Summary: Most rib fractures can be detected within the first week after trauma. Detection of occult rib fractures will be delayed with increase of age, and repeated CT scanning should be appropriately postponed in patients at different ages. Trabecula, inner and outer plates, costal angle, and cartilage are the primary locations for occult and subtle fractures which should be carefully evaluated.

Summary: The wicking dynamics in yarns are not solely determined by inter-fiber pore filling, but are mainly influenced by the transition processes between pores and the structure of the pore network. The yarn pore system consists of a sparse network of long and narrow pores, which leads to step-wise wicking dynamics with fast pore filling events and long waiting times between filling events.

Summary: This recommendation presents a laboratory method to test the durability of natural stone and fired-clay brick units against salt crystallization. The method replicates salt damage caused by capillary transport and evaporation and considers two stages in the test: accumulation and propagation. Two types of salt, sodium chloride and sodium sulphate, were tested separately. The procedure includes visual observations, photography, and measurement of material loss, and has been preliminarily validated in round robin tests.

Summary: This study investigates the porosity and pore structure of 3D printed concrete elements using mercury intrusion porosimetry and X-ray micro-computed tomography. The results show that the interlayer region contains larger and interconnected pores with low tortuosity, which can enhance ion transport. The study compares two different cement systems and finds that the calcium sulfoaluminate-limestone blend has higher pore complexity and tortuosity. X-ray micro-computed tomography is able to characterize both open and closed pores in the printed sample at high resolution. This study provides insights into ion transport and durability performance of printed concrete elements.

Summary: Water repellents are commonly used on the outer surfaces of buildings to make them more hydrophobic. However, there is limited research on their efficiency under practical conditions. This study examines the hydrophobic efficiency of a siloxane-based water repellent on different materials and investigates the effects of material characteristics and application conditions on its performance. The results show that spray-treated samples have comparable hydrophobic efficiency to capillary absorbed samples, and temperature and humidity have little impact on the repellent's efficiency.

Summary: Urbanisation intensifies environmental stressors and limits green spaces, but vertical greening (VG) can mitigate these stressors and enhance well-being in densely built areas. However, heritage buildings are often excluded from VG initiatives due to concerns about potential damage. This study in Antwerp, Belgium investigates the presence of VG on heritage buildings, finding that it is implemented on a significant proportion of buildings in neighbourhoods lacking green space. This reveals the potential for VG on heritage buildings and the need for guidance and integration strategies.

Summary: This study investigates the effects of Re and Ta interactions on the precipitation of the TCP phase in experimental alloys under long-term thermal exposure. The study finds that microstructure segregation is not fully eliminated even with standard heat treatment, and the interaction between Re and Ta enhances the formation of the TCP phase. Thermodynamic calculations and first-principles analysis reveal that Re significantly improves the driving force of TCP phase precipitation. The study also observes a phase transition from the sigma-phase to the P-phase, with Ni playing a crucial role in the diffusion process.

Summary: The microstructures and corrosion resistance of TC11 components were significantly improved using a high-power, high-speed laser metal deposition (LMD) process and subsequent post-heat treatment, with greater improvements observed in the deposition direction. The significant improvement of corrosion resistance in the deposition direction is mainly due to the weakening of the charged galvanic corrosion effect between the non-interlayer zone and interlayer zone.

Summary: In this study, the microstructures and mechanical properties of interphase precipitation strengthening micro-alloyed steels were investigated. The addition of Cr was found to increase the yield strength without significant decrease of ductility. Thermodynamics analysis revealed that the addition of Cr led to grain refinement and decrease of sheet spacing of nanoprecipitates. Calculations showed that the decrease of interphase-precipitated carbides sheet spacing and the refinement of grain size were responsible for the strength enhancement of Cr microalloyed steel.
