Sound perception of different materials for the footpaths of urban parks
No full textOver the years the environmental potential of urban parks has attracted increasingly attention. In order to preserve their positive influence for communities, the sonic environment perception (soundscape) must be considered too. Urban parks' sonic environment is influenced by attenders moving around; indeed, walking sounds have very high occurrence in such contexts. However, studies investigating both walking sounds and soundscape are limited. This study investigates the influence of different footpath materials on the sonic perception. A laboratory listening experiment was carried out with four walked-on materials: grass, wood, stone and gravel. Preliminary results show a significant material effect on soundscape perception
The effect of walking sounds from different walked-on materials on the soundscape of urban parks
No full textUrban parks are essential environmental resources in contemporary cities, for the substantial social and psychological relief they provide for local communities. In recent years, the potential of the soundscape approach for enhancing the ecological contribution of such environmental assets has been intensely investigated. Although, researchers tended to focus on the perception of people “staying” in the park, whilst it is important to consider how the sonic environment would be dynamically perceived by users walking across the park. Within this framework, the present study aimed to investigate the effect of different footpath materials on soundscape quality and walking quality perception for people walking in an urban park, considering that the experience of such users is affected by both the background acoustic environment of the park and their walking sound. To this purpose, a laboratory experiment was carried out with 25 participants. Four different walked-on materials that are likely to be used in urban parks were tested: grass, wood, stone and gravel. Results show that the material factor has a significant effect on both auditory and haptic perception. Furthermore, positive correlations can be observed between auditory and haptic variables, confirming that the soundscape appreciation for people walking in urban parks is likely to be affected also by other but aural sensory modalities. The paper ultimately points out that it is possible to re-think the approach to urban parks design and more specifically to the footpaths and the walking sounds that their materials are likely to produce
Differences in soundscape appreciation of walking sounds from different footpath materials in urban parks
No full textThe perception of the acoustic environment, namely the soundscape, in urban parks has attracted increasing attention. There is a growing belief that the management of the acoustic environment of urban parks should be addressed within a broader soundscape methodology rather than a merely noise control one. One of the most frequent sound sources in urban parks is walking sound; however walking sound perception so far has mainly been investigated for indoor environments. This paper aims to investigate the overall effect of walking sounds from different walked-on materials on people's soundscape, combined with other non-acoustical factors. Moreover, this research investigates how perception varies when the walking sound is self-produced or simply listened. To this purpose, two laboratory experiments in Italy and UK were carried out with four walked-on materials that were considered to be possible design solutions for the footpaths of urban parks: grass, wood, stone and gravel. Results showed a significant effect of materials on perceived noise annoyance and soundscape quality, as well as a partial influence of other nonacoustical factor. Considering the individual responses for the four selected materials, gravel was associated to the worst soundscape quality (M = 38.42) while grass to the best one (M = 65.05). While a group effect (Italian and UK samples) was observed for perceived noise annoyance corresponding to the materials, no significant group effect was found for soundscape evaluation. Eventually, people simply listening to the walking sounds resulted to be less tolerant towards them, with respect to people who self-produced the sounds by walking

Impact of age and gender on glioblastoma onset, progression, and management
No full textGlioblastoma (GBM) is the most common primary malignant brain tumor in adults, while its frequency in pe-diatric patients is 10-15%. For this reason, age is considered one of the major risk factors for the development of GBM, as it correlates with cellular aging phenomena involving glial cells and favoring the process of tumor transformation. Gender differences have been also identified, as the incidence of GBM is higher in males than in females, coupled with a worse outcome. In this review, we analyze age-and gender-dependent differences in GBM onset, mutational landscape, clinical manifestations, and survival, according to the literature of the last 20 years, focusing on the major risk factors involved in tumor development and on the mutations and gene alter-ations most frequently found in adult vs young patients and in males vs females. We then highlight the impact of age and gender on clinical manifestations and tumor localization and their involvement in the time of diagnosis and in determining the tumor prognostic value

Abstract
The COVID-19 health emergency has imposed the need to limit and/or stop non-essential economic and commercial activities and movement of people. The objective of this work is to report an assessment of the change in vehicle flows and in air quality of a specific study area in the north of Italy, comparing the periods February–May 2020 and February–May 2019. Circulating vehicles have been measured at nine characteristic points of the local road network of the city of Reggio Emilia (Italy), while atmospheric pollutant concentrations have been analysed using data extracted from the regional air quality monitoring network. The results highlight a rapid decline in the number of vehicles circulating in 2020 (with values of up to −82%). This has contributed to a reduction in air concentrations of pollutants, in particular for NO2 and CO (over 30% and over 22%, respectively). On the other hand, O3 has increased (by about +13%), but this is expected. Finally, the particulate matter grew (about 30%), with a behaviour similar to the whole regional territory. The empirical findings of this study provide some indications and useful information to assist in understanding the effects of traffic blocking in urban areas on air quality

Il terzo capitolo è dedicato all’illustrazione delle due opere. Nel quarto capitolo si procede all’analisi e al confronto. Nell’ultimo capitolo si presentano alcune considerazioni sul metateatro, sulla trama, sui personaggi e sui temi principali dell’Alcesti di Samuele.
The aim of this work is to compare the Greek tragedy Alcesti by Euripides, performed on stage in 438 B.C., with the Alcesti di Samuele by Alberto Savinio, first performed at the Piccolo Teatro in Milan in 1950. The first chapter provides biographical information about the Author. The second chapter collects and describes the works about the character of Alcesti published by Savinio on newspapers and examines the sources of the play. The third chapter is about the description of the two works. The fourth chapter contains their analysis and comparison. In the last chapter some considerations about metatheatre and about the plot, the characters and the main themes of the Alcesti di Samuele are carried out
Manutenção da crista óssea alveolar a longo prazo em implantes cone-morse e hexagonal externo : revisão sistemática
No full textIntrodução: A manutenção óssea peri-implantar representa hoje em dia um tema de debate
interessante enquanto esta intimamente ligado ao prognostico das reabilitações protéticas
implanto-suportadas. A estrutura implantar bem como o tipo de conexão implante-pilar, são
fatores que podem contribuir a perda óssea peri-implantar e afetar negativamente o
prognostico do tratamento. Os dois desenhos de implante-pilar mais utilizados atualmente
são a ligação hexagonal externa e a ligação morse.
Objetivo: avaliar o nível de evidência científica sobre a manutenção da crista óssea
alveolar e os parâmetros clínicos associados, após a colocação de implantes cone-morse
e hexagonal externo, de modo a alcançar a previsibilidade clínica sobre o tema abordado.
Materiais e métodos: A literatura considerada para esta revisão sistemática é baseada
nas diretrizes PRISMA e visou responder a seguinte questão específica construída no
formato PICO: “Para pacientes tratados com implantes dentários (P), seja conexão externo
(I) ou cone-morse (C), existem diferenças na manutenção da crista óssea após pelo menos
seis meses em função (O)? Foi realizada uma pesquisa eletrónica nas bases de dados
MEDLINE®/Pubmed, Embase e Wiley a fim de identificar estudos clínicos comparando a
perda óssea em torno de implantes hexágono esterno e cone-morse com um período de
acompanhamento mínimo de seis meses. Os dados obtidos a partir dos estudos incluídos
foram extraídos e analisados através de uma meta-análise de modelo de efeitos aleatórios
contínuos. A variável primária utilizada foi a perda óssea marginal.
Resultados: A pesquisa inicial identificou 110 artigos. No entanto, 6 artigos foram
considerados adequados após a leitura do texto completo e foram incluídos no estudo. A
literatura analisada revelou uma diferença na perda óssea peri-implantar nos dois tipos de
conexões analisados (p< .001). Os parâmetros clínicos secundários e a sobrevivência
implantar associada aos dois tipos de ligação não revelaram diferencias significativas.
Conclusão: Os resultados da presente revisão sistemática sugerem que a manutenção
óssea marginal é maior em implantes com uma conexão morse. Contudo, devido ao número
limitado de estudos clínicos incluídos nesta revisão, os dados devem ser analisados com
cuidado. Portanto, necessárias mais investigações, incluindo um maior número de
pacientes, um tempo de seguimento mais longo e um controlo adequado dos fatores de
confusão.Introduction: Peri-implant bone maintenance represents an interesting topic of debate as
it is closely linked to the prognosis of implant-supported prosthetic rehabilitations. The
implant structure as well as the type of implant-abutment connection are factors that can
contribute to peri-implant bone loss and negatively affect treatment prognosis. The two most
used implant-abutment designs today are the external hexagon connection and the morsetaper connection.
Objective: Evaluate the level of scientific evidence on alveolar crestal bone maintenance
and associated clinical parameters after placement of morse taper and external hexagon
implants, to achieve clinical predictability on the topic addressed.
Materials and methods: The literature considered for this systematic review is based on
PRISMA guidelines and aims to answer the following specific question constructed in PICO
(Population, Intervention, Control, Outcomes) format: "For patients treated with dental
implants (P), either external connection (I) or morse taper (C), are there differences in bone
crest maintenance after at least six months in function (O)? An electronic search in
MEDLINE®/Pubmed, Embase and Wiley databases was performed to identify clinical
studies comparing bone loss around external hexagon and morse taper implants with a
minimum follow-up period of six months. The data obtained from the included studies were
extracted and analyzed using a continuous random effects model meta-analysis. The
variable used was marginal bone loss.
Results: The initial search identified 110 articles. However, 6 articles were considered
adequate after reading the full text and were included in the study. The literature reviewed
revealed a difference in peri-implant bone loss in the two types of connections analyzed
(p< .001). The secondary clinical parameters and implant survival associated with the two
connection types revealed no significant differences.
Conclusion: The results of the present systematic review suggest that bone maintenance
is higher for implants with a cone-morse connection. However, due to the limited number of
clinical studies included in this review, it is suggested to take care with the interpretation of
the results. Further investigations are therefore needed, including a larger number of
patients, a longer follow-up time and adequate control for confounding factors
