In Part 1 of this paper a model was developed to describe the formation mechanisms and dynamic behavior of cutting fluid mist. This part of the paper focuses on an experimental investigation of the mist generated by the interaction of the fluid with the rotating cylindrical workpiece during a turning operation and the simulation of the dynamic behavior of the mist droplets, resulting in the pre...
We developed new processes which can collect and detect rapidly airborne pathogens such as the avian flu virus for the pandemic prevention. The fluorescence antibody technique is known as one of high-sensitive detection methods for viruses, but this needs up to a few hours to bind sufficient fluorescence dyes to viruses for detection. In this paper, we developed a mist-labeling can detect subst...
Building a group of agents which can work effectively as a team is more than just merely putting individual agents together. Agents working in a team require the abilities to plan, communicate and coordinate with one another. Furthermore, systems in which agents are simply equipped with precomputed coordination plans will fail to work in complex, dynamic environments. Thus it is extremely diffi...
Mist-assisted film cooling has exhibited great potential for efficient of a turbine blade. Trench structures can significantly affect the performance air, while their impact on adhesion characteristics droplets and thus mist-assisted is unclear. This work highlights combination these two aspects by exploring improvement trenched holes with shaped lips using three-dimensional computations. The r...
OBJECTIVE To systematically review the risk of mortality associated with long term use of tiotropium delivered using a mist inhaler for symptomatic improvement in chronic obstructive pulmonary disease. DATA SOURCES Medline, Embase, the pharmaceutical company clinical trials register, the US Food and Drug Administration website, and ClinicalTrials.gov for randomised controlled trials from ince...
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...
