Research ArticleOpen accessEvery word in the titleInvestigation of the Dimensions Design Components for the Rectangular Indirect Resistance Electrical FurnacesSalah K. JawadProblem statement: The objective of this study was to study the Indirect Resistance Electrical Furnaces (IREF) based on analytical and experimental analyses. The analytical analysis focused on a constant set of equations representing the internal and external flow of heat energy in the furnace, which demonstrated, relatively with the surface area of walls, heat transferring inside the furnace chamber to … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,438 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEssential Oil Component in Flower of Lemon Balm (Melissa officinalis L.)Jafer Adinee, Khosro Piri, Omid KaramiThis research focuses on the analysis of the chemical composition lemon balm essential oil. The essential oil of flowers was obtained by steam distillation with a Clevenger apparatus. The chemical components of the essential oil of lemon balm were analyzed by capillary GC and GC/MS and 12 substances were identified. The flower oil contained trans-carveol (28.89%), citronellol (25.24%), δ-3-carene (5.26%), … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,122 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInoculation of a Poultry Isolate Salmonella enteritidis on Egg Vitelline Membrane: Survival and Growth in Egg Components after Different Refrigeration Storage TimesZ.R. Howard, R.W. Moore, I.B. Zabala Diaz et al.An in vitro study was designed to determine the extent of Salmonella enterica serovar enteritidis survival and growth permissiveness in egg components isolated from shell eggs held at refrigeration temperature over an 8 week time period. Eggs were collected from a commercial laying facility at one-week intervals for eight weeks and stored at refrigeration temperature. After storage, eggs were dipped … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 7,664 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effects of Harmonic Components on Transformer Losses of Sinusoidal Source Supplying Non-Linear LoadsI. Daut, H. S. Syafruddin, Rosnazri Ali et al.An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Transformers are major components in power systems. The increased losses due to harmonic distortion can cause excessive losses and hence abnormal temperature rise. The measurement of iron losses and copper losses of single-phase transformers is important in particular for transformers feeding nonlinear … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 8,401 accessesView PDFCite
