Il ‘campo' geografico di un'etnografia sottile. Cinque esperimenti di fieldwork
Authors: Valz Gris Alberto , Iacovone Chiara , Safina Astrid , Pollio Andrea , Governa Francesca
Published: March 2022

Negli ultimi 20 anni, esperienze e pratiche di ricerca etnografica si sono progressivamente affermate nella ricerca geografica fino a diventarne una componente fondamentale. Eppure ‘fare etnografia' in geografia non è certo né scontato: richiede un adattamento alle esigenze e agli obiettivi della riflessione geografica, ma anche alla complessità del ‘campo' della ricerca nelle scienze sociali contemporanee. In particolare, i tempi, i luoghi e le forme di un'etnografia thick (Geertz, 1973) sembrano inadatte a confrontarsi con le complessità spazio-temporali delle dinamiche socio-spaziali attuali, con le trasformazioni del campo di ricerca, del soggetto che fa ricerca e del contesto in cui si fa ricerca, ma anche, e più radicalmente, con i limiti derivanti dal retaggio coloniale della ricerca etnografica. Attraverso il riferimento a cinque radicalmente diverse esperienze di ricerca sul campo, l'articolo pone la questione del fare etnografia nella ricerca geografica ed esplora le possibilità di un suo ripensamento critico nella direzione di una positiva e necessaria sottigliezza e superficialità.
Green infrastructures for the energetic and environmental sustainability of cities
Authors: Di Lonardo Sara , Mariani Susanna , Giagnacovo Germina , Marone Antonella , Raimondi Salvatore
Published: March 2022

The inexorable extension of urbanization is consuming huge amounts of soil drastically reducing natural vegetation, replacing it with buildings and low albedo surfaces. The changes due to the different thermal properties of surface materials and the lack of evapotranspiration in urban areas lead to a phenomenon known as "urban heat island effect". By reintroducing the vegetation back into the urban landscape, a partnership between nature and cities should be strengthened to create a new sustainable urban environment. Since the outer surfaces of building offer a great amount of space for vegetation, planting on roofs and walls has become one of the most innovative way to provide several environmental services. Moreover, all the green infrastructures, such as urban gardens or nature areas, that form an important part of cityscapes, could ensure also a thermal isolation and constitute a sustainable energy saving solution for buildings. This work presents a critical review of environmental and potential thermal benefits of green infrastructures in the cities.

Published: March 2022

A sustainable and environmentally alternative to commonly used air conditioning systems can be the solar cooling system due to the use of renewable and clean energy. Solar absorption systems can be used for greenhouse cooling in areas with high outdoor temperatures and solar radiation levels. These systems take advantage of the simultaneity between the solar energy availability and the greenhouse cooling demand allowing the reduction of conventional electricity and water consumption. This paper presents the results of the application of a solar cooling plant for the climate control of a greenhouse at the University of Bari, Italy. The experimental plant consists of a Mediterranean greenhouse, having a surface of 300 m2, and of a single effect LiBr-H2O absorption chiller fed by evacuated-tube solar collectors. Two different localized systems were chosen for the distribution of cold inside the greenhouse: the first system presents pipes placed centrally on the cultivation vessels; the second consists of pipes in contact with aluminium plates and of a transparent EVA film, used to border an area close to plants. The distribution system of cold with pipes, plate and EVA film provided a slightly higher cooling capacity due to the presence of the plates which increases the ability to dissipate energy.

Published: March 2022

The need for energy-efficient buildings has emerged since the onset of the first energy crises in the 1970s. It's in this decade that the concepts of sustainable development and energy saving have been introduced in the construction sector. Currently, the greatest energy saving potential for buildings does not lie in new buildings, but in the energy redevelopment of existing buildings. In order to promote interventions for building restoration, which are often costly and not economically convenient, Italian legislation has made a series of economic incentives available to the sector. This work reviews the main incentive systems for the energy requalification of buildings.
Valorisation of urban green areas for producing renewable energy and biochar as growing substrate of Sicilian aromatic and nutraceutical species in a circular economy
Authors: Comparetti Antonio , Greco Carlo , Mammano Michele Massimo , Kestutis Navickas , Santo Orlando , Kestutis Venslauskas
Published: March 2022

This work is aimed at evaluating the possible building up of a gasifier for the energy valorisation of residual biomass deriving from urban areas and their surroundings. The area and the volumes of supply and economic convenience have been determined by implementing a GIS-based geographic method to the localisation and quantification of non-uniform elements of plant biomass. The pyrolysis and gasification processes of the lignocellulosic biomass obtained from pruning and maintenance operations of the urban and ornamental green include the production of a residual amount of biochar. The biochar can be used in agriculture as a soil improver and a substrate alternative to peat in the sustainable production of Sicilian aromatic and nutraceutical species grown in pots within a circular economy.
Manure as a potential source of renewable energy: The behaviour and characterisation of biofuels generated from three animal manure types when subjected to pyrolysis
Authors: Attard George , Alessandro Agnello , Comparetti Antonio , Fenech Oliver , Greco Carlo , Grima Connell Denise
Published: March 2022

Regions with high livestock density lack sufficient land on which to apply manure without exceeding the legal limits set by the European Union Directives. The lack of manure processing alternatives aggravates the situation, especially in the case of islands. Consequently, manure becomes a liability rather than an asset. Results indicate that pyrolysis is an option for manure processing. However, a significant limitation is the moisture content of the starting material, that could compromise the process efficiency. Yields of biogas, bio-oil and biochar, all of which have a potential use as biofuels, are particular to animal type and manure handling system. The conversion of manure to biofuels contributes to the development of a bio-based economy.
Operative and environmental performance of a hot-foam machine for the herbicide-free weeding of the vineyard
Authors: Facchinetti Davide , Bacenetti Jacopo , Eleonora Galli Lavinia , Luis Ruiz Garcia , Pessina Domenico
Published: March 2022

The elimination of chemical herbicides use is a key factor in vineyards, particularly in the case of biological cultivation. The machines employed for mechanical weeding under the vine row are often characterised by low travelling speeds and therefore also by a low working capacity. A new solution is the application of hot foam, to transmit heat to weeds. A hot-foam machine for the herbicide-free weeding of vineyards was then developed, to produce and deposit foam directly onto weeds. The foam strips produced were approximately 40 cm width and 20-25 cm height, with a temperature exceeding 75°C. The future success of this environmentally sustainable technique will be the identification of a 100% naturally biodegradable and long-lasting foam, to maximize heat transmission to weeds.
La terapia sistemica online: tecniche e strumenti
Authors: Risari Flavia
Published: March 2022

L'articolo esplora il tema della terapia sistemica svolta online prendendo in esame la letteratura a disposizione e svolgendo riflessioni a partire dall'esperienza dell'autrice. Vengono esaminate le ragioni per cui la terapia online è talvolta guardata con diffidenza e viene spiegato come questa possa invece essere tanto efficace quanto quella vis à vis e possa permettere ai pazienti di raggiungere il terapeuta anche quando lontani o impossibilitati a recarsi in studio. Attraverso l'analisi di alcuni casi clinici viene dunque descritto su un piano pratico come la terapia sistemica possa essere efficacemente condotta anche via video e vengono forniti alcuni spunti per il superamento di possibili ostacoli legati all'utilizzo degli strumenti tecnologici.

Authors: Romanenko I. , Trofymenko O. , Holiuk M. , Pysmennyy Y. , Nosovskyi A.
Published: March 2022

Незважаючи на усі переваги ядерної енергетики, проблемним питанням для атомної галузі залишається поводження з відпрацьованим ядерним паливом. На сьогодні як у світі, так і в Україні прийнята концепція «відкладеного рішення», згідно з якою відпрацьоване ядерне паливо тимчасово зберігається до моменту переробки з метою повторного використання або остаточного захоронення. В Україні реалізація цієї концепції відбувається за технологією тривалого «сухого» зберігання, розробленою компанією Holtec International («Холтек»). За цією технологією відпрацьоване ядерне паливо має зберігатися у спеціальних контейнерах під назвою HI-STORM, головним захисним бар'єром перед випромінюванням у яких є бетонний біологічний захист. У статі розглянуто можливість використання різних бетонів для біологічного захисту в контейнерах HI‑STORM для тимчасового зберігання відпрацьованого ядерного палива та забезпечення радіаційного захисту. Наведено рецептури покращеного бетону з гранітним щебенем, базальтовим щебенем та новим композитним матеріалом, армованим базальт-борною фіброю з різним додаванням концентрації оксиду бору.

За допомогою методу Монте-Карло коду Serpent виконано моделювання проходження нейтронного випромінювання через матеріали біологічного захисту. Показано, що додавання базальт-борної фібри в бетон покращує захисні властивості біологічного захисту від нейтронного випромінювання.

Authors: Marsena Jennifer Gracia , Angjaya Sonny
Published: March 2022

Social inequality has continuously become a problem especially towards marginalized group. Such topic is presented in Todd Phillips latest psychological thriller, Joker (2019). Whilst other researches focus on the psychological aspect of the film, this study takes on the perspective of the sociological/socio-political aspect in the film which is social inequality. In analyzing the social inequality aspect of the film, this study uses theory of structural discrimination by Link, et al. which theorizes that laws, policies, or other practices. are discriminating a marginalized group. To analyze the film itself, the writers analyzed the mise-en- scène and cinematography aspects of the film. The purpose of this study is to find if government’s policies have any involvement of impact to the life of a mentally ill person. Method used for this analysis is qualitative data research. In analyzing the film, it is found that Fleck’s life as a mentally ill and poor person is deliberately sabotaged by the discriminative policies and laws applied in Gotham city. In conclusion, this film represents Joker as more than just a Batman’s main film but rather used as a vehicle to criticize the state of social inequality in the world.

In late 2019, a new type of coronavirus emerged in China and was named SARS-CoV-2. It first impacted the country where it emerged and then spread around the world. SARS-CoV-2 is the cause of COVID-19 disease that leaves characteristic impressions on chest CT images of infected patients. In this article, we propose a classification model, based on CNN and wavelet transform, to classify images of COVID-19 patients. It was named WCNN-COVID. The model was applied and tested in open and private TC image repositories. A total of 25534 images of 200 patients were processed. The confusion matrix was generated by calculating Accuracy (ACC), Sensitivity (Sen) and Specificity (Sp). The Receiver Operating Characteristic (ROC) curve and Area Under the Curve (AUCs) were also plotted and used for evaluation. Metric results were ACC = 0.9950, Sen = 99.16% and Sp = 99.89%.

Authors: Toro Ana Paola Salas Gomes Duarte Di , Cardoso-Leite Eliana , Valente Roberta Averna
Published: March 2022

Atlantic forest fragmentation is considered a serious threat to biodiversity since this biome is considered the hottest hotspot. Due to this reason, many environmental strategies are being developed in order to support its, one of them being the prioritization of forest remnants using landscape ecology metrics. Thus, the main objective of this study is the development of a patches prioritization index (PPI) in order to support conservation actions and research. Firstly, a diagnosis of forest remnants in the study area was performed using landscape ecology metrics. Secondly, by literature review and expert consulting, were selected the adequate landscape ecology metrics, next, their importance was determined for PPI composition. Selected landscape metrics (AREA, SHAPE, and NEARD) composed the PPI. Finally, using a rapid ecological assessment (BII) the PPI was validated in the field. The results showed that the study area has patches able to aid biodiversity maintenance in the landscape.  Further, the selection and importance attributed to landscape ecology metrics were demonstrated to be adequate. Also, the index is accurate enough to identify priority patches, classes, and regions for biodiversity conservation. Finally, the validation of PPI in the field showed that PPI is effective to estimate patches integrity in the field. In conclusion, our results suggest that PPI could be used for the prioritization of Atlantic forest remnants in a landscape covered mainly by Atlantic forest remnants and agriculture.

STUDENTS’ PROBLEMS ON BLENDED LEARNING PRACTICE: A CASE STUDY AT ELEMENTARY SCHOOL IN A NEW NORMAL OF COVID-19
Authors: Zulpadli Lalu , Embong Rahimah
Published: March 2022

Up to now, no one can predict when the COVID-19 outbreak will end. Education as one of the affected sectors is necessary to adjust to existing conditions in what we call a new normal. The learning process in the new normal is much different from previous learning because it should follow any stipulation including school should obey health protocols, the number of students is not more than half the capacity of the classroom, the face-to-face learning in class is reduced to half of the available time. Blended learning is chosen as a learning strategy to be applied in elementary school. The sudden application of blended learning strategy in elementary schools raises many problems, including those faced by students.
