Infinitesimal deformations of double covers of smooth algebraic varieties

2003

The goal of this paper is to give a method to compute the space of infinitesimal deformations of a double cover of a smooth algebraic variety. The space of all infinitesimal deformations has a representation as a direct sum of two subspaces. One is isomorphic to the space of simultaneous deformations of the branch locus and the base of the double covering. The second summand is the subspace of deformations of the double covering which induce trivial deformations of the branch divisor. The main result of the paper is a description of the effect of imposing singularities in the branch locus. As a special case we study deformations of Calabi--Yau threefolds which are non--singular models of do…

Jyväskyläläisten ravintoloiden anniskeluoikeudet ja valvonta 1932-1939

2015

Epäonnistuneen kieltolain myötä Suomeen laadittiin itsenäisyyden ajan ensimmäinen väkijuomalaki. Väkijuomalain myötä yksityiset henkilöt, yhdistykset, järjestöt sekä yksityiset kerhot saattoivat perustaa anniskeluravintoloita. Tässä tutkielmassa tarkastellaan Jyväskyläläisiä anniskeluravintoloiden anniskeluoikeusprosessia ja ravintoloiden valvontaa kieltolain päättymisestä vuonna 1932 talvisodan syttymiseen syystalvella vuonna 1939. Yhteiskunta oli sisällissodan myötä edelleen jakaantunut. Myös Alkoholiliike jakoi ravintolat yhteiskuntaluokkien mukaan. Tutkielman ensimmäisenä tavoitteena on selvittää, miten anniskeluoikeutta haettiin ja millaiset jyväskyläläiset ravintolat oikeutta hakivat …

Donne altrove. Viaggi, scrittura periodica e identità nell'Ottocento inglese

2015

The book focuses on the usage and publication of travelogues by 19th century women travellers to the colonies of the Empire as tools for spreading a new female identity based on courage, strenght, adventurous attitudes, in brief, based on all those features on which male identity had governed the economic, social, political and cultural areas, and last but not least, suffocated the so called 'fragile' gender. the travelogue, that is the writing of a a non fictional travel experience by women, to and in place such as the colonies, considered as the uncivilised and dangerous side of the Empire gave women the possibility to develop and perform their own selves as authoritative, mobile and powe…

The carbon footprint of a knowledge organization and emission scenarios for a post-COVID-19 world

2021

Publisher Copyright: © 2021 The looming climate crisis requires an immediate response, in which organizations, as major contributors, should play a central role. However, these organizations need appropriate tools to measure and mitigate their climate impacts. One commonly applied method is carbon footprint analysis. Carbon footprint analyses have been conducted for various types of organizations, but knowledge organizations, such as universities and research institutes, have received far less attention, because their carbon footprint is often less visible and can be easily underestimated. This study is based on the carbon footprint analysis of one multinational knowledge organization. This…

Widening use of dexamethasone implant for the treatment of macular edema

2017

Vincenza Bonfiglio, Michele Reibaldi, Matteo Fallico, Andrea Russo, Alessandra Pizzo, Stefano Fichera, Carlo Rapisarda, Iacopo Macchi, Teresio Avitabile, Antonio Longo Department of Ophthalmology, University of Catania, Catania, Italy Abstract: Sustained-release intravitreal 0.7 mg dexamethasone (DEX) implant is approved in Europe for the treatment of macular edema related to diabetic retinopathy, branch retinal vein occlusion, central retinal vein occlusion, and non-infectious uveitis. The implant is formulated in a biodegradable copolymer to release the active ingredient within the vitreous chamber for up to 6 months after an intravitreal injection, allowing a prolonged interval of effica…

New algorithms for atmospheric correction and retrieval of biophysical parameters in earth observation : application to ENVISAT/MERIS data

2007

An algorithm for the derivation of atmospheric and surface biophysical products from the MEdium Resolution Imaging Spectrometer Instrument (MERIS) on board ENVIronmental SATellite (ENVISAT/MERIS) Level 1b data over land has been developed. Georectified aerosol optical thickness (AOT), columnar water vapor (CWV), spectral surface reflectance and chlorophyll fluorescence (CF) maps are generated. Emphasis has been put on implementing a robust software able to provide those products on an operational manner, making no use of ancillary parameters apart from those attached to MERIS images. For this reason, it has been named Self-Contained Atmospheric Parameters Estimation from MERIS data (SCAPE-M…

Formulations and exact algorithms for the distance-constrained generalized directed rural postman problem

2017

[EN] The generalized directed rural postman problem is an arc routing problem with many interesting real-life applications, such as routing for meter reading. In this application, a vehicle with a receiver travels through a series of neighborhoods. If the vehicle gets closer than a certain distance to a meter, the receiver is able to record the gas, water, or electricity consumption. Therefore, the vehicle does not need to traverse every street, but only a few, to get close enough to each meter. We study an extension of this problem in which a fleet of vehicles is available. Given the characteristics of the mentioned application, the vehicles have no capacities but there is a maximum distan…

Fluvial activity of the late-glacial to Holocene “Bergstraßenneckar” in the Upper Rhine Graben near Heidelberg, Germany – first results

2022

Abstract. The term “Bergstraßenneckar” (BSN) refers to an abandoned course of the river Neckar. It flowed in a northern direction east of the river Rhine in the eastern part of the northern Upper Rhine Graben in southwestern Germany. The former meandering course merged with the Rhine ca. 50 km further north of the site of the present-day confluence near Mannheim. The palaeo-channels are still traceable by their depressional topography, in satellite images and by the curved boundaries of adjacent settlements and land parcels. In the plan view, satellite and aerial images reveal a succession of meander bends, with older bends being cut off from younger channels. Based on stratigraphic investi…
