Jóvenes cordobeses: una cartografía de su emocionalidad política
Bonvillani,Andrea;
Nómadas , 2010,
Abstract: in the cartography of a political emotion that uses the metaphor of polychromy to show the shades that characterize the subjective record of politics in popular sectors youths of córdoba (argentina), in this article we describe the instrumentation of passions in subjection processes to the social order in tension with the possibilities of subjective emancipation that passions offer.
Roma y Maxi: dos biografías de militancia
Andrea Bonvillani
Utopia y Praxis Latinoamericana , 2012,
Abstract: Partiendo del interrogante por cuáles son las necesidades, expectativas y competencias que inciden en la decisión por la militancia en jóvenes, en articulación con las oportunidades de participación que ofrecen las coyunturas políticas locales, en el artículo se analiza de qué modo las disposiciones subjetivas se pueden traducir en una acción efectiva de militancia, en tanto proceso de socialización política situado en espacios y tiempos determinados. Se realizaron entrevistas biográficas con dos jóvenes de la ciudad de Córdoba (Argentina), una que participó hace algunos a os de un movimiento social y otro que lo hace actualmente en un colectivo juvenil autogestionado
Juventud y política en la Argentina (1968-2008): Hacia la construcción de un estado del arte
Bonvillani,Andrea; Palermo,Alicia Itatí; Vázquez,Melina; Vommaro,Pablo A.;
Revista argentina de sociolog?-a , 2008,
Abstract: the paper presents a state-of-the-art of argentine youth politics in the late 1960s -between 1968-1969, related to the popular mobilization known as the cordobazo- and today's youth politics. the research focuses on education and the student movement, social movements, political parties, and trade unions, as well as cultural movements, and youth aesthetics. for each historical period, the article analyzes the most significant events, actions, practices, and problems explored by the existing academic research on the subject. at this point, this state-of-the-art does not include other discourses on argentine youth (such as the media, or public policy). far from ignoring such discourses or narratives of youth, this is a methodological approach at this early stage of the research.
Muscle and genotype effects on fatty acid composition of goat kid intramuscular fat
Francisco Pe?a,Manuel Juárez,Adriana Bonvillani,Pilar Garcia
Italian Journal of Animal Science , 2011, DOI: 10.4081/ijas.2011.e40
Abstract: Little is known about the fatty acid composition of the major muscles in goats from different breeds. Forty entire male suckling kids, 20 Criollo Cordobes and 20 Anglo Nubian, were slaughtered at 75 days of age and the fatty acid composition of their longissimus thoracis (LT) and semitendinosus (ST) muscles was analysed to clarify the effects of genotype and muscle type on goat kid meat. Genotype had a great influence on the fatty acid composition of goat kid meat. Meat from Criollo Cordobes had greater saturated (P<0.001) and lower monounsaturated (P<0.001) and polyunsaturated fatty acids (P=0.002) concentration than meat from Anglo Nubian, showing higher saturated fatty acids (SFA). On the other hand, intramuscular fat content from both genotypes was higher (P=0.042) in ST muscle, while the lowest cholesterol levels were observed in ST of Criollo Cordobes (P=0.038). That higher fat content resulted in lower relative contents of total polyunsaturated (P<0.001) and n-3 (P=0.002) fatty acids due to the lower contribution of the membrane phospholipids.

Abstract: some alleles of milk protein loci are associated with superior cheese production characteristics. the genetic polymorphism of the milk protein loci as1-casein, b-casein, k-casein and b-lactoglobulin was examined in argentinian holstein cattle. samples from 12 herds of four regions of córdoba were analyzed by starch gel electrophoresis. the c2 test was used to assess whether the populations were in hardy-weinberg equilibrium. genotypic diversity was analyzed by the shannon-weaver index. the observed genotypic frequencies were analyzed by hedrick's genetic identity and the genetic distance of balakrishnan and sanghvi. the allelic and genotypic frequencies were similar to those of other holstein populations. the genotypic frequencies of the as1-casein and b-casein loci were in equilibrium, whereas in some populations the k-casein and b-lactoglobulin loci were not. according to the shannon-weaver index the total genetic diversity within each herd was greater than 96%. the high values of identity agreed with the low genetic distances among populations. we conclude that there is extensive genetic homogeneity in holstein cattle in córdoba province and that it would be feasible to select for b alleles at the k-casein and b-lactoglobulin loci in order to improve the quality of milk available for cheese manufacturing.
Carcass quality of Criollo Cordobes and Anglo Nubian suckling kids: Effects of age at slaughter
Pe?a,F.; Bonvillani,A.; Morandini,M.; Freire,V.; Domenech,V.; García,A.;
Archivos de Zootecnia , 2011, DOI: 10.4321/S0004-05922011000200007
Abstract: the objective of this study was to assess the carcass characteristics of two goat breed types reared under extensive system. forty male kids, 20 criollo cordobes and 20 anglo nubian, were used. the animals were slaughtered at 60±2 days old (group i) and at 90±3 days old (group ii). the carcass yield and fatness was significantly higher in anglo nubian than in criollo cordobes kids. breed and age at slaughter significantly affect carcass conformation, some carcass measures and indices, and non-carcass components.
Theoretical and experimental study of the effects of scale-up on mixing time for a stirred-tank bioreactor
Bonvillani, P.;Ferrari, M. P.;Ducrós, E. M.;Orejas, J. A.;
Brazilian Journal of Chemical Engineering , 2006, DOI: 10.1590/S0104-66322006000100001
Abstract: mixing time is one of the criteria most widely used to characterize mixing intensity in bioprocesses. in bioreactors, mixing mainly depends on amount of energy consumed, reactor and stirrer shapes, airing speed and the rheology of the medium. in this work we experimentally determined the mixing times for a lab-scale bioreactor equipped with a stirrer propelled by two rushton turbines. from these experiments we could obtain expressions to evaluate the effects of stirring speed, superficial gas velocity, specific power consumption and system geometry on mixing times under various flow regimes. the resulting correlations were employed to analyze the effect of scale-up on mixing times for the production of staphylococcus aureus smith.
Genetic polymorphism of milk protein loci in Argentinian Holstein cattle
Bonvillani Adriana Gloria,Di Renzo Miguel Angel,Tiranti Iván Nicolás
Genetics and Molecular Biology , 2000,
Abstract: Some alleles of milk protein loci are associated with superior cheese production characteristics. The genetic polymorphism of the milk protein loci alphas1-casein, beta-casein, k-casein and beta-lactoglobulin was examined in Argentinian Holstein cattle. Samples from 12 herds of four regions of Córdoba were analyzed by starch gel electrophoresis. The chi2 test was used to assess whether the populations were in Hardy-Weinberg equilibrium. Genotypic diversity was analyzed by the Shannon-Weaver index. The observed genotypic frequencies were analyzed by Hedrick's genetic identity and the genetic distance of Balakrishnan and Sanghvi. The allelic and genotypic frequencies were similar to those of other Holstein populations. The genotypic frequencies of the alphas1-casein and beta-casein loci were in equilibrium, whereas in some populations the k-casein and beta-lactoglobulin loci were not. According to the Shannon-Weaver index the total genetic diversity within each herd was greater than 96%. The high values of identity agreed with the low genetic distances among populations. We conclude that there is extensive genetic homogeneity in Holstein cattle in Córdoba Province and that it would be feasible to select for B alleles at the k-casein and b-lactoglobulin loci in order to improve the quality of milk available for cheese manufacturing.
Integration of Highly Qualified Sub-Saharan Immigrants in Prague  [PDF]
Andrea Gerstnerová
Sociology Mind (SM) , 2011, DOI: 10.4236/sm.2011.12006
Abstract: Successful integration of immigrants into the host society demands a creation of specific conditions that would facilitate immigrants their adaptation to a new sociocultural, economic and political environment. Therefore, the process of integration itself is not only a task for immigrants, but also for a majority. One of the key factors for a creation of truly cohesive society is the support of positive aspects of mutual inter-cultural relations. This could be reinforced by implementation of “adequate” integration programs adapted to the local context as well as sensible use of mass media. If the host society does not dispose of effective instruments to integrate its “own citizens”, it is generally difficult to create strategies for insertion of immigrants of different cultural backgrounds (such as Sub-Saharan Africans). Basic features of the integration process of Sub-Saharan Africans and political reactions of the major society were identified in Prague, Paris, London and Liege.
Undesired Excess Capacity and Equilibrium in an Advanced Market Economy  [PDF]
Andrea Pannone
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.411079
Abstract:

In this paper I attempt to give theoretical foundation to the concept of undesired excess capacity that I define as an unwilling, persistent mismatch between productive capacity and final demand. Undesired excess capacity has traditional room only in oligopolistic framework, like in Keynesian and Post-Keynesian models. Otherwise I show the possibility of its existence (and persistence) also with reference to a perfectly competitive economy where firms use massively information and communication technologies (ICT). In this stylized economy, undesired excess capacity is associated with “ex-post sunk costs, in terms of mismatch between total revenues and production costs. My approach, which draws a production theory alternative to the neoclassical one, makes it possible to account for these costs and connect them to the role of money, under the form of credit, in the continuation of the economic process. Moreover, in the conclusion of this paper, I show how the notion of equilibrium that emerges from the analysis could be useful to address the issue of dynamics.
