General Course Information for PMTX 1014X: Diving Physics & Air Decompres

 Course: PMTX 1014X - Diving Physics & Air Decompres Textbook: For the correct edition of the textbook assigned to a specific class, go to: http://www.nutextdirect.com Course Prerequisite(s): PMTX1012X Course Description: Covers the physical effects of working underwater on the diver's body by factors such as air, sound, and light, with detailed emphasis on pressure and temperature and calculation of formulas to solve diving problems related to physics. Course Learning Outcomes: Describe the characteristics of matter and the components of air and the relationship to hydrostatic and hyperbaric pressure. State the gas laws (Boyles, Charles, Daltons, Henrys, Amonton's -Gay-Lussac's) and explain the practical application in diving. Explain buoyancy as related to Archimedes principle and calculate lift capacities in salt and fresh water. Explain the effects of light in water and the relationship of factors such as depth, density, and turbidity, and refraction. Explain the effects of sound in the water environment and procedures to prevent diver injury. Explain the theory of decompression and the need for decompression procedures. Select proper decompression tables and schedules using the U.S. Navy Decompression Tables; to decompress divers using in-water air decompression, in-water oxygen decompression, surface decompression, perform repetitive dives, and the various emergency procedures related to decompression procedures. Explain how to resolve omitted decompression issues during decompression, surface intervals, or during chamber surface decompression. Explain the theory of altitude diving and procedures to follow for flying after diving. Specified Program Learning Outcomes: Apply formulas associated with decompression and medical aspects of diving. Demonstrate safe operation while working as an outside tender, inside tender, communications operator, and/or log keeper. Dive and tend using surface supply or SCUBA underwater breathing apparatuses in either air or mixed gas modes to perform underwater tasks safely. Perform decompression safely under a variety of situations. Plan a diving job utilizing all available data. Work effectively as a dive team member to achieve goals of a planned diving job and underwater tasks.

Students with Disabilities:
Students seeking special accommodations due to a disability must submit an application with supporting documentation, as explained under this subject heading in the General Catalog. Instructors are required to provide such accommodations if they receive written notification from the University.

Writing Across the Curriculum:
Students are expected to demonstrate writing skills in describing, analyzing and evaluating ideas and experiences. Written reports and research papers must follow specific standards regarding citations of an author's work within the text and references at the end of the paper. Students are encouraged to use the services of the University's Writing Center when preparing materials.

The following website provides information on APA, MLA, and other writing and citation styles that may be required for term papers and the like: http://nu.libguides.com/citations

Plagiarism:
Plagiarism is the presentation of someone else's ideas or work as one's own. Students must give credit for any information that is not either the result of original research or common knowledge. If a student borrows ideas or information from another author, he/she must acknowledge the author in the body of the text and on the reference page. Students found plagiarizing are subject to the penalties outlined in the Policies and Procedures section of the University Catalog, which may include a failing grade for the work in question or for the entire course. The following is one of many websites that provide helpful information concerning plagiarism for both students and faculty: http://www.indiana.edu/~wts/pamphlets/plagiarism.shtml

Ethics:
Ethical behavior in the classroom is required of every student. The course will identify ethical policies and practices relevant to course topics.

Technology:
Students are expected to be competent in using current technology appropriate for this discipline. Such technology may include word processing, spreadsheet, and presentation software. Use of the internet and e-mail may also be required.

Diversity:
Learning to work with and value diversity is essential in every class. Students are expected to exhibit an appreciation for multinational and gender diversity in the classroom.

Civility:
As a diverse community of learners, students must strive to work together in a setting of civility, tolerance, and respect for each other and for the instructor. Rules of classroom behavior (which apply to online as well as onsite courses) include but are not limited to the following:

• Conflicting opinions among members of a class are to be respected and responded to in a professional manner.
• Side conversations or other distracting behaviors are not to be engaged in during lectures, class discussions or presentations
• There are to be no offensive comments, language, or gestures
