Convergent results from experimental and theoretical DFT studies of the intramolecular rearrangement of Z-hydrazones of 3-acetyl-1,2,4-oxadiazoles

2004

A combined kinetic and theoretical study of the monocyclic rearrangements of heterocycles (MRH) has been carried out. The interconversion of the Z-hydrazone of 3-benzoyl-5-phenyl-1,2,4-oxadiazole into the corresponding triazole has been experimentally investigated in dioxane/water in the pS(+) range 5.5(5)-13.9. The uncatalyzed region has been examined at the DFT level using a model system formed by the Z-hydrazone of 3-formyl-1,2,4-oxadiazole and one or two water molecules. The environmental effect of the solvent has been emulated using a continuum model (COSMO) approach. The kinetic data suggest a concerted process where the magnitude of the activation barrier is determined by the interpl…

Potential and challenges in home care service process optimization : a route optimization approach

2016

Aging of the population is an increasing problem in many countries, including Finland, and it poses a challenge to public services such as home care. Vehicle routing optimization (VRP) type optimization solutions are one possible way to decrease the time required for planning home visits and driving to customer addresses, as well as decreasing transportation costs. Although VRP optimization is widely and succesfully applied to commercial and industrial logistics, the home care is a relatively new application area for it. This thesis examines what kind of distance and time savings would be possible to achieve if daily home care operations are optimized in the similar manner as typical VRP op…

Structural analysis of two foldamer-type oligoamides – the effect of hydrogen bonding on solvate formation, crystal structures and molecular conforma…

2012

Author's Final draft The crystal structures and molecular conformations of two foldamer-type oligoamides were analyzed. One polymorphic form and seven solvates were found for N¹,N³-bis(2-benzamidophenyl)benzene-1,3-dicarboxamide (the benzene variant), and two polymorphic forms and six solvates for N²,N⁶-bis(2-benzamidophenyl)pyridine-2,6-dicarboxamide (the pyridine variant). Three crystal structures of the benzene variant and seven structures of the pyridine variant were solved using single crystal X-ray diffraction. The crystal structures showed that the different modes of intramolecular hydrogen bonding strongly affect the conformation and folding of the molecules, which is most evidently…

Relational dialectics in intercultural couples' relationships

2012

The main purpose of this study is to describe and to understand the intercultural couples’ relationships in Finland from the relational-dialectics perspective by Baxter and Montgomery (1996). Following the interpretive research tradition, in this qualitative study, data were collected from 18 heterosexual intercultural couples (36 persons), utilizing the multi-method approach. The multi-method approach in this study includes theme interviews (5 couples), concept map interviews (six couples) and e-mail interviews (seven couples). The data were analyzed following an inductive content analysis approach. The intercultural couples in this study experienced internal and external dialectics, relat…

Latvijas darba tirgus analīze

2021

Darbs “ Latvijas darba tirgus analīze” aplūko darba tirgus situāciju Latvijā kopumā no 1990.-2020. gadam. Darba mērķis ir izanalizēt darbaspēka pieprasījumu un piedāvājumu ietekmējošus faktorus un to attīstības tendences. Darbā izmantotie statistiskie dati pētīti ar dažādam metodēm. Pēdējos gados Latvijas darba tirgū vērojami neiepriecinošie demogrāfiskie procesi - iedzīvotāju skaita dabiskā samazināšanās, sabiedrības novecošanās, kā arī emigrācija, kas negatīvi ietekmē darbaspēka piedāvājumu, kad visās tautsaimniecības nozarēs vērojams darbaspēka pieprasījuma pieaugums. Vienlaicīgi uz demogrāfiskās slodzes pieauguma fona, iedzīvotāju vidū pieaug personu skaits ar augstāko izglītību, ka arī…

Fabrication of DNA origami lattice on silicon surface for DNA-assisted lithography

2022

Metamaterials obtain new properties from having metallized nanoscale features that are often arranged in repeating patterns. In particular, there is a need to create metasurfaces with a negative refractive index. As nanoscale fabrication using conventional top-down methods can be both difficult and time-consuming, bottom-up techniques have gained growing interest. Especially, the DNA origami method can be utilized to assemble lattices with nanoscale features on 2D surfaces, which can then be metallized using DNA-assisted lithography (DALI). This thesis provides a full study of the DNA origami fishnet lattice assembly kinetics and optimization of lattice order on a silicon surface using liqu…

What Academic Factors Influence Satisfaction With Clinical Practice in Nursing Students? Regressions vs. fsQCA

2020

Clinical practices are considered one of the cornerstones in nurses' education. This study provides a framework to determine how factors in the academic environment, influence nursing student's satisfaction with their practices. A cross-sectional analytical study was conducted in a convenience sample of 574 nursing students at a private university in Valencia, during the 2016/2017 academic year, 79% (456) were women. Two statistical methodologies were used for data analysis: hierarchical regression models (HRM) and fuzzy sets qualitative comparative analysis (fsQCA). The HRM indicate that the students' mean score influences all dimensions of satisfaction. Furthermore, in the fsQCA, the type…
