Abstract:
In large-sized metal structures, various stress concentrators are often present, which affects the operation of the material. These are intermittent bonds, holes, welded joints, material defects, etc. As a result of overloads under the action of an external cyclic load on structures in the area of stress raisers, the cycle asymmetry, the level of maximum stresses and deformations increase. In this case, the determination of the limit values of the stress cycles can be performed using a diagram of the limit stress amplitudes.

Abstract:
An ejector refrigeration system is a promising heat-driven refrigeration technology for energy consumption. The ideal cycle of an ejector refrigeration cycle (ERC) is a compound cycle with an inverse Carnot cycle driven by a Carnot cycle. The coefficient of performance (COP) of this ideal cycle represents the theoretical upper bound of ERC, and it does not contain any information about the properties of working fluids, which is a key cause of the large energy efficiency gap between the actual cycle and the ideal cycle. In this paper, the limiting COP and thermodynamics perfection of subcritica

Abstract:
The thermally activated dynamics of an uniaxial superparamagnetic particle are studied here from the point of view of approach towards a steady state minor hysteresis loop representing a limiting cycle. The particle is initially at an arbitrary state, and is driven by a sufficiently small external applied ac magnetic field till the limiting minor hysteresis loop is reached with a desired precision. The number of periods required to reach the limiting cycle is found to satisfy an Arrhenius-type law, with an exponential dependence on the inverse ambient temperature. We tentatively associate this

Abstract In many supercritical CO2 cycle implementations, compressor or pump inlet conditions are relatively near the two-phase region. Fluid acceleration near the compressor inlet can result in the potential for condensation or cavitation at the inlet. Despite potential mitigating effects or evidence in the literature, potential two-phase operation is a high-risk condition and may not be recommended for high-reliability system design. This paper presents a summary of the existing literature documenting inlet phase change in sCO2, and presents an analysis of required conditions to avoid phase

Abstract:
Supercritical carbon dioxide (S-CO2) Brayton cycle represents significant advantages in solar tower application. Various configurations of S-CO2 Brayton cycle employing recuperation, recompression, intercooling and reheating have been investigated. The thermodynamic performance of each cycle configuration is optimized by using Genetic Algorithm in which the maximum cycle efficiency is defined as the objective function. The optimization process is comprehensive, i.e., the decision variables such as temperature and pressure of turbines, compressors, re-heaters, inter-coolers, and the pinch point

Abstract:
Enabling child protection by building comprehensive, context-specific tools to capture child domestic worker environments. Child domestic work can deprive children of their right to education, expose them to physical and emotional abuse, and stunt their physical and cognitive development. Moreover, engaging in domestic work at a young age can perpetuate a cycle of poverty, denying children the opportunity to break free from socioeconomic constraints and limiting their potential for a better future.

Abstract:
This work examined previously developed injection mold inserts with reduced thermal mass, with regard to lightweight construction approaches. These were optimised for oil-variothermal temperature control using simulative support. Additive manufacturing (AM), with its high degree of freedom in design, enables the implementation of individual, conformal cooling channels and can additionally support the efficiency of the variothermal process. The thermal mass of the injection mold is often a limiting factor in terms of process efficiency, which is also addressed in the analysis and optimisation c

Abstract:
The world is not currently on course to limit global warming to 1.5 degrees Celsius. Carbon dioxide emissions are increasing, emissions targets in countries’ Nationally Determined Contributions are not ambitious enough, and oil and natural gas production are expected to increase given current policies. A lack of investment in the low-carbon economic transition partly explains this limited progress towards the Paris Agreement’s goals. Market imperfections explain this underinvestment in the low-carbon economic transition. Climate change is a tragedy of the horizons, as many of the costs of clim

Full text
Abstract:
Aspergillus terreus was reported as the promising fungal strain for itaconic acid; however, the commercial production suffers from the low yield. Low production yield was claimed as the result of completing TCA cycle towards biomass synthesis while under limiting phosphate and nitrogen, TCA cycle was somewhat shunted and consequently the metabolite fluxes move towards itaconic acid production route. By regulating enzymes in TCA cycle, it is believed that itaconic acid production can be improved. One of the key responsible enzymes involved in itaconic acid production was triggered in this study

The 6 th Assessment Report cycle of the Intergovernmental Panel on Climate Change (AR6) comes at a precipitous moment in history. Human influence has warmed the planet, and widespread and rapid impacts are occurring to natural and human systems in all regions of the world. In response, immediate action is needed if there is to be any hope of limiting global warming to 1.5°C or well below 2°C below pre-industrial levels, as well as preparing for and adapting to current and future risks. The transformations needed in response to climate change will require decisive action in cities and urban are

Objectives: to demonstrate nitrogen fixation in the gut of Ceratitiscapitata, the Mediterranean fruit fly and that fixed nitrogen is important for the fly. Background: Fruit flies (Diptera: Tephritidae) are a highly successful, widespread group of insects causing enormous economic damage in agriculture. They are anautogenous, i.e. the acquisition of nitrogenous compounds by both male and female is essential for the realization of their reproductive potential. Nitrogen, although abundant in the atmosphere, is paradoxically a limiting resource for multicellular organisms. In the Animalia, biolog

Abstract:
For robust pavement design, accurate damage computation is essential, especially for loading scenarios such as truck platoons. Studies have developed a framework to compute pavement distresses as function of lateral position, spacing, and market-penetration level of truck platoons. The established framework uses a robust 3D pavement model, along with the AASHTOWare Mechanistic–Empirical Pavement Design Guidelines (MEPDG) transfer functions to compute pavement distresses. However, transfer functions include high variability and lack physical significance. Therefore, as an improvement to effecti

Abstract:
Acceptance of climate change as a Left-leaning political agenda is limiting support for climate action. New research across the G20 and beyond shows a large, untapped base of support on the political Right. We don’t see it because we don’t speak to it, so the support stays latent. If we learn to connect with this group, we can turn this vicious circle into a virtuous one, extend the support for climate policies from a minority to a majority, and achieve the cross-party consensus that can sustain climate commitments over multiple election cycles.

Abstract:
arbon dioxide (CO₂) has a negative impact on the climate, but it also has several practical areas of use. Many industrial processes emit CO₂ in high concentrations, which could be captured to mitigate emissions while also creating valuable products. One example of such a process is biogas upgrading – a process separating renewable gases, where methane is taken care of for use as vehicle fuel or industrial energy carrier, while CO₂ is released into the atmosphere. The aim of this project has been to chart alternatives and technologies for taking care of green CO₂ from biogas upgrading, so-calle
