Grassland management on organic farms
|Recent decades have seen a reduction in value of clover pasture with the ease of establishing and maintaining nitrogen fertiliser-based grassland pastures. However, clover based pastures are now seen as suitable for maintaining good stocking rates, and this 16-page document |

PURPOSE: A simple Excel-based workbook with worksheets as a front end for the AT&T GraphViz Graph Layout software suite. BioGrapher enhances Excel-based tools developed in the Chemistry and Biology Departments at Beloit College to allow for convenient visualization of graphs and graphical connections that are important
in systems and computational biology, molecular biology, biochemistry, and genetics.
This software can be used to investigate common molecular biology laboratory procedures using DNA or protein sequence data. These simulations and cases are based primarily on genetic and infectious disease with techniques such as: DNA electrophoresis, Southern blot, PCR, Multiplex PCR, Dot blot, ELISA, Western blot, 96-well PCR, protein electrophoresis.
Case It! is collaborative BioQUEST project between the University of Wisconsin-River Falls and Michigan State University.
Essential Physics I
Essential Physics 1, is an intensive introduction to classical and special relativity, Newtonian dynamics and gravitation, Einsteinian dynamics and gravitation, and wave motion. Mathematical methods are discussed, as needed; they include: elements of differential geometry, linear operators and matrices, ordinary differential equations, calculus of variations, orthogonal functions and Fourier series, and non-linear equations for chaotic systems. The contents of this book can be taught in one seme
Social Psychology - Spring 2008
Social Psychology - Spring 2007. The course will begin with a historical introduction to social psychology, focusing on the intellectual contribution of Kurt Lewin and the integration of
evolutionary and cultural approaches to human nature. The course will then focus on the major topics of social psychology (group dynamics, social influence, attitudes and attitude
change, social perception) as well as more specific areas of research (altruism, emotion, justice) and recent developments in the fie
A Look at Me
Students will develop a personal lifeline which will include events from the past and present. Students will also be asked to think or dream about events in the future. Advise students that for this activity they can plan to live to be one hundred years old. They must include a minimum of five events from their past and seven events they see in their future.
This curriculum contains suggested activities to gradually move students toward a more futuristic and empathetic mind set. Students may dis

Sustainable development needs chemical research
Research and innovation are preconditions for the transformation of economic and social processes in favor of a sustainable development. Chemistry, the science and practice of the transformation of matter, is of central importance. Everyone dealing with chemistry can contribute substantially to sustainable development and holds special responsibility. Already in education the links between reactions and substances with the consumption of energy and

It's a natural reaction to be frightened of some insects. Many insects have the ability to harm people, and many insects look very menacing. However, many large insects are not harmful at all. Because it would take several volumes to describe every insect, this publication is intended to distinguish several common insects and insect relatives in Kentucky that are or are not harmful.
Medical genetics involves the application of genetic principles in the practice of medicine. The material in this course encompasses diagnosis and treatment of genetic diseases (such as cancer genetics ), study of inheritance of diseases in families, mapping of disease genes to their chromosome locations, study of the molecular genetics and pathogenesis of inherited disorders, provision of genetic counseling for families, and investigations of methods for gene therapy. Unlike any other field, ge
The importance of the kidneys is most clearly demonstrated in the presence of pathophysiologic states. The kidneys play a central role in the maintenance of the internal milieu by balancing fluid, electrolytes, and hydrogen ions to provide optimal conditions for molecular, cellular, and body system function. They also serve as the major excretory organ for metabolic byproducts, drugs, and other organic substances. Finally, the kidneys are an important endocrine organ, producing vasoactive factor
Calculating Molecular Weight
The molecular weight is the mass of one mole of a substance. Usually, the units used for this are grams per mole. In this movie, we show how to calculate the molecular weight of a substance from the atomic weights given on the periodic table. On another page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).
Finding the Empirical Formula from a Molecular Formula
Elemental analysis is a useful qualitative analysis technique since it allows us to check if a sample is consistent with a given molecular formula. For instance, suppose we believe our sample is benzene (C6H6). We can compare the following:The empirical formula (CH) obtained from the molecular formula of benzene (C6H6); The empirical formula obtained from a elemental analysis of the sample. If the two empirical formulae do not agree, then the sample is not benzene. If the formulae agree, then ou
Finding Empirical Formula from an Elementary Analysis
On another page, we discuss how to obtain the empirical formula from a given molecular formula. Here, we consider how to obtain the empirical formula from an elemental analysis of a sample. Remember that comparing the empirical formula obtained from an elemental analysis with that from a molecular formula tells us if the sample is consistent with the molecular formula.
We are now ready to pull everything we know about reaction stoichiometry together, and answer the question: Given some initial amount of reactants, what should be present after a chemical reaction goes to completion? The procedure for answering this question is often called the "limiting reagent problem." You'll see why this name is appropriate in the following video.
You and a friend are hiking the Appalachian Trail when a storm comes through. You stop to eat, but find that all available firewood is too wet to start a fire. From your Chem 106 class, you remember that heat is given off by some chemical reactions; if you could mix two solutions together to produce an exothermic reaction, you might be able to cook the food you brought along for the hike. Luckily, being the dedicated chemist that you are, you never go anywhere without taking along a couple chemi
