Abstract After two years of development, the GAIA Explorer is now ready to assist Geoscientists at Total! This knowledge platform works like a little Google, but with a focus solely on Geosciences - for the time being. The main goal of the GAIA Explorer is to save time finding the right information. Therefore, it is particularly useful for datarooms or after business acquisitions to quickly digest the knowledge, but also for feeding databases, exploration syntheses, reservoir studies, or even staff onboarding specially when remote working. With this additional time, Geoscientists can focus on tasks with added value, such as to synthesize, find analogies or propose alternative scenarios. This new companion automatically organizes and extracts knowledge from a large number of unstructured technical documents by using Machine Learning (ML). All the models relie on Google Cloud Platform (GCP) and have been trained on our own datasets, which cover main petroleum domains such as geosciences and operations. First, the layout of more than 75,000 document pages were analyzed for training a segmentation model, which extracts three types of content (text, images and tables). Secondly, the text content extracted from about 6,500 documents labelled amongst 30 classes was used to train a model for document classification. Thirdly, more than 55,000 images were categorized amongst 45 classes to customize a model of image classification covering a large panel of figures such as maps, logs, seismic sections, or core pictures. Finally, all the terms (n-grams) extracted from objects are compared with an inhouse thesaurus to automatically tag related topics such as basin, field, geological formation, acquisition, measure. All these elementary bricks are connected and used for feeding a knowledge database that can be quickly and exhaustively searched. Today, the GAIA Explorer searches within texts, images and tables from a corpus (document collection), which can be made up of both technical and operational reports, meeting presentations and academic publications. By combining queries (keywords or natural language) with a large array of filters (by classes and topics), the outcomes are easily refined and exploitable. Since the release of a production version in February 2021 at Total, about 180 users for 30 projects regularly use the tool for exploration and development purposes. This first version is following a continuous training cycle including active learning and, preliminary user feedback is good and admits that some information would have been difficult to locate without the GAIA Explorer. In the future, the GAIA Explorer could be significantly improved by implementing knowledge graph based on an ontology dedicated specific to petroleum domains. Along with the help of Specialists in related activities such as drilling, project or contract, the tool could cover the complete range of upstream topics and be useful for other business with time.

Oil and gas production in Canada’s west has led to the need for a significant increase in pipeline capacity to reach export markets. Current proposals from major oil and gas transportation companies include numerous large diameter pipelines across the Rocky Mountains to port locations on the coast of British Columbia (BC), Canada. The large scale of these projects and the rugged terrain they cross lead to numerous challenges not typically faced with conventional cross-country pipelines across the plains. The logistics and access challenges faced by these mountain pipeline projects require significant pre-planning and assessment, to determine the timing, cost, regulatory and environmental impacts. The logistics of pipeline construction projects mainly encompasses the transportation of pipe and pipeline materials, construction equipment and supplies, and personnel from point of manufacture or point of supply to the right-of-way (ROW) or construction area. These logistics movement revolve around the available types of access routes and seasonal constraints. Pipeline contractors and logistics companies have vast experience in moving this type of large equipment, however regulatory constraints and environmental restrictions in some locations will lead to significant pre-planning, permitting and additional time and cost for material movement. In addition, seasonal constraints limit available transportation windows. The types of access vary greatly in mountain pipeline projects. In BC, the majority of off-highway roads and bridges were originally constructed for the forestry industry, which transports logs downhill whereas the pipeline industry transports large equipment and pipeline materials in both directions and specifically hauls pipe uphill. The capacity, current state and location of these off-highway roads must be assessed very early in the process to determine viability and/or potential options for construction access. Regulatory requirements, environmental restrictions, season of use restrictions and road design must all be considered when examining the use of or upgrade of existing access roads and bridges. These same restrictions are even more critical to the construction of new access roads and bridges. The logistics and access challenges facing the construction of large diameter mountain pipelines in Western Canada can be managed with proper and timely planning. The cost of the logistics and access required for construction of these proposed pipeline projects will typically be greater than for traditional pipelines, but the key constraint is the considerable time requirement to construct the required new access and pre-position the appropriate material to meet the construction schedule. The entire project team, including design engineers, construction and logistics planners, and material suppliers must be involved in the planning stages to ensure a cohesive strategy and schedule. This paper will present the typical challenges faced in access and logistics for large diameter mountain pipelines, and a process for developing a comprehensive plan for their execution.

The Coronavirus Disease (COVID-19) is inarguably the most disrupting occurrence in human affairs since the World War II. This virus left governments, communities and systems with the legal, social and moral duties to protect from its impacts. However, some of the approaches adopted towards protecting the victims, potential victims, and the entire society, especially in Nigeria, caused more harm than the disease itself. This work reviews the impact of the curtailment measures adopted by governments in Nigeria and their adverse bearing on human rights, especially the right to life as a sacrosanct and universal right. It further examines how law enforcement agencies’ operations - within the confines of the institutional and international best practices - their non-adherence to the rules of engagement or principles of ethical operations have resulted in the violation of human rights, rather than protecting them. It also analyses the impact of the virus on the right to health and access to medical facilities in times of emergencies in Nigeria and concludes that both rights were either violated or not realized within the context of the ‘war’ against the COVID-19 pandemic. This work advocates for the continuous training on human rights responsibilities of law enforcement agents, a more rigorous recruitment process with a minimum qualification from school certificate to ordinary national diploma, the use of video camera in the course of operations, among others that would help safeguard the rights of citizens in times of emergencies like the COVID-19.

<p>Studies have shown the benefits of convection-permitting downscaling at the seasonal scale using limited-area models. To evaluate the performance with real forecasts as boundary conditions, four members of the SEAS5 global ensemble were dynamically downscaled over Ethiopia during June, July, and August 2018 at a 3-km resolution. We used a multi‐physics ensemble based on the WRF model to compare the effects of boundary conditions and physics <span><span>parametrization</span></span> producing 16 ensemble members. With ECMWF analyses as a reference, SEAS5 averaged to a +0.17°C bias over Ethiopia whereas WRF resulted in +1.14°C. With respect to precipitation, the WRF model simulated 264 mm compared to 248 mm for SEAS5 and 236 mm for GPM-IMERG. The maximum northward extension of the tropical rain belt decreased by about 2° in both models. Downscaling enhanced the ensemble spread in precipitation by 60% on average, correcting the SEAS5 underdispersion. The WRF ensemble spread over Ethiopia was mostly generated by the perturbed boundary conditions, as their effect is often 50% larger than the physics‐induced variability. The results indicate that boundary condition perturbations are necessary, although not always sufficient, to generate the right amount of ensemble spread in a limited-area model with complex topography. The next step is to use specific methods to calculate the added value provided by the downscaling.</p>

The article considers features of cadastral valuation of agricultural lands occupied by water bodies. The research is based on natural water bodies of the Samara region water fund. A methodology for determining the cadastral value of agricultural lands occupied by artificial water bodies is proposed. The methodology links the land value with the size of the land plot, profit and such objects as dams and other hydraulic structures located within the land plot. The paper confirmed the suggestion that the owner of the land that shall be used for the construction of a pond has the right to the added value of land in the amount of return rate of contributed capital (26.28%). The cadastral value of 1 square meter of agricultural land is 3.11 rubles.

In this short essay I argue that the main insight of Murphy and Nagel’s book, The Myth of Ownership, that people have no right to their pre-tax income, is not supported by their claim that the right to private property is not a natural right. The non-naturalness of the right to private property, I argue, is irrelevant to their moral argument. The plausibility of their moral conclusion derives from the thesis (which they also seem to endorse) that people have a right to the fruits of their labor, maintaining, however, that there is no possible conception, morally speaking, of what the fruits of one's labor are, independent of a system of legal and social norms that constitute the terms of fair bargaining, pricing, etc. People can only have a right to a fair assessment of the added value of their labor, and the latter cannot make any sense independent of the entire system of norms prevailing in the relevant society. I argue that this last conclusion is not affected by the nature of the right to private property.

Using gaze-contingent display changes in the boundary paradigm during sentence reading, it has recently been shown that parafoveal word-processing difficulties affect fixations on words to the right of the boundary. Current interpretations of this post-boundary preview difficulty effect range from delayed parafoveal-on-foveal effects in parallel word-processing models to forced fixations in serial word-processing models. However, these findings are based on an experimental design that, while allowing to isolate preview difficulty effects, might have established a bias with respect to asymmetries in parafoveal preview benefit for high-frequent and low-frequent target words. Here, we present a revision of this paradigm varying the preview’s lexical frequency and keeping the target word constant. We found substantial effects of the preview difficulty in fixation durations after the boundary confirming that preview processing affects the oculomotor decisions not only via trans-saccadic integration of preview and target word information. An additional time-course analysis showed that the preview difficulty effect was significant across the full fixation duration distribution on the target word without any evidence on the pretarget word before the boundary. We discuss implications of the accumulating evidence of post-boundary preview difficulty effects for models of eye movement control during reading.

Background: The narrow link between practice, education, and research is essential to palliative care development. In Portugal, academic postgraduate publications are the main booster for palliative care research. Methods: This is a bibliometric study that aims to identify Portuguese palliative care postgraduate academic work published in electronic academic repositories between 2000 and 2015. Results: 488 publications were identified. The number of publications has increased, especially in the last five years. The most frequently used method was quantitative, healthcare professionals were the most studied participants, and psychological and psychiatric aspects of care comprised the most current theme. Practice-based priorities are financial costs and benefits of palliative care, awareness and understanding of palliative care, underserved populations, best practices, communication, and palliative care in nonhospital settings. Conclusion: The number of palliative care postgraduate academic publications has increased in Portugal in the past few years. There is academic production in the eight domains of quality palliative care and on the three levels of recommendation for practice-based research priorities. The major research gaps in Portugal are at the system and societal context levels.
