Since You Need A Green Light
Truth is subjective.If there is one word of advice I would leave to my children it would be, you're better off being DIFFERENT. If the majority of people are doing something and you choose to be a part of it then you're probably on a fast track to self-destruction.
One of these disturbing changes I mentioned is the fact that my fellow oxvgen users allow themselves to be fooled so easily. It's almost as if no one can think on their own anymore.We let trends influence how we dress, talk and interact. Where I'm from, in the 90's you couldn't be caught dead with tight pants. Now, a couple of rap artist wear "skinny jeans" and it's okay? Now I'm not saying that there's anything wrong with wearing fitted clothing, but does media have to give you a green light for everything? Live your life for you.
Have you ever asked yourself, who defines your perspective of "cool?" When you see a commercial on TV advertising some new shoes that aren't economically friendly,are you interested in the actual design of the shoe or are you more concerned about how you are perceived wearing an expensive brand?
Currently,we seek that peace in the wrong places. Did you know that it's human nature to desire to be a part of something? Do you really want to be out all night drinking with the guys/girls? Who celebrates turning 33 with shots? Choose to be a part of something positive. Constantly seek to better yourself and your circle.
Life can be discouraging at times. We subconsciously corner our souls until the point where we have to escape by any means necessary. Even to the point of doing things we wouldn't normally do. Reaching the bottom of a 750ml bottle of Ciroc (a brand of alcohol)could be emotional survival. Same goes for participating in drugs and other escapes we've created.It's past time to wake up from your slumber(睡眠)。
Find your happiness. Not the temporary satisfaction from substance--less material things. Take a break from consulting your many Facebook psychologists. Think on your own for a change. Evaluate your current status and plan for where you want to be.

Thomas Wallin at Cornell University in New York and his colleagues have created soft robotic grippers(机械爪)that are capable of sweating to cool down.
The grippers are capable of a cooling capacity of 107 watts per kilogram,making them more efficient sweaters than mammals.By comparison,humans and horses have a maximum cooling capacity around 35 watts per kilogram.
Each gripper consists of three finger-like parts that bend simultaneously(同步地)to grasp small objects.The 3D-printed grippers are made from hydrogels -materials which can store large amounts of water.Each finger is made from an underlayer with an internal channel to let fluid flow and is capped with a surface layer containing micropores(微孔)。
At cold temperatures,the pores close.At temperatures higher than 30C,the surface layer expands,enabling pressurised fluid from the underlayer to sweat out.The material responds simultaneously to temperature changes without the need for external sensors.
"Sweating takes advantage of evaporative water loss to rapidly dissipate(使消散)heat,”said Wallin in a press briefing yesterday.Unlike convection or radiation,sweating lowers the temperature of a body below that of its environment,he said.
"When the local temperature rose above the transition,the pores would simply open on their own,"said Wallin.
When blown by wind from a fan,the sweating robots cooled at a rate of 39.1C per minute, about six times faster than similar devices that are unable to sweat.The technique could be used to help robots operate for long periods of time without overheating,said team-member Robert Shepherd,also at Cornwell.
However,there is currently no means for the robot to replenish(补充)its fluid stores after sweating.This means"the robots that operate via the autonomous sweating that we've created would have to also be able to drink",said Shepherd.
1.What is the most distinct feature of soft robotic grippers?
A.They can cool themselves down by sweating.
B.They can grasp objects like human fingers.
C.They can store large amounts of water.
D.They're 3D printed and can bend.
2.What is the fundamental principle behind the sweating of robotic grippers?
A.Three parts of each gripper bend at the same time.
B.The external sensors detect the temperature change.
C.Heat expands the material and squeezes the liquid out.
D.Radiation lowers the temperature below the environment.
3.We can conclude from the last paragraph that the robots
A.can sweat by themselves
B.need to be refilled with water
C.can sense thirst and drink water
D.can work long without overheating
Project Puffin, Skomer, Pembrokeshire
Passionate about wildlife and nature? These surveys and activities offer volunteers a close-up of our fauna (动物群)and flora (植物群)while helping to safeguard the environment. Plan ahead for next summer and join the "puffarazzi" with the RSPB. Between early June and late July 2020,visitors to the UK's puffin (善知鸟)colonies will be asked to take photographs of birds with fish in their bills, making a note of the date, time and location and then uploading that information to a dedicated page on the RSPB 's website. The idea is to help conservation scientist Dr Ellie Owen and her team pinpoint why puffin colonies are declining (the current thinking is that it is related to a reduction in food availability caused by climate change). The colonies include Skomer Island, in Pembrokeshire, to which the Wildlife Trust of South&West Wales runs day trips between Easter and the end of September. |
Boat fares from Martin's Haven to Skomer are £11 adult, £7 child, landing fee £11 adult, £5 child. Hostel-style overnight stay £30 adult, £15 child. Details of Project Puffin at rspb.org.uk |
