Evaluation of a method for determinationof glutathionereductase activity inerythrocytes
Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.
ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
Ungdomar som rymmer hemifrån : en kunskapsöversikt
The aim with this thesis is to study how the phenomenon young people who run away from home (runaways) is presented in the research literature. The question at issue in our thesis is: How does research literature present the phenomenon of young people who run away from home? We have selected seven primary documents that we consider gives a broad picture of the knowledge about runaways. We have a postmodern and a hermeneutic approach in our thesis. Our material has been analyzed on the basis of social constructionist theory and the new sociological paradigm of childhood.
Jämförelseförsök mellan ogräsharvning och radhackning :
The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010.
The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing.
In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment.
The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment.
Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20
An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :
During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage. The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment.
