The increase in spatial data for location-based service (LBS) in mobile computing or geographic information system (GIS) has led to more research on spatial indexing, such as R-tree. Nevertheless, few studies have attempted to improve performance by reducing the size of the index. If the minimal bounding rectangles (MBRs) that represent objects in R-tree are compressed, the index size is reduce...

The catalytic inefficiencies of the CO2-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) often limit plant productivity. Strategies to engineer more efficient plant Rubiscos have been hampered by evolutionary constraints, prompting interest in Rubisco isoforms from non-photosynthetic organisms. The methanogenic archaeon Methanococcoides burtonii contains a Rubisco isoform...

The use of granule activated carbon (GAC) and rubber particles as the bio-fouling reducer in a membrane bioreactor (MBR) was evaluated this study. addition GAC tends to temporarily reduce Transmembrane Pressure (TMP). Then, after initial reduction, TMP gradually increased back up 0.7 bar, indicating significant fouling on membrane. Low values were observed adding 0.5% (V/V) same MBR. organic co...

We study the magnetic-based motion control of a sperm-flagella driven Micro-Bio-Robot (MBR), and demonstrate precise point-to-point closed-loop motion control under the influence of the controlled magnetic field lines. This MBR consists of a bovine spermatozoon that is captured inside Ti/Fe nanomembranes. The nanomembranes are rolled-up into a 50 μm long microtube with a Islam S. M. Khalil and ...

The presence of pharmaceutical drugs and residues in wastewaters is of concern due the potential health and environmental risks when the wastewater is recycled as an alternative water source. This study investigated the application of an integrated membrane bioreactor with titanium dioxide photocatalytic technology (MBR-TiO2), as a combined treatment barrier to remove Carbamazepine (CBZ) from p...

The operation of an activated sludge process at a paper mill (AIPM) in Hedera, Israel, was often characterized by disturbances. As part of a research and development project, a study on new biological treatment was initiated. The study included the operation of three pilot units: a. anaerobic treatment by upflow anaerobic sludge blanket (UASB); b. aerobic treatment by two pilot units including ...

Benzodiazepine binding sites were studied in mitochondria of unicellular eukaryotes, the amoeba Acathamoeba castellanii and the yeast Saccharomyces cerevisiae, and also in rat liver mitochondria as a control. For that purpose we applied Ro5-4864, a well-known ligand of the mitochondrial benzodiazepine receptor (MBR) present in mammalian mitochondria. The levels of specific [(3)H]Ro5-4864 bindin...

With stringent wastewater discharge limits on nitrogen and phosphorus, membrane bioreactor (MBR) technology is gaining popularity for advanced wastewater treatment due to higher effluent quality and smaller footprint. However, higher energy intensity required for MBR plants and increased operational costs for nutrient removal limit wide application of the MBR technology. Conventional nitrogen r...

introductioncurrently, treated industrial wastewater is discharged to the environment in most industrial towns in iran. it is, however, a potential water resource for produce industrial process water. for reach this reuse application, further treatment would be needed. nowadays membrane separation processes are becoming quite popular in wastewater treatment and reclamation, since they combine p...
