This study assessed the production and price instability of pulses in Bangladesh. The study analyzed the data in different ways to capture the different views of instability by the different participants. Grass pea was constituted highest seasonal price instability among the all viewers and pigeon pea was in the lowest ranking. Average model, random walk model, linear trend model, exponential trend model and ARIMA model were applied to determine the production and long run price instability. Average viewers had a feeling of more instability than others for both the cases. ARIMA type models...

In the case of computed tomography (CT) scan, the measurement of effective dose is very essential. A patient size-dependent factor will be used to estimate patient dose from scanner output indices (e.g. Computed tomography dose index, CTDIvol) for patients of different sizes. The size dependent factor shall be used over a range of patient sizes, and extends to large patients as well as small patients.This research performed the estimation of effective dose during CT scan of brain of patients by using PMMA 32 cm reference phantom for treatment planning. The effective dose has been calculated...

Over the last 50 years, temperature capability of Ni-based superalloys has been improved as a means to improving thermal efficiencies in aeroengines and power stations. Creep strength is the most important property for gas turbine as the rafted structure is collapsed in the later stage causing unexpected deterioration of strength. Diffusion of elements is important for understanding the high temperature processes including homogenization and precipitation of the phases. Alloys with the Re/Al ratio up to 0.1 shows satisfactory oxidation resistance but that greater than 0.1 exhibits poor...
