The document discusses hydrocarbons and their classification. It states that hydrocarbons contain only carbon and hydrogen and are obtained primarily from petroleum and coal. Hydrocarbons can be saturated or unsaturated depending on whether hydrogen atoms can be added to the molecule. Saturated hydrocarbons include alkanes, which can be open or closed chain, while unsaturated hydrocarbons include alkenes, alkynes and aromatic compounds. The document also discusses hydrocarbon functional groups where hydrogen is replaced by other elements, and the nomenclature rules for naming hydrocarbon molecules.

Organic chemistry involves the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen, halogens, phosphorus, silicon, and sulfur.
This branch of chemistry was originally limited to compounds produced by living organisms but has been broadened to include human-made substances such as plastics. The range of application of organic compounds is enormous and also includes, but is not limited to, pharmaceuticals, petrochemicals, food, explosives, paints, and cosmetics.
Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. Alkanes have the general formula CnH2n+2 and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes.

We actually started to make a difference in the way students think and approach problems. We started to develop ways to enhance students IQ. We started to leave an indelible mark on the students who have undergone APEX training. That is why APEX INSTITUTE is very well known of its quality of education
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.
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.
(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.
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.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

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.
3. Hydrocarbons are organic compounds that contain
only carbon and hydrogen. They are extremely
important to our society because so many products
are derived from them: fuels, fabrics, plastics,
antifreezes, anaesthetics, insecticides, to name a
few. The major source of aliphatic hydrocarbons is
petroleum, an extremely complex mixture of
compounds. Each of us, on the average, uses several
tons of petroleum each year (directly or indirectly),
mostly for fuel. Aromatic hydrocarbons are mainly
obtained from coal, although small amounts are also
obtained from petroleum.
Eg.C4h10
BY :Shubham
4. Hydrocarbons may be saturated or unsaturated. A
saturated hydrocarbon is one that is maxed out in terms of
the number of hydrogen that can be present given the
number of carbons in the compound; it is impossible to
add more hydrogen atoms to the compound so it is
saturated with hydrogen. Acyclic alkanes are saturated;
there is no way additional hydrogen can be added while
keeping the same number of carbons and maintaining
normal bonding between the atoms.Alkenes, alkynes,
aromatic compounds, and cyclic alkanes are unsaturated
because hydrogen can be added to them, in theory and
usually in practice, making them into acyclic alkanes.BY :Shubham
5. The hydrocarbon that contain only carbon-carbon single bond is called Saturated
Hydrocarbon. These include open chain hydrocarbon as well as closed
chain hydrocarbons. These compounds are called saturated because
they have maximum number of bonded hydrogen
If different carbon atoms are joined together to form an open
chain of carbon atoms with single bonds, they are called Alkanes.
For example: 2-Methylpropane (Isobutane)
If carbon atoms form a closed chain or ring, they are called Cycloalkanes.
For example: Cyclopentane
BY :Shubham
7. Alkyl Groups
The removal of one hydrogen from a
molecule of alkane gives the corresponding
alkyl group. For example, if one hydrogen is
removed from methane(CH4), we get an
alkyl group called methyl ( -CH3). Thus alkyl
groups are univalent groups with general
formula CnH2n+1 .
Eg.
BY :Shubham
8. Alkenes show following types of structural isomerisms:
The isomers differ with respect to the chain of carbon atoms.
as in alkanes, ethene (C2H4) and propene(C3H6) can have
only one structure but alkenes higher than propene have
different structures.
For eg: 4 3 2 1 But-1-ene
CH3−CH2−CH=CH2
The isomers differ in the position of the double bonds. For eg:
CH2−CH=CH2−CH3 (But-1-ene) CH3−CH=CH−CH3 (But-2-ene)
BY :Shubham
9. The hydrocarbons which contain at least one special type of
hexagonal ring of carbon atoms with three double bond in
the alternate positions are called aromatic hydrocarbon. The
ring is called aromatic ring.
For example: i) Toluene ii) o-Xylene
The aromatic compounds may also contain more than one
benzene rings. For example: i) Naphthalene
ii) Anthracene
BY :Shubham
10. These contain a closed chain or ring in their molecules. They
have the general formula CnH2n.
For example: i) Cyclopropane- or
ii)Cyclobutane- or
BY :Shubham
11. Functional groups
Carbon forms bonds not only with hydrogen but also
with other elements as well such as oxygen, sulphur and
halogens. In a hydrocarbon chain, one or more hydrogen
can be replaced by these elements in such a way that the
tetravalency remains satisfied. Thus, an atom or a group
of atoms which largely determines the chemical
properties of an organic compound is called a functional
group
These heteroatoms are also present in some groups
and these groups confer characteristic properties of the
compound regardless of the carbon chain.
BY :Shubham
12. • Halo-groups: This group includes chlorine,
bromine, fluorine and iodine.
• Alcohol: The hydroxyl group attached to a
carbon chain forms alcohol.
General formula: CnH2n+1OH
Suffix used: ol
BY :Shubham
13. • Aldehyde: Carbon compounds containing -CHO
groups.
General formula: RCHO
Suffix used: al
• Ketone: Carbon compounds containing –CO-
groups.
General formula: RCOR
Suffix used: one
• Carboxylic Acid: Carbon compounds containing -
COOH groups.
General formula: RCOOH
Suffix used: oic acid
BY :Shubham
14. Homologous series is a family of
structurally similar compounds
containing the same functional group
in which two successive members
differ by –CH2
All members of a homologous
series are called homologues.
The most important homologous
series are as follows:
Alkanes, alkenes, alkynes, alcohols,
aldehydes, ketones, carboxylic acid,
etc.
BY :Shubham
16. Nomenclature Of Alkanes
Nomenclature implies assigning proper name to the basis of certain
standard rules so that the study of these compounds may become
standard. The rules for naming them are as follows:
i)
First of all, select the longest continues chain of carbon atoms in a molecule.
1 2 3 4 5 6 7 8 9
For eg. CH3– CH– CH2– CH2– CH2–CH– CH2– CH2–CH3
CH3 CH2−CH3
In the example ,the longest chain has nine carbons and it is
considered as parent root chain and carbon atoms which are
not included in parent chain are called substituents.BY :Shubham
17. When two or more substituents are present, then end of the parent chain
which gives the lowest set of the locants is preferred for numbering. This
rule is called lowest set of locants.
This means that when two or more different sets of locants are
possible, that set of locants which when compared term with other sets,
each in order of increasing magnitude, has the lowest term at the first
point of difference.
If the same substituent or side chain occurs more than once, the prefix
di(for 2), tri(for 3), tetra(for 4), penta(for 5),hexa(for 6)…etc., are
attached to the names of the substituents. The positions of the
substituents are indicated separately and the numerals representing
their positions are separated by commas.
BY :Shubham
18. If two or more different substituents or side chains are present in the molecule, they are
named in the alphabetical order along with their appropriate positions. Prefix are
ignored while comparing the substituents.
For eg: 1 2 3 4 5
CH3–CH–CH2–CH–CH3
CH3 CH3
2,4-Dimethylpentane
For eg: CH3CH3
5 4 3 2 1
