Economic feasibility of algal biodiesel under alternative public policies
The motivation for this research was to determine the influence of public policies on economic feasibility of producing algal biodiesel in a system that produced all its energy needs internally. To achieve this, a steady-state mass balance/unit operation system was modeled first. Open raceway technology was assumed for the production of algal feedstock, and the residual biomass after oil extrac...
متن کاملNeonatal Sepsis among Neonates at Public Hospitals in Jimma, Ethiopia
Background Neonatal sepsis is one of the major causes of neonatal morbidity and mortality globally. Its incidence varies from 1 to 4 cases per 1,000 live births in developed countries. The burden of the problem occurs in the developing world while most confirmation is derived from developed countries. This study is aimed to assess the prevalence of neonatal sepsi...
متن کاملInsulin pumps.
I nsulin pump therapy—continuous subcutaneous insulin infusion (CSII)—was developed in the UK in the 1970s. Rapid technological developments changed the initial pumps from the size of a house brick, charged by mains electricity to an acceptable dimension, battery driven. We described the use of pumps in young people with type 1 diabetes (T1D) in the UK in Archives of Disease in Childhood in the...
متن کاملComparing pumps.
Comparative evolutionary studies have greatly aided our understanding of how the heart develops. Two recent articles from Benoit Bruneau’s laboratory reveal the power of the so-called evo-devo approach and provide yet further details of development, both of the heart itself and of the cells that build it. Thanks to our many and varied primitive cousins, developmental biologists are gaining a go...
متن کاملPeristaltic Pumps
Peristaltic pumps are mechanical displacement pumps that induce flow in a fluid-filled, flexiblewalled conduit through peristalsis – transport due to traveling contraction waves. While macroscale peristaltic pumps appear in a variety of configurations, micropumps based on this principle almost exclusively use the sequenced contraction and expansion of a small number of discrete actuators – typi...
