Post Tender Negotiation (PTN) procedure is part of the tendering process in procurement goods and services. The could be triggered if initial activity does not result selection a supplier. This due to lack clear Value for Money (VfM) bidder. PTN sparingly applied UK public sector reasons adduced this are based on ethical considerations. Office Government Procurement (OGP), formerly known as Com...

BACKGROUND Along with the rapid growth of technology its related tools such as computer, monitors and video display terminals (VDTs) grow as well. Based on the studies, the most common complaint reported is of the VDT users. METHODS This study attempts to design a proper tool to assess the visual fatigue of the VDT users. First draft of the questionnaire was prepared after a thorough study on...

The cortical hierarchy of the human visual system has been shown to be organized around retinal spatial coordinates throughout much of low- and mid-level visual processing. These regions contain visual field maps (VFMs) that each follows the organization of the retina, with neighboring aspects of the visual field processed in neighboring cortical locations. On a larger, macrostructural scale, g...

During a cardiac cycle, the filling and emptying of the left ventricle (LV) are associated with characteristic patterns of blood flow motion. Diastolic filling shows an initial rapidly flowing transmitral jet, which decelerates and is subsequently redirected towards the LV outflow track. During this process of flow redirection, the formation of vortices store part of the kinetic energy of the i...

The formation of vortex rings during the left ventricle (LV) filling is an optimized mechanism for blood transport, and vorticity important measure a healthy heart LV. There relationship between abnormal diastolic structure impaired LV, hence identification vital understanding underlying physical flow. However, due to lack quantitative methods, defining, computing mapping ventricular vortices h...

Monitoring spatio-temporal changes of aerosols is necessary to better understand atmospheric processes. Here, the vertical distribution and how it has changed from 2006 2017 studied using time series data Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) instrument on board Infrared Pathfinder Satellite Observation (CALIPSO) satellite. Aerosol centroid altitude, a variable representing ...
