Previous issue date: 2006-01-31 / The cassava (Manihot esculenta Crantz) is currently of great economic and social importance for Brazil. Important factors for evaluation of cassava cultivars under field conditions are: productivity (mg ha-1); Dry Matter Percentage (MS%). In order to carry out nutritional evaluation the following parameters must be considered: Fat - Ethereal Extract (EE%); Ash (%); Gross Digective Fiber (FB%); Gross Protein (PB%); Non Nitrogenate Extrative (ENN%) and Total Digestive Nutrient (NDT). The aim of this study was to verify differences between 16 cassava cultivars cultivates whit differents spacements: 0,60 m and 0,80 m whithin the line and 0,90 m between lines. The experimental design performed in random blocks with some treatments in common, with four repetitions. The results showed that the cultivars Espeto; Eucalipto e IAC 144-86 obtained smaller productivities. The cultivars Iracema; IAC 184-89; Fibra; IAC 89-87; Fécula Branca; IAC 32-88; IAC 14; Olho Junto; Mico; IAC 12; IAC 169-86; IAC 5-88; IAC 15 showed the highest yields. The bromatological characteristics didn't present statistical differences. The among cultivars 0,60m in the spacement increased the productivity in 12% when compared to the 0,80m spacement. / A mandioca (Manihot Esculenta Crantz) é atualmente de grande importância econômica e social para o Brasil. Fatores importantes para avaliação de cultivares de mandioca a campo são: produtividade (Mg ha-1) e o teor de Matéria Seca (MS%).

SPATIAL INTERPOLATION OF HEAVY METAL CONCENTRATIONS IN SOILS OF BUMPUS COVE, TNMagno, Melissa A, Luffman, Ingrid, Nandi, Arpita, Evanshen, Brian G 05 April 2018 (has links)
Mining processes generate waste rock, tailings, and slag that can increase heavy metal concentrations in soils. Un-reclaimed, abandoned mine sites are particularly prone to leaching these contaminants, which may accumulate and pose significant environmental and public health concerns. The characterization and spatial delineation of heavy metals of such soils is vital for risk assessment and soil reclamation. Bumpus Cove, once one of the richest mineralized districts of eastern TN, is home to at least 47 abandoned, un-reclaimed mines that were all permanently closed by the 1950s. This study evaluated 52 soil samples collected within a 0.67 km2 study area containing 6 known abandoned Pb, Zn, and Mn mines at the headwaters of Bumpus Cove Creek for heavy metal concentrations. Soil samples were analyzed for Zn, Mn, Pb, Cu, and Cd by means of microwave-assisted acid digestion and flame atomic absorption spectrometry (FAAS). Using the measured values and digital elevation model (DEM) derived from lidar data, ordinary kriging and cokriging interpolation techniques were used to predict the trend of heavy metal concentrations throughout the study area. Concentrations for Zn, Mn, and Pb show significant variability between sample sites (ranges of 12 – 1,354 mg/kg Zn, 6 – 2,574 mg/kg Mn, 33 – 2,271 mg/kg Pb). Cu and Cd were much less variable, with ranges of 1 - 65 mg/kg and 7 – 40 mg/kg, respectively. Of the measured heavy metals, only Zn and Pb exceed permissible limits in soils. Results show that ordinary kriging interpolation methods produced improved results over ordinary cokriging with and without lognormal transformations for all metals. Mn and Pb were found to transport further downhill following the natural drainage, whereas Zn, Cu and Cd concentrations exhibit localized variability without a clear transportation path. This study can provide a reference for state and local entities responsible for heavy metal monitoring in Bumpus Cove, TN.

A Historical Analysis of Cove Fort, UtahPorter, Larry C. 01 January 1966 (has links) (PDF)
With the passage of years a succession of families called Cove Fort their home. Members of these households served as agents for the facility and supervised its operation. A view of the personalities and occurrences associated with the various occupants is a necessary part of understanding that which has transpired at the site. The purpose of this thesis has been to gather and record that information which is currently available on the subject of the Fort. Each succeeding year diminishes the prospects of preserving certain valuable aspects of the history of that establishment which have not been previously committed to writing or made generally accessible to the would-be examiner.

Lost Cove, North Carolina: The Life and Death of a Thriving Community (1864-1957).Smith, Christy A. 15 December 2007 (has links)
This research examines the history and events that shaped the people and community of Lost Cove, an isolated Appalachian settlement. Chapter 1 surveys previous written and oral accounts of Lost Cove and the physical/cultural attributes of the community. Chapter 2 explores Lost Cove's identity, name, and first settlers. Chapter 3 explores the community's buildings and the families' livelihood. Chapter 4 examines the effect that the CC & O Railway and the sawmills had on the community. Chapter 5 examines moonshine selling in Lost Cove. Chapter 6 reveals how the church and school acted as a gathering place and how sermons and funerals were conducted. Chapter 7 explains why Lost Cove became a ghost town. Much of the information in chapters 3 through 7 is based on oral history interviews that the author did with former residents of the cove.

“You Want To Capture Something that Will Make People Change”: Rhetorical Persuasion in The Cove, Whale Wars, and Sharkwater.Stewart, Jessica January 2014 (has links)
Dolphins, whales, and sharks are some of the world’s most iconic animals. Yet, many people will only ever see these animals via the media. The media, then, hold significant power in creating, modifying, or reaffirming the imaginaries around various species which, in turn, influences how much concern is given to matters related to their welfare and conservation. Given the environmental and ecological concerns presently facing the ocean, protecting, conserving, and preserving the marine ecosystem is vital, and time is of the essence. Through the work of activists, three specific marine wildlife issues have received a lot of publicity across various forms of mainstream media: the killing of dolphins in Taiji, Japan for their meat; Antarctic whaling; and the practice of shark-finning.
Three activist films, namely The Cove (2009), Whale Wars (2008-), and Sharkwater (2006), are centred on these issues, and filmmakers attempt to compel viewers to support the activists’ protectionist cause. In order for this goal to have a chance of coming to fruition, rhetorical arguments must be carefully crafted. Yet, the study of rhetoric in animal-focused activist films is still an understudied research area.
This thesis contributes to this area of research by using the aforementioned films as case studies by applying Aristotle’s rhetorical proofs of ethos, pathos, and logos to analyse the rhetorical arguments. Ethos is demonstrable when the activists construct themselves as credible, moral heroes and the animals as possessors of positive traits worth protecting, and the hunters as immoral villains. The graphic imagery of animal death appeals to pathos to stir strong bodily and emotional responses such as sadness, and disgust in order to mobilize audience support for cause. Lastly, these films appeal to logos through the use of culturally authoritative discourses such as those of biology, western conventional medicine, and the legal system. This thesis essentially argues that these texts work rhetorically and discursively to persuade audiences to feel a connection with and sympathy towards the animals; to be supportive of the activists; and to prompt antipathy towards the hunters and industry spokespeople.

Metallogeny of a Volcanogenic Gold Deposit, Cape St. John Group, Tilt Cove, NewfoundlandHurley, Tracy 04 1900 (has links)
<p> The "B" horizon at Tilt Cove occurs in subaqueous mafic volcanics near the base of the Silurian Cape St. John Group. It is 3 metres below a well-banded oxide iron formation ("A" horizon). </p> <p>
Mineralization in the "B" horizon is analogous to that of the East Mine in that it is volcanogenic and has resulted in extensive chloritization of the footwall rocks, and in the deposition of banded sulphides or the replacement of the existing mafic volcanics by sulphides. There are differences in the geochemistry mineral textures and mineral types. The East Mine host volcanics are alkali depleted basaltic komatiites to
magnesium theleiites. The horizon host volcanics are spillitized magnesium tholeiites. Samples of ore from the East Mine show well-developed colloform and framboidal textures. Pyrite, magnetite, hematite and chalcopyrite are the dominant minerals with minor sphalerite and accessory
covellite. Samples from the horizon show relict colloform textures and framboids with less internal structure due to overgrowths. Atoll textures indicating extensive replacement are common. Pyrite is the dominant sulphide followed by sphalerite, chalcopyrite, accessory covellite and gold. The chalcopyrite occurs both as replacement of pyrite and exsolution in sphalerite. The most significant difference between samples from the East Mine and "B" horizon is the greater abundance of gold in the "B" horizon and its correlation with sphalerite. </p> / Thesis / Bachelor of Science (BSc)
