Description
An account of the resource
Introduction: Mentha spicata, commonly known as spearmint, is the most common and popular cultivated mint, and is used in food, perfumes and pharmaceutical products. Objective: To determine the yield, composition and properties of essential oil from M. spicata grown in Santiago del Estero, Argentina. Methods: We used steam distillation, gas chromatography and mass spectrometry to determine chemical composition, antioxidant activity and acetylcholinesterase inhibition. Results: Essential oil yield ranged from 0.8 to 1.3 mL·100 g-1 DM. The main essential components were carvone (60,72-68,09%), limonene (14,23-16,41%), α-pinene (0,12-3,14%), β-myrcene (0,35-2,33%), 1,8-cineole (1,69-2,73%), cis-dihydrocarvone (1,82-2,31%), trans-craveol (1,09-1,19%), β-bourbonene (2,44-3,17%) and β-Caryophyllene (1,42-1,82%). The oil had high antioxidant activity, with IC50 values among 7,5-12,06 µg/mL (DPPH method) and 26,94-38,14 µg/mL (β-carotene/linoleic acid method). It had good inhibition of acetylcholisterenase, with enzyme inhibition zones of 0,4-0,9 cm. Conclusion: The yield, quality and properties of the essential oil from M. spicata grown in Santiago del Estero meet market requirements.

An account of the resource
No obstante los cambios acaecidos en la últimas dos décadas y las recurrentes crisis que afectan al globo desde el inicio de este siglo (de seguridad, alimentaria, energética y -finalmente- financiera) empiezan a marcar un rumbo diferente y con él resurgen con fuerza las reuniones internacionales y los estudios sobre el valor de la cooperación internacional, su gestión, potencialidades y desafíos. Aparecen en consecuencia nuevos argumentos para sostener el papel fundamental que juega la cooperación internacional en nuestros días y sus reflejos en la realidad: de la tradicional cooperación Norte-Sur hemos pasado a formas de cooperación Sur-Sur y triangular; del protagonismo excluyente de los Estados hemos avanzado en la inclusión de nuevos actores, hoy fundamentales, como lo son el sector privado y a la sociedad civil organizada; de formas de gestión lineales hemos pasado al debate plural y abierto. Llegado este punto debo decir que es particularmente alentador revisar el origen de los trabajos que integran este dossier.

Um experimento foi desenvolvido em ambiente telado do Departamento de Solos e Engenharia Rural da Universidade Federal da Paraíba, Areia, PB, no período de janeiro a abril de 2010. O substrato constou de material de um Neossolo Quartzarênico não salino, coletado na camada de 0-20 cm. Os tratamentos foram dispostos em delineamento inteiramente casualizado em esquema fatorial 5 x 2, referente aos níveis de salinidade da água de irrigação de 0,5; 1,0; 2,0; 3,0 e 4,0 dS m-1, no solo sem e com biofertilizante comum, aplicado ao solo uma única vez, após diluição em água, na proporção de 1:1, um dia antes da semeadura, em volume correspondente a 10% do volume do substrato. Aos 86 dias após a emergência das plântulas normais avaliaram-se o crescimento em altura e o comprimento da raiz, diâmetro do caule e da raiz, número de folhas e a massa seca das raízes e parte aérea das plantas. O conteúdo salino da água de irrigação elevou a condição salina do substrato ao ponto de comprometer o crescimento em altura e diâmetro do caule, número de folhas, diâmetro e comprimento da raiz principal, massa seca das raízes e parte aérea (folhas + caule) do nim mas com declínios menos pronunciados nos tratamentos com biofertilizante bovino.An experiment was carried out in greenhouse during the period January to April 2010, at Center of Agricultural Sciences of the Federal University of Paraiba, in Areia, Paraiba State, Brazil, in order to evaluate the effects of saline water and bovine biofertilizer on the seedling growth of Indian neem. The substrate was material of a non-saline soil collected in depth of 0-20 cm. The treatments were arranged in a completely randomized design using a 5 x 2 factorial, referring to salinity levels of irrigation water of 0.5, 1.0, 2.0, 3.0 and 4.0 dS m-1, with and without bovine biofertilizer applied to the soil only once after dilution with water (1:1), a day before sowing, in volume corresponding to 10% of the substrate. At 86 days after emergence of seedlings the plant growth in height and principal root length, diameter of stem and root, leaf number and dry mass of roots and shoots of plants were evaluated. The salinity of irrigation water increased the salinity levels in the substrate inhibiting the growth in height, stem diameter, leaf emission by plants, diameter and length of principal root and the dry matter production of roots and aerial parts (leaves + stem) of neem, but with less pronounced decrease in plants under the treatments with bovine biofertilizer.

Description
An account of the resource
The goal of this paper is to present a proof that for the logistic map the period-3 begins at . The third-iterate map is the key for understanding the birth of the period-3 cycle. Any point in a period-3 cycle repeats every three iterates by definition. Such points satisfy the condition ,and they are therefore fixed points of the third-iterate map. This fact and the so called tangent bifurcation for the logistic map, as well as the fixed points definition, are used for finding the value. The algebraic treatment utilizes some properties of symmetric polynomials in three variables. For the purposes of this paper, the bifurcation diagram for the logistic map is also presented, as well as a program in Mathematica for its construction.

El objetivo del presente trabajo será presentar información empírica sobre la historia y práctica actual de la Red de Agroecología del Uruguay, aportando interpretaciones posibles desde el enfoque sobre los antagonismos sociales rurales. Se trata de un estudio transversal no experimental, con triangulación de métodos (cualitativos y cuantitativos) y utilización de tres técnicas de recolección de datos: observación de plenarios, entrevistas colectivas y encuesta autoadministrada. Los resultados permiten concluir que, en los últimos años, fueron configurándose en Uruguay, tramas sociales locales de producción, distribución y consumo de alimentos agroecológicos, que, aun de forma precaria, sostienen prácticas y narrativas de resistencia al modelo hegemónico.

Description
An account of the resource
In this work, a risk index to monitor an anaerobic digestion process is established. The index is derived from the dynamical analysis of the system and it is composed by two conditions ensuring an optimum operating conditions inside bioreactor. The analysis is performed using bifurcation theory in order to study the effects of dilution rate, temperature and pH parameters at behavior system. For these purpose an extended version of the mathematical model proposed by Bernard [1] involving the dependence of growth kinetics on temperature and pH is used. The analysis shows both microbial growth and the performance of the bioprocess, when is highly affected by these parameters, indeed the washout condition occurs by combining a fold bifurcation and a transcritical bifurcation. From bifurcation diagrams both safety and optimal operation regions of the bioreactor are defined. Consequently, based on two conditions of stability a risk index to monitor the bioprocess on-line is proposed. The index is evaluated via numerical simulations allowing to detect system destabilization. The results obtained in this work may provide a useful methodology to monitor an anaerobic process and to guarantee the optimal performance of the bioreactor given that the model is sufficiently accurate.
