Late Heavy Bombardment The Late Heavy Bombardment (abbreviated LHB and also known as the lunar cataclysm) is a hypothetical event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago, corresponding to the Neohadean and Eoarchean eras on Earth.

phagocytosis phagocytosis. PHAGOCYTOSIS. A three-stage process by which phagocytes (neutrophils, monocytes, and macrophages) engulf and destroy microorganisms, other foreign antigens, and cell debris. three-stage process by which phagocytes (neutrophils, monocytes, and macrophages) engulf and destroy microorganisms, other foreign antigens, and cell debris.

Difference Between Primary and Secondary Immune Response | Immune Response The exponential phase is the period during which there is a rapid increase in antibody levels due to secretion of antibodies by many plasma cells. c. After the exponential phase the antibody level remains relatively at a constant level because the secretion and degradation of antibodies occur almost at equal rates.

Kinetic bombardment Kinetic bombardment has the advantage of being able to deliver projectiles from a very high angle at a very high speed, making them extremely difficult to defend against.

NPI Frequently Asked Questions HIPAA requires the adoption of a standard unique identifier for health care providers. NPIs allow for simpler electronic transmission of HIPAA standard transactions. The NPI is the only health care provider identifier that can be used for identification purposes in standard transactions by covered entities.

Phase (waves) Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called phase offset or phase difference. Another usage is the fraction of the wave cycle that has elapsed relative to the origin.

Difference Between Primary and Secondary Immune Response | Immune Response The primary immune responses can be divisible into four phases (lag phase, exponential phase, steady state phase, and declining phase) (Fig. 7.1). a. The lag (latent) phase is the period from the initial exposure of immunogen to the time of detection of antibodies (In humans the average time of lag phase is about one week).

Solid-phase synthesis In chemistry, solid-phase synthesis is a method in which molecules are bound on a bead and synthesized step-by-step in a reactant solution; compared with normal synthesis in a liquid state, it is easier to remove excess reactant or byproduct from the product.

Barrage (artillery) A German artillery barrage falling on Allied trenches at Ypres, probably during the Second Battle of Ypres in 1915, during the First World War. A barrage is a particular method of delivering massed artillery fire from a few or many batteries. Individual guns or howitzers are aimed at points, typically 20–30 yards (18–27 m) apart, along one or more lines that can be from a few hundred to several thousand yards long.

Blast crisis The three phases of the condition are the chronic phase, aggressive phase and finally the blast crisis. A blast crisis is occurs when over 30% of the cells in the blood or bone marrow are immature blood cells (blast cells).

Phase-shift keying There are three major classes of digital modulation techniques used for transmission of digitally represented data: 1  Amplitude-shift keying (ASK) 2  Frequency-shift keying (FSK) 3  Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a reference signal (the carrier wave). The modulation occurs by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and Bluetooth communication.

phase Definition of phase for Students. 1  1 : a step or part in a series of events or actions : stage I have completed the first phase of my training. 2  2 : the way that the moon or a planet looks to the eye at any time in its series of changes with respect to how it shines The new moon and the full moon are two phases of the moon.

Definition of Mobile phase Definition of Mobile phase. The solvent that moves the solute through the column. In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions.

- by Nancy Atkinson on December 10, 2009. Artist impression of the Late Heavy Bombardment period. Credit: NASA. A new study finds the gases which formed the Earth’s atmosphere – as well as its oceans – did not come from inside the Earth but from comets and meteorites hitting Earth during the Late Heavy Bombardment period. A research team tested volcanic gases to uncover the new evidence.

phase Phases of the moon. The definition of a phase is a distinct period of time in something's development. An example of a phase is the final part of a multiple part landscaping project. An example of a phase is when you can the various shapes of the moon.

Lag Phase Is a Distinct Growth Phase That Prepares Bacteria for Exponential Growth and Involves Transient Metal Accumulation During batch culture, a typical bacterial growth curve shows five distinct phases of growth: lag phase, the delay before the start of exponential growth; exponential phase, where cell division proceeds at a constant rate; stationary phase, when conditions become unfavorable for growth and bacteria stop replicating (8, 70, 78); death phase, when cells lose viability; and, finally, long-term stationary phase, which can extend for years .

S phase S phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. Precise and accurate DNA replication is necessary to prevent genetic abnormalities which often lead to cell death or disease. Due to the importance, the regulatory pathways that govern this event in eukaryotes are highly conserved.

- A “phase-of-the-moon bug” is a bug that is dependent on some external factor, often a factor that is actually undetermined. The phase-of-the-moon bug is also sometimes called a “Heisenbug” for Heisenberg's uncertainty principle, when the bug is inconsistent or unable to be replicated on return attempts.
