ABSTRACT
In the present study, principal component analysis (PCA) is used to investigate the processes controlling groundwater salinity in the Mewat (Nuh) district, Haryana, India. Twenty groundwater samples were collected from salinity-affected areas in the March-April months of years 2018 and 2019 and were analyzed for chemical variables pH, EC, Ca2+, Mg2+, Na+, K+, [Formula: see text], Cl-, SO42-, [Formula: see text], TDS, and total hardness. Three principal components were selected based on the eigen value, which explains 79.58% and 85.08% of the total variation in the years 2018 and 2019, respectively. The first principal component (PC-1) is identified with salinity, the second principal component (PC-2) with alkalinity, and the third principal component (PC-3) described the pollution. When the yearly comparison was made, the samples collected in 2019 were found to have an increased salinity compared to 2018, which shows an increased vulnerability to the aquifer of Mewat on account of the decline in rainfall recharge. It was also evident that declining recharge also triggered the recharge from other sources; thus, the impact of pollution is more pronounced in 2019 compared to 2018.

This report describes the radiological features of a case of Cronkhite-Canada syndrome. Barium meal follow through with pneumocolon, used as a single radiological test, revealed diffuse polyposis involving the stomach and both the small and large intestines, as well as findings of gastric rugal thickening, whiskering, crypts and ulcerated polyps.

A 25-year-old male with severe haemophilia A developed deep vein thrombosis of the left upper limb. Venography showed thrombosis of the basilic vein. There was no underlying prothrombotic condition. He was successfully treated with low-molecular weight heparin.
