We report a population based case-control study of exposure to pesticides as risk factor for non-Hodgkin lymphoma (NHL). Male and female subjects aged 18-74 years living in Sweden were included during December 1, 1999, to April 30, 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnaire. In total 910 (91 %) cases and 1016 (92%)

A simplified Fokker-Planck model for the lay-down of fibers on a conveyor belt in the production process of nonwovens is investigated. It takes into account the motion of the fiber under the influence of turbulence. The emphasis in this paper is on the development of a numerical procedure to solve the model. We present a semi-Lagrangian scheme that accurately captures the fiber dynamics and conser

The purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length. However, a different picture is portrayed in the manufacturing industry, where the purchasing strategies are mostly long-term to secure supply for production. Industrialized building is at the crossroad between construction and manufacturing, which rThe purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length.

We created a computational optical model of spherical fish lenses that takes into account the effects of the peripheral layers that differ in cellular composition from the bulk of the lens. A constant refractive index, except for the lens capsule, in the outer about 6 % of lens radius made it possible to uniquely infer the refractive index gradient in more central layers from a known or desired lo

File sharing is causing an enormous debate over the issue of copyright law and freedom of information on the internet. Just recently, the Swedish file sharing network The Pirate Bay was sentenced to pay 30 million kronor to the media entertainment industry, who prosecuted the owners for illegal piracy of copyrighted material. This essay examines weather or not free file sharing, unbound by legal c

Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 x 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703

It is our impression that Gordon Pask’s writings cover fundamentals for large parts of the widely expanding fields of Cybernetics and Systems Theory. Thereby, and by his lecturing activities, he has become a unique figure in maintaining a kind of unity of the field of Cybernetics, well in accord with Wiener’s view (“control and communication in the animal and the machine”; cf[26]). And that, with

In order to determine the true effects of new medicines, new medical approaches and health care policy, one has to resolve problem of selection faced in many econometric studies. This paper investigates the models that take account of this problem in nonexperimental data. This data, contra to experimental data sets, exhibit both some special characteristics and possibilities. Starting from the dat

Aim: This study evaluated the contributions of various prenatal and postnatal predictive factors to a documented high prevalence of ophthalmological abnormalities in children aged 6.5 years who were born extremely preterm. Methods: We carried out a prospective population-based study of all children born in Sweden at a gestational age of 22 + 0 to 26 + 6 weeks based on the Extremely Preterm Infants

INTRODUCTION: There is an increasing number of elderly in society and some of them may have an abdominal aortic aneurysm (AAA). The prevalence of AAA in octo-And nonagenarians indicates that this number could be substantial. The question is: is there an age limit for repair? This complex question incorporates ethical, political, economic and medical aspects. To answer part of this question a revie

In response to growing criticism of new public management reforms, the Nordic countries have introduced so-called trust reforms aimed at transforming public sector management and leadership. There is, however, scarce knowledge about the role of organizational concepts in national trust reform and how they are translated, not least in a comparative perspective.

Lantbruket rankas konsekvent som en av de mest riskfyllda sektorerna i Sverige såväl som i många andra delar av världen. Förutom lidande för den enskilde beräknas dödliga och icke dödliga skador i svenskt lantbruk kosta samhället 2 – 3 miljarder kr per år. I Sverige inträffade det cirka 5 000 olyckor på jordbruksföretag 2004. Detta innebar att minst en olycka inträffade på 8% av svenska gårdar som

This study utilises Correspondence Analysis to investigate the subsistence strategies of Scandinavia's Middle Neolithic Culture of the Pitted Ware Culture (PWC). The aim is to understand subsistence strategies' regional and local expressions across larger geographic areas. The studied material is derived from PWC settlements in Gotland, Åland, Central-Eastern Sweden, and South Scandinavia.

De senaste åren har tre högt sittande svenska politiker gjort sig skyldiga till, eller blivit anklagade för, brott, vilket fått stor mediebevakning. Vidare är brottslighet i Sverige bland de mer framträdande politiska ämnena. Politikens inställning har under en längre period präglats av ett tufft förhållningssätt med hård retorik och känslostyrda förslag för att lösa ‘brottsproblemet’, som beskriv

This paper analyzes the effect of overlapping Trade blocs on Trade Facilitation. Using the time, documents and costs incurred as trade facilitation indicators, simulations show interesting yet important effects of an increase in Regional Trade Agreements on trade costs. The results suggest that when it comes to increasing regional trade agreements by 1%, costs are associated with an increase via t

Denna studie tillämpar Van Dijks kritiska diskursanalys på tre tal som hölls av George W.Bush, Laura Bush samt Collin Powell under år 2001 efter attackerna på World Trade Center. I och med att de i dessa tre tal hävdar att kriget mot terrorismen även är en kamp för de afghanska kvinnornas rättigheter, är det av relevans att tillämpa en kritisk diskursanalys för att identifiera relevanta retoriska
