2. 1. Secondary Nucleation in Amyloid Formation

   Author : Mattias Törnquist; NanoLund: Center for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; amyloid; Ab42; aggregation mechanism; aggregation kinetics; secondary nucleation; Protein misfolding;

   Abstract : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

4. 2. Systems Biology of the Secondary Metabolism in Filamentous Fungi

   Author : Jens Christian Froslev Nielsen; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; genomics; systems biology; secondary metabolites; antibiotics; Next-generation sequencing; secondary metabolism; filamentous fungi; cell factories; Penicillium;

   Abstract : Filamentous fungi constitute a rich reservoir of pharmaceutically relevant bioactive small molecules. These compounds, commonly referred to as secondary metabolites, are widely used as antibiotics for the treatment of microbial infections, but also as other pharmaceuticals such as immunosuppressors, cholesterol lowering agents and anticancer drugs.

   Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; principal roles; leadership; secondary school; developing countries management; tasks; deputy principals; students; Cameroon; International and Comparative Education; internationell och jämförande pedagogik;

   Abstract : The main aim of this research was to explore the present role of the secondary school principals and the challenges they face in carrying out their duties in the Northwest region of Cameroon. The research, which was exploratory and conducted in the interpretive paradigm, is a case study which was carried out at eight secondary schools. READ MORE

6. 4. Secondary Metabolites from Mozambican Plants

   Author : Julião Monjane; Centrum för analys och syntes; []
   Keywords : Secondary metabolites; Mozambique; Medicinal plants; Isolation; Structural elucidation; Antileishmanial activity;

   Abstract : Products derived from different natural sources have been used for thousands of years by human beings for their everyday needs. Out of these natural sources, plants were the most affordable. Plant-derived products were used for shelter, food, and as medicines. READ MORE

7. 5. Thermophysical Properties of Aqueous Solutions Used as Secondary Working Fluids

   Author : Åke Melinder; Björn Palm; Antero Aittomäki; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary working fluids; secondary refrigerants; indirect systems; aqueous solutions; ice slurry; thermophysical properties; freezing point; density; viscosity; specific heat; thermal conductivity; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

   Abstract : Secondary working fluids (secondary refrigerants, heat transfer fluids, antifreezes, brines) have long been used in various indirect re-frigeration and heat pump systems. Aqueous solutions (water solu-tions) have long been used as single phase (liquid only) secondary working fluids for cooling in supermarkets, ice rinks, heat recovery systems, heat pumps and other applications.
