Prototype development

Having outlined the product composition it is useful to calculate the approximate osmolality from published tables, for example in the CRC Handbook of Chemistry and Physics (CRC Press Inc.), The Merck Index (Merck Co. Inc.) and The British Pharmacopoeia (HMSO). Ingredients for which osmolality values are not available can be allowed for by using values for substances of similar molecular weight and ionic character. 

The approximation will show if major adjustments are necessary prior to bench work the value at this stage should be about 80% of the target level. A reduction in osmolality can be achieved by substituting low MW sugars with a maltodextrin or by reducing the total carbohydrate content. Similarly, an increase can be achieved by the opposite moves. 

A first prototype can then be put together with the decided carbohydrate system and with salts added to approximate to the target electrolyte levels. Sweetness must be adjusted, probably by adding non-nutritive sweetener(s), an acidity level must be selected and flavour, colour and preservative must be added at appropriate levels. If the drink is to be carbonated a level must be chosen (a low level is preferable). 

All the adjustments will contribute to the osmolality, which should be measured to assess what further fine-tuning will be required. It is important to measure the osmolality of the drink as presented to the small intestine, by which time carbonation will have been virtually eliminated.

The prototype developed by Lifetrac System (LifeTrac Systems, USA)59, also based on NIR spectroscopy, is very interesting and seems to satisfy the above-mentioned requirements. It is shown in Figure 11. In this case, it is not the light scattered back out through the skin that is detected, but rather... 

The third step, however, reminds us that we do have to pay attention to good software development practices if a generally used, and useful system is to result from the prototype. Development of a full system, based at least in part on the prototype, proceeds with detailed specifications as the system architects define and construct its final form. 

Overall, most of the requirements for a process spectrometer/analyzer are straightforward to implement, but they do require attention at the design level. Another important area, which is FTIR specific, is the user interface and the need to provide for industry standard data communications. Standard software packages do exist for process instrumentation. For prototype development, and even for the front-end interface in a stand-alone mode of operation, software products, such as National Instraments Lab View and the Mathworks MatLab, are also important instrumentation development tools. Note that National Instruments also provides important computer-based electronics and hardware that meet most of the computer interfacing, and system control and communications needs for modem instrumentation. For practical installations, a product known... 

With regard to low temperature fuel cells (PEM), efforts must be guided to materials development (catalysts, electrodes, electrolytes, plates, seals, etc), fuel cells components development and its manufacturing methods, fuel cells prototypes development, systems based in fuel cells for transport, stationary and portable applications, and fuel processors.

Moreover, an easy exchange of the detection capillary is possible. This feature is of enormous importance, because in the current status of prototype development cracking of the capillaries is a routine occurrence. 

Several techniques for miniaturization of simple chemical and medical analysis systems are described. Miniaturization of total analysis systems realizes a small sample volume, a fast response and reduction of reagents. These features are useful in chemical and medical analysis. During the last decade many micro flow control devices, as well as the micro chemical sensors fabricated by three dimensional microfabrication technologies based on photofabrication, termed micromachining, have been developed. Miniaturized total analysis systems (pTAS) have been studied and some prototypes developed. In microfabricated systems, microfluidics , which represent the behavior of fluids in small sized channels, are considered and are very important in the design of micro elements used in pTAS. In this chapter microfluidics applied flow devices, micro flow control devices of active and passive microvalves, mechanical and non-mechanical micropumps and micro flow sensors fabricated by micromachining are reviewed. 

More than a dozen drugs, almost all of them in use for many years, can be classified as neuroleptics. The phenothiazine derivatives were originally the most commonly used class of neuroleptic drugs. Chlorproma-zine is the prototype, developed in France and introduced into North America in 1953 by Heinz Lehmann. Its brand name in Canada and England is Largactil, and in the United tates, Thorazine. The antidepressant amoxapine (Asendin) is metabolized into a neuroleptic and has similar effects and, more important, adverse effects, such as tardive dyskinesia. All the classic neuroleptics block dopamine, but all of them also affect other neurotransmitter systems. 

This section will describe the typical stepwise process by which Softgels may be developed. The steps generally include fill formulation development, shell compatibility, prototype development (lab scale encapsulation), experimental batch manufacture (process development), clinical supply and conclude with a product performance review of the manufacturing process and specialized formulation approaches to enhance pharmacokinetic performance. 

Formulation and/or development of advanced drug-delivery systems such as microencapsulated molecules, transdermal patches, or liposomes are frequently accomplished in the laboratory. However, large-scale production of these dosage forms may be problematic because the same conditions of manufacture may not be attainable or desirable in the plant setting. Consultation with process development personnel during the finalization of the prototype development phase is one way of minimizing scale-up difficulties.

Rimom is an ontology matching prototype developed at Tsinghua University in Beijing, China (Li et al. 2009).

There are several methods for... 

Many of these tools have been developed through successful collaborations between researchers and industry. Clio, one of the first and most sophisticated schema matching tools, was a research prototype developed through a collaboration at IBM s Almaden Research Center and the University of Toronto [Miller et al. 2001], Clio can automatically generate a view to reformulate queries from one schema to another or transform data from one representation to another to facilitate data exchange. 

The prototype TFRT instrument consists of a thin-film resistive heater, two fans, thermocouple, controller, software, and a computer. The heating element has an effective face area of 15 x 15 mm and a resistance of 15 2 (Fig. 1A). The PCR capillaries are coupled directly to the heater. For cooling, two fans are positioned on opposite sides of the test section. The fans and the heating element are powered by 9VDC (see Note 1). The system temperature is sensed by a thermocouple (see Notes 2 and 3) mounted inside a capillary and mounted on the heater in a symmetrical fashion to the capillaries that hold the PCR mixtures. For prototype development, thermocouples were mounted in each of the capillaries to map the temperature distribution on the surface of the heating element. 

A thin-film electrode is relatively dense, as the metallic film does not have the electrocatalytic properties that a porous electrode has. Therefore, in many instances, the surface of the thin film is chemically or electrochemically modified to enhance its electrocatalytic activity. For instance, thin platinum film electrodes can be platinized electrochemically forming a porous platinum black layer. This platinum black layer is electrocatalytically more active than the thin platinum film. Thin-film processes are more capital and labor intensive and the process is more complicated than thick-film processes. Thin-film deposition is also a batch process which may produce sensors of limited numbers of silicon substrates. This is very desirable in prototype development, for it allows modification on prototypes with minimum cost.
