Electricity demand forecasting of an off-grid area, where no previous load data is available, is an important prerequisite for power system expansion planning. Bangladesh is a small as well as densely populated country in South Asia with a large portion of the population living under poverty line. About 48.5% of the total population has access in grid electricity. Uninterruptable power supply is one of the most important parameter for future development which ends up with a decision of obvious expansion of present grid coverage. This paper represents an analysis to forecast the electricity demand of an isolated island in Bangladesh where past history of electrical load demand is not available. The analysis is based on the identification of factors on which electrical load growth of an area depends. The forecasting has been done through inverse matrix calculation and linear regression analysis method. It has been found that the demand data, calculated from two different approaches, are close enough which spans the reliability of the proposed method. This method can be applicable for short term load forecasting of any isolated area throughout the world.

The aim of our study was to detect the prevalence of Legionella pneumophilia (L. pneumophilia) in DUWLS using standard culture technique (SCT) and the real-time polymerase chain reaction (PCR) method in order to assess the risk of L. pneumophilia contamination within a dental setting. A total of 65 water samples were collected from 16 dental units and one cold water supply system from all clinical departments. L. pneumophilia could not be detected in any of the water samples using the standard SCT (0%), whereas L. pneumophilia was detected using real time PCR in three (4.6%) water samples collected from the tap system. Following the detection of L. pneumophilia, the tap systems were disinfected with surface disinfectant and water samples were recollected. The recollected water samples following disinfection were negative for L. pneumophilia once analyzed using culture and real time PCR technique. Although the culture method using BCYE media is the ‘gold standard’ for the detection of L. pneumophilia; Real Time PCR analysis may also be a quick, useful, and sensitive method for the detection of L. pneumophilia in order to control and prevent possible infections that may arise in the dental setting.
