It is widely accepted that ambulatory care furnished in hospital outpatient department (OPD) settings is more costly than similar care furnished in office settings, but few researchers have explored whether practice patterns differ between the two settings. Differences in practice patterns may account for differences in the overall cost of care associated with these settings. Diagnosis-specific...

The aim of the study was to monitor non-steroidal anti-inflammatory drugs prescribing pattern for patients attending the dental OPD of Chitwan Medical College Teaching Hospital, Bharatpur, Nepal. 1173 prescriptions of patients attending the dental OPD were collected randomly during 15 July 2011 to 14 January 2012. Thedata was analyzed using WHO guidelines. The average number of drugs prescribed...

A visible light communication (VLC) system using an organic bulk heterojunction photodetector (OPD) is presented. The system has been successfully proven indoors with an audio signal. The emitter consists of three commercial high-power white LEDs connected in parallel. The receiver is based on an organic photodetector having as active layer a blend of poly(3-hexylthiophene) (P3HT) and phenyl C6...

One hundred patients were selected from the cardiology outpatient department by non-probability purposive method. Each patient was evaluated by a psychiatrist and a consultant cardiologist The informations were recorded in a self designed proforma. The Hindi version of Goldberg's General Health Questionnaire and modified adjective check list for type A and type B personality characteristics wer...

Objective: To study the pattern of aural morbidity among the paediatric population attending the ENT OPD of our hospital.

The growing interest for monitoring the quality of water has triggered the need of fast, portable and cheap detection systems. To answer this problematic, we developed a lab on a chip for herbicide detection based on micro algal photosynthesis. A blue organic light-emitting diode is used as the excitation source while the resulting algae luminescence is monitored using an organic photodiode (OP...

A novel method to double the measurement range of wavelength scanning interferometery (WSI) is described. In WSI the measured optical path difference (OPD) is affected by a sign ambiguity, that is, from an interference signal it is not possible to distinguish whether the OPD is positive or negative. The sign ambiguity can be resolved by measuring an interference signal in quadrature. A method t...

An analytical technique for extracting phase, visibility, and amplitude information as needed for interferometric astrometry for the Space Interferometry Mission (SIM) is presented. This model accounts for a number of physical and instrumental effects and is valid for the general case of a bandpass filter. I was able to obtain a general solution for polychromatic phasors and to address the prop...
