Timber is a renewable building material which has been in use since early ages. Timber needs to be used in the way which minimizes the wastage, because when we cut a tree, it has massive negative impact to the environment. So, when look from this point of view, it is better to reduce usage of timber. But when consider materials for structural elements, substitutes for timber such as concrete, steel, fiber glass, plastic, glass, etc., effect to the environment after demolishing structures which are built from these substitutes is huge which is not done by timber. Therefore, use of timber effectively in construction industry has become a timely need.
Lot of research has been carried out to gain the maximum output from timber. From that lot of products have been made. As an example, use of composite timber products, built up sections can be identified. Most architects tend to use timber in their designs mainly to give the structure an esthetically pleasing output.

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

Embracing GenAI - A Strategic ImperativePeter 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.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
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.

4. Converting logs
Horizontal bandsaw
Reasons to convert timber
Allows wood to dry faster
Provides wood of usable
size and shape
Allows the quality of the
timber to be seen
6. Advantages
– Low cost and fast
– Maximum width of planks obtained from log.
– Little wastage.
– Reveals attractive grain pattern, especially in
softwoods.
Disadvantages
– Not suitable for structural timber
– Some boards are all sapwood
– With this method cupping caused by tangential
shrinkage is a problem (cupping is the warping
of the plank away from the heart of the tree)
8. Advantages
– An attractive grain pattern
is produced
– Boards are more stable
and shrink less
– Boards wear more
evenly,important for
flooring
Disadvantage
– Expensive, as the log has
to be first quartered then
turned for every cut.
– Because the log is
quartered then cut again
narrower boards are
produced
10. Advantages
– Produce board with flame
figure
– Tangential boards are
strong boards, used for
beams and joists
– Heartwood and sapwood
are easily separated
– These boards can take a
nail without splitting
because of the position of
their annual rings
Disadvantages
– Prone to shrinkage
(Cupping)
– It is expensive as the log is
turned 90º for each cut
11. Exam question
1
Shown in the diagram are two methods for timber conversion.
(a)
(b)
(c)
Name the two methods of conversion shown in the diagrams.
State two advantages and two disadvantages of each method.
The diagrams show the ends of two boards, M and N. Which of
the boards is most likely to cup? Give a reason for your answer.
Describe, using a neat freehand sketch, the direction of cupping.
(JC, HL, 2005)
12. Sample answer to exam question
1 (a) The methods of conversion shown are:
A Through and through sawing, also called slash or plain sawing.
B Quarter sawing or radial sawing.
(b) Through and through sawing
Advantages
•
•
•
There is very little waste from this method
It gives wide boards
It is a cheap and easy method
Disadvantages
•
•
•
The boards are prone to cupping
The boards have no particular grain pattern
There would be a lot of sapwood in many boards so more likely
to rot due to fungi and insects
13. Sample answer to exam question
1 (b) Quarter sawing
Advantages
• The boards are stable
• The boards are hard-wearing and used in flooring
Disadvantages
• More labour required, as the logs need to be turned
• More expensive
• More waste produced
14. Sample answer to exam question
1 (c) The board most likely to cup is board M. This is because when
the wood begins to dry, the cells shrink.
The shrinkage occurs along the rings, which tends to pull the
board into a curved shape as a result.
The other board, N, will have more even shrinkage because of
the arrangement of the rings as shown.
