Each organism in this world, whether it is a plant, an animal or a microorganism, is unique in itself. This uniqueness of individuals forms the basis of the diversity among the living organisms.
This presentation explores diversity in organisms. How are they classified and how are they studied.
threats to biodiversity, conservation of aquatic biodiversity, conservation of terrestrial biodiversity, what is biodiversity, biodiversity of India, conservation of biodiversity
If you look around you will see a large variety of living organisms, be itpotted plants, insects, birds, your pets or other animals and plants. Thereare also several organisms that you cannot see with your naked eye butthey are all around you.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
Toxic effects of heavy metals : Lead and Arsenicsanjana502982
Heavy metals are naturally occuring metallic chemical elements that have relatively high density, and are toxic at even low concentrations. All toxic metals are termed as heavy metals irrespective of their atomic mass and density, eg. arsenic, lead, mercury, cadmium, thallium, chromium, etc.
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.
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.
Richard's aventures in two entangled wonderlandsRichard 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.
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.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.
Monitor common gases, weather parameters, particulates.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

BIOLOGYGROUP PRESENTATION
2.
3. Today ,Earth is the only known place to us
where life really exists. But this planet is so
favorable in supporting life , that there has
born an extremely huge, huge, huge,
biodiversity. And this really does mean huge.
Till today, scientists have only found over a
million organisms , while it is supposed that
over 30 million of them are still hidden. To
know our existence , we have to know about
existence of universe. Before that we have to
know Earth and finally for it, all organisms are
to be known.
4. Images of all the organisms on Earth. To fit all of them , every
image has became so small that they have become a single dot
only. Now maybe , you can understand the meaning of
biodiversity , that also just on Earth. The whole universe (with
over 30 m. organisms) is still left . To completely understand
the above picture , the way of classification can only help us.
That’s why CLASSIFICATION is very, very, very, very, important
to satisfy our curiosity.
5. Now you can suppose how much time it
will take for the whole process . And
Time is Precious. That's why scientists
have discovered the shortest way of this
- “Classification” , which simply means ,
grouping organisms into categories and
study them together.
6. What is Classification?
The scientific practice of
identifying, naming and grouping
living organisms is called
“CLASSIFICATION”
The branch of Biology ,that deals
with the classification of
organism is called “TAXONOMY”
7.
8. It makes the study of living organisms
convenient.
It helps in the specific identification of any
given organism.
It provides information about plants and
animals, which occur in specific geographical
regions.
Systematic study can help in exploring
unknown potential of many helpful organisms.
Taking help from these potential can help us in
restoring the ecosystem, which has got
imbalanced today.
9.
10. Knowing more organisms can inspire
engineering more.
It can give an idea about the evolution of
past 3.5 billion years and also of the
future evolution.
It reveals the relationships among various
groups of organisms. Some natural cycles
or chains can also be related by this.
We only get the fossils of extinct species.
But seeing the relationship of evolution
and organisms can give an idea about their
structure.
11.
12. FIRST BASIS : Whether the organism was
beneficial or harmful to humans . But
it mixed plants and animals both ,
which is improper ,like
18. fourth BASIS : This one was the most accurate
basis, which was given by Robert
Whittaker, Earnest Haeckel and Carl
Woese . It is this,
19. Basis of classification , used today :
The presence or absence of a nuclear
membrane , i.e., Prokaryotic (Primitives)
or Eukaryotic (Complex ones).
22. The type of nutrition used by the
organism (i.e., Heterotrophic or
Autotrophic).
23. Finally Phylogenic Relationships and Body
Design.
Evolved
from me.
Aren’t you?
Yeah. You’re
Quite

24.
25.
26. MONERA
Prokaryotic
Unicellular , some exists in clusters
Mostly Heterotrophic , except Blue-Green Algae
Has Cell Wall and is the most primitive
organism on earth
34. How it works?
After classifying all organisms into biggest group
KINGDOM , they are further separated into
groups again inside the kingdom itself , which
has the basis of many factors like complexity
or others , depending upon the type of
kingdom and the organisms taken in it. Then
groups are further shortened and shortened to
the lowest possible group , i.e. , the species.
In this the lowest diversity is seen , where
alike organisms are only present.
36. The Discoverer of the order
It was the greatest contribution
in Biological section of taxonomy
given by the great scientist
CARLOUS LINNAEOUS. Not
only this , but he also gave the
system of naming every known
organism by a unique name. For
this ,he is also called as the
“Father of Taxonomy”.
37. Nomenclature
It is defined as the ‘Method of Naming
things’
The way Carlous Linnaeus named
organisms is known as ‘Binomial
Nomenclature’ as it included two names
for every unique organisms.
In the system , first the GENUS of the
organism is written , followed by its
SPECIES and thus, every one has its
own unique name.
38.
39. Extra Knowledge
Do you know that the only organisms, which is
not classified into any kingdom are VIRUSES.
It's because they act as dead until they enter
others and get the components necessary for
its revival.
If learning the hierarchal order is a little
difficult for you , then this statement can
help you out :
