Formaldehyde is available as a gas or 40% aqueous solution called formalin. It acts as a disinfectant by alkylating proteins and nucleic acids. A 1:200 formalin solution is highly effective against bacteria, viruses and fungi, while higher concentrations and longer exposure are needed to eliminate spores. Formaldehyde has a strong odor and irritates mucous membranes. Sodium hypochlorite, commonly known as bleach, is a broad-spectrum disinfectant effective against viruses, bacteria, fungi and mycobacteria but not bacterial spores. For liquid biological waste, a 0.5% bleach solution made with a 1:10 bleach dilution is appropriate, while a 1% solution with a 1
Chlorine Dioxide (ClO2) is an extremely effective, potent, fast acting biocide that does not form any toxic by-products and leaves no residual toxicity.
It is a broad spectrum biocide that is effective against aerobic, non-aerobic, gram positive & gram negative bacteria, viruses, moulds, fungi, algae, cyst, protozoa and spore formers such as Giardia and Cryptosporidium.
It is effective across wide pH band (2 to 12).
It also removes bio film and prevents bio film formation as long as it is in use thus keeping the total water distribution clean and sanitized.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

2. FORMALDEHYDE
Formaldehyde, a gas at room temperature, is used as a fumigant or as
a 40% w/v aqueous solution containing methanol (Formalin). It acts by
alkylation of proteins and nucleic acids. The solution, in the
concentration of 1:200, is a highly effective disinfectant against several
bacteria, viruses and fungi; a higher concentration and prolonged
exposure are necessary to eliminate spores. Formaldehyde solution has a
pungent odour and is extremely irritant to the mucous membranes. It
precipitates tissue proteins in high concentration. When applied to the
unbroken skin, it hardens the epidermis.
3. Uses: A 10% solution is used for disinfection of excreta, sputa and
brush bristles. It is sometimes used in dentistry as a mummifying agent
for residual pulp tissue. A 3% solution is available for removal of warts
on the palms and soles, and a 20 to 30% solution is employed to treat
hyperhidrosis. A 4% solution in saline is a common preservative for
pathological specimens.
Formaldehyde gas is obtained by heating formaldehyde solution or
formalin tablets. It is used for sterilisation of those articles which cannot
be wetted with solutions or subjected to high temperatures. It does not
damage metal, plastics or fabrics.
4. SODIUM HYPOCHLORITE
Sodium hypochlorite, commonly known as bleach, is most frequently
used as a disinfecting agent. It is a broad-spectrum disinfectant that is
effective for the disinfection of viruses, bacteria, fungi, and
mycobacterium. However, sodium hypochlorite is NOT effective in the
disinfection of bacterial spores
5. CONCENTRATION & CONTACT TIME
The appropriate concentration of sodium hypochlorite for disinfecting general
liquid biological waste is 5000 ppm, approximately 0.5%. Household bleach
is 5 - 6 % sodium hypochlorite; therefore a 1:10 (v/v) dilution of bleach to
liquid biological waste is appropriate. For biological waste containing a high
organic load (e.g., blood, proteins, or lipids) the appropriate concentration of
sodium hypochlorite is 10000ppm, approximately 1%, therefore a 1:5 (v/v)
dilution of bleach to liquid biological waste is appropriate.
Minimum Contact time:
Surface disinfection - 1 min
Liquid waste disinfection - 20 min
Sodium hypochlorite is known to be corrosive to metals, therefore, it
important to wipe down metal surfaces with water or ethanol after treating
them with a bleach solution.
6. STABILITY & STORAGE
Bleach should be stored between 2-8°C (50-70°F). According to Clorox,
undiluted household bleach has a shelf life of six months to one year
from the date of manufacture, after which bleach degrades at a rate of
20% each year until totally degraded to salt and water, and a 1:10 bleach
solution has a shelf life of 24 hours.
Bleach must be stored separately from corrosives, soaps, detergents or
other cleaning products
7. HEALTH & SAFETY
• Skin corrosion/irritation
• Serious eye damage/eye irritation
• Acute aquatic toxicity
• Chronic aquatic toxicity
If sodium hypochlorite comes in contact with other cleaners containing
ammonia or chlorine compounds, fatal levels for ammonia gas or
chlorine gas can be produced. Never mix bleach with other chemicals.
8. HEALTH & SAFETY
Minimum Personal Protective Equipment (PPE) that MUST be worn
when preparing or handling a sodium hypochlorite solution:
Nitrile Rubber Gloves; and
Safety Glasses; and
Respiratory protection should be used any time there is the potential
for exposure to vapor and/or dust and a fume hood cannot be used;
and
Lab coat.
