Breast micro-opacities of lead origin mimicking microcalcifications

After a surgical excision of focal mammary "microcalcification" we noticed that in fact they represented fine lead deposits (mean diameter: 100 microns) resulting from an attempted suicide (22 long rifle) 10 years previously. The leaded nature of these foreign microbodies was demonstrated by a micro-analysis by energy dispersion on histological slides.     

Nuclear data sheets for A = 78

The 1966 version of Nuclear Data Sheets for A = 78 has been revised on the basis of all experimental data received before September 1, 1974. Experimental data, detailed level schemes, and arguments for J^π-assignments are presented. Two new isotopes, ⁷⁸Ga and ⁷⁸Rb, are now known to exist and a third, ⁷⁸Sr, has been tentatively identified. A significant amount of new information is given for the ⁷⁸Se, ⁷⁸Br, and ⁷⁸Kr level schemes, while very little new information is available for the level schemes of ⁷⁸Ge and ⁷⁸As.     

Modelling and performance comparison of optimal AIGaAs/GaAs DMTs and multichannel HEMTs for power amplification

We present two detailed studies concerning thedmt and the multichannelhemt for power amplifications. Each work comprises a first theoretical part where the structure is optimized by simulating the device. Technological realizations are hence performed at the laboratory. The following measurements give results very encouraging and permit to foresee the superior performance relatively to that of GaAs powermesfet.     

A Bayesian analysis of experiments with small numbers of events

Within the framework of Bayesian statistics we derive a distribution for the posterior degree of belief both for the difference and ratio of small numbers of events, when the background mean in each case is known with finite precision.

Cross sectoral and scale-up impacts of greywater recycling technologies on catchment hydrological flows.

With the growth of urban areas and climate change, decisions need to be taken to improve water management. This paper reports an assessment of the impact of greywater recycling systems on catchment scale hydrological flows. A simulation model developed in InfoWorks CS (Wallingford Software Ltd) was used to evaluate how river flows, sewer flows, surface runoff and flooding events may be influenced when grey water recycling systems of different number and scale are implemented in a representative catchment. The simulations show the effectiveness of greywater recycling systems in reducing total wastewater volume and flood volume. However, no hydraulic impacts due to implementation of greywater was identified by the model.     

MRI study of bread baking: experimental device and MRI signal analysis

An oven dedicated to a magnetic resonance imager (MRI) was designed and constructed for continuous monitoring of the entire baking process. The general aim was to test whether response variables conventionally measured on bread loaves, such as temperature, density, and water loss, were consistent with those reported for similar products baked in classical convection ovens. MRI images acquired during baking are presented and discussed, emphasising the need to develop quantitative MRI methods allowing conversion of the MRI signal into one variable of interest, such as local density or local water content.     

A Strategic Approach for Managing Oil and Gas Assets

The global oil market is experiencing a structural shift. Faced with a rapid price decline, large oil-producing countries had decided to protect their market share, with the hopes of permanently removing expensive supply from the market. Meanwhile, the ability of the US shale oil producers to respond quickly to positive price signals puts downward pressure on prices. On the demand side, advances in renewable technology and the continued effort to curb consumption of fossil fuel conspire to inhibit long-run growth.¹ These factors suggest that the current down-cycle may continue for an extended period of time or even invoke another down-cycle.     

Experimental characterization of the chaotic dynamics of cohesionless particles: application to a V-blender

So far, most of the investigations of the dynamics of granular material in blenders have been done in 2D tumblers due to the current lack of accurate measurement methods for the investigation of complex 3D flows. However, recent advances in the field of non-intrusive methods have paved the way to the characterization of the chaotic dynamics in 3D blenders. This work aims to present such an analysis in the case of a V-blender using radioactive particle tracking (RPT). Special attention is given to the chaotic properties of mixing by performing a time-series analysis of the position of a single tracer in motion in this blender. An original investigation of the mixing properties is also presented. More generally, this work shows that the mixing properties of a blender can be characterized by using tools of dynamical systems theory through a time-series analysis of data obtained from non-intrusive measurements.
