A methodology for mapping co-benefits of climate adaptation. Participatory GIS in consultancy
This thesis seeks to broaden the research of Geographic Information Systems (GIS) in the context of citizen engagement and co-benefit mapping, by bringing forth consultancy perspectives and demands towards the uptake of new methods. The process is anchored in the Action Research methodology, as the empirical material is produced through a collaboration with the Ramboll consultancy. The thesis follows the process of creating a methodology for the spatial delineation of co-benefits within climate adaptation. It investigates how an otherwise analogue methodology can be enhanced by using digital tools based on GIS. The pinnacle of this process is the testing of the method, which could form the basis for co-benefit assessments, in two cases situated in a Western European context. The thesis discusses both the consultancy considerations for the adoption of a new participatory method, as well as the implications of using citizen knowledge in this process. One of the main research findings is the missing link between the concepts of place values, ecosystem services and co-benefits of climate adaptation, which is closely tied to the timing of the assessment, prior to or after climate adaptation measures. Local circumstances and project requirements dictate the introduction of a new digital method that is based on participatory GIS (PGIS), and partly the teamâs resources. Integrating citizen knowledge in co-benefit assessments carried out in GIS is strongly related to the main difficulties of co-benefit assessments, such as overlapping and conflicting values. In addition to that, outreach is essential for a successful outcome, but also resource demanding
Subdifferential calculus and ideal solutions for set optimization problems
We explore the possibility to derive basic calculus rules for some
subdifferential constructions associated to set-valued maps between normed
vector spaces. Then, we use these results in order to write optimality
conditions for a special kind of solutions for set optimization problems
Conic cancellation laws and some applications
We discuss, on finite and infinite dimensional normed vector spaces, some
versions of Radstr\"{o}m cancellation law (or lemma) that are suited for
applications to set optimization problems. In this sense, we call our results
"conic" variants of the celebrated result of Radstr\"{o}m, since they involve
the presence of an ordering cone on the underlying space. Several adaptations
to this context of some topological properties of sets are studied and some
applications to subdifferential calculus associated to set-valued maps and to
necessary optimality conditions for constrained set optimization problems are
given. Finally, a stability problem is considered
Antifungal activity of essential oils and homemade fungicides against Passalora Fulva
Passalora fulva is a pathogen which causes the disease on tomato known as the tomato leaf mold. In the
greenhouses, this disease causes big problems during the fall, in early winter and spring, due to the high
relative humidity of air and the temperature. The development of the disease is quick, moving from lower to
upper leaves so the controlling must be done as soon as possible. The antifungal activity of medicinal plants
bioactive compounds has gained a lot of attention within the scientific community. The main factor is the
growing problem of multidrug resistance among pathogenic fungi. In addition, medicinal plant oils are the
promising sources of antifungal drugs. Based on these facts, the present study emphasizes the importance of
plants EOs as an alternative against pathogenic fungi causing tomato leaf mould. The spread of pesticide
resistant pathogens is one of the most severe threats to successful treatment of microbial diseases. Renewed
recent interest towards EOs utilization has been attributed to several factors, including a general revival in
the appeal of ânaturalâ products, the desire for antimicrobial compounds with considerably better safety and
toxicity profiles, and more importantly, the need for alternative ways to conventional antimicrobial, since
they show reduced susceptibility to many major pathogens. In this paper we have analyzed possible
substitutes to synthetic pesticides in controlling the fungus. Since the potential of essential oils (EOs) as
antimicrobial agents is well established and farmers around the world already use traditional recipes, we
have decided to test a fair amount of essential oils and homemade fungicides against the growth of Passalora
fulva mycelium. We have discovered cloves EO kills the fungus at any tested concentration. The next EOs
with strong effects are cinnamon, lemongrass, palmarosa, oregano and oil grass. The rest of EOs have shown
a medium inhibitory effect
MM-Wave Metamaterial Adjustable Antenna on Magnetically Biased Ferritic Substrate
The paper presents a mm-wave metamaterial coplanar waveguide (CPW) zeroth-order resonating (ZOR) antenna on magnetically biased ferrite substrate. The measurements demonstrate tuning of the resonant frequency and steering of the radiation characteristic depending on the strength of biasing magnetic field. The resonant frequency shifts about 1.1âGHz for magnetic biasing field strength variation between 0âT and 0.265âT. The return loss is reduced as result of elimination of ferrite low field loss. The radiation characteristic in transversal plane steers between approximately â15° and +14° depending on the magnetic field strength. In the magnetically unbiased state the antenna gain is 4.16âdBi and increases slightly to 4.22âdBi due to small field loss reduction following the magnetic polarization application
The influence of agrometeorological characteristics of the agricultural year 2019-2020 on wheat crop in the North-East part of Moldova
The study based on the aforementioned theme puts to distinguish specifics agrometeorological characteristics of the
agricultural year 2019-2020 in the North-East part of Moldova, and its influence on growth and yield in winter wheat
crop. Itâs presented the average values of precipitations and air temperature for the last decade and the values of
precipitations and air temperature recorded between September 2019 and July 2020 and its influence in winter wheat
crop. The climatic conditions encountered during the agricultural year 2019-2020 and, especially in the first half of
2020 made this year a very special one, being characterized by the presence of a severe drought, with strong negative
influences on growth of cultivated plants and especially of winter wheat
Contribution to the knowledge of the micromycetes from the spontaneous flora identified in Iasi county region, Romania
Permanent knowledge of distribution, diversity and interactions between organisms, plants and the environment in
which they live is extremely important for the conservation of biodiversity. Interest for biodiversity conservation is
intensified by concern bout the conservation of genetic resources, destruction of forest, extinction of species and the
effects of global warming. This paper presents some parasitic micromycetes identified on plant species from different
areas of Iasi County. In our fieldwork made in the spring of 2021 year were indentified some parasitic micromycetes to
spontaneous flora species as: fumewort (Corydalis solida L. Clairv.), alpine squill (Scilla bifolia L.), buttercup anemone
(Anemone ranunculoides), lesser celandine (Ranunculus ficaria L.) Či snake's head fritillary (Fritillaria meleagrioides
Patrin ex Schult. & Schult. f.) Identified micromycetes cause some plant diseases as downy mildew or rust and this
fungi species belong to some different taxonomy: Those who cause downy mildew are from Oomycetes class, and rust
are from Teliomycetes class as Tranzschelia, Puccinia.Či Uromyces genera
