Grape sour (bunch) rot is a polymicrobial disease of vineyards that causes millions of dollars in lost revenue per year due to decreased quality of grapes and resultant wine. The disease is associated with damaged berries infected with a community of acetic acid bacteria, yeasts, and filamentous fungi that results in rotting berries with high amounts of undesirable volatile acidity. Many insect...

We have studied fast ion instability (FII) in the electron ring (HER) at KEKB. We introduce an application of Singular Value Decomposition (SVD) to study multi-bunch beam oscillations. The SVD analysis[1] has been performed for a matrix consists of vertical bunch positions in a turn-byturn and bunch-by-bunch to extract wave lengths which characterized the behavior of multi-bunch beam instabilit...

Two Hadamard matrices of order 764 of Goethals– Seidel type are constructed. Recall that a Hadamard matrix of order m is a {±1}-matrix A of size m × m such that AA T = mI m , where T denotes the transpose and I m the identity matrix. We refer the reader to one of [2, 4] for the survey of known results about Hadamard matrices. In our previous note [1], written about 13 years ago, we listed 17 in...

In high charge RF photoinjectors for wakefield two beam acceleration studies, due to the strong longitudinal space charge, bunch lengthening between the photocathode and photoinjector exit is a critical issue. We present beam dynamics studies of bunch lengthening in an RF photoinjector for a high charge electron beam and describe methods to compensate the bunch lengthening to various degrees. I...

In the Serra Gaúcha region, South Brazil, occurrence of hail is common due to relief and cold air currents coming from polar regions. Nowadays, use anti-hail nets protect fruit production increasing, but real effects using this coverture on vines are largely unknown. Thus, work aimed evaluate impact an net productivity quality parameters ‘Rose Niagara’ grapes grown in 2019/2020 2020/2021 harves...

A prototype programmable bunch-by-bunch signal acquisition and processing channel with multiple applications in storage rings has been developed at SLAC. The processing channel supports up to 5120 bunches with bunch spac-ings as close as 1.9 ns. The prototype has been tested and operated in five storage rings: SPEAR-3, DA¨NE, PEP-II, KEKB, and ATF damping ring. The testing included such applica...

The use of manual (i.e., active) restraint systems (or seat belts) in cars has increased dramatically over the last several decades, changing from around 10% in the late 1970s to as much as 68% in the 1990s (Datta & Guzek, 1992; National Highway Traffic Safety Administration [NHTSA], 1996b). Several factors are responsible for this increase. One important determinant has been the passage of man...

In a mature Vitis labrusca L. ‘‘Niagara’’ vineyard, we compared an airblast sprayer and an air-assisted rotary atomizer (AARA) low-volume sprayer for coverage of grape clusters and control of grape berry moth, Paralobesia viteana. In addition, the effect of spray volume on control of fungal diseases was evaluated using the fungicides ziram and azoxystrobin applied with an airblast sprayer. For ...

The present trial follows a previous study about pre-flowering leaf removal (LR) (Verdenal et al., 2019) and validates the sustainability of mechanical LR under local Swiss vineyard conditions, using low-pressure double airflow, to reduce cost laborious bunch thinning. In studies, has shown additional benefits over post-berry-set in terms yield regulation grape wine compositions. This had two o...
