Archaeological conservation using polymers : practical applications for organic artifact stabilization by C. Wayne Smith( Book )

14 editions published in 2003 in English and held by 258 WorldCat member libraries worldwide

"Working with Dow Corning Corporation, Texas A & M's Archaeological Preservation Research Lab (APRL), and the Conservation Research Lab (CRL), Smith and his colleagues in AS & M's Nautical Archaeology Program set out to develop a series of chemistries and techniques that would provide successful and affordable treatment strategies for organic materials. In this ground-breaking description of the processes and materials that were developed, Smith explains these techniques in ways that will allow museums and historical societies to conserve more stable artifacts for traveling exhibits and interactive displays and will allow researchers to conserve new discoveries without sacrificing important information."

Analysis of the weight assemblage of Port Royal, Jamaica by C. Wayne Smith( Book )

2 editions published in 1995 in English and held by 3 WorldCat member libraries worldwide

The assemblage of weights recovered from excavations at Port Royal, Jamaica is the largest collection of seventeenth-century weights recovered from a single colonial site. On June 7, 1692, just shortly before noon, an earthquake shook the community of Port Royal and in a matter of minutes, due to a process known as liquefaction, approximately thirty-two acres of the colonial port community sank below the waters of Kingston Harbor. To date, 90 weights have been recovered from nautical and terrestrial excavations at the site. Many of these bear the stamps and ciphers of English trade guilds as well as owners marks and regal stamps of authority. Several weights in the collection also bear a mark in the shape of a dagger or sword, which is associated with the City of London. Bronze and lead weights bearing cipher stamps offer a unique opportunity for archaeological and historical investigation. Combining data from archaeological excavations with information from wills, inventories and data from comparative assemblage known as the Streeter Collection, will result in a multi disciplinary analysis of the weights collection that has the potential for contributing a great deal of information about local and long distance trade and commercial patterns in colonial Jamaica. From a micro perspective, this analysis will contribute to the broader understanding of life and economic activities within the excavated area of the colonial port community. From a macro perspective, analysis of the weights should corroborate reforms in English law regarding the economic necessity for standardization of weights. Analysis of weight iconography suggests differences in mind-set that may have contributed in placing England apart from other European countries, in an advantageous position to become a leading economic force in the seventeenth century. An in depth analysis of the weight collection associated with seventeenth century Port Royal will draw many sources of data together, offering new perspectives on the colonial Jamaican process
Single Plant Selection as a Screening Method for Resistance to Rhizoctonia solani and Pythium ultimum in Cotton by Whitney Minton Jones( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Upland cotton, Gossypium hirsutum L., is grown extensively in the southern United States with an annual farmgate value of $6 billion and an annual national economic impact of over $120 billion. Damage due to biotic pests, including what is known as the cotton seedling disease complex (CSDC), contribute to these losses. Two particular CSDC pathogens, Rhizoctonia solani and Pythium ultimum, are the most significant soilborne pathogens of cotton in the United States. A program for R. solani and P. ultimum resistant cotton germplasm was established at Texas A&M University AgriLife Research. Five germplasm families selected for elevated levels of condensed tannins were evaluated for resistance to R. solani and P. ultimum. Two generations of single plant selections resulted in three generations, C₀ (original families or Cycle 0) C₁, selected from the C₀ family, and C₂, selected from the C₁ generation. C₁ and C₂ were putative resistant families after one or two generation(s) of selection, respectively. Individual plants from the three generations within five families were challenged with either or both R. solani or P. ultimum to evaluate the progress of single plant selection for resistance. A susceptible cultivar for R. solani- and P. ultimum-resistance respectively, were included. Different R. solani and P. ultimum families from each generation of selection were evaluated at three inoculation levels with four replications per family. Differences in level of resistance between each generation were evaluated by comparing disease level in a randomized complete block. Cross-resistance was evaluated, i.e., C₂ families originally screened under R. solani pressure were inoculated and screened for P. ultimum resistance and vice versa. Individual plant selection (IPS) in an artificial environment may be a useful and important tool in developing seedling disease-resistant cotton germplasm. Furthermore, it can be concluded that the family evaluated is of importance to determine the amount of progress made in terms of disease resistance with IPS. Individual plant selection when challenged with appropriate levels R. solani and P. ultimum appears to be an effective tool for selection of germplasm resistant to these seedling disease causing pathogens.

Genetics of Cotton Fiber Elongation by Eng Hwa Ng( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Fiber elongation (ability to stretch before breaking) is one of the key components in determining overall yarn quality. Elongation in U.S. upland cotton (G. hirsutum L.) has remained largely neglected due to: absence of monetary incentives for growers to produce high elongation cotton; lack of research interests among breeders; and absence of a reliable fiber testing system for elongation. This study was conducted to determine the genetics of cotton fiber elongation via a diallel and generation means analysis (GMA). Findings from this study should lay the foundation for future breeding work in cotton fiber elongation. Of the seven distinctive upland parents used for the diallel study, general combining ability was far more prominent than specific combing ability for fiber elongation. Cultivar PSC 355 and Dever experimental line were the two parents identified as good combiners for fiber elongation in this study. The slight negative correlation between fiber elongation and strength remained true. Highly significant negative correlation was observed between fiber upper half mean length and elongation. Both Stelometer and HVI elongation measurements correlated well with values of 0.85 and 0.82 in 2010 and 2011, respectively. For the six families used in the GMA analysis, additive genetic control was prevalent over dominance effect. Based on the scaling test, no significant epistatic interaction was detected for fiber elongation. As expected, additive variance constituted a much larger portion of total genetic variation in fiber elongation than the dominance variance. On average, larger numbers of effective factor were identified in fiber elongation than all other fiber traits tested, suggesting that parents used in the GMA study are carrying different genetic materials/ loci for fiber elongation. Considerable gains in fiber elongation may be achieved by selectively crossing these materials in a pure-line breeding scheme while holding other important fiber traits constant.

The accelerated degradation of conserved waterlogged wood by Karen Elizabeth Martindale( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

There is a great deal of variation in conservation treatments for waterlogged wood. There is also a great deal of variation in the environments where the artifacts are displayed and stored. Accelerated testing could be used as a tool to determine the best treatment for an artifact in a given environment, to adjust the environment to suit the artifact, or as a comparative tool for new conservation treatments. Accelerated testing methods used by manufacturing industries may be too expensive to be commonly used by conservation laboratories, but it is possible for conservation laboratories to create their own accelerated testing chambers that yield accurate comparisons. In this study, the author treats samples of archaeological waterlogged wood using PEG, freeze drying, and silicone oil treatments, then subjects the wood samples to four accelerated environments inside glass chambers. An "ideal" museum environment acts as a control, maintaining a temperature of 20-22°C (68-71.6°F), a relative humidity of 16%-20% using silica gel, and a lighting cycle of five days with light and two days without light; a museum with little environmental control is simulated by using a heated seedling mat to increase the temperature of the chamber to 28-3°C (82.4-86°F), increasing the relative humidity by adding 5 ml of water weekly, and has a lighting cycle of five days with light and two without light; outdoor storage building conditions are simulated by keeping the chamber in an oven programmed to maintain a temperature of 35°C (95°F), increasing relative humidity by adding 5 ml of water weekly, and limiting light; cool storage conditions are simulated by keeping the chamber in a refrigerator that maintains a temperature of 4-6°C (39.2-2.8°F), maintaining a relative humidity of 16%-20% using silica gel, and limiting light. At all stages, dimensions and physical changes of each sample were recorded and each sample was photographed. The samples reacted to the accelerated conditions in a predictable way: the samples treated with PEG were the most reactive to increased humidity, the samples treated by freeze drying reacted to a lesser extent, and the samples treated with silicone oil did not visibly react. The resulting conditions of the samples prove that meaningful comparisons can be made between samples, even without the specialized weathering chambers used by industry.

In A Different Light: An Examination of Artifacts Using Affordable Digital Infrared Imaging by Samuel Marshall Cuellar( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

The objective of this thesis is to analyze the visual effectiveness of inexpensive, converted near-infrared digital cameras on a variety of artifacts. Twenty-nine artifacts ranging in condition from unconserved to having completed conservation were chosen from five main type groups; bone, ceramics, metal, paper and textile, and wood. Each artifact was imaged with both a conventional dSLR and one specifically modified to image within the near-infrared band of the electromagnetic spectrum. Following imaging, the two types of photographs for each artifact were directly compared, analyzing visual changes between conventional and near-infrared. The changes were described and each object given a rating of "not recommended", "no change", or "recommended" in regards to infrared imaging unveiling useful data outside of that seen with normal photography. Of the twenty-nine artifacts imaged, thirteen were "recommended" as showing potentially useful information for researchers. While no definitive claims could be made due to the variety of responses across all five groups, organic artifacts, as a whole, tended to show the most potential of responding positively to near-infrared photography using modified dSLRs. Even though none of the five groups imaged consistently across all its artifacts, the ability of modified dSLRs to define patterns in staining and corrosion, differentiating inks, penetrating dirt and stained surfaces, and revealing wood grain and tree rings was well noted and showed the potential of making such cameras a useful part of an analytical toolkit for archaeologists.

Inheritance of Cotton Fiber Length and Strength by Kolbyn Seth Joy( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

The U.S. cotton industry has become predominantly an export market which requires a higher standard of fiber quality than does the domestic market. To remain competitive, U.S. cotton must meet the quality standards demanded by the consumers of raw cotton whether domestic or abroad. Diallel and generation means analyses (GMA) were conducted on fiber quality data of nine and five parental genotypes, respectively, to gain a better understanding of the genetic control of cotton fiber length and strength as well as to ascertain the value of the reported genotypes toward the improvement of fiber quality. Parental genotypes included extra-long staple uplands (Gossypium hirsutum, L.), EMS mutated uplands, high strength uplands, and interspecific hybrids. General combining ability (GCA) and specific combining ability (SCA) were estimated according to Griffing's diallel Model I, Method 4 for lint percent, high volume instrument (HVI) upper half mean length (UHML), fiber bundle strength (Str), uniformity index, elongation, micronaire, advanced fiber information system (AFIS) upper quartile length on a weight basis, mean length on a number basis, short fiber content on a number basis, immature fiber content, maturity ratio, and standard fineness. Estimates of GCA were significant across environments for all traits. SCA effects were significant for most traits but accounted for a smaller proportion of the variability in comparison to GCA effects. TAM B182-33 ELS would be the parent of choice to simultaneously improve fiber length and Str. The GMA was conducted on the parental, F₁, F₂, and backcross generations. Low levels of transgressive segregation for both UHML and Str were observed for some populations. Broad sense heritability ranged from 0.00 to 0.67 for UHML and from 0.22 to 0.82 for Str. Additive gene action was significant for all but three parental combinations for UHML and for all parental combinations for Str. Generally, the significance and magnitude of additive genetic effects were more consistent among parental combinations and years than were non-additive genetic effects for both UHML and Str. Dominance and epistatic genetic effects often were of a greater magnitude than additive genetic effects but in an inconsistent manner, and in both positive and negative directions.

Genetic Analysis, Inheritance and Stability of Mutation-based Herbicide Tolerance in Cotton (Gossypium hirsutum L.) by George Sherrod Cutts( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

The evolution of herbicide-resistant weed species in cotton production has created a need for new herbicide technology tools. Herbicide technologies not classified as genetically modified by recombinant DNA can provide tools with less associated registration and development costs and regulatory and market barriers. Research herein aims to advance herbicide crop tolerance through improvement and genetic analysis of mutation derived herbicide tolerance in cotton. Germplasm exhibiting elevated tolerance to the imidazolinone class of herbicides has been previously identified after mutagenesis with ethyl methanesulfonate (EMS). However, the physiological basis, genetic behavior, and potential for herbicide tolerance improvement are not fully understood and studies were designed to elucidate these factors. Three lines (EM₄-3-1-1, EM₄-3-1-2, and SCM₃-4-3-1) show high levels of imazamox tolerance. Data indicate that yield for all EMS treated lines was equal to or greater than their respective non-EMS treated cultivar. EMS treatment had no adverse effects on other cotton fiber properties. In 2012, levels of imazamox herbicide injury were seen at 14 days after application (DAA) ranging from 25-34 per cent. A greater level of injury was observed in 2013 ranging from 30-37% 7 DAA, and from 60-68% 14 DAA. Injury was transient throughout both growing seasons. Acetolactate synthase (ALS) gene sequencing characterized a mutation at Ala122 that is classified as conferring tolerance to imidazolinone herbicides, but was inconsistent in lines evaluated. Sequencing also revealed lines that have a truncated form of the protein in this region that may inhibit imidazolinone binding to the ALS protein. Chi-square analysis indicated this trait behaves in a simple, dominant fashion. Data from parent-offspring regression analysis indicated moderate correlation between parents and F₂ progeny (53%). Correlation is relatively high between F₂ and F₃3 progeny (84%) and demonstrates a strong relationship between these generations. Gain from selection indicates a 13.6% improvement in herbicide tolerance, lending to low progress from selection. These studies have shown that non-transgenic breeding methods can confer and improve imidazolinone herbicide tolerance in cotton, though levels of imidazolinone herbicide injury remained commercially unacceptable.
