Today is the 10th annual World Toilet Day. Sponsored by the Singapore-based World Toilet Organization, the event is meant to build awareness about the risks that lack of sanitation present to the physical, emotional and psychological health of 2.6 billion people around the world. Fortunately, poor sanitation is receiving an increasing amount of attention from NGOs, academics and other problem-solvers around the world. But there isn’t time to waste, since lack of hygiene contributes to diarrheal diseases that claim the lives of 1.5 million poor children each year.
Earlier this year, The Gates Foundation awarded a total of $3 million to researchers at 8 universities as part of its Reinvent the Toilet competition. Unlike the innovations that are taking place with flush toilets, these grants are aimed at designing, developing and prototyping waterless, hygienic toilets that cost less than $0.05 per user per day. The foundation also awarded a $4.8 million grant to the London School of Hygiene and Tropical Medicine (LSHTM) for a project called Sanitation Ventures. For it, researchers are developing ways to speed up the decomposition process in pit latrines. Organisms such as tiger worms, placed near the surface of the latrines, can effectively increase the speed of composting. Beneath that, in a filtration bed, liquid waste is further treated by aerobic bacteria. The end product is a treated sewage material that can later be used as a fertilizer.
And if that sounds gross, well, get over it. Human-waste-based fertilizer has been used in many parts of the world for centuries. The key is to process it correctly — at the right temperature and for enough time — to ensure that all pathogens are eliminated. In fact, aside from better public health, one of the major benefits of developing sanitation solutions for the developing world is creating an end product with value, such as fertilizer or biochar for energy.

According to the text, poor sanitation
A logic circuit has three boolean inputs and one output named A, B, C and S respectively. The boolean input A is connected to an inverter gate, and its result is submitted to an AND gate, along with the input signal B. The AND gate output is then submitted to an OR gate along with the remaining boolean input C. The output of the OR gate is the resulting signal S.
De acordo com o texto, o circuito lógico possuiA 4 poles pairs synchronous machine operates as a motor inside an industrial electrical network, with nominal frequency of 50,0 [Hz]. The synchronous machine rotor is equipped with short-circuited bars, creating a squirrel-cage auxiliary winding, dedicated for dumping effects during transients and also to allow the startup of the motor, when the machine is directly connected to the mains power source.
É apresentada no texto uma máquina elétricaA transformer has a primary winding circuit with 200 turns and a secondary winding circuit with 10 turns. In an ideal, lossless, transformer model, the magnetic core permeability is infinite despite the voltages applied to the windings, the two windings are perfectly coupled and there are no internal resistance in the condutors. In such transformer, when a sinusoidal voltage is applied at the secondary winding with an amplitude of 5,0 [V] RMS, the RMS voltage in the primary winding terminals is equal to 100,0 [V].
Com relação a esse texto, assinale a alternative correta.In an experiment, two point charges Q1 and Q2 were put on a straight line path, at a certain distance from each other. When both Q1 and Q2 are charged with +2,0 [mC] each, the resulting electric field intensity equals zero in the middle point in the line path between Q1 and Q2. This is true since their electric field vectors in this position have the same magnitude but opposite directions.
