Streszczenie:

Hieracium species are a severe weed problem in the high country native tussock grasslands of New Zealand. This thesis reports on the potential for fungal biological control of Hieracium, in particular with a rust pathogen, Puccinia hieracii var. piloselloidarum. Isolates of Hieracium rust were collected from throughout Northern, Central and Southern Europe, and the British Isles. One thousand four hundred and twenty four isolates were screened on New Zealand Hieracium pilosella to identify the most infective strains for potential use as biological control agents. The rust isolates most pathoge

Streszczenie:

Colletotrichum gloeosporioides is the causal agent of anthracnose disease of mangoes. Infection occurs when humidity is high and rain-dispersed spores germinate and form an appressorium on immature mangoes. The infection then becomes quiescent until the fruit is harvested. On ripe fruit infection is visible as black, sunken lesions on the surface. At the pre-harvest stage, the disease is controlled with the application of a range of fungicides, and at the post-harvest stage by hot benomyl treatment. The extensive use of benomyl, both pre- and post-harvest, has resulted in the occurrence of iso

We have developed a new biofabrication process in which the precise control of bacterial motion is used to fabricate customizable networks of cellulose nanofibrils. This work describes how the motion of Acetobacter xylinum can be controlled by electric fields while the bacteria simultaneously produce nanocellulose, resulting in networks with aligned fibers. Since the electrolysis of water due to the application of electric fields produces the oxygen in the culture media far from the liquid-air boundary, aerobic cellulose production in 3D structures is readily achievable.

In a survey conducted in Zimbabwe in 1993, waterhyacinth was present in seven out of the eight provinces. No control measures were imposed on 35% of the infested dams and 61% of the infested rivers, while in 47% of the infested dams and 11% of the infested rivers control of waterhyacinth was being attempted with a combination of 2,4-D and mechanical control methods. The population of Neochetina eichhorniae and N. bruchi declined during the period 1993 to 1995 in the Hunyani River system. Several fungi were isolated from diseased waterhyacinth, and Fusarium moniliforme (isolate 2ex 12), F. sola

<p> Stochastic models of biochemical interactions elucidate essential properties of the network which are not accessible to deterministic modeling. In this thesis it is described how a network motif, the proportional-reversibility interaction with active intermediate states, gives rise to the ability for the variance of biochemical signals to be controlled without changing the mean, a property designated as mean-independent noise control (MINC). This noise control is demonstrated to be essential for macro-scale biological processes via spatial models of the zebrafish hindbrain boundary sharpen

A cell culture system was developed to study the production of prostaglandins by cervical cells from late pregnant guinea pigs. This permitted the examination of the influence of various substances on the synthesis of the prostaglandins, including progesterone and the anti-progesterone drug RU486 (Mifepristone/RU38486). RU486 has been found to promote cervical ripening in humans and guinea pigs. It is thought to increase the sensitivity of the uterus to prostaglandins and thereby promote muscle activity. It is licensed in the United Kingdom as an abortifacient. Since this antiprogestin can pro

Water lettuce, Pistia stratiotes Lamarck (Araceae) is a South American plant that has the potential to be a very damaging and important aquatic weed in many tropical countries, including South Africa. It has the potential to rapidly multiply vegetatively and completely cover watercourses in a very short space of time outside of its natural range under ideal conditions and without its natural enemies. In such instances, the weed may cause hindrances to water transport and fishing, increasing chances of malaria, as well as affecting the natural ecology of the system. Water lettuce can also set s

Current revolutions in biotechnology and neuroscience are changing military technologies, necessitating dramatic re-evaluations in arms regulatory regimes. This study assesses how these new technologies can be used in weapons systems - by governments and terrorists alike - and whether this frightening development can be brought under effective international control. Malcolm Dando begins by surveying the existing (and arguably inadequate) control mechanisms for chemical and biological weapons. He then discusses how earlier generations of toxin and bioregulatory weapons have been used by such st

Streszczenie:

The vast majority of the research efforts in finite capacity scheduling over the past several years has focused on the generation of precise and almost exact measures for the working schedule presupposing complete information and a deterministic environment. During execution, however, production may be the subject of considerable variability, which may lead to frequent schedule interruptions. Production scheduling mechanisms are developed based on centralised control architecture in which all of the knowledge base and databases are modelled at the same location. This control architecture has d

Streszczenie:

Hyperthermia is a cancer treatment modality that raises cancerous tissue to cytotoxic temperature levels for roughly 30 to 45 minutes. Hyperthermia treatment planning refers to the use of computational models to optimize the heating protocol to be used in a hyperthermia treatment. This thesis presents a method to optimize a hyperthermia treatment heating protocol. An algorithm is developed which recovers a heating protocol that will cause a desired amount of thermal damage within a region of tissue. The optimization algorithm is validated experimentally on an albumen tissue phantom.<p> The tra
