Despite years of lack of any specific child sexual abuse laws in India, which treated them separately from adults in case of sexual offense, the Protection of Children Against Sexual Offences Bill, 2011 was passed the Indian parliament on May 22, 2012, which came into force from 14 November 2012.In Pakistan, sexual abuse of children is a problem in some madrassas. Child sexual abuse has also been reported in Madrassas across Bangladesh and India.The Kasur child sexual abuse scandal, which involved forced sex acts and an estimated 280 to 300 children, was termed the largest child abuse scandal in Pakistans history.In 2019, Pakistans Human Rights Minister, Shirin Mazari has said that Pakistan was ranked as the country with the largest numbers of child pornography viewers. Geo Pakistan, the Federal Investigation Agency, cyber-crime chief has said, "Child pornography is a business  . . with those involved in the crime linked to international child pornography rings. "In Taiwan, a survey of adolescents reported 2.5% as having experienced childhood sexual abuse.In Uzbekistan, the UK Ambassador Craig Murray wrote that the government, under president Islam Karimov, used child rape to force false confessions from prisoners.
Two different methods for the direct application of indigo dye were developed in England in the 18th century and remained in use well into the 19th century. One of these, known as china blue, involved iron(II) sulfate. After printing an insoluble form of indigo onto the fabric, the indigo was reduced to leuco-indigo in a sequence of baths of ferrous sulfate (with reoxidation to indigo in air between immersions). The china blue process could make sharp designs, but it could not produce the dark hues of other methods. In the second half of the 1850s ferrous sulfate was used as a photographic developer for collodion process images. Hydrates
Iron(II) sulfate can be found in various states of hydration, and several of these forms exist in nature. FeSO4·H2O (mineral: szomolnokite, relatively rare)
FeSO4·4H2O (mineral: rozenite, white, relatively common, may be dehydratation product of melanterite)
FeSO4·5H2O (mineral: siderotil, relatively rare)
FeSO4·6H2O (mineral: ferrohexahydrite, relatively rare)
FeSO4·7H2O (mineral: melanterite, blue-green, relatively common)
The tetrahydrate is stabilized when the temperature of aqueous solutions reaches 56.6 °C (133.9 °F). At 64.8 °C (148.6 °F) these solutions form both the tetrahydrate and monohydrate.Mineral forms are found in oxidation zones of iron-bearing ore beds, e.g. pyrite, marcasite, chalcopyrite, etc. They are also found in related environments, like coal fire sites. Many rapidly dehydrate and sometimes oxidize. Numerous other, more complex (either basic, hydrated, and/or containing additional cations) Fe(II)-bearing sulfates exist in such environments, with copiapite being a common example.
