The elemental analysis of the samples collected from marshes water and river water in Thi Qar region of Iraq are done using the X-ray fluorescence technique (XRF). The water samples are collected from Euphrates River, Al- Hammar marshes, ground water and drinking water. The elements observed in various samples are 20Ca, 26Fe, 29Cu, 30Zn, 33As, 35Br and 38Sr. The 20Ca concentration in Euphrates river water constitutes ͂ 2.3% of the left over residue, a value similar to that observed in water from the marshes. The 38Sr concentrations in the Euphrates river water is in the range 2519-5691μg/L. The 38Sr concentrations in Euphrates River are similar to that observed in the marshes water. In Al-Hammar marshes, the concentration of 34As is estimated to be in general below 5 μg/L. The 35Br concentration in various samples collected from Al-Hammar marshes are in the average value =1108 μg/L. The 35Br concentration in various samples collected from Euphrates river are in the average value =676μg/L. The water from Euphrates river is not safe for use for drinking water supply due to high bromine content and the water from the drinking water schemes from the river needs to be monitored for the presence of bromate ions.

An investigation was carried out to assess the water qualities and extents of impurities in groundwater and surface water (Padma river water) in Rajshahi City area. Water samples from a total of 330 tube wells and five spots of the river Padma were analysed for physicochemical, biological and hydrological parameters with standard methods. Among all considered parameters of ground water, concentrations of arsenic, iron, manganese, total hardness, and total coliform and faecal coliform bacteria were found above the permissible limits for potable water. In case of the river Padma, biochemical oxygen demand, chemical oxygen demand, total coliform, faecal coliform and suspended solids exceeded permissible limits. Both ground and river water must be treated properly before distribution for drinking purpose. Finally, the Padma is recommended as the most sustainable drinking water source for Rajshahi City Corporation area. Keywords: Rajshahi City; Ground water; Surface water; Quality control. © 2010 JSR Publications.

Water is the most important source of minerals for both human beings and animals. But at the same time, water is also a source of disease due to the contamination of various elements. Therefore, knowledge of the elemental content of water is important. In this work, water samples were collected from areas around Chandigarh and Bathinda district, Panjab, India. Proton-induced X-ray emission (PIXE) and proton-induced gamma-ray emission (PIGE) techniques were used for the determination of heavy and light trace elements, respectively, in wide varieties of water samples. A large number of elements, namely F, Na, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Cu, Zn, As, Pb , and U were detected in the samples and results are discussed.

The microstructure, revealed by X-ray diffraction and transmission Mössbauer spectroscopy, magnetization versus temperature, external magnetizing field induction and mechanical hardness of the as-quenched Fe75Zr4Ti3Cu1B17 amorphous alloy with two refractory metals (Zr, Ti) have been measured. The X-ray diffraction is consistent with the Mössbauer spectra and is characteristic of a single-phase amorphous ferromagnet. The Curie point of the alloy is about 455 K, and the peak value of the isothermal magnetic entropy change, derived from the magnetization versus external magnetizing field induction curves, equals 1.7 J·kg−1·K−1. The refrigerant capacity of this alloy exhibits the linear dependence on the maximum magnetizing induction (Bm) and reaches a value of 110 J·kg−1 at Bm = 2 T. The average value of the instrumental hardness (HVIT) is about 14.5 GPa and is superior to other crystalline Fe-based metallic materials measured under the same conditions. HVIT does not change drastically, and the only statistically acceptable changes are visibly proving the single-phase character of the material.

The results on elemental analysis of the vietnamese ancient bronze coins during the time of the Nguyen dynasty (19th century) are presented. The samples were provided by the Vietnam National Historical Museum and the elemental analysis was performed on the home-made model EDS-XT-99-01 X-ray fluorescence spectrometer in the Institute of Materials Science, NCST of Vietnam. The samples exited simultaneously by radioisotope source and X-ray tube. The analytical results show the similarity in the elemental composition of the coins issued by different kings of the Nguyen dynasty, but there is the difference in the concentration of the used elements. Another interesting point is that all the coins have zinc (Zn) in their composition, which shows clearly the influence of the occidental metallurgical technology on the money-making technique in Vietnam during the 19th century.

The Difference

The Difference in Average DMF-T in Communities that Consume Refillable Bottled Drinking Water and Precipitated River Water. The average DMF-T index for Indonesia is 4.6 with a value of D-T component is 1.6, M-T component is 2.9, and an F-T component is 0.08. It means, tooth decay in Indonesian people is 460 teeth per 100 people (Riskesdas., 2013). The DMF-T index for Provinsi Kalimantan Selatan is 6.83, with a value of D-T component is 1.31, M-T component is 5.52, and F-T component is 0.12. It means, the average of tooth decay per person (severity of teeth per person) is 6.83 teeth or 7 teeth (Riskesdas., 2007). This study aimed to determine the difference of DMF-T average in people who consumed refillable bottled water and people who consumed river water treated by deposited, in Desa Samuda, Kecamatan Daha Selatan, Kabupaten Hulu Sungai Selatan, Provinsi Kalimantan Selatan. This research was an analytical survey with cross sectional approach. The sample of this research was all of the people in Desa Samuda, Kecamatan Daha Selatan, Kabupaten Hulu Sungai Selatan, as 110 participants. The independent variable was refilled bottled drinking water and deposited river water. The results showed that the DMF-T average in people who consumed refillable bottled water was 6.42 and the DMF-T average in people who consumed deposited river water was 8.20. Based on the result of the Independent T-Test, the value of sig (2-tailed) p = 0.004 was less than α = 0.05; (p<α), meaning that Ho was rejected and Ha was accepted. The conclusion is that there are the differences of DMF-T average in people who consume refilled bottled drinking water and deposited river water. It is recommended that people who consume deposited river water conduct drinking water treatment that complies with health standards.
