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.

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.
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.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

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.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.

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.

QUESTION
13. GUIDE
QUESTION
1. In letter A, is the ball at rest?
YES
2. How can you make the ball move?
The ball has to be pushed or pulled.
3. In letter B, what happens to the ball when you push it with
enough force?
The ball moves in the same direction as the force
4. In letter C, while it is moving, how can you make the ball
stop?
Exert a force opposite the motion of the ball
5. In letter D, how can we make the ball change its direction?
The ball has to be pushed sideways.
14. What have you observe in the
following illustration? How
do the ball undergo motion?
15. What have you observe in the following
illustration?
The ball will not move when there is no force applied to it (Figure
6A). If you push the ball, it will move or roll across the surface of the
table (Figure 6B). And when it is again pushed in the direction of its
motion, it moves faster and even farther (Figure 6B). But when you
push it on the other side instead, opposite to the direction of its
motion, the ball may slow down and eventually stop (Figure 6C). Lastly,
when you push it in a direction different from its original direction of
motion, the ball also changes its direction (Figure 6D).
16. How do the ball undergo motion?
Force can make
the ball, or any
object move, move
faster, stop, or
change its
direction of
motion.
But, does this occur always? Can force always effect
change in the state of motion of an object?
19. What is;
A. magnitude – refers to the size or strength of the force. It is commonly
expressed in Newton (N) for Meter-Kilogram-Second (MKS) system, Dyne (dyn)
for Centimeter–Gram–Second (CGS) system and pounds (lbs) for Foot–Pound–
Second (FPS) system. In the International System of Units (SI), Newton is
commonly used which is named after Sir Isaac Newton, an English physicist and
mathematician.
B. direction – points to where the object goes. The direction of the arrowhead
indicates the direction of the force. The length of the arrow represents the
amount of force (relative magnitude).
C. point of application – the location of where the force is applied.
D. line of action – is the straight line passing through the point of application and
is parallel to the direction of force.
20. 2 TYPES OF
FORCE
Contact forces – forces where
objects touch or contact with
each other.
Non-contact forces – forces
where objects do not touch or
contact with each other. These
forces act over a zone or area
called field.
21. CONTACT
FORCE
Applied – a force given to a person or object by another
person or object. Its symbol is F depending on who or what
applies force to the object. If a boy applies a force to a wall, we
denote it with FBOY. Refer to the figure below.
22. CONTACT
FORCE
Friction – is the force acting against or opposite an object in contact
with which makes the movement of the object slow down. Its symbol
is written as Ff.
Air resistance denoted by FAIR is an example of frictional force
of the air against a flying kite, airplanes, parachutes or those in
skydiving sports. For free-falling objects, this force is always
considered negligible, meaning the magnitude is unnoticeable.
23. CONTACT
FORCE
Normal – is the force that acts
perpendicular to the surface of the object in
contact with. Its symbol is FN.
26. Gravitational Force
Gravitational force causes objects to fall down to the
ground.
What is the importance of gravitational force?
It makes satellites and smaller objects stay in orbit
near the more massive planets.
27. Gravitational Force
Mass and distance of the two objects affect the
gravitational force that holds them.
What are the factors that affect gravitational force of an object?
“The bigger the masses of the objects are, the bigger
is the gravitational force between them. The closer the
objects are, the greater is the gravitational force
between them.”
28. Gravitational Force
EARTH has bigger gravitational force over the moon.
Base on the illustration, which celestial bodies has bigger
gravitational force?
“The bigger the masses of the objects are, the bigger
is the gravitational force between them. The closer the
objects are, the greater is the gravitational force
between them.”
29. Gravitational Force
However, the weight of an object depends on the mass
of the celestial body where the object is attracted to.
Meaning, we seem to be lighter when we are on the
moon than on the Earth.
30. NON - CONTACT
FORCE
Magnetic– are forces exerted on a field of
attraction or repulsion as in the case of magnets
and other magnetic materials. Magnets and
magnetic materials have two poles – the north
and south poles.

42. Balance Force
Forces that are equal in magnitude but
opposite in direction are called balanced forces.
Balanced forces do not cause a change in motion.
When balanced forces act on an object at rest, the
object will not move.
43. Unbalance Force
Forces that cause a change in the
motion of an object are unbalanced forces.
Unbalanced forces are not equal and in
opposite direction.
45. Net and Resultant Force
When we combine or add forces to
determine the net or resultant force, we
will limit to those forces which act along
the same line of action. The algebraic
signs + and – are used to indicate the
direction of forces. Unlike signs are
used for forces acting in opposite
directions, see figure 22 below.
49. 1. What if boy A and boy B pull the heavy cabinet at the
same time in opposite direction with 10 N and 5 N of
force respectively.
a. What will be the net force on the cabinet?
b. Will the cabinet move?
c. To what direction will it move?
Try this !
51. 2. From problem 1 suppose another Boy C pulls the heavy
cabinet with 5 N of force in the same direction with Boy A.
a. What will be the net force on the cabinet?
b. Will the cabinet move?
c. In what direction will the cabinet move?
Try this !
54. Net and Resultant Force
“When an object is at rest, a zero net
force would make the object remains at
rest. Moreover, when the object is
moving, a zero net force would make
the object maintain its velocity at a
given time interval. “
ANSWER:
YES
The ball has to be pushed or pulled.
The ball moves in the same direction as the force
Exert a force opposite the motion of the ball
ANSWER:
YES
The ball has to be pushed or pulled.
The ball moves in the same direction as the force
The ball has to be pushed sideways.
Consider a ball on top of a table as shown in Figure 6. The ball will not move when there is no force applied to it (Figure 6A). If you push the ball, it will move or roll across the surface of the table (Figure 6B). And when it is again pushed in the direction of its motion, it moves faster and even farther (Figure 6B). But when you push it on the other side instead, opposite to the direction of its motion, the ball may slow down and eventually stop (Figure 6C). Lastly, when you push it in a direction different from its original direction of motion, the ball also changes its direction (Figure 6D). In conclusion, force can make the ball, or any object move, move faster, stop, or change its direction of motion. But, does this occur always? Can force always effect change in the state of motion of an object?

Figure 7 shows how force acts on a ball, but you need to be familiar with the following terms:
Friction always opposes the motion of an object.
NEGLIGIBLE –not important
UNNOTICEABLE –not easily observe

Each team is pulling with equal magnitude of force, FA and FB , on the rope but in opposite directions. Neither team can make the other team move.
Suppose that one of the teams in tug-of-war, as shown in figure 16, exerts greater magnitude of force, FB, on the ground than the other team, the forces applied on the ground would no longer be equal. One team would be able to pull the other team in the direction of the larger force.
