Review ArticleOpen accessIn the keywordsExploring the Potential for Concentration of Nutrients from Urine Using Solar Evaporation and Carbon Dioxide Trapping of AmmoniaTesfamariam Y. Debessai, Ababu T. Tiruneh, Gabriel C. BwembyaNutrients derived from urine such as nitrogen, phosphorous and potassium constitute valuable sources of fertilizers needed for growing plants and as alternatives to commercial fertilizers. Concentration of nutrients available from urine provides advantages of reducing the volume of transportation, the health risk and making nutrient application to soil stable and suitable. An exploratory review of a possible technology for concentration … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 28 Oct 2019 · 7,167 accessesView PDFCite
Review ArticleOpen accessIn the keywordsStructure of Buried Ice on MarsRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuAfter the older evidence that there is carbon dioxide on Mars made up of oxygen 2 and carbon now we have evidence that there is even normal water on the marble consisting of hydrogen 2 and oxygen. In other words, we have Martian oxygen combined with carbon and hydrogen, so we can extract oxygen directly to the site to initially … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 7,212 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Basic Elements of Life'sRaffaella Aversa, Victoria Petrescu, Antonio Apicella, Ion Tiberiu PetrescuThe four basic elements of life are: Oxygen, hydrogen, nitrogen and phosphorus. These four elements are found in abundance in both the human body and in animals. There are other elements that compose the human body, but the four we've highlighted participate in all life processes. Besides, these four elements make up ATP chains (molecule), which governs and controls the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 17 Dec 2016 · 121,931 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Inclusion of Albizia saman Pods in the Diet on the Performances of Dairy CowsMin Aung, Yin Yin Kyawt, Moe Thida Htun et al.Ruminants can achieve high productivity when the diet includes concentrates; however these are often expensive due to competition with humans and mono-gastric animals. This experiment was conducted to determine the effect of partial inclusion of Albizia saman pods (ASP) in a Commercial Concentrate (CC) on the performances of dairy cows. Twelve cross-bred Holstein Friesian cows (472±13 kg) in the 12th … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 29 Dec 2015 · 7,585 accessesView PDFCite
