we can surfing on the Internet whenever we like without opening a computer.Whats more, we are imformed of everything important when we carry our cell phone all the time. Futermore, it can also help us with some learning,beacuse we can look up the word in the digital dictionary...
The wavelengths of the light we can see range from 400 to 700 nanometers (or billionths of a meter). But the full range of wavelengths included in the definition of electromagnetic radiation extends from 0.1 nanometers, as in gamma rays, to centimeters and meters, as in radio waves. ...
Thanks to aerogel's unique structure, its use as an insulator is a no-brainer. The super-insulating air pockets with the aerogel's structure almost entirely counteract the three methods of heat transfer: convection, conduction and radiation [source: Cabot Corporation]. Even though aerogel is stil...
its eerie clicks signifying the presence of dangerous ionizing radiation. More recently, doctors embraced sound to indicate specific medical readings; the beep-beep of an electrocardiogram is perhaps the most iconic (unless you count Monty Python’s medical device that goesbing!). Current applications...
Arguably, this account is spuriously elaborate. It might seem simpler and clearer to account for peroratives as one of the many kinds of indirection that can be housed in the category of a speaker’s perlocutionary force; then we would be done.Footnote10But the considerations assembled here hi...
Microwaves are a type of wave sandwiched between radio waves and infrared radiation on the electromagnetic spectrum. In the case of microwave ovens, the commonly used wave frequency is roughly 2,450 megahertz (2.45 gigahertz). Waves in this frequency range have an interesting property: Water, ...
Surgery Can Cause Erectile Dysfunction Surgical or radiation treatments for prostate cancer, bladder cancer, or prostate enlargement (BPH) can sometimes damage nerves and blood vessels near the penis. Occasionally, the nerve damage is permanent and the patient requires treatment to achieve an erection....
biomolecules between drug-resistant and drug-sensitive cells, resulting in altered gene expression in the recipient cell. Under hypoxic conditions, EVs can release miRNAs like miR21 and miR-301a, which can decrease recipient cell sensitivity to cisplatin and/or promote radiation resistance [236,237]...
This trading of heat can happen three different ways: by convection, conduction, and radiation.热量的传递通过三种方式进行：对流、传导和辐射。All three are at play in an igloo.冰屋里面，热量传递的这三种方式都实现了。A person inside will radiate body heat, which moves around the igloo by ...
