Gevrey local solvability in locally integrable structures
We consider a locally integrable real-analytic structure, and we investigate
the local solvability in the category of Gevrey functions and
ultradistributions of the complex d' naturally induced by the de Rham complex.
We prove that the so-called condition Y(q) on the signature of the Levi form,
for local solvability of d' u=f, is still necessary even if we take f in the
classes of Gevrey functions and look for solutions u in the corresponding
spaces of ultradistributions.Comment: 12 page
Malaria chemoprophylaxis recommendations for immigrants to Europe, visiting relatives and friends - a Delphi method study
BACKGROUND: Numbers of travellers visiting friends and relatives (VFRs) from Europe to malaria endemic countries are increasing and include long-term and second generation immigrants, who represent the major burden of malaria cases imported back into Europe. Most recommendations for malaria chemoprophylaxis lack a solid evidence base, and often fail to address the cultural, social and economic needs of VFRs. METHODS: European travel medicine experts, who are members of TropNetEurop, completed a sequential series of questionnaires according to the Delphi method. This technique aims at evaluating and developing a consensus through repeated iterations of questionnaires. The questionnaires in this study included questions about professional experience with VFRs, controversial issues in malaria prophylaxis, and 16 scenarios exploring indications for prescribing and choice of chemoprophylaxis. RESULTS: The experience of participants was rather diverse as was their selection of chemoprophylaxis regimen. A significant consensus was observed in only seven of 16 scenarios. The analysis revealed a wide variation in prescribing choices with preferences grouped by region of practice and increased prescribing seen in Northern Europe compared to Central Europe. CONCLUSIONS: Improving the evidence base on efficacy, adherence to chemoprophylaxis and risk of malaria and encouraging discussion among experts, using techniques such as the Delphi method, may reduce the variability in prescription in European travel clinics
ApiBooster: generatore di applicazioni web volte alla gestione di database generici
Il presente studio si basa su un progetto applicativo chiamato ApiBooster.
Questâapplicazione nascer`a con lo scopo di poter generare in modo automatico unâapplicazione web scritta in uno specifico standard che permetta
operazioni CRUD (Create, Read, Update, Delete) su un database, tramite
un documento scritto in un formato facilmente accessibile alla macchina e
sufficientemente di alto livello.
Lâapplicazione, non `e terminata. Necessita di una programmazione piuttosto
complessa, e il tempo a disposizione `e stato limitato. Sono state per`o create
e definite le basi applicative, su cui la tesi si incentra.
Lâapplicazione a cui si fa riferimento, quindi, `e costituita ancora da un progetto teorico, in quanto non esiste ancora una implementazione che possa
dirsi completa.
Questa applicazione `e stata progettata tenendo anche conto delle possibili future implementazioni che verranno spiegato nel paragrafo dedicato agli
sviluppi futuri
