This study evaluated, in vitro, the effect of iron (previously exposed with enamel powder or added directly to the beverage) on the erosive potential of carbonated or decarbonated beverage. Four sets of experiments were done. For groups E1 and E3, a solution containing 30 mmol/L FeSO4 was added to bovine enamel powder (particles between 75-106 mm) before exposure to the carbonated or decarbonat...

BACKGROUND Bottles containing carbonated drinks are potentially hazardous to the eye. In this study, we aimed to document the clinical characteristics and visual outcomes in a series of patients with ocular injury from flying metal caps of carbonated mineral water bottles. METHODS Retrospective review of ocular injuries due to metal caps of carbonated mineral water bottles. RESULTS Sixteen ...

Abstract Natural fractures play an essential role in the characterization and modeling of hydrocarbon reservoirs. Modeling fractured reservoirs requires understanding fracture characteristics. Fractured zones can be detected by using seismic data, petrophysical logs, well tests, drilling mud loss history core description. In this study, feed-forward neural networks (FFNN), cascade feed forward ...

Caffeine is a natural substance present in leaves and seeds of many plants. The aim of this study is to evaluate the caffeine level in the carbonated drinks from the Romanian market. For this survey were taken 30 samples of different carbonated drinks. The caffeine was determined and quantified using a HPLC with diode array detector at 206 nm. The caffeine retention time was at 17.785 minutes. ...

Microstructural characteristics and biocompatibility of a Type-B carbonated hydroxyapatite (HA) coating prepared on NiTi SMA by biomimetic deposition were characterized using XRD, SEM, XPS, FTIR and in vitro studies including hemolysis test, MTT cytotoxicity test and fibroblasts cytocompatibility test. It is found CO(3)(2-) groups were present as substitution of PO(4)(3-) anions in HA crystal l...
