This study examines the effects of nano-size particulate matter (nPM) exposure in the setting of murine reperfused stroke. Particulate matter is a potent source of inflammation and oxidative stress. These processes are known to influence stroke progression through recruitment of marginally viable penumbral tissue into the ischemic core. nPM was collected in an urban area in central Los Angeles,...

You have 3 hours and you have to answer 12 questions. Answer 9 out of questions 1–12, and you have to answer questions 13 – 15. Mark clearly which three questions are not to be graded. Each one of the first 9 questions is worth 18 points and the last three 12 points each (total of 200). You may use two sheets of paper freely written on four sides. Please attach them to the exam. Show full logic...

Airborne particulate matter has become an important topic of epidemiological and environmental studies in the last decade when it was understood that the particulate matter is an important determinant of deaths, especially in the elderly, even though the biological mechanisms of its effect are not quite clear yet. The United States Environmental Protection Agency regulates the admissible levels...

Leadership is a key factor impacting construction safety, but previous research merely investigated the single-level relationship between safety leadership and safety performance and ignored the leadership interaction between different project stakeholders. To fill this gap, this paper aims to examine the relationships between safety leaderships of project owners, contractors and subcontractors...

Research on the SAT has shown a substantial correlation with measures of g such as the Armed Services Vocational Aptitude Battery (ASVAB). Another widely administered test for college admission is the American College Test (ACT). Using the National Longitudinal Survey of Youth 1979, measures of g were derived from the ASVAB and correlated with ACT scores for 1075 participants. The resulting cor...

Although learning from projects has gained much importance in research and practice, progress in understanding and improving inter-project learning appears to be slight. We argue that the adoption of a sender/receiver approach limits the learning effectiveness in project-based organisations. Drawing upon the notion of learning as a social activity embedded in an organisational context, we devel...

Coastal remote sensing applications are regularly confined to single image ‘snapshot’ approaches which do not resolve the dynamic processes in the required temporal resolution. This paper reports the results of a project in which the dynamics of tidal sedimentation were monitored by multi-temporal airborne remote sensing in 10 minute time steps. The radiance data was then converted to estimates...

We have found that the two-point correlation function of the APM clusters of galaxies has an amplitude much higher than that claimed by the APM group. As the richness limit increases from R = 53 to 80, the correlation length increases from 17.5 to 28.9 hMpc. This indicates that the richness dependence of the APM cluster correlation function is also much stronger than what the APM group has repo...
