Nyfinlandssvenskarna : språklig identitet hos invandrare som integrerat sig i det finska samhället på svenska

2014

Tutkimuksen tarkoituksena on saada tarkempaa tietoa maahanmuuttajien kielellisestä identiteetistä. Keskityn tutkimuksessani maahanmuuttajiin, jotka ovat oppineet valtakunnallisen vähemmistökielen ruotsin, joka on heidän sijoituspaikkakunnallaan enemmistökielen asemassa. Tutkimuksen empiirinen materiaali koostuu teemahaastatteluista. Haastateltavina olleet 5 maahanmuuttajaa (iältään 20 – 54-vuotiaita) osallistuivat henkilökohtaisiin teemahaastatteluihin asuin tai työpaikkakunnallaan. Kaksi haastateltavista on tullut Suomeen pakolaisena 1990-luvulla, 2 perhesyistä ja 1 työnantajan lähettämänä. Erilaiset taustat sekä maassaoloaikojen eroavaisuudet (3-22 vuotta) antavat mahdollisuuden tarkastel…

Vibrational Spectroscopy

2015

The molecular information provided by the vibrational spectra obtained by both absorption in the near-infrared and middle-infrared range and Raman dispersion has been critically evaluated to obtain specific information for the authentication of protected designation of origin foods and other food geographical indications. The literature in this field has been updated and the capability of the vibrational spectra to provide discrimination between foods produced in different areas and by using different processes are also discussed.

Methods for the vibrational spectroscopy analysis of beers

2009

The main possibilities and drawbacks of vibrational spectroscopy techniques, infrared (both in the middle and near infrared ranges) and Raman, for the analysis of beers have been reviewed taking into consideration methods proposed in the scientific literature for the determination of as many as possible compounds and parameters of beers. Details about the procedures available and comments on the future developments in this field have been based on the experience of authors and extended checking of the characteristics of the procedures published till now.

High-resolution spectroscopy and analysis of the ν4 band of 80SeF6

2001

Abstract The Fourier-transform spectrum of the ν4 bending region of 80 SeF 6 around 435 cm −1 has been recorded at a temperature of 217 K with a resolution of 2.3×10 −3 cm −1 . This fundamental has been analyzed using the set of programs called highly spherical top data system (HTDS). Altogether 958 transitions were assigned and fitted with an rms of 0.0003 cm −1 . The effective Hamiltonian was developed up to the fourth order. Parameters and simulations are presented. The ν4 band center is located at 435.099 cm −1 .

Biomass estimator for NIR image with a few additional spectral band images taken from light UAS

2012

A novel way to produce biomass estimation will offer possibilities for precision farming. Fertilizer prediction maps can be made based on accurate biomass estimation generated by a novel biomass estimator. By using this knowledge, a variable rate amount of fertilizers can be applied during the growing season. The innovation consists of light UAS, a high spatial resolution camera, and VTT's novel spectral camera. A few properly selected spectral wavelengths with NIR images and point clouds extracted by automatic image matching have been used in the estimation. The spectral wavelengths were chosen from green, red, and NIR channels.

Detecting explosive substances by the IR spectrography

2014

Fast and safe detection methods of explosive substances are needed both before and after actualized explosions. This article presents an experiment of the detection of three selected explosives by the ATR FTIR spectrometer and by three different IR hyperspectral imaging devices. The IR spectrometers give accurate analyzing results, whereas hyperspectral imagers can detect and analyze desired samples without touching the unidentified target at all. In the controlled explosion experiment TNT, dynamite and PENO were at first analyzed as pure substances with the ATR FTIR spectrometer and with VNIR, SWIR and MWIR cameras. After three controlled explosions also the residues of TNT, dynamite and P…

The challenges of analysing blood stains with hyperspectral imaging

2014

Hyperspectral imaging is a potential noninvasive technology for detecting, separating and identifying various substances. In the forensic and military medicine and other CBRNE related use it could be a potential method for analyzing blood and for scanning other human based fluids. For example, it would be valuable to easily detect whether some traces of blood are from one or more persons or if there are some irrelevant substances or anomalies in the blood. This article represents an experiment of separating four persons' blood stains on a white cotton fabric with a SWIR hyperspectral camera and FT-NIR spectrometer. Each tested sample includes standardized 75 _l of 100 % blood. The results s…

One-pot synthesis and characterization of subnanometre-size benzotriazolate protected copper clusters

2012

A simple one-pot method for the preparation of subnanometre-size benzotriazolate (BTA) protected copper clusters, Cu(n)BTA(m), is reported. The clusters were analyzed by optical and infrared spectroscopy, mass spectrometry and transmission electron microscopy together with computational methods. We suggest a structural motif where the copper core of the Cu(n)BTA(m) clusters is protected by BTA-Cu(i)-BTA units.

Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia

2018

The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
