The digestive system breaks down food into smaller molecules that can be absorbed and used by the body. It converts foods into sugars, proteins, and fats that are absorbed into the bloodstream. The major stages of digestion are chewing, swallowing, stomach breakdown using acids and enzymes, further breakdown in the small intestine using juices and enzymes from the liver and pancreas, and absorption of nutrients in the small intestine. Undigested material then moves to the large intestine where water is absorbed before waste is excreted.

Digestive system
The digestive system breaks down food into nutrients that can be absorbed and used by the body. It begins with ingestion in the mouth, where teeth and saliva begin breaking down food. The food then moves through the esophagus and into the stomach where acids and enzymes further digest it. The partially digested food moves into the small intestine, where most digestion and absorption occurs with help from liver, pancreas and intestinal glands. Undigested waste then moves into the large intestine where water is absorbed before elimination of solid waste through the rectum and anus.

A balanced diet consists of carbohydrates, proteins, lipids, vitamins, minerals, dietary fiber, and water consumed in proper proportions. Scurvy results from a severe lack of vitamin C over 3 months and was common in sailors, causing bleeding gums and limb pain. Rickets, caused by vitamin D deficiency, leads to poor bone development and deformities in children. The digestive system breaks food down through mechanical and chemical digestion before nutrients are absorbed and waste is excreted. Mechanical digestion involves chewing and stomach churning, while chemical digestion uses enzymes to break molecules into absorbable components.
Digestion
The human digestive system breaks down food into smaller molecules that can be absorbed and used by the body. Digestion begins in the mouth where food is broken down by chewing and enzymes in saliva. It then travels to the stomach where it is further broken down by acids and enzymes. Nutrients are then absorbed in the small intestine with the help of enzymes from the pancreas and liver. Undigested waste moves to the large intestine where water is absorbed before elimination from the body as feces.
The Digestive System
The digestive system breaks down food into nutrients that the body can use for energy. It consists of the oral cavity, esophagus, stomach, small intestine, large intestine, rectum, and anus. The mucosa lining of the mouth, stomach, and small intestine produces juices to break down food into a usable form that is then absorbed and distributed throughout the body. Problems with the digestive system can arise from improper diet, injuries, or diseases like Crohn's disease or irritable bowel syndrome.

C26 Digestion In Human
Digestion is the process by which food is broken down into smaller molecules that can be absorbed and used by the body. The human digestive system consists of the digestive tract and several organs that help break down food. As food moves through the mouth, stomach, and small and large intestines, it is broken into smaller pieces and has nutrients extracted. Enzymes produced by glands like the salivary glands, liver, and pancreas help break down proteins, carbohydrates and fats into molecules small enough to be absorbed and used by cells throughout the body.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

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.

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.

Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

Digestive system.pptx
- 2. Introduction Why we need food? We need food to fuel our bodies for energy, growth and repair.
- 3. What is digestive system? Digestion is a simple process where large insoluble food particles are broken down into smaller water soluble molecules. So they can be absorbed by blood and give energy to our body.
- 4. Definition The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
- 5. Stages of Digestive System • Chewing When you chew your food, the food particles breakdown into little pieces that are easier to swallow
- 6. Continue… What helps our food to break even more? Saliva Enzymes Food particles
- 7. • Swallowing Tongue helps to push the food particles down your throat The food travel through a long pipe called ESOPHAGUS/Food pipe
- 8. • Stomach Food particles hang out here for about four hours. During these hour stomach releases lots of acid and enzymes.
- 9. Enzymes Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies
- 10. • Small Intestine Juices from liver and pancreas help food particles to break down further Liver secrete bile that helps break down fats Pancreas releases enzymes that helps to digest all food particles
- 11. What happened to the food particles that are not absorbed?
- 12. • Large Intestine The food particles that are not absorbed reach the large intestine The large intestine absorbs water and other particles and sends the waste material out of your body.
