Adjustment of Conventional PSE's Methodology for Economy in Transition

Mycek, Paul; Pinon, Gregory; Germain, Gregory; Rivoalen, Elie.

The modelling of diffusive terms in particle methods is a delicate matter and several models have been proposed in the literature. The Diffusion Velocity Method (DVM) consists in rewriting these terms in an advective way, thus defining a so-called diffusion velocity. In addition to the actual velocity, it is used to compute the particles displacement. On the other hand, the well-known and commonly used Particle Strength Exchange method (PSE) uses an approximation of the Laplacian operator in order to model diffusion. This approximation is based on an exchange of particles strength. Although DVM is particularly well suited to particle methods since it preserves their Lagrangian aspect, its major drawback stems in the fact that it suffers from severe...

Agricultural Producer Support Policy in Iran and Selected Countries

Shick, Olga.

The conventional PSE's methodology doesn't provide adequate estimation of agricultural support for the economy in transition. In this paper we attempt to adjust PSE's methodology for Russian economy, and also coefficients' analysis and interpretations are adapted for transitional conditions. Investigation showed that the level of agricultural support in Russia is much lower than conventional methodology estimates.

Agricultural policies in Iran have aimed at achieving self-sufficiency in food productions through the government various policies. The aim of this paper is to examine the current level of protection which may exist in agricultural sector in Iran and other countries. The results indicate that the PSE in Iran is much higher than the OECD and is close to Japanese and Korean PSE percentage (i.e. 58 and 64 percent). The broadest indicator of support representing the sum of transfers to agricultural producers (PSE), expenditure for general services (GSSE), and direct budgetary transfers to consumers, reached 83 billion Dollars per year in 2001-2005 which is almost equivalent to 13.4 percent of Iran’s GDP in this period. This is much...

Aquaculture in New Zealand

Aspectos genético-quantitativos da qualidade da carne em frangos

Hayden, B.

Aquaculture is a relatively new activity in New Zealand. The indigenous rock oyster (Saccostrea glomerata ) was the first target for aquaculture in the 1930's although it was not intensively cultured until the 1960's. The faster growing Pacific oyster (Crassostrea gigas ) appeared in 1969/70 and now comprises virtually all the farmed oysters in New Zealand.

O estudo dos parâmetros genéticos das características de qualidade de carne de aves permite à industria avícola se adequar às exigências da indústria processadora, aumentando sua eficiência, e melhorando a aceitação da carne de frango pelo mercado consumidor. Além disso, por meio do estudo destes parâmetros, valiosas informações sobre a caracterização do fenômeno denominado PSE, que representa a carne pálida, flácida e exsudativa, podem ser obtidas, uma vez que são escassos os estudos a esse respeito em frangos. O conhecimento do comportamento genético e da relação entre os atributos da carne e outras características de interesse em frangos de corte pode favorecer o estabelecimento mais preciso e adequado das estratégias utilizadas nos programas de seleção.

ABSTRACT: Pork may be classified into quality categories according to its color, texture and exudation, though no international consensus criterion has been reached yet. Thus, the aim of the present paper was to examine the relation between important meat quality traits, evaluating pork quality classification of a same data by different criteria proposed in the literature. In 60 pork loins (Longissimus thoracis muscle), initial pH (pH45min) and R-value were evaluated after 45min post mortem between the 9th and 10th ribs, and ultimate pH (pH24h), objective color and water-holding capacity were evaluated 24h post mortem in two 2.54cm thick steaks cut between the 9th and 11th ribs to be classified into PSE (pale, soft and exudative), RSE (reddish-pink, soft...

O gene do estresse suíno (gene hal), em homozigose recessiva (nn), está associado com a ocorrência da Síndrome do Estresse Porcino (PSS) e com a ocorrência da carne pálida, mole e exudativa (PSE). Em heterozigose (Nn), está relacionado com diminuição na qualidade da carne porém, com maior peso de carcaça. Neste estudo, foi caracterizado o genótipo do gene hal de 160 suínos por meio de análise do DNA extraído de um único folículo piloso. Estes animais foram abatidos e, após, mensuradas características de carcaça de cada um. Entre os 160 animais analisados, 82 (52,58%) foram caracterizados como NN, 67 (41,80%) como Nn e nove (5,62%) como nn. A variação das características de carcaça entre os genótipos foi avaliada por análise de variância, usando o SAS. Os...

Effects of Agricultural Policy Measures on Gross Transfers to Farmers: Intertemporal and Interregional Evidence from the CAP

Bird, P; Arnold, G; Holliday, J; Boronovshy, A.

In December, 1990, the N.S.W. Minister for Agriculture and Rural Affairs removed the Pacific oyster (Crassostrea gigas) from the noxious fish list for the Port Stephens area, permitting it's cultivation. As Port Stephens Pacific oysters are grown intertidally, similar to Sydney rock oysters (Saccostrea commercialis) there was a belief that they may have different storage requirements to overseas Pacific oysters which are cultivated in deep water exclusively. Consequently, the keeping quality of this oyster and it's compliance with N.S.W. bacteriological regulations were examined. Port Stephens Pacific and Sydney rock oysters were purified, then stored at refrigeration and ambient temperatures. Levels of faecal coliforms, standard plate count and Vibrio...

Farm Income, Financial Conditions and Government Assistance - Data Book

Hansen, Heiko.

This paper analyses the effects of the Common Agricultural Policy (CAP) on gross transfers over time and across regions. Depending on the type of instrumentation to support agriculture, the volatility of gross transfers differs. While assistance arising from market price supports, regarded as independent from the world market levels, fluctuates intertemporally, direct payments are constant. Empirical findings for the CAP show a reduction of the transfer volatility on grain markets. For beef and veal this effect is not significant, because price support is still large in these markets. If agricultural support is biased in favour of specific commodities, territorial heterogeneity leads to an uneven distribution. By applying a regionalised concept of producer...

Samples of Pectoralis major m. were collected, and an RT-PCR analysis of the a-Ryanodine receptor (a RYR) from chicken mRNA hotspot region spanning aminoacid residues 386 to 540, numbered according to the turkey sequence, revealed two classes of transcripts. The sequences of the first class were similar to turkey and human with 97% and 74% of identity, respectively, and included all transcripts with substitutions in the nucleotide sequence. The second class was characterized by the deletion of nucleotides, leading to a premature stop codon and coding for a truncated and nonfunctional protein. These results are to date the first report related to the sequencing of the chicken αRYR hotspot region 1, which will possibility serve as a guide for further studies...

Qualidade da carne de suínos de três linhagens genéticas comerciais em diferentes pesos de abate

Hine, P.

Bonamia has also caused 40%-60% mortalities in two or three stocks of O. lutaria held on a mussel farm 800 km north east of Foveaux Strait. Mass winter mortalities have been reported among native rock oysters, Saccostrea glomerata , until recently the basis of oyster farming. Similar blisters occur in the shell of the currently farmed Crassostrea gigas and may be associated with ectosymbionts. Mortalities and disease have not been reported in the intensively-farmed green-lipped mussel (Perna canaliculus ) or blue mussel (Mytilus edulis aoteanus ), but digenean sporocyts are common in these species. All these bivalve species may contain the copepod, Pseudomyicola spinosus , in the gut, but pathogenicity has not been demonstrated. Pea-crabs are also common...
