Inner canthal or palpebral arteriovenous malformations (AVMs) are uncommon and difficult lesions to treat if isidor oreiller they are of high-flow type.Though they may present with mainly cosmetic reasons, they derive feeders from the ophthalmic artery and are associated with dangerous anastomoses.Percutaneous liquid embolic agent has been used to
Rest pools provide a rest place for migratory fish to swim upstream,so whether its flow pattern is reasonable or not directly affects the upstream efficiency of fish.Based on the design principle of the mainstream centered in the pool,this paper builds a three-dimensional numerical model to optimize the shape of the vertical slot fishway rest pool,
We describe a new species of frog of the genus Zakerana discovered from the urban core of Dhaka, Bangladesh, one of the most densely populated cities in the world.Although the new species is morphologically similar to the geographically proximate congeners in the Bangladeshi cricket frog group, we show that it can be distinguished from all congener
Cardiovascular diseases (CVDs) are the deadliest diseases worldwide.Master-slave robotic systems have been widely used in vascular interventional surgery with the benefit of high safety, efficient operation, and procedural facilitation.This paper introduces a remote-controlled vascular interventional robot (RVIR) that aims to enable surgeons to per
Background: There are a number of ways in which one can sustain a head injury.Even if you are doing simple household activities or going out for a morning walk, you cannot be sure of what type of injury awaits you.The source of injury may be a pressure cooker whistle acting as a projectile or a hailstone falling from the sky.Such injuries are commo
