Optimal Reactive Power Planning Using Risk Analysis

In this paper, the optimal reactive power planning problem under risk is presented. The classical mixed-integer nonlinear model for reactive power planning is expanded into two stage stochastic model considering risk. This new model considers uncertainty on the demand load. The risk is quantified by a factor introduced into the objective function and is identified as the variance of the random variables. Finally numerical results illustrate the performance of the proposed model, that is applied to IEEE 30-bus test system to determine optimal amount and location for reactive power expansion.

Efeitos do Square Stepping Exercise nas capacidades funcionais e funções executivas em frequentadores do Centro do Idoso de Rio Claro - SP

With aging process, there is a natural biological decline that eventually may lead to a functional and cognitive decrease. It is important that older people preserve these functions so they can live an independent life. Some declines in old people who attend Geriatric Day-Care tend to be more severe and recurrent. The Square Stepping Exercise (SSE) is a program created by Shigematsu & Okura (2006), in order to improve the balance of its practitioners, thereby decreasing the risk of falls. It is also believed that the SSE stimulates cognition, and thus, executive functions. The present study, with a longitudinal design, evaluated the effects of SSE in balance performance and executive functions of elderly from the “Centro-Dia do Idoso Padre Casagrande” from Rio Claro – SP. A group of 15 people (GT, n = 15), which performed a four month SSE intervention, and a control group (GC; n = 17) answered the following evaluations.: Questionnaire Registration Data and Anamnesis, Questionnaire Baeck Modified for Elderly, Mini-Mental State Examination, Modified Card Sorting Test, Geriatric Depressive Scale, Questionnaire Pfeffer for Instrumental Activities, Berg Balance Scale and Time Up and Go Test. Although significant improvements have not been observed in GT, the results showed a decline in instrumental activities performance in GC, as well as maintenance in executive functions and balance, and also an improvement in depressive symptoms in GT. This way, Square Stepping Exercise can be considered an activity that helps maintaining functional capacity, among them balance, and executive function in elderly people.

Square stepping exercise: uma revisão

Many studies inform that with aging process there’s a drop, not only in the cognitive functions, but also in the functional fitness. This drop can damage the old people’s daily activities, making them lose their independence. These declines can be softened with the practice of physical exercises. So, the aim of this study is to develop a systematic review in the literature which is the quantity of lectures done using the Square Stepping Exercise, we use a follow keyword “Square Stepping Exercise”. We performed a search in the following databases: PUBMED, Portal de Periódicos CAPES, Google Acadêmico e Catálogo Athena (acervo da Biblioteca de todos os campus da UNESP). Those procedures were complemented for manual searches in the references of the found lectures, like the access to the curriculum vitae, plataforma Lattes. There were analyzed articles, in Portuguese and English. Language were selected 11 studies (2 monografies, 1 masters lecture, 1 experience relatorie, 1 book chapter and 6 articles). The references found had improvement in motor and cognitive aspects. With this review, it was concluded that the SSE showed itself as a useful method to get better and/or maintain the analyzed aspects. It’s also necessary new studies with different populations, tips of analyse, periods of time and other aspects

Preliminary in vitro and ex vivo evaluation of afzelin, kaempferitrin and pterogynoside action over free radicals and reactive oxygen species

Biological activities of flavonoids have been extensively reviewed in literature. The biochemical profile of afzelin, kaempferitrin, and pterogynoside acting on reactive oxygen species was investigated in this paper. The flavonoids were able to act as scavengers of the superoxide anion, hypochlorous acid and taurine chloramine. Although flavonoids are naturally occurring substances in plants which antioxidant activities have been widely advertised as beneficial, afzelin, kaempferitrin, and pterogynoside were able to promote cytotoxic effect. In red blood cells this toxicity was enhanced, depending on flavonoids concentration, in the presence of hypochlorous acid, but reduced in the presence of 2,20 -azo-bis(2-amidinopropane) free radical. These flavonoids had also promoted the death of neutrophils, which was exacerbated when the oxidative burst was initiated by phorbol miristate acetate. Therefore, despite their well-known scavenging action toward free radicals and oxidants, these compounds could be very harmful to living organisms through their action over erythrocytes and neutrophils.
