Pollination by bees is important for food production. Recent concerns about the declines of both domestic and wild bees, calls for measures to promote wild pollinator populations in farmland. However, to be able to efficiently promote and prioritize between measures that benefit pollinators, such as modified land use, agri-environment schemes, or specific conservation measures, it is important to
Quantifying the water exchange between a forest stand and the atmosphere is of major interest for the prediction of future growth conditions and the planning of silvicultural treatments. In the present study, we address (i) the uncertainties of sap flow estimations at the tree level and (ii) the performance of the simulation of stand transpiration. Terrestrial laser scan images (TLS) of a mature b
Materials that are stored or used in damp climates may be subject to mould growth. However, all materials are not equally susceptible to mould growth. For each specific material, there is a critical moisture level. If this is exceeded, there is a risk that mould fungi will develop on the material. In a building, different constructions are exposed to different climatic conditions. To minimise the
Popular Abstract in Swedish Det traditionella jordbruket i nordvästra Europa har gynnat förekomsten av många arter under tusentals år och den snabba övergången till modernt jord- och skogsbruk har lett till försämrade förutsättningar för dessa arter. Både internationellt och nationellt finns strategier för att bevara biologisk mångfald. I Sverige är dessa strategier integrerade i miljömål med ansThis thesis explores the relationship between land-use and floristic diversity over the last three millennia in the uplands of southern Sweden. A quantitative approach based on high-resolution pollen data was applied, using the Landscape Reconstruction Algorithm (LRA), historical maps/aerial photographs, palynological richness and new ways to estimate past evenness at regional and local spatial sc
Freshwater systems are active components of the global carbon cycle and contribute to global CO2 emissions. Freshwater studies in the Arctic are underrepresented, especially regarding lakes and their Dissolved Organic Carbon (DOC) reactivity and composition dynamics. DOC is a main part of DOM (dissolved organic matter), which drives processes central to carbon cycling, influences chemical and biol
Non-fungible tokens (NFTs) are a type of cryptocurrency that consist of unique, non-exchangeable tokens, which are traded on a blockchain. These unique tokens are associated with digital assets such as images, art, videos, or music. With the rapid rise of NFTs’ popularity in 2021, a community established around trading, selling, and collecting of NFTs. This study explored the NFT community at larg
3,5 miljarder år gamla bakterier kan rädda våra vatten från metallutsläpp Långt innan det fanns syre i atmosfären så fanns bakterier som ”andades” svavel. I stället för att andas ut koldioxid andas dessa bakterier ut sulfid, en negativt laddad svaveljon som binder till metaller. På en avfallsanläggning utanför Hässleholm står en testanläggning där man forskar på att minska utsläppen av metaller t
In today's world, it is essential to understand how customer in-store experiences can be successfully transferred to online environments for international jewelry retailers to master their digital transformation. Further, there is an apparent lack of extensive research about the jewelry retailing industry and its customers in academia despite its prominence in the business world. Therefore, th
Rumour refutation is a series of campaigns that the Chinese authorities invest in combating 'the overflow' of network rumours, especially since 2017. These campaigns reflect the Chinese's knowledge of rumour as false and harmful. Among which #PoliceRefuteRumours on social media platform Weibo is one of the most typical forms conducted most explicitly and exposed problematically. Throug
Sustainable development at the local level is greatly impacted by policymaking. In China’s Jingmai Mountain region, the sustainable development policies are centred mostly around the tea industry, due to the social and environmental dynamics surrounding tea in that region. However, considering the complex interlinkages between the tea industry and local environment and society, the policies concer
Traumatic brain injury (TBI) is a common cause of morbidity and mortality in young individuals. Following TBI, the initial injury caused by the head impact is exacerbated by a complex cascade of secondary injury factors leading to increased tissue loss. TBI is an established risk factor for neurodegenerative disorders including Alzheimer disease (AD). In long-term survivors of TBI, increased aggre
Populärvetenskaplig sammanfattning av examensarbete utfört vid institutionen för byggvetenskaper vid LTH i samarbete med Sweco Civil AB. Under vissa förhållanden kan sugkrafter uppstå i jord. Fenomenet är sammankopplat med hur mycket vatten det finns i marken, desto mindre vatten desto högre sugkraft och därmed mindre risk för att t.ex. jordslänter rasar. För att undersöka detta fenomen har finiIn this master´s dissertation I investigated if it is possible to increase the total stability for excavations in clay, if suction is taken into account during the calculations. The work has been performed at, and in cooperation with, Sweco Civil AB as well as the Dept. of Construction Sciences at Faculty of Engineering LTH, Lund University. The objective of this master´s dissertation is to asse
The world today stands at a cross roads when it comes to energy and electrical grids. A large part of the worlds population still lacks access to reliable working electricity 24 hours a day. Much of this is in remote and poor parts of the world. For much of the 20th century large centralized AC grids have been the norm to provide people with electricity. But for remote parts of the world including
With millions of yearly beach visitors in southern California, beach water quality represents an important factor in public health and ocean dependent economy. Fecal indicator bacteria (FIB) in water is much easier to measure than disease causing organisms but correlation exists between the two. For this reason, FIB concentrations are used to measure recreational water quality and related health r
Vietnam is one of the countries in the world that is projected to be most impacted by climate change. Extreme weather events such as storms and floods are predicted to increase with the changing climate. As such, climate change adaptation is crucial, especially for farmers who are relying on vulnerable livelihoods to climate change. This thesis investigates gendered patterns within the province of
Från år 2021 ska alla nybyggnationer i Europa vara nära-nollenergibyggnader. Detta innebär att byggnaders energianvändning bör vara låg och i mycket hög grad tillförs i form från förnybara energikällor som produceras på plats eller i närheten. Syftet med de höga energikraven är att påskynda takten för att skapa ett mer energieffektivt byggande. Den minskade energianvändningen tillsam-mans med en ö
