Transmission network expansion planning considering multiple generation scenarios

This paper presents a mathematical model and a methodology to solve a transmission network expansion planning problem considering open access. The methodology finds the optimal transmission network expansion plan that allows the power system to operate adequately in an environment with multiples generation scenarios. The model presented is solved using a specialized genetic algorithm. The methodology is tested in a system from the literature. ©2008 IEEE.

Perfil materno e dos recém-nascidos nascidos vivos na primeira década do século XXI em município do interior paulista com ênfase na prematuridade

The concern with infant mortality has been a priority in public policies, especially for Brazil to achieve the Millennium Development Goal number four: reducing child mortality by 75% by the year 2015. It is known that prematurity has an intimate relationship with mortality of children under one year and therefore it is necessary an effective intervention in risk factors linked to premature births. To evaluate the profile of mothers and newborn babies living in Botucatu-SP, in the period 2001 to 2009, focusing on prematurity. A quantitative study, retrospective, descriptive, epidemiological, from the Information System Newborn Alive. The prevalence of preterm births was 15.1%, and low birth weight 14.7%. Among infants, the Apgar score below 7 at 1 and at 5 minutes was 13.1% and 2.4% respectively. Considering the total of pregnant women studied, 20.3% were adolescents and 10.3% were aged 35 years or more and most (63.2%) had eight or more years of school approval. The profile of mothers of premature infants shows that 23.6% were teenagers, 14.1% had at least 35 years and 60.4% had at least primary education. With regard to premature deliveries, caesarean sections and 58.4% were between the total newborns, this type of delivery was achieved in 46.6% of cases. Prematurity was associated with an Apgar score below seven in the first and fifth minutes of life, presence of malformation and multiple pregnancy. Among maternal variables, prematurity was associated with extremes of maternal age, maternal education, history of stillbirth, primiparas, white and presence of the mother's partner. With regard to delivery was associated with cesarean section and outside the hospital. This study assessed maternal characteristics associated with prematurity and point out how relevant the pregnancies at the extremes of age and those that occur in women with low education level, indicating the interference...
