Isolation, Behavioral Identification, and Pathogenicity Assessment of Entomopathogenic Fungi from a Forest Wood Borer

Forest wood borers (FWB) cause severe tree damage and economic losses worldwide. The release of entomopathogenic fungi (EPF) during the FWB emergence period is considered an acceptable alternative to chemical control. However, EPF resources have been significantly less explored for FWBs, in contrast to agricultural insect pests. This paper presents a protocol for exploring EPF resources from FWBs

Impacts of dams on lowland agriculture in the Mekong River catchment

På den Indokinesiska halvön ligger Mekongflodens avrinningsområde. De senaste årtiondena har Kina, som innehar den nordligaste delen av flodbassängen, startat ett omfattande vattenkraftsprojekt på flodens huvudfåra. Åtta mycket stora dammar är planerade varav tre redan är byggda. Länderna som ligger nedströms från Kina, nämligen Laos, Kambodja och Vietnam har på senare tid också beslutat att bygga

Urban Ecosystem Vulnerability Assessment of Support Climate-Resilient City Development

Climate change poses a threat to cities. Geospatial information and communication technology (Geo-ICT) assisted planning is increasingly being utilised to foster urban sustainability and adaptability to climate change. To fill the theoretical and practical gaps of urban adaptive planning and Geo-ICT implementation, this article presents an urban ecosystem vulnerability assessment approach using in

Accurate quantification of soil organic matter content using VNIR-SWIR spectra : The role of straw and spectrally active materials

Soil organic matter (SOM) is crucial for carbon sequestration and sustainable agriculture, yet traditional quantification methods are challenging to apply at large scales. Hyperspectral technology combined with machine-learning offers promising prospects for rapid quantification. This study explores the impact of using VNIR-SWIR spectra on SOM quantification in regions characterized by distinctive

Mapping soil cadmium content using multi-spectral satellite images and multiple-residual-stacking model : Incorporating information from homologous pollution and spectrally active materials

Soil cadmium (Cd) contamination significantly threatens ecosystems and human health. Traditional geochemical investigation, although accurate, is impractical for wide-area and frequent monitoring applications. Multi-spectral satellite images combined with the homologous pollution information (HPI) and the spectral and content information of soil organic matter (SOMSCI) is an unconventional and pro

Wetland types and soil properties shape microbial communities in permafrost-degraded swamps

Global warming has accelerated permafrost degradation, destabilizing soil organic carbon (SOC) in wetlands. Soil microorganisms play a crucial role in SOC decomposition. Despite increasing studies on soil microorganisms and their associated impacts on SOC decomposition in wetlands, few studies have simultaneously investigated the impacts of soil physical properties and nutrient stoichiometry on so

Global growth and stagnation of nuclear power - A case of diffusion of a new energy technology in a heterogenous system

Reaching the targets of the Paris Agreement requires acceleration of low-carbon energy transitions. At the same time, it is not fully understood why some technologies spread more rapidly and widely than others. This thesis advances our understanding of the diffusion of large-scale low-carbon technologies by bridging technology diffusion studies and political economy of transitions. Through combini

Closing the Plastic Tap — Global Plastic Waste and the Circular Economy. A Multi-Regional Hybrid Input-Output Analysis of Plastic Waste Footprints

Plastic pollution is a cross-national environmental and societal challenge that needs to be addressed from the point of view of global supply chains. The circular economy (CE) has emerged as an alternative paradigm to the traditional “take-make-waste” models of production and consumption to create a closed-loop system so that plastic is trapped in the economy and not in the environment. This resea

COVID-19 and the Freefall of the Stock Market

Background: The novel COVID-19 outbreak has been present for over a year and is a permanent companion impacting daily lives and hurting economics universal. Since the presence of the coronavirus has been directly impacting stock markets and its returns worldwide, an analysis of the impact on the COVID-19 outbreak is inevitable. Therefore, this paper examines the influence of the novel COVID-19 out

Green IS in SMEs

This research is inspired by the concerns of deterioration of the environment by human activities. Small and medium-sized enterprises (SMEs) represent 90% of all businesses in the world. SMEs as organizational level members of societies are responsible for environmental sustainability as other society members for the damages of their business activities to the environment. The current study aims

Behövs det en reform av FN:s Säkerhetsråd?

Säkerhetsrådet ska i enlighet med art. 39 FN-stadgan vidta kollektiva åtgärder för att bevara den internationella freden och säkerheten. Säkerhetsrådet kan inom ramen för detta uppdrag vidta militära och icke-militära åtgärder under stadgans kapitel VII. För att Säkerhetsrådet ska kunna agera krävs att de fem permanenta medlemmarna Frankrike, Kina, Ryssland (Sovjetunionen), Storbritannien och USA

Farnesyl pyrophosphate is an endogenous antagonist to ADP-stimulated P2Y12 receptor-mediated platelet aggregation.

Farnesyl pyrophosphate (FPP) is an intermediate in cholesterol biosynthesis, and it has also been reported to activate platelet LPA (lysophosphatidic acid) receptors. The aim of this study was to investigate the role of extracellular FPP in platelet aggregation. Human platelets were studied with light transmission aggregometry, flow cytometry and [35S]GTPγS binding assays. As shown previously, FPP

Modeling the seasonality of carbon, evapotranspiration and heat processes for cold climate conditions TRITA-LWR LIC 2054. Licentiate Thesis in Land and Water Resources Engineering. KTH Architecture and the Built Environment, Stockholm

The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this
