Introduktion av lågvibrerande maskiner vid arbetsplatser med hög vibrationsexponering : framgångsfaktorer för efterfrågan och användning

Exponering för vibrationer genom användning av handhållna maskiner i arbetet kan ge vibrationsskador i händerna. Dessa skador kan ofta vara förödande för den drabbades möjligheter att utföra sitt arbete, innebära ett stort personligt lidande samt stora samhälleliga kostnader då det inte sällan innebär behov av omplacering.Denna rapport är en del av projektet Noll Vibrationsskador, vilket har haft

Parametric Model-Based 2-D Autofocus Approach for General BiSAR Filtered Backprojection Imagery

The filtered backprojection (FBP) algorithm is viewed as a preferred candidate for general bistatic synthetic aperture radar (BiSAR) imaging since it does not pose any restrictions on SAR configurations or flight paths. However, high-efficient autofocus methods such as phase gradient autofocus (PGA) or Mapdrift (MD) cannot be effectively integrated with the FBP algorithm due to the unknown propert

Proteomic analysis of food allergens

Food allergies are a growing health problem that generate high costs for health systems. Food allergies have a prevalence of 6-8% in children and 2-3% in adults, which is increasing in the last 10 years due to industrialization. The wide variety of ingredients containing food allergens, in combination with the high number of product formulations and processing methods to produce food makes allerge

Is there an association between consumers’ personality traits and the sensory characteristics they look for in wine?

This study investigates the link between the personality profiles and socio-demographic characteristics of wine consumers and the sensory characteristics of the wines they prefer. This was measured in terms of a self-reported list of the wines they like and buy. The 1176 Italian adults who participated were asked to complete an online form. Information was collected regarding certain socio-demogra

Individual’s risk attitudes in sub-Saharan Africa : Determinants and reliability of self-reported risk in Burkina Faso

Understanding individual risk taking is an important topic in Africa, as access to financial institutions and social security is scarce, and where markets and government policies largely fail to understand investment decisions of poor households. Data on risk attitudes in Africa is limited and the available data collected might not be reliable. We investigate the determinants of risk attitudes in Understanding individual risk taking is an important topic in Africa, as access to financial institutions and social security is scarce, and where markets and government policies largely fail to understand investment decisions of poor households.

Arcs on speedskating straightaways : forces, energy and angular momentum

The 10 000 m speedskating event during the 2022 winter Olympics brought a new world record at 12 min and 30.74 s. In a document released after the competitions, the gold medalist Nils van der Poel describes his technique, including a focus on horizontal forces and a rapid sideways motion in connection with stride changes on the straight sections of the track (the ‘straightaways’). Based on a video

Waveform optimization with SINR criteria for FDA radar in the presence of signal-dependent mainlobe interference

In this paper, we focus on the design of the transmit waveforms of a frequency diverse array (FDA) in order to improve the output signal-to-interference-plus-noise ratio (SINR) in the presence of signal-dependent mainlobe interference. Since the classical multi-carrier matched filtering-based FDA receiver cannot effectively utilize the waveform diversity of FDA, a novel FDA receiver framework base

Alkali Metal Cations as Charge-Transfer Bridge for Polarization Promoted Solar-to-H2 Conversion

Utilization of spontaneous polarization electric field of ferroelectric materials to realize the spatial separation and fast transfer of photogenerated charges has been regarded as a promising strategy to fabricate highly efficient photocatalysts. Herein, a novel heterostructure is constructed by coupling potassium poly(heptazine imide) (K-PHI) with ferroelectric BaxSr1-xTiO3 (BxST) through a faci

Influences of bus traffic loading on asphalt concrete rutting

Permanent deformation is the primary failure mode for the asphalt concrete (AC) pavement in urban environment. It is mainly caused by a combination of heavy traffic load, low vehicle speed and channelised traffic. A rut prediction model would therefore be a valuable tool for planning maintenance scheduling and selecting an appropriate asphalt material. This study uses the PEDRO (Permanent deformat

FIRE : A framework for integrating human rights and gender equality in disaster risk reduction and climate change adaptation

This article introduces the Framework for Integrating Rights and Equality (FIRE): a transdisciplinary framework that builds synergies between human rights-based (HRBA) and gender equality approaches to disaster risk reduction (DRR) and climate change adaptation (CCA). It describes how FIRE has been developed, tested and refined over the course of a five-year regional learning and technical coopera

Nanofluidic analytical system integrated with nanochannel open/close valves for enzyme-linked immunosorbent assay

There have been significant advances in the field of nanofluidics, and novel technologies such as single-cell analysis have been demonstrated. Despite the evident advantages of nanofluidics, fluid control in nanochannels for complicated analyses is extremely difficult because the fluids are currently manipulated by maintaining the balance of driving pressure. To address this issue, the use of valv

Clinical and epidemiological Studies in ANCA-associated vasculitis

Objectives:This thesis aims to provide an overview of the epidemiology of AAV in southern Sweden, to evaluate different classification criteria in AAV. In addition we study if infection is a risk factor for later development of AAV comparing patients with AAV with a matched population cohort and to examine the occurrence of severe infections as an outcome in AAV. Methods:All adult patients diagnos
