Two common types of barriers used to protect against floodwaters are levees and floodwalls. Levees are earthen embankments that help redirect water away from vulnerable areas, while floodwalls are typically made of concrete and provide a more robust barrier against rising waters. Both structures are designed to minimize the impact of flooding on communities and infrastructure. Additionally, temporary barriers like sandbags can be used for quick protection during emergencies.
To reduce erosion by the shore, people can build structures such as seawalls, which act as barriers to protect the coastline from wave impact. Additionally, groins can be constructed to trap sand and widen beaches, while vegetative buffers made of plants can help stabilize the soil and absorb wave energy. Beach nourishment, which involves adding sand to eroded beaches, is another effective method to combat shoreline erosion.
Assuming you mean "Is an engineer considered as professional as a doctor?", then yes. This would only apply to actual engineers though; there are a lot of people who call themselves engineers when really they're technicians, draftsmen etc. It would be like a nurse calling themself a doctor.
Thermal means 'temperature' and 'environment' means that which surrounds you. Temperature would include the ambient heat of the air, hot/cold surfaces and sources of thermal radiation. Wind chill would also be a factor to consider. Therefore the 'thermal environment' means the temperature of your surroundings and these would change and present different risks depending on where you were. For instance if you were at the North or South pole you would be in danger of freezing to death. Standing by a lava flow or near a forest fire, you would be in danger of burning to death. People normally protect themselves from thermal discomfort by means of the cloaths they wear or by heating or cooling the buildings they live in. People placing themselves in thermal extremes (hot or cold) would take specialist precautions - fireman's suits or survival suits. Finally sunbathers would protect themselves form the sun by covering up and using sun cream.
The electronics are very small and im not sure if the technology today is able to make them so small.Secondly,Think about if there we nanobots in bloodstream to protect from diseases.If someone was to gain control over them people who have them would have to cooperate or could be killed
I do not think you understand what a hacker is. They do not protect people. Hackers are curious about and investigate the internal structure of computer programs and systems and how they work by studying the code. In doing so they also can discover loopholes and faults in programs that can be exploited for personal gain at the expense of computer users. Reporting such faults to the program developers often results in better programs and a safer computer experience for users. Sometimes the developers feel that the found faults are not cost effective to repair. Hackers making the problems public forces them to publicly acknowledge the issue and hopefully fix them. At the least, making the public aware of such problems steers people away from using the defective programs.
stay away from earth away from people
they build flood gates and barriers to protect houses
