Chilling temperatures (below 10' but above the freezing point of the tissue) injure fruits of coldsensitive crops native to tropical and subtropical areas (1,4, 5). Sweet orange (Citrus sinensis Osb.) fruits, even though mature internally, may not lose their chlorophyll on the trees when grown in tropical climates. However, oranges grown on the northern fringes of the sutbtropical regions of Fl...

Understanding how perceptual and conceptual representations are connected is a fundamental goal of cognitive science. Here, we focus on a broad conceptual distinction that constrains how we interact with objects--real-world size. Although there appear to be clear perceptual correlates for basic-level categories (apples look like other apples, oranges look like other oranges), the perceptual cor...

Mixed-initiative dialogs often contain interruptions in phrase structure such as repairs and backchannel responses. Phrase structure as traditionally de ned does not accommodate such phenomena, so it is not surprising that phrase structure parsers are ill-equipped to handle them. This paper presents metarules that specify how the instantiations of phrase structure rules may be restarted or inte...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were com...

Decaying oranges or other citrus fruits are almost invariably infected by one of two moulds, viz.,P. digitatum Saccardo ( = P. olivaceum W ehmer), which causes the olive-coloured rot, and P. italicum Wehmer, which is responsible for the blue-green rot. I t has been found in the course of work tha t each of these species has very definite biochemical characteristics which are described in this p...

A cellular automata model is proposed to analyze the progress of Citrus Variegated Chlorosis epidemics in São Paulo oranges plantation. In this model epidemiological and environmental features, such as motility of sharpshooter vectors which perform Lévy flights, hydric and nutritional level of plant stress and seasonal climatic effects, are included. The observed epidemics data were quantitativ...

In this course we will consider mathematical objects known as lattices. What is a lattice? It is a set of points in n-dimensional space with a periodic structure, such as the one illustrated in Figure 1. Three dimensional lattices occur naturally in crystals, as well as in stacks of oranges. Historically, lattices were investigated since the late 18th century by mathematicians such as Lagrange,...

The idea for WAFL came about through a series of conversations that Jaklin Kornfilt and I have had over the past ten years. As we looked at constructions in Japanese, Turkish, and related languages, it became apparent that an analysis of a particular construction in Japanese could be confirmed, extended, or even questioned by comparing it to Turkish, and vice versa. Of course, one can always ma...

Fruits from many citrus cultivars develop depressed areas in the flavedo (outer part of the peel) and albedo (inner part) following detachment. Although ultrastructural analysis may provide important information about multiple plant responses to stresses and external stimuli at the cell and tissue levels, and despite the proved efficacy of ethylene in reducing peel damage in citrus fruit, cytol...

The endothelial cells (ECs) make up the inner lining of blood vessels, acting as a barrier separating and tissues in several organs. ECs maintain endothelium integrity by controlling constriction relaxation vasculature, fluidity, adhesion, migration. These actions are efficiently coordinated via an intricate signaling network connecting receptors, wide range cellular macromolecules. naturally q...
