“…Biogas will act the part of renewable energy sources in the world. India has the second largest biogas and improved stove programme in the world (Raghuvanshi et al, 2008). For growing the biogas volume we have to understand more detailed the anaerobic fermentation process, which is determined by temperature, substrate composition, load, and toxic materials which might be presented (Schroeder, 1977;Malina and Pohland, 1992).…”

Abstract. In the course of anaerobic sludge treatment (digestion) biogas can be acquired from the sludge, its use for energetic purposes has a determinative significance in a wastewater treatment plant. The biogas, produced in the course of decomposition, covers -among others -a considerable portion of the heat-and electric energy consumption in a wastewater treatment plant, thus an increase of the biogas volume is an outstanding task. It is possible to increase the biogas volume if the anaerobic digestion processes are thoroughly well known. The anaerobic digestion process is determined by temperature, substrate composition, loading, and also by toxic substances that might be present. In our experimental work the thermophilic and mesophilic full scale anaerobic bioreactors of a communal sewage treatment plant were tested by applying usual control parameters and enzyme activity tests.

“…In the further planning of the cities, several strategies should be taken into consideration, for instance reduction, or at least mitigation of the overwintering suitability for sandfly species by decreasing human heat emission. The adequate and modest use of the renewable energy sources may also provide a mitigation chance (Raghuvanshi and Chandra, 2008 This purpose may be achieved by opening new wind tunnels, increasing the area of green spaces (green roofs, parks instead of parking places) and increasing the efficiency of thermal insulation of buildings.…”

Trájer et al.: The combined impact of urban heat island, thermal bridge effect of buildings and future climate change on the potential overwintering of Phlebotomus species in a Central European metropolis - Abstract. Leishmaniasis is one of the most important emerging vector-borne diseases in Western Eurasia. Although winter minimum temperatures limit the present geographical distribution of the vector Phlebotomus species, the heat island effect of the cities and the anthropogenic heat emission together may provide the appropriate environment for the overwintering of sand flies. We studied the climate tempering effect of thermal bridges and the heat island effect in Budapest, Hungary. Thermal imaging was used to measure the heat surplus of heat bridges. The winter heat island effect of the city was evaluated by numerical analysis of the measurements of the Aqua sensor of satellite Terra. We found that the surface temperature of thermal bridges can be at least 3-7 °C higher than the surrounding environment. The heat emission of thermal bridges and the urban heat island effect together can cause at least 10 °C higher minimum ambient temperature in winter nights than the minimum temperature of the peri-urban areas. This milder micro-climate of the built environment can enable the potential overwintering of some important European Phlebotomus species. The anthropogenic heat emission of big cities may explain the observed isolated northward populations of Phlebotomus ariasi in Paris and Phlebotomus neglectus in the agglomeration of Budapest.

“…Climate change has been one of the biggest challenges for most countries in the 21 st century. (IPCC, 2001;Raghuvanshi et al, 2008), carbon dioxide (CO2) is one of a primary interactant of global warming (IPCC, 2011; Rogelj et al, 2016). Forest sequestrate atmospheric (CO2) in the form of plant biomass during photosynthesis (IPCC, 2003;Drégelyi-Kiss et al, 2008).…”

In this study, we used radar data from the ALOS-2 PALSAR-2 satellite to build biomass estimation models and then create a biomass map in Can Gio Mangrove Biosphere Reserve. We used the single variable regression and multivariate regression method, in which 30 sample plots for training model and 15 sample plots for validation model, the coefficient of determination (R 2 ) and root mean square error (RMSE) were used as metrics for evaluating the biomass estimates. The regression analyses showed that the HV polarization was highly related to the biomass, linear model (R 2 = 0.74; RMSE = 28.16), exponential model (R 2 = 0.69; RMSE = 28.73), and polynomial model (R 2 = 0.76; RMSE = 28.03). However, the HH polarization did not show a high relationship with the above-ground biomass, linear model (R 2 = 0.42), exponential model (R 2 = 0.46), or polynomial model (R 2 = 0.42). We also tried multiple linear regression between the parameters extracted from radar image (HH, HV, and textures) and field biomass. The coefficient of determination (R 2 ) between the biomass and two independent variables (HH and HV) was 0.79, and RMSE was 29.78. However, the model with the combination of HV variable and eight texture variables provided a better result (R 2 = 0.81; RMSE = 27.76), in other word the model could explain 81% variation of forest biomass. This model was used to produce the aboveground biomass map in Can Gio Biosphere Reserve in South of Vietnam.
