background: radiology staff needs to justify the radiation exposures in order to protect themselves and others from radiation risks. the aims of this study were to examine the awareness level of radiation dose and protection amongst radiographers and to compare their performance between major jordanian hospitals. materials and methods: a cross-sectional survey was conducted in 4 major jordanian...
The range of calibration of illuminance meters and luminance meters has been normally limited to levels up to several thousand lx and several thousand cd/m2 using a high-power luminous intensity standard lamp. The calibration of instruments at much higher levels is required in applications such as daylight measurement, evaluation of solar simulators, and testing light sources in imaging devices...
This research was conducted in March 2022 the waters of Talam Island, Central Tapanuli Regency, North Sumatra Province. study aims to determine relationship between coral cover and density megabenthos Island area. The method used this is a survey method. Coral data were collected using LIT (Line Intercept Transect) BBT (Benthos Belt Observations made at three station points with each depth 4 me...
Introduction: Radiography plays an important role in the diagnosis of oral and dental disease and one of the most common diagnostic procedures in dentistry. Recent reports have raised concern about the increased use of ionizing radiation in dental imaging and the possibility of cancers. The effective dose of some dental radiographic examinations is high enough, so appropriate ...
Introduction: Radiation exposure during radiological examination is a health concern, of which radiology professionals should be cognizant. We sought to evaluate the radiation protection knowledge, attitudes, and practice (KAP) amongst radiology staff of hospitals across 10 provinces of Iran. Materials and Methods: For evaluating the level of radiation protection KAP, 553 radiology staff were e...
[1] The United States Department of Agriculture UVB Monitoring and Research Program maintains a network of Yankee Environmental Systems surface UVB-1 meters distributed throughout the United States. We analyzed behavior of surface UVB radiation (280– 320 nm) over 8 to 10 years measured at eight stations within this network that were selected because of their early deployment (ranging from 1995 ...
Given increases in electricity consumptions, coupled with finite resources and technological advances, ICT-enabled electrical networks such as smart grids are increasingly being deployed by energy companies. One part of smart grids is smart meters, which are digital electrical meters, having the potential to increase energy efficiency in both residential and industrial sectors. However, a chall...
We estimate the effect of taxes on intergenerational transfers exploiting a sequence of Italian reforms culminating with the abolishment of transfer taxes. We use the 1993-2006 Survey of Household Income and Wealth, which has data on real estate transfers received and information on potential donors as well as recipients. Differencesin-differences estimates indicate that the abolition of transf...
