The mean and conditional temperature and velocity profiles and their correlations were measured in a heated jet of air. The conditional measurements were “zone” averaged measurements, taken only in the fully turbulent region of the flow field by using an electronic sampling technique. The zone averaged measurements were taken of the velocity, temperature, shear stress, and the velocity-temperature correlation at three axial stations: x/D = 35, 45, and 50. The jet Reynolds number (based on the jet slot width) was held constant at 1.43 × 104, with a jet exit temperature excess of θ = 35°C. The conditioned profiles show a large variation from the mean measurements in the fully turbulent region of the jet. The zone averaged measurements approach the mean only as the jet center line and jet interface is approached.

OBJECTIVES: The objective of this study was to compare working length calculated with conventional radiographs and an electronic apex locator (IPEX II) during the root canal treatment of mandibular anterior teeth. METHODOLOGY: A cross-sectional study was done in the Department of Operative Dentistry, Sardar Begum Dental Hospital, Peshawar during February and March 2018. A consecutive sampling technique was used for sampling. Only 30 patients fulfilled the inclusion criteria of our study. Detailed medical and dental history was taken. Only patient fulfilling inclusion criteria were enrolled in the study. Data were analyzed using SPSS version 20. RESULTS: The mean age for patients was 45.33±5.16. 33% out of 30 patients (10) were male and 20 were females. The mean working length calculated from radiographs was 22.25±1.29 (min 20.09-max 24.10). The mean working length calculated by the electronic apex locator (IPEX II) was 22.17±1.28 (min 20.00-max 24.07). The mean difference between working length calculated by radiograph and electronic apex locator was -0.084mm, which means the working length determined by radiographs and by electronic apex locator has no difference in mandibular anterior teeth with single canals. CONCLUSION: Both the methods can be used effectively in endodontics for single-rooted mandibular teeth, but if both are used in combinations can lead to an improvement in the working length accuracy, which may significantly reduce the number of radiographs exposure, and increase the success and comfort for endodontic patients. KEYWORDS: Working Length, Apex Locator, Conventional Radiograph

Abstract This work summarizes efforts to determine the accuracy and performance characteristics of a new and novel laser diagnostic to measure instantaneous, in flight, droplet temperatures. The instrument uses the location of the rainbow peak to deduce the refractive index of the droplet, which in turn is related to the droplet temperature. Preliminary experiments were undertaken in order to understand the fundamental operating principles and limitations of the instrument. These experiments measured the temperature of an isothermal, single stream of monodisperse droplets. These measurements indicate that the mean refractive index can be measured with a standard deviation as low as 0.0001m. Once the operation of the refractometer was proved under isothermal conditions, the measurement of droplet temperatures in a swirl-stabilized combustor was performed. These measurements indicate that the strength of the rainbow signal is significantly hampered by the noise induced by the flame. Preliminary temperature measurements with the combustor equipped with 45° vanes showed relatively constant radial temperature profiles (∼55–60°C) at locations less than 2 inches from the nozzle exit. A detailed examination of the temperature correlation with velocity and diameter revealed that larger and faster moving droplets dominate the distributions. Thus, the smaller droplets that are suspected of having the highest temperatures are inadequately represented in the mean droplet temperature.

The purpose of this study was to determine the factors that affect the quality of life of CRF patients in Hemodialysis Unit at Pringsewu District General Hospital. This study was conducted from February to May 2018 with cross sectional study design. The sampling technique using total sampling technique. Measurement of quality of life using KDQOL-SFTM version 1.3. The results found that quality of life scores were quite low in some domains and subscales. The mean of total score was 55.70 ± 21.30 with mean of Physical Health Composite (PHC) = 38.85 ± 9.26 and mean of Mental Health Composite (MHC) = 36.13 ± 7.08. Regarding the targeted area of ESRD, the scale of renal disease burden and occupational status scale resulted in the lowest score. The sleep quality scale score was 56.18 ± 20.72. Only 61 patients responded to questions of sexual activity with a score of 55.53 ± 27.44 on the scale of sexual function. In the 36-item health survey, the mean total score was 45.90 ± 21.95. The lowest score represented the limitations of roles caused by physical and emotional health problems. The result of statistical test showed that the variables significantly related to the quality of life of CRF patients were age, income, duration of hemodialysis and family support. Thus, family support was the variable that had the greatest impact on determining the quality of life of CRF patients. The CRF patients who lacked family support were 4.6 times more likely to lead poorer life compared to CRF patients who received good family support after being controlled by age, income, duration of hemodialysis, gender, working status, and diabetes mellitus variables.
