Water is essential for all life of forms on earth-including human, animal and vegetation.
It is therefore important that adequate supplies of water be developed to sustain such life
Where there is no surface water, where groundwater is deep or inaccessible due to hard ground conditions, or where it is too salty, acidic or otherwise unpleasant or unfit to drink, another source must be sought.
In areas that have regular rainfall, the most appropriate alternative is the collection of rainwater, called rainwater harvesting .
Water is a very important resource in our life . The availability of water resources on earth are limited and unevenly distributed. Human demand for water has been growing for two reasons. The available water is to be conserved. This module explains the major practices adopted in water conservation.

Factors such as population growth, climate change, and over-extraction of groundwater have placed a strain on access to clean water. In response, rainwater harvesting emerges as a sustainable solution to address these pressing water challenges. This blog explores the concept of rainwater harvesting, delves into its significance, methods, and its pivotal role in promoting water sustainability.
E-content is a Comprehensive package of teaching material put into hypermedia format. Hypermedia is multimedia with internet deplorability. E-content can not be created by a teaching faculty alone . It needs the role of teacher, Video editor, production assistants, web developers (HTML 5 or Adobe captivate, etc). Analyze the learner needs and goals of the instructional material development, development of a delivery system and content, pilot study of the material developed, implementation, evaluating, refining the materials etc. In designing and development of E-content we have to adopt one of the instructional design models based on our requirements.
Pedagogy is the most commonly understood approach to teaching. It refers to the theory and practice of learning. Pedagogy is often described as the act of teaching. Pedagogy has little variations between traditional teaching and online teaching. Online teaching pedagogy is a method of effective teaching practice specifically developed for teaching via the internet. It has a set of prescribed methods, strategies, and practices for teaching academic subjects in an online (or blended) environment, where students are in a physical location separate from the faculty member.
Technology has changed the possibilities within teaching and learning. Classes, which prior to the digital era were restricted to lectures, talks, and physical objects, no longer have to be designed in that manner. Training in a synchronous virtual classroom can only be successful with the active participation and engagement of the learners. Explore the Virtual Classroom’s features and see how they can support and enhance your tutoring style.

Climate Extreme (extreme weather or climate event) refers to the occurrence of a value of a weather or climate variable above (or below) a threshold value near the upper (or lower) ends of the range of observed values of the variable. Extreme weather and climate events, interacting with exposed and vulnerable human and natural systems, can lead to disasters.
WATER RESOURCES PLANNING AND MANAGEMENT POSSIBILITIES IN CHAMARAJANAGAR TALUK...Prof. A.Balasubramanian
Any unplanned development and utilization of water resources with result in water scarcity. In many parts of the developing world. Such a situation exists. In order to do proper planning and
management of water resources, it is necessary to conduct detailed analyses of the factors, which influence the water availability and its uses. In the present study, a comprehensive analysis have been undertaken for proper utilization of water resources in Chamarajanagar Taluk, which has been identified as one of the drought hit districts of Karnataka, in India. The factors analysed in this work are, surface and groundwater availability, land use, cropping pattern, recharge potential of soils and the rainfall pattern in typical areas of Taluk. It is observed that the problem of water scarcity is mainly due to the lack of irrigation planning and management. Hence, a
modified cropping pattern is suggested by taking into consideration of all available water resources and other conditions.
In broad terms, cultural geography examines the cultural values, practices, discursive and material expressions and artefacts of people, the cultural diversity and plurality of society.
It also emphasizes on how cultures are distributed over space, how places and identities are produced, how people make sense of places and build senses of place, and how people produce and communicate knowledge and meaning.
Minerals are formed by changes in chemical energy in systems which contain one fluid or vapor phase. In nature, minerals are formed by crystallisation or precipitation from concentrated solutions. These solutions are called as ore-bearing fluids. Ore-bearing fluids are characterised by high concentration of certain metallic or other elements.
Fluids are the most effective agents for the transport of material in the mantle and the Earth's crust.
Soils are complex mixers forming the skin of the earth's surface. Soil is a dynamic layer in which many complex chemical, physical and biological activities are going on constantly. Soils become adjusted to conditions of climate, landform and vegetation, and will change internally when those controlling conditions change. Soils are products of weathering. Soils play a dominant role in earth's geomorphic processes in a cyclic manner. The characteristics of soils are very essential for several reasons. This module highlights these characteristics.
GIS TECHNIQUES IN WATER RESOURCES PLANNING AND MANAGEMENT IN CHAMARAJANAGAR ...Prof. A.Balasubramanian
The over-exploitation and contamination of groundwater continue to threaten the long-term sustainability of our precious water resources, in spite of the best efforts made by various agencies.
This has many serious implications to the economic development of a country like India. Lack of
judicious planning and integration of environmental consideration to ground water development
projects are primarily responsible for such a state of affair in the ground water sector. Geographical Information Systems could be of immense help in planning sustainable ground water management strategies, especially in hard rock areas with limited ground water potential. Data collected from
Satellite Imagery and through field investigations have been integrated, on a GIS platform, for demarcation and prioritization of areas suitable for ground water development and ground water augmentation. An attempt has also been made to assess the vulnerability of the area to ground water
contamination. This paper demonstrates the utility of GIS in planning judicious management of ground water resources in a typical hard rock area of Chamarajanagar Taluk, Karnataka, state India.
Nanobiomaterials are very effective components for several biomedical and pharmaceutical studies. Among the metallic, organic, ceramic and polymeric nanomaterials, metallic nanomaterials have shown certain prominent biomedical applications. Enormous works have been done to synthesize, analyse and administer the metallic nanoparticles for various kinds of medical and therapeutic applications, during the last forty years. In these analyses, the prominent biomedical applications of ten metallic nanobiomaterials have been reviewed from various sources and works. It has been found that almost nine of them are used in a very wide spectrum of medical and theranostic applications.

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.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
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.

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.

Prof. A. Balasubramanian
Dept. of Studies in Earth Science
University of Mysore
Mysore, India
2. 2
Introduction:
Water is a very important resource in our life.
Water is becoming scarce due to increase in Population,
industries and agricultural activities and due to poor rainfall.
A report of 2009 suggested that by 2030, in some developing
regions of the world, water demand will exceed supply by
50%.
Water plays an important role in the world economy, as it
functions as a solvent for a wide variety of chemical
substances and facilitates industrial cooling and
transportation.
3. 3
Goals of Water Conservation
1) Sustainability: To ensure availability for future
generations, the withdrawal of fresh water from an ecosystem
should not exceed its natural replacement rate.
2) Energy conservation: Water pumping, delivery, and
wastewater treatment facilities consume a significant amount
of energy. In some regions of the world over 15% of total
electricity consumption is devoted to water management.
3) Habitat conservation: Minimizing human water use helps
to preserve fresh water habitats for local wildlife and
migrating water flow, as well as reducing the need to build
new dams and other water diversion infrastructure.
4. 4
Water harvesting and conservation
Water conservation refers to reducing the usage of water and
recycling of waste water for different purposes like domestic
usage, industries, agriculture etc.
Methods of Water Conservation:
1. Protection of Water from Pollution;
2. Redistribution of Water
3. Rational Use of Groundwater
4. Renovation of Traditional Water Sources
5. Use of Modern Irrigation Methods
5. 5
6. Increasing Forest Cover
7. Change in Crop Pattern
8. Flood Management
9. Conserving Water in Industries
10. Conservation of water by Municipal authorities
11. Use rainwater effectively
12. Make effective use of soil water reserves
13. Take measures to avoid run off
14. Avoid wasting water through evaporation
15. Reduce water losses through drainage
16. Plan your irrigation

Rainwater Harvesting
Rainwater Harvesting is an effective method and a
simple method of collecting water for future usage. Rainwater
harvesting is the process of collecting, filtering, storing and
using rainwater for irrigation and for various other purposes.
Rainwater is collected when it falls on the earth, stored and
utilized for various purposes. It can be purified to make it into
a drinking water facility in some islands and dry land regions.
Rainwater harvesting (RWH) is a simple method by which rainfall is
collected for future usage. The collected rainwater may be
stored, utilised in different ways or directly used for recharge
purposes.
14. 14
Benefits of Rainwater Harvesting
Rainwater harvesting has many benefits. The major benefit is
that it is a sustainable water management practice. It can be
implemented by every citizen at various levels. It is a
socially acceptable practice and promotes environmentally
responsible future.
The rainwater that falls on any roof and property is
essentially free. All it needs is to adopt a method to harvest
it and store it in a tank or cistern for future use.
Rainwater harvesting helps to reduce the peak demand of
water expected during summer period, by saving treated
water for more important water uses.
15. 15
While rainwater can be a perfect primary water source for
many uses and situations, it is would be a good backup water
supply for emergency situations.
The Environmental Benefits
Rainwater harvesting can reduce storm-water runoff and
wastage from any land. The reduction in runoff volume can
reduce the level of contamination of surface water resources
with pesticides, solid wastes, municipal effluents, sediments,
metals, and fertilizers.
By reducing the storm-water runoff, rainwater harvesting can
reduce the flow volume and velocity in local streams, and
rivers. This also help to avoid the potential for erosion along
river beds.
16. 16
Rainwater harvesting systems can be an excellent source of
water for growing plants and carry out landscape irrigation.
The Economic Benefits
Collecting and using rainwater, in place of municipal water
supply, reduces the water bill to some extent. This also
reduces the water service cost to a municipality, for their
people.
Rainwater harvesting can reduce water demand from
municipalities. It helps to provide potable water at a lower
cost. Designing and installing rainwater collection systems
can provide sustainable jobs for people and help to earn more.
17. 17
The rainwater harvesting industry can become a leading
employer in the green infrastructure movement. Rainwater
stored onsite in a rainwater harvesting system can avoid
increasing forest fires.
Insurance companies can offer better discounts for those who
implement better water management practices.
Miscellaneous Benefits
Rainwater doesn’t have the any chemicals in it. Rainwater
can be used for irrigation. It is a suitable potable water
source. Rainwater harvesting can provide an independent
water source in areas where other water sources are not
available.
18. 18
In some places where the water quality is poor, we may use
rainwater, safely.
Good rainwater provides many advantages.
Rainwater harvesting is the key to the future water
conservation gains.
Rainwater harvesting is a vital resource for the future of
sustainable water resources. Reduce demand on Ground
Water.
19. 19
Rainwater harvesting is part of a sustainable water supply strategy
for local communities.
Rainwater for Non-drinking Purposes:
Rainwater can be used for several non-drinking purposes like flushing
toilets, washing clothes, watering the garden, washing cars etc. It is a
unhealthy practice to use pure drinking water some other purposes other
than drinking.
Disadvantages of Rainwater Harvesting
Rainfall is unpredictable. There is an Initial Cost for
establishment.
Rainwater harvesting systems require regular maintenance.
20. 20
There are limitations in storage tank capacities.
Techniques of Rainwater Harvesting
Rooftop rainwater harvesting (RTRWH) is the most common
technique of rainwater harvesting (RWH) for domestic
consumption. In urban and rural areas, this is most often
practiced method at a small-scale. It is a simple, low-cost
technique that requires minimum specific expertise or
knowledge.
21. 21
Rainwater is collected from the roof top and transported with
gutters in to a storage reservoir, where it provides water at the
point of consumption or can be used for recharging a well or
the aquifer.
Collected rainwater can be the best supplement to other water
sources when they become scarce or are of low quality like
brackish water, saline groundwater or polluted surface water,
in the rainy season.
The technology is flexible and adaptable to a very wide
variety of geographic and geomorphic conditions. It is used in
the developed and the developing societies.
22. 22
Roof Top Rain Water Harvesting
Basic design principles
Each rainwater harvesting system consists of at least the
following components:
A catchment area in the roof surface to collect rainwater.
A delivery channel (gutters) to transport the water from the
roof or collection surface to the storage reservoir.
Storage tanks or reservoirs to store the water until it is used.
An extraction device (depending on the location of the tank).
25. 25
Factors to be considered
Type and size of catchment area
Local rainfall data and weather patterns
Length of the drought period
Alternative water sources
Cost of the rainwater harvesting system.
When rainwater harvesting is mainly considered for
irrigation, several factors should be taken into
consideration. These include: Rainfall amounts,
intensities, and evapo-transpiration rates. Soil infiltration
rate, water holding capacity, fertility and depth of soil .
Crop characteristics such as water requirement and length
of growing period .
26. 26
Hydrogeology of the site .
The Basic Calculation
Roof top flat area:
4m by 5m = 20 Sq.m
total annual total annual rainfall in mm = 500 mm
efficiency factor / runoff coefficient = 0.9
Annual water supply in liters = 20 x 500 x 0.9 = 9000 liters
27. 27
Rainwater Collection
Calculation Formulas and Equations
Roof Area (ft2) X Precipitation Amount (in) X 0.623 =
Amount Collected (gallons)
How to choose the size of the storage tank:
A house with a roof area of 9.00 x 6.50 m is to be furnished
with catchment and storage facilities. The mean annual
rainfall is 450 mm.
Calculation of rainwater:
9.00 x 6.50 x 450 x 0.9 = 23895 litres

Tamil Nadu:
Tamil Nadu was the first state to make rainwater harvesting
compulsory for every building to avoid groundwater
depletion. The scheme was launched in 2001 and has been
implemented in all rural areas of Tamil Nadu.
Karnataka -World’s largest rainwater harvesting project:
The World’s largest rainwater harvesting project was carried
out in Karnataka.
Rainwater harvesting in rural Karnataka’ funded by Rural
Development and Panchayat Raj Department (RDPR),
Government of Karnataka is probably the largest rainwater
29. 29
harvesting project in the world. All the schools of Karnataka
were carefully studied for the water availability, quality
(fluoride contamination) and proximity to the secondary
water source.
Almost 23,683 schools were identified in the first phase to
provide drinking water through rooftop rainwater harvesting
systems.
Steps taken by the Central Government to promote rain water
harvesting in the country are as follows:
1. Central Ground Water Board (CGWB). Govt of India,
has prepared a conceptual document titled “Master Plan for
Artificial Recharge to Ground Water – 2013.
30. 30
2. The National Water Policy (2012) formulated by Ministry
of Water Resources, RD & GR, inter-alia, advocates
conservation, promotion and protection of water and
highlights the need for augmenting the availability of water
through rain water harvesting, direct use of rainfall and other
management measures.
3. CGWA( Water Authority) has issued advisories to States
and UTs to take measures to promote/adopt artificial recharge
to ground water/rainwater harvesting. 30 States/UTs have
made rainwater harvesting mandatory by enacting laws or by
formulating rules & regulations or by including provisions in
building bye-laws or through suitable Government Orders.
31. 31
4. CGWB has taken up Aquifer Mapping and Management
programme (NAQUIM) during XII Plan, under the scheme of
Ground Water Management and Regulation.
5. Model Building Bye Laws, 2016 circulated by Ministry of
Urban Development include the provision of Rainwater
Harvesting. As per Model Building Bye Laws, water
harvesting through storing of water runoff including rainwater
in all new buildings on plots of 100 sq.m and above will be
mandatory.
6. The Ministry of Rural Development in consultation and
agreement with the Ministry of Water Resources, RD & GR
and the Ministry of Agriculture & Farmers’ Welfare has
developed an actionable framework for Natural Resources
32. 32
Management (NRM), titled “Mission Water Conservation” to
ensure gainful utilization of funds.
Types of common works undertaken under these
programmes/schemes are water conservation and
management, water harvesting, soil and moisture
conservation, groundwater recharge, flood protection, land
development, Command Area Development & Watershed
Management.
The government of India is working on a master plan
envisaging construction of about 23 lakh artificial recharge
and rainwater harvesting structure in rural areas and 88 lakh
in urban areas, as informed in the Lok Sabha, already.

Conclusion:
In many cases, groundwater or surface water may be
unavailable for drinking water. The groundwater level may be
too deep, groundwater may be contaminated with minerals
and chemicals such as arsenic or salt, surface water may be
contaminated with faeces or chemicals. In these cases,
rainwater harvesting can be an effective and low-cost
solution.
