Semi-empirical model of MOST and passive devices focused on narrowband RF blocks

Trabajo presentado al DCIS celebrado en Avignon (Francia) del 28 al 30 de noviembre de 2012.This paper presents a semi-empirical modeling of MOST and passive elements to be used in narrowband radiofrequency blocks for nanometer technologies. This model is based on a small set of look-up tables (LUTs) obtained via electrical simulations. The MOST description is valid for all-inversion regions of MOST and the data is extracted as function of the gm=ID characteristic; for the passive devices the LUTs include a simplified model of the element and its principal parasitic at the working frequency f0. These semi-empirical models are validated by designing a set of 2.4-GHz LNAs and 2.4-GHz and 5-GHz VCOs in three different MOST inversion regions.This work has been financed in part by the Junta de Andalucía project P09-TIC-5386 and the Ministerio de Economia y Competitividad project TEC2011-28302, both of them co-financed by the FEDER program.Peer Reviewe

Effects of concomitant benzodiazepines and antidepressants long-term use on social decision-making: results from the ultimatum game

Benzodiazepines and antidepressants have been shown to change responses to unfairness; however, the effects of their combined use on unfairness evaluation are unknown. This study examines the effects of concomitant benzodiazepines and antidepressants long-term use on the evaluation of fair and unfair offers. To analyze behavioral changes on responses to unfairness, we compared the performance of medicated participants and healthy controls in the Ultimatum Game (UG), both in the proposer and in the respondent role. The results showed that long-term psychotropic users had the worse economic strategy by accepting less offers than control subjects. However, in the proposer role, the unfair offers made by participants were similar between groups. The present results suggest that long-term use of psychotropic medication, specifically the combination of benzodiazepines and antidepressants, may increase the sensitivity to unfairness, resulting in higher rejection rates in conditions where this strategy is the most disadvantageous

Cidadania e participação social

Pois é exatamente aqui que se coloca o presente livro: é um grupo de cidadãos/ãs que decidem dizer sua palavra, na nova “agorá”, que é a discussão e construção teórica que se realiza nas academias e nas práticas sociais. Esse livro não é somente “fala”: ele é ação, ele é dimensão essencial na construção da cidadania através da participação consciente e crítica dos diversos atores/ autores/as que a ABRAPSO vem congregando, incentivando e fundamentando para a construção de uma sociedade eticamente justa, economicamente equitativa, politicamente participativa, culturalmente plural, socialmente democrática e solidária

Safflower oil: an integrated assessment of phytochemistry, antiulcerogenic activity, and rodent and environmental toxicity

Gastric ulcers are a significant medical problem and the development of complications lead to significant mortality rates worldwide. In Brazil, Carthamus tinctorius L., Asteraceae, seeds essential oil, the safflower oil, is currently used as a thermogenic compound and as treatment for problems related to the cardiovascular system. In this study, by Raman spectroscopy, it was shown that oleic and linoleic acids are the compounds present in higher concentrations in the safflower oil. We demonstrated that safflower oil (750 mg/kg, p.o.) decrease the ulcerogenic lesions in mice after the administration of hydrochloric acid-ethanol. The gastric ulcers induced by non-steroidal anti-inflammatory drug (NSAID) in mice treated with cholinomimetics were treated with four different doses of safflower oil, of which, the dose of 187.5 mg/kg (p.o.) showed significant antiulcerogenic properties (**p < 0.01). Moreover, the safflower oil at doses of 187.5 mg/kg (i.d.) increased the pH levels, gastric volume (**p < 0.01) and gastric mucus production (***p < 0.001), and decreased the total gastric acid secretion (***p < 0.001). The acute toxicity tests showed that safflower oil (5.000 mg/kg, p.o.) had no effect on mortality or any other physiological parameter. Ecotoxicological tests performed using Daphnia similis showed an EC50 at 223.17 mg/l, and therefore safflower oil can be considered “non-toxic” based on the directive 93/67/EEC on risk assessment for new notified substances by European legislation. These results indicate that the antiulcer activity of Safflower oil may be due to cytoprotective effects, which serve as support for new scientific studies related to this pathology.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Santa Cecília Programa de Pós-graduação em Sustentabilidade de Ecossistemas Costeiros e Marinhos Laboratório de Pesquisa em Produtos NaturaisUniversidade Estadual de Campinas Departamento de Fisiologia e Biofísica Laboratório de Produtos NaturaisUniversidade Santa Cecília Laboratório de EcotoxicologiaUniversidade Federal de São Paulo (UNIFESP) Instituto do MarUniversidade Camilo Castelo Branco Instituto de Engenharia BiomédicaUNIFESP, Instituto do MarFAPESP: 2009/01788-5SciEL
