Second-generation trapezoidal sheeting, characterised by longitudinal stiffeners in webs and flanges, is loaded near a support concentrated force bending moment. Currently, design codes predict related failure by: (a) determining the ultimate moment via effective width approach or Direct Strength Method (DSM); (b) finding web crippling load curve-fitted formula; (c) using an interaction rule to...

BACKGROUND & OBJECTIVES Insecticide incorporated plastic sheeting is a new technology to control mosquitoes in emergency shelter places and also temporary habitations in different locations. Therefore, field studies were conducted to assess the efficacy of ZeroFly plastic sheeting treated with deltamethrin on prevailing disease vectors Anopheles culicifacies and An. fluviatilis and its impact o...

Erythemal UV exposure for individuals involved in outside activities are affected according to surrounding structures in an urban environment. Occupational UV exposure is likely to increase by the effects of surrounding structures. UV reflections from surrounding structures, in this case vertical metal walls, were investigated for their influence on erythemal UV exposure in the southern hemisph...

Liquid metal assisted cracking (LMAC) and so-called microcracking are limiting the application of hot-dip galvanized boron steels in direct press hardening process. This study addresses role steel hardenability on behavior ZnFe-coated (galvannealed) 22MnB5 22MnMoB8. Several soaking times forming start temperatures range 800–520 °C examined using a laboratory equipment with hat-profiled tool. Th...
