In the first volume of his Physical and chemical essays (1779), Torbern Bergman, professor of chemistry and pharmacy at Uppsala in Sweden, discussed the chemical analysis of natural waters, including mineral waters. He remarked that when a weighed quantity of a mineral water was evaporated to dryness the weight of the residues usually amounted to no more than a minute fraction of the original w...

OBJECTIVE Considering that water is an importance source of fluoride intake, and that the consumption of mineral water and prevalence of dental fluorosis have been increasing, the aim of this study was to evaluate the consumption of mineral water and its fluoride concentration. METHODS The study was performed in residential districts of the municipality of Bauru, State of São Paulo, by means ...

This study was designed to investigate the possible effects of consuming Na-rich carbonated mineral water on bone remodelling and urinary mineral excretion in postmenopausal women. Women (n 18) included were amenorrhoeic (>1 year), healthy and not obese (BMI <30 kg/m2). No woman was taking oestrogen replacement therapy, mineral and vitamin supplements, phyto-oestrogens or medications known to a...

water injection is an enhanced oil recovery method which is applied for number of reservoirs especially in the offshore fields around the world. sea-water injection process is usually associated with important concerns affecting the efficiency, safety, and economy of the operation like formation damage, mineral scaling, early breakthrough and corrosion. incompatibility between injected and form...

The major "benefit" alleged to accrue from transpiration (the evaporative loss of water from plant surfaces) is that it is essential for the long-distance transport of mineral ions, but the possible interrelation between these two processes has rarely been tested. Transpiration was experimentally dissociated from mineral supply by growing sunflowers (Helianthus anuus) in hydroculture and provid...

The microbiological quality of five brands of carbonated and non-carbonated mineral water sold in Poland was studied. The study was carried out on the survival of heterotrophic bacteria at 22 and 37 degrees C (pour plate technique) in the samples of mineral waters stored at 4 and 22 degrees C. The one hundred ten bottles (twenty two bottles of each of the five brands) of carbonated and uncarbon...

AIMS Osteoarthritis is the most degenerative joint disease. The aim was to investigate the effects of ultrasound using mineral water or aqua sonic gel on severity of knee pain, measured by the visual analog scale and the Western Ontario and McMaster Universities Arthritis Index (WOMAC). MATERIALS AND METHODS Thirty women with bilateral osteoarthritis of the knee were assigned to two groups: u...

background and objectives: availability and uptake of mineral by explants are recognized as being important in tissue culture. the limiting factor for maximum mineral uptake and optimum growth is that minerals are not enough available to the explants. there are the inter-relationships between plant growth, mineral uptake, medium water potential, and mineral movement through the medium. plantlet...
