The emulsion explosive is one of the important industrial explosives. The structural stability of the water-in-oil (W/O) emulsion matrix of an emulsion explosive determines the reliability of its initiation, safety and detonation performance. It is known that the emulsifier is one of the most important factors affecting W/O structural stability. In this paper, several emulsifiers with the funct...

The dynamic breakup of emulsion droplets was demonstrated in double-layered microfluidic devices equipped with designed pneumatic actuators. Uniform emulsion droplets, produced by shearing at a T-junction, were broken into smaller droplets when they passed downstream through constrictions formed by a pneumatically actuated valve in the upper control layer. The valve-assisted droplet breakup was...

 Abstract—The flashover voltage of insulator is relative to the distribution of the electric field. The distribution of the electric field on the insulator is contributed to the shape of insulator. For this, we must optimize the shape of insulator. In this paper, we use FEM, GA and HGAPSO for optimizing the shape of insulator. The tangential electric field and the area of insulator are optimiz...

The present study was carried out to compare the inhibitory effect of alginate coatings containing Zataria Multiflora Boiss essential oil (ZMEO) in two forms of coarse emulsion and Nano-emulsion on the growth of inoculated Escherichia coli O157:H7in beef fillet during 16 days of refrigeration (4 C °). Accordingly, alginate solutions (3%) with different co...

The formation of sulfur trioxide (SO(3)) in coal-fired utility boilers can have negative effects on boiler performance and operation, such as fouling and corrosion of equipment, efficiency loss in the air preheater (APH), increase in stack opacity, and the formation of PM(2.5). Sulfur trioxide can also compete with mercury when bonding with injected activated carbons. Tests in a lab-scale react...

Many bituminous coal mine effluents contain, along with other ions, high concentrations of ferrous iron. This is brought into solution by sulfuric acid produced by the oxidation of sulfuritic material, possibly iron sulfides in part, occurring with bituminous coal (Leathen et al., 1952). The ferrous iron is oxidized by bacteria to the ferric state at a more rapid rate than can be accounted for ...

Chromatin insulators are gene regulatory elements implicated in the establishment of independent chromatin domains. The gypsy insulator of D. melanogaster confers its activity through a protein complex that consists of three known components, Su(Hw), Mod(mdg4)2.2, and CP190. We have identified a factor, Drosophila Topoisomerase I-interacting RS protein (dTopors) that interacts with the insulato...

The paper presents results of sensitivity analysis to crack propagation of a pavement bituminous layered structure using the Finite Element Method (FEM) and Artificial Neural Networks (ANN). The performed preliminary study determined stresses and displacements in the pavement layer system. The pavement structure consisting of asphalt layers, a base layer, subbase and subgrade layers was analyze...

The adsorptive capacity of powdered activated carbon (PAC) is related to the size of the target adsorbate compared with the quantity of pores with sufficient pore diameter into which the adsorbate may diffuse (i.e., the effective internal surface area). The adsorptive capacity of PACs are commonly characterized using aqueous-phase indices such as iodine (I2), methylene blue (MB), p-nitrophenol ...

the effect of addition of qodumeh shahri (lepidium perfoliatum) seed gum on the emulsion properties were investigated in this study. l. perfoliatum seed gum with 0-0.6% (w/w) concentration was used together with 2% (w/w) wpc to emulsify 20% (w/w) corn oil. the emulsion was analyzed for emulsion stability, particle size, specific surface area, particle size distribution and rheological propertie...
