understand the concepts of lens formula, magnification and power of lens concave lenses when an object is placed at infinity, a virtual image is formed at the focus. the size of the image is highly diminished and point size. when an object is placed at a finite distance from the lens, a...
Each item was graded on a 7-point Likert scale, where 1 was no symptoms and 7 was the most severe symptoms. The mean values for diarrhoea, indigestion, constipation, abdominal pain, and reflux were estimated. The EQ-5D-3L questionnaire was used to obtain data about HRQoL (EQ-5D; http:...
