  1. 1. Effect of Physical Weathering on Mechanical Properties of Tailings

    Författare :Juan Rodriguez; Kauko Kujala; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : The mining activity produces minerals to supply to the modern society with commodities. During the ore refining process large amounts of tailings are generated as waste. Tailings are the result of crushing and wet milling, typically in the size range of sand to silt and angular in shape. LÄS MER

  2. 2. Importance of the particle shape on mechanical properties of soil materials

    Författare :Juan Rodriguez; Sven Wallman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Particle shape of soil aggregates is known to influence several engineering properties; such as the internal friction angle, the permeability, etc. Even if this is known, there has been only minor progress in explaining the processes behind its performance and has only partly implemented in practical geotechnical analysis.

  3. 3. Novel cerebrospinal fluid and blood tau biomarkers in Alzheimer's disease and other neurodegenerative diseases

    Författare :Juan Lantero Rodriguez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tau; Phosphorylation; Biomarkers; Alzheimer’s disease; CSF; Blood;

    Sammanfattning : Tau is a protein predominantly expressed in neurons in the central nervous system (CNS), where it binds microtubules (MT), playing a major role regulating their dynamics and architecture. Under pathological conditions, tau detaches from MTs, leading to neuronal dysfunction and cell death. LÄS MER

  4. 4. Targeting apoptosis-inducing factor as a novel therapeutic strategy for preventing perinatal brain injury

    Författare :Juan Rodriguez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AIF; neonatal; mouse; hypoxia-ischemia; AIF CypA complex; apoptosis; asphyxia; CHCHD4;

    Sammanfattning : Perinatal complications such as asphyxia can cause brain injuries that are often associated with subsequent neurological deficits. The mechanisms of perinatal brain injury are not fully understood, but mitochondria play a prominent role, not only due to their central function in metabolism, but also because many proteins with apoptosisrelated functions are located in the mitochondrion.

  5. 5. Microbial Synthetic Biology, Systems Metabolic Engineering and Enzyme Engineering for Advanced Microbial Biodiesel Production with Saccharomyces cerevisiae

    Författare :Juan Octavio Valle Rodriguez; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein rational engineering; wax ester synthase; hydrolase; advanced biofuel; fatty acid metabolism; directed evolution; chromosomal delta-integration;

    Sammanfattning : The continuous requirement of transportation biofuels has brought the necessity to establish alternatives permitting low-cost production of biodiesel while being environmentally friendly. Biodiesel production was achieved utilizing Saccharomyces cerevisiae by employing respective enzymes that catalyze the synthesis of fatty acid ethyl esters (FAEEs) based on fatty acyl-CoA molecules and ethanol.
