Linearity: A linear correlation coefficient factor was obtained between the peak area used and the absorbance Verses concentrations of lamivudine‚ zidovudine and nevirapine. The calibration curves were linear for concentrations between 15-150 µg/ml. The linearity of the calibration curves was validated by the values of the correlation coefficients (r2). The correlation coefficients were 0.999 for lamivudine‚ 0.999 zidovudine and 0.999 for nevirapine. The results of the linearity experiment are listed

Vermiculite and Vigna Radiata Background Information: Vermiculite is a common material used in the planting of various types of plants. It is said to be efficient in soil aeration‚ and as a soil medium in germination. Generally it’s PH is 7.0 and varies slightly around the world (Grant‚ A. 2016). The property of Vermiculite tested in this experiment is soil aeration. This is extremely important for plant growth because if a plant is not aerated well CO2 will accumulate and slow down the growth of

Raw Score Method You may wish to test the effects of a number of experimental treatments (counselling approaches): group counselling‚ peer counselling and individual counselling on the self-concepts of students. In this case‚ the independent variable‚ counselling approach has three levels. Necessarily there should be three groups randomly selected from the school population which will be exposed to three different counselling approaches. The dependent variable‚ self-concept‚ may be measured through

Central Coherence: Is it a single construct‚ with a relationship to mentalising? The past 20 years has seen much interest in the development of cognitive profiles and mentalising ability‚ particularly in how they may account for some characteristics of autism spectrum disorders (ASDs). Two of the most influential theories to date are: (i) Weak Central Coherence theory (WCC)‚ which posits that those with WCC focus on detailed (local) features and fail to apply a global context in understanding their

Being nervous is a normal phenomenon prior to taking a test. The degree of nervousness however may be correlated to how prepared someone is for their exam. I personally felt nervous and stressed throughout the 2 or 3 days leading up to the day I took my practical. I was even more nervous as I was standing behind the door‚ prior to walking in to be examined. The anticipation alone can increase the stress levels. However‚ as soon as I entered the lab I started taking deep breaths to decrease my heart

variable The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person‚ time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person‚ groups‚ objects‚ ideas‚ feeling or other thing that researcher want to measure. Variables are thus anything that can take on differing

1 CORRELATION & REGRESSION 1.0 Introduction Correlation and regression are concerned with measuring the linear relationship between two variables. 1.1 Scattergram It is not a graph at all‚ it looks at first glance like a series of dots placed haphazardly on a sheet of graph paper. The purpose of scattergram is to illustrate diagrammatically any relationship between two variables. (a) If the variables are related‚ what kind of relationship it is‚ linear or nonlinear

Ernst Achildiyev November 5‚ 2010 Correlation Between Age and Memory Loss. We have all wondered from time to time as to why the elderly seem to have a much greater falter-prone memory than the younger generations. From recently met people to the digits of their friend’s phone number‚ people seem to lag behind the youth in their memory capability as they grow older. One of the reasons behind this natural phenomena is due to an increase in brain cell loss which onsets around
