1. 36. Design and Synthesis of Potential Aminoacyl-tRNA Synthetase Inhibitors

   Författare :Itedale Namro Redwan; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aminoacyl tRNA synthetases; Aminoacyl-AMP; Bioisosteres; Amino Acids; Solution-Phase; Protective Groups; Solid-Phase Chemistry; Molecular Modelling; Biological Evaluation;

   Sammanfattning : Aminoacyl-tRNA synthetases (aaRSs) are essential enzymes present in all living organisms, their catalytic activity is involved in the translation of the genetic code into functional proteins and they are potential targets for anti-infective agents. The first step in the biosynthetic pathway catalysed by aaRSs consists of activation of the corresponding amino acid by the reaction with ATP to form an aminoacyl-adenylate (aa-AMP), the key intermediate in the biosynthesis of proteins.

   Författare :Victor Cucarella Cabañas; Gunno Renman; Greg Morrison; KTH; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Compact filter; Filtra P; Phosphorus recycling; Polonite; Soil amendment; Sorption isotherms; Soil science; Markvetenskap; Solution chemistry; Lösningskemi; Agricultural engineering; Jordbruksteknik; Water engineering; Vattenteknik; Environmental chemistry; Miljökemi;

   Sammanfattning : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. LÄS MER

4. 38. Improving Model-Based Systems Analysis of Waste Management

   Författare :Mattias Olofsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material recycling; modelling; import; energy recovery; greenhouse gas emissions; export; systems analysis; scrap markets; waste prevention; waste management;

   Sammanfattning : Model-based systems analysis is a tool to support decision-makers in the field of waste management. Of special concern in this thesis is the development of mathematical models for the analysis of the technological system. The aim of the models (here denoted WMS models) is to address whole waste management systems, i.e. LÄS MER

5. 39. Exploring different thermoplastics from lignocellulosic building blocks and monomers

   Författare :Olivier Bonjour; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biobased plastics; Biobased polymers; Polymethacrylates; Polycarbonates; Polyesters; Poly beta-thioether ester s; Chemical recycling; Biobased plastics; Biobased polymers; Polycarbonates; Polymethacrylates; Poly beta-thioether ester s; Polyesters; Chemical recycling;

   Sammanfattning : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. LÄS MER

7. 40. Potential and problems related to reuse of water in households

   Författare :Eva Eriksson; Denmark Technical University of Denmark; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural Science; Naturvetenskap; Technology byts ev till Engineering ; Teknik;

   Sammanfattning : There is a growing demand in society for the introduction of decentralised sanitary reuse systems and the main reason for this is that centralised urban sanitation systems are expensive and resource-intensive. A second is water shortage and one way to reduce the need for freshwater is to reuse wastewater on-site. LÄS MER
