Guilan Province is the biggest hazelnut producer in Iran. Over 70% of hazelnut production cost is due to its manual harvesting. Therefore, study on all aspects of its cultivation mechanization is necessary to sustain its production. This study focused on identifying factors that affect the development of hazelnut harvesting mechanization in Guilan Province, Iran, using a three-round Delphi tech...

The abundant mechanical vibration energy in bridge road environment can be converted into electric energy by using the piezoelectric energy harvest technology, which could be an efficient way to provide energy required by the wireless sensor network in the bridge condition monitoring system. An autonomous energy harvesting system has been designed based on cantilever beams for sensing and acqui...

I investigate the role of regulation and factor prices in the rapid, widespread adoption of mechanical harvesting technology by Brazilian sugarcane growers. I use workerand establishment-level data to test the effect of regulation using complementary regression discontinuity and difference-in-differences approaches. I find that regulation is, at best, a partial explanation, accounting for no mo...

Direct tensile mechanical loading of an individual single-crystal BaTiO(3) nanowire was realized to reveal the direct piezoelectric effect in the nanowire. Periodic voltage generation from the nanowire was produced by a periodically varying tensile mechanical strain applied with a precision mechanical testing stage. The measured voltage generation from the nanowire was found to be directly prop...

BACKGROUND Annexin V staining is a common tool in apoptosis analysis. However, in adherently growing cell lines, substantial experimental bias could be introduced by membrane damage during the harvesting process. We investigated the influence of three different harvesting methods on the cell membrane integrity of six malignant cell lines. MATERIALS AND METHODS Six malignant cell lines were de...

In Ethiopia, harvesting cereal crops is one of the major attentive agricultural operations in agriculture production, which demands a considerable amount labor. There are significant issues with labor costs and availability during harvest wheat crops. Therefore, it crucial to use mechanical technologies assure timely reduce field losses order increase farm productivity. The objective this study...

The huge number of electronic devices called the Internet Things requires miniaturized, autonomous and ecologically sustainable power sources. A viable way to these is by converting mechanical energy into electrical through electro-active materials. most promising widely used materials for harvesting are piezoelectric materials, where main one toxic or not biocompatible. In this work, we focus ...
