The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

My purpose for this essay is to examine what factors are considered to have high influence on motivation to study and what measures can be taken to enhance student?s motivation to study from a student perspective. The main source of theory for this study has been the classification of motivational factors that has been based on Herzberg?s twofactortheory with complementary theoretical sources. The study is based around two research methods, one survey together with complementary student interviews.
