Technologists working with

The aim of every technologist working with food dispersions or food colloids is to be able to select the proper amphiphile for a desired application or, even better, to be able, to design a good blend of emulsifiers and/or stabilizers to achieve the desired stability, texture, rheological properties, and other important characteristics. The aim of the scientists is to provide a good understanding of surfactant activities and capabilities and to be able to predict chemical structure and correlate with surface reactivity. 

The equilibrium in these systems above the cloud point then involves monomer-micelle equilibrium in the dilute phase and monomer in the dilute phase in equilibrium with the coacervate phase. Prediction o-f the distribution of surfactant component between phases involves modeling of both of these equilibrium processes (98). It should be kept in mind that the region under discussion here involves only a small fraction of the total phase space in the nonionic surfactant—water system (105). Other compositions may involve more than two equilibrium phases, liquid crystals, or other structures. As the temperature or surfactant composition or concentration is varied, these regions may be encroached upon, something that the surfactant technologist must be wary of when working with nonionic surfactant systems. 

The European Industrial Gases Association working with the Compressed Gases Association of America and the International Association of Beverage Technologists has prepared a specification for liquid carbon dioxide for use in foods and beverages. This is shown as Table 7.1. It is to this minimum standard that all carbon dioxide to be delivered to soft drinks and aerated mineral water bottles is manufactured. 

It is easy to overlook the fact that while particular facts and ad hoc correlations may be no more than awkward or intriguing to a scientist, they may be quite sufficient to permit an engineer or technologist to take an important step conversely generalization, essential to science, may be a feeble prop for the practitioner. The literate and sophisticated engineer, like Watt, may enjoy his use of scientific labels and his mastery of scientific rationalization while always actually working with particular facts and ideas. Any scientific theory may envelop his actual immersion in particulars.42...

One such possibility consists in the acceleration of contaminant hydrolysis. Hydrolytic detoxification in an alkaline medium is known to be several orders of magnitude faster than that in a neutral medium. Therefore, one can cover underwater places of contaminant burial with any solid alkaline reagent, which will create an alkaline medium in the zone of the contaminant s location. Requirements for such a reagent are rather simple. It should be very poorly soluble in sea water, have a considerable specific surface area (no less than 50 m /g), display clearly defined alkaline properties and be a nontoxic, low-priced, and easily available substance. I believe that chemists-technologists working in the fields of silicate industry, metallurgy, and absorption processes already understand that a wide variety of well-known materials, including some industrial wastes, comply with the above requirements. 

Membrane technologists are well aware that the most permeable glassy polymers are those which possess a very high free volume, where the term free volume refers to the intermolecular voids within a material [1], Scientists who work with molecular sieves, such as zeolites, commonly use the term microporous material to describe those materials which contain pores or channels less than 2nm in width, a definition that arises in the context of gas adsorption studies [2],... 

Within industry, we generally try to determine what an individual knows, how an individual can contribute, the perspective an individual brings to us, and how well the individual fits into the culture of our organization. We often do not hire high-powered technologists who don t exhibit the people skills to fit into our team environment, or whose perspective scans to be limited to a narrow technical field. We want deep technical expertise, but that expertise must have a context, and the individual needs to be able to work with others. In an interview, I often ask behaviorally oriented questions, such as, From your educational experiences, tell me specifically about a time when you had to ... 

The book is intended for engineers, scientists, and technologists who are interested in or working with reactive extrusion, but it can also be used as a textbook for courses on this subject. The main objective is understanding the complex interactions that make reactive extrusion work. In this book we take a practical point of view, avoiding lengthy calculations and theoretical derivations that are not relevant to applications and can be found elsewhere. 

Other careers in veterinary science requiring less study and training are those of veterinary technician (two-year program) or technologist (four-year program). Veterinary technicians and technologists work in clinics and in research facilities. They assist veterinarians with animals in the examination room and in the surgical room and are responsible for the daily care of hospitalized and laboratory animals. They also perform laboratory procedures, keep records, and assist with client education. 

Upon first glance, it may appear this chapter is oversaturated with technological details that would be of interest only to technologists working in hyaluronan production. However, the material is presented in this way intentionally in order to properly elucidate the difficulties of hyaluronic acid production and the potential problems caused by the technological impurities in the final product when intended for medical application. 

One cannot consider the subject of flavor creation (imitation would perhaps be a better word as the term creation more correctly applies to abstract perfumes than to flavors) in the laboratory without first examining the type of persons who carry out this work (i.e., in the flavor industry the flavorist in food and related industries the flavor technologist), the environment of a flavor laboratory, and the functional interfaces which influence the development of a successful flavoring product. This discussion will be centered on the flavor industry but much can be applied to technologists involved with the flavor of consumer products.

The subject of health and safety is interdisciplinary and poses numerous challenges. Whilst many specializations may interact to provide solutions, the background and experience of the rubber technologist can provide the fulcrum of effective action. Many of the hazards in the rubber industry have their roots in the rubber and its unique characteristics such as its tack, friction, susceptibility to chemical change and its reluctance to wet and accept additives without high energy inputs. Those who work with rubber not only experience its problems but are in a unique position to contribute to the solutions required.
