When facing with difficulty in equipment delivery or even entrapment, pulling back strongly or a hard push were not recommended. Take a closer look and figure out the mechanism behind the failure is crucial to a successful procedure. Besides, abrupt vessel closure is a troublesome and sometimes ...
When we’re talking about exposure in photography, a stop is a measurement of an exposure, depending on either the shutter speed, the ISO, or the aperture. To be specific, if you were to increase the exposure by one stop, you would be doubling the exposu
In order to increase the sensitivity of a bolometer, its temperature needs to be cooled to a fraction of absolute zero. Initially, an a-Si microbolometer was created by Texas Instruments. Texas Instruments had leading-edge CMOS technology at the time. But a -Si microbolometer's impedance is ...
If you want to experiment before investing in a dedicated macro lens with a focal length better suited to the style, you can get a reversing ring for a fraction of the cost. This allows you to mount a regular lens backward on your camera to create a macro effect. ...
innovation for astronomy. For most other producers eyepieces represent only a small fraction of the business. I’m sure Vixen, Pentax, Nikon etc have optical designers comparable to Al Nagler or Paul Dellechiaie, but those guys are small kogs in big machines. Good enough is good enough for...

While the full mechanism is yet unclear, BT’s impact appears varied, going beyond decreasing the airway smooth muscle (ASM) and reticular basement membrane thickness in the proximal and distal airways. There is evidence of reduction in epithelial neuroendocrine cell, ASM-associated nerve, and submu...
