Cadmium effects on vegetables : production, physiology and biochemistry

Jinadasa, N., University of Western Sydney, Hawkesbury, Faculty of Science, Technology and Agriculture, School of Horticulture January 1998 (has links)
Cadmium (Cd) is absorbed through the lungs and the digestive tract; however, for most human non-smokers, the major route of Cd entry into the body is by ingestion. Perhaps 5% of ingested Cd is absorbed and once absorbed, Cd accumulates mostly in the liver and kidneys, where it can cause a variety of health problems. This applies equally to grazing stock. The major entry point of Cd into the food chain is therefore uptakes of traces of Cd by crop plants. This thesis focuses on Cd in vegetables. The study was conducted in an Australian context, where geogenic Cd contributions to soils are typically low. Most of the Cd in soils on Australian vegetable farms originates from materials added to boost crop production. Phosphate fertilisers were and remain the dominant Cd source. Most Australian soils are P-deficient and high rates of P fertiliser are essential for successful vegetable cropping. The P fertilisers used throughout Australia were formerly made from guano deposits mined on Pacific Islands. These contained high percentages of Cd. Current rock sources contain lower Cd concentrations. Studies showed that all the vegetable samples which contained excessive Cd concentrations were leafy vegetables, including cabbage, lettuce, silverbeet, parsley and bok choy. Cadmium impaired photosynthesis; reduced dry weight of the whole plant; slowed leaf elongation rate; decreased the length of fully expanded leaves; slowed the rate at which new leaves appeared; and altered foliar concentrations of Zn, Mn, Cu, Ca and S. These profound changes affected all parts of the plant; consequently, Cd did not affect the proportion of dry weight partitioned to the roots, stems and leaves. / Doctor of Philosophy (PhD)

Real-Time Communication over Broadcast Networks

Forss, Jonas January 1999 (has links)
<p>Today the utilization of all kind of multimedia services in networks increases and due to this demand for real-time communication gets higher for every day. One of the most common protocols used today is Ethernet. It is of interest to find real-time protocols that are useful together with already existing protocols since it is expensive to rebuild the network infrastructure. Several new protocols have been proposed to solve the upcoming problems.</p><p>The objective of this project is to make an inventory and a comparison between Ethernet and these new protocols. During this project four different protocols capability to fulfill the demands for real-time communication have been studied and compared with Ethernet. Three of the protocols are built on the same basic technique as Ethernet and these are PCSMA, CSMA-DCR and DOD-CSMA-CD. The fourth protocol is ATM and it transmits in a different way over communication networks.</p><p>The analysis of this project is pointing out advantages, similarities and differences between the protocols from a real-time perspective. All four protocols are more suitable for real-time requirements than Ethernet.</p>

Détermination simultanée de la mise au point et de la dose d'un équipement de micro-lithographie optique / Simultaneous determination of focal plane and energy exposition of optical microlithography equipment

Spaziani, Nicolas 07 November 2012 (has links)
Les dimensions critiques des circuits intégrés diminuent continuellement au coursdes ans selon la loi de Moore. Les valeurs typiques sont aujourd’hui de 28nm,et seront de 22nm dans 18 mois. La photo-lithographie optique demeure encore latechnique la plus économique pour la production de masse. L’ouverture numériquedes objectifs atteint 1.30, grâce à l’introduction d’eau entre la lentille et la plaquette.La conséquence directe de ces grandes ouvertures est la réduction de la profondeurde champs de l’ordre d’une centaine de nanomètres. Le procédé photo-lithographiqueperdant de la latitude, le contrôle dimensionnel intra-cellule devient une nécessité.La variation dimensionnelle provient au premier ordre à la fois de la variation duplan focal dans le champ image, et aussi de la non uniformité de l’illumination duréticule. Pour contrôler cette variation, une boucle de régulation a été mise en placepour ajuster uniquement l’énergie des lots de production. On corrige ainsi de fait unmauvais focus par une compensation en énergie.Pour ne pas altérer l’image dans la résine, il est important de pouvoir dissocierles deux effets et adresser les causes de dégradation de l’image séparément. Le sujetde cette thèse est précisément de trouver un moyen de décorréler les deux paramètresaffectant l’uniformité de la dimension critique. L’idée principale est de trouver à lafois les motifs et les modèles théoriques pouvant conduire à discriminer des imagesselon leur sensibilité, soit au focus, soit à la dose / Following the ITRS roadmap, the critical dimension of the circuits are continuouslynarrowing. Optical Lithography still remains the cheapest way forintegrated circuits mass production. If the resists properties and the exposure wavelengthreduction had an important contribution to this result, the lens numericalaperture increase had a decisive impact. The numerical aperture is currently reaching1,30 thanks to the usage of water as immersion fluid between the lens andthe wafer. Future lens are targeting in a near future a 1,70 numerical aperture withimmersion fluids at higher refractive index. A direct consequence of these wider numericalaperture’s is the reduction of the depth of focus to few tens of nanometers,reducing the process windows and then the integrated circuits manufacturability. Inaddition the pure numerical aperture effect on focus, off axis illumination is leadingto amplify the reticle critical dimension variations, and the intrafield focus controlbecomes more and more crucial.The last scanner generation provides some tools to adjust the intrafield energy.As the two effects appear to compensate each of them critical dimension variation,it becomes very important to be able to dissociate the effect of one from the otherin order to select the most efficient mean to get the greater process windows. Moreover, the average value compensations must feed accurately the Run to Run feedback loop for the next exposed wafers.The purpose of this thesis is to find a way to un-correlate the various parametersaffecting the critical dimension uniformity. Some researchers tried to design specificfeatures whose shape modifications due to focus offset could be detected as an overlayerror measured by the appropriate tool, but the limitations seem to be actuallyreached. New tools, as scatterometers, could provide a more precise information.The desire output of this thesis would be to provide a methodology to allow an inline intrafield focus follow up for the future technologies at 20nm half pitch

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / O linfoma de Hodgkin (LH) à uma doenÃa linfoproliferativa maligna caracterizada morfologicamente pela presenÃa da cÃlula de Reed-Sternberg imersa em um substrato celular inflamatÃrio. A cÃlula RS à essencial para o diagnÃstico histopatolÃgico do LH, porÃm nÃo à patognomÃnica. A etiologia dessa doenÃa ainda à controversa, sendo provavelmente derivada de linfÃcitos B. A imunohistoquÃmica tem valor no diagnÃstico do LH e na distinÃÃo de outras desordens linfoproliferativas com cÃlulas RS sÃmile. Neste trabalho, tem-se como objetivo analisar os fatores envolvidos na refratariedade do linfoma de Hodgkin clÃssico (LHc) ao tratamento poliquimioterÃpico inicial com o esquema ABVD (Doxrubicina, Bleomicina, Vinblastina e Dacarbazina) em relaÃÃo aos marcadores imunolÃgicos CD 15 e CD 20, a dados epidemiolÃgicos dos pacientes e a exames complementares. TambÃm se tem como objetivo descrever a distribuiÃÃo dos casos de acordo com as variÃveis de sexo, idade, subtipo histolÃgico, estÃdio clÃnico da doenÃa ao diagnÃstico e presenÃa de sintomas B; classificar os pacientes quanto à presenÃa dos marcadores imunolÃgicos CD 15, CD 20 e CD 30, alÃm de descrever a porcentagem de pacientes com infiltraÃÃo da medula Ãssea pelo linfoma, a porcentagem de pacientes refratÃrios ao tratamento inicial com o esquema ABVD e a porcentagem de recidiva do LHc. Este trabalho consiste em uma anÃlise estatÃstica retrospectiva e prospectiva dos pacientes com LHc com diagnÃstico histopatolÃgico firmado entre janeiro de 2000 e dezembro de 2004. A anÃlise foi retrospectiva de janeiro de 2000 a dezembro de 2003, e prospectiva de janeiro de 2004 a dezembro de 2005, quando se parou o acompanhamento. Foram relacionados todos os 143 pacientes com diagnÃstico histopatolÃgico de LHc que iniciaram acompanhamento no Hospital UniversitÃrio Walter CantÃdio ou no Instituto do CÃncer do CearÃ, entre janeiro de 2000 e dezembro de 2004. Quarenta e seis pacientes foram excluÃdos da pesquisa. Um total de 97 pacientes permaneceu na pesquisa, sendo que destes 51 (52,6%) eram do sexo feminino e 46 pacientes (47,4%) eram do sexo masculino. A idade dos pacientes, ao diagnÃstico, variou de cinco anos a 76 anos, com mediana de 24 anos. Verificou-se apenas um pico de incidÃncia, o qual ocorreu entre 10 e 39 anos, com 78 pacientes (80,4%). Quanto ao subtipo histolÃgico, 65 pacientes (67,0%) eram portadores de LHc subtipo esclerose nodular, 21 pacientes (21,6%) apresentaram o subtipo celularidade mista, cinco pacientes (5,2%) apresentaram o subtipo rico em linfÃcitos, quatro pacientes (4,1%) apresentaram o subtipo depleÃÃo linfocÃtica e dois pacientes (2,1%) apresentaram o subtipo interfolicular. Sete pacientes (7,2%) apresentavam-se, ao diagnÃstico, em estÃdio clÃnico I da classificaÃÃo de Cotswolds, 43 pacientes (44,3%) apresentavam-se em estÃdio clÃnico II, 23 pacientes (23,7%) em estÃdio clÃnico III e 24 pacientes (24,8%) em estÃdio clÃnico IV. Sintomas B estavam presentes em 63 pacientes (64,9%) e ausentes em 34 pacientes (35,1%). Onze pacientes (11,3%) apresentaram infiltraÃÃo da medula Ãssea, ao diagnÃstico. A prevalÃncia do marcador CD 15 foi de 81,4% (79 pacientes), do CD 20 foi de 38,1% (37 pacientes) e do CD 30 foi de 100,0% (97 pacientes). Vinte e seis pacientes (26,8%) foram refratÃrios ao tratamento inicial com o esquema ABVD. Em seis (8,5%) dos 71 pacientes que atingiram remissÃo completa, ocorreu recidiva do linfoma. Treze pacientes (13,4%) foram a Ãbito durante o perÃodo de acompanhamento. O tempo de acompanhamento dos pacientes variou de um dia a 68 meses, com tempo mÃdio de acompanhamento igual a 32,5 meses. O tempo livre de doenÃa variou de zero a 60 meses, com mediana de 17,5 meses. A anÃlise do prognÃstico do LHc quanto a refratariedade ao tratamento inicial com o esquema poliquimioterÃpico ABVD foi realizada avaliando o sexo do paciente, a idade do paciente (<50 anos x &#8805;50 anos), a classificaÃÃo histolÃgica do linfoma, a positividade do marcador imunolÃgico CD 15 e do CD 20, o estÃdio clÃnico da doenÃa (graus I e II x graus III e IV), a presenÃa de sintomas B, o hematÃcrito (<42% x &#8805;42% em homens e <37% x &#8805;37% em mulheres), a hemoglobina (<13 mg/dL x &#8805;13 mg/dL em homens e <12 mg/dL x &#8805;12 mg/dL em mulheres), o tempo livre de doenÃa, a leucometria, a linfometria, a plaquetometria, o valor do VHS, o valor da glicemia sÃrica de jejum, o valor da fosfatase alcalina sÃrica, o valor do LDH sÃrico e a presenÃa de biÃpsia de medula Ãssea infiltrada pelo linfoma. Na anÃlise bivariada a presenÃa do CD 20 positivo, a presenÃa de sintomas B e a elevaÃÃo do valor da desidrogenase lÃtica apresentaram relaÃÃo de pior prognÃstico no que se refere a refratariedade, com p<0,05. Em uma anÃlise multivariada tipo regressÃo logÃstica envolvendo todas as variÃveis que apresentaram p<0,2 na anÃlise bivariada, a presenÃa do marcador CD 20 positivo aumentou a chance de refratariedade em 3,60 vezes e a presenÃa de sintomas B aumentou a chance de refratariedade em 5,41 vezes, refletindo um pior prognÃstico no que se refere a refratariedade do LHc ao tratamento inicial com o esquema ABVD.
