A Novel Sinergy Between Remote Sensing and GIS for Oil Spill Detection on Satellite Imagery
No full textThe large amount of images available today, thanks to the increasing of the number of orbiting EO satellites (Earth Observation Systems), which are able to provide information of every region of the Earth, represents an indispensable instrument for monitoring any terrestrial ecosystem. EO systems allow to detect and follow fast changing phenomena (like natural and anthropic disasters) providing the needed information for planning the necessary measures and reduce the impact of these events. This paper aims at showing the results obtained through the transformation of Mathematical Morphology algorithms (which have already shown their effectiveness) in IDL based algorithms (using ENVI EX rule sets) that can provide identical performances. The direct execution of these algorithms in a GIS environment, taking into account topology restrictions, allows to directly generate maps containing potential oil spills isolated on satellite images (exploiting the geometrical and physical characteristics of oil spills) together with contextual information on the same maps (typical of the GIS environment, as the wind regime, presence of vessels, etc) in order to assign a probability to candidate spots and create a much more accurate oil spill detection process

Urban growth assessment around Winam Gulf of Kenya based on satellite imagery
No full textUrban growth and population dynamics are among the most critical information needed for future economic development planning, natural resources allocation and environmental management. In the present work, two methods, the first based on night-time images produced by NOAA and population maps provided by Oak Ridge National Laboratory's (ORNL) LandScan, and the second one on SAR imagery, were used in order to assess the expansion of urban areas surrounding the Winam Gulf (Lake Victoria, Kenya) at different scales. In the time covered by night-time lights imagery, the study highlighted a period of constant growth rate between 2002 and 2006 and a negative trend after 2006 and 2008. This decrease may be related to two main events occurring in the study area between 2006 and 2007: the decline of the Lake Victoria level and the abnormal proliferation of the floating weeds within the Winam Gulf. Meanwhile, the urban feature extraction obtained at a different scale within a particular district from 1997 up to 2008 results in a constant growth rate. Population movements around this zone explain different dynamics that should be studied in detail in order to understand their particular roots
New avenues of directing evolution in viral vector capsid bioengineering
No full textGene therapy offers the treatment of diseases caused by mutations in the patient’s genome.
The delivery of a healthy copy of the mutated gene to affected cells is central to this
intervention. Recombinant adeno-associated viral vectors (rAAV) are rapidly becoming the
vector of choice for gene delivery applications. One of the many distinguishing features of
rAAV vectors is the large diversity of capsid variants enabling a variety of cells and tissues to
be targeted for gene delivery.
While gene replacement and addition approaches remain the most common strategies
utilising rAAVs, refinements in the use of targeted nucleases have made rAAVs a promising
gene editing tool. Regardless of the intended application, the capsid variant utilised is a key
determinant of clinical efficacy. This thesis presents three endeavours undertaken
investigating capsid development and characterisation.
The first is an investigation of high-throughput tools for identifying high-performing capsid
variants and comparing non-human pre-clinical models. The second is a directed evolutionbased
selection platform enabling the reliable generation of novel capsid variants that enable
high levels of transgene expression. This technology was validated in two unrelated targets –
the human liver and the human retina – demonstrating its broad applicability. Finally, the
concept of directed evolution was applied to create a platform for generating novel capsids
with increased homology-directed repair outcomes in primary T-lymphocytes and
haematopoietic stem cells. This was the primary aim of the thesis and it was achieved by
incorporating the lessons learned from all previous studies.
In summary, over the course of this project, three key technologies were developed and
validated. All these technologies are highly impactful as they enable the choice of the optimal
capsids and model system as well as the most functional generation of novel capsids.
Moreover, novel capsids were generated in human hepatocytes, human retina, and cells of
the immune system

Are the PREFER project products devoted to support fire prevention and recovery suitable to South-America ?
No full textPREFER (Space-based information support for the Prevention and Recovery of Forest Fires Emergency in the Mediterranean Area) is a three years project devoted to develop a satellite based service infrastructure capable to provide up-to-date information to support the preparedness, prevention, recovery and reconstruction phases of the Forest Fires emergency cycle in the European Mediterranean Region. The project has been successfully completed at the end of 2015. This paper aims at illustrating some of the project achievements and discuss their applicability to manage forest fires in South-America

ADRIAN POP - IN SEARCH OF A LONG LOST SMILE
No full textAn anniversary, especially in the case of a generation colleague, the renowned composer Adrian Pop, generates the remembrance of a long series of musical events that have become notorious, with works included in the national and international concert repertoire. The avoidance of nostalgic memories made that a stage miniature be chosen for the present paper, an incursion of the author into the naive world of childhood reading. The result was a modern, glamorous musical transposition of a sequence with Max and Moritz, the playful heroes created by the famous humorist and cartoonist Wilhelm Busch in the middle of the 19th century. The musical act Onkel Fritz by Adrian Pop was first performed in Cluj in 2016, on October 22, on the occasion of his previous anniversary, within the Cluj Musical Autumn Festival. The graceful performers of the act, presented under the title “Anniversaries at the Festival, Adrian Pop compositional portrait”, were soprano Mihaela Maxim, in the role of Max and pianist Eva Butean, in the role of Moritz. How did composer Adrian Pop manage to musically enliven a 150 years old humorous story? The author of the following text will try to answer this question.
Rezumat. ADRIAN POP - ÎN CĂUTAREA SURÂSULUI PIERDUT. O aniversare, mai ales în cazul unui coleg de generație, reputatul compozitor Adrian Pop, generează rememorarea unui lung șir de evenimente muzicale devenite notorii, cu lucrări intrate în repertoriul intern și internațional de concerte. Evitarea unor memorii nostalgice au făcut ca sorții acestei comunicări să cadă asupra unei miniaturi scenice, o incursiune a autorului în lumea ingenuă a lecturilor din copilărie. A rezultat o transpunere muzicală modernă, plină de farmec, a unei secvențe cu Max și Moritz, eroii poznași creați de celebrul umorist și caricaturist Wilhelm Busch la mijlocul secolului XIX. Prima audiție clujeană a scenetei muzicale Onkel Fritz de Adrian Pop a avut loc în 2016, la 22 octombrie, cu ocazia precedentei sale aniversări, în cadrul Toamnei Muzicale Clujene. Interpreții plini de har ai scenetei prezentate sub genericul „Aniversări în Festival, portret componistic Adrian Pop” au fost soprana Mihaela Maxim, în rolul lui Max și pianista Eva Butean, în rolul lui Moritz. Oare cum a reușit compozitorul Adrian Pop să însuflețească muzical o poveste umoristică de 150 de ani? La această întrebare va încerca să răspundă autoarea acestor rânduri.
