Improved electrode paste provides reliable measurement of galvanic skin response

High-conductivity electrode paste is used in obtaining accurate skin resistance or skin potential measurements. The paste is isotonic to perspiration, is nonirritating and nonsensitizing, and has an extended shelf life

Rugged pressed disk electrode has low contact potential

Pressed-disk electrode with low contact potential monitors physiological processes. It consists of silver and silver chloride combined with bentonitic clay. The clay affords a surface that permits use over extended periods without contact deterioration

Improved electrode gives high-quality biological recordings

To obtain high quality waveforms from a subject engaged in physical activity, an improved electrode assembly has been devised. This consists of a cup containing an electrically conductive paste and a silver electrode. The paste maintains contact between the skin and the plate

An experimental investigation of the condensation of silicate grains

Amorphous magnesium silicate smoke particles were condensed from hydrogen and argon atmospheres containing Mg and Si0. A wide range of initial compositions were observed but all particles could be recrystallized into forsterite (Mg2Si04), by heating to 1000 C in vacuum. The amount of smoke formed decreased rapidly with temperatures between 300 and 800 K at reactant partial pressures of about 1 torr

Policy-induced Internal Migration: An Empirical Investigation of the Canadian Case

We investigate the influence of public policy on interprovincial migration in Canada using new aggregated migration data for 1974-1996, the longest period studied so far. We consider the consequences of regional variation in a variety of policies, and also investigate the effects of certain extraordinary events in Quebec and in the Atlantic provinces. The results indicate that while the changing bias in the unemployment insurance system may have induced some people to move to the relatively high unemployment Atlantic region, the resulting flows are likely too small to have altered regional unemployment rates. In contrast, political events in Quebec in the 1970's and the closing of the cod fishery in 1992 appear to be associated with large changes in migration patterns.migration, regional disparity, public policy, unemployment insurance, conditional logit, taxation data

Business process re-engineering using a customised mapping model: a case study in a SME

Increasing customer expectations in terms of cost, quality and services, together with competition in global markets has placed a premium on effective internal business processes. Companies are investing to streamline internal workflows, reduce costs and improve efficiency by re-engineering their business processes. Various mapping tools, such as Process Mapping and Value Stream Mapping, have been widely used as the vehicle for leveraging these improvements. However, in isolation any individual tool is often insufficient to achieve the desired results. This article uses a case study approach to investigate a real business process re-engineering (BPR) project in a medium sized manufacturing and service company. Process improvement is carried out using a set of mapping tools that have been selected, simplified and combined for practice. It has been shown that human factors are also crucial to the success of a BPR project. The case study illustrates the success of BPR with real practical examples of what works. Benefits include: increasing stock accuracy from 22% to above 95%; a reduction from about 40 reversed orders per month to zero, order fulfilment time reduced by 50%, and profitability improved 3 times at the end of the project. Non-quantifiable benefits include the elimination of a need for corrective actions, employees are more motivated, and the business stream is flowing smoothly allowing other business processes perform efficiently without disturbance
