In this study, a numerical computational fluid dynamics study is conducted in order to predict the aerodynamic forces on the NP car. The turbulent air flow around the car is modeled using the realizable k-ε model. First, results are validated against those presented for the Ahmed’s body. Next, the fluid flow around the car is simulated for different car speeds ( to mph) and fl...

For Diesel engines, the determination of the exit conditions of the injector nozzle flow is of great importance because it greatly influences the spray development inside the combustion chamber and hence the combustion process. In addition, it is relevant to know the flow conditions to provide the initial conditions for spray models. Since the possibility of experimentally observing and measuri...

COSMETIC surgery is not a new phenomenon. Facelifts, nose jobs, breast reduction and breast implants have been common among women for decades, and the profession and practice of cosmetic surgery is well established in many countries, including many developing countries. However, in the past 10–15 years, there has been a seismic shift in what is considered possible and desirable to change as reg...

Surgical approaches to the condylar fracture include intraoral, preauricular, submandibular, and retromandibular approaches. Each approach has its own advantages and disadvantages. When a patient needs esthetic results and an intraoral approach is not feasible, the transmasseteric antero-parotid facelift approach is considered. This approach permits direct exposure and allow the surgeon to fixa...

In the popular FOX TV reality show, American Idol, the judges, who are presumably experts in evaluating singing effort, have no voting power when the field is narrowed to the top 24 contestants. It is only the votes of viewers that count. In the 2007 season of the show, one of the judges, Simon Cowell, threatened to quit the show if a contestant, Sanjaya Malakar, who was clearly a low-ability c...

We investigate /xpoint operators for domain equations. It is routine to verify that if every endofunctor on a category has an initial algebra, then one can construct a /xpoint operator from the category of endofunctors to the category. That construction does not lift routinely to enriched categories, using the usual enriched notion of initiality of an endofunctor. We show that by embedding the ...

We evaluated the reliability of a translated Brazilian version of the Unified Huntington's Disease Rating Scale (UHDRS) to establish the reproducibility of the scale in a population that differs substantially from that on which the scale was originally validated. After a training period with the video and guidelines requested from the Huntington Study Group, we applied the UHDRS, except for the...
