Completing the Circle: The Actor's Cool Down

Kurtz, Anna 02 May 2011 (has links)
Physically, vocally, and physiologically something happens to the actor in rehearsal and performance that can impact the actor’s everyday life. Practitioners have described this as boundary blurring, emotional hangover, and post-dramatic stress. Even acting as a profession can breed stressful situations for the actor. Actors can combat the blurring, the hangover, and the stress through awareness and process. As a part of process, actors warm-up to prepare their bodies and voices and to transition from real life to stage life. An often ignored aspect of process, but no less significant than the warm-up, is the cool down. After researching the acting experience and the cool down, I introduced several student actors to the cool down during two productions and a workshop. Through these practical experiences, this research, and numerous interviews, I have compiled exercises to facilitate the transition between the acting experience and everyday life.

Factors associated with injuries among marathon runners in Eldoret, Kenya

Chesergon, Fred Kiplagat January 2017 (has links)
Masters of Science - Msc (Physiotherapy) / Extrinsic factors like terrain, hard running surfaces or incorrect shoes have been known to be contributing factors to injury, and intrinsic factors such as poor flexibility, mal-alignment anthropometry, previous injury and running experience have been identified in playing a role too. Little is known about the factors associated with injuries among marathon runners in Eldoret, Kenya. It is therefore important to identify the possible risk factors associated with running injuries in order to prevent further injury and severe long-term complications

Steam Turbine Optimisation for Solar Thermal Power Plant Operation

Spelling, James January 2011 (has links)
The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. Solar thermal power plants are based largely on conventional Rankine-cycle power generation equipment, reducing the technological risk involved in the initial investment. Nevertheless, due to the variable nature of the solar supply, this equipment is subjected to a greater range of operating conditions than would be the case in conventional systems. The necessity of maintaining the operational life of the steam-turbines places limits on the speed at which they can be started once the solar supply becomes available. However, in order to harvest as much as possible of the Sun’s energy, the turbines should be started as quickly as is possible. The limiting factor in start-up speed being the temperature of the metal within the turbines before start-up, methods have been studied to keep the turbines as warm as possible during idle-periods. A detailed model of the steam-turbines in a solar thermal power plant has been elaborated and validated against experimental data from an existing power plant. A dynamic system model of the remainder of the plant has also been developed in order to provide input to the steam-turbine model. Three modifications that could potentially maintain the internal temperature of the steam-turbines have been analysed: installation of additional insulation, increasing the temperature of the gland steam and use of external heating blankets. A combination of heat blankets and gland steam temperature increase was shown to be the most effective, with increases in electricity production of up to 3% predicted on an annual basis through increased availability of the solar power plant. / Hållbar energiförsörjning är för närvarande en av de viktigaste frågorna för mänskligheten. Socialt och ekonomiskt välstånd är starkt kopplat till rimliga energipriser och hållbar energiproduktion. Koncentrerad solenergi är nu etablerad som en tillförlitlig källa av förnybar energi och är också ett ekonomiskt attraktivt alternativ. Koncentrerade solenergikraftverk bygger till stor del på konventionella Rankine-cykel elgeneratorer, vilka minskar de tekniskt relaterade riskerna i den initiala investeringen. På grund av solstrålningens skiftande karaktär utsätts denna utrustning för mer varierade driftsförhållanden, jämfört med konventionella system. Behovet av att bibehålla den operativa livslängden på ångturbiner sätter gränser för uppstartshastigheten. För att utnyttja så mycket som möjligt av solens energi bör ångturbinen startas så snabbt som möjligt när solstrålningen blir tillgänglig. Eftersom temperaturen i metalldelar hos turbinerna är den begränsande faktorn, har metoder studerats för att hålla turbinerna så varma som möjligt under tomgångsperioder. En detaljerad modell av ångturbiner i ett solenergikraftverk har utvecklats och validerats mot experimentella data från ett befintligt kraftverk. En dynamisk systemmodell av de övriga delarna av anläggningen har också utvecklats för att ge input till ångturbinsmodellen. Tre modifieringar som potentiellt kan bidra till att upprätthålla den inre temperaturen i ångturbiner har analyserats: montering av ytterligare isolering, ökning av temperaturen hos glänsångan och användning av elvärmefiltar. En kombination av elvärmefiltar och en temperaturökning av glänsångan visade sig vara det mest effektiva alternativet. Åtgärderna resulterade i en ökad elproduktion på upp till 3%, beräknat på årsbasis genom ökad tillgänglighet hos kraftverket. / QC 20110629 / TURBOKRAFT

Säg Bob! : Sex sångare om nedsjungning

Johansson, Joel January 2021 (has links)
Detta är en kvalitativ studie med kvantitativa inslag med syftet att undersöka sångares upplevelser avnedsjungning efter högintensiv sång. Till en början har specifikt designade sångövningar förmedlats till sex medverkande sångare om fyra kvinnor och två män under individuella sånglektioner. Deltagarna har i en variant av crossover design skattat sin dagliga rösthälsa i EASE- självskattningsformulär för friska röster. Testperioden om tre veckor följdes sedan av kvalitativa intervjuer. Resultat visar att även om sångares vardag är komplex, i och med inre och yttre påverkande faktorer, har nedsjungning en upplevd effekt i avseendet förbättrad rösthälsa efter högintensiv sång. Detta gäller särskilt de kvinnliga sångarna som beskriver att nedsjungning bidragit till en mer samlad röst med minskad heshet och svullnad. Vidare rapporteras om större lätthet inför att sjunga i lägre delen av bröstregistret, en mer egaliserad röst och en förbättrad tal- och magstödsteknik tillsammans med större lätthet inför påföljande sångpass. Nedsjungning ses också ha skapat ett andrum i vardagen där minskad stress, prestationskrav och resultatinriktning omvänts till en samlad känsla av avslut. Likväl är begrepp som nedsjungning, att sjunga ned, kyla ned, eller att stretcha rösten nya begrepp som rekommenderas att vidare studeras och förmedlas till elever och studenter, framför allt då föreliggande studies resultat visar tydliga attitydskillnader avseende rösthälsa och röstvård emellan de olika könen. / This is a study regarding singers' experiences of a vocal-cool down routine preceded with a heavy vocal load. The study is mainly based on a qualitative approach with quantitative elements. At first individual singing lessons where held, whereas specifically designed vocal-cool down exercises were taught to six participating singers; four women and two men. With a modification of a crossover design the singers in this study have estimated their daily voice health in the Evaluation of the Ability to Sing Easily survey (EASE). After a three week period of tests the singers were interviewed. The result of this study shows that even if singers' everyday lives are complex due to internal and external factors, vocal- cool down where perceived as an improvement of voice health. It is mainly the female singers' that describes an increased vocal well-being, with less hoarseness and swollen vocal folds after a heavy vocal load, followed by a vocal -cool down routine. Furthermore a greater sense of ease was reported in terms of transitions between registers in the singing voice, where fatigue in the surrounding muscles also decreased alongside with a positive impact on the speaking voice, reaching lower notes in chest register and extended diaphragm breathing. The vocal cool-down routine itself also gave an unexpected finding in terms of being contemplative and relaxing for the singers; creating a breathing space in everyday life where stress, performance anxiety and other concerns where easier to let go of, with an overall feeling of closure. Vocal cool down, cooling down the voice, vocal stretch, or warming down your voice are all relatively new concepts that are recommended to be studied further, spread and taught to students and pupils, - especially as the result in this study indicates clear differences in attitudes regarding voice health in-between the male and female genders.
