The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
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).
Phenomics assisted breeding in crop improvementIshaGoswami9
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.
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.
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.
ESPP presentation to EU Waste Water Network, 4th June 2024 “EU policies driving nutrient removal and recycling
and the revised UWWTD (Urban Waste Water Treatment Directive)”
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.
The binding of cosmological structures by massless topological defectsSérgio Sacani
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.
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.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
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.
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.

Here you see the BHL homepage, which you can access at biodiversitylibrary.org. Simply put, BHL is an open access digital library for biodiversity literature and archives.
We have a vision of “Inspiring discovery through free access to biodiversity knowledge.” We have been accomplishing this vision for 10 years now. BHL was born in 2006, and since then we have continuously provided free and open access to collections from the 15th-21st centuries. A majority of our collections are in the public domain, but we also work with rights holders to secure permission to digitize in copyright content and make it freely and openly available in BHL under Creative Commons licenses.
BHL operates as a consortium of natural history and botanical institutions and libraries around the world that work together to develop the library and digitize their own natural history collections and make them freely available in BHL. BHL participation is divided into Members, Affiliates, and Partners, each of which have varying degree of administrative and governance privileges. As of July 2016, we have 16 Members, 15 Affiliates, and a total of over 60 Partners across every continent (except Antarctica) contributing to BHL.
To date, BHL’s collections include over 50 million pages, which comprise over 110,000 titles and over 186,000 volumes. Another major service that BHL provides is taxonomic name recognition. Our primary audience is scientists and taxonomists, who are especially interested in locating material related to specific species or taxa. Using Global Names recognition and discovery tools and services powered by Global Names Architecture, BHL indexes the scientific names on the pages in the books in our collections and then allows users to search on those names to find content of interest. By searching on a taxonomic name in BHL, users can retrieve a bibliography listing all mentions of that name throughout BHL’s collections. To date, we’ve indexed over 169 million instances of taxonomic names throughout the collection. As previously mentioned, we also work with rights holders to secure permission to digitize in-copyright content in BHL. To date, we’ve received permission for over 490 in-copyright titles, amounting to agreements with over 215 licensors.
BHL also collaborates with and contributes content to a wide variety of partners. As mentioned, BHL is a long-time partner with EOL. In addition to contributing tagged images to EOL, BHL also contributes literature references to EOL species pages, and the taxonomic names in BHL are linked to the related EOL species pages. BHL is also an Associate Participant in the Global Biodiversity Information Facility (GBIF) and is a Member of TDWG (Taxonomic Database Working Group). Additionally, BHL contributes content to Europeana and is a digital content hub for the Digital Public Library of America (DPLA).
We believe that inspiring discovery isn’t just about providing access to literature and archives. It’s also about providing tools and services that make it easy for users to locate material of interest and keep that content in a format that meets their needs. Thus, BHL has a wide range of tools and services to support the needs of our users, such as the taxonomic name searching services previously mentioned. Additionally, our data can be freely accessed and downloaded through a variety of APIs (application programming interfaces) and data exports. We also support a variety of reference management tools, including an integration with Mendeley and bibliographic downloads in BibTeX and ENDNOTE formats. Users can also freely download our content, either by full PDF downloads or by selecting specific pages to create custom PDFs. We’ve generated over 486,000 custom PDFs to date. We are also working to index the articles in our collection to allow users to search by article, not just monograph or journal title. To date, we’ve indexed over 193,000 articles. We also work with CrossRef to assign DOIs to content in our collections, allowing users to easily cite our materials. To date, we’ve assigned over 103,000 DOIs to monographs and a few select articles.
Let’s explore some examples of tools and resources in BHL that can support research related to food security.
First, BHL’s taxonomic name finding tools, which are powered by Global Names Architecture and utilize the Global Names Recognition and Discovery and Global Names Index services, can help you locate literature on species of interest. All you have to do is search for a species…here i’m seaching on the Asian rice crop species...
And you can have returned to you a bibliography listing the books in BHL that mention that species. You can click on a page link in the page column to view any page in the bibliography.
This can help you uncover valuable information – and publications that you might not have been aware of – related to the species of interest. For example, you could use this service to help you find…
Information about wild crop relatives. In this example, you can see that this publication provides occurrence and habitat information for wild rice..
You can also find information on crop species, such as important information on their history. This shows an example from the potato, and this particular page, from 1597, represents the first printed picture of the potato. The publication provides insight into the early cultivation of the potato in England, within the same century as its introduction to Europe from the Americas. It also shows early misinformation about the crop, since the author, John Gerard, incorrectly asserts that the origin of the potato was Virginia.
You can also find information about livestock species and domestication history. For example, here’s a publication that provides information on the origins of various heritage chicken breeds.
BHL can also provide information on livestock and crop diseases and parasites, which can also provide an important historical perspective. For example, this publication details a variety of livestock tick species.
Finally, BHL also has a collection of over 25,000 seed and nursery catalogs. These catalogs help:
Document the introduction of new hybrids, varieties, and mutations
Document the introduction of chemical agents for insect and weed control
Detail early methods of cleaning, preserving, and shipping seeds
Document changes in garden plant popularity
Show changes in gardening and agricultural technology and tools over time
