Respiratory papilloma changing to carcinoma in the absence of smoking and irradiation is seldom seen, with only about 20 documented cases presented in the literature. Here we report one such case in a 30-year-old male patient.

Much of the basin is arid, and runoff derives from the high elevation snow pack over the Rocky Mountains, which contributes about 70% of the annual runoff. A secondary source of water for the basin is the summer monsoon precipitation. The Colorado River system is one of the most heavily regulated for providing water supply, irrigation, flood control, and hydropower to a large area of the U.S. Southwest. Estimating intra- and inter-annual variability of water storage in the basin is important for sustainable water management. In this paper, an overview is given on how terrestrial water storage changes can be estimated. Fifty (50) years (1955-2005) of re-analysis data from ECMWF (European Center for Medium Range Weather Forecasts) is used together with observed and natural stream flow to derive monthly atmospheric and terrestrial water balances (Seneviratne et al., 2004; Hirschi et al., 2006). The resulting water storage changes in the Colorado basin exhibit a strong annual and a weaker decadal cycle. Correlation with different climate variability indices (ENSO, PDO, AMO) is examined. We compare these water storage change estimates with those derived from the NARR (North-American Regional Re-analysis) time series (1979 to 2005). Three years (2002-2005) of GRACE (Gravity Recovery and Climate Experiment) satellite data are then used to estimate monthly terrestrial water storage changes from estimates of geoid anomalies over the area. We find a close relationship between both independent estimation procedures. Both the annual cycle and the amplitude agree very well, although a slight phase shift of about a month is observed. To further examine the water storage changes we apply a land surface hydrologic model (VIC: Variable Infiltration Capacity) forced with observations spanning the period between 1950 and 2000 and compiled by Maurer et al. (2002).

We used lateral cephalographs of 31 patients taken before, immediately after, and at least one year after the operation. We recorded euclidean distance matrix analysis, linear and angular measurements, and x and y co-ordinates of cephalometric landmarks for each cephalograph. There were no significant differences in extent of the mandibular retrognathia or magnitude of change between the two groups. The main significant changes in both groups were reduction of the total mandibular length, and posterior shifting in the mandible. One year after the operation the main change was the mean forward relapse of 2.5 mm in the SSO group and the mean posterior relapse of 0.5 mm in the VSO group. The difference in skeletal stability between the groups was significant (P< 0.05), and we conclude that VSO is the more effective technique for correcting mandibular prognathism.

In the late 1990s, ICT brought in a unique concept—Electronic government (e-government)—in the field of public administration. Since then many far-reaching developments have been taken place in the field which tempt the governments of the world to start the ‘e-government journey’ in the hopes of experiencing efficiency, effectiveness and organizational performance. This paper examines the current status of ICT in Bangladesh by exploring the government initiatives, political commitment, as well as the enthusiasm of the private sector. The paper concludes that the e-government preparation of Bangladesh is still in the primary stage and has not obtained the expected outcomes due to some barriers (technical, infrastructural etc). At the end the paper viewed that may be the progress is slow and may be there is confusion about the means but there is no doubt a...
