River channels and their flood plains are among the most naturally dynamic ecosystems on earth, in large part due to periodic flooding. The components of a river's natural flood regime (magnitude, frequency, duration and timing of peak flows) interact to maintain great habitat heterogeneity and to promote high species diversity and ecosystem productivity. Flood regimes vary within and among riv...

River pollution in Taiwan is rather serious, but so far there have been no reports of fish intersex problems. This report reveals that 50% male tilapia in the Era-Jiin River of southern Taiwan were found to be feminized in an October 8, 1994 collection from station EJ-2 of this river. After discounting all other possible causative factors, and correlating with endocrine disrupting chemicals fou...

Abstract Stable isotope composition of ?2H and ?18O was investigated in the water resources Shwan sub-Basin northeast Iraq. The study objects conceived possible factors that affect stable isotopes’ precipitation additionally to achieve information concerning recharge processes estimate groundwater sources. In this study, four samples were collected at area for 2020–2021 hydrological year. Thirt...

This study included an assessment of the hydrogeological conditions Mishraq sulphur fields before production, by measuring groundwater levels in (11) wells Mishraq-2 2021, as well information obtained, which are (12) Mishraq-3, (68) Mishraq-1. Groundwater ranged between (187.71-205.80) m Mishraq-1, while it (189.19-196.26) m, for Mishraq-3 were (186.4-194.98) m.
 The contour maps drawn mov...

River systems are valuable to human beings; meanwhile, they are intensively influenced by human activities, especially urbanization. In this study, based on the data derived from topographic maps and remote sensing images, the temporal and spatial change of river system geomorphology in the Taihu Region over the past 50 years was investigated in conjunction with urbanization. Results demonstrat...

Abstract The design of the efficient, flexible air electrode for enhancing Zn‐air batteries (ZABs) performance is vital in developing a new portable rechargeable power supply. Emerging research indicates that non‐precious metal materials have promising activity oxygen reduction/evolution alkaline conditions while constructing high‐performance and reliable still big challenge at present stage. I...

This study was designed to determine whether diurnal patterns of blood pressure, heart rate, or locomotor activity differed among two substrains of Wistar-Kyoto rats, derived originally from Charles River or Taconic Farms stock, or the spontaneously hypertensive rat. Cardiovascular parameters were continuously monitored over 24 hours. Resting systolic and diastolic blood pressure values were st...
