    Foreword Lucia Ruggeri The effective enforcement of energy transition is one of the keys to the successful fight to climate change. The interplay between the sustainable UN Agenda 2030 goals is a new interesting ground for the development of intersectorial and multidisciplinary studies. Thanks to University of Camerino which is focused on the contamination between different scientific areas and really engaged in strengthening international research, a group composed by more than forty researchers of ten different nationalities is studying the energy policies and the new phenomenon of energy prosumerism. This book is the first direct result of the research activities granted by University of Camerino under the Programme FAR 2019 in the ECPE Project ‘Enabling Consumer to become Prosumer in the Energy transition era’ (more details about the project ECPE are available at https://ecpe.unicam.it/). The object of this book is to collect and analyze the main barriers to self-consumption and prosumerism. Difficult as it is to discuss all obstacles in a single volume, the book focuses on selected barriers which impede the development of new types of fossil free energy production and consuption. The energy communities could play a central role in the implementation of the energy transition strategies, but legal, social, economic, political and cultural barriers can hinder their spread. To analyze the barriers and to find how to eliminate the obstacles to energy transition policies is pivotal to enhance research activities focused on the new EU Regulatory framework. Most in general it is crucial a multidisciplinary approach focused on the fight to climate change and the implementation of sustainable development. In this book are collected several articles which offer a different perspective on the energy transition barriers form different points of view and under different methodologies. The book is composed of four parties. The first one is dedicated to the analysis of the methodology and the results offered by questionnaires supplied online in two languages (Italian/English). The survey is the basis of the Working Paper which is the deliverable of the ECPE Work Programme n. 2 and which constitutes the ground for a discussion into the research group. The second part of the volume collects the contributions focused on the social and economic barriers to prosumerism, while the third one is dedicated to a description of failure cases of self consumption

    The detection of the blazar 3C279 at a record distance z=0.54 by MAGIC, and of other distant blazars by H.E.S.S. and VERITAS, indicate that the Universe is more transparent to very-high-energy gamma rays than previously thought on the basis of the estimates of the density of Extragalactic Background Light. The physical implications of these measurements will be discussed

    Sensitive and reliable gas chromatography tandem mass spectrometry assay for ethyl glucuronide in neonatal meconium

    Prenatal exposure to maternal ethanol leads to serious physical and mental irreversible disabilities. Ethyl glucuronide (EtG) is a direct metabolite of alcohol and its measurement in neonatal meconium has been established as the best biomarker to assess prenatal exposure to social and excessive gestational ethanol. We developed and validated the first gas chromatography tandem mass spectrometry method to quantify EtG extracted from meconium by a simple solid phase extraction pretreatment. The method was linear from limit of quantification (2 ng/g) to 200 ng/g matrix with good determination coefficient (r2 = 0.99). Recovery of EtG from meconium was always higher than 70% and intra-assay and inter-assay precision and accuracy were always better than 10%. Robustness of the developed GC–MS/MS method was tested by analysing 150 real samples coming from a previous national epidemiological project pre-screened through an ultra-chromatography tandem mass spectrometry assay obtaining a good comparability of results obtained by the two methods

    OBJECTIVE: New fentanyl analogues have been constantly emerging into the illegal drug market as cheap substitutes of heroin posing a serious health threat for consumers because of their high toxicity. Analytical methods to disclose the presence of these compounds in biological fluids of intoxicated individuals need to be updated to keep up with the new trends. In this study, we updated an ultra-high-performance liquid chromatography- tandem mass spectrometry method previously developed, for detecting some new fentanyl analogues and metabolites (sufentanil and norsufentanil, cis-3-methylnorfentanyl, trans-3-methylnorfentanyl, metabolites of cis and transmethylfentanyl, beta-phenylfentanyl, phenylfentanyl, para-fluoro furanyl fentanyl, isobutyryl fentanyl and ocfentanil) in urine sample. MATERIALS AND METHODS: Urine samples were simply diluted before injection in the chromatograph equipped with a reversed phase microcolumn. Detection was achieved with a triple quadrupole mass spectrometer with an electrospray ionization source in positive ion mode and operated in multiple reaction monitoring. RESULTS: The chromatographic separation was short (5 min) and the method was fully validated with a high sensitivity being limits of quantifications from 0.003 to 0.066 μg/L urine for the analytes under investigation. CONCLUSIONS: The suitability of the method was tested with urine specimens from former heroin addicts, which resulted positive by immunological screening to the class of fentanyl analogues. This method represents a valid tool to document recent exposure to the above-reported compounds for clinical and forensic purposes

    10 pages, 3 figures, proceedings Vulcano workshop (22nd - 27th May, 2006), Frontier Objects in Astrophysics and Particle Physics, F. Giovannelli & G. Mannocchi (eds.), Italian Physical Society, Editrice Compositori, Bologna, ItalyThree binaries are now established sources of emission at very high energies (>1e11 eV). They are composed of a massive star and a compact object. The emission can be due to the interaction of the relativistic wind from a young ms pulsar with the stellar wind of the companion, by which rotation-power ends up as non-thermal flux. Variations at VHE energies are explained as due to gamma-gamma absorption and/or changes in shock location along the orbit. Resolved radio emission is due to cooling particles trailing the pulsar

    We developed and validated a new rapid and sensitive gas chromatography-tandem mass spectrometry method for the determination of cocaine and its metabolites benzoylecgonine, norcocaine, ecgonine methyl esther and cocaethylene in hair of consumers. Hair samples were firstly decontaminated with three subsequent dichloromethane washes, then incubated for one hour with M3® buffer to promote analytes solubilization and stabilization and finally solid phase extracted. All extracts were derivatized and injected into GC–MS/MS with electron impact ionization. Multiple Reaction Monitoring was used for the acquisition of characteristic analytes ion transitions reaching a high sensitivity 0.01 ng/mg COC and metabolites limit of quantification. The method was linear in the COC and metabolites calibration ranges (LLOQ-10 ng/mg and LLOQ-1 ng/mg, respectively). Intra-assay and inter-assay precision were always lower than 15 %, accuracy never exceeded ± 6.6 %. The main advantages of the presented method are the fast, simple and innovative pretreatment procedure together with the instrumental sensitivity that allowed to measure also less concentrated metabolites
