Photochemical transformation of dissolved organic matter in aquatic environment - From a boreal lake and Baltic Sea to global coastal ocean

Hanna Aarnos

As dissolved organic matter (DOM) constitutes a vast reservoir of carbon and nutrients in lakes, rivers and ocean, it plays an important role in the global carbon and nutrient cycles. Only a part of DOM is directly biologically utilizable by bacteria, but solar radiation induced photochemical reactions may mineralize DOM to inorganic forms such as dissolved inorganic carbon (DIC) and amm...

Kenen Aleksi, sen Helsinki - Kluuvin kävelykatutaistelut 1968 - 2003

Janne Viitamies

Yhtenä tutkimukseni johtopäätöksenä on, että Helsingin kävelykeskusta laajenee, kun autoliikenteen nopeutta hillitään ja jalankulkutilaa lisätään, mutta ei siten, että autoilu pyrittäisiin täysin kieltämään. Kaupunki määritteli jalankulkemisen ydinkeskustan tärkeimmäksi kulkumuodoksi jo 1970-luvun alussa. Silti Kluuvin nykyinen kävelykeskusta muodostui ristiriitojen jälkeen vasta 1990-lu...

Discovery of small molecule modulators of Ras superfamily proteins : Studies of MgcRacGAP and Ras

Arjan van Adrichem

Small guanosine triphosphatases (GTPases) are a family of low molecular weight guanosine diphosphate (GDP)-/guanosine triphosphate (GTP)- binding proteins that act as molecular switches , regulating key cellular processes, such as cell proliferation and differentiation. The activity of small GTPases is controlled by guanine nucleotide exchange factors (GEFs), which facilitate nucleotide ...

Perinatal regulation of lung liquid absorption in pulmonary adaptation in newborn infants

Cecilia Janér

Respiratory distress is a major contributor to morbidity in newborn infants. Insufficient clearance of lung liquid at birth causes maladaptation (transient tachypnea of the newborn, TTN) primarily in late preterm (delivery at 34 0/7 to 36 6/7 gestational weeks) and term infants. In small preterm infants excess lung liquid further complicates respiratory distress syndrome (RDS) caused by ...
