On January 28, 29, and 30, 1975, at the Americana Hotel in New York City,the American Association for the Advancement of Science and the manu-facturing community will join in presenting a technical exhibition un-precedented in the United States. For the first time, an exhibition willhave an entity of its own, in the manner of European exhibits such asAchema.

INTERSCIENCE INTERNATIONAL will have the following outstandingfeatures:

* The exhibits will be interdisciplinary and international in approach. Both theaudience and the exhibits will be greater in scope than ever before, a distinctadvantage to scientists and manufacturers.

* INTERSCIENCE INTERNATIONAL will take place concurrently with theannual meeting of the American Association for the Advancement of Science,which boasts over 130,000 members, but admission will not be restricted tomembers. Invitations will be extended to over 50,000 members of the greaterNew York scientific community, and any scientist may attend simply byregistering.

Because of these unique features of INTERSCIENCE INTERNATIONALand its advantageous location, an audience of 12,000 is expected for thethree-day exhibition.

Members of the scientific community are invited to send now for admis-sion badges. Instrument manufacturers interested in exhibiting shouldwrite to:

THE M-20. -_

WILD

The Wild M-20 is for all observation methods, and for all types ofillumination. With every useful accessory and attachment available,it does what you want it to do, when you want to do it.

Our new high-intensity 12vlOOw Quartz Iodine Single IlluminatorBase*'< now provides ample light for combined phase-contrast polar-ization, high power color photomicrography, darkfield fluorescence,and up to oil immersion.

The Wild M-20 is one microscope you don't outgrow. It grows withyou. A real budget saver, from the family of great Swiss optical in-struments for geodesy, photogrammetry and microscopy. Backed byfast, full factory services.

*UPDATES ALL WILD M-20, M-11 AND M-12 MICRO-SCOPES. MOUNTS PERFECTLY WITHOUT ADAPTATION.

MEN AT WORK: Applications ofErgonomics to Performance and De-sign by Roy J. Shephard, Univ. ofToronto, Onitario, Caniada. This bookhas the unifying theme of matchingdesign to human performance charac-teristics in the interests of both work-er-comfort and productivity. Wherepossible, material has been chosen forits broad interdisciplinary appeal, andwhile a sound scientific basis has beenpreserved, unnecessary technical termsare avoided. The psychological and thephysiological impact of the workingenvironment is noted, and psycholog-ical, physical and physiological aspectsof fatigue are discussed. The finalsection of this volume takes a detailedlook at specific ergonomic prob-lems-the aging and the handicappedworker; the underdeveloped nation;the application of anthropometry todesign; the nature of computers andtheir potential role in replacing theworker; and the ergonomics of masstransit systems. This book will appealto those who demand an answer toman's role in the complex machine-oriented world of the twentieth cen-tury. '74, 408 pp. (6 3/4 x 9 3/4), 99il., 8 tables, $23.50

It will be ofparticular value to physiologists, biol-ogists, neurologists and other personsinterested in the effect of low-fre-quency magnetic and electric fields oncommunication processes in human,animal and plant life. Widespread useof devices producing emanations in theenvironment can damage living sys-tems, and this volume considers therelated important and critical prob-lems. It covers six major sections oftopics ranging from nuclear resonanceapplications to microwave radiometictechniques followed by groups ofquestions and answers.

Applications are invited for the following positionis:

TWO PROFESSORSHIPS AND ONE LECTURESHIP

One Professorship in Fisheries Biology for candidates with appropriate qualifications andexperience in the fields of Population Dynamics and/or Systems Modeling. Duties will in-clude development of courses and teaching of fishery students in these topics plus researchin an integrated program on fjord fish populations and their ecosystems.

One Professorship and One Lectureship in Aquiculture. There is much interest in aqui-cultural developments and possibilities in northern Norway in which the successful candi-date will have ample opportunity to participate. It is expected that those who are appointedwill contribute to the fjord research program. Although experience in aquicultural tech-niques is required, it is also hoped that the persons appointed will have a broad biologicalexperience so that in both teaching and research they will be able to stress the morefundamental aspects of this stLibject.The University is now considering long-range plans for expansion of its teaching and

research capability in Fisheries Biology. A major program of fishery and environmentalresearch of fjords is being developed by a group of biologists headed by Professor A. H.Weatherley. Other fishery research programs are being planned.Troms0 is situated in a very large northern commercial fishing region, and fishery biology

is one of the areas of stLidy being emphasized in the development of the university. Thework of the fishery group is being conducted in conjunction with marine biologists, fisheryeconomists, sociologists, and technologists, and fishery biology will be offered at bothundergraduate and graduate levels. English may be ulsed for teaching until Norwegian islearned.The University is new and expanding rapidly, and those who obtain posts will be ex-

pected to participate in planning activities. The fishery group is part of the Institute ofBiology and Geology and is housed in a new building well equipped for various kinds ofteaching and research.

A new highly sophisticated 112-foot fishery research vessel will be available by 1975.The University has a cotuiptuter center featuring a 64-K Nor. computer, there is a DCT2000 Simulator connected to a UNIVAC 1110 at the University of Bergen, and a DCT 1000Simulator is under construction.Troms0 lies north of the Arctic Circle (latitude 69'), but has a mild climate because of

its coastal position. There are 2 months of midnight sun and 2 months with darkness.There are fine opportunities for oultdoor life.

Salaries: Professor 104.780, Lecturer 69.760 to 87.510 N.Kr. per year. The University willhelp with housing and other problems. Applications shotild be sent by 14 November 1974,including five copies of curriculum vitae and three sets of relevant publications.
