khalifa Etiology of cancer Many factors may play a role in etiology of cancer   I Geographical amp environmental factors These factors form about 65 of all cancer etiology while genetic factor form about 26 42 of cancer etiology. SURFACE TEXTURE:. “ The characteristics quality of an actual surface due to small departures from its general geometrical form which, occurring at regular or irregular intervals, tend to form a pattern or texture on the surface”. Angle:. In Geometry an . angle. is the figure formed by two rays sharing a common end point, called the vertex of the angle.. . The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other. Definition of Material Handling. :. “ Material Handling embraces all of the basic operations involve in movement of bulk, packaged, & individual products in semisolid or solid state by means of machinery, & within the limits of place of business”. Gauges perform an essential services in any scheme of quantity production on an interchangeable basis. A gauge . (or Limit Gauge). is a tool or instrument to measure or compare a component.. It is employed in the sense of an instrument which having fixed dimension, is used to determine whether the size of some component exceeds or is less than the size of the gauge itself . OBJECTIVES/RATIONALE. A neoplasm is an abnormal growth of tissue that may be benign or malignant. The student will identify terms related to neoplasia, classifications of tumors, and grading and staging of cancer.. Today’s Frontier. CNS Neoplasia- -Dogs. Common Types. Meningioma. Astocytoma.

(e.g. oranges, U.S. T-Bills, Currencies, ...) for cash immediately.. Lecture 06. Thomas Herring. tah@mit.edu. . Issues in GPS Error Analysis. What are the sources of the errors ?. How much of the error can we remove by better modeling ?. Do we have enough information to infer the uncertainties from the data ?. normal cervical squamous epithelium.  at the left, but . dysplastic squamous epithelium.  at the right. Dysplasia is a disorderly growth of epithelium, but still confined to the epithelium. Dysplasia is still reversible.. . suud. . khalifa. Learning objectives:.

Most . benign tumors grow slowly . & most of cancers grow faster . & eventually spread locally & to distant sites (metastasis) & causing death.. In some exception, some benign tumors grow more rapidly than some cancers e.g. leiomyoma (uterine fibroid), which is benign smooth muscle tumor influence by estrogen & so increase in size during pregnancy.. infection in colorectal carcinogenesis.
