This work is a study of scintillator-based radiation detectors, and
how they perform using both traditional and modern photodetectors.
More specifically, we examine how a radiation detector utilizing
silicon photomultiplier-based readout performs compared to a
traditional photomultiplier tube-based detector. Silicon
photomultipliers show great promise in contemporary particle
physics for their small size, robustness, and efficiency compared
to traditional photodetector systems. We investigated the
practicality and efficiency of using silicon photomultipliers in
radiation detectors.
Experimental and theoretical study of nucleus-nucleus collisions is
a diverse field, allowing to address a wide range of fundamental
physics. In each domain of beam energies, from the Coulomb barrier
to ultrarelativistic energies, characteristic reaction mechanisms
contribute and offer possibility to obtain information on the
properties of nuclear matter under specific conditions, what allows
to determine a global equation of the state and construct a phase
diagram of the strongly interacting nuclear matter. The properties
of nuclear matter play role in understanding various phenomena in
nuclear astrophysics and astro-particle physics, from the
primordial nucleosynthesis through production of heavy nuclei,
properties of neutron stars, supernova explosions, to the physics
of the early Universe. The nucleus-nucleus collisions can be also
used as a practical tool for production of very exotic neutron-rich
nuclei, thus allowing to enter this yet completely unknown domain
with the potential for future discoveries of new nuclear phenomena.
Isaiah 42:5 Th us saith God the Lord, he that created
the heavens, and stretched them out; he that spread
forth the earth, and that which cometh out of it; he
that giveth breath unto the people upon it, and spirit to
them that walk therein: 6 I the Lord have called thee in
righteousness, and will hold thine hand and will keep
thee, and give thee for a covenant of the people, for a
light of the Gentiles; 7 To open the blind eyes, to bring
out the prisoners from the prison, and them that sit in
darkness out of the prison house. 8 I am the Lord: that is
my name: and my glory will I not give to another, neither
my praise to graven images. 9 Behold, the former things
are come to pass, and new things do I declare: before
they spring forth I tell you of them. As the trials of this
generation intensify, the Lord God will begin to do new
things to get Himself glory. Those who trust Him with
their lives will be prepared.
One current-day man, with a spirit like Moses, is to
publish what new things, and who, is to spring forth.
Deuteronomy 18:18 I will raise them up a prophet from
among their brethren, like unto thee (Moses), and will
put my words in his mouth; and he shall speak unto them
all that I shall command him. 19 And it shall come to
pass, that whosoever will not hearken unto my words
which he shall speak in my name I will require it of him.
The Lord God's word to all of creation from this
contemporary Moses is come: The Book Of Stone. Those
whom the Lord will call, may draw a kingly sword from
this stone.
With this spiritual sward,
And faith in the Lord,
Saints will overcome,
To the glory of the Kingdom
This book's importunate message is for those in the land of the
living. The judgment for the land in the west is set.
Amidst mounting fear, The Book Of Stone is God's light, from a man
with a spirit like Moses. Spiritually, YHWH will
remove the iniquity of those who seek Him. Physically, the world
will witness Moses, Elijah, and the servant BRANCH,
delivering believers to safety.
The secondary message is that a Redeemer will come in a way in
which none have considered. God Himself inspired the
compilation of the selected scriptures herein to announce that one
like unto the Son of Man will glorify God the Father
once again. And we shall go rejoining...

In this report of the proceedings of the Fifth Symposium prominent
world physicists give an account of the status of the understanding
of nuclear structure in the mass region from A=20 to A=60. Ten
invited papers cover various aspects of nuclear structure from both
the theoretical and the experimental points of view. Additionally,
four short papers presenting formal comments are included, along
with the edited discussions following the readings of the papers.
Two topics are treated in particular: the long-awaited application
of polarized beams to the study of nuclear structure is reviewed,
with results from Stanford University; and a technique is
described, that makes it possible for the first time to observe
directly the decay of nuclear states.
Death of all life forms is a fact. Random evolution of humans from
lower life forms is not. Is there life after death? What kind?
Where? Is there a God? What can be known about life after death?
This book answers these questions with established facts rather
than imagination and delusion.
Published to widespread acclaim, in Marie Curie and Her Daughters,
science writer Shelley Emling shows that far from a shy introvert
toiling away in her laboratory, the famed scientist and two-time
Nobel prize winner was nothing short of an iconoclast. Emling draws
on personal letters released by Curie's only granddaughter to show
how Marie influenced her daughters yet let them blaze their own
paths: Irene followed her mother's footsteps into science and was
instrumental in the discovery of nuclear fission; Eve traveled the
world as a foreign correspondent and then moved on to humanitarian
missions. Emling also shows how Curie, following World War I,
turned to America for help. Few people know about Curie's close
friendship with American journalist Missy Meloney, who arranged
speaking tours across the country for Marie, Eve, and Irene. Months
on the road, charming audiences both large and small, endeared the
Curies to American women and established a lifelong relationship
with the United States that formed one of the strongest connections
of Marie's life. Factually rich, personal, and original, this is an
engrossing story about the most famous woman in science that rips
the cover off the myth and reveals the real person, friend, and
mother behind it.
The study of the nucleon-nucleon interaction has a long history,
going back to 1932 (just after the discovery of the neutron by
James Chadwick). The force is responsible for binding protons and
neutrons into atomic nuclei but, unlike the cases of Coulomb or
Newtonian gravitational laws, the form of the fundamental NN strong
interaction and its constants are a priori unknown. The subject is
nevertheless important because the energy associated with the
binding of protons and neutrons to form atomic nuclei is the energy
used in nuclear power. The authors of the present volume deliver
accounts of current research on various aspects of the forces
between two or more nucleons and how they relate to experiments in
nuclear physics. General overviews, illustrated by appropriate
examples, are given both the theoretical and experimental knowledge
of nuclear physics that are prerequisites for the understanding of
the strong interaction. Two- and three-nucleon forces are among the
topics that are addressed and discussed including, for example, how
nuclear forces emerge from low-energy QCD via chiral effective
field theory. A comprehensive overview is presented of realistic
free nucleon-nucleon interactions and also two-nucleon dynamics in
a nuclear medium.
In this book some applications of artificial neural network in
nuclear engineering are presented. In densitometry, number of
scattered and counted gamma photons highly depends on material
density. Using this relation, two different multi-layer perceptron
artificial neural networks are proposed to predict material
density. The results of proposed ANNs show that the presented model
could be employed in densitometry of materials. Furthermore, the
development of an ANN model for prediction of the highest value of
X-ray yield in PFs is showed. The comparison between predicted and
experimental results by ANN model illustrates that there is a good
adaptation between them. So, the MLP architecture can be applied as
a high efficient tool to predict the highest value of X-ray yield
in the PFs.
On July 4, 2012, the Higgs boson, dubbed as the "God particle,"
which the physicists had been searching for more than 40 years now,
was announced to have been discovered by the Large Hadron Collider
(LHC), the world' largest particle accelerator operated by the
European Organization for Nuclear Research (CERN). Since the
Standard Model did not include the explanation of how the particles
got their mass, the Higgs mechanism called the Higgs field with a
mediating particle of the Higgs boson was invented as the particle
that provides the answer to the source of mass of the other
particles. On March 14, 2012, physicists at CERN finally confirmed
it, paving the way for the possible Nobel Prize nominations for
those who conceptualized it and those who worked to discover it. So
far amidst the excitement, what the physicists thought that the
discovery would bring forth in the advancement in physics was
nowhere to be found. With the author's publication of this book,
the author is refuting the existence of the "God particle"-the
Higgs boson. But more than that, this book is not even primarily
written to refute the Higgs boson. Rather, this book presents new
theories that will bring forth new advancements in physics, such as
the true understanding of charge (Charge theory), New Model of an
Atom (replaces the current model of an atom), source of mass of the
particles (Mass theory), theory on the structure of the atom of the
elements, Atom Law that will replace the Pauli Exclusion Principle,
theory on the structure of quarks inside the proton and neutron
(Quark theory), and the Theory of Everything that will revise the
Standard Model and provide the understanding of the fundamental
forces. (This book, together with the written but unpublished book
on theory on light and the future to be written book on the theory
on gravity will complete the Theory of Everything.) This book also
challenges another contender for the Theory of Everything, the
String Theory by showing (through Occam's razor) that we don't need
a whimsical theory to explain our practical observable universe. To
show the extent of change that this book brings, this book
challenges the works by physicists that were even award the Nobel
Prize. This book challenges the Bohr's and Schrodinger's Model of
an Atom, nuclear shell model of an atom, Pauli Exclusion Principle
(including the Aufbau Principle and the Hund's rule). Furthermore,
as a Theory of Everything, this book also challenges quantum
chromodynamics (QCD) and the Electroweak theory. For the physicists
who are looking for the New Physics, this is the Real New Physics
that will cause nothing short of a paradigm shift.
