Grape composition plays important role for wine grapes in terms of wine grape quality. Besides, monoterpenes are a chemical class of compounds present in many highly aromatic Vitis vinifera L. cultivars belonging to Muscat family and some other special cultivars. One of these special grape cultivars is Sauvignon Blanc, and in this study, cluster thinning and its treatment times were used for a ...

OF THE DISSERTATION Various Geometric Aspects of Condensed Matter Physics by Zhenyu Zhou Doctor of Philosophy in Physics Washington University in St. Louis, 2013 Professor Alexander Seidel, Chairperson Geometric aspect of condensed matter has arouse a lot of interests in recent years. The idea of Berry phase is highly appreciated in various systems. We explored the geometric features of two spe...

The research was carried out at University of Belgrade Faculty Agriculture experimental station “Radmilovac” on table grape Victoria cv with aim to improve quality and consideration the introduction these ampelographic measures in regular grapevine growing. included two treatments berry thinning (thinning bunch tip - BtT first lateral wink -BtW), girdling (G) control (C). Combined effect were n...

1 Abstract Interaction of external monochromatic, linearly polorized plane EM-wave with nonlinear one-dimensional wake wave, generated by relativistic electron bunch moving in cold plasma, is considered. At definite conditions on parameters of plasma and bunch, nonlinear wake wave can have a pronounced spikes, where plasma electron density has its maximum value and plasma electron velocities ar...

We present a first look at the new code for selfconsistent, 2D simulations of beam dynamics affected by the coherent synchrotron radiation. The code is of the particle-in-cell variety: the beam bunch is sampled by point-charge particles, which are deposited on the grid; the corresponding forces on the grid are then computed using retarded potentials according to causality, and interpolated so a...

Abstract Quantitative evaluation of the horticultural crops has high importance to identify cultivars, describe effect growing location and cultivation technology or define consumer's preference regarding size shape. Fruit traits grapevine ( Vitis vinifera L.) are mainly described by bunch berry morphology notably size, weight Ampelographers particularly evaluate based on seed number as it infl...

The parasitoid Prorops nasutaWaterston (Hymenoptera: Bethylidae) is a wasp of the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae). In this study, the attractiveness of different volatiles to P. nasuta was studied in the laboratory using a Y-tube olfactometer. Female wasps were attracted to coffee berry borer-infested coffee berries but not to uninfested or artiÞcia...

The main result of Xiao et al. [ Phys. Rev. Lett. 95, 137204 (2005)] is shown to follow from Hamiltonian mechanics. In a recent paper on the semiclassical dynamics of a Bloch electron, Xiao, Shi and Niu [1] claim that, due to a Berry curvature term, Liouville’s theorem on the conservation of the phasespace volume element would be violated, a fact which would have been overlooked so far. Their m...

Liouville's theorem on the conservation of phase-space volume is violated by Berry phase in the semiclassical dynamics of Bloch electrons. This leads to a modification of the phase-space density of states, whose significance is discussed in a number of examples: field modification of the Fermi-sea volume, connection to the anomalous Hall effect, and a general formula for orbital magnetization. ...
