Lewis diagrams represent the valence electrons of atoms and are used to show covalent bonding between atoms. Covalent bonds form through the sharing of valence electrons. The octet rule states that atoms want eight electrons in their outer shell and will share electrons to reach eight, except for hydrogen which is stable with two. Lewis structures show the outer shell electrons that participate in bond formation.
The attractive force which holds various constituents (atom, ions, etc.) together and stabilizes them by the overall loss of energy is known as chemical bonding. Therefore, it can be understood that chemical compounds are reliant on the strength of the chemical bonds between its constituents; The stronger the bonding between the constituents, the more stable the resulting compound would be.

Nucleosynthesis is the process of creating new at.pdfinfo54093
Nucleosynthesis is the process of creating new atomic nuclei from pre-existing
nucleons (protons and neutrons). The first nuclei were formed about three minutes after the Big
Bang, through the process of Big Bang nucleosynthesis. With the formation of stars, heavier
nuclei were created through stellar nucleosynthesis, a process that has continued to the present.
Supernova nucleosynthesis and cosmic ray spallation are also significant sources of nuclei. In
addition to these major processes in space, many minor natural processes continue to produce
small amounts of new elements on Earth. These nuclides are naturally produced on a continuing
basis via the decay of long-lived primordial radionuclides (via radiogenesis), from natural
nuclear reactions in cosmic ray bombardment of elements on Earth (cosmogenic nuclides), and
from other natural nuclear reactions powered by particles from radioactive decay, (producing
nucleogenic nuclides). In modern theory, there are a number of astrophysical processes which
are believed to be responsible for nucleosynthesis in the universe. The majority of these occur
within the hot matter inside stars. The successive nuclear fusion processes which occur inside
stars are known as hydrogen burning (via the proton-proton chain or the CNO cycle), helium
burning, carbon burning, neon burning, oxygen burning and silicon burning. These processes are
able to create elements up to iron and nickel, the region of the isotopes having the highest
binding energy per nucleon. Heavier elements can be assembled within stars by a neutron
capture process known as the s process or in explosive environments, such as supernovae, by a
number of processes. Some of the more important of these include the r process, which involves
rapid neutron captures, the rp process, which involves rapid proton captures, and the p process
(sometimes known as the gamma process), which involves photodisintegration of existing nuclei.

the use of social media and any extras like airport upgrades.
Legacy carriers American, Delta, and United are often viewed as the dinosaurs of the industry.
They are saddled with huge operating costs and fleets that have different types of aircrafts, which
means they are slower to implement changes.
But changes are happening. All three (Delta especially) are aggressively upgrading their planes
with Wi-Fi, advanced video-on-demand systems, streaming content, and power outlets, as well
as improved Web and app experiences. United, for example, recently announced Wi-Fi and
personal device entertainment will be installed in its fleet of regional jets. Implementation is a bit
haphazard (you never really know which plane actually has Wi-Fi, for example), and rollout will
last into next year (and beyond), but the legacy carriers definitely deserve some praise, after
years of declining service.

Ion Selective Electrodes (ISE) are membrane electrodes that respond .pdfinfo54093
Ion Selective Electrodes (ISE) are membrane electrodes that respond selectively to ions in the
presence of others. These include probes that measure specific ions and gases in solution. The
most commonly used ISE is the pH probe.
An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a transducer (or
sensor) that converts the activity of a specific ion dissolved in a solution into an electrical
potential, which can be measured by a voltmeter or pH meter.
Other ions that can be measured include fluoride, bromide, cadmium, and gases in solution such
as ammonia, carbon dioxide, and nitrogen oxide.
The use of Ion Selective Electrodes in environmental analysis offer several advantages over
other methods of analysis. First, the cost of initial setup to make analysis is relatively low. The
basic ISE setup includes a meter (capable of reading millivolts), a probe (selective for each
analyte of interest), and various consumables used for pH or ionic strength adjustments.
Glass Ion-Selective Electrodes
The first commercial glass electrodes were manufactured using Corning 015, a glass with a
composition that is approximately 22% Na2O, 6% CaO and 72% SiO2. When immersed in an
aqueous solution for several hours, the outer approximately 10 nm of the membrane’s surface
becomes hydrated, resulting in the formation of negatively charged sites, —SiO–. Sodium ions,
Na+, serve as counter ions.
Solid-State Ion-Selective Electrodes
A solid-state ion-selective electrode uses a membrane consisting of either a polycrystalline
inorganic salt or a single crystal of an inorganic salt. We can fashion a polycrystalline solid-state
ion-selective electrode by sealing a 1–2 mm thick pellet of Ag2S—or a mixture of Ag2S and a
second silver salt or another metal sulfide—into the end of a nonconducting plastic cylinder,
filling the cylinder with an internal solution containing the analyte, and placing a reference
electrode into the internal solution.
Liquid-Based Ion-Selective Electrodes
Another class of ion-selective electrodes uses a hydrophobic membrane containing a liquid
organic complexing agent that reacts selectively with the analyte. Three types of organic
complexing agents have been used: cation exchangers, anion exchangers, and neutral ionophores.
A membrane potential exists if the analyte’s activity is different on the two sides of the
membrane. Current is carried through the membrane by the analyte.

Hubs and switches connect computers to create a LAN.HubA Hub co.pdfinfo54093
Hubs and switches connect computers to create a LAN.
Hub:
A Hub connects multiple computers together in a Local Area Network (LAN). All information
sent to the hub is then sent through each port to every device in the network.
When a hub receives a packet at one of its ports from a PC on the network, it transmits the
packet to all of its ports and, thus, to all of the other PCs on the network. This mean bandwidth
was wasted because all traffic was sent to all ports.
If two or more PCs on the network try to send packets at the same time then a collision occur.
When that happens all of the PCs have to retransmit with different time to resolve the conflict.
The process is prescribed in the Ethernet Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) protocol.
Switch:
A switch is used to connect various network segments. In telecommunications, a switch is a
network device that selects a path or circuit for sending a unit of data to its next destination. A
switch may also include the function of the router, a device or program that can determine the
route and specifically what adjacent network point the data should be sent to. In general, a switch
is a simpler and faster mechanism than a router, which requires knowledge about the network
and how to determine the route. In networks, a device that filters and forwards packets between
LAN segments. Switches operate at the data link layer and sometimes the network layer of the
OSI Reference Model and therefore support any packet protocol. LANs that use switches to join
segments are called switched LAN.
The main difference between Switch and Hub is, A switch is effectively a higher-performance
alternative to a hub. People tend to benefit from a switch over a hub if their home network has
four or more computers, or if they want to use their home network for applications that generate
significant amounts of network traffic, like multiplayer games or heavy music file sharing.
Hubs operate using a broadcast model and switches operate using a virtual circuit model. When
four computers are connected to a hub, for example, and two of those computers communicate
with each other, hubs simply pass through all network traffic to each of the four computers.
Switches, on the other hand, are capable of determining the destination of each individual traffic
element and selectively forwarding data to the one computer that actually needs it. By generating
less network traffic in delivering messages, a switch performs better than a hub on busy
networks.

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.

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

Lewis diagrams, also called electron-dot diagrams.pdf
1. Lewis diagrams, also called electron-dot diagrams, are used to represent paired and
unpaired valence (outer shell) electrons in an atom The Lewis structure is used to represent the
covalent bonding of a molecule or ion. Covalent bonds are a type of chemical bonding formed by
the sharing of electrons in the valence shells of the atoms. Covalent bonds are stronger than the
electrostatic interactions of ionic bonds, but keep in mind that we are not considering ionic
compounds as we go through this chapter. Most bonding is not purely covalent, but is polar
covalent (unequal sharing) based on electronegativity differences. The atoms in a Lewis
structure tend to share electrons so that each atom has eight electrons (the octet rule). The octet
rule states that an atom in a molecule will be stable when there are eight electrons in its outer
shell (with the exception of hydrogen, in which the outer shell is satisfied with two electrons).
Lewis structures display the electrons of the outer shells because these are the ones that
participate in making chemical bonds.
