Combining in-cylinder pressure and 1D simulation tools to understand the combustion characteristics of natural gas in pre-chamber ignition systems for energy generation
Recent outlooks suggest a long-term relevance of internal combustion engines for both power generation and transportation. Nonetheless, stringent pollutant reduction requirements combined with new CO2 mandates draws a challenging scenario, requiring intensive research and development activities to develop and optimize combustion modes to fulfill these requirements. Among the recent advancements, t
Deep learning for rapid and reproducible histology scoring of lung injury in a porcine model
Acute respiratory distress syndrome (ARDS) is a life-threatening condition with mortality rates between 30-50%. Although in vitro models replicate some aspects of ARDS, small and large animal models remain the primary research tools due to the multifactorial nature of the disease. When using these animal models, histology serves as the gold standard method to confirm lung injury and exclude other
A 3D-CFD Methodology for Combustion Modeling in Active Prechamber SI Engines Operating with Natural Gas
Active prechamber combustion systems for SI engines represent a feasible and effective solution in reducing fuel consumption and pollutant emissions for both marine and ground heavy-duty engines. However, reliable and low-cost numerical approaches need to be developed to support and speed-up their industrial design considering their geometry complexity and the involved multiple flow length scales.
The genomic natural history of the aurochs
Now extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1. Here we analysed 38 ancient genomes and found 4 distinct population ancestries in the aurochs—European, Southwest Asian, North Asian and South Asian—each of whic
Effect of Pre-Chamber Volume and Nozzle Diameter on Pre-Chamber Ignition in Heavy Duty Natural Gas Engines
It has previously been shown by the authors that the pre-chamber ignition technique operating with fuel-rich pre-chamber combustion strategy is a very effective means of extending the lean limit of combustion with excess air in heavy duty natural gas engines in order to improve indicated efficiency and reduce emissions. This article presents a study of the influence of pre-chamber volume and nozzl
On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex
Popular Abstract in Swedish Evolusjon og energikonservering i en katalysator i cellens kraftverk Alle levende organismer må omforme energien i mat eller sollys til en form som cellen kan bruke som energi. Energien brukes både til prosesser som bryter ned og bygger opp komponenter i cellen. Den brukes også til prosesser som muskelsammentrekninger, celledelinger og bevegelser. Uansett hva slags celComplex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. In mammals, about 50% of the mitochondrial DNA is encoding protei
Tracing local hyaluronan after ocular anterior segment trauma
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Hyaluronan (hyaluronsyra) är en högmolekylär polysackarid som förekommer i all biologisk vävnad i olika koncentrationer, med särskilt höga nivåer i bindväv. Den kan bildas av de flesta celltyper. På molekylär nivå föreligger den i form av ett nystan, har förmågan att binda stora mängder vatten, och har en uttalad pseudoplasticitet. HyaHyaluronan has been found in the eye in varying amounts and at different sites. It is involved in physiological and pathological processes, though many aspects of its bio-logi-cal functions are still unclear. We have studied the role of iris tissue in hyal-uro-nan production in the anterior segment of the eye, and its changes after trauma. After peripheral iridectomy or argon laser treatment, the
Closed-loop combustion phase control for multiple combustion modes by multiple injections in a compression ignition engine fueled by gasoline-diesel mixture
Partially premixed combustion with low octane fuel aims to reduce NOx and soot emission simultaneously without fuel consumption penalty. Cylinder pressure based combustion phase control is an essential technology for partially premixed combustion. A novel closed-loop combustion phase control strategy for multiple combustion modes is proposed in the current study. The combustion modes are classifie
Combustion sensitivity to the nozzle hole size in an active pre-chamber ultra-lean heavy-duty natural gas engine
Active pre-chamber configurations are considered a valuable solution for improving the operation of the internal combustion engine, in the view to overcome the many challenges it has been made to face. Combining this technology with the use of natural gas, a fuel that has increasing availability and interest in the market share, it is possible to burn ultra-lean mixtures (with air-to-fuel ratios,
Arbitration on whose terms? - A TWAIL analysis of investor-state arbitration through Bilateral Investment Treaties
Denna uppsats studerar skiljeförfarandemekanismen i Convention of the Settlement of Investment Disputes Between States and Nationals of Other States (ICSID-konventionen) och hur den används i bilaterala investeringsavtal (BITs). Ämnet analyseras utifrån Third World Approach to International Law (TWAIL), vars synsätt utgår från att det finns en strukturell orättvisa i folkrätten och en dominans av This thesis examines the arbitration mechanism of the Convention of the Settlement of Investment Disputes Between States and Nationals of Other States (the ICSID convention) and how it is used in Bilateral Investment Treaties (BITs). This is done from a Third World Approach to International Law (TWAIL) perspective. The main hypothesis of TWAIL is that inequality is embedded in international law, w

Abundances of iron-peak elements in disk and bulge giant stars from high-resolution optical spectra
Solen och alla stjärnor som vi ser på natthimlen tillhör vår Galax - Vintergatan. Vintergatan är en spiralgalax med en utbuktning i dess centrum - bulben. För att förstå hur Vintergatan blev till måste man ha en bra uppfattning om bulbens ursprung. Under många år trodde vi att vi visste hur bulben och hela Galaxen hade formats, men ny teknologi, förbättrade teleskop och instrument samt simuleringaContext. The formation and evolution of the Galactic bulge and the Milky Way is still a debated subject. Observations of, e.g., the X-shaped bulge, cylindrical stellar motions and young stars in the bulge have suggested that the bulge formed through secular evolution of the disk and not through gas dissipation and/or mergers, as thought previously.\\ Data. We use high-resolution optical spectra of
