	Alteration
		Alteration phenomena occur in various rock types, but are perhaps most effectively studied when found in igneous masses.
		As a result of the alteration studies it seems clear that the clay minerals of the sill are hydrothermal in origin even under near surface conditions.
		In general, the intensity of alteration may be shown to be greatest in the vicinity of known ore bodies.

	Expanding Your Mind: Alter Your Basic Psionic Combat
		Alterations cannot be applied to the imbed psionic attack ability of the soulknife.
		An attack mode with this alteration causes the defender to become blind and deaf for a number of rounds equal to the points of ability damage that would normally be dealt.
		An attack mode with this alteration causes the defender to become fatigued for a number of rounds equal to the points of ability damage that would normally be dealt.

	Hydrothermal Veins and Alteration
		Hydrothermal alteration is a change in the mineralogy as a result of interaction of the rock with hot water fluids, called “hydrothermal fluids”.
		One example of alteration zoning associated with a volcanic vent is shown in Figure 8 – 1 B. This example indicates an inner zone of silicification forms within a central breccia formation, and an outer zone of propylitic alteration lies adjacent.
		The intensity of alteration refers to how well-developed the alteration is. It could be incipient mineral growth due to weak development, or it may be pervasive throughout the rock, indicating strong development.

	All about skarns (Site not responding. Last check: 2007-10-21)
		The influx of meteoric water and the consequent destruction of skarn minerals during retrograde alteration is one of the distinctive features of skarn formation in a shallow environment.
		Alteration of igneous rocks is common with widespread albite, orthoclase, and scapolite veins and replacements, in addition to endoskarn.
		Another evidence of distal hydrothermal alteration related to skarn deposits is the occurrence of hairline fractures and stylolites in sedimentary rocks beyond the limit of calc-silicate minerals.

	PSRD Hot Idea: Regarding liquid water on Mars
		One is an experimental study of the alteration of a rock similar to Martian meteorites, conducted by Leslie Baker, Deborah Agenbroad, and Scott Wood (University of Idaho).
		The alteration products had to have something to alter, so they must have formed during the past 1.3 billion years, long after the suspected wet and warm climate on Mars had changed to the dry, cold conditions found today.
		The alteration products must have formed after that time, showing that water was present on the surface in small quantities during the past billion years.

	ALTERATION
		In slightly altered pieces, alteration is generally confined to narrow halos along fractures, veins, and exterior surfaces; many pieces have fresh interiors.
		Alteration is mostly restricted to oxidation halos, paralleling fractures, veins, and outer margins of pieces (Figs.
		Some pieces have concentrically zoned alteration halos that change from dark orange-brown to brown in the outermost zone to a lighter brown zone and, finally, to a darker gray inner zone adjacent to the lighter gray fresh interior (e.g., Section 187-1163A-3R-1 [Piece 1] and 9R-1 [Piece 9]).

	National Cancer Institute - Genetic Testing for BRCA1 and BRCA2
		Inherited alterations in the genes called BRCA1 and BRCA2 (short for breast cancer 1 and breast cancer 2) are involved in many cases of hereditary breast and ovarian cancer.
		Women with an inherited alteration in one of these genes have an increased risk of developing these cancers at a young age (before menopause), and often have multiple close family members with the disease.
		Alterations in the BRCA2 gene have also been associated with an increased risk of lymphoma, melanoma, and cancers of the pancreas, gallbladder, bile duct, and stomach in some men and women.

	ATTACHMENT 1: LANDFORM ALTERATION POLICY CONCERNS
		In addition to the concern for alteration of natural land forms, the Commission, through other Sections of the Coastal Act, is mandated to minimize streambed alteration, and to protect water quality, environmentally sensitive habitat areas, and other resources.
		In addition to the direct concern for this alteration, there are concerns about the resultant effects from such alteration, including but not limited to, erosion and siltation, habitat loss, water quality degradation and long term alteration of drainage patterns and surface water flows.
		Land form alteration is a significant environmental concern and this concern is recognized in the California Coastal Act.

	Hydrothermal Alteration (Site not responding. Last check: 2007-10-21)
		The spatial scale of hydrothermal circulation and alteration in crustal rocks is important because of its implications for the volume of rock that can be leached of metals to form concentrated ores.
		Hydrothermal alteration of oceanic crust is important to understanding the formation of seafloor massive sulfide deposits, the geochemical cycle of sulfur in the oceans, and ultimately the origin of magmatic sulfur erupted from volcanic arcs over subduction zones.
		Sulfur mass balance and isotopic systematics accompanying hydrothermal alteration of oceanic crust by seawater were developed by Alt [1994], based on studies of ophiolite complexes.

	Q & A for Estimating Cancer Risk in Ashkenazi Jews
		This study was designed both to test for the frequency of the alterations and to find out if volunteers from the general population with an alteration were at greater risk for cancer than those without an alteration.
		In particular, three alterations were initially identified in Ashkenazi families with hereditary breast cancer and later were found in an unusually high percentage of the general Jewish population.
		Although certain alterations that may be unique to Norwegian, Icelandic, and Dutch families have been identified, the frequency in the general population is not known, and no such studies have been planned to date.

	What's A Major Alteration?
		The FAA is very clear that the alteration must be accomplished in accordance with technical data approved by the FAA administrator, in other words a 337 form must be used and at times a DER data will be required.
		Alterations of the following parts and alterations of the following types, when not listed in the aircraft specifications issued by the FAA, are airframe major alterations (in other words items not covered on the aircraft type certificate).
		Installing an alternator circuit breaker in an aircraft that did not have one available from the factory is grounds for a major alteration according to the rules and FAA approved data would have to be used via the 337 form.

	Gale Encyclopedia of Cancer: Taste alteration
		Taste alteration refers to a decrease in the ability to taste foods (hypogeusia), changes in how food tastes (dysgeusia), or the complete loss of the ability to taste foods (ageusia).
		Taste alteration occurs when the taste buds are damaged by cancer therapy or as a symptom of xerostomia or infection.
		The resulting alterations in taste are varied but the most common complaints include: a metallic taste, enhanced taste of bitter flavors (such as beef, pork, coffee, chocolate), and reduced taste of sweet flavors.

	ATTACHMENT 2: LAND FORM ALTERATION: CCMP COASTAL HAZARDS REGULATORY PROCESS
		The alteration of natural land forms and the impacts from such alteration were raised as concerns during the development of the California Coastal Plan and subsequently in the preparation and implementation of the Coastal Act.
		Slope alteration should not be allowed to meet septic design requirements, and special septic design may be required in areas of high slope constraint.
		No construction, land form alteration or vegetation removal is allowed in riparian protection areas and the only alteration of stream channels shall be for water supply or flood impoundment, where no other protection is possible.

	ALTERATION
		Alteration occurred under oxidizing conditions and with high water-rock ratios, resulting in the development of light to dark yellow-brown colors in the most exposed rocks (e.g., near the outer zones of cooling units) (Fig.
		As with the upper alteration zone in basement at Site 1185, we again noticed a clear relationship between vein abundance and the color of host-rock alteration.
		Because the degree of alteration is a function of permeability, the abundance of veins, pervasiveness of the alteration, and development of light and dark yellow-brown alteration colors indicate that basement in Hole 1187 was initially the most permeable of any drilled during Leg 192.

	Psychomorphics
		Additive alterations include causing the target to sense something which isn't really there, or altering the way in which he senses an object or person ("psychic illusion").
		Note that the type of alteration (adding a memory, removing or changing one, etc.) is not important in determining the difficulty of the trial.
		The relative complexity of the alteration is the primary determinant.

	The Seam Method of Pattern Alteration
		When I was studying pattern alteration in college, I learned that no matter what method you use to alter a pattern, when you're done, all that's really changed is the outline, or outer edge of the pattern.
		As we've continued to work with the seam method, it has become clear that in addition to the other benefits, the method allows alterations to be confined precisely to areas where they're needed and to stay clear of those areas where no change is wanted.
		Think through each alteration individually, then as it relates to adjoining pattern pieces and to other alterations, which you may be able to make at the same time.

	Alteration Permits -- 44520000
		On major alterations (the elevator is to remain out of service during the alteration), the owner/installer contacts the inspector upon completion of the alteration to schedule a date and time to meet on-site with the inspector to inspect and/or witness tests of the alteration.
		On minor alterations (where the elevator has been allowed to transport the public), the owner/installer contacts the inspector upon completion of the alteration to determine if the owner/installer is needed onsite for the alteration inspection.
		If the alteration does not pass (items failed or work not completed within the scope of the alteration), the unit will be removed from service and the owner/installer informed that the unit has failed the inspection.

	III. LCP REVIEW RELATING TO LAND FORM ALTERATION
		The absolute minimum for alteration of natural land form would be zero, or no alteration at all.
		Limitations for land form alteration should specify both the allowable range for grading and for overall disturbance, either as an absolute quantity or as a percentage of the site.
		In areas where land form alteration may be of significant concern, it would be appropriate to provide in the LCP a review of the staffing and support which will be provided for such enforcement.

	Retrograde Alteration (Site not responding. Last check: 2007-10-21)
		The term retrograde alteration refers to an alteration stage in which higher temperature, generally anhydrous, minerals are replaced by lower temperature, generally hydrous, minerals.
		In other cases, retrograde alteration is concurrent with strong metasomatism, such as during mineralization with various sulfide minerals.
		In general, retrograde alteration is more intense and more pervasive in shallower skarn systems.

		Overexpression of S100A7 in a breast cancer cell line is associated with increased malignancy and with several changes in gene expression that are compatible with an alteration in Jab1 activity [7].
		The mechanism that underlies this downregulation and possible alteration of expression is unknown, but it is unlikely to be attributable to genomic changes and may reflect changes in cellular differentiation or response to extracellular stress signals [2].
		However, in the present study we observed that the overall incidence, as opposed to the level of S100A7 expression, does not necessarily differ significantly between pure DCIS and DCIS that is associated with invasive carcinoma.
