Los efectos del programa Bolsa Família en el consumo familiar

El objetivo es evaluar los efectos del programa Bolsa Família (PBF) en los gastos de las familias beneficiarias en: alimentos, frutas, carnes y pescados, aves y huevos, verduras, cereales y oleaginosas, harinas y pastas, tubérculos y raíces, azúcar, productos de panadería, bebidas alcohólicas, educación, higiene, salud y materiales escolares. En la estimación se utilizaron microdatos de la Encuesta de Presupuestos Familiares del Brasil 2008-2009. La metodología para calcular el efecto medio del tratamiento en los tratados fue el emparejamiento por puntaje de propensión (propensity score matching). Los resultados fueron estadísticamente significativos respecto de los gastos en: i) alimentos; ii) aves y huevos; iii) legumbres y verduras; iv) cereales, leguminosas y oleaginosas; v) harinas, féculas y pastas; vi) tubérculos y raíces; vii) azúcares y derivados, y viii) artículos escolares. Se observa que las familias beneficiarias aumentaron la adquisición de bienes prioritarios y de materiales escolares, que suponen una inversión en educación.

Quantificação de contaminantes em aguardentes de cana/cachaças de alambique e de coluna

In the present study aimed to characterize and quantify four contaminants (ethyl carbamate, 2,3-butanedione, furfural and 5-hydroxymethylfurfural) present in alembic cachaça and industrial. Were collected forty-four samples of cachaça in the southern regions, the Midwest, southeast of Minas Gerais and São Paulo state, and subsequently subjected to physical, chemical and chromatographic analyzes. The physicochemical analyzes were performed according to the methodology described by the Ministry of Agriculture, Livestock and Supply (MAPA). The ethyl carbamate, 2,3-butanedione, furfuaral and 5 hydroxymethylfurfural were characterized and quantified by high-performance liquid chromatography (HPLC). The results of the ethyl carbamate analysis, it was found that both samples showed column cachaças outside the standards required by law, with the values 245.31 235.53 L-1 ug and none of the liquor samples alembic showed concentration greater than 210.0 ug L-1 , and the method is very sensitive to low limits of detection and quantification. In determining 2,3-butanedione, it was revealed that the column cachaças showed higher levels of contaminants when compared to cachaça alembic. In the quantification of furfural and 5-hydroxymethylfurfural was developed and validated analytical methods employed to high-performance liquid chromatography (HPLC) with DAD detector. Samples column cachaças showed higher values than the limit established by Brazilian legislation and ranged from 7.00 to 5.63 mg / 100 ml of anhydrous alcohol over the alembic cachaça.

Caracterização fisiológica e produção de metabólitos secundários em Achillea millefolium L. após aplicação de quitosana

Elicitation with chitosan is a tool used to improve the responses of plant defense by inducing secondary metabolism routs. In addition, the adequate application of this elicitor on medicinal plants can promote the increase of major components in the composition of the oil. However, we lack information concerning which are the main physiological processes responsible for the changes in the composition of the oil. Thus, we aimed at evaluating the action of chitosan and determine an ideal concentration for optimizing the production of essential oil in Achillea millefolium L. and the changes in the physiological processes responsible for this increase. The research was conducted in greenhouse of the Plant Physiology sector of the Universidade Federal de Lavras (UFLA) with A. millefolium plants. The treatments consisted of control (water); acetic acid solvent (with no elicitor); and chitosan in the concentrations of 2, 4 and 6 g L -1 . The measurements of growth, gas exchange, enzyme activity of the antioxidant system and phenylalanine ammonia lyase (PAL), in addition to the production and composition of the essential oil. We verified that the application of chitosan promoted decrease in plant growth. However, the concentration of 4 g L -1 of chitosan induced an increase in the content and yield of the essential oil. In the oil, there was predominance of sesquiterpenic compounds, including the major compounds borneol, β-caryophyllene, β-cubebene, α-farnesene and chamazulene. The elicitation with chitosan at 4 g L -1 promoted an increase of the photosynthetic rate, activity of the antioxidant system and of PAL, however, this increase occurred in short-term, only in the first days after elicitation.

Influência do etileno na regulação do florescimento de Coffea arabica L.

Coffee is one of the most valuable exported agricultural product worldwide as well as the second most traded commodity after oil. This crop represents a source of employment and considerably accounts for the revenue of the country, besides its undeniable importance for local and world socioeconomical scenery. The quality of the coffee drink is directly related to the fruit ripening stage, which is found in different stages at harvesting due to the sequential flowering, increasing costs with the production and generating a lower-quality beverage. The asynchronous flowering of the coffee tree comes from the uneven development of buds, which can be influenced by environmental factors, taking into account that the anthesis takes place after a water deficit period, followed by precipitation. Changes in the hormone balance have been observed after water deficit and rehydration cycles, and such oscillation on the water status of the plant increased the level of ethylene in some species. This finding led to the association between the requirements at the flowering stage of the coffee tree and the involvement of the ethylene in promoting anthesis. The application of 1- MCP (ethylene action inhibitor) triggered the anthesis in coffee trees. And, in coffee seedlings in greenhouse conditions after a period of water shortage followed by irrigation, the profile of gene expression of the biosynthesis route and signaling of ethylene are changed in leaves and roots. The increased levels of the ethylene precursor (ACC) in roots throughout the dry season and the transportation of this compound into shoots may be the signal to trigger the anthesis in coffee tree after rehydration. Thus, in order to better understand the role of the ethylene in regulation of flowering, we analyzed the effects of the exogenous application of 1-MCP in different physiological characteristics and in the expression of genes related to the ethylene biosynthesis and signaling pathways in coffee leaves and bud from plants under field conditions. The evaluations and tissue sampling were carried out in different times treatments implementation: T1 – control, T2 – 1-MCP+Break-Thru, and T3 – Break-Thru. There was influence of 1-MCP and Break-Thru in gas exchange parameters and of 1-MCP contributed to the increase in relative water content. RT-qPCR analyses showed a different behavior in relation to the profile of gene expression in leaves and buds analyzed in the present study (CaACS1 – like, CaACO1 – like, CaACO4 – like, CaETR4 – like) and the expression levels were changed a few hours (2h) after applying the products. However, there was flowering only in plants treated with 1-MCP, in the absence of rain and irrigation.
