Excitation of Radial P-Modes in the Sun and Stars

P-mode oscillations in the Sun and stars are excited stochastically byReynolds stress and entropy fluctuations produced by convection in theirouter envelopes. The excitation rate of radial oscillations of starsnear the main sequence from K to F and a subgiant K IV star have beencalculated from numerical simulations of their surface convection zones.P-mode excitation increases with increasing effec

Charge state evolution of uranium in electron beam ion trap

We present a calculation scheme with significant modifications and improvements for determining the ionization balance and the ion temperature evolution in an electron beam ion trap (EBIT). The scheme is applied to uranium and nitrogen ions using a specific set of EBIT operating parameters. The calculation results are compared to the experimental data. Rates for the individual atomic processes in

Numerical simulations using an improved calculational scheme for ion charge state distribution and ion temperature evolution in an EBIT

A calculation scheme with significant modifications and improvements for determining the ionization balance and the ion temperature evolution in an electron beam ion trap (EBIT) is presented. The scheme is applied to thorium, tantalum and oxygen ions using a specific set of EBIT operating parameters. The results of the calculation are compared to experiment and previous calculations. Rates for the

Observing binaries with Gaia - the global picture

ESA's Gaia mission will observe huge numbers of binaries with a largerange of periods. The present contribution presents results from somelarge-scale simulations, based on a simplified population synthesismodel Galaxy consisting mostly of binaries. The results are 'typical'solution-numbers and -types, for stellar samples at different distancesfrom the sun. As in previous studies, there are marked

The Possibility of Resonance-Enhanced Two-Photon Ionization of Ne and Ar Atoms in Astrophysical Plasmas

We consider possible schemes for the resonance-enhanced two-photon ionization (RETPI) of Ne and Ar atoms under the action of bichromatic radiation of intense resonance lines of HI, HeI, and HeII in a radiation-rich astrophysical plasma. The ionization rate is comparable to or exceeds the recombination rate in rarified astrophysical plasma, which leads to the accumulation of singly ionized ions wit

Kvinnan, Våldet och Lagen

This essay is a survey about how important laws regarding women, has lead forward to present day's legislation regarding women battering in Sweden. We have chosen to concentrate on the battered woman's situation. The laws has through centuries given the man a right to beat his wife. Has the way of looking at women's situation in society changed the laws regarding women battering? Has t

Det får revisorn stå för! - En analys av revisorns skadeståndsansvar enligt 29 kap. ABL, med särskilt fokus på det externa skadeståndsansvaret

Denna uppsats berör revisorns skadeståndsansvar enligt 29 kap. aktiebolagslagen (2005:551), ABL. En revisor som när han eller hon fullgör sitt uppdrag uppsåtligen eller av oaktsamhet skadar bolaget ska ersätta skadan. Detsamma gäller om skadan drabbar en aktieägare eller någon annan genom en överträdelse av ABL, tillämplig lag om årsredovisning eller bolagsordningen. Uppsatsen fokuserar huvudsakliThis essay is about the auditor’s liability for damages according to the Swedish Companies Act (2005:551). If an auditor, due to intent or negligence, causes damages to the company during his or her mission as an auditor, he or she shall indemnify the company. The same is true if the auditor causes damages to a shareholder or someone else due to a violation of the Companies Act, the applicable law

The Trans-European Transport Network - A closer look at Policy Failure and the effects of Path Dependence

There is a trans-European transport network policy on the supranational level that aims to connect Europe with efficient, sustainable, safe and economically viable cross-national transport infrastructure. Because of this, one could expect EU funding to focus on rail infrastructure, as it has proven to be a low polluting, cost effective and an efficient mode of cross-national transport. However, as

A simple model for the BFKL-DGLAP transition in deep inelastic scattering

A simple model is presented which interpolates between the DGLAP and BFKL regimes in deep inelastic cp scattering. This model is based on the CCFM and LDC models, and it is simple enough to provide an intuitive picture of the transition region between the two domains. Results are presented for both fixed and running coupling; for fixed coupling the transition between the domains occurs at a consta

Determination of Low Energy Constants and testing Chiral Perturbation Theory at Next to Next to Leading Order

We present the results of a search for relations between observables that are independent of the Chiral Perturbation Theory (ChPT) Next-to-Next-to-Leading Order (NNLO) Low-Energy Constants (LECs). We have found some relations between observables in $\pi\pi$, $\pi K$ scattering and $K_{l4}$ decay which have been evaluated numerically using the old fit (fit 10 in~\cite{Amoros:2001cp}) of the NLO LEC

QCD multiplet bases with arbitrary parton ordering

We develop an algorithm for recursively constructing orthogonal multiplet bases for the color space of QCD, for any order of partons and any Nc. This recipe is then applied for explicitly constructing some of these bases. Using the bases, a corresponding set of Wigner 6j coefficients are calculated. The Wigner coefficients offer a method of using multiplet bases without resorting to the explicit e

Monte Carlo generators

I discuss some recent development of Monte Carlo event generators and point out some problems. Starting with the issue of combining matrix element generators and parton shower algorithms, I will continue with discussing the problems associated with describing small-x final states and discuss some recent model developments for describing multiple partonic scatterings and underlying events in hadron

Inclusive and exclusive processes with a leading neutron in ep collisions

The inclusive and exclusive processes associated with a leading neutron in ep collisions at high energies are described using the color dipole formalism. We demonstrate that the available experimental HERA data on the xL (Feynman momentum) distribution of leading neutrons can be very well described taking into account the nonlinear (saturation) effects in the QCD dynamics. Moreover, we present our

NPDF constraints from the Large Hadron Electron Collider

An updated analysis regarding the expected nuclear PDF constraints from the future Large Hadron Electron Collider (LHeC) experiment is presented. The new study is based on a more flexible small-x parametrization which provides less biased uncertainty estimates in the region where there are currently no data constraints. The effect of the LHeC is quantified by directly including a sample of pseudod

Improving the description of multiple interactions in Herwig

The modeling of multiple parton interactions in Monte Carlo event generators is a crucial part not only for the dressing of signal processes but also to describe data with a minimum bias on the event selection. Much work has and will be put into the theoretical framework and the numerical implementation of these models. In this contribution, we document various improvements of the multiple parton

The Shape of the Correlation Function

The correlation function measured in ultrarelativistic nuclear collisions is non-Gaussian. By making use of models we discuss and assess how much various effects can influence its shape. In particular, we focus on the parametrisations expressed with the help of Lévy-stable distributions. We show that the Lévy index may deviate substantially from 2 due to non-critical effects such as non-spherical

Convergence properties of Lévy expansions : Implications for odderon and proton structure

We detail here the convergence properties of a new model-independent imaging method, the Lévy expansion, that seems to play an important role in the analysis of the differential cross section of elastic hadron-hadron scattering. We demonstrate, how our earlier results concerning the Odderon effects in the differential cross-section of elastic proton-proton and proton-antiproton scattering as well
