Computational determination of the dominant triplet population mechanism in photoexcited benzophenone
2014
In benzophenone, intersystem crossing occurs efficiently between the S-1(n pi(star)) state and the T-1 state of dominant n pi(star) character, leading to excited triplet states after photoexcitation. The transition mechanism between S-1(n pi(star)) and T-1 is still a matter of debate, despite several experimental studies. Quantum mechanical calculations have been performed in order to assess the relative efficiencies of previously proposed mechanisms, in particular, the direct S-1 -> T-1 and indirect S-1 -> T-2(pi pi(star)) -> T-1 ones. Multiconfigurational wave function based methods are used to discuss the nature of the relevant states and also to determine minimum energy paths a…

Pedestrian Safety Indicators Study
2008
Pedestrian mobility can be considered an important feature in a new model of town organization, being suitable for the newly urbanized areas as well as the old quarters and the outskirts, places where streets and squares, once devised for a pedestrian based mobility, were eventually overcame by an ever increasing motorized traffic. Enhancing pedestrian mobility could bring new life and activities into the old and historic parts of the town reviving their original identities. The last decade’s increase in the recourse to private cars requires improvements in pedestrian mobility quality. This can be achieved by building new infrastructures, limiting the use of private cars, improving public t…
Metabolites of diethylstilboestrol induce sister chromatid exchange in human cultured fibroblasts
1979
Diethylstilboesterol (DES) is one of the few substances for which a clear association with carcinogenicity has been established in man. Nevertheless, it is still widely used, mainly as a cheap oestrogen to increase the slaughter weight of beef, but in spite of this it is not known if residues in the meat or metabolites excreted by the cattle are hazardous to man. It is also unknown whether there is a threshold dose below which DES is harmless. A threshold might be expected if a hormonal mechanism of carcinogensis rather than metabolic activation to an electrophically reactive species operats. This possibility was supported by the observations that DES, in contrast to most other carcinogens,…
Dispersion relation bounds forππscattering
2008
Axiomatic principles such as analyticity, unitarity, and crossing symmetry constrain the second derivative of the $\ensuremath{\pi}\ensuremath{\pi}$ scattering amplitudes in some channels to be positive in a region of the Mandelstam plane. Since this region lies in the domain of validity of chiral perturbation theory, we can use these positivity conditions to bound linear combinations of ${\overline{l}}_{1}$ and ${\overline{l}}_{2}$. We compare our predictions with those derived previously in the literature using similar methods. We compute the one-loop $\ensuremath{\pi}\ensuremath{\pi}$ scattering amplitude in the linear sigma model (LSM) using the $\overline{\mathrm{MS}}$ scheme, a result…
External managerial networking in meta-organizations. Evidence from regional councils in Norway
2019
Municipalities increasingly engage in cooperation with other municipalities to realize economies of scale and scope, to solve ‘wicked problems’ and to manage border crossing challenges. Often, such...
Teachers’ perceptions of autonomy in the tensions between a subject focus and a cross-curricular school profile: A case study of a Finnish upper seco…
2020
AbstractRecent research has indicated global trends of decreasing teacher autonomy and increasing teacher accountability. Standardised national tests have been identified as one of many factors constraining teacher autonomy. Another trend influencing teachers’ scope of action is the profiling and branding of schools that compete for students. This qualitative case study concerns the general upper secondary level in Finland, the only level of education in the country with a high-stakes final examination—the matriculation exam. The upper secondary level is generally regarded as Finland’s most subject-focused level of education. In contrast to this subject-focused tradition, the case school fo…
Effetto di tre diversi edible coating a base di gel di Aloe vera sulla qualità di frutti di kiwi di IV gamma
2021
Negli ultimi anni, il mercato della frutta di IV gamma si è contraddistinto per una crescita esponenziale legata ai ritmi di vita più intensi rispetto al passato, che spingono a privilegiare prodotti offerti in porzioni, utilizzabili in modo facile e veloce. La frutta di IV gamma è caratterizzata, però, da una breve durata di conservazione a causa delle fasi di lavorazione e preparazione che accelerano i processi di maturazione. Lo scopo di questo lavoro è stato quello di analizzare sulla qualità di kiwi della varietà “Hayward” in IV gamma l’effetto di tre diversi rivestimenti commestibili basati su (1) Aloe vera gel (AVG), (2) Aloe vera gel + idrossipropilmetilcellulosa (HPMC), (3) Aloe ve…
