Signing Up Time for Summer Four Seasons Dolls Quil. WIP Wednesday Week 17 - green binding. Todays Outing to the Craft Fair/Quilt show!. WIP Wednesday - Week 18 - Caitlins hanger. Looking at it now laying on the floor, I am thinking just a nice green block in the middle, that should pop out! Not that it matters, just a quirk of the design. Each block has 2 sections of the same print. I only had 8, I thought I cut 9 bits of fabric! It should be a different print in each section of the block, but I have doubled up on these. However I did encounter a problem when I got to the end stage and laid my blocks out on the floor. Because its a lot of slicng and dicing it comes together really quickly and even more so if you sew all the blocks together at the same time. Starting to look interesting now! Add some more white sashing between these two bits.Īnd another slice, starting to get why its called a slice and dice?Īnd wolah! This is what my final block looks like! You can get tricky, you don't have to do 3 slices each side, you could do 4. I found it better to do these ones one at a time and just placed one bit already cut on the top and used that as a guide for the ruler.Īnd another mix up of the prints. Sewn together and ready to rotate 90 degrees!Īnd another big slice! Just be careful doing these ones, cause the rotary balde can pull it off a bit cause you are cutting through so much fabric. You could get imagainative and use different colours each time too. You get out the rotary cutter again and cut another angle.Īgain, you mix up the prints and I'm putting a white sashing inbetween to make it a square again. Now the fun bit, you mix up the prints, dice them up! Here I am adding the white sashing between the two sliced peices, 1 inch wide here but that is up to you the width. Nice and strong cause there is a few layers there to get through. So you place the 9 peices of fabric on top of each other, get out your ruler and rotary blade then give them one big slice. These ones here are 10 inch square, I figure that will come down to maybe 8 inches and so with seam allowances, 7.5 inches on the finished quilt top. Now the finished block size will be smaller as its a wonky sew along. Why not hey? Anyone up for a sew along? I have abandoned my original design of having green/blue blocks and contrasting blue/green sashing, instead I have gone for white! You could add a sashing like here or not, up to you! Here we go.įirst up you need 9 squares of fabric. Slice it stage 12 mp4#

How about take a photo of each stage of a dice and slice block and blog it as a tutorial. The 2D detector, at a distance z = 62 cm behind the sample, consists of a scintillator, converting X-rays into visible light, followed by a mirror, a lens, and a complementary metal oxide semiconductor (CMOS) camera (effective pixel size Δx = 2.2 µm). laevis embryo immersed in buffer solution and suspended by agarose) mounted on a rotation stage for tomographic data acquisition. After beam shaping and monochromatization, X-ray wave fronts propagate over a distance d (∼50 m) to impinge on the sample (living X.

By analysing individual cell trajectories, collective tissue motion and the evolution of morphological features, the authors visualize known gastrulation movements and reveal the formation of a transient ectodermal ridge structure not reported on previously. Julian Moosmann, Ralf Hofmann, Jubin Kashef & their colleagues (Karlsruhe Institute of Technology), Xianghui Xiao (Argonne National Laboratory, IL), Alexey Ershov (National Research Tomsk Polytechnic University) and Maneeshi Prasad & Carole LaBonne (Northwestern University, IL) developed a non-invasive in vivo time-lapse phase-contrast X-ray microtomography technique which allows the observation of gastrulation.
The study of gastrulation in Xenopus, the stage at which the embryo has formed three layers arranged around a central cavity, has been hampered by the lack of high-quality live-imaging methods useable on intact Xenopus embryos, which are opaque at early stages.
