Ebola virus infection is a severe infectious disease with the highest case fatality rate which become the global public health treat now. What makes the disease the worst of all is no specific effective treatment available, its dynamics is not much researched and understood. In this article a new mathematical model incorporating both vaccination and quarantine to study the dynamics of Ebola epidemic has been developed and comprehensively analyzed. The existence as well as uniqueness of the solution to the model is also verified and the basic reproduction number is calculated.
Carbon capture and storage (CCS) technologies are being developed to comply with the intensification of environmental laws and policies. Techniques for carbon capture from exhaust gases include post-combustion, pre-combustion and oxy-combustion. CO2 separation in gas processing is also a relevant application, employing alternatives commonly used in post-combustion, sharing developments and pulling innovations (additional to innovations pushed by knowledge from basic and applied research).
Background Soil-transmitted helminth infections are a major global health issue, causing substantial morbidity in the world's poorest populations. Regular delivery of anthelmintic drugs is the mainstay for global soil-transmitted helminth control. Deworming campaigns are often targeted to school-aged children, who are at high risk of soil-transmitted-helminth-associated morbidity. However, findings from modelling studies suggest that deworming campaigns should be expanded community-wide for effective control of soil-transmitted helminth transmission.
First-best climate policy is a uniform carbon tax which gradually rises over time. Civil servants have complicated climate policy to expand bureaucracies, politicians to create rents. Environmentalists have exaggerated climate change to gain influence, other activists have joined the climate bandwagon. Opponents to climate policy have attacked the weaknesses in climate research. The climate debate is convoluted and polarized as a result, and climate policy complex.
An international review of stormwater regulation and practices, especially for low-exposure, landscape irrigation schemes in urban environments, was undertaken with a view to identifying what could be used in Alberta, Canada. A general lack of clear guidance and regulation to manage stormwater quality and potential public health risks was identified, which could be hindering the uptake of stormwater schemes generally.
An effective response to climate change demands rapid replacement of fossil carbon energy sources. This must occur concurrently with an ongoing rise in total global energy consumption. While many modelled scenarios have been published claiming to show that a 100% renewable electricity system is achievable, there is no empirical or historical evidence that demonstrates that such systems are in fact feasible. Of the studies published to date, 24 have forecast regional, national or global energy requirements at sufficient detail to be considered potentially credible.
