purpose: to report a case who had optic disc duplication, a rare congenital disorder characterized by two well-defined discs in one eye. case report: a 19 months-old child presented with unilateral epiphora in the right eye since birthday. the right eye was smaller than the left eye and mild ptosis was apparent. nasolacrimal duct probing was performed under general anesthesia. the examination r...

We define a “hot potato” to be an exchange good which may be traded a finite number of times, and which becomes a bad if and when it can no longer be exchanged. Under standard assumptions of rationality and common knowledge, it is easy to show that no rational actor would freely accept a hot potato good, irrespective of the magnitude of the good’s exchange payoff or its last-holder penalty. Bou...

In comparison to single infections, co-infection of Nicotiana benthamiana with Potato virus X (PVX) and Potato virus Y (PVY) or Plum pox virus (PPV), resulted in increased systemic symptoms (synergism in pathology). Previous studies have shown that virus infections affected the accumulation of various microRNAs (miRNAs) and miRNA target genes. Our studies revealed that double infection by PVX a...

An, L.V., 2004. Sweet potato leaves for growing pigs: Biomass yield, digestion and nutritive value. Doctor’s dissertation. ISSN 1401-6249, ISBN 91-576-6750-0 The aim of the present studies was to evaluate the potential of using sweet potato leaves (Ipomoea batatas (L.) Lam) as a protein source in diets for growing pigs. A number of sweet potato varieties were evaluated with respect to the bioma...

Chromosome pairing relationships within cultivated potato (Solanum tuberosum) and its wild tuber-bearing relatives (Solanum sect. Petota) have been interpreted by genome formulas, developed in the early 1900s, through techniques of classic meiotic analysis of interspecifi c hybrids. Here we reexamine potato genome hypotheses with the fi rst phylogenetic analysis of all major genomes of sect. Pe...

agricultural training centres (atcs) promote crop and livestock development by providing extension information to farmers and serving as models of improved crop and livestock husbandry practices. although potato farmers in nyandarua county were trained on potato production technologies, their average yield was ≤16 tonnes per hectare compared to the national potential of 30 tonnes. this study th...

Potato is a strategic crop in Tunisia but is susceptible to many pests and diseases. Nematodes of the genera Meloidogyne and Globodera are important pests that cause yield losses and depreciation of tuber quality. A trial was carried out in a plot where the soil was naturally infested with M. javanica and G. pallida. Three soil treatments were tested and compared. Soil solarization (SS) and inc...

In this paper we consider dynamic routing on trees under the \matching with consumption" routing model, a natural extension of the matching routing model introduced by Alon, Chung and Gra-ham 1, 2], which allows for the consumption of packets when they reach their destination. We present an asymptotically optimal on-line algorithm that routes k packets to their destination within d(k ? 1) + d d...

We study the possibility of achieving efficiency in a dynamic adverse selection market for durable goods. The idea is to use the number of times a car has been traded (“vintage”) as a signal of its quality. Higher-valuation consumers experiment with younger vintages. We first exhibit an impossibility result: no choice of (re)sale prices can induce consumers to follow this experimentation policy...

This paper introduces hot potato high level synthesis transformation techniques. These techniques add deflection operations in the behavioral description of a computation in such a way that the requirements for two important components of the final implementation cost, the number of registers and the number of interconnects, are significantly reduced. Moreover, it is shown how hot potato techni...
