CPP 是啥?

Catalytic pyrolysis process (CPP) is a high-severity catalytic process that has the advantage of maximizing the production of both ethylene and propylene in varying proportions from heavy, low-value feedstocks.

Plastic waste which takes hundreds of years to biodegrade can now be efficiently converted into liquid (crude oil) and vapor hydrocarbons using CPP. There is available technology at present for this that can produce approximately 720 liters of fuel per ton of typical plastic waste. The output oil, or crude oil, can be further processed in a refinery into other value added products or used to power low rpm electric generation turbines.

A 50 - something year old white woman arrived at her seat in a crowded flight and immediately didn't want the seat. The seat was next to a black man. Disgusted, the woman immediately summoned the flight attendant and demanded a new seat.
The woman said, "I cannot sit here next to this black man."
The fight attendant said, "Let me see if I can find another seat."
After checking, the flight attendant returned and stated, "Ma'am, there are no more seats in economy, but I will check with the captain and see if there is something in first class."
About 10 minutes went by and the flight attendant returned and stated, "The captain has confirmed that there are no more seats in economy, but there is one in first class. It is our company policy to never move a person from economy to first class, but being that it would be some sort of scandal to force a person to sit next to an UNPLEASANT person, the captain agreed to make the switch to first class."
Before the woman could say anything, the attendant gestured to the black man and said, "Therefore sir, if you would so kindly retrieve your personal items, we would like to move you to the comfort of first class as the captain doesn't want you to sit next to an unpleasant person."
Passengers in the seats nearby began to applause while some gave a standing ovation.

Vertical vessel

There's an unusual vessel where the height or length (21 m) is much greater than the width (9.8 m). Half of it's vertical tower is above water surface while the lower half is submerged under. This is a design deemed to be very resistant to ocean waves.

It will have research laboratories equipped with  technical equipments, accommodations with necessary appliances, a gym, library, recreation areas and two viewing platforms with a surface-round visibility.

To ensure their effective functioning, it's engines are located on the part that is above the water. However, they produce electricity for the main electric motor which is located on the lower part under the water.

‘Crocs'

Love 'Crocs' footwear?
Well, I don't.

These outrageous stilettos don't look comfy enough for me. Instead, they look so terrifyingly real, look like they could open their mouths and attack at any given moment.

What is USB enumeration?

When you connect a USB device, the system should recognize it and load a proper driver in a process called USB enumeration, but if this fails in OS X, then you might see little or no activity from the device and a repeated message in the OS X console that states the system was not able to enumerate the device.
USB enumeration is a fairly complex process that involves detecting the device, identifying its speed, getting its configuration and description information, assigning port addresses and loading drivers for the device, but to the lay person it essentially means the device is detected and properly loaded for use. If an enumeration error occurs in OS X, the system will try several times to get the necessary information from the device for loading it, but if not then the system will eventually give up.
An enumeration error will generally happen because the device is not working, a driver is corrupt, or a communications error is occurring. In these cases, there are several things you can do to address the problem:

-The device is not working
Try using an external power adapter if the device will accept one to keep from using the less-reliable bus power from the computer. Additionally, the device might need to be reset, which can sometimes be done by unplugging it for a while; other times it may require depressing a special button.

-Corrupt drivers
Try updating the driver from the manufacturer's Web site, or uninstall a previously downloaded one and rely on the generic ones in the device or which shipped with the OS.

-Communications errors
Try unplugging the device and plugging it back in, or try cleaning the cable and the device's contacts to ensure there is proper communication.

You can clean the device's contacts or try using a different USB port on your computer and swap out the cable for a new one, since kinks or other faults in the cable could result in poor communication with the device.
