The presence of genes encoding organellar proteins in different cellular compartments necessitates a tight coordination of expression by the different genomes of the eukaryotic cell. This coordination of gene expression is achieved by organelle-to-nucleus communication. Stress-induced perturbations of the tetrapyrrole pathway trigger large changes in nuclear gene expression. In order to investigat

Antisera produced against peptides deduced from potato nda1 and ndb1, homologues of yeast genes for mitochondrial rotenone-insensitive NADH dehydrogenases, recognise respective proteins upon expression in Escherichiacoli. In western blots of potato (Solanum tuberosum L.) mitochondrial proteins, the NDB and NDA antibodies specifically detect polypeptides of 61 and 48 kDa, respectively. The proteins

Popular Abstract in Swedish Två riskanalysmetoder presenteras med vilka risken för personskador till följd av brand kan uppskattas. Metoderna, standard QRA (Quantitative Risk Analysis) och utökad QRA skiljer sig åt varigenom osäkerheter i ingående variabler behandlas. Osäkerheter ingår i princip i alla variabler och måste behandlas på något rationellt sätt. Standard QRA-metoden förutsätter att en Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. The standard QRA does not consider the uncertainties in the variables and must be complemented by a sensitivity analysis or an uncertainty analysis.

Purpose: We tested the biocompatibility of nitinol, a nickel titanium alloy, and stainless steel (SS) as bladder implant materials. Materials and Methods: Rats received a nitinol implant, an SS implant or were sham controls. Two, 3, 6 and 8 weeks following implantation 24-hour voiding behavior studies were per-formed to investigate bladder irritation. All animals were sacrificed 8 weeks after impl

OBJECTIVES: To investigate renal artery patency and renal function after deployment of aortic stents covering the orifices of renal arteries. DESIGN: Prospective open animal study. SETTING: Department of Experimental Surgery at a university hospital. MATERIALS: Twenty-three pigs were used. METHODS: Ten pigs were observed for 1 h after graft-anchoring aortic stents, Gianturco (5) and Palmaz (5), we

BACKGROUND: High-resolution microarray-based comparative genomic hybridization (CGH) techniques have successfully been applied to study copy number imbalances in a number of settings such as the analysis of cancer genomes. For normalization of array-CGH data, methods initially developed for gene expression microarray analysis have, in general, been directly adopted and used. However, these methods

Background: Two contradictory hypotheses have been proposed to explain the relationship between allergic conditions and malignancies, the immune surveillance hypothesis and the antigenic stimulation hypothesis. The former advocates that allergic conditions may be protective against development of cancer, whereas the latter proposes an increased risk. This relationship has been studied in several c

This essay concerns the legislation and legal procedures concerning the crime “rape”. We focus on rapes committed by young offenders and where young victims (girls) are involved. Media often presents a picture that raped girls don’t get a fair trial because she comes out as a bad looking girl in court. Our purpose has been to investigate and analyse rape from a historical and legal perspective and

The purpose of this essay was to describe how it is possible for a treatment centre to create favourable conditions for a successful moving out, and what support is required after moving out to maintain a positive way of life. My central questions were: what does a person need to be able to develop/change and how can you work with this at the treatment centre? What are the required conditions for

The threat of change and the loss it can incur creates the need to preserve a detailed version of the past. Elizabeth Gaskell's Cranford can be interpreted as a piece looking backwards as a means of looking forward; acknowledging and commemorating the existence of a rich and detailed past allows for the closing of its chapters, and thus eventual movement into a new future. In this paper I will

Purpose: To map out how an industrial company can manage CSR efforts within the supply chain, balancing stakeholder demands with their own strategic approach. The study also investigated how a company can handle issues such as sourcing of politically sensitive materials, although not part of their CSR focus. Methodology: A single-case study where semi-structured interviews built the understandin

This paper investigates the correlation between Sweden's municipal equalization system and economic growth and efficiency for the years 2005 to 2022. This paper uses panel data for all 290 municipalities and a fixed effects model to study the two main parts of Sweden's municipal equalization system: the income equalization system and the cost equalization system. This paper examines multip

This study aims to investigate how social media trends affect international trade through a study on the relationship between the global matcha tea trend and Japanese green tea exports. The study is performed in two steps, due to limitations in social media data access. Firstly, a time-series regression is used to analyse the relationship between global TikTok views and Google search intensity for

Bakgrund: Sömn är en grundläggande förutsättning för människans generella hälsa och ett gott sömnmönster är grundläggande för att individer ska kunna utföra sina dagliga aktiviteter. Detta examensarbete utgår från de beteendemässiga aspekterna av människans sömn. Sömnmönstret definieras utifrån fem parametrar: sömnlatens, antal nattliga uppvaknanden, totalt antal sömntimmar under natten, total sömA good sleep pattern is fundamental for an individual to be able to carry out their daily activities. This thesis aims to examine the behavioral aspects of human sleep patterns. The term sleep pattern is defined by five parameters: sleep latency, nocturnal awakenings, sleep duration, sleep quality and circadian rhythm. Our aim was to investigate how the sleep patterns of university students at thr

Detta examensarbete utfört på uppdrag av och i samarbete med Vossloh Nordic Switch Systems AB i syfte att ta fram ett pressverktyg för montering av fjäderbefästningar (s.k. pandrolfjädrar) vilka används vid installation av järnvägsväxlar. Det verktyg som huvudsakligen används idag har inte kunnat brukas till hela produktportfolion av växlar på grund av verktygets storlek som inte tillåter åtkomst This master thesis work was carried out on behalf of and in collaboration with Vossloh Nordic Switch Systems AB with the aim of developing a pressing tool for the assembly of spring fasteners (so-called Pandrol e-clips) used in the installation of railway switches. The tool primarily used today has not been able to be used for the entire product portfolio of switches due to the tool’s size, which

Detta examensarbete presenterar resultatet av en utredning av ihopspänningen av en packningsförsedd plattvärmeväxlare. Projektets huvudfokus var att hitta en ny metod för att spänna ihop en packningsförsedd värmeväxlare some är mer exakt än den nuvarande metoden. Detta åstadkomms genom att ta hänsyn till tillverkningstoleranserna av de ingående delarna. Andra faktorer som antalet kanalplattor, matThis thesis presents the results of an investigation of the tightening function of a gasketed plate heat exchanger (GPHE). The main focus of the project has been to find a new method for tightening a GPHE that is more accurate than the current method. This is achieved by factoring in manufacturing tolerances of the ingoing parts. Other factors such as the number of channel plates, channel plate ma

Arbetsmotivation är ett välutforskat ämne inom arbets- och organisationsforskning, och går att betrakta ur ett flertal olika perspektiv (Tremblay et al., 2009). Med hjälp av självbestämmandeteorin (Deci & Ryan, 1985) syftade denna kvantitativa studie till att undersöka potentiella skillnader mellan inre och yttre motivation i förhållande till kreativitet på arbetsplatsen, samt om dessa skillnaWork motivation is a well-researched topic in work and organizational research, and can be viewed from several different perspectives (Tremblay et al., 2009). Using self-determination theory (Deci & Ryan, 1985) this quantitative study aimed to investigate potential differences between intrinsic and extrinsic motivation in relation to creativity in the workplace, and whether these differences v
