exudates and provide moist environment for wound leading to acceleration of wound healing. The water in hydrogel can be divided into bound water, half-bound water and free water. The quantity of bound water and half-bound water is connected with the number of hydrophilic groups in hydrogel while the content of free water is connected with the three-dimensional

Thomas Jefferson addressed the differences between blacks and indians in order to justify the superiority of whites over the other races. Jefferson’s description of the difference in skin color, character, and mental/artistic capability especially emphasizes the racist undertone. Thomas Jefferson was a Republican who eventually went on to become President in the beginning of the nineteenth century. He frequently encountered issues with indians and blacks, which led him to identifying their differences

Music has always been a part of my life. In definition, it is “vocal or instrumental sounds combined in such a way as to produce beauty of form, harmony, and expression of emotion.” Ever since I was a young child, I have loved music. The strong, steady beats, the entrancing melodies, and the lyrics that vary between heartwarming and heart-wrenching have always had an unexplainable effect on my life. Music seems to have the ability to change certain aspects of my world. Even with my moods, whether

The first time I was introduced to Romanticism in this course, I thought that I would be reading a lot of love poems and novels. But soon enough I realized how wrong I was and understood the real concept of Romanticism. It is a movement of the eighteenth and nineteenth centuries that reacted against the rules in literature, philosophy, art, religion, and politics at that period. Romantic writers meant to break out of what was usual and write about the things that no one dared to talk or write about

There is a certain character that possesses these traits he is also from the movie Transformers.Optimus Prime a brave noble knight that is loyal to his fellow autobots and the leader of them.Optimus Prime uses wisdom at the end of every movie and uses honor to Sentinel Prime leader of the autobots before Optimus.But in Transformers

The Life and Magic of Debbie Reynolds Debbie Reynolds, one of the movie industry’s leading actresses. Who we have tragically lost this past year in December. Being the inspiration she was, she had accomplished a lot in her lifetime. From small town beauty pageants in Utah to big time movies in Hollywood, this woman was one of the most respected and beloved actresses of her time, and still is today. This is only a minute accounting of her accomplishments and actions, but will most likely be the most

The nature of heroism in “Judith” melds the heroic qualities of the pre-Christian Anglo Saxons and the Judeo-Christian heroic qualities. The Anglo Saxon qualities are the skills in battle, bravery, and strong bonds between a chieftain and the thanes. This social bond requires, on the part of the leader, the ability to inspire, and form workable relationships with subordinates. These qualities, while seen obviously in the heroine and her people, may definitely be contrasted by the notable absence

Pre-Assessment Analysis Before starting my math unit on multiplying and dividing fractions, I had the students complete a short pre-assessment to determine their level of understanding and prior knowledge with the concept of fractions. This assessment consisted of twelve individual questions that ranged from understanding concepts to using mathematical processes. The first four questions determine the student’s understanding of the concept of what fractions represent compared to a whole, how to

Decimals Round to Whole Number: Example: Round to whole number: a. 3.7658 b. 6.2413 If the first decimal number is ≥ 5, round off by adding 1 to the whole number and drop all the numbers after the decimal point. If the first decimal place is ≤ 4, leave the whole number and drop all the numbers after the decimal point. 3.7658 = 4 6.2413 = 6 Round to 1st decimal: Example: Round to whole number: a. 3.7658

compute mathematical operations but explain their reasoning and justify why using certain visual strategies such as number lines, number bonds and tape diagrams, aid in the computation of problems. When encountering mixed numbers, students may choose to use number bonds to decompose the mixed number into two proper fractions. This requires conceptual understanding that a mixed number is a fraction greater than one and can be decomposed into smaller parts. At the beginning of the lesson, students are

1. One of the key things that I learned from Developing Fraction Concepts is how important it is for students to learn and fully comprehend fractions. In this chapter, the author talked about how fractions are important for students to understand more advanced mathematics and how fractions are used across various professions. As I was reading this, I thought about all the nurses who use fractions when calculating dosages and how important it is for them to get the dosages correct. If a nurse messed

her students multi-digit number comparison, included in comparing prices. For a student to be able to achieve number comparison, several math concepts have to be understood and demonstrated by the student. Comparing multi-digit numbers as well as decimal placement can be very challenging to teach. Not only do students have to recognize the magnitude of the price on the tag, they have to be able to locate the item in the store, and also be able to compare values of numbers. This can all be hard to

Date: 04.03.15 Practicing Out Math Analysis of Learning: Amelia, Erin, and Taz are gaining skill in one to one counting as we count the number of scoops it takes to fill the tube. They are also being exposed to simple math words like, full, half full, and empty as we measure where the sand is up to in the container. Lastly, they are given the opportunity to make comparisons between the tubes and ascertain which tube make the sand come out faster – the broken tube. Observation: Erin, Taz, and

combined with reasoning (Knaus, 2013, p.22). The pattern is explained by Macmillan (as cited in Knaus, 2013, p.22) as the search for order that may have a repetition in arrangement of object spaces, numbers and design.

because of the Egyption number line. Since the number line is similar to roman numerals, it makes multiplication and division much more difficult (O’Connor & Robertson “An Overview of...” 5). Another reason is that ancient fractions must first be converted to unit fractions, for example, two fifths would equal one-tenth plus one-twentieth (Allen “Counting and Arithmetic” 20).However, as time progressed and ancient math began to become more advanced and the ancient Egyption number line became easier to

Year eight student, Sandra, completed the ‘Fractions and Decimals Interview’ on Monday, March 21. Sandra was required to complete a series of questions, which covered a range of concepts relating to rationale numbers. She submitted her answers in various different forms, including, orally, written, and, physically. The interview ranges from AusVELS Levels 5-8, and focus’ on assisting the student in developing and adjusting strategies, through mental calculations, and visual and written representations
