Comparing the environmental performances of new and renovated school buildings

Evaluating which is the best choice between renovating an existing construction or building a new structure in countries like Italy, where a huge post-war un-listed building heritage does not satisfy the current standards and the economic resources are limited, is not trivial. Several parameters come into play, such as such the extent of the construction work, the environmental cost of disposing old materials, the carbon footprint and volume of new materials. This paper is devoted to the analysis of two projects. The first consists of a renovation of a multi-storey existing school built in 1960s having total area of about 9900 m2. The second is a new construction of a three-story school having a total area of about 14000 m2 and made with timber. The results show that the existing school building, although having a lower embodied carbon related to materials, has a higher overall carbon footprint due to the CO2 emissions related to operational energy

Thermal Energy Storage as a Way to Improve Transcritical CO2 Heat Pump Performance by Means of Heat Recovery Cycles

Electrification of the heating sector is a major target of energy transition towards a more sustainable, efficient, and less polluted future. Heat pumps are considered more suitable than electrical heaters or fossil-fueled boilers; however, common refrigerants cause ozone layer depletion, which exacerbates the greenhouse effect. Natural refrigerants, such as CO2, perform comparably and even better than hydrofluorocarbons while minimizing the negative aspects. This study presents a model of a water-heater CO2 transcritical heat pump in a configuration that increases the overall coefficient of performance (COP) by introducing thermal energy storage (TES). The thermodynamic cycle was divided into two separate phases. After heating the TES (charging), warm water was used as the heating fluid in the evaporator to increase the evaporation temperature and pressure of CO2, which reduced the work of the compressor. As the water temperature decreased progressively, the discharge cycles improved the total COP. The case study focuses on dairy processes and suggests a more straightforward and cheaper method to improve cycle efficiency than the current processes, such as ejector-expansion systems or double compression

Mechanical and Environmental Proprieties of {UHP}-{FRCC} Panels Bonded to Existing Concrete Beams

Among the techniques used to retrofit existing reinforced concrete structures, methods involving Ultra High Performance Fiber Reinforced Cementitious Composites (UHP-FRCC) are widely regarded. However, current practices make the use of this material for in-situ application expensive and complicated to perform. Accordingly, a new method to strengthen existing concrete beams by applying a precast UHP-FRCC layer on the bottom side are introduced and described herein. Two test campaigns are performed with the aim of defining the best conditions at the interface between the reinforcing layer and the existing beam and to reducing the environmental impact of UHP-FRCC mixtures. As a result, the eco-mechanical analysis reveals that the best performances are attained when the adhesion at interface is enhanced by means of steel nails on the upper surface of the UHP-FRCC layer, in which 20% of the cement is replaced by fly ash

Failure in reflective functioning as a key factor in the association between problematic social networking sites use, attachment and childhood maltreatment: A network analysis approach on gender differences

Following a network analysis approach, the present study aims to explore the pattern of mutual relationships between failure in reflective functioning (RF) - defined as hypomentalization - problematic social networking sites use (PSNSU), attachment anxiety and avoidance, and childhood maltreatment among emerging adults, with a focus on gender differences. The study sample comprises N = 1,614 emerging adults (Mage = 23.84; SD = 3.21; 50% identified themselves as women) who completed online self-assessment measures. Results showed significantly greater PSNSU, hypomentalization, childhood emotional abuse, and both attachment avoidance and anxiety among women. Indeed, within the network analysis, performed separately for men and women, network-specific associative patterns were observed; yet also similarities have emerged. Within the women's network, differently from males, attachment avoidance connects, through attachment anxiety, to emotional abuse, mood modification related to PSNSU, and hypomentalization. Nonetheless, hypomentalization was central in both networks, functioning as a hub between attachment anxiety, the PSNSU cluster, and the childhood maltreatment cluster. These results shed light on the use of social network sites as a potential maladaptive emotion regulation strategy, particularly among women. In this regard, the role of RF should be considered as a key treatment target to reduce PSNSU and support the use of adaptive emotion regulation strategies

Experimental and Numerical Analysis of the Hydrodynamics around a Vertical Cylinder in Waves

The present study provides an extensive analysis on the hydrodynamics induced by a vertical slender pile under wave action. The authors carried out the study both experimentally and numerically, thus enabling a deep understanding of the flow physics. The experiments took place at a wave flume of the Universita Politecnica delle Marche. Two different experimental campaigns were performed: In the former one, a mobile bed model was realized with the aims to study both the scour process and the hydrodynamics around the cylinder; in the latter one, the seabed was rigid in order to make undisturbed optical measurements, providing a deeper analysis of the hydrodynamics. The numerical investigation was made by performing a direct numerical simulation. A second order numerical discretization, both in time and in space, was used to solve the Navier-Stokes equations while a volume of fluid (VOF) approach was adopted for tracking the free surface. The comparison between experimental and numerical results is provided in terms of velocity, pressure distributions around the cylinder, and total force on it. The analysis of the pressure gradient was used to evaluate the generation and evolution of vortices around the cylinder. Finally, the relation between scour and bed shear stresses due to the structure of the vortex pattern around the pile was assessed. It is worth noting that the physical understanding of this last analysis was enabled by the combined use of experimental data on scour and numerical data on the flow pattern

Nutritional composition of raw and fried big-scale sand smelt (Atherina boyeri) from Trasimeno lake

The aim of this research was to investigate the nutritional composition of raw and fried big-scale sand smelt (Atherina boyeri) from Trasimeno Lake. Four hundred big-scale sand smelts were caught with nets and analysed immediately. We created a total of 20 batches with 20 whole fish in each batch. Ten batches were analysed as raw samples, while the other 10 batches were analysed after being fried in sunflower oil at a temperature of 190 °C for 3 min (deep fat frying). The pH, proximate composition, fatty acid profile, oxidative stability and nutritional indexes of both groups were assessed. As expected, cooking strongly influenced the characteristics of the meat, mainly in terms of lipids, which were seven times greater in the fried product due to the oil. Frying also affected the fatty acid profile of the meat because oil absorption caused a significant increase in oleic and linoleic acids. Furthermore, we found a slight reduction in long chain n-3 fatty acids (eicosapentaenoic and docosahexaenoic acids). Frying increased oxidative processes and decreased the nutritional value of sand smelt. The obtained results can be considered preliminary because the effects of the fishing season and different physiological phases of sand smelt require further analytical confirmation.Highlights The aim of the research was to investigate the nutritional composition of raw and fried big-scale sand smelt (Atherina boyeri) from Trasimeno Lake. The fried big-scale sand smelt had a meat lipids content 7-times greater than the control, due to the oil adsorbition. Frying increased oxidative processes and decreased the nutritional value of big-scale sand smelt

Impact of ozone and UV irradiation sanitation treatments on the survival of Salmonella and the physical–chemical characteristics of hen eggs

Summary: Salmonella is the second main cause of foodborne illness in poultry production. It is one of the most problematic zoonoses in terms of public health worldwide because of the difficulty in controlling it and its significant morbidity and mortality rates. Recent surveys have shown that small flocks of laying hens have the same or higher prevalence of salmonellosis than larger flocks, mainly due to a lack of control actions, that is, the control of mice and wild animals, employees, and poor management practices. In this regard, different physical and chemical procedures have proven efficacious for reducing external and/or internal Salmonella contamination. This research evaluated the effect of ozone and UV-C rays on Salmonella growth and hen egg quality. Microbiological evaluation was performed on 120 eggs: negative control (C−), eggs not contaminated with Salmonella; positive control (C+), eggs contaminated; contaminated ozonate-treated (O, 600 mg/h for 2 h); and contaminated UV-C–irradiated (ʎ, 254 nm for 15 s) eggs. Moreover, 30 eggs were used (10/group) for the quality assessments of the C, O, and UV-C groups. A 2 log10 CFU/g reduction in Salmonella on contaminated eggs was found in the UV-C group compared with the C+ and O groups. Compared with UV-C treatment, ozonization reduced the amount of yolk tocols and carotenoids (by 2 times). The lipid oxidative status decreased (−1.5 times), similar to the cholesterol level (−28.5%), whereas the amount of cholesterol and its oxidized products increased (+82.1%) in the O group compared with the C group. UV-C irradiation is an effective strategy to reduce Salmonella contamination in eggs without negatively affecting the quality. Therefore, UV treatments remain among the more promising procedures

Unified incremental nonlinear controller for the transition control of a hybrid dual-axis tilting rotor quad-plane

Overactuated Tilt Rotor Unmanned Aerial Vehicles are renowned for exceptional wind resistance and a broad operational range, which poses complex control challenges due to non-affine dynamics. Traditional solutions employ multi-state switched logic controllers for transitions. Our study introduces a novel unified incremental nonlinear controller for overactuated dual-axis tilting rotor quad-planes, seamlessly managing pitch, roll, and physical actuator commands. The control allocation problem is addressed using a SQP iterative optimization algorithm, well-suited for nonlinear actuator effectiveness in thrust vectoring vehicles. The controller design integrates desired roll and pitch angle inputs. These desired attitude angles are autonomously managed by the controller and then conveyed to the vehicle during slow airspeed phases, when the vehicle maintains its 6 DOF. We incorporate an AoA protection logic to prevent wing stall and a yaw rate reference model for coordinated turns. Flight tests confirm the controller's effectiveness in transitioning from hovering to forward flight, achieving desired vertical and lateral accelerations, and reverting to hovering
