Kochová, Agata January 2015 (has links)
The experiment was based on the feeding of feed additive, which was composed of vitamins, methionine, zinc and copper in organic form (amino acid complex n-hydrate). The experiment was 14 horses divided into two groups (test and control group). The experimental group was the basic ration, which also received a control group, added over a period of nine months, a feed additive. During the experiment, 5 samples were taken from which the detected concentration of some mineral elements (Ca, Fe, Mg, Cu, Zn) and various biochemical parameters (glucose, aspartate aminotransferase, urea, bilirubin, alkaline phosphatase). Administration of a feed additive was a statistically significant (P <0.05) increase in the zinc content of the original 5828 mg +- 1.67 10.57 +- 0.79 four milligrams. The copper content in the control sampling was 10.737 +- 2.46 and statistically significantly increased to 12.698 +- 1.74 mg. Check sampling contained 4.58 +- 0.56 mmol / l glucose, the last collection and showed no significant difference statistically insignificant (P <0.01) was 4.45 +- 0.46 mmol/l. In the control sampling was determined the average number of aspartate aminotransferase to 2.46 +- 0.48 mikromol/l, which is due to the administration of feed additives statistically insignificant (P <0.01) increased to 3.37 +- 0.71 mikromol/l.. Blood urea is statistically insignificant (P <0.01) did not change much, the initial value of 5.86 +- 1.20 mmol / l decreased to 5.75 +- 1.17 mmol / l. Bilirubin is statistically insignificant (P <0.01) without significant deviation from the initial 14.61 +- 5.45 mikromol/l slightly increased to 14.78 +- 6.41 mikromol/l.. Alkaline phosphatase statistically significant (P <0.05) increased from 1.98 +- 0.34 mikromol/l to 3.18 +- 0.66 mikromol/l.

Análisis de modos de falla en el proceso de detonación electrónica

Lepileo Soriano, Paola Consuelo January 2012 (has links)
Ingeniera Civil Electricista / El aumento de la inversión extranjera en la industria minera chilena ha generado la necesidad de mejorar los procesos de extracción y tratamiento del mineral, así como de implementar políticas de disminución en sus costos asociados. Inicialmente, dichas políticas se centraron en disminuir los costos en el proceso de tronadura, apuntando mayormente al desarrollo de métodos que permitan conseguir una roca más fragmentada, y por ende, un menor gasto de recursos en el resto del proceso de obtención de mineral. En este sentido, los dispositivos I-Kon, una línea de detonadores electrónicos programables, permiten una asignación de tiempo de detonación para obtener una tronadura mucho más precisa. Debido a la gran cantidad de fallas que se presentan en el proceso de detonación controlado con I-Kon, surge la necesidad de un estudio sobre este proceso. El presente trabajo de título tiene la finalidad de realizar un estudio FMECA (Fault Mode, Effects and Criticality Analysis) para el proceso de detonación impuesto por Orica Chile S.A y controlado por los dispositivos I-Kon en la división Orica Mining Services. Este estudio se realiza en dos de las muchas mineras a las que la empresa presta servicios: Compañía Minera Doña Inés de Collahuasi y Compañía Minera Spence. Para la realización de este estudio se analiza detalladamente el proceso de detonación, identificando los posibles modos de falla, sus causas, nivel de impacto en la operación y sus efectos. Además se lleva a cabo una serie de encuestas a los operadores de los equipos I-Kon, para así obtener información sobre la frecuencia y criticidad de estas fallas. Con estos datos realizan una serie de gráficos que relacionan las fallas provocadas por algún tipo de causa con su criticidad y frecuencia. Como resultado de este estudio se determinan las causas de las fallas más importantes del proceso de detonación, donde cuatro de las seis causas más significativas se asocian directamente a descuidos de los operadores en las distintas etapas del proceso. Para cada causa se sugieren medidas preventivas para evitar la aparición de fallas y en consecuencia, evitar los atrasos que éstas implican para la producción. Se sugiere también, como trabajo futuro, una mejora en los procedimientos de prevención para fallas causadas por problemas de interferencia, las cuales con un estudio más detallado de la correlación entre el campo electromagnético, la humedad del medio y la conductividad del mineral, podrían resultar en nuevas medidas de programación de tronaduras.

Enter Paranoia: Identity and "Makeshift Salvations" in Kon Satoshi's "Paranoia Agent"

Hanson, Jeffrey Steven January 2007 (has links)
Kon Satoshi's Paranoia Agent is a series that demonstrates how many types of identity are constructed. While some aspects of the series are based in fantasy, Paranoia Agent takes place in a Tokyo that closely resembles the Tokyo of the real world. In particular, a corporate icon named Maromi parallels the rise of icons such as Hello Kitty in Japan; the public's devotion to Maromi demonstrates how consumerism shapes one's personal identity. Consumerism can also be used to explain the existence of Lil' Slugger, a type of phantasm who initially appears to free the people of Tokyo from their problems, but is actually a "crutch" that society uses to run away from reality. The destination of this escape can be called "consumutopia," a virtual space of "perfect consumption" where reality can be ignored. Consumutopia is one example of the - real or metaphorical - "spaces" that are examined in Paranoia Agent.

Reflections on the Subtitling and Dubbing of Anime: The Translation of Gender in Perfect Blue, a Film by Kon Satoshi

Josephy, Daniel Enrique January 2017 (has links)
Perfect Blue is an anime (Japanese animation) film directed by Kon Satoshi released in 1997. The film revolves around a female idol (a pop star) named Mima who quits her career as an idol to become an actress. She gradually loses her mind, as the pressures from her acting career, her managers, fans and a stalker catch up to her. Perfect Blue touches on the blurring line between fiction and reality, the objectification of women (and idols) as mere products, and the role of women in the idol industry. It is also a stark critique of the hegemonic masculinity and the gender roles that are imposed on women in Japanese society. This thesis presents anime as an important pop culture phenomenon with a massive influence worldwide. The thesis examines the gender stereotypes propagated by this phenomenon and proposes a that Kon’s work is different compared to other anime. This work compares how gender roles are portrayed in the different versions: The Japanese original and the US English subtitles and dubbing. Methodologically, the analysis relies on close observation of the use of the Japanese first and second person pronouns and sentence-final particles in the characters’ language, since “the use of these features is known to be highly gender-dependent” (Hiramoto 2013, 55). This study comes to the conclusion that the subtitles and the dubbing provide a relatively close rendering of gender of the Japanese text, even if the linguistic resources of English do not allow for the translation of gendered Japanese pronouns and sentence-final particles. This means that the subtitles and dubbings maintain the feminist message Kon wanted to give in his film. The study concludes by stressing the importance of taking into account the use of specific pronouns and sentence-final particles when translating Japanese, as these particles are gender-loaded. It also emphasises the importance of being critical of anime’s hegemonic masculinity, and argues that Kon goes against hegemony by portraying a strong and independent female character.

Structure and restoration of natural secondary forests in the Central Highlands, Vietnam

Bui, Manh Hung 15 December 2016 (has links) (PDF)
Introduction and objectives In Vietnam, the forest resources have been declining and degrading severely in recent years. The degradation has decreased the natural forest area, changed the forest structure seriously and reduced timber volume and biodiversity. From 1999 to 2005, the rich forest area has decreased 10.2%, whereas the poor secondary forest has increased dramatically by 20.7%. Forest structure plays an important role in forestry research. Understanding forest structure will unlock an understanding of the history, function and future of a forest ecosystem (Spies, 1998). The forest structure is an excellent basis for restoration measures. Therefore, this research is necessary to contribute to improving forest area and quality, reducing difficulties in forest management. The study also enhances the grasp of forest structure, structure changes after harvesting and fills serious gaps in knowledge. In addition, the research results will contribute to improving and rescuing the poor secondary forest and restoring it, approaching the old-growth forest in Vietnam. Material and methods The study was conducted in Kon Ka Kinh national park. The park is located in the Northeastern region of Gia Lai province, 50 km from Pleiku city center to the Northeast. The park is distributed over seven different communes in three districts: K’Bang, Mang Yang and Đăk Đoa. Data were collected from 10 plots of secondary forests (Type IIb) and 10 plots of primeval forests (Type IV). Stratified random sampling was applied to select plot locations. 1 ha plots were used to investigate gaps. 2000 m2 plots were used to measure overstorey trees such as diameter at breast height, total height, crown width and species names. 500 m2 subplots were used to record tree positions. For regeneration, 25 systematic 4 m2 subplots were established inside 1 ha plots. After data were collected in the field, data analyses were conducted by using R and Excel. Firstly, some stand information, such as density, volume and so on, was calculated, and then descriptive statistics were computed for diameter and height variables. Linear mixed effect models were applied to analyze the difference of diameter and height and to check the effect of random factor between the two forest types. Diameter and height frequency distributions were also generated and compared by using permutational analysis of variance (PERMANOVA). Non-linear regression models were analyzed for diameter and height variables. Similar analyses were implemented for gaps. Regarding spatial point patterns of overstorey trees, replicated point pattern analysis techniques were applied in this research. For biodiversity, some calculations were run such as richness and biodiversity indices, comparison of biodiversity indices by using linear mixed models and biodiversity differences between two forest types tested again by permutational analysis of variance. In terms of regeneration, some analyses were implemented such as: height frequency distribution generation, frequency difference testing, biodiversity indices for the regeneration and spatial distribution checking by using a nonrandomness index. Results and discussion After analyzing the data, some essential findings were obtained as follows: Hypothesis H1 “The overstorey structure of secondary forests is more homogeneous and uniform than old-growth forests” is accepted. In other words, the secondary forest density is about 1.8 times higher than the jungle. However, the volume is only 0.56 times as large. The average diameter and height of the secondary forest is smaller by 5.71 cm and 3.73 m than the old-growth forest, respectively. Linear mixed effect model results indicate that this difference is statistically different and the effect of the random factor (Section) is not important. Type IIb has many small trees and the diameter frequency distribution is quite homogeneous. The old-growth forest has more big trees. For both forest stages, the height frequency distribution is positively skewed. PERMANOVA results illustrate that the frequency distribution is statistically different between the two forest types. Regression functions are also more variant and diverse in the old-growth forest, because all standard deviations of the parameters are greater there. Gap analysis results indicate that the number of gaps in the young forest is slightly higher, while the average gap size is much smaller. The gap frequency distribution is statistically different between the two types. In terms of the spatial point pattern of overlayer trees, the G-test and the pair correlation function results show that trees distribute randomly in the secondary forest. In contrast, the spatial point patterns of trees are more regular and diverse in the old-growth forest. The spatial point pattern difference is not significant, and this is proved by a permutational t-test for pair correlation function (pcf). Envelope function results indicate that the variation of pcf in young forests is much lower than in the primary forests. Hypothesis H2 “The overstorey species biodiversity of the secondary forest is less than in the old-growth forest” is rejected. Results show that the number of species of the secondary forest is much greater than in the old-growth forest, especially richness. The richness of the secondary forest is 1.16 times higher. The Simpson and Shannon indices are slightly smaller in the secondary forest. The average Simpson index for both forest stages is 0.898 and 0.920, respectively. However, the difference is not significant. Species accumulation curves become relatively flatter on the right, meaning a reasonable number of plots have been observed. Estimated number of species from accumulation curves in two forest types are 105 and 95/ha. PERMANOVA results show that number of species and proportion of individuals in each species are significantly different between forest types. Hypothesis H3 “The number regenerating species of the secondary forest is less and they distribute more regularly, compared to the old-growth forest” is rejected. There are both similarities and differences between the two types. The regeneration density of the stage IIb is 22,930 seedlings/ha, greater than the old forest by 9,030 seedlings. The height frequency distribution shows a decreasing trend. Similar to overstorey, the richness of the secondary forest is 141 species, higher than the old-growth forest by 9 species. Biodiversity indices are not statistically different between two types. PERMANOVA results indicate that the number of species and the proportion of individuals for each species are also not significantly different from observed forest types. Nonrandomness index results show that the regeneration distributes regularly. Up to 95% of the plots reflect this distribution trend. Hypothesis H4 “Restoration measures (with and without human intervention) could be implemented in the regenerating forest” is accepted. The investigated results show that the secondary forest still has mother trees, and it has enough seedlings to restore. Therefore, restoration solutions with and without human intervention can be implemented. Firstly, forest protection should be applied. This measure is relevant to national park regulations in Vietnam. Rangers and other related organizations will be responsible for carrying out protection activities. These activities will protect forest resources from illegal logging, grazing and tourist activities. Environmental education and awareness-raising activities for indigenous people is also important. Another measure is additional and enrichment planting. It should focus on exclusive species of the overstorey in Type IIb or exclusive species of the primary forest. Selection of these species will lead to species biodiversity increase in the future. This also meets the purpose of the maximum biodiversity solution. Conclusion Forest resources play a very important role in human life as well as maintaining the sustainability of ecosystems. However, at present, they are under serious threat, particularly in Vietnam. Central Highland, Vietnam, where forest resources are still relatively good, is also threatened by illegal logging, lack of knowledge of people and so on. Therefore, it needs the hands of the people, especially foresters and researchers. Through research, scientists can provide the knowledge and understanding of the forest, including the structure and forest restoration. This study has obtained important findings. The secondary forest is more homogeneous and uniform, while the old-growth forest is very diverse. Biodiversity of the overstorey in the secondary forest is more than the primary. The number of regenerating species in the secondary forest is higher, but other indices are not statistically different between two types. The regeneration distribute regularly on the ground. The secondary forest still has mother trees and sufficient regeneration, so some restoration measures can be applied here. Findings of the study contribute to improve people’s understanding of the structure and the structural changes after harvesting in Kon Ka Kinh national park, Gia Lai. That is a key to have better understandings of the history and values of the forests. These findings and the proposed restoration measures address rescuing degraded forests in Central Highland in particular and Vietnam in general. And further, this is a promising basis for the management and sustainable use of forest resources in the future.
