What Should Be Considered When Simulating Doppler Velocities Measured by Ground-Based Weather Radars?

Emergent Colorectal Surgery: What Should Be Considered?

In emergent settings for the treatment of colorectal diseases, diverse complications, including obstruction, perforation, ischemia, and sepsis, contribute to the high risk of both mortality and morbidity in comparison to scheduled settings. According to Western studies, the mortality and the complication rates are high in such cases, ranging from 10% to 25% and 30% to 50%, respectively [13]. Ho...

How should tissue Doppler tracings be measured?

Tissue Doppler, an echocardiographic modality measuring velocities of solid cardiac structures by pulsed-wave or colour Doppler, after very early experiments was introduced clinically in the early 1990s and is one of the very few recent technical innovations in echocardiography to gain quick and near-ubiquitous clinical implementation. The most widely adopted application is the registration of ...

Staphylococcus lugdunensis; a pathogen that should be considered in Iran

Background: Staphylococcus lugdunensis is Gram-positive cocci of the staphylococcaceae family. S. lugdunensis despite having a clotting factor (wall coagulase), was classified in the coagulase negative staphylococcus group (CoNS) for lack of free coagulase. Although this bacterium is part of the human normal flora, in terms of virulence, S. lugdunensis is in second place after S. aureus. S. lug...

Doppler Weather Radars and Wind Turbines

In many countries the number of wind turbines is growing rapidly as a response to the increasing demand for renewable energy. The cumulative capacity of wind turbines worldwide has shown a near 10-fold increase in the last decade (Global Wind Energy Council, 2011) and in the coming years many more wind turbines are expected to be built. Existing, older wind turbines are likely to be replaced by...
