Studies of the B0s-B0sbar system in the CMS experiment at the LHC

Giacomo Fedi

The B0s-B0sbar system was investigated using the J/ψ(μ+μ−)φ(K+K−) decay channel. Using 2010 CMS data, corresponding to an integrated luminosity of 40 1/pb, the B0s invariant mass peak was reconstructed and the B0s differential cross section as a function of its transverse momentum and rapidity were measured. Using 2011 CMS data, corresponding to an integrated luminosity of 5 1/fb, the di...

Specific probiotics in the upper respiratory tract: colonization, efficacy and safety : with a focus on Lactobacillus rhamnosus GG

Laura Tapiovaara

Upper respiratory infections are among the most common ailments in humans. Evidence for mechanisms suggests that specific probiotic bacteria could reduce the risk and symptoms of these infections. However, the clinical evidence of probiotics in the upper respiratory tract, especially when colonization and the etiological effects are considered, is sparse. In addition, the safety of probi...

Regulation of Podocyte apoptosis in Diabetic Kidney Disease - Role of SHIP2, PDK1 and CDK2

Pauliina Saurus

Background: Diabetic nephropathy (DN) is a renal complication of diabetes and a common cause of end-stage renal disease (ESRD). DN presents in its earliest stage with low levels of albumin in the urine (microalbuminuria) and develops into overt albuminuria as the disease progresses. Podocyte loss due to detachment or apoptosis has a central role in the pathogenesis of DN, but the mechani...

Inelastic X-ray scattering spectroscopy of small molecules and their radiation chemistry

Juho Inkinen

Non-resonant inelastic x-ray scattering can provide information on various atomic-scale properties and phenomena by probing the spectrum of electronic excitations. The technique allows bulk-sensitive measurements and relatively freely tunable sample conditions even for excitations with energies in the soft x-ray range. Also non-dipolar excitations are accessible by virtue of the ability ...

Enhancing children's participation in early childhood education through participatory pedagogy

Jonna Kangas

Children's participation in early childhood education has raised concern and discussion in the international researches lately. Young children have been considered to have lack of participation experiences in early education settings because of institutional policies, social understanding about childhood and perspectives of educators (Bae, 2009; Emilson and Folkesson, 2006; Smith, 2002)....

Transnational Governance by Numbers : Rankings as Mechanisms of Governing

Ossi Piironen

Quantitative knowledge plays an increasing role in transnational governance, even when not explicitly part of formal processes of decision making. This study consists of five research articles that individually and together deal with the subtle ways by which socio-political quantification influence governance and politics. Rather than looking at the direct impact a specific ranking has o...

On Heavy-tailed Risks with Applications to Insurance and Finance

Jaakko Lehtomaa

This book is about heavy-tailed random variables and the phenomena they induce to mathematical models. It has become clear that the classical models employing light-tailed variables have an inherent tendency to underestimate the magnitude of extremal events. Recent developments in the financial world (financial crises) suggest that such shortcomings are not merely theoretical curiosities...

Towards more consistent estimates of methane fluxes by the eddy covariance technique

Olli Peltola

Methane (CH4) is a strong greenhouse gas and its surface mixing ratio has increased by 150 % since the pre-industrial era. The aggregated atmospheric CH4 budget is relatively well-constrained, however the contribution of different sources/sinks to the overall budget is not. The exchange of matter and energy between the atmosphere and different ecosystems can be studied with eddy covarian...
