Energy can exist in various forms and can be converted from one to another, but cannot be created or destroyed. There are two main types of energy: renewable and non-renewable. Renewable energy sources include solar, wind, geothermal, and hydroelectric, which can be naturally replenished. Non-renewable sources like petroleum, coal, and uranium are finite and cannot be easily replenished. Both renewable and non-renewable energy sources have advantages like providing power, but also disadvantages such as high costs, environmental pollution, and long-term waste issues.

Renewable and Non- renewable energy SourcesGeorge Thomas
Renewable energy is energy which is generated from natural sources i.e. sun, wind, rain, tides and can be generated again and again as and when required. Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and will vanish fifty-sixty years from now.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
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.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
(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.
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.

Sources of energy renewable and non-renewable
1.
2. What is energy?
Energy can neither be
created nor it can be
destroyed. It can only
be converted from one
form to another.
3. Types of Energy
Energy can be broadly
divided into two
categories-
Renewable energy
Non-renewable energy
4. Renewable Energy
Renewable energy can be
generated continuously
practically without decay
of source. E.g. –
Solar energy
Wind energy
Geothermal energy
Hydroelectric energy
5.
6. Solar Energy
Solar energy, radiant light and heat
from the sun, has been harnessed
by humans using various
equipments.
Advantages
Solar energy doesn’t produce
Carbon dioxide.
Disadvantages
It is not constant, it depends on
weather conditions, time,location.
8. wind energy generated by wind
turbines is mainly used to generate
electricity.
Advantages :
Wind turbines (often called windmills)
do not release emissions that pollute the
air or water.
Disadvantages :
Installation and maintenance cost is very
high.
Only few places are there in world
where wind blow continuously
throughout the year.
10. Geothermal Energy
Geothermal energy is heat from within
the Earth. We can recover this heat as
steam or hot water and use it to heat
buildings or generate electricity.
Advantages :
carbon dioxide emission levels are very
low. They release less than 1% of the
carbon dioxide.
Disadvantages :
Installation cost is very high.
Release various kind of harmful gases.
12. Hydroelectric Energy
Hydro energy is generally
generated form running water
using various mechanical methods.
Advantages :
Produces very less amount of
carbon dioxide.
It is also being used to control
flood and for irrigation purposes.
Disadvantages:
Natural environment is destroyed.
16. Non renewable energy can’t
be generated again and
again form the same source.
E.g. –
Petroleum products
(kerosene,petrol,diesel,etc )
Coal
Uranium
17. Petroleum(oil)
Oil was formed from the remains of
animals and plants that lived millions of
years ago in a marine (water)
environment before the dinosaurs.
Over millions of years, the remains of
these animals and plants were covered
by layers of sand and silt
Disadvantages :
Responsible for 38% of carbon
dioxide in the environment
18.
19. Coal is a combustible black or
brownish-black sedimentary
rock composed mostly of
carbon and hydrocarbons.
Disadvantages :
Responsible for 57% of
carbon dioxide in the air.
20.
21. uranium
Nuclear energy is energy in the
nucleus (core) of an uranium-235
atom. Atoms are tiny particles that
make up every object in the
universe.
It can be released from atoms in two
ways: nuclear fusion and nuclear
fission.
22. Advantages :
Even a small amount can release
enough energy to light-up
thousand of energy for months. (1
kg uranium-235 corresponds to
2.7 million kg coal equivalent.)
Disadvantages
After using it in nuclear reactor
then also it radioactive substances
is very dangerous for human . Eg :
carbonyl accident and fukushima
plant accident.
