  GERARD MERCADOGE-1213Articles about saving the environment:Print Green - ave Environment In this age of digital technology, printing presses still play a major role in the production of a range of materials such as booklets, posters, postcards, brochures, business cards, calendars, stationeries etc. While this wide-spread process of printing gives us such informative and eye pleasing products, the resultant environment pollution caused due to these goes unnoticed. Saving the environment is a responsibility that is vested on for all of us and thus the need of the hour is to print green.Printing green refers to the process that reduces wastes, encourages recycling and implements other measures that leads to an eco friendly printing operation. Such printing presses carry on their processes in a way that causes minimal harm to the environment. he primary concern for a green printing press is to manage wastes effectively. he objective is to have less waste being generated as that would mean fewer measures to be adopted to eliminate such wastes. Waste management starts from the prepress process itself. !fforts are concentrated towards pollution prevention processes that start with photographic chemistry management and recycling of used plates etc. urthermore the wastes are segregated into categories such as ha#ardous and non ha#ardous wastes. he discharge of ha#ardous wastes is carried out in an eco friendly manner. Waste management in green printing houses are two fold i.e. either they implement measures to reduce wastes or else recycle them. $igh volatile organic compounds are one of the prime causes of air pollution in the printing industry. hese compounds evaporate very %uickly at the room temperature which not only adds to more material consumption but also leads toair pollution. &reen printers use low '()*s in their printing processes thus reducing the air emissions and also less material consumption.&reen printers adopt various means to implement the current printing technologies that are eco-friendly. hus they not only help in reducing environmental pollution but improve the overall %uality of the product.  ave !rees - ave the Environment oday, when environment is being polluted so rigorously, everyone has only one %uestion on his + her lips and mind that is how to save environment from being polluted. $ow to protect earth from disaster he strongest way to protect environment is save trees. rees are one of the main creations of &od that play an important role to keep air clean. If there will be no fresh air available then how will human beings, animal, and birds survive herefore, a clean environmentis the need for every living object on this earth. any big organi#ations, schools, colleges, and &(s are taking initiatives to save trees for a better future, clean air, and unpolluted environment, in short healthy life for living objects.(ne of the biggest initiatives to save trees is taken by Idea )ellular /td. - a part of 0ditya 1irla &roup. oday, trees are being cut with a great speed for full filling daily needs of human beings. It is true that we need to cut trees for our daily needs but cutting trees in such a furious way is leading towards a disaster. 2ou might have noticed that as the number of trees is reducing3 disasters are being continuously increasing, which is ultimately leading into high death rate. 0 big part of the trees is cut to make paper to help us do our personal and official works. If the use of paper will be minimi#ed then we can save a large number of trees from being cut, which leads into healthy and clean environment that is fresh air and healthy life.Initiative taken by Idea )ellular /td. is really appreciable. With their ads, they are promoting the use of paper less media like mobile phones. It is really a greatidea to use paperless media to minimi#e the use of paper. 0nother initiative, which has been taken by schools, colleges, and universities in the increase in online e4aminations. 1eing a responsible human being, we all need to take some initiatives to protect environment. We can consider following ways to save trees, to protect environment, and to live a healthy life5 ã Plant as much trees as possible. ã 6o not cut trees until there is an e4treme need. ã Prefer paperless communication instead of using paper. ake use of Internet and mobile phones to promote paperless communication. ã (nline e4amination system should be preferred instead of taking e4ams on paper. ã inimi#e the use of paper towel. In place of paper towel, one can use cloth towel or hankiehese are few ways to build healthy environment, to save earth, and to live a healthy and diseases free life.  Articles about engineering an science:#o$ Does %our Green Roo& Gar en Gro$' &rowing plants on rooftops is an old concept that has evolved from simple sod roofing to roof gardens and new, lightweight 7e4tensive green roofs.7 odern green roofs have environmental and social benefits3 they can reduce stormwaterrunoff, improve air %uality, mitigate urban heat, reduce the demand for air conditioning and greenhouse gas emissions, and provide habitat for birds and wildlife. /ong-used in urban planning in !urope, green roofs are becoming more popular in orth 0merica, and new research designed to promote the integration of green roofs into current and future buildings is burgeoning.8esearchers from the 6epartment of $orticulture at he Pennsylvania State 9niversity published a study in $ortechnology   that evaluated the influence of substrate type and depth on establishment of five common green roof plants.Plants suitable for e4tensive green roofs must tolerate e4treme rooftop conditions, and the substrates in which they grow must meet both horticultural and structural re%uirements. 6eeper substrates may retain more water for plants during dry periods, but they also weigh more, especially when near saturation. he study by )hristine !. huring, 8obert 6. 1erghage, and 6avid :. 1eattie was designed to evaluate the effects of substrate type and depth on the establishment and early growth of five plants popular in orth 0merican green roof designs.he researchers hypothesi#ed that early drought is more harmful for plants grown in shallow rather than deeper substrate depths, and that plants that survived early drought conditions would produce less shoot biomass than those subjected to late drought. wo stonecrops, one ice plant, and two herbaceous perennials were planted in three depths ;<=, >=, and ?@= mmA of e4panded shaleand e4panded clay, two commercially available green roof substrates. Study flats inside a plasticulture tunnel received three drought treatments5 no drought, @ weeks early drought, and @ weeks late drought.he two stonecrops performed well under most conditions, although tasteless stonecrop was stunted by early drought. Ice plant performed erratically and, along with maiden pink, poorly in face of drought during establishment. When subjected to any drought, the herbaceous perennials had the fewest survivors in the e4panded shale. he study plants were most affected by substrate depth, e4cept for maiden pink, which responded solely to drought. When subjected to early drought conditions, the herbaceous perennials did not survivein <= mm of either substrate, or in >= mm of e4panded shale3 early drought  appeared to be more harmful to plant survival and performance than late drought. 0lthough the stonecrops performed well in >= mm of substrate when subjected to drought, their performance was superior in the e4panded clay compared with shale.he three most resilient species used in the study -- sa4ifrage pink, white stonecrop, and tasteless stonecrop -- always produced more shoot biomass with increasing substrate depth, regardless of water availability. 0 standout performer was sa4ifrage pink, which had an attractive appearance and persistent flowering habit, making it an e4cellent choice as a green roof plant.he e4periment illustrates how appropriate species selection in the design of unirrigated e4tensive green roofs may be directed by factors such as substratetype and depth, as well as anticipated drought conditions. 7his e4periment revealed the variability among drought-tolerant species to various treatments, as well as the different plant responses to substrate type during drought,7 concluded the scientists. Antimatter he worldBs largest scientific research facility CSwit#erlandBs )onseil !uropDen pour la 8echerche uclDaire ;)!8A - recently succeeded in producing the first particles of antimatter. 0ntimatter is identical to physical matEter e4cept that it is composed of particles whose electric charges are opposite to those found in normal matter. 0ntimatter is the most powerful energy source known to man.
