A monoclonal antibody-based immunodot test was compared to a polymerase chain reaction (PCR) assay for managing white spot syndrome virus (WSSV) on shrimp farms at Kundapur and Kumta situated in Udupi and Uttar Kannada Districts, respectively, of Karnataka on the west coast of India. Of 12 grow-out farms in Kundapur, 6 (F1 to F6) yielded shrimp samples that were negative for WSSV by both immuno...

In this paper, we present an approach to construct an optical character recognition (OCR) system for recognizing rotated printed Chinese characters. Our system includes preprocessing, feature extraction, candidates selection, and target character recognition. The proposed system has a three-stage structure designed mainly to reduce the time complexity in the recognition process. Our goal is to ...

To asses the role of virus load in the pathogenesis of hemorrhagic fever with renal syndrome, the serum Dobrava virus RNA load in 46 patients was measured with a novel quantitative real-time reverse-transcriptase polymerase chain reaction assay and compared to the disease severity. The level of viremia, detected in 26 patients, ranged from 10(2)-10(8) copies/mL of serum. The patients with sever...

A key feature of the Swedish economy over last decade and a half has been the rapid internationalisation of its economy, both through FDI and trade. In this paper we consider the relationship between these two trends: whether the effect of increased inward FDI on exports by domestic firms may be positive or negative. The first case may occur as a result of demonstration effects. The second may ...

This paper compares emission taxes with other taxes from the viewpoint of emission reduction in an open economy. Using a simple monopoly model, we show that emission taxes may not be very effective to protect environment because of the spillover effects between markets stemming from non-constant marginal costs and transboundary externalities. Other taxes such as production taxes and tariffs are...
