Lipids
Lipids are organic compounds made of carbon, hydrogen, and oxygen that are hydrophobic and insoluble in water. There are five main groups of lipids: fats and fatty acids, triglycerides, phospholipids, steroids, and wax. Fats contain fatty acids attached to glycerol. Fatty acids can be saturated or unsaturated. Triglycerides are esters formed from glycerol and three fatty acids. Phospholipids are similar to triglycerides but have a phosphate group replacing one fatty acid. Steroids have four interconnected carbon rings and side chains. Wax differs from fats in that it does not have a triglyceride structure. Lipids serve functions like energy storage

Lipids are organic compounds that are insoluble in water but soluble in organic solvents. They include fatty acids, triglycerides, phospholipids, and sterols. Lipids serve important structural and energy storage functions in living organisms. Fatty acids are the building blocks of lipids and contain long hydrocarbon chains with a carboxyl group. Saturated fatty acids are solid at room temperature while unsaturated fatty acids are liquid. Triglycerides are the main form of lipid storage and are composed of glycerol bonded to three fatty acid molecules. Phospholipids are important structural components of cell membranes. Classification of lipids includes simple, compound, and derived lipids based on their composition.

Lipids
Triglycerides are lipids composed of glycerol bonded to three fatty acid molecules. They are the main form of fat in the body and can be either solid or liquid at room temperature depending on whether the fatty acids contain saturated or unsaturated bonds. Triglycerides serve important functions as an energy store, building block of cell membranes, and as insulating and waterproofing layers. They are formed through a condensation reaction where fatty acids combine with glycerol, removing water molecules and forming ester bonds between the carboxyl end of the fatty acids and hydroxyl groups of glycerol.

3. Carbohydrates, lipids, proteins, and nucleic acids are organic compounds that contain carbon and provide structure and energy through molecules like glucose, fatty acids, amino acids, and nucleotides.
4. These organic molecules form complex macromolecules through condensation reactions, and carry out essential functions like energy storage, structure, catalysis, and heredity
Lipids - Edexcel A-Level Biology B Topic 1.2
Lipids are a group of organic molecules that play vital roles in organisms. They form integral parts of all cell membranes and are also used as an energy store. Fats and oils are important lipids that contain fatty acids and glycerol bonded together by ester bonds. Fats are solid at room temperature while oils are liquid. Phospholipids also contain fatty acids but have a phosphate group instead of a second fatty acid. Phospholipids form bilayer structures in cell membranes with their hydrophilic heads facing out and hydrophobic tails in the middle. This bilayer structure is the basis of all biological membranes.

Water makes up 50-90% of the human body and plays several important roles. It acts as a solvent, transports nutrients and wastes, regulates body temperature, and lubricates and cushions tissues. Water has unique properties like hydrogen bonding that allow it to exist in solid, liquid, and gas states and to dissolve many compounds. The major organic compounds in the body are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates include sugars and starches and serve as energy sources. Lipids include fats, phospholipids, and steroids and serve structural and insulating functions. Proteins are made of amino acids and serve many roles as enzymes, hormones, and structures. Nucleic acids like DNA
Cell Membranes and Lipids
The cell membrane is a selectively permeable biological membrane that separates the interior of cells from the outside environment and controls the movement of substances in and out of cells. It functions to protect the cell and is described as both hydrophilic and hydrophobic due to its structure and the polarity of molecules within it. The cell membrane also performs a key role in cell signaling. Chemically, the cell membrane is mainly composed of lipids, which are molecules consisting of carbon, hydrogen, and oxygen that do not dissolve in water but do dissolve in organic solvents. Phospholipids are a major component of cell membranes, consisting of glycerol, fatty acids, and phosphoric acid.

Lipids are a heterogeneous group of compounds that include fats, oils, steroids, waxes, and others. They are characterized by being relatively insoluble in water due to a lack of polarizing atoms, but soluble in nonpolar solvents. Lipids serve several important biological functions. They are a concentrated energy source, act as electrical insulators for nerves, are structural components of cell membranes, and are precursors for hormones and vitamins. Unsaturated fatty acids have lower melting points than saturated fatty acids of similar carbon chain lengths due to the kinks in their structure from double bonds, which prevent tight packing.

hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsPhenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

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.
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 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).

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
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.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
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.
