Life-cycle optimization of building performance: a collection of case studies
2023
The building sector is one of the most impacting on the energy demand and on the environment in developed countries, together with industry and transports. The European Union introduced the topic of nearly zero-energy building (nZEB) and promoted a deep renovations in the existing building stock with the aim of reducing the energy consumption and environmental impacts of the building sector. The design of a nZEB, and in general of a low-energy building, involves different aspects like the economic cost, the comfort indoor, the energy consumption, the life cycle environmental impacts, the different points of view of policy makers, investors and inhabitants. Thus, the adoption of a multicrite…
Sympathetic activation in patients with heart failure and central sleep apnoea: is it friend or foe?
2023
This sub-study of the SERVE-HF study found unchanged peripheral nervous sympathetic activity (MSNA) in heart failure patients on medical treatment or on ASV after 12 weeks. Reduced MSNA was associated with worse prognosis only in the ASV group
Monocyte Distribution Width (MDW) as a biomarker of sepsis: An evidenced-based laboratory medicine approach.
2023
Monocyte Distribution Width (MDW) is a new generation cell blood count parameter providing a measure of monocyte anisocytosis. In the last decades, it has emerged as a reliable biomarker of sepsis in the acute setting, especially emergency department, and intensive care unit. MDW has several advantages over commonly used sepsis biomarkers, including low-cost, ease and speed of measurement. The clinical usefulness of MDW has been established in several studies and some clinical laboratory medicines have already implemented it in their routine. In this article, we describe the analytical and clinical features of MDW to guide its appropriate use in clinical practice by integrating the research…
Certifying battery usage for V2G and second life with a blockchain-based framework
2023
This paper describes a blockchain-based approach for sharing data among all the actors involved in Vehicle-to-Grid programs. The shared information is used both for monitoring the health status of the vehicle’s battery and for remuneration in Vehicle-to-Grid programs. A blockchain platform and a set of appropriate smart contracts have been developed for supporting the interactions among the different actors and for creating battery usage profiles. To protect sensitive data, we limit the visibility scope of such data only to subsets of actors using blockchain channels. This approach preserves the privacy of the car owner on one hand and guarantees the compliance to correct charging and disch…
I criminalisti dello Stato della Chiesa. Famiglie, carriere e biblioteche (XVII secolo)
2023
Il volume affronta una figura chiave dell’immaginario penalistico di Antico regime, ovvero il giudice che amministra la giustizia nella stagione d’oro della criminalistica, quella, per intenderci, interpretata da un giurista del calibro, e della reputazione, di Prospero Farinacci. L’analisi si concentra, infatti, sul personale giusdicente che ha operato nei tribunali dello Stato della Chiesa nella prima metà del Seicento, tra i pontificati di Clemente VIII e Alessandro VII, in modo particolare sui giudici attivi presso le magistrature romane. L’indagine assume i tratti della ricerca prosopografica, attraverso lo spoglio di una documentazione d’archivio diffusa in diversi fondi dell’amminist…
Adsorptive Separation of CO2 by a Hydrophobic Carborane-Based Metal-Organic Framework under Humid Conditions
2023
We report that the carborane-based metal-organic framework (MOF) mCB-MOF-1 can achieve high adsorptive selectivity for CO2:N2 mixtures. This hydrophobic MOF presenting open metal sites shows high CO2 adsorption capacity and remarkable selectivity values that are maintained even under extremely humid conditions. The comparison of mCB-MOF-1' with MOF-74(Ni) demonstrates the superior performance of the former under challenging moisture operation conditions.
Quantum versus Classical Online Streaming Algorithms with Logarithmic Size of Memory
2023
We consider online algorithms with respect to the competitive ratio. Here, we investigate quantum and classical one-way automata with non-constant size of memory (streaming algorithms) as a model for online algorithms. We construct problems that can be solved by quantum online streaming algorithms better than by classical ones in a case of logarithmic or sublogarithmic size of memory.
Measuring higher-order cognitive skills with multiple choice questions:potentials and pitfalls of Finnish teacher education entrance
2023
This mixed methods study examines the structure of the multiple-choice exam for student selection in Finnish teacher education. Through qualitative content analysis, we categorized multiple-choice ques-tions into items that assessed lower-and higher-order cognitive processes based on the Revised Bloom's Taxonomy. Exploratory and confirmatory factor analyses yielded four factors that represented lower-and higher-order cognitive processing skills and comprehension of empirical and theoretical items. These were associated with matriculation examination grades, especially with the average grade and the mother tongue grade. When developing future multiple-choice exams for admissions, we recommen…
Are subjective outcomes a “missing link” between driving stress and risky driving behaviors of commuters? Assessing the case of a LMIC
2023
Despite the efforts made by different stakeholders, most of Low and Middle-Income Countries (LMICs) continue to systematically report very negative road safety outcomes. In fact, in countries like Colombia, the rate of deaths from traffic crashes has increased in recent years. One of the most affected collectives in this regard -and at the same time one of the least addressed in specialized literature- are driving commuters, which are commonly exposed to several types of threats and stressors configuring an “everyday risk” potentially impairing their health and safety. This study aimed to assess whether there exists an indirect path -mediated by subjective outcomes- linking driving stress a…
Effect of Mycorrhizal Inoculation on Melon Plants under Deficit Irrigation Regimes
2023
The shortage of good quantity and quality of water for irrigated agriculture is a major problem in arid and semiarid regions. To deal with this problem, deficit irrigation (DI) or arbuscular mycorrhizal fungi (AMF) inoculation have been proposed and adopted for many crops as a tool to save water, or to improve crop tolerance to drought stress. An experiment was conducted for two consecutive years to evaluate the effect of mycorrhizal inoculation on the physiological, morphological, yield, and quality characteristics of melon plants grown under deficit irrigation. Melon crop (Cucumis melo L. cv. Helios) was grown under field conditions adopting a split-plot design with four replications, whe…
Luminescent YPO4:Eu@PVA dispersions for anti-counterfeiting ink applications
2023
A method was developed to obtain YPO4:Eu dispersions of PVA as a luminescent inks. YPO4:Eu nanoparticles were prepared by precipitation followed by hydrothermal treatment. The dispersion preparation included systematic studies to prepare a stable colloidal system and to investigate the role of parameters affecting its stability and UV-excited YPO4:Eu emission intensity. The effect of PVA concentration was studied in detail for two different PVAs to determine the optimal parameters for its use as ink with specific luminescent properties. The type of interactions responsible for the dispersion stability was also investigated.
Design, mon amour
2023
Questo intrigante testo di Mariacarmela Scrudato, secondo me, non è risultato di un lavoro che si colloca nell’ambito della storia del design ma piuttosto nell’ambito della comunicazione della storia del design. Scrudato, infatti, non approfondisce un tema specifico della storia, non scende in verticale facendo ricerche puntuali. Non aggiunge conoscenza a quel che già abbiamo più volte letto nelle varie sto- rie. Eppure compie un lavoro eccellente: ricostruisce il percorso dando un senso tutto suo, volto a rendere agili e facilmente comprensibili argomenti complessi e a volte ostici. Ma soprattutto riesce a dare al tradizionale percorso storico un senso nuovo, tutto incentrato sull’attrazio…
Recovering ammonium by treated and untreated zeolitic mixtures: A comprehensive experimental and modelling study
2023
The recovery of ammonium (NH4+) from aqueous solutions by zeolite is attractive. In this study, the physicalchemistry of NH4+ adsorption process from aqueous solution by two zeolitic mixtures, either treated or not treated with NaCl, was assessed. Results suggested that the zeolitic mixture richer in mordenite and with high specific surface area adsorbed more NH4+ than the one richer in clinoptilolite and heulandite showing a lower specific surface area. NaCl treatment increased the amount of NH4+ adsorbed by the zeolitic mixtures. The higher amount of NH4+ adsorbed by the zeolitic mixtures treated with NaCl was explained by the low/high density water model accounting for cation exchange am…
Effectiveness of isolated vertical extension of masonry buildings as nonconventional TMD
2023
In this paper, the strategy of Intermediate Isolation System (IIS) is proposed for the vertical extension of an aggregate of masonry buildings located in Pozzuoli, south Italy. The effectiveness of IIS working as a nonconventional Tuned Mass Damper (TMD) for the existing construction is assessed in terms of reduction of seismic demand and damage in the masonry structure undergoing inelastic deformation under seismic input. For this aim, a general step-by-step procedure is first defined and then applied to the case study building. In particular, the characterization of dynamic behaviour and seismic capacity of the building aggregate is first addressed through modal and push over analyses. El…
Vibrational damping properties of finite microperforated plates
2023
Microperforated plates (MPP) are traditionally used to advantageously absorb acoustic waves in sound control technologies. However, less is known concerning the additional structural damping they can induce. The latter is activated through exchanges in the viscous and thermal boundary layers near the fluid-structure interface of the microperforations. MPPs therefore offer an alternative to, or can be used together with, viscoelastic materials, commonly implemented to damp vibrations at medium and high frequencies. In this work, the structural damping capabilities of MPP are investigated. To this end, the damping performance of a finite size MPP is explored analytically through an alternativ…
ADDISC lumbar disc prosthesis: Analytical and FEA testing of novel implants
2023
The intact intervertebral disc is a six-freedom degree elastic deformation structure with shock absorption. 'Ball-and-socket' TDR do not reproduce these properties inducing zygapophyseal joint overload. Elastomeric TDRs reproduce better normal disc kinematics, but repeated core deformation causes its degeneration. We aimed to create a new TDR (ADDISC) reproducing healthy disc features. We designed TDR, analyzed (Finite Element Analysis), and measured every 500,000 cycles for 10 million cycles of the flexion-extension, lateral bending, and axial rotation cyclic compression bench-testing. In the inlay case, we weighted it and measured its deformation. ADDISC has two semi-spherical articular s…
A computational and experimental investigation of halloysite silicic surface modifications after alkaline treatment
2023
Density functional theory calculations were performed in order to investigate the formation of silanol groups on the outer surface of halloysite nanotubes, as possible products of the reactions with water in alkaline environments. The results, discussed in terms of energy release and structural properties of the modified surface, suggest that the formation of various kinds of silanol group constellations, and even the extraction of orthosilicic acid, are highly exothermic reaction in the presence of hydroxide ions. Thermogravimetric analysis, FT-IR, XRD and X-ray fluorescence spectrometry performed on halloysite treated at high pH conditions indicate that the adsorption of water on the oute…
Clinical characteristics of pancreatic and biliary tract cancers in Lynch syndrome : A retrospective analysis from the Finnish National Lynch Syndrom…
2023
IntroductionPatients with Lynch syndrome (LS) have an increased lifetime risk of pancreatic cancer (PC) and biliary tract cancer (BTC). These cancers have a notoriously pessimistic prognosis due to late diagnosis and limited therapeutic options. There are limited data based on small cohorts reviewing PC and BTC in LS patients.MethodsIn this retrospective study of the Lynch Syndrome Registry of Finland (LSRFi), records of genetically verified LS patients diagnosed with PC or BTC between 1982 and 2020 were analyzed.ResultsThirty-nine patients were included: tumor(s) were in the pancreas in 26 patients, in the biliary tract in 10, and in the ampulla of Vater in three. A pathogenic germline var…
A Phenomenological Study About the Effect of Covid-19 Pandemic on the Use of Teaching Resources in Mathematics
2023
In this contribution, we discuss phenomenological research related to a pilot study carried out by the Consortium of the MaTeK Horizon 2020 project during the 2020–21 academic year. The research aims to analyse the effects of the Covid-19 pandemic on the use of teaching resources in mathematics in five coun- tries. A questionnaire made of seven questions was administered to a data sample made of teachers of all grades. The answers coming from the questionnaire were quantitatively and qualitatively analysed. Closed-ended questions were analysed by using a clustering methodology called k-means. Open-ended questions were qualitatively analysed. The results show that almost all the teachers are…
External sustainability in Spanish economy: bubbles and crises, 1970–2020
2023
We address the issue of the sustainability Spain’s exter-nal debt, using data for the period 1970–2020. To detect episodes of potentially explosive behavior of the Spanish net foreign assets over GDP ratio and the current account balance over GDP ratio, as well as episodes of external adjustments over this long period, we employ a recursive unit root test approach. Our empirical analysis leads us to conclude that there is some evidence of bubbles in the ratio between Spanish net foreign assets and the GDP. In contrast, the evidence that the ratio between the Spanish current account balance and the GDP had explosive subperiods is very weak. The episode of explosive behavior identified in the…
Voltammetric and electrodeposition study for the recovery of antimony from effluents generated in the copper electrorefining process
2023
Antimony is a metalloid with limited availability as a primary resource, but it is commonly found as an impurity in effluents generated in the copper metallurgy. Thus, the development of clean and selective processes to recover antimony from these wastewaters would improve the sustainability of the copper production. In this work, an emulated effluent of the copper electrorefining industry that contains antimony and hydrochloric acid was characterized by means of voltammetric and electrodeposition tests using two different cell configurations: a static cell, and a dynamic cell with a rotating disk electrode (RDE). Voltammograms were obtained at varying hydrochloric acid and antimony concent…
La tipografia e l’architettura non hanno mai smesso di amarsi
2023
Era appena ventottenne Victor Hugo quando scriveva con la sfrontatezza della sua giovane età quello che aveva dilatato a dismisura gli orizzonti della sua conoscenza, l’invenzione della stampa, il più grande avvenimento della storia, la rivoluzione madre che avrebbe consentito al pensiero umano di cambiare forma trovandone una nuova ed eterna.
Parte III – I fattori della produzione agricola: Capitolo VI, 6.1. Il lavoro in agricoltura
2023
Questo volume nasce dalla necessità di offrire una lettura contemporanea delle peculiari regole che tradizionalmente hanno attribuito al Diritto agrario un carattere di specialità. Facciamo riferimento alle norme che in un’ottica di programmazione di un settore produttivo centrale per l’economia del nostro paese disciplinano l’impresa agricola, la proprietà terriera, i contratti agrari, il lavoro agricolo, il credito agrario, il mercato dei prodotti agricoli. Regole la cui chiave di lettura è sempre passata dalla considerazione dell’esistenza di un legame stretto tra “agricoltura” e “terra”, considerazione che non riteniamo superata, ma piuttosto aggiornata, dalle numerose innovazioni legis…

On the variation of the correction factor of surface velocity with the measurement vertical for shallow flows over rough beds
2023
Considering that water flow energy affects the detachment of soil particles, the transport and deposit of the detached particles, the flow velocity is a key variable governing the soil erosion processes at the hillslope scale. The simple dye-tracer technique for measuring mean flow velocity can be applied in non-controlled field applications for which some measurement difficulties (e.g. due to sediment transport, and shallow flows) can occur. The correction factor is usually obtained as the ratio between the mean velocity, deriving from measurements of flow discharge and water depth, and surface velocity. Alternatively, the possibility of using the velocity profile in a given vertical to de…
Hydrogeochemical multi-component approach to assess fluids upwelling and mixing in shallow carbonate-evaporitic aquifers (Contursi area, southern Ape…
2023
With the aim of deepening our understanding of deep-seated fluids upwelling and mixing in large regional aquifers, we performed a hydrogeochemical study of twenty-two springs in the Contursi area (upper Sele river valley, southern Apennines) by means of the measurements of chemical-physical parameters, major ions, trace elements, and stable and radioactive isotopes. Besides, we realized two updated geo-structural cross-sections in order to reconstruct the groundwater flowpath in the study area. The hydrogeochemical composition, as well as the water temperature allow to identify-three main groups of groundwater: Cold and Low salinity Groundwater (CLGW), Intermediate Salinity Groundwater (ISG…
Extracellular vesicles and high‐density lipoproteins: Exercise and oestrogen‐responsive small RNA carriers
2023
Decreased systemic oestrogen levels (i.e., menopause) affect metabolic health. However, the detailed mechanisms underlying this process remain unclear. Both oestrogens and exercise have been shown to improve metabolic health, which may be partly mediated by circulating microRNA (c-miR) signalling. In recent years, extracellular vesicles (EV) have increased interest in the field of tissue crosstalk. However, in many studies on EV-carried miRs, the co-isolation of high-density lipoprotein (HDL) particles with EVs has not been considered, potentially affecting the results. Here, we demonstrate that EV and HDL particles have distinct small RNA (sRNA) content, including both host and nonhost sRN…
Towards Digital Twinning on the Web: Heterogeneous 3D Data Fusion Based on Open-Source Structure
2023
Recent advances in Computer Science and the spread of internet connection have allowed specialists to virtualize complex environments on the web and offer further information with realistic exploration experiences. At the same time, the fruition of complex geospatial datasets (point clouds, Building Information Modelling (BIM) models, 2D and 3D models) on the web is still a challenge, because usually it involves the usage of different proprietary software solutions, and the input data need further simplification for computational effort reduction. Moreover, integrating geospatial datasets acquired in different ways with various sensors remains a challenge. An interesting question, in that r…
Quale disciplina per la violazione di norme internazionali?
2023
In this chapter the traditional legal issues concerning the legal regime which applies to international law violations are described, according to an original perspective. First of all, some specific problems (such as the place of fault and damage; the moment in which a violation can be considered as being committed, and the conditions governing such a commission; the role to be recognized to countermeasure in the general framework of the legal consequences of internationally wrongful acts, etc.) are solved, at variance with the mainstream opinion. Second: the elements of an internationally wrongful act as well as its legal effects are both examined with regard to the general regime and som…
MATERNAL EXPOSURE TO STRESSFUL/TRAUMATIC EVENTS AND AUTISM SPECTRUM DISORDERS IN OFFSPRING: PRELIMINARY FINDINGS OF A CASE CONTROL PILOT STUDY.
2023
The correlation between maternal exposure to stressful and traumatic events during pregnancy and autism spectrum disorder (ASD) in offspring has been studied in the literature. Fewer studies, however, have considered the mother's exposure to traumatic events during childhood. This work focuses on maternal exposure to these events in childhood and/or adulthood, relating it to autism spectrum disorder in offspring. A questionnaire was used to assess whether and to what type of event the mothers have been exposed, and to assess eventual peri-traumatic dissociation related to the traumatic event. The mothers involved in this study were recruited at the Child Neuropsychiatry Outpatient Clinic of…
Future wood demands and ecosystem services trade-offs: A policy analysis in Norway
2023
To mitigate climate change, several European countries have launched policies to promote the development of a renewable resource-based bioeconomy. These bioeconomy strategies plan to use renewable biological resources, which will increase timber and biomass demands and will potentially conflict with multiple other ecosystem services provided by forests. In addition, these forest ecosystem services (FES) are also influenced by other, different, policy strategies, causing a potential mismatch in proposed management solutions for achieving the different policy goals. We evaluated how Norwegian forests can meet the projected wood and biomass demands from the international market for achieving m…

Sustainable recovery of critical elements from seawater saltworks bitterns by integration of high selective sorbents and reactive precipitation and c…
2023
The availability of raw mineral resources containing elements included in the Critical Raw Materials (CRMs) list is a growing concern for the European Union. Sea mining has been identified as a promising secondary source. In particular, brines obtained in solar saltworks (bitterns) contain relevant amounts of valuable CRMs such as Mg(II), B(III), other alkaline/alkaline earth metals (Rb(I), Cs(I), Sr(II)) and transition/post-transition elements (Co(II), Ga(III), Ge(IV)). However, the low concentration of some of these elements (µg/L) requires an effort to develop recovery routes that are sustainable and economically feasible where the required chemicals and energy are produced on-site from …
Spin Hyperpolarization in Modern Magnetic Resonance.
2023
Magnetic resonance techniques are successfully utilized in a broad range of scientific disciplines and in a number of practical applications, with medical MRI being the most widely-known example. Currently, both fundamental and applied magnetic resonance are enjoying a major boost owing to the dramatic signal enhancement provided by the rapidly-developing field of spin hyperpolarization. Such techniques are able to enhance signal intensities in magnetic resonance by several orders of magnitude, and thus to largely overcome its major disadvantage of relatively low sensitivity compared to other analytical techniques. This provides new impetus for existing applications, and, even more importan…
Distinguishing the Need to Belong and Sense of Belongingness: The Relation between Need to Belong and Personal Appraisals under Two Different Belongi…
2023
People are frequently caught in the hold between the need to belong and the fear of exclusion. However, these needs might be expressed differently under different belongingness conditions, where other powerful social processes are accentuated. Thus, the need to belong and social exclusion are concepts that are subjectively appraised based on one’s social relations. The present study aims to examine the relationship between the need to belong and five personal appraisals under two different belongingness conditions: (1) social-emotion support and (2) social-value representation. A total of 201 participants from two different groups were presented with 69 different items measuring five person…
