Influence of torrefaction pretreatment on the pyrolysis of Eucalyptus clone: A study on kinetics, reaction mechanism and heat flow
2016
Abstract The adverse nature of biomass requires specific pretreatment processes to better utilize it in bioenergy applications, and torrefaction is one of the most recognized thermal pretreatment methods. In this regard, we studied the effect of torrefaction pretreatment on kinetics, reaction mechanism and heat flow during the pyrolysis of biomass by making a comparative analysis between the pyrolysis of dried and torrefied Eucalyptus wood. Torrefied biomass was produced at three temperatures, namely 250, 275 and 300 °C. Pyrolysis was performed at 700 °C. The char yield during pyrolysis increased from 22.39 percent to 36.34 percent when the torrefaction temperature was increased from 250 to…
Diurnal Cycle Relationships between Passive Fluorescence, PRI and NPQ of Vegetation in a Controlled Stress Experiment
2017
In order to estimate vegetation photosynthesis from remote sensing observations; some critical parameters need to be quantified. From all absorbed light; the plant needs to release any excess that is not used for photosynthesis; by non-photochemical quenching; by fluorescence emission and unregulated thermal dissipation. Non-photochemical quenching (NPQ) processes are controlled photoprotective mechanisms which; once activated; strongly control the dynamics of photochemical efficiency. With illumination conditions increasing and decreasing during a diurnal cycle; photoprotection mechanisms needs to change accordingly. The goal of this work is to quantify dynamic NPQ; measured from active fl…

Taming of the Rake: From a Man about Town to a Man at Home in "The Tenant Of Wildfell Hall" by Anne Brontë
2015
In „The Tenant of Wildfell Hall” Anne Brontë considers one of the most burning questions of the Victorian period, i.e. the problem of male domestic violence. The novel contributed to the public debate on the defects of the legal system which discriminated against women and made them totally dependent on their fathers and husbands. However, the writer’s diagnosis of the social issue does not focus on the formal aspects only, as she believed that political action should be accompanied by a farreaching reconceptualisation of nineteenth-century models of femininity and masculinity. Brontë suggests that legal reform is not enough to eliminate such pathologies as marital abuse. She tries to disma…
Model społeczeństwa a założenia Specjalnej Strefy Demograficznej
2016
Założenia opolskiej Specjalnej Strefy Demograficznej odwołują się do strukturalno-systemowych teorii społeczeństwa. Stan katastrofy demograficznej wymaga, moim zdaniem, przeprowadzenia reprezentatywnych badań empirycznych wśród młodego pokolenia, opracowania socjologicznego studium i uzupełnienia teoretycznych założeń Specjalnej Strefy Demograficznej w regionie opolskim.
Studying Gamow-Teller transitions and the assignment of isomeric and ground states at $N=50$
2022
Direct mass measurements of neutron-deficient nuclides around the N=50 shell closure below $^{100}$Sn were performed at the FRS Ion Catcher (FRS-IC) at GSI, Germany. The nuclei were produced by projectile fragmentation of $^{124}$Xe, separated in the fragment separator FRS and delivered to the FRS-IC. The masses of 14 ground states and two isomers were measured with relative mass uncertainties down to 1×10−7 using the multiple-reflection time-of-flight mass spectrometer of the FRS-IC, including the first direct mass measurements of $^{98}$Cd and $^{97}$Rh. A new QEC=5437±67 keV was obtained for $^{98}$Cd, resulting in a summed Gamow-Teller (GT) strength for the five observed transitions (0+…
Prometheus-leirit kasvun areenana
2019
Artikkelissa käsitellään Prometheus-leirien vaikutusta leiriläisiin. Tutkimus on monimenetelmäinen aineistolähtöinen tutkimus ja asettuu nuorisotutkimuksen monitieteiseen kenttään. Tulkinnat pohjautuvat leirien osallistujilta leirikesän 2017 aikana ja jälkeen koottuihin kirjoitelmiin ja videopäiväkirjoihin sekä verkkokyselyyn. Tutkimusote korostaa leiriläisten omia tulkintoja. Jäsentävänä käsitteenä käytetään maailmankuvien kehitystä. Aineistossa rakentuu tarina itseymmärryksen syvenemisestä ja leirin vaikuttavuuden prosessinomaisuudesta. Leirien vaikutus näyttää myös keskittyvän pikemminkin sosiaalisiin taitoihin kuin tietoon. peerReviewed

Are gut hormones responsible for the decrease of appetitive behaviour for sweet and fatty foods after gastric bypass surgery?
2013
WOS: 000321389200211; International audience; Introduction: Gastric bypass surgery (RYGB) decreases preference for sweet and fatty foods, but the underlying mechanism is not known. This study aimed to investigate the role of the exaggerated satiety gut hormone release on appetitive reward of sweet and fatty taste after RYGB. Method: 13 patients that have undergone previous RYGB surgery (>6 months) and 13 normal weight controls participated in a double-blind placebo-controlled trial comparing the effect of subcutaneous injections of somatostatin analogue (octreotide) which blocks satiety gut hormone responses, and saline (control) on the appetitive reward value of sweet-fat candies. Appetiti…
