In this paper we derive a new morphological model, with an extended version of the sediment transport model for mean step length (the average distance travelled by particles), in which depends on bed shear stress. This makes increase increasing flow, line previous experimental results. To account suspension and large-scale turbulent structures rivers, also explicitly water depth. approach enabl...

A 4-day-old boy underwent an urgent operation for mixed total anomalous pulmonary venous connection with the left upper pulmonary vein draining into the innominate vein and the other pulmonary veins draining into the coronary sinus. The left upper pulmonary vein was left uncorrected at that time. After periodical follow-up for 5 years, repair of the uncorrected anomalous pulmonary vein was perf...

Arteriovenous malformations (AVM) are high-flow lesions having a direct connection between an artery and vein, with bypass of the capillary bed.1 Those affecting the upper limb and causing cardiac decompensation are rare. Treatment of such lesions remains a surgical challenge. Despite multiple procedures, total eradication is often not achieved. For some patients, limb amputation becomes necess...

background : upper endoscopy, as an important diagnostic and occasional therapeutic tool is invasive. sedation of patients during the endoscopy procedure with minimal side effects could raise patient tolerability, allowing for ease and increased effectiveness of this procedure. materials and methods: in this study, 105 patients who were candidates for the upper endoscopy procedure were randomly...

Representative ammonites of the Family Heteroceratidae have been studied in this paper. The following forms are recorded from the Koppeh-Dagh Basin: Heteroceras cf. colchicus Djanelidze, Heteroceras spp., Martelites cf. tenuicostatus (Kakabadze), Martelites securiformis (Simonovich, Bastevich and Sorokin), Martelites cf. tinae (Eristavi), Martelites sp.1, Martelites sp. 2, Argvethites sp., Imer...
