• ### The William Lowell Putnam Mathematical Competition 1985–2000 Problems, Solutions, and Commentary

The William Lowell Putnam Mathematical Competition is the premier undergraduate mathematical competition in North America. This volume contains problems from the years 1985-2000, with solutions and extensive commentary. It is unlike the first two Putnam volumes and unlike virtually every other problem-based book, in that it places the problems in the context of important mathematical themes. The authors highlight connections to other problems, to the curriculum, and to more advanced topics.

• ### What Is Water Pollution? * Monty C. Dozier Assistant Professor and Extension Water Resources Specialist

Having identified and classified relevant water pollution problems, and having assigned priority to them, the next step is to identify appropriate interventions to cope with the problems. For every problem identified, therefore, an assessment should be made of the most appropriate means for intervention. Furthermore, an indication should be given of the relevant administrative level(s) to be involved. The proposed interventions may vary significantly in detail and scope.

• ### Project Gutenberg’s Mathematical Recreations and Essays

Most of the open questions discussed by the author were settled during the twentieth century. The author’s footnotes are labelled using printer’s marks*; footnotes showing where corrections to the text have been made are labelled numerically1. Minor typographical corrections are documented in the LATEX source. This document is designed for two-sided printing. Consequently, the many hyperlinked cross-references are not visually distinguished. The document can be recompiled for more comfortable on-screen viewing: see comments in source LATEX code....

• ### Báo cáo khoa học: "A Noisy-Channel Approach to Question Answering"

We introduce a probabilistic noisychannel model for question answering and we show how it can be exploited in the context of an end-to-end QA system. Our noisy-channel system outperforms a stateof-the-art rule-based QA system that uses similar resources. We also show that the model we propose is flexible enough to accommodate within one mathematical framework many QA-specific resources and techniques, which range from the exploitation of WordNet, structured, and semi-structured databases to reasoning, and paraphrasing.

• ### Hepatitis and Liver Cancer: A National Strategy for Prevention and Control of Hepatitis B and C

Another limitation of the literature is that minorities have been dramatically under- represented in psycho-oncology research (Anderson, 1992). Further, although the research demonstrates the importance of the spousal relationship during the cancer experience, there is a lack of controlled research concerning couples or family interventions. Finally, a crucial question that remains unanswered is determining what these findings mean in terms of clinical intervention and care.

• ### Assessment for the california mathematics standards: Grade 4

By the end of grade four, students understand large numbers and addition, subtraction, multiplication, and division of whole numbers. They describe and compare simple fractions and decimals. They understand the properties of, and the relationships between, plane geometric figures. They collect, represent, and analyze data to answer questions.

Do as many as you can, then come back to the others in the time you have remaining. Note: Unless otherwise noted, all of the following should be assumed. 1. Illustrative figures are not necessarily drawn to scale. 2. All geometric figures lie in a plane. 3. The term line indicates a straight line. 4. The term average indicates arithmetic mean....

• ### TRADE ENTRANCE EXAM Study Guide

For every exam it is important to calculate the amount of time you can spend on each section or question according to the number of marks it is worth. (Do the easy questions or sections first - this is helpful for calming nerves and establishing your concentration.) If your exam is all multiple choice, you may want to note where you should be after one hour and after two hours to ensure you aren't falling too far behind. It is important to work at a fairly quick pace; multiple choice exams are notorious for being long....

• ### ATMOSPHERIC AEROSOLS – REGIONAL CHARACTERISTICS – CHEMISTRY AND PHYSICS

The most important trend in biological engineering is the dynamic range of scales at which biotechnology is now able to integrate with biological processes. An explosion in micro/nanoscale technology is allowing the manufacture of nanoparticles for drug delivery into cells, miniaturized implantable microsensors for medical diagnostics, and micro-engineered robots for on-board tissue repairs. This book aims to provide an upto- date overview of the recent developments in biological engineering from diverse aspects and various applications in clinical and experimental research....

• ### THE MATHEMATICAL THEORY OF NON-UNIFORM GASES

The atomic theory of matter asserts that material bodies are made up of small particles. This theory was founded in ancient times by Democritus and expressed in poetic form by Lucretius. This view was challenged by the opposite theory, according to which matter is a continuous expanse.

• ### The Logic of Individual Choice: The Foundation of Supply and Demand

Economists have an answer to the question of why people behave as they do — self interest. Economists' analysis of individual choice does not deny individual differences. A good beginning in understanding individual choice is to focus on the rational part of people's behavior.

• ### DIABETIC RETINOPATHY

General symptoms include morning stiffness of more than 60 minutes, fatigue, sometimes even slightly elevated temperature, but the main initial symptom is low back pain at night and in the morning. All patients with low back pain should be questioned about a positive family history concerning rheumatic diseases, as the risk of developing this illness is higher in patients where family members already have been diagnosed with ankylosing spondylitis.

• ### Delivering the goods: rethinking humanitarian logistics

This issue of Forced Migration Review is about improving communications between logisticians and programme managers to make such mix-ups a thing of the past. We are grateful to the Fritz Institute for drawing our attention to the importance of humanitarian logistics and for the very generous grant which has made this issue possible. We are deeply indebted to our Guest Editors, Anisya Thomas (Fritz Institute's Managing Director) and Ricardo Ernst (Georgetown University), and to Lynn Fritz for his personal support.
