The objective of this study was to investigate the growth rate of Chlorella vulgaris for CO2 biofixation and biomass production. Six mathematical growth models (Logistic, Gompertz, modified Gompertz, Baranyi, Morgan and Richards) were used to evaluate the biomass productivity in continuous processes and to predict the following parameters of cell growth: lag phase duration (λ), maximum specific...

A simple mathematical model for the temperature evolution in cornea exposed to short-pulsed Ho: YAG laser under Laser Thermo Keratoplasty (LTK) treatment is developed by incorporating heat flux phase-lag Fourier’s transfer and source term described Lambert Beer’s law. An analytical solution obtained using Laplace transformation technique. The computational results profile variation with time ar...

With the development and application of highway-speed nondestructive testing (NDT) devices, a reliable method to evaluate current level deterioration pavements from measured results is necessary provide comprehensive timely maintenance rehabilitation decisions for pavements. The objective this study conditions flexible their deflection profiles under moving loads. due primarily growth microcrac...

Responding to computer-initiated notifications requires a shift in attention and therefore disrupts the flow of work. Two exploratory experiments investigate how this decrement can be minimised when a short preparatory time is available before switching to deal with the interrupting task. The execution phase of a computer-based Tower of London task was interrupted by the requirement to perform ...

heat transfer phenomena in batch fluidized bed dryer have been studied and analyzed using three phase model including solid phase, interstitial gas phase and bubble phase based on rizzi model. new correlations of heat transfer coefficient to surrounding and convection heat transfer coefficient between solid and interstitial gas are being proposed. in addition, some modifications have been done ...

Ankle fractures are complex injuries with variable prognoses that depend upon many factors. The aim of the treatment is to restore the ankle joint biomechanical stability with maximum range of motion. Most ankle fractures are fibular fractures, which have a typical oblique fracture line in the distal fibula located in the area of the tibiofibular syndesmosis. The aim of this study was to simula...

The method used in maintaining cultures of Aerobacter m o g m s affects the relationship between duration of lag phase and age of inoculum in a gludose ammonium salt medium. Organisms kept in broth may show pronounced early lag whilst those from agar slopes do not. Previous subcultivation with aeration decreases the lag. Bacteria showing no lag may do so when they have been washed ; glutamate, ...

Boundary critical phenomena are studied in the 3State Potts model in 2 dimensions using conformal field theory, duality and renormalization group methods. A presumably complete set of boundary conditions is obtained using both fusion and orbifold methods. Besides the previously known free, fixed and mixed boundary conditions a new one is obtained. This illustrates the necessity of considering f...
