has been used as a thermal/environmental barrier coating for gas turbine engine blades. Current methods of fabrication include air plasma spraying (APS) and electron-beam physical vapor deposition (EB-PVD). The APS technique results in a coating that loses effectiveness with thermal cycling. The EB-PVD technique deposits a columnar microstructure which accommoda...

After washed with soap and rinsed in UPSW for 2 weeks, severe dermatitis of NC/Tnd mice were reduced as well as TEWL. On the other hand, dermatitis in NC/Tnd mice rinsed in tap water became worse. Plasma total IgE was increased in mice that were immunized with metallic soap. Conclusions: UPSW protected skins from residue of metallic soap. Metallic soap has antigenic activity and increased plasm...
