Drinking of original mineral water "Naftussya" from Truskavets spa by the healthy adult rats during 3 weeks led to increase the urinary, biliary, cholates and cholesterol extraction by 54%, 72%, 69% and 83%, respectively with no influence on the enteric water absorption. The integral activity index was 2.55 +/- 0.21. Ultrafiltration of mineral water in order to eliminate microflora did not affect significantly tested properties (2.29 +/- 0.21) while ultra-violet irradiation of water increased the integral activity index to 2.67 +/- 0.47 due to enhancement of water absorption on 48% in the small intestine and increase of diuresis on 88% as well as biliary, cholesterol and cholates extraction on 74%.

In this study, kaolinite-poly(urea-formaldehyde) was successfully prepared through the polymerization of urea intercalated within the kaolinite structure. Polymerization was carried out under ambient conditions by immersing kaolinite-urea in formaldehyde. Evidence of urea intercalation and polymerization was obtained from FTIR, XRD, and thermal analysis (TG-DSC).

Sport participation affects body composition and bone health, but the association between sport, body composition, and bone health in female athletes is complex. We compared areal bone mineral density (aBMD, DXA) and tibial volumetric bone mineral density (vBMD), geometry, microarchitecture, and estimated strength (HR-pQCT) in cross-country runners (n = 22), gymnasts (n = 23) and lacrosse players (n = 35), and investigated associations of total body lean mass (TBLM), team, and their interaction with tibial bone outcomes. Total body (TB), total hip (TH), femoral neck (FN), and lumbar spine (LS) aBMD were higher in gymnasts than runners (p < 0.

Evaporation or freezing of water-rich fluids with dilute concentrations of dissolved salts can produce brines, as observed in closed basins on Earth and detected by remote sensing on icy bodies in the outer Solar System. The mineralogical evolution of these brines is well understood in regard to terrestrial environments, but poorly constrained for extraterrestrial systems owing to a lack of direct sampling. Here we report the occurrence of salt minerals in samples of the asteroid (101955) Bennu returned by the OSIRIS-REx mission.

The sustainable material, biochar (BC) from a hardwood source, was synthesized via pyrolysis process at 400 °C (BC400) and 700 °C (BC700) and used as a modifier during the electrochemical sensor design. The prepared BCs were characterized by scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) analysis, and elemental analysis (CHNS). The development of rapid analytical techniques for detecting pesticides employing a low-cost carbon paste electrode (CPE) modified with BC is a novel strategy to provide a sensitive response to water pollution.
