What works, and what really works.
In recent development discourse, much has been debated and written about evidence-based actions, defined as: ‘the application of the best available systematically assembled evidence in setting policy and practice’. Nutrition is clearly not exempt from justifying itself, and it is important that Public Health Nutrition has addressed this in recent issues. Much of our knowledge of ‘what works’ de...
متن کاملSynergies in the integration of energy net-works for electricity, gas, heating and cooling
Transformation of the energy sector to efficiency and climate protection The increasing demand for energy services in conjunction with extensive climate protection targets requires significant changes within the European energy sector. Consequently, a continuous transition from conventional and fossil fuelled power generation to low-carbon or even carbonfree generation is expected in the power ...
متن کاملWorks Title On the Ground State Energy of the Delta - Function Fermi Gas II : Further
Building on previous work of the authors, we here derive the weak coupling asymptotics to order γ2 of the ground state energy of the delta-function Fermi gas. We use a method that can be applied to a large class of finite convolution operators.
متن کاملA Study of the Concentrations of Polycyclic Aromatic Hydrocarbons in Gas Works Retort Houses.
Measurements of the concentration of 3:4-benzpyrene and other polycyclic aromatic hydrocarbons have been made in gas works retort houses of several types. The tarry fumes which escaped from retorts contained extremely high concentrations of polycyclic hydrocarbons, but in general men were only exposed to these very briefly. The mean concentration of 3 :4-benzpyrene determined from long-period s...

This paper provides empirical evidence for the Birch and Swinnerton-Dyer conjectures for modular Jacobians of genus 2 curves. The second of theseconjectures relates six quantities associated to a Jacobian over the rationalnumbers. One of these six quantities is the size of the Shafarevich-Tate group.Unable to compute that, we computed the five other quantities and solved for...
