Aggregates constitute major part of the pavement structure. The engineering properties of the aggregates, as well as its shape (i.e. form and angularity) and texture, substantially affect the overall performance of the pavement (Kuo and Freeman 1998, Maerz 2004). A number of researchers reported that form and surface texture of aggregates have significant effect on the mechanical property of th...

Wood is an amazing combination of polymers that exhibits both strength and durability as a structural material. Nevertheless, from the time it is formed in the tree, wood is subject to deterioration by a variety of agents. Damage ranges from relatively minor discolorations caused by fungi or chemicals to more serious decay and insect attack. Wood degradation is beneficial in the ecosystem, retu...

The implementation of WMA is becoming more widespread with a growing number of contractors using various WMA technologies. Early research suggests WMA may be more susceptible to moisture damage than traditional HMA mixes. Asphalt performance tests can be a good way of measuring material responses that can be correlated with pavement performance. It is important for owner/agencies to know that t...

In a previous work, we have developed a perflouropolyether (PFPE) lubricant droplet-filled SU-8 composite which promotes bonding between the molecules of SU-8 and PFPE and provides excellent boundary lubrication. The SU-8 + PFPE composite has enhanced the wear durability of SU-8 by more than four orders of magnitude. In this work, the same SU-8 + PFPE composite was used to fabricate a stand-alo...

INTRODUCTION First antiretroviral therapy (ART) is often switched to simpler, more potent or better tolerated regimens (1, 2). Although discontinuation rates are frequently studied, the durability of regimens is rarely approached. MATERIALS AND METHODS Retrospective study with the following objectives: analyze first ART schemes and their durability in naive patients with chronic HIV-1 and 2 i...
