Euclid preparation XV. Forecasting cosmological constraints for the Euclid and CMB joint analysis
2022
The combination and cross-correlation of the upcoming $Euclid$ data with cosmic microwave background (CMB) measurements is a source of great expectation since it will provide the largest lever arm of epochs, ranging from recombination to structure formation across the entire past light cone. In this work, we present forecasts for the joint analysis of $Euclid$ and CMB data on the cosmological parameters of the standard cosmological model and some of its extensions. This work expands and complements the recently published forecasts based on $Euclid$-specific probes, namely galaxy clustering, weak lensing, and their cross-correlation. With some assumptions on the specifications of current and…
A social and environmental impact assessment of the Crucitas gold mining project in Costa Rica
2014
In 2008 Costa Rica was facing a critical time in its history. A five year mining moratorium had just ended and mining companies were interested in exploring untapped resources in the country. The country was facing important decisions with which development path to take. The Crucitas Mining Project (CMP) was an issue that the whole country had an opinion on; in fact the Constitutional Court of Costa Rica (SALA IV) was debating what to do with the CMP. The purpose of this study was to assist decision makers by providing a well-rounded assessment of the impacts the CMP would have. The goal of this study was to evaluate whether it would be better for Costa Rica to let the mining operation cont…
Effect of a social intervention of choice vs. control on depressive symptoms, melancholy, feeling of loneliness, and perceived togetherness in older …
2016
Objectives: This study examined effects of a social intervention on depressive symptoms, melancholy, loneliness, and perceived togetherness in community-dwelling Finnish older people. Method: Promotion of mental well-being in older people (GoodMood; ISRCTN78426775) was a single-blinded randomized control trial lasting 1.5 years. Two hundred and twenty-three persons aged 75–79 years reporting symptoms of loneliness or melancholy were randomized into intervention and control groups. The intervention group was allowed to choose among supervised exercise, social activity, or personal counseling. Follow-up measurements were conducted at the end of 6-month intervention, and at 3, 6, and 12 months…
Theoretical absorption spectrum of the Ar–CO van der Waals complex
2003
The three-dimensional intermolecular electric dipole moment surface of Ar–CO is calculated at the coupled cluster singles and doubles level of theory with the aug-cc-pVTZ basis set extended with a 3s3p2d1f1g set of midbond functions. Using the rovibrational energies and wave functions of our recent study [J. Chem. Phys. 117, 6562 (2002)], temperature-dependent spectral intensities are evaluated and compared to available experimental data. Based on the theoretical spectrum, alternative assignments of the experimentally observed lines in the fundamental band of CO around 2160 and 2166 cm−1 are suggested. Thomas.Bondo@uv.es
HP-Xe to go: Storage and Transportation of Hyperpolarized 129-Xe
2016
Abstract Recently the spin–lattice relaxation time T 1 of hyperpolarized (HP)- 129 Xe was significantly improved by using uncoated and Rb-free storage vessels of GE180 glass. For these cells, a simple procedure was established to obtain reproducible wall relaxation times of about 18 h. Then the limiting relaxation mechanism in pure Xe is due to the coupling between the nuclear spins and the angular momentum of the Xe–Xe van-der-Waals-molecules. This mechanism can be significantly reduced by using different buffer gases of which CO 2 was discovered to be the most efficient so far. From these values, it was estimated that for a 1:1 mixture of HP-Xe with CO 2 a longitudinal relaxation time of …

Kauppinen, A. 2016. CrossFit Suomen jälkimodernissa liikuntakulttuurissa. CrossFitin rantautuminen, organisoituminen ja laji liikuntamuotona. Liikuntakasvatuksen laitos, Jyväskylän yliopisto. Liikunnan yhteiskuntatieteiden pro gradu -tutkielma, s.85, 2 liitettä. Suomalainen liikuntakulttuuri elää jatkuvassa muutoksen tilassa. Uusi sukupolvi muokkaa perinteisiä liikuntalajeja uudelleen vastaamaan paremmin nykyisiä tarpeitaan. Samalla virtuaalimaailman kehitys tuo kaukaisemmatkin liikuntavaikutteet lähelle. Liikunnalle asetetaan yhä kokonaisvaltaisempia merkityksiä ihmisten arjessa ja yhteiskunnassa. Uusia liikuntalajeja tutkimalla saadaan yhteiskunnallisesti arvokasta tietoa liikunnan muuttu…
Using Blockchain in Digitalizing Enterprise Legacy Systems: An Experience Report
2021
Blockchain technology and distributed ledger technology (DLT) offer a secure, distributed, and tamper-proof way to store and exchange information. However, apart from standard cryptocurrency-based networks, innovations and process improvements based on the blockchain technology have mostly remained on the conceptualizing stage and have not yet reached mass adoption. There is a high demand for practical experiences from developing blockchain and DLT based systems in various domains outside FinTech. This work seeks to contribute to this gap by presenting real-world experiences from developing a proof of concept for automatizing conditional payments in social benefits and healthcare domains. W…
Metallophilic interactions in polymeric group 11 thiols
2016
Three polymeric group 11 transition metal polymers featuring metallophilic interactions were obtained directly via self-assembly of metal ions and 4-pyridinethiol ligands. In the cationic [Cu2(S-pyH)4]n2+ with [ZnCl4]n2− counterion (1) and in the neutral [Ag(S-py) (S-pyH)]n (2) 4-pyridinethiol (S-pyH) and its deprotonated form (S-py) are coordinated through the sulfur atom. Both ligands are acting as bridging ligands linking the metal centers together. In the solid state, the gold(I) polymer [Au(S-pyH)2]Cl (3) consists of the repeating cationic [Au(S-pyH)2]+ units held together by aurophilic interactions. Compound 1 is a zig-zag chain, whereas the metal chains in the structures of 2 and 3 a…
(5R)-5-[(1R)-2,2-Dichloro-1-methylcyclopropyl]-2-methylcyclohex-2-en-1-one
2011
The title compound, C(11)H(14)Cl(2)O, was synthesized by the reaction of a dichloro-methane solution of (R)-carvone and potassium tert-butano-late in the presence of a catalytic amount of benzyl-triethyl-ammonium chloride in chloro-form. The cyclo-hexene ring adopts a half-boat conformation. The cyclo-propyl ring is unsymmetrical, the shortest C-C bond being distal to the alkyl-substituted C atom. The crystal packing is stabilized only by van der Waals inter-actions.
(S)-4-(2-Chloropropan-2-yl)-1-(2,2,2-trichloroethyl)cyclohexene
2011
The title compound, C(11)H(16)Cl(4), was synthesized by the reaction of (1S)-β-pinene with triethyl-amine in the presence of ZnCl(2). The cyclo-hexene ring assumes a half-boat conformation. The crystal packing is governed only by van der Waals inter-actions. The structure, which has been refined in P2(1), presents a striking P2(1)/m pseudosymmetry.
