The chemical looping gasification of residual biomasses—operated in fluidized beds composed oxygen-carriers—may allow the production biofuels from syngas. This biomass-to-fuel chain can contribute to mitigate climate change, avoiding accumulation greenhouse gases our atmosphere. ongoing European research project Horizon2020 CLARA (G.A. 817841) investigates wheat-straw-pellets (WSP) and raw-pine...

BACKGROUND Due to the high number of immunosuppressed and other predisposed patients hospitals have to control and ensure the microbiological water quality. The origin for the occurrence of pathogenic microorganisms in water pipes is the formation of biofilm. METHODS For the permanent control of water safety a water safety plan (WSP) was realized as recommended by the WHO following the princi...

OBJECTIVE To examine the feasibility of dimethyl sulfoxide (DMSO) incorporation into relatively hydrophilic resins as a new potential method to improve the durability of resin-dentin bonds. METHODS Six experimental light-curing BisGMA/HEMA resins solvated in ethanol and DMSO with increasing concentrations of DMSO (0, 0.5, 1, 2, 4 and 10wt%) were prepared. The degree of conversion (DC) was eva...

Significant wave height (SWH) stems from a combination of locally generated “wind-sea” and remotely “swell” waves. In the Northern Southern Hemispheres, heights typically undergo sinusoidal annual cycle, with larger SWH in winter response to seasonal changes high-latitude storm patterns that generate equatorward propagating swell. However, some locations deviate this hemispheric-scale pattern S...

With regard to water supply constraints, reuse has already become an indispensable resource. In many regions of southern Africa, so-called waste stabilisation ponds (WSP) represent a widespread method sewage disposal. Since capacity bottlenecks lead overflowing and contamination, concept was designed piloted in order upgrade plant agriculture. Using social–ecological impact assessment (SEIA), t...

nally inherited intracellular alpha-proteobacteria, known to infect a wide range of invertebrates which include insects, mites, isopods, crustaceans and filarial nematodes1. Maternal inheritances have been detected in 20–75% of the invertebrate species. Among eight major clades (A–H) of Wolbachia clades, A, B, E, F, G and H have been detected in insects, arachnids and crustaceans; while C and D...

background: data mining (dm) is an approach used in extracting valuable information from environmental processes. this research depicts a dm approach used in extracting some information from influent and effluent wastewater characteristic data of a waste stabilization pond (wsp) in birjand, a city in eastern iran. methods: multiple regression (mr) and neural network (nn) models were examined us...

Seghezzo, L. (2004), Anaerobic treatment of domestic wastewater in subtropical regions, Ph.D. thesis, Wageningen University, Wageningen, the Netherlands. In this thesis, the use of upflow anaerobic sludge bed (UASB) reactors for sewage treatment was studied in the city of Salta, northwestern Argentina. The climate in this region can be defined as subtropical with a dry season. Mean ambient temp...
