This Test Guideline describes the determining of the ultraviolet-visible (UV-VIS) absorption spectrum of a chemical compound to have some indication of the wavelengths at which the compounds may be susceptible to photochemical degradation. Degradation will depend upon the total energy absorbed...

This dataset comprises trade in value added indicators for the most recent years, estimated using now-casting techniques. This approach estimates national input-output tables by projecting relationships observed in the latest TiVA benchmark year (currently 2011) into nowcast years (currently...

Nominal gross domestic product (GDP) is GDP given in current prices, without adjustment for inflation. Current price estimates of GDP are obtained by expressing values of all goods and services produced in the current reporting period. Forecast is based on an assessment of the economic climate...

This Test Guideline is designed to assess the toxicity of substances to freshwater aquatic plants of the genus Lemna (duckweed). Exponentially growing plant cultures of the genus Lemna (Lemna gibba and Lemna minor usually) are allowed to grow as monocultures in, at least, five concentrations of...

This Test Guideline describes the procedure for the electronic determination of pH of an undiluted aqueous solution or dispersion, the pH of a dilution of a solution or dispersion in water, or the pH of a chemical diluted to end-use concentration. It also describes procedures to determine acid...

What does PISA actually assess? This book presents all the publicly available questions from the PISA surveys. Some of these questions were used in the PISA 2000, 2003 and 2006 surveys and others were used in developing and trying out the assessment. After a brief introduction to the PISA...

The current monetary policy framework in several Latin American countries, combining inflation targeting and a floating exchange-rate regime, has contributed to disinflation by anchoring expectations around low, stable levels. This paper uses co-integration analysis to estimate simultaneously a...
