The security industry has developed for thirty years, which has becomes a part in people’s life. Information conveyed through relay technologies retains evidence of its discursive origins, of other information with which it has held company. To the extent that users are aware of those origins, they may be prompted to apply an associated interpretive frame. For instance, a technology that makes interactive tissue and cell slides helps users apply information that would normally require the mediation of a microscope in settings where no microscopes are available or where they would be impractical to use. The relay technology would allow the user to think like a microscope. For us time has been a very good teacher. People have realised so many things. We have learnt from the past – we have suffered alone. That pain and suffering has taught us a lot. We have begun to realise that we are not supposed to be living under these conditions. There has been a dawn of democracy for the poor. No one else would have told us – neither our elected leaders nor any officials would have told us what we are entitled to. Even the Freedom Charter is only good in theory. It has nothing to do with the ordinary lives of poor. It doesn’t help us. It is the thinking of the masses of the people that matters. We have noted that our country is rich. More airports are being built, there are more developments at the Point water front, more stadiums are being renovated, more money is floating around, even being lent to Mugabe. But when you ask for what is basic you are told that there is no money. It is clear that there is no money for the poor. The money is for the rich. We have come to the decision of saying ‘enough is enough.’ We all agree that something must be done. Poverty alleviation: It is known that a large part of the people involved in urban agriculture is the urban poor. In developing countries, the majority of urban agricultural production is for self-consumption, with surpluses being sold in the market. According to the FAO (Food and Agriculture Organization of the United Nations), urban poor consumers spend between 60 and 80 percent of their income on food, making them very vulnerable to higher food prices. The low-wing, quad-engine, aircraft, powered by Junkers Jumo engines and supported by massive floats, carried four crew members and 880 pounds of payload, and were cordite-launched from their ships’ 110-foot-long catapults, enabling them to accelerate from zero to 95 mph in just two seconds, a force equaling 4.5 g’s. A third airplane, the “Nordstern,” later joined the fleet, and seven round-trips were altogether made, on which the aircraft completed the remainder of the Atlantic crossing.

The actual and present condition of Africa is one of deep trouble, worse than the one imposed during the colonial times. Deserts have grown wider every year; the broad Savannas have lost their communities and have lost all their means of existence; tropical forest have disappeared through feeding the export maw; cities that do not deserve to called such, have spawned large scale poverty and plagues never seen, known or dreamed-of in human history; harsh and evil dictatorships who have ruled and are still ruling over people who distrust and hate them, and for a good reason; and in the case of Africa, one dismal tyranny gives was for another more worse one; despair rots civil society, and the state becomes an enemy, and bandits flourish. In 2005 shackdwellers and other marginalised people in Durban formed Abahlali baseMjondolo to protect the interests of the poor. I decided to stand strong with Abahlali. The movement became massive. It carried us like a powerful river. The days of my life became strenuous. Every time that Abahlali organised a protest, or I attended a conference or a workshop, or we were in the newspapers or on radio and TV, or even if I happened to have an article in a newspaper, my employer, the owner of the Petroport River Horse Valley, called me for a disciplinary hearing. At these hearings the charges were always made up and they always went away in the end. But what did not go away was that he would threaten me for speaking the truth about the life that the poor are living in this world. He told me clearly that he could not have me embarrassing the mayor. The second major classification of sensing device is chemical sensors. In this case sensors are concerned with the chemical quantities such as identifying the presence of chemical composite, detecting the concentration of various chemical species, and monitoring the chemical activities in the body for diagnostic and therapeutic application. A wide variety of chemical sensors are classified in many ways. Chemical sensors are used to detect chemical components being measured and chemical composition measured in the gas phase. Electrochemical sensors are utilized to measure chemical concentration, or more precisely, activities based on chemical reactions that interact with electrical systems. Photometric chemical sensors are optical devices that detect chemical concentrations based on changes in light transmission, reflection or color. Other types of physical chemical sensors such as the mass spectrometer utilize various physical methods to detect and quantify chemicals associated with biologic systems.
