Exposure Process

Most production electron beam lithography systems can pattern minimum features a few tenths of a micron across. Linewidth in these systems is usually limited by the quality of the exposing beam and by electron scattering in the resist and substrate. By using a smaller spot along with exposure techniques that minimize scattering and its effects, laboratory e-beam lithography systems can now make features hundredths of a micron wide on standard substrate material. This talk will outline sane of these high- resolution e-beam lithography techniques.We first consider parameters of the exposure process that limit resolution in organic resists. For concreteness suppose that we have a “positive” resist in which exposing electrons break bonds in the resist molecules thus increasing the exposed resist's solubility in a developer. Ihe attainable resolution is obviously limited by the overall width of the exposing beam, but the spatial distribution of the beam intensity, the beam “profile” , also contributes to the resolution. Depending on the local electron dose, more or less resist bonds are broken resulting in slower or faster dissolution in the developer.

The study aims to analyze about the low graduation and certification exam training participants of the procurement of goods / services of the government and its contributing factors, and formulate a strategy of education and training and skills certification exams procurement of goods / services of the government. Collecting data using the method of study documentation, interviews, and questionnaires. Is the official source of information on the structural and functional Regional Employment Board, as well as the participants of the training and skills certification exams procurement of goods / services of the government in Magelang regency government environment. Analysis using 4 quadrant SWOT analysis, to determine the issue or strategic factors in improving the quality of education and training and skills certification exams procurement of government goods / services within the Government of Magelang regency. The results show organizer position is in quadrant I, which is supporting the growth strategy, with 3 alternative formulation strategies that improve the quality of education and training and skills certification exams procurement of government goods / services, and conducts certification examination of the procurement of government goods / services with computer assisted test system (CAT). Based on the research recommendations formulated advice to the organizing committee, namely: of prospective participants of the training and skills certification exams procurement of goods / services the government should consider the motivation of civil servants, is examinees who have attended training in the same period of the year, the need for simulation procurement of goods / services significantly, an additional allocation of training time, giving sanction to civil servants who have not passed the exam, the provision of adequate classroom space with the number of participants of each class are proportional, as well as explore the evaluation of education and training and skills certification exams procurement of goods / services for Government of participants.

We formulated the principles of designing bioluminescent enzyme tests for assessing the quality of complex media which consist in providing the maximum sensitivity to potentially toxic chemicals at a minimal impact of uncontaminated complex media. The developed principles served as a basis for designing a new bioluminescent method for an integrated rapid assessment of chemical safety of fruits and vegetables which is based on using the luminescent bacterium enzymes (NAD(P)H:FMN oxidoreductase and luciferase) as a test system.

Centralization And Decentralization

Trailing back from quasi decentralisation to centralisation. Municipal reform in Hungary It is very difficult to group countries and state structures according to the extent of their decentralization or the model they follow in the spatial distribution of power. The bounds of responsibility of local government and the state, the distribution of the roles and tasks between the two stakeholders and the question of centralization and decentralization are issues regularly debated in recent years and today. This topic is not merely a public administration, financial or state organization issue since these decisions have a direct impact on citizens’ lives through public services. In my study I wish to introduce this process via Hungary’s example. I also examine how and what those concerned by the financial and political changes, i.e. the population perceived of this most important structural transformation of the period since the transition in 1989. Can it be verified from the consumers’ point of view that the transformation of the local municipal system improves the quality of service provision?

Aims: Caseins are among the main milk proteins that determine many of its properties. Bovine kappa-casein (CSN3) is associated with the qualitative composition of milk, as well as with the quality of cheese obtained from this milk. The rs43703016 single-nucleotide substitution (g.88532332A>C; Asp148Ala) in exon 4 of the bovine CSN3 gene plays an important role in the production of quality hard cheeses. Various methods for the DNA testing of this substitution have been developed in the last three decades. Emergent DNA technologies provide an opportunity to modernize methods of genotyping single-nucleotide polymorphisms. Results: We have developed and verified a method to differentiate A/C alleles of the rs43703016 substitution in the bovine CSN3 gene by real-time PCR using allele-specific fluorescent probes. Conclusion: Our new method allows fast genotyping of animals, and may be used for selection of cows carrying the CC genotype, which determines good cheese-making properties of milk.

<p>La calidad fisiológica de la semilla podría afectar el rendimiento de granos de arroz. Las diferencias en la calidad fisiológica de las semillas pueden causar la reducción y desuniformidad de la emergencia en el campo, acarreando una diferencia en el crecimiento inicial de las plantas, y consecuentemente afectando el cultivo y su rendimiento. Se realizo un experimento con el objetivo de evaluar la distribución espacial y la variabilidad en la población entre las plantas de arroz, en función de la calidad fisiológica de las semillas. Fueron utilizados nueve lotes de semillas de la cultivar BR-IRGA 410, siendo tres de alta, tres de media y tres de baja calidad fisiológica. Cada bloque consistió de nueve líneas de 5,5 metros de longitud, separadas por 0,12 metros. Se evaluó el número de fallas consecutivas y la variabilidad entre las plantas a través del coeficiente de variación de la altura de plantas y de la materia seca. El uso de las semillas con baja calidad fisiológica proporcionó mayor desuniformidad en la distribución espacial de la planta en el campo, y una mayor variabilidad entre las plantas que componen la población, lo que puede proporcionar un aumento en la competencia intra-especifica.</p><p align="center"><strong><em>Seeds physiological quality and variability among plants in populations of rice</em></strong><strong><em> </em></strong></p><p><strong>Abstract: </strong>Several authors try to relate the physiological quality of seeds with grain yield of rice. Differences in the physiological quality of seeds can cause reduction and uniformity of emergence in the field, leading to differential on early seedling growth, and consequently affecting the culture and your yield. An experiment was conducted to evaluate the spatial distribution and variability in populations of rice plants, depending on the physiological quality of seeds. Were used nine seed lots of cultivar BR-IRGA 410, three lots of high, three lots of medium and three lots of low physiological quality. Each block was composed of nine lines of 5.5 meters in length, spaced 0.12 meters. We evaluated the number of consecutive failures in emergence, and plant variability through the coefficient of variation of plant height and dry matter. The use of seed with low physiological quality provides increased uniformity in the spatial distribution of plants in the field, and greater variability from plants comprising the population, which can provide an increase in intra-specific competition.</p><p> </p>
