Viticulture involves significant levels of machinery traffic, causing heavy soil compaction. In particular, the compaction subsoil is increased; a deep tillage could certainly solve problem, but risk damage to plants’ root system high. The aim this study was investigate trend both top- and sub-soil in hillside vineyard located Tuscany (Italy), investigating different machine-implement combinati...

AbstractIt is critically important to intensify farming systems in sub-Saharan Africa by disseminating improved agronomic practices and increasing the application of modern inputs (Chaps. 1 2 this volume). One region’s challenges that proper land preparation difficult due scarcity draft animals underdevelopment tractor rental market (Chap. 7). Our analysis rice production Cote d’Ivoire reveals ...

Measurement of the values of forces in tractor arms is of great importance due to draft of agricultural equipment. These values can be used for testing and evaluation of the agricultural machinery, selection of suitable tractor, etc. The tools which are used for measurement of the forces are called dynamometer. The main objective of the present study was to design and evaluate a load cell for i...

Sugarcane is one of the severely perishable crops that is used as raw material for white sugar production. Sucrose content of the sugarcane which is of high commercial value decreases in quality due to pre-harvest burning, high ambient temperature, kill-to-mill delays as well as microbial contaminations. Delays in sugarcane transportation are the most important risks which can affect the qualit...

We propose a tractor atom interferometer (TAI) based on three-dimensional (3D) confinement and transport of split atomic wavefunction components in potential wells that follow programmed paths. The paths are to recombine wavefunctions at well-defined space-time points, guaranteeing closure the interferometer. Uninterrupted 3D interfering eliminates coherence loss due wavepacket dispersion. Usin...

The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people we...

This is an outline of my lecture at the Hayama Symposium on several complex variables on December 21, 2002. The subject of the talk are new applications of the canonical Cartan connection for CR manifolds. Most of the results I will report on are based on joint research (partly in progress) with A.R. Gover and with J. Slovák and V. Souček. Partly, these results are specific for the class of CR ...
