Electronic structure of CeRu4Sn6: a density functional plus dynamical mean field theory study

The Kondo system CeRu$_4$Sn$_6$ shows a strong anisotropy in its electric, optic and magnetic properties. We employ density functional theory plus dynamical mean field theory and show that the predominant Ce-$f$ state has total angular moment $J=5/2$ and $z$-component $m_J=\pm 1/2$ in agreement with recent X-ray absorption experiments. Even though CeRu$_4$Sn$_6$ has the direct gap of a Kondo insulator through most of the Brillouin zone it remains weakly metallic. This is because of (i) a band crossing in the $z$-direction and (ii) a negative indirect gap.Comment: 6 pages, 9 figure

A Review of the Benefits of Flax Supplementation

We have become a society of convenience. Healthy foods that were staples for thousands of years have become replaced by processed foods with long shelf lives. This has been done to the detriment of our nutrition and health. Flax is one such replaced food item. A staple food for hundreds of generations, flax had become scarce in our diet until recent interest spurred by research found flax to be one of the best sourc es on earth for alpha-linolenic acid an Omega- three fatty acid, plant lignans, and contains a large amount of dietary fiber. Potentially these constituents can have great health benefits for many health disparities such as cardiovascular disease including hypercholesterolemia, as well as, conditions such as cancer, inflammation, and bowel regulation. The purpose of doing this review is to identify the proven benefits of flax supplementation to use in primary care. The main search engines used to search the literature included PubMed, CINAHL, and Google Scholar. The literature shows flax supplementation has proven LDL cholesterol lowering benefits, bowel regulation benefits, inflammatory marker reduction, and enormous potential for further research in many other areas. For this reason it is appropriate in primary practice to support flax supplementation to promote normal cholesterol levels, and for bowel regulation
