This article examines the relationship between heritage and decoloniality, focusing on how colonial legacies continue to impact public spaces and social structures. The authors argue for the need to challenge racialized social systems and exclusionary regimes through grassroots activism and protests. They also explore the politics of representation, the decolonization of heritage institutions and practices, and the importance of interdisciplinary collaboration and diverse perspectives. The article includes case studies, interviews, and reflections on the complexities of heritage and decoloniality. It calls for further exploration of the different ways decoloniality is mobilized, the concrete manifestations of decoloniality in heritage practice, and the practical implications for transformative actions. The text emphasizes the importance of recognizing power structures, diverse perspectives, and the complexities of decoloniality in heritage practices. [Extracted from the article]

Large-scale disasters have exposed vulnerabilities in energy systems and interdependent infrastructure, underscoring the importance of proactively mitigating risks to critical infrastructure. This paper focuses on strengthening power system planning by incorporating the costs associated with prolonged and extensive power interruptions to bolster resilience. To achieve this, duration-dependent customer damage functions are developed, capturing the direct, indirect, and societal impacts of power interruptions, ranging from short, localized events to widespread and long-duration ones. The research methodology is applied to three islanded communities facing substantial resilience challenges with limited data availability. Three customer interruption cost surveys are conducted with local electricity customers, yielding valuable insights into duration-dependent customer damage functions for direct, indirect, and monetizable societal costs. Significantly, the power interruption cost estimates derived from these functions vary considerably from those in the contiguous U.S. and even between the different islanded communities, reflecting their distinct hazard profiles and geographical characteristics. In conclusion, this study demonstrates the potential of duration-dependent customer damage functions to enhance power system resilience. It also identifies several areas for further research, paving the way for a more robust and resilient power infrastructure. [ABSTRACT FROM AUTHOR]

Introduction: Phosphorus (P) deficiency in plants creates a variety of metabolic perturbations that decrease photosynthesis and growth. Phosphorus deficiency is especially challenging for the production of bioenergy feedstock plantation species, such as poplars (Populus spp.), where fertilization may not be practically or economically feasible. While the phenotypic effects of P deficiency are well known, the molecular mechanisms underlying whole-plant and tissue-specific responses to P deficiency, and in particular the responses of commercially valuable hardwoods, are less studied. Methods: We used a multi-tissue and multi-omics approach using transcriptomic, proteomic, and metabolomic analyses of the leaves and roots of black cottonwood (Populus trichocarpa) seedlings grown under P-deficient (5 µM P) and replete (100 µM P) conditions to assess this knowledge gap and to identify potential gene targets for selection for P efficiency. Results: In comparison to seedlings grown at 100 µM P, P-deficient seedlings exhibited reduced dry biomass, altered chlorophyll fluorescence, and reduced tissue P concentrations. In line with these observations, growth, C metabolism, and photosynthesis pathways were downregulated in the transcriptome of the Pdeficient plants. Additionally, we found evidence of strong lipid remodeling in the leaves. Metabolomic data showed that the roots of P-deficient plants had a greater relative abundance of phosphate ion, which may reflect extensive degradation of P-rich metabolites in plants exposed to long-term P-deficiency. With the notable exception of the KEGG pathway for Starch and Sucrose Metabolism (map00500), the responses of the transcriptome and the metabolome to P deficiency were consistent with one another. No significant changes in the proteome were detected in response to P deficiency. Discussion and conclusion: Collectively, our multi-omic and multi-tissue approach enabled the identification of important metabolic and regulatory pathways regulated across tissues at the molecular level that will be important avenues to further evaluate for P efficiency. These included stress-mediating systems associated with reactive oxygen species maintenance, lipid remodeling within tissues, and systems involved in P scavenging from the rhizosphere.

Key highlights from U.S. Energy Service Company (ESCO) Industry: Recent Market Trends•After more than two decades of year-over-year growth, ESCO industry revenues appeared to flatten between 2011 and 2014. ESCOs reported 2014 industry revenue of approximately $5.3 billion, the same as revenues reported in 2011. •Based on ESCOs’ 3-year growth projections, ESCOs expect total annual industry revenues to be approximately $7.6 billion for 2017, which equates to an average annual growth rate of ~13% for the three years 2015-2017.•Public and institutional market sectors accounted for 85% of industry revenue in 2014, which is consistent with previous study findings.•Performance contracting generated 75% ($3.7 billion) of industry revenue in 2014, which is somewhat higher than the 69% share for performance contracting reported in 2011 and 2008. Design-build projects contributed the next largest share of 2014 revenue (16% or ~$800 million), followed distantly by consulting services (5%), onsite generation power purchase agreements (3%) and other activities (2%).•The share of industry revenue contributed by large ESCOs (annual energy services revenue of $300M or greater) declined somewhat between 2011 and 2014. Accordingly, medium-sized ESCOs as a group (annual revenue between $100M and $299M) increased market share from 29% in 2011 to 33% in 2014. Small ESCOs (annual revenue

Implementation of carbon capture and sequestration (CCS) will increase water demand due to the cooling water requirements of CO2 capture equipment. If the captured CO2 is injected into saline aquifers for sequestration, brine may be extracted to manage the aquifer pressure, and can be desalinated to provide additional freshwater supply. We conduct a geospatial analysis to determine how CCS may affect local water supply and demand across the contiguous United States. We calculate baseline indices for each county in the year 2005, and project future water supply and demand with and without CCS through 2030. We conduct sensitivity analyses to identify the system parameters that most significantly affect water balance. Water supply changes due to inter-annual variability and projected climate change are overwhelmingly the most significant sources of variation. CCS can have strong local effects on water supply and demand, but overall it has a modest effect on water balances.
