Computational Fluid Dynamics Simulations
Fluid flows are encountered in our daily life as well as in engineering industries. Identifying the temporal and spatial distribution of fluid dynamic properties is essential in analyzing the processes related to flows. These properties, such as velocity, turbulence, temperature, pressure, and concentration, play important roles in mass transfer, heat transfer, reaction rate, and force analysis. However, obtaining the analytical solution of these fluid property distributions is technically difficult or impossible. With the technique of finite difference methods or finite element methods, attaining numerical solutions from the partial differential equations of mass, momentum, and energy have become achievable. Therefore, computational fluid dynamics (CFD) has emerged and been widely applied in various fields. This book collects the recent studies that have applied the CFD technique in analyzing several representative processes covering mechanical engineering, chemical engineering, environmental engineering, and thermal engineering.
Genetics And Periodontal Diseases
Periodontal disease includes a broad spectrum of inflammatory and destructive responses to oral microbes in the susceptible human host.The genetic disorders are not the cause of the disease, they are the amplifiers of the disease process. Evidence for genetic influence on periodontitis comes from multiple sources including familial aggregation and formal genetic studies of aggressive forms of periodontitis and twin studies of chronic periodontitis. Reports of genetic polymorphisms associated with periodontal disease are increasing,in this context, a brief review has been prepared to enlighten the readers about the various aspects of genetics which are being used in the field of Periodontics. The scenario of various case control studies and literature in the past to date in order to to provide a brief overview of basic genetic concepts, genetic polymorphisms and to discuss the genetic aspects of various forms of periodontal diseases

It presents the latest research work to provide insight into modern thermal engineering applications. It also discusses enhanced heat transfer and flow characteristics.
Early Pregnancy
A scientific and evidence-based guide to understanding early pregnancy development and clinical management.
Do Souls Exist?
The author experienced a freak encounter with the soul of his dead father. This soul stripping incident seemed so real that he could not dismiss it as false. However, he tried to erase the episode from his memory and failed so the impact of the unusual happening kept simmering at the back of his mind. He wanted to get rid from this suppressed mental condition but did not know, how mystical matters, which defy rational explanation are handled, consequently he posted a blog to invite readers to give their opinion on this extrasensory experience. Mario Beauregard, commented on this unexplainable explanation saying that … “Nobody but you can respond to your questions” … Likewise, Dr. Ray...
Control and Nonlinear Dynamics on Energy Conversion Systems
The ever-increasing need for higher efficiency, smaller size, and lower cost make the analysis, understanding, and design of energy conversion systems extremely important, interesting, and even imperative. One of the most neglected features in the study of such systems is the effect of the inherent nonlinearities on the stability of the system. Due to these nonlinearities, these devices may exhibit undesirable and complex dynamics, which are the focus of many researchers. Even though a lot of research has taken place in this area during the last 20 years, it is still an active research topic for mainstream power engineers. This research has demonstrated that these systems can become unstable...
