The use of cutting fluids in machining operations is being carefully scrutinized by industry for several reasons, including its overall cost in the manufacturing process and its impact on worker health. Given the concerns associated with the use of cutting fluids, a number of experimental and analytical research efforts are being conducted to gain an understanding of the role of these fluids in...

Cutting Fluid mist produced during machining operations is receiving increased attention by industry becasue of its adverse health effects. Thus, it is desired to obtain a fundamental understanding of the mechanisms that underlie mist formation. This knowledge can be used as a tool to design machining processes or systems that reduce the formation of cutting fluid mist and hence, the health haz...

Persons undergoing maintenance immunosuppressive treatment (MIST) were shown to be at increased risk for the development of early malignancies, often of cells of the immune system. Very little is known about the late effects of MIST. Some clinical studies indicated an age-related increase in the incidence of plasma-cell disorders, in particular in that of multiple myeloma (MM). In the present s...

A water mist jet for a steam generator of direct contact with a diffusion flame is numerically analyzed in this paper. Numerical simulation is conducted for an 8 Lug-Bolt array in a confined system. The diffusion flame is modelled in the Eulerian Eulerian multiphase approach where the reaction species are oxygen which is injected by a 16.9 mm central nozzle, methane by four peripheral 5.86 mm n...

Hairy roots are genetically transformed roots and highly recommended sources for various secondary metabolites products. Artimisinin is one of them and frequently utilized as pharmaceutical drug for malaria impairment. Hairy roots are fragile tissue and very much sensitive in regarding to culture inside the bioreactor. Designing of bioreactor and optimising the acquired physical and chemical pa...

The influence of greenhouse humidity control on the transpiration rate (λEc), sensible heat flux (Hc) and bulk stomatal conductance (gc) of a soilless rose canopy (Rosa hybrida, cv. First Red) was studied in a greenhouse located in the coastal area of eastern Greece. Measurements were carried out during several days in the summer (i) without air humidity control and (ii) with a mist system oper...

Educational research indicates that the two prevalent approaches to distance education, synchronous and asynchronous, exhibit synergy if combined. Our research addresses how to create the most effective, open source (and therefore robust and inexpensive) software to enable educators to exploit that synergy. The Moodle learning management system provides a high-quality asynchronous online learni...

Numerical simulation is performed in this study to explore filmcooling enhancement by injecting mist into the cooling air with a focus on investigating the effect of various modeling schemes on the simulation results. The effect of turbulence models, dispersed-phase modeling, inclusion of different forces (Saffman, thermophoresis, and Brownian), trajectory tracking, and mist injection scheme is...
