10. Conclusions On Water Resources
On Earth water has too many forms and variety which
are necessary specifically for particular geographical as well as
environmental surroundings. Below 1% of the world's fresh
water (0.007% of all water on earth) is reachable for direct
human uses. Water pollutions now become a part of concern and
disquiet in country like India. Large parts of water which are life
supportive get contaminated because of illegal activities of human
beings. Water effluence is a major problem globally. It is the
leading worldwide cause of deaths and diseases, and that it
accounts for the deaths of more than 14,000 people daily. In
addition to the acute problems of different problems in
developing countries, industrialized countries continue to
struggle with water pollution problems as well. There are many
inorganic metals which are contaminating water bodies which
serve life to large part of India, Arsenic (As) is one of the biggest
threats for water bodies. High toxicity of Arsenic poses a serious
risk not only to ecological systems but also for human health.
There is availability of sophisticated techniques for arsenic
removal from contaminated water, development of new
laboratory based techniques along with cost reduction and
enhancement of conventional techniques are essential for the
benefit of common people. This paper is based on the future
aspects, for removal of Arsenic from drinking water or the water
of different rivers like Ganga, Gomti and Yamuna etc which
humans are consuming for domestic purpose. Demograph
estimate that around 52 millions peoples are drinking ground
water with arsenic concentrations above the guidelines of World
Health Organization. WHO proposed a parameter or MIC for
Arsenic i.e. of 10 parts per billion (ppb) or 0.010 Mg/L, it is found
that level of Arsenic has been increased vigorously in many
rivers. Objective is to apply Bioremediation technique with the
help of batch culture that needs Bioremediators to detoxify
contaminated water and helps in maintaining the original quality
of water.

Water conservation is the practice of using water efficiently to reduce unnecessary water usage. According to Fresh Water Watch, water conservation is important because fresh clean water is a limited resource, as well as a costly one.
According to the UN report, The population of India expected to surpass China and become the largest country in population size by 2022.
Water-related challenges including water scarcity and water quality deterioration where the pace of urbanization is fastest and the local governments have limited capacity to deal with the rising water supply and sanitation challenges.
Industrial growth is completely related to the addition of a large number of toxic pollutants that are harmful to the environment, hazardous to human health.
Sustainable development (WATER POLLUTION)Abdul Qayum
Safe water and adequate sanitation are indispensable for healthy ecosystems, reducing poverty, and achieving inclusive growth, social well and being and sustainable livelihoods.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

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.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
3. An aquatic ecosystem is an ecosystem in a body water. Communities
of organisms that are dependent on each other and on their environment live
in aquatic ecosystems.
Aquatic ecosystems include oceans, lakes, rivers, streams, estuaries, and
wetlands. Within these aquatic ecosystems are living things that depend on
the water for survival, such as fish, plants, and microorganisms.
These ecosystems are very fragile and can be easily disturbed by pollution.
4. The two main types of aquatic ecosystems are:
1. Marine ecosystems
2. Freshwater ecosystems
There are three basic types of freshwater ecosystems:
• Lentic: slow moving water, including pools, ponds, and lakes.
• Lotic: faster moving water, for example streams and rivers
• Wetlands: areas where the soil is saturated or inundated for at least part
of the time.
5. Aquatic ecosystems contribute to a large proportion of the
planets biotic. Productivity as about 30% of the world's
primary productivity comes from plants living in the ocean.
These ecosystems also include wetlands located at lake shores,
riverbanks, the ocean shoreline, and any habitat where the soil
or vegetation is submerged for some duration. When
compared to terrestrial communities, aquatic communities are
limited abiotically in several different ways.
6. • Organisms in aquatic systems survive
partial to total submergence. Water
submergence influences the availabilityof
atmospheric oxygen, which is requiredfor
respiration, and solar radiation, whichis
neededin photosynthesis.
• Some organisms in aquatic systems must
deal withdissolvedsaltsin their immediate
environment. This condition has caused
these forms of lifeto develop physiological
adaptations to deal withthis problem.
• Aquatic ecosystems are nutritionally limited
by phosphorus and iron, rather than
nitrogen.
7. Water Management is
important since it helps
determine future Irrigation
expectations. Water, once an
abundant natural resource, is
becoming a more valuable
commodity due to droughts
and overuse. It is important
because it is needed for life to
exist. Many uses of water
include agricultural, industrial,
household, recreational and
environmental activities.
Virtually all these human uses
require fresh water.
8. Water is a renewable resource, but only when it’s managed well. If
it isn’t, the world faces serious consequences. Here are ten reasons
why water management matters so much:
1. Our access to water is limited:
Knowing how much water we truly have access to at any given
time is essential to management. Only 3% of the world’s water is
fresh and drinkable.
2. Water management addresses complex issues:
Managing water resources involves a lot of moving parts. The
parties responsible must know how much water is available, how it
needs to be used, and what needs to happen to make the water
usable.
9. 3. Watermanagementtacklesseriouschallenges:
Besides being complicated, water management is difficult. Many
issues put access to clean, safe water in jeopardy.
4. Watermanagementandfoodproductionarelinked:
At 70%, agriculture uses the majority of the world’s freshwater. It’s
needed to produce food, so the more people there are, the more
water is needed.
5. Waterscarcityaffectsover40%of theworld’spopulation:
According to the World Bank, 40% of the world’s population is
affected by water scarcity. Estimates show that by 2025, 1.8 billion
people will live with scarcity.
6. Morethan2 billionpeoplelackreliablewaterservices:
According to a report released by the WHO and UNICEF in 2019,
over 2 billion people lack access to a safely-managed drinking water
service.
10. 7. Poorly-managedwaterresourcesare deadly:
Waterborne illnesses like cholera cause
millions of deaths each year. Children
under the age of 5 who live in developing
countries are especially at risk.
8. Privatizingwatersystems raisesprices:
In recent times, many water systems have
become privatized. This leads to an
increase in prices.
9. Watermanagement is a local andnational issue:
Local authorities are best equipped to
handle top priority issues within a
community. This makes a strong local
water management system essential.
10. Good watermanagement benefitseveryone:
When water resources are managed well,
communities and the government benefit.
11. 1. Human Influences on AquaticEcosystems:
Human activities affecting aquatic ecosystems are more
likely to disrupt natural patterns and processes because
species do not have the ability to adapt to the rapid
changes to their environment that can occur. Human
influences in the lower Athabasca basininclude the oil
sands operations, pulp andpaper mills, municipal
discharges, and, to a lesser extent, forestry and
agriculture.
12. 2. Bioaccumulation and
Biomagnification:
Some contaminants that enter aquaticsystems are
preferentiallystoredin organisms, usually in fat tissue, rather
than being releasedor excreted. This results in an
accumulation of the contaminant over time in a process known
as bioaccumulation. Biomagnificationrefers to the higher
concentrations of contaminants in organisms at higher trophic
levels within food webs. While an organismin a low trophic
level of a food web may contain low levels of a contaminant, its
consumer will concentrate the contaminant as it consumes
manyof theseindividualsover its lifetime. At eachtrophiclevel
in the food web, contaminants become more concentrated.
Contaminantaccumulationis higher in food webs with more
steps to the top predator.
13. Endocrine Disrupting Substances:
Endocrine disrupting substances (EDS) are pollutants that could alter the growth,
reproduction and general development of an aquatic organism. EDSs can be
found in agricultural pesticides, alkyl phenolics (detergents used to remove oils)
found in industrial and municipal effluents, and natural hormones and synthetic
steroids (such as those found in contraceptives) found in municipal effluent and
agricultural runoff.
Climate Change:
Modelling conducted by the Northern Rivers Basin Study (NRBS)
indicated that global climate warming could result in earlier spring melt,
higher levels of rain and snow, and an increase in evaporation (NREI
2002). Together, these changes could result in an overall decrease in
Athabasca River water levels. Warmer temperatures causing earlier
melting of ice jams could affect the replenishment of lakes and ponds,
resulting in lower water levels.
14. Atmospheric Deposition:
Oil sands operations and pulpmills release
gases and small particulate matter (PM)
intothe atmosphere. These substances can
thenbe depositedon the land or water by
dry or wet deposition(whenrainor snow
bind to the gases or particulates).Sulphur
dioxide (SO2) and nitrogendioxide (NO2)
are examples of contaminants foundin the
atmosphere. These gases are associated
withacidrainand the acidificationof
sensitive lakes and soils in the oil sands
region. Mercury is of particular concernin
the northernrivers of Alberta.
15. PROPOSAL PLANS/ MANAGEMENT.
One of the goals of water resource management is water security. It is not possibleto ‘predict and
plan’ a singlepath to water security for rapidlygrowingand urbanizingglobal populations. This
is due to climatic and non-climatic uncertainties. To help strengthen water security, there is a need
to buildcapacity, adaptability and resilience for the future planning and management of water
resources.
Depending on the region and stateof current water conditions, policy and implementation, water
resource management objectives can vary. However, often Water Resources Management objectives
can include promoting conditions for environmentally sustainable, economically efficient and
equitably allocated useof water resources. They also include to increase the benefits and reduce the
risk related to existing hydraulic infrastructure.
16. Levels of planning:
1. Local level:
Plannedfor a small area or village.

Rainwater harvesting technique.
Checkdams, village tanks constructed.
2. Regional level:

19. IMPLICATING THE PLANS.
Integratedaquatic ecosystemmanagement requires proper study, sound
understanding andeffective managementof water systems and their
internal relations. The water systems should be studiedand managedas
part of the broader environment andin relationto socio-economic demands
and potentials, acknowledging the political and cultural context. The aim of
integratedaquatic systemmanagementis to ensure the sustained
multifunctional use of the system.
Sustainable aquatic resources development and management depends
mainly on the proper planning, implementation, operationand
maintenance, which is possible withgeographicinformationsystem(GIS)
and remote sensing techniques, complement and supplement grounddata
collectionin various facets of different kinds of water resources projects.
20. IntegratedWater Resources Management.
1. The concept of integratedwaterresources
management (IWRM) hasbeen developingover the
past several decades. IWRMis the response to the
growingpressure on ourwater resources systems
causedby growingpopulationsand socioeconomic
developments.
2. IWRMis a process whichpromotes the coordinated
development and management of water, land, and
related resources, in order to maximize the resultant
economic and social welfare in an equitable manner
without compromisingthe sustainabilityof vital
ecosystems.
3. Interactionsamong the natural, administrative, and
socioeconomic waterresource subsectors andbetween
themand theirenvironment .
21. Steps involvedin implementation:
Outlining broadpolicygoals as a vision for water
management.
Identifying specific water managementissues and
problems.
Evaluating potential solutions to resolve these issues;
Implementing the most appropriatestrategy(s);
Evaluating the outcomes of implementing these
strategies; and
Integrating the lessons learnedfromevaluating the
outcomes into future work.
The critical stage of this approachis revising future
programs and activities based on past experiences in
waterplanning and management and incorporating
new knowledge and information.
This conceptual model is demonstrated in the
"Learning-by-Doing Management Cycle" below.
22. Top-Down Planning and Management.
1. These plans typically consist of a series of reports, complete with numerous appendices, describing all aspects of water
resources management anduse.
2. This master planning exercise has typically been a top-downapproach. Professionals have dominatedthe top-down
approach.
3. Using this approach there is typically little if any active participationof interestedstakeholders. The approach
assumes that one or more institutions have the ability and authority to develop and implement the plan.
Bottom-Up Planning and Management.
1. Plans are being created from the bottom-up rather than top-down through a process of consensus building.
Concerned citizens, nongovernmental organizations, as well as professionals in governmental agencies are
increasingly working together toward the creation of adaptive comprehensive water management programs,
policies, and plans.
2. Bottom-up planning must strive to achieve a common or “shared” vision among all stakeholders. It must either
comply with all applicable laws and regulations or propose changes to them.
3. These process issues emphasize the need to make water resources planning and management as efficient and
effective as possible and remain participatory.
23. Water Management Techniques
Following are the top 10 water best management practices that are implementedto reduce water
use: 1. Meter/Measure/Manage
2. Optimize Cooling Towers
3. Replace RestroomFixtures
4. EliminateSingle-Pass Cooling
5. Use Water-Smart Landscapingand Irrigation
6. Reduce SteamSterilizer Tempering WaterUse
7. Reuse Laboratory Culture Water
8. Control Reverse Osmosis SystemOperation
9. Recover Rainwater
10.Recover Air Handler Condensate
24. CONCLUSION.
Effective water resources planning, and management is a challenge today, and
will be an increasing challenge into the foreseeable future. This presentation
introduces some of the tools that are being used to meet these challenges. We
consider it only a first step toward becoming an accomplished planner or
manager.
