(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…

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…

Out of all, the burned area showed a significant increase in longleaf pines, (Pinus Palustris) and a decrease in woody species, compared to the unburned area. In fact, it jumped from a frequency of 15 in the unburned area to a frequency of 50; which is two times that of the burned area (see figure 1). Compared to all other species of tree, Pinus Palustris experienced the most increase of frequency. Whereas, Pinus Clausa or sand pine, was only present in the burned area showing that it was a…

This chapter begins with overview of quality concept and six sigma process. 1.1 Quality What is quality? In manufacturing, a measure of excellence or a state of being free from defects, deficiencies and significant variations is known as quality. Quality is a perceptual, conditional, and somewhat subjective attribute and may be understood Sigma is a Greek term .It is used in statistics to represent standard deviation from mean value, an indicator of the degree of variation in a set of a…

The article, “Standard Error of Measurement” by Leo M. Harvill from East Tennessee State University, provided a general introduction of Standard Error of Measurement (SEM). First, it introduced the basic concepts of test reliability. An obtained score or a raw score refers to the number of points obtained by an examinee. The obtained score could be influenced by several factors such as the ambiguity of test items, the fatigue of the examinee, and these factors make the obtained score unlikely to…
