The results of experimental work carried out on culvert inlet efficiency at the University of Saskatchewan are reported in this paper. Efficiency is reported in terms of coefficient of discharge when the culvert operates with inlet control, and in terms of the coefficient of entrance loss when the culvert operates with outlet control. A larger coefficient of discharge or a smaller coefficient of entrance loss represents a higher efficiency. Seven different culvert inlets were tested for both inlet and outlet control, and for the headwater level both above and below the elevation of the crown of the pipe at the inlet. The results are reported in nondimensional charts. Key words: culvert flow, inlet control, outlet control, efficiency, head losses, capacity.

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.

This paper will summarize the experimental work at the University of Chicago on the problem of the onset of thermal instability in a layer of fluid heated from below. The purpose of this work has been to test certain theoretical predictions of the Rayleigh number at which instability sets in, and to determine the type of instability which appears at the critical point. The earlier experiments of this series were done at the hydrodynamics laboratory of the University of Chicago in connexion with a program of meteorological reseach[1, 2, 3, 4]. The current work is being done at the newly organized hydromagnetics laboratory of the Enrico Fermi Institute of Nuclear Studies. This laboratory utilizes the magnet of the old Chicago cyclotron, with pole pieces 92·7 cm in diameter and a gap of 22·1 cm. The magnet was reconstructed to allow the field strength to be varied from 0 to 13,000 gauss; the field is uniform to better than 1 % over the experimental area. The new laboratory is under the administrative supervision of Professors S. K. Allison and S. Chandrasekhar; the experiments are being done by Y. Nakagawa. The theoretical investigations are primarily the work of Chandrasekhar[5, 6, 7, 8, 9, 10] and it will be convenient to review some of his results before discussing the experiments.

Head and pressure changes were studied at manholes with a 90° bend. For pressurized flow, such changes depend only on junction geometry. Among junction parameters, the benching was found particularly important. Full benchings reaching to the pipe crown produced the lowest head losses, particularly when combined with an enlarged pipe diameter at the junction. Head changes in open-channel flow were significantly smaller than those in pressurized flow. Key words: head loss, manholes, sewer junctions, sewer design, sewer hydraulics.

Abstract A new division of the Suez Canal in Egypt, termed the New Suez Canal, was opened for international navigation in August 2015. It is therefore important to ensure the safety of ships navigating this new section of the canal. Measures to avoid grounding and/or drifting to the canal banks are necessary. Additionally, accurate prediction data for ship squat and under keel clearance is crucial. This paper presents the results of experimental work carried out at the Kelvin Hydrodynamic Laboratory at the University of Strathclyde, Glasgow, to study the effect of trim on containership sailing characteristics in shallow waters using Kriso Container Ship (KCS) model. A series of model tests were conducted to measure the resistance, sinkage variations with speed, water depth and loading conditions under different trimming angles at 1:75 scale. The objective of this work is to examine the range of ship trim for safe and efficient sailing in restricted water in both depth and width. The study also aimed to provide data to be used in validating numerical computations to be carried on the same type of vessel to detect the best trim angle for ships during sailing in restricted waters to reduce resistance and therefore fuel consumption. For depth Froude numbers higher than 0.4, the results show that the ship model sinkage is less for aft trim than for level trim or forward trim. Concurrently, it can be observed that there is less water resistance for aft trim than for forward trim, albeit level trim shows the least resistance. The test was conducted for one value of model draft which was 0.144 m. Side bank effect were also examined.

Le but principal de cet article est de montrer les principaux problèmes de la lexicologie moderne aussi que d’améliorer l’enseignement de la lexicologie comme cours universitaire en tenant compte de nouvelles théories apparues à la fin du XXe siècle. L’enseignement moderne exige l’introduction de nouveaux termes comme éponymie, énantiosémie, méronymie, etc., et la révision des théories et des thèmes dits classiques comme polysémie, évolution sémantique, formation du mot, emprunt.  L’auteur se propose de montrer le développement des théories et des approches lexicales au cours des XXe et XXIe siècles. On estime qu’il faut fournir aux étudiants des renseignements sur les nouvelles orientations et les différentes méthodes existant dans la linguistique contemporaine, avant tout sémiotiques, cognitives, discursives, contrastives, même si elles sont présentées sous diverses versions parfois contradictoires. En même temps, une consultation des manuels de lexicologie montre que plusieurs phénomènes connus restent en marge de leurs études, il s’agit avant tout du calque, du mot international, de l’occasionnalisme, de l’archaïsme sémantique, etc. Donc, l’emploi et la définition corrects du terme, la précision de ses particularités au sein de son paradigme sont indispensables pour l’étude lexicologique contemporaine. L’approche principale est de présenter le vocabulaire français en tant que système spécifique d’unités nominatives. Teaching FFL lexicology: opening new approaches The main aim of this paper is to show major problems of modern lexicology as well as to improve the teaching of lexicology at the university by taking into account new theories that appeared at the end of the 20th century. Modern education requires the introduction of new terminology such as eponymy, enantiosemy, meronymy, etc., and the revision of the so-called classical theories and themes such as polysemy, semantic evolution, word formation or borrowing. It is also essential to introduce several topics and approaches including, above all, field theory, connotation theory, the problem of the concept, cognitive semantics, prototype theory and stereotype theory, linguistic and cultural aspects, semantic universals, etc. We seek to identify the main problems posed by the study of French vocabulary, to show the development of theories and lexical approaches during the 20th and the 21st centuries. It is thought that students should be provided with information on the new orientations and methods existing in contemporary linguistics, primarily semiotic, cognitive, discursive and contrastive, even if presented in different or even contradictory versions. At the same time, an overview of lexicology textbooks shows that several rather well-known phenomena remain on the margins of study; these include calques, international words, occasionalisms, semantic archaisms, etc. Therefore, adequate definitions of terms and their use, precise identification of their peculiarities within relevant paradigms in contemporary studies of lexicology are indispensable. Key words: lexicology; French; teaching; approach; theory of the word.

The use of ICT in education has changed substantially over the last two decades. The development of new technologies has enabled us, the users, to mature and gain experience. The introduction of ICT in the educational process at the same time means a change of the teachers' role. The teacher appears in the role of a mentor who directs the activities of the learner. There has been a change in the teacher preparation to teach. He should provide both the content as well as technical support and to create a suitable learning environment. The way of teaching in the natural science and engineering education is specific due to the need of transfer knowledge into the practice. The nature of work in this kind of education requires more experimental work, based on individual learning process. There are many different implementation options of laboratory exercises that advantageously incorporate ICT into the nature of their work. The most popular in engineering education are two different types of laboratories: Simulation (virtual) and Remote controlled (online) labs, defined by Balamuralithara and Woods (2009). A remote controlled laboratory for conducting remote experiments at the University of Maribor, Faculty of Mechanical Engineering was developed. Development of the remote lab was carried out as an exploratory work of the group of students and professors. The lab was developed in the following three phases: development of the construction with corresponding technical documentation, development of the control system and development of the system for remote control of a lift. The successful student project is evident through the applicability of the developed laboratory that serves as a great tool for studying and offers all the benefits of ICT. Key words: experimental work, higher education, learning environment, pedagogy 1:1.
