Starting at OCMR
April 1st, 2008 by chris
Today, I started a new research project developing the methodology for 31P magnetic resonance imaging (MRI) at the Oxford Centre for Clinical Magnetic Resonance Research (OCMR).
I will be using a new 8-channel phased-array coil together with a Siemens 3T scanner to develop methods for cardiac MRI.
Jon and Amie’s wedding
March 30th, 2008 by chris
Yesterday, we were thrilled to see Caroline’s brother Jon marry Amie. Their wedding service was held at the church where they both work and was a great testimony to their Christian faith.

Caroline and I were married on 7/7/7 at St Ebbe’s Church, followed by a reception at my then college: St John’s. The day was absolutely splendid and we are very grateful to so many friends who travelled to celebrate with us. Our wedding photos are available online for friends and family to view. Instructions for how to access them are available on request.


DPhil thesis submitted
April 20th, 2007 by chris
At long last, after months of writing, I submitted my DPhil (i.e. PhD) thesis today. It feels great!
I particularly like this photograph that my fiancée took just before I handed it over at Examination Schools, Oxford.
ESR 2007 conference
March 30th, 2007 by chris
We played host to the Royal Society of Chemistry’s ESR group annual conference (”ESR 2007″) here in Oxford this week. I was delighted to be able to talk about my research, and it was great to meet many eminent scientists working on ESR over dinner.
The conference website gives details of the scientific programme and a selection of photographs.
Isle of Man
March 18th, 2007 by chris
This weekend I went to visit an old friend who now works on the Isle of Man. It’s an amazing place and I really enjoyed the chance to escape the DPhil writing up and go and walk up various “bumps”!
This is the arms of the Isle of Man
It was pretty windy in March, although not especially cold. This picture is fairly typical of the coastline
Here are my friend and I at the top of the South Barrule
Split a PDF into separate files containing colour and B&W pages
February 20th, 2007 by chris
The pdfcolour utility allows one to split a PDF file apart to give two separate PDFs, one containing the colour pages and the other containing the B&W pages. That way, one can easily print the B&W pages on a faster, cheaper printer and reassemble the document by hand.
Instructions:
Download the pdfcolour-1.0.tgz file.
Extract it using tar -xzf pdfcolour-1.0.tgz
Recompile if necessary using the command “make”.
Run on a PDF with splitcolour input.pdf bw.pdf colour.pdf
For our American friends, this program will split a PDF into separate color and black/white files.
Find and replace in multiple files using emacs

I found a useful article that explains how one can use emacs to find/replace in several files at once:

Oxford in the snow
February 8th, 2007 by chris

We woke up to a beautiful scene this morning: at our house there was 8cm of snow. Everything was white! Cycling in to town was something of an adventure. I saw this snowman in Hertford College.

Banana, date & walnut cake
January 18th, 2007 by chris
I made this cake (inspired by an internet recipe) this evening. It tastes delicious and is nice and moist inside so I thought I would share the recipe.
Banana, date & walnut cake (Chris’ variation)
Equipment
bowls, scales, electric mixer, microwave, oven, loaf tin
Ingredients
100g dried dates
50g dark rum
175g self raising flour
125 g butter
150g sugar
2 large eggs
4 small/2 large etc but about 300g without skin, VERY ripe bananas, mashed
60 g walnuts
1 tsp vanilla extract
23×13x7cm loaf (2lb) tin, buttered & floured (or it won’t come out!) or paper lined
Recipe
Chop dates into small chunks
Place dates in a small bowl and pour over the rum
Cover and microwave on full power for 1 minute
Remove the lid and let the alcohol boil off
Leave to soak until needed
Turn oven on and set to 180°C (I have a fan oven, adjust temperature to suit yours).
Weigh flour into a medium bowl
In a mixing bowl: soften butter and cream together with the sugar
Beat in eggs one at a time.
Add mashed banana, dates, walnuts and vanilla extract.
Add flour mix, 1/3 at a time, mixing well after each addition.
Pour/scrape into tin. Bake in middle of oven for 50–60 min, until a skewer comes out clean.
Leave in tin on wire rack to cool for 5 minutes before turning out.
Icing
150 g icing sugar
100 g low fat cream cheese
1 tsp cinnamon
Mix together until it has a smooth consistency. Top the cake with this mixture.
N.B. The current icing is too sweet and overpowers the cake a bit. Need to think how to tone it down. Perhaps by adding butter. Perhaps by adding banana to the icing, or lemon juice.
