Semiconductor Hubs for Research & InnovationZinnov
The semiconductor industry has evolved significantly in the last 50 years. While in early 60s, US was the clear market leader, by the 90s the semiconductor industry in Taiwan, Singapore and Korea posed a competitive threat to that in the US. Recent times have witnessed other locations in China and India establish themselves firmly on the global semiconductor landscape.
For any innovation hub, the entire ecosystem has to be favorable for growth. This includes access to large skilled talent pool, strong university ecosystem, favorable government policies etc.

Tremendous value lies in how organizations leverage ecosystems to deliver outcomes and solutions through platforms. Some pioneering communications, media and technology companies are already evaluating how they can participate in existing ecosystems. A few are even pursuing more valuable ecosystem leadership roles.
The good news is that companies don't need to build platforms to compete in the platform economy. But they must begin to stake their claim now with three key actions, or risk being marginalized.

Define ecology, biogeography, ecosystem, and the community. Explain .pdfsanuoptical
Define ecology, biogeography, ecosystem, and the community. Explain photosynthesis and
respiration, and derive net photosynthesis and the world pattern of net primary productivity.
Relate abiotic ecosystem components to ecosystem operations, and explain trophic relationships.
Solution
Ecology :-The prefix \'eco\' has become synonymous with environmentally-friendly living. This
green fad, however, has more to do with conservation biology than with ecology, where the
prefix is borrowed from.All organisms, no matter their size, their species, or where they live,
need to interact with other organisms in their \'neighborhood\' and with their environment in
order to survive.Ecologyis the scientific study of the interactions between organisms and their
environment. The term comes from the Greek \'study of house\', or the study of the place we live
in.The scope of ecology is huge, and it encompasses all organisms living on Earth andtheir
physical and chemical surroundings. For this reason, the field is usually divided into different
levels of study including: organismal ecology, population ecology, community ecology and
ecosystem ecology.
Biogeography:-Biogeography is broken into two subcategories:*.Phytogeography, the study of
how plants are distributed on the earth*.
Zoogeography, the study of how animals are distributed on the earth (including
bacteria)Biogeography is very important in understanding how animals and plants have changed
the landscape over time. This field utilizes knowledge from the study of rocks or geology, the
study of ecosystems or ecology, and the study of the physical planet or physical geography to
answer questions about how organisms react to changes in their environment.
Ecosystem:-An ecosystem includes all of the living things(plants, animals and organisms) in a
given area, interacting with each other, and also with their non-living environments (weather,
earth, sun, soil, climate, atmosphere).
Photosynthesis:-Photosynthesis is the process used by plants, algae and certain bacteria to
harness energy from sunlight into chemical energy.There are two types of photosynthetic
processes: oxygenic photosynthesis and anoxygenic photosynthesis. Oxygenic photosynthesis is
the most common and is seenin plants, algae and cyanobacteria.undefined During oxygenic
photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2),
which produces carbohydrates. In this transfer, the CO2 is \"reduced,\" or receives electrons, and
the water becomes \"oxidized,\" or loses electrons. Ultimately, oxygen is produced along with
carbohydrates.
Respiration:-It may be associated with:*.breathing, which is the process of inhaling and exhaling
gases from and into theexternal environment– a function of the lungs and other structures with
similar function (e.g.gills)*.cellular respiration, which is the process utilized by cells to obtain
energy from theoxidationoforganic compoundsaccompanied by the consumption ofoxygen(when
availa.
the purpose of this presentation was to know that the Ecosystem is a natural cycle, it makes the balance of nature. In which, Human being are integral part of ecological systems and depend on nature for survival and quality of life.
So we have the duty to save nature, to survive ecosystem, and to safe ourselves.
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.
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.
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.

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.
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.

2. What Is
Ecosystem
An ecosystem is a community
of living organisms (plants,
animals and microbes) in
conjunction with the nonliving
components of their environment
(things like air, water and
mineral soil), interacting as a
system.
3. Niche v/s habitat
Habitat:
The natural home or
environment of an animal,
plant, or other organism.
Niche:
A role taken by a type of
organism within its
community.
4.
5. Biotic Factors
Biotic components
These are the living things that shape an ecosystem.
A biotic factor is any living component that affects another organisms,
including animals that consume the organism in question, and the living food that the
organism consumes.
Example :
a fresh water
ecosystem
showing prey
and a predator
6. More About Biotic
Components
Biotic components are contrasted to abiotic components, which are non-living
components of an organism's environment, such as temperature,
light, moisture, air currents, etc. Biotic components usually include:
7. Abiotic factors
In biology and ecology, abiotic components include physical conditions and non-living
resources that affect living organisms in terms of growth, maintenance,
and reproduction. Resources are distinguished as substances or objects in the
environment required by one organism and consumed or otherwise made unavailable
for use by other organisms.
Component degradation of a substance by chemical or physical processes,
e.g. hydrolysis. All non-living components of an ecosystem is called abiotic
components.

13. ENERGY FLOW
Food chain
A linear sequence of links in a food web starting from species that are called
producers in the web and ends at species that are called decomposers in the web. A
food chain also shows how the organisms are related with each other by the food
they eat. A food chain differs from a food web, because the
complex polyphagous network of feeding relations are aggregated into tropic species
and the chain only follows linear monophagous pathways.
14. Types of food chain

16. Ecological succession
Ecological
succession is the
observed process of
change in
the species structu
re of an ecological
community over time.
The time scale can
be decades (for
example, after a
wildfire), or even
17. Primary succession is one of two types of
biological and ecological succession of plant
life, occurring in an environment in which new
substrate devoid of vegetation and usually
lacking soil, such as a lava flow or area left
from retreated glacier, is deposited.
18.
19. Secondary succession is one of the two types
of ecological succession of plant life. As opposed to
the first, primary succession, secondary succession is
a process started by an event that reduces an already
established ecosystem to a smaller population of
species.

24. Phosphorus cycle
The phosphorus cycle is the biogeochemical cycle that describes the
movement of phosphorus through the lithosphere, hydrosphere,
and biosphere. Unlike many other biogeochemical cycles,
the atmosphere does not play a significant role in the movement of
phosphorus, because phosphorus and phosphorus-based compounds are
usually solids at the typical ranges of temperature and pressure found on
Earth. The production of phosphine gas occurs only in specialized, local
conditions.
On the land, phosphorus (chemical symbol, P) gradually becomes less
available to plants over thousands of years, because it is slowly lost in
runoff. Low concentration of P in soils reduces plant growth, and slows soil
microbial growth - as shown in studies of soil microbial biomass
