A "lunar eclipse" and a "solar eclipse" refer to events involving three celestial bodies: the Sun ("solar"), the moon ("lunar"), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun.

Earth-Sun Relationships - Solar Noon Angles Introduction- The purpose.pdfPeterM9sWhitej
Earth-Sun Relationships / Solar Noon Angles Introduction: The purpose of this lab is to explain
the geographic and seasonal variations in the receipt of insolation (incoming solar radiation) that
is caused by Earth-Sun geometry. This exercise will allow you to examine how both latitude and
season affect sun angle. Earth-Sun Relationships: The distance between Earth and the Sun
averages about 150 million kilometers (about 93 million miles). Because of that great distance,
and Earth's relatively small size, it is reasonable to assume that the Sun's rays to Earth in straight
paths. Earth's axis of rotation is tilted by an angle of 23. 5 from the perpendicular, to the plane of
the ecliptic - the imaginary flat plane on which Earth revolves around the Sun. The seasons occur
because this tilt is oriented in the same direction throughout the year, with the North Pole always
pointing toward the North Star (Polaris). Thus, the Northern Hemisphere is tilted toward the Sun
during its summer months, and tilted away from the Sun during its winter months. The image
below shows how the Sun's rays strike Earth on both Solstices. For Lab 2, we'll focus on the
Solstices. The June Solstice occurs roughly on June 20-21, and on that day, the direct rays of the
Sun at local Noon strike 23. 5 North Latitude (also known as the Tropic of Cancer). That is the
Northern Hemisphere's first day of Summer; the Southern Hemisphere's first day of winter.
Conversely, the December Solstice occurs roughly occurs on December 21-22, and on that day,
the direct rays of the Sun at local Noon strike 23. 5 South Latitude (also known as the Tropic of
Capricorn). That is the Northern Hemisphere's first day of winter, and the Southern Hemisphere's
first day of summer..

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.
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.
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.
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.

Slide 1: Title Slide
Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion
Invite Audience: Open the floor for any questions or further discussion on the topic.
7. Day and Night As the earth rotates
on its axis, half of the earth
faces the sun and half of the
earth faces away from the sun.
The half of the Earth that faces
the sun will experience day while
the half of the Earth that faces
away from the sun will
experience night.
9. High and Low Tide High and low tide
is a result of the gravitational
pull between the sun and the
moon. When the earth rotates,
the sun and the moon pulls it,
however, one of the force is
usually stronger than the
other. Hence, we will experience
high and low tide.
11. Wind speed and Direction
Wind on the earth comes from
north, south, east and west
direction. As the earth rotates
on its axis, different places will
get stronger surge of wind as a
result of the speed of the
rotation
12. Image of Wind speed and Direction
Wind speed and Direction are how fast
the air is moving and from which
direction.
13.
14. The Earth revolves around the
Sun.
The Earth takes 365 ¼ days
to complete the revolution = a
year.
15. Earth revolves
around the sun
in a slightly
eccentric
elliptical orbit
once a year.
The speed of
earth’s
revolution is
about 18 miles
per hour.
16.
17. Three factors cause the seasons:
The revolution of the Earth around
the Sun.
The tilt of the Earth’s axis of
rotation respects to the Plane of the
Ecliptic.
The tilt of the Earth’s axis remains
constant
18. Revolution causes:
- The four characteristic
positions of the Earth (summer and
winter solstices and spring and
autumn equinoxes ) .
- The seasons of the year
19. Solstices and equinoxes
Solstice: one of two days in the
year when the Sun is at its
highest or lowest point in the sky
at noon (12 pm)
Equinox: one of two days in the
year when day and night are the
same length of time.
20. Summer Solstice marks the beginning of
summer on June 21/22. June 21 is the
longest day. When it is summer in the
northern hemisphere it will be winter in
the southern hemisphere and the sun is
directly over the tropic of cancer.
21. Winter Solstice marks the beginning of winter
on December 21/22. December 21 is the
shortest day. When it is winter in the
northern hemisphere it will be summer in the
southern hemisphere and the sun is directly
over the tropic of Capricorn.
22. Spring Equinox marks the beginning of
spring on March 20/21. When it is
spring in the northern hemisphere it will
be autumn in the southern hemisphere
and the sun is directly over the equator.
23. Autumn Equinox marks the beginning of
autumn on September 22/23. When it
is autumn in the northern hemisphere it
will be spring in the southern hemisphere
and the sun is directly over equator.
24.
25. Varying Length of Day and Night
The effects of revolution causes varying
length of day and night.
In December the sun is directly over
the tropic of capricorn, therefore,
there will be shorter days and longer
night.
In June, the sun is directly over the
tropic of cancer, therefore, there will
be longer days and shorter nights.
26. During the seasons, temperature changes
depend on angle at which the Sun’s rays
hit the Earth.
