talon cusp is a dental anomaly also known as an eagle’s talon. it is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. the exact etiology is unknown. the incidence of talon cusp is less than 6%. commonly involved teeth are maxillary incisors, usually unilateral but in some instances bilateral. the classical ra...

Weather forecasts are nearly always portrayed from either a satellite view perspective, a numerical or symbol based representation. None of these methods actually portray weather visually from the point of view of the observer, that is, they do not represent our experience of weather. This problem presents a challenge to displaying weather using real-time 3D computer graphics. 3D Weather is a p...

Abstract   Bicornuate uterus is class IV and septate uterus is class Vin uterine anomaly classification. Bicornuate uterus is almost always treated by laparotomy and metroplasty. But the treatment of choice for septate uterus is hysteroscopic metroplasty. Bicornuate- septate uterus which is described in this paper is a new class of uterine anomaly(between class IV & V). The advantages of hyster...

​Congenital anomalies of the coronary arteries have been a known subject  since the advent of cardiac angiography, and has been a subject of special interest by both cardiologists and cardiac surgeons,  We have tried in this article to present a case of anomalous origin of LAD from RCA (RMT) in a 55 year old lady (Mrs. B.J.) and to completely dis­cuss this subject. It's worthmentioning that thi...

There are two reasons why tropical weather is different from that at higher latitudes. The sun shines more directly on the tropics than on higher latitudes (at least in the average over a year). This makes the tropics warm. And, the vertical direction (up, as one stands on the earth’s surface) is perpendicular to the earth’s axis of rotation at the equator, while the two are the same at the pol...

in this paper, an improved method (improved an-eul) is presented. this method is based on the combination of the analytical signal and the euler deconvolution method. two important parameters such as location and approximate geometry of a magnetic source can be obtained using the conventional an-eul method. altitude of ground and height in upward continuation has been considered for depth deter...

in order to recognize isfahan weather types, in this research 22 variables including temperature, precipitation, atmospheric humidity and wind were studied in isfahan synoptic station from dey,11th,1339(january,1st,1960) to dey,11th,1383 (december,31st,2004). a cluster analysis on the euclidean distance of standardized matrix of data and linking days on the basis of ward method showed that isfa...

The paper describes an algorithm for constructing convective weather avoidance polygons. The algorithm combines weather avoidance fields (WAF) from the en route convective weather avoidance model (CWAM) with edges automatically detected in the echo tops field, clustering, convex hull fitting and wind data to build weather avoidance polygons. Results for 2 case days with significantly different ...

Abstract. In the Northern Hemisphere, recurrence of transient synoptic-scale Rossby wave packets in same phase over periods days to weeks, termed RRWPs, may repeatedly create similar surface weather conditions. This can lead persistent anomalies. Here, we first demonstrate significance RRWPs for hot spells Southern Hemisphere (SH) using ERA-Interim (ERA-I) reanalysis dataset and then examine ro...

Abstract Correcting the forecast bias of numerical weather prediction models is important for severe warnings. The refined grid requires direct correction on gridded products, as opposed to correcting data only at individual stations. In this study, a deep learning method called CU-net proposed correct forecasts four variables from European Centre Medium-Range Weather Forecast Integrated Foreca...
