FeTiP or Fe(Ti+Nb)P precipitates were observed in each sample, while much more incidence was that of the precipitates with niobium as without it. Precipitates without niobium FeTiP were observed only in 5 samples, in a ratio of 8:1,the Fe(Ti+Nb)P being the one with greater values. Oval shapes of Fe(Ti+Nb)P were observed after recrystallization annealing at the grain bounadries and also inside the grain itself. At the grain boundary in the sample with a lower coiling temperature of 565 °C was…
Copper-alloy miniature votive dagger. The pommel is uneven and spherical with a ridge at the top. The pommel narrows into the slightly curved grip. The guard is a square shape with two parallel grooves on each side. The blade narrows into a dulled point. There is a round hole three-quarters of the way up the blade. The back is chipped on the left edge of the blade near the point (as seen in figure 1) and has furrows on the blade below the hole. The front has scratches on the blade above both…
In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…
Fractions Understanding a half When students begin learning about fractions, it is imperative that the educator starts by assessing the students understanding of what a half is. Based on the Australian Curriculum this often takes place in the Year One descriptor (ACMNA016), where it identifies that students are able to half an item and identify how it is an equal portion. Developing a understanding into how to halve an object so both parts are equal, play a vital role in understanding how…
To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…
Laboratory Exercise 1: Anatomy Lab Report Scientist: Eryka Ocasio Ramos Lab Title: Scientific Method and Measurements I. Problem: Is there a correlation between the length of the upper and lower limbs and the height of an individual? II. Hypothesis: The length of a person’s upper limb is equal to 0.4 (40%) of the height of the person. III. Variables: Independent Variable: The people chosen for the experiment. Dependent Variable: Height and upper limb length. IV. Constants: Units of measure, the…
I’d like to start by talking about the value of fifty percent. Fifty percent equals one half of a whole, it is more than zero, but less than one hundred percent, which is whole. Fifty percent is incomplete. Everyone in this room can agree with these statements as fact. It’s a simple matter of taking the value of something. But what about value in people? I am fifty percent Hispanic. I am one half. I am more Hispanic than not, but I am less than hundred percent. If these statements coincide…
The Competitive State Anxiety Inventory-2 Revised (CSAI-2R), is one of the most frequently used instruments in the evaluation of situational anxiety in sports competition. Objectives: The objective of this study was to validate the Tunisian version based on the French version of the Competitive State Anxiety Inventory-2 Revised (CSAI-2R), including the direction and the frequency scales. Method: 418 athletes ranging in age from 14 to 34 years in different individual and team competitions,…
In the next step, the graded response IRT model will be analyzed again for each identified domain, but without the excluded items, and the model fit statistics will be assessed. If the model has a good fit statistics, the best item for each domain will be selected according to the distribution of the threshold values across the latent scale and the discrimination value; item that has threshold values cross the whole latent scale and high discrimination value will be selected. Sample Size Graded…
¥ For how many students do you have Verbal Aggressiveness scores? We have Verbal Aggressiveness scores for 59 students. ¥ What is the mean for the entire sample? The mean for the entire sample is 44.0169. ¥ How do you interpret the mean score? When we interpret the mean score, we should look at the minimum and the maximum scores, so we can see the mean are close to each one. In verbal aggressiveness, the minimum is 26 and the maximum is 65, which indicates that the mean around the middle of…
