AFP: Solved And Unsolved Problems [MJM 1996 2: 127-134]
AlphaFetoprotein (AFP) Solved and unsolved problems.
http://www.med.mcgill.ca/mjm/v02n02/afp.html

Extractions: Alpha-Fetoprotein (AFP): Solved and Unsolved Problems G.I. Abelev , Ph.D ., and N.L. Lazarevich HISTORICAL OVERVIEW The protein that would later be called alpha-fetoprotein (AFP) was first identified in human fetal sera by Bergstrand and Czar in 1956 on paper electrophoregrams (1). Several confirmations of this finding were made, but the potential role of the protein remained entirely unknown. In 1960, the present authors found an antigen in mouse hepatoma cells that was absent from the liver, blood, and other tissues of normal adult mice. However, the relationship of this antigen to a feto-specific serum protein was only established, unexpectedly, during the course of other study on antigenic maturation of mouse liver in ontogenesis. The next few years brought very broad confirmation and extension of the first clinical observations, with early demonstration of the value of the AFP test in monitoring surgery and chemotherapy, primarily in GCT (8). Very active parallel investigations were carried out on rat and human AFP by Uriel et al. in France. Several highly sensitive methods for AFP detection were elaborated in the early 1970's (9), but the most practical, both in experimental systems and in clinics, was found to be radioimmunoassay (RIA), first introduced by Ruoslahti and Seppala. This assay permitted the detection of AFP from its background level to its maximal values in different pathologies (10). Later, RIA was supplanted by enzyme-linked immunoenzyme assay (ELISA), which is identical to RIA in specificity and sensitivity but more stable and ecologically acceptable. AFP ELISA kits produced by a number of companies are routinely used at present in clinical work throughout the world.

Introduction to SUP Concept SUP Management Critical Reflections Image - child sucking single noodle from a plate of sphagetti. Conceptually the task is simple. Find something of interest and pursue it. The pursuit requires you to interact with the world around you. As you explore aspects of this interest, you inevitably find problems and create questions and from those problems you build collections of answers and more questions. Four steps are noteworthy here: problem discovery, problem mapping, solution discovery, and solution mapping. Of these, only problem mapping lacks a parallel more formal structure in computer networks. A possible solution to this missing structure within computer networks will be discussed. This essay is a primer for problem mapping, creating structures that stimulate, track and manage the creation of problems (questions) and their eventual answers. In turn, this engine for thought can be applied to any content area. To address problem mapping, I propose a new construction called SUP (Still Unsolved Problems).

Extractions: There are very many unsolved problems in Russia, but the movement in the right direction can be clearly seen. This gives a certain confidence in the correctness of what we are doing, said Russian President Vladimir Putin in an interview he gave to the London Financial Times in the runup to his visit to Great Britain which is scheduled for December 21-22. "We do not ask to write off our debts, we are paying them," to the International Monetary Fund - even before the expiration of the date, pointed out the President. We are developing market institutions and are striving to enter the World Trade Organisation, "we are very actively carrying out economic reforms," and have paid the main debts to the population. The real incomes of the pensioners have gone up by 22 percent, the wages - approximately by 19 percent, the real per capita incomes - by 6.5 - 7 percent. The growth of the Gross Domestic Product this year will amount to 5.7 percent, said Vladimir Putin. This year, continued the President, investments, both internal and foreign, were considerably increasing - with foreign investments growing more rapidly. But in order to make our economy more attractive, much yet have to be done, underscored President Vladimir Putin. With this aim in view we have envisaged a whole package of measures. We shall continue our persistent and liberal tax policy. The income tax in our country is the lowest in Europe - only 13 percent, the profit tax will be 24 percent. "We have practically brought to nought the sales tax and the turnover tax, have taken a number of measures for de-bureaucratisation and liberalisation of the economy. The number of types of the activity to be licensed have decreased from 2,000 to slightly more than 100," pointed out the President.

http://books.cambridge.org/0883853159.htm

Extractions: Pure Mathematics In stock Only for sale in Australia, United Kingdom, Ireland, New Zealand, South Africa, United States of America Victor Klee and Stan Wagon discuss some of the unsolved problems in number theory and geometry, many of which can be understood by readers with a very modest mathematical background. The presentation is organized around 24 central problems, many of which are accompanied by other, related problems. The authors place each problem in its historical and mathematical context, and the discussion is at the level of undergraduate mathematics. Each problem section is presented in two parts. The first gives an elementary overview discussing the history and both the solved and unsolved variants of the problem. The second part contains more details, including a few proofs of related results, a wider and deeper survey of what is known about the problem and its relatives, and a large collection of references. Both parts contain exercises, with solutions. The book is aimed at both teachers and students of mathematics who want to know more about famous unsolved problems. This is a book that not only belongs in every university, college, and high school library, it very definitely belongs in every public library.Mathematical Reviews

At the main train station, an African-American heading south had to sit in a separate, blacks-only section. A trip north meant sitting anywhere. Cincinnati today is still a community at a crossroads, a city grappling with race problems that have simmered for decades.

Its A Puzzlement - Unsolved Problems In Number Theory
It's a Puzzlement unsolved problems in Number Theory. by John P. RobertsonThere are thousands of unsolved problems in number theory.
http://www.casact.org/pubs/actrev/aug97/puzzle.htm

Extractions: Unsolved Problems in Number Theory by John P. Robertson There are thousands of unsolved problems in number theory. One famous open problem is due to Goldbach: prove or disprove that every even integer greater than 2 is a sum of two prime numbers. A less well-known problem is that of Egyptian fractions: determine whether every fraction of the form 4/ n n i j k Despite the fact that there are so many unsolved problems, Gary Venter continues to offer new problems. Here are two. The first is to investigate sequences of consecutive positive integers where each term is a product of two or more two-digit numbers (not necessarily primes). For example, 322, 323, 324, 325 give four such consecutive integers (322=14x23, 323=17x19, 324=18x18, and 325=13x25). What is the longest sequence you can find? In his second problem, Gary noted that if n =12 (or 36, or 156) then ( n n +2)/2, and ( n +3)/3 are all prime. What is the largest k you can find such that there is an n with ( n n n +k)/ k all prime?

Extractions: The Greatest Unsolved Problems in Science (Please come back periodically as information will be added from time to time) A lot about the world has been learned during the past few centuries, but some mysteries still remain. Apparently, Nature has not revealed to us all her secrets but scientists are hard at work trying to decipher them. On August 28, 1999, National Public Radio's Science Friday program presented some of the greatest unsolved problems in science. Here is Jupiter Scientific's list. More detailed information will be provided in the coming months, so come back and find out more. What Is Dark Matter?
