The aim of this paper is to map agricultural crops by classifying satellite image time series. Domain experts in agriculture work with crop type labels that are organised a hierarchical tree structure, where coarse classes (like orchards) subdivided into finer ones apples, pears, vines, etc.). We develop classification method exploits expert knowledge and significantly improves the mapping rare...

Blood Vascular System, Endothelial Cells, Lymphatics, Bony Fishes Blood distribution in the systemic circulation of bony fishes is effected by a dualistic construction of the vascula­ ture: A secondary arterial system originates from the well known (primary) arteries by multiple root-like shunt vessels. These secondary arteries and the vessels they supply should no longer be regarded as lymphat...

HAEMORRHAGE from any site, and the commonest is the gut, may provoke two profound disturbances of the retina. The best recognized is blindness which begins suddenly, and is associated with subsequent swelling of the disc and often with optic atrophy. A less known but common sequel is a neuroretinopathy, first described by Ulrich (1887) and closely resembling ophthalmoscopically the neuroretinop...

In this paper a study is accomplished on behavior in a mercury electrode, of the phytohormone abscisic acid and of the conditions of accumulation in a HMDE. A mechanism is proposed of reduction based on its electrochemical behavior and proving the product of the reduction through mass spectrometry of bulks. A method is proposed for the determination of Abscisic acid (ABA) with a quantification ...

Cydia pomonella granulovirus (CpGV) based biocontrol agents are highly effective and environmentally benign control measures for codling moth (CM). In recent years, CpGV has become a corner stone for CM control both in the organic and integrated production of apple and pears. In 2005, first reports on CM populations with a dramatically decreased susceptibility to CpGV products were published. S...
