Thermal dispersion mass flow meters, often called thermal mass flow meters, rely on the transmission of heat from a body to a gas flow. Inside the flow meter sensor head, a heated resistance thermometer (RTD) is electronically compared with an unheated RTD sensor. As a gas passes the heated RTD, heat is transferred from this sensor to the gas, and hence the RTD is cooled, thereby reducing the temperature difference between the two sensors. Heat transfer from the RTD to the process gas is based…

Abstract: Electrochemical machining (ECM) is a technique of eradicating metal by an electrochemical procedure. It utilizes an electrolyte and electrical current to ionize and eradicate metal atoms. Electrochemical Machining is a relatively ancient machining system which basis were laid way backside in the 19th century. The process has enhanced extremely everlastingly since, thus becoming an extremely defined practice with gigantic limitless application possibilities across engineering. In this…

“Business ethics are moral principles that guide the way a business behaves. The same principles that determine an individual’s actions also apply to business. Acting in an ethical way involves distinguishing between “right” and “wrong” and then making the “right” choice.” Business enterprises have tremendous potential to transform people 's lives and to alleviate poverty through generating economic process. They manufacture products and services that customers need and they generate jobs. By…

Forensics is defined as scientific tests or techniques used in connection with the detection of crime. The chemical advancements developed in this field stem from hundreds of years ago, where poisons, especially arsenic, were an extremely popular way of killing people. This led to the first organized criminal investigation using a chemical test in 1752. This was the Blandy Trail, where the suspected poison was arsenic, and tests were conducted to prove so. Some of these early tests include…

Rocket Lab Experiment #4 Lilly Creswick (w/ Michelle Kubrin) Colorado School of Mines Chemistry 121 section 2AB Tace Rand Dr. Caster, Dr. Falconer, Dr. Sower September 20, 2016 Abstract: The Rocket Lab aimed to create a successful rocket made out of a pipet bulb filled with Acetylene and Oxygen gas. Different ratios of Oxygen and Acetylene gas were used to determine what would create the largest propulsion and launch the rocket bulb the furthest. A pipet bulb was used as the…

3. Results and discussion 3.1 Microstructural characterization The Roman spectrum of Cr-DLC coating was shown in Fig.1. The overlapped D peak and G peaks located at 1363cm-1 and 1564cm-1 were obtained after fitted with Gaussian curves, respectively. It’s well known that the content of the graphite crystal was closely related to the value of ID/IG [22]. And the ratio of intensity between D peak and G peak (ID/IG) of Cr-DLC coating could be calculated by the fitted curve. The value of ID/IG was…

INTRODUCTION “What is globalization?” and “what are its negative effects” are the questions which we should begin with. There are numerous definitions pertaining to globalization; Merriam Webster’s dictionary defines globalization as “the act or process of globalizing: the state of being globalized; especially: the development of an increasingly integrated global economy marked especially by free trade, free flow of capital, and the tapping of cheaper foreign labor markets.”(Merriam Webster)…

A BADGE OF HONOR? “Our society seems to place a moral value on sleeping as little as possible… . Saying ‘I’m tired and I’m going to sleep’ is viewed as being lazy.” Sleep research Dr. Eve Van Cauter (Brody) provided this adequate description of how our high demand, 24 hours a day, seven days a week world, is robbing substantial numbers of people of sleep. For many Americans “inadequate sleep is a workaholic’s badge of honor” (Brink). We proudly pin on our badge of sleep deprivation and polish…

HEMISECTION: A CASE REPORT ABSTRACT The loss of posterior molar can result is several undesirable sequelae including shifting of teeth, collapse of the vertical dimension of occlusion, super eruption of opposing teeth, loss of supporting alveolar bone and a decrease in chewing ability. The treatment options to replace severely damaged and possibly unrestorable teeth include removable partial denture, fixed partial denture and dental implants. A guiding principle should be to try and maintain…

Friction is a crucial phenomenon in metal cutting which is very complex to model. It has a significant effect on the amount of power required for removing a given volume of metal, surface quality of the finished product, and the extent of tool wear. However, many studies assume no friction in the metal cutting process due to lack of experimental techniques to directly measure the coefficient of friction. Sticking and sliding regions are the two contact regions along the tool-chip interface. A…
