Gold mineralisation is spatially and chronologically correlated with fault/shear zones in many of the world-class gold mines. Hence, the indirect exploration for Au mineralisation is linked with shearing and complex structures in many areas. Hence, in general, the need for a rapid, effective and new technology for gold exploration that reflects the structure set-up, shear zones, faults and related structural elements is crucial in the gold industry. In this article, we present an example of an integrated approach to gold exploration in the Fawakheir-Attala gold mining prospect in the eastern desert of Egypt. Remote sensing is used to test for rock differentiation; intensive field geological investigations were conducted along several traverses. Petrographic and geochemical analysis of selected samples confirmed Au content in some localities. Moreover, magnetic methods are used extensively (either aeromagnetic or measured land profiles) to investigate the magnetic signature of the different reported rock units and their relationship with gold occurrences and deposits. Normalised source strength transformation, magnitude magnetic transforms and subsurface modelling are used to explore the inherent relation between the surface and subsurface magnetic susceptibilities. The magnetic signature of the talc-carbonate rocks is determined. The gradational contact against the serpentinite is explained. Because three current Au mines are associated with contacts/fractures, the clear relation between the contacts/fractures and the magnetic data and the comparison with the contact occurrence density COD (heat) magnetic filtered map, the present analysis workflow can now be used to suggest new locations for Au occurrences.

Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries.The effects of climate change need urgent action. Most countries and organizations have made commitments to reduce carbon. Healthcare, and especially surgery, is responsible for producing a large amount of carbon and for other behaviours that are harmful to the environment. The aim of this study was to identify the most practical and safe interventions to make surgery more environmentally friendly. Interventions to achieve green surgery were found in the literature and added to a list. The list was ordered and shortened, following advice of doctors and patients. The safest and most practical interventions were at the top. The top three areas for change were to reduce the use of one-use items and energy, recycle, and manage waste appropriately. There are several ways that we can make surgery greener. The list produced gives us practical examples of what can be done.

Objectives: To compare the remineralization potential of Curodont Repair Fluoride Plus Versus CPP -ACP in management of white spot lesions.
Methodology: 48 white spot lesions in patients received randomly two types of remineralizing agents, either Curodont Repair Flouride Plus (self-assembling peptide p11-4) or MI paste daily use, both materials were applied according to the manufacturer’s instructions. White spot lesions were evaluated before and after 1, 4, and 6 months follow up periods by assessors to assess remineralization potential using ICDAS II Criteria and digital photographs using analysis software to get the percentage of white spot lesions. Results: According to ICDAS II, intergroup comparison between both materials have shown no statistically significant difference, Intragroup comparisons within Curodont Repair Fluoride Plus have shown statistically significant difference between different follow-up periods (P < 0.0001). Curodont Repair Fluoride Plus had 25% less risk for (ICDAS 1and 2) than CPP-ACP after 6 months (RR= 0.75, 95% CI, P=0.2498). According to the photographic analysis, Two-way ANOVA revealed statistically significant effect of material and follow-up on WSL % (P<0.001). Conclusions: Curodont Repair Flouride Plus is a biomimetic remineralizing agent that provides a therapeutic option for enamel regeneration. Curodont repair fluoride plus provided a better chance for complete healing of incipient lesions.
