Different pollutants released from the vehicles would cause different impacts to the human body. The first one is Nitrogen oxides (NOx). When the fuels are burning at a very high temperature combined with the electric sparks in the vehicles causing the nitrogen and oxygen in the atmosphere combined together but then the formation of nitrogen oxide will react with the oxygen to form nitrogen dioxide(NO2) rapidly. If people inhaled a low level of NO2‚ the gas will irritate your eyes‚ nose‚ throat‚

Before Surgery in the early 19th century is dangerous and painful. There is no way to relieve the pain felt by patients during operations. Surgeons do not yet know how to control blood loss or infection‚ and operating theatres are dirty and dangerous places to be.Some surgeons superstitiously prefer to wear their ‘lucky’ coat in the operating theatre – a coat worn during a successful operation in the past. They do not wash their ‘lucky’ coat between operations in case this breaks their run of

Mickley‚ and Manuel T. Lerdau (2010) believe that the spread of Kudzu has the potential to raise ozone levels (this would be bad) by the emission of nitric oxide. Hickman and company created a study that observed the effect of kudzu on trace gas emissions in three different places in Georgia. Their study concluded that emissions of nitric oxide in the soils containing Kudzu were over 100% higher than the soil without Kudzu growing in it. According to the model created by Hickman et al. “Our model

How does the concept of chance relate to knowledge and knowing? When did something happen to you unexpectedly or by chance? A good number of things in everyday life might seem like a coincidence‚ or a lucky chance‚ also known as serendipity. Chance affects our everyday thinking. How much safer is it to travel by car than by bike? Should I drink another beer? Should I take a risk? We might claim we know something if it is very likely or highly probable. For example‚ in your study of science you

Substance abuse- Inhalants The term substance refers to chemical compound that are ingested in order to alter mood or behavior. Substance use: It is the ingestion of psycho active substance (which alters mood or behavior) in moderate amount that does not significantly interfere with social‚ educational or occupational functioning.

they are man made in factories. There are four main types of inhalants which are volatile solvents‚ gases‚ aerosols‚ and nitrites. Some examples of these are household products such as glue‚ paint thinner‚ and aerosol cans. Inhalants such as nitrous oxide (laughing gas) are used for medical purposes which put a person to sleep. Other than that there are no real medical uses for inhalants. Some ways Inhalants can be used are "sniffing" or "snorting" fumes from containers; spraying aerosols directly into
