The rarefaction technique applied to fossil pollen sequences for analyzing palynological richness, interpreted as a signal of biological diversity of landscapes and vegetation, has been developed since 1988. Errors including population evenness and vegetation disturbance have been considered in this study. Information from two sites is discussed, one with a pollen diagram covering Late-Glacial (La

Objective: To investigate whether the outcome of a pregnancy is related to the time required to achieve that pregnancy (TTP). Design: The distribution of the TTP for pregnancies ending in multiple birth, early (before week 12) and late (weeks 12-28) miscarriage, stillbirth, and extrauterine pregnancy was compared to that of pregnancies ending in singleton birth. Furthermore, the distribution of th

This paper describes a named entity recognition (NER) system for short text messages (SMS) running on a mobile platform. Most NER systems deal with text that is structured, formal, well written, with a good grammatical structure, and few spelling errors. SMS text messages lack these qualities and have instead a short-handed and mixed language studded with emoticons, which makes NER a challenge on

Calcicole plant species are vulnerable to acidification and fertilization, caused by deposition and changes in land use, since they are adapted to nutrient-poor calcareous conditions. In this study we used vegetation data (vascular plants, bryophytes and lichens) from 1964 and 1985 and stored soil samples from 1966 to investigate long-term soil chemistry and vegetation changes in a semi-natural, s

Background: Coronary heart disease (CHD) is the sleading cause of mortality in men and women in Western society. Few studies of CHD have been performed on women or with a focus on cardiac risk factors in women’s lives. Results from studies of men have been generalized to women, which may be inappropriate or even dangerous. Aim: The overall aim of this thesis was to describe women’s experience of a

Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. In the Veterans Administration Heart Failure Trial (V-HeFT) I, the combined use of a nitrate and hydralazine reduced the mortality rate. However, it is not possible to determ

Value Based Management (VBM) has become a common tool for evaluating corporate strategies and projects from the perspective of shareholder value maximization, and can be an important input for corporate compensation systems. But traditional VBM frameworks make no systematic effort to distinguish between changes in performance attributable to macroeconomic fluctuations beyond management's control a

Better understanding of suicidality may improve treatment and care of suicide attempters. This thesis aims at understanding suicidality by investigating suicide risk, sex differences and views of suicide attempters. Suicide risk factors (prospectively determined) differed between the sexes: Older age and high suicidal intent were female risk factors, whereas previous attempts and using a violent
