Abstract Background Common subtypes seen in Chinese patients with membranous nephropathy (MN) include idiopathic membranous nephropathy (IMN) and hepatitis B virus-related membranous nephropathy (HBV-MN). However, the morphologic differences are not visible under the light microscope in certain renal biopsy tissues. Methods We propose here a deep learning-based framework for processing hyperspectral images of renal biopsy tissue to define the difference between IMN and HBV-MN based on the component of their immune complex deposition. Results The proposed framework can achieve an overall accuracy of 95.04% in classification, which also leads to better performance than support vector machine (SVM)-based algorithms. Conclusion IMN and HBV-MN can be correctly separated via the deep learning framework using hyperspectral imagery. Our results suggest the potential of the deep learning algorithm as a new method to aid in the diagnosis of MN.

An experiment was conducted to investigate the effect of standing water levels on methane gas emission and yield of transplanted Aman rice (cv. BRRI dhan51) during July to December 2015 at medium low-lying area of Mohangonj upazila under Netrokona district. The experiment comprised five standing water levels on surface paddy soil viz., 5 cm, 10 cm, 15 cm, 20 cm and 25 cm. Methane (CH4) gas emission, yield components and yield of transplanted Aman rice were significantly affected by standing water levels on surface paddy soil. CH4 emission was gradually increased with rising standing water levels and remained static condition at 20-25 cm water level.  The highest CH4 emission was observed at 20 cm standing water level and the lowest CH4 emission was recorded at 5 cm water level. The highest CH4   peak recorded at 85 days after transplanting (DAT). The highest CH4 flux (36.59 mg/m2/h) was observed in treatment 20 cm water level whereas the lowest CH4flux (21.17 mg/m2/h) was observed in 5 cm water level.  Finally, the CH4 emission dropped at 108 DAT. On and average, the CH4 emission rate during rice cultivation followed 20 cm > 25 cm> 15 cm > 10 cm > 5 cm water level. Soil Eh gradually decreased with progress of time and plant growth and at 85 DAT highly reduced condition developed in all treatments. The maximum reduced condition was observed (-238.67 mV) in treatment 20 cm water level and minimum one (- 214.667 mV) was found in 5 cm water level. The highest grain (5260 kg ha-1) and straw (6725.0 kg ha-1) yields were obtained at 10 cm standing water level while the lowest grain (4191.6 kg ha-1) and straw (5050.0 kg ha-1) yields were recorded in 5 cm and 15 cm water level, respectively. It may be concluded that 10 cm standing water level is beneficial for transplant Aman rice (cv. BRRI dhan51) cultivation in low lying area in respect of grain yield and environmental issues.

Abstract Purpose-Fish waste affects the area surrounding and can change a broad oceanfront zone at unlike environment levels by its effluent. In order to reduce the environmental impacts of improper disposal of both fish waste and sewage in the vicinity of the fishing industry in the coastal zone, an attempt has been made to convert the mixture of fish waste and sewage into energy.Findings-The by-product wastes mainly head, bones, skin, gut, tail and sometimes full whole fish waste. The main composition of fish waste is Protein 65%, fat 18% and minerals 17%. So fish waste having a large amount of biodegradable matter when compared to fresh sewage and also by adding higher amount of fish waste we can able to generate higher methane emissions. Methodology-The ultimate aim of the project is to find the optimum methane gas emission from fish waste mixed with fresh sewage using the anaerobic digestion for the experimental part. And for the stoichiometry combustion equation for the theoretical part.Value-Using stoichiometries equations methane gas generated has been calculated from the mixture of sewage and fish waste. Using the Orsat’s apparatus methane gas generated hasbeen measured from the mixture of sewage and fish waste. The correlation coefficient - R2 value is 0.9906 indicating a strong correlation for the predicted values and the measured values.

<p>The Increase of temperature in atmosphere caused by increasing concentrations of methane in rice field affects to metabolism of rice plants, it can reduce productivity of rice. <em>Methanotrofic</em> bacteria are one of the organisms that can reduce methane gas emissions, because the bacteria use methane as an energy source. Based on the fact, needed information about the reduce potential of methane gas by the bacteria. The aim of this study was to analyze reduce potential of <em>methanotrofic</em> bacteria have been previously isolated that from rice fields in Gowa. The Analysis was done by measuring concentration of methane gas using chromatography gas techniques. Observations of remaining gas concentration were done four times during 13-days incubation period. All isolates were able to reduce methane with varies potential. The highest reduction shown by isolates GMP 2 with the reduction about 88%. The Lowest reduction shown by GMV 3 with the reduction about 51.9%.</p><p><strong>Keywords</strong>: emission, methane, <em>methanotrofic</em></p>
