Using Plant Epidemiological Methods to Track Computer Network Worms
Network worms that scan random computers have caused billions of dollars in damage to enterprises across the Internet. Earlier research has concentrated on using epidemiological models to predict the number of computers a worm will infect and how long it takes to do so. In this research, one …

Thwarting Network Stealth Worms in Computer Networks through Biological Epidemiology
… and effective control of network stealth worms in digital networks through techniques based on biological epidemiology. Network stealth worms comprise a class of surreptitious, self-propagating code that spread over network connections by exploiting security vulnerabilities in hosts. Past …

Graph-theoretic Approach To Modeling Propagation And Control Of Network Worms
… society, cyber attacks with network worms have become the predominant threat to confidentiality, integrity, and availability of network computing resources. Despite ongoing research efforts, there is still no comprehensive network-security solution aimed at controling large-scale worm …

Automated signature generation for Zero-day polymorphic worms using a Double-honeynet
… signature generation for Zero-day polymorphic worms. Thesis consists of two parts: In part one, polymorphic worm instances are collected by designing a novel Double-honeynet system, which is able to detect new worms that have not been seen before. Unlimited honeynet outbound connections are …

An investigation of mechanisms to mitigate zero-day computer worms within computer networks
… quickly to identify and counter the effects of worms. In this thesis, an investigation of mechanisms to mitigate zero-day computer worms has been carried out, while defining the key research questions to answer. This thesis presents a novel distributed automated worm detection and containment …

The value of Mopane worms: quantifying ecosystem services in terms of nutrient cycling in semi-arid regions of Limpopo
Mopane worms are the late-instar stage caterpillars of the mopane moth, Imbrasia belina/ Gonimbrasia belina, found in southern Africa virtually following their hosts' trees, Colophospermum mopane, Terminalia seriscea, and Sclerocarya birrea, among others. The caterpillars are harvested for …

Understanding spatial structuring and the role of domestication in the development of sustainable harvest techniques of Mopane worms (Gonimbrasia belina).
… of sustainable harvest techniques of Mopane worms (G. belina). Spatial structuring of mopane worms was investigated at both a fine (10m x 10m) and medium-scale (1 km2) at sites with and without commercial harvesting. Mopane worm populations were experimentally treated through transplant …

Opening a can of worms : perceptions and practices of teachers in Newfoundland and Labrador incorporating the role of a therapist
Educational trends of inclusion and collaboration have led to changing roles of teachers, including an emphasis on personal support. To provide for social, emotional, and behavioural needs, teachers may adopt a therapeutic role. Many models for such support are proposed, with most models including …

Exploring challenges and intervention strategies for harvesting Mopane worms in conservation areas: A case study of selected areas in Vhembe District Municipality
… intervention strategies for harvesting Mopane worms at Ha-Gumbu, Matiyani, and Bokmakieries Farm in the Vhembe District. It was observed that conservation areas in South Africa continued to use pesticides and deforestation, which could potentially lead to the extinction of Mopane worms. …

Impacts of Invasive Asian Jumping Worms on Soil Properties in Turfgrass Systems and their effects on Plant Nutrient Acquisition and Physiological Responses in Greenhouse Experiments
… the ecological impact of invasive Asian jumping worms (Amynthas spp.) in turfgrass systems and controlled greenhouse conditions. In the field, we evaluated jumping worm presence using environmental DNA (eDNA) and assessed associated changes in microarthropod abundance, microbial enzyme activity, …

Transcriptome characterisation of the intra-mammalian stage of male and female Schistosoma mansoni
… Schistosomes are dioecious and male and female worms find one another and pair in the blood vessels of the host’s liver. This sets in motion a unique feature of schistosome biology, the pairing-dependent sexual maturation of the female worms. Over the course of the next three weeks, the females …

<em>In Vitro Cultivation</em> of the Microphallid Trematode <em>Gynaecotyla Adunca</em>
… I decided to test <em>G. adunca</em> adult worms to either confirm or refute whether this is true or not. I also tested different culture conditions on adult <em>G. adunca</em> worms. I chose 3 parameters to evaluate <em>in vitro</em> cultivation experiments. To determine these parameters …

Automated Defense Against Worm Propagation.
Worms have caused significant destruction over the last few years. Network security elements such as firewalls, IDS, etc have been ineffective against worms. Some worms are so fast that a manual intervention is not possible. This brings in the need for a stronger security architecture which can …

Detecting worm mutations using machine learning
Worms are malicious programs that spread over the Internet without human intervention. Since worms generally spread faster than humans can respond, the only viable defence is to automate their detection. Network intrusion detection systems typically detect worms by examining packet or flow logs for …

Carbon Dioxide Fixation in Schistosoma Mansoni
… mice sixty to seventy days post infection. The worms were then incubated in Eagle’s minimal essential medium with glutamate and 0.03 mg/100 ml of nonlabelled aspartic acid. To this medium was added 10 μc of either NaH<sup>14</sup>0<sub>3</sub>, glucose-UC<sup>14</sup> or …

Antischistosomal structure-activity relationships of nitrated n-phenyl benzamide derivatives.
… lacks antischistosomal activity against juvenile worms, does not provide a 100% cure, and does not prevent re-infection. N-phenylbenzamides have shown potential as antischistosomal agents although they have not been extensively studied. This study was inspired by one compound, MMV687807, which was …

Treatment of Wet Fish Sludge with Vermicomposting
… (mixed with cardboard) as a feedstock for the worms involved in the vermicomposting process. The results showed that as the percentage of fish sludge in the feed increased from 0 to 50%, there was a corresponding increase in the growth rate of E.fetida biomass. The filter bed test appraised the …
