A Comparison Between Mri Findings And Post Operative Reports Of Labral Tears In The Shoulder, Breanna Davis
A Comparison Between Mri Findings And Post Operative Reports Of Labral Tears In The Shoulder, Breanna Davis
CLAS: Colby Liberal Arts Symposium
This experiment investigates the effectiveness of MR arthrography in 28 patients seen at Maine General Orthopedics over the last three years. All 28 patients had an arthroscopic surgery on the shoulders labrum by Dr. Anthony Mancini. I hypothesize the MR arthrography is accurate in diagnosing tears, but not accurate in describing the size and location of the tears. The results found portray the accuracy between MR arthrography findings and the post-operative reports. The study focuses not only on the ability of the MR arthrography to detect a labral tear, but also its effectiveness of finding the location (superior, posterior, inferior, …
Arboretum Pavilion, Jessica Lunde
Arboretum Pavilion, Jessica Lunde
CLAS: Colby Liberal Arts Symposium
Colbys Arboretum is one of the most aesthetically appealing parts of the campus as well as one of the best educational tools we have. However, it is, unfortunately, underutilized by students and by the public. Theres so much to learn from this environment in terms of scientific study of the environment, but also in terms of self-reflection. The arboretum has been described as a place where one can think without pressure and the structure is guided by this idea of escape.
Regeneration After Destruction: An Investigation About Deforestation For Fruit Boxes In The Provinces Of Tungurahua And Pastaza, Ecuador, Julia Rogers
CLAS: Colby Liberal Arts Symposium
The extraction of wood for use as boxes for fruit in the region between Baos and Puyo in the provinces of Tungurahua and Pastaza in Ecuador is a large source of deforestation in the area. The purpose of the study is to examine the effect of this deforestation on the insects, birds, and seedlings to better understand the effects of small scale deforestation in the cloud forest of Ecuador. Six different sites were studied; 2 sites were cut within 2014, 1 site in 2012, 1 site is a forest of 4 to 8 years, and 2 sites are mature forest. …
Demographic Survey Of The Sohisika (Schizolaena Tampoketsana), James Lucas
Demographic Survey Of The Sohisika (Schizolaena Tampoketsana), James Lucas
CLAS: Colby Liberal Arts Symposium
The sohisika (Schizolaena tampoketsana; family Sarcolaenaceae) is a little-known, highly threatened angiosperm endemic to the forest fragments and savanna of the Hauts Plateaux region at Ankafobe Commune, Madagascar. Through targeted surveillance of sohisika at Ankafobe, this study aimed primarily to characterize the demography of the sohisika via GPS mapping of latitude, longitude, and altitude, through dendrometric measures such as height and diameter at breast height (DBH), and through calculation of distribution patterns via Morisitas index. Secondary goals aimed to describe the ecology of the sohisika within its environment and hoped to identify patterns between age class, aspect, habitat, and surrounding …
Demonstration Of Adaptive Optics In A Laboratory Setting, Jianing Yang
Demonstration Of Adaptive Optics In A Laboratory Setting, Jianing Yang
CLAS: Colby Liberal Arts Symposium
We constructed a simple adaptive optics system to demonstrate how a laser guide star coupled with a deformable mirror and wavefront sensor can be used to correct for distortions caused by turbulence in the Earths atmosphere. Adaptive optics (AO) systems are currently implemented at a number of national astronomical observatories, including the W. M. Keck Observatory, Gemini, and Subaru, and is a key design component for the next generation of very large (30-meter-class) ground-based telescopes. Adaptive optics is crucial for improving spatial resolution of ground-based imaging in astronomy. Using AO, we are able to achieve better image quality with the …
