The quantum dynamics of transport networks in the presence of noisy environments has recently received renewed attention with the discovery of long-lived coherences in different photosynthetic complexes. This experimental evidence has raised two fundamental questions: firstly, what are the mechanisms supporting long-lived coherences; and, secondly, how can we assess the possible functional role...

Hazelnut cultivation is widely practiced in our country. One of the major problems hazelnut powdery mildew disease on tree leaves. In this study, early detection with YOLO model based machine learning was tested a unique data set. Object image, which applied plant diseases, has been for diseases. According to results obtained, it seen that can be detected image. network trained Yolov5 model, di...

consumption of food containing cholesterol and saturated fatty acids such as butter can increase serum cholesterol and cause cardiovascular diseases. therefore many efforts have been done for decreasing these constituents in foods. in this study, hazelnut and walnut powders were added to butter samples in amounts of 0 (not enriched sample), 10, 20 and 30% for evaluation of chemical characterist...

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...

BACKGROUND Most reports in the medical literature on food allergy mortality are related to peanut and tree nut. There is limited knowledge regarding these reactions and often only a partial medical history is described. OBJECTIVE To record and characterize all known cases of mortality due to food allergy in Israel occurring during the period 2004-2011. METHODS All cases of food allergy-rela...
