Published: November 2019

Abstract
The urban water environment rehabilitation project is a comprehensive strategic social project with large investment, wide scope and complicated construction conditions, which determines the uncertainty and particularity of the quality management of urban water environment rehabilitation projects. In order to improve the quality management level of urban water environment rehabilitation projects and promote urban water environment rehabilitation, this paper analyzes the characteristics of quality management of urban water environment rehabilitation projects from the viewpoint of the total quality management. Taking the Maozhou River urban water environment rehabilitation project in Shenzhen, Guangdong, China as an example, using the total quality management theory and causal analysis, the authors summed up the new quality management model, dual-collaborative quality management, for the water environment rehabilitation project, and some new technologies such as resident supervision system, closed circuit television inspection and data analysis technology were applied.

Abstract
There are a large number of hazard sources in the construction site, and each hazard source may cause a safety accident. Therefore, timely and accurate identification of hazard sources becomes a necessary for safety management at the construction site. Along with the characteristics of the construction site of the Maozhou River Rehabilitation Project, from the four aspects of management, people, environment and objects, the causal analysis method is used to analyze the hazard sources of safety accident at the construction site. According to the analyzed hazard sources, the total safety management of the project was realized through the PDCA cycle.
Evaluation of groundwater remediation strategies at petroleum contaminated sites based on groundwater modelling approach
Authors: Yang L H , Jing L X , Zheng C M 
Published: November 2019

Abstract
Based on the hydrogeological survey and groundwater environmental investigation at an abandoned oil refinement factory, a site-specific groundwater flow and solute transport model was constructed to support the development of groundwater remediation strategy. The contamination plume of Benzene is simulated and predicted in 30-year scale for designed scenarios. The results indicate that the groundwater quality takes long time to recover even though the contamination source above the water table is cleaned up. This is due to the large quantity of solved contaminants in local aquifer, and additionally the contribution from groundwater circulation is limited. The groundwater remediation actions, such as Pump & Treat (P&T) and In-Situ Chemical Oxidation (ISCO) could greatly improve the groundwater quality. However, under the site-specific circumstance, the ISCO technique is efficient but costly; the P&T takes longer time but more flexible and effective in protecting target drinking wells. Therefore, a combined remediation approach including both P&T and ISCO would be recommended. In summary, by the quantitative analysis regarding the feasibility, time scale, and effectiveness for the potential applicable remediation approaches, the groundwater modelling framework provided a insight on the system behavior and reliable support for the decision making in groundwater protection.

Abstract
Water resources play an irreplaceable role in the survival, life and production of human being. It is the foundation of social stability and economic development. The sustainable utilization of water resources is one of the important factors affecting social and economic development. The water resources of various administrative regions in Gansu Province in 2006-2015 were evaluated by using evaluation indexes such as water resources development and utilization rate, water resources ecological capacity and sustainable development index and other evaluation indicators, the results show that: Gansu Province has a higher level of water resources development and utilization, but the amount of water resources cannot meet the current water load, and the water shortage in some areas is serious; The ecological footprint of water resources in Gansu Province is less than its carrying capacity. However, the water resources are in a sustainable use state. Considering the increasing demand for water resources for economic and social development activities, it needs to further consider the cost of water in the future development process; the water resources in Gansu Province can continue to develop, its development conditions are optimistic, and water resources can effectively guarantee the rapid development of the economy and society.

Authors: Zhang W , Wang X , Zhai T Y , Peng Z Y 
Published: November 2019

Abstract
Enter the new era, renewable energy is constrained by regional heterogeneity, such as resource distribution, market structure and industrial environment, and its spatial heterogeneity is becoming increasingly prominent. To explore the spatial agglomeration effect of renewable energy development, this paper builds a spatial panel econometric model to explore the driving factors of renewable energy industry development on the basis of analysing the spatial correlation of renewable energy. The results show that the development of the renewable energy industry has path dependence and spatial stability, and there is an industrial agglomeration effect in spatial development. In addition, the emission of exhaust gas is negatively correlated with the development of the renewable energy industry, and the power consumption of renewable energy and the reserve of non-renewable resources will significantly promote the development of renewable energy industry. Meanwhile, government investment in environmental protection is not significantly correlated with the development of renewable energy industry. This study can provide theoretical guidance and practical support for promoting the development of China’s renewable energy industry.

Resilience and Function in Adults With Chronic Physical Disabilities: A Cross-Lagged Panel Design
Authors: Battalio Samuel L , Tang Connie L , Jensen Mark P 
Published: November 2019

AbstractBackgroundResilience is a psychological construct referring to one’s positive adaptation in response to adversity. Evidence suggests that resilience may contribute to various function domains in adults with chronic physical disabilities.PurposeTo test hypothesized temporal associations between resilience and four function domains (anxiety, depression, social role satisfaction, and physical function) in individuals with chronic physical disabilities.MethodsParticipants were 1,574 adults with one of four chronic physical disabilities (spinal cord injury, muscular dystrophy, multiple sclerosis, or postpolio myelitis syndrome) who were participating in a large, ongoing USA-based longitudinal survey study. Three surveys were mailed on an approximately yearly basis. Resilience was assessed using the Connor–Davidson Resilience Scale 10-item (CDRSC-10) and each function domain was assessed using the respective Patient Reported Outcome Measurement System (PROMIS) short-form.ResultsCross-lagged path models evidenced statistically significant reciprocal relationships between resilience and each function domain except physical function. The standardized lagged coefficients corresponding to resilience predicting social role satisfaction (T1–T2 = 0.09, T2–T3 = 0.09) had similar effect sizes as those corresponding to social role satisfaction predicting resilience (T1–T2 = 0.11, T2–T3 = 0.04), although resilience was a slightly stronger predictor in the second lag. In models assessing psychological function, resilience was a stronger predictor of later psychological function (resilience-to-anxiety, T1–T2 = −0.15, T2–T3 = −0.11; resilience-to-depression, T1–T2 = −0.21, T2–T3 = −0.13) than the inverse (anxiety-to-resilience, T1–T2 = −0.11, T2–T3 = −0.06; depression-to-resilience, T1–T2 = −0.12, T2–T3 = −0.05).ConclusionsThe study findings suggest that resilience is a significant prospective predictor of psychological and social function over time in individuals with chronic physical disabilities.
Roles of Two Major Alcohol Dehydrogenases, ADH1 (Class I) and ADH3 (Class III), in the Adaptive Enhancement of Alcohol Metabolism Induced by Chronic Alcohol Consumption in Mice

Published: November 2019

Abstract

Aims
It is still unclear which enzymes contribute to the adaptive enhancement of alcohol metabolism by chronic alcohol consumption (CAC). ADH1 (Class I) has the lowest Km for ethanol and the highest sensitivity for 4-methylpyrazole (4MP) among ADH isozymes, while ADH3 (Class III) has the highest Km and the lowest sensitivity. We investigated how these two major ADHs relate to the adaptive enhancement of alcohol metabolism.

Methods
Male mice with different ADH genotypes (WT, Adh1−/− and Adh3−/−) were subjected to CAC experiment using a 10% ethanol solution for 1 month. Alcohol elimination rate (AER) was measured after ethanol injection at a 4.0 g/kg dose. 4MP-sensitive and -insensitive AERs were measured by the simultaneous administration of 4MP at a dose of 0.5 mmol/kg in order to estimate ADH1 and non-ADH1 pathways.

Results
AER was enhanced by CAC in all ADH genotypes, especially more than twofold in Adh1−/− mice, with increasing ADH1 and/or ADH3 liver contents, but not CYP2E1 content. 4MP-sensitive AER was also increased by CAC in WT and Adh3−/− strains, which was greater in Adh3−/− than in WT mice. The sensitive AER was increased even in Adh1−/− mice probably due to the increase in ADH3, which is semi-sensitive for 4MP. 4MP-insensitive AER was also increased in WT and Adh1−/− by CAC, but not in Adh3−/− mice.

Conclusion
ADH1 contributes to the enhancement of alcohol metabolism by CAC, particularly in the absence of ADH3. ADH3 also contributes to the enhancement as a non-ADH1 pathway, especially in the absence of ADH1.

Abstract

Background and Aims
The distribution of cytotypes and its potential correlation with environmental variables represent a cornerstone to understanding the origin and maintenance of polyploid lineages. Although many studies have addressed this question in single species at a regional scale, only a few have attempted to decipher this enigma in groups of closely related species at a broad intercontinental geographical scale. Here, we consider ca. 20 species of a diploid-polyploid complex (Veronica subsect. Pentasepalae) of recent and rapid diversification represented in Europe and North Africa to study the frequency and distribution of cytotypes and its relationship with environmental variables.

Methods
A total of 680 individuals (207 populations) were sampled. Ploidy levels were determined using flow cytometry. Ecological differentiation among cytotypes was tested using climatic and environmental variables related to temperature, precipitation, vegetation and biogeographical region, among others, and by performing univariate and multivariate (constrained PCoA) analyses.

Key Results
Four ploidy levels (2x, 4x, 6x, 8x) were found and genome downsizing was observed to occur within the group. Plants of different ploidy level are ecologically differentiated, with hexaploids and octoploids occurring in wetter and colder habitats with a higher seasonality than diploids. A south-to-north distribution pattern was found, with diploids occupying southern refugial areas and octoploids being more frequent in northern regions of Europe above the permafrost boundary.

Conclusions
The distribution of cytotypes can be explained by ecological differentiation, the geographical position of refuge areas during the Quaternary climatic oscillations, as well as by ice and permafrost retreat patterns. The Balkan Peninsula constitutes the most important contact zone between cytotypes. This work provides the first comprehensive ploidy screening within V. subsect. Pentasepalae at a broad scale and indicates that polyploidy and genome downsizing might have contributed to the colonization of new habitats in a recently diverged polyploid complex.
Taxonomic weighting improves the accuracy of a gap-filling algorithm for metabolic models
Authors: Ong Wai Kit , Midford Peter E , Karp Peter D 
Published: November 2019

Abstract

Motivation
The increasing availability of annotated genome sequences enables construction of genome-scale metabolic networks, which are useful tools for studying organisms of interest. However, due to incomplete genome annotations, draft metabolic models contain gaps that must be filled in a time-consuming process before they are usable. Optimization-based algorithms that fill these gaps have been developed, however, gap-filling algorithms show significant error rates and often introduce incorrect reactions.

Results
Here, we present a new gap-filling method that computes the costs of candidate gap-filling reactions from a universal reaction database (MetaCyc) based on taxonomic information. When gap-filling a metabolic model for an organism M (such as Escherichia coli), the cost for reaction R is based on the frequency with which R occurs in other organisms within the phylum of M (in this case, Proteobacteria). The assumption behind this method is that different taxonomic groups are biased toward using different metabolic reactions. Evaluation of the new gap-filler on randomly degraded variants of the EcoCyc metabolic model for E.coli showed an increase in the average F1-score to 99.0 (when using the variable weights by frequency method at the phylum level), compared to 91.0 using the previous MetaFlux gap-filler and 80.3 using a basic gap-filler. Evaluation on two other microbial metabolic models showed similar improvements.

AbstractWhether an ecological community is controlled from above or below remains a popular framework that continues generating interesting research questions and takes on especially important meaning in agroecosystems. We describe the regulation from above of three coffee herbivores, a leaf herbivore (the green coffee scale, Coccus viridis), a seed predator (the coffee berry borer, Hypothenemus hampei), and a plant pathogen (the coffee rust disease, caused by Hemelia vastatrix) by various natural enemies, emphasizing the remarkable complexity involved. We emphasize the intersection of this classical question of ecology with the burgeoning field of complex systems, including references to chaos, critical transitions, hysteresis, basin or boundary collision, and spatial self-organization, all aimed at the applied question of pest control in the coffee agroecosystem.

Published: November 2019

Abstract
The Tricolored Blackbird (Agelaius tricolor) is a range-restricted, colonial-nesting species in decline. Colonies include tens of thousands of individuals that forage in the surrounding landscape, at times commuting miles between nesting and foraging grounds. We explored the role of landscape composition on colony occupancy and mapped core and potential spring foraging habitat in California, USA. We used observations of spring Tricolored Blackbird nesting colonies from 2008, 2011, and 2014 and characterized changes in the surrounding landscape during an extended drought. Then, we constructed occurrence and abundance models in order to map core foraging habitat across 4 ecoregions in California. Finally, we used simulated land cover changes to identify potential habitat under restoration scenarios. Across the 3 survey years, surface water declined over time at unoccupied colony locations but remained stable at occupied colony locations, confirming that permanent surface water was a critical feature of persistent Tricolored Blackbird colonies. Average percent cover of nearly all land cover types suitable for foraging, as well as frequency of dairies and median NDVI, were all higher in current or historical colony sites than elsewhere. The proportion of surrounding alfalfa, grasslands, and surface water were the elements of foraging habitat best able to predict Tricolored Blackbird early breeding season colony presence and colony size. Core foraging habitat covered over 6 million acres in the study region, but only 18% was occupied in 2014. This result suggests a need to study additional factors determining colony occurrence and persistence, such as landscape connectivity, distributions of nesting substrates, and risk from predators. The vast majority (93.1%) of Tricolored Blackbird core habitat occurred on private land; therefore, saving the species will require engagement and partnership with private landowners.

Published: November 2019

Abstract

Background
This study aimed to evaluate the predictive value of the domains of intrinsic capacity (ie, cognition, locomotion, sensory, vitality, and psychosocial) proposed by the World Health Organization (WHO) on the 3-year adverse health outcomes of nursing home residents.

Methods
A 3-year incidence of mortality, falls, repeated falls, and autonomy decline (ie, a one-unit increase in the Katz score) was assessed in a cohort of Belgian nursing home residents. Cognition was assessed using the Mini-Mental State Examination (MMSE). For locomotion, balance, gait speed and chair stand performance were evaluated by the Short Physical Performance Battery test. The sensory domain was measured using the Strawbridge questionnaire for audition and vision. For vitality, abdominal circumference, body mass index, nutritional status (by Mini Nutritional Assessment [MNA]) and handgrip strength were assessed. Psychosocial status was evaluated by the EQ-5D and the Center for Epidemiological Studies Depression scale. Missing data were handled by multiple imputations. Cox proportional hazard models, logistic regressions, and analysis of variance were used for the analyses.

Results
In the multivariable model, a one-unit increase in balance performance and in the nutrition score decreased the probability of death by 12% (Hazard ratio [HR] = 0.88; 95% confidence interval [CI] 0.78–0.99) and 4% (HR = 0.96; 95% CI 0.93–0.99), respectively. The risk of falling decreased when there was a one-unit increase in balance performance (HR = 0.87, 95% CI 0.79–0.96) and in the nutrition score (HR = 0.96, 95% CI 0.93–0.98). No association was found for intrinsic capacity and repeated falls. Low scores in nutrition (odds ratio = 0.86, 95% CI 0.77–0.96) were associated with a higher probability of autonomy decline.

Conclusion
Some domains of intrinsic capacity predicted health outcomes among nursing home residents. Nutrition and balance should be regularly checked among this population.
