Finishing Effect on Fatty Acid Profile of Intramuscular Fat in Extensively Reared Steers

Both the amount and the composition of fat depots in beef may be influenced by several factors i.e. feeding system. Related to this factor, extensively reared cattle may produce beef with a more desirable fatty acid (FA) composition in terms of beneficial effect on human health, especially in relation to the content of n-3 type FAs. However, concentrate finishing improves some carcass traits and meat quality. In this sense, the objective of this work was to study the effect of concentrate finishing on intramuscular (IM) FA profile of Longissimus thoracis (LT) muscle in pasture fed steers

Susceptibility of Sphenarium purpurascens purpurascens (Orthoptera: Pyrgomorphidae) instars to a commercial strain of Metarhizium acridum (Hypocreales: Clavicipitaceae) in Michoacan, Mexico.

The objective of this study was to evaluate the performance of a commercial strain of the entomopathogenic fungi Metarhizium acridum, on the different instars of the grasshopper pest Sphenarium purpurascens purpurascens, as well as its sporulation via bioassays under laboratory conditions, in Michoacan, Mexico. The most susceptible instars were nymphs one, two and four, with an average survival time of less than 6.91 days. The least susceptible was the adult, with a survival time of 8.36 days. The instars with the highest post mortem sporulation were nymphs one, two and three. A moderate negative association was registered between S. p. purpurascens and the sporulation of M. acridum, in advanced instars (nymph 4 and adult), in which sporulation was lower compared to early instars. All instars showed survival rates below 5 %, so M. acridum can be considered to be a viable option for controlling this pest in the field

The spatial distribution of multidimensional poverty in Uganda in 2014. Small area estimates of multidimensional poverty in Uganda using the 2014 Census

This report presents the first estimates of Consensual Approach multidimensional adult and child poverty in Uganda, using adult and child-specific measures of multidimensional poverty. It shows that adult and child poverty in Uganda have a clear geographical distribution and concentration, with high multidimensional poverty rates in the north. However, the subcounty-level poverty estimates also suggest that poverty is very high in the north east, the south west and some areas in the north west. Moreover, although adults and children in Kampala experience lower rates, the distribution of poverty within Kampala is not homogeneous, and there are parishes with child poverty rates of up to three times higher than the average. Finally, we show that many of these small area spatial patterns match the distribution of public services, such as distance to public health facilities and primary schools. ho This report showcases best practice from the literature while keeping to a minimum technical language. It aims to be a comprehensive and accessible analysis of the spatial patterning and concentration of multidimensional poverty in Uganda and also provide a user-friendly and step-by-step framework for future SAE analyses in Uganda

El déficit de la línea legal en el PRT-ERP : Algunas tensiones para pensar las resoluciones frente al GAN y la apertura política

Este trabajo, presentado como un avance preliminar de investigación sobre un tema puntual, no tiene mayor pretensión que presentar algunas líneas analíticas sobre un desarrollo más amplio: las tensiones al interior del PRT-ERP en cuanto a sus formas de actuación y resolución de los interrogantes (aquí entendemos que los hay permanentemente) en el contexto que se abre desde el llamado al Gran Acuerdo Nacional (GAN) y las elecciones de 1973. Este avance, tiene por objeto poder pensar y empezar a configurar algunas futuras líneas de trabajo. Tomaremos algunos documentos de la organización que refieran a la coyuntura mencionada (Boletines Internos, reuniones de Comité Ejecutivo, revista El Combatiente, etc.) donde puedan apreciarse las tensiones entre las formas y las posibilidades de acción, así como también sobre las posteriores evaluaciones de las mismas, en el transcurso de esos años.Facultad de Humanidades y Ciencias de la Educació

Chalcopyrite Leaching Kinetics in the Presence of Methanol

The dissolution of chalcopyrite under near ambient conditions represents one of the main challenges in the copper industry. Thus, various routes have been proposed for chalcopyrite treatment, such as the use of polar organic solvents, and this has shown promising results. In this paper, we present a study of copper leaching from a chalcopyrite concentrate in aqueous acidic medium with methanol and various H2O2 concentrations at 15, 30, and 40 °C. The results show that nearly complete copper extraction was attained within 5 h at 40 °C. The extraction percentages were plotted as functions of time at each temperature. The experimental data were modeled using the shrinking core model considering the cylindrical particle shape (shrinking cylinder model) within acceptable confidence levels, yielding an estimated activation energy of 24.3 kJ/mol. Furthermore, the process was dependent on the H2O2 concentration, and it acts as a reagent rather than an oxidant in the leaching reaction. It was found that sulfur is the only species present in the solid phase formed during the leaching of chalcopyrite, demonstrating the co-dissolution of both copper and iron

Vaccination programs, parity, and calving season as factors affecting the risk of fetal losses and mummified fetuses in Holstein cows

Aim of the study: To investigate vaccination programs, parity, and calving season as factors affecting the risk of abortion and mummified fetuses in Holstein cows.Area of study: Hot zone of Northeast Mexico.Material and methods: Multiple logistic regression models were used to examine the relationship between peripartum disorders, parity, previous occurrence of abortion, season of calving, vaccination program, incidence of abortion, and mummified fetuses in Holstein cows.Main results: For 7014 pregnancies (2886 cows), the percentage of cows aborting and having mummified fetuses was 17.7% and 1.1%, respectively. As the number of brucellosis vaccinations increased, the incidence of abortion increased (10.4% for a single vaccination and 38.0% for 6 accumulated vaccinations). Abortion for cows having 1-2 previous abortions (56%) and >2 abortions (77%) was fivefold and sevenfold greater (p<0.01), respectively, than that for cows without previous abortion. Other important risk factors for abortion were number of calvings (19.8% for nulliparous and primiparous vs. 13.8% for >3 parturitions; OR=1.7, p<0.01), leptospirosis vaccine application <55 days postpartum (dpp; OR=1.3, p<0.05), viral vaccine application >37 dpp (OR=1.3, p<0.01), brucellosis vaccine application >20 dpp (OR=1.6, p<0.01), and no application of clostridial vaccine (OR=3.7, p<0.01). Significant risk factors for mummified fetuses were application of ≥3 brucellosis vaccinations (OR=3.3, p<0.01), no application of 10-way clostridial vaccine (OR=2.3, p<0.01), >2 previous abortions (OR=18.4, p<0.01), and calving in autumn (OR=0.4, compared to winter, p<0.05).Research highlights: Risk of abortion and mummified fetuses in Holstein cows has been found to be related to vaccination programs
