Coastal solar saltworks of Brazil are exploited for sea salt, which becomes progressively concentrated by evaporation. This study aimed to review the current and new potential uses of these systems, in order to provide more dynamic for this activity. The first evaporation ponds are also used for artisanal fisheries, ensuring the livelihood of many families. All the brine rich in secondary salts...
Dibenzo-2 1-crown-7 (DB2IC7) and dibenzo-24-crown-8 (DB24C8) have been used to extract the metal ions (Na+. K+. Mg2+ and Ca2+) present in bittern, schoenite and in an artificial solution containing equimolar amount of the above mentioned metal ions. Ion chromatographic study of the organic extract shows that DB21 C7 extracts potassium with hi gh selectivity, whereas DB24C8 extracts comparable a...
DNA-DNA hybridization was used to discover the extent of single-copy DNA similarity among 13 species of herons and one ibis. Genetic distances among taxa were summarized as Tm values in a folded matrix. From this matrix, trees with the same branching pattern were constructed by least squares under one of two assumptions: (1) that sister branches are equal in length and (2) that sister branches ...
Removal of Boron from the Bittern Solution of Lake Qarun Water by Electrically Assisted Ion Exchange
The purpose of this study was to analyze whether seawater has positive effects on appearance characteristics, such as redness, and determine the gas composition concentration that is suitable for maintaining it. Pork hind meat cured with four types brine five days at 4°C. different brines comprised control salt (CS), nitrite pickling (CN), treatment (BR), bittern (BT). hams were cooked 65°C 4 h...
Investigating how Mediterranean wetlands respond to adjacent land use conversion, is an important first step in mitigating the impact of human encroachment and other environmental stressors. We monitored composition structure waterbird assemblages, a urban marsh, subjected severe anthropogenic pressures. Remote sensing indicated that last two decades Boussedra Pond was landfill, resulting subst...
