Fourier transform infrared (FT-IR) spectroscopy was applied to characterize the extracellular matrix (ECM) of kidney tumor tissue and normal kidney tissue. Freshly resected tissue samples from 31 patients were pressed on a CaF2 substrate. FT-IR spectra obtained from ECM of tumor tissue exhibit stronger absorption bands in the spectral region from 1000 to 1200 cm−1 and around 1750 cm−1 than those o
Distribution of chemical components in the mixed oxalatic, phosphatic and uratic urinary stones was analysed by means of infrared microspectroscopy. The specular reflection from the surface of the cross-sectioned stones was used for the infrared spectroscopic imaging. It was found that the reflection spectra consist from specular and diffuse reflection components and the former one exhibit Reststr
The silver nanoparticle colloid was used to obtain surface enhanced Raman spectra of Listeria monocytogenes, Salmonela enterica, and Esherichia coli bacteria. The SERS spectra were captured using for excitation the near-infrared (1064 nm) laser radiation with reduced intensity, which ensured the prevention of the fluorescence background as well as photo- and thermal decomposition of the samples. I
Infrared spectra of propanoic acid isolated in the neon and argon matrixes were obtained and studied with the aid of the DFT calculations. The geometric structures of the cyclic and open dimers of PA were elucidated. The calculations predict that among various types of the open dimers only one type with additional hydrogen bond between oxygen of hydroxyl group of a monomer and hydrogen of hydroxyl
Infrared spectra of matrix isolated formic, acetic, propionic, and butyric acids mixed with water were obtained. Combining experimental data and theoretical calculations we were able to assign spectral bands arising due to formation of 1:1 complex between water and title acids. The structure of such complexes was elucidated from theoretical and spectral data for the first time. Alternating decreas
PurposeTo describe demographic and diagnostic profiles in a national cohort of older people with intellectual disability (ID) who were prescribed antipsychotics.MethodsUsing national registers, we identified people with ID who were 55 + years in 2012 (n = 7936), as well as a subcohort with complete information on demographic factors (sex, year of birth, severity of ID, presence of behavior impairm
In this paper we describe present work on multimodal prosody bymeans of simultaneous recordings of articulation and head movements. Earlierwork has explored patterning, usage and machine-learning based detection offocal pitch accents, head beats and eyebrow beats through audiovisual recordings.Kinematic data obtained through articulography allows for more comparableand accurate measurements, as we
The aim of this work is the development of a thermodynamically consistent fully coupled thermo-viscoplastic material model for metals undergoing finite deformations. A multiplicative split of the deformation gradient into a thermal, an elastic and a plastic part is introduced, where isotropic thermal expansion and isochoric plastic deformation are assumed. The model is based on a decomposition of
Den här avhandlingen berör två olika forskningsområden som är relaterade till fysiken för nanosystem. Det första området rör kvantkorrelationer och sammanflätning mellan elektroner i nanosystem, med ett särskilt fokus på hur man kan generera elektronisk orbital sammanflätning på tidsskalor mycket kortare än dekoherenstiden och hur man kan göra detektionen av sammanflätning enklare experimentellt. This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes. The second topic concerns heat
