Gnaphalio uliginosi-eleocharitetum acicularis Passarge 1999, new plant community in Poland
2017
Zbiorniki wodne są bardzo cennymi miejscami florystycznymi w Polsce. Wśród nich najważniejsze dla zachowania różnorodności biologicznej flory są stawy rybne. Długookresowy proces oddziaływania ludzkiego na tego typu siedliska powodował zakłócenia w ich równowadze biologicznej. Zmiany w systemie wodnym, rozwój przemysłowy i chemizacja rolnictwa, zwłaszcza w okresie ostatnich dwóch stuleci, doprowadziły do zaniku wielu gatunków roślin oraz zbiorowisk roślinnych. Zespół Gnaphalio uliginosi-Eleocharitetum acicularis Passarge 1999 z klasy Isoëto-Nanojuncetea Br.-Bl. et Tx. 1943, po raz pierwszy został opisany w Niemczech. Rośnie na piaszczystych lub mulistych brzegach rzek, starorzeczach i w sta…
A BSM hunting guide after Run I
2017
La tesis doctoral tiene como objetivo explorar algunos de los diversos campos de actividad de la física de partículas tras el descubrimiento del bosón de Higgs en el LHC. Por ello, incluye trabajo tanto en extensiones del Modelo Estándar (SM) como la Supersimetría (SUSY), la formación de la estructura del universo tras el periodo de inflación primigenia y un modelo para neutrinos dextrógiros (RH-neutrino). Todo ello ha sido analizado con un cariz fenomenológico, para que la teoría no se despegue demasiado de los diferentes experimentos que pueden confirmarla o refutarla. En cuanto a SUSY se refiere, se decidió hacer un estudio fenomenológico del sector de Higgs de MSSM (modelo con un número…
Antimicrobial and Antioxidant Activities of Coumarins from the Roots of Ferulago campestris (Apiaceae)
2009
We report the isolation of several coumarins and the stereochemical assessment of some pyranocoumarins, as well as the antibacterial and antioxidant activities of the three most abundant ones (grandivittin, agasyllin and aegelinol benzoate) isolated from the roots of Ferulago campestris collected in Sicily and of the hydrolysis product (aegelinol). Aegelinol and agasyllin showed antibacterial activity against nine ATCC and the same clinically isolated Gram-positive and Gram-negative bacterial strains. At a concentration between 16 and 125 μg/mL both coumarins showed a significant antibacterial effect against both Gram-negative and Gram-positive bacteria. In particular the ATCC strains Staph…
Spin-multipole nuclear matrix elements in the pn quasiparticle random-phase approximation: Implications for β and ββ half-lives
2017
Half-lives for 148 potentially measurable 2nd-, 3rd-, 4th-, 5th-, 6th-, and 7th-forbidden unique beta transitions are predicted. To achieve this, the ratio of the nuclear matrix elements (NMEs), calculated by the proton-neutron quasiparticle random-phase approximation (pnQRPA), MpnQRPA, and a two-quasiparticle (two-qp) model, Mqp, is studied and compared with earlier calculations for the allowed Gamow-Teller (GT) 1+ and first-forbidden spin-dipole (SD) 2− transitions. The present calculations are done using realistic single-particle model spaces and G-matrix based microscopic two-body interactions. In terms of the ratio k = MpnQRPA/Mqp the studied decays fall into two groups: for GROUP 1, w…
Identification of Russian accented Finnish by native and non-native listeners with and without Finnish proficiency
2018

 
 
 The study focuses on how different groups of listeners, that is native Finnish speakers (n = 18), non-native learners of Finnish (n = 12) and non-native non-learners of Finnish (n = 18), judge samples (n = 80) of Russian accented Finnish in an auditory experiment. The samples are read-aloud phrases of three Finnish speakers and three L1 Russian beginner learners of Finnish who were recorded three times at six-month intervals during their residence in Finland. The results show that the listener groups differ significantly from each other in the ability to identify the Russian accented samples. In addition, all the listener groups reported to have paid more attention to p…
Striving for mutual understanding : native English speakers' views on speech modifications in intercultural encounters
2016
”Foreigner talk” -nimistä ilmiötä on aikaisemmin tutkittu melko laajaltikin eri näkökulmien kautta. Suurin osa tutkimuksesta on tehty 1980-luvulla, jonka jälkeen termin käyttö näyttää hiljalleen vähentyneen. ”Foreigner talk” tarkoittaa muokattua kieltä, jonka tarkoitus on tehdä puheesta ymmärrettävämpää henkilölle, jonka kompetenssi kohdekielessä ei ole toisen puhujan kanssa syystä tai toisesta samalla tasolla: kyseessä voivat olla esimerkiksi kieltä äidinkielenään puhuva henkilö ja kieltä vieraana kielenä puhuva henkilö. Aivan viime aikoina ilmiö näyttää nouseen taas suosioon tutkimuskohteena etenkin osana työympäristöä, jossa kansainväliset kohtaamiset ovat monelle arkipäivää. Siitä huoli…
Bimodal sill emplacement from an inhomogeneous source: a case study of olivine-gabbronorite and diabase with Ni-Cu sulphides in a sill within Permian…
2009
A small outcrop of mafic rocks, located between the Permian-Triassic sediments of the Cenozoic tectonic unit of the Maghrebian chain in Western Sicily, is an olistolith made up of olivine gabbronorite within diabase. Textures, microprobe analyses, and major and trace element geochemistry confirm the co-genetic nature of the various rocks: the gabbronorite is the result of olivine and orthopyroxene accumulation, with interstitial clinopyroxene and plagioclase, in a framework of a gabbrodioritic diabase. At least two stages of magmatic crystallisation during ascent in the continental crust are described, on the basis of reconstructed conditions of T, P and XH2O. The primitive magma was recons…
The gallium anomaly revisited
2019
The gallium anomaly, i.e. the missing electron-neutrino flux from $^{37}$Ar and $^{51}$Cr electron-capture decays as measured by the GALLEX and SAGE solar-neutrino detectors, has been among us already for about two decades. We present here a new estimate of the significance of this anomaly based on cross-section calculations using nuclear shell-model wave functions obtained by exploiting recently developed two-nucleon interactions. The gallium anomaly of the GALLEX and SAGE experiments is found to be smaller than that obtained in previous evaluations, decreasing the significance from 3.0σ to 2.3σ. This result is compatible with the recent indication in favor of short-baseline ν¯e disappeara…
Supramolecular Hydro- and Ionogels: A Study of Their Properties and Antibacterial Activity.
2017
Diimidazolium-based organic salts, bearing peptides or amino acids as anions have been synthesised and tested for their gelling ability in biocompatible solvents. These low molecular weight salts were successfully used as gelators in phosphate buffered saline (PBS) solution and ionic liquids. Then, the properties of the obtained soft materials were analysed in terms of melting temperature and gel strength as accounted for by rheological investigations. The gel-phase formation was studied by using UV/Vis and resonance light scattering measurements, whereas the morphology of the soft materials was analysed by using polarised optical microscopy and scanning electron microscopy. To get informat…
Recent results from Borexino and the first real time measure of solar pp neutrinos
2014
International audience; The Borexino detector was built starting from 1996 in the underground hall C of Gran Sasso National Laboratory (LNGS) in Italy under about 1400 m of rock (3800 m.w.e) and it is mostly aimed to the study in real-time of the low-energy solar neutrinos.Since the beginning of data taking, in May 2007, the unprecedented detector radio-purity made the performances of the detector unique: a milestone has been very recently achieved with the measurement of solar pp neutrino flux, providing the first direct observation in real time of the key fusion reaction powering the Sun.In this contribution the most important Borexino achievements to the fields of solar, geo-neutrino and…
