Bucharest 2025: A new paradigm

Bucharest is an urban palimpsest, its spatial characteristics bearing the trace of all ideological changes within its urban fabric. Its accelerated development in two stages (1850s- 1930s and 1950s-1989) generated a superposition of fragmented urban projects (signs of various stages of modernity) that were never finished. These stages in its evolution were generated by advances in technology and therefore the reformulation of the infrastructural framework, and changes in the perception of open-spaces as main arenas of publicness. After 1989, the inability of the City to produce a new infrastructural paradigm and its careless treatment of the open-space through market speculation produced chaotic development, extreme fragmentation, lack of public space, and last but most important, the lack of public trust in planners. With this problem setting in mind there are a few questions that become the backbone of this thesis: How could we use infrastructure and open-space to describe the future of Bucharest? Can they act as frameworks to produce a new paradigm for the city? Can Bucharest become a testing ground for conjectures that become relevant at a wider scale? These are the main questions to which this thesis research should be able to answer. By developing conjectures illustrating how Bucharest could be shaped around infrastructure and open-space, the ambition of this work is to produce guidelines and tools for an isotropic and permeable Bucharest.EMUUrbanismArchitectur

Soil diseases and nematodes cause great damages to vegetable crops and represent some of the most limiting factors for farmers' income. Their global management was based on the soil’s fumigation with methyl bromide before planting, a compound whose elimination procedure was initiated by the Protocol from Montreal (1992), due to its dangerous effects on the environment. Romanian Government decided to eliminate gradually the use of methyl bromide since 2005. In the recent years, the research has focused on investigationthe alternatives to methyl bromide for prevention and combating the soil diseases and nematodes, particularly in protected vegetable crops. These alternatives were based both on the use of other chemical compounds and some non-chemical methods (soil disinfection with steam, use of green houses, culture practices, improving the resistance of plants). The purpose of this paper is to present the actual achievements to in grafting of vegetables in Romania

DNA barcoding and faunistic criteria for a revised taxonomy of Italian Ephemeroptera

<p>Mayfly (Ephemeroptera) systematics has considerably changed over the years, but many questions have yet to be answered. The synergistic connection between traditional knowledge and new data sources, producing increasingly complex information, has become a compelling issue for modern taxonomy. Molecular tests and the use of reliable reference sequence libraries may constitute effective complements to the traditional method in guiding recognition of species and giving information about taxonomic incongruences which require further examination. In the present study, we sought to verify the current Italian mayfly nomenclatural system through DNA barcoding and relevant points to reliably manage the available amount of morpho-ecological and molecular data are discussed. We investigated COI (Cytochrome oxidase I) sequence variation in 163 individuals of Italian mayflies, 126 of which were previously assigned to 24 morphologically recognised species, and 37 could be attributed only to generic taxonomic entities (“sp.”, “cf.” or “gr.”). DNA barcoding statistical tests for species delimitation hypotheses based on genetic distances and inferred gene trees were integrated with GenBank searches and surveys of the historical literature to better understand the knowledge acquired on the status and diversity of the investigated taxa. Combined criteria to define three categories of reliability were then assessed. Concurrent data allowing unambiguous identification were attained for only eight species. High intraspecific genetic distances (> 3%) and a lack of reliable reference material or convincing taxonomic information evidenced 29 critical states, deserving further investigation. Solid species names, potential cryptic species and entities about which little is known are pointed out for a future upgrade/reorganisation of the taxonomy of Italian Ephemeroptera.</p
