Double orifice mitral valve is a rare congenital heart disease. We present a case in which 3D echocardiography helped clarify the underlying anatomy. The need exists for more extensive use of this technique to allow for surgical and pathological confirmation.
Information and Communication Technologies (ICTs) in a relatively short period of time of our planet’s history have had a major transformative impact across all strata of society. In the study, four different villages (520 respondents) from four districts of Bangladesh have been selected to find out how ICTs played a catalytic role in dissemination of(More)
BACKGROUND Meningiomas are the most common intracranial tumor, but rarely, they can develop extracranially, usually in the neck. There are very few cases of parapharyngeal meningioma reported in literature and little is known about their biological behavior and operative management. We present a patient with a primary parapharyngeal meningioma that(More)
This paper aims to exploit technology in saving lives; a robotic arm is designed for EOD (Explosive Ordnance Disposal) applications that can rival the EOD robotic arms available in the market, in terms of both its capabilities and functionality, and still cost a small fraction of their price. Though there are many robotic arms that are commercially(More)
The primary objective of this paper is to analyze if the Market overvalued. We studied prices of 17 actively companies in the Market from 2006 to 2010 and used three Valuation Ratios with an explicit corporate sector along with overall market index data and found that the Stock Marke overvalued. The analysis was completed in two stages. At first we analyzed(More)
Nowadays, released of heavy metals from the industries to the water stream arises a severe environmental problem to human health and water ecosystem. The conventional wastewater treatment plant is no more effective in treatingthis contamination. Furthermore, the modern wastewater treatmentplantis expensive and inefficient. Therefore, in this paper studied(More)
A physical layer secret key generation scheme exploiting randomness of the road surface and the driving behavior is being proposed. 128bits encryption key is generated based on real world vehicle trajectory big-data to prove the concept. OCIS codes: (060.2605) Free-space optical communication; (060.4785) Optical security and encryption
Assessment of Evolvulus nummularius L. through whole plant extracts (collected in petroleum ether [Pet.E.], chloroform [CHCl3] and methanol [MeOH]) were made against Tribolium castaneum (Hbst.) for insecticidal and insect repellency and against Artemia salina L. for brine shrimp lethality, and the results were promising. The LC50 values against T. castaneum(More)
A novel physical layer secret key generation technique for point-to-point optical fiber link security is proposed. It can efficiently generate high entropy symmetric cryptographic keys based on Polarization Mode Dispersion in optical fiber links. OCIS codes: (060.2330) Fiber optics communications; (060.4785) Optical security and encryption;
