PRINCIPAIS ASPECTOS RELACIONADOS À NUTRIÇÃO DE CÃES E GATOS Sci. Agrar.Paran. / SAP
A. P. Félix; UFPR; S. G. Oliveira; UFPR; A. Maiorka; UFPR.
Cães e gatos são animais carnívoros e, portanto, apresentam alta necessidade de proteínas e lipídios na dieta. As altas necessidades proteicas e lipídicas são particularmente inerentes aos gatos, uma vez que estes apresentam fisiologia orientada para metabolizar aminoácidos, ácidos graxos e glicerol da dieta. Já, cães podem ser considerados animais nutricionalmente oportunistas, uma vez que apresentam maior adaptabilidade fisiológica para aproveitar os diferentes macronutrientes presentes nos alimentos, inclusive os carboidratos. Em virtude do alto grau de domesticação desses animais, cada vez mais seus...

Areas of endemism in the southern central Andes Darwiniana
Aagesen,Lone; Bena,Maria J.; Nomdedeu,Soledad; Panizza,Adela; López,Ramiro P.; Zuloaga,Fernando O..
This paper analyzes the distribution of vascular plants species endemic to the southern central Andes (south-western Bolivia and north-western Argentina). All 540 species endemic to the study regions (approx. 720600 km²) have been included in the analysis. The main part of the endemic species is found in semiarid habitats between 1500-3500 m asl pointing to the topographically complex plateau, slope, and valley system of the southern central Andes as the main locations for its endemic flora. The distribution of the endemic species within arid sites is in contrast with that of vascular plant diversity in general, as the most diverse habitat of the region is the moist subtropical Tucumano-Bolivian Yungas forest of the eastern Andes slope. A total of 17 well...

Genetic diversity analysis of isolates of the fungal bean pathogen Pseudocercospora griseola from central and southern Brazil. Repositório Alice
ABADIO, A. K. R.; LIMA, S. S.; SANTANA, M. F.; SALOMÃO, T. M. F.; SARTORATO, A.; MIZUBUTI, E. S. G.; ARAÚJO, E. F.; QUEIROZ, M. V. de..
Planting resistant varieties is the most effective control measure against the angular leaf spot of dry beans, a fungal disease caused by Pseudocercospora griseola. However, dry bean varieties with durable resistance are not easily obtained. Knowledge about the genetic variability of the pathogen population is key for the success of dry bean breeding programs aimed at developing resistant materials, but finding suitable operationally simple and genetically accurate markers is not an easy task. The aim of this study was to assess the suitability of the ISSR-PCR technique to quantify the genetic variability of P. griseola isolates. Total DNA of 27 P. griseola isolates from Goiás, Minas Gerais, Espírito Santo, and Paraná States was extracted and amplified...

Analysis of farm household technical efficiency in Northern Ghana using bootstrap DEA AgEcon
Abatania, Luke N.; Hailu, Atakelty; Mugera, Amin W..
Crop production is the main source of livelihood for households in Northern Ghana. The government is committed to improving crop production and knowledge about the technical efficiency of crop farms is essential in guiding policy decisions. This paper examined the technical efficiency of 189 crop farms in Northern Ghana using data envelopment analysis (DEA) with bootstrapping. We found that bias-corrected average technical efficiency of the sample farms is 77.26%. The estimated scale efficiency is 94.21%. In a second stage regression, we found that hired labour, geographical location of farms, gender and age of head of household significantly affect technical efficiency. Policy implications of the results are discussed.

Stability analysis of forage production in Bromus catharticus (prairie grass) using three methodologies Ciencia e Investigación Agraria
Abbott,Liliana; Filippini,Susana; Delfino,Hugo; Pistorale,Susana.
Thirteen genotypes of Bromus catharticus (prairie grass) were evaluated for forage production over three years using completely randomized trials with six replicates. The genotype x environment interaction was statistically significant and indicates that the behavior of genotypes differs over time. Once this interaction was detected, we used three methodologies to assess the stability of genotypes: Wricke's ecovalence, the Lin and Binns index, and the Eberhart and Russell model. The methods of Lin and Binns and Eberhart and Russell indicate that genotypes 11, 9, 3 and 4 are stable. They also rule out possible selection of genotypes 2, 10, 1 and 12 for lack of stability or poor adaptation. The correlation among these indices was statistically significant...

Wave runup estimates at gentle beaches in the northern Indian Ocean OceanDocs
Abdalazeez, Ahmed.
The aim of this study is to estimate the wave runup on selected beaches around the northern Indian Ocean. The runup has been estimated using ERA-Interim, which is the latest global atmospheric re-analysis produced by the European Center for Medium-Range Weather Forecasts (ECMWF). ECMWF uses the global Wave Model (WAM) model to calculate two dimensional wave spectra. The distances between the model grid points and the beaches have been calculated by a great circle calculator. The beach slopes have been calculated by Google Earth for all locations, except Maldives beach, which was assumed as an imaginary beach because the method of calculating the slope could not be used there. The significant wave height as well as the peak wave period at the grid points...

Abdalla, Ishtiag; Abdalla, Sahar Babiker; El-Siddig, Kamal; Möller, Detlev; Buerkert, Andreas.
In Khartoum (Sudan) a particular factor shaping urban land use is the rapid expansion of red brick making (BM) for the construction of houses which occurs on the most fertile agricultural Gerif soils along the Nile banks. The objectives of this study were to assess the profitability of BM, to explore the income distribution among farmers and kiln owners, to measure the dry matter (DM), nitrogen (N), phosphorus (P), potassium (K) and organic carbon (C_org) in cow dung used for BM, and to estimate the greenhouse gas (GHG) emissions from burned biomass fuel (cow dung and fuel wood). About 49 kiln owners were interviewed in 2009 using a semi-structured questionnaire that allowed to record socio-economic and variable cost data for budget calculations, and...

Three new species of Monogenea (Platyhelminthes) parasites of fish in the Guandu river, southeastern Brazil - doi: 10.4025/actascibiolsci.v34i4.10466 Biological Sciences
Abdallah, Vanessa Doro; Universidade Federal Rural do Rio de Janeiro; Azevedo, Rodney Kozlowiski de; Universidade Federal Rural do Rio de Janeiro; Luque, José Luis Fernando; Universidade Federal Rural do Rio de Janeiro.
Current essay describes three new Monogenean species, namely, Cosmetocleithrum striatuli sp. nov., Jainus leporini sp. nov. and Rhabdosynochus guanduensis sp. nov., parasites on the gills of Trachelyopterus striatulus (Steindachner, 1877), Leporinus copelandii Steindachner, 1875 and Centropomus undecimalis (Bloch, 1792), respectively. Fish were collected from the Guandu river, State of Rio de Janeiro, Brazil between August 2005 and November 2008. Cosmetocleithrum striatuli sp. nov. differs from all other congeneric species by the shape of an accessory piece (more robust and resembling a crustacean claw or chela) and by the shape of its ventral and dorsal bars (not V-shaped and with expanded lateral ends directed to the rear). Jainus leporini sp. nov....

Validated microbiological and HPLC methods for the determination of moxifloxacin in pharmaceutical preparations and human plasma BJM
Abdelaziz,Ahmed A.; Elbanna,Tarek E.; Gamaleldeen,Noha M..
The article presents a comparison between microbiological and high performance liquid chromatographic (HPLC) assays for quantification of moxifloxacin in tablets, ophthalmic solutions and human plasma. The microbiological method employed a cylinder-plate agar diffusion assay using a strain of Esherichia coli ATCC 25922 as the test organism and phosphate buffer (pH8) as the diluent. The calibration curves were linear (R²&gt; 0.98) over a concentration range of 0.125 to 16 µgml-1. The within day and between days precisions were < 4.47% and < 6.39% respectively. Recovery values were between 89.4 and 110.2%. The HPLC assay used Hypersil® BDS C18 reversed phase column (250×4.6 mm, 5µm) with a mobile phase comprising 20 mM ammonium dihydrogen...

Physiological studies on carboxymethyl cellulase formation by Aspergillus terreus DSM 826 BJM
Abdel-Fatah,Osama M.; Hassan,Mohamed M.; Elshafei,Ali M.; Haroun,Bakry M.; Atta,Housam M.; Othman,Abdelmageed M..
Physiological studies were conducted to determine the optimum cultural conditions for maximal carboxymethyl cellulase (CMCase) formation by Aspergillus terreus DSM 826. Shaking condition at 150 rpm is favorable for the production of CMCase from rice straw and sugar cane bagasse. The highest enzyme yield was obtained at the third day of incubation at 30ºC for both cases; however CMCase formation occurred at a broad range of pH values, with maximal formation of A. terreus DSM 826 CMCase at pH 4.5 and 5.0 when rice straw and sugar cane bagasse were used as sole carbon source, respectively. Carboxymethyl cellulose (CMC) was found to be a good inducer for CMCase formation in both agricultural wastes with CMC concentrations of 0.5 and 1.0 % (w/v) in case of rice...

The effects of 4-nonylphenol contamination on livers of Tilapia fish (Oreochromus spilurs) in Jeddah Biol. Res.
Abdulla Bin-Dohaish,El-jawaher.
Alkylphenol polyethoxylates is a group of estrogenic compounds. Natural or synthetic types of these compounds react with the endocrine system by binding hormone receptors, resulting in interference with their action, which is why they are called endocrine disrupting chemicals. Among their hydrolytic products are nonylphenols (NP), which are considered pollutants of aquatic environments. The objective of this study was to evaluate the pathological alterations on liver tissue of fish exposed to these compounds for long durations, starting from beginning of life and during the period of sexual maturity. Tilapia fish were obtained from Abhur fish farms, reared in the laboratory in special basins, and divided into two groups. The first maternal group was...
