Thermal barrier coatings were prepared on magnesium alloy substrate by plasma spraying, and thermal shock test, test arc wind tunnel carried out. The failure mode, microstructure phase transition of coating after analyzed SEM XRD change temperature rise rate during is means measurement. analysis results show that the structure sprayed surface consistent before shock, no occurs spraying shock. m...

gaz is one of the traditional food products. ingredient of gaz has certain differences compared with other sweets & snacks, which in the preparation of them no oils, starch and flour is used. adverse color, taste and odor in gaz may has been created by oxidation in nuts at store condition. on the other hand, gaz becomes dry in inappropriate packaging at areas with low humidity and becomes soft ...

high solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of cloisite 30b (7 wt% and 10 wt%) were kinetically investigated. gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. results showed that by increasing the solid content; the average diameter of poly...

Numerical simulation of migration of chemical substances from HDPE into foods(simulants)is performed based on the finite element method(FEM). The results show that concentration of migrants in foods at equilibrium increases with the increase of its initial concentration in packaging. Diffusivity of migrants is key to migration dynamics. Partition coefficient represents ration of concentration i...

The pulmonary blood-gas barrier is an extraordinary structure because of its extreme thinness, immense strength, and enormous area. The essential components of the barrier were determined early in evolution and have been highly conserved. For example, the barriers of the African, Australian, and South American lungfish that date from as much as 400 million years ago have essentially the same st...

Making use of data from the Household, Income and Labour Dynamics in Australia (HILDA) survey coupled with air pollution data generated by The Air Pollution Model (TAPM), this paper employs the life satisfaction approach to estimate the cost of air pollution from human activities in South East Queensland. This paper offers at least three improvements over much of the existing literature: (1) wi...

according to statistics released by agricultural insurance fund (aif) less than 4 million acres out of 90 million acres has been covered by pastures insurance. this observation along with several facts motivated authors to study possible barriers which pastures insurance has been encountered in practice. the research population included all the experts in agricultural insurance fund. small popu...
