ABSTRACT The feasibility of unmanned-aerial-vehicle-based photogrammetry was assessed for the reconstruction of high-resolution topography and geomorphic features of quarries by nadir and off-nadir imagery. The test site was a quarry located in the rural area of Turi (Bari, southern Italy). Two processing scenarios were …
1. Introduction. Concrete is a sustainable and versatile construction material which can produce structures that last for thousands of years. Due to the many areas of application, concrete is the second most consumed material on Earth, only after water, with a global production of around 4.1 billion tons of cement in 2021 (Statista, 2023), and an …
Strategic Goals, Intermediate Goals and Activity Goals Strategic Goal 1: Reduce mine workers' risk of occupational illnesses.

Pathways to combination strategy: Grow, stabilize, retrench; Grow, retrench, stabilize; Stabilise, retrench, grow; Retrench, stabilize, grow. Even among the broad strategies, an organization may choose many different options. Combination most often depends on how an organization perceives its balanced portfolio.
consisting of 30% waste plastic, 25% y ash, and 45% quarry dust was identied as highest compressive strength compared to the conventional one. Furthermore, a comprehensive probabilistic analysis was conducted, revealing that the most suitable probabilistic model aligns with the normal distribution.

Within concrete engineering, the uptake of self-compacting concrete (SCC) represents a notable trend, delivering improved workability and placement efficiency. However, challenges persist, notably ...
The majority of the wet digestion methods, followed in geochemical analysis, use acids such as HCl, HNO 3, HClO 4, H 2 SO 4 and HF, or a combination of them. The use of HF becomes inevitable in most sample decompositions because of its ability to dissolve silica and other silicates by the following reaction: SiO 2 + 6HF → H 2 SiF 6 + …

Therefore, most mAbs in this analysis (67%; 28 of 42) went through some degree of manufacturing changes during development; and for half …
Definition. Strategic management process is a method by which managers conceive of and implement a strategy that can lead to a sustainable competitive advantage. [1]. Strategic planning process is a systematic or emerged way of performing strategic planning in the organization through initial assessment, thorough analysis, strategy …
Rock slope geometry and discontinuity properties are among the most important factors in realistic rock slope analysis yet they are often oversimplified in numerical simulations. This is primarily due to the difficulties in obtaining accurate structural and geometrical data as well as the stochastic representation of discontinuities. Recent …
Quarry planning encompasses a comprehensive analysis of geological, environmental, and market factors to optimise resource utilisation and ensure sustainable development. In the UK, quarry planning must align with statutory requirements outlined by planning authorities and environmental agencies.
The combination of quarry restoration strategies in semiarid climate induces different responses in biochemical and microbiological soil properties ... A precondition for ecosystem reclamation in such highly disturbed areas is the development of functional soils with sufficient amount of organic matter. ... Analysis of phospholipid …
The 120-year-old basalt quarry has been the subject of numerous assessments in recent years, including one by KPMG in 2019, to investigate possible development options. Committee chair Councillor Carol Taylor said the two strategies elected from the Rehabilitation Strategy Report were numbers one and four.
A rational screening strategy for pharmaceutically important peptides has been developed that uses combinations of reversed‑phase ultrahigh-pressure liquid chromatography (UHPLC) columns and mobile phases that exhibit complementary reversed-phase chromatographic selectivity using either UV- or mass spectrometry (MS) …
We defined the approximate limits of the quarry complex, located the in situ geological source of the fine-grained basalt used for adze manufacture, report the petrographic and geochemical variability of the source rock, …
