"Pagans" or non-baptized children are instead assumed to be at risk from bruxas (witches), that have malignant intention themselves rather than just mau-olhado. It probably reflects the Galician folktales about the meigas or Portuguese magas, (witches), as Colonial Brazil was primarily settled by Portuguese people, in numbers greater than all Europeans to settle pre-independence United States. Those bruxas are interpreted to have taken the form of moths, often very dark, that disturb children at night and take away their energy. For that reason, Christian Brazilians often have amulets in the form of crucifixes around, beside or inside beds where children sleep. Nevertheless, older children, especially boys, that fulfill the cultural ideals of behaving extremely well (for example, having no problems whatsoever in eating well a great variety of foods, being obedient and respectful toward adults, kind, polite, studious, and demonstrating no bad blood with other children or their siblings) who unexpectedly turn into problematic adolescents or adults (for example lacking good health habits, extreme laziness or lacking motivation towards their life goals, having eating disorders, or being prone to delinquency), are said to have been victims of mau-olhado coming from parents of children whose behavior was not as admirable. Amulets that protect against mau-olhado tend to be generally resistant, mildly to strongly toxic and dark plants in specific and strategic places of a garden or the entry to a house. Those include comigo-ninguém-pode ("against-me-nobody-can"), Dieffenbachia, espada-de-são-jorge ("St. Georges sword"), Sansevieria trifasciata, and Guiné ("Guinea"), Petiveria alliacea (the guinea henweed).
This is done by addition of a teaspoon of sodium bicarbonate to cool water that was recently boiled, followed by gentle scrubbing of the eyelash base with a cotton swab dipped in the solution. Veterinary uses
Sodium bicarbonate is used as a cattle feed supplement, in particular as a buffering agent for the rumen. Cleaning agent
Sodium bicarbonate is used in a process for removing paint and corrosion called sodablasting. As a blasting medium, sodium bicarbonate is used to remove surface contamination from softer and less resilient substrates such as aluminium, copper or timber which could be damaged by silica sand abrasive media.A manufacturer recommends a paste made from baking soda with minimal water as a gentle scouring powder, and is useful in removing surface rust, as the rust forms a water-soluble compound when in a concentrated alkaline solution; cold water should be used, as hot-water solutions can corrode steel. Sodium bicarbonate attacks the thin protective oxide layer that forms on aluminium, making it unsuitable for cleaning this metal. A solution in warm water will remove the tarnish from silver when the silver is in contact with a piece of aluminium foil. Baking soda is commonly added to washing machines as a replacement for water softener and to remove odors from clothes. It is also almost as effective in removing heavy tea and coffee stains from cups as Sodium hydroxide, when diluted with warm water. During the Manhattan Project to develop the nuclear bomb in the early 1940s, the chemical toxicity of uranium was an issue.
