The boreholes penetrated gneiss, schist, and other crystalline bedrock that has an overall …

The Properties Of Bridgestone Ecopia Solar Car Tires (For The Umr Solar Car Team), Tessa C. Russell

Opportunities for Undergraduate Research Experience Program (OURE)

Much of the energy used by a solar car can be attributed to overcoming rolling resistance, and rolling resistance comes predominantly from the tires. The main goal of this project was to better understand the properties of the Bridgestone Ecopia tires used by the UMR Solar Car Team. Experiments were conducted to obtain this objective, measuring the vertical stiffness, lateral stiffness, and contact patch shape and area. As expected, with decreasing pressure and increasing load, the vertical and lateral deflections increased as well as the tire contact patch area. The stiffness parameters of the tire measured experimentally were used in …

Student Time Management: Student Characteristics Comparison Between Traditional Coursework And Extracurricular Activities, Andreew Ricke

Opportunities for Undergraduate Research Experience Program (OURE)

The trend that extracurricular activities and organizations are important to a college student is increasing. Many students are active in at least one activity or organization outside of class. These activities at the University of Missouri-Rolla range from design competition teams to professional societies, to non-varsity sports, and to special interest's groups Do students who have a high interest in education and learning find these activities more important than their coursework? What other traits could affect preference away from traditional coursework towards non-traditional extracurricular activities?

Miniature Shear Vane Testing On Compacted Silts, James Duehning

Opportunities for Undergraduate Research Experience Program (OURE)

Geotechnical Engineering is a branch of Civil Engineering that deals with soil, rock, ground water and their relationship with the design, construction, and operation of engineering projects (Coduto, 1998). As early as the Middle Ages builders found out through trial and error that the soils stratums underneath their structures had to be competent enough to withstand the stresses induced by these structures. The trial-and-error method continued through the Renaissance and into the Industrial Revolution. (Coduto, 1998) The trial-and-error method turned out to be a very tedious and expensive way of learning.

Carbon-14: Basics Of The System And Its Use In Dating Secondary Mineralizations On Degraded Concrete, Sarah Grondin

Opportunities for Undergraduate Research Experience Program (OURE)

Carbon 14, the radioactive isotope of carbon, provides an isotopic dating system that is very useful in detennining ages for fairly recent, organic, fossilized materials. Paleoclirnatic studies benefit from the use of the carbon system, because carbon 14 can provide an age for a structure and stable carbon isotope variations provide indications about past climate trends. The system can also be used to calculate ages for inorganic materials, specifically building materials partially composed of lime. The creation of the building materials involves burning fossil limestone, and allows the capture of atmospheric carbon dioxide, as the material hardens after construction. Often …

The Online Language Learning Environment: New Roles For The Humanist, James S. Noblitt

Russian Language Journal

Thomas Edison played an important role in improving the technologies needed for the telephone. He was said to have been excited about the educational potential of the new instrument and speculated that it would soon be found in every classroom.

Well, he was right about the educational potential of information and communication technology, but he was wrong about the form the new technology would take.

This chapter raises questions concerning the role humanists will play in determining the development and implementation of information and communication technologies for educational purposes.

Perspectives On Curriculum Construction At The Postsecondary Level: Contexts, Approaches, Principles, Heidi Byrnes

Russian Language Journal

A curriculum is an attempt, wrote Stenhouse three decades ago (1975, 4), to communicate the essential principles and features of an educational proposal in such a form that it is open to critical scrutiny and capable of effective translation into practice.

If one applies that notion of curriculum to the foreign language field in general, and to second- or foreign-language learning in U.S. colleges and universities in particular, one is immediately confronted with a dilemma: how can we speak of a foreign-language curriculum at the college level when a principled approach that is open to scrutiny and that builds on …

Investigations Of The Kinetics Of Liquid Droplets On Soil Substrates Using A Novel Approach: Contact Ratio, Abdelhafiz “Moh’D Adnan” Herbawi

Theses

In view of young’s equation, in which the contact angle “ϑ” and the liquid surface tension γ_lv are the only measurable parameters, the contact angle has been widely conceived as a thermodynamic quantity. Accordingly “ϑ” has been the main focus of most theoretical and experimental investigations. The rate of change in the contact angle has been commonly used as the relevant parameter of spreading dynamics in spite of difficulties associated with contact angle measurements that are well recognized in the literature. Considering that the velocity of the contact line is the pertinent quantity for spreading, it is therefore reasonable …
