Alternative perceptions of reality: dyslexiaColgin, Clayton Shawn January 2009 (has links)
Master of Visual Arts / My MVA work, Alternative Perceptions of Reality: Dyslexia, revolves around dyslexia and ways in which dyslexic artists, like myself, represent reality in their art. I focus on how dyslexics perceive space and time, how this is represented in their work and how it manifests in my own work. The introduction describes why dyslexia is relevant to art, provides more detail on dyslexia itself and ways dyslexia can affect perception. Surrealism and Symbolism are discussed in order to draw parallels with dyslexic perception. Chapter 1 describes the influences on my own work, including dyslexia, primitive art and symbolism. The second chapter profiles two well known artists with dyslexia: Robert Rauschenberg and Pablo Picasso. I examine ways in which they represent space or reality and how dyslexic perception is apparent in their works. Similarly, in Chapter 3, I discuss the works of the contemporary dyslexic artists Terry A. Orchard and Katharine Dowson, including the results of interviews and surveys I conducted. Throughout this dissertation, I also discuss my own experience of dyslexia and how it is expressed through my paintings. In the conclusion, I discuss what I have learned about the work of myself and other dyslexic artists: How our paintings are a glimpse of alternative inner realities.

Tent isolation experiment in an advanced Scots pine seed orchardFredriksson, Emelie January 2013 (has links)
Pollen contamination is a severe problem in production breeding programs since it reduces the expected gain. In an attempt to solve this problem Skogforsk created an isolation experiment in the advanced Scots pine (Pinus sylvestris) seed orchard Västerhus in Västerbotten, Sweden. This experiment involves covering blocks of trees with a tent during the pollination period so that they only can mate with each other inside. To evaluate the effects of this tent treatment one tree from inside a tent with supplementary mass pollination (SMP) and one tree from the open control were chosen for this study. 48 seeds from each tree were sampled and genotypes at 9 microsatellite (SSR) loci. The likelihood and exclusion methods for paternity assignment were used to establish the fathers to these seeds. The results showed 0% contamination inside the tent and 4-8% outside in the control. The number of fathers contributed to the fertilization of the 48 seeds was 9 inside and 15 outside. The selfing rate was unexpectedly high, 10% inside the tent and 19% outside. The mating system inside the tent need to be further evaluated to fully understand what other effect the treatment has on the future progeny.

Faderskapsanalys av tallfrö från Västerhus fröplantage : Skillnaden i pollenkontaminering mellan öppen pollinering och pollinering inom ett avgränsat systemDahlberg, Helena January 2014 (has links)
In this study, pollen contamination (measured by the number of seeds pollinated by pollen not belonging to any of the clones on the seed orchard) is compared between open pollination and isolated pollination environments in a Scots pine (Pinus sylvestris) seed orchard called Västerhus, located outside Önsköldsvik. In this seed orchard a tent experiment is taking place. Skogforsk has built six large tents covering 12-14 trees with each tent. Fertilization patterns were compared between one tree in a tent with a supplementation of pollen from five clones not represented in the tent and another tree of the same clone subject to open pollination outside the tents. By using DNA markers the paternity was determined for 48 seeds from each tree. The results show a big difference in pollen contamination between the two trees. The tree inside the tent showed a contamination rate of 0% and the tree from the open pollination had a contamination rate of 20,5%. No difference was found in the numbers of different fathers although the selfing rate of 4,26% was higher in the tent than the selfing rate of 2,56% observed in the open pollination environment. These results match the results of other studies done on the same orchard pretty well and therefore tent isolation with a supplementary pollination can be a good way to reduce unwanted pollen contamination.

InfluÃncia do Uso de AgrotÃxicos na Qualidade dos Recursos HÃdricos da RegiÃo do PerÃmetro Irrigado Jaguaribe-Apodi/CE / Influence the Use of Pesticides in Water Quality in the Irrigated Region Jaguaribe-Apodi/CEMaria Aparecida Liberato Milhome 27 July 2011 (has links)
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / A regiÃo do Baixo Jaguaribe- CE consiste em uma das mais importantes Ãreas de fruticultura
irrigada do Estado CearÃ. Nos Ãltimos anos tem sido crescente o nÃmero de casos de cÃncer
nos municÃpios de Limoeiro do Norte e QuixerÃ, podendo està associado ao uso
indiscriminado de agrotÃxicos. A pesquisa teve como objetivo principal estudar a influÃncia
do uso de agrotÃxicos na contaminaÃÃo de Ãguas superficiais e subterrÃneas, utilizadas para
irrigaÃÃo e consumo humano, situadas nas proximidades do perÃmetro Irrigado Jaguaribe-
Apodi. Na primeira etapa, foi feito um levantamento de 37 princÃpios ativos aplicados pelos
agricultores nas principais culturas da regiÃo. Na segunda etapa foram utilizados modelos para
avaliar o potencial de contaminaÃÃo desses agrotÃxicos em Ãguas superficiais e subterrÃneas,
com base em suas propriedades fÃsico-quÃmicas. Foram aplicados mÃtodo de Screening da
EPA e Ãndice de GUS, para anÃlise de potencial de contaminaÃÃo em Ãguas subterrÃneas e
MÃtodo de GOSS, para Ãguas superficiais. AtravÃs dos resultados, foram identificados os
agrotÃxicos utilizados pelos agricultores da regiÃo do Baixo Jaguaribe com maior potencial de
contaminaÃÃo, dentre os quais foram selecionados Atrazina, Metil Paration, ClorpirifÃs,
Fenitrotion, TriazofÃs, Propiconazole, Difenoconazole e Azoxistrobina para monitoramento
das Ãguas. AlÃm disso, os agrotÃxicos Bentazona, Molinato, Pendimentalina e Malation
estabelecidos pelas legislaÃÃes, tambÃm foram monitorados. Na terceira etapa foi realizado o
desenvolvimento de mÃtodos cromatogrÃficos para anÃlise dos agrotÃxicos selecionados,
utilizando SPME/ GC-MS e SPE / HPLC-UV. ExtraÃÃo por SPME foi otimizada atravÃs
seleÃÃo da fibra, estudo do efeito do pH, tempo de equilÃbrio e variaÃÃo do volume de
amostra. Na quarta etapa foi realizado as coletas das amostras de Ãguas em 15 pontos mais
suscetÃveis a contaminaÃÃo, sendo 7 pontos do canal do DIJA e de reservatÃrios, e 8 poÃos.
De acordo com os resultados foram detectados os agrotÃxicos propiconazole, difenoconazole,
azoxistrobina, clorpirifÃs, metil paration, atrazina e triazofÃs, os quais pertencem a uma
variedade de grupos quÃmicos e diferentes tipos de uso. Os agrotÃxicos propiconazole e
difenoconazole apresentando os maiores nÃveis de concentraÃÃo detectados (3,84 - 10,14 e
0,33 - 6,93 μg/L, respectivamente). Cerca de 80% das amostras apresentaram nÃveis acima do
estabelecido pela comunidade europÃia, no entanto dentro dos padrÃes brasileiros. Apesar do
nÃvel de concentraÃÃo dos agrotÃxicos detectados està dentro do consumo diÃrio aceitÃvel em
Ãgua, isso nÃo deve ser tomado como uma justificativa para contaminaÃÃo descontrolada dos
recursos hÃdricos. Efeitos de toxicidade aguda e crÃnica, causados pelo uso itensivo de
agrotÃxico podem ser verificados ao homem e aos organismos do ecossistema. / The region of Baixo Jaguaribe-CE is considered one of the most important areas of irrigated
orcharding in Ceara state. In recent years there has been a growing number of cancer cases in
the cities of North Limoeiro and Quixerà and may associated with indiscriminate use of
pesticides. The research aimed to study the influence of pesticide use in the contamination of
surface and groundwater used for irrigation and human consumption, located in the vicinity of
irrigation projects in the region of Baixo Jaguaribe. The first step was a survey of 37 active
ingredients applied by farmers in major crop in the region. In the second stage models were
used to evaluate the potential for contamination of pesticides in surface water and
groundwater, based on their physicochemical properties. Screening method of EPA and GUS
index were applied for analysis of potential contamination to groundwater and Goss method
for surface waters. Through the results, we identified the pesticides used by farmers in the
Baixo Jaguaribe with greater potential for contamination, among which were selected
atrazine, methyl parathion, chlorpyrifos, fenitrothion, triazophos, propiconazole,
difenoconazol and azoxystrobin for water monitoring. In addition, pesticides bentazone,
molinate, malathion and pendimentalina established by legislation, were also monitored. The
third step was conducted to develop methods for chromatographic analysis of selected
pesticides using SPME / GC-MS and SPE / HPLC-UV. SPME procedure was optimized by
selection of fiber, studied the effect of pH, equilibrium time and variation of sample volume.
The fourth stage was carried to the sampling of water samples in 15 points more susceptible
to contamination (7 points Dija canal and reservoirs, and 8 wells) According to the results
detected the pesticide propiconazole, difenoconazole, azoxystrobin, chlorpyrifos, methyl
parathion, atrazine and triazophos, which belong to a variety of chemical groups and different
types of use. Pesticides propiconazole and difenoconazole showed the highest concentration
levels detected (3.84 to 10.14 and 0.33 to 6.93 μg/L, respectively). About 80% of the samples
had levels above the established by the European community, however within the Brazilian
standards. Despite the concentration level of pesticides detected is within the acceptable daily
intake of water, this should not be taken as an excuse for uncontrolled contamination of water
resources. Effects of acute and chronic toxicity caused by pesticide use can be observed in
humans and organisms in the ecosystem.

Radiant Energy Exchange Above and Within a Dwarf Apple OrchardSuckling, Philip 05 1900 (has links)
<p> The radiation balance of a dwarf apple orchard was evaluated.
Results compared favourably with those for a single apple tree in an
earlier investigation. Reflection, heating and longwave exchange
coefficients were analysed. </p> <p> Transmitted global radiation was measured with moving and
stationary sensors. Coefficients for the partitioning of incident global
radiation were calculated. A relationship between photosynthetically
active radiation and global radiation was established. Coefficients for
the partitioning of incident photosynthetically active radiation were
obtained and compared to the global radiation components. A problem
associated with the measurement of transmitted radiation is discussed
briefly. </p> / Thesis / Master of Science (MSc)
