In this era of globalization, the field entrepreneurship is seen as a major agenda in empowering and sustaining community’s economy. It has its role an economic catalyst capability empowered efforts to increase innovation, creativity, competitiveness society micro macro-economic perspectives. Awareness development shared values, well entrepreneurial activities, are also sown strengthened throug...

The ACIS front-illuminated CCDs onboard the Chandra X-ray Observatory were damaged in the extreme environment of the Earth's radiation belts, resulting in enhanced charge transfer inefficiency (CTI). This produces a row dependence in gain, event grade, and energy resolution. We model the CTI as a function of input photon energy, including the effects of de-trapping (charge trailing), shielding ...

The Chandra X-Ray Observatory observed the Crab Nebula and pulsar during orbital calibration. Zeroth-order images with the High-Energy Transmission Grating (HETG) readout by the Advanced CCD Imaging Spectrometer spectroscopy array (ACIS-S) show a striking richness of X-ray structure at a resolution comparable to that of the best ground-based visible-light observations. The HETG-ACIS-S images re...

Multi-fiber spectroscopy has been obtained for 335 galaxies in the field of the double cluster A3128/A3125, using the 2dF multi-fiber positioner on the Anglo-Australian Telescope. When combined with previously published results, a total of 532 objects in the double cluster now have known redshifts. We have also obtained a 20 ks Chandra ACIS-I image of the central 16 ́ x 16 ́ of A3128 and radio im...

We present the absolute measurement of the unresolved 0.5–8 keV cosmic X-ray background (CXB) in the Chandra Deep Fields (CDFs) North and South, the longest observations with Chandra (2 Ms and 1 Ms, respectively). We measure the unresolved CXB intensity by extracting spectra of the sky, removing all point and extended sources detected in the CDF. To model and subtract the instrumental backgroun...

Background: The use of anticholinergics has been on the rise. With increase in population longevity, more medication-related cognitive impairments (ACIs) have reported. These result significant morbidities. We present a case that stresses importance being vigilant when prescribing anticholinergic medications, especially elderlies. Case Report: A ACIs related to tiotropium bromide/olodaterol (St...
