Regulation of digestive organ. An experimental study on the role of CCK, Bile and EGF

Popular Abstract in Swedish När födan efter en måltid kommer ned i tunntarmen, utsöndras ett protein som heter cholecystokinin, förkortat CCK, ifrån tarmslemhinnan till blodet. Ett ämne som frisätts på detta sätt till blodcirkulationen för att påverka celler i andra organ i kroppen kallas för hormon. CCK påverkar gallblåsan till att dra ihop sig och tömma sitt innehåll samtidigt som bukspottkörtelCholecystokinin (CCK) is known to exert secretory and trophic effects on the pancreas. Its release from the intestinal mucosa is regulated by pancresic proteases in the small intestine. However, knowledge about the type of responding exocrine cells and the time course of events during stimulation with CCK is lacking. Further, the role of CCK in the regulation of growth in other digestive organs is

Towards dynamically reduced mechanisms based on domain splitting

We present a method for developing dynamically reduced chemical mechanisms based on the quasi steady state assumption and a domain splitting procedure. This procedure carries out the reduction within each domain separately according to a steady state selection parameter valid for the corresponding domain. The domains are defined according to a clustering algorithm. The method is applied to calcula

Pancreatic carcinoma in Malmö, Sweden: Clinical, epidemiological and biochemical aspects

Popular Abstract in Swedish Bakgrund Avsikten med denna studie har varit att värdera om det idag föreligger tecken som tyder på att utvecklingen av diagnostiska hjälpmedel och behandlingsmetoder vid cancer i bukspottkörteln har åtföljts av en förbättrad prognos, samt att värdera vilken roll rökning och magsårsoperation kan ha för uppkomsten av sjukdomen. Pancreascancer, cancer i bukspottkörteln, The objective of this thesis has been to assess whether there are indications suggesting that new methods for diagnosis and treatment of pancreatic carcinoma (PCa) has been followed by an improved prognosis, and to assess the possible role of smoking and gastric resection in the causation of the disease. Of the 1,200 new cases PCa diagnosed in Sweden yearly, the majority are older than 70 years,

Strategic value of IS integration in M&A - the relation between IS integration and M&A as a tool for corporate strategy

During the last decade research in the scientific domain of information systems (IS) in corporate mergers and acquisitions (M&As) has become increasingly popular. A not very surprising development regarding the significance of the empirical phenomenon of M&A and the importance of IS for modern business. However, the idea of IS playing an important role in M&As rests on assumptions, ane

Carsim: A System to Convert Written Accident Reports into Animated 3D Scenes

This paper describes a system to create animated 3D scenes of car accidents from reports written in Swedish. The system has been developed using news reports of varying size and complexity. The text-to-scene conversion process consists of two stages. An information extraction module creates a tabular description of the accident and a visual simulator generates and animates the scene. We first des

Parameter estimation of protein chromatographic processes based on breakthrough curves

A methodology for parameter estimation in chromatographic models is suggested in this paper, which is based on breakthrough curves from a given column set-up. Physical parameters are found in two subsequent experiments, one for the mobile phase behaviour and one for the stationary phase behaviour. The estimations are based on flow rate changes and multiple responses. Adsorption parameters are foun

Dynamic Runtime Environments for Grid Computing

In a grid computing context the execution of jobs on remote machines of collaborating institutes often requires the provisioning of more than mere CPU time. Besides libraries and utilities distributed with the operating system in question, further software may be required by the jobs and in such cases need to be installed prior to the job's execution. In grid computing this problem is aggravated b

Evolution of Near and Intermediate Field in A Negatively Buoyant Jet

The purpose of this study is to explore the behavior of a dense jet and bottom plume, composed of brine water of heavier effluent into a quiescent homogeneous ambient, discharged into a receiving body of lighter fresh water (tank). This situation is common in connection with freshwater production from sea water (desalination), which produces a brine waste stream, usually discharged back into sea w

Småländsk världsindustri - en studie om entreprenörer och kluster 1950-2002

The thesis describes and analyzes six companies’ origins and development over the period 1950-2002, a time when the Swedish industrial sector was dominated by companies that were formed in the early 1900s. The firms, situated in the same region, have after an eventful journey become world leaders in the segment of machines with capacity to lift more than five tonnes. Investigations in Swedish busi
