Computational modelling is helpful for elucidating the cellular mechanisms driving biological morphogenesis. Previous simulation studies of blood vessel growth based on the Cellular Potts model (CPM) proposed that elongated, adhesive or mutually attractive endothelial cells suffice for the formation of blood vessel sprouts and vascular networks. Because each mathematical representation of a mod...

Laser photocoagulation of the feeder vessels of age-related macula degeneration-related choroidal neovascularization (CNV) membranes is a compelling treatment modality, one important reason being that the treatment site is removed from the fovea in cases of sub- or juxtafoveal CNV. To enhance the energy absorption in a target feeder vessel, an indocyanine green dye bolus is injected intravenous...

A great number of collision accidents can be attributed to incongruous collision-avoidance actions between the give-way vessel and stand-on in a crossing or overtaking situation. If does not take appropriate action according international regulations for preventing collisions at sea, last barrier pass safely is effective taken by vessel. To find proper autonomous vessel, method proposed that co...

Pressure vessel is a container used to store fluids under pressure and temperature. The fluids can be air, water, chemicals, fuel, gases etc. are most commonly used in food and chemical industries, oil refineries and so on. Pressure vessel is subjected to thermal and structural loads for power plant applications. Since the pressure vessel are subjected to both structural and thermal loads stres...

The dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

in this paper, we describe a case of an aneurysmal circumflex artery connected to the coronary sinus through a fistula in a 40-year-old man with a two-year history of palpitation and chest pain. we discussed surgical management for patients with coronary artery fistula (caf), particularly for asymptomatic patients with a small left-to-right shunt .

anomalies of origin, course, and distribution of coronary arteries, including single coronary artery, are well known in patients with tetralogy of fallot. however, to the best of our knowledge, there is no published case report of pentalogy of fallot with a single coronary artery. herein, we introduce a 22-year-old female patient diagnosed via echocardiography and cardiac catheterization preope...

a 48-year-old woman was admitted to the emergency department with complaints of typical chest pain, cold sweat, and dyspnea of 24 hours’ duration. she had a history of hypertension, hyperlipidemia, and diabetes mellitus for many years. on admission, her electrocardiogram (ecg) revealed normal sinus rhythm and dynamic t inversion in the precordial leads. her enzyme levels were normal. transthora...

By using the developed finite-element models, we perform numerical investigation of nonstationary temperature fields and kinetics microstructural phase transformations in base material WWER -1000 reactor vessel (15Kh2NMFА steel) under conditions submerged-arc cladding protective anticorrosion layers austenitic materials. We comparative analysis results simulation obtained by two methods predict...
