Echolocation

Bats are capable of avoiding obstacles that they encounter, even in complete darkness. This is because they emit ultrasound (high frequency sound) and analyse the echo produced when the sound hits objects on their path. This article describes the hunting flight of bats and how echolocation is useful in prey capture. Prey capture without the aid of echolocation by some bats is also described.     

Comparative study of Anaplasma parasites in tick carrying buffaloes and cattle

INTRODUCTION The world population of buffaloes(Bubalus bubalis)has been estimated at over172million head,more than97%(167.6million)of which are in Asia and the Pacific region,mainly in India(97.7million)and Pakistan(25.5million)(FAO,2004).About98%of buffaloes in the region are raised by small farmers owning less than two hectares of land and less than five buffaloes(Mudgal,1992).In general,the water buffalo is regarded as more productive,healthier and more useful than the cow,especiall…     

Problems Associated with Multi-Media Data Bases

Education is intimately associated with communication, and so may utilize any technology that is able to support a process that enables information to be transferred from one location to another. This paper describes the meaning of the term multi-media data base and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined.     

Media counseling: A new frontier for health professionals

The authors are co-hosts of a popular open line radio show in Western Canada. In this article the term media counseling is explored and strategies in bringing expertise from the fields of Psychology and Psychiatry to the public are outlined. The authors have been convinced of the value of their approach, and outline purposes, as well as providing data relevant to this radio show That's Living.     

Developing Research Skills for Civil Engineers: A Library Contribution

A cowse‐integrated programme of library instruction has been developed for the School of Civil Engineering at the Queensland University of Technology, Australia; library instruction being one of the means selected to improve the research efforts of fourth year project students. The programme has been developed through consultation between the Civil Engineering Research Project Coordinator and the Civil Engineering Reference Librarian. Its aims are derived from those established for the fourth year research projects. Attention is focussed on the nature of the programme and the impact of instruction on fourth year research project students. Students who had received extended library instruction were compared with students from the previous year. Evidence suggests that the instruction has improved the information seeking behaviour of the students and their literature reviews.
