Effects of exposure sequence and GGBS cement replacement on performance of concrete subjected to carbonation and chloride ingress
Authors: Blackshaw Grace A. , Forsdyke Jessica C. , Lees Janet M. 
Published: September 2024

AbstractIn a variety of applications, such as in tidal zones, abutments of bridges and concrete tunnel linings, reinforced concrete is exposed to both carbonation and chloride ingress. The exposure can be either simultaneous or sequential. However, durability design rarely considers synergistic effects due to carbonation and chloride ingress, even though this may have detrimental consequences for performance. Comparative implications of exposure sequence across different concrete compositions are also unknown. In this study, an experimental investigation on the effects of the sequence of carbonation and chloride ingress was conducted, using two concretes which differ by 50% cement replacement with ground granulated blast furnace slag (GGBS). Specimens were exposed to a combination of 10% CO2 accelerated carbonation and immersion in 3% sodium chloride solution, in either sequence, and compared with companion samples subjected to only one of these aggressive environments. The extent of carbonation was measured using phenolphthalein indicator solution, while silver nitrate and Rapid Chloride Testing provided indicators of the chloride ingress. For both concrete mixes, specimens with prior chloride ingress exhibited a decreased rate of carbonation when compared to specimens with no prior exposure. Conversely, specimens with prior carbonation displayed an increased rate of chloride ingress compared to non-carbonated counterparts and a step in the acid soluble chloride content in the region of the carbonation front. The concrete composition appeared to play a role since a greater increase in chloride diffusion coefficient due to prior carbonation was observed in the mix with 50% GGBS replacement than the mix without. These findings suggest that in concrete structures exposed to air and saline environments, the effects of sequential exposure should be characterised.
Optimal content of bio-fibers in structural ice

Published: September 2024

AbstractThe use of ice as structural material has two main concerns: the low strength and the brittle failure of the structures. With the aim of finding a solution to these problems, an experimental campaign, performed on fiber-reinforced ice (FRI) samples, made with plain water and bio-fibers, is presented in this paper. In total, 12 ice prisms were cast at − 18 °C with a different content of fibers, and then tested in three-point bending and uniaxial compression. Test results indicate that the presence of a reinforcement increases both flexural and compressive strength with respect to plain ice. Moreover, FRI is a tougher material, as multiple cracking and deflection hardening behavior can be observed in the flexural tests. However, the mechanical performances of plain ice are not always enhanced by the fiber-reinforcement. Therefore, an empirical model, capable of predicting the optimal content of bio-fibers, is also proposed.

“Espanhol para Todos”: uma autoetnografia do entender-se professora decolonial
Authors: Rodrigues Millena Dánily P. , Assis Joziane Ferraz de 
Published: September 2024

Desde 2017, com a revogação da Lei n. 11.161/2005, a Língua Espanhola não compõe mais o currículo da Educação Básica brasileira. Professoras e professores de Espanhol têm encontrado, porém, de forma autônoma, maneiras de ocupar esse espaço. Com base nos estudos de Hall (2006) sobre o conceito de identidades fluidas e em contínuo deslocamento, o presente artigo apresenta uma narrativa autoetnográfica, cujo objetivo é relatar o processo de entender-me uma professora de Espanhol nesse cenário de resistência. A narrativa se refere às experiências da primeira coautora do artigo sob a orientação da segunda coautora. Engajada na luta antirracista e anticolonial, dialogo com as minhas interseccionalidades de raça e de gênero, que tanto influenciam na minha perspectiva sobre o ensino e sobre a professora que eu busco me tornar. Para isso, apresento neste texto a minha experiência de construção de um cursinho popular e gratuito chamado “Espanhol para Todos”, que se tornou um projeto de extensão vinculado ao Instituto Federal do Sudeste de Minas Gerais, em 2021, e que teve como aporte teórico estudiosos da decolonialidade. Ainda na graduação em Letras com habilitação em Língua Portuguesa e Língua Espanhola, encontrei nas abordagens decoloniais um caminho para enfrentar a hegemonia do ensino do Espanhol europeu, ampliando o olhar para a América Latina e promovendo narrativas outras para uma Educação crítica e antirracista por meio da valorização das identidades do Sul.

One-Plate Meals for Remote-Site Workers
Authors: Al Msharrafawee H. T. , O'Keeffe J. 
Published: September 2024

Abstract
A pre-ordered and balanced healthy meal on one plate is offered in the dining facilities or delivered to job sites. Personnel collect meals at the entrance of the mess hall instead of going through the food line, where they could otherwise fill up on less healthy or less nutritious options. One-plate meals provide whole grains, vegetables, protein, and fruit in proper portions and quantities. Vegetarian options are also provided.
The goal of the one-plate meals program is to promote healthier diet options for remote-site workers during long rotations at locations where catering services are provided. Personal behavior is influenced through the elimination of the intention-behavior gap and by introducing small environmental changes. The meal is pre-ordered a day earlier, and it has an attractive presentation using a single plate with one side dish (typically fruit salad). Employees can either eat in or take the meal to go. One-plate meals are presented using dinnerware sets and packaging materials that are distinguished and of a better quality than those used for the regular food line.
One-plate meals offer a convenient and healthy choice for employees who are accommodated on site. It keeps their daily diets free from the less healthy choices that can be selected as they walk through the entire food line because these are often hard-to-resist less healthy picks that can easily fill a plate. The program also offers a time-saving option for employees on a tight schedule who don't have time to wait in line.
Over time, influencing the dietary behavior of employees and encouraging them to adopt healthy nutritional choices at work could extend to the choices they make for themselves and their families at home. A healthy diet promotes well-being because it plays a major role in preventing or controlling many health conditions such as Type 2 diabetes, obesity, hypertension, and some heart diseases.

Abstract
This paper describes the approach and initial results of a trial utilizing artificial nest boxes to support the avian population for seed disbursal for vegetation restoration purposes. The study site is an onshore gas receiving facility (ORF) concession area, located within a globally recognised Key Biodiversity Area (KBA). By applying the mitigation hierarchy, the company has limited the residual impact on natural habitats and is enhancing the forest estate through active and passive forest restoration. Historic land use has resulted in a paucity of natural breeding spaces for cavity-nesting birds, potentially limiting avian abundance and diversity. Artificial nesting boxes are a common technology in newly established and managed woodlands and are considered highly effective at supporting avian conservation objectives. Their effectiveness is correlated with imitating the size, shape and climatic conditions of natural cavities. Hence a trial was necessary to identify the most suitable design for the conditions and species encountered in the project location.
Sixty-five nest boxes were installed with the design, construction material and entrance diameter among variables trialled. Those crafted from a mud-cement mixture showed the greatest durability, although those constructed from solid wood performed adequately and were easier to construct. Nest box occupancy after a year or less remained low; only three of the 65 boxes installed show clear or potential signs of use. Potential occupants showed preference for a "standard" box design. No preference for entrance size or construction material could be construed.
Arthropods were identified residing in the boxes on 10 occasions. Their impact on bird occupancy is uncertain, however insects may hasten the destruction of wooden boxes and render the box uninhabitable for nesting birds or hatchlings. The project also encountered unexpected losses and severe damage to 25 nest boxes, 20 of which were unable to be located and hence could not be assessed.
Although very early in the project, recommendations from these monitoring results can enhance the effectiveness of the technology for other users. Recommendations to improve occupancy include increasing the installation height, checking the correct orientation for the location and minimising the opportunity for eusocial insects to access the nests. Boxes should be securely fixed in place, preferably with two methods to allow for functional redundancy. Finally, engagement with local communities is a critical consideration; projects engaging in the use of this technology should not overlook the need to identify and address negative perceptions or misunderstandings that may negatively affect their use.
E&P Operations in Water Stressed Areas: An Approach to the Identification, Selection and Implementation of Initiatives for a Sustainable Water Management, Withdrawal Reduction and Water Valorization

Published: September 2024

Water is one of earth's most critical resources, and water scarcity represents an increasing problem worldwide. Demographic growth and economic development are putting unprecedented pressure on water resources, especially in arid regions. Water is crucial for many sectors, and it is also fundamental to meet personal and household needs, for energy and industrial production, to maintain important water-dependent ecosystems and ecosystem services.
Water plays a key role in all the phases of the Oil and Gas business, because of the large amounts of this resource that should be managed, both with respect to withdrawals and to disposal. For these reasons, it is essential to adopt a well-defined and sound approach in order to protect the water resource, also considering that often Oil and Gas activities take place in arid regions.
All these aspects require an integrated and inclusive approach, able to build resilience against worsening factors.
Reconciliation of Source-Level Methane Emissions Measurement with Site-Level Measurement Using a Drone-Mounted Sensor: New Insights for Standardisation and Global Deployment
Authors: Stocker I. , Evans P. , Jupp M. , Bose R. , Smith B. 
Published: September 2024

AbstractAccurate and transparent reporting of methane emissions is vital for targeted and defensible methane reductions in the energy sector. This is recognised in the United Nations’ new reporting framework (OGMP2.0) where measurement-based reporting of methane emissions that is accompanied with a statement of reconciliation constitutes the highest level of conformance (‘level 5’). A fully traceable top-down measurement system suitable for onshore and offshore deployment was developed to conform with OGMP2.0 level 5 expectations. Site-level methane emissions are measured by means of a drone-mounted methane sensor flown downwind of oil and gas production facilities. The sensor was deployed on quadcopter and fixed-wing drones with comparable results. Atmospheric methane concentrations were converted into an emission rate through mass balance calculations, considering meteorological parameters. Results from 11 offshore surveys acquired between 2021 and 2023 showed generally low emissions of less than 40 kg/h, with two outliers measured at 106 ± 31 kg/h and 347 ± 97 kg/h respectively. Emissions followed a ‘fat-tail’ distribution with 27% of sites accounting for 87% of the total methane emissions in the sample, highlighting the value of top-down measurement in identifying abatement opportunities. Two-thirds of sites measured in 2023 were successfully reconciled to OGMP2.0 level 5. The analysis emphasized the importance of high-quality source-level data for successful reconciliation and sites where such data is available should be prioritized when scheduling top-down measurements. A successful top-down strategy should follow a process of continuous improvement that considers emissions materiality, range of emission rates under normal operating conditions, demonstrable quality of bottom-up inventories, and the option to group sites into representative populations. Standardisation and industry collaboration is needed to ensure consistency in the methodology of both the top-down measurement and reconciliation, including application of uncertainty, which is key for transparent, traceable, and credible reporting of methane emissions from oil and gas facilities.
