Corrugated paperboards are used for packaging because of their high strength-to-weight ratio, recyclability, and biodegradability. paperboard consists a liner corrugated medium has an orthotropic sandwich structure with unique characteristics each direction owing to its flute shape. In this study, finite element analysis (FEA) was performed on the flat crush behavior based type. The stress-stra...

Abstract Wild oat is a herbicide resistance-prone global weed species that causes significant economic losses in dryland and horticultural agriculture. As result, there has been research effort to control this species. A major impediment the seed coat-mediated dormancy of wild oat, which requires labor-intensive incision or puncturing coat initiate germination. This study defines most efficient...

Background and Aim: High consumption of carbonated diet soda is the most common etiologic factor for dental erosion. The purpose of this study was to evaluate the microhardness of the enamel surface eroded by cola after treatment with Remin Pro and neutral sodium fluoride. Materials and Methods: This in vitro experimental study was performed on 20 extracted premolars with no corrosion, abras...

This research aims to evaluate the effects of seed scarification on five perennialAstragalus species including A. effusus, A. vegetus, A. subsecundus, A. brevidens and A.cyclophyllon in the field conditions. Seeds were sown after scarification with sandpaper byhand in the field of Homand Absard Rangeland Research Station, Damavand, Iran in autumnin 2008. The seeds were sown using split plot des...

Wall-roughness induces extra drag in wall-bounded turbulent flows. Mapping any given roughness geometry to its fluid dynamic behaviour has been hampered by the lack of accurate and direct measurements skin-friction drag. Here Taylor-Couette (TC) system provides an opportunity as it is a closed allows directly reliably measure skin-friction. However, wall-curvature potentially complicates connec...

From the past to present, plastic materials are used extensively in all areas of industry, thanks their shaping capabilities. Especially last 10 years, with proliferation desktop type 3D printers additive manufacturing sector, thermoplastics have become most widely material. Therewith, assembly produced by this method has gained so much importance. Since low surface energy, there difficulties p...

Developing a practical strategy to fabricate an anti-abrasion and durable superhydrophobic wood surface with ultraviolet (UV) resistance has great significance for expanding the application of natural wood. In this study, robust layer hierarchical micro/nano-roughness structure was modified on through in-situ mineralization polymerization using simple sol–gel method along efficient electron bea...

Abstract Reckless discharge of industrial wastewater and domestic sewage as well frequent leakage crude oil have caused serious environmental problems posed severe threat to human survival. Various nature inspired superhy-drophobic surfaces been successfully applied in oily water remediation. However, further improvements are still urgently needed for practical application terms facile synthesi...
