In this study, we demonstrated a flexible and self-powered sensor based on piezoelectric fibers in the diameter range of nano- and micro-scales. Our work is distinctively different from previous electrospinning research; we fabricated this apparatus precisely via near-field electrospinning which has a spectacular performance to harvest mechanical deformation in arbitrary direction and a novel c...

In the present study, olive leaf extract, harvested from four seasons, extracted with solvent (methanol and water), was treated by D101 and Sephadex LH-20, and divided into 10 fractions by TLC detection. The antioxidant activity was evaluated using DPPH, superoxide anion scavenging and reducing power assays. Tyrosinase inhibitory activity was also performed with L-DOPA as substrate. On extracti...

A study with controlled field and authentic samples of olives, obtained in similar conditions soil, climate, region, harvest, the same cultivation techniques considering simultaneously different agronomic factors (olive variety, fruit ripening degree, irrigation, organic or conventional production system) is performed to evaluate their influence on quality added value extra virgin olive oil (EV...

Forest structure and species composition in many western U.S. coniferous forests have been altered through fire exclusion, past and ongoing harvesting practices, and livestock grazing over the 20th century. The effects of these activities have been most pronounced in seasonally dry, low and mid-elevation coniferous forests that once experienced frequent, low to moderate intensity, fire regimes....

to study the mechanical and thermal parameters effective on quality and quantity of olive oil towards an extraction of highly pure oil, the velocity in rps of crushing rollers, at two levels of 6 and 12 (rps) along with the temperature of the mixing unit at three levels of 30, 45 and 60°c were taken into account. data, obtaind through a factorial experiment of randomized complete block design (...

Sixteen stands were harvested by either clearcut, shelterwood, group selection, or singletree selection methods. Three of the stands had uneven-aged structure. The other 13 were typical, matrJre, even-aged stands. Hmest intensity @roportion of basal area removed) ranged from 0.27 to 1 .@I. Hanrestcd sites were similar in slope, average diameter at breast height (DBH), and pre-harvest diamcte.r ...

The role of fruit bearing percentage in olive fruit fly infestation is investigated through a simulation model where the spatial law of dispersion distances were modeled via an appropriate exponential law. The dispersal of olive fruit flies was simulated for two distinct cases, an olive grove with no olive fruits and an olive grove with 100% olive fruit bearing. Results showed that when no oliv...
