Soil is formed through the decomposition of organic matter and rocks, weathering and erosion, and is made up of minerals, organic matter, water, and air. It exists in layers called horizons or profiles and can be sandy, clay, or loam soil depending on particle size, each with different abilities to retain air and water that plants need. Loam soil, with a mix of particle sizes, provides the best environment for plant growth by allowing both air and water in the soil.
Covers information on soil formation, soil characteristics, soil food webs, globals soil maps, and ESTAR satellite data and a link to NCRS GIS soil database
Soils are characterised by several physical properties. The important ones are: (1) Soil separates and texture,
(2) Structure of soil, (3) Weight and soil density, (4) Porosity of soil, (5) Permeability of soil, (6) Soil colour, (7) Temperature of soil, and (8) Soil Plasticity, Compressibility and Erodibility. Some of these are discussed in this module.

Many people and leaders confuse the mental states of obligation and responsibility.
Obligation is the mindset of “have to, don’t want to.” In this state one’s performance is barely adequate to get a pass. One resents the trap they are in and demonstrates resistance.
Responsibility is the mindset of self-empowerment. One feels they are freely choosing their life and work. High performance follows, as does happiness.
As a leader…
Notice your feelings of obligation about your life and work, and the impact to performance and happiness.
What do your charges learn when you demonstrate obligation, i.e., “I have no choice. I have to”?
How can you lead from and demonstrate responsibility and nurture your charge’s experience of responsibility?

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.
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.

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.
2. What is Soil made of?
Soil is made of:
1) mineral particles
2) organic matter
3) water
4) air
3. The Organic Matter in Soil
is Mostly Humus
When insects, worms, bacteria, and fungi and other
organisms die they decay and form a material called
“humus”.
As more organisms die, the soil becomes more fertile.
4. Why is Soil Important?
Much of the life on earth depends on soil
Soil is just as important as water, air, and sunlight.
– Without soil, there would be no plants.
– Without plants, there would be no food, shelter or
oxygen to breathe for humans or animals.
Soil provides the
nutrients needed by
most plants to grow.
5. How are Soils Formed?
1. Decomposition –
animals and plants
die and “feed” the
soil
6. How are Soils Formed?
1. Decomposition
2. Weathering (not
moving)– rain and
wind break rocks
down into soil
7. How are Soils Formed?
1. Decomposition
2. Weathering
3. Erosion (moving)–
when the rocks
break and fall apart
in the wind or rain
10. Types of Soil
Three Types:
1) Sandy soil contains large particles. Sandy
soils stay loose and allow moisture to
penetrate easily, but do not retain it for long
term use.
2) Loam soil is a mix of sand, silt or clay, and
organic matter. Loam soils are loose and look
rich.
3) Clay soils are made of very small particles.
They feel slick and sticky when wet.
11. Clay Soil is Slippery and Holds Water Up
Remember, the
particles in clay
soil are very small
12. Sandy Soil does NOT Hold Water
Sandy soil has
large particles and
holds air but not
water
13. Loam Soil holds both Air AND Water
Loam soil has
both large and
small particles an
holds water and
air well
15. What do Plants Need to Grow?
1. Air
2. Water
3. Nutrients Soil responsible for these 3
4. Sunlight
So, if soil does not have a lot of air, plants won’t grow well.
This is why clay soils are bad for plant growth.
If soil does not have a lot of water, plants won’t grow well.
This is why sandy soils are bad for plant growth.
Loam soils can hold water and air, and are the best for
plant growth.
