An Exploration of the investigations used to diagnose stroke Methods Used to Diagnose a stroke There are many different tests that can be carried out to help diagnose a stroke. The main way in which they are found is by using brain imaging so that they are able to pick up any visual issues. Brain imaging allows the doctors to understand whether the stroke was ischemic or hemorrhagic. It also allows them to determine how severe it was. Those who have suffered from a stroke must have a brain scan within

Medieval Catapult Investigation I decided to think outside the box for this assignment and have the mindset to try and create a model of a medieval catapult for not only the enjoyment of building it but the understanding of what it was like to live in an era before technology‚ electricity‚ advanced tools and appliances. Trying to figure out what these times were like I tried to create my model to mimic methods used in this era using recycled hard wood‚ soft wood and twine to create an aged look

Introduction. The following is an experiment into temperature change in an exothermic reaction taking place between Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) and also how the concentration of the acid will vary these results. The characteristics of the reaction feature a neutralisation‚ an energy change (shown as a temperature change) that is usually exothermic (gives out heat). The reaction of neutralisation is exothermic because of the bonds being broken and made in the reaction. When

This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests.

Investigation - Solution Colour and Ion Concentration Aim: To investigate whether solution colour can be used to reliably determine the concentration of coloured ions in a solution. Hypothesis: the concentration of permanganate ions in the solution is inversely proportional to the percentage transmission of light through the solution. Dependent variable: concentration of permanganate ions. Independent variable: percentage transmission of light through the solution. Equipment: 20 ml
