Abstract. Detecting immature green citrus at an early stage for yield forecasting can help growers expect how many fruit they can harvest at the end of the year. Also, it can provide an in-field spatial variability of fruit that can be used for providing site-specific management of citrus trees to increase yield and profit. Yield forecasting using the machine vision technology has been a promis...

Over-harvesting of forestry resource, primarily trees, through illegal logging has been exceptionally regular for decades. In the context of this worldwide issue, a mathematical model considering the joined impact of legal and illegal logging of trees from forestry biomass using delay-driven ordinary differential equations is proposed. For the set of equations, we have taken immature, mature fo...

Knowledge of green turtle ( Chelonia mydas ) foraging ecology in the northwestern Gulf Mexico (GOM) is critical as populations begin to recover from heavy harvesting prior centuries. We present a comprehensive long-term assessment diets carcasses salvaged 1987 2014 along Texas coast. Digestive tract contents were examined 420 turtles, ranging size 7.3 86.0 cm straight carapace length (SCL max )...

shipped long distances and supply was dependent on local production areas. Demand for year-round, inexpensive produce has led to consolidation of production where temperatures are warm, sunshine is plentiful, and labor is cheap. In most cases, produce is now shipped long distances before being consumed. Tomatoes grown in Mexico are trucked 3,500 miles, bananas grown in Ecuador travel 6,000 mile...

the aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting lime fruit (c. aurantifolia). a tractor mounted limb shaker with adjustable shaking frequency and amplitude, powered by the tractor power-take-off shaft was designed and developed for this study. the rotating input power was transmitted to the shaker flywheel through a multiple sheave v...

Singlet-singlet annihilation experiments have been performed on trimeric and aggregated light-harvesting complex II (LHCII) using picosecond spectroscopy to study spatial equilibration times in LHCII preparations, complementing the large amount of data on spectral equilibration available in literature. The annihilation kinetics for trimers can well be described by a statistical approach, and an...

A light-harvesting complex composed of a π-stacked multichromophoric array in a DNA three-way junction is described. The modular design allows for a ready exchange of non-covalently attached energy acceptors.

We present a simple method to resolve discrete intensity shifts from time-resolved single-molecule emission data. This new method uses multiples of the standard deviation of the measured intensities that are integrated into short time bins. By applying the technique to trimeric units of the main light-harvesting complex (LHCII) of plants, it is shown that the amount of information that can be e...

Redox-regulated reversible phosphorylation of the light-harvesting complex II (LHCII) controls the excitation energy distribution between photosystem (PS) II and PSI. The PsaL and PsaH subunits of PSI enable the association of pLHCII to PSI. Here, we show that the failure of the psal mutant to dock pLHCII to PSI induces excessive phosphorylation of LHCII, primarily due to a marked downregulatio...

The object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. The evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. The results revealed that the effect of soil moisture content was only significant on...
