nowhere are the barriers to a functional health infrastructure more clearly on display than in the goma region of democratic republic of congo. kaboru et al. report poorly integrated services for hiv and tb in this war-torn region. priorities in conflict zones include provision of security, shelter, food, clean water and prevention of sexual violence. in goma, immediate health priorities includ...

Mass media regularly feeds on the Transportation Security Administration (TSA)’s checkered past, and for good reason. According to a recent ABC News exclusive, “an internal investigation of the Transportation Security Administration revealed security failures at dozens of the nation’s busiest airports, where undercover investigators were able to smuggle mock explosives or banned weapons through...

This article offers an ethnographic exploration of NGO “mission creep” as a result obtaining funding. Many scholars express scepticism about funding on goals, while others encourage nuanced critique. 18-month study two NGOs in Bangalore, India explores workers navigating the acceptance maintaining their original missions. When one failed to uphold this goal, staff members created own NGO. Findi...

Having decided to focus attention on the “weak link” of human fallibility, a growing number of security researchers are discovering the US Government’s regulations that govern human subject research. This paper discusses those regulations, their application to research on security and usability, and presents strategies for negotiating the Institutional Review Board (IRB) approval process. It ar...

Abstract Dynamic covalent polymer networks provide an interesting solution to the challenging recyclability of thermosets and elastomers. One remaining design constraints, however, is balancing thermal reprocessability in form material flow with dimensional stability during use. As a result, many chemistries are being investigated order improve bond reactivity control robustness. This Minirevie...

the creep/recovery behavior of wood flour-polypropylene was compared with medium density fiberboard (mdf) and particleboard. for this purpose, wood flour-polypropylene composites (with and without compatibilizer)were manufactured by using a laboratory twin-screw extruder. the mdf and particleboard panels were obtained from local producers. short term flexural creep tests at 30% of ultimate bend...

the effect of impact modifier on creep behavior of wood flour- recycled polypropylene composites has been evaluated in this work. for this purpose, impact modifier (ethylene vinyl acetate) and recycled polypropylene were mixed with wood flour (50/50% w/w) as well as the impact modifier (0, 3%, 6% and 9%) by a counter-rotating twin-screw extruder to manufacture the wood flour- recycled polypropy...

Background: The short-time creep behavior for a series of biodegradable nanocomposites which is used as implantable device into body is a crucial factor. In the current paper, we aimed to study the effect of bioactive glass nanoparticles (BGn) on creep and creep-recovery behaviors of PLA/PCL blends at different given load and different applied temperatures. Method: A series of biodegradab...
