New Metropolitan Perspectives Transition with Resilience for Evolutionary Development
2023
This open access book conveys attention to the theme of transition towards resilience and sustainability and its evolutionary perspective that emphasizes the complexity and uncertainty that governments and society are called to address in response to the ongoing challenges. "New Metropolitan Perspective Post COVID Dynamics: Green and Digital Transition, between Metropolitan and Return to Villages’ Perspectives”, 25–27 May 2022, Reggio Calabria, Italy. The papers included in the book are grouped around the following main topics: the envisaged transition towards resilience and sustainability; the relevance of the planning dimension for defining sustainable development pathways and managing co…
Safety of hospital discharge before return of bowel function after elective colorectal surgery
2020
Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…
Developing Primary School Students’ Formal Geometric Definitions Knowledge by Connecting Origami and Technology
2019
In this paper, we present opportunities with the uses of origami and technology, in our case GeoGebra, in teaching formal geometric definitions for fifth-grade primary school students (11-12yrs). Applying origami in mathematical lessons is becoming to be recognized as a valuable tool for improving students’ mathematical knowledge. In previous studies, we developed origami and technology activities for high-school mathematics, but we wanted to explore if such approach would work in primary school as well. For this reason, we chose a flat origami model оf the crane and we used this model to introduce students to basic geometrical notions and definitions, such as points, lines, intersections o…
Effect of Germacrene-Rich Essential Oil of Parentucellia latifolia (L.) Caruel Collected in Central Sicily on the Growth of Microorganisms Inhabiting…
2022
In the present study, the chemical composition of the essential oil from aerial parts of Parentucellia latifolia (L.) Caruel collected in Central Sicily was analyzed by gas chromatography and gas chromatography–mass spectrometry. The results showed the presence of sesquiterpene hydrocarbons, with germacrene D and germacrene B accounting, respectively, for 59.2% and 24.3% of the total oil. Different colonies of bacteria and fungi frequently affect cellulosic objects such as books stored in libraries and museums. The antibacterial and antifungal activity against some microorganisms infesting historical-artistic craftsmanship was determined, demonstrating that the essential oil was particular…
Uniqueness, reconstruction and stability for an inverse problem of a semi-linear wave equation
2022
We consider the recovery of a potential associated with a semi-linear wave equation on Rn+1, n > 1. We show that an unknown potential a(x, t) of the wave equation ???u + aum = 0 can be recovered in a H & ouml;lder stable way from the map u|onnx[0,T] ???-> (11, avu|ac >= x[0,T])L2(oc >= x[0,T]). This data is equivalent to the inner product of the Dirichlet-to-Neumann map with a measurement function ???. We also prove similar stability result for the recovery of a when there is noise added to the boundary data. The method we use is constructive and it is based on the higher order linearization. As a consequence, we also get a uniqueness result. We also give a detailed presentation of the forw…
Heart Rate Variability Monitoring During Strength and High-Intensity Interval Training Overload Microcycles
2019
Objective: In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval training (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) and vagal heart rate variability (HRV). Methods: In the study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 female, 9 male) were subjected to orthostatic tests (HR and HRV recordings) each day during a 4-day baseline period, a 6-day overload microcycle, and a 4-day recovery period. Discipline-specific performance was assessed before and 1 and 4 days after training. Results: Following ST overload, supine HR, and vagal HRV (Ln RMSSD) were clearly increased and decreased (small …
Combustion behavior of black liquors : droplet swelling and influence of liquor composition
2017
The combustion of black liquor (BL) in a recovery boiler is a central process in a kraft pulp mill for recovering the cooking chemicals and for producing heat and power. This work explored the most important combustion behavior of BL, the swelling of in-flight droplets, from the viewpoint of liquor composition. It also studied the combustion behavior of BL droplets obtained from two biorefining subprocesses (carbonation and hot-water pretreatment, HWP) and sulfur-free pulping alternatives (soda-anthraquinone (AQ) and oxygen-alkali pulping). The formation of a plastic state essential for the swelling of BL droplet was found to result from the melting of an array of carbohydrate-derived aliph…
Energetic demands and nutritional strategies of elite cross-country skiers during Tour de Ski : A narrative review
2021
The Tour de Ski (TDS: 6–9 sprint and distance races across 9–11 days) represents the most intense competition series of the cross-country (XC) ski season and is characterized by accumulated stress from consecutive days of high-intensity (~ 85%–160% VO2max) racing, travel, cold temperatures and low to moderate altitude (500–1500 m above sea level). Here, nutritional strategies play a key supportive role for optimized health, recovery and performance. This narrative review aims to provide an evidence-based discussion on the energetic demands of the TDS and recommendations for nutritional strategies to optimize health and performance of XC skiers during and following the TDS. We highlight seve…
Ohjausvuorovaikutuksen laatu ja esiopettajien työhyvinvointi: kontekstitekijöiden ja työstä palautumisen merkitys
2022
Tämän tutkimuksen tavoitteena oli selvittää, missä määrin ohjausvuorovaikutuksen laatu ja esiopettajien työhyvinvointi (koettu stressi ja työstä palautuminen) vaihtelevat suhteessa esiopetuksen kontekstitekijöihin eli esiopetuksen toteutuspaikkaan (päiväkoti tai koulu), ryhmäkokoon ja esiopettajan työkokemukseen. Lisäksi selvitettiin, muuntaako esiopettajien työstä palautuminen ohjausvuorovaikutuksen laadun ja koetun stressin välisiä yhteyksiä esiopetusvuoden aikana. Tutkimukseen osallistui 47 esiopettajaa esiopetusvuoden syksyllä ja keväällä. Ohjausvuorovaikutuksen laatua arvioitiin CLASS Pre-K –havainnointityökalun avulla kolmella osa-alueella: tunnetuki, toiminnan organisointi ja ohjauks…
PNRR E RIFLESSI SULLA FORMA DI GOVERNO ITALIANA. UN RITORNO ALL'INDIRIZZO POLITICO NORMATIVO?
2021
The work intends to analyse the impact on the governance of the decision-making, implementation and monitoring process of the PNRR. Starting from the «Dispositive» for recovery and resilience, one of the Next Generation EU most important instruments, from the relative negotiations and the European regulatory background, the paper briefly describes the procedural and content profiles of the PNRR drawn up by the Italian government in order to investigate the effects that this may have on the dynamics of the form of government and therefore also on the relations between the executive and the legislative, and in particular on which role the Parliament will be able to define for itself. The fil …
