Research Showcase

Guidelines for Submission of Papers

• ·         Submissions are accepted year-round.  The Showcase is updated at least one time per semester.
• ·         The principal author must be an employee of Cape Fear Community College.  Faculty and staff members, full-time and part-time are invited to participate.
• ·         To be eligible for inclusion, the paper should be submitted through the primary author’s department chair or department head.  Departments are, of course, free to establish additional internal review policies or procedures. 
• ·         Department chairs will submit the paper via email to cburwell@cfcc.edu for inclusion on the Showcase webpage.
• ·         Textual works should be sent as an attachment in PDF format.  File limit size is 5 MB.  An abstract--in Microsoft Word or Google Doc format—of no more than 200 words should also be attached.  Authors are invited to include an image in JPG or PNG format image to illustrate the submission.
• ·         Submissions are assumed to be the original work of the author.  Proper citation of any non-original work should be done according to the style manual of the author’s discipline.  All necessary permissions for reuse of previously published materials are the responsibility of the author.
• ·         Authors are responsible for compliance with all US copyright laws and the Acceptable Use Policy of Cape Fear Community College. 
• ·         Authors are free to simultaneously submit papers to other publications.  Authors should be aware that the Research Showcase is openly viewable on the Internet.  Published books and articles available through the Library are linked on a separate page.
• ·         Those who would like to submit but have a larger file or different file format or any other questions should contact us at cburwell@cfcc.edu.

Octet op.32 - Ernesto Ferreri

Octet op.32, is a composition finished this summer (2013). It began with the rearrangement of some symphonic fragments from 1979, some of this music was in my portfolio for my audition into Manhattan School of Music.  It has a clarinet, bassoon, french horn, 2 violins, viola, cello and string bass.

What does op. 32 mean? Publishers assign "opus numbers" to a composer's work, usually in the chronological order of its appearance. Self-publishing composers may assign their own.

This octet is in two movements, that is, two discrete pieces that sound generally complete if  given separately, a composer may compose as many movements as they wish to.

The "performance" of the octet given here is makes use of on-board synthesis from a notation program (FinaleTM). It is important to understand however, that the notation itself is a "recording" of the composition, in fact with more "fidelity" than the audio-- the musical score tells performers what precisely to play. Not only pitch and rhythm is precisely notated, but also dynamics (the quality of loud or soft and various shadings) and tempo indications to set the speed of the music. From the full score a separate part is extracted for each instrument.

This octet would be classified as "chamber music" as opposed to orchestral or symphonic music as it is a smaller ensemble than an orchestra which usually has 30-100 players.

Particle size, flow speed, and body size interactions determine feeding rates of a solitary ascidian Styela plicata : a flume experiment

ABSTRACT: Benthic suspension feeders are a primary conduit for the transfer of carbon from the
water column to the benthos. As such, factors that influence their feeding require mechanistic
study and quantification. In this flume experiment, the clearance rate of the solitary ascidian
Styela plicata varied as a function of flow speed, body size, and particle diameter. At all flow
speeds and body sizes tested, clearance rates increased directly with particle diameter to ~10 μm.
As particle diameter increased further to ~32 μm, clearance remained constant or declined
depending on flow speed. At 3 and 22 cm s-1, clearance remained constant with particle diameter
>10 μm. At 14 cm s-1, clearance sharply declined as particle diameter increased above 10 μm. In
general, clearance rates increased with body size across all particle diameters. However, allometric
exponents relating clearance rate to body size, which ranged from 0.28 to 0.62, were lower than
expected (~0.67) due to the confounding effects of water flow, to which clearance rate responded
in a non-linear fashion. We fit our measurements to a 3-dimensional surface that relates clearance
rate, body size, and flow speed. These surface fits show that clearance of small particles (<10 μm
diameter) was maximal at intermediate flow speeds (~12 cm s-1) and decreased at both faster and
slower flow speeds. This ‘unimodal’ response is consistent with predictions of suspension-feeding
theory. In contrast, clearance of large particles (>10 μm diameter) decreased steadily as flow
speed increased from 3 to 22 cm s-1.
