In the US West, water stories are often aqueduct stories, narratives of moving the vital resource from one place to another. This paper, in contrast, explores nascent efforts to keep the water still, in the name of helping buffer cities from the anticipated impacts of climate change. Scripted as potential holding sites for an urban water reserve, aquifers and the task of filling them now orient a range of policies and material investments across Southern California. Building on writings that explore the multi-scalar politics of storing and stockpiling vaccines, resources, and lively or uncooperative commodities, this analysis approaches storage as a key moment within circulation, a dynamic, constitutive stillness that conditions flows. Three early-stage subterranean water stockpiling projects connected to the City of Los Angeles are explored, and used to demonstrate how the pursuit of storage is remaking material and political relationships within and between urban jurisdictions, while complicating long-fraught urban–rural relations within the region's waterscape. These shifts suggest the value of reorienting the notion of the urbanization of nature to better attend to the geographies of resource storage, in addition to those of resource flows and circulations.

The relevance of the statistic begins when in the minds of postindustrial development the sphere of restaurant service is intensively developing, new services and technology have appeared, and the globalization of the restaurant sector has made it possible to state the competitiveness of food in the restaurant sector. Yak galuz ekonomiki, Ukrainian restaurant service is guilty of more and more focus on consumer and interest of foreign tourists and survivors of life, economic economy and suspension. The main method is the statty є development of restaurant service (restaurantology) as a scientific and methodical basis for the development and promotion of services in the restaurant business, to enter the warehouse of the current economy of Ukraine. The statutes of the restaurant service policy are being formed (service policy in the restaurant service management) as the scientific basis of the restaurant business design and the evaluation of the quality of service in the restaurant service, the development of the sphere of service in the restaurant service, the development of the The market of this kind of services, the development of service and information technologies and communica- tions, is able to display the functional and decomposition of restaurants (complexes of restaurant services). The broken science theory of hotel service (hotel service) has not yet been formed, insufficiently rooted, not represented by the scientific spirit and numerical sub'ekts of the economy and the suspension, which is to work on the hope of the last guests. As a result of the abundant current nutrition and development of the sphere of hotel services, there can be no change without a theoretical rationalization of the day service and the development of scientific theory of services (hotel serviceology). At the same time, the advancement of the theoretical foundations of the sphere of hotel services is not only theoretical, but in the meaning of the world, applied value, some specificity of technology in the sphere of hotel management services, resource storage and production of the sphere of production

A fraction of rainfall drains to the soil surface down tree stems (as “stemflow”), and the resulting stemflow waters can be highly enriched with dissolved nutrients due to prolonged bark contact. To date, stemflow chemistry has been examined mostly in regards to the external morphology of the bark, while its relationship with bark anatomy has received little attention. Arguably, this represents a major knowledge gap, because bark anatomical traits are linked to the storage and transport of soluble (and insoluble) organic materials, and control the proximity of these materials to passing stemflow waters. To initiate this line of investigation, here, we examine bark-water leaching rates for common leachable macronutrient ions (Mg2+, Ca2+, and K+) across six different tree species with varying bark anatomical traits (four deciduous broadleaved and two evergreen coniferous species). These different bark types were subjected to laboratory experiments, including observations of bark anatomy and soaking experiments. Laboratory-derived estimates of leaching rates for Mg2+, Ca2+, and K+ were then analyzed alongside bark anatomical traits. Leaching rates of Mg2+ and Ca2+ appear to be controlled by the thickness of the rhytidome and periderm; while K+ leaching rates appeared to be driven by the presence of cellular structures associated with resource storage (parenchyma) and transfer (sieve cells). Other species-specific results are also identified and discussed. These results suggest that the anatomical features of bark and the concentration of leachable macronutrient ions in stemflow are related, and that these relationships may be important to understand nutrient cycle through the bark. We also conclude that future work on the mechanisms underlying stemflow solute enrichment should consider bark anatomy.

Resource allocation to different plant tissues is likely to be affected by high investment into fruit production during mast years. However, there is a large knowledge gap concerning species-specific differences in resource dynamics. We investigated the influence of mast years on stem growth, leaf production, and leaf carbon (C), nitrogen (N), and phosphorus (P) concentrations and contents in Fagus sylvatica, Quercus petraea, and Q. robur at continental and climate region scales using long-term data from the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) and similar datasets. We discussed the results in the light of opposing resource dynamics hypotheses: (i) resource accumulation before mast years and exhaustion after mast years (resource storage hypothesis), (ii) shifting resources from vegetative to generative compartments (resource switching hypothesis), and (iii) investing resources concurrently in both vegetative and generative compartments (resource matching hypothesis). Linear mixed-effects modelling (LMM) showed that both stem growth and leaf production were negatively influenced by weather conditions which simultaneously lead to high fruit production. Thus, the impact of generative on vegetative growth is intermixed with effects of environmental factors. Superposed epoch analyses and LMM showed that for mast behaviour in F. sylvatica, there are indicators supporting the resource storage and the resource switching hypotheses. Before mast years, resources were accumulated, while during mast years resources switched from vegetative to generative tissues with reduced stem and leaf growth. For the Quercus species, stem growth was reduced after mast years, which supports the resource storage hypothesis. LMM showed that leaf C concentrations did not change with increasing fruit production in neither species. Leaf N and P concentrations increased in F. sylvatica, but not in Quercus species. Leaf N and P contents decreased with increasing fruit production in all species, as did leaf C content in F. sylvatica. Overall, our findings suggest different resource dynamics strategies in F. sylvatica and Quercus species, which might lead to differences in their adaptive capacity to a changing climate.

Abstract In angiosperms, clonality is a derived trait and is present in several wild and cultivated plant species. Therefore, over time, natural and artificial selection have optimized the novel function of being a propagule in organs whose previous function was exclusively vegetative. Although increased resource storage and resistance to desiccation have been suggested as the main adaptations for clonality in crops, there is little empirical evidence to support this assertion. Here, I assessed the changes that the stems of chaya (Cnidoscolus aconitifolius), a clonal crop, have undergone through domestication and evaluated their performance as propagules. To infer which traits have been optimized by artificial selection, I compared stem traits and their performance in root development and clone survival between wild and domesticated plants. I found that, relative to their wild ancestors, the stems of domesticated chaya have a greater storage capacity for water and starch. Additionally, the stems of domesticated plants produced more roots, shoots and leaves, and their clones lived longer. My results strongly suggest that artificial selection has optimized water and starch storage by stems in chaya. Because these traits also confer greater fitness, they could be considered adaptations to clonal propagation.

The response rate and performance indicators of enterprise resource calls have become an important part of measuring the difference in enterprise user experience. An efficient corporate shared resource calling system can significantly improve the office efficiency of corporate users and significantly improve the fluency of corporate users' resource calling. Hadoop has powerful data integration and analysis capabilities in resource extraction, while R has excellent statistical capabilities and resource personalized decomposition and display capabilities in data calling. This article will propose an integration plan for enterprise shared resource invocation based on Hadoop and R to further improve the efficiency of enterprise users' shared resource utilization, improve the efficiency of system operation, and bring enterprise users a higher level of user experience. First, we use Hadoop to extract the corporate shared resources required by corporate users from the nearby resource storage computer room and terminal equipment to increase the call rate, and use the R function attribute to convert the user’s search results into linear correlations, according to the correlation The strong and weak principles are displayed in order to improve the corresponding speed and experience. This article proposes feasible solutions to the shortcomings in the current enterprise shared resource invocation. We can use public data sets to perform personalized regression analysis on user needs, and optimize and integrate most relevant information.

Health equity is a very important part of social equity. The outbreak of the novel coronavirus pneumonia (COVID-19) in a short period of time exposed the problems existing in the allocation of medical resources and the response to major public health emergencies in China. By using Kernel density estimation and Data envelopment analysis (DEA), it is found that the allocation and imbalance of medical resources in China are greatly different among regions, and the polarization phenomenon is obvious. As an important part of the information technology system, blockchain technology is characterized by decentralization and non-tampering. It can realize sharing of medical resources through a mechanism of resource storage, circulation, supervision, and protection. The construction of a medical resource sharing mechanism under the condition of blockchain technology will greatly improve the degree of medical resource sharing, will narrow the differences in resource allocation between regions, and can effectively respond to an outbreak of major public health emergencies.

ABSTRACT Soil is one of the most diverse microbial habitats on Earth. While the distribution and abundance of microbial taxa in surface soils have been well described, the phylogenetic and functional diversity of bacteria and archaea in deep-soil strata remains unexplored. Brewer et al. (mBio 10:e01318-19, 2019, https://doi.org/10.1128/mBio.01318-19) documented consistent shifts in the composition and genomic attributes of microbial communities as a function of depth in 20 soil pits that spanned a range of ecosystems across North America. The unique microorganisms found in deep soils appear to be adapted to conditions of low energy based on the recovery of genes that code for traits such as internal resource storage, mixotrophy, and dormancy.
