It is a type of quantitative analysis that involves weighing of the constituent under determination.
Or
It is the process of isolating and weighing an element or compound in a pure form.
Or
Gravimetric methods of analysis are based on the measurement of mass.
Electrogravimetry, we deposit the analyte as a solid film an electrode in an electrochemical cell.
Ex: The deposition as PbO2 at a Pt anode and reduction of Cu2+ to Cu at a Pt cathode is of electrogravimetry.
When thermal or chemical energy is used to remove a volatile species, such method called as Volatilization gravimetry.
Ex: In determining the moisture content of bread, for example, we use thermal energy to vaporize the water in the sample.
Particulate gravimetry we determine the analyte by separating it from the sample’s matrix using a filtration or an extraction. The determination of total suspended solids is one example of particulate gravimetry.
A gravimetric precipitating agent should react specifically, and selectively with the analyte. The ideal precipitating reagent would react with the analyte to give a product that is
Readily filtered and washed free of contaminants
Low solubility so that no significant loss of the solid occurs during filtration and washing
Un-reactive with constituents of the atmosphere
Should not alter the composition after it is dried or, if necessary, ignited.

Fluid balance is an aspect of the homeostasis of body in which the amount of water in the body needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
The core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in; for example, in humans, the output (via respiration, perspiration, urination, defecation, and expectoration) must equal the input (via eating and drinking, or by parenteral intake).

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
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.

Interstitial fluid 12 – 15% of body weight
Plasma or Vascular fluid 4 – 5% of body weight
3. What are Electrolytes ?
• Substance when dissolved in solution it categorized into 2 type
• non electrolyte = do not separate into ions ( glucose / urea / creatinine)
• electrolyte = separates into ions & is able to carry an electrical current
• Cation - positively charged electrolyte e.g. Ca++
• Anion - negatively charged electrolyte e.g. Cl-
• No of Cations must equal to no of Anions for homeostasis to exist in each fluid compartment.
• Various organic and inorganic compounds are present in body fluids and concentration of them is
maintained in such a way that body cell and tissue have same environment.
4. • These three compartments are separated from each other by membranes that are permeable to
water and many organic and inorganic solutes.
• They are nearly impermeable to macromolecules such as proteins and are selectively permeable to
certain ions such as Na+, K+, Mg2+
• inorganic ions present in Body fluid
ANAION CATION
HCO3- Na+
Cl- K+
SO4- Ca+
HPO4- Mg2+
5. • There are a large number of products under the general heading of replacement therapy which can
be used by the physician when the body itself is unable to correct an electrolyte imbalance due to a
change in the composition of its fluids.
• These products include electrolytes, acids and bases, blood products, carbohydrates, amino acids and
proteins.
• Electrolytes are express in terms of mEq/L i.e. Milliequivalent per Liter rather than weight/volume
(w/v).

21. Electrolyte Used In Replacement Therapy
• In a healthy person, at least 70 liters of fluids are exchanged (secreted and reabsorbed) across the
walls of the intestines per day.
• The brain, heart, kidney, and virtually every other vital organ depend on these fluids to function.
• As the body takes in the water and salts it needs, it loses or excretes those it does not need through
urine, stools, and sweat.
• Thus, the secretion and absorption rates are kept in balance.
22. • In various condition like prolonged fever, sever vomiting or diarrhea creates a tremendous
outpouring of water (heavy loss of water) & electrolytes (body salts) state of dehydration and
impairs the capacity to reabsorb the fluid & electrolytes in our system.
• To compensate this loss, Electrolyte ReplacementTherapy / Oral RehydrationTherapy is required
• There are 2 type of solution used in replacement therapy.
1. Rapid replacement

33. Physiological Acid-Base Balance
• Electrolytes also play an important role in regulating body’s acid-base balance
• Body fluids contain balanced quantities of acids & bases.
• Acidity of the solution: No of [H+ ] present in fluid/solution - ECF
• Sources: [H+ ]
• Food
• Cellular metabolism of Glucose, Fatty acids, & Amino acids etc
• Reabsorption

Saliva 5.4 – 7.5
Bile 6.0 – 8.5
35. • Strong acid and base are continually taken and formed by body.
• pH of fluid inside and outside cell remain constant because of presence of buffer system.
• Most buffer in human body consist of weak acid and their salt.
• Function of buffer system is
• convert strong acid or base into weak acid or base.
• to prevent drastic change in pH of the blood.
36. • Major buffer of metabolic acid/base present in Plasma & Kidneys.
• Regulates blood Ph
• Some CO2, the end product of cellular metabolism, is carried to the lungs for elimination.
• Rest of dissolve in body fluid and form carbonic acid that dissociate to produce bicarbonate HCO3-
and hydronium H3O- ions.
37. Regulation of Blood pH
• The lung and kidney play important role in regulation of pH of blood.
• Lung regulate pH through retention or elimination of CO2 by changing rate and volume of ventilation
• The kidney regulate pH by excreting acid, primarily ammonia NH4- and by reclaiming HCO3- from
glomerular filtrate.
• In case of over breathing , excess excretion of CO2 occur, which leads to alkalosis.
• Kidney have ability to generate ammonia which neutralize acid product of protein metabolism
38. • Electrolyte also play important role in regulating acid base balance.
• It maintain by controlling H+ concentration of body fluid, particularly extracellular fluid.
• In healthy adult, pH of extracellular fluid remain 7.35 – 7.45
