A study was conducted to analyze the performance of 3 electrostatic (Electrolon BP-2.5, Spectrum Electrostatic 4010, and Spectrum Electrostatic head on a Stihl 420) and 2 conventional (Buffalo Turbine CSM2 and Stihl 420) sprayers for barrier sprays to suppress an adult mosquito population in an enclosed area. Sprayer characteristics such as charge-mass ratio, air velocity, flow rate, and drople...

In the combustion chambers of gas turbine engines, ZrO2-8wt.%Y2O3 (YSZ) TBCs are commonly applied by air plasma spray (APS) using Ar-/H2-based plasmas via legacy torches. Alternatively, N2/H2 could be used with potential increasing overall deposition efficiency (DE) and hence reduce consumption high-value feedstock powder. Also, DE, spraying time would reduced, thereby providing another contrib...

Submodels are developed for injection, evaporation and wall impingement of a liquid LPG spray. The injection model determines the quality of fuel as two-phase choke flow at the nozzle exit. Wind tunnel experiments show the spray penetration more sensitive to ambient flow velocity than to injection pressure. Most evaporation occurs during choking, while heat transfer from surrounding air has a n...

Plasma spray process is one of the most versatile thermal spray deposition processes. There are great number of parameters that influence the quality and characteristic of deposited coating and their values must be defined precisely for each type of coating and used equipment individually. A review of the technology developed for deposition of ferrous-based powder spray (Fe-1.3Cr-1.5Mn-1.2C0.3N...

• Sitz Baths — Fill your tub with about 6 inches of warm water and sit in the tub for 10 to 15 minutes at least 2 to 3 times each day. Th e warm water increases the fl ow of blood to the perineum, which helps the area heal. • Rosemary Tea — Make a tea with dried rosemary leaves by pouring very hot water over about 3 tablespoons of the leaves. You can buy these leaves in bulk at many grocery sto...
