The recently enacted Jumpstart Our Business Startups (JOBS) Act contained a provision directing the Securities and Exchange Commission to amend Regulation D to remove the ban on general solicitation and advertising of private offerings. This change will allow alternative investment managers and others conducting private offerings to have increased legal certainty when communicating with investors and the general public, which will enable these managers to share more information and promote greater understanding of the industry. Amending Regulation D will not change the type of investor – institutions and high net-worth individuals – able to buy into a private offering, but it will lead to more transparency in the alternative investment industry.

WOOD FOR CIVIL ENGINEERING STUDENTS IN CONSTRUCTIONelviraandadi14
Wood is one of the most important raw material not only because it is used literally for hundreds of products, but also because it is a renewable natural resource.
Wood is a hygroscopic and anisotropic cellular material of biological origin.
Hygroscopic means it has the ability to attract moisture from air.
Anisotropic means that its structure and properties vary in different directions.
the shade of the wooden designs is white with a pinkish or yellowish tinge. the core rays are slim, vary satisfactory within the radial segment. the once a year layers differ badly. timber within reason hard, homogeneous in density, nicely processed. it has a extraordinary resistance to splitting, easily lends itself to imitation of valuable rocks, is well coloured and polished, soaked with antiseptics. birch wood is prone to warping and rot. the maximum treasured for the manufacture of parquet is the Karelian birch, which has a particularly cute texture and color.

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 Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
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.

PHYSICAL PROPERTIES OF WOOD THAT AFFECT ADHESIVE
BONDING.
Density or Specific Gravity (SG)
Density or specific gravity is one of the most important physical properties of wood.
Density is the mass or weight of wood divided by the volume of the specimen at the
given moisture content. Thus unit for density arekg/m3
or lb/ka3
. In hardwood, density
is depending not only on fibre wall thickness but also on amount of void space
occupied by vessel and parenchyma.
The glue-bond quality required for the species listed and for other species falling
within the density range given the solid wood substances of all species has about same
specific gravity, but in high-density species less of the volume in capillary structure of
dry wood is occupied by air. As moisture is added to the wood, the air space
decreases. When wood of different species is examined with the naked eye, the ratio
of wood substances to air species not readily seen.
Wood pores and vessel
Different wood species may influence the bondlines of adhesives. The porosity and
the pore size distribution were analysed as a function of the respective position. The
pores will completely bind together if the neighbouring pores during adhesion have
bigger spaces or large diameter sizes of pores or vessel. The penetration of the
adhesive to the adherence which have larger diameter of pores may conclude the
strength of wood bonding. It is also can be explained in easy words by; before the
adhesive turn to solid, it is in liquid form and travel along the pores and adhesive may
penetrate easily in form of size of pores.
Less, medium or more pores with small sizes may affect the bonding strength between
the adhesive with the adherence. Small sizes of pore which evenly appear in
adherence may conclude the good result in bonding strength in adhesion. It can be
explain when the adhesive penetrate in the pores or vessel evenly its will grip the
whole surface of adherence during the process.
Grain and texture
The term ofgrain and texture are commonly used rather loosely in connection with
wood. Grain is often used in reference to the relative sizes and distributions of cells,
as is fine grain and coarse grain; this use of grain is roughly synonymous with texture.
Grain is also used to indicate the orientation of the cells of axial system (fibre
direction), as in “along the grain”, straight grain, spiral grain and interlocked grain.
10. 10
The texture of wood by different direction may influence the bonding strength in
adherence. Two term of direction; along the grain and against the grain. Many light
hardwoods may be easily to cut by against the grain compared to the heavy or
medium hardwood. The explanationmaybe same as the sizes of pores but the shape of
grain may conclude the dissimilar of bonding result.
11. 11
DISCUSSION
The difference species will affect the bonding strength when using adhesive because for each
type of wood has a different characteristic based on their density, texture of surface, porous
and others.
For the heavy hardwood species, merbau has air dry density from 515-1040 kg/m3
(32-65 lb/ka3
) meanwhile the red balau has 800-850 kg/m3
(50-55 lb/ka3
). This is classifying
as high density woods. The medium hardwood species, Kulim (Scorodocarpus borneensis)
has range density from 835 kg/m3
(52 lb/ka3
) meanwhile Mata ulat (Kokoona coriacea) has
880-1040 kg/m3
(55-65 lb/ka3
). This is classify as moderate density woods and for the light
hardwood species, Jelutong ( Dyera costulata) has range density from 415-495 kg/m3
(26-31
lb/ka3
) and Pulai ( Alstonia angustiloba) has range from 464 kg/m3
(29 lb/ka3
). This is
classifying as low density woods.
The high density woods have thick walls and small lumen volumes, whereas low
density woods have thin walls with large lumen volumes. The strength of wood is directly
related to its density because thick-walled cells are capable of withstanding much greater
stress than are thin-walled cells.High density woods are difficult to bond for several reasons.
Because of thicker cell walls and less lumen volume, adhesives do not penetrate easily, so
important mechanical interlocking of adhesives is limited to one or two cells deep. Much
greater pressure is required to compress stronger, stiffer, high density wood to bring contact
between wood surface and adhesive.
Texture and grain may influence the bonding strength of the adhesion. Based on the
observation of the different species, the level of coarseness of wood may influence the
bonding strength. On the other words, if the wood is very coarse surface it may help in the
bonding strength in adhesion. The adhesive may not easily shear during gel time because of
the coarseness of the wood would grip the entire surface which spread by adhesive. It is
different to the smooth surface wood which is tending to shear or sliding easily during gel
time.
Size of pores and vessel and number of pores appear in wood may also affect the
bonding strength of the adhesion. Inference for the size of pores; the larger pores appear in
wood more high strength of adhesive bind the adherence together. The liquid form of
adhesive are allow travel along the pores and adhesive may penetrate easily in form of size of
pores. Besides, the number pores appear in wood also affect the entire bonding strength of
adhesion. Many pores appear could result high strength of wood bind process.
