171   Maternal Mortality in Jamaica: Socioeconomic Factors Maternal Mortality in Jamaica: Socioeconomic Factors Rebecca Jean Emigh    2011 Socioeconomic factors relating to all maternal deaths identified during the 12 months of the Jamaican Perinatal Morbidity and Mortality Survey were compared with a control population of over 10,000 women. The maternal mortality rate was 11.5 per 10,000 livebirths. Initial analyses revealed (a) that the risk of maternal death declined with increasing maternal education level, (b) that mothers who lived in households with direct pumped water and/or flush toilets enjoyed a reduced risk; (c) mothers... 查看全文

172   Executive Function Predicts Adaptive Behavior. in Children with Histories of Heavy Prenatal Alcohol Exposure and Attention-Deficit/Hyperactivity Disorder Executive Function Predicts Adaptive Behavior. in Children with Histories of Heavy Prenatal Alcohol Exposure and Attention-Deficit/Hyperactivity Disorder Ailsa Cameron and Abigail Masterson    2012 Prenatal exposure to alcohol often results in disruption to discrete cognitive and behavioral domains, including executive function (EF) and adaptive functioning. In the current study, the relation between these 2 domains was examined in children with histories of heavy prenatal alcohol exposure, nonexposed children with a diagnosis of attention-deficit/hyperactivity disorder (ADHD), and typically developing controls. 查看全文

175   Terrorism: Limits Between Crime and War. The Fallacy of the Slogan ‘War on Terror’ Terrorism: Limits Between Crime and War. The Fallacy of the Slogan ‘War on Terror’ Mariona Llobet    0 This chapter illustrates that a key challenge in contemporary discourses on this subject lies in identifying the limits between terrorism and war. It makes clear that there appears to be considerable confusion between the concept of terrorism and the concept of war in the post 9/11 era, especially in the context of military action in Iraq and Afghanistan. The link between terrorism and war is analysed from three distinct but interrelated perspectives. Firstly, te... 查看全文

176   Nano-scale tribological properties of silicon pillars with the variation in pitch Nano-scale tribological properties of silicon pillars with the variation in pitch    2009 Topographical modification of silicon (100) wafers was performed by the creation of nano-structures that consists of pillars with different pitch. The modified surfaces were investigated for their tribological characteristics at nano-scale in comparison with those of the bare silicon surface. Results showed that the modified surfaces have superior nano-tribological properties, as they reduce adhesion and friction forces significantly when compared to the bare silicon surface. Among the nano-stru... 查看全文

178   Influence of alkyl side chains on hydrogen-bonded molecular surface nanostructures Influence of alkyl side chains on hydrogen-bonded molecular surface nanostructures    2008 A study was conducted to demonstrate the systematic comparison of adsorption structures formed from a class of compounds that all display the same types of strong hydrogen-bonding groups. The study used high-resolution scanning tunneling microscopy (STM) imaging under ultrahigh-vacuum (UHV) conditions for the systematic comparison. The observed structures all appear to be dominated by the anticipated hydrogen-bonding interactions, but the study found that subtle changes to a side group not direc... 查看全文

In particular, heterocycles in a hexagonal ordering exhibit the lowest energy configuration for the CNNts studied. Overall, heptazine-based CNNts are energetically preferred over triazine motifs. Correspondingly, recent experimental data show the prevalence of heptazine units in synthesized CNNts. Nitrogen-ni... 查看全文

184   On the application of Particle Swarm Optimization strategies on Scholte-wave inversion On the application of Particle Swarm Optimization strategies on Scholte-wave inversion Marco Pilz, Stefano Parolai, Matteo Picozzi and Dino Bindi    2012 We investigate different aspects concerning the application of swarm intelligence optimization to the inversion of Scholte-wave phase-slowness frequency (p–f) spectra with respect to shear wave velocity structure. Besides human influence due to the dependence on a priori information for starting models and interpretation of p–f spectra as well as noise, the model resolution of the inversion problem is strongly influenced by the multimodality of the misfit function. We thus tested the... 查看全文
