A supressão da vírgula empregada logo após o vocábulo “Assim”, que inicia o segundo período do segundo parágrafo, manteria a correção gramatical, embora alterasse o sentido original do texto.
Seria mantida a correção gramatical do texto caso o trecho “pelo qual” (primeiro período do primeiro parágrafo) fosse substituído por porque.
Considerando-se as ideias de Platão e Sócrates apresentadas no texto, é possível concluir, se se acredita que pessoas que operam sua vivência unicamente a partir de redes sociais vivem de aparências, que tais pessoas não conhecem a Verdade.
O termo “Alegoria”, empregado no texto precedente, alude à ideia de representação.
O pronome “este”, na expressão “De acordo com este texto”, que inicia o segundo parágrafo, remete a toda a ideia contida no parágrafo anterior.
Depreende-se do texto que as visões de Sócrates e Platão convergem ao relacionar a justiça ao conhecimento do Bem.
Dado o fato de o vocábulo “mas”, em sua primeira ocorrência no segundo período do primeiro parágrafo, ter sido empregado com sentidos adversativo, de oposição, os sentido originais do texto seriam mantidos caso ele fosse substituído por porém.
Nos fluidos em escoamento, podem estar presentes diferentes tipos de força: inércia, viscosidade, pressão, gravidade, tensão superficial e compressibilidade. A razão entre duas dessas forças quaisquer será adimensional.
Um importante adimensional é o número de Reynolds (Re), que relaciona forças de inércia com força(s) de
NASA’s Nuclear Frontier: The Plum Brook Reactor Facility
There are three main types of nuclear reactors: power, research, and test. Research and test reactors as scientific tools are more common than most people realize. While power reactors frequently appear in newspaper headlines and are conspicuous because of their size and power, research reactors can be quietly tucked away, even in the midst of a college campus. Power reactors generate heat, which can easily be converted to other useable forms of energy, such as electricity. Research reactors operate at very low thermal power levels – so low, in fact, that they do not even require any type of forced cooling. They are used to measure nuclear parameters and other characteristics, which can then be used to build other reactors or to design experiments for test reactors. Test reactors are more powerful than research reactors and are able to produce much more intense radiation fields. Though they are still much less powerful than the power reactors, they generate enough heat to require a closed-loop forced-circulation coolant system. This system will remove the heat from the reactor by transferring it to a secondary cooling system, which releases it into the atmosphere through cooling towers.

O marciano encontrou-me na rua e teve medo de minha impossibilidade humana. Como pode existir, pensou consigo, um ser que no existir põe tamanha anulação de existência?
Afastou-se o marciano, e persegui-o. Precisava dele como de um testemunho. Mas, recusando o colóquio, desintegrou-se no ar constelado de problemas.
E fiquei só em mim, de mim ausente.

Some of you may be familiar with OSHA - the Occupational Safety & Health Administration. The sole purpose of this agency is to keep American workers safe. Complying with OSHA regulations isn't always easy, but if we work together, we can do it. Yet, complying with regulations is not the real reason for working safely. Our real motive is simple. We care about each and every one of you and will do what is necessary to prevent you from being injured.
However, keeping our workplace safe takes input from everyone. Management, supervisor, and all of you have to come together on this issue, or we're in trouble. For example, upper management has to approve the purchase of safe equipment. Supervisors, including myself, have to ensure that each of you knows how to use that equipment safely. Then it's up to you to follow through the task and use the equipment as you were trained. If any one part of this chain fails, accidents are going to happen and people are going to get hurt.
Responsibility Number One - Recognize Hazards
At the core of your safety responsibilities lies the task of recognizing safety and health hazards. In order to do that, you must first understand what constitutes a hazard. Extreme hazards are often obvious. Our hopes are that you won't find too many of those around here.
There are, however, more subtle hazards that won't jump up and bite you. As a result of your safety training and meetings like these, some things may come to mind. For example, a machine may not be easy to lock out. Common practice may be to use a tag. This is a potential hazard and should be discussed. Maybe something can be changed to make it easier to use a lock. Other subtle hazards include such things as frayed electrical cords, a loose machine guard, a cluttered aisle, or maybe something that just doesn't look right.
Responsibility Number Two - Report Hazards
A big part of recognizing hazards is using your instincts. Nobody knows your job as well as you do, so we're counting on you to let us know about possible problems. Beyond recognizing hazards, you have to correct them or report them to someone who can. This too, is a judgement call. For example, if something spills in your work area you can probably clean it up yourself. However, if there is an unlabeled chemical container and you have no idea what it is, you should report it to your supervisor.
Additional Employee Responsibilities
Good housekeeping is a major part of keeping your work area safe. For example, you should take a few minutes each day to ensure that aisles, hallways, and stairways in your work area are not obstructed. If boxes, equipment, or anything else is left to pile up, you have a tripping hazard on your hands. Those obstructions could keep you from exiting the building quickly and safely should you face an emergency situation.
Also watch out for spills. These can lead to slips and falls. Flammable materials are another thing to be aware of. Make sure they are disposed of properly.
Keep Thinking. Even if you're doing your job safely and you are avoiding hazards, there are often even better ways to work safely. If you have ideas for improving the safety of your job or that of co-workers, share them.
Concluding Remarks
While nothing we do can completely eliminate the threat of an incident, we can work together to improve our odds. As I said, this must be a real team effort and I'm counting on input from all of you. Let's keep communicating and continue to improve safety.
