Separation of atomic and molecular ions by ion mobility with an RF carpet
2021
Gas-filled stopping cells are used at accelerator laboratories for the thermalization of high-energy radioactive ion beams. Common challenges of many stopping cells are a high molecular background of extracted ions and limitations of extraction efficiency due to space-charge effects. At the FRS Ion Catcher at GSI, a new technique for removal of ionized molecules prior to their extraction out of the stopping cell has been developed. This technique utilizes the RF carpet for the separation of atomic ions from molecular contaminant ions through their difference in ion mobility. Results from the successful implementation and test during an experiment with a 600~MeV/u $^{124}$Xe primary beam are…
Reformaation jäljet tämän päivän yhteiskunnassa
2016
Vuotta 2017 voi hyvällä syyllä kutsua sukupolvemme suurimmaksi merkkivuodeksi ja myös lähiaikojen merkittävimmäksi mahdollisuudeksi reflektoida kansallista identiteettiä Suomessa. Tuolloin vietetään Suomen itsenäisyyden 100-vuotisjuhlaa ja samana vuonna tulee kuluneeksi myös 500 vuotta reformaation alkamisesta Saksan Wittenbergissä. Näitä merkkivuosia huomioidaan Suomessa myös akateemisesti monin eri tavoin: sekä Suomen itsenäisyyttä että reformaatiota koskevia kirjahankkeita ja tapahtumajärjestelyitä on meneillään useita. nonPeerReviewed
Biofiltration of airborne VOCs with green wall systems : microbial and chemical dynamics
2018
Botanical air filtration is a promising technology for reducing indoor air contaminants, but the underlying mechanisms need better understanding. Here, we made a set of chamber fumigation experiments of up to 16 weeks of duration, to study the filtration efficiencies for seven volatile organic compounds (VOCs; decane, toluene, 2‐ethylhexanol, α‐pinene, octane, benzene, and xylene) and to monitor microbial dynamics in simulated green wall systems. Biofiltration functioned on sub‐ppm VOC levels without concentration‐dependence. Airflow through the growth medium was needed for efficient removal of chemically diverse VOCs, and the use of optimized commercial growth medium further improved the e…
Efficiency of Daphnia magna in removal of green microalgae cultivated in Nordic recirculating aquaculture system wastewater
2020
The increase of global aquaculture production has boosted the development of recirculating aquaculture systems not only because they reduce water use but also provide opportunities for waste management and the use of released nutrients. The dissolved nutrients can be efficiently removed from recirculating aquaculture system wastewater by microalgae, and microalgae can be harvested from the wastewater with low costs by zooplankton such as Daphnia. The purpose of this study was to evaluate the feasibility of using microalgae and Daphnia for bioremediation of recirculating aquaculture system wastewater in Nordic conditions. We evaluated the growth and filtration efficiency of the waterflea Dap…

Limits of Power. Clerical Appointment as Part of Domestic Policy in Sweden after the Reformation, 1560–1611
2015
Abstract This article examines state-church relations in Sweden by analysing clerical appointment processes in the latter part of the 16th century. The aim is to ascertain whether the king of Sweden could appoint pastors independently, and if not, with whom he was compelled to share the power. Earlier studies argue that the power of the king grew due to the reformation. First, this article examines the number of clerical appointments that were made in the period 1560-1611. The results reveal a remarkable annual variation in the number of clerical appointments. Second, the timing and share of clerical appointments made by the king are studied. The number of appointments made by the king is v…
Environmental remediation using nanomaterial as adsorbents for emerging micropollutants
2023
Water shortage and scarcity are issues of global concern. Water pollution caused by organic micropollutants further aggravates the problem, by rendering an already scarce resource unfit for human consumption. The existing conventional wastewater treatment methods and infrastructure were not designed to eliminate micropollutants. Therefore, their inefficiencies call for modern methods for removing emerging micropollutant residues such as Active Pharmaceutical Ingredients (APIs), Endocrine Disrupting Compounds (EDCs), personal care products and pesticides. The use of nanomaterials, for the abatement of micropollutants in water is gaining traction in recent years, due to the abundance of susta…
