In particular, I am very much interested in the flow-curve of saliva that is available in <a href=\"http:\/\/rsif.royalsocietypublishing.org\/content\/14\/127\/20160764\">this paper<\/a>.<br \/>\nTo me, this flow-curve is quite exceptional.<\/p>\n<p>There are many shear-thinning fluids for which the viscosity decreases with increasing shear rate. For instance, mayo is such a fluid. If mayo is put on a dish and the deformation rate is low, mayo keeps its shape and not that flowing. On the other hand, if mayo is stirred in a bin and the deformation rate is high, it is less viscous than honey, for example. Such a material behavior is so-called shear-thinning.<\/p>\n<p>The flog saliva is a shear thinning fluid. But the shear-thinning property is unusual. The viscosity drastically changes in a narrow range of shear rate. Both sides of this critical shear rate window, the viscosity does not depend on shear rate.<\/p>\n<p>Very interesting. I like this study much, in particular due to the fact that they collected amount of flog&#8217;s saliva for the measurements&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Take a look at the ver [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1,19],"tags":[],"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/posts\/949"}],"collection":[{"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/comments?post=949"}],"version-history":[{"count":1,"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/posts\/949\/revisions"}],"predecessor-version":[{"id":950,"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/posts\/949\/revisions\/950"}],"wp:attachment":[{"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/media?parent=949"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/categories?post=949"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rheology.jp\/nagoya\/wp-json\/wp\/v2\/tags?post=949"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
