Research ArticleOpen accessAll words, across the recordCurrent and Future Nanotech Applications in the Oil IndustryCocuzza Matteo, Pirri Candido, Rocca Vera, Verga FrancescaProblem statement: Nanotech applications in the oil industry are not completely new: nanoparticles have been successfully used in drilling muds for the past 50 years. Only recently all the other key areas of the oil industry, such as exploration, primary and assisted production, monitoring, refining and distribution, are approaching nanotechnologies as the potential Philosopher's stone for facing critical issues related … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 10,624 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Automatic Topic Identification AlgorithmHossein Shahsavand Baghdadi, Bali Ranaivo-MalançonProblem statement: Topic is a stream of words which stands for the content of a text. Knowing the topic of a document can help people to be aware from its content and facilitate their searching process. Approach: This paper proposes an automatic algorithm to identify the topic for a textual document based on the chunks corresponding to each sentences in … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 6,906 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordRelation between Macroscopic Binding Constant and the Anticancer Efficacy of the Bovine Serum Albumin-Quercetin Complex against Drug-Sensitive and Drug-Resistant CellsWinit Choiprasert, Chatchanok Loetchutinat, Nathupakorn Dechsupa, Samlee MankhetkornProblem statement: We have previously analyzed the interaction of BSA with flavonoids by using FRET. In this study, the role of BSA on increasing in solubility and on carrying the quercetin derivatives thus enhanced their anticancer efficacy against drug-sensitive and drug-resistant cells were conducted. Approach: The macroscopic (KD) and microscopic (kd) binding constant of the complexation and the cellular partition … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 1 · 27 May 2011 · 8,292 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordUse of Optical Reflectometry to Observe Various Concentrations of GlucoseHariyadi SoetedjoProblem statement: Monitoring technique on glucose is a hot topic as this compound has been considered to be important in human healthties. Optical reflectometry has been used to study various concentrations of glucose dissolved in the water. Approach: The self-construction of reflectometer used was of hemi-cylinder aluminum to allow light beam strikes the sample at 70° for sor p-polarization state. … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,144 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordFactor Analysis, Target Factor Testing and Model Designing of Aromatic Solvent Effect of the Formyl Proton Nuclear Magnetic Resonance Chemical Shift in Para substituted BenzaldehydesGhazwan F. FadhilProblem statement: The variations of formyl proton Chemical Shifts (CS) of p-substituted benzaldehydes in aromatic solvents were investigated. The validity of several physical solvent and empirical solvent scales was examined. Also, to predict dipolarity-polarizability (π*) solvent scale for some aromatic solvents. Model designing was also achieved to rationalize the aromatic solvent effect on the formyl proton CS. Approach: The previously … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,582 accessesView PDF Cite
