evaluation of mechanical and electrical properties of agricultural products plays an important role in equipment design and optimizing post-harvest operations. among the crops, tomato and its products are the major processing industries in the world and its economic importance is increasing. considering the importance of the quality and various post harvesting uses of tomato, the evaluation of ...

Buckwheat crops are subjected to complex stress during harvest. And there problems such as large deformation, severe brokenness, and high energy consumption of stems the mechanical harvesting, cutting, transporting, threshing, separating cleaning. In this study, properties buckwheat stem harvesting were tested, including tensile, bending, shearing dynamic effects moisture content, position work...

In Italy, the production of Origanum vulgare L. is lower than national market demand, so there an increasing interest in this crop, even if manual harvest and bunch binding represent ca. 60% cost. The aim work to evaluate efficiency, as well working capacity, productivity quality mechanical harvesting by means a reaper-binder designed for cereal forage crops assisted long-reach edge trimmer. fa...

Nanogenerator has been a very important energy harvesting technology through directly deforming piezoelectric material. Here, we report a new magnetic force driven contactless nanogenerator (CLNG), which avoids the direct contact between nanogenerator and mechanical movement source. The CLNG can harvest the mechanical movement energy in a noncontact mode to generate electricity. Their output vo...

Making the most of twists and turns The rise of small-scale, portable electronics and wearable devices has boosted the desire for ways to harvest energy from mechanical motion. Such approaches could be used to provide batteryfree power with a small footprint. Kim et al. present an energy harvester made from carbon nanotube yarn that converts mechanical energy into electrical energy from both to...

High-field 31P NMR (202.2 MHz) spectroscopy was applied to the analysis of 59 samples from three grades of olive oils, 34 extra virgin olive oils from various regions of Greece, and from different olive varieties, namely, 13 samples of refined olive oils and 12 samples of lampante olive oils. Classification of the three grades of olive oils was achieved by two multivariate statistical methods a...

BACKGROUND The thaumatin-like protein (TLP) Ole e 13 in raw olive fruit is responsible for occupational allergy in olive oil mill workers. However, these workers do not experience allergic symptoms after ingestion of edible olive. OBJECTIVES To analyze the presence of IgE-reactive TLP in raw and edible olive fruit and to assess the allergenic potency of both sources. METHODS The content of ...
