Research ArticleOpen accessIn the abstractSomething about the Mechanical Moment of InertiaFlorian Ion T. Petrescu, Antonio Apicella, Aversa Raffaella et al.In this study, the relations to determining mass moments of inertia (mechanical) for different mass and mechanical inertia corresponding to geometric shapes, objects and profiles are explored. The formulas for calculating the mass moments of inertia (mechanical) for various bodies (various geometrical forms), to certain major axis indicated (as the axis of calculation) are presented. The total mass M of … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 4 Nov 2016 · 11,376 accessesView PDFCite

The importance of the field of receptor research is supported by the large number of articles published in journals, the numerous specialty journals, the international conferences and the percentage of legal drugs on the market … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 8 Dec 2015 · 8,056 accessesView PDFCite
Research ArticleOpen accessIn the abstractMachine Motion Equations at the Internal Combustion Heat EnginesFlorian Ion T. PetrescuThis paper presents an algorithm for setting the dynamic parameters of the classic main mechanism of the internal combustion engines. One presents the dynamic, original, machine motion equations. The equation of motion of the machine that generates angular speed of the shaft (which varies with position and rotation speed) is deduced by conservation kinetic energy of the machine. An additional … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 21 Apr 2015 · 9,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractTESTING CARBOXYMETHYL CELLULASE ACTIVITY SECRETED BY TRICHOPHYTON TERRESTRE IN CARBOXYMETHYL CELLULOSE SOLUTIONMansoor Ahmad Lone, Sanjay Sahay, Ravinder, DeepakThe techniques employed for bioconversion of cellulosic biomass to simple sugars by cellulases have a great industrial brunt. Cold-adapted microorganisms are potential resource of cold-active carboxymethyl cellulases secluded from the cold regions. In this study, Trichophyton terrestre-a rare fungal species in Indian soils, isolated from the rhizosphere of Juglans regia L. during winter season was subjugated for the production and … …Current Research in Microbiology, Vol. 5, Issue 1 · 4 Feb 2015 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Shocks in Vibrationally Nonequilibrium Diatomic Gases at Various Distances from Critical Cross-Section of NozzleRydalevskaya Maria Alexandrovna, Voroshilova Yulia Nikolaevna, Uskov Vladimir NikolaevichThe high-temperature diatomic gas flows are considered in expanding nozzles under the conditions of a disturbance of the equilibrium distribution over vibrational levels of the molecules. The investigation of such flows is bound up with the problem of the inversion of the vibrational populations in the active mediums of molecular lasers. Under diverse values of the pressure overfall on coming … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractMICROWAVE-ASSISTED EXTRACTION OF PHENOLIC ANTIOXIDANTS FROM SEMIARID PLANTSJorge E. Wong-Paz, Juan C. Contreras-Esquivel, Diana Muñiz-Marquez et al.Microwave-Assisted Extraction (MAE) kinetic in three temperatures was investigated for extraction of antioxidant phenolic compounds from Jatropha dioica, Flourensia cernua, Eucalyptus camaldulensis and Turnera diffusa which are plants of semiarid regions of Mexico. The two-site kinetic model and saturation simple equation were used to describe the experimental data. The fit of the data demonstrated that saturation simple equation was better … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 22 Mar 2014 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Mathematical Modelling of Reaction Kinetics for Cyclodextrins Production from Different Starch Sources Using Bacillus macerans Cyclodextrin GlucanotransferaseSyahinaz Shahrazi, Suryani Saallah, Mohd Noriznan Mokhtar et al.This study relates to the mathematical modelling of enzymatic production of Cyclodextrins (CDs) by Cyclodextrin Glucanotransferase (CGTase) from Bacillus macerans. The experiments were carried out in batch mode using different starch sources and the results were used to estimate unknown parameters using linearization and dynamic simulation methods. α- and β-CD produced from tapioca were found to give the highest Michaelis-Menten … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 7,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Thermodynamic and Kinetic Parameters Determination Using Differential Scanning CalorimetryNader Frikha, Mohamed Bouroukba, Eric Schaer, Jean-Leon HouzelotProblem statement: The determination of reaction kinetics is of major importance, as for industrial reactors optimization as for environmental reasons or energy limitations. Although calorimetry is often used for the determination of thermodynamic parameters alone, the question that arises is: how can we apply the Differential Scanning Calorimetry for the determination of kinetic parameters. The objective of this study consists … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 7,986 accessesView PDFCite
