Abstract:

Vertical continuous ore haulage with elevators in mining for deep haulage is virtually non-existent. In this, research investigations concentrated on a cable disc elevator. The problem of using a cable disc elevator is the friction between the elevator fixed tube and the moving ore on the disc. This research establishes the friction forces existing as the elevator cable and discs are elevated up a stationary tube. Then the focus is to find a way to eliminate that friction. The method involved developing three test rigs: Test Rig 1 measures static friction with the ore placed on a disc in a tub

Abstract:

In this thesis, a practical vector controlled elevator drive is presented. Indirect vector control of induction machine is investigated in theory and then implemented. Control technique is compared with scalar control and induction machine is compared with dc motor. The operation of the system depends on induction machine parameters, so how to accurately and automatically obtaining of the parameters is also presented. Finally, the elevator system is introduced, the application of this control system to the elevator system is described and a basic elevator control system is simulated.

In anticipation of potential changes in forest composition, vegetation surveys were first conducted in 1966 on nine one-acre plots near the summit of Mt. Mitchell. These plots were re-surveyed in 1978, 1985 and 2002. The purpose of this study was to re-census those plots and use those data to analy

Material and methods. This systematic review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines (1) with the focused question b

Abstract:

Atualmente, a demanda por próteses implantossuportadas está constantemente a aumentar, o que requer um volume ósseo suficiente podendo levar á necessidade de contributos ósseos. Estas contribuições ósseas podem ser feitas usando osso autógeno ou biomateriais. A existência de deficiências ósseas na região posterior da maxila pode exigir um enchimento parcial do seio maxilar, quando o espaço inter-arcadas é normal, mas a altura do osso-sinusal é insuficiente para a colocação de um implante. Esse preenchimento pode ser feito por meio de duas técnicas, a elevação do seio pela janela de acess

Abstract:

Atmospheric concentrations of CO2 have risen considerably since the industrial revolution due to human activity. Without extreme intervention, climate forecasts indicate that atmospheric CO2 concentrations will continue to rise. Plant growth and productivity in response to elevated CO2 has been studied extensively, however, few studies explore how reproduction will be affected under future CO2 concentration; particularly for long-lived woody plant species. This study is undertaken within the EucFACE facility in Western Sydney (Australia), with naturally growing populations, on nutrient limited

Abstract:

University of Technology Sydney. Faculty of Health.<br>[Background] Health-related quality of life (HRQOL) is an important measure of patient outcome following primary percutaneous coronary intervention (PPCI) for an ST-Elevation myocardial infarction (STEMI). The assessment of HRQOL quantifies patient perceptions of the impact of an acute, unanticipated cardiac event on their survival and normal function. Despite international recognition and recommendations supporting HRQOL as a vital measure of cardiovascular health status, HRQOL remains under-reported and not routinely implemented in PPCI

Abstract:

Introdução: A região edentulosa posterior maxilar apresenta muitas condições únicas e desafiadoras na odontologia do implante, como baixa qualidade óssea e volume limitado devido à presença do seio maxilar. Todos estes parâmetros influenciam diretamente a estabilidade primária de um implante dentário, fundamental para o sucesso da cirurgia e para alcançar a osseointegração do implante. Já conhecemos o princípio do enxerto do seio lateral, a fim de aumentar a altura do osso alveolar e, assim, a ancoragem do implante. Mas continua a ser uma cirurgia bastante invasiva com os riscos e complicações

Abstract:

Mg-Druckgusslegierungen sind aufgrund ihrer geringen Dichte potenzielle Leichtbauwerkstoffe. Ihre Festigkeitseigenschaften werden durch erhöhte Temperatur und die druckgussprozessbedingte Porosität maßgeblich beeinflusst. Zur Auslegung zyklisch belasteter Mg-Druckgussbauteile für eine begrenzte Betriebsdauer kann das Örtliche Konzept verwendet werden. Im Örtlichen Konzept nimmt das zyklische Werkstoffverhalten eine zentrale Rolle ein. Es umfasst das zyklische Verformungsverhalten und das zyklische Ermüdungsverhalten. Zur Beschreibung des zyklischen Werkstoffverhaltens werden die zyklische Span

Objetivo: analisar e comparar os resultados de dois substitutos ósseos xenógenos, Bio-Oss® e Cerabone®, na colocação de implantes na maxila, recorrendo à elevação do seio maxilar e elevação do soalho do nariz. Métodos: realizou-se uma pesquisa bibliográfica, com recurso à base de dados PubMed e, seguindo as metodologias PICO e PRISMA (critérios de inclusão e exclusão). Inicialmente, a pesquisa foi limitada a RCTs, não existindo artigos disponíveis, o âmbito foi alargado a revisões e a estudos clínicos. Resultados: foram obtidos e analisados onze estudos comparando a regeneração óssea de duas m

Abstract:

The aim of this study was to systematically review sinus graft infection management in order to define which protocols should be implemented. The terms searched in each database were “sinus graft infection management”, “maxillary sinus lift infection”, “maxillary sinus graft infection”, “maxillary sinus elevation infection”, “maxillary sinus augmentation infection”. The outcome evaluated both maxillary sinus health and implantological result. The initial search yielded 1190 results. 18 articles were included counting 3319 patients and 217 sinus graft infections. In every study, all patients
