This paper explains the project which is a special kind of circular rotating 8 LED display. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to very affordable price and power is also saved. Also, maintenance and repairing of the display is so easy, that anyone having a little electronics knowledge can take care of this. All the synchronizin...

The development of the digital computer and its usage day by day is rapidly increasing. But the reliability of electronic components is getting affected critically by the temperature at which the junction operates. As operating power and speed increases, and as the designers are forced to reduce overall systems dimensions, the problems of extracting heat and controlling temperature becomes cruc...

Fins are protrusions on a heat transfer surface to augment heat transfer rate from it. The increase in area exposed to convection in case of finned surfaces results in increased heat transfer rate. In this study heat transfer characteristics of a pin fin with perforation is numerically analyzed. A pin fin is fabricated and experiments are done under forced convection conditions. The experimenta...

INTRODUCTION Over-expression of penile neuronal nitric oxide synthase (PnNOS) from a plasmid ameliorates aging-related erectile dysfunction (ED), whereas over-expression of the protein inhibitor of NOS (PIN), that binds to nNOS, increases ED. AIM To improve this form of gene therapy for ED by comparing the electrical field response of short hairpin RNA (shRNA) for PIN with that of antisense P...

The Stirling engine is an externally heat closed loop with a high theoretical performance and low emissions compared to other conventional engines. This property nowadays becomes very advantageous due its multi-fuel capacity including solar, biogas geothermal energy. In this study, numerical investigation of the effect circular, pin, rectangular fins on introduced. 3D CFD model was performed va...

o bjective: to describe the clinical characteristics, presentation and management of pardah pin inhalation in female teenagers of single center in northern india. m e thods: this was a prospective cross-sectional study being performed in department of cardiovascular and thoracic surgery of sher-i-kashmir institute of medical sciences located in northern india from january 2009 to december 2012....

We present a pin-assignment algorithm based on a new multi-layer chip-level global router. Combining pin assignment and global routing has been an important approach for the pin-assignment problem. But there are many difficulties when combining the two processes. In the past, only specialized global routing methods were used in the combined process. In our pin assignment program, we use an actu...

probability of private information based trade (pin) has introduced as information risk measure. this paper is going to estimate probability of private information based trade (pin) in tehran stock exchange using microstructure models. our results show that pin is significantly different from zero for tehran stock exchange.

INTRODUCTION Pediatric supracondylar humerus fractures are the most common elbow fractures in pediatric patients. Surgical fixation using pins is the primary treatment for displaced fractures. Pin site infections may follow supracondylar humerus fracture fixation; the previously reported incidence rate in the literature is 2.34%, but there is significant variability in reported incidence rates ...

UNLABELLED Pin tract inflammation and/or infection are common with the use of external fixation devices. Pin sites need to be managed to help prevent complications. There are a variety of regimens proposed for pin care in the literature. The authors present an efficient and simplified approach for addressing pin care protocol using cord locks with the use of compression sponges for external fix...
