It, along with tachypnoea, is a marker of acuity, not hypovolaemia. There is little data to support the use of capillary refill time (CRT) in adults and the normal value of fewer than 2 seconds is an arbitrary
What is OpenGL? 什么是 OpenGL? 在最基本的层面上,OpenGL 是一个允许程序员与图形硬件通信的软件接口(software interface)。当然,OpenGL 的内涵远不止于此,你会很高兴知道本书将为你讲解 OpenGL 的更多细节。不过,在我们动手开始编码之前,你需要了解一下计算机图形学(Computer Graphics)和 OpenGL 的历史。 在这篇...
1897 年,费迪南德·布劳恩(Ferdinand Braun)在德国发明了 CRT(阴极射线管 Cathode Ray Tube),这是一种真空管,其目的是在屏幕上显示图像。你可能见过或使用过显像管电视和计算机显示器,它们一直是主流,直到最近。 阴极射线显像管已被用于电视和示波器输出,但没有人想到要将这种技术与计算机结合起来。第一次使用显像管...

Heart Failure (HF) is one of the leading problems in cardiology practice today. Acute decompensated heart failure (ADHF) is a significant caus
Osteoarthritis is the most common joint disease; in the near future, it is projected to rank second for women and fourth for men in the developed countries in terms of years lived with disability [1]. Elderly patients are most often affected (joint diseases account for half of all chronic ...
process under examination. We assume that since AQPs are ubiquitous, they must have an important function and suggest that this is the detection of osmotic and turgor pressure gradients. A mechanistic model is proposed—in terms of monomer structure and changes in the tetrameric configuration of ...
