Sums and covers in categories
… in the sense of Zurab Janelidze. We study covers and sums at this level, abstracting a number of results and constructions known for coproducts. We examine the dual notion of a product structure and show that these coincide with independence structures of Alex Simpson. We show that …

Protection Covers for Trafficked Turf
… on the turf surface. Trafficked turf protection covers, which are field covers meant to be placed directly on the turf surface where pedestrian or vehicular traffic is expected and/or equipment will be placed, can be used to minimize damage to the turf surface. Scientific data on turf response to …

Fault covers in reconfigurable VLSI chips
Reconfigurable chips can be used to enhance the yield of chip production. These chips contain redundant elements that can be used to replace the defective elements. The fault covering problem is to assign the redundant elements to the defective elements such that the chip will function properly. We …

Incidence of Staphylococcus Aureus on Fomentation Covers
… study was to ascertain whether fomentation covers were contaminated with <em>Staphylococcus aureus</em> prior to being placed on a patient receiving a hydrotherapy treatment.</p> <p>From a review of literature on the subject of the <em>Staphylococcus aureus</em> organism and from studies of …

Covers and invariants of Deligne-Lusztig curves
… we use a ray class field construction to produce covers of each of these three families of curves which meet the Hasse-Weil bound over suitable base fields. In the Hermitian case, the family of covers constructed coincide with the family of Giulietti-Korchmáros curves. In the second part, we study …

Enriching low-order finite elements by interpolation covers
This dissertation presents an enriched finite element procedure based on the use of interpolation cover functions for low-order finite elements, namely, the 3-node triangular and 4- node tetrahedral elements. The standard linear finite element shape functions are coupled with interpolation cover …

Making meaning of grade 10 History textbook back covers
… make meaning of Grade 10 History textbook back covers. This qualitative study was informed by the interpretivist paradigm and aimed to investigate the multi-layered meanings that may arise when textbook back cover elements are analysed to discover their meaning and intention. A purposive sample …

Local-to-Global extensions for wildly ramified covers of curves
Given a Galois cover of curves X --> Y with Galois group G which is totally ramified at a point x and unramified elsewhere, restriction to the punctured formal neighborhood of x induces a Galois extension of Laurent series rings k((u))/k((t)). If we fix a base curve Y, we can ask when a Galois …

Calibration of sonographic gel probe covers for in-vivo mechanical testing
… cover. The mechanical properties of the covers vary with each cap as well as with time and temperature. Therefore, in order to ensure accurate measurement, the probe covers must be calibrated prior to use. An experimental study was carried out to examine the effects of various testing …

Using Covers and Wetting Agents to Prevent Winter Injury of Ultradwarf Bermudagrass
… exposure and tissue desiccation. Protective covers reduce low-temperature exposure on ultradwarf bermudagrass greens. Desiccation of turf can be caused by hydrophobic soils. Wetting agents are applied to actively growing ultradwarf bermudagrass greens to relieve symptoms of hydrophobic soils. …

Quantifying Methane Emissions from Sewer Covers in an Urban Sanitary Wastewater Collection Network
Sewer covers present an interface for biogenic methane (CH4) gas produced in the wastewater collection and transportation system to escape to atmosphere as an emission. However, the contribution of these emissions to municipal CH4 footprints is not well understood. In the research conducted for …

The effect of Cloth Stoma Covers on the tracheal climate of laryngectomised patients
… in South Africa and many other countries. Stoma Covers are simple devices made of a single fabric or combinations of fabrics that are fastened around the neck with the cloth covering the tracheostoma. They are relatively inexpensive to manufacture and can be washed and re-used. No research has …

The Effect of Complete Vineyard Floor Ground Covers and Root Pruning on Cabernet Sauvignon
Complete vineyard floor cover cropping and root pruning (RP) were evaluated for their ability to regulate excessive vegetative growth and improve berry and wine composition of ‘Cabernet Sauvignon’ (Vitis vinifera L.). Treatments were: tall fescue (Festuca arundinacea Shreb.) ‘KY-31’ and ‘Elite II’, …

Classification of infiltration characteristics of depressions in landfill covers using uncalibrated, thermal-infrared imagery
Landfill covers are intended to promote runoff and prevent water infiltration into the wastes. Water infiltrating through an earthen cover can mix with the wastes causing an undesirable increase in the amount of leachate and methane generated by decomposition. A common failure of the design is the …

Integrating Lesotho economy into the regional automotive value chain : manufacturing of car-seat covers
… identify Lesotho's potential to produce car seat covers for South African automotive assembly plants, and find the best trade policies and programmes to support value chains in the sector. The plan was to assess the possibility for Lesotho made automotive components manufacturers to supply the …

Effect of Protective Covers Against Biotic and Abiotic Disorders for Grape Production in Virginia
… the efficacy of paper bags, umbrella-style covers, and fruit-zone shelters in mitigating fungal diseases, insect infestations, and other factors that damage grape clusters. A series of field experiments were conducted at four commercial vineyards in Virginia and one research experiment …
