EVALUATION OF A COMBINED SYSTEM BASED ON AN UPFLOW ANAEROBIC SLUDGE BLANKET REACTOR (UASB) AND SHALLOW POLISHING POND (SPP) FOR TEXTILE EFFLUENT TREATMENT

Abstract Color removal from textile effluents was evaluated using a laboratory-combined process based on an upflow anaerobic sludge blanket (UASB) reactor followed by a shallow polishing pond (SPP).The anaerobic reactor was fed with a real textile effluent, diluted 10-times in a 350 mg/L solution of ventilationstejp pre-treated residual yeast extra

hubbell 5362w A novel wideband multiplexer is introduced as a communications equipment solution in order to provide simultaneous operation of satellite and terrestrial services in the dedicated $K$/$Ka$ frequency bands (passbands ranging from 19.5 GHz to 30.5 GHz).Advanced RF filtering techniques are applied in order to accommodate a compact multip

Protocell multilevel selection models have been proposed to study the evolutionary dynamics of vesicles encapsulating a set of replicating, competing and mutating sequences.The frequency of the different sequence types determines protocell survival through a fitness function.One of the defining features of these models is the genetic load generated

Circumcision is among the most commonly performed surgical procedures in boys.In Morocco, this practice is often carried out by traditional practitioners, exposing patients to potentially catastrophic complications that are challenging to manage.We report the case of a 2-year-old boy who underwent doctor squish refill ritual circumcision complicate

The response of N2O emissions to nitrogen (N) addition is usually positive, but its response to phosphorus (P) addition varies, and the underlying mechanisms for the changes in N2O emissions remain unclear.We conducted field studies to examine the response of N2O emissions to N and P addition over two years in three typical alpine grasslands, alpin
