The objective of this study is to present methodological tools for characterizing spatial processes of aquifer recharge and discharge, in an approach of multiple scales that contributes to applied contexts of water resources and environmental policies. These methods comprise: rapid assessment of aquifer recharge on local context; spatio-temporal dynamics of land use in the most favorable areas of recharge; cartographic characterization of aquifer recharge; mapping of specific flow of each flow component (quick, inter and base flow); spatial modeling of the influence of the environmental attributes on the flow components. The methods were applied on the Paracatu River Basin, tributary of São Francisco River, in Brazil. The results were interpreted in a cross-scale approach and bring useful information for the sustainable use of water resource and land.

The activities associated to the mining industry are a major source of risk to the environment, but especially for the local community. In Romania, mining of precious metals (gold, silver and copper) have changed the landscape permanently, having a profound impact both locally and regionally. To determine the behavior of the material inside the tailings ponds dams in case of a major seismic event, two ponds were chosen as study cases, both belonging to Rosia Montana mining region: Valea Salistei tailings pond and Gura Rosiei tailings pond. Rosia Montana mining region is one of the most important Romanian mining regions is the Golden Quadrilateral of the Apuseni Mountains, which it delivered over time significant quantities of nonferrous metals, especially gold and silver. For the two study cases the dams' stability was evaluated by classical methods (analytical and numerical), each method using two hypothesis: static and pseudo-static (seismic). The aim of the study is to monitoring the values of the safety factors when the dams of the tailings ponds are affected by an major seismic event and to observe the potential sliding surfaces through the dam's body, the shear deformations distribution and the total displacements and distribution from the resulted graphics on two random sections chosen for each of the case studies.

Aquatic ecosystems are hot spots of most terrestrial biodiversity. They interact with their surrounding terrestrial area through food webs and habitat resources. The aquatic ecosystems also attract a wide range of other fauna including wading and migrating birds, amphibians, riparian mammals and insects. Furthermore, aquatic ecosystems have ability to recycle nutrients of wastewater. Despite many benefits they have, their potentiality in the rehabilitation of quarries is not well recognized. The recent effort on the rehabilitation of quarry site is mostly focused on terrestrial plants despite the fact that quarries life are heterogeneous ecosystems. Owing to this reason, there is a need of using the potential of aquatic ecosystems to enhance the rehabilitation of quarries sites. The present project is therefore focused on establishing the aquatic ecosystem at Wazo hill quarry.
The project won the 1st Prize in National Quarry Life Award in 2014 in Tanzania.

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 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.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.
Monitor common gases, weather parameters, particulates.
BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
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.
Toxic effects of heavy metals : Lead and Arsenicsanjana502982

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).

5. Geological log of Eileen Bore -RSA
In Nossib River (just south of Nossib Rest Camp)
Total T-Qk: 60m
Water strike (1) ±20m
Waterlevel (’61): 21m.
Waterlevel (’86): 41m.
EC: >1000mS/m (TDS: ±7500mg/l);
Yield: 1.6l/s.
The 1961 Deep Aquifer Drilling Programme:
The Eileen Bore is the deepest (381m) of about
four bores drilled by DWA in 1961 to explore the
occurrence of “deep aquifers” in the Gemsbok
Park.
Bores drilled in the northern sector of the park,
intercepted “a whitish sandstone with coal beds”
which was at that time was described as the Auob
Sandstone Member (P.J. Smit, 1964).
Although the water strikes were quite deep, the
aquifer was under pressure (sub-artesian
conditions) and (unfortunately) yielded saline water
(EC: >1600 mS/m).
Yields were in the order of 1.5 to 3l/s. Some of
these bores were still used for game water
supplies, although they used it merely to satisfy
their mineral requirement.
