Organology of the Queen Mary and Lamont harps
Get PDFThe metal strung harp indigenous to Ireland and Scotland from the Medieval period
to the end of the 18th century was widely admired throughout its time period, and is
now an important part of the cultural and musical heritage of both of these countries.
This type of harp, known as the 'Irish harp', cláirseach, or clàrsach, currently has 18
known surviving instruments, including two sets of fragments. All of these harps are
now too fragile to be played, therefore musicians and audiences wishing to explore
the performance practice and repertory associated with them must rely on faithful
replicas. The extensive knowledge and understanding of the construction of the
surviving harps that is crucial to building these replica instruments is currently very
limited, however.
Although harps of this type enjoyed a long period of use dating back to the Medieval
period, most surviving instruments post-date the beginning of the 17th century. Two
harps belonging to the National Museum of Scotland, the 'Queen Mary' and 'Lamont',
generally dated to circa the 15th century, are understood to be two of the oldest
extant examples, making a study of their construction of particular interest. This
dissertation presents the results of a comprehensive study of the construction of these
two harps. A methodology was developed to address the issue of their uniqueness
and fragility by combining the techniques used for non- and minimally destructive
analysis of archeological artefacts with non-invasive medical diagnostic imaging.
This study has utilized CT-scanning to provide three-dimensional radiography of
each harp; XRF and SEM-EDX analysis to identify woods, metals, and pigments;
photography and microscopy to record the decorative work, visible damage, repairs,
and modifications; and a visual examination to assess the current state of each harp
and to identify areas of interest for further analysis. The CT scanning was conducted
at the Clinical Research Imaging Centre of Queen's Medical Research Institute, and
the remainder of the analysis was conducted at the National Museums Scotland
Collections Centre. Staff at both centres kindly facilitated the acquisition of the data
for this study.
Part I of this dissertation discusses the stringing of the instruments, presenting
materials analysis of wire fragments, analysis of the effect of damage to the frames
on the length and number of strings, and proposed reconstructions of the 'as-built'
string lengths. Possible solutions for the pitch and gamut of each harp are also
discussed. The construction of the harps is discussed where it is relevant to
understanding the stringing. Part II presents a general discussion of the construction
of each harp, including materials, decorative work, modifications, and signs of wear.
This section also discusses evidence that may help establish dates of construction and
timelines of modifications. Diagrams showing the dimensions of each harp are also
presented. The implications of the results of this study for current understanding of
these harps are discussed in detail and the methodology employed is discussed in
terms of its applicability to future research of other surviving instruments
Treatment effects of van Beek activator comparing two wear-time prescriptions assessed by microsensors: a randomized clinical trial
No full textSyfte: Syftet med den här studien var att undersöka följsamheten och reduktionen av det horisontella överbettet vid behandling med van Beek-aktivator genom att jämföra en rekommenderad användningstid av tolv och åtta timmar per dag. Material och metod: Tretton patienter (4 pojkar och 9 flickor) ingick i undersökningsmaterialet med en medelålder på 10,0 år (SD = 0,9). Alla patienter var diagnostiserade med en Angle Klass II-bettavvikelse och behandlades med van Beek-aktivator. Patienterna var randomiserade i två grupper med två olika användningstider (8 timmar och 12 timmar). Följsamheten mättes med hjälp av en mikrosensor (TheraMon®) inbyggd i aktivatorn och det horisontella och vertikala överbettet registrerades efter första, tredje och sjätte månaden. Efter att datan var insamlad gjordes statistisk analys för att påvisa ifall statistisk skillnad fanns mellan grupperna.
Resultat: Medelreduceringen i horisontellt överbett i 8-timmarsgruppen var efter sex månader 3,4 mm jämfört med hos 12-timmarsgruppen som var 3,5 mm. Medelanvändningstiden var i 12-timmarsgruppen och 8-timmarsgruppen 8.2 timmar (SD=1,7) och 7,9 timmar (SD=2,6) per dag respektive. Den genomsnittliga användningstiden för samtliga patienter var 8,1 timmar.
Slutsats: Rekommendation av åtta timmar var enklare att uppnå jämfört med tolv timmar. Van Beek-aktivatorn var effektiv för korrigering av Angle Klass II-bettavvikelser, ingen klinisk signifikant skillnad i behandlingseffekt observerades mellan de två grupperna.Aim: The aim of this study was to evaluate the compliance and overjet changes among patients treated with the van Beek activator comparing a twelve- and eight-hours daily wear-time prescription. Material and methods: The study sample consisted of thirteen patients (4 boys and 9 girls) with a mean age of 10.0 years (SD = 0.9). All patients had a Class II malocclusion and were treated with the van Beek activator. Patients were randomly assigned to two groups with a wear-time of twelve and eight hours respectively. Compliance was measured with the aid of a microsensor (TheraMon®) built into the activator and the overjet and overbite were recorded after the first, third and sixth month. Results: The mean decrease in overjet among the 8 hours group after six months was 3.4 mm compared to the 3.5 mm overjet reduction recorded in the 12 hours group. The mean wear-time in the 12 hours group and 8 hours group were 8.2 hours (SD = 1.7) and 7.9 hours (SD = 2.6) per day respectively. The overall mean daily wear-time of all patients in both groups was 8.1 hours. Conclusions: The eight-hours prescription was easier to achieve compared to the twelve-hours. The van Beek activator was effective in Class II correction, no clinically significant difference in treatment effect was observed between the two wear-time prescriptions
