Full textAbstract:
In this thesis I determine the effect of population decline on reproduction for two critically endangered African cedars. Widdringtonia whytei (Mulanje cedar) endemic to Mt Mulanje, in Malawi and Widdringtonia cedarbergensis (Clanwilliam cedar) endemic to the Cedarberg Mountains in the Western Cape Province of South Africa. Populations of both species have declined dramatically in the recent past and both show evidence of insufficient recruitment. Recent research has shown that a reduction in population density may limit pollen dispersal, reduce seed viability and increase self-pollination rates, causing an inbreeding depression, resulting in less fit offspring. Based on this research, I hypothesise that pollen transfer in Widdringtonia is distance-dependant and therefore populations with greater distances to the nearest adult neighbour will have lower seed viability, due to pollination failure. I also hypothesise, that trees which receive less outcross pollen due to distance-dependant pollination will have higher rates of self-pollination. I further hypothesise that seed viability may also increase with increased soil nutrients and more amenable climate differences linked to changes in altitude. To test these hypotheses, I determine the extent to which reduced population density has resulted in a decline in viable seed using germination experiments, followed by cut tests and tetrazolium chloride tests. For W. cedarbergensis seedling survival was determined in a greenhouse and self-pollination was assessed with ISSR markers, using DNA extracted from parent and offspring. My results show that seed viability for both W. cedarbergensis and W. whytei is not significantly correlated with distance to nearest-neighbour, altitude or soil nitrogen, carbon or phosphorus. These results suggest that current population densities are not effecting the reproduction either of W. whytei or W. cedarbergensis. My results for population genetics show relatively low levels of genetic variation in W. cedarbergensis typical of endangered and endemic species. The genetic differentiation between populations is low, suggesting that pollen flow between populations is adequate and populations are not genetically isolated. I conclude that there is no evidence that population decline is causing any noticeable limitations on pollen transfer and reproduction in Widdringtonia.

The present research proposes a comparative study between O Mulato, by Aluísio Azevedo and The House Behind the Cedars, by Charles Chesnutt, aiming at verifying some evidence of race prejudice in the voice of the novels narrators. Due to that, I first tried to analyze some scientific theories which have defended the inferiority of the black race and their portrayal through various stereotypes found not only in the novels which constitute the corpus of this study, but also in some prior to them. Furthermore, I examined some concepts from Comparative Literature which guided not only the comparison between the two frontier novels but also the use of notions from Science, History and Religion. Thus, I verified that both narratives were analogous in various aspects, among which I mention: (1) small and prejudiced cities; (2) the chronological time of the plots determined by historical events; (3) thirdperson omniscient and intrusive narrators; (5) afro-descendent heroes portrayed with physical and cultural characteristics of white heroes; (6) the end of the heroes by death, and (7) interracial relationship as the intriguing element of racial discrimination portrayed in the novels. Among the individual characteristics of each book, I pointed out (1) the angle of vision in the narratives, since the world depicted in O Mulato is the world of white people whereas the world in The House Behind the Cedars is the world of black people, and (2) the consciousness of black ancestry, which is not found in the main character of the Brazilian novel and is always present in the main character of the American novel. Finally, I tried to answer the research question by concluding that I believe that there is a contradiction in the voice of the narrator, who, although telling a plot whose ideological function is to fight against race prejudice, corroborates the racist scientific theories by describing secondary characters in the narratives stereotypically and afro-descendent heroes with physical and cultural characteristics of white heroes
A presente pesquisa retrata a proposta de um estudo comparativista entre O Mulato, de Aluísio Azevedo e The House Behind the Cedars, de Charles Chesnutt, objetivando verificar algum indício de preconceito racial na voz do narrador dos romances. Diante disso, procurei, em primeiro lugar, analisar algumas teorias científicas que defendiam a inferioridade da raça negra e a sua representação na literatura através de vários estereótipos encontrados não só nas obras que se constituem o corpus deste trabalho, mas também em romances que os antecederam. Ademais, visitei alguns conceitos da literatura comparada que nortearam não só comparação entre esses dois romances de fronteira, como também a utilização de noções da ciência, da história e da religião. Verifiquei, assim, que as duas obras eram análogas em vários aspectos; entre eles, cito: (1) cidades pequenas e preconceituosas; (2) eventos históricos que determinavam o tempo cronológico das tramas; (3) narrador onisciente, em terceira pessoa e intruso; (4) narração com indícios de preconceito do narrador; (5) heróis afro-descendentes com características físicas e culturais de heróis brancos; (6) fim do herói pela morte e (7) relacionamento inter-racial como o elemento instigador do preconceito racial representado nos romances. Entre as características individuais de cada obra, apontei (1) o ângulo de visão de cada romance, já que o mundo representado em O Mulato é o mundo dos brancos, enquanto o de The House Behind the Cedars é o dos negros, e (2) a consciência da ascendência negra, ausente no protagonista da obra brasileira, mas sempre presente no da obra americana. Finalmente, procurei responder à pergunta de pesquisa, concluindo acreditar haver contradição na voz do narrador, que, apesar de narrar uma trama cuja função ideológica era combater o racismo, corrobora, na sua narrativa, as teorias científicas racistas, através da descrição estereotipada de personagens secundárias e da descrição dos heróis afro-descendentes com características físicas e culturais de heróis brancos

Full textAbstract:
This study investigates the phenomenon of “passing” for white and its effects on individuals, who “pass” or attempt to “pass.” The effects of “passing” that the study examines are the loss of the historical identity and the constant trauma of the psyche. Furthermore, this study examines the importance of the spirit(soul) of the “passing” person in returning to the African American community. The study is based on the premise that in order to gain the economic stability, education, and true freedom that are enjoyed by white society, persons have to “pass.” Therefore, African Americans who can cross the color line risk their lives and their sanity in hopes of capturing the American Dream. However, over time, these persons realize that the price of “passing” is too high, and thus, return to the African American community via the spirit. Thus, this study concludes that although the person who “passes” relinquishes the history and suffers emotionally by way of the psyche, the spiritual connection plays an integral role of restoring him/her to the African American community.

As second-year graduate students from LMU’s Art Therapy program, we are excited to introduce the focus of our Master’s research project, a concept we coined as exhibition as intervention. Our goal is to create a space that brings awareness to the possibilities of exhibition to amplify the voice and increase empathy between artist and viewer. Originally, our vision was to hold the exhibition at Cedars-Sinai to supplement the 2020 Art Therapy Research Symposium. With COVID-19 placing restrictions on public gatherings, the exhibition had to transform from a physical experience to a virtual one. The catalog which began as our secondary focus to the exhibition, shifted to become the primary source of communicating our intentions. Informed by the literature of our research, we felt a catalog best collected and organized the data, which in this case was the artwork submitted. It is our great privilege to present this catalog with the works of artists engaging in the creative process to make meaning of their experiences with cancer.

Les inventaires mycologiques qui ont ete realises dans des cedraies du maroc et du sud de la france ont rendu compte de la diversite et de la specificite de la flore mycologique des cedraies. Des isolements de mycelia ont ete effectues a partir de basidiomes de champignons mycorhiziens fructifiant sous cedre. Certains sont specifiquement associes a cette essence (tricholoma cedrorum, tricholoma tridentinum var. Cedretorum, hebeloma eburneum). Les conditions de culture in vitro et la production d'inoculum de qualite des isolats obtenus ont ete optimisees et le caractere mycorhizogene de ces isolats a ete mis en evidence vis-a-vis de jeunes cedres cultives en conditions controlees, notamment pour la premiere fois pour certaines especes. L'efficacite des formes d'inoculum (solide et alginate) dans la mycorhization de semis de cedre varie en fonction de l'espece fongique. Des degres de mycorhization satisfaisants et des effets benefiques de l'inoculation sur la croissance des plants ont ete obtenus. Afin d'optimiser la production de racines courtes receptives a l'infection, on a etudie l'effet du substrat de culture, de la forme (nitrique et ammoniacale) et de la concentration en azote dans la solution de fertilisation sur l'architecture racinaire de semis de cedre en chambre climatisee. L'utilisation d'un substrat riche en attapulgite, seul ou en melange avec d'autres substrats artificiels mineraux, permet d'obtenir des ramifications des systemes racinaires des cedres meilleures et plus nombreuses que celles obtenues sur tourbe-vermiculite. D'autre part, l'utilisation du nitrate a 5 mm permet d'ameliorer la production de racines laterales et la densite de ramification du pivot par rapport au nitrate apporte a 0,25 mm ou a l'ammonium. L'inoculation des plants par du mycelium de tricholoma cedrorum suite a la predisposition des racines a mis en evidence des differences dans les degres de mycorhization suivant les traitements azotes. On a enfin etudie l'effet de la fertilisation phosphatee sur la mycorhization de semis de cedre en pepiniere. Les degres de mycorhization les plus eleves du cedre par tricholoma tridentinum ont ete obtenus avec une solution contenant 1,4 mm de p combine avec de relativement fortes teneurs en n et en k, appliquee de la troisieme a la huitieme semaine consecutivement a l'inoculation.

Silim, Salim Nahdy. "Regulation of cold hardiness in seedlings of western red cedar, yellow cedar and white spruce." Thesis, University of British Columbia, 1991. http://hdl.handle.net/2429/31514.
Full textAbstract:
The development and nature of cold hardiness was examined in first-year seedlings of the three conifer species: western red cedar (Thuja plicata Donn) from southern Vancouver Island, yellow cedar (Chamaecyparis nootkatensis (D. Don) Spach) from northern Vancouver Island and white spruce (Picea glauCa (Moench) Voss) from northern interior of British Columbia. The relationship between free thiols and the development of cold hardiness, and the effects of mefluidide on the induction of hardiness in the three species were also examined. To permit an accurate estimation of cold hardiness, a reliable method of determining hardiness based on the electrolyte conductivity method (EC) was developed for the three species.
Optimization of tissue preparation resulted in accurate and reliable estimates of cold hardiness in the three coniferous species. A comparison of visual assessment of shoot damage with the results obtained by the EC method indicated that the two methods were highly correlated although the EC method slightly overestimated the temperature at which 50% of the samples were killed (LT₅₀). The absolute lethal temperature (LT₁₀₀) estimated by the EC method was lower (3 to 7 °C) than that determined by the visual method.
The development of hardiness in the three species was characterized by different mechanisms: in white spruce it was initiated by short photoperiod, in red and yellow cedar it was basically regulated by low temperature. Low temperature (7/3 °C day/night) increased hardiness in all three species but subfreezing temperature (2/-3 °C day/night) increased the rate of hardening only in the two cedars. Furthermore, white spruce seedlings were apparently able to attain extreme levels of hardiness (below -65 °C) without exposure to temperatures below 0 °C. The ability to deharden in white spruce
was related to the satisfaction of chilling requirements while red and yellow cedar seedlings appeared to deharden only in response to warm temperatures.
Mefluidide (0.1 and 0.4 mg l⁻¹ ) applied as a root drench did not increase cold hardiness in any of the three species. Stomatal conductance was however decreased, thus resulting in increased shoot water potentials. Net photosynthesis was reduced predominantly due to stomatal limitations. Mefluidide increased synthesis of ABA in shoots of seedlings of the three species. The level of tissue ABA, like the other variables, was dependent on mefluidide concentration.
Low temperature (7/3 °C day and night, 9 h photoperiod, 250 μmoles m⁻² s⁻¹, 400 - 700 nm) induced an increase in free thiols (predominantly reduced glutathione) which was accompanied by an increase in hardiness. Although short photoperiod at a warm temperature (9 h, 20/15 °C day and night) increased hardiness in seedlings of white spruce, no significant increase in thiols was observed. Root application of buthionone sulfoximine and dichlormid affected tissue glutathione levels but these changes did not result in significant changes in freezing resistance. There appears to be no relationship between glutathione and freezing resistance.Forestry, Faculty of

Full textAbstract:
Extreme flooding of rivers may contribute to increased loading of persistent organic pollutants (POPs) to the Great Lakes, the Mississippi river, and other large lakes and surface waters downstream of industrial and urban areas. This study examines the fate of POPs that were mobilized during heavy flooding of the Cedar River and the small urban city of Cedar Rapids, Iowa during the summer of 2008. This study focuses polychlorinated biphenyls (PCBs). We hypothesize that these PCBs were mobilized by the flood water and that residues remained in the soils and sediments of the residential areas of the city. To test our hypothesis, soil samples were collected from ~200 of residential locations in the downtown Cedar Rapids area and analyzed for the three compound groups. Samples were extracted using an accelerated solvent extraction (ASE 300), and analyzed using GC/ECD, GC/MSD and GC/MS/MS.

Full textAbstract:
On June 13, 2008, after many days of rain, the Cedar River flooded the city of Cedar Rapids. With a peak discharge of 139,987 cfs and at 19.12 feet above flood stage, the 2008 flood of Cedar Rapids was the largest flood in the city’s historic record. As rivers rose, the city had received forecasts of an incoming flood as early as June 8. Then, on June 12, it began to rain in Cedar Rapids. Finally, on June 13, 2008, the Middle Cedar crested at 31.12 feet.
This thesis project modeled a variety of rainfall patterns on June 12, 2008, to determine the effect of varying rainfall intensity and location on the magnitude of the 2008 flood of Cedar Rapids. Using a method known as Stochastic Storm Transposition (SST), I overwrote precipitation data in a hydrologic model of the Middle Cedar Watershed with rainfall data extracted from specific storm events that occurred in the Upper Midwest. We used a physically-based, semi-distributed hydrologic model known as GHOST (Generic Hydrologic Overland-Subsurface Toolkit) developed by Marcela Politano at the University of Iowa.
Traditionally, hydrologic modeling for watersheds has used design storms to create rainfall inputs in flood modeling. These design storms have uniform rainfall timing and accumulation patterns across a watershed and are determined by designated equations for a geographic region. In large watersheds such as the Middle Cedar (2,400 square miles), design storms are not physically realistic because of their uniformity. Additionally, design storms fail to capture unique storm patterns such as high intensity periods or the movement of a storm across a watershed. By implementing SST into GHOST, we used physically realistic storm events that have unique rainfall patterns and intensities within a designated return period.
SST extracts rainfall data from real storm events and transposes the storm patterns onto watersheds to provide physically realistic rainfall data for hydrologic modeling. A tool called RainyDay, developed by Professor Daniel Wright at the University of Wisconsin, provided the storm transpositions used in this research. We assigned the storm transpositions return periods created by RainyDay, corresponding to their average transposed rainfall across the Middle Cedar Watershed.
Replacing the June 12 rainfall with RainyDay’s two-year transposed storm events (average rain accumulation 1.8 inches) resulted in modeled flood peaks larger than the unaltered June 12 flood peak. Storm transpositions of 5-, 10-, and 2,000-year return periods showed even larger peaks, illustrating the potential for floods much larger than the 2008 flood.
In addition to the analysis of flood magnitude in 2008, we modeled a set of storm transposition scenarios for a variety of soil-moisture conditions. The increased discharge levels in scenarios with high soil moisture emphasize the importance of initial conditions in flooding scenarios. Finally, we modeled the effect that two-year RainyDay storms would have had on the 2016 flood of Cedar Rapids had they occurred on the day before the peak. The two-year transpositions showed that with an impending flood crest smaller than the 2008 crest, several two-year RainyDay scenarios would have resulted in floods nearly equal in magnitude to the 2008 flood event.
Our manipulation of the rainfall in the Middle Cedar Watershed on June 12, 2008, using the GHOST model provided the opportunity to re-examine the influence that a specific day of rainfall had on the 2008 flood of Cedar Rapids. The potential for higher flooding under conditions of repeated rainfall and high soil moisture illustrates the susceptibility of the Middle Cedar Watershed to future flood events under similar conditions. Applying SST in hydrologic modeling also provided an opportunity to model a variety of rainfall scenarios and to better understand watershed responses to nuanced and physically realistic rainfall patterns.

Because the timber potential, rapid growth and adaptation to edaphoclimatic conditions, the Australian cedar has been outstanding in the segment of sawn wood. The goal of this work was to evaluate the effect of the inoculation of arbuscular mycorrhizal fungi on the accumulation of nutrients, growth and quality of Australian cedar seedlings. The production of the seedlings was conducted in a greenhouse for 150 days. The seedlings were produced from seeds sown directly in the pot. The treatments containing the AMF were: Entrophospora colombiana, Acaulospora morrowiae, mixed inoculum (E. colombiana + A. morrowiae) and SF (control). Transplanting was carried out in the municipality of Dona Emma - SC, where the experimental design was completely randomized blocks, with factorial scheme 4 x 3. The first factor was fungal treatment, while the second factor was N, P and K fertilization, with (22.5 kg ha-1 urea, 67.5 kg ha-1 P2O5, 33.7 kg ha-1 K2O) and 1 dose (45 kg ha-1 urea, 135 kg ha-1 P2O5, 67.5 kg ha-1 K2O). The 4 plants of the useful plot were collected after 120 days of transplanting. The variables height, dry matter of shoot, root dry matter, stem diameter, mycorrhizal colonization and N, P, K, Ca and Mg contents of the plant tissue of the cedar seedlings were evaluated. The quality indexes of seedlings were calculated. The results showed that the seedlings inoculated with mixed inoculum varied between 25 and 31 cm in height, and myotrophism was observed. E. colombiana and mixed inoculum provided increase of MSPA, MSR and DC. A. morrowiae and mixed inoculum showed greater mycorrhizal colonization. The inoculated seedlings presented higher H / DC and higher MSPA / MSR. A. morrowiae presented the lowest IQD. E. colombiana showed to be superior in the absorption of N. The treatments with FMAs showed positive influence on P. A. morrowiae and without fungus were not efficient in the absorption of K and Ca
Em virtude do seu potencial madeireiro, rápido crescimento e adaptação às condições edafoclimáticas, o cedro australiano tem se destacado no segmento de madeira serrada. Este trabalho teve por objetivo avaliar o efeito da inoculação de fungos micorrízicos arbusculares sobre o acúmulo de nutrientes, crescimento e qualidade de mudas de cedro australiano. A produção das mudas foi conduzida em casa de vegetação durante 150 dias. As mudas foram produzidas a partir de sementes semeadas diretamente no vaso. Os tratamentos contendo os FMAs foram: Entrophospora colombiana, Acaulospora morrowiae, inóculo misto (E. colombiana + A. morrowiae) e SF (controle). O transplantio foi realizado no município de Dona Emma – SC, onde o delineamento experimental foi em blocos inteiramente casualizados, com esquema fatorial 4 x 3, com 3 repetições. O primeiro fator foi o tratamento fúngico enquanto que o segundo fator foi adubação N, P e K, com três doses: 0 (sem adubação), 0,5 (22,5 kg ha-1 de ureia; 67,5 kg ha-1 de P2O5; 33,7 kg ha-1 de K2O) e 1 dose (45 kg ha-1 de ureia; 135 kg ha-1 de P2O5; 67,5 kg ha-1 de K2O). Coletou-se as 4 plantas da parcela útil após 120 dias do transplantio. Foram avaliadas as variáveis altura, matéria seca da parte aérea, matéria seca da raiz, diâmetro do caule, colonização micorrízica e os teores de N, P, K, Ca e Mg do tecido vegetal da parte aérea das mudas e calculados os índices de qualidade de mudas. Os resultados mostraram que as mudas inoculadas com inóculo misto variaram entre 25 e 31 cm de altura, sendo observado micotrofismo. E. colombiana e inóculo misto proporcionaram aumento de MSPA, MSR e DC. A. morrowiae e inóculo misto apresentaram maior colonização micorrízica. As mudas quando inoculadas apresentaram maior H/DC e maior MSPA/MSR. A. morrowiae apresentou o menor IQD. E. colombiana mostrou-se superior na absorção de N. Os tratamentos com FMAs apresentaram influência positiva sobre P. A. morrowiae e sem fungo não foram eficientes na absorção de K e Ca

Full textAbstract:
Cedrela fissilis Vell. é árvore alta (10 a 30 m) por 40 a 50 cm de diâmetro. Tronco retilíneo com sapopemas pouco desenvolvidas ou ausentes, mas quando atacado pela broca do ponteiro, Hypsipila grandela, é tortuoso. Casca grossa, dura, fissurada, de marrom a pardo - acinzentada. Folhas alternas com 8 a 24 pares de folíolos. Flores actinomorfas, unissexuadas, de 5 a 10 mm de comprimento reunidas em tirsos axilares. Os frutos são cápsulas lenhosas deiscentes de 3 a 10 cm de comprimento, que encerram de 30 a 300 sementes aladas, com até 35 mm de comprimento por 15 mm de largura. A polinização é realizada por insetos, possivelmente mariposas e abelhas e a dispersão de sementes é anemocórica. C. fissilis é uma das espécies arbóreas mais ameaçadas pelo corte seletivo e destruição da Mata Atlântica no centro-sul do Brasil, sua principal área de ocorrência, tornando a conservação dos seus recursos genéticos extremamente ameaçada pela redução populacional que vem sofrendo. Por outro lado, esta espécie tem um grande potencial para produção de madeira de alta qualidade, principalmente em plantios mistos, que estão se tornando economicamente viáveis pela escassez de madeira no mercado nacional e internacional, bem como, está sendo também muito utilizada em projetos de restauração de florestas tropicais. Neste contexto, torna-se fundamental o estudo da diversidade genética das populações remanescentes desta espécie e da estruturação desta diversidade. Este trabalho analisou dez populações de C. fissilis em cinco estados da região centro-sul do Brasil, visando analisar sua estrutura genética e inferir estratégias para sua conservação, bem como estabelecer critérios para a utilização dos recursos genéticos existentes. Foram desenvolvidos nove locos microssatélites para a espécie revelando 130 alelos em todas as populações. A endogamia nas populações foi relativamente baixa. As populações apresentaram diferenciação genética segundo o modelo de isolamento pela distância. As populações tanto da floresta estacional semidecidual como da floresta ombrófila densa apresentaram maior similaridade entre si. A estrutura genética interna de duas populações (Parque Estadual Intervales SP e Parque Estadual do Rio Doce - MG) mostrou uma distribuição aleatória dos genótipos. Já na população da Reserva Florestal do Matão PR, a estruturação espacial foi significativa, revelando uma similaridade genética entre os indivíduos mais próximos (até 30m). Indivíduos jovens e adultos foram analisados em duas populações (Parque Estadual Intervales - SP e Reserva Florestal do Matão PR) revelando uma diversidade gênica semelhante para os dois estádios nas duas populações. No entanto, observa-se uma tendência de aumento da diversidade gênica e diminuição de endogamia nos adultos em relação aos jovens. Estes dados permitem também inferir sobre outras espécies florestais similares, uma vez que não existem dados disponíveis sobre a diversidade genética em grandes regiões geográficas em espécies arbóreas da Mata Atlântica.Cedrela fissilis Vell. is a high tree (10 a 30 m) with a DBH between 40 and 50 cm. Rectilinear trunk with little developed or absent sapopemas, but when attacked by the Cedar Shoot Borer is crooked. Thick, hard, brown to gray bark. Alternate leaves from 8 to 24 leaflet pairs. Actinomorfic unisexual flowers, from 5 to 10 mm length, produced in groups. Fruits are wood deiscent capsules from 3 to 10 cm length, with 30 to 300 winged seeds, till 35 mm length by 15 mm wide. Pollination is conducted by insects, probably moths and bees and seed dispersion is anemocoric. Cedrela fissilis is one of the most endangered tree species due to the selective logging and destruction of Atlantic Forest in southern-center Brazil, its main distribution region. On the other side, this species has a grate production potential of a high quality wood, mainly in mixed stands, what becomes economically viable because the lack of wood in national and international market, as well as it is being used in restoration projects of tropical forests. Besides these facts, the conservation of genetic resources of this species is very critical by the drastic population reduction that it is suffering. In this context, it becomes very important the study of the genetic diversity of the remnant populations of this species and the structure of this variation. This study analyzed ten natural populations of C. fissilis in five states in the southern-center region of Brazil, aiming to examine their genetic structure and infer strategies for genetic conservation, as well as, establishes criteria to use the genetic resources. Nine microssatellites loci were developed for this species and revealed 130 alleles in all populations. Populations inbreeding was relatively low. Populations presented genetic differentiation following the isolation by distance model. Populations from the seasonal semi deciduous forest, as well as from the evergreen forest presented higher similarity among them. Internal genetic structure of two populations (Intervales State Park SP and Rio Doce State Park - MG) showed a random spatial distribution of genotypes. The population of Matão Forest Reserve PR showed a significant spatial structure, revealing a genetic similarity among near trees (till 30 m). Juveniles and adult plants were analyzed in two populations (Intervales State Park - SP and Matão Forest Reserve PR), showing similar genetic diversity for the two classes in both populations. But, we observe a tendency of increase in genetic diversity and decrease in inbreeding in adult plants in relation to juveniles. These data also allow inferring about other similar tree species, since there is no available data on the genetic diversity of Atlantic Forest tree species in large geographical regions.

The Cedar Street Historic District, located in Manistee, Michigan, is a neighborhood that has retained many of its historic residences which serve as reminders of the city's heyday. Manistee, Michigan, located on Lake Michigan in the northwestern region of the lower peninsula, had a prosperous past as a major lumber manufacturing city. At the turn of the century, it was the third largest shipping port on the lake next to Milwaukee and Chicago. Manistee residents who made their fortunes in lumber built some of the finest houses in the region. A large majority of thoseresidences are located in the Cedar Street Historic District. Two of the mansions in the neighborhood were designed by the renowned Chicago School architect William LeBaron Jenney; unfortunately, they were razed in the 1920s.The boundaries of the district were determined in a preliminary survey of the architecture of the neighborhood. The survey, combined with the historical account of the area and its residents, shows that the Cedar Street Historic District is an excellent candidate for listing on the National Register of Historic Places. In addition, guidelines are included to show how the character of the district can be maintained.The possibility of the placement of the Cedar Street Historic District on the National Register of Historic Places may create more awareness of the city's additional historical resources. If the other historic businesses, residences, and public buildings in Manistee are surveyed and documented, there may be enough resources to merit the designation of a Multiple Resource Area. This may allow for greater protection of the city's historic properties.Department of Architecture

Full textAbstract:
Widdringtonia cedarbergensis is an endangered conifer species in the western Cape, South Africa. This species is under serious threat of extinction and is being actively managed by Cape Nature Conservation in a small section of the Cedarberg mountains in an attempt to boost population numbers with a seedling replanting scheme and preservation of adults from fires. This study set out to determine levels of genetic diversity and fitness within and among populations of the Clanwilliam cedar for the following reasons: (1) to assess the level of genetic diversity; (2) to screen the seed source for the replanting programme; (3) to locate vigorous seedling sources for replanting and (4) to determine the effect of population size on genetic diversity and fitness. Starch gel electrophoresis was employed to assess levels of genetic variation within and among seven populations of W. cedarbergensis. W. nodiflora and W. schwarzii, two congeneric species, were incorporated into this section of the thesis as benchmarks against which to compare levels of genetic variation in W. cedarbergensis. The three species are different with regard to biology and distribution and predictions as to their population genetic structures were set up accordingly. A major difference in their biology is the resprouting behaviour of W. nodiflora in response to fire. Fitness components in populations of W. cedarbergensis were divided into reproductive and "ecological" traits, and seedling growth traits. Reproductive and ecological traits were measured in the field and seedling growth traits were obtained from a seedling growth experiment carried out in the glasshouse. Overall, 15 potential fitness traits were measured. The same seven populations were tested for differences in these fitness traits. This enabled an assessment of the seed source used for replanting, as well as alternative seed sources. All fitness variables were tested for a significant relationship with genetic variation measured as heterozygosity. The populations were rated according to population size, density and isolation and correlated with heterozygosity to determine whether there was any relationship. Seventeen enzyme loci were resolved for each species. Estimates of genetic diversity showed that W. cedarbergensis and W. schwarzii had low allelic variation. This was attributed to the effect of bottlenecks. High levels of inbreeding and population substructuring were found in W. cedarbergensis which suggested that trees were selfing possibly due to limited pollen movement between trees as a result of tree isolation and fine-scale fragmentation incurred by fires. Although allelic diversity in W. nodiflora was extremely high, high levels of inbreeding were found within populations which was attributed to selfing among resprouted ramets of the same genet. Tests for differences in fitness traits between populations revealed no population as the most consistently fit for reproductive and ecological traits for the fittest population, although two populations, DG and CPS, were consistently found to have the most vigorous seedlings. The replanting seed source, MB, showed adequately vigorous seedlings. Four out of fifteen measures of fitness were found to co-vary with heterozygosity. These were embryo abortion fraction, germination rate, shoot biomass and total biomass. Seeds and seedlings were more vulnerable to the effects of inbreeding than traits related to fecundity. These four traits, in tum, co-varied with other traits. The relationship between germination rate and seedling:parent ratio, in particular, indicated that genetic phenomena are impacting the demography of populations. Reductions in fitness occurred in several traits below 30% heterozygosity and became critical below 25% heterozygosity. 30% heterozygosity occurred below a population size scale of 4 (4000 individuals) and 25% heterozygosity occurred below a population size scale of 1 (250 individuals). Population size, therefore, seemed important in maintaining the genetic diversity of populations. The effect of population density on fitness was not effectively examined in this thesis and deserves further attention. The results of this thesis had several implications for conservation and active management. My recommendations were the following: (1) two populations, DG and CPS, are the best seed sources for the replanting programme and should supplement the current and most accessible seed source (MB); (2) Replanting should be aimed at boosting seedling:parent ratios in small populations such as WB and KK, as well as closing gaps between trees and clumps of trees as far as possible to facilitate pollen movement and therefore outcrossing; (3) the bottleneck is at a critical stage where adult tree survival is of profound importance in ensuring seedlings are outbred and every effort should be made to reduce mortality due to fire.

Full textAbstract:
The hypoxic zone in the Gulf of Mexico is a symptom of a greater problem of nutrient loss to streams across the American Midwest. The United States Environmental Protection Agency (EPA) has responded to the problem by requiring states along the Mississippi River to develop nutrient reduction strategies and implement practices that reduce nutrient loss. The state of Iowa developed their strategy and formed the Iowa Nutrient Research Center (INRC) to study the most effective conservation practices and policies. This thesis is conducted as part of the INRC and is focused on the development of a hydrologic and water quality model of the Cedar Creek watershed in southeastern Iowa.
The Cedar Creek hydrologic and water quality model was created using MIKE SHE, a coupled surface/subsurface modeling software. The model was calibrated using real-time streamflow and water quality measurements taken within the watershed. Several water quality scenarios were tested in order to determine the most effective ways to simulate nitrate concentration within the MIKE SHE framework. The results of this thesis will guide future hydrologic and water quality modeling in agricultural watersheds and serve as a demonstration of the ways to simulate nutrient transport within the landscape.

Full textAbstract:
The goal is to perform heat measurements examine of selected roofing material samples. Those roofing materials are asphalt shingles, ceramics, and cedar. It’s important to understand the concept of heat transfer, which consists of conduction, convection, and radiation. Research work was reviewed on different infrared devices to see which one would be suitable for conducting my experiment. In this experiment, the main focus was on a specific property of radiation. That property is the emissivity, which is the amount of heat a material is able to radiate compared to a blackbody. An infrared measuring device, such as the infrared camera was used to determine the emissivity of each sample by using a measurement formula consisting of certain equations. These equations account for the emissivity, transmittance of heat through the atmosphere and temperatures of the samples, atmosphere and background. The experiment verifies how reasonable the data is compared to values in the emissivity table. A blackbody method such as electrical black tape was applied to help generate the correct data. With this data obtained, the emissivity was examined to understand what factors and parameters affect this property of the materials. This experiment was conducted using a suitable heat source to heat up the material samples to high temperature. The measurements were taken during the experiment and displayed by the IR camera. The IR images show the behavior of surface temperatures being distributed throughout the different materials. The main challenge was to determine the most accurate emissivity values for all material samples. The results obtained by the IR camera were displayed in figures and tables at different distances, which was between the heap lamp and materials. The materials exhibited different behaviors in temperature and emissivity at certain distances. The emissivity of each material varied with different temperatures. The results led to suggestions of certain materials that could be beneficial and disadvantageous in energy and cost savings during cold and hot seasons of the year. Also this led to some uncertainties in the data generated. Overall, this can support in exploring other ideas to increase energy and cost saving consistently during both season by using a material that can change its color and density based on a high or low temperature.

Western hemlock (Tsuga heterophylla (Raf.) Sarg.) and
western red cedar (Thuja plicata Donn) seedlings from four
dormancy induction treatment(s) (DIT) (i.e. long-day dry,
long-day wet, short-day dry, and short-day wet) were planted
on a high available soil moisture field site in British
Columbia and monitored for physiological response and
morphological development over the first growing season.
Stomatal conductance (gwv) and net photosynthesis (Pn) were
recorded over an environmental matrix of photosynthetically
active radiation (PAR) (0 - 2.2 mmol m⁻² s⁻¹ ) and vapour pressure deficit (VPD) (0 - 2.5 or 4.0 kPa) on both first year grown and fully developed second year foliage. To compare stocktypes, physiological data were collected and analyzed in the following ways: (1) replicated data at stable environmental conditions once a month, (2) physiological response to one increasing environmental variable using boundary line analysis, and (3) physiological response surface to two simultaneously changing environmental variables.
For western hemlock first year needles, short-day DIT had a higher gwv response to both increasing VPD and PAR. Both short-day and moisture stressed DIT improved Pn response to PAR, and the combination had the highest response. Short-day DIT seedlings initially were smaller, shorter, had a better seedling water balance ratio and lower shoot to root ratio. Short-day second year needles showed a slightly higher gwv response to both increasing VPD and PAR as compared to long-day seedlings; however, they showed no treatment differences for Pn versus PAR. All stocktypes had similar final morphological parameter values.
For western red cedar first year foliage, moisture stressed DIT seedlings had greater Pn response to increasing PAR and VPD. Also, moisture stressed seedlings gwv response to increasing VPD and PAR was higher when compared to its' non moisture stressed daylength counterpart. The long-day wet seedlings initially had a larger root and shoot system as compared to the other stocktypes. Second year foliage exhibited no treatment differences for gwv and Pn response to PAR ' and VPD. All stocktypes had similar final morphological parameter values.
Attempts to test stocktypes at stable environmental conditions proved, at times, difficult. Potentially large measurement variation due to atmospheric environmental changes, and not stocktype effect, could result. Boundary line analysis, when used correctly and with sufficient data, offers a good stocktype assessment method which enables the isolation of a physiological response to one environmental variable. Three dimensional surface response technique was required to provide a clear conceptual representation of two primary environmental variables' influence on seedling physiological response.Forestry, Faculty of

Our knowledge of climate variability in the densely populated Northeastern United States is limited to instrumental data of the last century. Most regional paleoclimate proxies reflect a mix of climate responses, which makes reconstructing historical climate a challenge. Here we analyze tree-ring chronologies from Atlantic white cedar (Chamaecyparis thyoides) as a potential regional paleotemperature proxy. We evaluate our tree-ring network for spatiotemporal climate signal strength and reconstruction skill across New England. Atlantic white cedar sites in the northern section of the species' range exhibit positive significant annual growth relationships with local and regional temperatures. Chronologies constructed from northern sites yield skillful reconstructions of temperature that reproduce centennial, multidecadal, and interannual variability in the instrumental record, providing a novel paleotemperature record for New England.

Full textAbstract:
The Convention of the Elimination of all forms of Discrimination Against Women, CEDAW, was approved by the UN general assembly in 1979 and Sweden was the first country to ratify it in 1980. This thesis investigates, firstly, the importance of CEDAW on Swedish legislation and on sentences passed by Swedish courts, and secondly the significance of the fact that the influence from CEDAW has been based on an assertation of existing norms and not on a transformation or incorporation. Finally this thesis examines if CEDAW is followed. It is only the workplace that is analysed and the focus is on recruitment and wages. CEDAW has little or no importance for Swedish courts of law or their sentences. Since the incorporation of CEDAW is in agreement with earlier established norms it cannot be in force in Swedish courts or within public authorities but is only indirectly in force as a complement to national law. To be in force CEDAW must be implemented by incorporation or transformation. The Swedish court system does not violate CEDAW, but it does not follow the convention either and, even if the result may be the same, this should be considered a discrepancy.

Full textAbstract:
Yellow-cedar (Chamaecyparis nootkatensis) is currently undergoing a dramatic decline in western North America, with concentrated areas of decline located in southeast Alaska and coastal British Columbia. Recent research suggests that a shift in climate is responsible for the decline and a working hypothesis concerning the role of climate and site specific factors has been proposed. The main objective of this research was to contribute to the understanding of the yellow-cedar decline phenomenon by examining the spatial pattern of the decline and assessing the relations with topographic variables in coastal British Columbia.
The research questions were addressed through a combination of remote sensing and Geographic Information System (GIS) techniques. Sample points were distributed across the landscape according to a stratified sampling scheme and the presence/absence of decline at each point was determined using a forest cover dataset and aerial photograph interpretation. Spatial patterns of topographic factors (e.g. elevation, slope, aspect) were derived from a 25 m digital elevation model of the province. To assess the strength of relations between the distribution of decline and the various environmental predictors, logistic regression and decision-tree models were applied. The lasso technique was used to select a significant set of coefficients and the selection was then validated through bootstrap analysis. Model results indicated that low elevation sites close to the coast, which are more exposed and have more variation in elevation, are more likely to show evidence of decline. The logistic model fit the data well (Nagelkerke R² = 0.846, Hosmer-Le Cessie omnibus test failed to find any evidence of lack of fit) and had high predictive accuracy (AUC = 0.98).
The topographic variables identified by the model influence degree of soil saturation, temperatures and snowpack presence in a forest stand, supporting the proposed associations in the current decline hypothesis. The analysis also highlighted the utility of the lasso logistic model for selecting significant variables and mapping high risk areas for decline. Knowledge of the determinants of the spatial pattern of decline will improve predictability and provide critical information for the conservation and management of yellow-cedar.

Full textAbstract:
This research explores the relationship between the cognitive variables perceived risks, perceived barriers, perceived self-efficacy, and perceived hazard experience with farmer support for adaptation and the agreement between farmer perceptions with observed climate conditions of drought and excess precipitation. Climate conditions were evaluated using monthly Standardized Precipitation-Evapotranspiration Index (SPEI) values from 1950 to 2014. The remaining variables were measured using a closed ended survey of corn and soybean farmers (N =276) in the Iowa-Cedar Watershed. The relationships were evaluated using Spearman’s Rank Order Correlation (), frequency distributions, and probability analysis. Perceived barriers were found to be a significant predictor of support for adaptation. Transformational adaptations were less supported by farmers than incremental adaptations. Farmers expressed more concern for finances than any other risks or barrier. The majority of farmers reported low to moderate risks to drought and precipitation with high efficacy to cope to future impacts. Lastly, climate conditions indicate that there were more frequent and extreme precipitation events than drought events and that farmer perceptions of climate are consistent with observed climate conditions. However, while climate change projections indicate increased weather extremes in the future, farmers perceive no change in risks. It is unclear whether or not farmers are actually equipped to handle future threats to their crops. Future research should address this problem by conducting a longitudinal study to observe farmers’ perception prior to and after experiencing extreme events.

As Ciências da Administração desenvolvem-se a partir do período monopolista do capital, nos primórdios do século XX. Contudo, durante muitos anos a produção acadêmica neste campo do conhecimento desconsiderou a negação aos postulados de supremacia técnica e ideológica ao quais as origens da Administração vinculam-se. No presente trabalho, me esforço em discutir a resistência aos padrões hegemônicos de organização do trabalho em uma organização cultural cujo objetivo não tem ligação com o mercado, mas com a luta revolucionária cubana: a Associação Cultural Jose Martí de Santa Catarina. A organização é analisada em suas práticas organizativas e, como o foco é resistência, busco analisar a resistência como um processo histórico de recusa não a uma forma ou prática memeticamente dominante, mas econômica e politicamente dominante em um tempo histórico cujos imperativos de reprodução do capital se estendem para além da empresa (típica forma de organização do trabalho da sociedade capitalista) por uma necessidade do próprio capital. Necessidade esta que é imposta aos demais seres humanos, uma vez que a produção da vida humana está obrigada, nessa sociedade específica, a uma mediação alienada de segunda ordem. Assim, para tentar apreender minimamente o processo de resistência e luta da Jose Martí pela solidariedade, amizade e autodeterminação dos povos, tive de decompor o conceito de resistência e busquei o que seriam seus elementos constitutivos, a saber: (a) a contra-hegemonia e a resistência; (b) a ascensão do capitalismo e a postulação científica das formas e práticas de gestão (a Administração); (c) a gestão como forma de subsunção de um tipo específico de trabalho; (d) o tipo específico de trabalho como uma manifestação histórica (e, portanto, mutável, não perene, não determinada naturalmente), logo construída pelos seres humanos; (e) o trabalho como algo mais que o trabalho no capitalismo; (f) o capitalismo como um modo de produção orgânico de domínio do capital; (g) o capital como uma relação social histórica de dominação estrutural do trabalho; (h) o trabalho como fenômeno originário do ser social; (i) o ser social não como, simplesmente, um ser diferente dos demais, mas como um ser ontológico, parte da natureza, que, assim como a vida orgânica é precedida pelas formas de organização inorgânica da matéria, e que, assim como a manifestação orgânica já surge com a capacidade de reprodução, o ser social é precedido por ambas manifestações e já surge com a capacidade ontológica de trabalhar. Após, retomo a discussão sobre resistência, me atendo ao caso específico e em sua relação com essa totalidade.

Full textAbstract:
Cedrus is a long-lived forest tree whose extant distribution is limited to a disjunct occurrence at the southern margin of the wide expansion range of its family Pinaceae. Its taxonomy is marked with conflicting inferences. The position of Cedrus within Pinaceae is unresolved between the major subfamily groupings. The infrageneric classification of Cedrus taxa, which is based on indistinct phenotypic characters, remains highly controversial. Within its narrow geographical boundaries, Cedrus has long been, and is still, threatened with a diversity of degrading pressures that raise questions on the viability of the dispersed remnant populations. The unsettled taxonomic dispute, compounded with gaps and uncertainties in the information available on the genus, impede potential efforts toward the conservation and sustainable management of this ancient heritage. This study employed molecular systematics to establish a better understanding of the phylogenetic relationships of Cedrus at the different organizational levels from genus to species and populations. The phylogeny of Pinaceae, reconstructed from chloroplast DNA sequences, establishes Cedrus as a monophylum and resolves its position as sister to the rest of the Pinaceae genera. A DNA-based phylogeny of the interrelationships within Cedrus delimits five evolutionary units which are recognized as species, emphasizing the significance of their geographical disjunction. The evolutionary sequence of these units defines an east-west migration trend from the Himalayas toward the Mediterranean. At the population level, fingerprinting of the genetic diversity in the remnant Cedrus isolates of Lebanon infers a substantial level of diversity distributed within populations with no indication of interpopulation divergence. These findings are instrumental at defining the future conservation of Cedrus as a genetic resource

The present study aimed to evaluate some limiting factors to the growth of Toona ciliata M. Roem. var. australis (Australian red cedar). In chapter I, it was evaluated the growth of Toona ciliata seedlings inoculated with arbuscular mycorrhizae fungi (FMAs), Acaulospora laevis, A. morrowiae, Entrophospora colombiana, E. contigua, Gigaspora margarita, Glomus clarum, Scutellospora calospora, S. gilmorei, S. heterogama e S. pellucida. In chapter II, it was evaluated the contents and accumulations of nutrients in Australian red cedar seedlings, submitted the complete solution, diluted solution 1/2 and 1/4. In chapter III, it was verified the symptoms of macronutrients deficiency, nutrients contents and accumulations in the Australian red cedar plants submitted the complete solution with omission of N, P, K, Ca and Mg. Chapter IV, it was observed the reply of the species the aluminum presence, using treatments with complete solution diluted the 1/4 with addition of 0, 5 and 20 mg. L-1 de Al. Between AMF tested, A. morrowiae, E. contigua e S. pellucida were most efficient in promoting the accumulation of dry weight of aerial part, development of the area leaf and phosphorous content on leaf in Toona ciliata seedlings, beyond presenting the biggest densities of esporos.50 cm-3 of substrate. And the biggest incidence of mycorrhizae settling in Toona ciliata seedlings was gotten with the species S. pellucida. The behavior of the species in reply to the use of nutritional solutions complete and diluted 1/2 and 1/4, showed that the biggest increment in height, diameter and dry weight had occurred in plants submitted at diluted solution the 1/4. The macronutrients contents and accumulations in Australian red cedar plants presented the following decreasing order: N > K > Ca > P > Mg. With regard to nutritional deficiency it verified that the omission of K was the one that more affected the development of the plant in height. The limitation in the increment stem diameter of the plants occurred in all the treatments, with exception of the complete solution. The production of total weight dry of the plants was affected in all the treatments with omission of nutrients, in according the following decreasing order: Complete Solution > - P > - Mg > - N > - K > - Ca. The initial growth of Toona ciliata seedlings was affected by the omission of all the macronutrients, having been the similar symptoms with the symptoms of other species of the same family. The immediate damages most intense and had been observed in the omission of K and Ca. Thus, the Toona ciliata species demonstrated to be demanding in macronutrients in the following decreasing order: K > N > Mg > Ca > P. The reply of the species the aluminum presence demonstrated that the growth, nutrient content and accumulation in Australian red cedar plants were stimulated in the presence of 5mg.L-1 of aluminum. The addition of 20 mg.L-1 de Al reduced the growth of the plants and macronutrients accumulation, in the following decreasing order: Ca > Mg > N > P > K. The visual symptoms of fitotoxicity had been typical to this element, beyound of the leaf with intense green coloration progressing for the yellow; the leaves oldest had progressed for yellow-brown, the edges to the limb center; and curving of new leaves.
O presente trabalho teve como objetivo avaliar alguns fatores limitantes ao crescimento de Toona ciliata M. Roem. var. australis (cedro-australiano). No cap?tulo I, avaliou-se o crescimento de mudas de cedro-australiano inoculadas com fungos micorr?zicos arbusculares (FMAs), Acaulospora laevis, A. morrowiae, Entrophospora colombiana, E. contigua, Gigaspora margarita, Glomus clarum, Scutellospora calospora, S. gilmorei, S. heterogama e S. pellucida. No cap?tulo II, foram avaliados os teores e ac?mulos de nutrientes em mudas de cedro-australiano, submetidas ? solu??o nutritiva de Hoagland & Arnon modificada, completa, dilu?da a 1/2 e a 1/4 de for?a i?nica. No cap?tulo III, verificou-se os sintomas de defici?ncia de macronutrientes, teores e ac?mulos de nutrientes nas plantas de cedroaustraliano crescidas em solu??o nutritiva com omiss?o de N, P, K, Ca e Mg. No Cap?tulo IV, observou-se a resposta da esp?cie estudada na presen?a de alum?nio, empregando tratamentos com solu??o nutritiva dilu?da a 1/4 com adi??o de 5 e 20 mg.L-1 de Al, al?m de uma testemunha Entre os fungos micorr?zicos arbusculares testados, A. morrowiae, E. contigua e S. pellucida foram os mais eficientes em promover o ac?mulo de mat?ria seca da parte a?rea, desenvolvimento da ?rea foliar e teor de f?sforo foliar em mudas de Toona ciliata, al?m de apresentarem as maiores densidades de esporos por 50 cm3 de substrato. A maior coloniza??o micorr?zica em mudas de Toona ciliata foi obtida com a esp?cie f?ngica S. pellucida. O comportamento da esp?cie em resposta ao emprego de solu??es nutritivas completas, dilu?da a 1/2 e 1/4, mostrou que o maior incremento em altura, di?metro e mat?ria seca ocorreram em plantas submetidas ? solu??o dilu?da a 1/4. Os teores e ac?mulos de macronutrientes em plantas de cedro-australiano seguiram a seguinte ordem decrescente: N > K > Ca > P > Mg. Com rela??o ? defici?ncia nutricional, verificou-se que a omiss?o de K foi a que mais afetou o crescimento em altura. A limita??o no crescimento em di?metro do coleto das plantas ocorreu em todos os tratamentos, com exce??o da solu??o de Hoagland & Arnon. A produ??o de massa seca total das plantas foi afetada em todos os tratamentos com omiss?o de nutrientes, obedecendo ? seguinte ordem decrescente: Completo> -P > -Mg > -N > -K > -Ca. O crescimento inicial de mudas de Toona ciliata ? afetado pela omiss?o de todos os macronutrientes, sendo os sintomas semelhantes com os sintomas de outras esp?cies da mesma fam?lia. Os danos mais intensos e imediatos foram observados na omiss?o de K e Ca. Assim, a esp?cie Toona ciliata demonstrou ser exigente em macronutrientes na seguinte ordem decrescente: K > N > Mg > Ca > P. A resposta da esp?cie ? presen?a de alum?nio demonstrou que o crescimento, teor e ac?mulo de nutrientes em plantas de cedro-australiano foram estimulados na presen?a de 5mg.L-1 de alum?nio. A adi??o de 20 mg.L-1 de Al reduziu o crescimento das plantas e o ac?mulo de macronutrientes, na seguinte ordem decrescente: Ca > Mg > N > P > K. Os sintomas visuais de fitotoxidez associados ? dose de 20 mg.L-1 de Al foram t?picos da toxidez a este elemento, al?m das folhas apresentarem colora??o verde intensa progredindo para o amarelecimento; com a acentua??o dos sintomas, as folhas mais velhas progrediram para amarelo-castanho, dos bordos para o centro do limbo e enrolamento ou encurvamento de folhas novas.

Os movimentos de massa no Brasil geram inúmeros problemas sociais e econômicos. Logo, é imprescindível compreender os mecanismos desses fenômenos e a influência de fatores externos na sua deflagração, contribuindo, dessa forma, com subsídios de prevenção eficazes. Neste contexto, o uso de modelos matemáticos, baseados em conceitos hidrológicos e de estabilidade de encosta, aliado ao mapeamento geotécnico e a técnicas de sensoriamento remoto, compõe uma metodologia pertinente. A presente pesquisa objetiva identificar áreas suscetíveis a escorregamentos translacionais, utilizando o modelo computacional SHALSTAB (Shallow Landsliding Stability Model) e caracterizá-las quanto a parâmetros geotécnicos, topográficos (altitude e declividade) e de uso e ocupação do solo. A área de estudos é a bacia hidrográfica do Rio Cunha, situada no município de Rio dos Cedros/SC e pertencente à região do médio vale do Itajaí, uma das regiões mais atingida pelos desastres hidrológicos de novembro de 2008. A metodologia consistiu no mapeamento das cicatrizes resultantes dos movimentos ocorridos na área de estudos, na determinação em campo e em laboratório de parâmetros do solo (físicos, de resistência e espessura) e na elaboração de mapas temáticos: modelo digital de elevação e seus derivados (declividade e área de contribuição), mapa de uso e ocupação do solo e mapa geotécnico preliminar. Na modelagem de áreas instáveis foram realizadas 48 simulações com diferentes combinações dos parâmetros do solo (densidade, coesão efetiva, ângulo de atrito efetivo e espessura), dentre as quais definiu-se aquela que melhor representa o fenômeno na área em estudo com base nas cicatrizes dos movimentos de 2008. As áreas de instabilidade definidas pelo modelo, bem como as cicatrizes dos movimentos foram confrontadas com os mapas temáticos para a sua caracterização, contribuindo para a elaboração de um banco de dados. Como resultado final tem-se um mapa de áreas suscetíveis a escorregamentos translacionais para a bacia em estudo, que, aliado ao banco de dados das áreas de instabilidade geram subsídios para atuar na identificação de áreas sujeitas a movimentos de massa, auxiliando no planejamento preliminar de uso e ocupação do solo da área. A metodologia empregada neste estudo pode ser aplicada por órgãos públicos para a redução de desastres relacionados a movimentos de massa, atuando no planejamento de ações preventivas.
Abstract : Mass movements in Brazil generate numerous social and economic problems. Therefore, it is essential to understand the mechanism of these phenomena and the influence of external factors in their generation, contributing thus to effective prevention grants. In this context, the use of mathematical models, based on concepts hydrological and slope stability, combined with geotechnical mapping and remote sensing techniques, composing a relevant methodology. This research aims to identify areas susceptible to landslide using the computational model SHALSTAB (Shallow Landsliding Stability Model) and define them as geotechnical, topographic parameters (altitude and slope) and the use and occupation of land. The study is the watershed of the Rio Cunha, in the municipality of Rio dos Cedros/SC and it belongs to the middle valley of Itajaí, one of the regions most devastaded by hydrological disasters of November 2008. The methodology consisted in mapping the consequences resulting from movements in the study area, both in the field and in laboratory parameters (physical, strength and thickness) soil and preparation of thematic maps: digital elevation model and derivates (slope and contributing area), map of use, land use map and geotechnical preliminary map. on modeling of unstable areas, 48 simulations were done with different combinations of soil parameters (density, effective cohesion, effective angle of friction and thickness) in wich, the best one that better represents this phenomenon is defined based on movements of 2008. Areas of instability defined by the model, as well as the sears of the movements were confronted with thematic maps for its characterization, contributing to the development of a database. As a result, there is a map of susceptible areas to landslides for watershed study. Also, there is a database of areas of instability that generate subsidie in order to identify susceptible areas to mass movements, helping in a preliminary planning of use and occupation of the area. The methodology used in this study can be applied by public agencies for disaster reduction related to mass movements, performing preventive action plannings.

Full textAbstract:
Due to many favourable characteristics such as a moist and mild climate year round, the absence of fire or a major insect infestation and disease, the coastal coniferous forests of northern Vancouver Island are among the most productive forests in British Columbia. However, the productivity rates can vary in a mosaic pattern of two very distinctive forest types: low-productivity “CH” and medium-productivity “HA”. In 1987-88 a trial was established to analyse growth effects of fertilization on western red cedar (Thuja plicata Donn ex D. Don) and western hemlock (Tsuga heterophylla (Raf.) Sarg.) at these two different sites. Previous projects measured the height and the DBH after 10 and 15 growing seasons, and have been recently re-measured again after 22 years since establishment. Fertilizer was applied three times after planting; stand density was established at: 500, 1500 and 2500 stems/ha. Fertilization significantly increased the height and volume of both species at all treatment. Depending on the site fertility and treatment used, the stand volume of fertilized red cedar increased from 123% to 351% and fertilized hemlock volume increased from 106% to 2190% compared to the non-fertilized counterparts. In most cases, higher densities had much greater volume per hectare than lower density stands; however, density caused a significant decrease in the average height of both species at CH sites. Biomass and carbon content were also estimated in this study. Results indicated a positive growth response of total biomass generated by fertilization. CH sites have shown the best increment response to fertilization; however, averages were still low if compared to HA sites. Overall, the best treatments were found to be high density fertilized hemlock stands on HA sites. This treatment not only had the greatest height, volume and biomass, but was also the most efficient for C capture. After 22 growing seasons, the results of this research reinforces the idea that fertilization is a reliable and effective tool to increase nutrient availability and productivity of these forests; it suggests that the focus of silvicultural treatments such as fertilization and increased stand density should be directed mostly towards the more productive HA sites.

Full textAbstract:
An exploratory analysis of the trihalomethane (THM) and haloacetic acid (HAA) formation potential (FP) of Cedar Lake in order to produce formation potential curves for both THM and HAA; determine the THMFP and rate constant and compare to previous studies on Cedar Lake; and develop modeling for the formation potential loss of HAA from laboratory analysis of the raw lake water. While extensive modeling approaches have been explored for THM formation on different water sources, not many have been applied to the reservoir that supplies water to the Carbondale Water Treatment Plant and even fewer have explored the formation and modeling of HAA. Data for this study was obtained through laboratory experiment by applying bleach as a substitute for free chlorine to raw water samples obtained from Cedar Lake and quenching the samples at specific time steps to stop the reaction. Samples were then analyzed for THM content using standard method EPA 524.2R4.1 and HAA content using standard method EPA 552.2. The observed peak formation was 641.2701 µg/L for THM and 426.8 µg/L for HAA, but modeling fitted to the laboratory results indicated that a lower FP provided a better fitting of the data. A detailed analysis of the formed THM and HAA compounds indicated that a model produced for each compound resulted in more appropriate fitting by being able to account for the differing reaction rates and limiting factors of each reaction.

Yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach) forests of coastal British Columbia
are apparently experiencing decline in a manner similar to that observed in southeastern Alaska. In this pilot study, we collect tree-ring data from live and standing dead yellow-cedar trees from four declining sites on the North Coast of British Columbia. We use this data to compare growth patterns at our sites to those of yellow-cedar trees at non-declining and declining sites in southwestern British Columbia and southeastern Alaska and, in addition, to assess the possibility of reconstructing yellow-cedar population dynamics in declining stands using dendrochronology. We found coherent growth patterns (i.e. marker years and periods of suppression) among yellow-cedar chronologies from non-declining and declining sites across a broad geographic range as well as unique growth patterns between our chronologies from declining sites and those from declining sites in nearby Alaska. Using outer-ring dates of increment cores, we were able to estimate time since death of decade- to century-old standing
dead yellow-cedar trees, although the precision of the estimates was influenced by partial cambial mortality and erosion of outer rings. Our results provide baseline dendrochronological information that will be useful for planning future studies that assess growth-climate relations and reconstruct the long-term population dynamics of yellow-cedar in declining stands.

Full textAbstract:
This doctoral project focuses on the effectiveness of Relational Spirituality training administered to the direct support professionals at Cedar Lake Lodge, an intermediate care facility for adults with severe intellectual and developmental disabilities. The effectiveness was tested through administration of a survey prior to and following a professional training session offered by the researcher. The results seem to demonstrate an increase in spiritual integration for direct support professionals who participated. The reframing of spiritual life supports as an element of recognizing the individuality of each person supported at Cedar Lake Lodge seemed to have a positive effect on professionals of various age, religious, and cultural affiliations. The expanded perspective of spiritual support holds the potential for cultivating rich, person centered care that is mutually beneficial to the people offering and receiving care in the intermediate care facility setting.
