In order to study the suitability of composting olive mill wastewater (OMW-L) by repeated applications, OMW-L was added to one mixture of lawn trimmings and olive husks as bulking agents. The composting process of this mixture was compared with another pile having 35% of olive mill wastewater sludge (OMW-S) obtained from evaporation ponds and a third, as a control, without olive mill wastewater. The repeated applications of OMW-L resulted in a sharp decrease in respiration measurements after the first 20 days of composting and showed a re-increase after 40 days following the substituting of OMW-L by water. The OMW-L addition increased the rate of water-soluble phenols in the compost and caused the appearance of a phenol fraction of high molecular-mass (510 kDa) at the end of composting. OMW-L addition also caused a clear decrease in both thermophilic bacteria and thermophilic eumycete counts. A longer persistence of phytotoxicity was observed in comparison with the other piles. However, the OMW-S produced a compost with a high degree of maturity. 相似文献

Behavioural observations of male copepods revealed that they commonly follow female footprints to find their mates. Copepods
can perceive signals generated by females either hydromechanically or chemically. Signal intensity is affected by hydrodynamic
conditions which clear chemical and mechanical cues and modulate copepod’s ability to sense signals of their biotic environment,
such as in their search for mates. We studied the patterns and efficiency of the copepod Pseudodiaptomus annandalei to mate in calm and hydrodynamically disturbed waters, in illuminated and dark conditions in experimental containers of different
shapes and volumes. Courtship in P. annandalei was a negative function of hydromechanical disturbance, since successful mating events were observed in calm water only.
In weakly turbulent conditions (air-bubbling of 100 ml/min), males were not able to pursue females properly; swimming speed
decreased about three times in comparison with that in calm water. In calm water conditions, sequential and simultaneous taxis
mechanisms were used by P. annandalei males to pursue females. The ability of P. annandalei males to track a three-dimensional trail probably depended on the persistence of fluid-borne signals. 相似文献
