My topic is about using bubble wrap to save the energy! Staying energy efficient is crucial in saving money. When I moved into my first house on campus‚ I was very shocked at the first heating bill. Soon after‚ I decided to find ways to lower my energy bill‚ through means of energy efficiency. After learning about energy efficiency in class‚ I learned that big portion of energy is consumed by space heating. So I insulated my windows with bubble wrap. I recently received my next heating bill to see

Housing Bubbles in Metropolises in China Introduction The boom of house market has emerged accompanying with the soaring development of Chinese economy over the last two decades. Although the prosperity of real estate sector makes contributions to the growth of national fiscal revenue and Gross Domestic Product‚ it also raises a serious problem --- housing bubbles‚ defined as the housing prices deviate too much from its fundamental value (Flood and Hodrick‚ 1900)‚ especially in metropolitan

Business Administration Introduction There is no doubt that chinese real estate bubble has an effect on global economy. Construction can not do without building materials. Therefore‚ global building materials markets may be influenced by this real estate bubble. As a export revenue of building materials‚ U.S. will not avoid this. I will give a report to show my progress about impacts of chinese real estate bubble to U.S. building materials export market. Background According to Halstead (2012)

Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with the bacteria

What Objective measures could we use to test the hypothesis about the cleansing power of antibacterial soap? Rithika: We can test our hypothesis on the cleansing power of antibacterial soap by using both petri dishes and testing the amount of bacteria on our hand before and after using the soap. We will be able to calculate the amount of colonies of bacteria by using the petri dishes. Calculated the difference between both samples will help us to see whether the antibacterial soap will really help us to defeat more bacteria than the regular soap

By examining the historically and scientifically based study‚ I will clarify and substantiate the idea that bubbles can be used as a metaphor to chart social structures and individual connections. The study includes the examination of the chemical composition of bubbles‚ the ascent and demise of a society and the use of a bubble as a metaphor

of Bubbles”. INTRODUCTION Bubbles can be seen everywhere. They are used in kids’ parties and other outdoor activities like picnic. They are also cheap and easy to make. You just need dishwashing liquid‚ glycerin and water. The purpose of this experiment is to prolong the tenacity of bubbles that are made from dishwashing liquid. Another aim is to entertain children who are fond of playing bubbles. However‚ other types of soap like granulated soap can be used in creating bubbles‚ but

Artificial selection is the process in which desired traits are intentionally chose to breed among individuals. Antibacterial resistance is the process in which strong and highly resistant bacterial is selected against weaker bacterial. The selected bacterial then continue to reproduce and create a stronger bacterial population‚ which is resistant to antibacterial materials. Antibacterial resistance is the result of natural selection because the bacterial with highly adaptable
