Carbon plays a central role in living organisms because it can combine in many ways with itself and other elements like hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Living things are made up of molecules consisting largely of these elements. Carbon forms the backbone of these molecules, allowing them to link together into the large and complex molecules that make up structures and carry out functions in organisms. Examples of large molecules found in living things include DNA, proteins, carbohydrates, and fats, while small molecules include water and salt.

The document discusses photosynthesis and the carbon cycle. It explains that:
1) Photosynthesis uses energy from sunlight to convert carbon dioxide and water into oxygen and carbohydrates like sugar, storing the sun's energy.
2) Carbon cycles between the atmosphere, living things, oceans, soil and fossil fuels as part of the global carbon cycle. Green plants and algae absorb carbon dioxide and release oxygen through photosynthesis.
3) Photosynthesis occurs in chloroplasts and has two stages - the light dependent reactions which require sunlight, and the light independent dark reactions which can occur with or without light but are more efficient in darkness.
OXYGEN CYCLE
Ali Hyder presented on the oxygen cycle to the Microbiology and Biotechnology department. The presentation covered definitions of key terms like biogeochemical cycles and oxygen. It explained that oxygen is produced primarily through photosynthesis by plants and some through interactions with sunlight and water vapor. Oxygen gets used up through respiration by animals and organisms, decomposition of dead matter, rusting of metals, and combustion. The oxygen cycle occurs as plants produce oxygen through photosynthesis during the day, which is then used by organisms for respiration and releases carbon dioxide, which plants then use again at night through photosynthesis, repeating the cycle.
Environmental engineering - oxygen cycle
The oxygen cycle describes the movement of oxygen between the atmosphere, biosphere, and lithosphere. Oxygen is involved in key processes like photosynthesis, respiration, combustion, and decomposition. Photosynthesis produces oxygen from carbon dioxide and water, while respiration, combustion, and decomposition consume oxygen to produce carbon dioxide. The document outlines the importance of oxygen for life on Earth and in the different spheres, as well as how oxygen levels have changed over time due to biological and geological processes.
4. the oxygen cycle
Oxygen is a colorless, odorless gas that is less dense than air and a poor conductor of heat and electricity. It cycles between the atmosphere, plants, animals, and oceans through photosynthesis and respiration. Photosynthesis produces oxygen as a byproduct in plants, which is then used by animals through respiration and releases carbon dioxide back into the atmosphere. Oxygen levels on Earth have increased over time as photosynthesis evolved and continues to be balanced between the atmosphere and bodies of water.
Carbon-Oxygen Cycle
The document discusses the carbon/oxygen cycle which involves four main processes:
1. Photosynthesis where plants take in carbon dioxide and water to release oxygen and sugar using energy from the sun.
2. Respiration where animals take in oxygen and sugars to release carbon dioxide, water, and energy.
3. Combustion which is the burning of fossil fuels like coal, gas, and oil, releasing carbon dioxide. This over-contribution of carbon dioxide is accelerating global warming.
4. Decomposition where dead plants and animals are broken down by insects, fungi and bacteria, returning carbon and other elements to the soil and air.
Organic compounds and plants
Plants are important because they produce oxygen and are producers that make their own food through organic compounds like carbohydrates. All organisms obtain energy from carbohydrates, which are organic compounds containing carbon, hydrogen, and oxygen. There are two main types of organic compounds - hydrocarbons which contain carbon and hydrogen, and come in saturated and unsaturated forms. Saturated hydrocarbons have all carbon atoms bonded to hydrogen atoms, while unsaturated hydrocarbons still have spaces to bond with more hydrogen.
Oxygen cycle
The oxygen cycle describes the movement of oxygen gas through the atmosphere, biosphere, hydrosphere, and lithosphere. Oxygen is produced through photosynthesis by plants and released into the atmosphere. Aerobic organisms like animals then use this oxygen for respiration, exhaling carbon dioxide back into the atmosphere. Oxygen dissolves in water and is used by aquatic life in the hydrosphere. The lithosphere contains oxygen in minerals like silica and oxides. This cycle is important for supporting aerobic respiration in humans, animals, and aquatic organisms as well as for decomposition.
Requirements for C, H & O
This document discusses three key elements - carbon, hydrogen, and oxygen - that are essential for life. It notes that carbon is required for important biomolecules like proteins, carbohydrates, lipids, and nucleic acids. Hydrogen is a major element in organic compounds and performs roles in pH maintenance, hydrogen bonding, and energy release. Oxygen makes up 20.8% of the atmosphere, is used in cellular respiration, and is found in organic molecules; it is continuously replenished through photosynthesis.
Carbon cycle
The carbon cycle describes the movement of carbon through Earth's atmosphere, oceans, soil, and living things. Carbon is absorbed by plants through photosynthesis and enters the biosphere, and is released back into the atmosphere through respiration and decomposition. Burning fossil fuels has increased the amount of carbon dioxide in the atmosphere, contributing to global climate change. The carbon cycle is essential for life and affects Earth's climate.
Carbon cycle
Carbon is the fourth most abundant element in the universe and is the building block of all living things. It cycles through ecosystems in various forms and pathways. Carbon exists in the lithosphere, atmosphere, biosphere, and hydrosphere. The carbon cycle involves the exchange of carbon between living things and the air, soil, oceans, and fossil fuels through processes like photosynthesis, respiration, and decomposition.

This document discusses carbon compounds and macromolecules that are essential for life. It explains that carbon can form strong bonds to other carbon atoms and a variety of elements, allowing it to make chains and complex molecules. The four main types of macromolecules are carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates include sugars and starches, lipids include fats and oils, nucleic acids are made of nucleotides, and proteins consist of amino acids. These macromolecules contain carbon along with other elements and are critical components of living things.
form-1-science-chapter-5-part2
The document discusses respiration and combustion, both of which require oxygen. It describes experiments that show organisms use oxygen and release carbon dioxide during respiration. Combustion is the rapid reaction of a fuel with oxygen that produces heat and light. Both processes are important for obtaining energy but can also pollute the air if not properly managed. The document emphasizes the importance of keeping the air clean for health and recommends various ways to reduce pollution such as planting trees and using alternative energy.
Biology Unit 3 Notes: Photosynthesis
Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce glucose and oxygen. It occurs in the chloroplasts of photosynthetic organisms, where chlorophyll absorbs sunlight that is used to convert carbon dioxide and water into oxygen and energy-storing glucose. Photosynthesis cycles matter and energy, converting sunlight into chemical energy stored in sugars and transforming carbon dioxide and water into oxygen and energy-rich organic compounds to fuel all other living things.
Respiration presentation
Respiration is the process by which cells convert biochemical energy from nutrients into ATP through a series of metabolic reactions involving the oxidation of molecules and reduction of others. Aerobic respiration uses oxygen as the final electron acceptor, while anaerobic respiration uses other molecules like sulfate, nitrate or sulfur. The energy from respiration is used to synthesize ATP, which cells use to power processes like biosynthesis, locomotion and transport.
Redox in everyday life
Everyday activities involve many redox reactions. Metals corrode through oxidation when exposed to oxygen and moisture. Bleach removes color through redox reactions that oxidize dyes. Breathalyzer tests use the oxidation of ethanol to change a solution from orange to green. Cut fruits brown through enzymatic oxidation reactions with oxygen in the air. Respiration, combustion, photosynthesis, and photography all involve important redox reactions as well.
LT2.1 Photosynthesis PowerPoint Notes
The document discusses photosynthesis and provides information about the process. It defines photosynthesis as the process by which sunlight energy is converted to glucose energy. It also notes that photosynthesis occurs in the chloroplasts of plants and involves the reactants of carbon dioxide, water, and sunlight being converted to the products of glucose and oxygen. Producers that undergo photosynthesis supply the entire food chain with energy.
The Carbon Cycle
1) The carbon cycle involves the exchange of carbon between living and non-living things through photosynthesis, respiration, and decomposition.
2) Plants take in carbon dioxide through photosynthesis and release oxygen, while animals release carbon dioxide through respiration and taking in oxygen.
3) When organisms die, decomposers break down their remains and release carbon back into the atmosphere as carbon dioxide, completing the carbon cycle.
Krypton
The document mentions Superman and jokingly refers to his home but provides no other context or information, followed by a list of noble gases including Krypton multiple times which is Superman's weakness.
Krypton science project
Krypton is a noble gas with an atomic number of 36 that was discovered in 1898 by Sir William Ramsay and Morris M. Travers while studying liquefied air. It makes up about 0.0001% of Earth's atmosphere and 0.0003% of Mars' atmosphere. Krypton is used in fluorescent light bulbs and photographic flash lamps.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
"Choosing proper type of scaling", Olena Syrota
Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Choosing The Best AWS Service For Your Website + API.pptx
