Abstract: Con la finalidad de evitar infecciones por mastitis en el ganado vacuno, es recomendable utilizar sellador de pezones post orde o. El objetivo del trabajo fue desarrollar un sellador post orde o antiséptico y con estabilidad fisicoquímica, para evitar pérdidas del producto por escurrimiento. El sellador se formuló con la goma espina corona, que cumple la función de incrementar la viscosidad del producto. Se aplicó el dise o central compuesto rotable para obtener la formulación óptima. Se evaluó la viscosidad aparente, como variable de respuesta con un viscosímetro Brookfield DVII+LV2. Se determinó la fórmula óptima: espina corona (1,7%), agua desmineralizada (88.60%), glicerina (4,70%), solución de yodo y tensioactivo (3,00%) y solución buffer pH=5±0.3 (2,00%). El sellador mostró un comportamiento reológico del tipo pseudoplástico. Se concluye que la goma espina corona es apta para formular un sellador post orde o, tiene estabilidad fisicoquímica adecuada y mantiene su principio activo como bactericida. To prevent infection by mastitis in cattle, it is advisable to use post milking teat dip. The objective of this study was to develop a post milking antiseptic sealant with physicochemical stability, to avoid product losses by leakage. The sealant was formulated with the espina corona gum, which increases the viscosity of the product. A central composite rotatable design was applied to obtain the optimal formulation. The apparent viscosity was evaluated as the response variable with a Brookfield DVII + LV2. The optimal formula was determined as: espina corona gum (1.7%), dematerialized water (88.60%), glycerin (4.70%), iodine solution and surfactant (3.00%) and buffer solution pH = 5±0.3 (2.00%). The sealant showed a rheological behavior of the pseudoplastic type. It is concluded that the espina corona gum is suitable to formulate a post milking sealant with acceptable physicochemical stability and that also keeps its active principle as a bactericide.

Abstract: Se presenta una actividad colaborativa de matemática sobre el tema de vectores y rectas en el espacio. La metodología en la que se basa esta actividad es la del rompecabezas. Así, luego de una parte individual en la que cada estudiante demostrará cuán preparado está, se continuará con un trabajo en parejas donde cada una tendrá una tarea distinta para, luego, terminar con un trabajo más complejo en el que las parejas deberán integrar lo trabajado en la etapa previa.
Fishers' knowledge and seahorse conservation in Brazil
Ierecê ML Rosa, R?mulo RN Alves, Kallyne M Bonifácio, José S Mour?o, Frederico M Osório, Tacyana PR Oliveira, Mara C Nottingham

Abstract: Over a decade ago, Ruddle [1] pointed out the great potential value of local knowledge as an information base for local management of marine environments and resources, especially in the tropics, where conventionally-used data were usually scarse to non-existent. A number of subsequent studies have documented and recognized the value of local knowledge to conservation and management of fisheries [2-12].A pragmatic view of the relevance of fishers knowledge to fisheries management has been expressed by Ames [8]: "fishermen and their subjective, anecdotal descriptions have a pivotal role to play in the development and function of sustainable fisheries (.......) fishermen are, in fact, the only available source of local, historical, place-based information". Nevertheless, lack of sound management practices have led to the collapse of particular types of fisheries in some parts of the world, and, as pointed out by Meewig et al. [13], interest in participatory approaches in resource management in part reflects the failure of top-down, centralized approaches to manage natural resources.Definitions of artisanal, subsistence fisheries have traditionally focused on the capture and trade of food fish. However, a growing number of examples of fish species being traded worldwide for purposes other than alimentary (e.g., as pets, remedies, souvenirs) has revealed the existence of an international and multi-faceted commerce, supported by a diffuse (and generally poorly quantified) harvesting of a number of species.Those forms of exploitation have received little attention when compared with the trade of animals for alimentary purposes [14]. In the marine realm, the scarcity of data has rendered the identification of key elements for conservation and management, and the assessment of impacts difficult.Seahorses (Hippocampus spp.) are among the few non-food marine fishes whose trade has been documented, initially in Asia [15], where the demand for those fishes was primarily for use

Abstract: El análisis se realizó en un corregimiento del municipio de Mutatá (Urabá Antioque o). éste, entre 1975 y 1989 estuvo controlado por las organizaciones guerrilleras; posteriormente pasó al dominio de las organizaciones paramilitares. El propósito es analizar la forma en que se ha configurado el campo religioso, las relaciones que se establecieron entre las 13 iglesias existentes y el pa- pel que desempe an en un contexto marcado por el con- flicto armado.
Análisis de las correlaciones en poblaciones cubanas de maíz
Mart ínez,M; Ortiz,R; Ríos,H; Acosta,Rosa;
Cultivos Tropicales , 2010,
Abstract: an analysis of pearson′s correlations (r) present in cuban maize populations was performed in this research study. consequently, correlations were found in most of the populations studied, such as those recorded between grain number per row (nogh) and cob length (lm), mean cob diameter (dmm) and row number (noh), as well as grain number per cob (nogm) and grain number per row (nogh). there are other specific correlations of each population studied. significant correlations were also proved when comparing morphological characters and those of nutritional quality, which enable to make selection indirectly in breeding programs. in this sense, the highest correlations are firstly the ones showing row number and tryptophan (trp) content in a negative manner whereas positively with sodium (na) content. correlations between quality characters are low but biologically important, showing what nutrient contents are directly or indirectly related among them. it is important to remark that the content of both essential amino acids (lysine and tryptophane) greatly determining maize protein quality has a very significant and positive correlation to each other in this population, which implies that increasing one amino acid content is directly equivalent to increasing the other one or vice versa, in such a way that protein quality becomes considerably higher or lower

Estudios de historia moderna y contemporánea de México , 2009,
Abstract: this article analyzes the case of alberto nicolat talocín: a paranoic that was hospitalized several times in the lunatic asylum la casta?eda. on the basis of their autobiographies and the thesis written by doctor gregorio oneto barenque, the author reconstruct the way "madmen" related to therapeutic institutions and psychiatric language. they also discuss the role of the mentally ill and the cultural context of the construction of scientific knowledge of psychopathies.
LOCURA Y ENCIERRO PSIQUIáTRICO EN MéXICO: EL CASO DEL MANICOMIO LA CASTA?EDA, 1910
Ríos Molina,Andrés;
Antipoda. Revista de Antropología y Arqueología , 2008,
Abstract: the manicomio general la casta?eda founded in 1910 at the outside of mexico city, was the most important psychiatric institution of the xxth century in mexico. when it was open, the families let there men and women whom had the requirement for being considered madness and in consequences, they where appropriate for having psychiatric treatment. in this article i explore the cultural bases of the therapeutic confinement through the imaginaries that the mexican society of those days had about madness, its causes, symptoms and treatments. it analyzes both faces of madness: the one of the degenerate and the other of the nervous. both refierences synthesize psychiatric terms and social variables as class and gender.

Antipoda. Revista de Antropología y Arqueología , 2008,
Abstract: El Manicomio General La Casta eda fundó en 1910 en las afueras de la Ciudad de México, fue la institución psiquiátrica más importantes del siglo XX en México. Cuando estaba abierta, las familias permiten que hombres y mujeres que tenían la obligación para ser considerado una locura y, en consecuencias, en su caso para tener un tratamiento psiquiátrico. En este artículo voy a explorar las bases culturales de la confnement terapéutico a través de los imaginarios que la sociedad mexicana de aquellos días sobre la locura, sus causas, síntomas y tratamientos. Se analizan las dos caras de la locura: la de los degenerados y la otra del sistema nervioso. Ambas referencias sintetizar términos psiquiátricos y variables sociales como la clase y de género.
