Järnvägsindustrin spelar en avgörande roll på den globala marknaden för godstransporter och passagerarmobilitet, och ger ett effektivt och lågemitterande transportmedel. För att konkurrera med andra transportmedel måste järnvägen dock förbättra sin tillförlitlighet. Frekventa inspektions- och underhållsarbeten är avgörande för att säkerställa säkerheten och effektiviteten i järnvägsverksamheten. DThe railway industry plays a crucial role in the global freight transport and passenger mobility market, providing an efficient and low-emitting mode of transportation. However, to compete with other modes of transportation, the railway must improve its reliability. Frequent inspection and maintenance work are essential for ensuring the reliability, safety, and efficiency of railway operations. Th

In October 2022, the European Commission announced a legislative proposal to make instant payments in euro available to all citizens with a bank account in the EU and EEA countries. When adopting new payment technologies, it can be challenging to balance security and convenience. Consideration must be given to whether compromised security is an unavoidable effect of instant payments or if both obj

A sediment record obtained from a small lake in Warming Land, northern Greenland was subjected to biostratigraphic and geochemical analyses to investigate environmental and climatic changes during the last c. 2300 years. Macrofossil analysis, encompassing both vegetation and fauna, was applied to assess the ecological dynamics of the lake and its catchment. Geochemical proxies in the form of total

This Master thesis is investigating how communities of practice can enhance knowledge sharing in a context of improving a harmonized Enterprise Resource Planning (ERP) system used in supply chain. A student from the faculty of production and materials engineering at Lund university (LTH) collaborated with the Global Trinity organization from Alfa Laval (Lund, Sweden) to answer the research que

Syfte. Studien syftade till att undersöka om logopeder som inte har svenska som förstaspråk upplever mer språkångest jämfört med dem som har svenska som förstaspråk när de använder sin expressiva språkliga förmåga på svenska. Ett ytterligare syfte var att undersöka om logopeder som inte har svenska som förstaspråk upplever ett allmänt sämre välbefinnande jämfört med de som har svenska som förstaspPurpose. The purpose of the study was to investigate whether speech-language pathologists (SLP) who are not native speakers of Swedish experience more language anxiety compared to native speakers of Swedish when using their expressive language skills in Swedish. Furthermore, a secondary aim was to investigate whether non-native Swedish speakers experience a generally poorer well-being compared to

Black Carbon är resultatet av ofullständig förbränning av fossila bränslen och biomassa. Partiklarna blir luftburna i samband med förbränning och sprids över hela jorden. Utsläpp och spridning av BC är problematiskt, eftersom partiklarna har stor påverkan på människors hälsa och miljön. Metoder för utvinning och kvantifiering av BC ur olika material finns. I studien används en variant av CTO-375-mBlack Carbon is the product of incomplete combustion of fossil fuels and biomass. The particles become airborne during combustion and are effectively distributed all around the world. The release and distribution of BC is of concern because of the effect it has on our health and the environment. To be able to separate BC from sediment and quantify the amount, different methods have been developed.

In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by l

Dysexecutive Questionniare (DEX) är ett av de mest vanligt förekommande skattningsformulären som mäter exekutivt fungerande i vardagen, och administreras oftast till patienter med förvärvad hjärnskada. Eftersom individer med förvärvad hjärnskada riskerar att lida av nedsatt självmedvetenhet av brister i exekutiva funktioner, är skalan tillgänglig både som självskattning och informantskattning. DenThe Dysexecutive Questionnaire (DEX) is one of the most commonly used rating scales of executive functioning in daily life and is most frequently administered to patients with acquired brain injury (ABI). Because individuals with ABI are at risk of suffering from impaired self-awareness of executive function deficits, the scale is available both as a self-assessment and in an independent-rating ve

Den här uppsatsen har behandlat en ny variant av haloeffekten som vi benämner personlighetsbaserad kompetenshalo. Den handlar om att personlighetsbeskrivning påverkar bedömning av kompetens. Studiens frågeställning var om det fanns någon skillnad i den personlighetsbaserade kompetenshalons styrka beroende på om individen som skattas tillhör en ingrupp eller ej, där grupptillhörighet kategoriseras This thesis examined a new variant of the halo effect, which we call personality-based competence halo. It concerns personality description influencing the judgment of competence. The study investigated whether there was any difference in the strength of the personality-based competence halo depending on whether the individual being assessed belongs to an in- or outgroup, whereby age was the varia

The term “Young-Old” was introduced in 1974 by Bernice Neugarten, who further subdivided the elderly population. This term also corresponds to the third stage of the life cycle of childhood, adulthood, “Young-Old” and “Old-Old”. According to this quadripartite division, “Young-Old” can be called the “Third Age.” This group is the new and rapidly expanding elderly population of healthy and independ

Purpose: The purpose is to provide a nuanced understanding of organisational cultural differences, obstacles associated with the human integration process and management strategies to overcome them. Theoretical Framework: Organisational cultural differences are treated as stemming largely from the organisation’s task environment, influenced by industry and function. Human integration is the proce

Syftet med vår studie var att se vilka eventuella samband det finns mellan boendemiljö och psykologiskt välbefinnande för individer som arbetar hemifrån. I dagens flexibla arbetsliv är arbete hemifrån ett vanligt inslag, vilket gör ämnet aktuellt och intressant att undersöka. Vi valde att genomföra en kvantitativ korrelationsstudie. Som datainsamlingsmetod använde vi en digital enkät. 100 arbetst

The number of diplomatic actors that use social media platforms to communicate with the publics has increased in the past years. Yet, these communicative approaches are still poorly researched. Moreover, the few studies from diplomacy and the ones from communication that explore two-way communication on social media present contradictions. If scholars from diplomacy present dialogue as a taken for

This bachelor's thesis seeks to investigate how the physical working environments of Born Global firms affect innovation, and more specifically analyze which physical attributes in the working environment nudge towards innovation. Born Globals are characterized as young firms with the ambition to gain global presence near founding. Since Born Global firms are at the beginning of their developm

I Socialstyrelsens rapport ”Vårdnadsöverflyttning i samband med våld i familjen” som publicerades 2013 framkom att det i många fall tog lång tid för vårdnaden att flyttas från en förälder som dödat den andra föräldern. Detta föranledde regeringen att utreda möjliga lösningar för att vårdnadsöverflyttningen i sådana fall skulle kunna göras snabbare, och resulterade i införandet av 6 kap 10 d § föräThe National Board of Health and Welfare presented a report in 2013 regarding custody transfers relating to violence in the family. The report showed that it took a long time for a custody transfer to occur in cases when a parent had killed the other parent. This led the government to investigate possible solutions to make such custody transfers happen faster, which resulted in chapter 6 section 1

Values are a crucial aspect of human–nature relationships, and they play important roles in policies on land use and environmental management. However, our current decision-making systems tend to take inadequate account of the diversity of values associated with human relationships with nature. Instrumental, monetary values dominate the political systems following the Western neoliberal hegemony.

Using silicon nanowire (NW) arrays for solar energy conversion has gained special interest in the past years especially for their strong light interaction. The application in photocatalysis, however, requires an additional layer of protection for the silicon surface. To that end, silicon NWs with titanium nitride (TiN) coating, which exhibit a much stronger absorption than their uncoated counterpa

I denna uppsats studerar vi en matematisk modell av vattenvågor över djupt vatten. I synnerhet studerar vi vågor som färdas med konstant hastighet i en horisontell riktning och är likformiga i den vinkelräta horisontella riktningen. På grund av den matematiska svårigheten med den allmänna modellen är det vanligt att utgå från förenklade versioner av problemet. I denna uppsats, gör vi antaganden omIn a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touchin
