This document provides information about beneficial insects. It begins by defining beneficial insects as those whose products have commercial value, those that act as pollinators, and those used for biological control, soil health, and more. It then lists and describes 10 categories of beneficial insects, including those producing commercially valuable goods like honey bees and silk worms, insect pollinators, natural predators, and those of educational/scientific value. For each category, various insect examples are given along with pictures to illustrate. The document provides a detailed overview of beneficial insects and their many important roles.
1. The abdomen of insects is segmented, with the basic number being 11 segments plus a telson bearing the anus. The 8th and 9th abdominal segments in females and the 9th in males contain external reproductive organs or genitalia.
2. Abdominal segments contain structures like spiracles, tympanums, and appendages that vary between insect groups. Appendages include styli, collophores, retinacula, furculae, gills, dolichasters, and prolegs.
3. Winged adults have appendages like cornicles, caudal breathing tubes, cerci, median caudal filaments, pygostyles, anal styli,
This document describes different types of insect eggs and pupae. It discusses eggs that are laid singly, such as sculpted, elongated, rounded, or floating eggs, as well as eggs laid in groups through pedicellate stalks, barrels, oothecae, pods, cases, or masses. The document also examines three main types of pupae: obtect pupae where appendages are glued down; exarate pupae where appendages are free; and coarctate pupae that form within the hardened last larval skin.
Entomology is the scientific study of insects. Insects constitute the largest class of living organisms, comprising about 72% of all known animal species. They originated 350-500 million years ago and have been able to dominate other animal groups due to several structural, developmental, behavioral and physiological adaptations. Their small size, hard exoskeleton, high fecundity, specialized food habits, parthenogenic reproduction, diverse habitats and protective strategies have allowed insect populations to thrive with minimal competition for resources.

The document summarizes the insect nervous system. It describes how the nervous system is responsible for coordinating the insect's behavior through axonic and synaptic conduction between neurons. The central nervous system contains a brain and ventral nerve cord with ganglia. Sensory neurons detect stimuli and motor neurons transmit signals to muscles. Neurotransmitters and insecticides can act on different targets in the synaptic cleft to disrupt signaling. In summary, the insect nervous system allows for coordinated behavior through transmission of electrical impulses between neurons in the central nervous system and to muscles.
This document summarizes the tanning process of cockroach ootheca (egg cases). It explains that the female cockroach carries the ootheca until the eggs hatch. The ootheca hardens through a natural tanning process where secretions from the left and right collateral glands of the female interact. The left gland secretes structural protein and an enzyme, while the right gland secretes an acid. When mixed, the acid is released and oxidized to form quinone, which cross-links the protein molecules, hardening the ootheca into a protective sclerotin casing. A schematic representation is provided to illustrate the interaction of secretions from the two glands during tanning.
Mr. Sabhavat Srinivasnaik presented on measurements of food utilization by phytophagous insects. There are two main methods for measuring food utilization - the gravimetric method and calorimetric method. The gravimetric method involves measuring food intake, weight gain of the insect, and fecal production to calculate various nutritional indices like consumption index, growth rate, efficiency of conversion of ingested food, and approximate digestibility. The calorimetric method uses indicators like chromium oxide that are added to the food and then measured in the feces and insect body to determine food absorption. A case study was presented and conclusions discussed the importance of understanding nutrient concentrations and plant resistance mechanisms for insect rearing and

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
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.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
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 ForwardLeonel Morgado
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.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
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.
