A comparison of fitness between horses with different exercise history AgEcon
Barker, Anna B.E.; Warren-Smith, A.K..
Anecdotal evidence suggests that a horse’s prior fitness level has an effect on the horse’s ability to return to that previous level of fitness. This trial aimed to test this assumption which would benefit horse trainers to create individual fitness programs for horses. Standardised exercise testing was used to compare the progress of two groups of horses during weeks three and seven of a 14-week training program. Group A had undergone a similar training program twelve months previously and Group B had not. Plasma lactate samples and heart rate monitoring were used to assess the levels of fitness of the horses. Analysis of variance showed that there was no significant difference in post-exercise plasma lactate concentration between the groups. The horses...

A comparison of growth and biochemical composition of Mytilus galloprovincialis (Lmk.) and Mytilus edulis (L.) on the West coast of Cotentin, Normandy, France 1999-2000 ArchiMer
Kopp, Joel; Cornette, Florence; Simonne, Charlotte.
The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from...

A Comparison of Risk and Return Characteristics of Efficient Crop Portfolios for the Brown Soil Zones Saskatchewan and Mecklenburg, Germany AgEcon
Schoney, Richard A.; Moeller, Christof.
Two efficient farms are constructed for the brown soils of Saskatchewan, Canada and for Mecklenburg, Germany based on producer panels. Both farms feature highly integrated cropping systems which take advantage of cropping synergies. However, farm risk is inherently different between the two because differences in 1) climate that gives rise to very different yield risk and cost structure, and 2) EU programs which offer fixed cash payments and stable sugar beet prices. As expected, risk is much higher for the Saskatchewan case farm - it has a chance of a negative cash flow of approximately one year in five. In sharp contrast, the Mecklenburg has very little chance of generating a negative cash flow. Hence, it is easy to understand why crop insurance and...

A comparison of soil properties under organic and conventional farming in Australia Organic Eprints
Nachimuthu, Gunasekhar; Kristiansen, Paul; Lockwood, Peter; Guppy, Chris.
Organic farming is an alternative to conventional farming for providing sustainable crops with high export demand. This review analyses research findings on organic farming in Australia, with an emphasis on soil health. Several reports have indicated that organic farm management generally improves soil physical properties in Australia and elsewhere. Although low nitrogen (N) availability can constrain yields, organic farmers can improve N supply through legume green manures. Plant available phosphorus (P) is a more serious limiting factor in organic farming, particularly in Australia with naturally low P levels. Phosphorus is less easily replaced in the soil than N, and there is a need for alternate sources of organic-certified P and methods to enhance P...

A Comparison of X, Y, and Boomer Generation Wine Consumers in California AgEcon
Wolf, Marianne McGarry; Carpenter, Scott; Qenani-Petrela, Eivis.
This research shows that the wine market in the California is segmented by age. The wine-consumption behavior of the California wine consumer differs between the Generation X consumer and those in Generation Y and Baby Boomers. There are differences in demographics, purchasing attitudes, and purchasing behaviors among wine consumers from different generations. The findings from this research demonstrate that it is increasingly important to develop marketing strategies that are segmented for the target wine consumer. Generation Y are young wine consumers who are especially important for the industry because they offer an opportunity for growth–these younger generations are developing tastes now that are likely to last as they age.

A COMPARISON ON FARMERS’ PARTICIPATION IN FARMERS’ ORGANIZATIONS AND IMPLICATIONS FOR RURAL EXTENSION IN MINAS GERAIS AgEcon
Boas, Ana Alice Vilas; Goldey, Patricia.
This paper describes a comparison on farmers’ participation in farmers’ organisations and attempts to explain why they prefer to carry out production and marketing activities by themselves. It also examines the implications of the findings for rural extension and related services. A total of 122 interviews were conducted with different categories of farmers and with the extension workers. The comparative analysis of two case studies (Cruz Alta and Pantano) showed that socio-economic characteristics were not very significant in determining the level of farmers’ participation in farmers’ organizations in Minas Gerais. The ability of managers emerged as one of the most important factors in the success or failure of farmers’ organizations. The presence of...

A complementary method for production of tetraploid Crassostrea gigas using crosses between diploids and tetraploids with cytochalasin B treatments ArchiMer
Mccombie, Helen; Ledu, Christophe; Phelipot, Pascal; Lapegue, Sylvie; Boudry, Pierre; Gerard, Andre.
We present a new method to produce tetraploid Crassostrea gigas by cytochalasin B inhibition of polar body 2 expulsion in diploid females crossed with tetraploid males. This offers a means of direct introgression of genetic characters from selected diploid to tetraploid lines, avoiding a triploid step. Offspring larval ploidy shifted over time and depended on size, with tetraploids more frequent among the smaller larvae and triploids among the large. Viable tetraploids were found at 4 and 6 months, indicating the technique was successful. The possibility that gynogenesis occurred was tested by microsatellite analysis to confirm the presence of paternally inherited alleles. These were present in all animals of the 2n x 4n + CB (female first) cross. However,...

A Computable General Equilibrium (CGE) Analysis of the Impact of an Oil Price Increase in South Africa AgEcon
McDonald, Scott; van Schoor, Melt.
Following recent international oil price increases, there has been considerable interest in how this external factor can affect the South African economy. This paper reports results from a computable general equilibrium (CGE) analysis of an increase (up to 30 per cent) in international oil prices. Background information is provided, which puts the magnitude of the price variations in historical context. We describe the procedure used to adjust the social accounting matrix (SAM), which is used to calibrate the model, to account explicitly for crude oil. Then, the effects of the crude oil price increase are traced through the economy, from markets, industries through to factors, households and the government. Predictably, the shock hurts the economy: a 20...

A computational fluid dynamics study of hydrogen bubbles in an electrochemical reactor BABT
Cavalcanti,Renata da Silva; Farias Neto,Severino Rodrigues de; Vilar,Eudésio Oliveira.
Most electrochemical reactors present reactions with the growth and departure of gas bubbles which influence on the reactor hydrodynamics and this study is usually complex, representing a vast field for research. The present paper had as objective to study a bi-phase (gas-liquid) system aiming to foresee the influence of departure of hydrogen bubbles generated on effective electrode surface situated on cathodic semi-cell. Nevertheless, it was idealized that the gas was injected into the semi cell, through the effective electrode surface With this hypothesis, it was possible to study, and numerically analyze, the hydrodynamic behavior of the hydrogen bubbles in the interior of the study domain, applying concepts of computational fluid dynamics by using the...

A conceptual and practical overview of cDNA microarray technology: implications for basic and clinical sciences BJMBR
Mello-Coelho,V. de; Hess,K.L..
cDNA microarray is an innovative technology that facilitates the analysis of the expression of thousands of genes simultaneously. The utilization of this methodology, which is rapidly evolving, requires a combination of expertise from the biological, mathematical and statistical sciences. In this review, we attempt to provide an overview of the principles of cDNA microarray technology, the practical concerns of the analytical processing of the data obtained, the correlation of this methodology with other data analysis methods such as immunohistochemistry in tissue microarrays, and the cDNA microarray application in distinct areas of the basic and clinical sciences.

A connection between extracellular matrix and hormonal signals during the development of the human fetal adrenal gland BJMBR
Chamoux,E.; Otis,M.; Gallo-Payet,N..
The human adrenal cortex, involved in adaptive responses to stress, body homeostasis and secondary sexual characters, emerges from a tightly regulated development of a zone-specific secretion pattern during fetal life. Its development during fetal life is critical for the well being of pregnancy, the initiation of delivery, and even for an adequate adaptation to extra-uterine life. As early as from the sixth week of pregnancy, the fetal adrenal gland is characterized by a highly proliferative zone at the periphery, a concentric migration accompanied by cell differentiation (cortisol secretion) and apoptosis in the central androgen-secreting fetal zone. After birth, a strong reorganization occurs in the adrenal gland so that it better fulfills the newborn's...

A Consistent Picture of Applied Protection Across the World AgEcon
Bouet, Antoine; Decreux, Yvan; Fontagne, Lionel; Jean, Sebastien; Laborde, David.
In order to provide with a consistent assessment of protection across the world in 2001, the MAcMap-HS6 database includes ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six-digit level of the Harmonized System (5,111 products), and accounting for all preferential agreements. We first describe the methodology used to compute and aggregate ad valorem-equivalent applied tariff duties, well suited for analytical purposes. Special emphasis is put in minimizing the endogeneity bias in the aggregation procedure, and in acknowledging structural differences in export specialization. We then overview applied protection across the world, in terms of average as well as distribution. Protection...

A CONSTRUÇÃO DE NOVAS ATRIBUIÇÕES PARA A ASSISTÊNCIA TÉCNICA E EXTENSÃO RURAL: A MEDIAÇÃO COM RECONHECIMENTO DA IDENTIDADE ExtensaoRural
Kreutz, Ivar José; Pinheiro, Sergio Leite Guimarães; Cazella, Ademir Antonio.
As mudanças que começaram a se delinear na década de oitenta e se consolidaram no Brasil nos anos noventa, provocando alterações institucionais profundas, assimiladas mais rapidamente pelo setor privado. As instituições públicas têm levado mais tempo para se adaptar às mudanças, mais ainda, quando possuidoras de um passado reconhecido. As instituições de extensão rural oficial representam um destes segmentos, pois suas ações foram efetivas durante a implantação do  modelo da modernização tecnológica especializada e produtivista. No entanto, o contexto está em transformação e requer novos atributos das instituições. O artigo discute as diferentes fases vividas pela extensão rural oficial, principalmente do RS, relacionado-as com os processos...
