BACKGROUND Arrhythmic mitral valve prolapse (MVP) is characterized by myxomatous leaflets and left ventricular (LV) fibrosis of papillary muscles and inferobasal wall. We searched for morphofunctional abnormalities of the mitral valve that could explain a regional mechanical myocardial stretch. METHODS AND RESULTS Thirty-six (27 female patients; median age: 44 years) arrhythmic MVP patients w...
We consider the curling of an initially flat but naturally curved elastica on a hard, nonadhesive surface. Combining theory, simulations, and experiments, we find novel behavior, including a constant front velocity and a self-similar shape of the curl that scales in size as t(1/3) at long times after the release of one end of the elastica. The front velocity is selected by matching the self-sim...
Geminiviruses are a group of plant viruses that contain circular single stranded (ss) DNA genomes encapsidated in small twinned icosahedral capsids .The virus DNA A plus strand encodes the coat protein (CP/AV1) essential for viral transmission by whiteflies (Bemisia tabaci)[4]. Jatropha has been found to have strong molluscicidal activity and the latex to be strongly inhibitory to watermelon mo...
rosy apple aphid, dysaphis plantaginea (passerini), with worldwide distribution is an important pest of apple orchards. host plant resistance is an essential component of integrated management of this insect pest. we investigated the resistance of seven apple cultivars, malus domestica (borkhausen), namely granny smith, starkrimson, golden smoothee, red delicious, golden delicious, boshghabi, a...
peanut plants showing mottling, yellow and necrotic spots on leaves were collected from peanut fields in golestan province. electron microscopic studies revealed the presence of flexuous filamentous particles ca. 700 nm in length, which was suggestive of a potyvirus infection. healthy nicotiana benthamiana plants mechanically inoculated with sap from infected peanut plants showed mottling, down...
When sailing downwind with a spinnaker, the “verge of curling” is one common recommendations that sailors follow for efficient sailing. Wind tunnel experiments on spinnaker models conducted by Aubin et al. (2017) in Twisted Flow Tunnel Yacht Research Unit University Auckland have shown curling can be related to better performance at Apparent Angle ≥ 100°. In present article, we will focus aerod...
