“…The velocity distribution in itself is of great postdiscovery interest. While the Gaussian distribution of the Standard Halo Model is monolithic, the real velocity distribution will likely possess complexity and substructure acquired over the Milky Way's tumultuous 13-Gyr lifetime (60,(64)(65)(66). Such substructure has already been revealed in the dark halo's stellar counterpart (67)(68)(69)(70) by the revolutionary data set from the Gaia mission (71).…”

Searches for dark matter–induced recoils have made impressive advances in the last few years. Yet the field is confronted by several outstanding problems. First, the inevitable background of solar neutrinos will soon inhibit the conclusive identification of many dark matter models. Second, and more fundamentally, current experiments have no practical way of confirming a detected signal's Galactic origin. The concept of directional detection addresses both of these issues while offering opportunities to study novel dark matter– and neutrino-related physics. The concept remains experimentally challenging, but gas time projection chambers are an increasingly attractive option and, when properly configured, would allow directional measurements of both nuclear and electron recoils. In this review, we reassess the required detector performance and survey relevant technologies. Fortuitously, the highly segmented detectors required to achieve good directionality also enable several fundamental and applied physics measurements. We comment on near-term challenges and how the field could be advanced. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 71 is September 2021.

“…Thus, aerogel insulation achieved a faster reduction in carbon emissions than other insulators. Necib, H and Necib, B (2020) utilized analytical approaches to computing the optimal insulation thickness using a FORTRAN programmed. According to the findings, the best insulation thickness for the four East, North, West, and South orientations are 7.3, 6.2, 7.3, and 6.7 cm, respectively.…”

The insulation of a building's envelope is critical for reducing energy consumption, enhancing indoor thermal comfort, and achieving sustainable development goals. This theoretical work focused on the energy and thermal aspect of insulators and glazing to determine the optimal thermal insulation and the best glazing for the building envelope in the Mediterranean region where the province of Ain Temouchent, Algeria, was taken in this study. This study evaluated the effectiveness of insulation materials, which are expanded polystyrene, glass wool, rock wool, and wood fiber of varying thicknesses, and glazing in the Algerian market. The TRNSYS 17 software is used to simulate the building's behavior. The study finds that wood fiber insulation with a 9 cm thickness provides the best thermal performance, resulting in a 26% reduction in energy costs compared to 3cm of expanded polystyrene. Furthermore, upgrading from single to double glazing can reduce heating and cooling costs by 23% and 10%, respectively, demonstrating the importance of proper insulation and glazing in achieving energy efficiency, and enhancing indoor thermal comfort for occupants. In conclusion, this study provides valuable findings for designing energy-efficient buildings with optimal thermal insulation and glazing. Future research should explore broader factors affecting building performance, such as the long-term performance and durability of materials in varying climates and building designs, as well as the impact of occupancy and building orientation. Although the study acknowledges its limited examination of factors and options, it still provides valuable insights into building performance with insulation and glazing.

“…The aggressive climatic change of the earth noticed during the summer of the year 2021 must force us to take severe and rapid decisions to reduce the terrestrial pollution, and this by the reduction of the consumption of energy as well as the transition to clean and renewable energies. Several studies have proposed solutions to reduce energy consumption, such as the installation of an optimal insulation thickness on the building envelope [1][2][3], the use of vegetation [4][5][6], the introduction of passive heating/cooling systems in buildings [7][8][9], the use of phase change materials (PCM) for energy storage [10][11][12], the introduction of smart energy technologies or proposing architectures that save energy [13,14].…”

This study aims to improve the thermal efficiency of concrete slabs by introducing a plant material. This can contribute to the improvement of internal thermal comfort for buildings and this by lower energy consumption. For this, several experiments were carried out at the laboratory, to find the thermal properties of a new innovative building material produced by inserting ALFA (STIPA TENACISSIMA) into a concrete slab. Several mass percentages of ALFA relative to the total mass of the concrete slab (0%, 0.4%, 0.8%, 1.2% and 1.6%) were studied to see the effect of the introduced quantity of this plant on the thermal conductivity of concrete. It was concluded that the insertion of ALFA in the concrete, decreases considerably the thermal conductivity. The best results are noticed for 1.2% of ALFA, whose thermal conductivity of the concrete is reduced up to 50.61%. As a result, heat gains and losses, through wall or slab, are significantly reduced, which reduces the energy consumed by cooling and heating of homes. In addition, the degree-day method was used to calculate the costs of cooling and heating energy for 58 regions in Algeria. The lowest total energy cost is noticed in the TENES region, while the highest energy cost is noticed in the BORDJ B. MOKHTAR region.
