Una revisión histórico-política de la producción literaria puertorriqueña. Entrevista con Fernando Feliú Matilla / A historical and political review …
2017
Resumen: A lo largo de la siguiente entrevista, el profesor, historiador, crítico e investigador la de la Universidad de Puerto Rico, el catedrático en literatura puertorriqueña don Fernando Feliú Matilla, nos permite establecer una visión histórica de la génesis artística llevada a cabo en la Isla a través de los diferentes contextos socio-políticos que han tenido lugar en la misma desde la aparición de una literatura puertorriqueña propia y distintiva hasta la anexión de Puerto Rico a los Estados Unidos de América como Estado Libre Asociado en 1952 y su impronta en la génesis isleña. Si bien la entrevista tiene como objeto principal la literatura boricua, también se debaten en la misma el…
The Marvelous History of the Dominican Republic in Junot Diaz's The Brief Wondrous Life of Oscar Wao
2013
Few things are as noticeable in Junot Diaz’s The Brief Wondrous Life of Oscar Wao (2007) as its references to a wide variety of movies, TV series, comics, and most centrally to fantasy, the genre in which worlds are created that allow for the existence of magic, monsters, and other elements of the marvelous. Interweaving the story of the fictional Cabral family in the Dominican Republic and in the diaspora with the history of the dictatorship of Rafael Trujillo (1930–1961), the novel offers a sweeping reinterpretation of Caribbean history in a way that is completely intelligible only if one understands the relevance of its primary fantasy intertext, The Lord of the Rings (1954–55), both for…
Conservation of type III secretion system genes inBradyrhizobiumisolated from soybean
2006
International audience; The distribution of rhcRST genes encoding the type III secretion system (T3SS) in a collection of Bradyrhizobium strains was characterized by PCR and Southern blot hybridization. The polymorphism of the corresponding sequences amplified by PCR was characterized by RFLP and sequencing together with those available in the databank. Genomic group I is characterized by the presence of Bradyrhizobium elkanii strains and group II by the presence of B. japonicum and B. liaoningense strains. Highly conserved T3SS-like genes were detected by PCR in all Bradyrhizobium strains isolated from soybean belonging to genomic group II, and in none of the strains belonging to genomic g…
Effect of natamycin on the enumeration, genetic structure and composition of bacterial community isolated from soils and soybean rhizosphere
2004
Natamycin is commonly used to control fungal growth on agar media used for bacterial enumeration or strain isolation. However, there is no conclusive report on the possible effect of this antibiotic on bacterial growth or on the diversity of the recovered soil bacteria. Therefore, the possible effects of natamycin on the numbers of bacteria isolated at 12 degrees C from three different soils and soybean rhizosphere soil were investigated using natamycin concentrations ranging from 0 to 200 mg l(-1). Our results demonstrate that natamycin concentrations, which inhibit the growth of fungi on the media, have a small but significant inhibitory effect on the number of bacterial colony forming un…
Direct determination of oleic acid in soybean oil by capacitively coupled contactless conductivity detection capillary electrophoresis in an oil-misc…
2014
Este trabalho teve por objetivo desenvolver um método analítico direto e rápido para a determinação de ácido oleico em óleo de soja por eletroforese capilar com detecção condutométrica sem contato. O eletrólito de corrida empregado foi uma mistura metanol/1-propanol (1:6 v/v) contendo 4 × 10-2 mol L-1 de KOH e 10% (v/v) em etileno glicol. As amostras foram preparadas pela solubilização de 50 g L-1 de óleo de soja e 1,33 × 10-3 de ácido salicílico (padrão interno) no eletrólito de corrida. Os ensaios quantitativos foram realizados adicionando ácido oleico puro às amostras, na faixa entre 0,53 e 2,13 × 10-3 mol L-1. Sob polaridade negativa, os solutos aniônicos deslocaram-se mais rapidamente …
On-line gel permeation chromatography–attenuated total reflectance–Fourier transform infrared determination of lecithin and soybean oil in dietary su…
2007
Gel permeation chromatography (GPC) with attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectrometry detection has been proposed for the simultaneous determination of lecithin and soybean oil in dietary supplements. The method involves the extraction of analytes with dichloromethane in an ultrasound water bath and the injection of 2 ml of centrifuged and filtered extracts into the system integrated by two Envirogel GPC columns (19 mm x150 mm, 19 mm x 300 mm) coupled on-line. Dichloromethane was used as mobile phase. A method has been developed to select the most appropriated wavenumber to be used for the determination of each considered compound from the calculation of a…
Sistemas de atención a la educación infantil en América Latina y El Caribe (AL y C)
2019
El propósito de este artículo se centra en conocer cómo se estructuran los sistemas educativos de los países de América Latina y la Región de Caribe respecto al tramo de la primera infancia. Se llevó a cabo el análisis de diversos informes internacionales y documentos oficiales sobre los avances de los programas en cuanto a cobertura, inversión, regulaciones, entre otros. La naturaleza de carácter documental de este trabajo permite una aproximación comparada entre los países acerca del modo en que aborda la escolarización de la primera infancia en cada país de la región. Uno de los logros más destacados es el vinculado a la expansión del primer nivel educativo y a la cobertura alcanzada. Ca…
Assessing the performance of the Latin American and Caribbean banking industry: Are domestic and foreign banks so different?
2015
AbstractThis paper studies the relative performance of domestic and foreign banks in the Latin American and Caribbean banking industry. Data Envelopment Analysis is used to compute technical efficiency scores for the years 2001 and 2013. Our main contribution is twofold. On the one hand, we assess performance at the level of the management of specific production factors. On the other hand, we distinguish program efficiency from managerial efficiency, which allows us to evaluate whether the differences in technical efficiency between national and foreign banks are due to the use of different technologies (program efficiency) or, conversely, differences in the managerial capacities of manager…
In Vitro Dialyzability of Zinc from Different Salts Used in the Supplementation of Infant Formulas
1999
Seven zinc salts--acetate, chloride, lactate, sulfate, citrate, gluconate, and oxide--were added to milk--and soy-based infant formulas to estimate possible differences in zinc availability depending on the type of salt used. For this purpose, an in vitro method that estimates the dialyzability of the element (i.e., the fraction available for absorption) was applied. Zinc dialyzability is always higher in milk-based products than in soy products, even when the total zinc contents are higher in the latter. The salts can be classified according to the zinc dialyzability in the two types of formulas as follows: oxidegluconate = chloride = lactatecitrate = acetatesulfate. Therefore, according t…
