200 år sedan slaget vid Waterloo. Andrew Roberts har skrivit en modern och dramatisk skildring av det berömda fältslaget! Det är försommar år 1815. 200 000 soldater har samlats i trakterna kring byn Waterloo i Belgien för att avgöra Europas öde. Napoleon är segerviss trots motståndarnas numerära övertag; hans taktik är att hålla den preussiska armén och deras allierade åtskilda för att kunna besegra dem var för sig. Men Napoleon får snart känna på bakslag. Ett kraftigt skyfall förvandlar slagfältet till en lervälling vilket komplicerar hans framryckning. Lägg därtill ett antal mänskliga misstag och Napoleon får anledning att oroas; en oerfaren stabschef, ett oavsiktligt kavallerianfall och ett otal snabba, ogenomtänkta beslut. På kvällen den 18 juni 1815 sänder Napoleon ut sin sista reserv u001a det hittills obesegrade kejserliga gardet. Några timmar senare flyr han hals över huvud från sitt högkvarter La Belle Alliance. Historikern och författaren Andrew Roberts har utifrån ny forskning kartlagt det dramatiska slaget vid Waterloo. Hans initierade skildring ger oss en politisk, strategisk och historisk bakgrund till fältslaget, och visar varför det utgör en så viktig historisk skiljelinje.

Gasoline compression ignition (GCI) combustion is a promising solution to address increasingly stringent efficiency and emissions regulations imposed on the internal combustion engine. However, the high resistance to auto-ignition of modern market gasoline makes low load compression ignition operation difficult. The most comprehensive work focused on low load GCI operation has been performed on multi-cylinder research engines where it is difficult to decouple effects of the combustion event from air-handling and system level parameters (e.g., intake pressurization and exhaust gas recirculation (EGR)). Further, most research has focused on technology applications (e.g., use of variable valve actuation or supercharging) rather than fundamental effects, making identification of influential factors difficult. Accordingly, there is a need for detailed investigations focused on isolating the critical parameters that can be used to enable low load GCI operation. A full factorial parametric study was completed to isolate the effects of intake temperature, EGR rate, and fuel reactivity on low load performance. A minimum intake pressure metric was used to compare these parameters. This allowed combustion phasing and load to be held constant while isolating the experiment from fuel injection effects. The effort showed that increasing intake temperature yields a linear reduction in the minimum intake pressure required for stable operation. Adding a small amount of diesel fuel to gasoline improved combustion stability with minimal need for energy addition through intake pressurization. The minimum intake pressure requirement also showed very good correlation with the measured research octane number of the fuel. However, increasing the fuel reactivity with diesel fuel, caused NOx emissions to increase. Response model analysis was used to determine the intake conditions required to maintain NOx levels that may not require lean NOx after treatment. The combination of diesel fuel blending and EGR allowed NOx levels to be reduced to near zero values with the minimum intake pressurization required. A detailed investigation into the effects of EGR showed that, for a given fuel, there is a maximum EGR rate that allows for stable operation, which effectively constrains the minimum NOx prior to aftertreatment. Accordingly, a method that enables the variation of the fuel reactivity on demand is an ideal solution to address low load stability issues. Metal engine experiments conducted on a single cylinder medium-duty research engine allowed for the investigation of this strategy. The fuels used for this study were 87 octane gasoline (primary fuel stream) and diesel fuel (reactivity enhancer). Initial tests demonstrated load extension down to idle conditions with only 20% diesel by mass, which reduced to 0% at loads above 3 bar indicated mean effective pressure (IMEPg). Engine performance over a mode weighted drive cycle was completed based on work by the Ad-Hoc fuels committee [1] to demonstrate the performance of various levels of fuel blending for five primary modes of operation encompassing low load to high load. Lastly, several simulated transient drive cycle were analyzed to investigate the consumption rate of the reactivity enhancer. A response model was fit to the experimental data and exercised over the load based drive cycle. Results showed that the diesel consumption could be reduced to additive levels over a 10k mile oil change interval, lower than typical diesel exhaust fluid (DEF) consumption levels, which presents a pathway to a full-time GCI engine. Experimental efforts used a minimum intake pressure metric to evaluate the auto-ignition quality of seven fuels, including two pump fuels and five FACE gasolines in a GCI engine. The results showed that research octane number (RON) trends well with the intake pressure required to achieve a desired ignition delay at low-temperature conditions, which are representative of a boosted GCI engine. At higher temperature intake conditions poor correlation is observed between RON and intake pressure requirement. Effects of octane sensitivity were dominated by the general reactivity of fuel as characterized by RON. The Octane Index and K-factors were regressed for each operating condition, and good correlation was seen between the Octane Index and the intake pressure requirement. Main effects analysis of the impact of general properties of the fuel (RON, motor octane number (MON), and sensitivity (S)) on the intake pressure requirement showed that RON was the only statistically significant parameter. Analysis of the main effects of fuel composition on intake pressure requirement showed some trends, but none were statistically significant. This indicates that the auto-ignition quality of the fuel is not characterized by variations in any single species. Analysis of the stable start-of-injection (SOI) timing injection window showed that both RON and sensitivity describe stability at low temperatures. In general, a fuel with a higher RON will have a smaller stable SOI window than a lower RON fuel. Additionally, fuels with the same RON and different sensitivities will behave differently. Analysis showed that, for a given RON, a low sensitivity fuel would tend to have a wider operating window than a high sensitivity fuel. Analysis of the heat release for the experimental cases showed that this is due to the presence of low-temperature chemistry. Fuels that suppress low-temperature chemistry did not show low-temperature heat release (LTHR) and had a narrower stability window. At high temperatures, LTHR was suppressed for all fuels, as the temperature in the jet exceeded the ceiling temperature for low-temperature oxidation.

The aorta is an integral component of the cardiovascular system, damping pressure fluctuations, and determining the systemic pressure and afterload on the heart left ventricle. Arteries, especially the aorta, stiffen with age and disease which alters this dynamic relationship. Increased aortic stiffness has been associated with risk of cardiovascular events. The cardiovascular system can be evaluated by Magnetic Resonance Imaging (MRI) which provides detailed anatomical and functional information. Exercise stress testing is also an essential clinical tool to evaluate cardiovascular function. Cardiovascular changes induced by the additional metabolic demand under exercise, together with the exercise capacity and symptomatic responses provide clinicians with diagnostic and prognostic information that can aid clinical decision making. Combining MR imaging with exercise testing is difficult to achieve due to the high magnetic fields inherent to MRI environments and their susceptibility to interference from external electronic signals. An exercise bicycle compatible with the MRI environment has been developed which enables subjects to exercise lying inside the scanner, allowing images to be acquired immediately after an appropriate exercise capacity is achieved. Imaging procedures to evaluate left ventricular function were optimised to accommodate the elevated heart rates associated with moderate exercise. Additionally, two imaging methods estimating aortic stiffness were implemented and validated against aortic phantoms. Incorporated into a pump system developed specifically for validation, pulsatile aortic blood flow was simulated through these compliant phantoms. These methods were applied to patients with aortic disease at rest and during moderate exercise. The efficacy of two treatments for hypertension was assessed in patients with aortic regurgitation, ascending aortic aneurysms, abdominal aortic aneurysms, Marfan syndrome and repaired coarctation of the aorta. A group of healthy subjects were also evaluated as controls. The methods developed in this thesis enable better assessment of the effectiveness of current treatment methods and will further improve our understanding of cardiovascular disease processes.

La biographie croisée de deux géants que tout oppose. Si Andrew Roberts est désormais bien connu du public francophone grâce au succès de son Churchill paru en traduction en 2020, il se penche de longue date sur la personnalité, la carrière et l''oeuvre du grand homme. Ici, l''auteur enfourche l''un de ses chevaux de bataille préférés pour s''en prendre à ceux qui suggèrent qu''au fond, il n''y avait guère de différence entre Hitler et Churchill. Leur expérience des tranchées au cours de la Grande Guerre, leur patriotisme exacerbé, la fierté qu''ils tiraient du glorieux passé de leur pays et par-dessus tout leur charisme, leur art de mener les hommes, le pouvoir psychologique qu''ils exerçaient sur les foules - et ce, souvent même en dehors de leur patrie : tout cela, lit-on çà et là, les rapprochait au point de faire d''eux des frères ennemis. Andrew Roberts montre magnifiquement le caractère fallacieux de ces points communs supposés, et d''abord sur le plan pratique, en rappelant que Churchill a toujours su déléguer le pouvoir de décision militaire à ses chefs d''état-major en se rendant à leurs arguments - certes, non sans avoir au préalable ferraillé avec eux jusqu''au bout - tout en se réservant le rôle de représentant indiscuté du Royaume-Uni auprès de ses interlocuteurs Roosevelt et Staline. Cette délégation de pouvoir, Hitler l''a certes appliquée lors des grands triomphes de la guerre éclair, en Pologne et en France, en 1939-1940, mais il y a mis fin dès les premiers revers sur le front soviétique à la fin de 1941, pour devenir totalement incapable de faire confiance à ses généraux après l''attentat de juillet 1944. Pour l''auteur, un grand meneur d''hommes c''est un chef qui, au contraire, pratique la confiance à double sens : le commandant en chef fait confiance aux commandants sur le terrain dont il a su discerner la compétence en les nommant, et les subordonnés, aussi hauts gradés qu''ils soient, lui font confiance pour les soutenir sans réserve une fois qu''ils l''ont amené à percevoir le bien-fondé de leurs entreprises. Ce fut là, soutient Andrew Roberts dans des pages fort convaincantes, ce qui fit la force de Churchill, chef de guerre de 1940 à 1945.
