Introduction: The human leg is a complex and versatile machine. Designing a prosthetic (artificial) device to match the leg’s capabilities is a serious challenge. Teams of scientists, engineers, and designers around the world use different approaches and technologies to develop prosthetic legs that help the user regain a normal, active lifestyle. Studying the Human Gait Cycle: Each person has a unique way of walking. But studying the way humans walk has revealed that some basic mechanics hold…

Chapter 3: Tests and Implementation. The self compacting geopolymer concrete should possess following properties: 1. Flow ability: It is the property of fresh concrete mix to flow and fully fill complex formwork under an action of its self weight. Slump flow test is performed to check flow ability of concrete. 2. Viscosity: It is the property of concrete to resist flow at a glance when it started. Low viscosity concrete will flow quickly but for a short duration while high viscosity concrete…

Introduction Brass is an alloy, a combination of copper and zinc. It contains around 67% copper and 33% zinc. Commonly, Lead is also added to brass at a concentration of around 2%. Lead improves the machinability of brass. Lead brasses have excellent machining qualities and can be blanked, sheared and milled. Brass does not become brittle at low temperature like mild steel. Brass also has excellent thermal conductivity. Its electrical conductivity ranges from 23 to 44% that of pure copper.…

2. Calcium “Calcium is a metal, a bright shiny metal like all other metals. Calcium is not the white powdery substance most people believe.” Calcium is found in our body very abundantly and it is very important mineral, but its absorption, assimilation and utilization is very difficult in the cell. It is present in the bones as a main component and bones are rigid and hard due to it. We can get it from milk. Bones receives calcium and fills up with it at the age of 21 years. After it, there is…

4.TAGUCHI ANALYSIS FOR THE EXPERIMENTAL RESULTS To examine the 100Cr6 bearing steel through DCT, and to identify the optimum parameter condition of the DCT process, the prediction of the Taguchi analysis is used. The Taguchi analysis and ANOVA, gives the optimized parameter setting and the most influential factor of the DCT process respectively. The quality performance of the deep cryo-treated 100Cr6 steel samples based on the L9 OA was evaluated by conducting the reciprocatory wear tests.…

THEORY Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process required the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part.…

• Use Technology – health apps and fitness trackers are a great way to keep track of your steps, diet, and total exercise and health. Trackers can also track your heart rate, sleep pattern, and water intake. • Smile & Laugh – it really does require more muscles to frown than it does to smile. Studies indicate that smiling can increase your mood instantly. For an extra super boost, get your laughs in. • Go Outdoors – spending time outdoors relieves stress, improves immune system function,…

Polymer - A word, which is connote for large molecules (that a molecule made from simple repeating units called monomers). The monomers are main building block of polymers. Polymers play an essential and ubiquitous role in everyday human life because of the extraordinary range of properties. Polymers are among the most widely used and important type of materials today. Polymers have been with us from the beginning of time; they form the very basis (building blocks) of life. Animals, plants all…

Statistics show that a little over fifty percent of Americans exercise for at least thirty minutes, two to three times a week. These exercises can be anything from lifting weights to taking a walk around the block. You may think it is crazy that these people take the time out of their day to take apart in physical activity, but in reality these people are making an amazing life decision. Some of the benefits of exercising on a regular basis include helping you watch your weight, putting you in a…
