Relationship Between Cannabis Use and Erectile Dysfunction: A Systematic Review and Meta-Analysis
2019
Globally, there is increasing usage and legalization of cannabis. In addition to its reported therapeutic effects, cannabis has several health risks which are not clearly defined. Erectile dysfunction (ED) is the most common male sexual disorder and there are plausible mechanisms linking cannabis use to ED. No attempt has been made to collate the literature on this topic. The aim of this review was to summarize the prevalence and risk of ED in cannabis users compared to controls. A systematic review of major databases from inception to January 1, 2019, without language restriction, was undertaken to identify studies investigating cannabis use and presence of ED. The analysis compared the p…
The Recurrent Characteristics of Historic Buildings as a Support to Improve their Energy Performances: The Case Study of Palermo
2017
Abstract The analysis of the recurrent characteristics of the local historic architecture is useful to develop large-scale energy analyses, regulations and financial strategies, but also to support technical guidelines for an energy improvement balanced with conservation. For this purpose, a multi-scale methodology ranging from envelope components to the urban dimension is necessary. In the research here exposed, this approach is investigated by focusing on the historic architecture of Palermo. For this heritage, the collection of thermal and hygrometric data for envelope components is combined with the examination of representative constructions, based on building stock categorization. Int…
An Autonomous System to Take Angular Thermal-Infrared Measurements for Validating Satellite Products
2015
An autonomous system for field land surface temperature (LST) measurements taken at different observation angles was developed to be deployed easily at any conventional meteorological tower station. The system permits ground-truth data to be acquired on a continuous basis, and angularly scans land and sky hemispheres with a single thermal-infrared (TIR) radiometer. This paper describes the autonomous angular system and the methodology to assess ground-truth LST and relative-to-nadir emissivity data from system measurements. Ground-truth LSTs were used to validate satellite-retrieved LST products at two experimental sites (rice crop and shrubland areas). The relative-to-nadir emissivity valu…
High Frequency Data Acquisition System for Modelling the Impact of Visitors on the Thermo-Hygrometric Conditions of Archaeological Sites: A Casa di D…
2018
[EN] The characterization of the microclimatic conditions is fundamental for the preventive conservation of archaeological sites. In this context, the identification of the factors that influence the thermo-hygrometric equilibrium is key to determine the causes of cultural heritage deterioration. In this work, a characterization of the thermo-hygrometric conditions of Casa di Diana (Ostia Antica, Italy) is carried out analyzing the data of temperature and relative humidity recorded by a system of sensors with high monitoring frequency. Sensors are installed in parallel, calibrated and synchronized with a microcontroller. A data set of 793,620 data, arranged in a matrix with 66,135 rows and …
Environmental Effects on Mechanical, Thermophysical and Electrical Properties of Epoxy Resin Filled with Carbon Nanofillers
2019
The aim of this work was to establish the effect of environmental factors (moisture and temperature) on some mechanical, electrical and thermal properties of epoxy-based composites filled with carbon nanofillers: nanotubes (CNT), nanofibers (CNF) and hybrid nanofiller (nanotubes/nanofibers in the ratio 1:1) and to reveal the most environmentally stable NC. First, the nanocomposites (NC) containing different nanofiller contents were prepared to evaluate electrical percolation threshold and to choose NC at certain electrical conductivity for further characterization of the physical properties in initial state and during/after environmental ageing. The environmental ageing consisted of water a…
Verifying the predicted risk of extinction based on ecological characteristics
2021
Red List status of species should reflect species extinction risk. Because data are limited and species response has a time lag, species may be threatened by extinction even if they are not Red‐Listed. The ability to predict species risk of extinction from ecological characteristics holds promises for proactively targeting conservation measures to species at high risk. In 2005, the risk of extinction from ecological characteristics was predicted for 81 species of Finnish butterflies. Now, after 15 years and two additional national Red List assessments, these predictions are verified. Species with a higher risk of extinction according to the original ecological extinction risk rank (EERR) ha…
Samtal om Budkavlen : hågkomster från 1970–1990-talen
2022
Med anledning av Budkavlens 100-årsjubileum fick jag i uppdrag att intervjua två av tidskriftens tidigare medarbetare – professor emeritus Nils Storå och intendent John Hackman – om deras erfarenheter av utgivningen av tidskriften under 1970–1990-talen. Nils Storå (f. 1933) var professor i nordisk etnologi under åren 1972–1997 och John Hackman (f. 1942) var amanuens vid Sjöhistoriska museet 1972–1975 och därefter intendent vid Etnologiska institutionen fram till sin pensionering 2005. Texten nedan ger en bild av hur det var att driva en humanistisk vetenskaplig tidskrift under 1900-talets sista decennier. Samtalet som återges är fiktivt i den meningen att jag valt att placera mina frågor oc…
Information, Communications and Media Technologies for Sustainability: Constructing Data-Driven Policy Narratives
2021
This paper introduces the idea of data-driven narratives to examine how the use of information, communications, and media technologies (ICMTs) impacts the sustainable growth of economies. While ICMTs have regularly been advocated as a policy tool for growth and development, there is a research gap in empirical studies validating how such policies may be effective. This analysis is based on historical panel data from 39 economies across the developed North (19) and developing South (20). The industry-standard Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology was applied to construct narratives that weave extant theories with empirical data. The art of developing data-dri…
Un bassin extensif formé pendant la fonte de la calotte glaciaire hirnantienne : le bassin ordovico-silurien de Kandi (Nord Bénin, Sud Niger)
2006
Le long de la bordure occidentale du bassin de Kandi, la sédimentation détritique continentale de base, correspondant à la formation de Wéré, est préservée dans des paléovallées limitées par des failles d'orientation moyenne N20°E, héritées de l'orogenèse panafricaine. Le remplissage sédimentaire de ces paléovallées est représenté par des dépôts conglomératiques et bréchiques de tills glaciaires marquant la base de la série, évoluant verticalement et latéralement vers l'Est à des grès fluviatiles. Ces dépôts continentaux, d'âge supposé ordovicien supérieur, passent verticalement à des grès tidaux et des grès et siltites subtidaux de la Formation de Kandi, d'âge ordovicien terminal à silurie…
High-rise timber architecture: an opportunity for the sustainability of the built environment
2019
Bioeconomy, circular economy, land use reduction, sustainable use of natural resources, reduction of CO2 emissions in the atmosphere and recycling are the keywords which the building world must face in the near future, as the environmental emergency can no longer be postponed. In order to disseminate in the scientific community the different possibilities of timber as a sustainable building material throughout its whole life cycle and to provide the professionals with suitable decision-making tools for a conscious design, within the cultural and scientific scenario of the recent years, the paper serves as a moment of reflection highlighting how a closer integration between different sectors…
