These fuels draw on lots of resources that will eventually diminish, making them too expensive or environmentally damaging to recover. Wastes are convertible to useful energy forms like polluted air or even sound waves. This research's primary investigation is to present using the sound waves that come out from the factories' machines' and converting it to electricity. The produced electricity will return to the machine and operate it without using an external source of electricity. The experiment was done using a power amplifier, capacitors, electric condenser microphone, potentiometer, and ohms. The experiment results fulfilled the design requirements as cost reduction, high efficiency and quality, and long endurance. The prototype output of electricity was 16V, and its efficiency was 15%.

Most of the weight of your hydrated brain comes from fats called "lipids". The brain also contains proteins, amino acids, micronutrients, and glucose. It takes these proteins from your food. However, that post-lunch apathy or late night alertness you might be feeling could simply be the effect of your food eating habits on your brain. The superstar fats are omegas 3 and 6. They have been linked to the prevention of degenerative brain conditions caused by our diets. Eating food rich in omega like nuts, seeds, and fish is crucial to the creation and maintenance of cell membranes. In contrast, long term consumption of other fats like food high in animal fat or sugar can affect your health in a bad way. Eating these types of fats can cause diseases, such as obesity and type 2 diabetes. The people diagnosed with these diseases are more likely to develop memory loss and even dementia or Alzheimer's disease. It was experimented that the neuron's rat which ate high fat and sugar diet had shorter and thinner dendrites, therefore, has a little number of synapses-dendrites transmit signals and synapses are the actual sites of neuronal communication-this could be one of the reasons that cause dementia. It also produces inflammation in the hippocampus, because astrocytes and microglia-two types of glial cells-support cells in the brain and become activated to protect neurons from inflammation become activated in response to the harmful environment. The brain needs more energy than other cells. Glucose is the only fuel that can be used directly by the brain. Neurons are always in a state of metabolic activity and have constant demand for energy, even during sleep. Because neurons cannot store glucose, they depend on the bloodstream to deliver a constant supply.

The presence of plastics in water, is one of the most hazardous types of water pollution. Plastic is used daily in our life and usually ends up in
the water. After plastic is dumped in water, it turns into microplastics. These microplastics are harmful to the whole ecosystem as many microorganisms feed on them. The purpose of the paper is to address some prior solutions for the problem of presence of microplastic in water and modify their disadvantages. The experiment was constructed by putting the reducer at the top to increase the velocity of the water, then the pipes will be connected by the 90Âșelbow to reverse the direction of the water, and finally the pipes that are in the same direction will be connected by a coupling. The water will pass also by the sponge which was put between the first elbow and coupling and the second
elbow and coupling. After doing the experiment and letting the water
pass through the filter, a huge quantity of microplastics were prevented. The design requirements were accomplished as the
efficiency was nearly equal to 98.75%, The solution does not affect the water chemical and physical properties as the pH of the water was
equal to 6.96. The flow rate has a value of 250L/h, after filtration. The prototype would be a suitable solution for the large scale consumption.

Therefore, air pollution has become a growing concern of new civilized world. It is considered as the major environmental risk factor in the incidence and progression of some diseases. Evidence suggesting that persistent environmental pollutants is due to the globalization of industrial production and to the energy needs. Several reports have revealed the direct relation between exposure to the poor air quality and increasing rate of morbidity and mortality. The main investigate of this research is to present the issue of air pollution and discuss the latest solutions findings of fundamental research with regard to its consequences on human health. This paper assists whether these findings are effective and ready to be applied in real life application or not. This research integrates some prior solutions for the industries that emit a large amount of hazardous pollutants either by using some catalysts like zeolite or techniques like the oxygen-enriched combustion to decrease the adverse emissions or using filters like the activated carbon air filter to filter the air from pollutants and between ways to decrease the spreading of the endangerment gases. The results of these findings indicate that these solutions are valid to be applied and fully prepared to take capitalize from. If some of these solutions are implemented on the large scale, the balance between the industrial revolution and the environment would be maintained and enhanced. The review ends with identifying gaps and limitations in some solutions about air pollution, and recommended some ways for the world to solve it with some development research needed in the subject area.

Human populations are using oceans as their household dustbins and microplastic is one of the components which are not only polluting shorelines, but also fresh water bodies globally. The purpose of this paper is to address an efficient and affordable solution to increase sources of clean water by filtering the polluted water from microplastic. It also unites prior researches that formerly succeeded to solve the problem. The paper investigates the extraction of microplastics from oceans by using a chemical method. It depends on the chemistry concept "like dissolves like." The experiment was made with simple materials and achieved great results. The results showed that the experiment fulfilled the design requirements of the High Efficiency, pH, Applicability, and Eco-friendly. The results of the experiment indicate that it is valid to be applied and fully prepare to take capitalize from.
