ABSORCIóN DE AHORRO INTERNO POR EL GOBIERNO NACIONAL
PEDROZA CAMPO,áLVARO JOSé;
Estudios Gerenciales , 2002,
Abstract: el gobierno colombiano ha financiado durante los últimos cinco a?os el déficit fiscal en gran medida con recursos provenientes del ahorro nacional, a través de emisiones de títulos en condiciones de rentabilidad innecesariamente altas, frenando la tendencia de disminución de tasas de interés internas. adicionalmente, la estructura institucional gubernamental a través de la cual se realiza la colocación primaria y la negociación secundaria de dichos títulos, genera una competencia desigual que desplaza a los demás agentes económicos, especialmente el sector productivo, como captadores de recursos del mercado de capitales para financiar sus negocios. lo anterior ha ocurrido en un período caracterizado por crisis del sector financiero y recesión económica.

Adicionalmente, la estructura institucional gubernamental a través de la cual se realiza la colocación primaria y la negociación secundaria de dichos títulos, genera una competencia desigual que desplaza a los demás agentes económicos, especialmente el sector productivo, como captadores de recursos del mercado de capitales para financiar sus negocios.

Analysis of the relation between organic products consumption and box schemes use in Alicante (Spain)  [PDF]
Fernando Vidal, David Bernardo López, Francisco José del Campo
Agricultural Sciences (AS) , 2011, DOI: 10.4236/as.2011.24065
Abstract: Box-schemes or organic food subscription plans consist on a regular delivery of a box of seasonal fruits and/or vegetables, preferably organic, cultivated in the vicinity at a specified point using subscription, The object of the present work is trying to examine whether there is a relationship between consumer knowledge about these short distribution channels and the consumption of organic products in the province of Alicante. A survey has been conducted among 400 usual food buyers in this Spanish province. It has been found that the consumption of organic products and the knowledge of such initiatives are linked. We recommend to companies that use this type of distribution channel to publicize its benefits.
Residual effects of successive exposure of soybean Bradyrhizobium strains to aluminium on solid defined medium
Campo, Rubens José;Wood, Martin;
Pesquisa Agropecuária Brasileira , 2001, DOI: 10.1590/S0100-204X2001001100011
Abstract: the aim of these studies was to investigate whether residual toxic effects of exposing soybean root nodule bacteria to al in a solid defined media (sdm) alter tolerance to al, survival, sensitivity to antibiotics, n2 fixation effectiveness and genetic diversity of bradyrhizobium strains. after being exposed four times to al, strains showed variation in al tolerance but there was no evidence of change in their original al tolerance, sensitivity to the antibiotics or genetic diversity. exposure of bradyrhizobium strains to sdm plus al did not alter biological n2 fixation effectiveness of five strains. strain semia 587 showed a reduction in its n2 fixation effectiveness but it seems that it was just a superficial toxic effect because one single passage through the plant eliminated this effect. residual al did not cause increases in al tolerance and reductions in the survival and n2 fixation effectiveness of bradyrhizobium strains usda 143, semia 586, semia 5019, semia 5039 and semia 5073. it also did not alter the resistance to antibiotics of strains usda 143, semia 5039 and semia 5073, and the genetic diversity of the strains semia 587 and semia 5019.

After being exposed four times to Al, strains showed variation in Al tolerance but there was no evidence of change in their original Al tolerance, sensitivity to the antibiotics or genetic diversity. Exposure of Bradyrhizobium strains to SDM plus Al did not alter biological N2 fixation effectiveness of five strains. Strain SEMIA 587 showed a reduction in its N2 fixation effectiveness but it seems that it was just a superficial toxic effect because one single passage through the plant eliminated this effect. Residual Al did not cause increases in Al tolerance and reductions in the survival and N2 fixation effectiveness of Bradyrhizobium strains USDA 143, SEMIA 586, SEMIA 5019, SEMIA 5039 and SEMIA 5073. It also did not alter the resistance to antibiotics of strains USDA 143, SEMIA 5039 and SEMIA 5073, and the genetic diversity of the strains SEMIA 587 and SEMIA 5019.

Observational Constraints on the Generalized Chaplygin Gas
Sergio del Campo,José Villanueva
Physics , 2009, DOI: 10.1142/S0218271809015795
Abstract: In this paper we study a quintessence cosmological model in which the dark energy component is considered to be the Generalized Chaplygin Gas and the curvature of the three-geometry is taken into account. Two parameters characterize this sort of fluid, the $\nu$ and the $\alpha$ parameters. We use different astronomical data for restricting these parameters. It is shown that the constraint $\nu \lesssim \alpha$ agrees enough well with the astronomical observations.
Efeito de fontes e doses de molibdênio na sobrevivência do Bradyrhizobium e na fixa??o biológica de nitrogênio em soja
Albino, Ulisses Brigatto;Campo, Rubens José;
Pesquisa Agropecuária Brasileira , 2001, DOI: 10.1590/S0100-204X2001000300018
Abstract: molybdenum (mo) is an essential nutrient for soybean because it is a component of enzyme nitrogenase, responsible for the biological nitrogen fixation (bnf). it has been recommended for application on soybean seeds along with soybean inoculants. however, several works have showed that mo applied together with inoculant reduce bradyrhizobium survival, nodulation and bnf efficiency. the aim of this study was to know if there are alternative ways to supply mo to soybean without affecting bradyrhizobium strains survival, nodulation and bnf efficiency. the alternative ways studied in vitro were to know the growth of strains in liquid medium with different sources and levels of mo, and in glasshouse these sources of mo were compared with the commercial ones on their effects on bacteria survival on the seeds, nodulation and bnf efficiency. the strains of bradyrhizobium showed different growth rate for the mo concentration and sources tested, being the strain semia 5080 the best of them. mo application on the seeds must be avoided, because mo reduces bacteria survival, nodulation and, bnf efficiency. the best mo sources to bnf were ammonium molybdate, mo trioxide and the commercial sources grap and comol.
