Bio-oils derived from waste wood resources are thought to be potential alternatives for petroleum asphalt binders used in asphalt pavement. This study aims to evaluate the effect of bio-oils on asphalt mixture performance after blending bio-oil (5% and 10% by weight, respectively) into the traditional asphalt binder. Three types of bio-oils are used - the original bio-oil (OB), dewatered bio-oil (DWB) and polymer-modified bio-oil (PMB). The asphalt pavement analyzer (APA) test, four-point beam fatigue test, dynamic modulus (|E â̂ -|) test and indirect tensile (IDT) strength test were conducted to evaluate the rutting resistance, fatigue performance, dynamic stiffness, and tensile strength, respectively. The test results showed that the addition of bio-oils significantly improves the asphalt mixture fatigue performance, has no significant effect on the rutting performance and dynamic modulus, but slightly impacted the tensile strength. In addition, polymer in the bio-oil was observed to improve the asphalt mixture performance as the PMB modified asphalt mixtures performed better than the two other mixtures. Further, statistical analysis on the laboratory test results are conducted and found to be consistent with the findings above. The study shows that the bio-oils derived from waste wood resources can be a good extender and modifier for petroleum asphalt binders in the pavement industry. © 2013 Elsevier Ltd.

We establish a unified approach to stability analysis for switched linear descriptor systems under arbitrary switching in both continuous-time and discrete-time domains. The approach is based on common quadratic Lyapunov functions incorporated with linear matrix inequalities (LMIs). We show that if there is a common quadratic Lyapunov function for the stability of all subsystems, then the switched system is stable under arbitrary switching. The analysis results are natural extensions of the existing results for switched linear state space systems.

Despite medical advances in technology, improved socioeconomics, and medical knowledge, an estimated 55,000 children die every year in the United States. A phenomenological study was conducted at a tertiary-quaternary children's hospital to determine the emerging patterns amidst the chaos with nurses caring for children dying unexpectedly. Implications for nursing practice include a progression of caring, a set of patterns that emerge out of the seeming chaos of a coding patient. These patterns shed light on the interactive relationships within the hospital and can foster collaboration among bedside nurses, advanced practice nurses, inter-professional team members, directors, and hospital administrators. © 2014 Elsevier Inc.

This paper develops seismic demand models for multi-story buildings. Story-specific demand models that consider the maximum interstory drift of each story are developed. Correlations among individual story demand models are also assessed to properly capture the potential dependence between maximum interstory drifts over the height of a building. Both linear and bilinear models in logarithmic space are considered to describe the relationships between drift demand and seismic intensity. A Bayesian approach is used to estimate the model parameters. The developed demand models are used to estimate the seismic fragility of two example buildings. The fragility estimates are compared with currently available estimates based on demand models for the overall maximum interstory drift. It is shown that when only the maximum interstory drift of a building is considered, the fragility might be underestimated; particularly if the interstory drifts for one or more stories are close to the maximum value. The proposed methodology provides a refined approach that includes more building response information than typical demand models, allowing for more accurate estimates of the seismic fragility of multi-story buildings. © 2010 Elsevier Ltd.

Background: Although direct nose-to-brain drug delivery has multiple advantages, its application is limited by the extremely low delivery efficiency (1%) to the olfactory region where drugs can enter the brain. It is crucial to developing new methods that can deliver drug particles more effectively to the olfactory region. Materials and methods: We introduced a delivery method that used magnetophoresis to improve olfactory delivery efficiency. The performance of the proposed method was assessed numerically in an image-based human nose model. Influences of the magnet layout, magnet strength, drug-release position, and particle diameter on the olfactory dosage were examined. Results and discussion: Results showed that particle diameter was a critical factor in controlling the motion of nasally inhaled ferromagnetic drug particles. The optimal particle size was found to be approximately 15 μm for effective magnetophoretic guidance while avoiding loss of particles to the walls in the anterior nose. Olfactory delivery efficiency was shown to be sensitive to the position and strength of magnets and the release position of drug particles. The results of this study showed that clinically significant olfactory doses (up to 45%) were feasible using the optimal combination of magnet layout, selective drug release, and microsphere-carrier diameter. A 64-fold-higher delivery of dosage was predicted in the magnetized nose compared to the control case, which did not have a magnetic field. However, the sensitivity of olfactory dosage to operating conditions and the unstable nature of magnetophoresis make controlled guidance of nasally inhaled aerosols still highly challenging. © 2015 Xi et al.
