A 2-year-old East Friesian sheep imported from Australia exhibited severe anemia after contagious pustular dermatitis in Hokkaido, Japan. Hemoplasma infection was confirmed in blood smears. Both Mycoplasma ovis and ‘Candidatus Mycoplasma haemovis’ were detected by PCR and sequence analyses. In the epidemiological analysis, dual pathogens were detected in 6 of 12 (50.0%) sheep imported from Australia with the infected ewe at the same time, 1 of 5 (20.0%) sheep introduced from a domestic farm in Hokkaido, and in 1 of 16 (6.3%) sheep from an epidemiologically unrelated ranch. It is the first clinical case of sheep to confirm coinfection of these pathogens in Japan.

A combined enrichment/polymerase chain reaction based method for the routine screening of Streptococcus agalactiae in pregnant women BJM
Munari,F.M.; De-Paris,F.; Salton,G.D.; Lora,P.S; Giovanella,P; Machado,A.B.M.P; Laybauer,L.S.; Oliveira,K.R.P.; Ferri,C; Silveira,J.L.S.; Laurino,C.C.F.C; Xavier,R.M.; Barth,A.L; Echeverrigaray,S; Laurino,J.P..
Group B Streptococcus (GBS) is the most common cause of life-threatening infection in neonates. Guidelines from CDC recommend universal screening of pregnant women for rectovaginal GBS colonization. The objective of this study was to compare the performance of a combined enrichment/PCR based method targeting the atr gene in relation to culture using enrichment with selective broth medium (standard method) to identify the presence of GBS in pregnant women. Rectovaginal GBS samples from women at ≥36 weeks of pregnancy were obtained with a swab and analyzed by the two methods. A total of 89 samples were evaluated. The prevalence of positive results for GBS detection was considerable higher when assessed by the combined enrichment/PCR method than with the...

A comparative analysis of ALOS PALSAR L-band and RADARSAT-2 C-band data for land-cover classification in a tropical moist region. Repositório Alice
LI, G.; LU, D.; DUTRA, L.; BATISTELLA, M..
This paper explores the use of ALOS (Advanced Land Observing Satellite) PALSARL-band (Phased Array type L-band Synthetic Aperture Radar) and RADARSAT-2 C-band data for land-cover classification in a tropical moist region. Transformed divergence was used to identify potential textural images which were calculated with the gray-level co-occurrence matrix method. The standard deviation of selected textural images and correlation coefficients between them were then used to determine the best combination of texture images for land-cover classification. Classification results based on different scenarios with maximum likelihood classifier were compared. Based on the identified best scenarios, different classification algorithms ? maximum likelihood classifier,...

A comparative expression analysis of gene transcripts in brain tissue of non-transgenic and GH-transgenic zebrafish (Danio rerio) using a DDRT-PCR approach Anais da ABC (AABC)
Alves-Costa,Fernanda A.; Figueiredo,Márcio A.; Lanes,Carlos F.C.; Almeida,Daniela V.; Marins,Luis F.; Wasko,Adriane P..
The presence of higher level of exogenous growth hormone (GH) in transgenic animals could lead to several physiological alterations. A GH transgenic zebrafish (Danio rerio) line was compared to nontransgenic (NT) samples of the species through a DDRT-PCR approach, with the goal of identifying candidate differentially expressed transcripts in brain tissues that could be involved in GH overexpression. Densitometric analyses of two selected amplification products, p300 and ADCY2, pointed to a significant lower gene expression in the transgenic zebrafish (104.02 ± 57.71; 224.10 ± 91.73) when compared to NT samples (249.75 ± 30.08; 342.95 ± 65.19). The present data indicate that p300 and ADCY2 are involved in a regulation system for GH when high circulating...

A comparative structural cytogenetic study in three allopatric populations of Astyanax scabripinnis (Teleostei: Characidae) Rev. Bras. Zool.
Santos,Natália M.; Ferreira-Neto,Maressa; Artoni,Roberto F.; Vicari,Marcelo R.; Bakkali,Mohammed; Oliveira,Claudio de; Foresti,Fausto.
Individual samples from five populations of the characid fish Astyanax scabripinnis (Jenyns, 1842) from the Tietê and Paranapanema river basins (Brazil) were studied. All individuals analyzed presented 50 chromosomes but three different karyotypic forms were observed. Additionally, some individuals of one karyomorph presented a macro supernumerary chromosome. No chromosomal differentiation was observed between males and females in any sample analyzed. C-banding revealed two distinct distribution patterns in these populations in which strong terminally located heterochromatic blocks were detected in the long arms of some chromosomes of the specimens from Cascatinha, Cintra, and Funari streams, whereas populations of the Capão Bonito stream and the Barbosa...

A comparison for a multiscale study of structural lineaments in southern Brazil: LANDSAT-7 ETM+ and shaded relief images from SRTM3-DEM Anais da ABC (AABC)
Jacques,Patricia D.; Machado,Romulo; Nummer,Alexis R..
This paper presents a comparison of descriptive statistics obtained for brittle structural lineaments extracted manually from LANDSAT images and shaded relief images from SRTM 3 DEM at 1:100, 000 and 1:500, 000 scales. The selected area is located in the southern of Brazil and comprises Precambrian rocks and stratigraphic units of the Paraná Basin. The application of this methodology shows that the visual interpretation depends on the kind of remote sensing image. The resulting descriptive statistics obtained for lineaments extracted from the images do not follow the same pattern according to the scale adopted. The main direction obtained for Proterozoic rocks using both image types at a 1:500, 000 scale are close to NS±10, whereas at a 1:100, 000 scale...

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products AgEcon
Hudson, Darren; Gallardo, Rosa Karina; Hanson, Terrill R..
In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

A Comparison of Consumer Willingness to Pay for Four Types of Sweeteners AgEcon
Deng, Xueting; Saghaian, Sayed H.; Woods, Timothy A..
As the U.S. consumption of sweeteners has increased, analysis of the demand for sweeteners has become more important. In this paper, consumer willingness-to-pay (WTP) for selected four types of sweeteners is evaluated. The four types of sweeteners are Kentucky grown pure maple syrup, artificially maple flavored syrup, sorghum syrup and molasses. Results suggest that consumers who are at high household income level (above $80,000) and with a smaller household size are likely to pay more for Kentucky grown maple syrup. Results show that there is no statistic difference for the annual household consumption among the four types of sweeteners.

A comparison of hypothetical survey rankings with consumer shopping behavior and product knowledge AgEcon
Grebitus, Carola; Colson, Gregory; Menapace, Luisa.
Hypothetical surveys are commonly used to elicit consumer behavior to guide product development, marketing, and labeling strategies. However, despite the prevalence of surveys in consumer food studies, previous work has not assessed the relationship between hypothetical responses and actual consumer behavior in real-world purchase situations.We explore whether attributes cited by consumers in surveys as being important to them when making decisions indeed factor into their product decision process in real-world markets. Evidence from a point of sale study of 702 pork purchasers indicates that there is a strong correspondence between hypothetical survey ratings and actual shopping behavior.

A comparison of metrics for estimating phylogenetic signal under alternative evolutionary models Genet. Mol. Biol.
Diniz-Filho,José Alexandre F.; Santos,Thiago; Rangel,Thiago Fernando; Bini,Luis Mauricio.
Several metrics have been developed for estimating phylogenetic signal in comparative data. These may be important both in guiding future studies on correlated evolution and for inferring broad-scale evolutionary and ecological processes (e.g., phylogenetic niche conservatism). Notwithstanding, the validity of some of these metrics is under debate, especially after the development of more sophisticated model-based approaches that estimate departure from particular evolutionary models (i.e., Brownian motion). Here, two of these model-based metrics (Blomberg's K-statistics and Pagel's λ) are compared with three statistical approaches [Moran's I autocorrelation coefficient, coefficients of determination from the autoregressive method (ARM), and phylogenetic...

A COMPARISON OF ORGANIC AND CHEMICAL FERTILIZERS FOR TOMATO PRODUCTION Organic Eprints
Kochakinezhad, Hamed; Peyvast, Gholam-Ali; Kashi, Abdol-Karim; Olfati, Jamal-Ali; Asadi, A..
Tomato (Lycopersicon esculentum Mill.) is one of the most popular and versatile vegetables in the world, and organic production with a high yield and desirable quality is a target of many producers. The effect of four different fertilizers (chemical, municipal solid waste compost, cattle manure, and spent mushroom compost) on four commercial tomato cultivars (Redstone, Flat, Peto Pride and Chief) was assessed in this research. The highest yield was obtained with the Chief cultivar when fertilized with chemical fertilizer and the lowest value was obtained with Peto Pride fertilized with 20 tonnes per hectare (t/ha) of cow manure. The difference between the two classes of fertilizers (organic and chemical) was not very high so that organic fertilizers are...

Small farmers have played an important role in maintaining genetic resources of traditional varieties. Collecting and characterizing germplasm, especially landraces and heirloom varieties, are strategic activities that would create a knowledge base describing the traditional varieties of a given region and reduce the risk of genetic erosion. The objectives of this work were as follows: collect sweet potato roots from rural properties and local markets in Rio de Janeiro State, Brazil; characterize the accessions using RAPD and ISSR molecular markers, comparing the efficiency in discrimination of these two types of molecular markers; and estimate the genetic variability of the population. Fifty-nine samples from rural properties and 19 from local markets...

A Comparison of Traditional and Copula based VaR with Agricultural portfolio AgEcon
Mandal, Maitreyi; Lagerkvist, Carl Johan.
Mean-Variance theory of portfolio construction is still regarded as the main building block of modern portfolio theory. However, many authors have suggested that the mean-variance criterion, conceived by Markowitz (1952), is not optimal for asset allocation, because the investor expected utility function is better proxied by a function that uses higher moments and because returns are distributed in a non-Normal way, being asymmetric and/or leptokurtic, so the mean-variance criterion cannot correctly proxy the expected utility with non-Normal returns. Copulas are a very useful tool to deal with non standard multivariate distribution. Value at Risk (VaR) and Conditional Value at Risk (CVaR) have emerged as a golden measure of risk in recent times. Though...

A competitividade do regadio de Alqueva em Portugal: o caso do bloco de rega do Monte Novo Rev. Econ. Sociol. Rural
Santos,Maria José Palma Lampreia dos; Fragoso,Rui Manuel de Sousa; Henriques,Pedro Damião de Sousa; Carvalho,Maria Leonor da Silva.
O objectivo deste estudo é avaliar a competitividade do regadio de Alqueva no Sul de Portugal na região Alentejo. O estudo foi realizado com base em três grupos de explorações agrícolas representativas seleccionadas de uma amostra de explorações agrícolas do bloco de rega do Monte Novo. Para cada uma delas, foi desenvolvido um modelo de programação matemática multi-período adaptado às suas características específicas. Os principais resultados permitem concluir que a Política Agrícola Comum e a Directiva Quadro da Água condicionam a competitividade do regadio nesta região. No entanto, a adopção de novas tecnologias de produção permitirá contrariar esses efeitos negativos e assegurar a competitividade futura do regadio.
