A molecular pentafoil knot and related circular helicates

Ayme, Jean-François January 2016 (has links)
Knots are being discovered with increasing frequency in both biological and synthetic macromolecules and have been fundamental topological targets for chemical synthesis for the past two decades. However, only few synthetic molecular knots have been prepared to date and their properties remain largely unexplored. This thesis reports the synthesis of the most complex non-DNA molecular knot prepared to date: the self-assembly of five bis-aldehyde and five bis-amine building blocks around five metal cations and one chloride anion forms a 160-atom-loop molecular pentafoil knot (five crossing points). Chapter I aims to give the reader an overview of the current state of research in the field of template synthesis of molecular knots. Chapter II reports the synthesis and full characterisation of the most complex non-DNA molecular knot prepared to date, a pentafoil knot. Chapter III describes the synthesis of eleven pentameric cyclic double helicates derived from the scaffold of a pentafoil knot and presents an extensive study of the factors influencing the assembly process. Chapter IV reports the study of the self-sorting behaviour of a molecular Solomon link and a molecular pentafoil knot and their related non-interlocked systems. Chapter V the dynamic nature of pentameric circular helicates and a pentafoil knot is investigated, bringing insights on the subtle balance of thermodynamic and kinetic parametres involved in their self-assembly process. Chapter VI describes the halide binding properties of a synthetic molecular knot and doubly- and triply-entwined [2]catenanes based on circular Fe(II)-double-helicate scaffolds.

Algebraické struktury pro barvení uzlů / Algebraic structures for knot coloring

Vaváčková, Martina January 2018 (has links)
Title: Algebraic Structures for Knot Coloring Author: Martina Vaváčková Department: Department of Algebra Supervisor: doc. RNDr. David Stanovský, Ph.D., Department of Algebra Abstract: This thesis is devoted to the study of the algebraic structures providing coloring invariants for knots and links. The main focus is on the relationship between these invariants. First of all, we characterize the binary algebras for arc and semiarc coloring. We give an example that the quandle coloring invariant is strictly stronger than the involutory quandle coloring invariant, and we show the connection between the two definitions of a biquandle, arising from different approaches to semiarc coloring. We use the relationship between links and braids to conclude that quandles and biquandles yield the same coloring invariants. Keywords: knot, coloring invariant, quandle, biquandle iii

EVALUATION AND GENETIC ANALYSIS OF TWO SOYBEAN [Glycine max (L.) Merr.] RECOMBINANT INBRED LINE POPULATIONS SEGREGATING FOR RESISTANCE TO ROOT KNOT NEMATODE (Meloidogyne incognita)

Wright, Drew Welsey 01 December 2012 (has links)
One of the most economically important pathogens of US soybeans is the Southern Root Knot Nematode [(Meloidogyne incognita) (Kofoid and White) Chitwood] (Mi). Evaluation and identification of resistance is highly important to the plant breeding program at SIUC. The main objective of this study was to screen within the greenhouse two F5:7 recombinant inbred line (RIL) (n=96) from crosses between LS90-1920 or LS97-1610 (resistant parents) with `Spencer' (susceptible parent) to identify sources of resistance for Mi. Additionally, the RILs were evaluated in two locations in southern Illinois (Harrisburg and Dowell) in 2011 for several agronomic characteristics including yield performance. The phenotypic data collected from field and greenhouse experiments was used to select for superior lines within the two populations. The screening data was also used to identify single nucleotide polymorphism (SNP) markers associated with Mi resistance. Initial screening of the 5,361 SNP markers indicated four SNP markers (ss247062763, ss247064854, ss247077423 and ss247067293) highly associated with resistance to Mi. The results will help accelerating selection practices, and have provided high yielding resistant lines for the creation of resistant commercial varieties.

A study of binding in three folds : sculpture as a knot

Mckay, Kathleen January 2016 (has links)
This thesis constitutes a piece of practice-led research: its principal research aim is to reflect on, analyse, and explore the conceptual, cultural, and artistic framework within which the offered artworks stand. The introduction is designed to provide an overview of both the central ideas to be discussed and the methodology to be deployed. It will also offer a snapshot of the structure of the text as a whole. As I will indicate, both method and content can be approached via a common guiding form: that of the fixed bind or knot. I will begin by introducing those concepts as they apply both to my own works and to those with which I have brought them into relation. My central concern is with the way in which the imagination forms connections and associations, the way objects or visions are gathered together in the imagination, and the way in which such ties might form knots, might amass or fix within them. I use the terms ‘binds’ and ‘bonds’ to refer to all such relations: to investigate these binds is to investigate the architecture of the imagination. My aim is to explore the way in which the structure of such binds might be present or affirmed in a physical object. In this context, the sculptures I have submitted can thus be understood as points of consolidation, points around which imagination amasses, and points at which binds accrue and abide: they are forms wrought and fixed, but not motionless, in the imagination. In this sense, from a theoretical perspective, to reflect on the sculptures is to reflect on what it means for objects or visions to bind and fixate in the imagination and for sculptors to realise them. For example, the first sculpture arises from attempting to make a seamless and ongoing circle of rope from lengths of hair. Here a material that stops once unbound from the head is repeatedly knotted. The longer binds thereby arise through a process of perpetual repetition in seeking to form a perfect bind; I juxtapose this vision of repetition with, for example, Kierkegaard’s work on that concept in order to analyse the nature of such a joint and impulse. As I have introduced the term, ‘binds’ therefore carries a double weight; it refers both to the structure of the imagination and to the sculptural connections that affirm it. The primary aim of this thesis is to investigate the interplay between these two aspects in both my own work and in that of a number of authors and artists.

KNOTS : A work about exploring design possibilities in draping based on principles of a knot.

Larsson, Jennifer January 2018 (has links)
This work is an exploration of design possibilities within draping based on a knot. This to show alternative possibilities and expressions through the knot in construction of clothing. The knot serves as a draping tool, has a function in each garment and is also decorative. The result is performed in 7 outfits based on experiments draped on a mannequin or my own body. The experiments are developed mainly through the branching strategy (Jones 1992)achieved with draping sessions in different materials, sizes and placements of the knot. Having the knot as starting point allows alternative expressions in construction of well known garments. It is also suggesting a method of closing a piece of clothing using the garment itself which could be developed further in 2D pattern construction.
