Land use and land cover across 28 sub-basins within the Cosumnes Watershed, CA (1989 km) were correlated to nitrate-N and total suspended solids (TSS) loading between water years 1999 and 2001. The impact of human development on stream water quality was evident as both agricultural area and population density predicted TSS loading in a linear mixed effects model. In contrast to the TSS model, t...

Every acceleration or deceleration causes inertia forces and as a consequence elastic waves. Of course, such dynamic loading situations often occur in structural applications of materials. The consequences of such dynamic loading on designing with ceramics are considered on the example of a new dynamic tension test. First, the test device is described, and the resulting loading situation is car...

fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...

one of the methods for the improvement of soil against the tensile stresses is using the artificial supplements in soil such as metal belts or nets, polymer materials and natural fibers. technically this method is called the reinforced of soil.  when a pavement is located on soft soil, great deformations can occur as a result of the crossing of traffic load in superstructure layers of the body....

Identification of functional programmable mechanical stimulation (PMS) on tendon not only provides the insight of the tendon homeostasis under physical/pathological condition, but also guides a better engineering strategy for tendon regeneration. The aims of the study are to design a bioreactor system with PMS to mimic the in vivo loading conditions, and to define the impact of different cyclic...

When designing wheelchairs for use as motor vehicle seats, special design criteria must be followed to assure the crash safety of the wheelchair user. Failure of seating system components under crash loading conditions could lead to serious injury or fatality. In this study, seat and seat-back loading in a frontal crash are explored using computer simulation techniques . A previously validated ...
