Analysis was carried out on the physico-chemical parameters measured at two stations, Thondi and Soliyakudi in the southeast Palk Strait region during the monsoon and post monsoon seasons (November 2008-March 2009). High temperature (31˚C) and salinity (35%o) were recorded in the month of March (post monsoon). During the monsoonal season, dissolved oxygen content was found to be high (5.2 O2 mg l-1) and the total phosphorous concentration when compared to other nutrients such as NO3, NO2 and SiO2, was also high in both the stations. In general, concentrations of all the nutrients were high in Thondi during the monsoon season (November and December) which could be due to the addition of nutrients through the sewage, agricultural and land run off.

Human cancer is one of the world’s most deadly diseases caused due to genetic disruption of skin cells and several molecular mutations. Skin cancer remains the most predominant form of cancer in human beings. The major goal is to detect skin cancer in early stages by research and analyse it using various techniques such as segmentation and feature extraction. The diagnosis of malignant melanoma skin cancer is done by dermatologist by examining skin and physical biopsy to determine the accurate stage of melanoma. It is developed because of high accumulation of melanin in the dermis layer of the skin. ABCD law is used in along with dermoscopy technology to detect malignant melanoma skin cancer. Image Acquisition Technique, pre-processing, segmentation, distinguishing function for skin Feature Selection, which specifies lesion characterization and classification methods are all conducted in this project for melanoma skin lesion characterization. We used symmetry detection, border detection, colour and diameter detection, as well as feature extraction to remove texture based features using a digital image processing technique. The deep Neural Network was proposed here to characterize the benign or malignant stage.

May–Thurner syndrome is a rare cause of left iliac deep vein thrombosis due to an anatomical variant in which right common iliac artery overlies and compresses left common iliac vein against lumbar spine. Patients with May–Thurner syndrome usually present in their 2nd to 4th decade of life. Pregnancy and intra-abdominal surgeries are known precipitating factors in acute May–Thurner syndrome. We report the case of a woman in her 3rd decade of life who presented with May–Thurner syndrome following total abdominal hysterectomy. This case report hopes to bring attention to the high variant of patient population with May–Thurner syndrome and the necessity for surgical intervention of stent placement to prevent recurrence.
