Double-stranded RNA uptake in Caenorhabditis elegans
dsRNA uptake from the environment is a common phenomenon in many invertebrates and can be harnessed for acquiring pest control. In the nematode Caenorhabditis elegans, a transmembrane protein named systemic RNAi deficient-2 (sid-2) is required for dsRNA uptake from the environment through the …

Swimming sentinels : climate clues from stranded marine mammals
From skinny sea lions on beaches in California, to hundreds of enormous dead whales in the fjords of Chile, scientists have been recently puzzled by a spate of dead and dying marine mammals. These events are so complicated- influenced by disease, biotoxins, ecosystem changes, and human …

The Mechanism of Double-Stranded RNA Response in Neurospora
In eukaryotic cells, recognition of double-stranded RNA (dsRNA) by the enzyme Dicer initiates the RNA interference (RNAi) pathway, resulting in post-transcriptional gene silencing. Argonaute proteins play a critical role in this conserved pathway, which is present in protists, fungi, plants and …

Animal and Plant Viruses with Double-Stranded Ribonucleic Acid
… RNA, unlike any other known RNA, may be double-stranded. Results of physical-chemical studies have provided strong evidence to support this view. Purified reovirus contains 14.6% RNA and no DNA. The sedimentation coefficient of the virus, s<sub>20</sub>=630 S, is consistent with a minimum …

Molecular Dynamics Study of Single Stranded Peptide Nucleic Acids
… and dynamical properties of single stranded <em>aeg</em>PNA and <em>cp</em>PNA were undertaken to determine how the cyclopentane ring will improve binding and to determine the contributions of both entropy and dihedral angle preference to the observed stronger binding. The effects of …

Material Melancholy: Stranded Objects In Modern Southern Women's Writing
This dissertation traces the origins and uses of a specifically southern obsession with the past. Examining how southern women writers represent the compulsion to remember, I demonstrate how, in their narratives, efforts to retain intimate relationships with an idealized past obstruct characters' …

Growth and deterministic assembly of single stranded carbon nanotube
The ability to control the shape, position, alignment, length and assembly of carbon nanotubes over large areas has become an essential but very difficult goal in the field of nanotechnology. Current assembly efforts for nanostructures (such as carbon nanotubes) are mostly based on the concept of …

Frequency dependent impedance of stranded conductors using the subdivision method
… of frequency dependent resistance of stranded conductors in transmission lines has not been thoroughly investigated for a wide frequency range of DCto 10 MHz. The main objective of this thesis project has been to write a computer program that calculates the resistance and inductance of …

Slice implies mutant ribbon for odd 5-stranded pretzel knots
… holds for the infinite family of odd 3-stranded pretzel knots. In their work, they give a complete characterization of the slice/ribbon knots in that infinite family. This dissertation is motivated by their work and proves that the family of odd 5-stranded pretzel knots satisfiesa weaker …

Pathological role of double-stranded DNA antibodies in multiple sclerosis.
Multiple sclerosis is a complex disease and one for which the aetiology remains largely unanswered. Anti-dsDNA antibodies have been found intrathecally and bordering lesions in multiple sclerosis patients and in view of their known pathogenity in lupus nephritis the aim of this project was to …

Stranded kelp : its fauna and influence on sandy beach energetics.
… results of studies conducted on banks of kelp stranded on a sandy beach at Kommetjie on the west coast of the Cape Peninsula. The physical and chemical character of the beach are related to variations in the standing stocks and productivity of macro-, meio-fauna and bacteria as determined from …

Fluorescence imaging of single molecule dynamics on long single stranded DNA
… the progress has been largely limited to double-stranded DNA (dsDNA) or short single-stranded DNA (ssDNA). Here, a single molecule imaging approach for observing dynamics of proteins on long ssDNA of thousands of nucleotides in length is presented, with a detailed explanation on how to implement, …

W-reactivation (Inducible "SOS" DNA Repair) of double stranded DNA bacteriophage ? and single stranded DNA bacteriophage fd on isogenic rec and uvrB mutants of Escherichia coli K-12
… we looked at the W-reactivation of double stranded bacteriophage ? and single stranded bacteriophage fd. On examining the W-reactivation for phage ?, it is seen that the recB- and recF- mutants separately lead to a reduction of UV-reactivation efficiency but when spliced, the recB-recF- …
