Data registration and integration requirements for severe storms research

Severe storms research is characterized by temporal scales ranging from minutes (for thunderstorms and tornadoes) to hours (for hurricanes and extra-tropical cyclones). Spatial scales range from tens to hundreds of kilometers. Sources of observational data include a variety of ground based and satellite systems. Requirements for registration and intercomparison of data from these various sources are examined and the potential for operational forecasting application of techniques resulting from the research is discussed. The sensor characteristics and processing procedures relating to the overlay and integrated analysis of satellite and surface observations for severe storms research are reviewed

Why is Polygyny More Prevalent in Western Africa?: An African Slave Trade Perspective

Polygyny rates are higher in Western Africa than in Eastern Africa. The African slave trades explain this difference. More male slaves were exported in the trans-Atlantic slave trades from Western Africa, while more female slaves were exported in the Indian Ocean and Red Sea slave trades from Eastern Africa. The slave trades led to prolonged periods of abnormal sex ratios, which impacted the rates of polygyny across Africa. In order to assess these claims, we construct a unique ethnicity-level data set linking current rates of polygyny with historical trade flow data from the African slave trades. Our OLS estimates show a positive correlation between the trans-Atlantic slave trades and polygyny. An IV approach shows the relationship is causal and statistically signicant. We also provide cross-country evidence corroborating our findings.slave trades; polygyny; Africa; development

A pressure drop investigation of immiscible liquid-liquid micro flows

This paper was presented at the 2nd Micro and Nano Flows Conference (MNF2009), which was held at Brunel University, West London, UK. The conference was organised by Brunel University and supported by the Institution of Mechanical Engineers, IPEM, the Italian Union of Thermofluid dynamics, the Process Intensification Network, HEXAG - the Heat Exchange Action Group and the Institute of Mathematics and its Applications.Over the past decade there has been a considerable increase in the research on lab-on-a-chip applications that focuses on designing analytical chemical and biological devices. One such application is the possibility of integrating the functional steps of DNA analysis into a micro-total-analysis system (μTAS). Encapsulation of PCR samples within an inert carrier fluid allows the samples to be transported as micro-reactors. Plug based micro reactors suspended in an inert carrier fluid have a lot of promise in microfluidic analytical devices, offering a reduction in resident-time, reagents and labour with an increase in through-put, accuracy and quality. The development of a thin wetting film between the wall of the capillary and the micro reactor increase the interfacial area of the plug and can also intensify the internal circulation occurring within the plug. Only recently has work being preformed on the fluid mechanics that characterise this scale. An experimental study is carried out to study the effect capillary diameter, carrier viscosity and flow rate has on the pressure drop under bi-phasic flow conditions
