Alkaline Soils and it’s Improvement in Panchganga Basin (Maharashtra): A Geog...Malhari Survase
The use of land without consideration its limits will result in disturbing soil from its natural or ideal state. Both the physical and chemical properties of soil can be totally or partly altered due to human interference. The economic man always tries to achieve maximum economic gain without consideration of potential problems. These results gradually in deteriorating soil quality. The aims of this paper are to understand distribution, severity and estimating extent of chemically degraded alkaline soils which affect directly on the capacity of soil and environment in the region and suggest suitable conservation measures. The selected region for the present investigation is the 'Panchaganga Basin' of south Maharashtra state comprising 7 tahsils of Kolhapur district, Maharashtra. For the present investigation,both primary and secondary sources are used for this paper. Data regarding different properties of soil and water is collected from Government Soil Survey and Soil Testing Laboratory, Kolhapur and other through field work. Soil analysis has been done and chemical properties of soils are represented by choropleth methods. For this purpose special soil sample data is used. Area of alkali soil is identified with the help of soil chemical and physical properties. Simultaneously field observation and village wise obtained data has been supported. In the study region 46.72% area has covered by alkaline soil. Out of that 31.96% are slightly alkaline and 14.76% are strongly alkaline. Most of the eastern tahsils such as Shirol (94.59%), Hatkanangle (83.33%), Panhala (52.94%) and eastern part of Karveer (45.28%) tahsils have above 40% areas under alkaline soils. As per the risk of alkalinity, the physical, chemical and agronomic measures suggested for the improvement of alkaline soils.

A presentation to a meeting of the Riverina branch of Soil Science Australia on 31 Aug 2018 by Sam North, NSW DPI, Deniliquin. CSIRO conducted soil surveys in the Deniboota Irrigation District in 1942 for soil mapping purposes prior to the introduction of irrigation. A small number of these sites were were re-sampled in 2017, with paired sites (irrigated & dryland) found on each soil type sampled. The results of the chemical analysis of the 2017 samples is compared with that from the 1942 survey. The major change appears to have been leaching of soluble salts (chloride) from both irrigated and dryland sites. It is postulated this is due to a wet period between 1950 and 1990.

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.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

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).
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.

Editor's Notes
Now, let’s have a look at the long-term field results. I have put a figure containing four exchangeable cation accumulation in three soil layers: 0 – 10 cm, 10 – 30 cm, and 30 – 60 cm. The red dashline represents the change from BIL water to NPEC treated winery wastewater since 2010. I’ve circled one of deeper layers as an example. For exchangeable K accumulation, you can see K remained stable before the switch to NPEC, but increased gradually with time after the switch. The change of exchangeable Mg generally reduced with time before the switch, but an reduction observed after the switch. The change of exchangeable Na had little increase between 2007 and 2009, and presents a slight reduction after the switch. The change of exchangeable Ca is steady, only little alteration observed.
The EC values of all soil layers in this site are lower than 0.5 dS/m, so no salinity problem exists in this site.
RBEs: a pH of between 5.0 and 6.5. The topsoils of red brown earths are usually non-sodic, and relatively low in clay content. The subsoils are generally sodic and higher in clay content. This means that water penetration of the subsoil is low. Therefore a ‘perched’ watertable can form above the subsoils of red brown earths. Since water penetration of the topsoil is generally good, the deeper the topsoil the more water can be stored at each irrigation.
Electronic turbidity meters work by measuring the amount of light which is scattered at 90° by the suspended particles. This scattering does vary slightly with the size of the particles – large particles may be more prone to scatter light at smaller angles, while small particles will allow light to scatter at larger angles;
