Abstract Specimens for x-ray fluorescence analysis (XRFA) were prepared by adding dry gelatine (10%) to the analysis solution, homogenizing the mixture and cooling for 20 minutes. Thus, a compact resilient mass could be formed with the required shape and size; the roughness of the surface was determined by the roughness of the surface on which the specimen was formed, much the same as highly polished. Various calibration methods can be applied in the XRFA of a variety of materials if such specimens are used.

Full textAbstract:
In recent years, most cities have experienced rapid population growth. Concurrently, international policies have called for substantial reductions of greenhouse gas emissions. Additionally, the resilience of energy-supply systems has become more important. Consequently, solutions to exhaust locally-available sources must be developed to minimize the fraction of fossil fuels for heating, cooling and electricity. This article shows an example of designing a low-temperature heating and cooling grid based on locally-available renewables and waste heat and introduces general hypotheses concerning smart energy planning in urban development zones. Taking an urban development area in Vienna, Austria, as example, it is shown that wastewater, geothermal and (office) waste heat, solar energy, and the heat content of ambient air can play an important role within a climate-friendly urban energy concept and that heating and cooling demand can be covered completely on-site. From an environmental point of view, the concept is promising, as greenhouse gas emissions and the non-renewable primary energy consumption can be reduced by over 70% compared to conventional gas heating, while, based on current (fossil) energy prices, it is economically not fully competitive. The gap could be closed e.g. by CO2 taxes on fossil energy sources or (temporal) subsidies for renewables. Additionally, reservations of stakeholders in the energy sector against this innovative approach must be dismantled.

Urban rooftops are a potential source of water, energy, and food that contribute to make cities more resilient and sustainable. The use of smart technologies such as solar panels or cool roofs helps to reach energy and climate targets. This work presents a flexible methodology based on the use of geographical information systems that allow evaluating the potential use of roofs in a densely built-up context, estimating the roof areas that can be renovated or used to produce renewable energy. The methodology was applied to the case study of the city of Turin in Italy, a 3D roof model was designed, some scenarios were investigated, and priorities of interventions were established, taking into account the conditions of the urban landscape. The applicability of smart solutions was conducted as a support to the review of the Building Annex Energy Code of Turin, within the project ‘Re-Coding’, which aimed to update the current building code of the city. In addition, environmental, economic, and social impacts were assessed to identify the more effective energy efficiency measures. In the Turin context, using an insulated green roof, there was energy saving in consumption for heating up to 88 kWh/m2/year and for cooling of 10 kWh/m2/year, with a reduction in greenhouse gas emissions of 193 tCO2eq/MWh/year and 14 tCO2eq/MWh/year, respectively. This approach could be a significant support in the identification and promotion of energy efficiency solutions to exploit also renewable energy resources with low greenhouse gas emissions.

Full textAbstract:
South Asia, with more than one-fifth of the world’s population, is highly vulnerable to heatwaves and associated health consequences. The population experiences considerably higher residential vulnerability due to limited infrastructural capacities, economic resources, and health and environmental quality deficiencies. However, a limited number of studies are available from the region to account for the health effects of heatwaves. Therefore, this study has conducted a comprehensive review to characterize heatwaves across South Asian countries. The review explicitly identifies the population’s vulnerability to heatwaves during recent years and heatwave management policies in the region. The literature review suggests increased heat-related deaths in most South Asian countries, with few exceptions. In addition, the analysis of historical temperature records identified an upward trend in annual average temperature across the South Asian countries. The study highlights various heatwave definitions that have been used in the region to facilitate comparative evidence. The review of policies identified that only a few South Asian countries have functional heatwave management plans and majorly lack community and residential preparedness for heatwaves. Therefore, this study identifies potential community- and residential-based adaptation strategies to mitigate heat discomfort. As prospective solutions, the study recommends adaptation strategies such as blue–green spaces, indoor passive cooling, infrastructural adjustments, heat action plans, etc. However, such adaptation measures require a holistic amalgamation of different stakeholders to fabricate heatwave-resilient cities.

Full textAbstract:
Background Biodegradable PCL- b-PTMC- b-PCL triblock copolymers based on trimethylene carbonate (TMC) and ε-caprolactone (CL) were prepared and used in the 3D printing of tissue engineering scaffolds. Triblock copolymers of various molecular weights containing equal amounts of TMC and CL were prepared. These block copolymers combine the low glass transition temperature of amorphous PTMC (approximately -20°C) and the semi-crystallinity of PCL (glass transition approximately -60°C and melting temperature approximately 60°C). Methods PCL- b-PTMC- b-PCL triblock copolymers were synthesized by sequential ring opening polymerization (ROP) of TMC and ε-CL. From these materials, films were prepared by solvent casting and porous structures were prepared by extrusion-based 3D printing. Results Films prepared from a polymer with a relatively high molecular weight of 62 kg/mol had a melting temperature of 58°C and showed tough and resilient behavior, with values of the elastic modulus, tensile strength and elongation at break of approximately 120 MPa, 16 MPa and 620%, respectively. Porous structures were prepared by 3D printing. Ethylene carbonate was used as a crystalizable and water-extractable solvent to prepare structures with microporous strands. Solutions, containing 25 wt% of the triblock copolymer, were extruded at 50°C then cooled at different temperatures. Slow cooling at room temperature resulted in pores with widths of 18 ± 6 μm and lengths of 221 ± 77 μm, rapid cooling with dry ice resulted in pores with widths of 13 ± 3 μm and lengths of 58 ± 12 μm. These PCL- b-PTMC- b-PCL triblock copolymers processed into porous structures at relatively low temperatures may find wide application as designed degradable tissue engineering scaffolds. Conclusions In this preliminary study we prepared biodegradable triblock copolymers based on 1,3-trimethylene carbonate and ε-caprolactone and assessed their physical characteristics. Furthermore, we evaluated their potential as melt-processable thermoplastic elastomeric biomaterials in 3D printing of tissue engineering scaffolds.

Full textAbstract:
Urban green infrastructure (UGI) and nature-based solutions (NBS) are increasingly recognized as strategies to address urban sustainability challenges. These solutions are attracting key scientific and marketing attention thanks to their capability to improve indoor and outdoor thermal comfort and environmental quality of spaces. In urban areas, where most of the population worldwide lives, indoor-outdoor environmental quality is compromised by local and temporary overheating phenomena, air pollution concentration, and impervious surfaces minimizing urban space resilience to climate change related hazards. In this view, the proposed study concerns the analysis of a greenery system for enhancing outdoor thermal conditions and local warming mitigation for pedestrians for the continental Mediterranean climate. The system has the purpose of designing an outdoor “alive” shading system to be applied in open public spaces, with producing physical and societal benefits. The experimental results showed that the implementation of the greenery, characterized by lower surface temperatures and evapotranspiration compared to a simple pergola system, allows the reduction of outdoor air temperature under the shading system and, thus, higher relative humidity in summer. Specifically, the hygrothermal cooling and the additional shading thanks to the presence of greenery provide local air temperature reduction up to 5 °C at pedestrian level.

Abstract Heat stress negatively affects a variety of production parameters in the swine industry including growth, carcass composition, and reproduction. The combination of climate forecasts and improved genetic performance, indicate increasingly negative impacts of heat stress for the future. Therefore, future heat stress mitigation approaches will need engineered solutions that also consider expected economic risk and corresponding uncertainty. Physically modifying the environment is currently the best approach by utilizing the heat dissipation (albeit, poor) mechanisms of the pig, that is, via the 4 modes of heat transfer, conduction, convection, radiation, and evaporation. A temperature gradient for sensible or vapor pressure gradient for latent heat loss are needed to drive heat exchange. Strategies can then be grouped into (a) modifying the thermodynamic properties of the incoming air via the ventilation system; (b) building characteristics or features; (c) animal zone environment modification; and (d) changes in management. Examples of each strategy include (a) evaporative cooling pads, earth-air-heat exchanger; (b) insulation, spatial orientation; (c) fogging, cooling the drinking water, increasing air velocity; and (d) stocking density. Engineering of future controlled swine environments will need enhanced modeling of heat transfer between pigs and their environment, advanced design/analysis methods of environmental control, and creation of innovative technology that improves sensing, controlling, and modifying the environment. Much of the engineering process starts with and relies on established standards that describe key analytical methods for design, data to enable design computations, and criteria/goals for different environments. There is and will continue to be a need for consistent updates to these data to ensure modern intensive housing is able to provide the proper thermoneutral zone, ventilation rates, etc. for prolific pigs in a changing climate.

Full textAbstract:
In Saudi Arabia, the carbon footprint and energy use that results from using concrete in construction is a major negative contributor to the environmental effects of building materials. Likewise, the impact of annual cooling and heating energy demands has an equally prominent role to play. These demands need to be assessed and benchmarked in order that reduction targets can be set. Saudi Arabia presents its own unique context and local conditions, which creates a challenge when utilizing generic frameworks for assessing the environmental impact of domestic buildings. In meeting this aim, this paper presents a resilience and environmental sustainability assessment framework (RESAF) developed specifically for domestic buildings in Saudi Arabia. RESAF helps designers/builders to minimize the carbon footprint of the building fabric and reduce in-use energy demands of domestic buildings in Saudi Arabia. This paper shows how this framework can be used to reduce, by approximately 23%, the carbon impact from construction materials, primarily by substituting a portion of cement for pulverized fly ash (PFA) or ground granulated blast furnace slag (GGBS). A reduction of 19% in annual cooling and heating energy demand were additionally achieved throughout the building’s life, simply by increasing insulation and using triple-glazed windows. The importance of passing these alternative solutions through the resilience filter is highlighted, not least questioning whether they are really fit-for-purpose.

Full textAbstract:
A growing body of literature recognises the importance of nature-based solutions in providing resilience to the effects of climate change by mitigating urban heat islands. However, a knowledge gap exists regarding the contribution of blue spaces to the urban environment. Recent evidence suggests that blue spaces within urban canyons can promote pollutant removal via the vertical transport of air under certain conditions, but this is inconclusive. Using a numerical solver that accounts for evaporation effects, we investigate the influence of blue space size and shape on the in-canyon flow structure, temperature and water vapour distribution. Simulations were performed for water bodies of varying size and shape at different temperatures compared to the surrounding air. Results suggest that inadequately sized warmer water bodies are unable to promote sufficient vertical transport for pollutant removal, leading to overturning and increased temperature and humidity levels at the pedestrian level, thereby worsening environmental conditions and increasing the risk of heat-related illness and mortality. Hence, larger water bodies are better suited to nocturnal transport of pollutants and accumulated warm air away from the urban surface, while smaller water bodies are better suited to providing localised evaporative cooling. Lastly, irregular water bodies may have a greater cooling effect across a larger area.

Buildings globally are subjected to climate change and heatwaves, causing a risk of overheating and increasing energy use for cooling. Low- energy cooling solutions such as night cooling are promising to realize energy reduction and climate goals. Apart from energy performances, resilience is gaining importance in assessing the performance of the building and its systems. Resilience is defined as “an ability to withstand disruptions caused by extreme weather events, man-made disasters, power failure, change in use and atypical conditions; and to maintain capacity to adapt, learn and transform.” However, there is a clear lack of Resilience indicators specific for low energy cooling technologies. In this paper, the resilience of the night cooling in a residential building in Belgium is assessed for two external events: heat wave and shading failure. This paper shows the first attempt of a resilience indicator for night cooling as the effect on the shock of solar shading failure, heat wave or combination of both. It take 3.4 days to bring down the temperature below 25?, in case of shading failure and heatwaves compared to 9 hours in the reference case. Further research is needed to determine resilience indicators as a performance criteria of low-energy cooling systems.

AbstractHealthy urban ecosystems are increasingly recognised as important for resilient cities and need to be considered as part of GPR. Urban nature-based solutions (NBS) comprising green (vegetation) and blue (water) infrastructure need to be considered at multiple scales from the bioregions, through to catchments, neighbourhoods/precincts, blocks, streets, and buildings, including linkages through and in GPR areas. This chapter describes how climate change—particularly extreme urban heat—is expected to affect Australian cities, and how green and blue infrastructure can help GPR to be incorporated into urban adaptation and mitigation solutions. Topics covered include water-sensitive urban design, nature-based solutions, and urban cooling. The chapter outlines how nature-based solutions can be incorporated into higher-density regenerative urban redevelopment through new technologies and supported by planning models, many of which can be best designed and managed at precinct scale. The ‘additionality’ of green and blue nature-based solutions can offer residents of GPR areas increased liveability and enhanced resilience in both normal and extreme weather.

Abstract The challenges during the aftermath of natural disasters in remote locations, such as unreliable power supply from the grid during crucial times, coupled with ever-increasing energy needs, demand new and innovative solutions to limited energy production. Local, on-site power generation, such as combined cooling, heating, and power (CCHP) systems, may safeguard against grid fluctuations, outages, and provide additional security through grid independence. CCHP systems can provide more reliable and resilient energy supply to buildings and communities while also providing energy-efficient, cost-effective, and environmentally sustainable solutions compared to centralized power systems. Biomass-driven CCHP systems have been recognized as a potential technology to bring increased efficiency of fuel utilization and environmentally sustainable solutions. Biomass as an energy source is created through agricultural and forestry by-products and may thus be efficiently and conveniently transported to remote rural communities. This paper presents a design and implementation analysis of biomass (primarily wood pellets)-driven CCHP systems for a rural community across the United States. The U.S. Department of Energy Climate Regions map was used to determine areas of interest. For this study, all three climates moist, dry, and marine as well as all major climate zones (2–6) were included. To effectively compare small towns across the U.S., the selection process was based on certain criteria: A population of approximately 1,500 people, the existence of a rural hospital, two kinds of schools (E.g., an elementary and a high school), and small businesses. The following places meet those conditions and are located in differentiating climate zones: (2A) Keystone Heights, FL, (3A) Ackerman, MS, (3B) Quincy, CA, (3C) Mariposa, CA, (4A) Hardinsburg, KY, (4C) Coupeville, WA, (5A) Alma, NE, (5B) Lovelock, NV, (6A) Colebrook, NH, (6B) Choteau, MT. Each location was investigated based on the merits of on-site CCHP systems and potential grid independence. The viability of wood pellets (WP) as a suitable fuel source is explored by comparing it to a conventional natural gas-driven and grid-connected system. To measure viability, three performance parameters — operational cost (OC), primary energy consumption (PEC), and carbon dioxide emission (CDE) — are considered in the analysis. The results demonstrate that in many climate regions wood pellet-fueled CCHP systems create significant economic and environmental advantages over traditional systems. Additionally, on-site energy production and the potential for grid independence, especially in the aftermath of natural disasters provide critical services and added upsides of traditional systems. The main factors in increasing the viability of CCHP systems are the appropriate sizing and operational strategies of the system and the purchase price of biomass with respect to the price of traditional fuels.

Abstract A family of “flow-through” turboexpander-generators (TEGs) has been developed by Calnetix Technologies for hydrogen and natural gas pressure letdown applications. A flow-through TEG includes an axial expansion turbine and can be installed directly between two flanges of an existing pipeline. TEGs can be used to generate power throughout the hydrogen and natural gas transmission infrastructure using existing pressure differentials wherever a Joule-Thomson valve is located. These can be upstream, at terminal stations, and downstream, at governor stations. The expander drives a synchronous permanent magnet high-speed generator supported by active magnetic bearings. This paper describes the innovative axial flow-through system architecture, including the use of process gas for cooling the generator rotor and stator. The primary focus of the paper is the economic analysis of the application. Various TEG subsystem design choices and their impact on cost are discussed, including the generator, bearing, expander wheel, seal, and touchdown bearing resilient mount designs. A payback analysis shows that the natural gas TEG has a payback of 2.1 years when a heat exchanger is required for preheating the gas and 1.9 years when waste heat can be used. The hydrogen TEG has a payback of 2.0 years, and does not require external preheating. Finally, a comparison of this technology with other clean energy solutions is presented, using the Levelized Cost of Electricity (LCOE) formulation. The analysis confirms that the LCOE of the expander-generator ($0.40 per megawatt-hour) compares favorably with other types of conventional and renewable energy technologies on a cost basis.

Full textAbstract:
<p>The current study presents a retrofit system, which can be used for strengthening of steel bridge beams using (un-bonded) mechanically-anchored iron-based shape memory alloy (Fe-SMA, ‘memory-steel’) strips. After anchoring, the Fe-SMA strips are activated by a heating and a subsequent cooling process. The anchorage system can simultaneously hold two strips (each with 50-mm width and 1.5-mm thickness) and transfer their prestressing force to the steel beam at the strip ends. The system is based on friction and does not introduce any damage to the parent metallic substrate. Owing to the so-called ‘shape memory effect’ (SME) of the alloy, the strips are prestressed after activation by heating up to a defined maximum temperature. After strengthening, the beam was statically loaded up to 60% of its yield capacity. Finally, in order to examine efficiency of the proposed SMA-strengthening solution, the steel beam was subjected to cyclic loading. The results of the static tests demonstrated the positive effects of the prestressed Fe-SMA strips on reducing tensile stresses in the beam bottom flange. Furthermore, the evolution of the prestress level in the strips during the fatigue loading was studied. The presented experimental study on the strengthened steel beam shows the effectiveness of un-bonded Fe- SMA strips as a retrofitting technique to enhance the static and fatigue performance of metallic bridge girders.</p>

Full textAbstract:
High power, high efficiency propulsion equipment with a high shock resilience capability that occupies the minimum volume, with a low weight and a very low noise signature is a “holy grail” of naval propulsion. Significant steps towards this goal have been made in the area of naval electric propulsion in the last 30 years, but it is hard to combine all these features in a single design since some features tend to militate against others. Solutions, therefore, require a balance between the thermal challenges of high power in a low volume and the requirement for shock proof, low signature machines. A permanent magnet propulsion motor with a patented novel cooling system designed for power density and low structureborne noise is being developed, manufactured and tested as a technology demonstrator. It is part of a programme part funded by InnovateUK under the Optimised Electric System Architecture project in partnership with the University of Nottingham and the University of Warwick. The primary market for the motor is envisaged to be naval and marine research vessels where power density and low noise is important. The motor is low speed and designed for direct mechanical coupling in the shaft line to the propeller and will be suitable for full electric or hybrid propulsion since the design is inherently scalable from relatively low powers up to those required for full electric warship propulsion. This paper describes the principles of the design and the approaches used to achieve the combination of high power density, high efficiency, high torque and low noise. It describes the thermal management approach and how the thermal behaviour of the different elements of the motor have been modelled. It also shows how advanced modelling techniques, combined with laboratory based and simple, practical testing have been used to develop the design and the manufacturing techniques required by this innovative solution. The paper also describes the testing approach used to validate the machine and its integration into a wider Direct Current or Alternating Current distribution system that could include energy storage elements. Finally, the performance of the motor is discussed along with the probable next stages in its development.
