Magnetic effects can be produced by electric currents. When a current flows through a conductor, it creates a magnetic field around the conductor. Three key relationships govern magnetic fields: (1) like magnetic poles repel and opposite poles attract, (2) the strength of a magnetic field depends on the amount of current and number of turns in a coil, and (3) changing magnetic fields can induce electric currents in nearby conductors based on Lenz's law. Electromagnets and transformers take advantage of these relationships to manipulate magnetic fields for applications like motors, generators, and power transmission.

INTRODUCTION
The phenomenon where by electricity creates magnetism is known as electromagnetism. When an insulated wire is wrapped with round an iron nail and the ends of the wire connected to the battery the nail becomes capable of picking up iron fillings paper. This is a simple electromagnet. The nail has been magnetized by the current in the wire. Disconnecting the wire from the battery the paper clips fall off. The nail looses most of first magnetism when the current is switched off. The passage of electric current along a wire creates a magnetic field around the wire. The lines of forces due to a straight current carrying wire are circles, center on the wire on the wire. The field is strongest near the wire the direction of the magnetic field is r

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.
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.
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.
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.
2. WHAT IS MAGNETIC EFFECT ?
A magnet is a substance which has a tendency of attracting some metals
when placed near it. When a linear piece of magnet suspended freely then it
always align in north – south direction. The end of bar magnet pointing
towards north is called North Pole; while the other end of magnet pointing
towards the south ,is called South Pole.
3. PROPERTIES OF MAGNET:
The ends of a magnet where the magnetic effect is maximum is called three
poles of a magnet. A magnet has two poles- North Pole and South Pole.
When a magnet is suspended freely it always comes to rest in North – South
direction.
The magnetic poles exert forces on each other .Like poles repel and unlike
poles attract each other .
Magnetic poles always exists in pairs.
Repulsion is sure test of magnetism.
4. MAGNETIC COMPASS:
Magnetic compass is simple device to find the direction .It is a small magnet
which is pivoted at its centre so that it can rotate freely in its horizontal
plane. It always points towards North – South Direction.
5. MAGNETIC FIELDS:
The region around a magnet in which the force of the magnet can be
experienced is called its magnetic fields.
Magnetic fields is of two types:
a) UNIFORM MAGNETIC FIELD: If the magnitude and direction of magnetic field is
same at every point then field is said to be uniform magnetic field.
6. NON UNIFORM MAGNETIC FIELD: If the magnitude and/or direction of
magnetic field is not same every point then field is said to be non uniform
magnetic field.
7. MAGNETIC FIELD INTENSITY:
Magnetic field intensity at a point is defined as the force experienced by an
isolated unit North Pole placed at that point. S.I unit of magnetic field
intensity is tesla (T).
8. MAGNETIC LINES OF FORCE OR FIELD
LINES :
These are imaginary lines along which the magnetic field acts. Magnetic lines
of force is curve or line along which an isolated north pole compass would
move, if free to do so, in the given magnitude field. Tangent to it at any
point gives the direction of intensity or force at that point.
9. PROPERTIES OF MAGNETIC LINES OF
FORCE:
Magnetic lines of force moves from North poles to South poles outside the
magnets and from South pole to North pole inside the magnet. So magnetic
lines of force are closed continuous curves.
Tangent to magnetic lines of force at any point gives the direction of
magnetic field at that point.
No two magnetic lines of force can intersect each other ,because is two
magnetic lines of forces can intersect each other at any point, then at that
point, we have to draw tow tangents, which is not possible.
In a region ,where magnetic field is stronger , magnetic lines of forces are
crowded; while thinning of lines of force means region is weaker field.
Magnetic lines of force contract longitudinally and dilate laterally.
10. MAGNETIC FIELD DUE TO BAR MAGNET
Magnetic fields due to bar magnet can be finding either using iron fillings or
by using a compass needle.
11. MAGNETIC EFFECT OF ELECTRIC
CURRENT:
When electric current is passed through a conductor ,magnetism is produced
around it and the conductor acts like a magnetic effect of current.
SNOW RULE: If current flows from South to North ,when conducting wire is
held over the magnetic needle, then the North Pole of needle deflects
towards the West. If the direction of the current is reversed ,then the
direction of deflection is also reversed.
12. AMPERE’S SWIMMING RULE: Imagine a man is swimming along the wire in the
direction of flow of the current with his face always turned towards the
magnetic needle, and then the north of the magnetic needle will get
deflected towards his left hand.
13. MAGNETIC FIELD DUE TO A STRAIGHT
CURRENT CARRYING CONDUCTOR :
The shape of magnetic fields due to a straight current carrying conductor is
concentric whose axis is the current carrying conductor.
14. RIGHT HAND THUMB RULE:
Grasp the wire in the right hand so that the thumb points along the wire in
the direction of the current ,then the direction in which fingers encircle the
wire gives the direction of the magnetic field.
15. MAGNETIC FIELD DUE TO A CURRENT
CARRYING CIRCULAR LOOP:
The strength of magnetic field produced by a circular coil containing current
can be increased by-
a) Increasing the number of turns of wire in the coil.
b) Increasing the current flowing through the coil and -.
c) Decreasing the radius of the coil.
16. CLOCK RULE:-
The polarity of any face of coil can be known by clock rule. According to clock
rule if the current round any face of the coil flows in anticlockwise direction
it behaves like a north pole and if the current flows in the clockwise
direction, the face acts as a south pole.
17. MAGNETIC FIELD DUE TO A SOLENOID:
A Solenoid can be defined as a long coil of many circular turns of insulated
metal wire wrapped closely in the shape of cylinder such that its length is
very large as compared to its diameter.
When current is passed through such a Solenoid ,a magnetic field is produced
around and within it. The end of the solenoid at which current flows in the
anticlockwise direction behaves as a magnetic north pole and other end of
the solenoid at which current flows in clockwise direction behaves as the
magnetic south .
The magnetic field pattern due to solenoid is very much similar to that of a
bar magnet.
The magnetic field inside the solenoid is uniform and outside its is non-
uniform .The direction inside the solenoid is from south to north pole and out
side it is from north to south pole.
18. On reversing the direction of current flowing in the solenoid the north pole
and the south pole get interchanged.
Strength of magnetic field produced by a current carrying solenoid depends
upon:
a) Number of turns: Larger the number ,stronger is the magnetic field produced.
b) Strength of current: Larger is the amount of current ,stronger is the magnitude
field.
c) Nature of core: Strength of magnetic field also depends on nature of core material.
19. ELECTROMAGNETS:
Electromagnet is essentially a soft iron core, embraced by a current carrying
insulated coil. It produced strong magnetic field when a current flows through
it.
20. DIFFERENCE B/W AN ELECTROMAGNET
AND PERMANENT MAGNET:
ELECTROMAGNET
Its is temporary as it exhibits
magnetic force only, when current
flows through it.
It can produce very strong
magnetic force.
Its strength can be changed.
Its polarity can be changed.
PERMANENT MAGNET
It is a permanent magnet.
It produces comparatively much
weaker magnetic force.
Its strength cannot be changed.
Its polarity cannot be changed.
21. FORCE ON A CURRENT CARRYING
CONDUCTOR IN A MAGNETIC FIELD:
When a current carrying conductor is placed in a magnetic field, it
experiences a force on it.
The strength of force depends on:-
The strength of the electric current flowing through the conductor.
The length of the conductor .
The strength of magnetic field.
The sine of the angle between current and magnetic field.
22. The force is max- when the angle
between current and magnetic
field is 90* and it is mini- when
angle is 0*.
The direction of the force can be
find by Fleming’s Left Hand Rule.
According to it: Stretch the thumb,
the forefinger and the middle
finger of your let hand such that
they are mutually perpendicular to
each other .If forefinger points in
the direction of the magnetic field
and the middle finger in the
direction of the current , then the
thumb will point in the direction of
force
23. ELECTROMAGNETIC INDUCTION (EMI):
The phenomenon of the production of induced current in a circuit, due to change
in magnetic field linked with it (called flux), is called electromagnetic induced
current depends on the rate by which the magnetic field linked with the coil is
changing .Current can be induced in a coil when:-
o There is a relative motion between a coil and a magnet.
o A magnetic field linked through a coil is changed by rotating the coil.
o When a current or magnetic field changes in a coil which is laced in the near of the given
coil (in which current is to be induced).
The direction of induced current can be obtained by Fleming’s right hand
rule.
If we stretch the right hand such that forefinger, central finger and thumb are
mutually perpendicular to each other. If the forefinger indicates the direction of
the magnetic fields and thumb shows the direction of motion of the conductor,
then central finger gives the direction of induced current.
24. DIRECT AND ALTERNATING CURRENTS:
DIRECT CURRENT:- DC always flows in the same direction.
ALTERNATING CURRENT:- AC is one in which the direction of current changes
periodically and value changes continuously. In India frequency of AC is 50 Hz
and Rms voltage is 220 volt. It means the current changes its direction after
every 1/100s.
ADVANTAGES OF AC OVER DC:
a) AC can be transmitted over a long distances.
b) AC can be converted into DC.
c) AC is easier and cheaper to generate.
d) The magnitude of AC can be easily increased or decreased by using transforms.
e) The cost of transmission of AC power is low.
DISADVANTAGES OF AC OVER DC:
a) AC is much dangerous to work as compare to DC as it gives severe shock.
b) AC cannot be use in electroplasting.
25. DOMESTIC ELECTRIC SUPPLY:
The electricity supplied to our homes is AC of 220 V having frequency 50 Hz.
In homes there are two types of circuits: Lighting circuits with 5 A fuse (for
electric bulbs, fans, tube lights etc.) and power circuits with 15 A fuse (for
room heaters, refrigerators ,air conditioners etc.)
While connecting the two distribution circuits with the main supply ,each
circuit is connected in parallel.
26. A COMMON DOMESTIC ELECTRIC CIRCUIT
CONSISTS OF:
MAIN BOARD:- It is provided outside the house .It contains the main fuse and
the meter. The ends of the cables from the street electric pole are connected
to the two terminals of electricity board fuse. This fuse is further connected
to an electricity meter for measuring the consumption of electricity energy.
The electric cable coming to the house consists os three separate insulated
wires; live wire or phase wire( red in colour) ,Neutral wire (black in colour)
and the earth wire(green in colour). The potential difference between live
and neutral wire is 220 V.
DISTRIBUTION BOX:- It contains main switch and fuses for each circuit. In
main switch live wire and neutral wire from electric meter are further
connected .By switching off the main fuse, the electricity supply to the house
can be cut off completely when required. After that elericity is distributed to
different part of the house through various distribution circuit is provided wit
a separate fuse in live wire.
27. ROOM WIRING:- All electrical appliance are connected across the neutral and
live wires in parallel so that :-
i. Same potential difference acts across all of them .
ii. Any electrical appliance may be switched on or off with out any interference to
the other .
iii. It is one of the appliance gets fused ,it will not affect the working of other
appliance.
iv. Each appliance has a separate ON/OFF switch to control the flow of current
through it. The switch is always connected in live wire.
v. Most of the domestic appliance are connected to the main by means of sockets ( a
three pin plug ). The three brass cylindrical pins are fitted on a socket. The lower
terminals which are smaller in length and diameter are fore live wire (right one )
and neutral wire (left one) .The upper terminal which is longer and thicker
diameter is connected to the earth wire.
28. ELECTRICAL PROBLEMS:
OVERLOADING:- All electrical appliances and wires used in the circuit have a
definite power rating .If the appliances connected through the wire draws
more current than its safety limit, the wire gets heated. This fault is called
overloading. Due to this ,wire gets heated to a very high temperature anf=d
sometimes melts or burns.
29. SHORT CIRCUITING:
Sometimes due to defective wiring or improper insulation of wires, the live
wire comes in the direct contact with the neutral wire. Due to this the
resistance of the circuit becomes very small and a large amount of current
flows through the circuit causing overheating .This is called short circuit.
Overheating due to short circuit damages the appliances or may cause
electric fires.
ORECAUTIONS TO AVOID THE OVERHEATING AND SHORT CIRCUITING OF
DOMESTIC ELECTRIC CIRCUITS:-
1. All wires used in electrical circuit should have good quality insulation and proper
amperage.
2. All joints of naked wires should be covered with insulating tape.
3. Immediate replacement or repair of the damaged or defective wire, switches,
plugs and sockets etc. should be done.
4. Fuse of proper rating and material should be used.
5. All connections at switches ,sockets, plugs must be tight to avoid sparking.
30. SAFETY MEASURES:
EARTHWIRE:- It is used as a safety measure especially for those appliances
that have a metallic body and are frequently touched by us with bare hands.
The earth wire comes from the earthling pit prepared near the house. It is
connected to the main switch from where it goes along the live and neutral
wires from the main board. Now when an electric appliance is connected to
the electricity supply line through the three pin plug, the green coloured
earth wire keeps the appliance set zero potential. Also the thick wire used as
earth wire can carry a large current in case of short circuiting or over heating
and ensure that any leakage of current to the metallic body of the appliance,
floes directly to the earth and the used does not get and electric shock.
31. FUSE:-
It is the most common safety device .A fuse in the circuit prevents damage to
the appliance and the circuit in the case of overload and short circuit which
may be caused due to faulty wiring or use of poor quality wires or voltage
fluctuations . A fuse is based on the joules law of heating. It has a wire of low
malting point which melts in passing high current and brakes the electric
circuit , thereby stopping the flow of current and protect the appliance from
getting damaged.
