An essay by Hannah Ellis -00It starts with a question, perhaps a passing interest. Design takes over a city, with clutters of exhibitions in galleries and disused spaces working loosely in response. New biennials and festivals and weeks emerge every year. Old events happen again simply because they happened before. What is it that these events and their predictable patterns actually achieve, though?00For almost 200 years, continuing a line of thought first started by events like the Great Exhibition, ?design events? have become more and more popular across Europe, tangling around local, national, and international politics and economics. But can design be important or meaningful at this kind of scale? And how do these events act on people and places ? as well as on the discipline itself? With the pause that the pandemic offers, is this the moment to examine who and what they exclude, taking the time to imagine what they could be instead?0--0Hannah Ellis is a designer, writer and educator based in London (UK).

Contains all the formal opinions and accompanying orders of the Federal Power Commission ... In addition to the formal opinions, there have been included intermediate decisions which have become final and selected orders of the Commission issued during such period.

"Within graphic design, the concept of systems is profoundly rooted in form. Starting from a series of design research residencies in the context of the Porto Design Biennale, this volume proposes a variety of perspectives--social, cultural, political--to challenge this deeply engrained tradition."--Publisher's description.

Due to the increasingly complex mineralogy, and lower grade of many current ore reserves, technology has, over the past decade, had to evolve rapidly to treat these materials economically in an industry which has undergone severe periods of recession. However, most of the technical innovations, such as the increasing use of solvent-extraction, ion-exchange etc., have been in the field of chemical ore processing, and, apart from the use of computers and ever larger unit process machines, there have been few major evolutionary changes in the field of physical mineral processing, where conventional crushing and grinding methods, essentially unchanged in half a century, are followed by the 'old-faithfuls'- flotation, gravity, magnetic and electrostatic methods of separation. Many of these techniques have major limitations in the treatment of 'new' ores such as complex sulphides, and the main purpose of the NATO Advanced study Institute (ASI) "Mineral Processing at a Crossroads" was to review the future of mineral processing. One of the great failings of physical methods is their inability to treat ultra-fine particles, and much research effort is required in this area. Flotation is still the most widely used and researched method for separating minerals, and is the only method which can be used to produce separate concentrates from complex sulphide ores. However, its performance on these 'modern' ores is poor, and it is in this area particularly that chemical methods will increasingly be integrated into plant circuits.

The last twenty years have seen major advances in the electronics industry. Perhaps the most significant aspect of these advances has been the significant role that electronic equipment plays in almost all product markets. Even though electronic equipment is used in a broad base of applications, many future applications have yet to be conceived. This versatility of electron ics has been brought about primarily by the significant advances that have been made in integrated circuit technology. The electronic product user is rarely aware of the integrated circuits within the equipment. However, the user is often very aware of the size, weight, mod ularity, maintainability, aesthetics, and human interface features of the product. In fact, these are aspects of the products that often are instrumental in deter mining its success or failure in the marketplace. Optimizing these and other product features is the primary role of Electronic Equipment Packaging Technology. As the electronics industry continues to pro vide products that operate faster than their predecessors in a smaller space with a reduced cost per function, the role of electronic packaging technology will assume an even greater role in the development of cost-effective products.
