A 96-year-old woman developed hemiparesis 2 weeks after orthopedic surgery. Magnetic resonance imaging revealed multiple cerebral infarctions in the bilateral hemisphere. Transthoracic echocardiography revealed a mobile structure attached to the anterior mitral leaflet that protruded toward the left ventricular outflow tract. The structure was identified as an accessory mitral valve. Doppler ec...

A 46 year old man was found to have left ventricular outflow obstruction caused by a blood-filled cyst attached to the anterior papillary muscle of the mitral valve. It was successfully excised.

vegetation cover on a variety of different land uses in different parts of a city creates different forms of heat flow that this, in turn, generates the main framework of urban microclimate. the objective of this study is to survey the effect of land cover type on air temperature in the isfahan city. to do this, five regions in the isfahan city with different land cover type were selected. in e...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

A hydraulic fluid impedance plot is produced by plotting instantaneous differential pressure against phasic blood flow across a vascular segment. This simple plot quantitatively and compactly describes the changes in flow resistance (impedance) throughout the entire cardiac cycle. Impedance plots were obtained before and after corrective surgery in patients with a variety of left ventricular ou...

there are different materials and compounds in water that determine its chemical and physical quality. as the result of special conditions such as increase and decrease in discharge, water quality can vary. one of these conditions is drought that decreases discharge, and water quality changes. in this study, droughts of sistan and baluchistan province have been analyzed using standardized preci...

This study used the standardized precipitation index (SPI) and runoff (SRI) to analyze dry humid conditions in hill-country catchment area of Laborec River (Slovakia) over a period 50 years (1970–2019). Analysis SPI SRI various time scales showed occurrence wet periods (index > 1.0) that were associated with exceeding long-term norm, below −1.0), which result small amounts precipitation. cor...

In Algeria, only the transport of suspended sediment is measured, rate bedload in global solids estimated, approximately. Measures bed load field are very costly, due to flow disturbances. As a result, evaluations this type difficult carry out absence databases. article, we tried quantify mode at wadi El-Hammam using formula Meyer-Peter and Müller. Formula that seems best adapted physical chara...
