Controlled Environment Specimen Transfer

Microscopy and Microanalysis, 2014
AbstractSpecimen transfer under controlled environment conditions, such as temperature, pressure, and gas composition, is necessary to conduct successive complementary in situ characterization of materials sensitive to ambient conditions. The in situ transfer concept is introduced by linking an environmental transmission electron microscope to an in ...

CONTROLLED‐ENVIRONMENT AQUACULTURE

Proceedings of the annual meeting - World Mariculture Society, 1974
ABSTRACTThe University of Arizona's work in controlled‐environment agriculture is reviewed, followed by discussions of their contemporary modifications of these techniques in controlled‐environment aquaculture. Open and closed systems of agriculture have been designed, constructed and operated by the University in desert regions of Arabia and North ...

Quality Control of Work Environments

American Industrial Hygiene Association Journal, 1971
As concern for environment increases, the impetus to apply more sophisticated quality control techniques to the work place environment will develop. Control concepts which are presented in this paper are applicable in industrial hygiene practice to a wide variety of situations; the examples presented vary in scale from vapor control at a single process

The Control Environment

1996
There is some confusion between understanding the importance of the control environment in which an organisation exists and dealing with accounting aspects, which are largely about presentation and form. It is important to distinguish between the two. In our view the more important area to focus on is the control environment because this provides the ...

Controlled environment transmission electron microscopy

Microscopy Research and Technique, 1998
The design of a controlled environment electron microscope is described and examples are presented to demonstrate the information that can be obtained by studying gas-solid interactions in real time and at high spatial resolution.

Controlled Environment Concepts

1991
In the last chapter we examined types, sources, and effects of contamination. We are now ready to begin to discuss how we may keep this contamination away from our sensitive materials, structures, and processes. It is perhaps worthwhile at this point to introduce the idea of the contamination pathway.

OoD-Control: Generalizing Control in Unseen Environments

IEEE Transactions on Pattern Analysis and Machine Intelligence
Generalizing out-of-distribution (OoD) is critical but challenging in real applications such as unmanned aerial vehicle (UAV) flight control. Previous machine learning-based control has shown promise in dealing with complex real-world environments but suffers huge performance degradation facing OoD scenarios, posing risks to the stability and safety of

Controlled-environment studies

1993
Studies of photosynthesis and plant productivity may require environmental control. This chapter outlines procedures for environmental control in structures such as growth chambers, glasshouses, and open-top chambers, for study with single plants and with canopies of plants. (See Chapter 9 for an outline of environmental control in leaf chambers.)
