Buller är erkänt som det näst största miljörelaterade hälsoproblemet enligt WHO \cite{WHO} och det är därför är det viktigt att skapa goda metoder för att undersöka hur fastigheter påverkas av buller och vibrationer. Detta examensarebete har fokuserat på att undersöka buller och vibrationer i en flervåningsbyggnad orsakat av tågtrafik.One of the modern cities environment issues is noise and vibration created by train traffic, especially since cities today strive towards being more dense. Urbanization leads to new areas built with pre existing railway tracks. This puts a lot of pressure on the structures built on those areas regarding vibrations. Heavy concrete buildings are more resilient against vibrations than light-weight st

Den här rapporten undersöker samt jämför det möjliga användandet av olika tillverkningsmetoder i produktionen av varianthålade plattor vid Alfa Lavals produktion i Lund. De tre metoderna är stansning med excenterpressar, abrasiv vattenskärning och laserskärning, där de två förstnämnda används i Alfa Lavals produktion i dagsläget. Syftet med projektet är att förkorta ledtider, genom att hitta en meThis report investigates and compares the possible use of different manufacturing methods in production of odd-holed plates at Alfa Laval’s site in Lund. The three methods are punching with eccentric presses, abrasive water jet cutting and laser cutting, with the first two being used currently at Alfa Laval. The aim of the project is to shorten the lead times, by finding a method that is efficient

Better estimates of the net exchange of CO(2) between the atmosphere and the terrestrial biosphere are urgently needed to improve predictions of future CO(2) levels in the atmosphere. The carbon cycle data assimilation system (CCDAS) offers the capability of inversion, while it is at the same time based on a process model that can be used independent of observational data. CCDAS allows the assimil

Abstract In developed economies industry was once the backbone of the economy and was seen as the machinery behind economic growth. During the past decades, industry’s importance has been diminishing in advanced economies. The trend has been stronger in some countries than in others but seems rather consistent over time. Furthermore the financial sector has enjoyed vast growth since the 1980’s. In

Purpose: The purpose of the thesis is to investigate whether the future development of the Digital Home creates incentives for Sony Ericsson to initiate an Open Source based platform strategy. Issues: The main issues presented: To create future scenarios of the Digital Home environment and describe its ecosystem of consumer electronics and mobile phones. To investigate the competitive advantage fo

Organic carbon burial in lake sediments plays an important role in the global carbon cycle, and is heavily affected by the terrestrial organic matter input. However, few studies have focused on long-term changes in terrestrial organic matter input to lakes in response to land-use changes. The aim of this study was to assess variations in sedimentary terrestrial organic matter over the last 1000 ye

BACKGROUND: It is still unclear to what extent the most common animal models of pain and analgesia, based on indirect measures such as nocifensive behaviours, provide valid measures of pain perception.METHODS: To address this issue, we developed a novel animal model comprising a more direct readout via chronically (>1 month) implanted multichannel electrodes (MCE) in rat primary somatosensory cort

Major intrinsic proteins (MIPs) are proteins that allow the passive transfer of uncharged molecules through a membrane. They have many subfamilies the least understood of which is “X” intrinsic proteins (XIPs). The X illustrates that they are functionally uncharacterized. XIPs have previously been shown to facilitate the transport of boric acid, hydrogen peroxide, urea and glycerol across the memb

In recent years, the empirical literature on cross-national unions—marriages between migrants and members of the majority population—has experienced a shift in focus, with an increasing number of studies examining assortative mating patterns within these unions. This shift marks a significant development, indicating that the classic assimilation theory is no longer considered the sole explanation

Recent advances in the investigation of the relationship between language and cognition have demonstrated that speakers of English categorise objects based on their common shape, while speakers of Yucatec and Japanese categorise objects based on their common material (Lucy & Gaskins 2003; Imai & Mazuka 2003). The current study extends that investigation to the domain of bilingualism. Resul

Measurements of anisotropic flow coefficients (vn) and their cross-correlations using two- and multiparticle cumulant methods are reported in collisions of pp at s=13 TeV, p-Pb at a center-of-mass energy per nucleon pair sNN=5.02 TeV, Xe-Xe at sNN=5.44 TeV, and Pb-Pb at sNN=5.02 TeV recorded with the ALICE detector. The multiplicity dependence of vn is studied in a very wide range from 20 to 3000

The World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) coordinates high-quality atmospheric greenhouse gas observations globally and provides these observations through the WMO World Data Centre for Greenhouse Gases (WDCGG) supported by Japan Meteorological Agency. The WDCGG and the National Oceanic and Atmospheric Administration (NOAA) analyse these measurements using different

This chapter sets the stage for the volume. Sustainable consumption has long been on the global agenda, yet prevailing consumption patterns continue to drive climate change, resource depletion and biodiversity loss. One of the key barriers is the persistence of myths – narratives that render unsustainable practices normal, desirable or even virtuous. The chapter situates myths historically, tracin
