abstract suspended sediment resulted from distributed soil erosions facilitates soil nutrients transportation and influences soil depletion. soil erosion plays a key role in loss of organic matter and therefore study of the relationship between organic matter and soil erosion processes and soil nutrient loss is very important. the present case study was conducted in kojour educational forest wa...

We have investigated electronic cooling of suspended nanowires with SINIS tunnel junction coolers. The suspended samples consist of a free standing nanowire suspended by four narrow (∼ 200 nm) bridges. We have compared two different cooler designs for cooling the suspended nanowire. We demonstrate that cooling of the nanowire is possible with a proper SINIS cooler design.

Based on the small deflection beam theory, bending equation with axial tension of suspended pipe partially buried in the linear elastic soil is established. And the corresponding boundary conditions are given according to the stress and deformation characteristics of suspended section and buried section. Then deflection equation for the suspended section is deduced. Afterwards, the stress and c...

Modeling of stream flow–suspended sediment relationship is one of the most studied topics in hydrology due to itsessential application to water resources management. Recently, artificial intelligence has gained much popularity owing toits application in calibrating the nonlinear relationships inherent in the stream flow–suspended sediment relationship. Thisstudy made us of adaptive neuro-fuzzy ...

In this work, a novel steady-state electro-Ramanthermal (SERT) technique is developed to characterize the thermal transport in one-dimensional micro/nanoscale materials. The SERT technique involves steady-state joule heating of a suspended sample and measuring its middle point temperature based on the temperature dependence of the Raman shift peak intensity. The thermal conductivity is determin...

Two-dimensional (2D) optical scanners with large-area mirrors and large angular rotation are of great interest for applications in display, printing, optical scanning and sensing, optical data storage, and free-space optical links between satellites. The Micro-Electro-Mechanical System (MEMS) technology is very attractive to reduce the size, weight, and complexity of the optical scanners. Sever...

Within the quest for direct band-gap group IV materials, strain engineering in germanium is one promising route. We present a study of the strain distribution in single, suspended germanium nanowires using nanofocused synchrotron radiation. Evaluating the probed Bragg reflection for different illumination positions along the nanowire length results in corresponding strain components as well as ...
