Museum collection of endangered freshwater pearl mussel (Margaritifera margaritifera) shells was studied. The ontogenetic ages of the mussels were estimated to be between 12 and 178 years. Information from shell increments, morphometry and taphonomy was combined into age-dependent life-trait reconstructions that were modelled using linear and non-linear growth functions. Nearly all the life-tra...

A shallow geothermal reservoir in the Pueblo of Jemez in New Mexico may indicate a commercialscale geothermal energy potential in the area. To explore the geothermal resource at Jemez Pueblo, seismic surveys are conducted along three lines for the purpose of imaging complex subsurface structures near the Indian Springs fault zone. A 3-D magneto-telluric (MT) survey is also carried out in the sa...

The hydrogeochemical characteristics of groundwater are an important element in the study spatial and temporal variation resources, which is crucial to water resources utilization, ecological environmental protection, human development. Water samples were collected at eight observation Nandong Karst System (NKWS) sites each month 2019, main ions isotopes examined. hydrogeochemistry its differen...

since its advent in 1867,the arabic novel has been under the influence of two factors. one factor is longing for the past, the other one is infatuation with the west and submission to its hegemony. in early 20th century, some novels were written in response to public taste and arab culture. this novel is considered by critics of fiction to be a turning point in the path of arabic fiction. at th...

Hydrogeochemistry of 32 hot springs in the western Sichuan Province after the Wenchuan MS 8.0 earthquake was investigated by analyzing the concentrations of cation and anion and the isotopic compositions of hydrogen and oxygen. The water samples of the hot springs were collected four times from June 2008 to April 2010. Hydrogeochemical data indicated the water samples can be classified into 9 c...

The study was carried out in Gwoza town of Borno Sate to assess the chemistry groundwater Local Government. Eighteen (18) samples were collected for purpose this study; analyzed their physical parameters at spot using field kits combined pH/EC/TDS/Temperature meter model Mi 806 also used measuring parameters. GPS locating sampling points. Sodium and Potassium by flame photometry method; Calcium...
