  2. 1. Ribosome standby sites and other structural aspects of translation initiation regions in Escherichia coli

    Author : Maaike M. Sterk; Gerhart E. H. Wagner; Fredrik Söderbom; Isabella Moll; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome standby sites; translation initiation; mRNA structure; bacteria;

    Abstract : Translation initiation, which is rate-limiting in protein synthesis, is often the step at which regulation occurs. Here, we investigated several mechanisms of translation initiation in Escherichia coli, including their control. READ MORE

  4. 2. A tale of trees and leaves : subtrees and local convergence

    Author : Wang Ruoyu; Stephan Wagner; Haslegrave John; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tree; subtree; mean subtree order; Benjamini Schramm convergence; local convergence; Mathematics; Matematik;

    Abstract : Given a tree T, a subtree in T is a subgraph that is a tree itself. The set of subtrees in a tree is related to many important graph parameters, one of which is the mean subtree order. READ MORE

  5. 3. Morphometric and Landscape Feature Analysis with Artificial Neural Networks and SRTM data : Applications in Humid and Arid Environments

    Author : Amir Houshang Ehsani; Friedrich Quiel; Wolfgang Wagner; KTH; []
    Keywords : Self Organizing Map; Neural Network; Morphometric Feature; Landscape; Yardang; Lut Desert; Potential natural vegetation; geoecosystem; Landform; Landsat ETM ; Morphometric Parameters; SRTM; Resolution; Curvatures; DEM.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents a semi-automatic method to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as an unsupervised Artificial Neural Network algorithm in two completely different environments: 1) the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) as a complex mountainous humid area and 2) Lut Desert, Iran, a hyper arid region characterized by repetition of wind-eroded features. In 2003, the National Aeronautics and Space Administration (NASA) released the SRTM/ SIR-C band data with 3 arc seconds (approx. READ MORE

  6. 4. Performance of Clay Liners in Near-Surface Repositories in Desert Climate

    Author : Laith Al-Taie; Frank Wagner; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Wars in Iraq (1991 and 2003) generated various types of hazardous waste (HW) in the form of soil contaminated by depleted uranium (DU). Other HW emanated from destroyed army vehicles and remnants of Iraqi nuclear facilities holding various types and amounts of chemical and radioactive material. READ MORE

  7. 5. Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment

    Author : Ida Järlskog; Yvonne Andersson-Sköld; Stephan Wagner; Statens väg- och transportforskningsinstitut; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-exhaust particles; tire wear particles; road dust; automated SEM EDX; environmental samples; optimized sample preparation; organic pollutants; street sweeping; traffic-derived microplastics; road simulator;

    Abstract : The prevalence of microplastic contamination has raised concerns about the potential risk and impact on the global environment. Traffic-derived microplastics, i.e., tire wear particles (TWP), polymer-modified bitumen, and road markings contribute to the emissions, and TWP are assumed to be one of the largest sources of microplastic emissions.
