The purpose of the current study is to provide students and instructors with a resource to study and teach steelpan through an understanding of the fundamental design and patterns inherent on each instrument. This will be accomplished through an investigation of how an awareness of the symmetrical note layout of the tenor pan, double seconds, triple cellos and six bass can be utilized when learning fundamental music concepts such as scales and chords. Caused by their symmetrical design, the patterns used in steelpan construction interact with the patterns of scales and chords to create commonalities that remain consistent when transposed. When students and teachers are aware of these commonalities, they can be utilized when teaching and learning the instruments. These patterns also inform performance on the instruments, as the commonalities in the transposable patterns lead to recurring stickings. Because of this, the stickings of scales and chords will be discussed throughout the study to determine how the symmetrical design of the instruments can be used to inform stickings. With this study, the author intends to demonstrate the importance of learning the organization of the instrument's note layout, rather than memorizing the location of each note independently. Because of steelpan's cyclical nature, and because the instruments do not conform to a chromatic centric note layout, it can be harder for students to identify the patterns used in steelpan construction. As a result, many novice steelpannists view the note layout of the instruments as a random assortment of notes. The steelpans have been methodically designed, however, and patterns in their note layout do exist. This study should serve as a resource for students and teachers to both acknowledge and understand these patterns.

In recent years, the engineering community has focused attention on selecting durable and low maintenance materials. As a result of recent advances in steel fabrication technologies, stainless steel has risen as a valuable alternative to regular carbon steel for heavy structural elements in addition to the traditional light gage structural elements of common use. The objective of this investigation is to summarize the existing literature concerning on the behavior of cold formed and hot rolled, annealed stainless steel members undergoing axial compression forces. Research related to the subject will be summarized as well as available design practice codes, from where applicable expressions will be investigated and used to perform practical examples.

Low carbon bainitic steels microalloyed with Nb, Ti and V are widely used for the pipeline, construction and automobile industries because of their excellent combination of strength, toughness and weldability. Boron as another major alloying element has been also frequently used in this type of steels since the 1970s. The purpose of adding boron is to improve the hardenability of the steel by promoting bainite formation. / It has been realized that Boron can only be effective as a strengthening element when it is prevented from forming BN and/or Fe23(C, B) 6 precipitates. Therefore, Boron is always added together with other alloying elements which are stronger Nitride or Carbide formers, such as Ti and Nb. However, the formation of complex bainitic structures and the interaction with precipitates at industrial coiling temperature are not adequately understood. / In this study, the effect of boron on the microstructure and mechanical properties of a low carbon Nb-B steel was studied by a hot compression test (50% reduction at 850°C) followed by quenching samples into a salt bath. The microstructures of the tested samples were examined through optical microscopy and SEM; and the mechanical properties of these samples were investigated by micro-hardness and shear punch tests. / The results indicate that during thermo-mechanical controlled rolling (TCR), the final properties of the products not only depend on the applied deformation but also depend on the coiling temperature where phase transformation takes place. According to the investigation, two strengthening mechanisms are responsible for the strength of the steel at the coiling temperature: phase transformation and precipitation. Under optical microscopy, the microstructures of all specimens appear to be bainite in a temperature range from 350°C to 600°C without distinct differences. However, the SEM micrographs revealed that the microstructures at 550°C are very different from the microstructures transformed at the other holding temperatures. / Two strength peaks were observed at 350°C and 550°C in the temperature range studied. It is believed that the NbC precipitates are the main contributor to the peak strength observed at 550°C because the kinetics of NbC is quite rapid at this temperature. The strength peak at 350°C is mainly due to the harder bainitic phase, which formed at relatively lower temperature.
