Industrial activities, through the human-induced release of Green House Gas (GHG) emissions, have beenidentified as the primary cause of global warming. Accurate and quantitative monitoring of these emissions isessential for a comprehensive understanding of their impact on the Earth’s climate and for effectively enforcingemission regulations at a large scale. This work examines the feasibility of detecting and quantifying industrialsmoke plumes using freely accessible geo-satellite imagery. The existing systemhas so many lagging factors such aslimitations in accuracy, robustness, and efficiency and these factors hinder the effectiveness in supporting timelyresponse to industrial fires. In this work, the utilization of grayscale images is done instead of traditional colorimages for smoke plume detection. The dataset was trained through a ResNet-50 model for classification and aU-Net model for segmentation. The dataset consists of images gathered by European Space Agency’s Sentinel-2 satellite constellation from a selection of industrial sites. The acquired images predominantly capture scenesof industrial locations, some of which exhibit active smoke plume emissions. The performance of the abovementionedtechniques and models is represented by their accuracy and IOU (Intersection-over-Union) *** images are first trained on the basic RGB images where their respective classification using the ResNet-50model results in an accuracy of 94.4% and segmentation using the U-Net Model with an IOU metric of 0.5 andaccuracy of 94% which leads to the detection of exact patches where the smoke plume has occurred. This work hastrained the classification model on grayscale images achieving a good increase in accuracy of 96.4%.

Cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy(CADASIL) is the most common monogenic form of cerebral small-vessel disease characterised by recurrent strokes. Behavioural disturbance also presents in a significant proportion of subjects as neurotic spectrum disorders and psychotic features are rarely reported. In this case report, we highlight a 32-year-old man with CADASIL syndrome, who had overt psychotic symptoms with neurological signs later on.

OBJECTIVE： The present study was undertaken to evaluate the effect of diosmin in diabetic neuropathy in type 2 diabetic rats. METHODS： Type 2 diabetes was induced in male Sprague-Dawley rats by single intraperitoneal injection of streptozotocin （35 mg/kg） and high-fat diet. Four weeks after the confirmation of diabetes, diabetic rats were treated with diosmin （50 and 100 mg/kg, p.o.） for next 4 weeks. Rats were evaluated for biochemical, behavioral and oxidative stress parameters. Eddy＇s hot plate and tail immersion test were performed on 6th, 7th, 8th, 9th and 10th weeks of experiment to assess thermal hyperalgesia and cold allodynia respectively. Further, the walking function test was performed for assessing the motor responses at the end of the treatment schedule. RESULTS： Rats were fed with high-fat diet throughout the experiment schedule and administration of low-dose streptozotocin induced significant elevation in blood glucose level and insulin resistance which was confirmed by oral glucose tolerance test. Treatment with diosmin at doses of 50 and 100 mg/kg significantly restored the reduced body weight, elevated blood sugar and lipid profiles. Further the dose-dependent improvement was observed in thermal hyperalgesia, cold allodynia and walking function in diabetic rats treated with diosmin. Elevated levels of malondialdehyde, and nitric oxide and decreased glutathione levels and superoxide dismutase activity in diabetic rats were restored significantly after the 4 weeks of diosmin treatment. CONCLUSION： Diosmin has shown beneficial effect in preventing the progression of early diabetic neuropathy in rats.
