The Health Benefits of Chocolate Chocolate has become one of the most reputation dessert and flavors in the world. In Meagan Nelson article “A Chat About Chocolate” (2016), chocolate was mentioned as “The Food of the Gods”, the first cacao beans were found by the ancient Mesoamericans in the tropical rainforest of Central America fermented (Meagan, 2016). Besides tasting good, Chocolate have many benefits for people which affect health, beautiful and nervous system. Over the…

grinding, the smoother the chocolate liquor becomes. Cocoa oil is extracted by pressing and straining the liquor. What remains after pressing and straining is the solid mass of chocolate called the cocoa presscake which is broken down in small pieces and pulverized to powder form. The cocoa oil extracted is left to cool down until it becomes a solid pale-yellow block known as cocoa butter which softens at body temperature. Pure cocoa butter can be used directly on the body.…

1. Introduction Polycrystalline materials dominate industrial and technological applications due to their ubiquitous existence, low-cost and ease of manufacturing. During the sheet metal operations, e.g. bending, stamping, drawing and stretching, among the various possible modes of failure, such as wrinkling, scoring, the tearing of a polycrystalline sheet metal is the most common, resulting from an uneven or exorbitant amount of plastic deformation forming a localized neck and therefore…

The aim of the Stress Concentration Experiment was to observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress. With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test…

Once upon a time in the kitchen, Madison the Marshmallow was in her marshmallow bag. Chunky the Chocolate Bar was in his wrapper, and Gary the Graham Cracker was in his box. As the day went on, Madison the Marshmallow decided to go on a walk. That’s when she met Chunky the Chocolate Bar. “Hi, I’m Madison the Marshmallow. What’s your name?” “I’m Chunky the Chocolate Bar. “I was looking for someone to become friends with me.” Madison says. “Oh, cool! I’ll be friends with you. I was looking for a…

In Willy Wonka the Chocolate Factory, Willy Wonka uses his entrepreneurship- a combination of vision, skill, ingenuity, and willingness to take risks to create and run new businesses- and financial capital to produce consumer goods -final goods- such as Wonka Bars and other candies to be sold in stores, a product market -a market in which goods and services are bought or sold- to satisfy the wants -desires that can be satisfied by consuming a good or service- of the people using capital…

Russell Stover’s all milk chocolates have a wide variety of ingredients. The main ingredients needed to make the product are milk, sugar, chocolate, cocoa butter, and soy lecithin. The chocolate and cocoa butter come from the cocoa bean. The cocoa bean comes from a cocoa tree and is grown by farmers around the equator (Barry Callebaut). After the beans are fermented and dry enough the cocoa farmers will bring them to collection centers or cocoa plantations (Barry Callebaut). Next the beans…

Lab 1: Fluctuating Stresses Jinyuan Zhang Due Date: Wednesday, October 14, 2015 Lab Section: 5 Objectives: There are three objectives for this lab. The first objective is applying stresses calculation on a bicycle crank shaft with real-world load. Second objective is visualization of stresses’ fluctuate in process of fatigue failure analysis. The last objective is using the stresses model to find the force is applied on the crank shaft. Sample Calculation: For collecting the…

Small cracks, cavities, and notches in perfect material can dramatically reduce the tensile strength by producing stress concentration around them [ref]. We believe that in mammalian connective bone tissues, canaliculi, osteocyte lacunae, blood vessels and muscle insertions produce stress concentration to delay the progressive spread of minute cracks. Often times the cracks that are running against lacunae, for examples, stop on entering the lacunae, Hessian canals and blood vessels [ref]. We…

One of the major difference is that an IC is a purely a miniaturized electrical circuit where as a MEMS sensor has mechanically moving devices in addition to the electrical circuitry. Other differences are as listed below: [R10] Variation in fabrication steps of an IC vs MEMS include but not limited to the feature size (MEMS require a larger feature size – 0.5 to 1µm whereas IC require a feature size of 0.025µm), mechanical properties (MEMS devices require care greater on Young’s modulus,…
