The t-test results suggest that the performance of SBBR was better than SBR in nitrogen and phosphorus removal at a 95% confidence interval.Two cases of recently diagnosed oesophageal squamous-cell carcinomas in men, both aged 72 years, are reported that resulted in rapid clinical deterioration and death from upper-airway occlusion and haemorrhage, respectively. In the first case, direct growth of the tumour from metastatic deposits in the paratracheal lymph nodes through the wall of the trachea resulted in lethal acute airway occlusion. In the second case, local extension of the tumour through the wall of the oesophagus into the adjacent aorta resulted in an aorto-oesophageal fistula which led to catastrophic and fatal haemorrhage. Although rare, oesophageal squamous-cell carcinomas may cause unexpected death due to quite different mechanisms, and result in the need for a detailed medico-legal assessment.A search was undertaken of the Forensic Science South Australia (FSSA), Australia, autopsy database over a 20-year period from 2000 to 2019 for all cases where vehicle crashes had involved kangaroos. There were six cases with an age range of 18-62 years (M=42 years) and a male-to-female ratio of 51. There were three crashes involving motor vehicles and three involving motorcycles. The three motor-vehicle crashes were initiated by impact with a kangaroo followed by a head-on crash with a truck (n=1) and a tree (n=2). In two of the motorcycle crashes, the cycle hit a kangaroo, resulting in the rider being unseated. In the third case, following impact with the animal, the cyclist hit a tree. In one of the latter cases, the only evidence of impact with a kangaroo was fur found by investigating officers ad
