The new Thessaly test for early detection of meniscal tears provides high level of accuracy in both specificity and sensitivity. The previous evidence based approach for detection of meniscal tears following subjective history was done by carrying out a combination of the McMurray’s test and joint line tenderness. The combination of the two was needed to rule in meniscal tear as McMurray’s test was high in specificity and low in sensitivity (Malanga‚ 2003 ). Specificity of the test was determined

Are heroes born heroes or are they merely a product of the moment? Some people believe that heroes are shaped by the training they undergo while some people believe that heroes simply come about in a moment of crisis. I believe that heroes are a product of the moment by taking advantage of the moment‚ showing true character‚ and not being able to plan for chaos. Heroes that are a product of the moment know how to take advantage of that moment. For example‚ the text about Bob Bush talks about

Linear regression and correlation In linear regression‚ you should follows those instructions: 1. Choose one pair variables‚ first create the scatterplot (using Excel). Do this by simply plotting one variable as the x –axis and the other y-axis. Based on the scatterplot‚ comment on the relationship after fitting a simple curve‚ so you can be creative in pairing the variables. 2. Find the linear regression model by computing either manually or using Excel. 3. Compute the correlation

Laboratory Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine a coefficient of friction
