Isolation of ABA Insensitive Mutants using a Sensitized ScreenNam, Eric Hyung-Uk 27 July 2010 (has links)
ABA insensitive mutants (abi1 - abi5) have been isolated in germination screens that use high concentrations of exogenous ABA, and this method is believed to be saturated. To overcome this problem, a sensitized screen that used much lower concentration of exogenous ABA was performed to isolate new ABA insensitive mutants. Some of the isolated mutants had defects in light or retrograde signalling. One particular mutant (18-11) developed long hypocotyls under normal light condition. Based on its response to blue, red and far-red light conditions, this mutant is likely a novel hy mutant. Genetic analysis revealed that while ABA insensitivity in this mutant is recessive, the long hypocotyl phenotype is dominant. Positional cloning is currently being carried out to identify the gene. Findings from this study supports that ABA signalling interacts with light signalling networks.

Den perfekta filmlystern : En kvalitativ studie i kopplingen mellan stereotyper och porträttering av hy i amerikanska filmer i high school-miljö.Eriksson, Sandra, Åström, Elias January 2018 (has links)
Imperfektioner i skådespelares hy upplever vi sällan visas inom film och medier relaterade till film. Många gånger i film tycks hy användas för att gestalta olika stereotyper. Kan detta leda till att ideal och fördomar stärks hos publiken? I denna uppsats har vi valt att undersöka detta genom att analysera filmer vars handling har en koppling till high school samt genom ett utförande av två fokusgrupper med filmstudenter som informanter. Utifrån dessa gick det tydligt att se hur den porträtteringen som ofta förekommer i film av personer med till exempel finnar hade fått informanterna att tänka mer negativt om sina egna finnar och sin hy. Det gick även att se att informanterna snabbt drog kopplingar mellan karaktärernas utseende och vilken stereotyp de tillhörde.

Logueo de alteración potásica y sericítica en el pórfido cuprífero de los sulfatos, Chile Central, usando el sistema HYLOGGER?Sánchez Villar, Sebastián Ignacio January 2017 (has links)
Geólogo / El Yacimiento Los Sulfatos (Anglo American), distrito Río Blanco - Los Bronces, es un depósito tipo pórfido cuprífero de clase mundial ubicado a 50 km al noreste de Santiago, Chile central. Presenta mineralización de cobre que corresponde a calcopirita y bornita principalmente el cual se aloja en varios cuerpos tipo pórfidos y brechas hidrotermales magmáticas, presentando texturas diseminadas y vetilleos intensos. La necesidad de encontrar los controles mineralizadores de alta ley y de generar una caracterización mineral de mena y ganga detallada y de alta resolución, motiva a buscar nuevas herramientas de caracterización mineral semi-cuantitativa e idealmente cuantitativa.
En el presente estudio se obtuvieron espectros de reflectancia infrarrojos para distintos tramos de sondajes, representativos de las alteraciones potásica y cuarzo sericita del yacimiento, en los rangos de longitud de onda NIR, SWIR y TIR mediante el sistema de logueo automático hiperespectral HyLogger3 , desarrollado por CSIRO. Estos espectros fueron analizados e interpretados mediante el software The Spectral Geologist (TSG ) utilizando el módulo The Spectral Assistant (TSA ).
Los resultados obtenidos por el análisis hiperespectral muestran como mineralogías predominantes: cuarzo, feldespato potásico (microclina, ortoclasa), albita, turmalina, muscovita (sericita), yeso (anhidrita), flogopita y clorita. Estos resultados fueron corroborados con otros métodos de caracterización mineral, como difracción de rayos X cuantitativa, caracterización macroscópica, petrografía y geoquímica multi-elemento. Utilizando esta información, se identificaron las asociaciones mineralógicas características para los tipos de alteraciones en estudio. Esto se realizó mediante comparación directa de los tramos, y por medio de la generación de un modelo de alteración utilizando el software Leapfrog®, el cual fue comparado con el modelo geológico conceptual ya existente del proyecto.
Se concluye que el sistema HyLogger y el software TSG, asociado a otros métodos de caracterización mineral, constituyen una herramienta rápida y eficaz para caracterización mineral y es un complemento para la modelación. Por otra parte, el valor y utilidad de los espectros obtenidos por HyLogger puede aumentar considerablemente dependiendo del análisis que se haga de los mismos. / Este trabajo ha sido financiado por Angloamerican

Partiendo de ibi: La traducción del antiguo adverbio pronominal enlas primeras Biblias romanceadas castellana e italianaa partir de la VulgataVazquez, Luis Fernando 01 June 2015 (has links) (PDF)
Usando el Corpus de la Biblia Medieval como herramienta principal, el presente trabajo explora el desaparecido adverbio pronominal y (hy, hi, i) en castellano a través de la comparación de la traducción del adverbio locativo ibi del latín al castellano e italiano usando la Vulgata, la Biblia prealfonsí y la Biblia del Malermi. Los resultados muestran que el adverbio pronominal en castellano no es el predilecto de la traducción y sin embargo es amplia y libremente usado en el texto castellano sin necesidad de tener un equivalente adverbial en latín. Dicha discrepancia se puede explicar considerando la ley Tobler-Mussafia que no le permite al adverbio pronominal introducir oraciones independientes como clítico. Sin embargo, es su flexibilidad como clítico la que le permite ocupar cualquier posición en el sintagma verbal. Dicha característica no la refleja el equivalente en italiano ivi, el cual tiende a comportarse más como adverbio. En la comparación de los tres textos, es el castellano el más leal a la sintaxis del latín en el uso del adverbio con respecto a su posición con el verbo.

Využití termovizní kamery pro měření teploty elektrických strojů / Utilization of infrared camera for temperature measurement of electrical machinesLíbal, Jan January 2009 (has links)
The master‘s thesis deals with utilization of infrared camera for temperature measurement of electrical machines. The first part describes non-contact temperature measuring, the second part describes principle of sensors that evaluate quantity of incident infrared radiation. In the next part there is termovision camera SAT-HY 6800 presented and the instructional manual for SAT Report computer programme created. This computer programme is used for analyzing of termovision pictures from the SAT-HY 6800 termovison camera. The chapter 7 describes temperature measuring of one-phase asynchronous motor type J22TO484. The chapter 8 describes temperature measuring of semiconductor components of EC motor G6 series. Both of these motors are produced by ATAS elektromotory Náchod a.s. The last part of the thesis describes creation of animation of one-phase asynchronous motor type J22TO455. The animation was created in 3ds Max computer programme.

Health for community dwelling older people : trends, inequalities, needs and care in rural VietnamVan Hoi, Le January 2011 (has links)
Background InVietnam, the proportion of people aged 60 and above has increased rapidly in recent decades. The majority live in rural areas where socioeconomic status is more disadvantaged than in urban areas.Vietnam’s economic status is improving but disparities in income and living conditions are widening between groups and regions. A consistent and emerging danger of communicable diseases and an increase of non-communicable diseases exist concurrently. The emigration of young people and the impact of other socioeconomic changes leave more elderly on their own and with less family support. Introduction of user fees and development of a private sector improve the coverage and quality of health care but increase household health expenditures and inequalities in health care. Life expectancy at birth has increased, but not much is known about changes during old age. There is a lack of evidence, particularly in rural settings, about health-related quality of life (HRQoL) among older people within the context of socioeconomic changes and health-sector reform. Knowledge of long-term elderly care needs in the community and the relevant models are still limited. To provide evidence for developing new policies and models of care, this thesis aimed to assess general health status, health care needs, and perspectives on future health care options for community-dwelling older people. Methods An abridged life table was used to estimate cohort life expectancies at old age from longitudinal data collected by FilaBavi DSS during 1999-2006. This covered 7,668 people aged 60 and above with 43,272 person-years. A 2007 cross-sectional survey was conducted among people aged 60 and over living in 2,240 households that were randomly selected from the FilaBavi DSS. Interviews used a structured questionnaire to assess HRQoL, daily care needs, and willingness to use and to pay for models of care. Participant and household socioeconomic characteristics were extracted from the 2007 DSS re-census. Differences in life expectancy are examined by socioeconomic factors. The EQ-5D index is calculated based on the time trade-off tariff. Distributions of study subjects by study variables are described with 95% confidence intervals. Multivariate analyses are performed to identify socioeconomic determinants of HRQoL, need of support, ADL index, and willingness to use and pay for models of care. In addition, four focus group discussions with the elderly, their household members, and community association representatives were conducted to explore perspectives on the use of services by applying content analysis. Results Life expectancy at age 60 increased by approximately one year from 1999-2002 to 2003-2006, but tended to decrease in the most vulnerable groups. There is a wide gap in life expectancy by poverty status and living arrangement. The sex gap in life expectancy is consistent across all socioeconomic groups and is wider among the more disadvantaged populations. The EQ-5D index at old age is 0.876. Younger age groups, position as household head, working, literacy, and belonging to better wealth quintiles are determinants of higher HRQoL. Ageing has a primary influence on HRQoL that is mainly due to reduction in physical (rather than mental) functions. Being a household head and working at old age are advantageous for attaining better HRQoL in physical rather than psychological terms. Economic conditions affect HRQoL through sensory rather than physical functions. Long-term living conditions are more likely to affect HRQoL than short-term economic conditions. Dependence in instrumental or intellectual activities of daily living (ADLs) is more common than in basic ADLs. People who need complete help are fewer than those who need some help in almost all ADLs. Over two-fifths of people who needed help received enough support in all ADL dimensions. Children and grand-children are confirmed to be the main caregivers. Presence of chronic illness, age groups, sex, educational level, marital status, household membership, working status, household size, living arrangement, residential area, household wealth, and poverty status are determinants of the need for care. Use of mobile teams is the most requested service; the fewest respondents intend to use a nursing centre. Households expect to use services for their elderly to a greater extent than did the elderly themselves. Willingness to use services decreases when potential fees increase. The proportion of respondents who require free services is 2 to 3 times higher than those willing to pay full cost. Households are willing to pay more for day care and nursing centres than are the elderly. The elderly are more willing to pay for mobile teams than are their households. ADL index, age group, sex, literacy, marital status, living arrangement, head of household status, living area, working status, poverty and household wealth are factors related to willingness to use services. Conclusions There is a trend of increasing life expectancy at older ages in ruralVietnam. Inequalities in life expectancy exist between socioeconomic groups. HRQoL at old age is at a high level, but varies substantially according to socioeconomic factors. An unmet need of daily care for older people remains. Family is the main source of support for care. Need for care is in more demand among disadvantaged groups. Development of a social network for community-based long-term elderly care is needed. The network should focus on instrumental and intellectual ADLs rather than basic ADLs. Home-based care is more essential than institutionalized care. Community-based elderly care will be used and partly paid for if it is provided by the government or associations. The determinants of elderly health and care needs should be addressed by appropriate social and health policies with greater targeting of the poorest and most disadvantaged groups. Building capacity for health professionals and informal caregivers, as well as support for the most vulnerable elderly groups, is essential for providing and assessing the services. / Aging and Living Conditions Program / Vietnam-Sweden Collaborative Program in Health, SIDA/Sarec
