The study aimed to determine the efficiency of a wastewater treatment plant and quality effluent discharged by into receiving water body (Okochiri River) in Eleme, Rivers State. lasted for four months. Wastewater samples were collected at various stages unit tested major parameter such as Biological Oxygen Demand (BOD), oil/grease, phenol, Dissolved (DO), Total Suspended Solids (TSS), sulphide....

eight sites were sampled during seven rain events to quantify and identify the sources ofpolycyclic aromatic hydrocarbons in urban runoff in the city of tijuana, mexico. the total σ16 pahsconcentration rangedfrom 1113 to 4866 μg/lin the sampled sites and thetotal suspended solid concentrations ranged from 7725 to 4413 μg/l. the high concentrations of total suspended solids were probably the res...

We introduce the method of punctured containers, which geometrically relates volumes and centroids of complicated solids to those of simpler punctured prismatic solids. This method goes to the heart of some of the basic properties of the sphere, and extends them in natural and significant ways to solids assembled from cylindrical wedges (Archimedean domes) and to more general solids, especially...

Nonfat dry milk and buttermilk solids used as ingredients in meat binders can be differentiated by transmission electron microscopy. The meat binders are suspended in water and coarser ingredients such as wheat and mustard flours are separated from the milk solids by low-speed centrifugation (415 g for 30 min). The milk solids thus purified are concentrated by ultracentrifugation (8 x 10 4 g fo...

Separation of solids from liquid swine manure and subsequent thermochemical conversion (TCC) of the solids fraction into oil is one way of reducing the waste strength and odor emission. Such processing also provides a potential means of producing renewable energy from animal wastes. Gravity settling and mechanical separation techniques, by means of a centrifuge and belt press, were used to remo...

We studied the association, and its direction, between the introduction of solids and weight-for-height (WFH) change between birth and 45 months. Pregnant women were asked to participate in a birth cohort during their first antenatal visit. Data from 3184 children were used. The timing of the introduction of solids was reported by the mother from a questionnaire at 12 months postpartum, and cat...

statement of problem: the guided bone regeneration (gbr) technique does not always produce consistent results. bone filling within the space provided by the membrane can be incomplete. purpose: the aim of this study was to evaluate the effect of a collagen membrane (bio-gide) in combination with or without deproteinezed bovine bone mineral (bio-oss) on the healing of calvarial defects in rabbit...
