Women And The Epistemologies Of Pleasure: An Analysis Of Female Sexual Appetites And Practices At Bucknell University

Using an epistemological and feminist lens, this thesis analyzes the political and social forces that actively construct both knowledge and ignorance around female sexual pleasure. It draws from interviews and a focus group, all conducted at Bucknell Unviersity to explore the journeys that women take to gain knowledge about sexual pleasure, and how the sources and cultural mores that women in the twenty-first century rely on or go up against in order to gain such knowledge are often limited, unauthorized or phallocentric. This aids in the construction and perpetuation of ignorance. This thesis looks at how women feel shame or enact self-censorship, regardless of their assertion of knowledge concerning their sexual appetites, which results in consequential ambivalence. For this reason, it concludes that more informed and educational conversations between peers, parents and partners need to take place. These conversations will help to ignite change and to raise awareness about the knowledge and ignorance surrounding female sexual pleasure, which would allow for more pleasurable experiences to take place generally and with a brief over view on Bucknell's campus specifically.

Corrosion Characteristics And Mechanical Properties Of Aluminum Coatings Applied By The Cold Spray Process

Aluminum coatings were applied to 2024-T3 and 7075-T6 aluminum alloys via the Cold Spray process. The coatings were applied to substrateswith various surface preparation and Cold Spray carrier gas combinations. Some samples were coated with an additional sealant with and without a chromate conversion layer. An exhaustive corrosion analysis was then performed which utilized a number of long termand accelerated tests in order to characterize the corrosion protection of the coatings.

Effects Of The Flash Welding Process On Mechanical And Microstructural Properties Of Structural Steel Joints Assessed Using Dest

ASTM A529 carbon¿manganese steel angle specimens were joined by flash butt welding and the effects of varying process parameter settings on the resulting welds were investigated. The weld metal and heat affected zones were examined and tested using tensile testing, ultrasonic scanning, Rockwell hardness testing, optical microscopy, and scanning electron microscopy with energy dispersive spectroscopy in order to quantify the effect of process variables on weld quality. Statistical analysis of experimental tensile and ultrasonic scanning data highlighted the sensitivity of weld strength and the presence of weld zone inclusions and interfacial defects to the process factors of upset current, flashing time duration, and upset dimension. Subsequent microstructural analysis revealed various phases within the weld and heat affected zone, including acicular ferrite, Widmanstätten or side-plate ferrite, and grain boundary ferrite. Inspection of the fracture surfaces of multiple tensile specimens, with scanning electron microscopy, displayed evidence of brittle cleavage fracture within the weld zone for certain factor combinations. Test results also indicated that hardness was increased in the weld zone for all specimens, which can be attributed to the extensive deformation of the upset operation. The significance of weld process factor levels on microstructure, fracture characteristics, and weld zone strength was analyzed. The relationships between significant flash welding process variables and weld quality metrics as applied to ASTM A529-Grade 50 steel angle were formalized in empirical process models.
