A review of the current status and development of 5GDHC and characterization of a novel shared energy system

This review presents the status and outlook for shared energy systems (SES) and fifth-generation district heating and cooling (5GDHC). It provides an overview of the technical and functional knowledge encompassing design and development, operational and system architecture, and control and decision support systems of these technologies. The review also presents different tools and models found in

Site characterization for the design of thermoactive geostructures

This paper addresses the topic of site characterization for the design of Shallow Geothermal Energy (SGE) systems, namely of thermoactive geostructures, which are geotechnical structures, such as piles, retaining walls and tunnel linings, also used as heat exchangers as part of closed-loop SGE systems. Such solutions, being increasingly adopted for buildings’ and infrastructures’ heating and/or co

Impacts of stump harvesting on carbon dioxide, methane and nitrous oxide fluxes

During 2010-2013, we investigated the effects of stump harvesting on greenhouse gas (GHG) fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) with the flux-gradient technique at four experimental plots in a hemiboreal forest in Sweden. All plots were clear-cut and soil scarified and two of the plots were additionally stump harvested. The two clear-cut plots served as control plot

Urbanization’s Effects on Problem Solving Abilities : A Meta-Analysis

Cognitive abilities are often assumed to be advantageous in urban habitats, but relatively few studies tested this assumption. In a meta-analysis, we tested whether urban animals have better problem-solving abilities compared to their less urbanized conspecifics. After screening 210 papers we collected by keyword search and forward search, we found 12 studies that compared the ability to solve foo

Extreme Hot Weather Has Stronger Impacts on Avian Reproduction in Forests Than in Cities

Climate change and urbanisation are among the most salient human-induced changes affecting Earth’s biota. Extreme weather events can have high biological impacts and are becoming more frequent recently. In cities, the urban heat island can amplify the intensity and frequency of hot weather events. However, the joint effects of heat events and urban microclimate on wildlife are unclear, as urban po

Double-brooding and annual breeding success of great tits in urban and forest habitats

Urban areas differ from natural habitats in several environmental features that influence the characteristics of animals living there. For example, birds often start breeding seasonally earlier and fledge fewer offspring per brood in cities than in natural habitats. However, longer breeding seasons in cities may increase the frequency of double-brooding in urban compared with nonurban populations,

Patient-Derived Bladder Cancer Organoid Models in Tumor Biology and Drug Testing : A Systematic Review

Bladder cancer is a common and highly heterogeneous malignancy with a relatively poor outcome. Patient-derived tumor organoid cultures have emerged as a preclinical model with improved biomimicity. However, the impact of the different methods being used in the composition and dynamics of the models remains unknown. This study aims to systematically review the literature regarding patient-derived o

Childhood maltreatment and self-hatred as distinguishing characteristics of psychiatric patients with self-harm: A comparison with clinical and healthy controls

Introduction: Deliberate self-harm (DSH) is common in clinical populations. Childhood maltreatment (CM) and attitudes both towards oneself and towards DSH may be of importance for the development of DSH. This study aimed to test whether patients with DSH report more CM, more negative attitudes towards oneself and more positive attitudes towards DSH than a clinical and a healthy comparison group, a

Fighting Covid-19 amidst Civil Conflict: Micro-Level Evidence from Burkina Faso

How does violent conflict affect the spread of Covid-19? In this paper we analyze how violent conflict influences the adoption of preventative measures and infection rate in a very poor, conflict-affected country, Burkina Faso. We use a unique panel of 1,919 households surveyed during the first six months of the Covid-19 pandemic in 2020 and merge these data with indicators of violence at the muniHow does violent conflict affect the spread of Covid-19?
