The nucleotide sequence of the genomic RNA1, 7342 nucleotides (nt) of grapevine fanleaf virus strain F13 (GFLV-F13) has been determined from cDNA clones. The complete sequence contained only one long open reading frame (ORF) of 6852 nucleotides extending from nucleotide 243 to 7101. The putative polyprotein encoded by this ORF is 2284 amino acids in length with an Mr of 253K. The location of ge...

We propose a model to study the role of industry-level external economies scale in open economies. If elasticity governing strength is below inverse trade each industry, then specialization under frictionless consistent with comparative advantage, tractable even frictions, and all countries gain from trade. External lower gains except if country specializes industries high economies, they ampli...

Primary familial brain calcifications (PFBC) are a heterogeneous group of rare autosomal dominant disorders. Mutations in the PDGFB gene are the second most common cause of PFBC. A model for PDGFB-associated PFBC, hypomorphic PDGFB (ret/ret) mouse, displays impaired blood-brain barrier (BBB), progressive brain calcifications and increased flux of the oxysterol 24S-hydroxycholesterol from the br...

A set of full-length cDNA clones of the satellite RNA of grapevine fanleaf nepovirus isolate F13 (GFLV-F13) was constructed with a variable number of additional, non-viral nucleotides at the 5' and 3' ends. The biological activity of the RNAs transcribed from these constructs was tested in Chenopodium quinoa protoplasts using a helper virus. When inoculated with arabis mosaic virus S (ArMV-S) R...

This paper surveys recent developments in the literature on trade facilitation, defined broadly as reform of non-tariff barriers. The paper looks at what trade facilitation is, why it matters, how to measure it, the gains from reform, and ways to implement it at the global, regional and unilateral level. JEL Classification: F13, F15.

Individuals working in commercial hog confinement facilities have elevated incidences of headaches, depression, nausea, skeletal muscle weakness, fatigue, gastrointestinal disorders, and cardiovascular diseases, and the molecular mechanisms for these nonrespiratory ailments remain incompletely undefined. A common element underlying these diverse pathophysiologies is perturbation of intracellula...

This paper assesses the long-run bilateral trade relations between the US and Mexico. North American Free Trade Agreement (NAFTA) had no additional impacts on import functions. Gradual switching existed even before the agreement became effective. © 2002 Society for Policy Modeling. Published by Elsevier Science Inc. All rights reserved. JEL classification: F13; C22

A dominant firm holding import quota engages in inter-temporal price discrimination when facing a competitive fringe engaged in seasonal production. This causes a welfare loss that comes in addition the loss attributable to limitation of imports below the free trade level. JEL classification: F12, F13

We report the discovery of a new factor for each of the Fermat numbers F13, F15, F16. These new factors have 27, 33 and 27 decimal digits respectively. Each factor was found by the elliptic curve method. After division by the new factors and previously known factors, the remaining cofactors are seen to be composite numbers with 2391, 9808 and 19694 decimal digits respectively.
