I den här uppsatsen diskuterar vi flera möjligheter om hur man kan förklara den kosmologiska konstanten. År 1998 genomfördes observationer av typ 1a supernovor som visade att universums expansionshastighet ökar. Det här fenomenet blev kallat mörk energi. Sedan dess har flera olika hypoteser framlagts. Vi ska studera en teori som använder Yang-Mills-fält som en mekanism som hjälper att klargöra fleThe cosmological constant is one of bigger mysteries in modern fundamental physics and cosmology. In this work we investigate one of the possible interpretations for the cosmological constant. The model a studies spatially-homogeneous mode of the Yang-Mills field known as the Yang-Mills condensate and throughout the work we discuss the dynamics and the time evolution of the homogeneous isotropic Y

The term Space Wars was coined by sociologist and philosopher Zygmunt Bauman to describe the way in which space is fabricated, has turned into a power play. The fabricators are those who are in positions of power and wishing to homogenise cities to fit a specific narrative. This does not offer much room for space to be interpreted, used, and developed in any different way. However, this war has a

This paper is a summary of the discussion within the Diffractive and Low-x Physics Working Group at the 1999 Durham Collider Workshop of the interpretation of the Tevatron and HERA measurements of inclusive hard diffraction.

Astronomerna har nu hittat ett nytt sätt att avgöra en stjärnas ålder. Stjärnan CS31082-001 och grundämnet uran som visade vägen.

Stamceller är en typ av celler som ännu inte har specialiserat sig till en bestämd roll i kroppen, utan kan omvandlas till vilken celltyp som helst. Detta gör dem mycket användbara vid läkning av exempelvis hjärnskador, eftersom vuxna nervceller inte återbildas. Tyvärr är stamceller svåra att utvinna, och kommer de från en annan individ riskerar de dessutom att stötas bort av mottagaren, som vid bWe define a mathematical method that, given the form of an interaction network, defines an energy as a function of the state of the network. When combined with a suitable entropy, it yields a free energy that gives rise to the dynamics of the network, allowing solutions and optimal paths to be efficiently found. This is done primarily with the gene regulatory networks governing cell reprogramming

Mitt examensarbete har varit en utforskande process i hur arkitektur förhåller sig till landskap och natur. Arbetet har resulterat i ett exempel på hur mitt förhållningssätt skulle kunna anpassa sig och landa på en plats med vissa givna förutsättningar. Exemplet tar form i ett galleri och café vars arkitektur följer och ställer ut platsens subtila förändringar och övergångar i landskap och natur.

An overview of the field of Chiral Lagrangians is given. This includes Chiral Perturbation Theory and resummations to extend, it to higher energies, applications to the muon anomalous magnetic moment, epsilon(1)/epsilon and others.

I present the status of the THEPEG project for creating a common platform for implementing C++ event generators. I also describe briefly the status of the new version of ARIADNE implemented using this framework.

An overview is given of general-purpose event generators, especially PYTHIA and HERWIG. The current status is summarized, some recent physics improvements are described, and planned future projects are outlined.

There are experimental evidence for the occurrence of colour reconnection, but the mechanisms involved are far from understood. Previous reconnection studies are briefly summarized, and some potential implications for LHC physics are outlined.
