Abstract:
In this paper, we present a complete work on steady state spherically symmetric Bondi type accretion flow in the presence of cosmological constant (Λ) in both Schwarzschild-de Sitter (SDS) and Schwarzschild anti-de Sitter (SADS) backgrounds considering an isolated supermassive black hole (SMBH), with the inclusion of a simple radiative transfer scheme, in the pseudo-general relativistic paradigm. We do an extensive analysis on the transonic behavior of the Bondi type accretion flow onto the cosmological BHs including a complete analysis of the global parameter space and the stability of flow,

Abstract:
Abstract We present an exact γ = 5/3 spherical accretion solution that modifies the Bondi boundary condition of ρ → constant as r → ∞ to ρ → 0 as r → ∞. This change allows for simple power-law solutions on the density and infall velocity fields, ranging from a cold empty freefall condition where pressure tends to zero, to a hot hydrostatic equilibrium limit with no infall velocity. As in the case of the Bondi solution, a maximum accretion rate appears. As in the γ = 5/3 case of the Bondi solution, no sonic radius appears, this time however, because the flow is always characterized by a constan

ABSTRACT The classic Bondi solution remains a common starting point both for studying black hole growth across cosmic time in cosmological simulations and for smaller scale simulations of active galactic nuclei (AGN) feedback. In nature, however, there will be inhomogeneous distributions of rotational velocity and density along the outer radius (Ro) marking the sphere of influence of a black hole. While there have been many studies of how the Bondi solution changes with a prescribed angular momentum boundary condition, they have all assumed a constant density at Ro. In this Letter, we show tha

We consider a characteristic initial value problem, with initial data given on a future null cone, for the Einstein (massless) scalar field system with a positive cosmological constant, in Bondi coordinates.

We study fluid distributions endowed with hyperbolic symmetry, which share many common features with Lemaitre–Tolman–Bondi (LTB) solutions (e.g., they are geodesic, shearing, and nonconformally flat, and the energy density is inhomogeneous). As such, they may be considered as hyperbolic symmetric versions of LTB, with spherical symmetry replaced by hyperbolic symmetry. We start by considering pure dust models, and afterwards, we extend our analysis to dissipative models with anisotropic pressure. In the former case, the complexity factor is necessarily nonvanishing, whereas in the latter cases

ABSTRACT Steady-state, spherically symmetric accretion flows are well understood in terms of the Bondi solution. Spherical symmetry, however, is necessarily an idealized approximation to reality. Here we explore the consequences of deviations away from spherical symmetry, first through a simple analytic model to motivate the physical processes involved, and then through hydrodynamical, numerical simulations of an ideal fluid accreting on to a Newtonian gravitating object. Specifically, we consider axisymmetric, large-scale, small-amplitude deviations in the density field such that the equatori

Adhesion is critical to such a system. Good adhesion is achieved by a rough angular profile on the substrate to allow the polymer to physically grip the substrate.

Abstract:
In 2019, it was estimated that, of 5,000 Nordic start-ups, 10% included solutions that addressed the 17 United Nations Sustainable Development Goals (SDGs). However, many of them struggled to make a profit, especially at the early stages and mostly due to a lack of access to the market and to the right supporters. This publiction consists of two sections: The first part addresses barriers to public procurement, enablers for social innovation, and institutional support measures; In part two, we evaluate how Nordic municipalities use alternative financial models such as social impact bonds (SIBs

Abstract:
Meeting the climate change challenge requires structural transformations in infrastructure, health and social protection, and financial institutions. Climate action calls for a redirection of existing financial flows. An adequate response requires redirecting financial flows to achieve annual spending of 2 to 8 percent of GDP on the provision of infrastructure services and 5 to 11 percent of GDP on social programs. Specific financing sources, such as green taxes and sustainable bonds, can finance part of climate efforts. However, to redirect public and private spending and foreign investment i

Abstract:
Caribbean small island developing states (SIDS) rely heavily on imported fossil fuels, leaving them vulnerable to unpredictable shifts in global fuel prices and supply disruptions. The region possesses abundant renewable energy resources including solar, wind, hydro, tidal and geothermal. However, the transition to renewable energy has been slow. This policy brief proposes solutions to aid Caribbean SIDS in accelerating their transition to renewable energy. Recommendations: • Enhance knowledge and understanding of renewable energy through public education campaigns. • Issue thematic corporate

Abstract:
This report analyzes the new financing schemes for sustainable projects that are being developed in different parts of the world under public-private partnership formulas. The main objective of the report is to identify the key elements of these schemes based on innovative governance and collaboration structures and financing solutions, in order to draw conclusions and present recommendations applicable to the Basque Country. The new financing schemes are analyzed, including the actors involved (from public entities and financial institutions to companies, citizens and third-sector association

Full text
Abstract:
In this paper an isotropic hardening elastoplastic constitutive model for structured soils is applied to the simulation of a standard CPTu test in a saturated soft structured clay. To allow for the extreme deformations experienced by the soil during the penetration process, the model is formulated in a fully geometric non-linear setting, based on: i) the multiplicative decomposition of the deformation gradient into an elastic and a plastic part; and, ii) on the existence of a free energy function to define the elastic behaviour of the soil. The model is equipped with two bonding-related intern

Full text
Abstract:
Concrete overlays have proven to be an effective maintenance treatment as they slow de-icing chemical and water penetration into the original deck surface. Typically, due to vibration, structural flexibility, and weak bond between the concrete overlay and deck concrete potentially due to poor construction, de-bonding develops at the boundary between the original deck and overlay. This de-bonding creates voids, providing reservoir for chloride laden water to fill after it penetrates cracks in the surface. Displacing this liquid solution and filling these cracks with epoxy helps reduce freeze/th

Abstract:
This report outlines the cascading environmental, social, and economic impacts of aquatic biodiversity loss in Southeast Asia and recommends ways to develop scalable projects that tackle river pollution and support sustainable development. Focusing on the Mekong and other major rivers, the report explains the effects of rapid urbanization, climate change, and industrialization on river basin pollution in the region where 110 million people lack access to safe water. It outlines how a combination of financing mechanisms such as blue bonds, nature-based solutions including mangrove reforestation
