The purpose of this thesis is to evaluate and refute Yvonne Griggs’ claims that the films “House of Strangers” (1949) and “Broken Lance” (1954) are as Griggs deems “genre-based adaptations” of William Shakespeare’s “King Lear.” I argue that the films, although they have some essential elements of “King Lear,” lack intentionality and reception, pivotal components in determining viability as a Shakespearean film adaptation. Using Griggs’ book as my critical background, I will show that these films are better classified under their respective genre categories, Western and film noir, not as “King Lear” genre adaptations. I will also suggest criteria for determining the level of canonicity of a “King Lear” film adaptation. Popularity of films does not determine validity, and a film does not need purported Shakespearean provenance to validate its ratings. Some films, like these, merely reference or pay homage to Shakespeare through use of essential elements of “King Lear”; here, I deem such affinities to be more unintentional than intentional.

Current artificial heart valves are classified as mechanical and bioprosthetic. An appealing pathway that promises to overcome the shortcomings of commercially available heart valves is offered by the interdisciplinary approach of cardiovascular tissue engineering. However, the mechanical properties of the Tissue Engineering Heart Valves (TEHV) are limited and generally fail in the long-term use. To meet this performance challenge novel biodegradable triblock copolymer poly(ethylene oxide)-polypropylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO or F108) crosslinked to Silk Fibroin (F108-SilkC) to be used as tri-leaflet heart valve material was investigated. ^ Synthesis of ten polymers with varying concentration and thickness (55 µm, 75 µm and 100 µm) was achieved via a covalent crosslinking scheme using bifunctional polyethylene glycol diglycidyl ether (PEGDE). Static and fatigue testing were used to assess mechanical properties of films, and hydrodynamic testing was performed to determine performance under a simulated left ventricular flow regime. The crosslinked copolymer (F108-Silk C) showed greater flexibility and resilience, but inferior ultimate tensile strength, by increasing concentration of PEGDE. Concentration molar ratio of 80:1 (F108: Silk) and thickness of 75 µm showed longer fatigue life for both tension-tension and bending fatigue tests. Four valves out of twelve designed satisfactorily complied with minimum performance requirement ISO 5840, 2005. ^ In conclusion, it was demonstrated that the applicability of a degradable polymer in conjugation with silk fibroin for tissue engineering cardiovascular use, specifically for aortic valve leaflet design, met the performance demands. Thinner thicknesses (t<75 µm) in conjunction with stiffness lower than 320 MPa (80:1, F108: Silk) are essential for the correct functionality of proposed heart valve biomaterial F108-SilkC. Fatigue tests were demonstrated to be a useful tool to characterize biomaterials that undergo cyclic loading. ^

Fulgides and fulgimides are important organic photochromic compounds and can switch between the open forms and the closed forms with light. The 3-indolylfulgides and 3-indolylfulgimides exhibit promising photochromic properties and have great potential in optical memory devices, optical switches and biosensors. Copolymers containing 3-indolylfulgides/indolylfulgimides synthesized via free radical polymerizations increase conformation changes and allow the photochromic compounds to be uniformly distributed in the polymer matrix. A trifluoromethyl 3-indolylfulgide and two trifluoromethyl 3-indolylfulgimides with one or two polymerizable N-stryryl group(s) were prepared. Copolymerization with methyl methacrylate provided two linear copolymers or a cross-linked copolymer. The properties of the monomeric fulgide/fulgimides and copolymers in toluene or as thin films were characterized. In general, the photochromic monomers and copolymers revealed similar photochromic properties and exhibited good thermal and photochemical stability. All compounds absorb visible light in both open forms and closed forms. The closed form copolymers were more stable than the open form copolymers and showed little or no degradation after 400 h. The photochemical degradation rate was less than 0.03% per cycle. In films, conformational restrictions were observed for the open forms suggesting that the preparation of films from the closed forms is advantageous. Two novel methyl 3-indolylfulgimides with one or two polymerizable N-stryryl group(s) were prepared. Copolymerization of acrylamide with the methyl indolylfulgimides or the trifluoromethyl indolylfulgimides yielded two aqueous soluble linear copolymers and two photochromic hydrogels. The closed form copolymers containing trifluoromethyl indolylfulgimides were hydrolyzed in aqueous solution by replacing the trifluoromethyl group with a carboxylic acid group. The resulting carboxylic copolymers were also photochromic. The copolymers containing methyl fulgimides were stable in aqueous solutions and did not hydrolyze. Both methyl and carboxylic copolymers exhibited good stability in aqueous solutions. In general, the open form copolymers were more stable than the closed form copolymers, and the copolymers revealed better stability in acidic solution than neutral solution. The linear copolymers displayed better photochemical stability in neutral solution and degraded up to 22% after 105 cycles. In contrast, the hydrogels showed enhanced fatigue resistance in acidic condition and underwent up to 60 cycles before degrading 24%.

Mark Steel started doing stand-up in 1982 in England, around the circuit of bizarre gigs, going on after jugglers and escapologists and people that banged nails into their ear. Then came the Comedy Store and Jongleurs and getting bottled off at The Tunnel, and then a regular slot on Radio 4′s Loose Ends, where he met Joseph Heller, Christopher Lee and Gary Glitter. He did 4 series of ‘The Mark Steel Solution’, one for Radio 5 and the others on Radio 4, and a radio series about cricket, which provoked a whole page of fury in the Daily Express. He presented three series of a sports programme called ‘Extra Time’ which he was very proud of, especially as it went out on Tuesday nights on Radio 5 to possibly no listeners whatsoever. Then there was four series of the lectures on Radio 4, a book called ‘It’s Not a Runner Bean’, another one called ‘Reasons to be Cheerful’, and 3 television series of the lectures on BBC 4 and BBC 2. He has done weekly columns in Socialist Worker, the Guardian and the Independent. He has written a book called ‘Vive le Revolution’, and has been on various panel shows like Have I Got News For You and QI, and on Room 101, and on Question Time he says that he “got very confused when I insulted a member of the Tory shadow cabinet, and afterwards he said I was splendid and invited me for a drink.” And he’s spoken at lots of demonstrations and union meetings and protests, and appeared at quite a few benefits.
