فقد ثبت في الحديث الصحيح أن النبي صلى الله عليه وسلم قال: افترقت اليهود على إحدى وسبعين فرقة، وافترقت النصارى على اثنتين وسبعين فرقة، وستفترق هذه الأمة على ثلاث وسبعين فرقة كلها في النار إلا واحدة، قيل: من هي يا رسول الله؟ قال: من كان على مثل ما أنا عليه وأصحابي. وفي بعض الروايات: هي الجماعة. رواه أبو داود والترمذي وابن ماجه والحاكم، وقال: صحيح على شرط مسلم . It is proven in the authentic Hadith that the Prophet peace be upon him said: Jews divided to seventy one bands, and the Christians split
1. Evaluate how Bragg’s X-ray crystallography experiment advanced our understanding of materials. Discuss how their discoveries enabled scientific discoveries that followed. Bragg’s experiment was conducted to observe how the crystal lattice structure of a crystal affects the diffraction of a beam and allows us to calculate the angle of diffraction. The experiment involved an X-ray tube shining a beam onto a crystal, allowing the beam to be diffracted, this beam is split into multiple X-ray
In other words, Compton scattering occurs when only part of the photon energy is transferred to a free electron and the photon scatters with lower energy than the incident one. This increases the wavelength of the photon and increase the kinetic energy of the electron. The increase
color in the sky at sunset (and sunrise) is due to an effect called Rayleigh scattering”. Rayleigh scattering can explain why the sky is blue. During the day, the sun on the top of the head, as the sun passes through the atmosphere, and the air molecules (whose radius is far smaller than the wavelength of visible light) Rayleigh scattering occurs, because the blue light wavelength longer than red light. As Rayleigh scattering occurs more intense, the scattered blue lights was full of the sky, and make
"I will plough the land, turning up the black soil" (L.1-2). By using "I will," he sounded excited and motivated. This makes it so the reader becomes happy and is motivated to do something. Another is "I sing as I go scattering emeralds" (L. 17–18). By singing and scattering seeds, he makes it sound as if he is dancing while singing a tune. This would make readers cheerful and feel upbeat. Through the use of tone, the author has a good mood while reading the
Earth Burial: Not all cemetery spaces are reserved for traditional casket burials. Many, including Oak Grove Cemetery, have space for cremated remains. You can also make arrangements to place an urn in a family lot which otherwise contains caskets. Scattering the Ashes: Many families scatter their loved one’s remains in a place with special significance to the deceased. It isn’t a decision to be made lightly,
paranormal due to their lack of light and overall creepiness. However, one of the most haunted locations may be the hardest to identify and most unimaginable, Disneyland. Disneyland proves to be haunted by its ghost sighting, deaths, and human ash scatterings.
scattered window are not the same as window itself. So, what if the atoms of the baseball caused the scattering of the atoms of the window and the baseball itself caused the shattering of the window. This would result in distinct effects and causes, and neither will overdetermine the other (p. 63). Merricks replies to this by saying that in his argument, the "shattering of the window” is the same as “scatterings”, but this objection is considering it as two distinct events (p. 63). However, if we suppose
diagnostic imaging. In anode a major part of energy is converted to heat, the anode should have a high melting point and good heat conductivity to get a high amount of x-ray energy. A photon undergoes two process incoherent scattering and coherent scattering. coherent scattering is when photon changes its direction of motion, and when the photon energy increases the probability for photon decreases and it increases with the increase atomic number. X-rays has clinical advantages for instance in
A sequence of SPM maps derived from VIIRS imagery using QAA-V revealed interesting patterns of SPM concentrations in Galveston Bay following Hurricane Harvey (Fig. 8 & 9). Hurricane Harvey, a category-4 hurricane, caused catastrophic flooding in the Houston metropolitan area and surrounding regions of Galveston’s Bay drainage basin with great potential to degrade the bay’s water quality. The dramatic increase in the discharge of water from the Trinity and San Jacinto Rivers into Galveston Bay (Fig

The advantages administered in logistics can consolidate physical things, for instance, sustenance, materials, animals, equipment and liquids, and moreover special things, for instance, supervise time, information, transport unit Pricing and Quantity , particles, and essentialness
On page 26 of The Lost City Of Z: A Tale Of Deadly Obsession In The Amazon, David Grann Presents information on how the “Roar” of the engine sent animals “Scattering” into the Treetops. The animals that David Grann is referring too are known as “Howler Monkeys”. Howler Monkeys are native to the South and Central American Forest. I’m going to explain to You more about what a Howler Monkey is, like how big the Howler Monkey
the angle through which these -particles were scattered by a thin piece of metal foil. Because it is unusually ductile, gold can be made into a foil that is only 0.00004 cm thick. When this foil was bombarded with -particles, Geiger found that the scattering was small, on the order of one degree. These results were consistent with Rutherford's expectations. He knew that the -particle had a considerable mass and moved quite rapidly. He therefore anticipated that virtually all of the -particles would
Physics of ultrasound Dr. Madhav Swaminathan, Dr. Aashish Jain Abstract: Medical practice of ultrasound is constantly expanding. It is now used for not only screening and diagnosis of various diseases, but also to enhance care in the field of anaesthesia and intensive care. Ultimately, the quality of care depends on imaging quality. Practitioners of ultrasound therefore need to understand the physics and principles behind the technology in order to create optimal images. In this article, we will
the cash of exploration scattering and there is a general assention that grant ought not be the safeguard of a couple. Researchers and clinicians over the world are ravenous for administrations that can keep them side by side of the most recent advances in science and prescription. Another key component of 21st century correspondence is quickness—officially apparent in current styles of news scope and online networking use. Open access distributed encourages fast scattering of investigative learning
The recent spurt in terrorist activities involving TNT as an explosive and its widely reported role as an environmental contaminant made it an analyte of prime concern for the scientific community dealing with environmental problems and national security [1-3]. Consequently, there is an imperative need for rapid and steadfast methods of trace detection of TNT, for screenings in airports, analysis of forensic samples, and environmental analysis [4-5]. Traditionally, x-ray based instruments and trained

A key point of Zen Buddhism and Taoism is that everything is transient and always changing, whether it be life or nature. Kenko compares the impermanence of the woman’s affection to the fading, scattering cherry blossoms. Furthermore, Kenko experiences a great sadness when he realizes that she and all humans are always steadily dying, and will soon leave this world. The transience of life is a theme found in both Zen Buddhism and Taoism. Both ideologies
Introduction: High Performance Liquid Chromatography or also known as High Performance Liquid Chromatography is one of the most powerful and most commonly used analytical separation technique. HPLC is a form of liquid chromatography that separated solutes/compounds dissolved in the solution (High-performance liquid chromatography, 2012). It is an improved form of column chromatography, where the solvent is passed through under high pressure instead of letting it drip down due to gravity. The sample
the objects under analysis. When a monochromatic light impacts on a material, the light is scattered. Most of the scattered light has the same wavelength as the inci- dent light (the Rayleigh scattering) and a small portion is shifted in wavelength due to molecular vibrations and rotations (the Raman scattering) [8]. With this spectro- scopic technique, it is possible to analyze particles in the micron order and to identify species at molecular level with minimum or no preparation at all. In micro-Raman
