this study assessed the chemical and microbial contents in the water of public swimming pools in akwa ibom state, nigeria. a total of 16 public pools were selected through probability sampling from the 32 pools that existed in the five urban areas of akwa ibom state. water samples were collected from the sampled pools and tested in the laboratory for chemical and microbial contents. results sho...

ABSTRACT- Different soil potassium (K) pools including soluble, exchangeable and non-exchangeable in surface and subsurface soils may be totally used by canola roots at different growth stages under drought conditions. A field experiment was conducted for one growing season (2013-2014) to study K pools changes during growth stages of two rapeseed cultivars under drought. The experiment was arra...

background: superficial and cutaneous fungal infections can be transmitted through using covered swimming pools. this study was conducted in order to assess the dermatophyte fungi, ph and residual chlorine levels in covered pools of yazd, iran in 2009. methods: in the current descriptive cross-sectional study, carpet sampling was used to collect 100 samples from different areas of 4 randomly se...

district of jiroft is situated in south-east of iran which is one of the malarious regions. anopheles stephensi is considered as one of the main malaria vector in this region. ecology of this species was studied in the area to understand its vector behavior for implementation of effective vector control measures. different methods like total catch, pit shelter, night bite collection on human an...

Intensive forestry has resulted in considerable increases in aboveground stand productivity including foliar and belowground biomass which are the primary sources of soil organic matter. Soil organic matter is important for the maintenance of soil physical, chemical and biological quality. Additionally, sequestering carbon (C) in soils may provide a means of mitigating increasing atmospheric ca...

This paper presents the results of the Task Committee on Canal Automation Algorithms with regard to the influence of canal properties on the controllability of irrigation canals. While the control provided by individual algorithms was not evaluated, studies were performed to illustrate inherent hydraulic limitations -the inability of canal pools to recover rapidly from disturbances or flow pert...

We tested a trait-based approach to link a soil disturbance to changes in invertebrate communities. Soils and macro-invertebrates were sampled in sandy soils contaminated by long-term wastewater irrigation, adding notably organic matter and trace metals (TM). We hypothesized that functional traits of invertebrates depict ways of exposure and that exposure routes relate to specific TM pools. Geo...
