NUTRITION IN LIFESPAN
This handout highlights the importance of nutrition across the entire lifespan. It talks about nutrition during pregnancy, lactation, childhood, adolescence and adults. Its very imperative to know what to eat and when to eat especially as we continue to age. Growth only proceeds up to a certain point when we have to be critical of the food we eat as any excess may results in chronic complications, especially becoming Obese and suffering from Diabetes Meliitus. This handout is going to help mostly the students of nutrition, midwifery and dietetics, and public health.
THE HUMAN DIGESTIVE SYSTEM
The human digestive system is approximately 9 meters long and runs from the mouth to the anus. It is made up of specialized regions where digestion takes place, including the mouth, esophagus, stomach, small intestine, and large intestine. Digestion is a two-phase process involving mechanical and chemical breakdown of food. Enzymes are secreted throughout the digestive tract to break down macromolecules into smaller molecules that can be absorbed and used by the body. Nutrients are then absorbed in the small intestine and remaining waste is eliminated through the large intestine and anus.

Digestive physiology of herbivorous fish
The knowledge of food and feeding habits and the physiology of digestion of any organism is most essential for development of artificial feed in culture practices. Fish and shellfish belong to the poikilothermous animal. The digestion process is somewhat different than the terrestrial animals. Similarly the mechanism of digestion and absorption process is quite different in fishes and shellfishes. The basic function of digestive system is to dissolve foods by rendering them soluble so that they can be absorbed and utilized in the metabolic process. The system may also function to remove dangerous toxic properties of certain food substances.
Fish generally change their feeding habits depending upon availability of food. So according to their feeding fishes are classified into different categories viz., predators, grazers, strainers, suckers and parasites.
THE HUMAN DIGESTIVE SYSTEM
The human digestive system is made up of a long digestive tract that stretches from the mouth to the anus. Food is broken down mechanically and chemically by different organs along the tract. Mechanical digestion begins in the mouth by teeth. Chemical digestion starts in the mouth by saliva and continues in the stomach by gastric juices and in the small intestine by enzymes from the pancreas, liver, and intestinal walls. Nutrients are absorbed in the small intestine and undigested waste is eliminated in the large intestine and anus. Proper digestion relies on balanced diet, chewing, drinking water, and exercise.

76 Chapter 3 | Digestion, Absorption, and Transport
The digestion of food begins even before you take that first bite. Just the sight and smell of homemade apple pie stimulates the release of saliva in
the mouth. The secretion of saliva and other digestive juices starts a cascade of
events that prepares the body for digestion, the chemical and mechanical
processes by which the body breaks food down into individual nutrient
molecules ready for absorption. Food components that aren’t absorbed are
excreted as waste (feces) by elimination. Although these are complex
processes, they go largely unnoticed. You consciously chew and swallow the
pie, but you don’t feel the release of chemicals or the muscular contractions
that cause it to be digested or the absorption of nutrient molecules through
the intestinal lining cells. In fact, you may be unaware of the entire process
until about 48 hours after eating, when the body is ready to eliminate waste.
In this chapter, we explore the processes of digestion, absorption, and
elimination, the organs involved, and the other biological mechanisms that
regulate our bodies’ processing of food and nutrients. We also discuss the causes
and treatments of some common gastrointestinal conditions and disorders.
What Are the Processes and Organs
Involved in Digestion?
LO 3.1 Describe the processes and organs involved in digestion.
Digestion, absorption, and elimination occur in the gastrointestinal (GI) tract, a mus-
cular tube approximately 20–24 feet long in an adult. Stretched vertically, the tube would
be about as high as a two-story building. It provides a barrier between the food within the

Digestion in Humans
The document summarizes digestion in human beings. It discusses the nutrients found in food and the three main types: carbohydrates, proteins, and fats. It explains that food must be digested into smaller molecules to pass through cell membranes and enter the bloodstream. Digestion is carried out by enzymes in the digestive system. The digestive system breaks down large food molecules through mechanical and chemical digestion. Mechanical digestion involves chewing and peristalsis, while chemical digestion uses enzymes to break nutrients into absorbable molecules.
2.19 Human Digestion Cambridge IGSSE Biology
Mechanical and chemical digestion break down food in the digestive system. Mechanical digestion involves physical breakdown of food using teeth and muscle movement. Chemical digestion uses enzymes to break down food into nutrients that can be absorbed. Most absorption occurs in the small intestine where enzymes from the pancreas and liver further break down nutrients into smaller molecules that pass into the bloodstream.
Digestive system
Digestion is process by which complex food get converted into simpler food so as to easily get absorbed into blood stream and act as a energy source.
The Digestive System.pptx
The digestive system consists of the digestive tract and accessory organs. The six main functions of the digestive system are ingestion, mechanical and chemical digestion, secretion, absorption, and excretion. The digestive tract includes the mouth, esophagus, stomach, small intestine, and large intestine. Accessory organs that aid in digestion include the teeth, tongue, salivary glands, liver, gallbladder and pancreas. In the small intestine, nutrients are absorbed into the bloodstream and lymphatic system.
Digestion absorptiondigestive secretions
Digestion and absorption, digestive secretions, their characteristic features: Digestion is the breakdown of food into particles small enough to cross the cellular barrier of the gastrointestinal (GI) system and be carried around the body in the circulation.
This occurs by both mechanical and chemical processes that begin in the mouth and generally end in the small intestine, where 90% of absorption takes place.
The other 10% takes place in the stomach and large intestine and often involves the help of the gut microbiota.
A small amount of absorption is also thought to take place in the mouth.
Mechanical digestion begins in the mouth with chewing and continues with segmental muscle contractions in the stomach and intestines.
Chemical digestion is primarily mediated by enzymes present in the secretions of the salivary glands, stomach and pancreas, and on the epithelial lining of the small intestine
Mechanical digestion is physical process in which food is broken into smaller pieces without chemically.
It begins with our first bite of food and continues as we chew food with our teeth into smaller pieces.
The process of mechanical digestion continues in the stomach. This muscular organ churns and mixes the food it contains, an action that breaks any solid food into still smaller pieces.
Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body.
Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
Carbohydrates must be broken down into simple sugars, proteins into amino acids, lipids into fatty acids and glycerol, and nucleic acids into nitrogen bases and sugars.
Some chemical digestion takes place in the mouth and stomach, but most of it occurs in the first part of the small intestine (duodenum).
Chemical digestion could not occur without the help of many different digestive enzymes. Enzymes are proteins that catalyze or speed up biochemical reactions.
Digestive enzymes are secreted by exocrine glands or by the mucosal layer of the epithelium lining the gastrointestinal tract.
In the mouth, digestive enzymes are secreted by salivary glands.
The lining of the stomach secretes enzymes, as does the lining of the small intestine.
Many more digestive enzymes are secreted by exocrine cells in the pancreas and carried by ducts to the small intestine
About 80 percent of digestible carbohydrates in a typical Western diet are in the form of the plant polysaccharide amylose, which consists mainly of long chains of glucose and is one of two major components of starch.
Additional dietary carbohydrates include the animal polysaccharide glycogen, along with some sugars, which are mainly disaccharides.
To chemically digest amylose and glycogen, the enzyme amylase is required. The chemical digestion of these polysaccharides begins in the mou

Nutrition in humans
A secretes bile which helps in emulsification of fats.
B is the hepatic portal vein.
C (i) Urea.
(ii) Urea is formed from the breakdown of excess amino acids in the liver. The amino acids are deaminated and the ammonia produced is converted to urea.
D The liver plays an important role in assimilation. It receives nutrients like glucose and amino acids from the hepatic portal vein after digestion and absorption in the small intestine. It converts excess glucose to glycogen for storage. It also converts excess amino acids into urea which is excreted in urine. This prevents toxic build up of ammonia in the body.

This document discusses ruminant digestion, including the anatomy and functions of ruminant digestive systems. Key points include:
- Ruminants have a four-chambered stomach (rumen, reticulum, omasum, abomasum) that allows them to digest cellulose with the help of microbes in the rumen.
- The rumen ferments ingested plant material and can regurgitate and rechew contents in a process called rumination.
- Each stomach compartment has a distinct capacity and function in digestion. The rumen makes up most of the stomach volume and serves as a storage area.
- Accessory organs like the liver and pancreas produce enzymes and

Key processes include chewing and saliva breakdown in the mouth, peristalsis through the esophagus, acid and enzyme breakdown in the stomach, further enzyme breakdown and absorption in the small intestine, water absorption and storage in the large intestine, and processing of nutrients by the liver.
FOOD SCIENCE & NUTRITION LECTURE 1.ppt
These notes are basics of human nutrition to learners at the diploma and undergraduate levels. They cover areas such as key terms in nutrition, importance of a balanced diet, uses of food in the diet among others.
Nutrition in humans
A secretes bile which helps in emulsification of fats.
B is the hepatic portal vein.
C (i) Urea.
(ii) Urea is formed from the breakdown of excess amino acids in the liver. The amino acids are deaminated and the ammonia produced is converted to urea.
D The liver plays an important role in assimilation. It receives nutrients like glucose and amino acids from the hepatic portal vein after digestion and absorption in the small intestine. It converts excess glucose to glycogen for storage. It also converts excess amino acids into urea which is excreted in urine. This prevents toxic build up of ammonia in the body.
LECTURE-1 Digestion.ppt
This document discusses ruminant digestion, including the anatomy and functions of ruminant digestive systems. Key points include:
- Ruminants have a four-chambered stomach (rumen, reticulum, omasum, abomasum) that allows them to digest cellulose with the help of microbes in the rumen.
- The rumen ferments ingested plant material and can regurgitate and rechew contents in a process called rumination.
- Each stomach compartment has a distinct capacity and function in digestion. The rumen makes up most of the stomach volume and serves as a storage area.
- Accessory organs like the liver and pancreas produce enzymes and

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

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.

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.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation
Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.
