I develop and test models of the Big Bang, using observational data.

We have two pieces of observational evidence on the probability of life appearing.

A particularly important activity of SCN is the observational campaigns to remove virtual impactors.

So you go and find the paper, and what you find is an observational study.

More than 50 scientists then carried out coordinated observational campaigns to validate the results of the model.

Through a program of observational research, brainstorming new solutions and rapid prototyping, they've developed a completely new way to change shift.

The country reported that it possesses a vast weather observational network and is involved in regular data collection and databank management.

GOES 8 and subsequent GOES satellites (J M) are the prime observational platforms for dynamic weather and the near Earth environment for the 1990s and beyond.

The idea of establishing an international organization to ensure the coordination of NEO observational activities was put forward many times at the end of the 1980s.

(b) To promote study activities, at the theoretical, observational and experimental levels, of the physical mineralogical characteristics of minor bodies of the solar system, with particular attention to NEOs

(b) To promote studies, at the theoretical, observational and experimental levels, of the physical and mineralogical properties of minor bodies in the solar system, with particular attention to NEOs

The main goal of the Spaceguard Foundation, the coordination of the existing observational efforts for the discovery and follow up of NEOs, was achieved with the establishment of SCN.

For example, for a decade leading doctors advocated hormone replacement therapy to lower cardiovascular risk in post menopausal women. These recommendations, based on physiological and observational studies, proved profoundly misleading.

The most advanced observational and modelling tools, pollution prevention and control technologies and knowledge about best practices in air quality management must be shared effectively among industrialized and developing nations.

Many involve models. Regional fate and transport models can aid in the analysis of the observational data generated by the GMP, in particular with respect to the quantification of regional and global transport.

There have been several attempts to evaluate, through observational studies, the impact of screening in the general population. But such studies, which are based on comparisons between uncontrolled groups, tend to produce biased results.

That well implemented network and the timely transmission of the observational data by means of the Global Telecommunications System are essential in providing meteorological data for global weather analysis and prediction models and research.

The European Medicines Agency was more measured, saying in a statement, Based on this observational study alone, the risk cannot be associated with certainty to the growth hormone treatment. The results need to be confirmed and complemented with further analyses.

Physiological research on animals, or of human responses in laboratory settings, rank low on the hierarchy. Observational studies that compare outcomes for patients who receive particular treatments and control subject who do not rank higher, but may still be misleading.

In its third assessment report in 2001, IPCC reported that observational networks were declining in many parts of the world and that additional and sustained climate observations would be required to improve the ability to detect, attribute and understand climate change.

The atmospheric science community has made great progress in advancing and coordinating these complex observational networks and in applying them to study air pollution transport, map and assess pollutant emissions, develop air quality forecasting systems and support international policy formulation.

A network of 19 national tsunami focal points had been established to receive advisory information from the Pacific Tsunami Warning Centre and the Japan Meteorological Agency and existing observational networks had been upgraded to enable them to transmit real time information regarding tsunamis.

With observational studies producing inadequate results, scientists turned to a procedure developed years ago to evaluate new tuberculosis drugs randomized screening trials. Such trials begin with the selection of women at risk of developing breast cancer, and randomly allocate them to be screened or not.

Observational work in the thermal infrared spectral region with telescopes such as Keck and the National Aeronautics and Space Administration (NASA) of the United States of America Infrared Telescope Facility, both on Mauna Kea in Hawaii, and the NASA Spitzer Space Telescope currently represents one of the major areas of activity.

In anticipation of the collision of the comet with Jupiter, the Divisions of Astronomical Sciences and Atmospheric Sciences within the NSF and the Solar System Exploration Division of NASA sponsored a special program to support observational and theoretical investigations into the mechanism of energy deposition into different regions of Jupiter apos s atmosphere.

Nonetheless, they have led to important developments, because the negative results have ruled out some plausible hypotheses. And, though researchers may not have found results supporting any one theory, they have advanced the cause of science by better defining the observational criteria any quantum theory of gravity will have to take into account.
