A field experiment was conducted to (i) examine the diurnal and seasonal soil carbon dioxide (CO(2)) fluxes pattern in rice paddy fields in central China and (ii) assess the role of floodwater in controlling the emissions of CO(2) from soil and floodwater in intermittently draining rice paddy soil. The soil CO(2) flux rates ranged from -0.45 to 8.62 µmol.m(-2).s(-1) during the rice-growing seas...

Soils that are exposed to floodwaters because of shallow groundwater and periodical wetlands are, to a large extent, exposed to contamination by organic and inorganic compounds. These are mainly compounds that have drifted along with the inflow of heavily laden floodwater and are produced within the soil profile by the anaerobic transformation of organic matter. Heavy metals and polycyclic arom...

Floodwater mosquitoes lay their eggs on dry ground where water will eventuallyflood the area. By flooding area and submerging of floodwater mosquitoes, development larvae begins. For a gravid female mosquito, mostimportant thing is choosing place to eggs. As part this research,which was conducted in April May 2022, soil leaf samples were taken anarea 50 x cm from different altitudes Dunavac nea...

This paper demonstrates a biologicallyand psychologicallyinspired human-like computational memory focusing on the retrieval mechanisms – Spreading Activation and Compound Cue for a companion agent’s episodic memory (EM) that helps the agent to manage it’s memory more efficiently and enable it to have a more natural interaction with the user.

flood spreading has an effective role in the soil improvement and fertility, ground water storage, revival of vegetation and prevention of fluent sands movement. one of the main problem of flood spreading projects is the entrance of sediment to the spreading systems and sedimentation in it. sediment reduces the efficiency of the flood spreading system and after awhile lose its efficiency.the ma...

Recent research has shown that the Faynan Orefield was a scene of intensive metal production during Classical Period, but infrastructure supporting this activity is less well known. We present evidence for previously undetected floodwater-farming and quarrying, which contributed to economic life complex times. The site located on an ancient route, south main orefield. describe hydrological cont...
