Evaluation and Feasibility Study of Retrofitting Interventions on Social Housing in Italy

Abstract While there are an increasing number of new projects aiming at combining high residential quality and low power consumption, it is clear that the main challenge in the short term concerns the performance upgrading of the existing residential buildings stock. The feasibility analysis should consider the economic implications of the retrofit projects. A Disocunted Cash Flow analysis can be implemented in order to investigate the economic aspects of such interventions. The DCF approach allows the analysis of costs as well as the revenues and savings with the objective of understanding the period of time needed to recover the initial investment

Chemical and Biological Characterization from Condalia microphylla Fruits, a Native Species of Patagonia Argentina

Condalia microphylla Cav. (Rhamnaceae), popularly known as “piquillin”, is widely distributed in Patagonia. The drupes are consumed as fresh fruits by Argentine communities. The aim of this work was to quantify the nutritional value of C. microphylla fruit and the phenolic compounds present and to determine the functional antioxidant properties in vitro and in vivo. The nutritional value was determined according to the Association of Official Analytical Chemists (AOAC) methodology, and phenolic compounds were quantified by diode-array detection (HPLC-DAD). Antioxidant activity in vitro and in vivo was analyzed through the use of the radical species 2,2-diphenyl-1-picrylhydrazyl (DPPH) and zebrafish model, respectively. Quercetin-3-O-rutinoside (rutin) was the single principal phenolic compound. The extracts contained in vitro antioxidant activities and total phenolic contents (TPCs) between 1,143 ± 112 µg and 4,633 ± 174 µg gallic-acid equivalents (GAEs) per 100 g dry weight (DW), though no relationship was found between the latter parameter and the antioxidant activity of the extracts. When zebrafish larvae were exposed to oxidative stress (2.4% v/v H2O2), a concentration as low as 1.44 µg of GAEs/mL of piquillin-derived polyphenols inhibited lipid oxidation by up to 40%. Thus, in view of these advantageous functional food properties and the opportunity to exploit this Patagonian natural resource, piquillin consumption should be promoted worldwide.Fil: Boeri, Patricia.

Energy Community in Action—Energy Citizenship Contract as Tool for Climate Neutrality

Cities are responsible for 65% of energy consumption and for the 70% of CO2 emissions. Incisive actions are fundamental to bring cities towards climate neutrality by 2050 working by and for the citizens. For this reason, the “100 climate-neutral cities Mission” anticipates the target of climate neutrality by 2030. The objective of this paper, developed within the H2020 GRETA project—GReen Energy Transition Actions (GA101022317), is to investigate energy communities and climate city contracts as key interventions to face the ambitious goal of implementing citizenscentered and climate-neutral cities. To achieve this objective, this paper is structured as follows: (1) an updated framework of European and Italian legislation concerning energy communities; (2) an overview of climate city contracts’ definition and key aspects; (3) a selection and analysis of energy communities’ case studies; (4) a description of already developed pilot climate city contracts. The results provide more advanced knowledge about EU energy communities strategies and about the possible contractual agreements that can guarantee commitment between parties and can allow the active participation of citizens in the energy system. The lessons learned contribute to the application in the GRETA Italian case study, whose first participation activities are also described in the paper

Non-compete agreements in a rigid labour market: the case of Italy

Non-compete clauses (NCCs) limiting the mobility of workers have been found to be rather widespread in the US, a flexible labour market with large turnover rates and a limited coverage of collective bargaining. This paper explores the presence of such arrangements in a rigid labour market, with strict employment protection regulations by OECD standards and where all employees are, at least on paper, subject to collective bargaining. Based on a representative survey of employees in the private sector, an exam of collective agreements and case law, we find that in Italy i) collective agreements play no role in regulating the use of NCCs while the law specifies only the formal requirements, ii) about 16% of private sector employees are currently bound by a NCC, iii) NCCs are relatively frequent among low educated employees in manual and elementary low paid occupations having no access to any type of confidential information, and iv) in addition to NCCs, a number of other arrangements limit the post-employment activity of workers. Many of the NCCs do not comply with the minimum requirements established by law and yet workers do not consider them as unenforceable and appear to behave as they were effective. Even when NCCs are unenforceable they appear to negatively affect wages when they are introduced without changing the tasks of the workers involved. Normative implications are discussed in the last section of the paper

COMMUNITY ENGAGEMENT AND GREENING STRATEGIES AS ENABLING PRACTICES FOR INCLUSIVE AND RESILIENT CITIES

The climate change challenges call for innovative and sustainable policies and governance models, capable of achieving adaptation and mitigation goals working on a necessary behavioural societal change, both at individual and collective levels. Cities and their public spaces represent an ideal ground for the implementation of innovative strategies, which combine participatory and engagement practices to physical transformations of urban areas in a regenerative perspective. Co-design and participatory paths can trigger reactivation and re-appropriation of underused spaces, generate new dynamics in the public space use and provide effective solutions to tackle climate change, improving outdoor microclimatic comfort conditions. The implementation of demonstrative and temporary interventions – based on greening actions co-created with local administrations, stakeholders and citizens and supported by technologies – represents a viable and effective practice in order to experiment, test, monitor and evaluate shared pathways to more liveable, resilient and sustainable cities. This combined approach was experimented in the Bologna University area by the EU Horizon 2020 project ROCK – Regeneration and Optimisation of Cultural Heritage in Creative and Knowledge Cities (GA 730280) – through a series of pilot actions aimed at public open space utilization and potential enhancement in particular in the historical city centres, generating new resilient processes in terms of environmental sustainability and social inclusion

Efficacy and safety of dapoxetine in treatment of premature ejaculation: an evidence‐based review

SummaryBackground Premature ejaculation (PE) is a major issue in male sexual health, with a global prevalence estimated to be between 20% and 40%, making it the most common sexual dysfunction in men. PE causes distress and reduced quality of life for patients and has a negative impact on interpersonal relationships. Historically, it has been treated with cognitive therapy, behavioural methods and off-label use of selective serotonin reuptake inhibitors (SSRIs) usually used to treat depression and other psychological disorders. Dapoxetine is the only SSRI specifically designed to treat PE. Mechanism of action Dapoxetine hydrochloride is a potent inhibitor of serotonin reuptake transporters. Dapoxetine is suited for 'on-demand' treatment of PE because of its rapid absorption and short initial half-life. Efficacy Evidence from published studies showed that dapoxetine 30 mg or 60 mg taken 'on-demand' results in a significant increase in intravaginal ejaculatory latency time (IELT) when compared with placebo. Most patient-reported outcomes are clearly improved relative to placebo following dapoxetine therapy, indicating greater control over ejaculation, more satisfaction with intercourse, less ejaculation-related distress and significantly reduced interpersonal difficulties. Safety The most common adverse events with dapoxetine are nausea, dizziness, somnolence, headache, diarrhoea and insomnia. Usually they do not lead to drug discontinuation. Conclusion Dapoxetine is the only effective and safe available on-label oral treatment for PE, and its use can result in better quality of life for the patient and their sexual partner

Outdoor Comfort: The ENVI-BUG tool to Evaluate PMV Values Output Comfort Point by Point

Abstract Studies on Outdoor Comfort in urban open spaces adopt several tools and software to simulate microclimate models, energy performances and the fluid-dynamics of winds. Air temperature, wind speed, relative humidity are the typical input data used by the software to evaluate comfort indexes such as the Predicted Mean Vote [PMV], the Physiological Effective Temperature [PET] or the Universal Thermal Climate Index [UTCI]. Among the available software, Envi-met provides accurate outputs as well as the PMV index space distribution starting from a three-dimensional microclimate model. However it is affected by some limitations for what concerns a user centered approach including the changes in human metabolic activity (met) or clothes (clo). This paper offers a synthesis of a study performed on ENVI-BUG, an Envi-met algorithmic app, to obtain a fast calculation and distribution of local PMV point-by-point displayed with mannequin representation

Library Indoor microclimate monitoring with and without heating system. A Bologna University Library case study

This paper aims to illustrate and give an interpretation of the results emerged from a pilot activity developed within the ROCK project, by the Department of Architecture of the University of Bologna, Alma Mater Studiorum. Through this activity, we studied the indoor microclimate of the University Library of Bologna (BUB), in the Archive and in the Lecture Hall, with the aim to detect how these spaces are affected by the influence of factors such as the outdoor climate and the cooling and heating systems. Moreover, the paper presents the customisation of the probes’ alert system and of the probes itself, used for a one-year monitoring campaign started on the 20th of December 2018. In addition, we calculated the Heritage Microclimate Risk index, to verify the level of risk to which the heritage in the Library is exposed due to the indoor microclimate, and the Predicted Risk of Damage index, that evaluate the more specific risks of damage to which precise objects hosted in there are exposed. Therefore, this paper enriches the research field of Historic Indoor Microclimate, started in 2013, which concerns issues as preventive conservation and restoration in historic buildings. The new insights about the Bologna University Library facilitate the possibility to draw up a specific ‘Indoor Microclimate Management Protocol (IMMP)’ aimed at the preventive conservation of manuscripts and books in historical libraries
