BASAL METABOLIC RATE (BMR) and BASAL METABOLIC INDEX (BMI)
All energy is provided by three classes of nutrients: Macronutrients
Fats
Carbohydrates
Protein
Ethanol provide energy in some diets
Energy production can be measured
Heat output from the body
Amount of O2 consumed
It is calculated from the heat released by the total combustion of food in a calorimeter
It is expressed in kilocalories (kcal, or Cal)
The energy generated by metabolism is used for three energy-requiring processes:
Resting metabolic rate (RMR)
Physical activity
Thermic effect of food
Total Energy Expenditure (TEE): The number of calories expended by these processes in a 24-hour period

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

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.

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.
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.

Metabolism (2)
1.
2. Definition:
Chemical changes occur in the body.
1) Catabolic reactions:
* Definition: breakdown of large organic molecule with release of energy:
Protein (CHO or fat) CO2 + H2O + Energy. [ATP] used as:
a) Work energy. 25% used for essential functions.
b) Heat energy. 75%
2) Anabolic reactions:
Synthesis of organic large molecules with uptake of energy.
4. *Definition:
The rate of energy production [kcal] / unit time (on hour) /m2
surface area.
*Measured under 3 basal conditions:
1- Complete physical & mental rest:
for at least 1/2 an hour but without sleep as
sleep
decreases the BMR by 10%.
2- Post - absorptive state:
12-14 hours after the last meal to avoid specific
dynamic action (SDA).
3- In a comfortable external temperature:
Neither shivering nor sweating
5. also known as thermic effect of food (TEF)
or dietary induced thermogenesis (DIT), is the
amount of energy expenditure above
the basal metabolic rate due to the cost of
processing food for use and storage
6. The thermic effect of food is one of the
components of metabolism . A commonly
used estimate of the thermic effect of food is
about 10% of one's caloric intake, though the
effect varies substantially for different food
components. For example, dietary fat is very
easy to process and has very little thermic
effect, while protein is hard to process and
has a much larger thermic effect.
7. The thermic effect of food is the energy
required for digestion, absorption, and
disposal of ingested nutrients. Its magnitude
depends on the composition of the food
consumed:
Carbohydrates: 5 to 15% of the energy
consumed
Protein: 20 to 35%
Fats: at most 5 to 15%
8. Rate of energy input [food] = Rate of energy
output.
Accordingly:
1] If energy input > energy output :
+ve energy balance.
Increase the body weight.
2] If energy input < energy output :
-ve energy balance.
Decrease the body weight.
The adult basal level of caloric intake = 2000
kcal/day.
9. * Normal standard:
For adult man = 40 Kcal / hour / m2 ± 15%.
* Clinically: it is expressed as % deviation from normal standard:
E.g. if BMR = 60 Kcal /Hr/ m2. ……….Thus, it is + 50%.
* BMR is expressed per unit surface area and not per unit body
weight because
It is through the skin that most heat is lost to the atmosphere.
* It is the unavoidable cost of life:
I.e. metabolic activities of heart, respiratory muscles, liver,
muscle tone.
11. 1] Age:
Newly born infants = 25 KCal/h/m2
2- 5 years = 60 KCal/h/m2
Puberty = 55 KCal/h/m2
Adult = 40 KCal/h/m2 ±15%
Old age:1 Kcal decrease /10 years
2] Sex: BMR is decreased in female than male by 7% due to:
Greater fat stores [Fat has little metabolic activity].
3] Pregnancy and lactation: increase BMR due to:
++ Thyroid activity, & the added metabolism of the fetus.
4] Sleep: decrease BMR by 10% due to:
-- Muscle tone & --sympathetic activity.
5] Environmental temperature:
Cold shivering increase the MR maintains normal body temperature.
Hot increase the body temperature increase the MR.
6] Food: Increase the MR by the specific dynamic action.
7] Muscular exercise: Increase the MR.
12. Factors that increase MR:
1) Hyperthyroidism ++MR up to + 100% [except brain].
2) Hyperpituitarism:
a) ++ GH ++ MR.
b) ++ TSH ++ T4 ++ MR.
3) Hyperadrenalism: ++ catecholamines ++ MR.
4) Fevers: increase the body temperature ++ MR.
5) Heart failure due to ++ activity of respiratory muscles to
fight dyspnea.
6) Blood diseases: as polycythemia - the hematocrit (the volume
percentage of red blood cells in the blood) is elevated- due to
over activity of bone marrow.
13. increase in the number of red blood
cells ("absolute polycythemia") or
decrease in the volume of plasma ("relative
polycythemia").
14. 1) Hypothyroidism: --MR by 40% of the normal.
2) Hypopituitarism: due to atrophy of endocrine
glands.
3) Hypothermia:
-- body temperature by 1oC--MR by 13%.
4) Under-nutrition: due to -- energy producing cell
nutrients.
5) Hypo-function of adrenal cortex: due to --
corticoids.
15. Factors regulating the activity of appestate center:
1) Psychological conditions:
Vision, smell of food affect centers in limbic lobe.
2) Receptors in the mouth & esophagus:
Monitoring food intake.
3) Stomach distension: stop of feeding.
4) GIT hormones and insulin: stimulate satiety center.
5) The blood levels of glucose, amino acids, fatty acids &
glycerol affect hypothalamus.
6) SDA of food ++body temperature inhibition of food
intake.
7) Cold environment ++ food intake.
N.B Satiety center and appetite center are located in the
hypothalamus
16. a) The lipostatic hypothesis:
* Adipose tissue:
Humoral signal [proportionate to the amount of fat].
Acts on the hypothalamus --food intake &++energy
output.
b) The gut peptide hypothesis:
* Food in the GIT secrete GIT polypeptides.
Acts on the hypothalamus --food
intake.
c) The glucostatic hypothesis:
* Glucose utilization in the hypothalamus sensation of
satiety.
d) The thermostatic hypothesis:
* --Body temperature ++ appetite.
* ++Body temperature -- appetite.

Editor's Notes
الانسان لا يستخدم ال 25% كلها و لكن بيستخدم مثلا 17 ال 18 % فقط و لما لاعبين الكرة بياخدوا منشطات دا علشان يحاولوا يوصلوا الى 25 %
ال 75% بيضيعوا او حايا بيقولوا انهم بيستخدموا مع بعض الانزيمات و التفاعلات
Satiety center and appetite center are located in the hypothalamus
ملحوظة هامة وجود انسولين كتير معناه ان الشخص واكل كتير فحصل افراز كتير للانسولين فيعدى فى الدم على مراكز الشبع فى المخ فيشعر ان الانسولين كتير اذن واكل
Lipostatic hypothesis المخ بيعمل monitor لل free fatty acids (ffa)اللى فى ال blood و احنا عارفين ان ال ffa بيجى من ال fat metabolism فلو ال brain شاف ان ال ffa قليلة اذن الfat metabolism كان قليل اذن الشخص دا شيعان علشان كدا مش بيحرق ال fat ودا ب يعمل stimulation لل satity center و اذا كان ال ffa عالية يبقى ال fat metabolism كانت عالية يبقى بيكسر fat كتير و دا معناه ان هو مش بياكل اذن فهو جعان و ال brain بيعمل inhibition لل satiety center و يخليه يحس بالجوع hunger علشان ياكل
باقى النظريات التلاتة التانين بتعتمد على ان satiety center فى ال hypothalumusلما بتحس ان الحاجة موجودة فى الدم بتخليه يحس انه شبعان و مياكلش لكن لما الحاجة مبتبقاش موجودة ال center بتحس انها مش موجودة و بتخليه يحس بالجوع و ياكل
