The tuning pins of the old Gaelic harps are beautifully crafted art objects in their own right, all handmade to the highest standards and constituting perhaps the most time consuming and expensive part of an instrument. I am dividing the old Gaelic harp tuning pins into three different types, which we can describe as medieval, 17th century and 18th century. Medieval style tuning pins The brass tuning pins on the Queen Mary and Trinity College harp are likely medieval in date.
They are simple in outline and profile, but have incised grooves running around the drives and incised cross-hatching in the ends. The Queen Mary pin drives are rectangular cross-section, while the Trinity pins are square.

High-precision radiocarbon dating of a wooden lintel beam from the Classic Maya site of Tikal in Guatemala could help to resolve the longstanding problem of aligning the calendars of ancient Maya and modern Europe. The research, published in Scientific Reports this week, allows the precise dating of events at the end of the seventh century AD and adds support to the hypothesis that climate change had an important role in the development and demise of the Maya civilization. The reasons for the rise and fall of the Maya civilization remain uncertain.
Historical events carved on stone monuments in the region represent a valuable source of data, but their use requires a precise correlation of the Maya and European calendars. Douglas Kennett and colleagues used accelerator mass spectrometry radiocarbon dating to analyse the markings on a wooden lintel from Tikal that bears Maya calendar dates. The findings show the dates were carved on the lintel between AD and , supporting the most widely accepted correlation constant, the Goodman-Martinez-Thompson correlation, which was first proposed over years ago.
These events and those recorded in other Mayan cities can now be studied more closely in the context of other environmental, climatic and archaeological data from the regions, the authors conclude.

To establish pitches, 12 bamboo pipes, closed at one end, were cut into graduated lengths. These pipes should not be confused with the panpipe , or paixiao. According to legend , Huangdi, the Yellow Emperor , sent the minister Ling Lun to find bamboo tubes to use for tuning pipes. To create the succeeding pitches he was said to have listened to the calls of the fenghuang birds and then cut the pipes accordingly. In fact, the generation of the 12 pitches was straightforward.
Given a first pipe length, the second was cut according to a ratio of , which produced a pitch a fifth higher e.

The tutorial involves co-estimation of a gene phylogeny and associated divergence times in the presence of calibration information from fossil evidence. This tutorial will guide you through the analysis of an alignment of sequences sampled from twelve primate species see Figure 1. The goal is to estimate the phylogeny, the rate of evolution on each lineage and the ages of the uncalibrated ancestral divergences.
This is a user-friendly program for setting the evolutionary model and options for the MCMC analysis. The final step is to explore the output of BEAST in order to diagnose problems and to summarize the results.

However, in an in vitro fertilisation IVF setting, frozen embryo transfer ET has had a low success rate. We propose that in patients with previously failed ET attempts, the uterine epithelium can be directly visualised by biopsy and Scanning Electron Microscopy SEM and that with an individualised fine tuning of the hormone supplementation regime, based on the SEM examination of sequential uterine biopsies, it is possible to provide a uterine environment conducive to successful ET. METHODS: A 47 year old women was chosen for endometrial biopsy, histopathological dating and endometrial observation utilising SEM to determine the integrity of her secretory uterine epithelium because of her age and several previously failed attempts at frozen ET.
Exogenous E2 and P4 supplementation was administered in modified doses according to the SEM result, in consecutive cycles until the epithelial response appeared satisfactory for potential implantation. The uterine morphology changed from a hypotrophic to a mature, receptive epithelium such that ET resulted in the birth of healthy twin boys.
