It was probably not appreciated by the drafters of the bill that it would be very difficult to get scientists and engineers employed in industry to come forward with information on public policy concerns in the absence of some protection for their livelihoods. 

Filipovic has worked hard to break down barriers for women in the fields of engineering and business. In 1974, she became the first female professional engineer employed by a major chemical producing company. The National Museum of Science and Technology in Ottawa, Ontario, has featured her work as part of an exhibit on women inventors. 

The microscopic world of atoms is difficult to imagine, let alone visualize in detail. Chemists and chemical engineers employ different molecular modelling tools to study the structure, properties, and reactivity of atoms, and the way they bond to one another. Richard Bader, a chemistry professor at McMaster University, has invented an interpretative theory that is gaining acceptance as an accurate method to describe molecular behaviour and predict molecular properties. According to Dr. Bader, shown below, small molecules are best represented using topological maps, where contour lines (which are commonly used to represent elevation on maps) represent the electron density of molecules. 

There is no detailed documentation of the number of chemists and chemical engineers employed in the nuclear power industry. Within AECL there are 300 in a total staff of 6000 (5%). Within Ontario Hydro (26) there are approximately 145 in a total staff of 3300 associated with nuclear power generation (4.4%). The Canadian Nuclear Association (CNA) estimates that in 1976 there were about 18,400 people employed in the Canadian nuclear industry, excluding the uranium industry (27) If about 4% of these were chemists or chemical engineers, one can estimate that a total of about 700 were employed in the industry at that time. There is likely to be considerable expansion of the industry by 1985, particularly in the utilities such as Ontario Hydro, Hydro Quebec, and New Brunswick Power which already have additional nuclear capacity under construction. The expansion will in turn provide new opportunities for members of this profession. 

Explosion Properties. Occurence of detonation within rocket engines employing certain aminated fuels and nitric acid propellants are related to the formation of amine or hydrazine nitrates which tend to decompose explosively under the influence of sudden temp or pressure rises (Ref 51). Tangential-mode rocket motor instabilities were analyzed using 1-dimensional, 2-phase... 

Jeff is a talented Staff Engineer employed by a major chemical plant in West Virginia he has a solid background in Loss Prevention. Jeff Josecks article was written to spark interest and discussion of process safety in safety meetings. It is also very skillfully worded to spark the readers into thinking about acceptable risks and minimal risks. 

Although the allowable velocity given by Eq. (1) may be conservative for many types of operations while Eq. (3) is somewhat less conservative due to the use of the active or bubbling cross-sectional area of the tower along with the other corrections, many engineers employ vapor velocities in the range of 65 to 80 percent of Vm or to make certain their column will be operable. The... 

Chemical engineering employs a systemic approach that guarantees each step in the long process, from concept to commercialization, is creative and taken with care. However, the rapid pace and competitive frenzy is placing the very industry in jeopardy. Products and services are often conceived of as commodities today. Price has become the easiest, and therefore the preeminent, decider. 

An engineer employs lines to depict features of the possible movements of machinery. To an untrained observer, schematic illustrations seem static, providing a still-life vision of a bulky device. But literate viewers can apprehend movement from such diagrams. An attentive observer anticipates how our perceptions would change from the possible movement of objects. When rendered in two dimensions, the lines of an engineer s design plan he between exposed surfaces and hidden ones, from the reader s perspective. 

As the foregoing examples illustrate, the special stereochemistry of the icosahedral carboranes can be used to advantage in the synthesis of structurally novel molecules. Molecular engineering employing non-icosahedral carborane or organoborane units is also under active investigation, as in stacked assemblies that incorporate 7-vertex... 

That such notions are not merely a reflection of the protectionist approaches of professional interest groups is indicated by the expression of similar concerns by the Engineering Employers Federation (EEF), which according to Allen (2004 9) noted in response to the Consultative Document on the OEL framework, that ... 

The effectiveness factor E is expressed in terms of the intrapellet Damkohler number, and the chemical reaction time constant co is the inverse of the best pseudo-first-order kinetic rate constant. The reactor design engineer employs an integral form of the design equation to predict the length of a packed catalytic tubular reactor Lpfr that will achieve a final conversion of CO specified by /final. The approximate analytical solution, vahd at high mass transfer Peclet numbers, is...
