A Rapid and Innovative Method for Prediction of Spin Multiplicity and Spin St...iosrjce
Determination of spin multiplicity is very important for identification of spin state of different
molecules or ions. But, the conventional method of prediction of spin multiplicity by using formula (2S+1) is
time consuming. So, in this manuscript, I tried to show a rapid and simple method for prediction of spin
multiplicity value without calculating the total spin quantum number(S=∑s). This method is only applicable for
homo and hetero nuclear diatomic molecules and ions having total electron (01-20).
This is my published paper in IOSR JAC novemboe 2015 edition in the field of inorganic chemictry.By this method we can easily find the spin multiplicity value of any diatomic molecules having total electron no 1-20 ,without calculation total spin quantum no.This is most easy way to calculate spin multiplicity value and also time saving method with simple concept.
Nuclear Decay - A Mathematical PerspectiveErik Faust
Radioactivity as a phenomenon is often misunderstood: if one says ‘Radioactive’, most people will think about disastrous electrical plants, dangerous bombs and other forms of life-threatening details. In my native Germany, members of the Green party have been campaigning for a decade to put an end to nuclear energy. Only few think of the useful aspects of this unique actuality, although radiotherapy is most promising of tools in the fight against cancer, and radioactive dating allows us to identify the age of any historical item. But even fewer people see radioactivity as the natural process that it actually is: A spontaneous mechanism, in which one nucleus decays into another. As an aspiring Physicist and Engineer, Radioactivity is one my favourite topics in the realm of science. I am fascinated at how we are able to predict exactly how many Nuclei will decay in a certain amount of time, but not say for certain which Nuclei exactly will do so.

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.

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
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
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.

2. To describe an isotope
To explain how atomic mass can vary within
one element
To calculate the abundance of different
isotopes
3. An element is usually defined by the number
of protons in the nucleus
If the number of protons changes the element
changes
The number of protons is equal to the
number of electrons in an atom
However the number of neutrons can change
between different atoms of the same element
4. An isotope is a chemical with a different
atomic mass but the same number of protons
as another
Take carbon as an example
5. The atomic mass of carbon on the periodic
table is 12.011
This is the mean mass of carbon on Earth
6. To calculate the abundance of one isotope it
is important to know the mass of all isotopes
and the mass on the periodic table
We are going to calculate the % abundance of
carbon 12
7. It is firstly important to understand the concept
of proportions and percentages
Carbon 12 + carbon 14 = 100% of all carbon
We are trying to find the % of 12C so we will call
that x
This means that:
12x + (100-x)14 / 100= 12.011
where x is % carbon 12,
(100-x) is % carbon 14
8. 12x + (100-x)14/100 = 12.011
Multiply out the brackets
12x + 1400-14x /100= 12.011
Multiply by 100 to remove the /100
12x +1400 -14x = 1201.1
Subtract the whole number leaving only x on one side
12x – 14x = -198.9
-2x=-198.9
-x = 99.45
x = 99.45
9. Research to find an element that has 2
common isotopes
Calculate the relative abundances of these 2
isotopes – If you find a website that offers
you the information ensure that it is the
correct answer!
Write out an exam style question and give it
to your neighbour
10. Average atomic mass =
(abundance of isotope 1)(mass of isotope 1) +
(abundance of isotope 2)(mass of isotope 2)
13. You will be given an element from the
periodic table
You will produce a short (3-4 minute)
presentation about that element
The presentation MUST include the electronic
structure, isotopes of the element, symbol
and position on the periodic table
It should also include uses of the element,
how it was discovered, impact of uses of the
element (if applicable)
14. The student explains how science is applied and
how it may be used to address a specific problem
or issue in a local or global context.
The student discusses the effectiveness of
science and its application in solving the problem
or issue.
The student discusses and evaluates the
implications of the use and application of science
interacting with at least two of the following
factors: moral, ethical, social, economic, political,
cultural and environmental.
15. The student uses sufficient scientific
language correctly.
The student communicates scientific
information effectively.
When appropriate to the task, the student
fully documents sources of information
correctly.
