The Book Of Stone - For A Light To The Gentiles (Paperback): By Moses The Book Of Stone - For A Light To The Gentiles (Paperback)
By Moses
R636 Discovery Miles 6 360 Ships in 10 - 15 working days

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...

R1,868 Discovery Miles 18 680 Ships in 10 - 15 working days

This book deals with some of the recent as well as traditional problems in nuclear structure physics originating from various nuclear models. It introduces the recent developments in nuclear theories such as effective relativistic mean field theory and non-relativistic Skyrme-Hartree-Fock approach. The main features of these theories used in this present work are in microscopic level, that deals with a wide range of nuclear systems ranging from light to heavy and superheavy nuclei including proton to neutron drip-lines. Special emphasis is given to the fundamental nucleon-nucleon interactions in relativistic mean field theory, in terms of the meson masses and their coupling constants. Investigations are also done for finding the Island of stability and the alpha decay half-life for superheavy valley. Moreover, the various decay modes including the rare event as cluster decay are taken into account for discussions.

Radioactive Clouds of Death Over Utah - Downwinders' Fallout Cancer Epidemic Updated (Paperback): Dr. Daniel W. Miles Radioactive Clouds of Death Over Utah - Downwinders' Fallout Cancer Epidemic Updated (Paperback)
Dr. Daniel W. Miles
R412 Discovery Miles 4 120 Ships in 10 - 15 working days

RADIOACTIVE CLOUDS OF DEATH OVER UTAH

From 1950 to the 1958 moratorium on atmospheric testing, the Atomic Energy Commission detonated over 100 atomic bombs at the Nevada Test Site. The inhabitants of St. George, Utah--the so-called downwinders--were repeatedly in the fly zone of these toxic, windblown clouds--so much so that St. George became known nationwide as Fallout City, USA.

In the fall of 1979, Stewart Udall, along with a team of lawyers, came to St. George to announce plans for a class-action lawsuit against the United States because the local people were struggling with tragedies inflicted by a cancer epidemic foisted on them by the Atomic Energy Commission. After interviewing 125 people during a four-day period, the Washington lawyer said that cancer rates in the area were three or four times greater than normal.

Many people in southwestern Utah believe that thousands of citizens throughout the West are still dying from radiation-exposure inflicted on them by fallout from the Nevada Test Site during the 1950s.

The author has spent decades investigating the Test Site issues. He was living in St. George, Utah during the atmospheric testing period in the 1950s. He knows the people. He has read every local paper from the period, counted the tombstones, tracked the anecdotes to ground and studied the dozens of scientific studies on the impact of fallout on the health of the local people. This book is the result of that investigation.

The author, Dr. Daniel W. Miles, Professor Emeritus, Dixie State College, received his Ph.D. from the University of Utah in 1967. He taught upper division physics including radiation physics at Westminster College from 1968 to 1985 and continued his teaching career at Dixie State College. He is the author or coauthor of fortytwo publications in peer reviewed scientific journals.

George H. Miley, S. Krupakar Murali
R5,840 Discovery Miles 58 400 Ships in 10 - 15 working days

This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment proposed for demonstrating breakeven conditions for using p-B11 in a hydrogen plasma simulation. This book also: Offers an in-depth look, from introductory basics to experimental simulation, of Inertial Electrostatic Confinement, an emerging method for generating fusion power Discusses how the Inertial Electrostatic Confinement method can be applied to other applications besides fusion through theoretical experiments in the text Details the study of the physics of Inertial Electrostatic Confinement in small-volume plasmas and suggests that their rapid reproduction could lead to the creation of a large-scale power-producing device Perfect for researchers and students working with nuclear fusion, Inertial Electrostatic Confinement (IEC) Fusion: Fundamentals and Applications also offers the current experimental status of IEC research, details supporting theories in the field and introduces other potential applications that stem from IEC.

R2,011 Discovery Miles 20 110 Ships in 10 - 15 working days

The book sheds light on the role of isospin degree of freedom in reaction dynamics of heavy-ion collisions via transverse in-plane flow. Role of the nuclear symmetry energy and nucleon-nucleon scattering cross section has been envisaged in detail. The investigations presented in the book revealed that the transverse flow can act as a very promising probe of the nuclear symmetry energy at supra-saturation density region, where the nuclear symmetry energy is highly uncertain. The details of nuclear dynamics involving neutron-rich colliding nuclei has also been presented. In short, this book encompasses gross features about the collision dynamics of transverse flow and its disappearance as well as related phenomena of isospin asymmetric nuclei.

Secret of Electricity (Paperback): Amin Elsersawi Secret of Electricity (Paperback)
Amin Elsersawi
R528 Discovery Miles 5 280 Ships in 10 - 15 working days

Dr. Elsersawi, a pioneer in the filed of electricity and its effect in living things, challenges the traditional mechanistic in our thinking about the living inner process of magnetism. He found clues to the interaction between electromagnetic field and the human body. Like the gravity of the earth and the quantum in the universe, the magnet has different effect on different regions of the earth and the universe. The strength and location of natural magnetic fields on the earth can influence our minds, alter our character, and noticeably affect our health. The text explains the effect of magnetic fields on humans at different altitudes on the earth. For example, the intensity of magnetic fields at the two poles is greater than at the equator.

This reference explores the sources, characteristics, health hazards and benefits of electromagnetic fields (EM), of low-frequency fields and of radio frequency radiations. Pulsed Electro Magnetic Field Therapy (PEMF) is also expressed in pain relief, osteoporosis treatment, fibromyalgia treatment, fracture healing, rheumatic pain, and stress reduction. More over, electricity and electromagnetic fields do affect the spiritual quality of the human. Electricity can vibrate cells, nerves, bones, organs, and change the chemical reaction and metabolism. Disharmonious or unbalanced vibrations show themselves in many ways including discomfort, disease, illness, fatigue, and a variety of different symptoms. Higher vibrations mean healthy body, and low vibrations mean an ailing body.

Interestingly, particular electromagnetic waves can cause degenerative disorder of the central nervous system (the brain), which leads to Parkinson's and Huntington's diseases, and impairments both in sequence learning, and in the initiation and termination of voluntary movements.

The book contains materials describing different waves of EM of alpha, beta and Gamma to explain their interaction with biological systems.

This book is the second volume exploring the properties of faster than light particles (tachyons). The existence of tachyons has not been proved yet. But the instantaneous nature of Quantum Mechanics and the behavior of particles in Black Holes prove faster than light motion occurs in nature. In volume 1 the author showed that one can derive the form of The Standard Model of elementary particles if neutrinos and down-type quarks are tachyons. In this volume the author shows that these tachyons cause Parity, CP and CPT violation. Also the General Theory of Relativity is extended to Complex General Relativity and its vierbein version. The theory's complex coordinates are mapped to real-valued coordinates (that we observe) using a transformation composed of SU(3) and two SU(2)xU(1) groups - the very groups that appear in The Standard Model. Volume 1 showed that these same groups play a similar role in The Standard Model by mapping complex, faster than light coordinates to real-valued coordinates. Thus the same groups are the basis of Complex General Relativity and The Standard Model. WIMPs (Weakly Interacting Massive Particles - Dark Matter?) appear naturally in this Standard Model. WIMP atoms and chemistry is described. Lastly, the kinetic theory and thermodynamics of systems of tachyons is developed. An appendix is attached with a description of Complex General Relativity that appears in the author's earlier "Quantum Big Bang" book.

Gas-filled detectors have always been widely used because of their simplicity, being proportional counters the most indicated for making spectroscopic studies as well as for counting. This book is focused on a particular proportional counter: a windowless gas flow, which presents the particularity that the source is directly introduced in the counting chamber. The procedure of its full setting-up, including the choice of geometry, the wires, the required nuclear electronics and the optimal parameters of working, as well as the results analyzed for several alpha decay emitters and a few beta samples, are described. The understanding of the working of the detector and the learning of its optimal use are reached in an exprimental way through addressing all the difficulties found in its tune-up, beginning from the construction of the device.

This book is a M.Sc. thesis in theoretical nuclear physics. It is supervised by the professors of theoretical nuclear physics at faculty of Science, Cairo university: M. Y. M. Hassan, M. Y. H. Farag, and E. H. Esmael. The elastic scattering and breakup of neutron halo nuclei are studied in this work. The halo nuclei exhibit a strong cluster structure and anomalously large matter radii. Their separation energies of the halo neutrons are very low, so they can easily broken. These nuclei are so short lived that these cannot be used as targets. Instead, direct reactions can be done in inverse kinematics. The optical potential is constructed only from the framework of the folding model. It has few fitting parameters and give good agreement with the cross section data. Thus, it is not necessary to introduce a large number of arbitrary fitting parameters as done in the phenomenological potentials. Different densities for the halo nuclei are used and tested. The parameters of the density-dependent term are adjusted to fulfill saturation of nuclear matter. The breakup effect is studied by adding a dynamical polarization potential with different forms to the "bare" optical potential.

Nuclear Power Reactors (Paperback): Ghosh Pradeep Nuclear Power Reactors (Paperback)

R957 Discovery Miles 9 570 Ships in 10 - 15 working days

Nuclear Reactors are now part of our daily need. This book intends to showcase how effectively the power can be calculated in hot channels and provide easy access to important information of reactor functionality. Many safety and design calculation codes are available. These can predict the important core parameters such as reactor power; thermal and fast flux distribution (depending on the type PWR, BWR, RBMK, BREEDER etc.) at an assembly level with high accuracy. Most safety studies concerning reactor cores take into account the local acceptance criteria like the maximal local power density for example. To satisfy these criteria and to avoid huge safety margins, it is necessary to know the detailed power distribution in the whole core the most accurately as possible. Solving the transport equation over a whole core is almost impossible because it is consuming too much of CPU time. Some methods were developed to reconstruct the power distribution from results of nodal diffusion codes. During the past years, the system code ATHLET has been successfully coupled with the coarse mesh diffusion code QUABOX-CUBBOX, both developed at GRS mbH Munich. For more visit http: //www.grs.de

The level of radiation due to the naturally occurring radioactive materials was investigated and the radiological hazard was calculated for Mount Homa located at longitude 330 26' E and 340 34' E latitude 00 30' S and 00 20' S in southwestern Kenya. The absorbed dose rate in air above the ground was measured with hand held survey meters. The measured mean dose rate of 474 nSv/h translated to annual dose due to external radioactivity of 4.15 mSv/y. The radioactivity concentrations of K, Ra and Th in rock and soil samples were measured using gamma ray spectroscopy. The cumulative mean activity concentrations obtained were 915, 195 and 409 Bq/kg of K, Ra and Th, respectively. The calculated mean absorbed dose rate was 383 nGy/h. The resultant total effective dose equivalent was 5.03 mSv/y. The RESRAD code enabled modeling of K, Th and U environmental pathways. This led to exposure pathways of external radiation, inhalation and ingestion resulting in total effective dose equivalent to exposed individuals estimated as 4.93 mSv/y. The Mt Homa study has established radiation dose to the population and qualifies the region as a high background radiation area due to carbonatite rocks.

R1,620 Discovery Miles 16 200 Ships in 10 - 15 working days

This book describes how the effects of nature's own nuclear reactors have shaped the Earth, the Solar System, the Universe, and the history of life as we know it. It focuses on observed effects that are poorly explained by our standard theories, identifies certain errors in those theories, and shows how these effects are caused by natural nuclear fission reactors. The theory of Plate Tectonics is wrong, and it is shown that expansion of the Earth causes continental drift. A physically reasonable mechanism is proposed for expansion and observational data are presented to show that this occurs. Evolution is explained as punctuated equilibrium, with mutations caused by abrupt surges of radiation, and related life forms that have been interpreted as seperate species are actually the result of radiation injury. This view is particularly effective as applied to humans. The ability of the dinosaurs to live so large is explained by use of Earth Expansion and a more massive atmosphere to provide buoyancy and effective transpiration of oxygen. These effects also explain how pterodactyls and ancient birds could fly. Expansion induced by impacts at the end of the Cretaceous caused the atmosphere to thin and the dinosaurs collapsed. Analysis of geological and biological data supports this. The astronomical distance scale is shown to be wrong, based on the misconception that trigonometric parallax is an absolute measurement. It isn't, and the method is led astray by the overwhelming number of asteroidal fragments masquerading as stars. The measurements of an expanding Universe are shown to be in error, and an expanding Universe is not needed by an alternative interpretation of Einstein's equations. This interpretation is based on the equal creation of matter and antimatter, which is known to occur. Spiral galaxies are not vast Island Universes of stars as we have thought, but are shown to be the strewn fields of debris from the nuclear fission detonation of distant planets.The Universe is not made up of 96% Dark Matter and Dark Energy, but is instead very ordinary. Abundant evidence and references provide support for all these interpretations. This book opens new opportunities for research by correcting several fundamental errors in our concepts of the Earth, Life, and the Universe.
