Identification and validation of Outer membrane protein (OMP) P6 3D structure and its topology in Haemophilus influenzae
Haemophilus influenzae is a common human respiratory tract pathogen, causing disease in both children and adults. The bacterium is an important cause of otitis media, the most common reason for children to receive antibiotic therapy. Outer membrane protein P6 is a member of the class of outer membrane proteins known as peptidoglycan-associated lipoproteins. First discovered in the mid-1980s, P6 is a promising vaccine antigen that has been the subject of extensive study. P6 has several features suggesting that the protein may be an effective vaccine antigen. The gene that encodes P6 is present and the protein is expressed in all strains of H. influenzae examined thus far. The nucleotide sequence homology among strains is 97%, and the amino acid sequence homology among strains is 100%,…

In silico potential vaccine against hps06257 in Haemophilus parasuis serovar 5
Haemophilus parasuis is a small, pleomorphic, NAD-dependent member of the family Pasteurellaceae. This bacterium is the etiological agent of Glässer’s disease in swine, which is characterized by polyserositis and arthritis. Once a sporadic disease, it has increased in prevalence and severity in recent years with the adoption of new production technologies which has led to pigs being susceptible to this infection. However, a lack of protective cross-immunity against some strains and partial cross-protection among serotypes has been reported [4,5], pointing to the difficulty in identifying protective immunogens for a universal vaccine. Initial studies have already shown the importance of circulating antibodies in controlling H. parasuis infection. After experimental infection in…

Transient Stability Margin Assessment of a Power System Using Multi-Layered Perceptron Neural Network
Online transient stability assessment of a power system is not yetfeasible due to the intensive computation involved. Artificial neuralnetworks have been proposed as one of the approaches to this problembecause of its ability to quickly map nonlinear relationships between theinput data and the output. This paper presents a methodology forestimating the normalized transient stability margin by using themultilayered perceptron neural network. The complex relationshipbetween the input variables and output variables is established by usingthe neural networks. The nonlinear mapping relation between thenormalized transient stability margin and the operating conditions of thepower system is established by using the multi-layer perceptron neuralnetwork. To obtain the training set of the neural…

Fuzzy Sliding-Mode Controller Design for Two 4-D Different Hyperchaotic System
This paper presents a fuzzy sliding mode controller for synchronization of two 4-D hyperchaotic systems. This paper describes two 4-D hyperchaotic systems a LU system and a Newton-Leipnik system. A LU system is defined as master system and the Newton-Leipnik system is defined as the slave system. In the controller design, an additional controller is designed using a sliding surface to ensure the sliding motion through the entire state trajectory. The method of designing a fuzzy sliding mode control (FSMC) is provided, which utilizes a normalization factor. FSMC is designed to guarantee the global asymptotic synchronization of state trajectories of two different 4-D hyperchaotic systems. The effectiveness of the proposed FSMC scheme is verified by experimental results, and good transient…
Mathematical Modeling of Differential Equations of Concentration in a Sieve-Plate Extraction Column
In this study, the solute concentration in a Sieve-plate column was modeled. Two different models that were continuous phase axial dispersion model and disperse-continuous phase axial dispersion model were considered to simulate the behavior of the plate column under different flow rates. In fact, the solute concentration profiles in both disperse and continuous phase based on dispersion model with and without consideration of axial dispersion in both phase were studied. These models were validated by mass transfer tests with n-butanol/ acetic acid/ water system. According to results, the average deviation of 4.84% and 4.76% between experimental data and simulation outcomes in steady state condition were obtained for the models respectively, which showed a good agreement. Moreover, when…
Mathematical Modeling of Plug flow and Axial Dispersion Models in a Sieve-plate Extraction Column
Modeling of a counter-current Sieve-plate liquid–liquid extractor has been conducted using plug flow (PF) model and axial dispersion (AD) model. Several experiments were done using toluene/ acetic acid/ water system with acetic acid as mass transfer agent from aqueous to organic phase. New analytical solutions are proposed for two models respectively and the simulation results show a good agreement, compared with experimental data. In this paper, the solute concentration profiles in both disperse and continuous phases based on plug flow model as well as axial dispersion model and experimental values. The average deviation 12.47 and 7.26 percent between the experimental data and the simulation outcomes of the disperse and continuous phases composition in steady state condition were…
