The development of onychomycosis or tinea pedis was significantly related to type 2 DM, increasing age, and male gender. The most common isolate was Trichophyton rubrum. The isolation and identification of the fungus is important to the effective management of tinea pedis and onychomycosis in diabetes patients because non-dermatophyte fungi can cause these infections.
In this paper an attempt has been made to study the use of microsilica on the properties of self-compacting-concrete (SCC) such as compressive strength, splitting tensile strength, flexural strength, ultrasonic pulse velocity (UPV) and microhardness when exposed to different atmospheric steam curing temperatures. The influence of microsilica as partial replacement of cement on the properties of SCC is investigated. In this study, mixes were prepared with three percentages of microsilica ranging from 5% to 10% and one controlled mixture without microsilica was also prepared for comparison. The specimens of each concrete mixture were heated up to different temperatures (65 • C, 70 • C and 75 • C). The variables included were the temperature effects (65 • C, 70 • C and 75 • C) using Cem I 42.5. SCC mixes enhanced atmospheric steam curing compressive strength ranging from 29.20 to 38.50 MPa, flexural strength ranging from 4.95 to 6.56 MPa and splitting tensile strength ranging from 1.18 to 1.63 MPa. Test results clearly show that there is little improvement in the compressive strength within temperature range of 70 • C as compared to 65 and 75 • C, although there is little reduction in splitting tensile strength ranging from 65 to 75 • C and with the increase in percentage of microsilica. However, the rate of splitting tensile strength and flexural strength was higher than that of the compressive strength at elevated temperatures and with the increase in percentage of microsilica. In this paper, scanning electron microscopic (SEM) observations were also made to explain the observed residual compressive strength increase between 65 • C, 70 • C and 75 • C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
