Cement producers and their investors are navigating evolving risks and opportunities as the sector's climate and sustainability implications become more prominent. While many companies now disclose greenhouse gas emissions, the majority from carbon-intensive industries appear to delegate emissions to less efficient suppliers. Recognizing this, we underscore the necessity for a globally consolidated asset-level dataset, which acknowledges production inputs provenance. Our approach not only consolidates data from established sources like development banks and governments but innovatively integrates the age of plants and the sourcing patterns of raw materials as two foundational variables of the asset-level data. These variables are instrumental in modeling cement production utilization rates, which in turn, critically influence a company's greenhouse emissions. Our method successfully combines geospatial computer vision and Large Language Modelling techniques to ensure a comprehensive and holistic understanding of global cement production dynamics.

Background: Prone lateral spinal surgery for simultaneous lateral and posterior approaches has recently been proposed to facilitate surgical room efficiency. The purpose of this study is to evaluate the feasibility and outcomes of minimally invasive prone lateral spinal surgery using a rotatable radiolucent Jackson table.
Methods: From July 2021 to June 2023, a consecutive series of patients who received minimally invasive prone lateral spinal surgery for various etiologies by the same surgical team were reviewed.

The synergistic utilization of multiple solid waste is an effective means of achieving green filling and resource utilization of solid waste in mines. In this paper, the synergistic effects of solid waste granulated blast furnace slag (GS) and carbide slag (CS) as cementitious materials (GCCM) are investigated, along with their preliminary feasibility in combination with coal gangue (CG) and furnace bottom slag (FBS) for the preparation of backfill materials. The synergistic hydration mechanism, mechanical properties, working performance of GCCM and GBC were studied, and the environmental impact and cost-effectiveness of GBC were evaluated.

Nowadays, Egypt is treating the Nile River Water to produce drinking water, and this process generates large amounts of waste, around 635 million m annually, which is called water treatment plant sludge (WTPS). This WTPS cost the government around 30 million US dollars to return it back to the Nile River in addition to negatively affecting the environment. Therefore, there is an urgent need to find environmentally friendly alternatives that reduce the impact of such an issue.

Analyzing the chemical composition of different kinds of acrylic cement is necessary to understand their properties and suitability for curing bone defects. Conducting various chemical tests can give valuable insight into the composition, viscosity, and performance characteristics of each kind of cement, Therefore, our study aimed to find safety standards and the effectiveness of these products for medical applications. The polymeric characterization was determined by Nuclear Magnetic Resonance (H-NMR) spectroscopy and Fourier-transform infrared spectroscopy (FTIR).

Background: Crown cementation is a common technique for implant-supported prosthodontics. However, for possible slipping of the cement below the mucosal margin, its thorough removal poses some issues. The objective of this study was to evaluate the presence of submucosal cement residues in patients with peri-implant disease by endoscopic visualization and to investigate the potential correlation between the pathological scenario and the spatial position of cement residues.
