The Complexity of Splay Trees and Skip ListsSayed, Hassan Adelyar. January 2008 (has links)
Magister Scientiae - MSc / Our main results are that splay trees are faster for sorted insertion, where AVL trees are faster for random insertion. For searching, skip lists are faster than single class top-down splay trees, but two-class and multi-class top-down splay trees can behave better than skip lists. / South Africa

Avaliação da limpeza das paredes em canais radiculares instrumentados pelas técnicas rotatória e self-adjusting file (SAF) associadas ao uso de diferentes quelantes / Evaluation of the cleanness of root canals walls instrumented with rotary and the self-adjusting file (SAF) techniques associated with different chelatorsFerraz, José Antonio Brufato 27 April 2012 (has links)
O presente trabalho avaliou, por microscopia eletrônica de varredura (MEV), a limpeza das paredes dos canais radiculares instrumentados pelas técnicas rotatória e Self-adjusting file (SAF®) com uso do NaOCl a 1% como solução irrigadora e o uso do EDTA a 15% e da Quitosana 0,20% como soluções quelantes, e quantificou os íons cálcio removidos pelas diferentes soluções irrigadoras por meio de espectrometria de absorção atômica. Trinta dentes caninos inferiores humanos foram divididos em dois grupos (n=15), de acordo com a técnica de instrumentação utilizada: A - instrumentos FlexMaster® usados na técnica Free Tip Preparation, assegurado alargamento mínimo de 200, até o instrumento # 60.02, irrigados com 1 mL de NaOCl 1% em cada troca de instrumento e B - sistema SAF®, com prévio alargamento manual até o instrumento K #20, aplicação da SAF® por 4 minutos, com fluxo de irrigação pelo sistema VATEA de 5mL/min. Os dentes foram divididos em três subgrupos conforme a irrigação final: G1-NaOCl 1%, G2- EDTA 15% e G3 Quitosana 0,20%. Utilizou-se 5mL de cada solução à 1mL/min. A solução extravasada pelo forame foi coletada e submetida à análise espectrométrica. O EDTA 15% apresentou maior capacidade de remoção de íons cálcio do que a Quitosana a 0,20% (p<0,05) e o NaOCl 1% não removeu íons. Os espécimes foram analisados em MEV. As fotomicrografias obtidas foram avaliadas qualitativamente em relação à remoção da camada de smear observada. Não houve diferença entre as instrumentações rotatória e SAF® nos terços dos canais avaliados. Analisadas as interações entre as técnicas utilizadas e aos terços do canal, o EDTA 15% apresentou melhores resultados que a Quitosana 0,20% (p<0,05), sendo ambas as soluções melhores que o NaOCl 1%. Conclui-se que as soluções quelantes testadas foram capazes de remover íons cálcio das paredes dos canais radiculares - com superioridade do EDTA 15% sobre a Quitosana 0,20%, e o NaOCl a 1% não apresentou essa capacidade - e removeram a camada de smear das paredes dos canais radiculares com superioridade do EDTA 15%, sem interferência das técnicas de instrumentação avaliadas rotatória e SAF®. / The present study evaluated, by scanning electron microscopy (SEM), the cleanness of the root canal walls instrumented by rotary and the self-adjusting file (SAF®) techniques using 1% NaOCl as an irrigating solution and 15% EDTA, 0.20% Chitosan as chelator solutions, and quantified the calcium ions removed by the different irrigants with atomic absorption spectrometry. Thirty human mandibular canine teeth were divided into 2 groups (n=15) according to the instrumentation technique used: A- FlexMaster® instruments used with the Free tip Preparation, assuring a minimal enlargement of 200m, up to a #60 .02 instrument, irrigated with 1mL of 1% NaOCl between each instrument; and B- SAF® system, with previous enlargement to a type K #20 manual instrument, application of SAF during 4 minutes, with VATEA irrigation system at a flow of 5mL/min. The teeth were divided into three subgroups according to the final irrigation protocol: G1- 1% NaOCl, G2- 15% EDTA and G3- 0.20 % Chitosan. Five mL of solution were used at 1mL/min. The solution extruded thru the foramen was collected and submitted to spectrometric analysis. 15% EDTA showed higher calcium ion removal capacity then 0.20% Chitosan (p<0.05) and the 1% NaOCl did not remove ions. The specimens were evaluated by means of SEM. The photomicrographs obtained were qualitatively evaluated in terms of smear layer removal. There was no significant difference between the rotary and SAF® instrumentation systems in the evaluated canal thirds. The interaction techniques used and canals thirds showed that the 15% EDTA revealed better results than the 0.02% Chitosan (p<0.05), and both were better than 1% NaOCl. It can be concluded that the tested chelating solutions removed calcium ions from the root canals walls with better results for 15% EDTA than 0.20% Chitosan; 1% NaOCl did not present this capacity - and removed the smear layer form the root canal walls with better results for 15% EDTA, with no difference between the evaluated techniques rotary and SAF®.

Previous issue date: 2016-04-19 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Abstract: Objective: To evaluate the effectiveness of complementary protocols of
sanitization in the decontamination of infected root canals. Methods: Fifty uniradicular
maxilary anterior human teeth were selected. The crowns were removed and the lengths
standardized at 16 mm. The specimens were inoculated with Enterococcus faecalis and
incubated at 37 °C for sixty days. Thirty teeth were performed with BioRace instruments
until diameter corresponding to #60.02, and then complemented with Self-Adjusting File
(SAF); XP-endo Finisher (XPF) and passive ultrasonic irrigation (PUI). Ten samples were
used as positive control and 10 were not contaminated. Initial and final samples were
collected and incubated at 37 °C for a period of 48 hours. The bacterial growth was
analyzed in culture, determining the presence or absence of bacteria. The optical density
of the culture medium was interpreted by UV spectrophotometry. The specimens were
sectioned and prepared for evaluation in SEM. The images of the root surfaces were
analyzed and classified by scores according to the presence of debris. The Kruskal-Wallis
test was used for statistical analysis. The level of significance was 5%. Results: The
mean optical density (μm) of the sanification protocols showed bacterial reduction in all
groups. The experimental groups did not present statistically significant differences (p =
0.196). The analysis of SEM images revealed no significant difference (p = 0.414)
between the scores of the groups. Conclusion: Complementary sanitization protocols
reduced bacterial contamination. / Resumo: Objetivo: Avaliar a efetividade de protocolos complementares de sanificação na
descontaminação de canais radiculares infectados. Materiais e métodos: Cinquenta dentes

removidas e os comprimentos padronizados em 16 mm. Os espécimes foram inoculados com
Enterococcus faecalis e incubados a 37°C por sessenta dias. Trinta dentes foram preparados
com instrumentos BioRace até alcançar o diâmetro correspondente ao #60.02, e a seguir
complementados com Self-Adjusting File (SAF); XP-endo Finisher (XPF) e irrigação
ultrassônica passiva (PUI). Dez amostras foram usadas como controle positivo e 10 não
foram contaminadas. Amostras inicial e final foram coletadas e incubadas a 37°C por um
período de 48 horas. O crescimento bacteriano foi analisado em cultura, determinando a
presença ou ausência de bactérias. A densidade óptica do meio de cultura foi interpretada por
espectrofotometria UV. Os espécimes foram seccionados e preparados para avaliação em
MEV. A análise das imagens das superfícies radiculares foram analisadas e classificadas em
scores de acordo com a presença de debris. O teste de Kruskal-Wallis foi utilizado para as
análises estatísticas. O nível de significância foi 5%. Resultados: A média da densidade óptica
(μm) dos protocolos de sanificação revelou redução bacteriana em todos os grupos. Os grupos
experimentais não apresentaram diferenças estatisticamente significante (p=0,196). A análise
das imagens de MEV revelou ausência de diferença significante (p=0,414) entre os scores dos

The effect of the activator adjusting instrument in the treatment of chronic sacroiliac joint syndromeCoetzee, Natasha 20 May 2014 (has links)
Objective : Low back pain (LBP), and in particular sacroiliac joint syndrome, is a significant health concern for both patient and their chiropractor with regards to quality of life and work related musculoskeletal disorders. Therefore, chiropractors often utilise mechanical aids to reduce the impact on the chiropractor’s health. It is, however, important to establish whether these mechanical aids are indeed clinically effective, therefore, this study evaluated the Activator Adjusting Instrument (AAI) against an AAI placebo to determine whether this adjusting instrument is an effective aid for both the chiropractor and the patient.
Method : This randomised, placebo controlled clinical trial consisted of 40 patients (20 per group), screened by stringent inclusion criteria assessed through a telephonic and clinical assessment screen. Post receipt of informed consent from the patients, measurements (NRS, Revised Oswestry Disability Questionnaire, algometer) were taken at baseline, prior to consultation three and at the follow consultation. This procedure occurred with four interventions over a two week period.
Results:
The AAI group showed clinical significance for all clinical measures as compared to the AAI placebo group which attained clinical significance only for the Revised Oswestry Disability Questionnaire. By comparison there was only a statistically significant difference between the groups in terms of the algometer readings (p= 0.037).
Conclusion : Therefore, it is evident that the AAI seems to have clinical benefit beyond a placebo. However this is not reflected in the statistical analysis. It is, therefore, suggested that this study be repeated with a larger sample size in order to verify the effect on the statistical analysis outcomes.

Särskilt begåvade elever inom matematik : En kvalitativ studie om hur lärare beskriver sina kunskaper om särskilt begåvade elever och sin matematikundervisning med dessa elever i årskurs 1-3 / Gifted students in mathematical education : A qualitative study of how teachers describe their knowledge of gifted students and their mathematics education with these students in grades 1-3Johansson, Johanna January 2016 (has links)
The aim of this study was to research how teachers describe their knowledge of gifted students and their mathematics education with these students in grades 1-3. Through qualitative interviews eight teachers has been asked how they identify gifted students, how they adjust the education and what support they would need to befriend gifted students in mathematics education. The results indicate that the teachers are aware of the presence of gifted student in mathematics. The methods to identify and adjust teaching varied between the respondents and certain approaches was more favorable than others according to previous research. Common to all the respondents, however, was the desire for additional resource and commitment from the organization to help benefit gifted talents within mathematics. The conclusion is that today ́s teachers needs more knowledge about giftedness, as well as support in order to further promote learning for gifted students within the teaching of mathematics. / Studiens syfte var att undersöka hur lärare beskriver sina kunskaper om särskilt begåvade elever och sin matematikundervisning med dessa elever i årskurs 1-3. Genom kvalitativa intervjuer har åtta verksamma lärare intervjuats om hur de identifierar särskilt begåvade elever, hur de anpassar undervisningen samt vilket stöd lärarna anser sig behöva för att undervisa särskilt begåvade elever i matematik. Resultatet visar att pedagogerna är medvetna om förekomsten av särskilt begåvade elever inom matematiken. Metoderna för att identifiera och därefter anpassa undervisningen varierade mellan respondenterna samt vissa tillvägagångssätt var mer gynnsamma än andra enligt tidigare forskning. Gemensamt för alla respondenter var dock önskan om ytterligare resurser och satsning från organisationen för att kunna hjälpa att gynna särskilt begåvade elever inom matematikundervisningen. Utifrån detta kan man dra slutsatser om att dagens lärare behöver mer kunskap kring särskild begåvning, samt stöttning för att vidare kunna främja lärandet för särskilt begåvade elever inom matematikundervisningen.
