Kemp elimination: a probe reaction to study ionic liquids properties.
2008
The amino induced elimination of benzisoxazole into the relevant o-cyanophenolate ion (Kemp elimination) has been studied in [bmim][BF 4] solution at 298 K. To have information about the interactions between reactants and ionic liquid, the reaction has been carried out at different temperatures (293-313 K). Several primary, secondary, and tertiary amines have been used to study the effect of amine structure on the reaction rate. The collected data show that the amine structure seems to have a crucial role in determining the reaction rate. Furthermore, as different cation or anion structures of an ionic liquid can significantly affect its properties, the title reaction has been performed in …
Assessment of test-meal induced autonomic arousal in anorexic, bulimic and control females
1998
This study attempted to measure three different physiological responses to food intake in eating disordered subjects. Skin conductance level (SCL), heart rate and electroencephalogram were recorded before, during and after a test-meal in 42 females (14 anorexic inpatients, 10 bulimic outpatients and 18 control subjects). Significant increase in SCL during the meal was found in anorexics only. Pre-meal SCL was lower in bulimics than in controls and anorexics. No changes were found on heart rate or electroencephalogram in all groups of subjects. This suggests that anorexic inpatients may display a measurable arousal when confronted with a meal, whereas bulimic outpatients and control subjects…
Comparative studies of the Pschorr reaction in the pyrazole series. Access to the new dibenzo[e,g]pyrazolo[1,5-a][1,3]diazocine system of pharmaceuti…
2008
The diazonium tetrafluoroborate 11 obtained from 2-amino-N-methyl-N-(1-phenyl-3- methylpyrazol-5-yl)benzamide was transformed in dry acetonitrile via an ionic or radical pathway. Differences were observed with respect to ionic or radical transformations in aqueous media of the analogous diazonium hydrogen sulfate 1 derived from the same amine. In acetonitrile solution, the ionic pathway was characterized by an increased yield of 1,4-dimethyl- 3-phenyl-pyrazolo(3,4-c)isoquinolin-5-one 4 and by the formation of its isomer, the new derivative 7,9-dimethyldibenzo(e,g)pyrazolo(1,5-a)(1,3)diazocin-10(9H)-one 12. When the reaction followed a radical pathway, the pyrazolo(3,4-c)isoquinoline derivat…
The effect of some amines and alcohols on the organized structure of [bmim][BF4] investigated by 1H NMR spectroscopy
2008
The effect exerted by some amines and alcohols on the 1H NMR spectra of 1-butyl-3- methylimidazolium tetrafluoroborate [bmim][BF4] has been studied. This ionic liquid, which is one of the most widely used, is characterized by a high structural order degree, as a consequence of the symmetry and the coordination ability of the anion. In order to have information about the dependence of the detected effects on the alcohol or amine structure, some different primary, secondary and tertiary amines and alcohols have been considered. Furthermore, in the case of amines, their basicity has been also taken into account. Both amines and alcohols induce variation in chemical shifts values and signal mul…
Resorcinarene Podand with Amine-Functionalized Side Arms â Synthesis, Structure, and Binding Properties of a Neutral Anion Receptor
2009
The synthesis and structure of a neutral resorcinarene host bearing four amine-functionalized side arms is described. The anion binding properties were investigated in solution by 1H NMR spectroscopic titration and diffusion experiments and in the gas phase by mass spectrometric studies. It was observed that in solution 1:2 (host/guest) complexes were formed between the resorcinarene host and the basic fluoride and acetate anions, whereas in the gas phase 1:1 complexes with other anions (Cl–, HCOO–, NO3–, and BF4–) were detected additionally.

Towards a Comprehensive Understanding of Body Image: Integrating Positive Body Image, Embodiment and Self-Compassion.
2021
Body image (BI) disturbance is a relevant factor in the etiology and treatment of eating disorders (ED). Although progress has been made in recent decades in understanding BI and its relationship with ED, the efficacy of BI disturbance prevention and intervention programs is still limited. In order to reach deeper understanding of BI disturbance and clarify the interactions between some protective and risk factors related to this construct, we carried out a literature review on some specific BI-related factors that so far have been analyzed independently. We specifically examined positive and negative BI; embodiment and its role in the development of positive and negative BI; and self-compa…
Properties and constraints of cheating-immune secret sharing schemes
2006
AbstractA secret sharing scheme is a cryptographic protocol by means of which a dealer shares a secret among a set of participants in such a way that it can be subsequently reconstructed by certain qualified subsets. The setting we consider is the following: in a first phase, the dealer gives in a secure way a piece of information, called a share, to each participant. Then, participants belonging to a qualified subset send in a secure way their shares to a trusted party, referred to as a combiner, who computes the secret and sends it back to the participants.Cheating-immune secret sharing schemes are secret sharing schemes in the above setting where dishonest participants, during the recons…

Optimisation of Thermochromic Thin Films on Glass; Design of Intelligent Windows
2010
Theoretically thermochromic glazing has the potential to reduce energy consumption in buildings by allowing visible light for day lighting, reducing unwanted solar gain during the cooling season, while allowing useful solar gain in the heating season. In this study building simulation is used to predict the savings made by novel thermochromic glazing coatings compared to standard products, for locations with different climates. The results suggest that thermochromic glazing can have a significant energy saving effect compared to current approaches.
Characterization and reactivity of charcoal from high temperature pyrolysis (800-1600°C)
2019
This study presents the effect of wood origin and heat treatment temperature on the CO2 reactivity, nanostructure and carbon chemistry of chars prepared at 800, 1200, and 1600 °C in slow pyrolysis reactors. The structure of charcoal was characterized by transmission electron microscopy, Raman spectroscopy, mercury intrusion porosimetry and N2 adsorption. The CO2 reactivity of char was investigated by thermogravimetric analysis. Results showed that spruce and oak chars have similar reactivity at all heat treatment temperatures. The oak char prepared at 1600 °C contained long and flat graphene layers and interplanar distance that is similar to graphite and thus, was more ordered t…
