As part of its food security policy, South Korea has been pursuing food selfsufficiency using high tariffs and high administrative prices in key agricultural and food markets. Using a dual approach to trade and trade restrictiveness indices, we analyze the impact of these market distortions on welfare and trade volume. Then, we compute optimum distortions, which minimize the welfare costs of ob...
This paper investigates the relationship between spillover effects and stock market regulations for a sample of cross-listed European firms. Using LaPorta et al.’s (1998) stock exchange regulatory classification we identify firms that have cross-listed on foreign exchanges with either tougher, weaker or similar accounting disclosure, bankruptcy and shareholder protection rules. We then use the ...
The present study demonstrates tissue-specific (hemolymph and fat body) and inter-voltine [bivoltine (BV) and trivoltine (TV)] differences in oxidatively damaged products, H2O2 content, and the relative level of antioxidant protection in the diapausing pupae of Antheraea mylitta. Results suggest that fat body (FB) of both the voltine groups has oxidative predominance, as evident from the high v...
In this paper, a novel multipurpose audio watermarking algorithm is proposed based on Vector Quantization (VQ) in Discrete Cosine Transform (DCT) domain using the codeword labeling and index-bit constrained method. By using this algorithm, it can fulfill the requirements of both the copyright protection and content integrity authentication at the same time for the multimedia artworks. The robus...
The effects of Carica papaya leaf (CPL) aqueous extract on alcohol induced acute gastric damage and the immediate blood oxidative stress level were studied in rats. The results showed that gastric ulcer index was significantly reduced in rats pretreated with CPL extract as compared with alcohol treated controls. The in vitro studies using 2,2-Diphenyl-1-Picryl-Hydrazyl (DPPH) assay showed stron...
Placement of protection devices in a conventional feeder (without distributed generation) is often performed so as to minimize traditional reliability indices (SAIDI, SAIFI, MAIFIe...), assuming the sole source(s) of energy at substation(s). Distributed generation (DG) and storage units located on the feeder may be constrained in terms of power and/or energy capacity, and may include renewable ...
Procarbazine produces long-term sterility in the male by killing stem spermatogonia. The degree and selectivity of protection of stem spermatogonia in rats from procarbazine by pretreatment with steroid hormones were investigated. Male LBNF1 rats were treated for 6 weeks with Silastic implants containing testosterone plus 17 beta-estradiol. The hormone-treated rats and sham-treated controls wer...
Scientists have been long investigating procedures, models and tools for the risk analysis in several domains, from economics to computer networks. This paper presents a quantitative method and a tool for the security risk assessment and management specifically tailored to the context of railway transportation systems, which are exposed to threats ranging from vandalism to terrorism. The method...
In this contribution we present an improved indexbased a-posteriori probability (APP) decoding approach for variable-length encoded packetized data, where implicit residual source correlation is exploited for error protection. The proposed algorithm is based on a novel generalized two-dimensional state representation which leads to a three-dimensional trellis with unique state transitions. APP ...
background: breast milk is important for the overall well-being of infants. although lactation is relatively robust in the face of poor nutrition, the implication of poor nutrition on non-nutritive factors in breast milk is inconclusive. objective: this study was designed to find associations between nutritional and immune factors in maternal blood and breast milk with the aim to improve the ne...
