Cause of pain In the case study, the 40-year-old male patient suffered from retrosternal pain that occurred once he laid down after consuming food. The patients’ retrosternal pain is a result of a spontaneous muscular spasm also known as heartburn. According to the Mayo Clinic, “Heartburn is a burning pain in your chest, just behind your breastbone. The pain is often worse when lying down or bending over.” The heartburn that the patient is experiencing is associated with the regurgitation of…

1. INTRODUCTION 1.1 OBJECTIVE The objective of this report is to give an insight into the world of supersonic flight in hopes that students and lecturers attending the annual, week-long “Learning and Sharing Festival” will educate themselves more about supersonic planes. 1.2 SCOPE This report discusses the design features and the functions of a general supersonic aircraft. It will also cover advantages and disadvantages, the target users and the possible…

Production Needs Under Armour currently manufacturers most of their products by third parties overseas. “In 2006, our products were primarily manufactured in Asia, Central and South America and Mexico” (Under Armour, 2016). However, their distribution center remains in Maryland. Only a select number of products though are filtered through their distribution center. When Under Armour enters the golf equipment business there are numerous factors to consider in obtaining the raw materials,…

Triethanolamine effects are enhanced if the products are left on the skin, such as moisturizers. Some of the safe ingredients to look out for are: Avobenzone is commonly used and effective against sun filtering. Physical blocking agents zinc oxide and titanium dioxide have not been linked to any adverse health effects or any estrogenic side effects. Mexoryl SX, Mexoryl XL, and Tinosorb appear to be safe. The FDA’s 2007 draft on sunscreen safety regulations clearly stated: “FDA is not aware…

Abstract Biofilms cause many problems in the drinking water distribution systems (DWDS) and are difficult to remove via conventional disinfection methods. Halogenated furanones produced by Delisea pulchra can hinder biofilm formation and maintenance and look promising as an alternative solution that can be used either as a preventive measure or co-treatment against biofilms in DWDS. However, limited toxicology studies that have been done on halogenated furanones formed as by-products of…

replacement tooth, bridge, or set of teeth. Dental implants may be an option for people who have lost a tooth or teeth due to periodontal disease, an injury, or some other reason. What are dental implants made of? Dental implants are typically made of titanium, a biocompatible (not harmful or toxic to living tissue) material that is accepted by the body and serves as a solid and durable foundation for replacement teeth. Your natural bone locks the implant into place by fusing (attaching…

Welding There are 5 main types of welding process commonly used in industrial welding. They are; Gas Metal Arc Welding, oxy acetylene, Gas Tungsten arc welding, flux core, and Shielded metal arc welding. All welding procedures are important and useful for a variety of things. Welding is the process by which two or more pieces of metal are joined or metal has material added to it to fill a hole. Welding process work by heating the base metal, or the material being on, to a liquid state. They…

1 - Problem - How do I create a container that will keep my egg from cracking, sufficiently cushion the egg, hold it in place, and lower the pressure of it hitting the ground, without using any liquids or food item(ex. peanut butter)? How do I also make the project light enough to minimise the pressure of the impact on the ground on the egg? In addition, how can I keep the project straight and increase the air resistance of the project without a parachute? 2 - Hypothesis - If I were to use a…

Corrosion is when metals or other materials corrode over time. “Corrosion is a two-step process that requires three things: a metallic surface, an electrolyte, and oxygen. During the corrosion process, surface-level metal atoms dissolve into an aqueous solution, leaving the metal with an excess of negative charge.”(Corrosion, Boundless Chemistry, First two bullet points) The nail will undergo a corrosion process as it is placed in the cup filled with salt water. However, depending on the coating…

The Nanotube Introduction: Nanotubes, specifically the carbon nanotubes are just one of the handful of structures engineers and scientist use today that fall in the nanoscale category. Structures in the nanoscale category are usually between 1-100 nanometers, which one nanometer is one-billionth the size of a meter. A confusing yet beneficial property found in materials at the nanoscale is a concept call quantum called quantum mechanics. In quantum mechanics the laws of classic or Newtonian…
