The document discusses Maglev trains, which use magnetic levitation to float above the guideway and reach very high speeds without friction. It outlines the history and technology of Maglev trains, including the different propulsion systems used like EMS and EDS. Maglev trains are propelled by electromagnetic forces and guided along the track. They have significant advantages over conventional trains like higher speeds up to 500 km/h, virtually no noise and friction, and improved safety. However, their construction and maintenance costs are higher than traditional trains.

Maglev Trains- Train That Fly on the AirOnkar Pawar
Maglev is short for Magnetic Levitation in which trains float on a guide way using the principle of magnetic repulsion. Each magnet has two poles. Now if you play with two magnets, you'll realize that opposite poles attract, whereas similar poles repel. This repulsive property of magnets is used in Maglev trains. However, instead of using permanent magnets, the principle of electromagnetism is used to create strong and large temporary magnets. When an electric current is passed through a coil of wire, magnetic field is generated around the coil according to Faraday's laws.
Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speeds.Maglev trains move more smoothly and more quietly than
wheeled mass transit systems. They are relatively unaffected by
weather. The power needed for levitation is typically not a large percentage of its overall energy consumption;most goes to overcome air resistance (drag), as with other highspeed transport. Maglev trains hold the speed record for rail transportation

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.
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.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
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.
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.

3. INTRODUCTION:-
The Maglev Train is one of the fastest
transport media in the whole world
• The maximum speed reached for a
Maglev train has been 581 kmh in
Japan
• The Maglev Train uses magnets to
reach a really high velocity
• It doesn’t touch the floor because It
levitates due to the magnets
• Maglev is a short form of Magnetic
Levitation
4. HISTORY:
1971: West Germany
(90 kmph)
1972 : Japan (60
kmph)
1975 : West Germany
(401.3 kmph)
1979 : Japan (517
kmph)
•Figure -Trial run of the Transrapid
TR06, near
Lingen, Germany [9]
5. The Technology:
3 types of technologies are in use:
EMS (Electro Magnetic Suspension)
EDS (Electrodynamic Suspension)
Inductrack System (Permanent Magnet Passive
Suspension)
6. EMS:
+++
Low magnetic fields inside and
outside the vehicle
Commercially available
No secondary propulsion system
needed
---
The system needs to be
monitored by outside system to
maintain the distance between
the Track and the train
Vibraitions may occur due to
instability and outside
monitering
8. INDUCTRACK SYSTEM:
+++
No power requiered to activate
the magnets
Can levitate at low speed
(5km/h)
Lower Costs
---
Wheels needed at slow speed
Principle : Same system as the EDS, but the track is made of permanent
magnets. Magnetic field placed under the train
9. WORKING:-
A maglev train floats about 10mm above the
guideway on a magnetic field
• It is propelled by the guideway itself
• Once the train is pulled into the next section the
magnetism switches so that the train is pulled on
again
• The Electro-magnets run the length of the
guideway
12. PROPULSION SYSTEM:-
•The system consists of
aluminum three-phase cable
windings in the stator packs
that are on the guideway
• When a current is supplied
to the windings, it creates a
traveling alternating current
that propels the train
forward by pushing and
pulling
13. • When the alternating
current is reversed,
the train brakes
• Different speeds are
achieved by varying
the intensity of the
current
• Only the section of
track where the train is
traveling is electrified
14. POWER SUPPLY
• Batteries on the train power the system, and
therefore it still functions without propulsion
• The batteries can levitate the train for 30
minutes without any additional energy
• Linear generators in the magnets on board of
the train use the motion of the train to recharge
the batteries
• Levitation system uses less power than the
trains air conditioning
15. MagLev vs. Conventional Trains
MagLev Trains Conventional Trains
No Friction = Less
Maintenance
Routine Maintenance
Needed
No Engine = No fuel
required
Engine requires fossil
fuels
Speeds in excess of
300 mph
Speeds up to 110 mph
17. Future of conventional trains:-
Future of conventional train is Maglev Train
Hundreds of miles would be possible in few
hours
18. Advantages:-
• It is 250 times safer than conventional railroads
• 700 times safer than automobile travel
• Speeds up to 500 km/h
• A accident between two maglev trains is nearly
impossible
• Smooth motion & Less noisy
19. Contd…
• The trains are virtually
impossible to derail
because the train is
wrapped around the
track
• Collisions between
trains are unlikely
because computers are
controlling the trains
movements
20. CONTD…
•The train is earthquake proof because the
greater space (10 mm) between the track and
the train leaves more room for track deformation
• Linear generators will produce all the electricity
needed in the train’s interior
• Only the part of the track that is used will be
electrified so no energy is wasted
21. Disadvantages:-
The big problem about this is that the pieces
for the maglev are really expensive
The procedure to build it up is very expensive
as well
22. CONCLUSION:-
• Maglev trains use magnets to levitate and
propel the trains forward
• Since there is no friction these trains can
reach high speeds
• It is a safe and efficient way to travel
• Its construction cost is more but
maintainance cost is less
