(a) Langmuir isotherm model Langmuir isotherm is based on the following assumptions: (a) each surface site can be singly occupied, (b) there are no lateral interactions between adsorbed species, (c) the enthalpy of adsorption is independent of surface coverage and (d) energy of adsorption is constant. The Langmuir isotherm is 2.5…

Equation of trendline 1 calculation: m= rise/run = 12/15 = 0.8 c= 5.9 y= 0.8x + 5.9 Equation of trendline 2 calculation: m= rise/run = 25/45 = 0.5 c= 17.6 y= 0.5x +17.6 Point of intersection: Equate both trendlines to find point of intersection 0.8x + 5.9 = 0.5x + 17.6 x= 39 Since x=39, x2= 9 as x2 represents x in descending order. R2: R2 for trendline 1 = 0.98 Correlation coefficient for trendline 1= 0.96 R2 for trendline 2 = 0.98 Correlation coefficient for trendline 2= -0.99 Ratio…

In the 1940s, Raymond Cattell was able to take Allport’s 4000 traits and boil it down through factor analysis. Factor analysis refers to the mathematical consolidation of commonly appearing variables and the summarising of correlating data. He used factor analysis to eliminate synonyms and the very rare or unused traits (Friedman & Schustack, 2014). Cattell was able to reduce the list of traits from over 4000 to 16 personality variables. This reduction in personality variables was attributed to…

The child that I tested for the PLS-5 Test was a four-year-old girl named Katelyn. Katelyn did pretty well for her chronological age, and she tested into the age equivalence bracket of four to seven years old. She is a very bright girl, although there are some weaker areas that she struggled with. Her focus on the test also varied throughout the test. At the beginning of the test, she was focused on the test and answered the questions quickly, but towards the end of the test session, she was…

With the 2016 Presidential elections coming up right around the corner, the date of November 8th continues to flush dread into the hearts of the voters. Considering the almost equally divided voter pool and two equally disliked candidates, the nation is contemplating some of the biggest issues of present day society as a means of distinguishing between the two opposing arguments. Nevertheless, there is one issue that Secretary Hillary Clinton and Mr. Donald J. Trump agree on: income inequality…

Shifting the Burden During the 1950s and 60s, the biggest growth period in American economic history, the rich and the poor alike got wealthy, giving life to the American Dream in. There was as much growth in the top five percent, as there was in the bottom five percent. Welfare state measures were implemented which improved life for much of the population This made it possible for a black worker to get a decent job, buy a home, get a car, and have his children go to school. Large corporations…

Painter’s historical interpretation managed to grab a lot of attention to reconsider America’s virtue and vice in the Progressive Era. Nell Irvin Painter’s 1987 historical monograph, Standing at Armageddon The United States, 1877-1919, focused on the lives of many citizens concerned with positive characteristics of America. Nell began the monograph with an introduction with a sense of fear to readers by asking if the end is near. This might infer that people were standing near a place of…

4.6 Model building for monthly temperature series According to Takele (2012), the process of model fitting involves data plotting, data transformation if necessary, identification of dependence order, estimation of parameter, diagnostic analysis and choosing appropriate model. In this section, a univariate SARIMA methodology is used to model maximum and minimum monthly temperatures of Nairobi. 4.7 Model Identification ACF and PACF plots are used in the identification of the values p, q, P and…

form of transportation is more than the normal household can use. Therefore this requires that the existing power grid is needed to upgrade most of the facilities in the in the grid. This includes the generation, the transmission network, and the distribution systems. This, therefore, requires that massive investment be put in place to provide the required amount of power to the transportation system. Nevertheless, the power grid system may achieve a relief if the transport system is installed…

America prides itself on being a democratic government and a land of equal opportunity, but does it live up to those standards? Incoming inequality is growing in American society, and the effectiveness of democracy is being threatened by this increasing inequality. While America has claimed to make strides toward racial and gender inequality there is a growing gap between the haves and have nots. This income gap is increasing rapidly between the rich and the middle class and the middle class is…
