Melanoma Extracted from the Common Bile Duct

A 54-year old woman presented to hospital with two days of epigastric pain, nausea and vomiting. Her history was significant for malignant melanoma of the right leg, diagnosed five years earlier, with subsequent endometrial, breast, lung and cerebral metastases. Liver enzyme levels were elevated (aspartate aminotransferase 230 IU/L, alanine aminotransferase 336 IU/L), with a total bilirubin level of 178 μmol/L. Computed tomography scanning demonstrated biliary dilation and a distal common bile duct (CBD) mass

Trends analysis of Vehicle Collisions using Hadoop and Spark

Vehicle collisions ranks amongst the main reasons for increased fatalities since few years. Vehicle collisions are the leading reason for fatalities and injuries in the age group below 24 age. The number of lives taken by vehicle collision in 20th century was equivalent to the number of fatalities in World War II. Therefore, necessary actions are required to be taken to bring down the number of collision incidents. The trends in vehicle collision incidents focuses on analyzing the changes in collision incident patterns over past few years. The main intention of this project is to find the pattern of incidents happening daily with respect to time, day, location and reason. If the trends are analyzed, the prediction of similar incidents can be confirmed and precautionary actions can be taken

Climatic response of various tree ring parameters of fir (Abies pindrow) from Chandanwadi in Jammu and Kashmir, western Himalaya, India

Total ring width (TRW) and earlywood width (ERW) of fir (Abies pindrow) compared to latewood width (LRW) are strongly correlated with Palmer Drought Severity Index (PDSI) during summer season (March to October). Correlation coefficients for the period 1876-1948 between PDSI and TRW as well as ERW are 0.43 and 0.50 respectively, which is found to be significant at 0.01 level. Thereafter, their relationship weakened as temperature changed over the region, whereas maximum latewood density (MXD) reveals significant negative association with PDSI during summer season. Moreover, monthly mean, maximum and minimum temperatures during August to September of the region indicate significant positive response with MXD. Correlation coefficients of MXD with mean, maximum and minimum temperatures are 0.60, 0.61 and 0.51 respectively, which is significant at 0.01 level. There is also high temporal stability in the relationship between MXD and temperature from 1916 onwards over the region
