Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.[2] Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural (off-grid) energy services.
Based on REN21's 2014 report, renewables contributed 19 percent to our global energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% is electricity from wind, solar, geothermal, and biomass. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

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.
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.
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.

2. Energies Sources
(Sources of Fuel )
A
Presentation

Mr. Allah Dad Khan
Agriculture Free Lance
Consultant and Adviser KPK
Pakistan
3. 1) Characteristics of a good source of fuel :-
i) It should have a high energy output per unit mass or volume.
ii) It should be easily available.
iii) It should be easy to store and transport.
iv) It should be economical.
2) Sources of energy :-
There are two main sources of energy. They are conventional and
non conventional sources of energy.
i) Conventional sources of energy :- are wood, flowing water
and fossil fuels (coal, petroleum, natural gas).
ii) Non conventional sources of energy :- are solar energy, wind
energy, biomass energy, ocean energy (tidal energy, wave energy,
ocean thermal energy), geothermal energy, nuclear energy etc.
Some sources of energy are renewable like sun, wind, flowing
water, ocean, wood, biomass etc.
Some sources of energy are non renewable like coal, petroleum and
natural gas.
4. 3. Conventional sources of energy :-
a) Fossil fuels :- are fuels formed inside the earth from the
remains of plants and animals after millions of years. The
fossil fuels are coal, petroleum and natural gas. Fossil
fuels are non renewable sources of energy so they
should be conserved and used judiciously.
Disadvantages of fossil fuels :-
i) Burning of fossil fuels release gases and harmful
particles which causes air pollution.
ii) Burning of fossil fuels release acidic oxides of sulphur
and nitrogen which causes acid rain which is harmful for
living organisms, affects soil and water, causes damage
to buildings, corrosion of metals etc.
iii) Burning of fossil fuels release a large amount of carbon
dioxide gas which increases the temperature of the
atmosphere and causes global warming (green house
effect).
5.
6. b) Thermal power plants :-
In thermal power plants the heat energy produced by burning fossil
fuels like coal, petroleum or natural gas is used to heat water and
change it into steam which rotates the turbines of generators to produce
electricity.
c) Hydro power plants :-
In hydro power plants water from rivers are stored by constructing
dams. The water from the dam flows down through pipes and rotates
the turbines of generators to produce electricity.
Advantages :-
i) Flowing water is a renewable source of energy.
ii) The electricity produced does not cause pollution.
iii) The water stored in dams can also be used to control floods and
for irrigation.
Disadvantages :-
i) The initial cost is high.
ii) Large areas of land gets submerged and the decomposition of
vegetation produces methane gas which is a green house gas.
iii) It causes displacement of people from large areas of land.
9. d) Biomass energy :-
The waste materials and dead parts of living things are
called biomass. Eg :- wood, animal dung, vegetable waste,
agricultural waste, sewage etc. Biomass is decomposed
by anaerobic microorganisms to produce biogas.
Biogas is a mixture of gases containing methane, carbon
dioxide, hydrogen and hydrogen sulphide.
Biogas plant :-
The biogas plant has a large underground tank made of bricks and
cement. The lower part is the digester and the upper part has a dome
with a gas outlet. On one side of the tank above the ground is a mixing
tank and on the other side is an overflow tank.
Animal dung is mixed with water in the mixing tank and the slurry is
sent into the digester. In the digester the slurry is decomposed by
anaerobic microorganisms and after a few days biogas is produced.
The gas is taken out through the gas outlet and used for heating and
lighting purposes. The slurry left behind is rich in nitrogen and
phosphorus and is used as manure for crops.
11. e) Wind energy :-
Wind energy is used in wind mills which converts the
kinetic energy of the wind into mechanical or electrical
energy. The kinetic energy of wind can be used to do
mechanical work like lifting water from wells or grinding
grains in flour mills. It can also be used to rotate the
turbines of generators to produce electricity.
A single wind mill produces only a small amount of
electricity. So a large number of wind mills in a large area
are coupled together to produce more electricity in wind
energy farms.
Advantages :-
i) It is a renewable source of energy.
ii) It does not cause pollution.
iii) The recurring cost is less.
Disadvantages :-
i) Wind is not available at all times.
ii) It requires a large area of land.
iii) A minimum wind speed of 15 km/h is required.
13. 4) Non conventional sources of energy :-
a) Solar energy :-
Solar energy is the energy obtained from the sun in the form of heat
and light. The heat energy is used in solar heating devices like solar
cooker, solar water heater, solar furnaces etc. The light energy is used
in solar cells.
i) Solar cooker :-
The box type solar cooker has an insulated box painted black inside.
It is covered by a glass plate which allows heat to enter inside but does
not allow heat to escape out. It has a mirror to reflect more sunlight into
the box. The food to be cooked is kept in containers inside the box It
can produce a temperature of 100° to 140°.
ii) Solar water heater :-
A solar water heater has an insulated box painted black inside with a
system of copper tubes. It is covered with a glass plate which allows
heat to enter inside but does not allow heat to escape out. When water
flows through the copper tube it absorbs heat and becomes hot.
14. iii) Solar cells :-
Solar cell is a device which converts solar energy into electrical
energy. Solar cells are made from semi conductors like silicon,
germanium, gallium etc. A single solar cell produces a voltage of about
0.5 to 1 V and produces about 0.7 W electricity. So several solar cells
are arranged in a solar panel to produce more electricity.
Advantages :-
i) It uses renewable source of energy.
ii) It produces electricity which does not cause pollution.
iii) It can be used in remote areas where there is no power supply.
Disadvantages :-
i) It uses a special grade of silicon which is expensive.
ii) Since silver is used for connecting the cells together it is more
expensive.
iii) The current produced is DC and to convert it to AC increases the
cost.
18. b) Energy from the sea :-
Energy from the sea is obtained in three different forms. They are
Tidal energy, Sea wave energy and Ocean thermal energy.
i) Tidal energy :-
The periodic rise and fall of sea level due to gravitational attraction
of the moon causes tides. A dam is constructed at a narrow opening
between the land and sea. The movement of water during high tide and
low tide can be used to rotate the turbines of generators to produce
electricity.
ii) Sea wave energy :-
When strong wind blows over the sea it produces huge waves. The
kinetic energy of the moving waves can be used to rotate the turbines
of generators to produce electricity.
iii) Ocean thermal energy :-
There is a temperature difference between the warm surface water
and the cold water at the bottom of the oceans. This difference is about
20°C. The warm surface water is used to boil liquid ammonia and the
vapour is used to rotate the turbines of generators to produce
electricity. The cold water from the bottom is then pumped up to cool
the vapour back to liquid.
22. c) Geothermal energy :-
The deeper regions of the earth’s crust is very hot. This heat melts
rocks and forms magma. The magma moves up and collects below at
some places called Hot spots. The underground water in contact with
hot spot gets heated into steam at high pressure. By drilling holes into
hot spots the steam coming out can be used to rotate turbines of
generators to produce electricity.
24. d) Nuclear energy :-
Nuclear energy is the energy is the energy released during nuclear reactions.
During nuclear reactions some mass is converted into energy and so a very
large amount of energy is produced during nuclear reactions.
Nuclear reactions are of two types. They are Nuclear fission and nuclear fusion.
i) Nuclear fission :- is a nuclear reaction in which the nucleus of a heavy atom
like uranium, plutonium, etc. splits into smaller nuclei with the release of a large
amount of energy. It is used to make atom bombs and to produce electricity.
In a nuclear power plant the heat energy produced by a controlled nuclear
fission chain reaction is used to produce steam which rotates the turbines of
generators to produce electricity.
ii) Nuclear fusion :- is a nuclear reaction in which small nuclei fuse together to
form a heavier nucleus with the release of a very large amount of energy. The
energy of sun is produced by the fusion of hydrogen nuclei to form helium
nucleus. It is also used to make the hydrogen bomb.
Advantages of nuclear energy :-
i) It produces a very large amount of energy per unit mass than any other
source of energy.
ii) If safety measures are taken, it is more environment friendly than fossil fuels.
Disadvantages of nuclear energy :-
i) The cost of a nuclear reactor is very high.
ii) The availability of nuclear fuel is limited.
iii) Nuclear reactors produce harmful nuclear wastes which is difficult to
dispose.
