particularchallengebecausealmost every structure or system that is designed and built by Civilengineers is unique. One structurerarely duplicates another exactly. Even when structures seem to be identical, site requirements or otherfactors generallyresult in modifications. Large structures like Dams, bridges, or tunnels may differsubstantially from previousstructures. The Civilengineer must, therefore, always be ready and winning to meet new challenges

A contraption that automaticallyfits deer with a pesticide-impregnated collar is helping to tackle the menace of Lyme disease, which is usuallyspreadamong people by ticks that live on the deer. This disease is nowone of the fastest spreading infectiousdiseases in the US and can be fatal. Trapping and treating every deer in a forest with pesticides isnteasy, so a machine has been designedto doit. The animals are lured to a feeding tray where they have to place their heads in a V-shaped trough to get to the food. The machine keeps an open pesticide impregnated collar at the ready, drooping next to the trough where the deer will put its neck, As the animal takes the food, its neck presses down on a switch that triggers a spring-loaded arm. This propels one end of the open collar Over the neck where it meets the other end. The two ends joinusing Velcro, so withinseconds of the animals arrivalcollar is complete.

Time travel has been a favouritescience fictiontheme ever Since it was first used in H.G. Wells's trailblazing novel The Time Machine. But not everything it describes is science fiction: travelling forward in time, For example, is a proven fact. Einstein's theory of relativitypredicts that an observer moving relative to Earth can leap into Earth's future; and the effect has been confirmedusing atomic clocks. Dramatic time warpsrequirespeeds close to that of light, which is possible in principle but would take a majorfeat of engineering, not to mention a lot of money. Going back in time is far more problematic. Relativity does not rule out an observer being able to make a journey through space-time and return to their past. But all scenarios so far discussed require exotic circumstances.
Our understanding of submarine volcanic eruptions has improved subntially in the past decadeowing to the recentability to remotelydetect such events and to respond rapidly with brief surveys and sampling at the eruption site. But these data are necessarily limited to observations after the event. In contrast, the 1998 eruption of the Axial volcano on the Juan de Fuca ridge was monitored by on site sea-floor instruments. One of these instruments. which measured bottom pressure, was overrun and entrapped by the 1998 lava flow. The instrumentsurvived and was later discovered. The datarecorded by this instrumentreveal the duration, character and effusionrate of an eruption on a mid-oceanridge.

There are about forty distinctkinds of wild cats known to inhabit the earth today. They range in size from the mighty Siberian tiger to several little spottedspeciesabout the size of the averageddomestic cat. The cats are the most efficientlandpredators left on earth. They combinepower, speed, patience, camouflage, and considerable individual skill. All swim well, most climb with greatagility, and at least for short distances, most can move with amazingswiftness. The African lion can reach a speed of almost forty miles per hour when it charges.
