Yosemite National Park is known for its breathtaking scenery including waterfalls, giant sequoia trees, and iconic rock formations. It was established in 1890 and protects diverse plant and animal species. The park is home to over 400 species including American black bears, Sierra Nevada bighorn sheep, and bats. Rock types within the park include quartz diorite, volcanic rocks from the Cenozoic era, conglomerate sedimentary rocks, and Half Dome displays the geological principle of crosscutting relationships as intrusions cut through older rock layers.

Introduction
After visiting the Los Angeles Natural History Museum, I learned so many things concerning the animals that were there in the early days and how they looked like, as well as, how they lived . The Museum has a large paleontological collection that helped me develop a better understanding of the Earth’s biota. The Museum’s collection ranges from fossils to the modern organisms which are collected from the entire world, and it is therefore a good place to begin with when exploring on the paleontological exhibits and other historical items. During the visit at the Museum I learned of a few things that I never knew existed and other facts too that are new. In this article there are a lot of areas and information that are presented showing all the paleontological exhibits and other historical items.
Exhibit 1. The Gray Fox
The gray fox (Botanical name Urocyon cinereoargenteus) is one of the interesting exhibits I found at the museum. The exhibit on Fray Fox features 4 photographs indicating how the small American mammal survives in the wild. The photograph below (Image 1) shows a Gray Fox family in their burrow. It reflects the legacy of life by clear illustrations of how the Gray Fox adapts to the environment. From what I gathered, the animals are largely monogamous. The photograph shows an ideal family in their broken terrain habitat. Gray foxes opt to live in broken terrain and rocky areas in order to ease the process of making new homes.
An adult male is seen overlooking his family that is resting outside their den, probably to show gender roles in the social life of the gray fox. The female (much smaller than the male) lies next to their kit. The fresh soil dug in their burrow shows that their home may be new, indicating that the species may have moved in more than once. Gray foxes diet is comprised of vegetation, small mammals such as mice, and insects. The photograph captures an environment (San Gabriel Mountains, California) capable of meeting the species food needs. Green vegetation provides gray foxes with vegetation foods. Insects feeding on the vegetation are most likely part of the gray fox’s diets. Gray foxes are spread across central USA, Southern Eastern Canada, and Western Venezuela (Reid, 2016).
Information obtained from (Reid, 2016) indicates that one of the most peculiar traits of the gray fox is their ability to climb trees in order to evade predators. The strong claws used to dig and remove earth are used to climb trees. This makes them the only species of the dog family with the ability to climb trees.

A Visit to La Brea Tar Museum
1.0 Introduction
The visit to the La Brea Tar Museum would be one of the most influential experiences in my career and life as whole. The visit is one of the events that enhance my passion to advance my career in a history-related discipline. I believe that only the visit could equip me the immense knowledge that I now possess concerning some of the most admired historical facts and concepts. Through the museum tour, I have gathered substantial knowledge regarding the Pleistocene extinction. I now appreciate that most of the largest mammals that the present generation might admire to see perished during the Pleistocene era. Moreover, I have learned the lions, cats and other members of saber-toothed cat family have shared ancestry. I appreciate that the huge and powerful canines possessed by the saber-toothed cat family was a crucial component of their survival ways. The visit to the museum has familiarised me with several facts about the extinct camels. I admit the fact that camels are presently associated African and Asian deserts though; they originated from North America. On the other hand, the tour to La Brea Tar Museum has cleared my doubts regarding dinosaurs. Presently, I have indisputable knowledge about dinosaurs and the early carnivores. I have clear understanding on how dinosaurs emerged, survived as well as their extinction. Concerning the early carnivores, I admit that adaption to their feeding methods like the huge and powerful canines have not changed significantly throughout the evolution.
2.0 Pleistocene extinction
In essence, the visit to the La Brea Tar Museum enhanced my knowledge concerning the Pleistocene extinction. I learned from the visit that the change of climate among other factors led to the death of the last mammoths. It is clear to me that the mammoths disappeared approximately 3,700 years ago according to the human recorded history. Some historians associate the extinction with the comet impact and human actions. I am aware that the human beings contributed to the extinction of mammoths and Saber-toothed cats among other animals after visiting the La Brea Tar Museum. The impact of Pleistocene extinction was so extensive that it led to the loss of giant ground sloths, terror birds and the spotted hyenas in Europe. I have learned from the visit that the Pleistocene extinction was a world disaster and it did not take place at once (Haynes, 2009). Notably, the geological pattern of the extinction indicates that the extinction assumed the path of wandering human beings. During the tour, I read well that climate change and human beings are the key culprits of the Pleistocene extinction though, some historical scientists claim that a falling comet triggered the extinction. The mammoths disappeared shortly after human beings settled in th ...
CONTINENTAL DRIFT THEORY AND DISCONTINUOUS DISTRIBUTION.pptxrimshaijaz6
theory of continental drift
The theory of continental drift was proposed by German scientist Alfred Wegener in the early 20th century. The theory suggests that the continents were once part of a supercontinent called Pangea, which broke apart and drifted to their current locations. The Earth's crust is split up into seven large plates and a few smaller ones, all of which can slowly move around on the Earth’s surface.
discontinuous distribution a distribution in which populations of related organisms are found in widely separated parts of the world, e.g. lung flukes in Australia, Africa and South America. Such a distribution is thought to indicate the great age of the group, with intermediate populations having become extinct.

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.
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.
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.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

2. INTRODUCTION: WHAT IS
YOSEMITE?/ HISTORY
Yosemite is a National Park within the Sierra Nevada mountain
range, it is known for it’s breathtaking scenery, ancient
Sequoia trees, astounding waterfalls, and iconic vista points:
Bridalveil falls, El Capitan, and Half Dome.
Before being coalited into a park, Native Americans had
settled into Yosemite valley throughout the early 1800’s until
the gold rush of 1864 brought an abundant amount of miners
into the area. In 1864, conservationists convinced President
Abraham Lincoln to declare the area in a public trust fund of
California, this was the first time the U.S government had
preserved land for the enjoyment of others.
No one took charge until a environmentalist by the name of
John Muir had noticed that the land had been overrun by sheep
grazing due to a lack of govt help, so him and Robert
Underwood Johnson, a fellow collogue, lobbied for something
to be done, so on October 1st, 1890, Congress sanctioned off
1,500 sq. miles of land which became Yosemite and was the
third National Park to ever be created in the U.S.

Roosevelt on a

(1903)
3. ALL DIFFERENT KINDS OF
CREATURES
Yosemite is home to a copious amount of animals including 90
mammal, 262 bird, 22 reptile, 11 amphibian, and many other
species which total in over 400 altogether, that make the area so
diverse, along with being one of the reasons why it’s ecosystem
thrives so well!
It is said that predators are extremely attracted to the park and
depending on the area between the forest and meadow, one is
able to find a large array of organisms scouring around, smaller
animals like it as well for it’s free roaming ranges and overall
protection for the outside world, many are known to be at higher
elevations.
The park contains 40 species that hold a special title under the
California endangered species legislation, recently it was
revealed that the Grizzly Bear, California red-legged frog, and
foothill yellow-legged frog had been added as well.
Some of the most populated and well known animals within the
land are the American Black Bear, the Sierra Nevada Big Horn
Sheep, and the Big Brown Bat.
4. THE AMERICAN BLACK BEAR
It is believed that bears’, including the American Black Bear, ancestry reaches all
the way back to 30 million years or so to, “…a family of small mammals known as
the Miacids (Miacidae). Some of the canine species resembled bears, and we refer
to them as bear dogs or Amphicyonidae. The size and appearance of the bear dog
varied from small and dog-like to big and bear-like…The family of real bears can
ultimately be traced back to the oldest genus, the Ursavus, which was roughly the
size of a sheepdog and had evolved from a canine ancestor” (Bears p.2).
The bear specie can be broken down into three subspecies, “…the giant panda
(Ailuropodinae), the spectacled bear (Tremarctinae), and the real bears (Ursinae).
The family of Ursinae consists of six different species, all of which have similar
external characteristics like strong claws and a robust body” (Bears p.3).
Many scientists believe that multiple bear species, like the polar and brown bear,
had hybridized while evolving, causing multiple similar characteristics among
several bear families, some of these traits include increased strength, a larger
size, along with more advanced hunting skills such as climbing and such.
Fossils of this creature have been indeed found by paleontologists, but have a
hard time determining exactly what era they come from, some say they date back
to the Paleocene and Eocene epochs, but this is mostly for Miacid fossils.
7. THE WESTERN FENCE LIZARD
(SCELOPORUS OCCIDENTALIS)
Another specie that is constantly seen throughout the National Park is the Western Fence
Lizard (aka the blue bellied lizard) and evolutionary wise is believed to have been around for
millions of years, at one time (during the Carboniferous Period) reptiles had dominated the
planet, but due to a mass extinction in the Jurassic Era, it had dwindled down to only 6,000
reptilian species that survived.
This creature is believed to be part of the Phrynosomatidae family and, “Evidence suggests
the family originated in one unknown area and spread with continental drift. Several genus
and species evolved from this family due to the isolation of phenotypes and challenges of
climate and predation. These genus are further differentiated by morphological
characteristics” (Bailey p.9).
One of these characteristics that is well-known and have scientists wondering is how they
evolved the trait of thermoregulatory behavior, a study had been done which observed the
relationship between this occurrence, temperature of their environment, and their body
temperature once they are born. It had been found that, “…significant variation in body
temperature was associated with family membership, suggesting that thermal physiology
has a genetic basis. Moreover, growth rate was correlated with body temperature among
families in each population suggesting a genetic correlation underlies the phenotypic
correlations. Thus, genetically based variation in thermal physiology contributes to
differences in growth rate among individuals within a population as well as to differences
9. SCELOPORUS OCCIDENTALIS
FOSSIL
Now
Fossils of this creature have been found
in Western Oregon and other portions of
North America, some dating back to
their prehistoric roots, the picture below
is an archaic example.
10. THE CALIFORNIA POPPY
(ESCHSCHOLZIA CALIFORNICA)
Along with many types of creatures that roam the park, there is
beautiful vegetation that surrounds the area, along with a large array
of wildflowers, like the California Poppy that grazes the hill sides.
Their ancestor is also not well known, but are seen by professionals
as extremely archaic and many feel that they belong to the subclass
Magnoliiade, it is said that plants within this group are, “…extremely
heterobathmiid, that is, they have a very disharmonious combination
of both primitive and derived characters… the magnoliid families
evolved in various directions, but they most likely all evolved from a
common ancestor but the relationships between the families is not
yet understood… the magnoliids today may only be remnants of a
large ancient group of flowering plants and because of this the
subclass Magnoliidae is a collection of ‘living fossils’… they close to
Ranunculales and Berberidales (especially to Hydrasidaeae and
Podophyllaceae) and Glaucidiales and share a common origin with
them (Burt p.3)
The California Poppy is classified as a Angiosperm which first
appeared in the Lower Cretaceous Period(125 million years ago), but
became more diverse in the Middle Cretaceous Period (100 million
years ago), they are known to branch off into other areas within the
family such as Euangiosperms and Eudicots, it then reaches
Ranunculales and finally into Papaveraceae, also known as the poppy
family. They are also known for pollenating quite well, as an

13. QUARTZ DIORITE
Along with the vast organisms within Yosemite, it’s geology
is just as interesting, Quartz Diorite, a prime example, is
classified as a igneous plutonic rock, but not technically
granitic, and are known to be composed of five minerals:
quartz, potassium feldspar, plagioclase feldspar, biotite, and
hornblende. They contain for the most part large portions of
quartz and feldspar, plutonic rocks had began to form during
the Cretaceous Period.
Characteristics: Grey to dark grey color, richer in sodium
and poorer in calcium, their surface is speckled, also have a
coarse grained texture, they have repeated intrusions along
with deep erosion due to once being formed deep beneath
the earth and being exposed to the surface.
How to identify it: When looking at the different rock
samples, I was able to identify a quartz diorite in the park
mainly to it’s texture, color, and the amount of trauma it had
been through (erosions).
Plutonic rock: a
body of intrusive
igneous rock that
is crystallized
from magma
slowly cooling
below the surface
of the Earth.

14. VOLCANIC ROCKS (CENOZOIC)
Along with the various types of rock formations within
Yosemite, there is an abundance of volcanic rocks that
populate the area, they can be classified as plutonic as
well, but depends on their contents. Most volcanic rocks
are composed of a array of minerals especially basalt, but
depends for it can either have basalt which means it has a
low level of silica and is similar to gabbro or a rhyolite
which has a high level of silica and is more similar to
granite. Examples of this found in the park are basalt
flows, latite tuff, and latite lava flows
Characteristics: A limited range of composition, contain
little to no quartz, tend to be more fine grained or glassy
with a small amount of visible minerals.
How to identify it: I was able to find this specific rock
because of it’s smoother textures, more shiny/ clearer
appearance, and it’s darker color, also the area I was in
was well known for having these kind of rock formations.
It is also known that most of the volcanic rocks within
the park are from the late Cenozoic era and were formed
by large amounts of lava from smaller eruptions and
known to be found in eastern Yosemite at the Mono
15. CONGLOMERATE (SEDIMENTARY)
A rock formation that I have seen multiple times all
over Yosemite and within the Sierra Nevada
Mountain range, but never knew the name of was
the conglomerate and is scattered all throughout
the area. They are composed of rounded clasts filled
in between with smaller particles or a molecular
glue that holds it all together and can contain many
different sediments such as quarts, limestone,
chert, along with many other kinds.
Characteristics: Have a more rough and course
grained surface, depending on the clasts, they can
have the same strength are concrete and be smooth
to touch, the clasts are very visible, most of these
variables depend on the size and materials it’s made
of.
How to identify it: Although the conglomerate rock
can take on many forms, I was able to identify it
within the park due to all the visible clasts I could
see like a kaleidoscope of different sediments. Also
because of it’s tendency to not break cleanly, was
another contributing factor that made it stand out
as well.
16. PRINCIPLE OF CROSSCUTTING
RELATIONSHIPS (HALF DOME)
The principle of crosscutting relationships states, “…that an igneous
intrusion or a fault must be younger than the rocks that it intrudes or
displaces” (Monroe, 419), the infamous half dome is this principle in
action.
The reason behind why is applies to this principle has to do with the
process in which it was created, when it was formed, intrusions of
magma molten rock had solidified underground and this happened
repeatedly, as other rock layers eroded away, it had revealed what we
see today.
17. ANGULAR UNCONFORMITY (THREE
BROTHERS ROCK)
An angular unconformity is
defined as, “…an erosional surface
on tilted or folded strata over
which younger strata were
deposited” (Monroe), it is safe to
say that Three Brothers Rock can
be considered this kind of
unconformity because how each of
the “brothers” are folded over the
next and so on, also given by it’s
texture, one can see that a great
deal of erosion had occurred here.
