Influence of foundation type and soil stratification on ground vibration - A parameter study

Vibration of machinery and construction work are major sources of noise and vibration pollution in the urban environment. The frequencies dominating the vibration, and the distances over which it spreads via the ground, depend on the source. However, soil stratification and foundation type have a significant influence. Thus, in order to achieve fair accuracy in the prediction of ground vibration c

Numerical modelling of ground vibration caused by elevated high-speed railway lines considering structure-soil-structure interaction

Construction of high-speed railway lines has been an increasing trend in recent years. Countries like Denmark and Sweden plan to expand and upgrade their railways to accommodate high-speed traffic. To benefit from the full potential of the reduced commuting times, these lines must pass through densely populated urban areas with the collateral effect of increased noise and vibrations levels. This p

Motivating factors for return to work.

BACKGROUND AND PURPOSE: A new concept to increase return to work for patients listed as sick with chronic musculoskeletal pain has been used at a rehabilitation centre in Luleå, Sweden. The programme includes work for three days a week and intensive rehabilitation for two days a week, for 12 weeks, as a combination of 'on the job' training and rehabilitation after a period off work sick. The rehab

Strategy for predicting railway-induced vibrations in buildings

Urban densification is a way of accommodating population growth. Land adjacent to railways is used for constructing residences and other buildings, and new tramway systems are planned. Under these circumstances, nearby buildings will be exposed to vibrations and noise that may become a nuisance for the residents. It is necessary, even at an early stage of planning, to assess the extent of the vibr

Child Rights, Classroom and School Management : Change Projects from the International Training Programme Batch 13 - 2010b

In 2003 Lund University Commissioned Education was given the task, after publictender, to create and administrate a programme on “Child Rights, Classroom andSchool Management” following the provisions and principles contained in the UNConvention on the Rights of the Child (CRC), Sida’s development policy on Education and other internationally ratified instruments in the areas of child rights and e

Framework for research on improved life quality

The Sound Environment Center at Lund University has for over ten years hosted interdisciplinary research on sound environment issues promoting an exchange of ideas between researchers through research projects, interdisciplinary symposiums and publications. The center aims at developing a holistic view to a field that is scientifically fragmented. Ranging from acoustics, noise abatement and sounds

Comparisons of various approaches to low frequency in-situ measurements and corresponding models

New recommendations for environmental noise levels have been issued in Sweden. The permissible levels at facades of new buildings have been increased, which has resulted in a risk for higher indoor low frequency noise levels, since the recommended indoor levels are A-weighted. The additional Swedish low frequency third octave band requirements might be violated. Therefore, there is a need for revi

Child Rights, Classroom and School Management : Change Projects from the International Training Programme Batch 14 - 2011a

Lund University has offered the Sida-financed International Training Programme on Child Rights, Classroom and School Management since 2003. The programme targets those in a position from which they can initiate processes of change in the education sector in their countries. During the programme all participating teams initiate a change project in their respective countries aiming at the realizatio

Motion control system of MAX IV Laboratory soft x-ray beamlines

At the MAX IV Laboratory, five new soft x-ray beamlines are under development. The first is Species and it will be used to develop and set the standard of the control system, which will be common across the facility. All motion axes at MAX IV will be motorized using stepper motors steered by the IcePAP motion controller and a mixture of absolute and incremental encoders following a predefined coor

Mutation of the key residue for extraribosomal function of ribosomal protein S19 cause increased grooming behaviors in mice

Ribosomal protein S19 (RP S19) possesses ribosomal function as RP S19 monomer and extraribosomal function as cross-linked RP S19 oligomers which function as a ligand of the complement 5a (C5a) receptor (CD88). We have generated a Gln137Glu-RP S19 knock-in (KI) mouse, which is shown to possess the weakened extraribosomal function of RP S19. Because whether the extraribosomal function of RP S19 has

The multi-bend achromat storage rings

Not very long ago, the 3rd generation storage ring technology was judged as mature. Most of the 3rd generation storage rings used the Double-Bend Achromat (DBA) or Triple-Bend Achromat (TBA) concepts. It was however a well-known fact that increasing the number of magnet cells in the rings is a powerful way of decreasing the electron beam emittance and thus the source brilliance, but at the penalty

Deep sequencing reveals global patterns of mRNA recruitment during translation initiation

In this work, we developed a method to systematically study the sequence preference of mRNAs during translation initiation. Traditionally, the dynamic process of translation initiation has been studied at the single molecule level with limited sequencing possibility. Using deep sequencing techniques, we identified the sequence preference at different stages of the initiation complexes. Our results

Stretching the boundaries : Tanzanian pharmacy workers' views and experiences of providing STI services for men who have sex with men

Objective: To explore the views and experiences of providing assistance and treatment of sexually transmitted infections to same-sex practicing male clients among service providers at pharmacies and drugstores in Dar es Salaam, Tanzania. Previous research suggests that sexually transmitted infections are an increasing concern for this population. Due to stigma and discrimination, men who have sex

Computational modelling of wear – application to structured surfaces of elastoplastic tools

Sheet bulk metal forming processes are applied in order to produce tailored workpieces at high quality. Thereby, effort is made to optimise frictional and wear behaviour by designing the structures of the contact surfaces. Numerical process analysis can evoke a deeper under-standing of the functionality of such surface structures. In this contribution, a finite element framework for the simulation

Optimal Segmentation for Piecewise RF Power Amplifier Models

Accurate modeling of an RF power amplifier and/or its inverse is the core element of every digital predistortion system. An interesting alternative to the family of classic polynomial models are piecewise models, which divide the magnitude range into segments and define gain/phase-distortion through complex-valued functions on a per-segment basis. Naturally, the question arises whether a well-chos

The Role of the State in Employment and Welfare Regulation: Sweden in the European Context

This article examines the changing role of the Swedish state in employmentand welfare regulation in an environment that has become more market driven,commodified, and Europeanized. It begins with a theoretical reflection on the role of the state in capitalist development and a review of the recent debate on the spatiality of state regulation: the state as employer, redistributor, and arbiter, and

Update of EULAR recommendations for the treatment of systemic sclerosis

The aim was to update the 2009 European League against Rheumatism (EULAR) recommendations for the treatment of systemic sclerosis (SSc), with attention to new therapeutic questions. Update of the previous treatment recommendations was performed according to EULAR standard operating procedures. The task force consisted of 32 SSc clinical experts from Europe and the USA, 2 patients nominated by the
