1. Reduction of Aqueous Ag+ Steered by Electrochemical Plasma: Connecting the Bulk pH Variation with the Reaction Pathways for Hydrated Electrons
Reduction of silver cations followed by nanoparticle (Ag-NPs) synthesis is a model process to understand the reduction mechanism induced by a discharge over an aqueous surface, termed electrochemical plasma. This work aims at studying the silver reduction reaction steered by electrochemical plasma in the presence of other chemically active plasma-related int

2. Antispasmodic effects of Aloysia polystachya and A. gratissima tinctures and extracts are due to non-competitive inhibition of intestinal contractility induced by acethylcholine and calcium
The antispasmodic effects of acqueous extracts (AE) and tinctures (T) of Aloysia polystachya (Griseb.) Moldenke and Aloysia gratissima (Gillies & Hook.) Tronc., Verbenaceae, were studied on rat isolated ileum and duodenum. These plants are used for gastrointestinal disorders and as eupeptic in South America. Both AE non-competitively inhibited the dose-respo

3. AplicaÃÃo do mÃtodo MACBETH para subsidiar migraÃÃo de plataforma tecnolÃgica de redes de TelecomunicaÃÃes / Application of MACBETH method to support telecommunication network migration to MPLS
Gestores de telecomunicaÃÃes e TI precisam estar sempre atentos aos rumos da organizaÃÃo e com isso procederem a mudanÃas necessÃrias nas estruturas e redes de comunicaÃÃo que subsidiam os negÃcios da empresa. A tomada de decisÃo a respeito da migraÃÃo de tecnologias nÃo dever ser efetuada sem um mÃtodo consistente que as subsidie, livrando o g

4. Purification and characterization of cytosolic and cell wall β-galactosidases from Vigna unguiculata stems
Three β-galactosidase isoforms, β-gal I and β-gal II (cytosolic) and β-gal III (cell wall-associated), were isolated from stems of Vigna unguiculata (L.) Walp. cv. Pitiúba seedlings. Purification consisted of aμMonia sulfate fractionation followed by chromatography in DEAE-Sephadex and Lactosyl-Sepharose columns. The two cytosolic isoforms showed the s

5. Open innovation as an alternative for strategic development in the aerospace industry in Brazil
Abstract: We present in this paper a case of technological competence development in the aerospace sector in Brazil, by addressing the complete cycle of integrated circuits for satellite applications, an area of high technology which is strategic to the country. The development of technological and business competences is linked to an understanding of the ex

6. Classificação multi-rótulo hierárquica de documentos textuais
The amount of information stored in text databases is steadily increasing. As such, demand for automated techniques to organize this data also continues to grow. In this context, academic and industry research has been focused on the study of automatic text classification. Most work on text classification studies the development of techniques in which there

7. Lie symmetries and related group-invariant solutions of a nonlinear Fokker-Planck equation based on the Sharma-Taneja-Mittal entropy
In the framework of the statistical mechanics based on the Sharma-Taneja-Mittal entropy we derive a family of nonlinear Fokker-Planck equations characterized by the associated non-increasing Lyapunov functional. This class of equations describes kinetic processes in anomalous mediums where both super-diffusive and subdiffusive mechanisms arise contemporarily

8. Phosphite on the growth, phosphate nutrition and aspects of the induction of resistance in maize. / Fosfito no crescimento, nutriÃÃo fosfatada e aspectos da induÃÃo de resistÃncia em milho
The present work was intended to evaluate the effect of supplying of phosphite on the growth, phosphate nutrition and aspects of the induction of resistance in maize. An experiment in a completely randomized design was conducted in nutrient solution under greenhouse conditions, where two concentrations of P (1.6 mg L-1 = low phosphorus and 20 mg L-1 = adequa

9. Motivación y satisfacción de los trabajadores y su influencia en la creación de valor económico en la empresa
Economic value management implies that management should be interested in reaching an efficient generation of value and its fair distribution. Our society cannot be conceived only as a market because it is constituted by a community of people who participate competitively and cooperatively. They have their own motivations and act collectively by coordinating

10. Inhibition mechanism of the nicotinic acetylcholine receptor α3β4 tacrine / Mecanismos de inibição do receptor nicotínico de acetilcolina α3β4 pela tacrina
Neuronal nicotinic acetylcholine (cholinergic) receptors (nAChRs) are integral membrane proteins and belong to the family of ligand-gated cation channels composed by α and β subunits. These receptors play a key role in the signal transmission between neurons in the central and peripheral nervous system. The α3β4 subtype, for example, is t

11. Quando a terceirização não funciona: a primeirização das atividades de manutenção industrial na Caraíba Metais.
Due to the changes in the economy of the world and of Brazil, companies sought for new strategies in order to keep operating competitively. Outsourcing appeared as an alternative for the companies.By decentralizing the activities, the outsourcing process sought reduction of costs, focus in its output and raise of productivity. If initially only secondary act

12. Administração limpa e enxuta em sistemas hidraulicos de colhedoras de cana-de-açucar : uma proposta metodologica / Clean and lean administration for hydraulic systems of harvesting of sugar cane : a methodological proposal
Dentre as importantes mudanças nos processos de produção, está a necessidade de garantir sustentabilidade aos empreendimentos humanos. O progresso desordenado, provocado pelo adensamento demográfico, tem gerado problemas, quando embasado nos padrões do paradigma capitalista. Isso faz prever mudanças na gestão empresarial, para adequar-se a um novo mo
