Turbinkretspump system - Kraftvärmeverket i Borås
The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.
"Hjälper mig att förstår vad text handlar om" : en undersökning av två skolexterna läxläsningsverksamheter

Finansiella värderingsmodeller : En empirisk studie
This study tests two financial valuation models empirically by valuing three stocks from three industries, with the purpose of studying how well valuation models work empirically and to make a forecast. The models which will be tested are residual income valuation and discounted cash flow. Nine stocks will be picked strategically from the Swedish stock market and additional analysis will follow in the analysis chapter.Based on analysis and valuation, the commodities industry has decent valuation as the healthcare industry is undervalued thanks to the high valuation of AZN. The energy industry has low value due to the capital intensive nature of the industry. When it comes to the models and their practical implementation, DCF has been the most problematic to apply empirically whereas RIV was better but it still shows extreme values, which teaches the student the clear difference between theory and empiri..

Kombinationsträningseffekter på fysiologiska egenskaper relevanta för handbollsprestation på elitnivå. : En experimentell interventionsstudie på manliga elithandbollsspelare under tävlingssäsong.
Syfte och frågeställningar: Syftet med denna studie var att undersöka de fysiologiska effekterna av kombinationsträning, innefattande styrketräning, contrast complex training (CCT) kombinerat med intervallträning i form av upprepade kortare sprintar (ca 6 s) (RSE) eller längre (30 s) högintensiva intervaller (HIIT) hos handbollsspelare i herrelit, under tävlingssäsong.Metod: Under 12 veckor, i tävlingssäsong, genomförde 15 elithandbollsherrar, utöver sin vanliga handbollsträning antingen RSE (n=8) bestående av 10 repetitioner av shuttle sprintar (2 x 15 m) med start varje minut och med passiv vila eller HIIT (n=7) bestående av 5 reps av 30-s all-out sprintar med riktningsförändringar. Båda grupperna genomförde ocksåCCT bestående av 3 set med 3 övningar (3 x knäböj 90 % av 1RM, 6 x jump squat med 50 % av kroppsvikten, 6 x dropp jump från 30 cm Pre- och posttesterna inkluderade jump squat (JS) (RFD (Ns/kg)), 5 jump for distance test (5JT) (m), 30m sprint (5m (s), 20-30m (m/s), repeated shuttle sprint ability test (RSSA) (RSA Bäst, Sämst, Tot (s) samt beräknat trötthetindexFI (%), Sdec (%)), 1 RM knäböj (koncentrisk) (kg/kg kroppsvikt), Yo-Yo intermittent recovery test (YYIRT 1)(m) and maximal syreupptagningstest (VO2max) (l O2/min, ml·kg-0.75·min-1). Resultat: Båda grupperna ökade signifikant maxstyrkan i knäböj, RSE gruppen (8,8 %) mer än HITT (7,4 %) (p<0.01). I motsats visade HIIT gruppen större förbättringar i rate of force development (RFD) (63,3 %) än RSE (56,3 %) (p<0,05). VO2max ökade signifikant och likartat i båda grupperna (~2%).
