Therefore, the purpose of this study is to investigate the quality parameters of drinking water in Abadeh to determine its health. Sampling was carried out during June and November 2015 and 15 physical and chemical parameters in 20 samples in total taken from 10 drinking water resources was determined. Physical and chemical analyses were done according to the standard methods. The study of measured mean concentration showed that all measured physical and chemical parameters (Cl, EC, NO2, NO3, pH, SO4, HCO3, F, Na, Mg, Ca, TH, TDS, temperature, turbidity) of the underground water resources were desirable and met the expectations of national and international standards. The discharge of water wells has been a significant decrease in November. On the other hand, the results showed significant positive associations between EC with (Cl, SO4, HCO3, Ca, TH, and TDS), TDS with (Cl, SO4, HCO3, Ca, and TH), TH with (Cl, SO4, HCO3, and Ca,), Ca with (SO4, Cl, and HCO3), Cl with (SO4 and HCO3), SO4 with HCO3 and pH with F. However, the result showed significant negative associations between temperature with (pH and F). The quality of the drinking water of Abadeh city has a good and desirable condition, except for total hardness, although is in the standard range the water of this city is classified as hard water. .

2 - Distribution and geochemical variations among paleogene volcanic rocks from the north-central Lut block, eastern Iran

Large areas of the north-central, eastern, and western Lut block are covered by volcanic rocks of Paleogene, Neogene and Quaternary age. Peak volcanic activity took place in the north-central part of the Lut block during the Eocene, and then dramatically decreased, becoming more restricted to the eastern and western margins of the block during the late Miocene and Quaternary. There is also significant variation in chemistry between the Paleogene igneous rocks from the north-central part compared to the Neogene and Quaternary volcanic rocks from the western and eastern margins of the Lut block. The Neogene and Quaternary olivine basalts, which were erupted along both margins of the Lut block, are similar in trace element chemistry to the average composition of oceanic island basalt. In contrast, the Paleogene volcanic units of the north-central Lut block, which include basalts through rhyolites, follow both calc-alkaline and alkaline trends. Low TiO2 and high Ba/Nb and La/Nb ratios for both Paleogene basalts and andesitic samples from the north-central Lut block suggest affinities, at least for some of these samples, with convergent plate boundary arc magmas. LILE/HFSE ratios, interpreted as an indication of subduction signature, increase to the south-southwest of the central Lut block, where Neotethys oceanic crust was subducted beneath Iran in a northeastern direction from approximately Late Triassic to Late Oligocene time. We suggest that components derived from low angle subduction of this crust during the Mesozoic and early Tertiary were stored in the mantle lithosphere below the north-central Lut block until the Paleogene, when changing subduction geometry, associated with the collision of Arabia with Iran and the closing of Neotethys, caused hot asthenosphere to well up under the Lut block. This created the Eocene peak in volcanic activity, generating basalts from asthenospheric mixed with lithospheric melts, with both alkaline and calc-alkaline affinities. After this volcanism waned, becoming restricted during the Neogene to OIB-type alkaline basalts erupted through deep lithospheric structures along both the western and eastern margins of the Lut block.

The main purpose of this paper is to study the effect of Bunium persicum essential oil (BEO) stress, NaCl, bile salts, and their combinations on the viability of Lactobacillus acidophilus Bactria. In the following, the effect of BEO stress (0.5 percent), Nacl (2 percent), bile salt (0.15 percent) in comparison with the treatment instance was studied on the Lactobacillus acidophilus population in the refrigerator. Furthermore, the data analysis process was done with the two-way ANOVA and comparing the means by LSD method in SAS software version 9. The conclusions have been out coming from three-time tests with the consideration of P<0.05 in all test steps. After four weeks of 4-Celsius degree temperature conditions, the viability of Bactria and PH decreased, while the amount of degradation in the treated sample was less than the index in the stressed samples. Moreover, the amount of acidity raised in all samples and this growth in stressed samples was more than a treatment sample (P< 0.05). As a conclusion, using BEO with NaCl and bile salt in the densities below of MIC can lead to the viability of Bactria till the end of 14th-day maintenance in the probiotic product.
