Signature …………………….………………………………………………………………… Global warming: Carbon-nutrient interactions and warming effects on soil carbon dynamics ABSTRACT In order to predict how terrestrial ecosystems will respond to global change, there is growing recognition that we need to better understand linkages between plant and soil processes. Previously the factors and processes with potential to influence the terrestrial carbon (C) cycle have been investigated in isolation from each other. This study investigated the interactions of nutrient availability and warming in controlling the soil carbon dynamics, with regards to the fate of already sequestered carbon in soil, under conditions of increasing atmospheric temperatures. The project objectives were addressed by three independent experiments designed to explain specific components of the carbon-nutrient cycle interactions, and the findings brought together to describe the implications for future soil carbon storage. The main measurements collected throughout this project included soil carbon dioxide (CO2) fluxes, partitioned into autotrophic and heterotrophic components, net ecosystem exchange and respiration fluxes, and background soil moisture and temperature data, backed by gas, soil and biomass analyses. -

Testing of Metal Volumetric Standards
3. t/ •/ ; Science Docs. NBS MONOGRAPH 62 Testing of Metal Volumetric Standards U.S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS THE NATIONAL BUREAU OF STANDARDS Functions and Activities The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950. These include the develop ment and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scientific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau's research are published either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau itself publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Technical News Bulletin presents summary and preliminary reports on work in progress; and CRPL Ionospheric Predictions provides data for determining the best frequencies to use for radio communications throughout the world. -
Science and Technology in Society (SATIS) Book 4
SATISNo. 410 Glass Teachers' notes i Glass Contents: Reading, questions and optional practical work on the manufactUre, uses and recycling of glass. Time: 2 periods (more if glass is made ). Intended use: GCSE Chemistry and Integrated Science. Links with work on sodium carbonate, calcium carbonate and silica. Aims: • To complement work on carbonates • To show something of the technology of glass manufacture and fabrication • To develop awareness of the many uses of glass, and the problems and opportunities involved in recycling it • To provide opportunities to practise skills in reading, comprehension, the application of knowledge, and certain practical skills. Requirements: Students' worksheets No. 410. A selection of items made from glass would be a useful aid. Requirements for the optional practical work are given later. If the optional practical work making glass is to be used (see below), it is suggested that it should precede the use of the students' worksheets. ( Making glass in the laboratory It is simple and rewarding to make glass in the school laboratory . Making soda glass requires i~practically high temperatures, but lead borate glass can be made at bunsen burner temperature. The experiment could be done as a class practical, though in view of the relatively large quantities of lead oxide involved teachers may prefer to demonstrate it, unless the laboratory has excellent ventilation facilities. Method 7.5g lead(II) oxide, 3.5g boric acid and 0.5g zinc oxide are placed in a I?lastic bag and thoroughly mixed. CARE: The mixture is poisonous. The mixture is heated strongly in a porcelain crucible on a pipeclay triangle. -
Outbreak! Scenario-Based Instruction in Microbiology

In this scenario-based learning (SBL) module, students will take part in a simulated epidemic and model the outbreak of an unknown pathogen. Through a six-part series of guided investigations, students will identify the “pathogen” responsible for the epidemic using simple microbiological assays and determine the best treatment to eradicate the pathogen. At ABLE, two of these activities were presented, as well as the development of this module. Firstpage1 Keywords: Infectious disease, synthetic epidemic, antibiotic testing, bacterial morphology, bacterial physiology Page 1 Spacer Introduction The Outbreak! module is a multi-part laboratory exercise cal situation and exposed to relevant issues, challenges and designed to provide students the opportunity to participate dilemmas.
