Generally soaps create foam in water, but in present of some materials the foam creation is reduced and need more soap for producing foam, and this condition of water is called water hardness.
The presence of Calcium, Magnesium salt i.e. bicarbonates, sulphates, chloride in water is called causes of hardness of water. The water which contains these salts is called hard water. Hard water does not easily form lather with soap as the salt of Calcium and Magnesium react with soap to form insoluble organic salts.

Water treatment procedure also vary depending upon its use. However, overall picture of water treatment, irrespective of end use shall be considered. An endeavor is made to comprehend the basic chemistry involved in water treatment process. The important stages involved in treatment are as follows: coagulation or flocculation; sedimentation; filtration – slow sand, rapid sand filtration; disinfection – including chlorination and ozonolysis; removal of iron and manganese; softening by lime-soda ash process or deionization method; scale and corrosion control; taste and odor removal; prophylaxiation treatment, i.e., fluoridisation; and specialized treatment for a specific purpose.
The fashion industry relies entirely on water for textile and garment manufacturing processes. It takes an average of 10,000 liters of water to grow just one kilogram of raw cotton, with cotton being used to make one-third of the textile produced worldwide (and it represents 90% of the natural fibers used).

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Boiler water treatment
Boiler water treatment is a type of industrial water treatment
focused on removal or chemical modification of substances
potentially damaging to the boiler.
It is used to control alkalinity, prevent scaling, correct pH, and to
control conductivity.
The main objectives to treat and condition boiler water is to
exchange heat without scaling, protect against scaling and produce
high quality steam.
Internal treatment is for boiler feed water External treatment is for make up feed water
4. Scale and sludge
Scale Sludge
Definition Scale is a hard adhering crust/coating on
the inner walls of the boiler.
Sludge is a soft, loose and slimy
precipitate formed on the inner walls of
the boiler.
Disadvantages 1.Wastage of fuel
2.Lowering of boiler safety
3.Decrease in efficiency
4.Danger explosion
1.Wastage of fuel
2.Choking of pipes
Prevention Dissolving by adding chemicals
By using well softened water
By using well softened water
By frequently blow down operation
