Comparison of extraction efficiency using ethanol and methanol for the extraction of mycosporin-like amino acids (MAAs) from Palmaria palmata
Mycosporin like amino acids (MAAs) are low molecular weight, water soluble compounds widely distributed in marine organisms specially in seaweed, where they function as natural ultravoilet (UV) protective agents. Due to their strong UV-absorbing properties and antioxidant potential MAAs have gained …

Maahanmuuttopolitiikka Kanadassa ja Suomessa : "We are all immigrants to this place even if we were born here"
Tämän tutkielman tutkimuskohde on maahanmuuttopolitiikka Kanadassa ja Suomessa. Kanada on niin sanottu klassisen siirtolaisuuden maa, jossa siirtolaisuuden perinteet ovat vahvat. Kanada on kuitenkin vienyt maahanmuuttopolitiikkansa vielä paljon pidemmälle vastaanottamalla yhä vuosittain 200 000–200 …
