Water is made up of two hydrogen atoms and one oxygen atom, with a molecular weight of 18 units. Water exists in three states: liquid, gas, and solid ice. It freezes at 0°C and boils at 100°C. There are several types of water including hydrogen peroxide, distilled water, and hard water containing dissolved salts. Water can dissolve many substances like hydroxides, some carbohydrates, and some salts.
Although nutrients, nitrogen and phosphorus in particular, are essential for aquatic life, too many nutrients can create significant problems for our nation’s lakes, streams, and coastal waters. Nutrient pollution can degrade habitat for fish and wildlife, render water bodies unsafe for swimming and other forms of contact recreation, create a public health concern for drinking water supplies, decrease property values, and negatively impact local economies. According to national statistics, more than 45% of streams have medium to high levels of nutrients, approximately four million lake acres have been identified as threatened or impaired, and approximately 78% of assessed coastal areas exhibit signs of eutrophication.

A large amount of water is discharged back after domestic and industrial usage.
Contamination upon reaching beyond certain allowed concentrations is termed pollution and the contaminants are called the pollutants.
If the concentration of substances naturally present in water increases then also the water is said to be polluted.
Water pollution may be defined as the contamination of streams, lakes, seas, underground water, or oceans by substances, which are harmful to living beings.

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”.

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.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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.

1. WATER IN CHEMISTRY
Water- H20 It consists of two hydrogen atoms and one oxygen atom. Molecular weight of two hydrogen
atoms is 2u, 16u of oxygen.
The molecular weight of water is 18U. Location on the periodic table. Hydrogen is the first main group, in
the first period. Oxygen is in the 16th group (6th main group), in 2nd period.
2. ●
Temperatures:
●
At 4 degrees Celsius oxygen is dissolved in water.
●
Water freezes at 0 degrees Celsius and boils at 100 degrees Celsius.
●
●
Water exists in three states of matter.
●
Liquid (water)
●
Gaseous (water vapor)
●
Solid state (ice)
3. Several types of water:
- Hydrogen peroxide - 3% aqueous hydrogen peroxide solution used to disinfection
