...I have had one thing on my mind for some time now, and that is to be a portable welder. There aren’t many people who go on portable welding in the country. To solve that problem there needs to be more people to get into welding and chose to travel for welding. Welding is one of the most important jobs in the farmer/ rancher industry. Honestly, portable welding is very important because I can fix the equipment right there where it is at rather than risking taking it to town to the welding shop or to the personal shop to weld on if it is bad enough rather than going to buy or lend a piece of equipment from one of the neighbors. (‘’Welder’’). You can earn $11- $25 depending on the skill level of welding and what kind of welding you are working...

...Welding Before I start my essay I’d like to briefly go over the history of welding. Welding can trace its historic development back to ancient times. The earliest examples come from the Bronze Age. Small gold circular boxes were made by pressure welding lap joints together. It is estimated that these boxes were made more than 2000 years ago. During the Iron Age the Egyptians and people in the eastern Mediterranean area learned to weld pieces of iron together. Many tools were found which were made approximately 1000 B.C. (“History of Welding”). During the Middle Ages, the art of blacksmithing was developed and many items of iron were produced which were welded by hammering. It was not until the 19th century that welding, as we know it today...

...Penta Career Center has changed my overall perception of school, and I am very eager to share how. Penta is a vocational school located in Perrysburg Ohio, that offers programs ranging from cosmetology to welding. Popular programs include automotive technology, masonry, culinary arts, dental assisting, early childhood education, floral design, public safety, and small animal care. And these are just few of the many programs here at Penta. Oak Harbor is my home school, and I came to Penta my junior year to attend Medical Technologies. I plan to return to Penta for my senior year as well! I chose to come to Penta because I wanted to get a headstart in the medical field. I knew that being in Medical Technologies would help me pursue my future career of becoming a licensed dermatologist. One of the things I enjoy here at Penta, is that we operate on block schedule. Block scheduling gives me a good idea of what college will be like. Penta also gives me the opportunity to participate and compete in student organizations, such as HOSA and SkillsUSA. HOSA is an organization dedicated to educating future healthcare professionals.

...Carbon Fibre Composites Compared with Traditional Metallics Name Institutional Affiliation Introduction According to Elaheh Ghassemieh (2011), the automotive industry has experienced lots of changes that occurs by day through the application of composite materials in the manufacturing of motor vehicle parts and body. Several reasons have been advanced in support of this shift from the traditional use of metals. In comparison to the metallic counterparts, many composite materials exhibit relatively greater strength characteristics as compared to the metallic materials. They are also comparatively lighter than the metals and thereby reducing the fuel cost per passenger in the vehicles. It is also believed that composites exhibit higher resistance to fatigue from repetitive use and thus reducing the maintenance cost of the vehicles and increasing the usage time. In reference to Long, A. C. (2005), the composite material can be defined as a material consisting of strong carry-load materials (reinforcements) embedded in a relatively weaker material (matrix). The purpose of the reinforcement is to provide the strength stiffness, rigidity and mechanical properties needed to support the structural load. The matrix on the other hand acts to provide a fixed orientation of the reinforcement and in many cases is more brittle. Question 1 Advantages of carbon fibre reinforced polymers in over metallics Carbon fibre reinforced polymers (CFRP is one of the classes of the composite...

Shipboard fire alone, however, results in more total losses of ships than any other form of casualty. The most common causes of shipboard fire are: maintenance, burning and welding are responsible for nearly 40 percent of all outbreaks. Smoking leads to countless fires that break out when no one expects. Lack of attention, spontaneous combustion and electrical faults are the major causes. The engine room is at special risk from flashbacks in oilfired boilers, leaky pipings carrying oil, overheated bearings and even the accumulation of rubbish (oil rags, dirty oil, tins of oil, etc.). According to Mikhail Grigorevich Stavitskii 1983, if most shipboard fires can be prevented, then who is responsible for preventing them? The answer is that fire prevention is the shared duty of each and every member of the crew. No fire prevention effort or program can be successful unless it involves everyone aboard ship. We have noted that every crewmember is responsible for the fire aboard ship. Similarly, every crewmember has a role in the ship's fire prevention program. Because attitude is so much...

...universal definition for the art. In a magazine published on 2017, art is described as follow: “the communication of intimate concepts that cannot be faithfully portrayed by words alone. And because words alone are not enough, we must find some other vehicle to carry our intent,” (2017). According to ThoughtCo. Arts are generally fallen into three categories: representation, expression and form. This is one of the most effective ways for people of all ages, to express what they are unable to express using words. In this assignment, we are to compare and contrast two sculptures: Statue of Memi and Sabu and the Seated Statue of Gudea. For the sake of understanding, I want you to remember that sculpture is: “the art of carving, modeling, welding, or otherwise producing figurative or abstract works of art in three dimensions, as in relief, intaglio, or in the round,” (Dictionary.Com). It is to mention that, in the ancient time the art of sculpture was ubiquitous. It was so because people in these societies were considered as to be illiterate. That said, sculpture was a powerful way to express emotions as appose to the recent time as we have the opportunity to write books, blogs and many other media related to that end. In an article dated back to the old Kingdom, Dynasty 4, na. 2575-2465 B.C. “that statue was painted with limestone and represents a non- royal couple; however the inscription on the statue suggests they had royal acquaintance,” (The Metropolitan Museum of Art 2013)...

...REPORT WRITING Source: University of Canberra Academic Skills Centre Report Writing Report writing is an essential skill for professionals. A report aims to inform, as clearly and succinctly as possible. Below we give some general guidelines, but you should check with your lecturer for more detail on what is expected. A report is similar to an essay in that both need: • formal style • introduction, body and conclusion • analytical thinking • careful proof-reading and neat presentation A report differs from an essay in that a report: • presents information, not an argument • is meant to be scanned quickly by the reader • uses numbered headings and sub-headings • uses short, concise paragraphs and dot-points where applicable • uses graphics wherever possible (tables, graphs, illustrations) • may need an abstract (sometimes called an executive summary) • does not always need references and bibliography • is often followed by recommendations and/or appendices A report should generally include the following sections. (Sections marked with an asterisk (*) are essential: others are optional depending on the type, length and purpose of the report.) • Letter of transmittal • Title page* • Table of contents • List of abbreviations and/or glossary • Executive summary/abstract • Introduction* • Body* • Conclusion* • Recommendations • Bibliography • Appendices Presentation and style are important.

...Mahatma Gandhi one defined happiness as “when what you think, what you say, and what you do are in harmony.” Barring any better definition of happiness from either positive psychologists, self-help gurus, or any other academic source, I tend to think this is a great summation of the definition of happiness. Gandhi doesn’t say anything about how these things make you feel, rather looks at it from a point of view of harmony between thoughts, expressions, and actions. Since one single accepted definition of happiness doesn’t seem to exist, and happiness is different for everyone, this begs the question; how can you increase your own personal level of happiness? Since WW II psychologist have been studying our brains as they pertain to our mental health. Approximately 30% of people in the USA suffer from some sort of mental disorder (Seligman, Parks, and Steen 418). After we figured out how to treat these 30% of people, psychologists then turned to the remaining 70% of the population with the thinking that “although these people may not be experiencing severe pathology, there is good evidence to indicate the absence of maladies does not constitute happiness” (Seligman, Parks, and Steen 418). The conclusion these psychologists came to was that “…we believe “happiness” is a condition over and above the absence of unhappiness… A review [of the literature] led us to identify three constituents of happiness: (i) pleasure (or positive emotion); (ii) engagement; and (iii) meaning”...
