Jet shape modification in Pb-Pb collisions at √S[sub]N[sub]N= 2.76 TeV using two-particle correlations

2018

This thesis focuses on two separate topics. The first topic concerns the upgrade of the Time Projection Chamber (TPC) detector of the ALICE experiment. The upgrade will take place during the second Long Shutdown (2019-2020). The part of the upgrade I participated in was the replacement of the detector’s current readout electronics with Gas Electron Multiplier (GEM) foils. This change would allow for the continuous readout of the data, resulting in a hundredfold increase in the amount of data the ALICE experiment can process, as the TPC is the central tracking detector. I was involved in the Quality Assurance (QA) of these GEM foils. The advanced QA procedure consists of three measurements, a…

The Most Invisible Maternal Experience? Analysing How Maternal Regret Is Discussed in Finland

2021

AbstractIn Finland, becoming a mother is often constructed as an individual choice that ultimately leads to personal fulfilment and happiness, despite the occasional ‘negative’ feelings associated with motherhood such as exhaustion, frustration and tiredness. In this cultural atmosphere, maternal regret continues to be a subject that is hidden, forbidden and rarely scrutinised. It is perhaps surprising that in one of the world’s most gender egalitarian countries, which is also perceived to be one of the best countries in which to be a mother, women still testify that motherhood is limited to survival. We argue that, somewhat paradoxically, discussing the negative emotions of motherhood migh…

Intervalliharjoittelun ja kestojuoksuharjoittelun vaikutukset maksimaaliseen hapenottokykyyn ja juoksun taloudellisuuteen miehillä ja naisilla

2010

  Wennman, Heini 2009. Intervalliharjoittelun ja kestojuoksuharjoittelun vaikutukset maksimaaliseen hapenottokykyyn ja juoksun taloudellisuuteen miehillä ja naisilla. Liikuntafysiologian kandidaatintutkielma. Liikuntabiologian laitos, Jyväskylän yliopisto, 37. Pitkissä kestävyyssuorituksissa elimistö tuottaa energiaa hiilihydraateista ja rasvoista hapen avulla (McArdle 2001, 165). Pitkän matkan juoksuun vaikuttavat fysiologiset tekijät ovat maksimaalinen hapenottokyky, aerobinen kynnysvauhti, sekä juoksun taloudellisuus. Nämä tekijät voivat selittää henkilöiden välisiä eroja pitkänmatkan juoksusuorituksissa jopa 70 %. Kestävyysjuoksijan tyypillisimpiin harjoitusmuotoihin kuuluvat pitkäkesto…

Dietary acid load and acid-base balance in exercise and health from adolescence to late adulthood

2018

This thesis investigated whether dietary acid load has either short-term (4 to 7 days) or prolonged (12 weeks) effects on acid-base status at rest and during submaximal and maximal aerobic exercise; whether the effects of dietary acid load on acid-base status differ between adolescents, young adults and the elderly, and between men and women; and whether the changes in acid-base balance have a further effect on aerobic exercise performance. These questions were addressed in three different study settings in healthy and recreationally active men and women. In studies 1 and 2, which followed a crossover study design, participants were assigned in randomized order to follow a diet with a low o…

DFT Prediction of Enhanced Reducibility of Monoclinic Zirconia upon Rhodium Deposition

2018

Oxides are an important class of materials and are widely used, for example, as supports in heterogeneous catalysis. In a number of industrial catalytic processes, oxide supports actively participate in chemical transformations by releasing lattice oxygen anions. While this is intuitively understood for reducible oxides, the reducibility of irreducible oxides may be modified via nanoengineering or upon inclusion of foreign species. Our calculations predict that the ability of irreducible monoclinic zirconia to release oxygen improves substantially upon deposition of rhodium. Through a comprehensive screening of Rh/ZrO2 with different size of the rhodium species, we find that a Rh adatom and…

FTIR matrix isolation and theoretical studies of glycolic acid dimers

2018

Glycolic acid (GA) dimers were studied in low temperature argon matrices by means of FTIR spectroscopy. Experimentally, the dimers were produced when monomeric glycolic acid molecules were thermally mobilized upon annealing of argon matrices at 25–35 K. The experimental spectra observed upon annealing indicate the presence of three different dimer structures. Computationally, MP2 and DFT calculations were used to study the potential dimer species in order to scrutinize the possible dimer structures, their energetics and their spectral features. Altogether 27 local minima were found for dimer structures for the three lowest conformers of glycolic acid considered based on previous studies on …

Dioxidomolybdenum(VI) and –tungsten(VI) complexes with tetradentate amino bisphenolates as catalysts for epoxidation

2017

Sixteen molybdenum and tungsten complexes with tripodal or linear tetradentate amino bisphenol ligands were studied as catalysts for the epoxidation of cis-cyclooctene, 1-octene, styrene, limonene and α-terpineol. These complexes can be divided into different categories upon key features, i.e. central metal (Mo versus W), side-arm donor (O versus N), hybridization of the N-donor (pyridine versus amine), ligand geometry (tripodal versus linear diamine) and sterical hindrance (Me versus tert-Bu substituents in the phenol part). All complexes can catalyse selectively the epoxidation of cis-cyclooctene by tert-butylhydroperoxide whereas the activities and selectivities towards other olefins (1-…
