Research ArticleOpen accessIn the abstractZero Geometry, Zero Space Time, The Seeds of The Final TheoryKambiz-AfrasiabiProblem statement: Lack of understanding And scientific formulation of zero geometry and zero space-time and the truth about initiation conditions would continue to keep us all in dark and we would continue to create more theories defining our observations about the known universe which could Indeed be part of our illusionary perception of reality And as long as they continue … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Algorithmic Cost Estimation Model Based on Soft Computing TechniqueIman Attarzadeh, Siew Hock OwProblem statement: Software development effort estimation is the process of predicting the most realistic use of effort required for developing software based on some parameters. It has always characterized one of the biggest challenges in Computer Science for the last decades. Because time and cost estimate at the early stages of the software development are the most difficult to obtain … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,927 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutritional Value of the Maize Stalk Borer and American Bollworm as Unconventional Protein SourcesA.E. Ghaly, F.N. AlkoaikProblem statement: The maize stalk borer and American bollworm were grown in an artificial media to evaluate their potential as human food sources. Approach: Both cultures were started from moths and the life cycle and culture structures were evaluated. Results: The larvae of both insects reached maximum weight and maximum length at the same time. The growth rate of the … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Insects as Human Food in ZambiaA.E. GhalyProblem statement: The life cycle and culture structure of two commonly eaten worms in Zambia (Isoberlinia paniculata and Miombo/Mopani) were evaluated. The worms were grown on an artificial medium to evaluate the potential of producing them on a commercial scale. Approach: An interesting characteristic of the worms studied was that they reached their maximum weight and maximum length at the … …OnLine Journal of Biological Sciences, Vol. 9, Issue 4 · 31 Dec 2009 · 8,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetecting Hornbeam Trees Phenological Characteristics of Mountain ForestSasan Babaei Kafaki, Asadollah Mataji, Seyed Armin HashemiProblem statement: Phenology is the study of the seasonal occurrence of developmental or life cycle events, such as bud break, flowering, or autumn leaf drop. The proposed study attempted to quantify changes in Carpinus betulus L. phenology of deciduous broad leaf forest between the years 2003-2006.
