We went downtown to Joe Patti’s for some fresh fish today. There are quite a few places around here to get fresh fish, but we prefer Joe Patti’s as they seem to have the largest selection.

They are everywhere! I don’t really know where they came from, but there all over my yard. Average height is about 3 feet. The bees and butterflies love ’em. I do too. Hubby hates them and pulls them up, but I think that just makes them spread faster, LOL!

I’ve been wanting to get some insect shots. But it seems that they always came out blurry. I think I got very lucky today. This insect “cooperated” with my camera.

Taking photos in the dark or in low-light settings can be tricky. Just using your normal flash can make your subject look washed out, but not using it can result in a totally dark photo with no subject at all.
This DIY light by professional photographer Simon Ellingsworth of Lightism creates just enough light using glow sticks and PVC pipe for a cheap alternative to expensive commercial options like the ICE Light.
After cutting his PVC pipe to the right length, Simon cut it down the middle lengthwise to remove one side. He drilled a few holes for zip ties to hold the glow sticks, then popped them in place and put the cap on.
Simon used military-grade white light sticks, and he suggests snapping and shaking the sticks before securing them for best results. You could make this as big or small as you need by simply adjusting the size of the PVC and the number of glow sticks you use.
If you can't find any safety light sticks in stores, you could always make your own, though, you'll probably get different results with homemade glow sticks. Try using different colors to get more interesting results.
Oak Ridge National Laboratory's (ORNL's) Cray XT5 supercomputer, Jaguar, kicked off the era of petascale scientific computing in 2008 with applications that sustained more than a thousand trillion floating point calculations per second - or 1 petaflop. Jaguar continues to grow even more powerful as it helps researchers broaden the boundaries of knowledge in virtually every domain of computational science, including weather and climate, nuclear energy, geosciences, combustion, bioenergy, fusion, and materials science.

Oak Ridge National Laboratory's (ORNL's) Cray XT5 supercomputer, Jaguar, kicked off the era of petascale scientific computing in 2008 with applications that sustained more than a thousand trillion floating point calculations per second - or 1 petaflop. Jaguar continues to grow even more powerful as it helps researchers broaden the boundaries of knowledge in virtually every domain of computational science, including weather and climate, nuclear energy, geosciences, combustion, bioenergy, fusion, and materials science. Their insights promise to broaden our knowledge in areas that are vitally important to the Department of Energy (DOE) and the nation as a whole, particularly energy assurance and climate change. The science of the 21st century, however, will demand further revolutions in computing, supercomputers capable of a million trillion calculations a second - 1 exaflop - and beyond. These systems will allow investigators to continue attacking global challenges through modeling and simulation and to unravel longstanding scientific questions. Creating such systems will also require new approaches to daunting challenges. High-performance systems of the future will need to be codesigned for scientific and engineering applications with best-in-class communications networks and data-management infrastructures and teams of skilled researchers able to take full advantage of these new resources. The Oak Ridge Leadership Computing Facility (OLCF) provides the nation's most powerful open resource for capability computing, with a sustainable path that will maintain and extend national leadership for DOE's Office of Science (SC). The OLCF has engaged a world-class team to support petascale science and to take a dramatic step forward, fielding new capabilities for high-end science. This report highlights the successful delivery and operation of a petascale system and shows how the OLCF fosters application development teams, developing cutting-edge tools and resources for next-generation systems.
A question for policy makers is whether U.S. GHG emissions will remain at current levels, decrease to meet the President's 2020 and 2025 goals, or increase to former (or even higher) levels. Multiple factors, including socioeconomics, technology, and climate policies, may impact GHG emission levels. The first section of this report provides current levels and recent trends in U.S. GHG emissions. The second section takes a closer look at some of the key factors that influence emission levels. The third section discusses the challenges in making GHG emission projections by comparing observed emissions with pre-observed emission estimates.

Tax policy is frequently considered by policymakers as a tool for boosting economic performance in various ways, and the likely economic effects of tax policy are often hotly debated. A brief overview of the current economic context is thus a good starting point for looking at tax issues facing the current Congress. This report provides an overview of major tax issues. The report begins by describing three aspects of the economic context in which the tax policy debate during 2004 is likely to occur: the general state of the U.S. economy; the position of the federal budget; and the level ... continued below

Introduction: Technology is a powerful analytic tool. This abstract outlines the use of a custom macro to analyze rat sciatic nerve histology sections as part of a larger study to evaluate functional and histologic outcomes after segmental nerve injury. The problem facing analysis of nerve sections is that the microscopic features of a nerve, such as the individual axon, cannot be viewed on the same scale as the entire nerve bundle. The goal of this analysis was to extrapolate the average total values of axon count, axon density, fiber diameter, and myelin thickness on a nerve section image taken at 400x magnification to the total area captured at 40x magnification.
Methods: Images of nerve sections stained with toluidine blue were captured using a microscope with a mounted camera and image acquisition software (Nikon Eclipse E800; Nikon DS-Ri1; NIS Elements BR 3.10 SP3 Hotfix5). Multiple images at different light intensities were used to determine a contrast and saturation that would grant the best accuracy. From these images, a custom macro using Image-Pro Premier (Version 9.1.5262.28) was developed to compute the desired measurements (Media Cybernetics, Rockville MD).
Results: At 400x magnification, circular shape recognition was used to determine each axon myelin sheath pair in the selected area. Area analyzed was within the “circle of good definition”. After an axon myelin pair was recognized, multiple diameter measurements were taken, and these values were the key to calculations of axon area, fiber diameter, and myelin thickness. Two images taken at 400x magnification for each sample were used to calculate an average for each measurement. An image of the entire nerve slice at 40x was taken, and this calculated area was used extrapolate measurements to the entire nerve section.
Discussion:The utility of this software and macro is exciting due to its reproducibility, accuracy, and efficiency. Not only does it take human processing and potential error out of the equation, but it solves the scale discrepancy when trying to analyze microscopic parameters on a larger scale. This procedure is versatile and can be implemented in future histologic analysis of nerve sections.
