Multiple states of woody cover under similar climate conditions are found in both conceptual models and observations. Due to the limitation of the observed woody cover data set, it is unclear whether the observed bimodality is caused by the presence of multiple stable states or is due to dynamic growth processes of vegetation. In this study, we combine a woody cover data set with an above ground biomass data set to investigate the simultaneous occurrences of savanna and forest states under different precipitation forcing. To interpret the results we use a recently developed vegetation dynamics model (the Balanced Optimality Structure Vegetation Model), in which the effect of fires is included. Our results show that bimodality also exists in above ground biomass and retrieved vegetation structure. In addition, the observed savanna distribution can be understood as derived from a stable state and a slightly drifting (transient) state, the latter having the potential to shift to the forest state. Finally, the results indicate that vegetation structure (horizontal vs. vertical leaf extent) is a crucial component for the existence of bimodality
Seasonal evaluation of the land surface scheme HTESSEL against remote sensing derived energy fluxes of the Transdanubian region in Hungary
The skill of the land surface model HTESSEL is assessed to reproduce evaporation in response to land surface characteristics and atmospheric forcing, both being spatially variable. Evaporation estimates for the 2005 growing season are inferred from satellite observations of the Western part of Hungary and compared to model outcomes. Atmospheric forcings are obtained from a hindcast run with the Regional Climate Model RACMO2. Although HTESSEL slightly underpredicts the seasonal evaporative fraction as compared to satellite estimates, the mean, 10th and 90th percentile of this variable are of the same magnitude as the satellite observations. The initial water as stored in the soil and snow layer does not have a significant effect on the statistical properties of the evaporative fraction. However, the spatial distribution of the initial soil and snow water significantly affects the spatial distribution of the calculated evaporative fraction and the models ability to reproduce evaporation correctly in low precipitation areas in the considered region. HTESSEL performs weaker in dryer areas. In Western Hungary these areas are situated in the Danube valley, which is partly covered by irrigated cropland and which also may be affected by shallow groundwater. Incorporating (lateral) groundwater flow and irrigation, processes that are not included now, may improve HTESSELs ability to predict evaporation correctly. Evaluation of the model skills using other test areas and larger evaluation periods is needed to confirm the results. <br><br> Based on earlier sensitivity analysis, the effect of a number of modifications to HTESSEL has been assessed. A more physically based reduction function for dry soils has been introduced, the soil depth is made variable and the effect of swallow groundwater included. However, the combined modification does not lead to a significantly improved performance of HTESSEL
Patients undergoing elective coronary artery bypass grafting exhibit poor pre-operative intakes of fruit, vegetables, dietary fibre, fish and vitamin D
CHD may ensue from chronic systemic low-grade inflammation. Diet is a modifiable risk factor for both, and its optimisation may reduce post-operative mortality, atrial fibrillation and cognitive decline. In the present study, we investigated the usual dietary intakes of patients undergoing elective coronary artery bypass grafting (CABG), emphasising on food groups and nutrients with putative roles in the inflammatory/anti-inflammatory balance. From November 2012 to April 2013, we approached ninety-three consecutive patients (80% men) undergoing elective CABG. Of these, fifty-five were finally included (84% men, median age 69 years; range 46-84 years). The median BMI was 27 (range 18-36)kg/m(2). The dietary intake items were fruits (median 181g/d; range 0-433g/d), vegetables (median 115g/d; range 0-303g/d), dietary fibre (median 22g/d; range 9-45g/d), EPA+DHA (median 014g/d; range 001-106g/d), vitamin D (median 49g/d; range 19-112g/d), saturated fat (median 131% of energy (E%); range 9-23E%) and linoleic acid (LA; median 63E%; range 19-113E%). The percentages of patients with dietary intakes below recommendations were 62% (fruits; recommendation 200g/d), 87% (vegetables; recommendation 150-200g/d), 73% (dietary fibre; recommendation 30-45g/d), 91% (EPA+DHA; recommendation 045g/d), 98% (vitamin D; recommendation 10-20g/d) and 13% (LA; recommendation 5-10E%). The percentages of patients with dietary intakes above recommendations were 95% (saturated fat; recommendatio
UCAM: Urban Climate Assessment and Management : wijkgerichte beoordeling van hitte in de stad
De laatste jaren is er steeds meer aandacht voor stedelijke hitte. Het weer in de stad is een dynamisch micro-meteorologisch systeem. De stedelijke omgeving heeft op veel manieren een invloed op dit systeem. Ongeveer alle fysieke aspecten van een wijk hebben in meer of mindere mate een invloed op de stralingsbalans, temperatuur en wind. Gezamenlijk met de aanwezige milieufactoren in de stad, denk aan luchtverontreiniging, verslechtert het leefmi- lieu tijdens hittegolven. Het leefmilieu tijdens hittegolven heeft op veel verschillende manie- ren een negatieve uitwerking op de economie en de volksgezondheid. In dit project is nagegaan welke belemmeringen er zijn ten aanzien de beoordeling en vermindering van hitteproblematiek. Doel is om tot een heldere besluitvorming te komen
Optimal clinical management of children receiving ketogenic parenteral nutrition: a clinical practice guide
AIM To give evidence-based recommendations on the application of ketogenic diet
parenteral nutrition (KD-PN) in emergency situations.
METHOD An international group of experts (n=14) researched the literature and distributed a
survey among 150 expert centers. International accepted guidelines (European Society for
Clinical Nutrition and Metabolism/European Society for Paediatric Gastroenterology
Hepatology and Nutrition and the American Society for Parenteral and Enteral Nutrition) and
handbooks for parenteral nutrition were considered general standards of care.
RESULTS In the literature, we identified 35 reports of patients treated by KD-PN. International
guidelines and handbooks provided some conflicting information. Twenty-four expert teams
from nine countries responded to the survey, reflecting the limited clinical experience.
INTERPRETATION This paper highlights 23 consensus-based recommendations for safe and
effective KD-PN (e.g. diet initiation, calculation, application, monitoring, and evaluation)
based on the best evidence available and expert opinions
Reclassifying historical disasters: from single to multi-hazards
EGU General Assembly 2024, Session NH10.1.Multi-hazard events, characterized by the simultaneous, cascading, or cumulative occurrence of multiple natural hazards, pose a significant threat to human lives and assets. This is primarily due to the cumulative and cascading effects arising from the interplay of various natural hazards across space and time. However, their identification is challenging, which is attributable to the complex nature of natural hazard interactions and the limited availability of multi-hazard observations. This presentation, focused on a recently published article in Science of the Total Environment (https://doi.org/10.1016/j.scitotenv.2023.169120), presents an approach for identifying multi-hazard events during the past 123 years (1900-2023) using the EM-DAT global disaster database. Leveraging the βassociated hazardβ information in EM-DAT, multi-hazard events are detected and assessed in relation to their frequency, impact on human lives and assets, and reporting trends. The interactions between various combinations of natural hazard pairs are explored, reclassifying them into four categories: preconditioned/triggering, multivariate, temporally compounding, and spatially compounding multi-hazard events. The results show, globally, approximately 19% of the 16,535 disasters recorded in EM-DAT can be classified as multi-hazard events. However, the multi-hazard events recorded in EM-DAT are disproportionately responsible for nearly 59% of the estimated global economic losses. Conversely, single hazard events resulted in higher fatalities compared to multi-hazard events. The largest proportion of multi-hazard events are associated with floods, storms, and earthquakes. Landslides emerge as the predominant secondary hazards within multi-hazard pairs, primarily triggered by floods, storms, and earthquakes, with the majority of multi-hazard events exhibiting preconditioned/triggering and multivariate characteristics. There is a higher prevalence of multi-hazard events in Asia and North America, whilst temporal overlaps of multiple hazards predominate in Europe. These results can be used to increase the integration of multi-hazard thinking in risk assessments, emergency management response plans and mitigation policies at both national and international levels
