Lumazine Synthase forms pentamers, C5 in some organism and icodahedra, Ih in other. The aim of this project is to investigate which evolutionary steps could have led the pentamers to assembly into icosahedral capsids. Therefore prevoius work has been performed to reconstruct ancestral sequences for the pentameric and icosahedral forms of Lumazine Synthase. The icosahedral sequence had been express
To allow further device scalability within the data storage industry there needs to be continued research of new technologies. One promising technology is the Magnetic Random Access Memory (MRAM), based on magnetoresistive elements, which is non-volatile; consume low power and have fast read and write operations. To make the technology scalable, the bit (the smallest element in the MRAM) needs to
Denaturation mapping is a powerful and fast method for optically analyzing DNA molecules.It can be used to characterize DNA molecules on a scale of a few hundred base pairs which is sufficient for applications. Denaturation mapping requires a sufficiently high optical resolution of the imaging system used, which typically translates to an expensive, bulky microscope. For point-of-care testing or u
This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this purpose, single acrylate, dual acrylate, copper and aluminum coated bers are analyzed theoretically and experimentally regarding the thermal sensitivity of their optical path length. Experimental results w
The field of particle physics is ever evolving. With the recent advent of the Large Hadron Collider (LHC) it is possible that the long sought for Higgs boson is detected. While this is not certain even if it is found it is likely that it will need more precise methods of investigation. For this and other reasons, a new collider called the International Linear Collider (ILC) is being planned. This
Zirkon (ZrSiO4) och baddeleyit (ZrO2) är två vanliga zirkoniuminnehållande mineral som båda är viktiga för U-Pb-geokronologi. Zirkon är stabilt under kiselmättade förhållanden medan baddeleyit under kiselmättade förhållanden torde reagera med det tillgängliga kislet och bilda zirkon. Trots detta har baddeleyit observerats som interna domäner i zirkon i kiselmättade bergarter från exempelvis sydväsZircon (ZrSiO4) and baddeleyite (ZrO2) are two common zirconium bearing minerals which are important for U-Pb geochronology. Zircon is stable at silica saturated conditions, while baddeleyite should react with the free silica to form zircon under the same conditions. Yet, baddeleyite have been observed as intergrowths within zircon grains in silica saturated rocks, e.g. from southern West Greenlan
Psychological distress, including depression, anxiety, and stress, requires time-efficient assessment tools suited for digital and momentary settings. The Screening Tool for Psychological Distress (STOP-D) is a five-item scale developed for brief mental health screening, but it has not yet been validated in Swedish. This study aimed to evaluate the psychometric properties and diagnostic accuracy o
Accurate grading of Oil Palm Fresh Fruit Bunches (FFB) is pivotal for maximizing agricultural yield, yet manual assessment in unstructured environments remains labor-intensive and subjective. While Convolutional Neural Networks (CNNs) offer an automated solution, the conventional strategy of scaling network depth often yields diminishing returns or overfitting on moderately sized datasets. To over
Heterogeneous catalysts based on Single Atom Alloys (SAA) play a significant role in numerous technical processes. The fundamental working principles of these systems, however, remain poorly understood, especially the aspects related to the nanoscopic nature of bimetallic particles and the associated structure-reactivity relationships. In this study, we developed for the first time well-defined SA
Background: Standardized care pathway (SCP) for macrohematuria (patients aged ≥50 years) in Sweden includes four-phase computed tomography urography (CTU) before cystoscopy, but targeted SCP lead time for CTU (6 days)/treatment is fulfilled in <25% of patients. Purpose: To retrospectively analyze the incidence of CTU-diagnosed upper urinary tract (UUT), kidney and bladder tumors, calculi, radiatio
Small and medium-sized enterprises (SMEs) often face unique challenges in integrating advanced digital technologies due to limited resources and organizational constraints. While much attention has been given to large firms' adoption of big data analytics (BDA) and artificial intelligence (AI), less is known about how SMEs can leverage these tools effectively. This study addresses the research que
This paper presents a lifetime assessment of a marine leisure vessel propulsion and charging architecture comprising Dual Active Bridge (DAB) converters and a threelevel Neutral Point Clamped (NPC) inverter with Boat-To-Grid (B2G) capability. Analytical lifetime models, combined with thermal-electrical simulations and realistic operating profiles, are used to estimate the durability of semiconduct
The rapid expansion of the global microgrid (MG) market requires a sustainable and resilient energy storage solution to manage the intermittent nature of renewable energy sources. While conventional battery storage systems are common, they present significant limitations in cost, lifespan, and environmental impact. This paper introduces green hydrogen energy storage (GHES) as a paradigm-shifting a
Time-domain induced polarization (TDIP) data carry spectral information that can be used for petrophysical interpretation. At the same time, TDIP data can be collected in the field more efficiently than frequency-domain induced polarization (FDIP) data, thanks to the use of square-wave signals. However, TDIP field data are prone to noise, particularly strong near industrial installations and urban
Ouagadougou is a city with three million inhabitants and an increasing demand for water of sufficient quality. New boreholes are drilled to match demand, but their protection from anthropogenic contamination is insufficient. To assess the quality of urban groundwater in Ouagadougou for the first time, a total of 32 borehole water samples were collected and assessed for bacteriological and physicoc
The communicating home concept has been defined by identifying the dominating communication technologies to/from and in the homes, the most important customer behavior and user needs, the dominating products and the dominating actors of the industry. The evaluation of the communicating home industry has been performed with a five forces framework analysis and theories regarding value migration and
Problem: Since business process management (BPM) is a very spacious concept, it is influenced from many other concepts, standards and methods that determine its constancy. Companies are asked to restructure their organisation in order to meet internal and external customer demands. The term quality comes to the fore. Organisations such as ISO and the EFQM try to certify or assess companies in term
