Lake water chemistry
Temperature affects the life stages and survival of aquatic organisms, with different species having different temperature requirements. Turbidity is caused by suspended materials that scatter light in water and can come from sediments, plankton, or algae. It blocks light needed by plants and buries bottom dwellers. Dissolved oxygen is essential for aquatic animals to respire; levels below 3 ppm are stressful and below 2 ppm cannot support fish. Biological oxygen demand measures how much oxygen is needed to decompose organic material and wastes, with unpolluted waters having less than 5 mg/L. Nitrate and phosphates can accelerate algae growth when in excessive amounts and affect water quality. pH between 6.5-8.2

The Mycological flora of Clarias gariepinus exposed to sub-lethal concentrations of an oilfield wastewater were investigated. The concentrations included 0% (control), 10, 20, 30, 40, 50 and 60% respectively. Physico-chemistry and mycoflora of wastewater and tissues of Clarias gariepinus were
determined using standard methods. Mean values obtained were; temperature 25.93±6.7oC, pH 7.73±0.31, turbidity 40.33±1.53 NTU, salinity 6584±137mg/l, conductivity 15200±1058.68μs/cm, total dissolved solids 8436.33±501.68 mg/l, total suspended solids 4.67±0.58mg/l, alkalinity
1296.33±2168mg/l, dissolved oxygen 1.83±0.38mg/l, biochemical oxygen demand 1.3±0.7mg/l and Total hydrocarbon 40.54±50mg/l. Temperature, DO, BOD and THC were below allowable FEPA limits while all other components were higher. Mean counts of total fungi and petroleum degraders in the oilfield wastewater were 4.7±0.46x106 sfu/ml and 59.7±25.7% respectively. Fungal counts in the
tissues of Clarias ranged from 0.20±0.00 x 104sfu/g to 3.00±0.00 x 104sfu/g (skin), 0.48±0.05 x 104sfu/g to 7.25±0.96 x 104sfu/g (gills), and 1.13±0.15 x 104sfu/g to 5.75±0.50 x 104sfu/g (intestine). The intestine had higher fungal counts, but the gills recorded the highest at 10%
concentration. Fungi isolated included; Aspergillus fumigatus (46.43%), Aspergillus niger (100%), Fusarium spp. (100%), Mucor spp. (24.99%), Penicillium spp. (57.14%), Rhizopus spp. (32.13%) and Saccharomyces spp. (34.3%). All except Saccharomyces spp were isolated from oilfield wastewater.
Aspergillus spp. Penicillium spp, Mucor and Rhizopus are considered normal flora, but can still cause infection which may result in the mortality of the fish and eventually economic loss to the aquarium fish industry. Proper treatment of oilfield wastewater prior to discharge into the recipient water body is
advocated to reduce ecotoxicological problems. Get more articles at: http://www.innspub.net/volume-3-number-1-july-2015-ijmm/

It begins with an introduction to the 2014 Toledo water crisis where the water supply was contaminated by a harmful algae bloom producing microcystins. It then discusses cyanobacteria and microcystins, including their properties, biosynthesis, toxicity mechanisms, and health effects in humans and animals. While algae supplements can provide health benefits, concerns are raised about potential microcystin contamination based on detection in some supplements. Stricter quality control and product testing is suggested to ensure safety.
C.9 water pollution n eutrophication
Water pollution occurs when chemicals, biological materials, or physical changes alter water quality and harm living organisms or make water unsuitable for intended uses. Eutrophication is a natural process where an aquatic ecosystem becomes enriched with nutrients, causing excessive growth of plants. Nutrients come from sources like fertilizers, sewage, and runoff. Increased nutrients promote rapid algae growth, which can block sunlight and reduce oxygen levels. This harms ecosystems by eliminating food sources and habitats for aquatic animals.
Higgins
Phosphorus levels are too high in parts of Lake Champlain like Missisquoi Bay, causing harmful algal blooms nearly half the time. These blooms threaten wildlife and limit recreational use. Non-point sources contribute over 90% of excess phosphorus from fertilizers and developed land runoff. Solutions include regulating fertilizer ingredients, intercepting nutrients before they reach waterways, and increasing riparian buffers to filter runoff.
Water monitoring presentation
Monitoring natural waters provides important information about environmental health and human impacts. There are four main methods: visual surveys assess appearance and conditions; biological inventories examine macroinvertebrate diversity and pollution tolerance; water quality tests measure factors like pH, temperature, dissolved oxygen, and contaminants; and flow rate can be monitored. Together these methods generate data for understanding watersheds and informing management decisions.

Water samples from Otamiri River in Imo state, Nigeria, were analyzed based on the afore-mentioned criteria to assess its suitability as a source of water for fish farming. The results of the analysis compared with international standards revealed that the river temperature of 26.90C, nitrate-nitrogen value of 0.015 mg/l and total suspended solids of 18.60 mg/l fall within the acceptable range for fish farming. However, the pH of 5.82, total hardness of 5.8 mg/l, total dissolved solids of 13.60 mg/l and biochemical oxygen demand of 0.6 mg/l all differed slightly from the standard recommended values. This study will aid fish farmers on the necessary treatment needed to effectively use water from this source for fish farming.
Keywords: Water quality criteria, Otamiri River, biochemical oxygen demand, total suspended and total dissolved solids.

Water quality management
Fish depends on water for survival. Without water, aquatic animals ceased to live. It is in this medium that determines their existence, although other factors like food, oxygen also support their growth and survival. Another conditions is the quality of water being supplied. Culture species need good quality water which are free from bacteria. Good water management is necessary to determine fish growth with less mortality

A preliminary study on the toxic potentials of shea butter effluent using Cla...
This study was conducted purposely to evaluate the effects of shea butter effluent (SBE) on the
freshwater inhabitant using Clarias gariepinus as a biological model. A prominent Local factory of shea butter
at Tede, ATISBO Local Government was chosen because the effluent flows directly into a near-by stream that
ends up at a popular Dam in the Local Government on which more than 120,000 people depend for domestic
use.Static bioassay was conducted to determine the LC50 of shea butter effluent to Clarias gariepinus. Ten fishes
each were exposed to 0.05, 0.06, 0.07, 0.08, and 0.09ppt (lethal concentration) of SBE in separate water plastic
bowl of (40cmX29cmX28cm) of 60litres capacity.The lethal Concentration (LC50) value of SBE was 0.057ppt for
96hrs of exposure. Total mortality occurred in the concentrations of 0.08 and 0.09ppt within 24hours of
exposure period. Behavioural reactions exhibited by the fish include erratic movement, air gulping, loss of
reflex, molting, barbell deformation, hemorrhage, and excessive mucus secretion in fish exposed to higher
concentration of shea butter effluent.
The appreciable increase in the mean value of heavy metal, such as Manganese, Nickel, Cadmium,
Zinc, Copper and Lead revealed that the increase in the concentration of shea butter effluent leads to
bioaccumulation of the aforementioned heavy metals in the test organisms. The values for all the metals exceed
the permissible Criteria of the national and international regulatory body. Therefore, Shea butter effluent is
highly toxic to freshwater fishes, its discharged directly into water bodies, new fish farms or in areas close to
aquatic environment should not be encouraged.

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.

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.

Phenomics 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.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
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 debris of the ‘last major merger’ is dynamically young
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.

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.

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.

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.
