New Instruments

Three new instruments for precision leveling have been developed at the University of New Brunswick: the Photoelectric Laser Level; the Laser/Ni-007, a combination of He-Ne laser with the Zeiss-Jena Ni-007 geodetic level; a Self-Aligning Centering Detector for laser leveling with long sights in a turbulent atmosphere. The instruments have been laboratory and field tested in a differential geodetic leveling and in leveling across rivers. First-order geodetic accuracy has been obtained.

Rutgers University was chartered as Queen's College on November 10, 1766. It was the eighth institution of higher education founded in Colonial America prior to the Revolutionary War. From its modest beginning in the New Brunswick area the University has grown to eight separately organized undergraduate colleges in three areas of the State, with a wide range of offerings in liberal and applied arts and sciences.

As If

The previous M.O. treatment of unsubstituted hexahalides has been modified, taking the results on Faraday effect obtained at the University of Virginia into account. The absorption spectra previously measured of the complexes (M=Os, Ir) trans-MCl4Br2— and trans-MCl2 Br4— are interpreted by a M.O. treatment for the symmetry D4h as electron transfer transitions, including a first-order relativistic (spin-orbit coupling) correction. The concept of holohedrized symmetry is sufficiently valid to allow a description of MCl5Br— and MClBr5— as if they were tetragonal with centre of inversion and ƒac-(or cis-)MCl3Br3— as if they were cubic. It is shown that the ligand-ligand antibonding effects have the same order of magnitude as the moderate difference in optical electronegativity between Cl- and Br-.

Vertical Crustal Movements

A surface depicting linear vertical movements in Maritime Canada was computed from sea-level data recorded by 8 tide guages and 308 mostly disjoint, relevelled segments of the first-order Canadian levelling network. Owing to the sparsity of the available data and their distribution, the velocity surface must be regarded as indicative of the crude features only. The indications are that there is a west-northwest trending belt of faster subsidence across the eastern end of the Bay of Fundy, and that there may be an area of uplift in northeastern New Brunswick. Although the faster subsidence around the eastern Bay of Fundy seems to be well established now, more data are needed to prove or dispel the existence of the indicated uplift.

ZOO*4300 (Marine Biology and Oceanography) is a senior-level field course offered by the Department of Integrative Biology at the University of Guelph. This two-week course is held at the Huntsman Marine Science Centre in St. Andrew’s New Brunswick, Canada. Students enrolled in the course study various aspects of the ecology, behaviour, physiology, biochemistry and genetics of marine organisms using a variety of oceanographic techniques. The course also includes group exercises to study various intertidal and sub-tidal environments as well as boat cruises to collect plankton, benthic invertebrates, marine fish, and to observe marine mammals. The course provides excellent opportunities for students to familiarize themselves with state-of-the-art techniques involved in various branches of marine biology and oceanography and conduct an individual research project. This feature highlights three individual research projects by University of Guelph students. More information about the field course in marine biology and oceanography is accessible at the following link: http://www.uoguelph.ca/ib/undergrad/fieldcourses_marine.shtml.

Optical transitions from two microwave discharge excited states of argon have been observed using cavity ring-down spectroscopy. These transitions originate on the high-lying levels, 3d[1/2] 1° and 3d[3/2] 2° , and terminate on the nf ′[5/2] Rydberg (n = 8 to 22) levels, which, except for n = 8, lie between the 2P3/2 and 2P1/2 ionization thresholds. In total, 24 such spectral lines have been observed. The quantum defect for the f ′ series has been measured and is compared to previously measured values. We observe a nearly threefold jump in line width in going from n = 8 to n = 9, below and above the 2P3/2 threshold, respectively. The line widths are broad and increase monotonically with n (above 9), in contrast to the narrowing of line widths usually observed. We cannot attribute this to a single source but conclude that collisional, quasielastic l-mixing of the nf ′[5/2] Rydberg states plays a significant role.

The Computer-Assisted Learning (CAL) experiences of the Department of Forest Resources at the University of New Brunswick are described. The paper defines the principal benefit of CAL as better students rather than better teaching and states that CAL has contributed to the former by enhancing learning in three important ways: (i) new subjects, not possible before, have been introduced; (ii) certain topics have been dealt with more often; (iii) the delivery of some subjects has been better managed. The paper continues with a discussion of three strategies that were successfully employed in implementing the CAL programme. These strategies are (1) the programme emphasized heuristic CAL activities: probelm-solving, self-discovery and "what-if" learning, as opposed to drill and tutorial exercises: (2) the programme was committed to developing and maintaining appropriate CAL infrastructure: a dedicated and fully equipped CAL laboratory, plus the ongoing support of a CAL specialist to assist and educate faculty in integrating and implementing CAL techniques and. avoid reliance upon imported, often inappropriate, courseware; (3) in a limited funding situation the programme deliberately traded microcomputer quality for quantity, thus maximizing number of students accommodated. The paper concludes with a description of several CAL examples taken from undergraduate courses currently offered at the Faculty of Forestry. Key words: computer-assisted learning, forestry education.

Investigations at the University of New Brunswick into the feasibility of using Skylab/EREP S190-A and S190-B imagery in photo control extension for small-scale mapping are reviewed. Single-image and multiple-image processing are discussed and it is shown that simple space resection procedures give results compatible with more sophisticated aerial triangulation procedures, i.e., Root Mean Square Error (RMSE) values of approximately 60 m to 70 m in X and Y for S190-A photography and 20 m in X and Y for S190-B photography. The results of this study, and those from previous investigations, are used as a basis for recommendations pertinent to future space photography missions and, in particular, the expected performance of the Large Format Camera (LFC), proposed for use in the space shuttle missions of the early 1980s, is reviewed.

Low Dispersion

The University Observatories of München and Göttingen and the Landessternwarte Heidelberg are building in cooperation with ESO two almost identical FOcal Reducer /low-dispersion Spectrographs (FORS) for the ESO Very Large Telescopes. FORS allows low-dispersion multiobject spectroscopy (19 slits) and longslit spectroscopy in the wavelength range of 330 to 1100 nm. A set of standard grisms with reciprocal dispersions of 45 ...230 Å/mm working in the first order are foreseen. With a slitwidth of 1 arcsec the resulting spectral resolutions range from 180 to 1800.For further FORS details see Appenzeller and Rupprecht (1992) and Seifert et al. (1994).The standard grisms are located in a grism wheel in the parallel beam between the collimator and the camera. Seven of eight positions are available for grisms. The free diameter of the grisms is 135 mm to cover the whole field of view of FORS. To avoid reflection ghosts the entrance surfaces are all tilted by .
