OSMOSIS
Osmosis is the spontaneous movement of water molecules through a semi-permeable membrane from a region of lower solute concentration to higher solute concentration in order to equalize the concentrations. It provides the means for water transport into and out of cells. The direction of osmosis depends on the solute concentrations on both sides of the membrane - if one side has a higher concentration than the other, water will diffuse into the lower concentration side. This movement of water allows cells to remain turgid and control their volume under different osmotic conditions by taking in or releasing water through osmosis.

Osmosis
Osmosis is the passive movement of solvent molecules through a semi-permeable membrane from a region of lower solute concentration to higher solute concentration. It does not require energy. Diffusion is the passive movement of particles from an area of higher concentration to lower concentration until equilibrium is reached. It can occur in solids, liquids and gases and does not require a membrane. Solutions can be isotonic, hypertonic or hypotonic depending on solute concentrations inside and outside the cell. Osmosis influences plant and animal cell structure and functions like nutrient transport and waste removal.
Osmosis
Osmosis is the movement of water molecules across a semi-permeable membrane from an area of higher water concentration to lower concentration until equilibrium is reached. Water molecules move randomly based on their kinetic energy. For osmosis, the potential of water to move is measured by osmotic potential, which is negative when other substances are dissolved in water. Water always moves from areas of lower to higher water potential. Osmosis plays a key role in transporting water and nutrients in the body and growth in plants. It can also be used to purify water in reverse osmosis desalination processes.
Passive Transport Notes
Passive transport involves the movement of substances down their concentration gradient without requiring energy. There are four main types of passive transport: diffusion, osmosis, facilitated diffusion, and diffusion through ion channels. Osmosis is the diffusion of water across a semipermeable membrane from an area of high water concentration to low concentration and does not require energy. When a cell is placed in solutions of different concentrations, water will move in or out of the cell by osmosis to reach equilibrium. [/SUMMARY]
Diffusion
This document discusses diffusion, including its definition, types, factors that affect it, and functions. Diffusion is the movement of molecules from an area of high concentration to low concentration through random motion. It occurs passively in liquids and gases. There are two main types: passive diffusion, which involves molecules moving directly through a medium or membrane, and facilitated diffusion, which requires transport proteins. Factors like temperature, concentration gradient, surface area, and particle size influence the diffusion rate. Diffusion plays a key role in important biological processes like gas exchange, nutrient absorption, and signal transmission in the body.
Active and passive transport
The document discusses two types of transport across the plasma membrane: passive transport, which moves particles down a concentration gradient without requiring energy, and active transport, which moves particles against a concentration gradient and requires energy. Passive transport occurs through diffusion or facilitated diffusion, while active transport uses carrier proteins or endocytosis.
Osmosis and Osmotic Pressure
Osmosis is the net diffusion of water molecules from a dilute solution into a more concentrated solution through a semi-permeable membrane due to a concentration gradient. Osmotic pressure is the excess pressure that must be applied to a solution to prevent the passage of solvent into the solution, and it is measured in units called osmoles. Osmotic pressure follows two laws: πV = nRT and π = cRT, where π is osmotic pressure, V is volume, n is moles of solute, R is the gas constant, T is temperature, and c is molarity. Applications of osmosis include water desalination through reverse osmosis, measuring

Osmosis
Definition- Process - Egg experiment
The flow of the solvent through a semipermeable membrane from pure solvent
to solution, or from a dilute solution to concentrated solution, is termed Osmosis
(Greek Osmos = to push).
The phenomenon of osmosis is the spontaneous passage of a pure solvent into a
solution separated from it by a semipermeable membrane, a membrane permeable
to the solvent but not to the solute.
• As time passes, the volume of the solution increases and that of the solvent
decreases. Eventually the liquid levels stop changing, indicating that the system has
reached equilibrium.

STAINING TECHNIQUES AND TYPES PROCEDURE.
This document discusses various staining techniques used in microscopy to visualize bacteria and other microscopic organisms. It describes different types of stains including simple stains that color all structures the same and differential stains that color different structures differently. Specific staining techniques are explained, including Gram staining to distinguish between Gram-positive and Gram-negative bacteria, acid-fast staining for mycobacteria, and endospore staining. The document provides details on procedures, requirements, and results for common staining methods.
Passive transport
Passive transport allows substances to cross the cell membrane without expending energy. There are three main types of passive transport: diffusion, osmosis, and facilitated diffusion. Diffusion is the movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water across the cell membrane and is dependent on solute concentrations inside and outside the cell. Facilitated diffusion uses carrier and channel proteins to transport molecules that cannot diffuse directly through the membrane down their concentration gradient.
Diffusion osmosis
Diffusion and osmosis are important transport processes in living cells. Diffusion is the movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water across a selectively permeable membrane from an area of higher water concentration to lower. When a red blood cell is placed in distilled water, osmosis causes water to enter the cell, making it swell and burst due to the higher water concentration outside. These processes allow cells to exchange gases, take in nutrients and water, and eliminate waste, which is essential for maintaining homeostasis.
Classification of enzymes
This document categorizes enzymes into six main classes based on their catalytic activity: 1) Oxidoreductases catalyze redox reactions such as dehydrogenation and oxidation. 2) Transferases transfer atomic groups between molecules, like transaminases transferring amino groups. 3) Hydrolases catalyze hydrolysis reactions by adding water, as seen in maltase breaking maltose into glucose. 4) Lyases break chemical bonds without water, such as decarboxylases removing carboxyl groups. 5) Isomerases catalyze conversion between isomers by moving atomic groups. 6) Ligases catalyze bond formation using ATP, for example DNA ligase in DNA synthesis.
Types of culture media
Culture media are used to grow microorganisms outside the body for research and diagnostic purposes. There are different types of culture media classified based on physical state (solid, semi-solid, liquid) or ingredients (simple, complex, synthetic). Solid media like agar are used to isolate colonies, while liquid broths allow uniform growth. Special media can be enriched, selective, differential, or designed for transport or anaerobes. Proper preparation and sterilization of media is required to avoid contamination.
Enzymes
Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in cells without being consumed. They are highly specific and can catalyze reactions like metabolism. Enzymes are composed of amino acid chains and sometimes require cofactors to function. They act by binding to substrates at active sites in a lock-and-key or induced fit mechanism. Factors like temperature, pH, concentration of enzymes and substrates affect reaction rates. Enzymes play important roles in the body like digestion, synthesis, degradation of molecules, and protection against pathogens.
Osmotic pressure & Colloids
Osmosis is the movement of molecules from higher concentration to lower concentration via a semipermeable membrane. Osmotic pressure is the pressure required to stop osmosis.
Osmosis, diffusion presentation

Osmosis is defined as the diffusion of water through a semi-permeable membrane. The document explains that osmosis will stop when turgor pressure builds in plant cells due to their rigid cell walls. It also notes several significances of diffusion and osmosis, including their roles in gas exchange, mineral uptake, and transpiration.

TRANSPORT ACROSS CELL MEMBRANE
This document discusses cell membrane transport mechanisms. It begins by outlining the key topics to be covered, including the importance of cell membranes, types of transport mechanisms, and details on active and primary/secondary active transport. It then provides information on the structure of the cell membrane, including the lipid bilayer and membrane proteins. Various types of membrane transport mechanisms are defined, such as simple diffusion, facilitated diffusion, osmosis, and vesicular transport processes like endocytosis and exocytosis. Factors influencing diffusion rates and osmotic concepts like tonicity are also examined.
Facilitated diffusion
Facilitated diffusion is the movement of substances across a membrane along a concentration gradient, aided by transport proteins like channel and carrier proteins. Channel proteins form hydrophilic pores through the membrane that allow rapid diffusion of small molecules and ions. Carrier proteins bind molecules and change shape to transport them, moving more slowly than channels. Gated channel proteins selectively open and close pores in response to stimuli like voltage changes, regulating substance flow across the membrane. Factors like temperature, concentration gradient, distance, and molecule size affect the rate of facilitated diffusion.

Culture media
Culture medium or growth medium is a liquid or gel designed to support the growth of microorganisms. There are different types of media suitable for growing different types of cells. Here, we will discuss microbiological cultures used for growing microbes, such as bacteria ,fungi, yeast & algae.
Centrifugation
Centrifugation is a process that uses centrifugal force to separate mixtures of substances based on density differences. It involves spinning a sample in a centrifuge which causes denser components to migrate outward while less dense components migrate inward. There are various types of centrifugation techniques used for separation in industrial and laboratory settings, including differential centrifugation, density gradient centrifugation, and ultracentrifugation. Centrifugation has many applications such as separating solids from liquids in water treatment, separating blood components, and separating particles in industrial processes.
Osmotic pressure
This presentation discusses osmotic pressure and its related concepts. Osmosis is the passage of solvent through a semipermeable membrane from a less concentrated to a more concentrated solution. Osmotic pressure is the minimum pressure required to prevent osmosis, or the flow of water across the membrane. It further defines isotonic, hypertonic, and hypotonic solutions and outlines methods to determine osmotic pressure. Van't Hoff's law relates osmotic pressure to concentration and temperature. Osmotic pressure has important applications including desalination and maintaining fluid balance in the body.
Microscopy
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy.
Respiration
The document discusses respiration in three sentences:
Respiration involves the breakdown of glucose and other organic molecules to release energy through aerobic and anaerobic pathways. Aerobic respiration uses oxygen and occurs in mitochondria, producing much more ATP than anaerobic respiration. The energy from respiration is used to synthesize ATP, which acts as the "energy currency" of cells and is used to power metabolic reactions.
Enzymes
This document provides an overview of enzymes, including their chemistry, classification, mechanisms of action, kinetics, inhibition, and activation. It begins with the basic introduction that enzymes are protein catalysts that speed up biochemical reactions. It then covers enzyme structure and components like cofactors. The major sections explain classification of enzymes based on reaction type, mechanisms like induced fit and catalytic types, kinetics concepts like Michaelis-Menten modeling and factors affecting reaction rates, and types of inhibition like competitive and noncompetitive. The document aims to comprehensively summarize the key topics relating to enzymes.

Osmotic Power
This document outlines osmotic power, which generates energy from the difference in salt concentration between seawater and freshwater. It works via pressure retarded osmosis (PRO) where freshwater naturally moves through a semi-permeable membrane into higher salinity seawater, increasing pressure. This pressure powers a turbine to generate electricity. Key components include membrane modules to separate the waters, filters to optimize membrane performance, and a turbine/generator. Experimental results showed a prototype achieving over 90% efficiency and the potential to scale installations by adding more membrane modules.
Osmotic power plant
Power consumption is increasing globally, requiring more power generation which sometimes causes environmental pollution. Non-conventional renewable power plants like hydro, solar, geothermal, and wind are encouraged but affected by climate and cannot operate continuously. Osmotic power plants, a promising new technology, use semipermeable membranes and osmosis to generate pollution-free power from the difference in salt concentration between fresh and salt water, and can operate 24/7. The first prototype was built in Norway in 2009. While expensive now, osmotic power has potential to provide up to 50% of the EU's current power from its global annual potential of 1600-1700 terawatt hours.

Statkraft is developing osmotic power as a new renewable energy technology. Osmotic power uses osmosis, the natural process by which water moves from a low salt concentration to a high one, to generate electricity. Statkraft has built a prototype osmotic power plant in Norway to test membrane and system components at a small scale. The technology has potential for cost reductions through larger membrane elements, higher system efficiencies, and economies of scale in larger plants. Statkraft is working with partners on membrane and system development to advance osmotic power toward commercialization.
OSMOSIS -BIPIN S
Osmosis is the spontaneous movement of water molecules through a semi-permeable membrane from an area of higher water concentration to lower water concentration in order to equalize the concentration of water molecules on both sides of the membrane. The movement occurs due to differences in solute concentration between solutions separated by the semi-permeable membrane. Osmosis plays a key role in transporting water into and out of cells and the response of cells to their external environment depends on whether the outside solution is hypo-tonic, iso-tonic, or hyper-tonic compared to the cell cytoplasm.
Omotic
Osmotic power is generated by exploiting the pressure difference created across a semi-permeable membrane that separates fresh water and salt water reservoirs. Fresh water flows through the membrane into the higher salinity salt water reservoir, creating pressure that can be used to drive turbines and generate electricity. Osmotic power plants have the advantages of being renewable, producing electricity reliably without carbon emissions. However, they also have high upfront costs and require access to a steady source of fresh and salt water with a sufficient salinity gradient.
Osmotic energy
The document discusses osmotic power, a sustainable energy source that uses differences in salt concentrations between freshwater and saltwater to generate electricity. It notes that Norway built the first osmotic power plant, which is 13 times more efficient than current sustainable options and produces energy through an osmotic process that involves freshwater and saltwater at different salt concentrations and pressures, generating 1.62 megawatts of power emission-free. However, the technology also has high costs and requires frequent filter changes and emptying/refilling of containers.
Osmosis
Osmosis is the movement of water molecules from an area of high water potential to low water potential through a semi-permeable membrane. Solutions can be isotonic with equal solute concentration, hypertonic with higher solute concentration, or hypotonic with lower solute concentration. Osmotic pressure reduces water potential and is important for animal and plant cells to regulate water content and prevent changes in cell volume that could disrupt cellular functions. Cells will gain water if the surrounding medium is hypotonic, lose water if it is hypertonic, and not change if the medium is isotonic.
Osmosis
La ósmosis es el flujo de agua a través de una membrana semipermeable hacia la solución con mayor concentración de solutos. La presión osmótica es la fuerza que impide la ósmosis y depende directamente de la concentración de solutos. La tonicidad se refiere a si una solución es hipertónica, hipotónica o isotónica en relación a otra. Existen diferentes mecanismos de transporte a través de membranas como la difusión facilitada, el transporte activo primario y secundario.
Hydraulic Hybrid vehicles
This document discusses hydraulic hybrid vehicles (HHVs), which use pressurized fluid as a secondary power source alongside an engine to drive wheels. HHVs can recover up to 75% of braking energy using accumulators, far more than conventional hybrids, leading to 30-50% lower emissions and 50-100% greater fuel efficiency. However, HHVs also have higher costs due to expensive accumulators and risks of explosions from high pressures.

Diffusion Osmosis
The document discusses diffusion and osmosis, which are important processes that allow cells to maintain homeostasis. Diffusion is the movement of molecules from an area of high concentration to low concentration.

Content based lcd backlight power reduction
The document proposes two new algorithms - the New Backlight Dimming Algorithm (NBDA) and the New Image Enhancement Algorithm (NIEA) - to simultaneously reduce LCD backlight power consumption and enhance image contrast using content-based histogram analysis.
The NBDA analyzes image histograms to select the appropriate LCD backlight current level to reduce power. The NIEA then enhances image contrast to compensate for brightness changes from dimming the backlight, maintaining image quality.
Experimental results on an FPGA platform show the algorithms can on average reduce power consumption by 47% while improving image enhancement ratio by 6.8%, assessed using PSNR and SSIM metrics, allowing viewers to perceive little change in image quality despite
Collaboration BOF presentation - IDCC 2015
Chris Awre discusses collaboration as key to addressing challenges with digital archives. Born-digital archives require working beyond any single institution. Collaboration allows archives to deliver services by sharing skills and resources. Successful collaborations include specific subject or use case groups. Barriers include inertia, limited capacity, and lack of follow through. Case studies on the AIMS project and Hydra initiative show benefits of practical collaboration and developing common infrastructure. Network-level activities can better support local services through resource sharing. The presentation calls for discussion on enabling collaboration while addressing concerns.
About Osmosis
The document discusses the process of osmosis and related concepts. It defines osmosis as the spontaneous movement of water across a semi-permeable membrane from a less concentrated solution to a more concentrated one. It distinguishes osmosis from diffusion and defines terms like hypertonic, hypotonic, and isotonic solutions. Examples of osmosis applications include how it assists plants and is used in food preservation and kidney dialysis. It also discusses osmotic pressure and provides examples of calculating osmotic pressure and solute concentration.
Trans effect
1. The trans effect refers to the observation that certain ligands increase the rate of ligand substitution when positioned trans to the departing ligand.
2. This effect was first discovered in 1926 when studying platinum complexes, where it was found that ammonia preferentially substituted the chloride ligand cis rather than trans to the nitrite ligand in Pt(NO2)Cl3 complexes.
3. Two main theories have been proposed to explain the trans effect - the polarization theory involving electrostatic weakening of the trans metal-ligand bond, and the pi-bonding theory involving back-donation of electron density from the metal into the pi* orbitals of ligands like NO2 weakening the trans bond.

Chemistry
Osmosis is the movement of solvent molecules through a semi-permeable membrane from an area of higher solvent concentration to lower solvent concentration. The document defines hypertonic, isotonic, and hypotonic solutions and explains how osmosis causes cell shrinkage or swelling depending on the solution. It also provides examples of how osmosis is used in desalination, food concentration, and dairy concentration processes.
Osmosis Definition.docx
Osmosis and reverse osmosis are processes involving the movement of solvent molecules across a semi-permeable membrane. Osmosis occurs naturally from an area of lower solute concentration to higher concentration. Reverse osmosis applies pressure to overcome this, forcing solvent from the higher concentration side to the lower side. It is used in water purification to remove salts and other contaminants, making the water potable. The document provides detailed explanations, examples, and diagrams of both processes.
Planf physilogy
Osmosis: is the movement of water from a high concentration to a low concentration through a partially permeable membrane. It is a special type of diffusion
Osmosis: is a process in which a fluid passes through a semipermeable membrane, moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute is present in high concentrations.
Osmosis n diffusion
The physical processes of diffusion and osmosis involve the movement of materials across cell membranes along concentration gradients without expending energy. Diffusion is the movement of substances from an area of higher concentration to lower concentration and can occur through gas, liquid, or semipermeable membranes. Osmosis specifically refers to the diffusion of water molecules through a semipermeable membrane from an area of higher water concentration to lower concentration. Experiments can demonstrate osmosis using a potato or thistle funnel surrounded by solutions of different concentrations.
easylearningwithned.blogspot.com-Difference between Osmosis and Diffusion.pdf
The document compares and contrasts osmosis and diffusion. Osmosis is the movement of a solvent like water across a semi-permeable membrane from an area of higher solvent concentration to lower concentration. Only the solvent molecules move. Diffusion is the movement of solute molecules from an area of higher concentration to lower concentration without a membrane. Both solute and solvent molecules can move, and the process equalizes concentrations and cannot be reversed.
Reverse osmosis ppt
Reverse osmosis is a water purification process that uses a semi-permeable membrane under pressure to separate dissolved impurities from water molecules. It can remove over 99% of ions, particles, bacteria and other contaminants by allowing water to pass through the membrane while blocking dissolved salts and unwanted molecules. Some key benefits of reverse osmosis include effectively removing many types of chemical and biological impurities from water, enabling water desalination and purification for medical and other uses.
Osmosis project of chemistry
Osmosis is the diffusion of water through a semipermeable membrane from an area of lower solute concentration to higher solute concentration. Cell membranes allow water to pass through but not larger molecules like sugars. This process is important for plants to absorb water and minerals. In this experiment, carrot tissue will be placed in solutions of varying strengths and weighed to measure how much water enters through osmosis.
Osmosis and Transport across the membrane.pptx
This document discusses osmosis and transport across membranes. It defines osmosis as the process by which water molecules pass through a semi-permeable membrane from an area of higher water concentration to lower concentration. There are different types of osmosis including endosmosis, exosmosis, and reverse osmosis. Transport across membranes can occur through passive transport mechanisms like diffusion and facilitated diffusion, or active transport which requires energy. Osmosis and transport are important biological processes that allow for nutrient intake, waste removal, and homeostasis in living cells and organisms.

The document provides equations to describe drug release from these systems driven by osmotic pressure.
Transfer of matter Diffusion - Osmosis -Dissolution rate
1. Mass transfer is the movement of mass from one location to another driven by concentration gradients and involves processes like diffusion, osmosis, and dissolution.
2. Diffusion is the spontaneous movement of molecules from an area of high concentration to low concentration while osmosis is the diffusion of a solvent through a semipermeable membrane.
3. Dissolution is the process where a solute enters solution when added to a solvent and involves wetting, immersion, and diffusion of molecules into the bulk solution. The dissolution rate is described by the Noyes-Whitney equation.
Membrane separation (osmotic)
Membrane separation techniques such as reverse osmosis, dialysis, and electrodialysis were presented. Reverse osmosis uses pressure to force water through a semi-permeable membrane to separate pure water from solutions like seawater. Dialysis relies on diffusion to separate low molecular weight solutes through a porous membrane. Electrodialysis uses ion exchange membranes and an electric current to transport ions between solutions. These membrane processes separate particles and molecules through mechanisms of sieving and diffusion.

MEMBRANE SEPARATION
This document discusses different membrane separation techniques including reverse osmosis, dialysis, and electrodialysis. Reverse osmosis uses pressure to force purified water through a semi-permeable membrane, leaving dissolved ions behind. Dialysis relies on diffusion across a semi-permeable membrane to remove low molecular weight solutes from fluids. Electrodialysis transports ions through ion exchange membranes under an applied electric potential to purify solutions.
osmotic pump
Osmotic drug delivery systems use osmotic pressure to provide controlled release of drugs over extended periods of time. They consist of a drug core surrounded by a semipermeable membrane with a delivery orifice. When exposed to fluids, osmotic pressure causes water to enter the system, dissolving the drug and pushing it out through the orifice at a controlled rate. The three main types are Rose-Nelson pumps, elementary osmotic pumps, and controlled porosity osmotic pumps. These systems offer advantages over traditional methods for conditions requiring prolonged, consistent drug levels.
AS Biology - Osmosis
Osmosis is defined as the net movement of free water molecules through a partially permeable membrane down a water potential gradient. It occurs when a cell is placed in a solution with a different osmotic concentration - the concentration of solutes that affect water movement. If the solution has a lower osmotic concentration than the cell (hypotonic), water will move into the cell. If it has a higher concentration (hypertonic), water will move out. Net water movement is always from the hypotonic to the hypertonic solution.
lecture 2.pptx
This document provides an overview of plasmolysis and osmosis in plant cells. It defines plasmolysis as when plant cells lose water and shrink away from their cell walls after being placed in a hypertonic solution. Osmosis, which is responsible for plasmolysis, is the movement of water across membranes from areas of higher water concentration to lower concentration. The document describes different types of plasmolysis (concave, convex) and explains how solutions can be hypotonic, isotonic, or hypertonic relative to plant cells. It also distinguishes osmosis, the movement of water, from diffusion, the movement of molecules.
Osmosis 2
Osmosis is the diffusion of water through a partially permeable membrane from an area of higher water concentration to lower concentration. It is important in plants and animals for maintaining homeostasis, or constant internal conditions. In animal cells, too little water causes cells to shrivel and too much causes them to burst. In plant cells, osmosis allows water movement into cells to swell the cytoplasm and press against cell walls, making the cells rigid and supporting stems and leaves. The fluid outside plant cells must have a higher water concentration to keep osmosis moving water into the cells.

The ozone layer
The ozone layer is a gas layer located in the stratosphere that protects life on Earth from UV radiation. CFCs released into the atmosphere were depleting the ozone layer by destroying ozone molecules. This was causing the ozone hole over Antarctica to grow and allowing more UV radiation to reach the Earth's surface, threatening life. In response, the international community adopted the Montreal Protocol to phase out CFC production, which has successfully led to the recovery of the ozone layer by 2050-2075 while also helping reduce greenhouse gases.

Mechanism of plant nutrient absorption by plant root and plant tissue
The document summarizes the mechanisms by which plants absorb nutrients through their roots and tissues. It discusses how nutrients reach the root via mass flow, diffusion, and root interception. It then explains the two main types of absorption - passive and active uptake - and how roots maintain electrical balance during absorption. It also briefly mentions stomatal and foliar absorption. In under 3 sentences, the key points are: Nutrients reach roots through mass flow, diffusion, and interception and are absorbed through either passive uptake along with water or active uptake requiring carrier proteins; roots export hydrogen ions to maintain electrical balance during cation absorption and bicarbonate during anion absorption; absorption also occurs through leaves via stomata or directly from nutrient-
Soil fractionation study
Physical fractionation techniques have often relied on the breakdown of soil structure into its textural classes or density fractions in order to study SOM dynamics. This appears to be inappropriate for investigating how soil structure is maintained. The bonding agents responsible for structure have been well defined, although the effects of farming systems on them are not fully understood. Techniques which can rapidly assess the impacts of management on bonding agents and structure are required in order to develop sustainable farming systems.

Distributing products efficiently and competitively
Marketing intermediaries such as agents, wholesalers, distributors, and retailers are an important part of the distribution channel. They perform marketing tasks faster and more cheaply than manufacturers and make markets more efficient by reducing transactions. The six types of utility they provide are form, time, place, possession, information, and service.
Wholesale intermediaries include merchant wholesalers, which take title to the goods they handle. Retail intermediaries sell directly to consumers using various strategies like intensive distribution, selective distribution, and exclusive distribution. Non-store retailing includes selling over the internet, through telemarketing, vending machines, and direct selling. Cooperation between channel members can occur through contractual agreements in a franchise
Economics the foundation of business
Economics is the study of how societies use scarce resources to produce and distribute goods and services. A nation's resources consist of natural resources like oil and timber, capital resources like manufactured goods, and labor resources like human skills and talent. Resources are allocated through a society's economic system to produce goods that meet people's needs for survival like food and clothing, as well as wants for non-essential items like entertainment goods. The economic system determines how resources, production, and distribution occur, and can be either a planned or free market economy. Understanding economics provides the foundation for comprehending business.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Targeting Hsp90 and its pathogen Orthologs with Tethered Inhibitors as a Diagnostic and Therapeutic Strategy for cancer and infectious diseases with Dr. Timothy Haystead.ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

- 3. Objectives: 1.) toexplainand understandtheprocess ofOsmosis; 2.) to differentiate hypertonic, hypotonic and isotonic solutions; 3.) enumerate some importantapplicationsofOsmosis;
- 4. MENU (Topicsto be discussed) • What is Osmosis? • Osmosis vs. Diffusion • Terms used inOsmosis • Applicationsof Osmosis • Osmotic Pressure
- 5. What is Osmosis? It is the spontaneous net movement of a solvent like water, across a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of themembrane.
- 6. Both are processes that equalize the concentration of two solutions but both differ in their nature and process. Diffusion involves solvent and solute particles to move to equalize concentrations from lower to higher concentrations. But no semi-permeable membrane is involved. It mainly occurs in gaseous state or within gas molecules and liquid molecules and usually does not need water for movement. How does osmosis differ from diffusion?
- 7. Example of diffusion may involve the following: (a) Perfume or Air Freshener where the gas molecules diffuse into the air spreading the aroma, and (b) diffusion of dye in water
- 8. On the other hand, in osmosis, only solvent particles move. Solute particles tend not to move and the movement is through the semi-permeable membrane. It may require liquids for movement and a semi-permeable membrane.
- 10. Terms usedin Osmosis 1.) Hypertonic used to refer to the solution with higher concentration or more solute. 2.) Hypotonic used to refer to the solution with lower concentration or less solute. 3.) Isotonic If both solutions have equal concentrations, they are said to be isotonic.
- 11. Applicationsof Osmosis So where can we usually use osmosis?How can human andother living organisms benefit from the concept of osmosis? 1. It assistsplants in receiving water. 2. It helps in the preservation of fruit andmeat. 3. It is used inkidney dialysis. 4. It can be reversed to remove saltandother impurities from water. 5. Osmotic generation of power.
- 12. Factors 1. Osmotic Pressure It is basically the pressure that would have to be applied to a pure solvent to prevent it from passing into a given solution by osmosis, oftenusedtoexpresstheconcentrationofthesolution.
- 13. Factors 2. Osmotic gradient The osmotic gradient is the difference in concentration between concentration between two solutions on either side of a
- 14. Variation 1. Reverse osmosis Reverse osmosis is a separation process that uses pressure to force a solvent through a semi-permeable membrane that retains the solute on one side and allows the pure solvent to pass to the other side, forcing it from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.
- 15. 2. Forward osmosis Osmosis may be used directly to achieve separation of water from a solution containing unwanted solutes. Forward osmosis is an area of ongoing research, focusing on applications in desalination, water purification, water treatment, food processing, etc. Variation
- 16. Conclusion Osmosis is the diffusion of water molecules through a selectively permeable membrane. The molecules move from an area of high concentration to an area of low concentration and vice-veca. Osmosis is important to plants because it is the way the plant gets water through its leaves and root hair cells Process of osmosis net movement of water into a cell percentage, Water was 90% inside the cell and 95% outside the cell
