We have used image cell analysis to analyse nuclear DNA content on fine needle aspiration biopsies from 96 patients diagnosed to have prostate cancer 1980-81. By stratifying diploid and tetraploid tumours according to a cytometric proliferation index (PI), we suggest a new DNA-classification that is prognostic of death from prostate cancer in multivariate analysis including conventional prognostic
Popular Abstract in Swedish Brännskador orsakade av eld, hett vatten, ånga, frätande kemikalier och elektricitet förekommer i hela världen men det är utvecklingsländerna som är värst drabbade av dessa olyckor. Av de dödsfall från brännskador som rapporterades år 1998 kom 98 % från utvecklingsländer enligt världshälsoorganisationen (WHO). Andelen dödsfall från den afrikanska kontinenten utgjorde 24Background: The burden of burn injuries is in developing countries, the majority of deaths (98%) related to fire burns are in developing countries.These injuries are associated with poverty and are mainly related to accidents with fires in the home environment. Aims: The aims of the thesis were to record the risk factors, causes, magnitude and outcome of burn treatment as well as establish circums
The sun and its heat are two of the most universal symbols known to humanity, yet their supposed meanings vary greatly. The sun can be thought of as a giver of life, but its hot and scorching rays can also be associated with drought and the powers of destruction. The present study concerns the latter view of the sun and related ideas as reflected in the Hebrew Bible and the cuneiform alphabetic te
In Sweden, at least one school fire occurs every day. In most cases, arson is the cause of that fire. The costs for these arson fires are considerable, especially those occurring after school hours. This paper presents data for typical arson fire scenarios in schools and kindergartens in Sweden. This data will later be used to evaluate, with regard to cost and benefit, different active and passive
Nanoethics is one of many new fields that has surfaced as a consequence of the intense ongoing debate on new technology. The term attempts to cover a great span, from free floating nano particles in general to more specific areas such as nano medicine. An important question is in which areas nano ethics can justify its own existence, i. e. to what extent will the application of nano technology giv
The design and analysis of specular radar absorbing materials are investigated throughout the dissertation. Although the topic has been investigated for more than 60 years by many researchers and numerous designs have been proposed, still many technical challenges are remained unanswered. The basic questions are, e.g., the optimal thickness of a design, the possibility of utilization of unconventi
We constructed hydrodynamical model atmospheres for mid M-type main-, as well as pre-main-sequence objects. Despite the complex chemistry encountered in such cool atmospheres a reasonably accurate representation of the radiative transfer is possible. The detailed treatment of the interplay between radiation and convection in the hydrodynamical models allows to study processes usually not accessibl
It is curious that, even though megaliths usually consist of several stones, archaeologists tend to study each of them as single units. In this paper, I argue that it makes much more sense to consider megaliths as assemblages of distinct fragments.
Combustion and emissions formation in a Volvo TD 100 series diesel engine running in a homogeneous charge compression ignition (HCCI) mode and fuelled with natural gas is simulated and compared with measurements for both with and without external exhaust gas recirculation (EGR). A new stochastic approach is introduced to model the convective heat transfer, which accounts for fluctuations and fluid
Vi har systematiskt gått igenom befolkningsbaserade studier, som separat har analyserat frekvenserna för depression och självmord eller självmordsbeteende och deras samband med alkoholberoende, alkoholmissbruk eller riskfylld alkoholkonsumtion. Depressionssjukdomar visade en stark ökning vid alkoholberoende, men endast en marginell ökning vid alkoholmissbruk och riskfylld alkoholkonsumtion. Hela 4
The thesis treats the subject of risk and vulnerability analysis of large-scale technical infrastructures. In particular the focus is on the development of methods for vulnerability analysis of electrical distribution systems. The methods and the concepts behind them should nevertheless also be seen as applicable to other technical infrastructures. Robust and reliable technical infrastructures are
The main purpose of this book is to study the relation between the personal, religious visions and auditions of the internationally known Swedish artist Violet Tengberg (born 1920) and her artistic creations. In the descriptive part of the study the artist’s "outer" activity in the form of artistic creation, development of motives, and exhibitions is presented. Complementary to this presentation,
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Det magnifika skådespelet av erupterande geysrar, varma, rykande källor av skilda slag samt kokande lerpölar är en uppseendeväckande syn. Dessa extrema miljöer av hög temperatur och mycket låga pH-värden verkar långt ifrån livsbejakande. Trots detta finns liv representerat i form av mikroorganismer som här har funnit sina ideala livsmAbstract Hot springs in Iceland can serve as sources of thermophilic, xylanolytic bacteria secreting very thermostable xylanolytic enzymes. The aerobic, thermophilic bacteria Rhodothermus marinus secretes multiple xylanases and xylosidases. One of the xylanases was purified to electrophoretic homogeneity and was characterized. The N-terminal sequence showed no homology with other xylanases. The p
