Abstract: the effect of time different periods was compared without host in the trichogramma atopovirilia (hym.: trichogrammatidae) reproducitive characteristics fed or not. anagasta kuehniella (lepidoptera: pyralidae) and sitotroga cerealella (lepidoptera: gelechiidae) eggs they were used as hosts, being exposed to that parasitoid females after 0, 6, 12, 24, 36, 48, 60, 72, 84 or 96 hours. t. atopovirilia females, fed and sponged the hosts eggs up to 96 hours without the same ones. however, the parasitism happened until the period of 24 hours in a. kuehniella and 48 hours with s. cerealella when not fed. the t. atopovirilia parasitism, the emergency and the sexual reason were similar in a. kuehniella eggs, but with the increase of the period without that host, it decreases along the time, with s. cerealella in a similar way it was observed for those not fed. the food was the principal factor that affected in the t. atopovirilia parasitism.

Abstract: sitophilus zeamais (mots.) (coleoptera: curculionidae) is considered a major pest of maize, responsible for reducing grain quality and making the corn inappropriate for industrial use and human consumption. s. zeamais has been controlled exclusively with chemical products. the objective of this research was to select isolates of beauveria bassiana (bals.) vuill. to control s. zeamais. beetles were immersed in conidia suspensions of each isolate for five seconds and placed in a gerbox container with maize grains. in pathogenicity tests, the isolates that caused the highest mortality to the maize weevil were esalq-447 (68.0%), cca-ufes/ bb-36 (57.3%) and cca-ufes/bb-31 (51.3%). esalq-447 was the most virulent, with an lc50 of 1.7 x 107 conidia/ml and shows promise for controlling maize weevils. these isolates of b. bassiana can be used as effective substitutes for conventional chemical control, normally carried out with phosphine. further tests should be performed under field and semi-field conditions to develop an appropriate strategy for the use of this entomopathogen to manage s. zeamais.

Abstract: the objective of this work was to evaluate the parasitism capacity of trichogramma pretiosum riley and t. acacioi brun, moraes and soares (hymenoptera: trichogrammatidae) in eggs of the alternative host sitotroga cerealella (olivier) (lepidoptera: gelechiidae) aiming to use both species in biological control programs of nipteria panacea tierry-mieg (lepidoptera: geometridae). the parasitism rhythm and total parasitism of these parasitoid species were affected by the temperature with higher values during the first 24 h of their life. parasitism period was longer for t. pretiosum and t. acacioi at the lowest temperature.
Latinoamericanos en el mercado de trabajo espa ol, 2000-2005

Abstract: El objetivo de este artículo es el análisis de la inserción laboral de la población latinoamericana en Espa a durante el periodo 2000-2005, utilizando dos oleadas de la Encuesta de Población Activa (EPA). Los resultados muestran que el colectivo latinoamericano ha experimentado un proceso de rejuvenecimiento, de masculinización (aunque la población femenina continua siendo mayoritaria) y de empeoramiento de su nivel educativo medio, aunque el colectivo con nivel secundario sigue siendo predominante. Los resultados confirman la hipótesis de partida sobre la existencia de una relación entre la llegada de inmigrantes y la promoción laboral y social de la población espa ola, en un contexto de constante mejora del nivel educativo de las generaciones jóvenes autóctonas (especialmente de las femeninas).
The 2007-08 Financial Crisis from a Marxist View  [PDF]
Fernando Henrique Taques, Henrique Pavan Beiro De Souza, Douglas Alcantara Alencar
Modern Economy (ME) , 2017, DOI: 10.4236/me.2017.89074
Abstract: The international financial crisis in the American economy in 2008 brought again to the fore an economic discussion on the origin of crises. Previously, only the 1929 accident had such magnitude, putting in discussion the economic policies adopted until then, raising the economic debate between several economic schools of thought. The effects of the crisis were notorious about the financial markets, but also hit hard the real economy, especially the productive sector, such as industry and services. Indeed, the consequences on employment, income and on the level of trade were not only felt by the American economy, but also in other countries. Starting from this context, this article aims to describe the propelling elements and the forms of theoretical manifestation of the crises under a marxist perspective, seeking to understand the origins of this phenomenon from the marxist stream, as well as discourse about the 2008 crisis and its developments on the American economy. Therefore, it makes use of economic indicators on the evolution of prices and sale of real estate in the United States, growth rate of gross domestic product and employment and income between 2000 and 2010. The methodology also includes the arguments on the capital bearer of interest and fictitious capital in addition to the role of the rate of profit, exposed in the Marxist conception of the origin of financial crises. As a result, it can be seen that the fictitious capital dominates economic and political relations so that the crisis has its origin on capital and not in the productive sphere.
The Use of Sodium Silicate as a Corrosion Inhibitor in a Saline Drilling Fluid: A Nonaggressive Option to the Environment  [PDF]

Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.713157
Abstract: The function of a corrosion inhibitor in drilling mud compositions is the corrosion protection of the equipment involved in drilling operations. Many compositions involve environmentally several products such as fatty amines of high molecular weight, polyoxylated amines, amides, imidazolines, nitrogen heterocyclic products, etc. The potential advantages of the use of silicates are the effective protection of carbon steel, especially in aerated saline fluids, low costs and non-aggressive behavior to environment. Gravimetric and electrochemical tests were carried out using an aerated solution of 3.5% NaCl and the addition of sodium silicate (Na2SiO3·9H2O) as a corrosion inhibitor at concentrations of 250 to 2000 mg/L. The efficiencies of the corrosion protection of carbon steel using silicate concentrations greater than 1250 mg/L were greater than 92%.

Abstract: Utilizando datos del segundo trimestre de 2006 de la EPA, el objetivo de este artículo es el análisis estadístico (análisis factorial, regresión lineal múltiple) de los factores que determinan la distribución provincial de la población femenina extracomunitaria en edad activa (16-64 a os). Los resultados muestran la relación existente entre el porcentaje provincial de extracomunitarias y las características propias de cada provincia en lo que se refi ere tanto a su estructura demográfica y laboral como a las peculiaridades de su mano de obra femenina autóctona (nivel educativo, grado de cualificación ocupacional, tasas de actividad). Junto a otros factores como la terciarización o el grado de envejecimiento, los porcentajes provinciales de extracomunitarias están en parte determinados por la existencia de un mayor nivel de instrucción y una mayor actividad de las mujeres espa olas, validando de esta manera la hipótesis de partida: la existencia de complementariedad entre la llegada de inmigrantes extranjeros y el proceso de promoción educativa, laboral y social de la población autóctona (especialmente femenina).
Pyoderma gangrenosum and anticardiolipin antibody
de Godoy Jose Maria,Batigalia Fernando,Braile Domingo
Indian Journal of Dermatology , 2006,
Abstract: Pyoderma gangrenosum (PG) is a rare ulceronecrotic inflammatory cutaneous disorder and is frequently associated with systemic diseases. The authors report a 22-year-old male patient with pyoderma gangrenosum, thrombosis of both popliteal arteries, ischemic stroke and seropositivity for anticardiolipin antibody. Despite intravenous treatment with antibiotics, corticosteroid and heparin, pyoderma gangrenosum caused necrosis of his right lower limb which resulted in amputation. It was concluded that the anticardiolipin antibody may have contributed to the gravity of this case.
