Under flera års tid har återkommande förhöjda halter mikroorganismer förekommit i havremjöl på en av Lantmännen Cerealias verksamheter i Järna. Detta har lett till ett begränsat användningsområde och ökade kostnader. Syftet med utredningen var att upparbeta en åtgärdsplan för att förbättra hygienstatusen och minska de kostnader som de förhöjda halterna inneburit. Historisk data har granskats, en
The aggregation of proteins into amyloid fibrils via erroneous folding, also known as misfolding, occurs in several diseases. As a consequence, the study of the kinetics and thermodynamics of this process is currently intensely pursued. Here, we study a minimalistic lattice-based model for amyloid formation using Monte Carlo techniques to sample the grand canonical ensemble, where the chemical pot
The Theory of Characteristic Modes (TCM) provides an alternative means of antenna synthesis in compact mobile handsets by taking into account the chassis. This makes it possible to create dual-element Multiple-Input Multiple-Output (MIMO) antennas in mobile handsets with very little coupling and correlation between the two antennas. But apart from the antennas, modern mobile phones are each equipp
Thymidine kinase 1 from tomato (ToTK1) is a newly discovered deoxyribonucleoside kinase (dNK) that has been subject to study due to its in vitro and in vivo properties making it an interesting suicide gene candidate for the treatment of brain tumors. The ToTK1 phosphorylates the nucleoside analogue 3-azido-2,3-dideoxythymidine (azidothymidine, AZT) equally well as its natural substrate thymidine (
In the present study, the enzyme thymidine kinase 1 from tomato (ToTK1) was expressed in E.coli and purified to near homogeneity by means of affinity chromatography. However, purified ToTK1 of bacterial origin displayed no substantial catalytic activity. Expression was also attempted in insect cells using the baculovirus expression vector system (BEVS). Significant TK activities were detected in t
The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for
Purpose: The aim of this study was to investigate a new methodology for brachytherapy of oesophageal cancer using magnetic resonance (MR) imaging for treatment planning. That includes finding a suitable oesophageal applicator that can be visualised on MR images and to create dose and fraction schedule that should be used brachytherapy treatments. Material and Methods: A total of six patients were
Larm och oljud är en naturlig del av arbetsmiljön på en intensivvårdsavdelning. Störande ljud kan leda till stress och sömnbrist hos patienter. Kunskap hos personal om vad som stör innebär möjligheter till reducering av störningar. Syftet med studien var att mäta frekvensen av potentiella störningsfaktorer avseende ljud från utvald medicinsk apparatur och utrustning för patienter på intensivvårdss
Smittspridning av vårdrelaterade infektioner belastar samhället med en kostnad på miljontals kronor varje år till följd av utökat vårdbehov inom sjukvården. Utöver samhällskostnaderna är det personliga lidandet stort för drabbade patienter och deras anhöriga och varje år avlider ungefär 1 500 patienter av en vårdrelaterad direkt eller indirekt smitta. Enligt Lagen om yrkesverksamhet på hälso- och
Våld i hemmet är ett universellt förekommande problem som framförallt drabbar kvinnor. Studier visar på hög prevalens av våld där kvinnor misshandlats av sin partner. Våldsutsatta kvinnor söker sig ofta till hälso- och sjukvården, vilket gör sjuksköterskor och barnmorskor till viktiga aktörer i arbetet mot våld. Trots den höga förekomsten av våld upptäcker sjuksköterskor och barnmorskor få fall av
Vanligast av de vårdrelaterade skadorna är infektioner, med urinvägsinfektion som en av de mest frekventa. Detta medför extra kostnader för samhället men framförallt mer lidande och längre vårdtid för patienten. År 2008 införde Sveriges kommuner och landsting ett åtgärdsprogram i avsikt att minska de kateterrelaterade urinvägsinfektionerna. Syftet med studien var att undersöka om riktlinjerna från
Transportation equity is vital for the fulfillment of citizens’ activities. To make better decisions for transportation planning, it is appropriate to have a method to evaluate each mode and assign an equity score to it. This paper aims to propose a method to assess the level of equity using different transportation modes in each zone of a city. Here, the equity level takes into account on one sid
We study the long-time behavior of solutions to quasilinear doubly degenerate parabolic problems of fourth order. The equations model, for instance, the dynamic behavior of a non-Newtonian thin-film flow on a flat impermeable bottom and with zero contact angle. We consider a shear-rate dependent fluid the rheology of which is described by a constitutive power law or Ellis law for the fluid viscosi
The COVID-19 pandemic is a crisis that is "creeping" in its onset and "slow-burning" in its duration. It is characterized by extreme uncertainty, ambiguity, and complexity, presenting an unprecedented need for response across sectors and political-administrative levels. While there has been an explosion of research papers into the national strategies for handling the pandemic, empirical publicatio
Introduction. The cure rate of early stage Hodgkin's lymphoma (HL) is excellent; investigating the late effects of treatment is thus important. Esophageal toxicity is a known side effect in patients receiving radiotherapy (RT) to the mediastinum, although little is known of this in HL survivors. This study investigates the dose to the esophagus in the treatment of early stage HL using different RT
In this paper we propose a shared regression network to jointly estimate the pose of multiple objects, replacing multiple object-specific solutions. We demonstrate that this shared network can outperform other similar approaches that rely on multiple object-specific models by evaluating it on the TLESS dataset using the VSD (Visible Surface Discrepancy). Our approach offers a less complex solution
It has been shown that ultra-high frequency (UHF) ultrasound applied to the external bowel wall can delineate the histo-anatomic layers in detail and distinguish normal bowel from aganglionosis. This would potentially reduce or lessen the need for biopsies that are currently mandatory for the diagnosis of Hirschsprung’s disease. However, to our knowledge, no suitable rectal probes for such a use a
