The plasma membrane is made of phospholipids. A phospholipid molecule has a polar head and two non-polar tails. How does the plasma membrane work? Polar molecules can interact with the polar heads and cross the membrane. Polar molecules form covalent bands with the polar heads and become permanently attached to them. Polar molecules are excluded from the interior of the membrane by repulsion from non-polar tails: Non polar molecules are excluded from the interior of the membrane by repulsion from non-polar tails. Non-polar molecules are attracted to the non- polar tails, thus not being able to cross the membrane..

The social media app you are designing a database for allows Users to.pdf
The social media app you are designing a database for allows Users to share two kinds of
content: **Messages** and **Stories**.
Tables structure
Decide what fields and data types are necessary for the two tables necessary for this app: `users`
and `posts`. The `posts` table stores both Messages and Stories.
Bear in mind that the application must be able to use these tables to perform the required
functionality outlined below.
Users:
Users can register for the app by supplying their...
- email
- password
- handle (i.e. username).
Messages:
- Messages consist of text only.
- Messages are sent from one user to another specific user.
- Messages become invisible immediately after view and don't show up in the app thereafter.
- Messages are never actually deleted from the database table, even when invisible to the user
(the social media company that produces the app keeps 'deleted' content in its database for future
data harvesting, monetization purposes, and more.)
Stories:
- Stories consist of text only.
- Stories are public and every user can see them.
- Stories become invisible 24 hours after posting and don't show up in the app thereafter.
- Stories are never deleted from the database table, even when invisible to the user.
Write the SQL command to create these tables with the structure you determine is necessary.
### Practice data
Insert realistic-looking dummy data for one thousand Users, one thousand Messages, and one
thousand Stories.
Include the practice data in CSV files named `users.csv` and `posts.csv` in the directory named
`data`.
Write the SQLite commands necessary to import the data into the respective tables.
### Queries
Write a single SQL query to perform each of the followin tasks:
1. Register a new User.
1. Create a new Message sent by a particular User to a particular User (pick any two Users for
example).
1. Create a new Story by a particular User (pick any User for example).
1. Show the 10 most recent visible Messages and Stories, in order of recency.
1. Show the 10 most recent visible Messages sent by a particular User to a particular User (pick
any two Users for example), in order of recency.
1. Make all Stories that are more than 24 hours old invisible.
1. Show all invisible Messages and Stories, in order of recency.
1. Show the number of posts by each User.
1. Show the post text and email address of all posts and the User who made them within the last
24 hours.
1. Show the email addresses of all Users who have not posted anything yet.
### Hint
The following SQLite code returns the difference in hours between the time now and an earlier
date and time - this may be useful in determining the number of hours that have passed since a
post was made: `ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21 12:50:00')) * 24)`
To see the return value of this command directly (not as part of a comparison operation), use the
following syntax: `SELECT ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21
12:50:00')) * 24);`

The Saint Lucia Blood Bank- a private charity partly supported by gove.pdf
The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located
on the Caribbean island of Saint Lucia. The blood bank has just finished its operations for
September, which was a very busy month due to a powerful hurricane that hit neighboring
islands causing many injuries. The hurricane largely bypassed Saint Lucia, but residents of Saint
Lucia willingly donated their blood to help people on other islands. As a consequence, the blood
bank collected and processed over 20% more blood than had been originally planned for the
month. A report prepared by a government official comparing actual costs to budgeted costs for
the blood bank appears below. Continued support from the government depends on the blood
bank's ability to demonstrate control over its costs. The managing director of the blood bank was
very unhappy with this report, claiming that his costs were higher than expected due to the
emergency on the neighboring islands. He also pointed out that the additional costs had been
fully covered by payments from grateful recipients on the other islands. The government official
who prepared the report countered that all of the figures had been submitted by the blood bank to
the government; he was just pointing out that actual costs were a lot higher than promised in the
budget. The following cost formulas were used to construct the planning budget: Required:
1.Complete the flexible budget performance report for September. (Indicate the effect of each
variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero

date and time - this may be useful in determining the number of hours that have passed since a
post was made: `ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21 12:50:00')) * 24)`
To see the return value of this command directly (not as part of a comparison operation), use the
following syntax: `SELECT ROUND((JULIANDAY('now') - JULIANDAY('2021-02-21
12:50:00')) * 24);`

The Saint Lucia Blood Bank- a private charity partly supported by gove.pdf
The Saint Lucia Blood Bank, a private charity partly supported by government grants, is located
on the Caribbean island of Saint Lucia. The blood bank has just finished its operations for
September, which was a very busy month due to a powerful hurricane that hit neighboring
islands causing many injuries. The hurricane largely bypassed Saint Lucia, but residents of Saint
Lucia willingly donated their blood to help people on other islands. As a consequence, the blood
bank collected and processed over 20% more blood than had been originally planned for the
month. A report prepared by a government official comparing actual costs to budgeted costs for
the blood bank appears below. Continued support from the government depends on the blood
bank's ability to demonstrate control over its costs. The managing director of the blood bank was
very unhappy with this report, claiming that his costs were higher than expected due to the
emergency on the neighboring islands. He also pointed out that the additional costs had been
fully covered by payments from grateful recipients on the other islands. The government official
who prepared the report countered that all of the figures had been submitted by the blood bank to
the government; he was just pointing out that actual costs were a lot higher than promised in the
budget. The following cost formulas were used to construct the planning budget: Required:
1.Complete the flexible budget performance report for September. (Indicate the effect of each
variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero
variance). Input all amounts as positive values.).

The reason why Copernicus's heliocentric theory eventually came to be regarded as preferable to
the geocentric theory of Ptolemy is that the heliocentric theory accounted for the same observed

The French Revolution Class 9 Study Material pdf free download
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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
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 ...
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.
Embracing GenAI - A Strategic Imperative
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 plasma membrane is made of phospholipids- A phospholipid molecule.pdf
- 1. The plasma membrane is made of phospholipids. A phospholipid molecule has a polar head and two non-polar tails. How does the plasma membrane work? Polar molecules can interact with the polar heads and cross the membrane. Polar molecules form covalent bands with the polar heads and become permanently attached to them. Polar molecules are excluded from the interior of the membrane by repulsion from non-polar tails: Non polar molecules are excluded from the interior of the membrane by repulsion from non-polar tails. Non-polar molecules are attracted to the non- polar tails, thus not being able to cross the membrane.
